Title: Improvements in or relating to the intermittent or stepwise driving of shafts, wheels and the like
IPC: B41J1/32
Filed: 1926-12-01
Abstract: 273,648. Siemens & Halske Akt.-Ges. June 29, 1926, [Convention date]. Addition to 253,528. Type-printing telegraphs.-The apparatus described and claimed in the parent Specification for imparting a step-by-step drive to a selector shaft is modified to enable the shaft to be locked in a definite initial position when the series of selections is completed, e.g. upon completion of the message. Upon commencing a message a continuous current is sent from the transmitter and operates a neutral relay 1 to close the circuit of a magnet 8 for operating a lever 9 thus withdrawing a projection 40 on the lever from a recess 43 in a disc 41 on the selector shaft 33, and closing at 13 the circuit of the motor 19. The received impulses then operate a polarized relay 2 and the movements of the armature 25 of this relay serve to charge and discharge a condenser 24, over circuits which include a contact 17 and the clutch magnet 20, to maintain this magnet energized. Upon completion of the message the continuous current is switched off and the armature 4 and 25 of the relays 1 and 2 respectively take the positions shown. The circuit of the magnet 8 is thus broken at contact 5 and the lever 9 is moved by a spring 10 to hold the projection 40 against the disc 41 in readiness to engage the recess 43. This movement of the lever 9 enables a contact spring 14 to open the contact at 17 and to close at 16 a circuit for maintaining the clutch magnet 20 energized by a steady current. The further movement of the lever 9 due to engagemont of the projection 40 in the recess 43 actuates a contact spring 11 to open at 13 the circuits of the magnet 20 and the motor 19.
Patent GB-845507-A (GB)
Title: Improvements in or relating to a method and apparatus for sorting articles
IPC: B23Q7/12
Filed: 1955-10-25
Abstract: Articles of differing hardness, e.g. shelled and unshelled nuts, are segregated by impaling the softer one on thisel- or needle-like elements resiliently mounted in a rotatable carrier and transferring the impaled articles to a delivery position, the articles being fed to the needles by a relatively movable support, such as a conveyer belt, and the needles being displaceable in a plane perpendicular to the support on engaging a harder article. The rotatable carrier may be a drum or a disc and the needle-like elements are spring loaded or loaded pneumatically, e.g. by a resilient inflated bladder within the drum engaging their inner ends.  In one arrangement a conveyer moves the articles past a needle disc mounted on an inclined arm and having a pulley on each side whereby it is driven by belts from a rotating shaft, the belts also serving to remove the impaled nuts from the needles and, if suitably indicated, to carry them to the shoot.  A number of such belts may be arranged across the width of a needle drum and several drums may be spaced along the length of the conveyer, which itself may be resilient, e.g. of foam rubber, or resiliently supported.  The Provisional Specification also states that the rotatable drums may be counterbalanced or spring of pneumatically loaded.

In the latter position a projection on the sleeve member engages a shoulder on the key member preventing further angular movement except in the direction to secure the key member against axial movement. The device is applicable to a Bowden cable 17 controlling a choke or heater of a vehicle.

Abstract: 1342519 Refrigerator cabinets WESTING- HOUSE ELECTRIC CORP 5 July 1971 [31 Aug 1970] 31457/71 Heading F4H A heat-insulated cabinet, e.g. for a refrigerator comprises an outer shell 18, 20, open at one side and an inner liner nested in the outer shell to provide a space to be filled with foamed thermal insulation, the liner 26 and the outer shell 18 being joined along edge portions at the open side, the joint being sealed by a gas-pervious seal 50 which allows air to escape from the space when it is being filled with foam, but which prevents escape of the foam. The outer shell is constructed of a single U- shaped member 18 forming the top and sides, and an L-shaped plate 20 forming the back and bottom. The edges of the member 18 are bent to provide a channel receiving the flanged edge of plate 20. Flange 30 of plate 18 has a piece 32 folded back to provide the bottom 38 and the opposite wall 42 of the channel. The channel is filled with an impervious seal 48 which is compressed by the flange 52 of the plate 20 during assembly. The other edge of the member 18 is formed with a similar channel to receive the cranked edge 54, 56 of the inner liner. The seal 50 is a pervious material, e.g. open-celled polyurethane foam or glass fibre, which is only slightly compressed by the edge of the liner. During the foaming operation the cabinet is turned so that the open side is uppermost, and the foam is introduced through holes in the back plate 20. As the foam fills the cavity, air escapes through the pervious seal. Reference has been directed by the Comptroller to Specification 1,233,807.

Title: Improvements in the preparation of alkyl or dialkyl carbamyl halides
IPC: C07C271/04
Filed: 1963-08-12
Abstract: Alkyl or dialkyl carbamyl halides are prepared by passing a gaseous mixture of an alkyl or dialkyl-amine and a carbonyl halide through a reaction zone at a temperature greater than 90 DEG  C. and rapidly cooling the mixture containing the carbamyl halide formed and leaving said zone by absorption in an inert liquid cooling medium at a temperature of less than 90 DEG  C.  The cooling liquid may be a solvent for the carbamyl product, for example a halogenated and/or hydrogenated aliphatic hydrocarbon, or a liquid which, whilst dissolving the product slightly or not at all, is capable of maintaining it in suspension.  The process may be performed continuously and, when the cooling liquid is a solvent for the product, the carbamyl halide may be extracted by crystallization from its solution in the liquid and the mother liquid so obtained recycled to the absorption stage.
