Title: Selective relay for the protection of electric lines
IPC: H02H3/42
Filed: 1925-06-04
Abstract: 235,197. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). June 3, 1924, [Convention date]. Cut-out systems; induction relays.-In selective time-lag relays of the induction type which operate in a time dependent on the distance of the fault from the relay and are substantially independent of the applied voltage, the time lag is made proportional to the resistance of the line to be projected by making it proportional to the angular velocity of the relay. Operation is effected by the engagement of the spring contacts i pivoted at e with a stop d of spiral form mounted on the induction disc a which is driven by current and voltage. The flux produced by the voltage being relatively small and that produced by the current relatively large. When excess current flows in the circuit and through the coil f the spring contacts are drawn towards the stop at a constant speed determined by the retarding device h. The time interval before contact is made is dependent upon the speed of the disc which is interlocked with the coil f so that both come into action together. The faster the speed of the disc, that is, the greater the resistance of the circuit to be protected the further is the movement of the spring blades necessary before contact is made. The induction discs in the case of a three-phase circuit may be arranged one for each phase on a common shaft each disc being under the influence of the current of a phase and the voltage of this phase to earth, and the voltage coils may be connected by the current winding only when an excess current occurs in the phase concerned. Specification 214,646 is referred tn.

Patent GB-462505-A (GB)
Title: Improvements in or relating to electric switches
IPC: H01H3/60
Filed: 1936-05-25
Abstract: 462,505. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd. May 25,1936, No. 14710. Convention date, June 13, 1935. [Class 38 (v)] [Also in Group XXXV] In an electric switch having a movable switch element biassed in the opening direction, a stop member is adapted to be engaged by said switch element upon movement under such bias to a given limit, said stop member being movable to permit overtravel of the element beyond said limit and being biassed in such a way that it returns said element to said limit, the stop member being associated with means for retarding its movement in both directions to arrest the switch element in said limit without rebound. As shown in Fig. 2, in an electromagnetic contactor the operating armature 8 is mounted in a pivoted carrier which is connected to the moving contacts by a bar 9. The lower end of the carrier projects downwardly so that when the armature falls back after operation the rounded lower end 21 engages the head 20 of a dashpot piston rod 13. This rod, as shown in Fig. 3, extends through the supporting plate 4 and carries a piston 12 working in the dashpot cylinder 11, a spring 18 bearing on the rear piston face. Thus, on release of the armature it moves rapidly to a limit position, after which overtravel beyond such limit is retarded by air being forced from the rear of the piston to the front through the clearance between the piston and cylinder and also through openings 19 in the piston. The armature is subsequently restored to the limit position by reason of the compression of the spring 18 which occurs during the overtravel movement, this restoring action also being similarly retarded. Thus a frictional dissipation of the kinetic energy of the armature is effected without rebound, the armature being restored to a position in which it will respond to an energizing current of the operating electromagnet 7 of relatively low value. The dashpot is preferably, as shown; of large diameter relative to its length.

Abstract: 238,987. Humphreys & Glasgow, Ltd., and Glasgow, A. G. June 18, 1924. Grates; ash-pans.-A rotary grate or fuel support for water-gas producers is mounted on rollers i, j about a central blast-supply and gaswithdrawal pipe k, and comprises an eccentric cylinder with a conical top g; a scraper n is secured to the pipe k to remove ash which passes through the air spaces. The cylinder is carried by a water trough or ash-pan h<1> into which an apron l depends from the boiler; a second apron m of greater depth depends from the pipe k and the two seals so formed are connected by a passage o. The cylinder has a lining g<2> such that its inner surface is concentric with the inner wall h<x> of the trough, so that the space between the inner wall and the apron m is equal to the space between the apron and the lining. The effective depth of the seals may be indicated by air-pressure gauges q, r. The speed of rotation of the grate may be regulated automatically, for example during the down-run, by a pyrometer x or a thermo-couple in the pipe k working in conjunction with a variable speed motor. For this purpose, the needle 22, Fig. 4, of a. galvanometer 23 in circuit with the pyrometer is normally held in contact with a variable resistance 20, and a conducting bridge 21, by a bar 24 carried by a lever 25 which is periodically rocked to release the needle and allow it to take up a position corresponding with the pyrometer temperature. The needle may complete the circuit of a magnetic switch for the purpose of stopping the grate when the temperature becomes excessive. The trough is provided with shallow ribs h<2> which propel ash and clinker up a fixed incline t to the place of discharge. In a modification, the grate is enclosed in a gas-tight casing, and the clinker is directed into pockets which are emptied from time to time.

