Title: Acoustic convolver
Inventor: PAIGE EDWARD GEORGE SYDNEY
IPC: G06G7/195
Filed: 1984-02-15
Abstract: An acoustic convolver 20 comprises a piezo-electric substrate 21 and input transducers 23 and 24 arranged such that the bilinear polarization field PNL arising from acoustic wave interaction has a component 22 polarized both parallel to the substrate surface and transversely of the input acoustic wave vectors. This makes it possible to locate output electrodes 25 outside the interaction region 26, reducing spurious signals from self-convolution of acoustic waves with reflections from electrode discontinuities. The output electrodes 25 of a degenerate-mode convolver 20 are located either side of the interaction region 26. The piezoelectric substrate 21 is of Y-cut lithium niobate arranged for acoustic wave propagation at 23 DEG  from the Z-axis. A non-degenerate mode convolver has a periodic electrode structure 30 arranged so that coverage of the interaction region is small and unlikely to generate any significant spurious output. <IMAGE>

Title: Ramp bridging device
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1984-06-25
Abstract: A bridging device comprises a pivotable bridge plate (1) having a pivotal or retractable and extensible extension portion (4) on its free end, in which the bridging device is caused to return to its inoperative position when a vehicle having a platform (5) to be loaded or unloaded leaves the vicinity of the ramp. To effect this the bridging device is provided with an ultrasonic detection system (11, 12) for detecting the presence of a vehicle, which system is disposed in the region of the free end face of the bridge plate (1).

Title: High voltage resistant members and method for producing same
Inventor: WHEELER EDWARD S
IPC: B29C48/06
Filed: 1985-01-24
Abstract: A method of producing high voltage resistant members employed in electrical installations such as bushings and insulators comprises extruding a sheath of unvulcanized elastomer on a core, which for example is a fiberglass rod, and mounting vulcanized sheds on the sheath therealong, then vulcanizing the sheath to form an integrated high voltage resistant member. The sheds may be stretched on a mandrel at room temperature and then chilled prior to insertion upon the sheath; subsequent warming shrinks the sheds for a tight grip on the sheath. The sheds also can be molded directly onto the sheath together therewith in steps along the length of the core. For producing a bushing, the sheath is placed on a core formed of a conductive stud wrapped with paper and metal foil and then impregnated with a suitable hardenable resin.

Patent GB-2190737-A (GB)
Title: Heat transfer panel
Inventor: EDELSTEIN FRED
IPC: F28D15/04
Filed: 1986-05-19
Abstract: A thermal management system using heat pipe principles and incorporating capillary-pumped equipment mounting panels such that a heat transport loop without moving parts is provided. The panels can function to either absorb heat or to reject heat and can interface with heat generating equipment or heat radiators. Each panel comprises a pair of coextensive flat plates bonded together with a thin, fine-pore sheet wick interposed therebetween. A network of liquid grooves in one plate is in fluid communication with the sheet wick which covers the grooves and most of the plate and a separate liquid line connecting the panels. A network of vapor channels in the other plate is in fluid communication with the wick and with a separate vapor line connecting the panels. The vapor channel networks of the panels and the liquid groove networks of the panels are connected such that the panels are arranged in parallel in the fluid circuit or loop. A heat input into panels in the loop causes evaporation of liquid off the surface of the sheet wick. Vapor from the evaporated liquid is circulated to panels serving as cold sinks where the vapor is condensed. Capillary action of the wicks returns the condensate to the panels being heated where the cycle is repeated.

Patent GB-2187338-A (GB)
Title: Insulation stripping device
Inventor: MAACK WERNER
IPC: H02G1/12
Filed: 1987-02-11
Abstract: The apparatus comprises a fixed insulating severing first blade (8) and a movable insulation severing second blade (24), having co-operating V- shaped cutting edges (46). The second blade (24) is movable towards the first blade (8) by means of a ram (44). An insulation step (14) is movable with the second blade (24) to engage the insulation (1) of an insulated wire (W) to limit the penetration of the severing blades (8 and 24) into the insulation (1). The apparatus can thus automatically adjust to variations in insulation thickness without damage to the wire core (C). The shape of the cutting edges (46) ensures that with larger gauge insulation, the insulation (1) is still adequately severed. <IMAGE>

Patent GB-2206606-A (GB)
Title: Non-ferrous metal recovery from slag
Inventor: KAIURA GARY H
IPC: C22B23/02
Filed: 1988-05-27
Abstract: Metal values in non-ferrous metallurgical slag are recovered by gently agitating the slag in contact with matte using stirring energy dissipation rates insufficient to emulsify slag in matte. These low agitation rates conserve energy by reducing cooling of the charge, especially by reducing the period required for the slag and matte to separate out into distinct layers after agitation. The preferred low energy dissipation rates increase the efficiency of the value metal recovery and avoid or reduce impairment of the reducing capabilities of the matte and hence its capabilities for reducing and collecting oxidized value metal species from the matte. This is achieved by avoiding or reducing oxidation of the matte as a result of dispersal of the oxidation-protective overlay of slag and contact of the matte with the ambient oxidizing atmosphere.
