Title: Electronic timepieces
IPC: G04G5/00
Filed: 1976-12-23
Abstract: 1536709 Electronic timepieces DAINI SEIKOSHA KK 23 Dec 1976 [29 Dec 1975]  53944/76 Heading G3T A digital electronic timepiece has hours, minutes and day of the week display portions and a display portion for selectively indicating either the date or seconds. Setting arrangements are provided, seconds being automatically displayed when a time of day correction is effected; 12 hr or 24hr mode is selectable and AM/PM indication accordingly. Any or all display portions may be caused to flash when battery voltage is too low. The timepiece Fig. 1 comprises a crystal controlled oscillator, frequency divider 45, level shifter 46, frequency divider 49, seconds counter 50. Counting circuits 53, 61, 62, 70, 78 are used in 12 hr mode operation and 54, 63, 71, 79 in 24 hr mode operation. The operative mode is determined by state of a flip-flop 20 controlled by switches 3 and 4. Each counter in a set is connected to a succeeding counter via a respective electronic switch. Electronic switches selectively couple the counters to respective decoder/drivers 56, 65, 73, 82 to operate mins, hours, day display devices 57, 66, 74 respectively. Display device 83 will receive the secs or date count value via switch circuit 81 and decoder 82, depending upon the position of a manual switch 1 acting on a flip-flop 35. Setting A switch 2 functions as a safety and reset switch. A switch 3 selects digits to be corrected, a shift register 18 receiving a shift pulse each time switch 3 is closed. In normal operation of the timepiece the register output N is at "H" level. If switch 3 is then closed, the "H" level shifts to output DM the other outputs being at "L" level. Therefore only the date will be displayed. To advance the date, switch 4 is operated, a pulse being applied via electronic switch 76 to the date counter 79 each time switch 4 is closed. The mins and hours counters are similarly selected by switch 3 and corrected by switch 4, the respective display being advanced by one unit each time switch 4 is closed. Battery condition indicator A battery voltage detector circuit 36 operates once per day, as it is controlled by AM/PM counter 62. If the voltage is low circuit 36 sets a flip-flop 37 so that NAND 42 passes inverted signals from seconds counter 50 to control terminals of decoder/drivers 56, 65, 73, 82 causing the display to flash. Testing A terminal 48 is provided whereat a high frequency can be injected to the timekeeping circuit for testing. A terminal 85 is provided at which an "H" level signal may be applied whereby all the counters are set to a predetermined time. Thus the displayed contents become 59 sec 59 min 23.00 hrs Sat 31st. After the elapse of 1 sec they will become 00 sec, 00 min, 00 hrs, Sun 1st confirming that the counters are operating satisfactorily.

Title: Alternating-current regulators
IPC: G05F1/445
Filed: 1969-11-24
Abstract: 1,254,234. Control systems for incandescent lamps. SIEMENS A.G. 24 Nov., 1969 [25 Nov., 1968], No. 57466/69. Heading H2H. [Also in Divisions G2-G3] An alternating current regulator for controlling the supply to a lamp load L comprises a  Triac pl whose firing angle is determined by a control unit consisting of an RC circuit r11, C5 which fixes a maximum firing angle and a voltage divider r8, r9, r10 which fixes a minimum firing angle, the divider being connected to atransistor p2 whose impedance is controlled so that the firing angle; during an initial period. following energization of the load, is progres-  sively advanced to provide a gradual build-up of the load current to a value set by the divider adjustment. To this end the current is sensed by a current transformer tl whose secondary winding t12 charges a capacitor C2 which, with components C1, r3 and n5, determines the control current supplied to the base of transistor p2. When the load is first switched on transistor p2 is in its minimum impedance condition and the firing angle is determined by the resistor r 11. The current in each successive half cycle progressively reduces the control current to the transistor p2 to advance the firing angle, such advance being linearized by charging of a capacitor C4, Fig. 2 (not shown) and terminated by a diode n14 becoming non-conductive. Provision of components C3, n10, n11, n12 enables the regulator to limit the load current to a desired maximum value set by the Zener diode n10, If this value is exceeded the impedance of transistor p2 is reduced to retard the firing angle for the duration of the excess, Fig. 3 (not shown), after which capacitor C3 discharges through resistors r4, r5 to restore the firing angle to the value set by the divider r8, r9, r10.

