Filed: 1945-06-14
Abstract: 605,330. Fluorescent lamps. HERZOG, C. June 14, 1945, No. 15084. Convention date, March 7, 1944. [Class 39 (i)] A cold electrode fluorescent discharge lamp is manufactured by coating the envelope internally with a dried unbaked fluorescent compound leaving zones uncoated at each end, introducing electrodes supporting the tube in clamps which locate the electrodes and form a vacuum-tight joint at each end, circulating hot gas to bake the coating, evacuating the envelope and heating the envelope adjacent each electrode to cause it to collapse and form a vacuumtight seal, thereafter severing the open ends. As in Fig. 1, the tube 10 previously coated with a fluorescent material and dried is vertically supported in a holder 15, the electrodes each comprising a shell 16 and retainer 18 of chrome iron alloy having the same thermal coefficient of expansion as glass, being held in clamps 29 provided with external electrical connections. The electrodes may be of three other forms, the first with a closed end 17<1> and welded contact wire (Fig. 10), the second and third with wires or radial straps welded to the sides of the electrode shell and to the bottom of the retainer 18 respectively. Each end of the tube is held in a block 21 containing a compressible packing 24 which is compressed by a ring 25 and a water-cooled screw-threaded cap 33. A hot-air port 37 and a vacuum port 40 lead into the lower unit 20 each with cut-off valves. The upper unit 19 contains the hot-air discharge pipe and gas inlet tube with a rotary valve to determined which is to be in communication with the tube. A well 48 contains mercury and a tapered valve element admits into the tube a small measured quantity as desired. The mercury and gas, e.g. argon or neon, are admitted after the bottom end of the tube has been sealed by induction heating of the glass wall. The electrodes are connected to a source of current during the evacuation of the tube so as to heat the electrode shells and drive out undesirable gases and impurities. The sealing of the upper part of the tube is also carried out by induction heating and may be assisted by forming jaws.

Title: Improvements in or relating to Range Keeping or Predicting Instruments.
Inventor: FORD HANNIBAL CHOATE
IPC: G01C3/00
Filed: 1919-06-16
Abstract: 128,564. Ford, H. C. June 15, 1918, [Convention date]. Computing gun-sighting corrections.-Relates to apparatus for use in gunnery for range keeping and predicting, the rate of variation of the range being known. The range being set by means of a handle 30 and gearing as shown on indicators 1 and 2, the necessary addition to show the present range on the indicator 1 is continuously applied by a roller 5 driven from a timedriven disk 3 by a ball 7 the position of which is set by means of a handle 12, gearing, and a rack 19 carrying a cage 8 surrounding the ball. This variable speed mechanism is similar to that described in Specification 115,345, [Class 80 (ii), Gearing, Variable-speed &c.]. A dial 40 shows the rate of change of range set. The addition is also made to the indicator 2, through a differential gear 45 which allows a further correction to be added to give the predicted range at the moment of impact of the shell. This correction, equal to the time of flight multiplied by the rate of change of range, is obtained by means of an arc 52, set for the rate of change from the handle 12, and carrying a slot 53 in which works a pin on a block 55 sliding in a slot 56 and positioned therein by a screw 58, pinions 59, 60 and jointed shaft 61, 62 gearing with the range-setting spindle 24. The slot 56 is formed in a plate 57 swinging on links 70, 71 the latter carrying an arc gearing with a shaft 75 carrying the spider of the differential gear 45. The time of flight being approximately proportional to the range, corresponds to the radial setting of the pin in the slot 53 and is therefore multiplied by the rate of change of range set as a deflection of the plate 52 which is pivoted at 52' and thus the product, the correction in question, is applied through differential gear 45 so as to display on the indicator 2 the predicted range. While the range is being set on the indicator by means of the handle 30, the roller 5 is rocked out of gear with the ball by means of a key 30'. A differential gear 33 introduced on the spindle 62 permits a correction for the time of transmission to be applied by a handle 65.

Title: Process for the electrolytic precipitation of sodium
IPC: C25C1/02
Filed: 1960-04-29
Abstract: Sodium metal is made by electrolysis of a melt of compound MeAlR3R1 where, R is alkyl preferably of 2 to 6 C atoms, R1 is H, alkyl, alkoxy, or aroxy group.  Me is sodium or a mixture of sodium and potassium containing not more than 80% of K. The free metal alkyls formed are prevented from mixing with the sodium in the catholyte either by using a diaphragm or by operating in vacuo when the metal alkyls are distilled off. The electrodes may be inert, e.g. Ag, Au, Pd, Mn, Pt, Cu, Fe, Ni, Co, and the anode may be an inert or reactive metal or crude Na or Na amalgam. The metal alkyls, e.g. Al(R3)3 produced at the anode may be reconverted to the electrolyte by adding compounds of the type MeAlR3OR1. In examples the following electrolytes were used with a crude sodium anode, (1) sodium aluminium tetra-ethyl, and the potassium compound, and with lead or other anode reacting with the aluminium alkyl formed, (1) the sodium/potassium complex and sodium butoxy aluminium tri-ethyl, or Na/K aluminium tetrabutyl. In the latter cases the deposited sodium is caught and retained in a net, e.g. of fibre glass, suspended in the molten electrolyte layer, below which is a layer of crude sodium amalgam. Specifications 814,609, 848,364, 864,393 and 923,651 are referred to.
