Abstract: 1,104,481. Closing sausages. UNITED GAS INDUSTRIES Ltd. 22 June, 1965 [23 June, 1964], No. 25816/64. Heading A2B. [Also in Divisions B3, B6 and B8] Casings for sausage meat or other food products are clipped at their ends with metal strip or wire, when filled, the clips being applied simultaneously by means of a pair of clipping devices (one shown in Fig. 3) of which one is adjustable relative to the other. A coil of metal strip contained in a receptacle (12), Fig. 2 (not shown), is fed forwards through a slidable mechanism (15) having a pivoted feed pawl and passes under a retaining pawl 16, Fig. 3, to a position where one of a pair of vertically moving elements 21 cuts off the end section of the strip against the edge of a block 26. The elements 21 continue rising thereby causing the two ends of the clip blank so formed to be bent upwards, the centre part of the blank being held down by metal members 27 which overlap its side edges. When portions 30 of the elements 21 engage the lower face of a block 22 in which the die members operate, a central die 10 continues to rise against the action of springs 33 and force the partially formed clip upwards past the members 27. This action causes the edges of the base of the now U-shaped clip to be bent down against the members 27. Each clip engages the respective end of a casing placed in a slot 19 formed in housing plates (17, 18), Fig. 4 (not shown), and is closed as it enters a slot in a die 20 moved into position by manual or power means. While the clips are being applied, the casing is gripped by a pair of jaws (38, 39), Fig. 1 (not shown), each of which is situated outwards of its respective clip mechanism. A control device, operated by press button valves, may actuate pneumatic cylinders moving the machine parts. The members 27 may be replaced by spring-loaded elements having faces which co-operate with lateral studs on the die 10.

Title: Apparatus for producing patterned deep pile knitted fabric
IPC: D04B9/14
Filed: 1971-04-19
Abstract: 1350966 Knitting machines; high pile fabrics BUNKER-RAMO CORP 19 April 1971 [20 Aug 1970] 26032/71 Headings D1C and D1K A rotary cylinder circular knitting machine for knitting pile fabrics comprises feeding means 14a, 14b which deliver pile fibres from separate supplies to spaced zones from which they are picked up by needles 6 selected by patterning means which also control the fibre feeding means according to the number of needles which are going to take fibres from a particular zone. At four stations selected needles 6 are moved upwardly in sequence to receive pile fibres, which are orientated by air jets, from a carding and feeding unit 8 and a body yarn 10. Each unit 8 includes the sliver feed rollers 14a, 14b controlled by clutch units 15a, 15b and feeding slivers e.g. of different colours. Needles 6 have intermediate jacks 32 and pattern jacks 34 with frangible butts. Selectors 38 select jacks 34. Paths 44a, 44b are the paths respectively of needle butts which have and have not been selected and an immediate reselection causes selected needles and unselected needles to pass along paths 44c, 44d. Thus the needles can take two different colours at one feed. At least one of each pair of rolls 14a, 14b has a clutch system 15b, Fig. 5 the other roll being geared to the clutch driven roll or weighted against it and the rolls are independently rotatable in frame 70. Different diameter gears 76, 78 on shaft 71 mesh with gears 80, 84 respectively keyed to shaft 82 and carried on a sleeve 86 carrying electro-magnetic clutch elements 88a. Elements 88a co-operate with elements 88b carried on a sleeve 90 fixed to a continuously driven drive gear 92. Shaft 82 and sleeve 90 carry respectively the elements 94a, 94b of a second electromagnetic clutch 94. The control for the machine comprises a tape 100 advanced incrementally by a motor 108 of a transparent tape with darkened areas, a perforated tape or a magnetic tape which is read by a scanner 106. The timing of motor 108 is controlled by a clock pulse generator. Fig. 6 shows only the control system for a single fibre feed clutch and a single needle selector bank. (For Figures see next page)

Title: Improvements in or relating to hydraulic shock absorbers
IPC: B61G11/12
Filed: 1958-08-15
Abstract: 861,286. Shock absorbers; railway vehicle buffers; railway vehicle combined buffer and draw gear. ATELIERS DE CONSTRUCTION DU NORD DE LA FRANCE. Aug. 15, 1958 [June 9, 1958], No. 26302/58. Addition to 855,818. Classes 103(5) and 108(3). The hydraulic shock absorber described in the parent Specification is applied to a shock absorbing coupling device for railway stock. When a shock is exerted on a drawn head 24 it is transmitted to a plunger body 3 by means of a stem 16. The plunger begins to move into the interior of a casing 7 which bears against a stop rigidly connected to the housing 23. This movement of the plunger causes movement of a piston 2 inside the plunger body. The shock absorber consisting of the piston 2, the plunger body and a floating body 1 then functions in the manner described in the parent Patent. A volute spring 11 opposes the movement of the plunger 3. When a tractional force is exerted on the draw head 24, it is transmitted by means of the stem 16 and a draw strap 18, pinned thereto by a pin 19, to a plate 7a forming the end of a casing 7. The casing 7 telescopes over the plunger 3 which bears against a stop rigidly connected to the housing 23. This telescoping movement is again opposed by the shock absorber mechanism and the volute spring.

Electric arc welding apparatus for the manufacture of submarine telephone cable which comprises a copper strip 3 folded around an inner steel supporting member 5 by a forming mill 4, the seam in the copper strip then being welded in an argon atmosphere at 1 is provided with a device for stopping the welding operation should the ratio between the welding current and the speed of welding become such as to produce a poor weld. A tachogenerator 15 is associated with the mill 4 to measure the welding speed, the output of the tachogenerator energizing one coil 12 of a differential reed relay 8. The output of the tachogenerator is also fed to a control unit 19 which unit controls the welding power source 6 to control the magnitude of the welding current, the welding circuit including a second coil 7 on the relay 8. Under normal conditions with the ratio between the welding current and the welding speed being such as to produce satisfactory welding, the opposing energizations of the two coils 7, 12 of the relay 8 balance such that the contacts 16 thereof are open. Should the ratio alter the energizations of the two coils become unbalanced, whereupon contacts 16 close to energize relay 17, closing contacts 20 to actuate a relay 26 which disconnects motors 21, 22, 23 which drive the forming mill 4, a caterpillar 10 which draws the strip 3 and supporting member 5 through a reducing mill 9 and the take-up drum 11 respectively.

Abstract: 1365283 Steel for electromagnetic use BRITISH STEEL CORP 26 Aug 1971 [2 June 1970] Heading C7D Steel is vacuum treated to reduce its carbon content to a level below that finally required, followed by addition of carbon and silicon under vacuum to produce the desired concentrations. Preferably after the initial treatment the steel is deoxidized e.g. with aluminium, which may be added during the vacuum treatment, as may the carbon and silicon. In a preferred embodiment a melt containing 0À02% to 0À07% carbon is vacuum treated to reduce that level to below 0À025%, followed by adjustment of the composition to 2À5% to 4% silicon and 0À02% to 0À04% carbon. Initial oxygen level may be 0À04% to 0À14%, and final level below 0À006%. The silicon addition may be made before or after the carbon, or either may be added in a number of separate batches.
