Title: Body implantable pacemaker
IPC: H03M1/60
Filed: 1979-07-20
Abstract: A multi-mode pacemaker includes a microprocessor 100 and a memory 102 programmable with a variety of processes for stimulating a heart and/or a sensing and transmitting to an external device conditions of the heart or pacemaker. The microprocessor controls a multiplexer 106 to input via a scaling amplifier and a/d converter 108 signals from atrial and ventricular leads 17, 19, the power source 126, a reed switch 23 operable by an external magnet, or redundant leads on lines 138d,e. The output comprises latch drivers 134 a-d with respective output select switches 130 a-d selectively operable to supply stimulation pulses to the leads or allow sensing. External apparatus 104 may transmit coded information to change the stored program or operation of the reed switch may select a different program starting address. Pulse width, rate and amplitude may be controlled in response to sensed heart activity or power source level and different pacing modes (demand, asynchronous, etc.) or multi-site pacing to disrupt arrhythmias may be selected automatically or externally. In an aid converter 308 (Figure 8), counter 400 counts up the output of VCO 402 controlled by unknown signal V(X) and then counts down to zero the output of VCO 402 then controlled by reference EREF and during such countdown a counter 412 counts clock pulses so that when counter 400 reaches zero the output of counter 412 depends on V(X) but not on the scale factor of VCO 402. <IMAGE>
Patent GB-2030891-A (GB)
Title: Embedding particles in thermoplastic materials
IPC: B29C70/64
Filed: 1979-08-23
Abstract: The invention is concerned with the surface treatment of thermoplastic materials. Certain thermoplastic materials such as polypropylene are difficult to bond to like or dissimilar materials using conventional adhesives. In the invention, particles of dissimilar materials such as glass, PFA, sand, mica, talc, calcium carbonate or copper are embedded in the surface of the thermoplastic material (e.g. fibrillated polypropylene) to meet this problem. Thus, the thermoplastic material at a temperature near to but below the m.p. is bombarded with the particles (e.g. in a fluidised bed) which are at a temperature higher than the m.p. of the thermoplastic material.

Title: Connector for furniture units
IPC: F16B12/20
Filed: 1979-09-04
Abstract: A connector (10) for a furniture unit that has at least two flat members (23, 24/25) to be interconnected at right angles to one another, comprises a resilient member providing a first slot to receive and frictionally hold a section of one of said flat members and a second slot to receive and frictionally hold a section of the other of said flat members. In one form, the connector (10, 10A, 10B) comprises an endless resilient member forming a pair of S- shaped sides (11, 12) to provide a first pair of parallel slots (13/14) which open in opposite directions to one another, the ends of the S-shaped sides being interconnected by transverse parts (15, 16) to provide a second pair of parallel slots (17, 18) which open in opposite directions to one another and extend at right angles to the first pair of slots. Connectors (10, 10A, 10B) according to the invention have been successfully formed from plywood, but may be formed of plastics material, metal tubing, or wire. Alternatively, the connectors (301, 307, 310) Figs. 8-10 not shown may be formed of sheet metal. <IMAGE>

Title: Resiliently covered roller, of roller and ring extrusion pellitising press
IPC: B30B11/20
Filed: 1979-10-30
Abstract: The annular die (1) of the press has extrusion bores therethrough, and is adapted to be rotated about its central axis, whereby material introduced within the die is extruded through the bores by one or more freely rotatable pelletising rollers (6) which each have a resilient plastics material peripheral shell (20) which engages with the inner peripheral surface of the annular die (1), each roller (6) being carried e.g. adjustably on a supporting structure connected to a stationary shaft (5), the die being fixed to a tubular rotor (2) which is rotatably mounted on the stationary shaft (5). In comparison with a hard steel roller, the shell (20) e.g. of non- foamed polyurethane, avoids wear of the die (1), is less costly, has less inertia, and is less susceptible to damage e.g. by an extrapped stone, and may wear less with some materials to be pelletised. <IMAGE>

Abstract: A device for generating position signals in dependence upon the relative position of two machine parts which are linearly displaceable relative to one another has an information carrier (16) supported on one machine part such as the carriage (10) of a machine tool. This information carrier (16) comprises a plate (18) of plastics material which extends in the direction of displacement of the carriage (10). A metallic layer (20) extends over the whole surface of the plate (18) and a number of information tracks (1-4) extend along the layer (20). At least one strip (22<1>, 24<2> 26<3>, 28<3>, 30<4>) of metal foil is aligned along each information track such that each track has at least two areas having differing electrical conductivity and/or cross-section. A multi-limit switch (12) having an inductive proximity switch (40<1>-40<4>) associated with each track (1-4) is mounted on a stationary machine part (14). As the carriage (10) moves relative to the machine part (14) the proximity switches (40<1>-40<4>) scan the respective tracks (1-4) and generate position signals. <IMAGE>

Patent GB-2073544-A (GB)
Title: Electro-acoustic transducer
IPC: G04C21/02
Filed: 1981-03-19
Abstract: The transducer is particularly useful in a watch. The emission of acoustic waves is caused by vibration of a thin diaphragm 8 occupying virtually the whole of the bottom of the watch case 1. The electromagnetic diaphragm excitation device 10 is disposed at an off-centre position. This not only makes it possible to operate with a small air gap, providing good electromagnetic coupling and therefore a good output, but it also makes it possible to produce a large vibration amplitude at the centre of the diaphragm 8 and therefore a high level of sound intensity for an entirely reasonable rate of consumption. The diaphragm 8 is fixed in a ring 6 which carries the excitation device 10 and which is fixed to the support frame structure 5 of the watch. This modular construction facilitates fitting and interchangeability of the electro-acoustic transducer. <IMAGE>
