An electronic watch comprises a Piezo-electric quartz crystal oscillator coupled by a frequency dividing circuit to a circuit providing pulses for a motor driving indicating mechanism, the frequency dividing circuit being a binary circuit each stage of which divides the frequency by two, and the frequency dividing and pulse providing circuits comprising logic elements and being such that the ratio between the duration and the period of the pulses is different from 0À5. The frequency divider may comprise 14 stages the outputs from two different stages being supplied to a NOR gate comprising transistors T 11 , T 12  Fig. 3, (not shown) to obtain pulses of a desired duration which are applied to a further NOR gate together with an output from the 14th stage of the frequency divider. The output from the further NOR gate renders transistors conducting to provide pulses for operating the motor driving time indicating mechanism. A third NOR gate is also provided to receive the output from the first NOR gate and also a second output from the 14th stage of the frequency divider of opposite phase from the first output. Two series of pulses are thus obtained for operating the motor. In a further embodiment the output from a frequency divider is applied to a control circuit for operating a motor comprising a vibrating strip. The control circuit includes a monostable multi-vibrator the duration of the output pulses from which are controlled in response to a voltage generated by the motor.

The insulated conductors are enveloped by a common synthetic thermoplastics sheath 5 which is fairly thin to minimize the elastic flexibility of the core 2 and for the same reason the conductors 3, are of soft copper and are free to move within the insulation 4 which is also free to move in the sheath 5. The conductor 3 may alternatively be of soft aluminium. To allow additional conductors to be drawn in or existing conductors to be replaced the wires occupy only a quarter or a sixth of the internal cross-section of the conduit. The minimum diameter of the conduit is preferably not less than 10 mm., and may be 13 mm. for a two conductor assembly and 16 mm. for a five conductor assembly. Extrusion method.-Hot plasticized synthetic resin such as p.v.c. is fed from the extruder 14 to the crosshead die 13 and the tubular plastics conduit which is extruded is corrugated by being forced by air pressure against the inside walls of two co-operating chains of half moulds 17, while the core assembly 2 is continuously introduced into the conduit via a central opening in the crosshead die 13. Compressed air from a pipe 15 is conducted to the outlet orifice of the die and a gauge pressure is maintained by the terminal piston head 16. Electrical conductors 3 with insulation 4 pass through a vacuum chamber to the crosshead die 10 where they are provided with a sheath of a thermoplastics material, such as p.v.c., the vacuum causing the sheath to tightly embrace the insulated conductors. Prior art.-Reference is made to German Auslegeschrift Patent Specification 1,263,129 concerning a thick-walled outer insulating pipe with which the insulation for one or more electrical conductors inside the pipe is integrally formed.

Title: Antiskid vehicle brake system
IPC: B60T8/42
Filed: 1970-12-22
Abstract: 1306749 Antiskid braking systems FORD MOTOR CO Ltd 22 Dec 1970 [15 Jan 1970] 60799/70 Heading F2F In a vehicle antiskid braking system signals V w  representing wheel speed are fed to a memory 10 giving an output signal V 0 , indicative of vehicle speed at a time = 0 during the braking mode, which passes to a point 58 receiving a further signal E 0  indicative of instantaneous vehicle speed, an adder circuit 56 passing a signal representative of the resultant of signals V 0  and E 0  at point 58 to a comparator 32 where it is compared with wheel speed V w  to cause a brake release signal to be sent to a pressure modulating device when slip exceeds a precalibrated level. Feedback is provided which allows the system to anticipate the response of the modulator so that a correcting signal is developed before the modulator is allowed to complete that response. Wheel speed is measured by a toothed disc 12 and variable reluctance speed pick up 16 the signals from which are preamplified at 24 and fed to a frequency to voltage converter the output signals therefrom passing to memory 10 by way of a normally used switch 30. Vehicle speed is measured by integrating a deceleration representative signal from an inertial accelerometer 46. When incipient wheel lock is detected a solenoid valve 128 becomes energized shifting a valve spool 132 leftwardly thereby exhausting a passage 146 leading to a chamber on the lefthand side of a piston 150 of the modulating device 148 and interrupting communication between passage 146 and a passage 144 leading to a further solenoid valve 186. If wheel slip exceeds the precalibrated valve solenoid 186 becomes energized shifting a valve spool 178 leftwards allowing fluid to pass under pressure from a pump 142 to the right hand side of piston 152 through a passage 174, causing piston 152 to be shifted leftwardly. This causes corresponding movement of a small piston 160 allowing a check valve 166, situated in a line between a master cylinder and wheel brake cylinder, to close, movement of piston 160 expanding the volume of the line to relieve braking pressure. A position feed back loop is provided including a transducer core 190 attached to piston rod 154 which varies the inductance of a coil 192 as its position changes. Before valve 166 is fully closed the movement of core 190 causes a signal to pass to an electric trigger circuit which in turn causes deactivation of solenoid 186 and corresponding movement of spool 178 thereby allowing fluid pressure on the right hand side of piston 152 to be exhausted. Piston 152 begins to return to its original position before valve 166 is fully closed, again changing inductance in coil 192. Valve 178 thus opens and closes rapidly causing piston 152 to oscillate above about an average position. Circuits for the triggering of solenoid 186, and for the integrator, adder and memory are described.

