Title: Improvements in and relating to remote indicating apparatus
Inventor: SELKA SOLOMON MAXIMILIAN
IPC: G05D3/14
Filed: 1966-01-24
Abstract: 1,135,284. Measuring distances. RELIANCE GEAR CO. Ltd. 24 Jan., 1967 [24 Jan., 1966], No. 3072/66. Heading G4D. [Also in Division G1] In the measurement of linear or rotational displacements of, e.g. a slide of a machine, using coarse and fine servo systems (see Division G1), of which the motors M also drive coarse and fine indicators, the fine indicator comprises a pointer moving over a fixed scale calibrated, e.g. in 1000th of inches, driven by the motor of the fine servo system, and the coarse indicator comprises rotating drums calibrated, e.g. in 10th of inches, inches, 10s and 100s of inches driven by the motor of the coarse servo system. The lowest decade drum may alternatively be driven by the fine servo system motor. Misinterpretation of the slide position as the pointer of the fine indicator passes through 0 may be prevented in two ways dependent on which motor drives the lowest decade drum. If it is driven by the fine servo motor, Fig. 4, through gearing from a shaft 101 which drives the pointer, a window 111 of double height is provided, through which two numbers on the drum are visible, having two illuminable arrows 105, 106 adjacent the window to indicate which number is relevant. One of these arrows is illuminated dependent on whether relay 104, controlling a switch connecting either lamp 107 or lamp 108 to a D.C. source, is energized or not. Energization of the relay is controlled by a wiper 103 contacting a disc 102, rotating on shaft 101, half of which is electrically insulated. Thus when the pointer is between 50 and 0, the relay 104 is energized, causing arrow 105 to be illuminated and between 0 and 50, arrow 106 is illuminated. Alternatively when the lowest decade drum is driven by the coarse servo motor, Fig. 6, as the fine pointer passes through zero, the drum is shifted forward by an electromechanical device by half the pitch between figures, and is retarded by the same amount as the pointer passes through 50, Fig. 5 (not shown). The drum is mounted on a shaft 611 and driven from motor M via gears 619, 620 and screw gears 613, 612, gears 619 and 613 being mounted on a shaft 614 which is free to move axially between stops 616, 618, movement of the shaft causing rotation of the drum. The stop 616 is adjusted so that the drum is advanced or retarded by <SP>1</SP>/ 20  of a revolution, i.e. the required half pitch, by this movement. The shaft is normally spring biased against stop 616 and is retracted by energization of coil 625, whose armature 623 is carried on the shaft 614. The coil is energized for half a revolution of the fine pointer, i.e. between 50 and 0, as for the previous embodiment.

Title: Improvements in windscreen wiper systems
IPC: B60S1/08
Filed: 1963-01-28
Abstract: 1,035,161. Windscreen wipers. TRICO PRODUCTS CORPORATION. Jan. 28, 1963 [Jan. 29, 1962], No. 3447/63. Heading A4F. [Also in Division H2] A vehicle windscreen wiper system includes a power train connected to a continuously-operable power supply and including a rotary wiper motor, and a timing control means including a mechanical member automatically movable cyclically against manually adjustable resistance to interrupt the power train and cause actuation of the wiper with intermittent dwell periods. The electric wiper motor 12, Fig. 2, is controlled by a dashboard unit comprising a rotary switch having a contact carrying plate 26 (Fig 3, not shown) rotatable by a knob to bring selected contacts thereon into engagement with selected of contacts 44 to 48 on a base plate. When the knob is set for continuous wiper operation the wiper motor 12 is connected continuously through the rotary switch and the ignition switch 73 to the battery 72. When intermittent wiper operation is desired, e.g. during conditions of light rain, the rotary switch is set to establish the circuit illustrated. The wiper motor 12 is then energized from the battery 72 through the ignition switch 73, the rotary switch, and the contacts 92, 93 of a switch which is opened intermittently by an armature 101 on energization of a solenoid 99, the circuit of which is also broken when the contacts 92, 93 open. The return of the armature 101, to close the contacts 92, 93 is effected by a spring 102 and is delayed for the period required for air to bleed from a chamber 110 above a diaphragm 105 secured to the armature 1. This period, which is the period of dwell of the wipers, is controlled by an adjustment at the dashboard unit to vary the rate of air flow from the chamber 110 through a pipe 129. A diaphragm device 147 is provided which, in response to acceleration of the vehicle, over-rides the timing control means so as to cause continuous wiper operation if the rotary switch is set for intermittent operation. The device 147 is responsive to a decrease in the manifold vacuum on acceleration to close contacts 164, 165 and maintain contacts 92, 93 open. Alternative means are described for causing continuous wiper operation in response to acceleration of the vehicle.

