Title: Improvements relating to hydraulic cushions for sheet metal drawing, or cupping, and like presses
IPC: B21D24/02
Filed: 1932-02-18
Abstract: 392,305. Cupping. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Marquette Tool & Manufacturing Co., 6500, West 65th Street, Chicago, U.S.A.) Feb. 18, 1932, No. 4785. [Class 83 (iv).] A hydraulic cushion for cupping and like presses has the inflow and outflow of the fluid controlled by a single valve, fluid pressure means urging the valve to the closed position in the working stroke, and opening the valve at a predetermined point in the cycle of operations. The valve comprises a member 32 seating in a recess 34, and having apertures 37 to permit the passage of fluid from a tank 30 beneath the piston 23 when the valve is unseated. The valve is connected to a piston 39 operated by fluid pressure controlled by a valve 43 having an integral arm 48 adapted to be rocked by arms 53, 54 on a link 50 reciprocated from the press-actuating mechanism. During the descent of the die 26 and piston 23, fluid from the tank 30 is trapped beneath the piston and acts as cushioning means therefor, the pressure being determined by that tending to keep seated the valve 32. On the upstroke, the valve is opened after an interval to admit fluid beneath the piston 23. The Specification describes also the construction of Specification 392,502 and the means by which it may be converted to the form of the present invention.

Title: Improvements in and relating to dynamo electric transmission gear
IPC: H02P7/34
Filed: 1930-02-12
Abstract: 355,270. Transmitting mechanical power. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- Maschinenfabrik Augsburg-N³rnberg Akt.-Ges. ; Nuremberg, Germany.) Feb. 12, 1930, No. 4797. [Class 38 (iv).] An electrical transmission gear of the type where the generator armature a, as shown in Fig. 1, coupled to the prime mover shaft k, and an intermediate rotating member is coupled to the driven shaft w and carries the generator field magnets b and motor armature d, and a stationary member carries the motor field h, is shown in Fig. 2 with the motor field winding h connected in series with a battery c and the field h and battery connected in parallel with the generator field b. The voltage applied to the motor field winding is thus equal to the difference between the battery voltage and the drop across the winding b. The drop across the field b decreases as the vehicle speed increases and when the drop is less than the battery voltage the field h reverses. The voltage generated by a, b drops and the motor d, h generates, creating a braking torque. Automatic variation of the motor field according to the resistance of the vehicle to motion is thus obtained.

Filed: 1940-03-19
Abstract: 539,798. Clocks. HORSTMANN, B. G., and HORSTMANN GEAR CO., Ltd. March 19, 1940, No. 5103. [Class 139] [Also in Groups XXIX and XXXVII] Power transmission mechanism for valves and electric switches comprises two sources of power transmitting unidirectional drive through transmission trains to a driven member, an antioverrun device being incorporated in at least one of the transmission trains for preventing the driven member from overrunning its drive. As shown, applied to a time-control device adapted to operate valves or switches, a driven member 18 may be driven either by the pinion 8 of a syncronous motor or by a clockwork motor having a going barrel 3. The pinion 8 gears with a disc 7 carrying a ring 11, the cylindrical inner periphery of the latter engaging three toggles 12 pivoted to a plate 13 and thus driving a plate 14 fast on the shaft 15. A disc 16 fast on the shaft 15 transmits the drive to a disc 19 fast on the member 18 by means of a pin 17 working with slight clearance in a slot 20. When the clockwork motor is driving, the drive from the going barrel 3 is transmitted directly to the disc 19 by a toggle 22 which is pivoted to the disc 19 and engages the inner cylindrical periphery of a ring 21 secured to the casing 3. To prevent overrunning of the member 18 whatever source is driving, a toggle member 24 is provided. This is pivoted at 23 to the disc 19 and has a circular end snugly engaging a portion 26 of a slot 25 in the discs 16. When the member 18 tends to overrun the end of the toggle 24 jams against the inner periphery of the ring 21. This jamming is caused by the pivoting of the toggle about the slot part 26 and is permitted by the relative movement between the discs 16, 19, allowed by the pin and slot connection 17, 20. The final gear 6 of an escapement train may mesh with teeth 5 on the barrel 3.

Abstract: 1,138,994. A/D converters. STANDARD TELEPHONES & CABLES Ltd. 3 Feb., 1967, No. 5312/67. Heading G4H. The logarithmic characteristic of a coder of the type in which a PAM sample excites an oscillatory circuit subjected to non-zero damping so as to successively switch a trigger circuit until the amplitude of the oscillation falls below the trigger threshold-level, is modified by making the threshold-level time variant. In one embodiment, the trigger circuit T 1 , T 2  is supplied at the base of T 1  with the damped oscillation and at the base of T 2  with a threshold-level of the form a(t)=K(1-e<SP>-2αt</SP>) obtained by the charging of a capacitor C. It is shown that such a varying threshold-level results in an overall sinh<SP>-1</SP> characteristic passing through the origin. In another embodiment, the logarithmic characteristic is linearized piecemeal, the first linear portion passing through the origin, and in this case the threshold-level is of the form a(t)=Xte<SP>-αt</SP> for the first linear portion and a(t)=(X+Yt)e<SP>-αt</SP> for succeeding portions. These threshold-levels are supplied by critically damped LCR circuits excited by a constant voltage source and by ramp voltages superimposed on constant voltage sources.
