Filed: 1970-11-23
Abstract: 1294160 Flight simulator SINGER CO 23 Nov 1970 [4 Dec 1969] 55545/70 Headings B7G and B7W A flight simulator comprises means for mounting a control for movement in opposed directions from a central reference position, and, for providing a realistic feel, first and second springs 48 and 52 for urging the control towards that position in the respective directions and stop means 56 and 58 for preventing movement of each of the springs past the position of each corresponding to the control being in its central position. The control, for example a rudder pedal 14, is connected by a cable 18, which may be provided with a tension adjusting device 36, to a rod 22 connected by a cable 30 to the other rudder pedal (16), Fig. 1 (not shown); the rod 22 passes through a fixedly mounted cylinder 24 and has a central collar 44 and flange 46 which on movement of the rod engages one of annular bushings 50 and 54 and compresses one of the springs 48 and 52. The other of the springs is prevented from acting on the flange 46 by the engagement of the corresponding bushing with the stop pins 56 and 58. The springs are retained in the cylinder by end caps 40 and 42 which may be screw-threaded and may be provided with sprockets (74) and (76), Fig. 5 (not shown), driven by servomotors (82) and (84) for moving the caps in or out of the cylinder to adjust the loading on the respective springs; alternatively the caps may be fixed and the cylinder rotated by a single servomotor. The position of the control may be represented as an electrical signal by the cable 30 carrying a pin (62), Fig. 4 (not shown), which engages a sprocket chain (64) which drives rotary potentiometer (72).

Motor 36 is then stopped, a solenoid (62) de-energized so that a latch holds the magazine in the selected position, and motor 50 is energized to transfer the selected cartridge to playback unit 20 which is activated by a cartridge-operated microswitch. A metal foil on the tape initiates return of the selected cartridge from the playback unit 20 to the magazine.

Abstract: 1293996 Water supplies JACUZZI BROS Inc 16 Dec 1970 [15 April 1970] 59658/70 Heading E1X A water supply system comprises a motor driven pump supplying at least one service line, and switch means responsive to the opening of, and to the consequent pressure drop in, the, each or one line to energise the motor. Pump 1, Fig. 1, is driven by motor 3 to pump water from source 5 into line 11. Pressure switch 23 is operated by pressurisible device 25 to switch the motor on at one line pressure and off at a higher line pressure. Device 25 includes expandable tube 29 which expands, when receiving water via valve 27, to actuate switch 23. Valve 27, Fig. 2, comprises valves 53 and 51. When top 13 is opened line 11 is drained and device 25 discharges water via valve 53. The contracting tube 29 actuates switch 23 to start motor 3. The pumped water opens valve 51, closes valve 53 and isolates device 25, which remains at low pressure, by raising disc valve 71 against tube 57. When top 13 is closed valve 51 closes and its legs 67 remove disc valve 71 from tube 57 to admit water to tube 29, which expands to stop motor 3. In a modification, Fig. 5, pressurisable device 25 is connected directly to line 11, as is pressure switch 23 via passage 103. Disc valve 109 serves to seal passage 103. The expandable tube of the pressurisable device preferably has a capacity of twelve ounces of water.

Abstract: 1282230 Sweep generator IWATSU ELECTRIC CO Ltd 23 Dec 1970 [27 Dec 1969 (2)] 61207/70 Heading H3T In a sweep generator of the type in which triggering during the flyback is prevented by a hold off pulse, jitter caused by coincidence of the end of the hold off pulse with the presence of a trigger or synchronizing pulse is prevented by varying, in response to the coincidence, the period between the beginning of a triggered sweep and the end of the hold off pulse corresponding thereto. As shown in Fig. 4, the trailing pulse edge of the hold off pulse 14 generated by 4 is differentiated and the coincidence of this pulse 15 with a synchronizing pulse is used to adjust a control voltage 17 which varies the length of the hold off pulse. If coincidence reoccurs, a further level 17 is produced to widen the hold off pulse further. A digital to analogue converter comprising three pairs of NAND gates with their outputs resistively coupled to a load generates a voltages output proportional to the number of pulses 16. The signal from the synchronizing circuit may instead be taken from the output of the gate while the differentiating circuit may be replaced by or used with a delay line circuit. The output of 7 may be used to control the height to which the ramp waveform 13 reaches, and thereby the point at which the hold off signal is generated so introducing a delay (Fig. 14, not shown). The width of the hold off pulse may also be varied. The AND gate (Fig. 6, not shown) comprises two diode inputs to a tunnel diode monostable driving a transistor, the output of which drives the digital to analogue converter.

Abstract: 634,594. Knitting-machines. HEMPHILL CO. July 30, 1947, No. 20686. Convention date, May 24, 1939. [Class 74 (ii)] A vertically swinging feeder for elastic yarn operates in advance of a binder and cutter, the raising of the feeder causing the yarn to be carried into a notch in a horizontally movable element of the binder and cutter. The feeder comprises a pivoted arm 16 having a longitudinally adjustable extension 19, at the end of which is attached a plate 21, capable of vertical adjustment, through which plate runs the yarn. The feeder is raised by an arm 26 through the medium of levers operated by a pattern drum. The cutter and binder comprises a member 42 movable between fixed plates 39, 47, the plate 47 being adjustably pressed on the member 42 by a spring 50. The member 42 is projected radially into the needle circle by levers 53, 56 operated by a pattern drum, to receive the thread in a notch 46 as the feeder is raised. The member 42 is retracted by a spring to cut the yarn between sharpened edges of the notch and the plate 39 and trap it between itself and the plate 47. Specification 20101/09 and 7132/10, [both in Class 74 (ii)], are referred to.

Abstract: 732,624. Signalling over power circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 18, 1953 [Aug. 21, 1952], No. 22747/53. Class 40 (4). Street lights are extinguished and loudspeakers connected to the lighting circuit are brought into use under the control of a circuit at a central station. Switch 4 normally connects mains supply M to power lines 1 so as to light lamps 5. When the switch 4 is thrown, manually or by remote control, it connects a V.F. amplifier 2 in series with a direct-current source 3 to the lines to energize relay 8, thus cutting off the lights 5 and connecting up the loud-speakers 6. The loud-speakers receive the V.F. signals over condenser 10 and are protected by fuses 9. In a modification, Fig. 2, the switch 4 in right-hand position lights the lamps 5. When the switch is moved to midposition it applies direct current to polarized relay 8 which changes over its contact 8<1> to extinguish the lamps and connect up the loudspeakers so that when the switch 4 moves to left-hand position the V.F. voltage 2 is applied to the loud-speakers. In the reverse direction when the direct current is again applied the relay 8 changes over its contacts again.

Title: A.C. motor control apparatus
IPC: G05D23/275
Filed: 1979-06-20
Abstract: A synchronous motor 11 controlling the valve 13 of a central heating system is energised from an A. C. supply by closure of thermostat 42, until cam 53 changes over switches 51, 52 to respectively break the AC supply and reconnect the motor via diode 17 and resistor 18, thereby D.C. braking the motor and holding it in a mid-position of the valve. Resistor 18 limits the current and hence the residual magnetism produced in the motor, whereby a spring 20 can return the motor to its original position when thermostat 42 breaks the D.C. to the motor. To ensure that spring restoration remains effective after increase of motor friction with time, a circuit is provided through thermostat 43, switch 51 and a resistor 44 chosen to supply the motor with low valve A.C. which partly reduces its residual magnetism when thermostat 42 disconnects the direct current. Operations of the motor 11, a pump motor 32 and heating apparatus 30 are described for various heating requirements of zones 1 and 2. <IMAGE>
