Abstract: 1, 247, 371. Testing elastomeric material. B. F. GOODRICH Co. Sept. 23, 1968 [Sept. 25, 1967], No.45133/68. Heading G1S. A sample 84 of vulcanizable elastomeric material which is to be tested during curing is clamped between a platen 8, and a platen 9 which may be raised by a pressure piston 14, both of which platens are heated to cure the sample by coils 72, 73 controlled by a unit 71. A pressure piston 17 is controlled by a solenoid operated fluid piston valve 22 connecting supply lines 21, 30 and 31 and exhaust lines 30, 31, 33 and 34, and as the piston 17 moves upwardly it also takes upwardly the cylinder 15, the bracket 16, housings 50, 51 defining a chamber 52 supplied with air under pressure from pipe 75 and lower platen 9 to compress the sample 84. Air-pressure is also supplied to cylinder 15 via a conduit 77 to maintain a predetermined pressure between 8 and 9 whilst conduit 75 maintains a pressure in the chamber 52. A motor 48 is then energized which rotatably oscillates the upper platen 8 through gearing 47, 45, 42 and 41, and a pick-up 56 which comprises a resistance wire strain gauge bonded to the shaft 40 is connected into a bridge circuit and with a recorder 57 which traces the torque on the sample as a graph on a chart 86. The oscillations can be varied by altering the linkage 42, 41 Fig. 2 (not shown), and during the action a load cell 81 also provides an output signal indicating thrust during curing of the sample which is similarly recorded. In a modification, Fig. 3, the upper plate 90 is oscillated as before and its torque measured, or the angle of rotation of the shaft instead of its torque may be measured by a guage 93, the torque being measured by a cell 118 and the load by a cell 100. The lower platen 95 is similarly connected and moved as for the previous plate 9. A housing 107 is recessed at its top to receive the sample 115 and a special sealing arrangement is provided between the heated platens 90 and 95 and housing 107. In a further modification, Fig. 6 (not shown), the lower plate is pin and slot connected to the vertically movable lower housing portion to prevent relative rotation, and a load cell is sandwiched between.

Title: Cryosurgical instruments
IPC: F25B9/02
Filed: 1972-09-29
Abstract: 1339218 Cryosurgical instruments R M WALLACH 29 Sept 1972 [6 Oct 1971] 45177/ 72 Heading A5R A cryosurgical instrument comprises a probe 14 having an internal expansion chamber 30 to which refrigerant is supplied through a restricted orifice 66 for providing a Joule-Thomson expansion of the refrigerant in the chamber, effluent gas being conveyed from the chamber along a path including a flow control valve 42 for selectively opening and closing the path. Saturated gas, e.g. carbon dioxide or nitrous oxide, is fed from cylinder 22 to expansion chamber 30 through a conduit 51 coaxial with a tubular body 13, the space therebetween providing a return path 67 for effluent gas. The path 67 communicates with valve 42 which has a flow passage 94, 92, 96 therethrough which is controlled by a valve element 100 biassed by spring 102 so that a segment 113 of the valve element seats against the inlet to bore 96. A lever 12 is pivotally connected to the valve element so that when lever 12 is moved anticlockwise valve element 100 moves against the spring to open the bore 96 and hence the passage through the valve to atmosphere at 44. A sintered disc 90 reduces the noise of escaping gas. To enable the flow passage to be kept open, the upper edge of lever 12 is bevelled and its connection to the valve element is such that it can be rotated clockwise to abut housing 106 thereby biassing the valve to the open position. The spring 102 is such that if the pressure within the instrument exceeds a predetermined amount the pressure acting through bore 94 on a shoulder 120 of the valve element will move the valve element away from the bore 96. A valve 20 is provided to interrupt the supply of refrigerant. In a valve modification, the segment 113 of the valve element is tapered and means are provided for presetting the distance by which it can move away from bore 96 thereby varying the size of the inlet to bore 96 to obtain a predetermined refrigerant flow rate and hence predetermined temperature of the probe.

Abstract: 1344144 Coils for dynamo electric machines JECO CO Ltd 11 Oct 1971 [12 Oct 1970] 47200/71 Heading H2A A core-less rotor for a dynamo-electric machine comprises arrays of conductors on the inner and outer surfaces of a hollow cylindrical insulating support, the conductors being inclined in opposite directions to the rotor axis on the two surfaces and being electrically interconnected at the ends of the support. In the motor shown, part of the rotor periphery forms a commutator engaged by brushes 19, the rotor being mounted between a ferromagnetic casing 11 and a stator permanent magnet 12. The rotor is mounted on an insulating support 17 secured to the rotor shaft 15. In a modification, Fig. 1B (not shown), a separate commutator is formed on the support 17. The rotor may be made using printed circuit assemblies or a slitted copper sheet adhered to or embedded in a sheet of plastics material. In one method of assembly, a sheet bearing parallel conductors is cut to form a parallelogram having two opposed sides parallel to the conductors. This is folded over, with the conductors on the outside, to form a trapezium which is then rolled up to form a cylinder. The conductor ends may be electrically connected by dipping in a solder bath to form one complete coil. In another method, the parallelogram is folded over several times to form a multiple-ply trapezium before the latter is rolled up to form a cylinder. This provides a multi-pole rotor. In a further method, parallelograms of different length are superimposed on one another and then rolled up with the shorter (or shortest) one on the inside. In this method, soldering is required at both ends of the rotor.
