Abstract: 493,926. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 8, 1937, No. 620. Void. Convention date, Jan. 13,1936. [Class 38 (ii)] Grid control impulses for a discharge device are produced by means of a cathode-ray tube which has in place of the fluorescent screen a ring of electrodes over which the ray is deflected either electrostatically or electromagnetically, the control grids being connected in circuit with the electrodes. To obtain phase shift of the grid potentials the ray deflecting system may be rotated mechanically. Alternatively the phase position of the rotating field may be altered by adjustment of the components producing it. Grids may be provided to give control of the magnitude of the impulses. The duration of the impulses is determined by the width of the electrodes. If desired a double ring of electrodes spaced apart may be used so that overlapping may occur. In arrangements where it is desired to have two discharge paths simultaneously conductive, two electron ray systems operating on opposite sides of the ring of electrodes may be used, or two concentric rings of electrodes with the ray spread slightly so as to spread over the two rings may be used.

Abstract: 327,469. Schall & Son, Ltd., and Dunkel, E., Jan. 10, 1929. Supplying and controlling consuming devices.- The primary circuit of an X-ray transformer includes a timing device which when the circuit is closed operates by means of dash-pot mechanism to break the circuit after a predetermined interval. The dash-pot mechanism actuates the control switch of a main magnetic switch in the transformer primary circuit. In one form, Fig. 1, the operation of a switch w closes the circuit from the mains A, B, through contacts u<1>, u<2>, Change-over switch w<3>, w<2>, w' and solenoid h, energizing the latter so that the rod g and piston b of the dash-pot mechanism are raised to the uppermost position. When the pushbutton v is depressed (1) a circuit through switch w, contacts u<1>, v<1>, control switch j<1>, and main magnetic switch k<1> is completed causing the transformer primary circuit m to be closed, and (2) the circuit through the solenoid is simultaneously broken so that the piston b begins to fall in the cylinder a at a rate depending upon adjustable outlet passages c in the cylinder a. An extension j<0> of the control switch is arranged, at a height controlled by a rack p<1> and pinion p<2>, in the path of a disc n fixed to the piston b. When the disc n contacts with the extension j<0> the switch j<1> breaks the circuit through the coil k of the main magnetic switch k<1> which then breaks the circuit of the transformer primary. The switch arm w<2> may be moved to cut out the dash-pot mechanism, the main magnetic switch being then controlled by a foot-switch w<0>.

Filed: 1976-01-12
Abstract: 1511942 Automatic control WESTINGHOUSE ELECTRIC CORP 12 Jan 1976 [20 Jan 1975] 990/76 Heading G3N [Also in Division B3] A repetitively operated punch press is automatically monitored and selectively controlled in response to mechanical vibrations developed during operation. The output of a Piezo-electric accelerometer in a fixed die-shoe is time-integrated during a press-stroke and compared with an arbitrary level. During a "beam" phase the gain of an amplifier for the output of the accelerometer is adjusted in succeeding cycles until the arbitrary level is exceeded. The level is then increased during further cycles until the difference is reduced to a set amount. The increased arbitrary level is then taken as a reference function. During an "auto-control" phase the time integrated output of the accelerometer forms a test function which is compared with the reference function. A first level of comparison indicates a malfunction which requires operator's attention, a second level shuts down the press.

Patent HK-26282-A (HK)
Title: Timepiece movement
IPC: G04C10/00
Filed: 1982-06-17
Abstract: A small sized electric timepiece movement has a radius which is less than the diameter of the battery which powers the movement. Hence, the battery extends from one side of the movement to a point beyond the centerline of the timepiece. Advantage is taken of the fact that the battery is dome-shaped so as to accommodate a portion of the base plate which rotatably supports the cannon pinion and hour wheel of the timepiece movement which are located centrally of the timepiece. Hence, the axis of the cannon pinion and hour wheel, if projected, would intersect the battery. The invention enables the construction of an electronic timepiece which is smaller than would otherwise be possible. With a battery having a diameter of 7.9 mm and a thickness of 3.5 mm, it is possible to make a timepiece having a diameter of 14.8 mm and a thickness of about 4 mm.
