IPC: D06F39/08
Filed: 1970-01-13
Abstract: 1,231,762. Washing machines. FEDDERS CORP. 13 Jan., 1970, No. 1618/70. Heading D1A. [Also in Division F2] A changeover valve having an inlet 30 is operable to connect the inlet with a first outlet 28 during a first supply phase, and automatically to change over to a second outlet 27 on termination of the first supply phase in preparation for a next succeeding supply phase. The valve comprises a valve member 36 with operating member 35, 38 held in a position where the first outlet is open by a retaining means against the bias of a spring 37. On commencement of the first supply phase a pressure responsive means such as diaphragm 44 is operative to place the retaining means in a condition for release by subsequent loss of pressure when this phase is terminated. As shown in the first position, a handle 51, resiliently connected to the operating member 38 by a spring 52, has been retracted to place a detent 58 behind a pivoted latch 56 carried by a spring loaded plunger 54 which cooperates with the diaphragm 44. When the first phase commences, pressure through restriction 43 lifts the latch to a position where a shoulder 59 engages a second detent 60 .the first detent being released. With subsequent loss of pressure, the handle is released and the valve changes over. The latch 56 may be released by a press button 62. In a washing machine, Fig. 1 (not shown) suds water in the tub (11) is removed by a reversible pump (16) to a conservation tank (22) through the changeover valve (25). In a succeeding pumping operation in the same direction, rinse water removed from the tub is automatically discharged to a drain tank (23). The suds water is returned to the tub by a reverse pumping operation.

Abstract: 1,231,799. Push-button switches; electromagnetic switches. J. STALLEBRASS. 4 July, 1968 [18 July, 1967], No. 32912/67. Heading H1N. [Also in Divisions G4 and H2] An annunciator comprises two lamps 6a, 6b, lamp 6b being energized in a first mode (e.g. continuously) under normal conditions and in a second mode (e.g. flashing) after acknowledgement of a signal received from lamp 6a indicating abnormal conditions; lamp 6a being energized in one mode (e.g. flashing) in response to abnormal condition and in a further mode (e.g. continuously) in response to correction of said abnormal condition. Lamps 6a, 6b are preferably contained in a housing 5, lamp 6a having a red lens. Under normal conditions, reed switches 14a, 14b are in the positions shown so that the white lamp 6b is energized from a supply 15b. In the event of a fault or other abnormal condition, reed switches 14a, 14b are set magnetically to their other positions by a valve position sensor 28, extinguishing lamp 6b, connecting lamp 6a to a low frequency flashing supply 15a and sounding an alarm. This condition is acknowledged by the operator by depression of cap 7 which is connected to a pawl 9 which operates a cam 11 via a ratchet 10 so as to change the setting of switches 13a, 13b. This acknowledgement is indicated by lamp . 6a being continuously lit. When the fault has been cleared, reed switches 14a, 14b are restored to the positions shown, hence lamp 6a is extinguished while lamp 6b flashes as a "fault cleared" signal. Further acknowledgement of this by depression of the cap 7, causes rotation of cam 11 which restores the setting of switches 13a, 13b and restores lamp 6b to continuous illumination. The switch 13 may include a third set of contacts 13c arranged to control an actuator 25 for an hydraulic valve. Fig. 3 (not shown) contacts 13c control a fan, whilst reed switches 14a, 14b are operated in response to change in temperature of a component cooled by the fan. Alternatively, if the fan is replaced by a pump, contacts 14a, 14b can be controlled indicative of the pressure in the system supplied by the pump.

Abstract: 1,238,196. Automatic control of electromagnetic beams. WESTERN ELECTRIC CO. Inc. Nov.1, 1968 [Nov.2, 1967], No.51923/68. Heading G3R. An electromagnetic beam is maintained in focus along a waveguide by automatically controlling a first pair of lens in dependence on signals from elements detecting the width of the beam at three longitudinally spaced locations between an adjacent second pair of lens. In Fig.4, electromagnetic energy is transmitted from left to right along the waveguide shown through lenses 40, 41, 42, 43 which may be solid or gaseous and each of which is adjustable by varying longitudinal position, reflecting curvature, or electric heater energization to control focusing of the beam in two directions at right angles. Elements 45, 46, 47, e.g. photo-cells arranged on each side of the beam, detect the width of the beam at three longitudinally spaced locations between adjacent lenses 42, 43 and are associated in pairs with differential amplifiers 48, 49, e.g. of the integrated circuit type, controlling reversible motors 52, 53 which adjust lenses 40, 41 to maintain a desired width of beam relative to one axis. A second similar system (not shown) maintains the width of the beam relative to a perpendicular axis. Known automatic control systems (not shown) may maintain the beam in a central position within the waveguide.

