Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1929-05-29
Abstract: 334,219. Automatic Telephone Manufacturing Co., Ltd., and Rice, T. G. May 29. 1929. Automatic exchange systems.- In a bidirectional hunting switch that hunts for the absence of potential, the operation of the switching relay is speeded up by a kick of high voltage supplied by an inductive winding. To ensure the complete operation of the vertical magnet during hunting, the " double-dog " is fitted with springs which short-circuit the interrupter springs when the the " douhle-dog " is fitted with springs which originates A operates removing the normal earth from the calling level in bank VB and from the terminal of the calling line wiped by 44. Relay S energizes, enabling H1 of allotter FA1 (or H2 of FA2) to operate. Relays G and C pull up and a self-interrupting circuit is completed for V to step the switch. The " double-dog springs DD shorting 31 whilst the magnet is stepping. When " off-normal " springs N have operated relay C is held energized from earth on bank VB which earth also short-circuits D. When the unmarked level is reached a circuit is completed for C and D in series to 27 and the high voltage surge from the inductive winding of C enables D to energize quickly and break the stepping circuit. Relay E pulls up and a stepping circuit is completed for the rotary magnet R to step the wipers over the selected level. The off-normal springs RON remain closed until the test wiper reaches the first bank contact. When the calling line is reached wiper 44 fails to find earth and relay F energizes in series with C its speed of operation being increased by the inductive kick from C. The circuit is switched through to the selector, and relay B pulls up releasing the allotter. Relays D, E, and G release, but relays A, B, C, and F are held during the conversation by earth returned over the test conductor.

Title: Improvements in or relating to gyroscopic apparatus
IPC: G01C19/38
Filed: 1932-06-17
Abstract: 401,039. Gyroscopic apparatus. GRAY, J. G., La Mancha, Victoria Circus, Dowanhill, Glasgow. June 17, 1932, No. 17144. [Class 97 (iii).] In gyroscopic apparatus for demonstrating gyroscopic effects or use as an artificial horizon, the sole support for a gyroscope casing is a peg and cup connection with a shaft capable of rotation in either direction so that the gyro axis tends to set itself parallel to or in line with the shaft. In Fig. 2, the gyro casing 6 has an axial peg 5 resting on a cup 4 carried by a vertical shaft 1 which is rotated through gearing 3 by the reversible motor 2. When the axis 1 rotates in the same direction as the rotor, the axis of the latter is erected into alignment with the shaft 1, and when in the opposite direction, the inclination of the rotor axis to the vertical increases. A second gyro casing 61 may be supported by means of a peg 5 in a cup 4 on the gyro casing 6, and a third gyro casing 6<11> may be similarly supported on casing 6<1>. The casing 6 is eccentrically weighted so that when the rotor axis is inclined the casing is prevented from rotating with the rotor and if it does rotate at small inclinations of the rotor axis an erecting effect is obtained. Alternatively the peg 5 may lie to one side of the rotor axis. In a further alternative erectors of the type described in Specification 130,697, [Class 97 (iii), Thermometers &c.], may be attached to the casing 6. Fig. 4 shows a form of erector in which rods 7 terminating in masses 8 are pivoted at 10 on a plate 9 attached to the casing 6 in a plane at right-angles to the rotor axis. A mirror for use as an artificial horizon may be mounted on the casing 6 or on a plate, which carries rigidly two gyroscopes and a peg resting in a cup on a rotatable shaft. A construction is described in which the frame of a small gyroscope with normally vertical axis is pendulously mounted on a normally horizontal axis in a frame fixed on the casing 6 of the main gyroscope.

Filed: 1947-07-01
Abstract: 624,301. Valve gear. SADLER, D. V. July 1, 1947, No. 17261. [Class 7 (vi)] A sleeve valve for a two stroke engine is operated by a crank or eccentric 1, Fig. 1, on a crankshaft 2 through a link 3 engaging one end of a lever 5 connected by a ball and socket connection to the valve 7 and pivoted at 8, the link 3 having a guiding slot 13 cooperating with a block 12 on a pin 11. A pipe 14 conveys oil to lubricate the surfaces of the pin 11, block 12, and slot 13. In a modification, Fig. 3, the lever 5, connected to the link 3, is pivoted at 8 in a rotatable bearing 17 fixed in a slide 15 the bearing 17 being connected by an arm 18, pivoted lever 20, and link 21, to the link 3. As the link 3 reciprocates, the lever 20 is partly rotated about its pivot 11 to reciprocate the slide 15, thereby moving the pivot 8 to increase the rate of opening and closing of the valve controlled ports. In a modification the slide 15 is connected to an eccentric mounted on an auxiliary shaft which is rotated, for reciprocation of the slide, by a connection to the link 3. In a radial engine, a main eccentrically operated link is connected to links operating the remaining valves, all of the links having slots co-operating with guiding blocks. For a four-stroke engine, the cranks or eccentrics actuating the links may be driven from the main engine shaft through two-to-one reduction gearing, or eccentrics mounted on the main shaft may be used with epicyclic reduction gearing.
