Title: Improvements relating to the mounting of heat radiating elements or filaments
IPC: F24C15/24
Filed: 1940-02-09
Abstract: 537,897. Electric radiators; gas fires. CANNON IRON FOUNDRIES. Ltd., CLAYTON, R. T., and OATLEY, A. F. Feb. 9, 1940, No. 2490. [Classes 39 (iii) and 126] Heat radiating elements or filaments in gas fires or electric radiators are mounted with the aid of a heat responsive member which bends when heated in order to impose a tension on the heated element. As applied to a gas fire, a radiating element comprises a helix c of fine wire threaded on a further helix b which is loosely wound on a heat-resisting wire or rod d. The rod is supported between end walls e carrying a reflector f. One end carries a collar h adjacent to the free end of a bimetallic strip j which is secured to the wall e. The element is heated by a burner a, and is prevented from sagging by tension applied by the strip j when hot. The strip may be protected from direct heat from the burner by a baffle.

Filed: 1955-01-28
Abstract: Styrene polymers and copolymers having high heat-distortion temperature are prepared by heating, preferably in the absence of oxygen, at 90 DEG  to 160 DEG  C. under a pressure of at least 10,000 lb. per square inch until at least 90 per cent of the monomer or monomers have polymerized, and continuing the polymerization above 170 DEG  C. under a pressure of at least 10,000 lb. per square inch until the unreacted monomer content is less than 1.5 per cent of the product.  Two or more different temperatures and pressures may be used in either stage.  Polymerization is preferably effected in bulk but solvent, suspension or emulsion systems may be used. Polymerization is preferably conducted in the absence of a catalyst, but hydrogen peroxide, benzoyl peroxide, tertiary-butyl hydroperoxide, cumene hydroperoxide, potassium persulphate or a ,a 1-zao bis-isobutyronitrile may be used. Specified co-monomers are butadiene, a -methylstyrene, vinyltoluene, vinylxylene, ethylene, ethyl acrylate and acrylonitrile.  Other polymeric materials, plasticizers, dyes, fillers and pigments may be added and the product moulded.  In an example styrene is polymerized in an electrically heated stainless steel bomb which is charged, sealed, cooled to - 78 DEG  C., evacuated, placed in a shaker-heating jacket combination and connected to a high-pressure water system automatically controlled to maintain operating pressure \sB 1500 lb. per square inch, completion of polymerization being indicated by the cessation of intermittent pumping action.

Abstract: 691,566. Eddy-current brakes. EATON MANUFACTURING CO. Feb. 5, 1951, No. 2791/51. Class 35. [Also in Group XIII] A heat-boosting apparatus for a liquid-cooled vehicle engine 12 comprises a power-absorption device 37 driven by a power-transmitting element, such as 14, of the engine, and having an electromagnetic device comprising a rotor 16 and a stationary drum in the form of a fluid jacket 36, a fluid-circulating system connecting the jacket with the cooling-system of the engine and hand or foot-operated means for controlling the device being provided. In the construction shown, the rotor includes two annular members 20, 22, encircling an electromagnetic coil 26 and mounted on a hub 24 of the shaft 14. The coil is supplied with current, upon the initial depression of a pedal device associated with the pedal of the main braking system of the vehicle, by a brush 28, and the members 20, 22, which form the field body of the unit, are each provided with pole arms 32. Thus, upon the initial depression of the pedal the coil is energized and the eddy currents set up between the rotor and jacket 36 not only provide an auxiliary braking system for the vehicle but serve to heat the fluid in the jacket. The circulating system includes a pump 51, conduits 42, 44, radiator 48, thermostat 53 with a connection 57 to the radiator and by-pass connection 58 to the conduit 42, and a bleed conduit 59 leading from jacket 36 to the thermostat to provide a quick response of the latter, all these elements being arranged as shown and the liquid being circulated through the system as indicated by the arrows. In a modification, Fig. 11 (not shown), the pump and thermostat are arranged in a different manner, the thermostat, which has no by-pass in this case, being located between the engine block and radiator inlet, and the pump being between the radiator outlet and the inlet of unit 37.

