Title: Improvements in processes for the removal of gases from molten metals and alloys
IPC: C22B9/04
Filed: 1933-10-19
Abstract: 425,369. Removing occluded gases by exhaustion from molten metals and alloys. RIDGE, H. M., 16, Devonshire Square, and HUNN, S. C., 23, Wenlock Road, City Road, both in London. Oct. 19, 1933, No. 25899. [Class 72] In a method of removing gases from molten metals or alloys by raising a quantity of the molter metal from a furnace through an uptake into and passing the said meta or through an exhaustec duct or chamber, the meta stream is heated by any suitable means to a temperature sufficiently above the melting point for the gases to be released freely. An uptake 3 leads from a furnace 1 to the bottom of an exhausted chamber 4 from which a downtake 5 leads to a crucible or vessel 6. When the metal is raised to the desired level in the chamber 4, the level in the crucible &c. 5 is lowered, e.g. by opening a taphole therein, so that a syphonic transfer of the metal from the furnace through the chamber 4 to the crucible 5 is produced. The uptake 3, downtake 5 and chamber 4 are heated to the temperature referred to above by means of gas jets, electrical resistances arranged on the parts 3, 4, 5, alternating current, or by enclosing the said parts in suitable casings which are traversed by flue gases. When those parts are lined with refractory metal, the electrical conductors are embedded in the refractory lining. The downtake 5 may open directly into moulds instead of the crucible 6, a slide or valve being provided in the downtake which is then extended below the level in the furnace. In a modification, the furnace is divided transversely by a partition of highly refractory material which is bridged over by a U-shaped bell or structure of similar refractory material, the upper portion of the bell &c. being connected to an evacuating device.

Title: Flush bolts
IPC: E05C1/04

Abstract: 967,947. Sliding bolts. E. HOLDEN & CO. (B'HAM) Ltd., and E. J. HOLDEN. July 2, 1963, No. 26124/63. Heading E2A. In a flush fitting bolt in which the bolt 11 is slidable relatively to a fixing plate 10, the inner end of the bolt is associated with a depressible means with which is associated a locking means which coacts with parts of the fixing plate 10 to lock the bolt both in the shot and retracted positions, but which permits of the bolt to be freed and to become actuable upon depression of the depressible means. As shown, the fixing plate is formed with a depression 104 having a slot 105 for a press knob 12 which is attached to the tail of the bolt 11 and which is loaded by a plate spring 13. The bolt tail is formed with tongues 113, 114 which, when the bolt is moved to the shot and retracted positions after depression of the knob 12 engage respectively with the rear and front ends of the slot 105. Specification 967,948 is referred to.

Title: Improvements relating to automatic electric switches

Filed: 1926-10-20
Abstract: 278,190. C.L.I. Manufacturing Co., Ltd., Watson, E. A., and Laird, J. A. Oct. 20, 1926. Electromagnetic switches.-An automatic cutout for the battery charging circuit of motor vehicles has a core or armature formed of steel capable of retaining sufficient magnetism after the existing current in the single winding has been interrupted to ensure the completion of the switching operation. As shown in Fig. 1 the case a is formed of steel and is adapted to attract the armature d so moving the contact g from the fixed contact h to the fixed contact i. The low resistance winding c is normally in series with the contacts g, h between the positive terminal of the dynamo m and earth (Fig. 4) so that when the voltage of the dynamo rises to a predetermined value the armature is attracted. On account of the magnetism retained by the core a when contacts g, h have disengaged there is no tendency for the armature to be set in vibration and the armature consequently moves over to bring contacts g, i into engagement so completing the charging circuit through the winding c. When the generator ceases to operate a reverse current flows momentarily from the battery to the generator demagnetizing the core a and permitting the armature to be moved to its original position by the spring e. In an alternative form the armature, instead of the core, is made of hard steel. Specifications 4541/10, and 29980/10 are referred to.

The alloy may also have up to 20% of one or more alloying components such as magnesium, calcium, manganese, copper, silver, cadmium, tin, gold, antimony, beryllium, silicon, barium, strontium, gallium, bismuth, indium and lead. The molten alloy is poured into a mould pre-heated to between 260 C. and 538 C. and, in one example, an iron mould may be coated with a mould wash of a graphite suspension in water, or coated with acetylene black from an acetylene flame.

Abstract: 318,493. Thompson, L. I. Sept. 3, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Openers &c.-In an arrangement for separating ,lumpy material and foreign bodies from fine material, particularly applicable to the separation of fibrous lumps and heavy particles from fine fibres in a thread separating machine, a current of air is directed on to the material in a direction opposite to that in which it is moving, whereby the fine material is carried away by the air current, whilst the heavier material falls away under the action of gravity. As applied to a thread separating machine of the kind described in Specification 270,255 the material passes from the opening discs 1 into a chamber 2. A current of air is directed through an opening 3 into the chamber and carries the fine fibres into a pipe 4 leading to a fan 5 which delivers them through a pipe 7. The heavier material falls to the bottom of the chamber.

Abstract: 444,253. Moulding and lining pipes &c. SPLATT, E. F. T., 16, The Avenue, Hampton, Victoria, Australia. Sept. 17, 1934, No. 26673. [Class 87 (ii)] Pipes, &c. are lined with or moulded from cementitious material by apparatus comprising a non-inflatable elastic core adapted to be stretched longitudinally to reduce its cross-sectional area, means for mounting said core within a pipe or mould, and devices for exerting pressure lengthwise of the core upon a sealing member to seal an end of the space surrounding the core. The cores 2 are of rubber or the like and are provided with a central bore 4 to accommodate a rod 6. One end of the rod 6 is held by a nut 12 on a wooden centring piece 8 which may be in the form of a solid block, Fig. 1, or of hollow cylindrical formation, Fig. 9. A rubber washer 13 is pressed against the end or a shoulder 9a of the pipe by the block 8. In the case of pipe bends, Fig. 1, a straight bolt 16 is screwed into the end of the curved rod 6 and is fitted with a nut 16a engaging a bracket 21 attached to the pipe fitting so that the rod 6 may be drawn tight. The core 2 projects from the end of the pipe so that it can be gripped by a clamp and a spring 24 holds it in place. When the rods 6, 16 are removed the core 2 may be withdrawn by the clamping member. In order to ensure a tight grip a plug may be inserted in the end of the bore 4. Fig. 9 shows apparatus suitable for moulding T- or cross-pieces. A major core 2b is fixed in position by a rod 6 and centring pieces 8 and one or more shorter cores 2c provided with. recessed ends which engage the core 2b are placed in the pipe branches 33 and project therefrom. The shorter cores 2c are held in place by rods 6a which are formed at their inner ends with reduced stems which screw into sockets in the rod 6. Cement is poured into the upper end 41 of the pipe and after the cores have been removed the square corners 42 of the cement are rounded off. During filling the fittings may be tilted or vibrated to remove air locks. As shown in Fig. 5, the centring member 8 may be held in place by clips 43. When moulding concrete &c. pipes the mould may be formed of two semicylindrical sections hinged together at one side and provided with fastening means on the other side.

Comparator CM1 is set if a signal S A  occurs before S B , thus indicating that the source is on the right. The signals from the two forward sensors are combined in OR gate 10 and compared to the signal S c  from the rear sensor in comparators CM2, CM3 via delays DL1, DL2. The output from CM2 indicates the source is in the front quadrant and from CM3 that the source is not in the rear quadrant.
