A laundry plant comprises at least one group of at least two electric washing machines, the washing machines in the or each group being interconnected by connecting liquid pipes each having a drain conduit, a control device controlling electric circuits for the machines so that each washing machine in its group fulfils a complete washing cycle; in said control device driving means driving removable and adjustable elements each of which coacts with at least one contact device controlling one of said electric circuits, the arrangement being such that the washing cycles of the washing machines in the or each group are out of phase. The control device may comprise a driving means, one complete revolution of which controls a complete cycle in each machine, the operations in each machine being out of phase by an equal interval of time, or two groups of machines may be controlled by two co-ordinated synchronized control devices so that the two groups are mutually out of phase. The groups of machines may be supplied from a common liquid reservoir. As shown, Groups I and II of machines A 1 , A 2  and A 3  have controllers B which are synchronized. Liquid may be transferred from one machine to the other by pipes 1, fresh liquid may be supplied directly to any machine, and waste liquid removed through drain conduits 2.

Abstract: 615,402. Electric filters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 8, 1947, No. 21986. Convention date, Oct. 7, 1938. [Class 40 (viii)] [Also in Group XL (c)] A radio receiver for the reception of two carrier frequencies in adjacent channels, such as for television and associated sound, comprises an aerial supplying an input transformer 10, 12 tuned by a condenser 14 and coupled to a coil 16 having a resistance 18 for extending the band width so as to include both frequencies. An oscillator 22 has a tuned circuit 24, 26 which is coupled to coil 16 so that the oscillator frequency and both carrier frequencies are applied to the control grid of a frequency changer 20, the output of which thus includes both the sound and the picture intermediate frequencies. The intermediate frequency transformer 28, 44 is tuned by adjustable magnetic cores to the picture intermediate frequency which s then amplified by valve 40 and passes to the subsequent stages. A condenser 54 and inductance 56 are connected between the control grid of 40 and ground to form a circuit which is series resonant to the sound intermediate frequency so that at this frequency coil 44 is effectively short-circuited and condenser 42 is effectively in parallel with coil 28, the lower end of which is grounded through byepass condenser 34. Condenser 42 is adjusted to cause coil 28 to resonate at tho sound intermediate frequency and the oscillations are applied to a sound intermediate frequency amplifier 60 and to subsequent stages.

A rotary-piston diesel engine as described in Specification 1,107,081 in which each working chamber includes a cylindrical combustion chamber 9, Fig. 1, extending the full axial extent of the piston 3, an air inlet valve 18, Fig. 2, and an exhaust valve 19, to create turbulence in the working chambers by the movement of the centre of gravity of the chamber in its cyclic increase and decrease in volume, by the rotation of air in the combustion chamber and by the curved and tangential positioning of each inlet duct with respect to its working chamber includes a helicalcentrifugal turbo-supercharger 40 driven by a helical centripetal turbine 37 by the exhaust gases. Each combustion chamber 9 is connected by a lagged pipe 34 controlled by a blow-off valve 27 to drive the turbine 37 which in turn drives the rotor 40 of the supercharger 40. With five working chambers there are five pipes 34 equally spaced around the turbine and five pipes 42, leading one to each inlet duct. The engine includes a flywheel 15 and a counterweight 16 at either end of the engine shaft. The inlet, exhaust and blowoff valves are opened and closed in timed sequence by cams and linkage driven from the engine shaft. The inlet valve remains open from top dead centre with a conventional angular lag of from 30‹ to 60‹ beyond bottom dead centre, then closes and remains closed together with the exhaust and blowoff valves during compression and part of expansion until pressure has been reduced to 40 to 55 p.s. i. whence the blow-off valve 27 is opened to supply the turbine with exhaust gases. At substantially bottom dead centre the exhaust valve 19 also opens and for some time inlet and exhaust valves remain open with the exhaust valve closing just prior to top dead centre. Simultaneously with the opening of the exhaust and blow-off valves the inlet valve is partially opened to provide scavenging or alternatively a small scavenging valve may be provided which may also be utilized to cool the rotor at its hottest point.

Title: Process and means for defrosting absorption refrigerators
IPC: F25B47/02
Filed: 1960-06-27
Abstract: 931,965. Refrigerating. H. STIERLIN. June 27, 1960 [July 10, 1959], No. 22459/60. Class 29. In a process for defrosting absorption refrigerators, the refrigerant is withdrawn from the circulation system outside the solvent circulation system and is stored in a storage device forming a part of a separate circulation system, the storage device being automatically emptied periodically whenever a predetermined quantity of refrigerant has collected therein, the time taken to empty the storage device being very short in comparison with the time taken for the predetermined quantity of refrigerant to collect in the storage device, and the refrigerant withdrawn from the storage device is brought into heat-exchanging relation with the boiler whereby some heat content of the boiler is extracted therefrom in this very short time, the refrigerant heated thereby being supplied to the evaporation system to effect defrosting thereof. As shown in Fig. 1, refrigerant vapours collect and condense in a liquid storage device 5. The quantity of condensate rises in the device 5 until it is syphoned off down a pipe 7 into an evaporator 8. By heat exchange the refrigerant is vaporized extracting heat from the boiler system 1. The vapour flows through a pipe 9 to defrost the evaporator 3. Alternatively the element 5 can be connected inside the condenser 2. In a modification a capillary absorbent member draws liquid after the condenser 2 into a liquid storage device 5. As shown in Fig. 3, the evaporator chamber is replaced by a gas pump 12 which pumps a vapour liquid mixture for defrosting purposes into the evaporator 3. In a further modification liquid for defrosting may be extracted from the evaporator 3 so that the thawing period is automatically controlled by the degree of icing of the evaporator. As shown in Fig. 5, the storage element 5 is provided with a displaceable insulator 20 to regulate the condensation speed. The height of the syphon bend 6 may be adjustable.

Abstract: 460,666. Optical polarizing-apparatus. UNDERWOOD, L. R. May 28, 1935, No. 22716. Divided out of 457,443. [Class 97 (i)] [Also in Group XI] In a vehicle lamp, searchlight, or other lamp emitting a concentrated beam of light, substantially the whole of the light emitted by the lamp bulb and concentrated by the lamp reflector is plane polarized substantially horizontally. A self-contained fitting, attached to the front of the lamp casing, plane polarizes the light horizontally. The lamp and its front fitting may be constructed similarly to those described in Specification 457,443, the prisms of the front fitting running horizontally instead of at 45‹ to the horizontal. The front fitting may be rotatably adjustable. In another form, shown in Fig. 8, plates 13, 14 formed as a series of convex and concave cylindrical lenses respectively, together stratify the beam into a number of narrow parallel beams, each of which impinges on a slat 17 which is a polarizer composed of a pile of films. Between the slats 17 are parallel reflectors 18. The slats transmit beam components polarized in one plane, and reflect beam components polarized in planes at right-angles onto the reflectors 18, which reflect them forwardly. Mica strips 19 are arranged in the paths of either set of these beams to rotate the plane of polarization so that all the light projected is polarized in the same plane.