Abstract: 1,214,811. Extruding. LOW MOOR FINE STEELS Ltd. 10 April, 1968 [19 Jan., 1967], No. 2833/67. Heading B3P. [Also in Division F2] The apparatus for coating an extrusion billet with refractory lubricant has a guideway 10 for a heated billet and a hopper 18 containing refractory material. The hopper is mounted for movement above the guideway and the refractory material is sprinkled on the billet when it rolls along the guideway towards a container (not shown) of an extrusion press, excess refractory material falling through or between the guideway 14. The hopper 18 is mounted on a carriage 20 which has a pair of side-plates 22 connected together by tie-bars 24, 26 and provided with wheels 28, the latter being mounted on rails 30 carried by the guideway 10. The hopper is vibrated by means of followers 36 which are actuated by ratchet wheels 38 and act against lugs 34 attached to the hopper; the ratchet wheels 38 being attached to the rearward pair of wheels 28 and springs 40 urging the followers into engagement with said ratchet wheels. A billet-retainer assembly is connected to the carriage 20 and has a pair of arms 42 with a shaft 44 therebetween. The shaft 44 carriers discs 46 with spacers 48 therebetween. The arms 42 are pivotally connected to the side plates 22 at 50 and are provided with notches which are engaged by plungers 52. In use a heated billet is pushed off a conveyer 14 by means (not shown) and, on release of a manuallyactuated wheel-stop 64, the billet contacts the discs 46 of the billet-retaining assembly so as to push the carriage 20 towards the extrusion press. The billet is sprinkled with refractory material and, when collars 54 which are carried at the lower ends of the plungers 52 of the billetretainer assembly are received in pockets 56 in the guideway 10, the billet-retainer assembly is released and is pivoted upwardly by the billet. The latter is now free and rolls into a trough 16 for subsequent movement into the container (not shown) of an extrusion press. The guideway 10 is raised, as indicated by the chaindotted lines in Fig. 1, to return the hopper by gravity. Shock-absorbing means to arrest the return movement of the hopper comprises springs 58 mounted on rods 60, lugs 23 on the carriage 20 engaging stops 62 on the rods 60 to compress said springs 58.

Abstract: 568,993. Typewriters &c. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and ORRIN, P. F. Feb. 16, 1944, No. 2901. [Class 100 (iv)] In a machine for printing values in figures and words on cheques or the like, of the kind comprising a " figure " type-roller 10u and a " word " roller 10l, the elements of which are coupled together and set by means of slidable bars through gear - trains, and wherein the platen 5 is moved to effect the printing,electromagnet devices are provided for operating the platen. The type-rollers are aligned by means of pins 28u, 28l engaging the depressions between adjacent type, the pins being carried by arms 9u, 9l normally held in inoperative position by a spring 11 and moved apart to engage the depressions by a pin 8 on the platen as the latter moves to printing position. If the rollers have not been correctly set, movement of the pins 28 and, therefore, of the pin 8, is limited and the platen cannot move to printing position. A bracket 12 on the platen carries a pawl 13 adapted to engage either of two ratchet wheels 15u, 15l so as to reverse the feed of the ink ribbon. A spring 14 normally holds the pawl 13 in engagement with the wheel 15u, but operation of an arm 16 depresses the spring and causes the pawl to engage the wheel 15l. The ink ribbon is thickened at each end so as to co-operate with contacts closing a circuit including a lamp bulb 22 in order to warn the operator that the feed of the ink ribbon requires reversing. The platen 5 is attached by rods 24 to the movable core of an electromagnet 4, the rods passing through the fixed core 3. Depression of a button 1 causes energization of the electromagnet to effect the printing, and springs 18 subsequently retract the platen. A pad 27 acts as a shock absorber.
