Filed: 1972-04-28
Abstract: 1368339 Heat exchangers APV CO Ltd 13 April 1973 [28 April 1972] 19922/72 Heading F4S [Also in Division F1] In a heat exchanger a flow space for one of the fluids (e.g. blood) is formed between two coaxial conical surfaces at least one of which is a heat exchange surface and one of which may be moved axially to vary the thickness of the flow space. The said movement may be oscillatory whereby the relative movement of the surfaces provides a pumping action for said fluid. The cone angles of the respective surfaces may differ from each other. As shown in Fig. 1 the outer cone 1 is fixed and the inner cone 2 is movable axially by means of a rod 7. The flow space between the cones is supplied through an inlet 5 and the fluid discharges at 6. A jacket 3 for another heat exchange fluid is formed around the cone 1, and a further flow space for said fluid is defined within the cone 2 by a block 4, this flow space having an inlet 8 and an outlet 9. In Fig. 2 where the cone angles differ and only a jacket 3 is provided, the inner cone 2 has a compressible layer 11 of rubber or plastics material thereon said to prevent galling (defined in the Specification).  In further arrangements (Figs. 3, 4) two of the cone pairs are interconnected respectively base to base. The inner cone memers (21) are oscillated axially to provide a pumping action on the fluid passing between the cones. The pumping effects suction of the fluid into the flow space of one cone pair and discharge of fluid from the flow space of the other cone pair. The fluid passes from one flow space to the other via a oneway seal (22, Fig. 3) or non return valves (43, Fig. 4).

Abstract: 1,082,936. Electromagnetic relays. STANDARD TELEPHONES & CABLES Ltd. May 14, 1965 [May 21, 1964], No. 20428/65. Heading H2B. In an electromagnetic relay having a sealed magnetic reed contact unit 3 between the polepieces 2 of a remanent magnetic core 1 carrying two windings 6 and 8 which produce transverse fluxes in the core, the contact unit is closed by winding 6 and opened by energizing the transverse winding 8 and an auxiliary winding 7 which acts in opposition to winding 6. This enables the flux state induced by winding 6 to be cancelled completely with a lower current in winding 8. In an alternative arrangement (Fig. 4, not shown), the transverse windings are connected together at one end and to the respective fixed contacts of a change-over switch of the supply at the other end. The two windings are tapped, each tap being connected to one fixed contact of a second change-over switch of the supply. With the change-over switches in one position the whole of one of the windings is energized and the tapped part of the other winding. Reversal of both changeover switches energizes the whole of the said other winding in opposition to its previous energization and the tapped part of the said one winding in opposition to its previous energization. In Fig. 5, not shown, the tapped windings are connected at their tapping points to a common supply terminal and the other ends of the transverse windings are connected to the respective fixed contacts of a changeover switch connected to the other supply terminal. Resistors are connected in series with the tapped section of each winding, and the combination of resistor and tapped section is shunted across the main part of the winding transverse thereto. Thus successive energizations produce the same results as before. The invention is applicable to the relay described in Specification 1,056,081 (Figs. 6 and 7).
