Title: Timepieces having time standards constituted by piezo-electric crystal oscillators
IPC: G04R60/00
Filed: 1974-12-04
Abstract: 1487955 Electronic timepieces SUWA SEIKOSHA KK 4 Dec 1974 [5 Dec 1973]  52478/74 Heading G3T [Also in Division G4] Relates to the automatic regulation of an electronic timepiece wherein the output of a frequency divider chain of master slave flip-flops FF 1 -FF 19  Figs. 3a and 3b, fed by a crystal controlled oscillator, controls a transistor bridge T P1 , T P2 , T N  1 , TN 2 to pass drive current pulses through a motor drive coil L 1 . In an automatic regulation circuit the divider portion FF 1 -FF 5  also serves to measure the deviation between the oscillator output frequency and a basic frequency which is locked on to an external standard time signal. When a switch 9 is manually closed (line 12) Fig. 5 at time t 1 , the chain FF 1  to FF 18  is reset and the timepiece is stopped. Transistors T P1 , T P2  T N2  are turned OFF, T P1  is ON so that coil terminal A is at earth potential and coil terminal B will be floating. Coil L 1  then serves to receive wirelessly the external time standard signal. When the external signal is received at time t 2 , the reset on FF 1 -FF 18  is released, FF 1 - FF 5  begin to count the oscillator signal and  master/slave flip-flops FF 20 -FF 24  begin to write in deviation data received from FF 1 -FF 5 . This continues until time t 3  when the next external signal pulse is received, whereupon the writing in ceases leaving in the memory (i.e. FF 20  to FF 24 ) stored data representative of the frequency deviation. At t 3  the dividing circuit is reset again and at t 4  when switch 9 is opened the reset is released and normal operation resumes. In practice, the oscillation frequency of the quartz crystal is arranged to be higher than a nominal value and a precise timing signal is produced by increasing the effective division ratio under control of the regulating circuit. The stored deviation data thereafter in effect controls the running rate of the timepiece by controlling the selective opening and closing of gates A 1 -A 5  to pass correction signals derived from divider stages FF 14 -FF 18  to an Ex-OR gate E 5  via exclusive -OR gates E 1  to E 4  and a NAND gate O 1 , to add to or block pulses from the oscillator circuit. The gate O 1  is controlled by regulation control circuit FF 25 , FF 26  in response to the external signal shaped by diodes D 1  D 2 . The control circuit also resets the divider and controls the writing in of the deviation data, in accordance with the external signal. The stored data may be updated at any time by closing switch 9 to initiate the above described procedure.

Title: Dc power supply
IPC: H02M3/07
Filed: 1970-11-05
Abstract: 1315020 Automatic voltage control INTERNATIONAL BUSINESS MACHINES CORP 5 Nov 1970 [22 Dec 1969] 52608/70 Heading G3R [Also in Divisions H2 and H3] A D.C. power supply comprises a source capacitor 11, an A.C. power input 25-25, a controlled rectifier 28 for charging the capacitor, sequentially operable switches 14A-14D for connecting sink capacitors 13A-13D in a predetermined sequence to the capacitor 11 and sequentially operable switches 15A-15D to connect the sink capacitors to an output load circuit 16, 17 in the predetermined sequence. When, in each half cycle of the full wave rectified A. C. supply to the terminal 25, the gate voltage of a programmable uni-junction transistor 36 in a pre-regulator 10 falls below the anode voltage, which is maintained by a capacitor 35, the transistor 36 conducts. The discharge of the capacitor 35 provides a gating pulse to the rectifier 28 which conducts to enable the capacitor 11 to be charged. The voltage across the capacitor 11 is regulated by a light emitting diode 44 which generates more light if the capacitor voltage increases thereby reducing the resistance of a resistor 43 and decreasing the voltage fed to the trigger circuit for the rectifier 28. The firing point of the rectifier 28 is therefore retarded. A sequencing switch 20 provides sequences of gating signals T1-T4 to 'AND' gates 67A-67D and sequences of gating signals T5-T8 to the switches 15A-15D. The 'AND' gates also receive signals from a voltage regulator 21. The switches 14, 15 are operated at a high frequency and at any instant two of the capacitors 13 are charged from the source capacitor 11 whilst a third one of the capacitors 13 discharges across the load 17. The voltage regulator 21 comprises comparators which compare the voltage across each capacitor 13 with a reference voltage so that when the capacitor voltage equals the reference voltage a signal is supplied to the respective 'AND' gate 67 to open the respective pair of switches 14 and prevent further charging of the capacitor 13 by the capacitor 11. Each of the switches, 14, 15 consists of a uni-junction transistor Fig. 7 (not shown) which controls via a transformer connection, the conduction of a power transistor.

The catheter 12 is frictionally held in a passage 36 of the bushing due to elastic constricting pressure of the bushing on the catheter. The adapter 14 further comprises a nozzle 22 on its front end and the portion 26 of the bore is so proportioned that the bushing is free to move in the rear part and is immobilized due to frictional gripping of the bore at the forward end there of the bushing is inserted into the bore 26 of the adapter and a cannula 38 is inserted into the passage 36 to widen it. The catheter 12 is then inserted in the cannula 38 which is then removed so that the passage reduces in size and the bushing grips the catheter. The bushing is moved to its immobilized condition by pulling the catheter forwards of the adapter or by inserting the fitting to push it forwards. Alternatively cannula may be inserted in the bushing before the bushing is inserted in the adapter.

In the example, benzaldehyde is condensed with malonic acid to form benzal malonic acid, which is added to a sodium hydroxide solution and the resultant salt solution hydrogenated as specified above. The benzylmethyl malonic acid is obtained by acidifying the solution.
