Patent GB-460707-A (GB)
Title: A method of, and apparatus for, producing composite x-ray pictures
IPC: A61B6/02
Filed: 1935-06-29
Abstract: 460,707. R÷ntgen ray apparatus. CHAOUL, H., and GROSSMANN, G. June 29, 1935, No. 18702. Convention date, June 29, 1934. [Class 98 (i)] A radiograph of a plane-parallel body layer is produced by employing apparatus for radiographing ar individual plane section of the kind in which the ray-tube and the sensitive plate or film carrier are moved simultaneously during exposure so that the ray through any given point of the body always strikes the plate &c. at the same point and so that the film remains parallel to itself, said apparatus being so modified that the body is continuously displaced during exposure relatively to the moving tube and plate &c. in a direction perpendicular to the bounding-planes of the layer to be radiographed and through a distance equal to the thickness of said layer, in order to produce a record of all the body sections constituting the layer. The apparatus shown comprises an X-ray tube 2 and plate holder 4 mounted on a lever 1 pivoted at 5, the holder 4 being constrained by links (not shown) so that it moves parallel to itself. The pivot 5 is carried by a slide 6 movable in a vertical guide 7 by a screw spindle 8 connected by gearing 12 to an electromotor 13. A toothed sector 9 fixed to the pivot 5 is connected by gearing 10 to an electromotor 11, and the circuits of the motors 11, 13 are both controlled by a switch 14. The position of the pivot 5 in the slide 7 determines the section of the body being radiographed. On closing the switch 14, the lever 1 is rotated into the position 1<1> and simultaneously the pivot 5 is raised through a predetermined distance corresponding to the distance between the aforementioned bounding planes. The switch 14 is opened automatically when the lever reaches the position 1<1>. The displacement of the pivot may be varied by change-speed gearing at 12 or between the spindle 8 and the pivot, or by varying the speed of the motor 13. Instead of raising the pivot, the carrier of the body may be raised by the motor 13. The invention may be applied to apparatus in which the ray focus and plate &c. move in a straight line, circle, spiral &c. in a plane parallel to the layer to be radiographed. The Specification as open to inspection under Sect. 91 states also (1) that the pivot of the member connecting the ray-tube and plate &c. may move stepwise instead of continuously ; (2) that the pivot or the support of the body may be given a pendulum motion; and (3) that radiographs may be obtained in whch successively exposed sections are continuously enlarged or reduced by causing the ray-tube, or the plate-holder, or both to move parallel with the lever in synchronism with the movement of the pivot. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in valve arrangements for the control of the flow of fluids
IPC: F24D19/10
Filed: 1925-07-25
Abstract: 258,052. Willington, W. E. W. July 25,1925. Levels, regulating. - Means for byepassing a heater or other apparatus h through which fluid normally passes, in the event of accumulation of liquid above a predetermined level, comprises two valves a, b arranged in a common stem c connected to a piston o r diaphragm d loaded by a spring e which tends to close the valve a, which controls the inlet to the heater, and to open the valve b, which controls the byepass. The stem c passes freely through a sleeve f which allows the fluid to gain access along the stem to the underside of the piston d, whereby the pressure of the fluid normally holds the valve a open and the valve b closed, so that fluid entering at 1 flows through the heater h and past a non-return valve j to the outlet 2. A passage g leading from the underside of the piston to the heater h is normally closed by a float-operated valve i, and if fluid accumulates in the heater, this valve opens and releases the pressure below the piston d so as to allow the piston to fall; closing the valve a and opening the valve b. The fluid then flows direct through the control fitting and the valve j closes. A hand-controlled release valve l may be arranged in the passage g, and the valves a, b may be arranged on separate stems.

Filed: 1969-04-16
Abstract: 1,255,815. Static inverters; control of A.C. motors. REGUS A.G. 16 April, 1969 [l9 April 1968], No. 19335/69. Headings H2F and H2J' A polyphase inverter or A.C./D.C./A.C. frequency changer structurally combined with an inductive load appliance e.g. an induction motor, comprises a plurality of single phase circuit sections two phases of which are shown in Fig. 2. Each basic single phase section comprises a pair of capacitors 2, 3 in series across a D.C. source 7 which may be variable and a pair of thyristors 4, 5, a load 1 being connected between the pairs which load may be one phase winding of an induction motor. The thyristors 4, 5 are triggered to conduct alternately by a unit 6. With Th4 conducting, current from source 7 passes via a half winding of a commutating choke 12, through the load 1 and charges capacitor 3 while capacitor 2 is first discharged and then charged in the opposite direction. Diodes 10, 11 and resistors 15, 16 serve to limit the charge on the capacitors and to feed back reactive current from an inductive load to the source. When C3 and C2 are chargedcurrent through Th4 ceases so that it turns OFF and Th 5 is triggered ON. C2, C3 will then discharge through the load and Th5, also energy stored in a capacitor 17 will discharge through the choke 12 which produces a blocking voltage across Th4 preventing T4 and T5 conducting simultaneously and causing a short circuit across the D.C. supply. When the capacitors have discharged current through Th5 ceases so that it turns OFF and the cycle is repeated. Alternatively the anti parallel diodes 10, 11 and resistors may be connected to tappings on the load inductor 1. Capacitors may be connected in parallel with the resistors, while in a further embodiment the resistors may be omitted. The inverter may be mounted within an induction motor casing (Fig. 3, not shown). A suitable trigger circuit is illustrated in Fig. 4 (not shown) but is not described. The capacitive components are chosen so that the reactance of the series capacitors balances the inductive reactance of the respective load impedance connected thereto at half the switching frequency.
