Title: Electromagnetic clutch
IPC: F16D65/14
Filed: 1972-03-16
Abstract: 1348354 Electromagnetic clutches; clutch/brake combinations; disc brakes BENDIX CORP 16 March 1972 [31 March 1971 (4)] 12453/72 Headings F2C F2L and F2E In an electromagnetic clutch a stationary electromagnet 95 or 116 when energized moves an armature 14 or 154 towards it to engage the clutch, there being a clutch engaging member 60 or 160 mounted on the armature such that relative rotation between the armature and the clutch engaging member causes adjustment for wear to take place automatically. In the clutch of Fig. 2 the driving member is a pulley 13 to which a friction ring 60 is attached by diaphragm spring 40, this ring 60 being attached to armature 14 by a screw thread. On energization of magnet 95 armature 14 is drawn to the output member 12 and if any wear has occurred of friction ring 60 such that armature 14 contacts the output member before the cone clutch 70, 62 is engaged then the difference in speed between members 14 and 60 causes the friction ring 60 to be screwed towards the surface 72 to engage the clutch. A drag ring 68 ensures that this adjustment is maintained and a cone brake formed by members 80 and 90 is also provided, operated by the return spring 40 of the clutch. In a further embodiment the clutch is a disc clutch, having discs 134 and 136 (Fig. 5) the member equivalent to friction ring 60 being a presser member 160 attached to the output member 130 of the clutch as is armature 154. The connection between armature 154 and member 160 may be the screw thread as illustrated in Fig. 2 (Fig. 3, not shown) but it is also possible to have pins 182 of the armature 154 which coact with cam surfaces 185 of the member 160 to cause the axial movement of member 160 on armature 154 when the armature 154 contacts a surface of the input member 122 before engagement of the clutch. Disengagement of the clutch is achieved by tension springs 186, but these may be replaced by compression springs in pockets in the driving member or by an annular permanent magnet (or a set of magnets) on the surface of the driven member 138 facing the armature. The invention may be incorporated in a motor vehicle air conditioning system, to drive a fan. In Fig. 2 the friction ring may be of organic friction material.

Title: A process for reducing the liquid-contents of materials, which have many capillary spaces
IPC: C10F5/00
Filed: 1930-04-28
Abstract: A process for removing liquid from material containing many capillary spaces consists in bringing into contact with the draining surface of the mass under treatment a heated liquid, other than the liquid to be removed, and simultaneously subjecting the mass to mechanical pressure.  The removal of the liquid may be promoted by cooling the interior of the mass at one or more points.  The process is applicable for separating water from peat or coal mud, oil from oil seeds, and sugar juice from cane or beets.  The heated liquid may be an acid or salt solution.  In dealing with oil seeds it may be a solvent such as benzine, and in extracting sugar juice a concentrated sugar solution may be used. Apparatus is described comprising a vessel with a perforated wall along which hot liquid is passed, the mass within being pressed by a plunger which carries a number of small tubes through which a cooling liquid is circulated.ALSO:A process for removing liquid from material containing many capillary spaces, stated to be applicable for removing sugar juice from cane or beets, consists in bringing into contact with the draining surface of the mass under treatment a heated liquid, other than the liquid to be removed, and simultaneously subjecting the mass to mechanical pressure.

Title: Filter for removing ice crystals from hydrocarbon liquids
IPC: B01D29/00
Filed: 1949-05-16
Abstract: 660,863. Filters. FRAM CORPORATION. May 16, 1949, No. 12984/49. Class 46 A filter for the separation of ice crystals from liquid hydrocarbons such as kerosene or gasoline fuel oils comprises a flexible filtering element, which is hydrophobic but permeable to the hydrocarbon liquid and is such that when accumulation of ice crystals on the element obstructs flow of liquid through the element, the element on account of increased differential pressure thereacross will flex and dislodge the ice crystals therefrom. As shown braided fibre glass tubes 17 treated with some water and ice repellent chemical such as a silicone or a stearate such as barium stearate, are located in a chamber 10 between the inlet conduit 15 and outlet conduit 14 across which a differential pressure is maintained. The tubes 17 are preferably collapsable and sufficiently elastic to regain their shape after collapsing and are provided with means such as weights 22 to rock the filters in the chamber by virtue of the passage of liquid through the chamber. Each tube 17 may alternatively or additionally be provided with a pin extending outwardly from its surface and/or with a plate at its lower end to cause the swinging movement of the tube. Due to the accumulation of ice thereon the tubes collapse, thereby breaking the ice which action is assisted by the swinging movement of the tubes, the ice dropping to the bottom 25 of the chamber. At this location a heater 26 is installed to supply sufficient heat to melt the ice thus formed that the resulting water may be drawn off through the valve 27.

Title: Improvements in automatic and semi-automatic telephony
IPC: H04Q3/42
Filed: 1925-05-18
Abstract: 257,008. Standard Telephones & Cables, Ltd., (formerly Western Electric , Co., Ltd.), Moir, R. A., and Hartley, G. C. May 18, 1925. Semi-automatic exchange systems.-In a system in which the relay group which controls the association of a coder with the outgoing end of a junction to a manual exchange is held from the previous selector and provides a through metallic connection during conversation, this through connection is not completed until the call has been attended to at the distant manual exchange and battery is fed back over the trunk. Provision is also made by which, if release takes place during the transmission of code impulses, the relay group is marked busy until such transmission is completed. Normal operation. When the relay group is seized, relays A, BA operate. Relay S operating over its lower winding and contacts K10, BA5 connects the stepping magnet DM of the coderselecting switch in series with relay K, the midpoint of this circuit being connected to the test wiper CR. When an idle coder is found relay K operates and opens the circuit of the lower winding of relay S but at the same time connects the upper winding to the impulsing lead P to which battery is normally connected, so that relay S is maintained energized. Relay CF is now energized and reverses the connection to the incoming line wires, thus causing the main registercontroller (of the code-translating type) to commence the sending out of impulses. These are repeated by relay A over wiper P to the coder, from which they are retransmitted as code impulses. When the retransmission is completed, the coder connects earth over wiper P which operates relay CZ. Relay B is now bridged across the outgoing leads so that as soon as battery and earth are connected to these leads from the cord-circuit at the manual end, relay B operates and energizes relay CT which completes a through metallic connection. During conversation, relays CT, CZ remain locked to the conductor RT. Premature release. If release occurs whilst the code impulses are being sent, the test wiper CR is earthed from the coder and this earth is extended over contacts S10, K26 to replace that removed by the opening of contacts BA5. The relay group is marked busy over contacts CT7, CF7, S12, K10. When code sending is completed. the earth over wiper CR is removed and relay K releases, but relay B operates over the lower outgoing conductor and maintains earth on the conductor RT until the call is cleared at the manual end. Faulty coder. If battery is not found on the impulsing lead by wiper P, relay S releases and completes a circuit for magnet DM over contacts S6, CZ6, BA5. Relay K also releases and remakes the circuit of relay S which opens the magnet circuit. The switch advances a step and hunting is thus resumed until a code which is both idle and non-faulty is seized. Specification 254,046 is referred to.
