Title: Current Limiting Circuit Breakers
Inventor: BIANCHI ACHILLE
IPC: H01H71/04
Filed: 1968-01-30
Abstract: 1,193,222. Automatic circuit-breakers; partly electromagnetic switches. S.A.C.E. S.p.A. COSTRUZIONI ELETTROMECCANICHE. 30 Jan., 1968 [20 Jan., 1967; 29 Nov., 1967], No. 4614/68. Heading H1N. A moulded case circuit-breaker whose contacts are separated upon heavy short-circuit currents by electrodynamic repulsion is provided with an over-centre operating mechanism for quick closure of the contacts only during the latter part of a closing movement. Movable contact 34 includes a main contact part 36 and an arcing contact part 38 co-operating with main and arcing contact parts 28, 30, of the stationary contact 27, the contact parts being of silver-tungsten. Contact 34 is carried by an arm 46 pivoted at 48, and a compression spring 52, Fig. 2 (not shown), acts on a pivot 56 on arm 46 to provide opening bias, the operating mechanism including a compression spring 72 providing the over-centre actuation of the contacts. Thermal and electromagnetic tripping are provided on moderate or severe overload by a bimetal 108, with adjustable structure 108b, and a pivoted armature 112a, respectively releasing latch parts 100, 104, such that parts 88-90-92-94-96-98, acting as a unit, swing latch part 100 clockwise and allow latch 82 to release latched member 80, Figs. 2, 3 (not shown), and thus allow a link 58 and the movable contact 34 to swing upward under the bias of contact-pressure spring 126 and spring 52. Manual resetting of latched member 80 is by clockwise rotation of a triangular member 66 which drives a shaft 70 against member 80. On short circuit, electrodynamic forces break main contact parts 28, 36, but spring 126 maintains arcing contact parts 30, 38, closed until the forces overcome the restraining effect of spring 88 on latch 82, when latched member 80 is released and contact arm 46 is driven upwardly. An anti-rebound latch 128, Fig. 2 (not shown), is provided to prevent arm 46 from rebounding downward by a temporary latching of the arm. The breaker is single pole or with linked multiple poles. In an alternative embodiment, Figs. 5, 7, electrodynamic forces rotate a contact-carrying arm 222 clockwise, overcoming the bias of an over-centre spring 226 which then assists the opening movement up to stop 260. Thermal and electromagnetic tripping are by a bimetal 234 or armature 243 acting on a trip lever 238 and common trip bar 240 to release the operating mechanism of contact arm(s) 218 on shaft 220. When arm 222 is moved electrodynamically its extension 222a acts on a plate 250 to shift it against a biasing spring 254, thereby rotating lever 252 and via linking mechanism, Fig. 7, releasing contact arm 218. The manual operating lever 206, Fig. 4 (not shown), is moved to its " off " position for resetting of contact arm 222 and plate 250 (via extension 206a) and the mechanism (via lever part 206b).

Title: Improvements in or relating to the sizing, dressing or rendering fast to shifting of textile threads and fabrics
IPC: D06M15/17
Filed: 1936-02-15
Abstract: Textile materials are sized or rendered fast to shifting by treatment with resin alcohols on derivatives such as esters or ethers thereof. Derivatives specified are the glycol or glycerine ethers, butyl ether, and lauric acid ester.  The sizes may be applied as solutions, for example in organic solvents such as trichlorethylene, or as emulsions, if desired in admixture with such materials as starch paste, glue solution, or tragacanth, if required together with fatty or waxy products.  The emulsions may be made using emulsifying agents such as soaps, synthetic soap substitutes, capillary active preparations, sulphonates of resin and fatty products, fatty acid condensation products, or substituted naphthalene sulphonic acids. By partial conversion of the resin alcohols into water-soluble compounds such as sulphonates, products are obtained which are emulsifiable without further addition.ALSO:Emulsions of resin alcohols or derivatives such as esters or ethers thereof may be made using emulsifying agents such as soaps, synthetic soap substitutes, capillary active preparations, fatty acid condensation products, or substituted naphthalene sulphonic acids.  Other materials such as starch paste, glue solution, tragacanth, and fatty or waxy substances may be added.  By partial conversion of the resin alcohols into soluble compounds such as sulphonates, products are obtained which are emulsifiable without further addition.