One end 12b of this spring engages the catch 6 and urges it towards the lock opening position, the other end 12a engages the support 3 in slit 13 and is bent back to engage the catch 6 and thus prevent its rotation. End 12a may move relative to the pivot axis in slot 14 and, when nearest the axis, engages stop 21 on the catch and so keeps the catch in the closed position in which the beak 8 is hooked under the keeper 9. Moving the end 12a manually away from the axis such as by turning shaft 16 and cam 15, will permit the catch to rotate until the end 12a engages the stop 19 and so holds the catch in the open position. Nose 11 on the hook 6 assists the opening by pressing down on keeper 9 and so lifting the catch and attached parts slightly away from the keeper. During closing nose 11 engages the keeper and causes the catch 6 to rotate so that end 12a of the spring slides over surface 20 and drops, under its own resilience, into the closing position against stop 21.

Title: Improvements in or relating to alternating current power switches
IPC: H01H3/26
Filed: 1942-10-27
Abstract: 566,192. Snap-action switches; induction relays. LANDIS & GYR SOC. ANON. Oct. 27, 1942, No. 15054. Convention date, Nov. 13, 1941. [Class 38 (v)] An A.C. power switch suitable for remote, manual or automatic control, is adapted to be closed rapidly by spring energy released by a motor, automatic resetting of the snap-mechanism occurring during opening of the switch at a slower rate than the closing thereof. When the induction relay 1 is energized, disc 1a is rotated in the direction P and through a disc 9 and friction clutch 9a fast on shaft 14, rotates the latter through nearly a complete turn until an arm 17 thereon is arrested by a pin 19. During this rotation, a spring 10 is tensioned and a pin 5a on an eccentric 5 is rotated to operate a spring latch 8 and free a lever 4, 4a, whereby a contact 3 on a blade spring 6 rapidly engages a fixed contact 7. When relay 1 is de-energized, or if its voltage fails, spring 10 drives the shaft 14 reyersely and, by means of the eccentric 5 and a roller 4b, raises lever 4, 4a to impart a slow break to contact 3, which is relatched open by latch 8. The inertia of the parts assists the slow movement and shocks are absorbed in the friction coupling 9, 9a. In Fig. 2, movement of control switch 20 to position a makes, over contacts 25, 24a, the circuit of relay 1 which, at the end of the switching operation, is de-energized by cam 24 changing contact 24a over to contact 26. Each switching operation is produced by a half-turn of shaft 14 in the same direction, and a two-lobed cam 11 fast on shaft 14 ensures return or completion of each movement. The driven wheel 13a is free on the shaft and drives it by means of the pins 22, 23, and the control member 5 has two rollers 5a, 5b, the former serving to hold the contact 3 open. To close, switch 20 is moved to position b to energize relay .1 over contacts 24a, 26, the roller 5a releasing lever 4, 4a to give the quick make. By fixing disc 13a to the shaft or screwing pins 22, 23 together, gearing 13 may be made to serve as a brake to provide uniform movement of shaft 14. Alternatively, Fig. 3 (not shown), a further disc fixed to shaft 14 may drive one of the shafts of gearing 13 through further gearing including a ratchet-and-pawl device to make the gearing serve as a brake ; one of the rollers of member 5 is in this case dispensed with. The contacts may be of silver and a flat movable contact may co-operate with a convex fixed contact. Each contact-pair of a multi-pole switch may have a spark chamber.
