Abstract: 1,166,797. Testing sausage skins. TEEPAK Inc. April 26, 1968 [May 2, 1967], No.19927/68. Heading G1S. Sausage casings are telescoped or shirred from a length of 160-200 feet to 20-25 inches and are tested for breakage in an apparatus comprising two semi-cylindrical end walled half shells 10, 11, Figs.3, 4 which may be pivoted by links and an actuator 28 to form a closed cylinder, a conduit 32 connected and sealed at one end to a tracer gas (helium) supply and at the other end to a deshirred portion 61 of the casing, and a rod 55 supporting the other deshirred casing end 60. In operation the gas cylinder 34 supplies helium at 1-10 p.s.i.g. to the interior of the casing through conduit 32. A gas detector 68 having a tube connected at 27 to the cylindrical chamber is connected to a source of vacuum 59 so that any tracer gas which escapes from the interior of the shirred casing through a breakage will be held within the cylindrical chamber. The vacuum applied at 27 draws air into the chamber through an opening 26 and the air is swept through the chamber into the detector, the amount of tracer gas present (if any) being registered so that the casing may be either passed or discarded.

Abstract: 972,043. Ratchet mechanism. KIENZLE UHRENFABRIKEN A.G. May 21, 1963, No. 20162/63. Heading F2Q. [Also in Division G3] Ratchet mechanism located between a periodically wound energy store and the gear train of a timepiece comprises a U-shaped wire pawl 3 mounted upon a flywheel 1 and frictionally engaging the periphery of a wheel 2. When the flywheel 1 is rotated in the direction of the arrow by a spring, the pawl 3 grips the wheel 2 and transmits drive thereto. When a reverse torque acts upon flywheel 1, for example by means of an electromagnetic system to effect winding, the pawl 3 unlocks and moves freely over the edge of the wheel 2. The pawl 3 may engage the peripheral edges 4, 5 of a circular disc 2, Fig. 2, or raised projections 4, 5 formed on toothed gears, Figs. 3 and 4.

Title: Binding machine
IPC: B65B13/06
Filed: 1962-05-25
Abstract: 1,001,385. Binding packages. SOC. BATALAM. May 25, 1962 [June 2, 1961], No. 20228/62. Heading B8C. [Also in Division B3] In a binding machine the guides for forming a ligature into a helical loop or loops around the article to be bound are formed by two separable shells 1, 2 (Fig. 5), and each shell is formed of two or more members which can be separated to release the ligature from a passageway formed in the guides. In the arrangement of Figs. 2 and 5 the shells consist of members 3, 4 and 5, 6 hinged together at 16 and 17 and opened, against the bias of springs 24, by pneumatic rams 21, 22 so that passages 8, 8<SP>1</SP>, 9, 9<SP>1</SP>, 10, 10<SP>1</SP> (Fig. 3) defined by their faces are opened to release a ligature guided through these passages to form a helical loop around a package 15 (Fig. 5) to be bound. The ligature is fed by rollers 47, 48 (Fig. 1) pressed together by springs 46 and driven through gearing 36, 37 from a motor 39. The feed is stopped when the ligature, after passing once around the guides, leaves the aperture 10<SP>1</SP> (Fig. 2) and abuts against the body of a gripper 64, 65 which is then closed. The shells are then opened by rams 30, 31, and the portions 3, 4 and 5, 6 separated as described above so that, by reversing the feed, the ligature can be drawn around the package 15. The ends of the ligature are then gripped by a twisting head 70 (Figs. 2 and 5) raised by a ram 68, and the end of the ligature is then cut off by a guillotine 57a (Fig. 5). The twisting head 70 is then rotated to twist the ends of the ligature after which a collar 71 is raised by a link 72 (Fig. 2) and ram 74 to press the end of the twisted wire against the package. In an alternative arrangement grooves 121, 123 (Fig. 14) receiving the ligature are closed by rollers 153 and spacers 154 (Fig. 15) carried by members 150a, 151a which can be moved outwardly from the shell 101, against the bias of springs 155, by rams 156, thus releasing the ligature from the grooves 121, 123. The grooves 121, 123 permit two complete turns of ligature to be made about the package, but, by adjusting one of the shells 101 along the axis of its hinge 105, one of these turns may be omitted. In this arrangement the feeding rollers for the ligature, and its driving gearing 144 and motor 145, are carried on one of the shells. The binding machine may be mounted on a mobile carriage 90 (Fig. 6) so that it can be moved to apply ligatures at several points to a bundle 15 of metal rods. The rods may be allowed to fall into binding position on the machine under the control of a gate 82, 83 operated by a ram 84. The bundles may be held in position by clamps 78 operated by rams 80, 81; and the completed bundles may be discharged by arms 86 operated by rams 87. The successive steps in operation of the machine may be controlled by a programme stored on cams, perforated tape, or on material sensed by photo-electric cells, and. the arrangement preferably permits the operator to stop and re-start the machine at any stage. The pneumatic rams may be replaced by mechanical devices.

The plate 12 and runners 5 preferably have the same outline so that they can abut the casings underside to provide a minimum cutting height in which position brackets 10 are not used and lugs 6 and 8 are directly conected together. In an alternative embodiment the runners 5 are absent and the plate 12 is adapted to be connected to the brackets 10 or the lugs 8.

Abstract: 391,651. Automatic exchange systems. R U M P F, F., 8, Schwanengasse, Berne, Switzerland. July 18, 1932, No. 20312. Convention date, July 21, 1931. Addition to 391,629. [Class 40 (iv).] In the apparatus described in the parent Specification for perforating a card in accordance with dialled numbers, the perforating operation is prevented unless the card is in the correct position. The card LK is fed from a container KS by a member N into the position shown, where it is gripped by a lever H and co-operating member M, which move it one step to theleft after each hole is punched. The card is finally ejected, and the lever H and member M return to grip a fresh card. In the normal position the lever ,H closes the contacts k and relay A operates to prepare the circuits of the switch W which associates the perforating apparatus with the recording apparatus. If no card is in position, the lever H makes contact with a spring-pressed ball x, and relay B operates, disconnecting relay A and lighting a lamp EL. When the last card is fed from the container KS, a similar contact y causes relay C to operate and light a lamp ML. An alarm AW is sounded in either case.
