Abstract: An osteosynthetic pressure plate includes a slot formation for receiving a bone-fixing screw which is adapted to be secured to a bone part which is to be mended. The slot is formed with an edge which includes an oblique portion or ramp having an inclination such that when it is engaged by the underside of a head portion of a bone-fixing screw there will be a displacement of the pressure plate in a direction to move the ramp portion away from the fixing screw and to cause the plate to apply a pressure to hold the bone parts in tight engagement. The plate is advantageously useable with screws having heads of spherical form or conical form, for example.

Abstract: When hanging from a conveyor line, cleaned eviscerated, whole poultry is stiff and in a "rigor mortis" type condition. This condition makes it very difficult to compress the stretched-out, stiff bird into a compact, plumb-appearing shape so that it can be readily placed into a bag for further packaging. Disclosed herein is a method and apparatus in which a cam actuated tray picks up the bird while it is hanging from shackles, and pushes the bird towards its legs so that the legs are forcibly flexed and the stiffened condition is overcome. Once this initial flexing takes place the legs can easily be repositioned either manually or on most automatic loading equipment.

Abstract: In a device for carding, cleaning or opening fibre tufts. An improvement comprises two or more rotating working members or organs (1, 2, 3) which have intersecting planes of rotation and they are arranged to make the fibres fed in at one end move in addition in an axial direction and pass through the lines of close proximity repeatedly in several changed planes of rotation, so that the fibres are worked by a high proportion of the working points before being doffed at the other end or "out" feed. In relation to the dimensions of the working members or organs, the fibres can dwell on the average a longer time in the device so modified and come into contact with a greater proportion of the wire points or pins in the system. This provides for and makes adequate processing of the fibres possible particularly with smaller units in comparison with conventional systems.

Abstract: The high resistance of diffused electrical interconnection lines used for ground return paths in MOS field effect transistor (MOSFET) arrays limits their size and performance. Advantage is taken of the extra interconnection level available from conventional double-layer-polycrystalline silicon (polysilicon) processes to distribute ground potential to arrays, by means of a polycrystalline grid with direct contact to diffused electrodes therein, thus greatly reducing the deleterious effects of ground resistance. The proposed ground grid is integrated into the structure of a MOSFET ROM using a typical double polysilicon process. The first polysilicon level provides the conductive medium for said ground grid and the diffusing doping impurities that form contiguous source electrodes for the array MOSFETs. Gate electrodes thereof and word lines are formed out of the second polysilicon level. Drain electrodes are diffused and contacted by metallized output lines.

Abstract: A process for placing non-continuous Dual Electron Injection Structures (DEIS) between two layers of polysilicon used to form an array of poly devices on an integrated circuit substrate. Separate masks are used to define Poly 1 and Poly 2 devices, respectively. The DEIS structure is disposed above the poly 1 devices. A silicon nitride (Si.sub.3 N.sub.4) layer is used to mask the DEIS structure and prevents it from oxidizing during certain processing steps. A thin layer of poly x is placed between the DEIS structure and the Si.sub.3 N.sub.4. The poly x layer forms a buffer and protects the DEIS during an etching step which removes the Si.sub.3 N.sub.4 layer.

Abstract: A process for reducing the particle current in the sub-gap range of all-Nb Josephson junctions. The process results in junctions having substantially increased values of V.sub.m. In order to reduce the single particle current, the reaction between the barrier layer oxide and the counter electrode is prevented by additional process steps. After forming the tunnel barrier (4) and before depositing the counter electrode (9), the tunnel barrier surface is covered with a thin, non-continuous layer (5) of a material such as gold which is not reacting with oxygen at process conditions. Subsequently, the non-covered barrier layer surface regions (7) are strongly oxidized thereby forming an oxide layer (8) of sufficient thickness to prevent electron tunneling in these regions.

Abstract: After a silicon layer is selectively grown on that part of a silicon substrate surface on which an electrode is to be formed, the silicon layer is reacted with a refractory metal so as to form the electrode made of a metal silicide layer.
