Title: Improvements in and relating to multi-pole electric circuit breakers
IPC: H01H71/52
Filed: 1958-06-30
Abstract: 871,931. Automatic circuit-breakers. FEDERAL PACIFIC ELECTRIC CO. June 30, 1958 [July 3, 1957 (2)], No. 20922/58. Class 38 (5). A multi-pole circuit-breaker has a currentresponsive latch and a contact arm for each pole, the arms being coupled to a common handle by toggle connections arranged so that the displacement of the toggle of one pole, when that pole is tripped on overload allows collapse of the toggles of the other poles to initiate their opening movement before the contacts of the overloaded pole separate. Each pole has a contact arm 50 pivoted on a spring 52 and carrying a bimetal latch 62 and magnet core 76, all generally similar to the unit described in Specification 778,952. The end of the latch 62 engages a bimetallic compensating member 60 on an arm 56 insulatingly pivoted at 54 on the contact arm. The handle 30a is an extension of a moulded member 30 which is coupled by a metal shaft 34 to two further moulded members 28, 32 which are journalled in the composite casing. The members 28, 30, 32 form a composite operating member which has two extensions 28a, 32a enclosing members 36 having projecting pivots 36a which engage in slots 40 in the ends of a common trip-bar 38. This bar has apertures for three wire members 42a, 42b, 42c which are pivoted at 58 to the arms 56 of each pole, and normally engage stops 38a of the bar 38. Fig. 2 shows one pole in the open position with the pivot 36a at the top of the slot 40 owing to a spring-biased plunger 78 on the bar 38 engaging the member 30. During movement to the closed position, Fig. 1, the toggle formed by the members 36, 38 passes over-centre and the knee pivot 36a passes to the lower end of the slot 40. When the latch 62 disengages the member 60 the spring 52, which is stressed in the closed position, causes the arm 56 to move about the contacts to the Fig. 3 position before the spring 72 opens the contacts. This movement causes anticlockwise rotation of the bar 38 and collapse of the retaining toggles of the other two poles and all their contacts open substantially simultaneously even if the handle 30a is held in the " on " position. The handle is automatically restored to the "off" position to reset the toggles but it may be held in an intermediate position by friction so as to require hand resetting. The apertures in the bar 38 for the ends of the members 42a, 42b, 42c are formed by aligned ends of openings moulded in opposite faces of the bar (Figs. 9 to 12, not shown). Specifications 737,604 and 739,620 also are referred to.

The space between the member 6 and the envelope may be filled with glass fibres or these may be attached to the inside of the envelope wall. In other arrangements the envelope has a thickened wall portion acting as a lens to magnify the flicker effect, metallic particles may be embedded in the envelope wall or the wall may have regions of different colours. Two Ne tubes may be provided within a single outer envelope (Fig. 9, not shown).

Abstract: 884,243. Inflatable life-jackets. GOODRICH CO., B. F. June 15, 1960, No. 21039/60. Class 77. An inflatable life-jacket comprises superimposed sheets of fluid-impervious flexible material permanently joined to each other at their peripheral margins to provide a number of superimposed independently inflatable chambers with each chamber continuous throughout all the inflatable portions of the garment, which portions comprise a head rest portion, a torso portion at the front of the garment and a collar portion which extends about a neck opening in the garment. The life-jacket comprises a collar portion 21, Fig. 1, having an integral head rest 22 and an integral torso portion 23, all of which are inflatable to maintain the wearer upon his back with the head forwardly and upwardly inclined and the integral collar, head rest and torso portions are formed of three superimposed individual inflatable chambers 33-36, Fig. 6, formed of plies 25-28 which are superimposed, sealed together at their peripheries and reinforced with crotch tapes 29-31.

The torso portion of the garment is of elongated form and divided into lobes 43, 44 which are detachably joined by a slide fastener 45, and a non-inflatable back pack 24 underlies the head rest, to the lower wall of which it is attached to provide a flexible-walled receptacle for articles. The pack has its upper and side walls closable by slide fasteners 60, 61 and its lower end is securable around the waist by a strap 62 engaging buckles on straps 78, 79 on the torso portion, and the lobe 44 has an attaching strap 46 which passes around the waist to engage a buckle 48 on the strap 47. Each chamber 33-36 is separately inflatable, the outer or front chamber 35 being orally inflated through a valved tube 58 and the other chambers by carbon dioxide from cartridges in containers (not shown) which are punctured by means 53 and pull-cords 57, one on each lobe. In a modification, Figs. 12 to 15 (not shown), the torso portion comprises inseparable lobes, the back flap is not hollow nor adapted to receive articles and the attachment means on each of the lobes comprises a strap and buckle arrangement for attachment to the wearer.

Abstract: 863,152. Spring assemblies. PULLMAN (PATENT) PRODUCTS Ltd. June 25 1957 [July 6, 1956], No. 21070/56. Class 52(4). [Also in Group XXII] Relates to a method and machine for assembling upholstery springs in which successive rows of coil springs are connected together by tie-wires having preformed laterally extending hooks and are then drawn to the rear of the machine to enable the operation to be repeated. According to the invention the tie wires are clinched to the coil springs while the coils are drawn to the rear of the machine. As shown in Fig. 1 and 3 the clinching jaws 6, 8 are mounted on an actuating bar 1 moving in a support 2 fixed to a cover plate 4. The movable jaw 6 is fixed on a driver 9 sliding on the bar 1 and having a diagonal slot 15 embracing a pin 14 fixed to a toothed wheel 13 engaging a rack 12 on the underside of the cover 4. A spring locating means comprising side arms 17 pivoted about a pin 21 sliding in a slot 18 is pivoted to a spring positioning device 23. Loading hooks 60 for fresh springs are slidably pivoted to the arms 17 and are linked with the arms to the actuating bar 1 so that the process of coupling springs together by setting the outermost convolutions of adjacent springs at an angle to each other as described in the Specification 769,295 may be carried out by tilting the arms 17 and the positioning device 23. In a second embodiment (Fig. 6) the driver 9 for the movable clinching jaw is connected to the actuating bar 1 by a duplicated toggle linkage 41, 45, the pivot of each linkage carrying a roller 43 travelling completely round the cammed surface of a member 49 pivoted to the cover plate of the machine. In the position shown in Fig. 6 the clinching operation is taking place. Specification 515,821 is also referred to.

Examples I, II, III, IX and XI describe production of the polymers always using dispersion technique, examples II and III using acrylonitrile and ethyl acrylate as the second ingredient and the remainder using methyl acrylate. Dodecyl mercaptan is included in the reaction mixture of example II and in this example the reaction product is precipitated with aluminium ammonium sulphate solution and washed with water and methanol to give a white resinous copolymer which is soluble in acetone, methyl ethyl ketone and dioxane.  In the other examples the emulsion resulting from polymerization is applied to photographic films without separation and purification of the copolymer.
