Abstract: 1,214,725. Walking beam conveyers for furnaces. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 Aug., 1969 [14 Aug., 1968], No. 38918/68. Heading F4B. [Also in Division B8] In a continuous metal heating furnace of the walking beam type, billets 1 are moved faster through a soaking zone 5 than through a preheating zone 3 by walking beam systems 29 and 9, transfer of the heating billet 1B from system 9 to system 29 being from a datum line or stop 35 formed by the ends of fixed beams 31 in system 29. System 9 comprises fixed beams 11 and. movable beams 13 supported by rollers 15 on bell cranks 17 actuatedby hydraulic motor 21 and system 29 comprises the fixed beams 31 and movable beams 33 supported by rollers 37 on bell cranks 39 actuated by hydraulic motor 43. An hydraulic motor 25 provides the horizontal movement of both sets of movable beams 13 and 33. From the position shown in Fig. 2, beams 13 and 33 are lowered, fully reversed.so that beams 33 are below the billet 1B in the datum position, raised and then advanced by a distance 27. During the last movement billet 1A strikes the ends 35 of fixed beams 31 occupying the datum position. Beams 13 are then lowered to deposit their billets on. beams 11, whereupon beams 13 and 33 are moved together to complete the distance 49, beams 33 then, being lowered to deposit billets on fixed beams 31. These billets will.thus have been moved further than those in the preheating zone 3. The stop arrangementmay be formed by one or more abutments either fixed to or movably associated with the stationary beams 11 and the movable beams may be operated independently and alternately. The system may be applied to a production line in which articles are required to arrive singly at selected stations and in spaced relationship. The two walking beam systems may also be disposed at the same level.

Title: Process for avoiding fraying of cut fabrics and products obtained by this process
IPC: D06H1/02
Filed: 1962-10-16
Abstract: The tendency of bands of fabric intended to be transversally cut from segments, to fray is reduced by impregnating them in at least one transverse strip forming the cutting zone with a composition containg a solvent, e.g. acetone in the case of cellulose acetate fabrics, which unites the fibres with one another by dissolving followed by evaporation.  The process is applicable to the printing of labels on fabrics, the fabrics being printed in the cutting zone with an ink containing a solvent for the fibres.  The marking of the cutting zone by printing may be effected with the ink used for the printing of the actual label. The cutting zone may be in the form of two narrow printed strips separated by a narrow unprinted space.  Alternatively the cutting zone may be marked by using a colourless composition containing a solvent for the fibres, a colourless impression being obtained in the form of a modification of the superficial appearance of the fabric.

Abstract: 871,765. Self-sustaining gear. WRIGHT, B. M. Feb. 22, 1960 [Dec. 11, 1958], No. 39982/58. Class 78 (5). A pulley 1 is mounted on a base-plate 2 which carries a pawl 3 of wood or plastics, spring or gravity urged into engagement with the pulley rim. As applied to the tightening of a halyard by a succession of pulls, the rope is held with the minimum of effort between pulls due to the locking of the pulley 1 by the pawl 3, and the friction of the rope 4 on the pulley rim. The pawl may have a tail (not shown) by means of which it may be disengaged when under load.

Abstract: 1,062,695. Self-processing cameras. INTERNATIONAL POLAROID CORPORATION. March 26, 1964 [March 29, 1963], No. 40031/66. Divided out of 1, 062, 692. Addition to 1, 00, 569. Heading G2A. In the self-processing camera of Specification 1, 062, 692 in order to confine the spreading of the processing liquid between the sheets as they are pressed together for the image transfer process, a device is provided for pressing together the edges of the sheets, so that the liquid does not escape. The central element of this device is a block 100 of a plastics material, which is slidably mounted between guide plates 98 riveted at (99) Fig. 4 (not shown) to the plate member 64. A bar 122, also of a plastics material, has two arms 130 and a crossbar 132. It is attached to a part 112 of block 100 by a shaft 140, and centred thereon by springs 144. The fit of shaft 140 is loose enough to permit a certain amount of play as regards both rotational movement and linear movement in various directions. The ends of bar 122 are so shaped and tapered as to guide the film assembly correctly and reduce friction. A spring element 134 is attached to the rear surface of bar 122 by means of a hole 138 which engages a pin 136. The ends 134b of element 134 are bent twice at right angles round the ends 134a of bar 122, so that they come in front of the bar. Bearing surfaces 134c of spring element 134 are in contact with bearing surfaces 124 of bar 122, and it is these contacting surfaces which keep the margins of the film sheets firmly pressed together as they pass, so preventing any escape of processing liquid. The loose-fitting construction of the various parts of the margincompressing device allows a moderate deviation from the normal in pulling the film sheets out of the camera Fig. 11 (not shown) without impairing the image quality.

Abstract: 1,162,226. Making caps; metal strip feeds. L'ALUMINIUM FRANCAIS. 19 Sept., 1966 [22 Sept., 1965], No. 41768/66. Headings B3A, B3Q and B3W. An apparatus for making caps comprises a metal strip feed unit 1 with a pair of opposed feed rolls 11, 12, a pair of switches 15, 16 which are activated by the loop of strip material 91 to control the operation of the motor 14 for the rolls 11, 12, a fixed gripper 21, 22 which cooperates with a reciprocable gripper 23, 24 to feed the strip intermittently to a cutting and stamping punch 3 after which the blanks are fed to a final shaping die 5. The strip 90 is fed past a lubricator 10 by the feed rolls 11, 12, at least one of which is driven from the motor 14. Since the strip is moved by the grippers 21-24 intermittently a loop 91 is formed in the strip after the feed rolls. The upper switch 15 is closed when the strip touches a sensing member 151 and energizes a coil 174 to start the motor 14. When excess of strip is in the loop the strip touches a sensing member 161 resulting in the motor 14 being switched off. The strip is fed from the loop to the stamping unit 3 by the grippers 21-24. The gripper 21, 22 comprises a fixed electromagnet 21 and a magnetic mass 22 whereas the gripper 23, 24 comprises a movable electromagnet 23 and a magnetic mass 24. The grippers 21-24 co-operate to feed the strip, the movable gripper 23, 24 being activated by a solenoid 26 which is energized by a switch 33 on the stamping unit. The stamping unit preferably comprises a punch 31 and a die 32 with an annular cutter 311 and an annular recess 321 respectively to cut out and shape the blank. The blanks are fed to a storage hopper 42 which has a vibrating plate 421 and a discharge tube 423. The tube 423 has one or more cones 422 which allow the caps which are correctly aligned, i.e. rim uppermost, to pass by to the finishing punch 5. Any caps which pass by the cones and are misaligned are ejected through an aperture 431. The punching unit 5 is preferably of the type described in Specification 1,122,197 and comprises two punches 51, 52 which grip the flat portion of the cap while a cylindrical part 53 co-operates with an annular punch 54 to shape the cap and roll the rim (973), Fig. 5 (not shown), inwards. The formed cap is fed to a rotating plate 61 whereon the interior of the cap has pasty material applied to it by a needle 62, as the table rotates. The cap is then fed to a furnace 7 wherein the pasty material is remelted.