Abstract: 1,251,185. Colour television. RANK ORGANISATION Ltd. 18 Nov., 1968 [5 Dec., 1967], No. 55245/67. Heading H4F. Relates to a means for controlling a reference oscillator 20 operating at the subcarrier frequency in a PAL colour television receiver by means of the two colour component signals E u  and E v  which have been separated from the composite colour video signal; alternatively the phase alternation may be effected at field frequency. The colour components, when separated in the PAL receivers as shown in Fig. 1, contain no phase errors since the errors in successive lines are cancelled out. Thus the phase of one, or a combination of both, of the components may be compared in a phase detector 22 with the phase of the reference oscillator in order to ensure that the oscillator locks to the subcarrier frequency and to obviate the possibility of it locking to one of the adjacent frequency components in the frequency spectrum of the output of the oscillator. The error signal from phase detector 22 is used to effect coarse control of the oscillator 20, fine control of the oscillator 20 being effected by the burst gating pulse derived from the chrominance signal by means of a burst keyer 18, the phases of the outputs from the keyer and oscillator 20 being compared at 19 to give the fine control signal.

Abstract: 1,251,829. Coated sheet materials. CARL FREUDENBERG. 19 Dec., 1968 [27 Feb., 1967], No. 60477/68. Heading B2E. [Also in Division D1] A leather substitute comprises a fleece in which predominately all the fibres are synthetic fibres and throughout which there is uniformly distributed discrete tanned particulate collagen and which is bonded by coagulated synthetic resin or natural rubber and in which the strength of the bond between adjacent fibres is predominately due to said bonding agent. The fibres can be formed of continuous or staple polyamide, polypropylene or polyester fibres, or mixtures thereof. Natural fibres and shrinkable fibres, such as wool, can be included in the fleece. The shrinkable fibres are preferably shrunk with hot air or steam prior to impregnation with binder. The fleece can be formed by carding and cross-lapping. The fleece may be stabilised prior to impregnation by needling, or bonding thermoplastic fibres in the fleece, or by forming the fleece with incompletely set continuous filaments or by wetting the collagen particlescontaining fleece to cause the collagen to swell and stick to fibres. The collagen particles, which may contain some fibrous collagen, can be formed by grinding a tanned or untanned skin or synthetic collagen structure formed by casting or extrusion. The collagen particles can be added to the flecce during carding. The impregnant may be a solution or dispersion of natural rubber or a polyacrylate, polyurethane or isoprene polymer. After coagulation the binder can be cured and vulcanised. The bonded fleece can be tanned with aldehyde. The bonded fleece can be coated with polyvinyl chloride, polyurethane, neoprene or a styrene-butadiene copolymer. The coating can be printed or embossed.

Abstract: 1,253,116. Shaping the surfaces of bricks. N. E. L. LINDVALL. 24 Oct., 1969 [6 Nov., 1968], No. 52259/69. Heading B5A. Bricks 5, compression moulded in a rotary table compression moulding machine, are fed to a conveyer 11 prior to firing in an autoclave and have their upper surfaces shaped by passage under a pulley-driven rotating shaft 14 carrying sets of radial steel blades 19 and 20. The outer blades 19 are longer than the inner blades 20 and the edges of the blades are curved to give an upwardly convex shape to the upper surface of the bricks. Each set of blades is carried on the shaft by a separate sleeve 18 to which the blades are bolted. In a second embodiment, blades 19 and 20 have flat serrated edges and are of the same length to give a flat-ridged upper surface to the bricks. In the embodiment shown in Fig. 2, the shaft is transverse to the direction of movement of the conveyer since the bricks are longitudinally laid on the conveyer. Where bricks are laid transversely on the conveyer, the shaft is located longitudinally and is driven across the conveyer along guides which, if the conveyer is moving continuously, move with the conveyer during the shaping operation (see Fig. 5, not shown). In another embodiment, shown in Fig. 8, the shaping means consists of a rotary steel wire brush having a concave working surface, splaying of the bristles being prevented by side plates 31.
