Title: Circuit arrangement for driving an electromechanical oscillator
IPC: H03B5/30
Filed: 1971-08-20
Abstract: 1334899 Electronic timepieces ITT INDUSTRIES Inc 20 Aug 1971 [22 Aug 1970] 39152/71 Heading G3T A circuit for driving an electro-mechanical oscillator including a magnet system and a single coil magnetically coupled thereto for relative oscillatory movement the oscillator being for example a balance wheel, a tuning fork or a pendulum in a timepiece, comprises a drive transistor T1 on series with the coil and a diode D across a D.C. source U B , a control transistor Tz and an auxiliary transistor T3. A resistor R3 ensures a steady current through the diode which is said to facilitate self-starting of the oscillator. Voltage induced in coil L by the magnet movement causes T2 to conduct which in turn causes T1 to conduct a drive pulse through the coil-turning off T2 which remains blocked until the end of the drive pulse, T2 is then caused to conduct again since its base becomes more positive than its emitter by the charging of a capacitor C2 and the cycle repeats. The shunting of the diode D by the auxiliary transistor T3 reduces the voltage drop across the diode, which could amount to half the supply voltage when T1 is driven into saturation, T3 being driven into saturation with T1 and by a signal applied to its base via R4. In an alternative embodiment (Fig. 2) the auxiliary transistor is controlled via its emitter, also the diode and coil are transposed. R2 may be dispensed with, a resistor R2 being used instead and connected as shown.

Patent GB-352381-A (GB)
Title: Improvements in method and apparatus for drying clay ware or kindred products
IPC: F26B21/00
Filed: 1929-12-30
Abstract: 352,381. Drying, roasting, baking, &c. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Harrop-Ceramic Service Co. ; 310, West Broad Street, Columbus, Ohio, U.S.A.) Dec. 30, 1929, No. 39727. [Class 34 (ii).] In a method of drying clay or other products, the drying medium is passed through the material within a tunnel or chamber with a spiral and a generally longitudinal movement, the spiral movement being entirely within the chamber. The medium also traverses the material in a tortuous path, a portion being removed at an intermediate point in the tunnel for the subsequent spiral movement. A form of drier for the purpose is shown in horizontal section in Fig. 5, and comprises a chamber 1 through which the material passes on trolleys. The drying medium enters from a duct 2 at the discharge end and takes a tortuous path owing to the staggered pilasters 10. Approximately at the middle of the drier a portion of the medium passes into dampered side collecting chambers 11a whilst another portion rises upwardly through a dampered port 14 into a collecting chamber 16 which also connects with the chambers 11a. A portion of the medium in the chambers 11a, 16 may pass through a stack into the atmosphere and all or a portion may be drawn into a fan 18 and forced into a compartment 19 extending along the top of the drier on one side of it. A series of dampered ports 20 allow the medium to pass into the ware chamber below, where it circulates or escapes through ports 32, Fig. 4, into a compartment 25 parallel with the compartment 19. Once in compartment 25 part may go to the atmosphere through a relief port 26, Fig. 5, or a large part may be drawn back into the fan 18 to be delivered again with medium taken from the chamber 16 or from an outside source or from both into the compartment 19. Pilasters 40, Fig. 6, and arches 41 aid to produce the swirling movement in the medium. The compartments 19, 25 may each be disposed first on one side then on the other of the drier as shown in Fig. 10. In a modification, Fig. 9, the material traverses two main tunnels 27, 28 divided by a partition 29 and one compartment 34 serves to deliver the medium to both tunnels from which it passes into compartments 32, 33 through valves 42, 421.
