Patent GB-219723-A (GB)
Title: Improvements in or relating to electric circuit breakers and the like
IPC: H01H71/24
Filed: 1923-04-03
Abstract: 219,723. Reyrolle & Co., Ltd., A., Clothier, H. W., and Leeson, B. H. April 3, 1923. Automatic circuit-breakers; electromagnetic switches; sparking, preventing; cut-out arrangements. - A high-speed overload switch, or current diverter (which introduces a resistance into a circuit without actually breaking it) comprises two separate magnetic circuits, one having two air gaps and energized by a series winding and tending to move on the armature connected to the contact member in a direction to break the circuit, and the other energized by a shunt winding and tending to hold the armature in the position in which the circuit is closed. An additional winding on the shunt core may be used to enable the switch to be closed electromagnetically. In the construction shown for use in a traction system, the core A carrying the series winding D is formed with a gap in which the contacts are located and are subjected to the blow-out action of the flux therein, as described in Specification 167,846. The armature C is pivoted at C<1> and serves as a keeper for the second gap in the series core or for the shunt core B energized by the windings E, E'. It is shaped so as to bed closely upon the respective pole faces and is connected by rods H controlled by springs H<2> to the pivoted movable contact-member F. The switch is shown in the closed position in Fig. 2, the contact member F engaging the fixed contact F'. When on fault, the series current increases (usually accompanied by a drop in the shunt current) the pull of the series magnet on the armature overcomes that of the retaining shunt magnet and the pull increases as the armature moves, while, at the same time, the retaining force falls off thereby affording a high-speed action. Moreover, at the commencement of the heavy overload, the reduced flux through the armature due to the shunt winding admits, in the same direction, an increased flux from the series core and, consequently, the reactance of the series winding is increased and the rise of the overload current is retarded. A variable resistance J is provided to adjust the shunt current, and, in the form shown in Fig. 2. the switch in opening, instead of breaking the circuit, increases a resistance K in shunt with it. As used in connection with a traction system in which bus-bars L, L<1>, Fig. 3, supply overhead and track conductors N, N', ordinary circuitbreakers 0, P are employed and in the event of fault, the high-speed switch F, F<1> introduces resistance into the circuit which is broken finally by the circuit-breakers 0, P. The circuit-breaker P, in opening, completes the circuit of the auxiliary closing coil E<1> on the core 13 and the high-speed switch is automatically reclosed.

Title: Polyurethanes
Inventor: TRAPPE GORDON
IPC: C08G18/79
Filed: 1964-03-04
Abstract: Cured elastomeric polyurethanes are produced by the condensation of one or more linear hydroxyl-ended polymers of M.W. 800-5000, one or more organic diisocyanates and optionally a compound of M.W. less than 800 containing two active hydrogen atoms whereby a polyurethane containing 0.5 to 5.0% of uretdione groups is obtained and curing the polyurethane in the presence of sulphur or an organic peroxide. One of the polyurethane precursors may contain olefinic unsaturation, thereby introducing unsaturation either in the polyurethane chain or in pendant groups.  The linear hydroxyl polymer may be a polyester, polyether, polythioether or polyacetal.  The uretdione groups may be introduced by the use of a diisocyanate containing a uretdione group, e.g. a dimer of tolylene diisocyanate.  Fillers, curing accelerators, plasticizing agents, flame proofing agents and antioxidants may be added.  In the example a polyester was reacted with tolylene diisocyanate and then dimeric 2:4 tolylene diisocyanate added, the mixture heated and compounded with: carbon black, 2-mercaptobenzthiazole, 2:21-di-(benzthiazyl) disulphide, sulphur, stearic acid, ZnCl2 and heated to cure.

