IPC: B26B19/00
Filed: 1969-10-31
Abstract: 1,245,357. Cutting. R. G. BERRY. 31 Oct., 1969 [5 Nov., 1968; 23 Oct., 1969], No. 53503/69. Heading B4B. [Also in Division G3] The hair of an individual's head is cut to length in accordance with a recorded programme on a magnetic tape (see Divisions G2-G3), by cutting elements mounted on a carriage movable along vertical paths uniformly angularly spaced about the head, from a level beneath the hairline to a point near the centre of the top of the head, in stepped synchronism with the tape movement. In an embodiment, Fig. 6, the cutting element 206 is mounted on the end of a shank 180 and is biased to the closed position by a spring 218 and opened by an armature 202 of a programme-controlled solenoid, not shown. The shank has a flat portion 181 insertable in a bore on the frame of the carriage for rotation about its axis and is biased by a spring 184 so as to tend to rotate in the clockwise direction. During a cutting operation, the hair is first drawn between cutting blades 208, 210, Fig. 6a, retained by fingers 212, 214, and subsequently cut at the desired length by release of the solenoid, on cessation of a programmed signal from the record medium, and the closure of the blades by the spring 218. In an alternative embodiment, Fig. 16, a cutting element comprises a stationary blade 452 and a movable blade 454, held open by a spring 462. The hair is retained between the blades by a guard wire 456 supported by an arm 458 which is displaced by a cam to allow the hair to enter between the blades. During cutting, the blade 454 is closed on the blade 452 by a lever 464 having a portion engageable by a plunger 468 of a solenoid 436 energized by a programmed signal derived from the record medium. Reference has been directed by the Comptroller to Specification 909,065.
Patent GB-1449193-A (GB)
Title: Electronic timepiece
IPC: G04G5/02
Filed: 1973-11-19
Abstract: 1449193 Electronic watches CITIZEN WATCH CO Ltd 19 Nov 1973 53673/73 Heading G3T A digital electronic timepiece has provision for fast correction or setting of the time and date displayed, by applying a higher than normal frequency signal to its time counting circuit, or, for manual correction, by repeated manipulation of a switch. In Fig. 2, only one mechanical switch 11 is used for correction of seconds, minutes and hours and for manual stepping and correction. Gate circuits 14, 15 and resistors 12, 13 offset the effects of switch chattering. The digit to be corrected is selected in dependence upon the number of the ON/OFF cycles of the switch 11 performed, as determined by a circuit 20 which enables a selected one of gates 31 to pass a 1 HZ fast feed correcting signal from a divider 29 to the appropriate counter in a time counting circuit block 5. For instance to correct the minutes digit, the switch 11 is switched ON/OFF twice causing an output of a said gate 31 in a line 33, which is applied to a minutes counter via a gate 36. Thereby the minutes display is advanced without affecting the tens of minutes counter a gate 37 being blocked by a high potential in a line 21. Similarly, the hours and tens of minutes digits can be corrected independently. A circuit 25 detects the length of time the switch 11 is ON and if more than 2 seconds signifying completion of the selection, the potential in line 26 causes a gate 30 to pass the 1 HZ correction signal to the gates 31 as stated above. Similarly, if the switch is OFF for 2 seconds a circuit 27 causes a high potential in a line 28 which resets the circuit 20 to its initial state. Alternatively the selection of the digit to be corrected may be effected in response to the length of time the switch 11 is ON or OFF. Also the fast feed may be initiated in response to the length of time the switch is OFF. In alternative embodiments Figs. 3 and 4 (not shown), initiation of the fast feed correction is delayed by a timer circuit, for a predetermined period of time, after the switch is switched ON. In Fig. 4 embodiment manual correction can be effected by repeatedly switching ON and OFF. In an embodiment Fig. 5 (not shown), there is a day and month correcting switch (538), a week correcting switch (539), a seconds switch (536) and an hours and minutes switch 537. Carry signals are prevented between the hours and days counters when correcting the hours. An up/down counter may be provided to enable the forward or backward setting of the time indication.

Title: A Regulated Supply Arrangement for an Electrostatic Precipitator.
Inventor: WINKLER HEINRICH
IPC: B03C3/68

Abstract: 1,161,828. Control circuits for electrostatic precipitators. SIEMENS A.G. 30 Nov., 1966, No. 53719/66. Heading H2H. A control system for an electrostatic precipitator 4 which is supplied from an A.C. source RT by way of a transductor 1, a transformer 2 and a rectifier 3 comprises a pair of back-to-back thyristors 6 regulating the current flowing in the control winding of the transductor 1, the firing points of the thyristors being determined by the voltage across a capacitor in a unit 9, the capacitor being charged from a D.C. source and discharged by a Schmidt trigger circuit 22 or a monostable flip-flop circuit 36 both of which are responsive to the current taken by the precipitator 4, the current being sensed by a transformer 5. Transistor 23 of the trigger circuit 22 is normally non-conductive, but an excess current condition in the precipitator causes the transistor 24 to become non-conductive, thus producing a signal for a transistor in the unit 9 which controls the discharge of the capacitor therein so producing a reduction in the voltage applied to the electrodes of the precipitator. The flip-flop circuit 36 operates similarly to control the voltage when sudden increases occur in the current taken by the precipitator. The signals for the thyristors 6 are developed in the control device 7 and, if desired, a signal 8 may be applied thereto which signal is responsive to the precipitator voltage. A resistor may be associated with the capacitor in the unit 9 which resistor is arranged to be short-circuited when the precipitator is first switched on, the short-circuit being removed at the first operation of the trigger circuit 22. Thus, the operating condition of the precipitator is rapidly reached.

Filed: 1973-11-27
Abstract: 1422038 Television distribution systems OAK INDUSTRIES Inc 27 Nov 1973 [29 Jan 1973] 54962/73 Heading H4R Subscription TV receivers require authorization signals from a central unit to enable the transmitted TV signals to be usable, the transmission and receipt of the authorization signals being synchronized via a common mains power supply. A subscriber (e.g. in a hotel) telephones his request to receive a subscription programme and his address is set up in a memory (38, Fig. 2, not shown) at the central unit. The central unit transmits start pulses to initiate counting of mains derived clock pulses (e.g. at 120 Hz) at the central and subscriber stations. When the count at the central station matches the subscriber address an authorization pulse is transmitted and, at the particular subscriber station, this coincides with the subscriber count, thereby enabling for 1 minute a converter which shifts the TV signals to a usable band. Repetitive authorization is necessary for continuous viewing. The authorization signals may be FSK modulated on 111 and 109 MHz carriers.
