Title: Heat pump
IPC: F24F1/0325
Filed: 1965-04-21
Abstract: 1,110,721. Refrigerating; rotary heat exchangers. N. LAING. 21 April, 1965, No. 2649/65. Headings F4H and F4S. A heat pump comprises first and second heat exchangers and a refrigerant pump mounted on a common axis for rotation as a single unit, the heat exchangers being formed aerodynamically to act as impellers promoting a flow of fluid over their heat exchange surfaces. As shown in Fig. 5, the heat exchangers 56, 57 are mounted end-to-end and comprise hollow blades 131 of aerofoil crosssection having annular fins 66. Refrigerant from a compressor 60 passes through the blades of exchanger 56 in which it is condensed, and is then supplied through one or more capillary tubes 69 to alternate blades of exchanger 57, the evaporator. The refrigerant returns through the remaining blades of the exchanger to a header 62 and thence through an axial duct 61 to the compressor. The latter, together with its motor 58, 59 is mounted in a casing 55 which, together with exchangers 56, 57 is rotated by a further motor 53, 53A. The complete unit is mounted in a fixed frame 50. The frame may be positioned in an aperture in the external wall of a room (Figs. 6 and 7, not shown) and the heat exchangers each provided with a rotatable shroud so that they act as cross-ftow impellers. Each shroud may be placed in four main positions in which: only room air circulates over the associated heat exchanger; only external air circulates thereover; external air is supplied to the room over the heat exchanger, and room air is extracted over the heat exchanger. In the embodiment of Fig. 8, a casing 210 located in the wall 94 of a refrigerator or cold-store supports coaxial spindles 225, 226 which carry the rotary heat exchanger 90, 91 having internally partitioned aerofoil blades. Spindle 226 carries a rotor 220 which is driven by a stator 221 and rotates a casing 224 together with the exchangers. Casing 224 is surrounded by a stator 223 and encloses a rotor 222 in the interior of which is provided a refrigerant compressor of the rotary pistonsliding vane type (Fig. 9, not shown). Two forms of heat exchanger for use in the heat pump are described with reference to Figs. 1 and 3 (not shown). In the former, the aerofoil blades are interconnected by annular elements having corrugated walls, while in the latter the heat-exchanger is formed from a single helically wound strip provided with hollow stubs of aerofoil section. The corresponding stubs of adjacent turns of the helix are connected to form the aerofoil blades.

Abstract: 991, 795. Microwave analyzing apparatus. BELOIT IRON WORKS. Jan. 24, 1962 [Jan. 24, 1961], No. 2676/62. Heading G1N. An arrangement for determining the moisture content or content of another substance in a solid granular or fluid material comprises a surface wave guide over which microwave energy is transmitted and into the microwave field of which the material is introduced, the frequency preferably being one at which particle resonance occurs in the substance being detected. A sword type arrangement, Fig. 1 for insertion in a material such as cereals and other foodstuffs, or between the sheets of a stack of sheets of material such as hardboard or paper, comprises a tunnel diode microwave generator, or a reflex velocity modulated tube such as klystron, the resonant cavity size of which may be varied mechanically by for example a solenoid or the frequency of which may be varied by varying the power supply. Energy is coupled to a hollow, surface-waveguide 53, which in order to limit the field of energy may comprise a less efficient conductor such as stainless steel or aluminium, the coupling means being a rectangular waveguide 36 and a coaxial launching arrangement 30 including a conductive horn 32 and a central inner member 34. The probe is terminated by a lossy dielectric such as loaded polyethylene in order to absorb the energy and prevent reflection, and microwave detectors 22, 64 which may be crystals or bolometers are mounted at the respective ends. An alternative position 44 for the detector at the launching end is shown, and the use of a graphite coating at the end of line portion 61 as an energy absorbing arrangement is referred to. The signals from the two detectors which may be of low frequency or direct current are applied to a ratio meter 23 which includes an adjustable attenuator whereby the two signals may be balanced, the setting of the attenuator being a measure of the moisture content. Alternative cross-sections with dimensions in wavelengths are described with reference to Figs. 2-5 (not shown), and an arrangement for association with a paper machine in which a surface is contoured to conform with the surface of the running paper and wherein the terminal end of the probe is identical with the launching end is described with reference to Fig. 6 (not shown), the detector being matched to the line to act also as the absorbing termination. The comparator may compare energy content or phase of the microwaves and the apparatus may be used to detect deuterium oxide or deuterium hydroxide in water or deuterium oxide in deuterium hydroxide.

Lanthanum barium manganite. lanthanum strontium manganite with the addition of either lanthanum aluminite or lanthanum ferrite, lanthanum strontium barium manganite, and lanthanum lead manganite are described as made in a similar manner. Other substances which may be incorporated in the core material are the manganites of yttrium. praseodymium, neodymium, calcium and cadmium. Reference is also made to the addition of ferrites, chromites, titanates and aluminates, and to the replacement of part of the manganese by aluminium, chromium, titanium, iron, cobalt or nickel.

The crosslinked copolymers may be formed by polymerizing styrene and acrylonitrile in the presence of divinylbenzene or by treating a styrene/ acrylonitrile copolymer with the diglycidyl ether of bisphenol A and the expanded particles are made from expandable particles of the crosslinked copolymer containing a volatile fluid foaming agent, e.g. dichlorodifluoromethane, trichlorofluoromethane and/or trifluorotrichloroethane. The foam is made by mixing a selfreacting exothermic open cell foam forming composition, e.g. a polyurethane forming composition comprising a polypropylene oxide triol, water, a silicone surfactant and toluene diisocyanate with optionally trichlorofluoromethane, with the above expandable particles which form a closed cell foam, and casting or moulding the mixture into a desired shape while the expandable particles foam.

Leader gear; signalling to or from aircraft; undesired signals, eliminating.-Relates to methods of steering ships, aircraft, and the like bv means oi the fields of force extending from one or more guiding cables fed with alternating current as described in Specification 167,184. The invention is directed to removing the disturbing effects upon the detecting-coils of parasitic fields of force due to electromagnetic radiation and low-frequency induction effects arising from magnetos &c., or from fields of force due to casual high-frequency currents induced in the circuits of the installation, particularly in connection with aircraft. These disturbing effects are avoided (a) by shielding each magneto, (b) by balancing the short-wave radiations or induced fields by means of compensating coils which are arranged in opposition so that any energy picked up is nullified, (c) by breaking the receiving circuit in synchronism with the sparking frequency of the disturbing magneto so as to cut out the electromagnetic effects of the spark. In addition the planes of the main detecting- coils are as far as possible arranged parallel with or tangential to the parasitic lines of force. As shown in Fig. 6 the main search coil 1 responding to the alternating field from the guiding cable (indicated by the horizontal arrows) is in series with a reversed coil 2 so located and adjusted that the combined effects of the parasitic fields (indicated by the curved lines) are neutralized in the receiving instrument 16. Fig. 10 shows a switching arrangement for throwing a large condenser 14 across the terminals of the receiving amplifier 16 in synchrony with the sparking period of the magneto 8, so as to eliminate reception in the telephones 15 during the actual moment of sparking. This is effected by means of a rotary switch 9 which alternately opens and closes the circuit containing the condenser 14, which is shunted across the telephones as shown.
