Title: Improvements in or relating to temperature regulating devices
IPC: H01H35/26
Filed: 1936-11-20
Abstract: 487,671. Thermally-controlled switches and valves for refrigerators. ELECTROLUX, Ltd. Nov. 20, 1936, No. 31834. Convention date, Nov. 21, 1935. [Class 38 (v)] [Also in Group XXIX] A refrigerator is controlled by a thermallycontrolled switch or valve which can be adjusted not only to vary the temperature of maintenance but also to give special defrosting ' or ' rapid ice production' conditions which are then automatically terminated when the defrosting or the ice production has been completed. This is accomplished by providing the bellows 15 or other thermal element of the switch with pins or armatures 23, 26 one or other of which is adapted to be attracted and held by a magnet NS until the rising or falling temperature due, respectively, to the completion of defrosting or ice-making causes the expansion or contraction of the fluid within the bellows to bring about the exertion of sufficient force to force the pin 23 or 26 away from the magnet. The bellows acts through a lostmotion arrangement of two springs 21, 22 on a rod 20 connected with a lever 13 which operates a mercury switch within a casing 12. Adjustment is effected by rotating a cap 17 which by means of its screw-thread engagement with the end 16 of the bellows causes the longitudinal movement of the end 16. The extreme rotary positions of the cap 17 are the ' defrosting ' and ' ice-making ' positions, and rotation to either of these positions brings the pin 23 or 26 into engagement with the magnet NS. The cap 17 is then immediately rotated back to the temperature of maintenance desired after completion of the defrosting but this has no effect on the switch since the pin 23 or 26 is held by the magnet. The magnet NS may be in the form of a ring with or without an air gap and further adjustment is produced by rotating it so that the magnetic force on the pin is varied.

In an alternative arrangement, Fig. 3 (not shown) the two switches FETI, FET2 are operated by the complementary outputs from a single bistable (FF3) and the switch FET3 is actuated when the count exceeds a predetermined number.

Title: Improvements relating to conveyors
Inventor: CADMAN HUBERT WILLIAM
IPC: B65G37/00
Filed: 1958-10-07
Abstract: 872,480. Endless conveyers. SOVEX Ltd. Sept. 22, 1959 [Oct. 7, 1958], No. 31924/58. Class 78 (1). In a conveyer composed of at least one upwardly or downwardly moving steeplyinclined or vertical endless band against which articles are pressed, or which is pressed against the articles being conveyed, by a fluid-filled flexible envelope, an idler roller over which the band passes at the feed or delivery point is made yieldable so as to relieve pressure on the articles at this point. In one embodiment, Fig. 1, a pair of endless bands 1, 2 are arranged to provide adjacent upwardly moving flights between which the articles are gripped, the band 1 being pressed towards the band 2 to grip the articles by a porous flexible bag 3 which is supplied with air from a blower to maintain a predetermined pressure. The band 2 is deflected at its upper end to form a delivery platform 7 for the articles. The band 1 at its upper end passes over a pulley 10 carried on a spindle 15 which has pinions at its ends meshing with racks 12. As a result when an article is being discharged the roller 10 yields upwardly along the racks 12, returning by its own weight after the article has been discharged. In a second embodiment, Fig. 3, the articles are discharged over the top of the bag 3 by deflecting the band 1 over a roller 110 to form a platform 107. The roller 110 is carried between a pair of endless chains 118 passing over sprocket wheels 119, 120, a second roller 117 also being carried between the chains over which the return run of band 1 passes. A weight suspended on a cable 121 acts on the sprockets 119 to maintain roller 110 adjacent the band 2. When an article is discharged rollers 110, 117 move towards positions 110<SP>1</SP>, 117<SP>1</SP> relieving pressure on the article and at the same time maintaining tension in band 1. A belt 123 is suspended from the chain 118 to protect the bag 3 from direct contact with the belt 1. Specification 801,447 is referred to.

Abstract: Plasticised mixtures of thermoplastic polymers of ethylenically unsaturated compounds are prepared by a method wherein the polymer and other powdery constituents, if any, are charged into a blender with fast rotating stirring means, for example a rotor, which transforms the entire charge into a fluidised state, a liquid plasticiser and other liquid constituents, if any, are added gradually, the charge is heated to a temperature below the gelling temperature of the mixture by the energy introduced by the rotor, and finally the product is discharged as a dry powder.  The polymers are preferably those prepared by emulsion polymerisation and may be polyvinyl chloride or copolymers of vinyl chloride with vinyl acetate or vinylidene chloride.  The plasticiser may be dioctyl phthalate, dibutyl phthalate, tricresyl phosphate, dioctyl adipate or dioctyl sebacate.  Kaolin, calcined clay, calcium carbonate, titanium dioxide, stearic acid, tribasic lead sulphate, barium stearate and cadmium stearate may also be added.

Title: Circuit arrangement for reducing the electrical power fed to a utilisation means from a supply
IPC: B60Q1/26
Filed: 1972-07-13
Abstract: 1400493 Road vehicle signalling systems TEXAS INSTRUMENTS Ltd 13 July 1972 32746/72 Heading G4Q A vehicle lighting system includes a circuit which enables lamps such as direction indicator lamps IL, IR and brake lamps BL to be operated at reduced intensity when a light switch LS is closed to illuminate the vehicle lights L. The vehicle is provided with a three phase alternator having armature windings A. During daylight, switches LSA and LSB controlled by the switch LS are closed and open respectively. When a turn is to be indicated a switch SA is operated to energize the right or left indicator lamp IR or IL, the switch SA also closing a switch SB to energize a flasher unit IF. Since a transistor TRA is short circuited by the switch LSA the indicator lamp is operated at full power. At night however when the switch LS is closed thereby changing over the switches LSA, LSB, the transistor TRA is only conductive during the negative half cycles of the alternator output so that the power fed to the lamp is halved. The positive half cycles of the alternator output switch on a transistor TRB so that the current supplied by the flasher unit to conductor J is not altered during night time operation thereby preventing a change in the lamp flashing frequency. Similarly, reduction of the power fed to the brake lamps BL is reduced at night by a transistor TRC shunted by a switch LSC which is opened when the switch LS is closed.
