Title: Improvements in and relating to the refining of oxidised steels and the manufacture of alloy steels
IPC: C21C7/00
Filed: 1947-07-08
Abstract: In a refining process for steel which may contain a high proportion of impurities, e.g. sulphur and phosphorus, and which has been subjected to an oxidizing treatment, the molten steel is mixed with a quantity of liquid aluminium in amount dependent on the oxygen content of the steel and sufficient to deoxidize and quieten the steel completely and immediately by aluminothermic reduction.  The liquid steel may be poured into a bath of aluminium which may or may not contain fluxes, e.g. lime, soda, silica, or manganese oxide, which may be liquid or granular, in the latter case heated to 1,000-1,500 DEG C.  The refined steel may then be poured into a liquid bath containing one or more alloying elements, Cr, Ni, Co, Mo, V, W, Al, Sb, Cu, U and Zr and/or C, Si, or Mn.  The unrefined steel may be poured into a bath containing the alloying elements in liquid condition and having an overlying layer of liquid Al; if the latter is to be included as an alloying element it should be present in excess of that required for the refining operation.  When Al is the only alloying element the steel is poured into a bath containing an excess of Al over that required for the refining operation. Specification 18962/09, [Class 72] is referred to.

Filed: 1939-06-20
Abstract: 533,843. Lamp holders. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT. W. J. June 20, 1939, No. 17982. [Class 38 (i)] [Also in Group XXXV] A holder for a tubular discharge device having a pair of contact pins on each end cap, is so connected to a supply circuit that its contacts are fully energized only when both pairs of lamp contacts are inserted in the holder. An autotransformer used to supply the current has its primary circuit 6 completed through one filament 4 when that end of the lamp 3 is inserted but contact by the operator with the other end 5 of the lamp can only apply the mains voltage to it, one end of the primary being earthed, which is insufficient to produce a harmful discharge. If the other end 5 of the lamp is inserted the primary is not completed. Other similar circuits are described which may have a condenser in series with the primarycircuit to produce resonance.

Title: Improvements in circuit arrangements for electric discharge devices
IPC: H05B41/34
Filed: 1938-06-20
Abstract: 505,143. Supply systems for discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. June 20, 1938, .No. 18283. Con vention date, June 19, 1937. [Class 38 (iv)] A circuit arrangement for the production of periodic flashes of high intensity comprises an inductor 9, Fig. 1, for initiating the ignition of a discharge lamp 1 which is flashed by the discharge of a condenser 3 in a circuit comprising a rectifier 2, discharge lamp 1 and a choke 7, the condenser 3 being charged up through a rectifier 4 in the secondary circuit of a transformer 6. The rectifier 2 may consist of a mercury vapour rectifier with liquid cathode as shown, or, provided the voltage and condenser capacity are not too large, a discharge tube with incandescent cathode may be used. The rectifier 4 has preferably an incandescent cathode and a vapour or gas filling. A rectifier S, also with incandescent cathode, is provided to prevent the discharge of the condenser 3 through the coil of the ignition inductor 9. For the production of especially short flashes for stroboscopical observation or photographic exposure, the choke 7 may be omitted. The resistance 5 in the secondary circuit of the trans. former 6 may be made predominantly inductive, whereby the condenser 3 is charged up to a voltage substantially above the peak voltage of the transformer secondary winding. The control of the discharge is facilitated by the provision of one or more grids in the rectifier 2. Fig. 2 shows a form wherein three grids G<1>-G<2> are provided, connected in the secondary circuit of a transformer 11, the primary of which is connected in a circuit 10 in series with the primary coil of the inductor 9. If necessary a condenser may be connected across the secondary side of transformer 11 to retard the ignition of the rectifier 2 since, because the transformer 11 has to deliver a substantially smaller voltage than igniter 9, and the natural frequency of its secondary coil is greater than that of 9, the ignition voltage of the rectifier 2 would be reached sooner than that of the lamp 1. The condenser 3 is charged up through a resistance 5 from a direct current source 6. The ignition impulse may be effected in known manner by applying to the primary coil of the inductor 9 and of transformer 11 the discharge current impulse of a condenser, the discharge of which is controlled through a grid-controlled gas or vapour discharge tube.

