Title: Improvements in electric circuit breakers
Inventor: BAGNALL ROBERT IRONSIDE
IPC: H01H73/44
Filed: 1950-04-06
Abstract: 693,913. Automatic circuit-breakers; protective cut-out arrangements. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd. April 6, 1951 [April 6, 1950], No. 8668/50. Class 38 (v) In a circuit-breaker having contacts normally maintained in the closed position by toggle links, the links are "broken" to produce tripping on the movement of an armature by a constant magnetic field, the initial movement of the armature into the effective range of the magnetic field being effected by an overload trip device or by an earth leakage trip device. The circuit-breaker comprises a bridge piece 14 on a carrier member 13 which is pivoted at 18 to the base 11 and connected by toggle links 20, 21 to a spring-biased operating plunger 23. When the circuit-breaker is in the "on" position, the toggle links 20, 21 are slightly overset and exert a substantially lateral thrust on the plunger 23 to retain it in the "on" position and the bridge piece 14 holds contacts 16 on springs 15 in engagement with fixed contacts 17. A pivoted armature 30 is normally disposed just outside the effective field of a permanent magnet 31 and has laterally-extending parts 303 which may be engaged by plungers 43, 53 of an earth leakage solenoid 37 and an overload solenoid 44. Under fault conditions the appropriate plunger 43 or 53 moves the armature into the field of the magnet, which then displaces the armature 30 sufficiently for an upturned part 301 thereof to strike the end 213 of an arm 212 of the toggle link 21 to "break" the toggle 20, 21. The resilient springs 15 open the contacts 16, 17 and the spring 25 forces the plunger 23 up into the off position, this movement straightening and resetting the toggle. The carrier 13 abuts portions 302 of the armature 30 and restores it to its initial position. The switch may be tripped manually by depressing a button 34 which engages a short extension 201 of the link 20 to break the toggle. The earth leakage trip 37 may be tested by the depression of a push-button 58 which moves a spring blade contact 55 out of engagement with a fixed contact 57 into engagement with a contact which is connected through a resistance 56 to a main supply terminal. The overload trip 44 may have opposing coils 49, 51, the coil 49 being in circuit with a resistance 50. The parallel circuits formed by the coil 51 and the coil 49 and resistance 50 have different temperature coefficients so that under overload conditions the change in the distribution of the currents in the coils causes operation of the overload trip with an inverse time delay, as disclosed in Specification 680,336.

Abstract: 268,800. Treuhand-u. Revisions-Akt.-Ges., (Assignees of Pleissner Sohn, 0.). March 31, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Variable-speed epicyclic gearing comprises a double clutch 8 by which sun gears i, h can be clutched alternatively or simultaneously to a driving-shaft a, A loose casing c carries planet gears 1, 2, 3 meshing with the gears h, i and with a gear l, which, in the simplest form, is fast on a driven shaft 4. When the casing c is held by a brake 5, two different forward speeds are obtained by clutching the gears h, i alternatively, and when the casing is freed, a solid drive is effected by the simultaneous clutching to the shaft a. A further ratio, which may be a reversed drive, is obtained by holding fast the gear h by a brake 6 applied to a drum d. In the arrangement shown in Fig. 1, the gear l and another gear k are loose with respect to the driven shaft 4, and a second double clutch 9 and brake 10 provide for a further range of speeds. The clutch 8 comprises bands g, r, Fig. 2, which may be expanded and contracted respectively into engagement with clutch drums d, e by the longitudinal sliding of a two-part sleeve m, n, Fig. 1. The separately-movable sleeve parts m, n carry pins engaging slotted cranked levers p, p<1>, which through spring links x, z and bell-crank levers t, t<1> apply the clutch bands. The links x, z, which may be of the alternative forms shown, allow the levers p, p<1> to be moved to locked dead-centric positions with one or both clutches applied.

Title: Improvements in or relating to machine guns or the like
IPC: F41A9/68
Filed: 1917-06-22
Abstract: 191,755. Low, A. M. June 22, 1917. Machine guns centrifugal. Relates to guns of the type in which the projectiles are fed from a magazine into the path of a projection or striker on a rotating disc. According to the invention, the projectiles are fed into the breech end of the barrel, through which the striker sweeps at each revolution of the disc. The disc 1 is rotated on ball bearings 4 in a supporting frame 8, 9, the upper part of which carries the breech end 14 of the barrel (not shown). The projectiles 19 are carried in the superposed compartments 18 of a magazine 20 which, by operating a hand-lever 30, is lowered step-by-step in a casing 27 to bring each compartment in turn into line with a lateral opening in the breech 14. The contents of a compartment are fed into the breech by a spring 24 acting on a plate 21. The lever 30 has bell-crank arms 28, Fig. 5, on each side of the casing 27, which arms on being moved to the left turn about pivots 29 and, after withdrawing the plate 21, move the magazine, down one step by means of spring strips 32 which engage teeth on the sides of the magazine. The magazine is retained' at each step by spring- controlled balls 40 arranged in housings 38, the balls being locked in recesses in the sides of the magazine by the action of wedge surfaces on rods 36 moving with the levers 28. To prevent the first projectile being fed to the breech before the striker passes a definite position, a blocking sleeve 42 is pressed forward against the action of a spring 47 and held by a detent 46 mounted on a pivoted trigger 51 which is pressed into the path of the striker 11 by pushing forward a rod 49. In a modification, electromagnets are employed to control the feed of the projectiles to the breech.

Title: Improvements in or relating to the making of flexible joints
IPC: B25B27/28
Filed: 1935-03-22
Abstract: 433,605. Flexible - unjointed hinges. ANDRE (SILENTBLOC), Ltd., and HUTTON, P. C., Victoria Gardens, Ladbroke Road, Notting Hill Gate, London. March 22, 1935, No. 9019. [Class 65 (ii)] In the assembly of a joint comprising inner and outer cylindrical members with a rubber or like bushing compressed between them, the bushing B being first inserted in the outer member A and the inner member D (shown as a sleeve), being then inserted in the bushing B by means of a mandrel C, sliding of the bushing B on the member D is avoided by accommodating the greater part of the member D in a bore in the tail C<1> of the mandrel ; the bushing slides over the mandrel until a part of it grips the projecting portion of the member D, which then remains stationary while the mandrel moves on and leaves the bushing in position on the member D. This method of assembly is particularly applicable to joints having an inner member with a corrugated or other rough surface which would prevent relative sliding of the members B, D. The first part of the operation is performed by pressure on a rod E bearing on the end of member D, and after the member D has stopped moving owing to the grip of the rubber the mandrel C continues under its momentum; this movement may be assisted by slightly tapering the mandrel towards its rear end to facilitate the passing off of the bushing. This method may be employed where the insertion of the sleeve is performed in two stages as described in Specification 433,604.
