[Class 39 (i)] An electric discharge device, such as a lamp, operating with a readily condensible vapour of a metal, such as sodium or potassium, has the discharge space separated from the space adjacent the seal for the leading-in wires to the electrodes by a cup-shaped member 6, Fig. 1 (34336/34), the wall of which is so close to the adjacent neck 7 of the envelope of the device that the space between them can be sealed by condensed vapour to prevent deposition of the metal in the neighbourhood of the seal; the leads 3 are insulated for the greater portion of their length by insulating tubes 4, preferably of glass, and pass through grooves or channels 5 formed between the wall of the cup and the adjacent neck of the envelope, the grooves being formed either in the wall of the cup, as shown, or in the neck, or partially in both. The leads may be diametrically opposed, as shown, or, in a modification, are all embedded in a strip of glass or other insulating material, and pass through a single groove in the cup. The cup 6 may be filled with glass wool. In a further modification, the grooved cup-shaped member 2, Fig. 4 (34568/34), is sealed at its bottom end to the end of the bulb neck. The leading-in wires 5 pass through the seal and are protected by glass tubes 4. In assembling the device the cup and tubes may be held together by a band or wire. Specification 440,999 is referred to. The Second Provisional Specification describes modifications in which the protective tubes 4 are sealed into the seal between the cup-shaped member and the envelope neck, and may project through the seal, the tubes being then made of sodiumresisting glass. It is further stated that the tubes 4, Fig. 4, may be of steatite.

Title: Improvements in devices for instantaneously striking the arc in arc lamps
IPC: H05B31/30
Filed: 1927-12-20
Abstract: 282,471. Anciens Etablissements Barbier, BÚnard, et Turenne Soc. Anon. Dec. 27, 1926, [Convention date]. Arc lamps.-The motor of an arc lamp is so arranged that when the current is switched on it moves a slide carrying one of the carbons against a spring so that the carbons come into contact and the spring then strikes the arc. The motor shaft 1 drives through worm gearing a sleeve 3 running on ball-bearings surrounding a spindle 11. Arranged round the spindle is an electromagnet 6 which, when the arc is broken, draws a ring-shaped armature 5 carried on the sleeve 3 into contact with a member 7 connected to the spindle 11 by a friction clutch 8. The spindle 11 then rotates and through the gearing shown moves a slide 18 carrying the carbon 19 against a spring 22 until the carbons come into contact. The magnet 6 is then short-circuited, releasing the spindle 11 and allowing the spring 22 to strike the arc. The carbon 19 is fed in the usual way by rollers 26.

Title: Preparation of phosphorus esters
Inventor: PARKINSON ERNEST KENNETH
IPC: C07F9/141
Filed: 1965-08-13
Abstract: b -Halo-alkyl phosphate or phosphite esters are prepared by reacting a phosphorus trihalide of the formula POX3 or PX3 respectively, where X represents a halogen atom with a b -haloalcohol in the presence of a Friedel-Crafts catalyst.  The preferred alcohols are primary alcohols containing at least one halogen atom in the b -position to the hydroxy group.  The catalysts include the halides of aluminium, tin, titanium, iron, zinc and magnesium, and boron trifluoride, and are preferably freshly prepared. They may be added as such to the reaction mixture or prepared in situ by adding the appropriate metal to the reaction mixture.  The reaction may be effected by mixing the reactants in the presence of the catalyst, or an inert solvent or diluent may be used.  The reaction may be carried out at room temperature, or at temperatures of from -10 DEG  to 100 DEG  C.  It may be carried out under reflux or under reduced pressure, or an inert gas may be passed through the reaction mixture to remove hydrogen halide formed in the reaction.  Esters containing residual halogen atoms on the phosphorus atom are produced by using a stoichiometric deficiency of the halo-alcohol.  Specified alcohols are 2,3-dibromo-, 2,3-dichloro-, 2,3-di-iodo-, 2,3-difluoro-, and 2-bromopropanol, 2-chloro-, and 2-bromoethanol, and 2,3-dibromobutanol.

Dec. 22, 1931, No. 35374. [Class 74 (ii).] A stop-motion for control of warps, e.g. in a warp knitting-machine comprises parallel bars 12 reciprocating across and beneath the warps and engageable by a broken warp which thereby deflects upstanding flexible contact pins 20. The broken warp falls or is brushed by the pins 20 into the notches 13 of the bars 12. When a thread gets into a notch and is impelled laterally against the nearest pins 20 it flexes one or more of them into contact with stiff pins 22 extending from a bar 21. A circuit is thereby completed which stops the machine. The pins 20 may be replaced by pendulum-like members. Electrically-operated means, including warning lamps or bells indicating the positions of the broken warps may be incorporated.

Abstract: 857,762. Measuring radiation doses. PLESSEY CO. Ltd. Nov. 12, 1958 [Nov. 14, 1957], No. 35477/57. Class 40(3). An integrating dosemeter for ionizing radiations comprises means for integrating the output of the radiation detector and triggering a circuit when the integrated signal reaches a predetermined value, thereby actuating an electromechanical register which is driven by a transistor in the trigger circuit. In Fig. I radiation falling on a detector 1 causes current to flow into a capacitor 2 charging it to a voltage representing the integrated dose. A transistor trigger circuit 8 is biased by the filament supply battery 7, and when the capacitor voltage becomes approximately equal to this bias the electrometer valve 3 (which acts as a cathode follower) passes enough current to trigger the circuit and advance the register 9 by one unit. At the same time a relay in the register closes contacts 6 which short-circuit the capacitor 2 and enable it to receive a fresh charge. Doses less than one unit of the register are shown on a meter 4. Fig. 2 shows the trigger circuit, in which a transistor 12 is gradually driven towards cut-off as the capacitor 2 of Fig. 1 charges, and thereby allows a further transistor 13 to draw current. At a certain point the common emitter resistor 14 makes the action regenerative, transistor 13 conducts fully and the register 9 is actuated. A further transistor stage (of common collector type) may be advantageous.

When an overhead travelling crane is overloaded part of the crab 12 is tilted about a fulcrum 17 by the lifting rope 16 which passes over a pulley 14 to a winch 13. The crab runs on a bridge comprising parallel guides 10, 11, which runs on further rails at right-angles thereto. As described, two crabs are provided and tilting is limited by members 18 which abut the girders 10, 11. The invention is particularly applicable to forge cranes where an overload may be applied to the crab by a press. When this occurs a headstock 15 is depressed on supporting hydraulic jacks 19 which are connected through non-return valves to hydraulic accumulators. Further overload tilts the crab, a buffer 28 controlling its return to the horizontal. Air under pressure in the accumulators forces fluid back into the jacks 19 through throttle valves. In a practical example the jacks 19 are depressed by a 25% overload and the crab is tilted by a 50% overload. Alternatively the crabs may be arranged to tilt before the jacks 19 are depressed.
