Title: Air conditioning layout for buildings - uses height difference between supply and dispenser, small and large bore lines heat exchangers and vapour pump
Inventor: PARKER SIDNEY ARCH
IPC: F24F5/00
Filed: 1976-03-10
Abstract: Air conditioning plant for buildings, hotels etc., utilises the height difference in natural conditions as well as naturally occurring temperatures. It consists of heat dispenser unit (14) at the high elevation and a heat supplier (18) in the valley, with expander for the coolant at this level and small bore lines (22) to link the supply to the high elevation dispenser. An insulated larger diameter line (30) runs between the condenser (26) and the high elevation consumer building (12). Thus the height difference pressurises the coolant in the small bore line. A load regulator (36) controls the fluid circuit and the coolant is expanded in the small bore line, evaporated and cooled so as to accept heat from the supply and pass on to the dispensing point. A vapour pump feeds the evaporated fluid back to the dispenser, and the supply should be by heat exchanger (26). The small bore line can also be lagged.

Title: Grain cleaner for combine harvesters - has chaff suction intake over top sieve to form suction zone parallel to sieve across flow
IPC: A01F12/44
Filed: 1976-05-11
Abstract: The grain cleaner for a combine harvester comprises a stack of sieves which are blown from below at an angle to move chaff and grain together and allow grain to fall through the sieves. Above the topmost grain sieve (11), is a chaff suction intake (17) connected to a suction blower. The suction entry (19) facing the sieve forms a suction zone which lies parallel to the sieve and at right angles to the chaff flow. The suction intake is an elongated trapezoidal structure whose floor (20), and top (18) diverge in the chaff movement towards the rear. The top projects and passes around the floor at the front to from the suction entry slit. (19). A slide (26) lying flat on the floor (20) of the suction intake projects on the slit side and the free rim (26a) of the slide is bent inward.

Title: Heat pump for space heating applications - has absorption type circuits in parallel with compressor type circuit
Inventor: ALBERS HERMANN
IPC: F25B30/00
Filed: 1976-06-02
Abstract: A heat pump operates between an evaporator and a condenser through which appropriate liquids flow and transfer heat to and from a refrigerant. The refrigerant passes through coils within the evaporator and condenser. One refrigerant circuit is taken through a compressor and an expansion valve and operates on a compression cycle. Further coils are closely wrapped round the coils of this circuit and connected to form closed circuits in parallel with the compressor circuit. As soon as the compressor circuit establishes a temp. difference between the evaporator and condenser the parallel circuits start to operate on the absorption cycle and thereby increase the overall coefficient of performance. The entire heat pump is controlled by the compressor.

Title: Guidance control for linear induction hovertrain - with guidance coils and drive coils in separately sprung subframe
Inventor: MILLER LUITPOLD
IPC: B61B13/08
Filed: 1976-06-12