Title: Improvements in apparatus for delivering articles in succession
Inventor: CULPAN ALAN
IPC: B65G47/29
Filed: 1960-02-10
Abstract: 898,382. Conveyers. FORGROVE MACHINERY CO. Ltd. Feb. 3, 1961 [Feb. 10, 1960], No. 4706/60. Class 78 (1). Articles 15, e.g. loaves, are conveyed in succession by an intermittently operating conveyer 16 to a delivery station from where they are transferred to a wrapping mechanism by grippers (not shown). A control lever 2 which controls the opening and closing of the grippers coacts with a cam 13 on a shaft 1 driven in synchronism with the wrapping mechanism, the lever 2 normally being prevented from falling from the position shown in Fig. 1 to that in Fig. 3 by a trip member 3. A trip plate 5 controls the member 3 which normally rests on a stop 6 as shown in Fig. 1. When in the Fig. 3 position, the lever 2 allows the grippers to close on the article as described in Specification 542,234. The trip plate is pivoted at 7 to a carrier 4 with movement limited by stop pins 8, 9 and is normally held against the pin 8 by a spring 10. The carrier 4 is fixed to a shaft 20 to which is also fixed a cam lever 21 coacting with a further cam 11 on the shaft 1. The carrier is connected to the trip member 3 by a link 12, a bell-crank 18 and a rod 19. Whenever an article fails to arrive at the delivery station at the proper time, the trip plate 5 is arrested by the stop 6 in the Fig. 1 position and the release mechanism, constituted by the carrier 4, the link 12, the bell-crank 18, the rod 19 and the trip member 3, is unable to move under the control of the cam 11. If, however, an article arrives at the delivery station at any time during the forward movement of the intermittent conveyer it displaces the plate 5 clear of the stop 6 and the article is retained by the plate 5 until the movement of the conveyer has been completed. The carrier 4 and link 12 of the release mechanism are now free to follow, under the action of a spring 22, a downward movement determined by the cam 11 and in due course reach the position shown in Fig. 3. During this movement the control lever 2 is freed by the trip member 3 and moves downward as determined by the cam 13. The grippers are thus allowed to grip the article and transfer it to the wrapping mechanism. Continued movement of the cams, restores the parts to the position shown in Fig. 1.

Title: Improvements in Hydraulic Elevators.
Inventor: MASSEY GEORGE
IPC: B66B9/04
Filed: 1916-04-03
Abstract: 100,308. Massey, G. April 16, 1975, [Convention date]. Electrically-actuated valves.-Relates to the control by electrical means of the main hydraulic valve of a hydraulically-operated lift. The valve P, Fig. 4, is operated by the lever 0 attached to the toothed rack 0', Figs. 3 and 4. The motor N, provided with a magnetic brake N<2>, operates the worm N<3> and consequently the worm-wheel H. The worm wheel is mounted on the boss of one member I of an electromagnetic clutch, the other member I' being attached to the shaft E. The toothed wheel G is mounted on the shaft E, and operates the rack O<1>. When the starting- switch is operated, the motor N turns and the coils M are energized, thus pulling the armature I' into engagement with the member I. The wheel G and rack 0' are thus operated, and the valve P is opened. At the same time, the weight R is wound up on the pulley F until the pin F<2> strikes one of the switches Q, Q', according to the direction in which the lift is moving. These switches are arranged between the main switch and the motor N, so that, when the switch is operated, the brake N<2> is actuated and stops the motor N. The lift continues to move until it reaches the desired level, when the current is cut off, the clutch I is de-energized, and the weight R falls, thus bringing the valve into the closed position. In a modification, the worm gear N<3>, H is replaced by a chain and sprocket-wheel. When low-pressure water is being used, the valve is made larger and the toothed wheel G gears directly with a rack mounted on the valve stem.

A gas-cooled reactor having a concrete pressure vessel 1 has a plurality of cavities in the vessel wall each receiving a heat exchanger in which secondary water coolant is generated into superheated steam. The heat exchanger may be inserted into and withdrawn from its cavity as a unit from outside the pressure vessel. As shown in Fig. 1 the cavities 1a are horizontal and sixteen of them are equispaced around the pressure vessel circumference. The hot gas from the reactor core is conducted by a duct 3a to a cylindrical baffle 3 enclosing a superheater coil 2. On reaching a plug 7 removably closing the end of the cavity the gas flow changes direction in the evaporator portion and passes to economizer coils 6 whence it returns to the core. The secondary coolant enters the heat exchanger through a pipe 8 and leaves through a pipe 9. In another embodiment, Fig. 2, the cavities 1b are vertical and each heat exchanger includes a casing 13, the hot gas entering the casing through a tube 16, flowing downwards over the various sections of the heat exchanger under the influence of a centrifugal blower B and then returning upwards through an annular space 14 to an annular space 19 surrounding the tube 16. Access to the cavities 1b is obtained by removal of lids 10. Various tube arrangements for the heat exchanger sections are described with reference to Figs. 3-9 (not shown).

