Abstract: 994,648. Fish, gutting. FISDACO Ltd. May 16, 1963 [June 15, 1962], No. 23151/62. Heading A2U. In a fish gutting machine of the type comprising means for conveying the fish belly downwards over a belly-slitting knife over a device which dislodges the guts so that they hang down suspended only from the vent and throat attachment points, co-operating members, e.g. rollers, endless chains or bands, are provided which form between them a nip into which the gut moves so that it is pulled away from the fish under tension and its severing at the throat is facilitated. The gut 11 moves into the tapering entry between a pair of contra-rotating ribbed and grooved rollers 13 and is dragged down and held taut as it moves between a pair of contra-rotating disc knives 17 which sever it close to the throat of the fish. Severing at the vent 19 is similarly accomplished. The knives 17 are driven by shafts from gearing 40 driven in turn by a transmission (not shown) from the shaft of the main conveyer sprocket 4. The rollers 17 are also driven by gearing mechanism 24, 25, 30, 31, 32, 36 37 from the sprocket 4. The fish conveying, belly slitting and gut dislodging means is preferably as described in Specifications 878,957 and 880,394 and a device for separating the livers from the walls of the belly cavity as described in Specification 980,445 may precede the rollers 13.

Abstract: 461,630. Jacks. STANDARD TELEPHONES & CABLES, Ltd., GRACE, B. B., and SMITH, C. P. Aug. 19, 1935, No. 23282. [Class 40 (iv)] A contact spring assembly, e.g. for a telephone jack, has the inner springs 5, 7 of two adjacent sets 4, 5 and 6, 7 spaced by a movable member 8, a fixed member 9 of less width than 8 being also located between the springs 5, 7 which make contact therewith at different times during the operation of the spring assembly. When the plug is inserted, spring 4 moves to the right followed by 5, 7 and 6 until 7 abuts against fixed member 9 whereupon 4, 5 break contact. When the plug reaches spring 6 and moves it to the left, 7 and 5 follow until 5 abuts against 9 whereupon 6, 7 break contact. The spring 4 also controls a break-before-make set 10, 11, 12 of which 11 is stiffer than 10 and 12. When this set is operated, spacing member 13 moves to the right out of contact with 10 so that if the plug becomes worn, the set is still correctly operated. Relative movement between the contact points of all sets takes place during insertion and removal of the plug to give a selfcleaning action.

Patent GB-517984-A (GB)
Title: Improvements in and relating to gas blast electric circuit breakers
IPC: H01H33/70
Filed: 1938-08-12
Abstract: 517,984. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 12, 1938, No. 23841. Convention date, Aug. 12, 1937. [Class 38 (v)] The gas-supply chamber 16 is separated from the exhaust chamber 1 (with silencer and cooler 6) by an insulating, for example, gas - evolving, or metal chamber 2 in or into which the arc may be formed or forced. The outlet may be in the form of a Laval nozzle 18 and is wider than the inlet nozzle 17 which may also serve as a contact. Alternatively a special contact 5 for co-operating with pin-contact 4 may be provided and adapted to pass gas either continuously or only during switching. A counter-contact 7 may be located in the nozzle 18 and connected electrically to contact 5. When the contact 4 is withdrawn from contact 5 or 17, the arc sets up a high pressure in chamber 2 during the high instantaneouscurrent periods, the effect of which is to oppose the pasage of the blast from 16 into the chamber 2 at a time when the arc cannot be extinguished. At the same time the gas escapes from 2 into 1 at a high speed so that when the current is near zero of the cycle, the pressure in 2 is reduced sufficiently to enable the blast from 16 to flow and quench the arc. The arrangement thus prevents premature presure-increase in the exhaust chamber 1 at high instantaneous-current values, which pressure would act to prevent the blast proper from acting on the arc at the time when the latter can readily be quenched, namely at zero of the cycle. Modifications comprise the use of two or more outlet nozzles emanating from the same point of chamber 2, and the use of funnels or cones arranged one above the other in chamber 1, cooling air being sucked in through the annular spaces between the funnels, for example, through apertures in the wall of chamber 1, Figs. 2 - 4 (not shown).
