Abstract: 638,075. Releasable fastenings. BRITISH THOMSON-HOUSTON CO., Ltd. May 23, 1947, No. 13875. Convention date, May 23, 1946. [Class 44] [Also in Group XXIII] In a dish-washing machine (see Group XXIII) a latch 16 for a cover 7 has two arms 17, Fig. 3, by which it is rigidly attached to a handle 19 through rods 20 which pass through the cover arm 6 and are surrounded by rubber bushes 21 so that the handle and latch may. be moved relative to the cover. The latch 16 has a hook 24, Fig. 15, at its lower end which is engaged by either of two locking elements 25, 26, Fig. 13. Element 26 is keyed to a shaft 27 which is journalled in a bush fixed to the vat wall. Element 25 is rotatably mounted on a circular section of the bush between the element 26 and a plate 33 through which the bush projects and which is fixed to the vat wall. The elements 25, 26 each have an arc-shaped finger 36, 37, arranged so that their ends abut. Element 25 is biased clockwise by a spring 41 and element 26 has an actuating lever 38 keyed to its shaft 28. The finger 36 of element 25 is dimensioned so that it will pass through the. entrance of hook 24 on the latch 16. Finger 37 of element 26 has a port 44 which will pass the. hook entrance and a deeper port 45 which will not. Thus the latch 16 may be unlocked when finger 36 or port 44 of finger 37 is within the hook 24 but is locked when port 45 is in the hooks. Finger 36 is slightly deeper than port 44 so that a shoulder 46 is formed when they abut. The lever 38 is connected by a rod 139 to a slot. in a lever 136 which is pivoted on the casing 2 and which is raised when a starting button 140 is pushed downwardly so moving port 45 of locking element 26 into the hook 24 to lock the cover 7.

Title: Thermoelectric flasher arrangements
IPC: B60Q1/38
Filed: 1975-04-08
Abstract: 1493978 Thermal flasher switch WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 8 April 1975 [9 April 1974] 14364/75 Heading H1N A flasher switch comprises an element 4, biased to move in direction A but retained by a thermosensitive element 7, and a resilient switching element 1 carrying contacts 2, 3 and mechanically connected to the biased element 4 by an over-centre spring 6 which is insulated from the element 4 by a block 6a. When the switch FR is closed current flows from supply terminal 49, through the switching element 1, contacts 2, 2a, thermosensitive element 7 (which it heats and expands) and biased element 4 which is connected via a winding 8 to the lamps BL. The expansion of element 7, which is a heater wire, allows biased element 4 to move towards the switching element 1 until the spring 6 moves over-centre and snaps the element 1 across to make contact between 3 and 3a (Fig. 2, not shown). Simultaneously the current through winding 8 attracts a biased armature 11 to make contact with 2a thus providing a circuit to an indicator lamp CL. In this position the flasher lamp current no longer passes through the heater wire 7 so that the lamps glow with full brilliance until the heater cools sufficiently to separate contacts 3, 3a as the biased element 4 is drawn back, the following movement of switch element 1 being prevented by a stop 5 (Fig. 3, not shown). Further cooling and withdrawal of the heater wire results in the spring 6 and hence switch element 1 being returned to the initial position. As the timing of both light and dark periods is determined by the cooling of the heater wire, the device is virtually independent of voltage. Constructional details are given (Figs. 4 and 5, not shown).

Abstract: 183,644. Hopewell, W. C., and Stocks, B. T., (trading as Hopewell & Stocks). May 25, 1921. Lace.-Fabrics of the type described in Specification 13317/15 are adapted for use as incandescent mantle fabrics by being formed so as to present two faces independent to some extent of each other. The fabric may be made tubular. A lace machine is provided with four sets of warp bars, carrying threads 1, 2, 3, 4. The threads 1, 2 twist with alternate bobbin threads f - - f<2> while the threads 3 are tied to the same bobbin threads by the threads 4. Each thread 1 or 2 twists with its own bobbin thread and no other and the threads 1, 2 are so laid that they loop with each other as shown in Fig. 4 to give loop effects similar to those described in Specification 13317/15. The threads 3 traverse to and from alternate bobbin threads f - - f<2> while the threads 4 continually pillar with the same bobbin threads. A similar fabric may simultaneously be made from the remaining bobbin threads b - - b<2> working with other warp threads which are arranged similarly to the threads 1 - - 4 and are indicated in Fig. 1 by dotted lines. The front and the back fabrics can be united at intervals to form tubes by causing some of the threads 3 to traverse to and from adjacent bobbin threads as b, f instead of, as in making separate back and front fabrics, to and from alternate bobbin threads b, b' or f, f<1>. The tubes so formed may be joined by lacing threads. According to the Provisional Specification, tubes are formed by causing certain of the loop cross and pillar threads to weave with adjacent bobbin threads.

Title: Process for the production of submicron silicon carbide
IPC: C01B31/36
Filed: 1962-04-16
Abstract: <PICT:0956076/C1/1> Submicron particulate silicon carbide is made in a vapour phase reaction by forming an electrode containing silica and carbon, drawing a high temperature arc between the electrode and an electrode in a reaction chamber, withdrawing the reaction products from the chamber and extracting the silicon carbide therefrom.  The rod which may contain silica and carbon in stoichiometric proportions, is consumed by the arc, and vapours of silicon, oxygen and carbon are formed which give submicron silicon carbide particles. A non-oxidizing atmosphere preferably a reducing atmosphere may be maintained in the reaction chamber.  The high temperature arc may be of low intensity.  Silica and carbon may be dry mixed and then a binder, e.g. corn syrup, added whilst mixing continues.  After extrusion of the mixture to give a rod, the rod is air-dried, oven-dried and fired in a reducing atmosphere, e.g. 800 DEG  C., for 16 hrs.  In the Figure, a cylindrical gas-tight chamber 10, e.g. of brass, suitable for sub- or super-atmospheric conditions is surrounded by cooling coils 12. A consumable electrode 30, i.e. a rod of silica and carbon, is slidably mounted in a contact device 14 which device has a refractory-material face-plate 26, e.g. of boron nitride, and is mounted in a port in chamber 10 with a gastight seal 22, cooled by water manifold 24 and connected to a source of electricity.  A push-rod operated automatically or manually is used to maintain the electrode in the arc chamber.  A graphite cathode 32 is mounted in graphite bushing 34 and insulating sleeve 36, at an angle of 45 degrees below the horizontal plane of the consumable electrode.  Purge or carrier gas, e.g. argon, enters by inlets 42 while a window 44 is provided opposite the arcing area.  A duct 46 cooled by coils 50, leads to a tube 54 and on to a collection means, e.g. an electrostatic dust collector or a cyclone.  The process is initiated by first contacting the electrodes to produce ignition and then withdrawing an electrode and maintaining a constant arc gap. The product may be purified by oxidizing any excess of carbon or removing any excess of silica by leaching with acid.  The product may be used for example as an abrasive, filler, pigment, filter-media, catalyst carrier or insulation material.
