Title: Schottky contacts
IPC: H01L21/285
Filed: 1981-06-24
Abstract: The long term diffusion of Si into an Al contact is reduced by interposing a layer 132 of a transition metal between a thin Al contact layer 131 and a thicker Al top layer 133. The intermediate layer 132 forms a barrier to prevent diffusion of Al between layers 133 and 131 so that the quantity of Al available for reaction with the substrate 10 is small. The Al may contain (eg 2%) Cu, and the intermediate layer may be W, Ti or Cr (eg W 2% Ti). The contact structure forms a Schottky diode which may be used in integrated logic circuits, the same type of contact structure also forming ohmic contacts to suitably doped regions. <IMAGE>

The upper rotor has conditioning brushes 35 for conveying crop and conditioning crop by relative movement between the brushes and the crop. The envelope of brush tips on the rotor may be conical. The population of brush elements may vary with rotor height. The conditioning brushes may be mounted on the conveying surface 19. The upper and lower rotors may be rotated in opposite senses to effect at least partial shear cutting. <IMAGE>

Title: Static metering pump
Inventor: HORAK VLADIMIR
IPC: G01F11/28
Filed: 1981-08-12
Abstract: A static metering pump includes a pair of tanks (12, 14), electrically operated inlet (18, 20) and outlet (32, 34) valves, liquid level sensors (50, 52) and controls (48) which permit the alternate filling of a first of the tanks while permitting the discharging of liquid from a second of the tanks and then permitting the discharging of liquid from the first tank while filling the second tank. The cycle of filling and discharging of the tanks is repeated until a preselected volume of liquid is dispensed with precise metering. The two tanks are adapted to dispense the same volume of liquid in normal operation. Where the total volume of dispensed liquid called for includes a fraction of the normal volume of the tank, one of the tanks is provided with a fractional liquid level sensor which may be preset to fill this tank initially to the fractional volume and to commence the metering operation by the discharge of this tank. <IMAGE>

Title: System for precisely controlling the flow of intravenous and enteric fluid to a patient
Inventor: DANBY HAL C
IPC: A61M5/168
Filed: 1982-01-22
Abstract: A system for providing for the controlled introduction of an infusate from a reservoir (10) into a patient (14) in which the reservoir (10) is supported for gravity feeding and connected to the patient (14) through a fluid passage (16) which has a controller (18). The controller (18) includes a chamber (20) which has one wall in the form of a flexible diaphragm (48) an inflow passage (44) having an output port (50) facing the diaphragm (48) and an outflow passage (46) having an input port (52) facing the diaphragm (48). Flow control is provided by a piston (38) which moves the diaphragm (48) in relation to the input port (52) of the outflow passage (46) and which limits the maximum flow rate out of the chamber (20) to a value which is less than the maximum flow rate out of the chamber (20) when the chamber (20) is in the controller housing (36). When the chamber (20) separates from the controller housing 36 the flow automatically stops as the result of providing an outflow rate which is greater than the inflow rate. To prime the device, a latchable safety arm (54) is provided which, when removed, will change the flow control rate into the chamber (20) to a rate greater than out of the chamber (20). <IMAGE>

IPC: A61F2/06
Filed: 1982-03-02
Abstract: A porous tubular product, suitable for use as a vascular graft, is made by winding polymeric fibres on a mandrel while overlying fibres are simultaneously bonded together. In one embodiment, a viscous solution of a biocompatible polymer is extruded from a spinnaret to form a plurality of filaments which are wound on a rotating mandrel as the spinnaret reciprocates relative to the mandrel. The filaments are wet as they contact each other, so that on evaporation of the solvent the fibres become bonded to each other. Alternatively, molten thermoplastic filaments are extruded which on winding fuse to achieve bonding.

Title: Shower support
Inventor: KNAPP ALFONS
IPC: E03C1/06
Filed: 1982-11-02
Abstract: A shower support comprises a rod 7, supported at both ends and extending vertically, parallel to a wall 1. On the rod 7 there is mounted a slideably adjustable slider 10 carrying a shower head 13 connected by a flexible pipe 14 to a set of taps 2. The set of taps 1 includes an annular member or rosette 5 mounted slideably thereon yet flexable, after installation, in contact with the wall 1 in which the set of taps 2 is partially embedded or encased. To avoid having to pre-arrange a separate support for the lower end of the rod 7, said lower end is connected to the annular member or rosette 5, whilst its upper end 8 is supported by a normal bracket 9. This also guarantees that the rod 7 is held exactly parallel to the wall 1 independent of the depth to which the set of taps 2 extends into the wall 1. <IMAGE>
