The method makes possible operation at higher temperatures with a given refrigerant fluid. LMTD is defined with respect to the temperature differences between the refrigerant fluid and the air at the air inlet and air outlet to the condenser. In one embodiment, Fig. 1, (not shown), the evaporator and the condenser of the heat pump arrangement are in a common casing and the air is circulated through both. Some of the air may bypass the evaporator. In another embodiment, Fig. 3 (not shown), ambient air is used to heat the refrigerant fluid in the evaporator, which is outside the casing.

Abstract: 1,236,225. Magnetic holograms. RCA CORPORATION. 29 April, 1968 [12 May, 1967], No. 49218/70. Divided out of 1,236.224. Heading H3B. A hologram is in the form of a magnetic film, the magnetization of which varies from point to point in accordance with the hologram pattern. A quartz wedge beam splitter 208 splits the pulsed laser beam 202 into a reference beam 204, 212 and a second beam 206 which is spatially modulated by the scene on transparency 220 or a three dimensional object to be recorded on magnetic film 214. The two beams 224 and 212 are projected on to the same area of member 214 and produce an interference pattern corresponding to the hologram pattern. The intensity of the pulsed laser is insufficient to cause evaporation of the magnetic film 214, but sufficient to cause relative loss of magnetization of the material from point to point by heating in accordance with the relative intensity of the light reaching that point. Alternatively, the intensity of the laser may be such as to cause evaporation of the magnetic film so that a pattern of the hologram is visibly engraved in the film. The magnetic film is magnetized before or after application of the pulse, the magnetic field varying in accordance with the thickness of the thin film so that the engraved hologram pattern is manifested in magnetic form.

Abstract: 1,096,116. Roughening treatment for plastics film. KALLE A.G. Dec. 16, 1964 [Dec. 17, 1963], No. 51197/64. Heading B5B. One side of a relatively non-slip plastics film, which film preferably is in continuous web form, is subjected to a mechanical roughening treatment by sliding contact with a roughening element or elements. Such treatment produces a roughened effect which is so fine as to be substantially invisible to the naked eye but to be visible under the microscope; the slip properties of the film are improved in that the treated side of the film is of increased slip, i.e. has a reduced coefficient of friction. The roughening preferably is in two directions obliquely to the film so that a diamond pattern is produced thereon. The roughening treatment may be effected by one or more brushes or by a roller or rollers provided with bristles or fibres; the brush material preferably is mounted on a roller which is rotated at the point of contact with the film in a direction opposite to the direction of movement of a moving web of the film. The fibres or bristles advantageously are of soft natural or synthetic material, for example lambskin, wool, cotton or polyethylene. Alternatively, cloth, suede or skins, advantageously mounted on rollers, may effect the roughening treatment. The plastics film, which preferably is transparent, may be made from polyolefins, for example polyethylene or polypropylene ; halogenated polyolefins, for example polyvinyl chloride; and polyesters, especially those produced by condensing benzenedicarboxylic acids with aliphatic diols, for example polyethylene terephthalate. Reference has been directed by the Comptroller to Specification 1,035,308.

Abstract: 1,067,960. Bi-stable circuits. LANDIS & GYR A.G. Dec. 18, 1964 [Dec. 20, 1963], No. 51616/64. Heading H3T. In a transistor bi-stable circuit, having feedback between an output stage 3 and an input stage 1, the control current to the input stage is amplified by a transistor pre-input stage 18, complementary to that of the input stage 1. The input stage and the pre-input stage 18 each consist of the same number of transistors which may be single transistors or composite types, as shown. With no input signal from a source connected across terminals 16, 17, the transistor pre-input stage 18 and input stage 1 are conducting and output stage 3 is biased off by battery 8. If terminal 16 is made positive with respect to 17, then the base-emitter current of the pre-input stage 18 increases and input stage 1 becomes less conductive, which raises the potential of its collector so that output stage 3 conducts. Feedback via resistor 10 further decreases the conduction of stage 1 and increases the conduction of stage 3. The circuit returns to its original state when the input voltage at 16, 17 is reduced to a certain level. The transistors may be of the junction or field effect types and at least one of the transistors in the pre-input stage 18 or the input stage 1 may be a photo-transistor. Applications of the circuit are: two-point regulator, threshold value indicator, photo-electric switching, and in fault current protective switches.

In an air conditioning system for railway vehicles in. which cooling air is supplied to the compartment and which is adequate to cool a full compartment, the cooling capacity is reduced dependent upon the temperature in the compartment when there are fewer passengers. The cooling is reduced by regulating the heat supply over at least part of the range and by regulating the basic amount of cooling air supplied over at least part of the range.
