Title: Improvements in or relating to protective clothing and the like
IPC: A41D19/00
Filed: 1959-08-06
Abstract: Protective clothing is made by applying to one side of a fabric a coating of a substance which can be converted by gelling, curing or the like to a durable solid, the nature of the substance and its manner of application being such that there is no penetration through the fabric, thereafter applying to the said substance a further substance of such composition and in such a manner that it modified the composition and rheological properties of at least the outer layers of the first substance so that more of it can be drained off than would otherwise be possible, draining by the desired amount, and converting the coating to a solid without penetration through the fabric. The fabric may be for example a pre-shaped glove lining and be supported on a former, and the substances may be applied by dipping. The first substance may be a suitably plasticized polymer composition, and the further substance may contain the same composition together with more plasticizer, or consist wholly of a plasticizer or solvent it may contain grains of solid material, to provide a rough coating to the finished article. In tests, knitted glove liners are mounted on formers and coated by dipping with a liquid mix containing polyvinyl chloride powder plasticizers, stabilizers and pigment, drained, and dipped in the same mix with added plasticizer, with or without additions of "Geon" (Registered Trade Mark) 202 polymer or silica sand, or in plasticizer alone, or in toluene, again drained and cured. In further tests the liners are first dipped in a mix containing polyvinyl acetate or polyvinyl alcohol, glycerine and water, and then in hot water. Specifications 624,795 and 880,165 are referred to.

Title: Electrical connector assembly and mounting means therefor
IPC: H01R13/14
Filed: 1967-05-16
Abstract: An insulating terminal block 1 designed to be mounted in a support rail has a pair of resilient legs 7, 8, formed with detents 9, 10, the legs extending beyond the detents and being joined by a strut 12 at their ends remote from the block. The block, which is made of nylon, is retained in position on the rail by the rail edges 4, 6, which clip between the detents, 9, 10 and shoulders 3, 5 respectively. Stabilization is provided by the pressure of strut 12 against the base of the channel forming the rail due to the elasticity of the legs 7 and 8 which are deformed when the block is in position on the rail. The shoulders 3 and 5 slope away from the rail to permit the insertion of a lever to remove the block from the rail.

Patent ES-346377-A1 (ES)
Title: Fuel injection system for internal combustion engines
IPC: F02D41/30
Filed: 1967-10-24
Abstract: A pressure transducer 22, Fig. 2, associated with a control system (18, Fig. 1, not shown) for an I.C. engine is connected to the inlet manifold through a throttling orifice (46, Fig. 3, not shown) in a closure valve 43 at the end of a pipe 23 connected to the manifold. The orifice prevents fluctuations in manifold pressure due to operation of the engine inlet valves, &c., from reaching the transducer. A large increase in inlet pressure due to an opening of the butterfly valve (29) for a required acceleration, is permitted to reach the transducer by the valve 43 being opened against the pressure of a spring (47) by the said increase in pressure. A similar arrangement may be used to allow for a large decrease in pressure due to deceleration. The pressure bellows 36, 37 operate a moving core transducer, 38, 39, 42. The pressure transducer may be, alternatively a pressure responsive resistor, capacitor or transformer.
Patent ES-348164-A1 (ES)
Title: Improvements in and relating to thermostatic valves
IPC: F16K31/68
Filed: 1967-12-12
Abstract: A valve, usable in a vehicle air conditioning apparatus in which it is interposed in the hot water circuit of a radiator, comprises a water inlet 12, a water outlet 13 and a seat 14 formed therebetween, the seat being engageable by a diaphragm 15 which is clamped at its periphery and is movable in relation to the seat either by a mechanical actuator or by a fluid thermosensitive element. The mechanical actuator consists of a three-part piston 45, 46, 47 which is bodily movable within the valve casing 16 as a result of movement of a cam 28 which engages a follower 41 rotatably held in the piston upper part 45. The thermosensitive element comprises a bulb 30, which is normally disposed in the current of air immediately downstream of the radiator, and which communicates with the upper side of a diaphragm 50 clamped at its periphery between the piston parts 46, 47, the underside of the diaphragm engaging a rod 29 slidable within the piston lower part 47. Movement of the rod is transmitted to the diaphragm 15 by two springs 31, 32 of which the former engages a reinforcing socket 25 which is embedded in the diaphragm 15 and through which the rod slidably passes. In operation, with the mechanical actuator, and hence the piston, in the position shown, expansion of fluid within the thermosensitive element results in diaphragm 50, and hence rod 29 and diaphragm 15, moving downwardly towards the seat 14, such movement resulting in a partial closure of the flow passage 11 (Fig. 3, not shown). Upon the actuator, and hence the piston, being moved to its lowermost position (Fig. 4, not shown), the flow passage becomes fully closed even in the absence of fluid expansion in the thermal element. In the event of such expansion subsequently occurring, then it is accommodated by downward movement of the rod 29 into a chamber 24 defined by the central portion of the daphragm 15 (Fig. 5, not shown), such movement of the rod not affecting the state of the valve. The mechanical actuator may attain positions intermediate to those described, but in all cases the thermosensitive element moves with the piston by virtue of the fact that it is welded to it at 54 and its capillary tube 52 passes through a longitudinal slot 38 formed in the valve casing 16.
Patent ES-348654-A1 (ES)
Title: Self-cancelling switches
IPC: H01H37/60
Filed: 1967-12-12
Abstract: A thermally operable self-cancelling switch includes a plurality of bimetallic elements heated sequentially to determine the overall operating period of the switch. Operating member 15 is biased to the open position shown in Fig. 1, by spring 26 and carries two bimetal arms 28, 29 formed with latches at their lower ends. Arms 28, 29 are in electrical contact with spring 26 through rivet 27 mounting spring 26 and arms 28, 29. Fined contact 21 is formed with two catches 22, 23 on its upper surface. To close the contacts, member 15 is moved clockwise so that the latch on arm 29 latches behind catch 22. The circuit is then completed through fixed contact 19, spring 26, rivet 27, bimetal arm 29 and fixed contact 21. As the current flows, bimetal 29 heats up and bends to one side freeing itself from catch 22 so that spring 26 urges member 15 towards the open position but before the movement is completed, the latch on bimetal 28 engages catch 23 so that the circuit is again completed between the fixed contacts through bimetal 28. Bimetal 28 heats up and bends to one side freeing itself from catch 23 so that spring 26 completes the movement of member 15 to the open position. When the switch is in either of the contacts closed position, the switch can be opened manually by depressing member 15 against the pressure of two springs 18 which support the bearing posts 16 of member 15 to move the latches on bimetal arm 28, 29 below the catches 22, 23 to free bimetal arms 28, 29 and allow spring 26 to pivot member 15 to the open position. In a modification in place of springs 18, bearing posts 16 are supported by a plate hinged at one end and supported by a spring at the other end.
