Title: Improvements relating to high speed circuit breaker reclosing mechanisms
IPC: H01H75/04
Filed: 1940-07-18
Abstract: 542,585. Automatic circuit breakers; actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. July 18, 1940, No. 11849. Convention date, July 18, 1939. Addition to 526,422. [Class 38 (v)] A tripped circuit-breaker is automatically reclosed by energy stored in a spring 33, which energy is automatically released by ard during, the opening movement of the operating-rod 1 so that re-closure is effected before the opening movement is completed, the rod 1 being latched closed at L2 independently of a trippable thrust transmitting linkage T. The closing linkage comprises a releasable arm 30 on which bears a roller 12 on a floating lever 6 having a pivot 7 normally held by a toggle 23, 24 releasable by a detent 25 and coil 52, and a pivot 9 whereby it is connected by link 10 to a pivoted lever 43 which has a part 44 in the path of movement of a roller 1<SP>1</SP> on the rod 1. Arm 30 is normally retained by latches L3, L4, the former being trippable by coil 46 and the latter having an extension 47 which is deflected by roller 1<SP>1</SP> when the rod rises to open the contacts. The circuit of 46 includes contacts S1 which are closed by cam 36<SP>1</SP> only in the fully-charged position of the spring 33, at other times the contacts S2 being closed to maintain an alternative circuit to contacts ml which are closed by arm 30 when the spring-energy is released . When trip relay FR is energized, it closes contacts fr2 to energize the coil 46 and free latch L3, and closes contacts fr1 to energize, over closed contacts a, the coil 40 which releases armature 39 and allows it to rotate about its pivot 38 and impinge on latch L2 to rotate it about pivot 38 and free rod 1. In rising, the latter operates latch L4, so allowing the spring 33 at once to expand and reclose the breaker, at the same time energizing at m1 the motor M which rotates cam. 36 clockwise. The roller 35 and seat 34 drop to the low part of the cam, arm 30 falls, and latches L3, L4 again reset, the continued rotation of 36 causing the seat 34 to slide on the stem 33<SP>1</SP> on seat 32 and stress the spring 33, whereupon the motor is disconnected at contacts 52. During the reclosing movement, the lever 43 acting through spring 49, restores the armature 39 against the trip magnet. The breaker can be closed manually from the fully-open position by tripping L3 by closure of switch C, during which operation, a cam 50 on rod 1 momentarily closes a switch b which operates a relay TR, the contacts tr1 of which remain closed while a time-lag expires, and prepare a free-release circuit for coil 52, which circuit can be completed by the relay FR. Manual tripping is effected by contacts O in shunt to those fr1, ready for re-closure by C.

Title: Improvements relating to handling and treatment of loose materials
IPC: C22B3/02
Filed: 1923-05-08
Abstract: 221,249. Adam, M. A., Fieldhouse, J., and Baillie, R. May 8, 1923. Cleaning and pickling.-Loosely bundled materials such as tin scrap are enclosed in cylindrical perforated containers which are carried with a rolling motion through one or more vessels containing wheels with spokes between which the containers are carried, and a stripping treatment is applied in these or other vessels by means of a solution such as that described in Specification 154,635, [Class 41, Electrolysis], or by chlorine gas. The process may be combined with the electrolytic treatment of the tin solution by arranging a cathode under the spoked wheel, the material in the containers acting as anode. The containers a are fed to vessels e, f, g containing treating solution, water, and alkaline solution respectively, the liquor in the vessel e being circulated to and from an electrolytic apparatus. Additional vessels may be employed for de-decorating the scrap material if necessary. Alternatively a cathode z may be arranged under the spoked wheel d, Figs. 7 and 8, and its surface is swept by a rubber strip y carried by a cross piece x supported by pieces w upon the spokes of the wheel d. The deposited metal is thus swept into a cathode sump. In another modification, for the gaseous treatment, the spoked wheels are arranged in liquid seal chambers q, r, Figs. 5 and 6, which may contain carbon tetrachloride. The containers pass through a gas treatment chamber s with or without chambers v containing spoked wheels. The sealing may be effected by flap doors similar to those used in refrigerating plant, these being placed adjacent to the spoked wheels, and used instead of or in addition to a sealing liquid.

Title: Improvements in or relating to Machines for Drilling or Punching Holes for Rivets or the like.
Inventor: MCKECHNIE JAMES
IPC: B23Q35/02
Filed: 1917-09-04
Abstract: 128,968. McKechnie, Sir J., and Wallis, B. N. Sept. 4, 1917. Punching.-Means for drilling or punching accurately-pitched holes in channel or other bars, either automatically or semiautomatically, are described with reference to drilling. A machine for drilling a channel bar has two opposite drill-heads which are angularly adjustable in slides C<2> vertically adjustable on brackets C<2> which again are transversely adjustable on the machine-bed. The work is fed between a driven roller b and a pressure roller c. Before introducing the work the roller c is raised by a hand lever h acting through a cam and a lever d. The work is then pushed forward against a stop i, adjustable to suit the distance of the first holes from the end of the bar. The hand lever is then actuated to lower the roller c. The feed roller is driven through a friction gear by the belt pulley b<1> which also drives through a shaft k<1> and the gear l<1>, m<1>, n<1> and a pitch plate r or an equivalent device. On this plate are adjusted dogs which, when they strike a stop v, Fig. 2, arrest the movement of the pitch plate and the feed roller. The pitch plate is driven from the gear n<1> by a sun-andplanet motion, the planets being carried by a disk to which movement in either direction can be given to vary the pitch by pins u<1> carried by the pitch plate acting on a wheel z<1> which through a reversing-gear rotates the planet disk. Each drill spindle is driven by a belt pulley i<2>, and fed to drill a hole and then withdrawn bv rack and pinion gear driven by an oscillating shaft n<2>, which receives movement from a crank disk k<2> driven by a one-revolution clutch from a belt pulley j‹. After the work has been introduced the attendant operates a lever p<4> to put in gear the one-revolution clutch so that the first holes are drilled. As the disk k<2> completes its revolution, a cam on its shaft removes the work stops and the stop from the dog on the pitch plate which then, with the feed roller, is driven by the friction gear to feed the work until the next dog on the pitch-plate abuts against the stop v which has been replaced meanwhile. Just beiore the stop comes into action, a. projection on the pitch plate actuates a lever which throws in the one-revolution clutch to drill the next set of holes.
