Title: The process of fabricating magnetic circuit devices
IPC: H01F10/28
Filed: 1962-11-07
Abstract: A magnetic storage element is made by electro-depositing copper as a fine grain random orientated coating on phosphor-bronze or beryllium copper substrate, preferably in the form of wire, and plating a ferromagnetic coating on the copper, preferably Fe/Ni alloy having a square hysteresis loop.  The wire 2-50 mils thick is preferably cathodically etched in alkali solution, treated with acid and washed before plating in an acid copper sulphate bath at 227 A.S.F. for one minute.  The grain size of copper so plated is 0.1-1 m .  A plating bath containing FeCl3, NiCl2, ammonium chloride and citrate, and a trace of ammonium hepta molybdate is used at pH 8.6, temperature 90 DEG C.  Twistor type devices may be made, when the wire is drawn continuously at constant speed and minimum tension, and centrally disposed in a helical anode of molybdenum wire. Specification 896,263 is referred to.

Title: Alarm electronic timepieces
IPC: G04G15/00
Filed: 1976-10-11
Abstract: 1523948 Electronic alarm timepieces DAINI SEIKOSHA KK 11 Oct 1976 [13 Oct 1975] 42173/76 Heading G3T An electronic timepiece is provided with alarm means (aural and/or visual) which can be set to operate when a pre-set alarm time is reached, either for a single brief period e.g. 10 seconds or continuously until manually switched off. In either case, the alarm may be of an interrupted nature. In Fig. 2, a NOR gate 30 in a coincidence circuit 8, produces an output signal when the actual time counted by minutes and hours counters 4, 5 respectively, coincides with the alarm time pre-set into minutes and hours memory counters 6, 7 respectively. The coincidence signal is converted into a short pulse by a shaping circuit 15; which pulse sets a flip-flop 40, 41 in an alarm drive circuit 14, causing a NAND gate 42 to pass a 32 Hz signal derived from a seconds counter 3. Thereby a transistor 43 is caused to pass 32Hz current through an alarm sound generator coil 15, producing the alarm. If an alarm mode selector switch SW  1  is in a position whereat the output of a flip-flop 16 is logic "I", a self-terminating alarm is initiated when the set time is reached and an AND gate 31 output signal resets the alarm time counters 6, 7. The alarm is automatically terminated at the end of the period (e.g. 10 seconds) determined by a delay circuit 171. If switch SW 1  is in a position whereat the flipflop 16 output is logic "O", the counters 6, 7 will not be reset when the alarm time is reached, and the alarm will continue until manually switched off. The output of flip-flop 16 also controls a drive circuit 17 connected to display elements S 1 , S 2  to indicate which alarm mode has been selected.

Filed: 1968-09-06
Abstract: 1277205 Programmed electric control THORN LIGHTING Ltd 28 Aug 1969 [6 Sept 1968] 42639/69 Heading G3N A control system particularly for stage lighting comprises a number of stores selectively connectible to a control store in such a manner that the control store may control any of the number of stores, and in another selection mode of any one of the number of stores may control the control store. The count in the stores is changed by, or may reposition, a mechanical input device. A fader F has a manually operated arm L coupled to a shaft SH1 driving a rotary potential divider which provides a signal to an error detector ED receiving in sequence through continually rotating switches S22, S23 a signal from each of stores OS1-3. A switch S3 through a further rotating switch S23 selects which store will be connected. In position A of a switch S11 the error detector drives a motor M to set the potentiometer so that its output corresponds to that on line 60. In position M the reverse condition applies and the stores OS1-3 are adjusted to correspond with the potentiometer output. A delay may be incorporated to avoid selection of any store until this has been aligned. Switch S11 may be operated by a relay responsive to finger contact on lever L e.g. by means of a conductance or capacity sensitive detector. A circuit may be incorporated to prevent the lever L being driven backwards spuriously. A clutch may be placed in the shaft SH1 to disconnect the motor when the lever L is moved manually, which clutch may be disengaged by the detector circuit. The arrangement is stated to be suitable for use with the systems described in Patent Specifications 1171914/5/6. The signals may be in digital form. In Fig. 7 (not shown) each of 400 signals in a core store (CS) are read in sequence into a buffer store (BS) and written back with a new value if applicable. A digital/analogue converter produces a signal corresponding to the count, at each instant, in the buffer store which is distributed through a scanner (S21) to lamp dimmer control circuits.
