Title: Electronic circuit in a quartz crystal watch
IPC: G04C3/00
Filed: 1975-08-01
Abstract: 1509458 Electronic timepieces EBAUCHES S A 1 Aug 1975 [30 Aug 1974] 32209/75 Heading G3T In an electronic timepiece comprising a crystal controlled oscillator circuit 1, Fig. 1, followed by a frequency divider 4, control logic circuit 5 and driver circuit 6 driving a stepping motor 7, a signal f 1  from an early stage in the divider, e.g. output 8, is conducted to a terminal B of the motor to provide a test point for checking the oscillator frequency. In addition this measurement signal goes from terminal A of the motor (the motor resistance bing relatively low) to a comparator 9 which compares it with a "reading signal" from divider output 10 or derived from the conjunction of several output pulse trains f 1 , f 2 , f 3  from the Q outputs of the divider flip-flops i, j, k in Fig. 2. The comparator detects the presence or absence of the measurement frequency signal at A between drive pulses to the motor. When a switch 11 is open the measurement signal passes from B to A and the comparator produces no reset pulses to the divider. However with switch 11 closed, terminal A is at the potential + V BB  and the low internal resistance of the battery short circuits the measurement signal. Consequently comparator 9 resets at least the last stage of divider to zero and locks it/them in that state. Thereby the watch is stopped and the time display can be set. In Fig. 2, the frequency divider comprises stages a to w, the input f O  to which is at 32768 Hz. The output of stage o is at 1 Hz. Stages p to s and a corrector 18 divide this frequency by ten; stages t to v divide the result by six so that the output period of stage v is one minute. The Q and Q outputs of stage w alternately open NAND gates 20, 21 each minute. The Q output of stage v permits one pulse/min of the Q output of stage j to reach NAND gates 20, 21. The pulse to arrive at the NAND gate which has just opened will be passed via a respective one of inverters I 1 , I 2  to control a transistor bridge T 1  to T 4  whereby to pass drive current pulses in opposite directions alternately through the motor winding 7. To prevent short-circuiting of the battery if switch 11 is closed when transistor T  1  is conducting, a circuit including transistors T 5  to T 9  is provided such that T9 is driven to saturation and blocks T 1 . The pulse train f 1  from the Q output of stage k is used as the signal to be measured at terminal A or B and is applied to NAND gate 14 (comparator 9 of Fig. 1) together with the "reading" signal which is derived from the conjunction of f 1 , f 2 , f 3 , Fig. 3, (not shown) in NAND gate 12 after inversion in inverter 13. The output of gate 14 is a reset pulse train RES which after inversion at 15 functions to reset stages l, m, n, o to zero and which is applied to gates 16, 17 the outputs of which reset stages p to s and stages t to v respectively. In an alternative embodiment, Fig. 4, (not shown) the motor drive pulse circuit comprises MOS transistors.

Abstract: <PICT:0875907/IV (a)/1> A solid urea-formaldehyde fertilizer is made from an alkaline liquid mix of urea and formaldehyde wherein the mol ratio of urea to formaldehyde is greater than 1 by acidifying said mix to a pH value of from 2,0-4,0 to catalyse polymerization and immediately introducing said acidified liquid mix on to a continuous elongated moving surface to promote the formation of a urea-formaldehyde polymer layer not greater than one half-inch thick, maintaining the temperature of said polymer layer between 40 DEG  and 58 DEG C. on said surface during reaction, removing said layer from said moving surface, neutralizing said removed layer, and drying said neutralized layer.  The reaction may be effected in the presence of a non-ionic surface active agent, e.g. polyethylene glycol, polyalkylene glycol and a condensate of an alkyl phenol with an ethylene oxide ether.  In an embodiment of the invention, a solution or liquid mix of urea and formaldehyde maintained at a pH of 7-9 in tank 11 is pumped through 15 and mixed with sulphuric, nitric or hydrochloric acid supplied from tank 16, the resultant mixture being fed on to a moving belt 21 and passed through a heat control system, the resultant film being removed by a doctor blade 27, neutralized in 29 with ammonia gas fed from tank 30 and dried in 32.

