Title: Electronic timepiece
IPC: G04G3/02
Filed: 1975-05-12
Abstract: 1470135 Electronic timepieces DAINI SEIKOSHA K K 12 May 1975 [14 May 1974] 19880/75 Heading G3T In the regulation of an electronic timepiece comprising a crystal controlled oscillator 11, Fig. 2, a frequency divider counter 12 and a counter 16 for driving a time display, any drift in the oscillator frequency is periodically compensated for by changing the effective division ratio of the divider 12 under the control of a circuit 17 and a pre-set circuit 18 including a memory 14, a setting circuit 15 and a control setting circuit 13. The memory 14, e.g. a counter, memorizes the number of switching operations of a manually operated switch S; for example after three switching operations the output state of Q 11  to Q 14  becomes 1100 and this is applied directly and via inverters I 3  to I 6  to respective gates G1 to G8 together with signal S from circuit 17. Outputs Q 21 -Q 24  of the divider 12 are pre-set to 0011 when the signal S is a logic level "O" whereupon S changes to logic "1". The subsequent three pulses from oscillator 11 sets the divider outputs Q 21  to Q24 to 1111 whereupon a gate 19 produces an output pulse to counter 16. The fourth pulse from the oscillator resets the divider outputs to 0000 and the cycle repeats. The oscillator 11 continuously applies pulses to divider counter 12 and the output O 1  of counter 16 produces a timing signal for time display, while its output O 2  is an adjustment signal which changes output S of circuit 17 to logic O and the complement 0011 of the memory content again pre-sets outputs Q 21-24  of divider 12 to 0011. Accordingly, if the adjustment signal O 2  is produced at the end of T seconds from the instant when the oscillator output is first applied to divider 12, the dividing ratio will be changed every T seconds. The number of switching operations is determined by the amount of adjustment required.

Title: Improvements in and relating to magnetic separators
IPC: B03C1/12
Filed: 1924-08-25
Abstract: 236,758. Thompson, H. H., Davies, A. E., and Box, W. E. Aug. 25, 1924. Magnetic separators.-In a separator pulley, magnet windings d, Fig. 1, in the form of separate units are carried on cores e arranged longitudinally between steel or other rings c which are mounted on and carried by the stepped peripheries of rings b, of brass or other non-magnetic material, secured to a shaft a. The spaces between the outer edges of the rings c is filled with strips of brass or other non-magnetic material, secured to shoulders g on the rings c to provide a smooth surface for the pulley belt. To ventilate the pulley, air enters the latter through apertures j in the strips f and leaves by apertures (not shown) in the rings b. The circulation of the air may be assisted by a fan rotatably mounted on the shaft a. In a modification, Fig. 5, spiders m of non-magnetic material are mounted on a stationary shaft a. Segmental pole-pieces w which extend for slightly more than 180‹ and carry the cores &c. o mounted on the spiders m. The cores c &c. are mounted inside a rotary dum k having a non-magnetic periphery q. The poles n may extend beyond the cores o or an adjustable armature may be arranged close to the drum to concentrate the lines of force. In another modification the pole pieces are provided with inwardly, directed or cranked flanges, the space between the poles being closed by a non-magnetic strip. The surfaces of the flanges may be serrated, grooved or, ribbed. When this form is used with a drum, as in Fig. 5, the non- magnetic periphery is provided with a groove fitting between the flanges of the pole-pieces and into which the material to be treated is fed. Continuous or broken rings or bars, or studs or feelers of magnetic metal may be secured on the outer surface of the drum. Specification 5522/07 is referred to.

Title: Improvements in and relating to television and like systems
IPC: H04N5/16
Filed: 1935-07-12
Abstract: 459,853. Television. WHITE, E. L. C., 32, The Rise, Hillingdon, Middlesex. July 12, 1935, No. 20022. [Class 40 (iii)] Signals, which have been distorted by passing through a channel with a low-frequency cut-off, cause a reactance 5 to assume a charge dependent on the peak amplitudes (synchronizing signal) in the signals, and changes in the charge on the reactance control electric variations which are mixed with the distorted signals to compensate changes in the general tilt of the potential curve of the signals which occur at a sudden change in average brightness, Fig. 1 (not shown). A synchronizing signal overcomes the grid bias due a circuit 3, 17 and causes valves 2, 4 to conduct. When the level of the tips of the pulses change, a charge is given to the condenser 5 which maintains the potential of the cathode of the valve 2 between pulses. Changes in the potential across the condenser 5 cause charging or discharging of a condenser 8 through a valve 6. The potential variations across the condenser 8 are reversed by a valve 9, and fed to an amplifier 12 in parallel with a valve 10, which amplifies the original signals. Since the compensating variations commence only after an interval of one line period, the signals are fed to the valve 10 through a delay network 16. The direct-current component is reinserted as described in Specification 422,906 or 449,242.

Filed: 1976-05-04
Abstract: 1484399 Annealing ion-implanted semiconductors STANDARD TELEPHONES & CABLES Ltd 4 May 1976 [13 May 1975] 20075/75 Heading H1K An ion-implanted compound semi-conductor body is annealed in an atmosphere containing the constituent elements of the semi-conductor under conditions such that the atmosphere is in substantial thermal equilibrium with the body. Since in practice exact equilibrium cannot be achieved it is necessary, e.g. for a GaAs body (e.g. S-implanted), to encapsulate the body in SiO 2 , which prevents loss of As at the annealing temperatures, Ga (which penetrates SiO 2 ) in the atmosphere preventing salt loss from the body. The atmosphere may also contain the implanted dopant under conditions which prevent outdiffusion from the body. Various practical arrangements for performing the annealing are disclosed.