Title: Digital compass
IPC: G01C17/30
Filed: 1970-01-23
Abstract: 1285832 Digital compass LUNDY ELECTRONICS & SYSTEMS Inc 23 Jan 1970 [10 Feb 1969] 3475/70 Heading G4H In a digital compass a magnetic field direction sensor is rotated about a vertical axis and generates a field pulse when aligned with the magnetic field and for each revolution clock pulses generated by the rotation of the sensor are counted in the interval between the field pulse and a reference pulse as an indication of the direction of the magnetic field. The direction sensor is a Hall effect device which is gimballed horizontally. The reference pulses and clock pulses are produced photo-electrically by apertured plates, the reference pulse being generated as the direction sensor is aligned with the longitudinal axis of the ship or vehicle carrying the compass and one clock pulse, or more if greater sensitivity is required, is generated for each degree of rotation of the sensor. The reference and field pulses set and reset a bi-stable circuit which opens an AND gate to pass clock pulses to a three-decade binary counter during the interval. The fixed pulse after a short delay clears a memory of the count of the previous revolution and enables the memory to accept the count of the present revolution and after a further delay clears the counter for the next revolution. The contents of the memory after decoding are visually displayed as a number of degrees representing the bearing of the ship or vehicle. The counter can be preset with the magnetic variation or declination for each revolution and is reset to zero if it counts to 360 degrees.

Title: An improved electric motor protection switch
IPC: H01H71/74
Filed: 1945-02-13
Abstract: 601,729. Electrically-tripped switches. LANDIS & GYR SOC. ANON. Feb. 13, 1945, No. 3573. Convention date, Feb. 21, 1944: [Class 38 (v)] The time-lag and quick-acting releases for a motor-protection switch are simultaneously adjustable to the rated current and a multiple thereof respectively and are combined in a small box which forms a constructional unit for insertion in the switch. The moving contacts 1 of a three-pole switch are actuated by an electromagnet (not shown) which has a switch 15 in its energizing circuit. The normally fixed contacts 2 are mounted on insulating slides 3 biassed away from the contacts 1, but latched-in by detents 6 engaging half-cylinders 7, each carried by a two-arm lever 9, 10 pivoted coaxially with the halfcylinders 7. The motor current in each pole flows through contacts 1, 2, co-operating contacts on the switch and the box, the winding 33 of a relay, a bimetal strip 18 and further contacts on the box and switch. On normal overload, the strip 18 flexes about its fixed end 18a and raises a screw 21 to rotate a shaft 19 and a half-cylinder 19a, allowing a lever 25 to pivot about a lever 26 and bpen at 15 the energizing circuit of the switch-holding magnet, thereby opening all poles. On short-circuit, the winding 33 attracts an armature 34, which strikes the lever 10 to unlatch the contact 2 at 7, 6 and open one pole. As the slide 3 moves back, it strikes a manual re-set lever 13, 14 which, by striking an abutment 16, opens the switch 15, de-energizing the switch-holding magnet and opening all poles. The relays, bimetal strips, shaft 19 and levers 25, 26 are mounted as a unit in a box 17 together with a shaft 30 carrying cams 28, 29 and a slotted disc 37. By turning the disc 37, which indicates the rated current, the cams 28, 29 adjust the release point of the latch 19a, 25 and the tractive power of springs 35, to vary the operating currents for the bimetal strips and the relays, respectively. This adjustment maintains a constant ratio of operating currents, which is set by prior adjustment of screws 21, 36. Quenching chambers 5 house the contacts 1, 2 and one or more quenching coils 4. Specifications 588,724 and 588,738 are referred to.
