A panel has a core of wood material or a wood material/plastic mixture, a top and an underside, and two opposite side edges, which have profiles that correspond to each other such that two identically configured panels can be connected and locked to one another in the horizontal (H) and vertical (V) directions by an essentially vertical joining movement. The locking in the horizontal direction (H) can be brought about by a hook connection with an upper locking section having a hook element and a lower locking section having a hook element. The locking in the vertical direction (V) can be brought about by at least one tongue element that is formed from the core in one piece and can be moved in the horizontal direction (H). The at least one tongue element provided on the lower locking section is free with respect to the core in the direction of the opposite side edge by means of an essentially vertical slot and during the joining movement snaps in behind a locking edge extending essentially in the horizontal direction (H), which locking edge is embodied on a locking projection. The tongue element is connected to the core on at least one of its two ends in the direction of its side edge (II), and the width (B₁, B₂) of the locking edge is different in size over the length (L) of the opposite side edge (I).

Endoscopic instrument management systems are described herein which allow one or more operators to manage multiple different instruments utilized in endoscopic procedures. In one aspect, responsibility for instrumentation management between one or more operators may be configured such that a first set of instruments is controlled by a primary operator and a second set of instruments is controlled by a secondary operator. The division of instrumentation may be facilitated by the use of separated instrumentation platforms or a single platform which separates each instrument for use by the primary operator. Such platforms may be configured as trays, instrument support arms, multi-instrument channels, as well as rigidized portions of instruments to facilitate its handling, among others. In another aspect, one or more plastically deformable instrument manifolds are provided to guide flexible endoscopic instruments into and through an endoscopic access device.

A process for producing semiconductor wafers by double-sided polishing between two rotating, upper and lower polishing plates, which are covered with polishing cloth, while an alkaline polishing abrasive with colloidal solid fractions is being supplied, the semiconductor wafers being guided by carriers which have circumferential gear teeth and are set in rotation by complementary outer gear teeth and inner gear teeth of the polishing machine, which is distinguished by the following process steps: (a) at least one of the two sets of gear teeth of the polishing machine is at least from time to time sprayed with a liquid which substantially comprises water, (b) the alkaline polishing abrasive is fed continuously to the semiconductor wafers in a closed supply device. There is also a device which is suitable for carrying out the process.

Orthodontic attachment devices for interacting with an orthodontic appliance are described. Described herein are orthodontic attachment devices that include one or more features to improve the bonding to the teeth, improve the appearance of the orthodontic attachment device, improve the transfer of force from the orthodontic appliance to the tooth/teeth, improve the connection between the orthodontic attachment device and the orthodontic appliance, improve the ease and ability of removal of the appliance from the teeth, reduce the weight of the orthodontic attachment device, increase the stability of the connection of the orthodontic attachment device on the tooth, and/or reduce the number of steps for applying the orthodontic attachment device to the patient's teeth.

A drawer configured to be extended from and retracted into a furniture body. The drawer includes a bottom part; a front panel; two lateral frames; and a back wall connected via a corner joint to an end region formed with one of the lateral frames. Each corner joint including a first connecting part and a second connecting part pivotably connected to the first connecting part. The second connecting part includes detent means for connecting the second connecting part to either the first connecting part or the back wall. The first connecting part is connected to an adapter associated with the end region formed by the back wall with one of the lateral frames.

The invention relates to a tubular medical instrument having a hollow shaft, a handle positioned on the proximal end of the shaft, and at least one tool actuation element that is positioned in the hollow shaft and has on its distal end a tool, wherein the tool actuation element can be coupled with at least one actuation mechanism of the handle to actuate the tool and wherein the tool actuation element and the hollow shaft can be detachably connected to one another by a coupling mechanism. To create a coupling mechanism that is essentially free of any play and is simple to operate, it is proposed with the invention that the stopping of the coupling mechanism between the tool actuation element and the hollow shaft should be dependent on the position of the tool.

A sandwich structure is provided that includes a corrugated layer with at least one core layer (structure) made of a periodic array of adjacent truncated upward facing peaks and truncated downward facing valleys. Each truncated peak has a bonding land of an area A1. Each truncated valley has a bonding land of an area A2. A ratio of A1/A2 is less than 2. A distance D is between neighboring peaks, and a distance D is also between neighboring valleys. The corrugated layer is made from an initially flat sheet thickness of t. A first sheet layer is physically coupled to bonding lands of the truncated peaks. A second sheet layer is physically coupled to bonding lands of the truncated valleys.

The invention relates to a magnet valve, having a valve insert and a tappet guided movably in the valve insert, having a sealing dome which plunges in sealing fashion into a sealing seat of a valve body, and the tappet is movable counter to the spring force of a restoring spring. According to the invention, a bracing bush, disposed outside a flow path in a bore of the valve insert, which receives the restoring spring and braces it and radially guides it from outside.

A rotor-hub for a rotary-wing aircraft is disclosed. The rotor-hub comprises a yoke comprising a plurality of yoke arms and a plurality of yoke straps, wherein the yoke arms are joined together by the yoke straps, and wherein a plurality of inner walls of the yoke define a central void space. A pitch horn is movably connected to the yoke and a portion of the pitch horn is located within the central void space. A connecting shell is fixedly attached to the yoke.
