An ultralight unit load device has a ruggedized quadrangular composite structure with a cellular load-bearing core sealed in successive ordered-polymer stiffening plies and trimmed at the outer edges with a hollow, multi-chambered profile of lightweight material fixed with a flush attachment member so as to present a flat surface for easy loading and unloading.

A bag is made with a combination of mesh and film on both the front and back sides. For use with automatic filling machines, one side of the bag has a wicket strip with wicket holes to receive the wickets from the filling machines. If pneumatic or vacuum systems are used for bag opening, a fluid impervious assisting strip is bonded to the mesh wall at the bag mouth. A method of making such a bag includes the use of a continuous film web with adjacent continuous mesh webs. A linear seal joins the film web with the mesh webs after which the web is folded so that the free edges overlie each other. A transverse seal followed by a transverse cut results in a finished bag.

Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes the steps of: removably positioning a first terminal edge of a first conduit portion with a first terminal edge of a second conduit portion; facing the terminal edges of the first conduit portion and the second conduit portion; aligning the terminal edges of the first conduit portion and the second conduit portion; melting at least a portion of the terminal edges of the first conduit portion and the second conduit portion; engaging the melted terminal edge of the first conduit portion with the melted terminal edge of the second conduit portion; maintaining pressure between the engaged terminal edges, thereby creating a fused joint area; and removing at least a portion of the resultant external bead extending around the fused joint area. A fusion apparatus for employing this method is also disclosed.

A device (10, 50, 60, 70, 80, 90) is used to apply an electric pulse or spike to a patient to treat the patient. The device can have a series of preset treatments programmed therein. A user can select a treatment from menus displayed on a display (100). The impedance of the skin and underlying tissue to be treated can be measured prior to the treatment to locate active areas on the skin for treatment. A variety of probes can be used with the device, with the device automatically detecting the type of probe attached. Multiple electrodes can be used on the probe, which allows the active areas in contact with the probe to be identified prior to treatment to allow the treatment to concentrate on the active areas.

A revolver with light-weight firing control housing includes a cylinder frame supporting a rotatable cylinder defining a plurality of cartridge-receiving chambers and a firing control housing made of a non-metallic material. The firing control housing attaches to the cylinder frame and supports firing control mechanism components, such as a trigger and a pivotable hammer actuated by the trigger. In one embodiment, the firing control housing may be made of a polymer and the cylinder frame may be metal.

A revolver with latching mechanism for swing-out type cylinder. The revolver includes a frame, a rotatable cylinder movable from a ready-to-fire position in the frame to a loading position laterally displaced outwards from the frame, and a latching member retained in the frame by a barrel insert that defines a bullet bore. In one embodiment, the latching member may be a spring-loaded plunger movable from a locked position in which the cylinder is locked in the ready-to-fire position to an unlocked position in which the cylinder is movable to the loading position. A cylinder crane pivotally mounts the cylinder in the frame and moving the plunger to the unlocked position allows the cylinder crane to be swung out laterally from the frame by a user. In one embodiment, the plunger is held in the frame by a retaining plug engaged by the barrel insert.

A roof structure for greenhouses, which, through having a simple arrangement for improving lighting, is capable of retaining the same strength as in the conventional roof structure for greenhouses. A plurality of rafter members in the form of metal pipes of circular cross section formed in arch shape with a pipe diameter of about 30 mm to about 50 mm, are arranged in the direction of the roof ridge at intervals (P) of about 0.5m to about 1.5m. This makes it possible to simplify the construction of the aggregate constituting the roof while retaining a predetermined strength. That is, simply joining the rafter members by ridge pieces provides a sufficient strength to withstand vertical and horizontal loads applied to the roof; therefore, purlin members can be dispensed with. Further, since the construction of the housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.

The invention provides an internal and external corner plastic template. The internal and external corner plastic template is structurally characterized in that edge frames are respectively arranged on a long edge and a short edge on the reverse side of a panel, an edge sealing side plate is arranged on the other short edge on the reverse side of the panel, a side rib plate is arranged on the other long edge on the reverse side of the panel, an extension plate which extends out from the panel is arranged on the outer side edge of the lower edge of the side rib plate, the extension plate is an external corner connection plate, strip holes used for connecting the external corner connection plate with other templates in butting mode are formed in the external corner connection plate, the edge sealing side plate extends to one end of the external corner connection plate, exposed on the exterior of the panel, and is flush with the outer side edge of the external corner connection plate, a rectangular flat plate is arranged at an inner vertex angle of a connection position of the extending end of the edge sealing side plate and the side rib plate, the rectangular flat plate is an internal corner connection plate, and square holes used to connect the internal corner connection plate with the other templates are formed in the internal corner connection plate. The internal corner connection plate and the external corner connection plate are respectively connected with edge frames of the other two templates, and then an internal and external corner is formed. Faces of the internal and external corner are tightly connected, and then shaping quality of concrete is guaranteed.

A green compact according to the present invention is obtained by compression molding raw material powders having a metal powder as a primary raw material, wherein an oxide film is formed between the raw material powders that constitute the green compact, thereby binding the raw material powders to each other. The green compact is characterized in that a powder having a circularity R of 0.75 or higher at a cumulative frequency of 80% is used as the metal powder. Here, the circularity R is represented by numerical formula (1), where the two-dimensional projected area of the metal powder is denoted by S and the two-dimensional projected circumference of the metal powder is denoted by L.

The invention discloses a floating grinding method and fixture; the floating grinding fixture comprises a lathe spindle clamping jaw, a grinding rod, a floating grinding fixture and a lathe tool rest; the lathe spindle clamping jaw clamps the grinding rod for rotating; the floating grinding fixture comprises a motor, a frequency converter, a magnetic rotating head and a speed control switch; the motor is electrically connected with the frequency converter; the magnetic rotating head is mounted on a front end of a main shaft of the motor; the floating grinding fixture is mounted on the lathe tool rest; the lathe tool rest reciprocates in a straight line to drive the floating grinding fixture to move; the magnetic rotating head is coaxial and consistent with an axis of the grinding rod clamped by the lathe spindle gripping jaw; the magnetic rotating head of the grinding fixture is opposite to the grinding rod in rotating direction, and moves at a constant speed; a workpiece ground is in magnetic floating connection with the magnetic rotating head of the floating grinding fixture, and thus is driven by the magnetic rotating head to rotate; a surface of an inner hole of the workpiece is in uniform contact with the grinding rod in a circumferential direction; the workpiece ground is in magnetic floating connection with the magnetic rotating head of the floating grinding fixture, and when grinding is abnormal or resistance increases, the magnetic connection is automatically broken.
