Title: Speed reducing positioning device in a numerical control system
IPC: G05B19/35
Filed: 1968-12-20
Abstract: 1,223,927. Programmed control of machine tools. MITSUBISHI DENKI K.K. Dec.20, 1968 [Dec.22, 1967], No.60809/68. Heading G3N. In a numerical control apparatus for a machine tool a controlled member is finally positioned at a speed dependent on the distance between actual and commanded positions the speed reduction commencing from a position determinedby a comparison between a predetermined speed signal and a signal representing the distance between the actual and commanded positions. As shown, position and speed information from a punched tape 10 is fed from a reader 12 through an input control circuit 14 to a position counter 16 and a speed register 18. The information in counters 16, 18 is applied to digital-to-analogue converters 20, 22 and the D. C. outputs fed to a comparison and switching circuit 24. The output of the position counter 16 is also fed to a circuit 28 monitoring the digital value contained in the counter 16 and sensing when this value falls to zero, at which the command and actual positions coincide. A residual count in the counter 16 gates a circuit 30 enabling pulses from an oscillator 26 to be fed to the counter 16 and to a phase modulator 32 which converts the number of applied pulses to a variable phase low frequency square waveform which is fed to a phase difference detector 34. The detector 34 is also responsive, through an angle-to-phase conversion circuit 44, to the output of a resolver 42 coupled to a table 36 and the detected phase error is applied to a D. C. motor 48 retro-actively positioning the table. The voltage comparing and switching circuit comprises gate circuits whereby the pulse rate of the oscillator is determined by the analogue signal dependent on the contents of speed register 18 or, when the member approaches the commanded position, by an analogue signal proportional to the residual count in the position counter 20.

Title: Electric power system
IPC: B60K6/10
Filed: 1968-12-23
Abstract: 1,255,027. Motor vehicle propulsion systems. UNION CARBIDE CORP. 23 Dec., 1968 [26 Dec., 1967], No. 60939/68. Heading B7H. [Also in Division H2] A propulsion system for a vehicle comprises a flywheel 1 containing battery 2, and a dynamoelectric machine having armature 4 and field poles 3, the latter being fixed to the flywheel. The battery is connected to the armature through switch 18. A friction disc 8 is mounted on the flywheel and engages wheel 9 which is slidable along splined shaft 11 to drive the wheels 12. A mechanical feed-back system comprises shafts 13, 14, and opposed overrunning clutches 15, 16, which cause the armature to rotate oppositely to the flywheel and at a speed proportional to the vehicle velocity. A worm-gear 17 prevents the armature from driving the shaft 14. The speed differential between field and armature tends to remain at a steady value. A reduction in the differential results in motor action tending to accelerate the flywheel, while an increase in speed differential causes generator action to charge the battery and decelerate the flywheel. In modifications, the dynamo-electric machine is mounted in other locations with respect to the flywheel, the armature being connected to the flywheel instead of the field, for example. The machine may be used to drive loads other than vehicles.

Patent GB-2083979-A (GB)
Title: Radio transmitting and receiving apparatus
IPC: H04B1/44
Filed: 1981-08-27
Abstract: A simplex radio transmitting and receiving apparatus has a transmission blocking means which prevents selection of the transmitting mode of the apparatus while a signal of predetermined strength is being received by the apparatus at the time the press-to-talk key is operated. An over-ride circuit enables the blocking means to be disabled in an emergency or if another transmitter has been left operating in error. The over-ride circuit can be activated by, for example, repeated operation of the press-to-talk key, and ceases to operate when the key is released to return the apparatus to its receiving mode. Also disclosed is a transmission control means which can be used to modify existing transceivers to operate in accordance with the invention.
