Title: Improvements in or relating to apparatus for displaying line traces on a cathode-raytube
IPC: G01R13/20
Filed: 1964-05-26
Abstract: 1,087,312. Electric analogue calculating. J. I. P. JONES, and R, J. P. JONES. Aug. 25, 1965 [May 26, 1964], No. 21661/64. Heading G4G. [Also in Division H4] A straight line trace the length of which is proportional to the magnitude and the orientation of which is proportional to the direction of a vector quantity is produced on the screen of a cathode-ray tube by deflecting the beam in orthogonal directions under the control of respective voltages representative of orthogonal components of such vector quantity. In the basic arrangement the orthogonal component voltages V x , Vy (Fig. 1) which may represent a vector quantity such as wind velocity and direction, are applied via respective equal resistors R 1 , R 2  to a chopper circuit 1 and thence via equal resistors R 5 , R 6  (of lower value than R 1 , R 2 ) to equal value capacitors C 1 , C 2  forming a pair of matched integrating circuits the chopper being switched by a generator 2 such that the capacitors charge through R 1  + R 5  and R 2  + R 6  respectively and discharge through R 5  and R 6  respectively in a sequence repetitive at the frequency of generator 2 (e.g. 50 c.p.s.). The voltages thus developed across the capacitors are then utilized to control the X and Y deflection circuits of a cathode-ray tube the beam of which is suppressed during part of the charge time of C 1 , C 2  (Fig. 2, not shown) to remove 180 degrees direction ambiguity by means of blanking pulses from a generator 3 synchronized by generator 2. The blanking pulses may be either rectangular and of adjustable width or a differentiating circuit may be employed to produce a gradually decaying blanking voltage. When the deflection amplifiers are D.C. coupled the vector traced has the form depicted in Fig. 3 (not shown) whilst A.C. coupled amplifiers result in the display of Fig. 4 (not shown). When a plurality of vector traces is required to be displayed (e.g. representative of wind direction and velocity of different positions on an airfield, Fig. 8, not shown) a like plurality of orthogonal components is supplied in filters 4 (Fig. 5, not shown), which remove undesired fluctuations, to a bank of time-division multiplex switches 5 operated by a shift register 6 to supply the component voltages, in pairs, to the choppers 1 and thence via the integrators 7 to respective summing amplifiers 8, 9 also fed with voltages determining the positions in which the traces are to be produced on the tube screen. Additionally, the component voltages may be arranged and supplied either to filters 4 or switches 5 to produce a further trace showing the spatial-mean vector wind against a calibrated scale (Fig. 8, not shown). Circuit details of one section of the switches 5 and shift register 6 are described with reference to Fig. 6 (not shown) and the waveforms produced during one cycle of operation (<SP>1</SP>/ 50  sec.) of the latter are depicted in Fig. 7 (not shown). A line drawing produced by the arrangement of the invention is illustrated in Fig. 9 (not shown).

Title: Domestic washing machines
IPC: D06F45/12
Filed: 1956-07-16
Abstract: 801,643. Washing-machines. WILKINS & MITCHELL, Ltd., and WILKINS, E. W. June 28, 1957 [July 16, 1956; Feb. 16, 1957], Nos. 21861/56 and 5343/57. Class 138 (2). In a washing-machine of the kind in which an impeller 13 mounted in the lower part of the tub 12 is continuously rotated through a pulley and belt drive from an electric motor 15 and in which a clothes wringer 20 is provided on top of the machine, the wringer is driven through a pulley and belt transmission 43, 44 under the control of a clutch mechanism associated with a pulley 18 which is normally drivingly coupled to the impeller, the arrangement being such that the impeller drive is automatically disconnected when the wringer drive is brought into operation. As shown, the drive from the motor 15 is connected by means of pulleys 16 and 18 and belt 19 to shaft 14. Pulley 18 is slidable along shaft 14 under the action of spring 35 which normally presses together the faces of the cone clutch formed between the outer surface of clutch element 24, which is rigidly fixed to shaft 14, and the inner conical surface of pulley 18. A driving peg 25 is attached to pulley 18 so that when the pulley slides up shaft 14, the peg can engage one end 26 of a coilspring clutch 27 attached to pulley 29. This pulley drives the bottom roller 42 of the wringer through pulley and belt transmission 43, 44 and a worm and wheel reduction gear 45. When it is desired to bring the wringer into operation, a pedal 49 which pivots about a bearing 57 is depressed and raises lever 50 which makes contact with ball 33. The pulley 18 and housing 32 slide up shaft 14 disengaging the cone clutch drive and engaging the coil-spring clutch 27 which then drives the rollers through their belt 43. To prevent drive to the impeller being reconnected as soon as the pedal 49 is released, the push-rod 54 is depressed and moves lever 51 into such a position that lever 50 is prevented from returning to its rest position and thus coil spring 35 remains compressed, the surfaces of the cone clutch do not re-engage and drive to the impeller remains interrupted. By depressing and releasing pedal 49, drive to the wringer can be connected and disconnected at will while the drive to the impeller cannot be recommenced until push-rod 54 is raised.

Abstract: 711,120. Ventilation. GARRETT CORPORATION. Sept. 2, 1952 [Sept. 15, 1951], No. 22052/52. Class 137. [Also in Group XIII] In an aircraft or like ventilating plant, the compressor, which normally supplies air, via cooling means, to the cabin, is enabled, by adjustment of valve means which connect the cabin to the air-intake, to suck air from the cabin and discharge it overboard. The compressor 10 is driven from the shaft 13 of a main engine 14 of an aircraft, through a slip clutch 27 and a change speed gear 12 and discharges through a heat-exchanger 19 and turbine 21, which is coupled with the compressor 10 to the cabin space 25. The speed-changer control lever 29 is moved, according to engine speed, from the neutral position N into position H to produce a step-up drive to the compressor, when the aircraft is on the ground or to position D to produce a direct drive when the aircraft is cruising. A valve 33 is operable to bye-pass a greater or lesser quantity of air around the turbine 21, the valve being actuated, against a returning-spring, by a relay 37 responsive to the movements of a floating lever 40 which is under a control compounded of engine-speed responsive means 41 and air-intake measuring means 42 ... 46. The fan 42 in the compressor intake 17 drives a generator and amplifier 43 connected to a solenoid coil 44, the armature 45 being loaded by a spring 46. The armature is connected to the floating lever 40 the compounded movement of which is transmitted by a rod 38 to a slide valve 37 which controls the admission of oil pressure, derived from a gear pump 47, to one or other side of the piston 36 whereby the extent of opening of the valve 33 is determined. Cabin temperature is controlled by a thermostat 55 connected to a solenoid 54 which, when energized, opens a valve 52 to permit air to pass from the compressor outlet 18 through the passage 51 to the outlet side of the turbine, thus bye-passing the heat exchanger and the turbine. A pressure control valve 56, pressure relief valve 57 and vacuum relief valve 58, all of conventional form, are provided in the cabin. When the aircraft is on the ground, there is no rammed air flow through the passage 20 of the heat exchanger. A valve 64 is then opened to supply air from the compressor to a turbine 61 which drives a fan 59 through step-up gearing 60. When the compressor is used merely to draw air into the cabin by sucking air therefrom, a valve 67 is pivoted into the dotted line position, so that the duct 24 is joined to a duct 65 and an overboard-discharge port 68 is opened. The valve 67 is interconnected with a pivoted valve 66, which is simultaneously moved to the dotted line position, so that the compressor intake 17 is blanked off. The compressor suction is thus from the cabin through the ducts 24, 25, 17, and the air is discharged overboard at 68.