Title: Improvements in servo brake mechanism for motor vehicles
IPC: B60T13/24
Filed: 1935-02-18
Abstract: 450,697. Fluid - pressure brakes. JOHNSON, M. E., 134, Ealing Road, Wembley, Middlesex. Feb. 18, 1935, Nos. 5213 and 31545. [Class 103 (i)] In a control valve for servo-brake mechanism comprising an annular space around a reduced portion between a pair of pistons providing communication between the atmosphere port and the servomotor port, a shoulder or taper is provided connecting one piston to the reduced portion whereby the passage through the annular space is gradually restricted and finally shut off as the valve moves to open the port connected to the power source. In Fig. 2, the servomotor port h<1> is normally connected to the atmosphere port i<1> through the annular space c<4> between the two pistons c<5>, c<6> sliding in the casing c<1>. When the valve is moved to apply the brake, a shoulder x of slightly less diameter than the pistons enters the passage c<4> to provide a restricted passage for the inlet of air through the port i<1> as the port g<1> leading to a source of suction begins to be uncovered. With continued movement of the valve the port i<1> is closed by the piston c<5> and the port g<1> is further opened. The intermediate position of the valve in which a restricted entry of air is permitted when the suction port is partly open permits effective graduation of application and release of the braking pressure. The valve may be used in the arrangement shown in Fig. 1, for a vehicle in which the casing c<1> is connected to the pedal a by a member d to which also is attached one end of the bellows e, the other end of which is connected to a lever f, pivoted at f<1>. Lever f is connected also by rod b<1> to the valve c and to the brakes. Depression of the pedal operates the valve to apply the brakes by the bellows and may also apply the brakes mechanically by engagement of a stop v, Fig. 2, on the valve with the casing c<1>. In Fig. 7, the two pistons c', c<8> are connected by a tapered part r and the piston c' has a conical part q which normally closes the suction port g<1>. As shown, the valve is operated by hydraulic pressure acting on a piston k through pipe l against the action of a spring j. When the valve is moved the port g<1> is connected to the servomotor port h<1> and the passage to the atmosphere port i is gradually restricted by the part r and finally closed by the entry of the piston c<7> into the right hand part of the casing. Fig. 6 shows a system in which the valve c<1> shown in Fig. 7, operated by hydraulic pressure produced by a master cylinder n controls servomotors e which apply brake shoes by wedges p, the shoes being applied also by hydraulic cylinders o. The servomotors may however operate separate brake shoes or brakes upon other wheels for example on a trailer vehicle. The valves shown in Figs. 2 and 7 may be modified for operation, by hydraulic pressure and by pullrods respectively. The servomotors may be operated by fluid under pressure instead of suction.

Filed: 1932-02-22
Abstract: 397,477. Electromedical apparatus. HENRY, C. B., 62, Harley Street, London. Feb. 22, 1932, No. 5246. [Class 81 (ii).] An electrode for diathermy treatment comprises a tray, support, or receptacle containing or covered with electricallyconducting plastic or thermoplastic material and means for connecting the material to a source of electricity. The tray may be of conducting material with or without an insulating covering, or of non-conducting material lined with conducting material such as metal foil which does not extend to the edges of the tray. When required to treat only a portion of the area covered by the tray-an impression is first taken with non-conducting plastic material which after hardening is removed at those parts to the treated and replaced by conducting material, a second impression being then taken. Alternatively the conducting lining where used is applied where required in strips which are connected to a common or to separate electrodes. As applied to the mouth a vulcanite or like tray 1, similar to a dental impression tray, having a lining 3 of metal foil applied to leave an unlined margin 4, has a hollow insulating stem 2 through which passes a conductor 6 connected to a terminal 5 and to a metal plate 7 contacting with the lining 3. The invention is also applicable to the treatment of the vagina, rectum, nose, ear, or external parts of the body.
