Title: Ensuring directivity in charge transfer semiconductor - compact arrangement of floating and commanded electrodes excluding reversed feed
IPC: H01L21/339
Filed: 1974-08-02
Abstract: A semiconducting device for charge transfer, comprises a substrate of semiconducting material, a first isolating layer on the substrate layer, a first set of electrodes on the isolating layer, to be connected to a diphase source of tension, a second isolating layer on the first set of electrodes, and a second set of electrodes on the second isolating layer. A part of each electrode of the second set is positioned so as to overlap partly is fellow electrode of the first set; the electrodes of the second set acting as floating electrodes with which there is no electrical connection. A memory constructed according to the invention can be very compactly assembled on a chip with the maximum of space being used for the electrical conductors and the connections. The floating electrodes are capacitively coupled to the commanded electrodes across a layer of oxide so as to maintain a difference of potential between each floating electrode and the commanded electrode with which it works. This difference of potential acts to form a shoulder preventing the reversal of the charge when it is transferred from the zone below an adjacent electrode.

Title: Hardening of saw teeth - by selective heat treatment with control of base temp.
IPC: C21D9/24
Filed: 1975-08-29
Abstract: The saw is pretreated so that the main part of the saw tooth is held at a definite prescribed low temp. During or after the transfer of the tooth in an atmosphere at a definite low temp. the surface layer is heated.

Title: High speed bar shearing tool - has cam to release locking lever and actuate system of wedges to clamp and position billet support
IPC: B23D23/00
Filed: 1976-04-01
Abstract: A bar shearing tool for use in a press has the bar (B) fed through a clamp (24) against a backstop (30). The press bears down on the platten (10) which carries the cutting blade (48). As it descends and contacts the billet, the cam (28) releases the cocking lever (26), allowing the spring mechanism (12) to move towards the press. This acts through a wedge to clamp the bar during shearing. At the same time, a wedged pin (36) is pushed down moving the billet support (32) into position. When the shearing stroke is completed the support is pulled clear allowing the billet to clear. As the press reaches the top of the stroke the cocking levers (26) are reset allow the bar to be fed for the next cut.

Title: Cutting of strips from cattle intestines - which are floated on water and cut by rotating blades without preliminary cleaning
IPC: A22C17/14
Filed: 1977-02-11
Abstract: Cutting machine is used for prodn. of strips from the small intestines of cattle for the mfr. of surgical catgut, tennis racquets strings and strings for musical instruments; the strips are cut under water without being sepd. from the assembly to which the intestines are attached and without any preliminary removal of excrement. The machine comprises a large, constant level tank, contg. water in which the digestive appts. of the animal, between the stomach and the anus can float; this enables the easy positioning of the intestine on the cutting guide; this has slits for the peripheries of the circular cutters which are driven by the electric motor. The intestines are placed in the water and float because of the surrounding fat. The operator seizes one end and threads it on the guide; the motors are started and the intestine pushed over the guide to reacht the cutters. The cut strips are seized by hand and pulled towards the pulley. This is driven by the motor and draws the strips forward to fall into the container. Providing that the intestine is sufficiently firm, the longitudinal cutting operation can be effected automatically along the whole length of the intestine. As the latter is floated on water it is automatically washed thus avoiding the long and delicate operation to remove any excrement.

Title: Firing range target with increased life - is mounted on spindle to swing when struck, while travelling along track
IPC: F41J7/04
Filed: 1977-03-31
Abstract: The target, used for any suitable type of firearm, can be shaped as the silhouette of a tank, and moved along a track. This shape can be supported on a tube with bearings mounted inside each end, and able to travel along a spindle forming part of the track. This allows the target to swing when struck, thus indicating a hit. Part of the energy of the shell is therefore absorbed, but the length of life of the target is almost limitless. Thus, it can be made of mild steel instead of stainless steel etc. as in the conventional construction.

Title: Tunnel lining ring installation - uses carrier ring behind cutting head to assemble channel section segments into complete ring
IPC: E21D11/22
Filed: 1977-05-04
Abstract: The application of tunnel lining rings to a mineshaft immediately behind a full diameter cutting head, includes the use of a carrier ring (25) to build up a channel ring made from five equally sized trough section channel segments (4, 5 etc.). Each segment is mounted in turn on the carrier by special clamps, secured at an angle in a tangential manner to the inside edge of the carrier, and the latter is rotated in alternate directions to force the ends of the segments against one another after their ends have been overlapped. The complete ring is then separated from the carrier and mounted around the gallery face, being held there in tension.

Title: Warp-knitted belt for e.g. trousers or skirts - contains tensioned yarns which, on heat treatment, produce a curve across belt width to withstand flexure
Inventor: GROSHENS PIERRE
IPC: D04B21/20
Filed: 1977-08-02
Abstract: A strip of warp-knitted fabric, resistant to bending across its width, is prepared for a belt intended for trousers or a skirt. The resistance to bending is increased by providing a curved shape, conferred by the heat treatment of tensioned yarns. The curve or contour is produced in opposition to the possible flexing effect. The strip provides a bowed effect which is stable and permanent, and withstands the transverse folds which usually form during wear.
