Abstract: 125,703. Forbes, Sir C. S. March 25, 1918. Hatching and rearing appliances.-An electric heater for use with different voltages, and applicable particularly to hatching &c. appliances, as described in Specifications 3847/15 and 122,457, comprises two separate units 4, 5, each having two windings 7, 8, 9, 10 connected by wires 11, 12. The free ends of the windings are connected to terminals 13, 14, 15, 16, 17, a switch 22 enabling the windings to be connected in series or parallel for high and low voltages respectively. A thermostatic regulator 19 connected between the terminals 17, 13 keeps the temperature constant by cutting in and out certain of the windings. When the parts are in the positions shown in Fig. 1, the current flows through the windings 8, 10, the windings 7, 9 being short-circuited through the terminal 16 and regulator 19. When the regulator capsule expands and breaks the contact between 20, 21, the windings 7, 9 are thrown into circuit in series with the windings 8, 10. For low voltages the switch 22 is moved to the position shown by dotted lines. When the regulator 19 is in the position shown, the two windings 7, 9 and 8, 10 are in parallel, the opening of the regulator by excessive heat cutting out the windings 7, 9. Additional heating-units constantly in circuit may also be employed. These are joined in parallel with the main circuit 23, 24 so as to be unaffected by the regulator or the switch 22. In another modification the regulator is arranged to affect one of the heating-elements 4, 5. A pilot lamp 39 may be included in the circuit to illuminate the interview of the apparatus to be heated, and also to indicate by its brilliancy the position of the regulator and switch 22. A switch 41 enables the lamp to be lit when the heating elements are cut out. When the apparatus is used in incubators, all the connexions are placed under an insulating lining on the cover, the heating-elements being suspended by means of rods. An egg-testing lamp may also be provided.

Filed: 1930-02-17
Abstract: 344,193. Fuel pumps. PLANE, J. H., 48, Ryhall Road, Stamford, Lincolnshire. Feb. 17, 1930, No. 5338. [Class 102 (i).] Liquid fuel for an internal-combustion engine enters a pump chamber 19 through a radial port 2 1 in a reciprocating sleeve 5, as the latter reach es the end of its stroke, and is forced through an axial passage 17 in a fixed plunger 16 to a non- return valve 33 and thence to a chamber 44 surrounding the needle-valve 45 of an injector 46. The delivery of the pump may be regulated by rotating the sleeve 5 until a port in the sleeve having a helical edge 22 is brought into register with a radial port 18 in the stationary member 16. A variable amount of fuel, depending on the rotation of the sleeve, is thus byepassed through the port and a passage 23 back into the filter chamber 2. Rotation of the reciprocating sleeve 5 is effected by a toothed member 26 which engages the lower end of the sleeve through dogs 24, the member 26 being rotated by a hand or governor-controlled transversely movable rack 35.

Title: Improvements in and relating to power transmission systems for transmitting progressively variable drive
IPC: F16D67/00
Filed: 1934-02-20
Abstract: 435,389. Hydro-mechanical variablespeed gearing. SWAN, J. G., 14, Old Square, Lincoln's Inn, London. Feb. 20, 1934, No. 5626. [Class 80 (ii)] Comprises a combination of a Vulcantype hydraulic coupling with an epicyclic train arranged to prevent undesirably rapid variations in the torque transmitted when filling or emptying the coupling. Two epicyclic elements 28, 8, Fig. 4, are connected to a vaned coupling member 9 fast on a driving- shaft 1 and to a loose coupling member 10, respectively. The third epicyclic element 3 is fast on a driven shaft 2. The arrangement is such that, during transmission, the loose coupling member 10, that is the one not coupled to the driving-shaft 1, is caused to rotate in the same direction as the driving- shaft irrespective of the speed of the driven shaft 2. The slip in the coupling in the arrangement of Fig. 4 is 50 per cent when the driven shaft is stalled, the loose coupling member 10 rotates faster than the driving- member 9, and the torque in the coupling is less than that transmitted. Means for emptying and filling the coupling when rotating is essential to the invention. Drain ports 16 are controlled by a ring valve 17 moved axially by suitable means. Filling is controlled by a valve 18 in a duct leading to an annular channel 19. Radial ports 21 in the shaft 1 communicate with an axial bore 22 which leads to radial ports 23 opening within a sleeve 13 which connects the coupling member 10 to the gear element 8. Radial ports 24 then lead liquid into the coupling. Air vents 25 assist rapid emptying and filling. In Fig. 3 is shown a form in which the planet carrier 28 is secured to the loose coupling member 10 instead of to the driving coupling member 9 as in Fig. 4. In this form, the slip in the coupling is 40 per cent when the driven shaft 2 is stalled, the loose coupling member 10 rotates slower than the driving-member 9, and the torque in the coupling is greater than that transmitted, so that the coupling is made large. A form in which the epicyclic train comprises interengaging spur gears is also described. Specifications 384,022 and 402,185, [both in Group XXIX], are referred to.
Patent GB-865013-A (GB)
Title: Process for obtaining volatile fluorine compounds and for purifying metallic or carbide melts
IPC: C01B31/30
Filed: 1958-02-21
Abstract: Undesirable impurities, such as C, Si, P, S and As, are removed from molten carbides by <PICT:0865013/III/1> <PICT:0865013/III/2> pouring the melt on to one or more calcined fluorides, other than alkali metal fluorides, which may be preheated or melted, the impurities being removed as volatile fluorine compounds.  As shown, the reaction is carried out in a rotatable and tiltable electric arc furnace 7 having a gas-tight cover 9 and attached sleeve 10 which may be raised and lowered and which allows the furnace to rotate independently of it, central telescopic pipes 12 and 13 being provided as an exhaust for volatile products which may be recovered and an opening 10a in the side of the cover to allow the introduction of the melt.  HF present in the exhaust gases may be neutralized by blowing finely divided CaO into the gases.  In the position shown in Fig. 1 the cover 9 is lowered and the furnace is closed for heating of the fluoride, e.g. CaF2, charge 16 and in Fig. 2 the cover is raised to allow insertion of the feed 2 for the melt, which is preferably introduced as a stream at 75 cm. wide as the furnace is rotated by mechanism 8.  The purified carbide is then tapped by tilting the furnace.  No slag is formed during the purification of calcium carbide and if the proportion of CaF2 is kept small, purified calcium carbide is recovered whilst large amounts of CaF2 promote the formation of CF4 which is wholly or in part obtained from the carbide.