Title: Locating device
IPC: G05B19/35
Filed: 1968-12-23
Abstract: 1,223,928. Programmed control of machine tools. MITSUBISHI DENKI K.K. Dec.23, 1968 [Dec.22, 1967], No.60995/68. Heading G3N. A locating device for moving a member to a commanded position includes a means for comparing an analogue position signal with an analogue signal derived from pulses which pass through a gate only while a difference exists and a position counter holding the command position and counted down by the gated pulses which provides an output signal for controlling the movement of the member to the commanded position. As shown, a machine table 122 is driven through a speed-reduction and stop mechanism 130 by an A.C. motor 132. The position of the table is sensed by a resolver 128<SP>1</SP>, coupled to the table by a rack and pinion 124, 126. The position to which the table is to be driven is read from a punched tape 110 by a reader 112 and fed through a control circuit 114 to a position counter 116. The counter 116 is counted down by pulses, through a gate 176, from a generator 178 and the digital value in the counter is compared with a reference value in a residual distance circuit 118 which also senses when the counter is cleared. The circuit 118 is connected to a speed switching circuit 120 which causes A.C. motor 132 to translate the table 22 at high moderate, and low speeds through the mechanism 130 containing an electromagnetic clutch. The sine and cosine position values from the resolver 128<SP>1</SP> are fed to angle-to-phase conversion circuit 160, comprising an R. C. input network and an operational amplifier, the sinusoidal output of which has a phase angle, with respect to a reference signal, proportional to the mechanical angle of rotation of a shaft driving the table 122. The gated pulses from the generator 178 are also fed to a digital phase modulator 168 comprising a pulse counter 170 formed by a pulse generation and an addition/subtraction circuit, and a digital-toanalogue converter 172, comprising a frequencydivider, the output of which is a frequency-modulated signal varying in apparent phase with respect to the reference signal. The outputs of the modulator 168 and circuit 160 are compared in a phasedifference detector 166 and applied to a determining circuit 174 which, when the phase-difference is other than zero, enables the gate 176. The generation of a termination signal by the circuit 118 closes gate 176 and stops the motor 132 through circuit 120. However, table 122 will run on owing to its inertia and the phase angle signals from modulator 168 and circuit 160 will differ and this difference will be corrected at the succeeding movement of the table. In a modification, the speed at which the table is moved is also controlled.

Filed: 1979-01-05
Abstract: The highest of a plurality of input frequencies is isolated and transmitted by converting the input into pulses, and determining the p.v.f. IC16,17 output the differentiated input pulses, and these are time displaced relative to one another by high frequency three phase clock IC1, IC2, in flip-flop arrangements IC5, IC6, IC7. Provided the inputs all have the same frequency, the pulses at the outputs of the portions of IC18 will occur sequentially, according to the clock phasing. If however one input has a higher frequency, it will produce two consecutive pulses in the space between two pulses on the other lines. This occurrence is checked in IC10, comparing outputs from FW1, FW2 and IC13, comparing the faster of FW1 and FW2 with FW3. The overall output is derived from PLL IC15. The arrangement is useful for discriminating the signals received from a plurality of wheels used to measure the speed of a pipeline inspection vehicle moving in a pipe. <IMAGE>