Abstract: 755,970. Hydraulic jacks. BALME, R. Nov. 30, 1954 [Dec. 1, 1953; Feb. 26, 1954; July 31, 1954], Nos. 33297/53, 5655/54 and 22415/54. Class 78 (3). A fluid-actuated step-by-step jack for raising shuttering along a column c comprises a cylinder A, a piston D and a pair of spring-loaded dish-shaped gripping rings E, g<SP>1</SP> which are alternately engaged with the column, when fluid is fed into and exhausted from space X, so causing the jack to climb the column and raise the shuttering (not shown) which is secured to flanges a. The rings E, g<SP>1</SP> each comprise a plurality of segments having serrated inner faces. In operation, on introduction of fluid into space X first the piston D is forced downwards until ring E engages the column whereafter the pressure exerted on a ram B secured to the cylinder releases ring g<SP>1</SP> and raises the cylinder until it reaches a position in which the piston abuts against a distance piece J. Space X is then opened to exhaust so causing spring G<SP>1</SP> to release ring E, engage ring g<SP>1</SP> and raise the piston until the piston rod D<SP>1</SP> engages the end of a recess b<SP>3</SP> in ram B. The jack is then ready for a further stroke. The jack may be reversed end for end on the column whereby the above cycle draws the rod upwardly through the jack. In modifications described in the Provisional Specifications only, the gripping rings are laminated, and the jack has provision for oscillating the shuttering to prevent adhesion, and means for varying its stroke.

A circuit for measuring the frequency response of a device X has a test signal oscillator 1 controlled by a sweep generator 4 which produces a signal of varying frequency which is passed through the device X, rectified, amplified and fed to an oscilloscope 2 which also receives the sweep generator output; frequency marks are produced by modulating the test signal oscillator output with a variable reference oscillator 5 and passing the resulting difference frequency signal through a filter so that a reduced signal is obtained when the test signal has a predetermined value, and the filtered difference signal is displayed as a band 9 having a narrowing at a frequency determined by the reference oscillator setting. The displays 3 and 9 may be combined as at 11. In another embodiment the C. R. T. is scanned vertically and horizontally as in television, but with vertical lines, deflection signals are obtained from the sweep generator 4 as before. Comparator circuits compare the signals from the test device X and the frequency marker circuit with the vertical deflection signal and the C. R. T. beam is switched on when the instantaneous amplitudes are equal. The two displays may be combined, as before, and a single comparator used to compare the vertical deflection signal with the combined signals from the test device and marker circuit. Additional frequency marks from the other sources may be added to the display.

Dec. 1, 1933, No. 33703. Convention date, Dec. 2, 1932. [Class 40 (v).] A short-wave adapter designed to cover wave-bands between 5 and 120 metres is characterized by the use of a combined detector, oscillator and mixer valve 1, backcoupled through the oscillatory circuit 8, 9 and the inherent valve capacities. The resulting beat frequencies are fed through the amplifier 18 to the input 63 of a standard broadcast receiver. The aerial is coupled to the oscillatory circuit 8, 9, across the anode and grid, by a small condenser 12 to reduce the effects of aerial capacity. The anode and grid resistances 6, 7 are of the low-capacity type and are preferably enclosed in the bulb of the valve 1. The intermediate-frequency is passed from the coupling-resistance 6, condensers 11, 16 and choke 20 to a tuned circuit 38, 40 across the grid and cathode of the amplifier 18. To prevent the oscillation frequency from leaking back into the aerial, the input arrangement shown in Fig. 2 may be used in which the moving plates of the condenser 50 are directly connected to the aerial whilst the fixed plates are across the oscillatory circuit 8, 9.