[Also in Division C7] A photovoltaic cell comprises an N-type sintered body 10 of cadmium sulphide, having thereon a layer 11 of P-type material comprising copper, cadmium and sulphur. The layer is formed electrochemically by immersing the body 10 in an aqueous solution of cupric sulphate of concentration >0À1%, and passing a current, preferably of density 0À05-5À0 mA/ sq. cm., between the body as cathode and an immersed copper plate as anode. The P-type layer so formed is 1-100Á thick, and comprises a cadmium sulphide-like structure accompanied by a copper sulphide structure. Examples are given in which solution concentration and temperature, and current density and treatment time are specified. The body 10 may be initially formed as a plate of compressed powdered cadmium sulsulphide of 1-5 or 2À0 mm. thickness, sintered in an inert atmosphere at 750-950‹ C. to provide an N-type body of density >4À6 gm./c.c. and resistivity <10 ohm. cm. One face is then lapped and etched with dilute aqueous HC1, and the electrochemical treatment described above is then carried out, the remaining surfaces of the body being protected by a resin. After formation of the P-type layer, the body may be heated to 150-250‹ C. for 1-10 minutes in air, and then quenched to room temperature, this procedure having the effect of improving the device characteristics. A grid-like electrode 14 of silver is then painted or vacuum-deposited on the P-type layer 11, on which light is intended to be incident. The back face of the body 10 is, after removal of the resin by polishing, provided with a nickel electrode 13 by electroless plating. Leads are then soldered to the two electrodes.

Abstract: 1,200,400. Signalling apparatus for lifts. CKD PRAHA OBOROVY PODNIK. 24 Dec., 1968, No. 61380/68. Heading B8L. [Also in Division G4F. Equipment for signalling in an on/off manner from a lift cage to the motor room and including means in the cage to indicate that the signal has been received comprises an oscillator V producing positive and negative pulses at audio frequency which are coupled by a transformer T v  to the loop comprising suspension cable L 1  and balance cable L 2 , means in the cage to alter the impedance of the loop, a receiver P to detect the pulses and to produce a voltage at N when the impedance is changed, which voltage changes the frequency of the pulses, and a loudspeaker R in the cage to give audible indication of the change in frequency. The impedance is changed in either the positive or the negative direction depending on whether contacts A in cage K 1  or A<SP>1</SP> in cage K 2  are opened by signalling switch S or S<SP>1</SP>. First pressure on these switches opens contacts B, B<SP>1</SP> to bring the speaker into circuit, which thus produces the normal tone. The receiver P includes a polarity sensitive element D which operates either electronic switch E 1  or E 2 . These actuate acoustic and optical indicators Z 1  or Z 2  and also produce the voltage at N for changing the frequency and operating a recorder Z 3 . Thus the tone from the speaker changes only when the signal has been properly received. The oscillator comprises an LC circuit whose frequency depends upon the pre-magnetization of an inductance core by an input voltage.

Abstract: 729,423. Toothed wheels. HUGUENIN, R. A. Nov. 24, 1950 [Oct. 24, 1950], No. 28832/50. Class 80 (1). In order to assist the transmission to the surrounding air or other fluid of the waves of elastic radiation emanating from a toothed gear-wheel due to the internal stresses therein, the faces 15, 16, Fig. 3, of the gear are coated with several linings of materials chosen so that the speeds of propagation through the said linings of the elastic radiation waves decrease progressively from the high speed in the gearwheel material to the low speed in the surrounding air. The linings, which for a steel gearwheel could for example successively comprise copper, tin and lead, are deposited on the wheel faces by coating, dipping, electrolysis, spraying, &c., and a. final porous oil-absorbing layer may be sprayed thereon. The wheel faces may be cupped or otherwise shaped (Figs. 4, 5, not shown) to counteract the centrifugal force on the linings. One or more linings may also be applied to the non-engaged surfaces of the teeth themselves, e.g. by tinning. In addition to the lining process, a gear-wheel may be given a shape such as that shown in Fig. 8 to ensure that opposed faces are non-parallel in order to avoid continued reflection from face to face of those elastic radiation waves in the gear-wheel which are travelling perpendicularly to a face. Alternatively to the Fig. 8 construction, the faces may comprise single oppositely-directed cones, or may have a discontinuous surface provided by a set of radial grooves, or by a large number of recesses formed by a knurling tool. The lining and shaping processes may also be applied to the ends of a gear-wheel shaft, and are applicable to worm, bevel or other gearing.
