A refrigeration system of the flooded-coil type includes two vessels 15, 16 one of which is connected to receive and accumulate liquid refrigerant from the evaporator coils 18 while the other is connected to supply liquid refrigerant to the evaporator, and control means for periodically reversing the functions of the vessels. As shown, liquid refrigerant from the condenser 12 passes through a valve 13 and one of two solenoid valves 20, 21 into one of the vessels 15, 16. From that vessel, the refrigerant passes through a check-valve 29 or 30 and a fixed flow valve 17 to coils 18, and mixed refrigerant liquid and vapour from the coils passes to the other vessel via a check-valve 27 or 28. Vapour from the other vessel returns to the compressor 10 via a solenoid valve 22 or 23. The valves are controlled, either by a timer (Fig. 2, not shown) or by floats responsive to the liquid level in one of the vessels (Fig. 3, not shown) so that valves 21 and 22 are open while valves 20 and 23 are closed and vice versa. The refrigerant supplied to vessel 15 or 16 contains flash gas which is returned to the compressor via a valve 24 or 25, said valves being connected in parallel with valves 22 and 23, respectively, and being adjusted so as to maintain a pressure in vessels 15, 16 sufficient to ensure the supply of liquid to coils 18. In a second embodiment (Fig. 4, not shown) the major portion of the liquid from the condenser is supplied to the vessel which is receiving liquid from the evaporator, and a minor portion of the condensate is passed through a pressure reducing valve to the other vessel to discharge liquid refrigerant therefrom. In a third embodiment (Fig. 5, not shown) liquid from the vessels is supplied to the evaporator via a receiver which receives all but a minor portion of the refrigerant from the condenser, the remaining portion being used to pressurize the vessels as in the previous embodiment. Alternatively, the pressurizing refrigerant may be derived from a point upstream of the condenser.

Abstract: 933,354. Pressing chipboard. H. VAN HUELLEN, and A. VAN HUELLEN, [trading as NIEDERRHEINISCHE MASCHINENFABRIK BECKER & VAN HUELLEN]. Dec. 24, 1960, No. 44381/60. Class 87(2). In a machine for making chipboard, comprising an intermittently closing press 1, chipstock is spread evenly on an intermittently moving conveyer belt 2 by a charging device 6 which is movable with an adjustable but constant speed relative to the conveyer in a direction away from the press 1, this speed being less than the speed of the conveyer towards the press the distance moved by the conveyer during the time the press is open being equal to the distance moved by the device 6 relative to the conveyer during a cycle of the press. A chain 12 is fitted on each side of the belt 2 and is arranged to be driven at the same speed as the belt, the belt and chains being held at rest while the press is operated. A gear wheel 13 driven from a motor 14 engages with each chain 12 and drives the charging device 6 in the direction of the arrow A, while the belt and chains are stationary, but with a speed which is less than that of the belt 2 towards the press when the belt is moving. The charging device thus moves with a constant speed relative to the belt, but actually moves in the direction of the arrow A while the press is closed, and is carried in the direction of the arrow B while the press is open and a new charge is being supplied to it. The trailing edges 9a, 10a of press members 9, 10 are cooled so that chipstock therebetween is only precompressed and not cured, and after pressing the chipboard is fed to a trimming device 8. The chains 12 may be dispensed with if the gear wheels 13 are replaced by friction wheels acting directly on the belt 2.

Abstract: 1332352 Colour coded holograms R C A CORPORATION 23 Sept 1970 [30 Sept 1969 28 Nov 1969] 45308/70 Heading G2J [Also in Division H4] To form a colour encoded hologram information representative of the colour of a scene is encoded into mono-chromatic intensity variations which are then illuminated by a coherent monochromatic light beam to form on a record medium a colour encoded Fraunhofer hologram. In one embodiment a sequence of transparencies 34 Fig.3 are illuminated by a light source 31. A striped spatial colour coding filter assembly 36 is disposed adjacent each transparency as it is illuminated, the image produced being focused on to a black and white film. The film produced may be a strip film 60 Fig.4. This film is then illuminated by a beam 46' of coherent monochromatic light which has passed through a diffuser or two-dimensional phase grating 59 to add redundant information. The holograms are recorded on a rotating disc 64 in a spiral formation. To get synchronized exposure disc 64, film 60 and a shutter 43 are all operated by a motor 66. In another embodiment Fig. 5 the mono-chromatic light beam 46 is divided into three sub-beams each of which illuminates a colour separation negative 73, 79, 82 representing the colours red, blue and green respectively. Negatives 73, 79 have different gratings 74, 80 associated therewith. All three modulated sub-beams are recombined and the combined beam interferes with the reference beam 47' to form the colour encoded hologram on disc 64. The hologram is a phase hologram and may be recorded on any photosensitive, thermoplastic, or photo-resist material. Preferably the hologram is then copied and copies are used in reproducing coloured images. A further embodiment discloses the formation of the colour encoded scene prior to formation of the hologram. The scene may emanate from video signals and consequently a brightness signal is contained within a first range of frequencies and the colour signals which are separated from the combined signal are contained within a second range of frequencies. The colour encoded scene is recorded on black and white film which is used to form the Fraunhofer hologram. For reproduction a coherent beam and lens may form a colour encoded image on a pick-up tube (91), Fig.7 (not shown) the output signals from which are separated into three ranges of frequencies corresponding to a luminance Y, a blue representative signal B-Y and a red representative signal R-Y respectively which are then applied to corresponding video amplifiers in a colour television receiver.