Title: Improvements in and relating to rubber derivatives
IPC: C08C19/10
Filed: 1936-07-02
Abstract: In the production of rubber derivatives by treating a solution of rubber with a halide of an amphoteric element, gelling of the reaction mixture is minimized and the reaction time for any particular product is lessened by heating the solution to a temperature at or near its boiling point before adding the halide. The solution is preferably heated for a time sufficient to eliminate any oxygen dissolved in the rubber solution.  The rubber derivatives may be isolated by treating the reaction mixture with a large excess of water, preferably containing a reducing agent such as sodium sulphite.  Halides specified are tin tetrachloride, ferric chloride, boron fluoride, stannous chloride and titanium tetrachloride. Specification 426,565 is referred to.  According to the Specification as open to inspection under Sect. 91, hydrochloric acid may be added to the rubber solution prior to the addition of the halide.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1424699 Measuring rotary imbalance FORGES STEPHANDISES 17 April 1973 [20 April 1972] 18366/73 Heading G1X Apparatus for determining the rotary imbalance of a wheel 6 comprises a shaft 2 which is adapted to support the wheel 6 at one end and which is provided at its other end with a cylinder 12 having a helical trace 13 thereon, and a moveable pick-up 14 which is arranged to detect oscillations of the shaft 2 in a horizontal plane when the shaft is rotated and to activate a light 16 disposed to illiminate the cylinder at a predetermined phase of each shaft oscillation cycle. As shown, the shaft 2 which is supported in a bearing 3 and allowed to oscillate only in a horizontal plane, is rotated at a constant speed by a motor 10 through a pulleybelt arrangement 7, 8, 9. The wheel 6 to be tested is attached to a plate 5 rigid with the shaft 2. The pick-up is adjusted radially of the cylinder until it just touches the latter at the extremes of its oscillation in,the horizontal plane and the position of the pick-up 14 as indicated by a scale 20 against a fixed marker 22, is indicative of the magnitude of imbalance. A sighting device 25 which may comprise a pair of transparent plates provided with cross marks is slideable in the longitudinal direction of the shaft 2 and is positioned so that an observer looking through the device 25 observes the cross marks coincident with the position of the helical trace in the aforesaid horizontal plane, the helical trace appearing stationary due to the stroboscopic effect produced by the connection of the light 16 to the pick-up 14. Such position of the trace is indicative of the position of imbalance on the wheel 6. Instead of a single scale 20, a plurality of scales may be provided for use with different types of wheel. The apparatus may be provided with a braking device for the shaft 2 and may be used in the static balancing of wheels.

Filed: 1964-05-05
Abstract: 1,035,263. Loading dock. KELLEY CO. Inc. May 5, 1964, No. 18614/64. Heading B8E. An adjustable loading dock installation comprises a pivoted loading deck biased to a raised position and provided with means to raise an extension lip towards an operative position as the deck rises, to support the deck on struts or legs in a cross traffic position, to prevent accidental depression of the deck from a below dock level position and to prevent depression of the deck to gain access to the building under its door without first raising the deck. A ramp structure 12 having a deck 16 is pivoted at its rear end to a fixed structure 5 normally housed in a pit in the loading dock. Springs 25 through a lever arm 26 and cam plate 28 bias the deck to a raised position while a hold-down device 29 allows rods 30, 31 to move together but by a clutch device 33 prevents them separating and thus allowing the deck to rise. The clutch 33 may be released by a cable 35 connected to a releasing arm 34. As the deck rises a lifter 36 for a lip extension 18, by its cable connection 38 to the structure 5, raises the lip until a holding arm 39 engages it. The holding arm is released as the deck is lowered to its operative position with the lip resting on the vehicle platform. To support the deck in a cross traffic position legs 40 engage posts 41. When the lip is in an inoperative pendant position the legs 40 are biased to engage the posts 41 but they are forced to an inoperative position by engagement of abutments 46 with arms 44. When the lip is raised the deck can be lowered to an operative position below dock level when required and to prevent further accidental lowering of a deck when the vehicle leaves removing support from the lip the legs 40 are then forced against the posts 41 so that the abutments 47 become engaged therewith preventing any further depression. A modified connection between the lip and leg strut engagement mechanism, additional abutments on the legs to prevent depression of the dock from a raised position, and means to prevent disengagement of the legs and struts and depression of the dock to gain access to the building without prior raising of the deck are described.
