A heavy duty, large self-forming socket having a plurality of retractable gripping pins bundled in parallel and held in a frame within a housing is disclosed. The frame is positioned axially within the housing by radially extending, elongated hold elements that are positioned circumferentially around the housing. Slots in the housing exterior allow efficient inspection of the position of holes into which the hold elements are installed. A collar with shelf around the center pin protects the bias spring for the pin from over-compression. The gripping pins may be held to the frame by spring clips. An adaptor is attached wherein a secondary operation is used to remove the adaptor from the square end of the socket. The self-forming socket is well suited for use with valves and controls for water, gas, sewage conduits and piping.

A self-adjusting variable grip locking plier for gripping a workpiece. The plier includes a body, a handle, and a wedge. The plier is designed for extremely fast set up and for easily gripping and holding the workpiece with one hand with absolutely no adjustments ever to make, and provides a larger than ordinary jaw capacity in a very compact design. The plier grips and holds the workpiece with a light or tremendous gripping force with no adjustments ever to make, and with an extremely fast unlocking system, while at the same time fitting into the palm of one hand. When the workpiece is grasped, one simply ratchets the handle until the desired grip is obtained. The more times one squeezes the handle the tighter the grip. This automatically locks the plier at the desired grip. To release the plier one simply pushes the wedge back into the body with the palm of one hand.

A medical fluid injector, replaceable syringe, and coupling mechanism to engage the syringe plunger to the plunger drive ram of the injector are provided wherein coupling involves a cam cleat-like mechanism, thereby allowing for cooperative movement between the plunger drive ram and syringe plunger. The coupling mechanism of the plunger drive ram is provided with first and second movable members, each having toothed, arcuate surfaces, while the coupling mechanism of the syringe plunger is provided with a knurled extension. Disengagement of the coupling mechanism is facilitated by translational movement of a face plate located on the forward end of the injector housing.

A cam lever operated accessory gripping mechanism the gripping mechanism includes a cam lever, a threaded stud, a dowel fixed to a first end of the threaded stud, first and second relatively movable main body sections, the first of the main body sections including a handlebar bracket extension, a first clamping jaw for engaging a first side of the accessory, and an opening shaped to slidably receive the second main body section, and the second main body section including a bore and a slot for receiving a fastening member into which the threaded stud is threaded, and a second clamping jaw for engaging a second side of the accessory. The dowel is rotatably mounted in the camming lever, which has at least one overcenter camming surface that engages a cam-engaging surface of the first main body section, such that pivoting of the camming lever about the dowel in a first direction causes the dowel holding section of the camming level to move in an axial direction of the threaded stud, pulling the second main body section against a biasing force provided by a biasing spring extending between the first and second main body sections, in a direction that causes the second clamping jaw to move towards the first clamping jaw and thereby grip the accessory. Adjustment of the gripping mechanism to fit different accessories is accomplished by turning the threaded stud to cause axial movement of the follower insert and corresponding movement of the second main body section is a desired direction, to adjust the initial spacing of the first and second clamping jaws.

Pliers with parallel jaws include an upper portion having an upper jaw of upper teeth, a lower jaw portion having a lower jaw of lower teeth.

A novel panel-mountable fiber optic cable feedthrough is described that has two main body parts that can be brought together around single or multiple fiber optic cables and secured in place to prevent slippage of the cable(s). Use of two such main body parts that split along a plane that passes through the axis of the fiber optic cable(s) allows joining the two main parts at any position along the cable(s) without the need to thread the cable(s) through a one or more pre-formed cylindrical cavities in the body of the feedthrough. The main parts for this fiber optic feedthrough can be made by plastic injection molding suitably shaped to relieve bending strain in the glass optical fiber(s) within the cable(s). The foot-print for mounting such a feedthrough can be made compatible with that of a number of popular fiber optic connector mounts, including the SC-connector.

An image-taking device is capable of effectively utilizing a shake correcting section and thereby shooting an image with little blur. The image-taking device includes: an angular rate sensor which detects a shake; a shift lens which travels within a predetermined moving range to correct the shake; a shift lens driving section which pulls the shift lens, which has moved to a biased position from a predetermined center, back to the center; a central processing unit which calculates a correction effect for the shake; and a liquid crystal monitor. The central processing unit calculates the correction effect based on a distance between the position of the moved shift lens and the center, and displays the correction effect on the liquid crystal monitor.

A fastener connects two strings together, such as the drawstring of sweatpants or the two shoe lace strings ends of respective shoe lace strings in a pair of sneakers. The body of the fastener is made out of a material, such as highly dense polyurethane foam, that is strong, yet flexible, or of a rigid plastic, that is strong, yet flexible. The two strings to be fastened pass through one or more gripping and/or locking holes in the fastener body. When the shoelace is passed through the gripping and/or locking holes, the dense polyurethane foam grips the lace tightly. The free ends are pulled through one or more peripheral slits extending towards, but not all the way to, the gripping and/or locking holes and then bent against the upper outer surface of the disk and locked in place in the respective one or more peripheral locking slits.