Title: Improvements in and relating to electric measuring instruments
IPC: G01R15/18
Filed: 1941-07-24
Abstract: 548,681. Current measurements. BRITISH THOMSON-HOUSTON CO., Ltd. July 24, 1941, No. 9395. Convention date, July 24, 1940. [Class 37] A high frequency ammeter comprises a fluxresponsive armature arranged within the magnetic field of a conductor carrying the current so as to vibrate at a rate proportional to the flux. As shown in Fig. 1 a load 10, which may be a radio transmitter, is supplied with high frequency current from a source 13 through a concentric cable comprising a conductor 11 and a tube 12. Through a longitudinal slit 14 in the tubular conductor 12 is suspended a small armature 15 formed by a single turn closed copper coil. This is fixed to a stem 16 passing through the slit 14 and carrying a small mirror 17. The moving system is suspended by a quartz fibre 18 supported from a standard 19. The mirror 17 and its suspension may be enclosed in a glass tube 22. Light from a source 23 is reflected from the vibratory mirror 17 through a slit in a shutter 24 on to a photo cell 25 connected to an amplifier 26. In the output circuit of this is an electromagnet 27 which has an armature secured to a recording stylus arm 28 marking on a chart 30 which is driven at uniform speed by a clock 34. The distance between consecutive markings gives the time between successive passages of the light ray past the shutter 24, from which the current may be calculated. The current distribution curve along the line may be determined by moving the coil 15 along the line through the slit 14 and measuring the current at different points. In a modification, Fig. 3, concentric conductors 41, 42 are short-circuited by an integral end wall section 43. The armature 15 is pivoted in a framework 44 secured to the outer conductor 42. The ammeter is connected at any point in the high frequency line 11, 12. A variable condenser 45 may be connected in series with the ammeter and adjusted until the ammeter circuit is tuned to resonance. Small holes 46 are drilled in the outer conductor 42 in line with the armature so that a light beam 47 is interrupted when the armature swings through a neutral position, the interruptions being recorded by means of a photo-cell 25. Fig. 4 shows the ammeter arranged for calibrating another high-frequency ammeter 49, which may be of the thermo-couple type. The terminal 50 on the centre conductor 11 is connected to the centre terminal 51 of the ammeter 49 and the outer conductor 12 is connected to points 52, 53 which form the other terminal of the ammeter 49. Connected in the incoming inner lead 11a is a variable condenser 45 adjusted by turning an insulating cap 54 which closes the end of the tubular conductor 12 and has a hub through which the incoming lead 11a is threaded. Instead of the armature 15 being a copper ring it may be a ring or bar of magnetic material, or a metal disc.

Title: Improvements in and relating to adjustable struts for air-craft
IPC: F16B7/12
Filed: 1936-03-30
Abstract: 458,005. Aircraft alighting - gear. ELEKTRONMETALL GES., 26, Pragstrasse, Bad Cannstatt, Stuttgart, Germany. March 30, 1936, Nos. 9451 and 9452. Convention dates, March 28, 1935 and March 27, 1936. [Class 4] [See also Group XXX] In a strut of variable length for the undercarriages of aircraft comprising a piston moved in a cylinder under the influence of a pressure medium and having balls for effecting the locking of the strut in different positions, the balls lie in recesses in such a manner that in the locking positions tensile and compressive forces are taken up and transmitted in both directions. The main piston 2 is formed with recesses in which are located balls 8, 9 which in the retracted and extended positions of the strut are engaged with recesses in the main cylinder 1 by sleeves formed on looking pistons 4, 5. To extend the strut pressure built up by fluid admitted through a pipe 12, moves the piston 4 against its spring 6 and then operates on the piston 2 which together with the rod 3 is moved downwardly. Towards the end of the extension stroke the balls 9 engage the tapered end of the sleeve of the piston 5 which is pressed downwardly against a spring 7 until the balls engage in the recess 14 when the sleeve moves upwardly under the action of the spring 7. The strut is contracted in a similar manner by fluid admitted through the pipe 13. In an alternative arrangement, Fig. 3 (not shown), operating cables are attached to levers connected to the upper and lower locking pistons so that the unlocking operation may in each case be effected independently of the application of fluid pressure. In a further modification, Fig. 4 (not shown), the unlocking piston is connected to a lever operated by a piston moving in a cylinder fed from an auxiliary source of pressure.

Abstract: 564,299. Teaching drawing. LAMBERGER, B. June 21, 1943, No. 9984. [Class 11] In an appliance for teaching drawing, means by which a copy or model is rendered visible through a translucent drawing-surface is connected with the pencil or other drawing - instrument, so that the pencil is held out of operative position as long as the copy is visible. The pupil is thereby obliged to visualize the object whilst it is being drawn. In one form, drawing-material 2, Fig. 1, extending between rolls 3, passes over an aperture in a table 6, which may be covered by a glass plate, and the drawing-copy 4 is carried by a pivoted arm 5, which is connected by a string 10 to a pencil 7. The pencil is thus held away from the drawing-surface as long as the copy is in view, and is lowered when the copy is removed. In a modification, the copy is carried by a slide 25, Fig. 3, and is interrupted by parallel white strips. Above the slide is a celluloid plate 19 having alternate clear and white strips, on which the drawing is made. A pencil or fountain pen 11 slidable in a tube 12 is connected to the slide 25 by a wire 15 passing through a tube 16. As long as the picture strips or the copy are visible through the clear spaces of the plate 19, the pencil is retained within the tube 12 and cannot be used. When the pencil is projected by means of a stud 13, the slide 25 is moved so that the copy is hidden by the white strips of the plate 19. The copy may be projected on to the drawing-surface by an optical projection device controlled by the movement of the pencil.
