Title: Improvements in and relating to small electric arc lamps
IPC: H05B31/00
Filed: 1924-10-17
Abstract: 244,862. Angus, T. C. Oct. 17, 1924. Arc lamps.-In non- automatic electric arc lamps, the arc is started and the carbons or other electrodes are set at a predetermined distance apart, and fed and reset as they burn away, by a double movement, pull and release, of a Bowden wire or other distant hand or foot control. The holder for the upper electrode is mounted on a slide S guided for limited vertical movement by rods, or by studs and slots, on a carriage C'. A spring W acts between a lug L on the slide S passing through a slot in the carriage C<1> and a lug F on the carriage C' and so maintains the slide S in raised position. The carriage C' slides on rods V on a stand or bracket carrying the lower electrode and is locked in position by a double catch C and a, spring g stronger than the spring W. The casing of the Bowden control acts against the upper side of the lug L and the central wire passes through the lugs L. F and the springs W, g and is attached to the joint of the catch C. An initial movement of the control compresses the spring W and lowers the slide S on the carriage C', further movement of the control then compresses the spring g, releases the catch C, and allows the carriage C<1> to drop by gravity until the electrodes touch, release of the control allowing the spring g to operate the catch C to lock the carriage C<1> in its new position and then allowing the spring W to expand to raise the slide S and the upper electrode through a distance determined by the setting of the screw A and indicated on a scale X. Each half of the catch C may be controlled by a separate spring. A refractory disc D is arranged above the upper electrode and a fireproof tray beneath the electrodes. A nickel or other reflector of ultra-violet light is provided when the lamp is used for therapeutic purposes. The movement of the carriage C<1> may be braked by springs or other friction devices. Specifications 104.907, 131,030 and 160,571 are referred to.

Abstract: 954,919. Retractive switches. NATIONAL REJECTORS Inc. July 10, 1961, No. 24940/61. Heading H2B. A small snap-action switch comprises a two-part casing 20, 22 which secures copper terminal lugs 84, 94 and 104 in position as shown. The lugs 84 and 94 carry fixed contacts 90 and 100 respectively and the lug 104 has a leaf-spring 112 riveted thereto so as normally to urge a moving contact 116 on its free end into engagement with contact 100. A permanent magnet 120 is a tight fit in a yieldable plastic sleeve 118 fitted in an aperture in leaf-spring 112 and co-operates with armatures 122, 124, carried in the easing. These armatures may be the arms of a U-shaped member (Fig. 11, not shown). The casing also journals an actuating shaft 126 having an eccentric crank-like portion 130 adjacent the spring 112 such that rotation of the shaft 126 causes the part 130 firstly to cam the spring 112 into the shape shown in Fig. 9, wherein it pivots about magnet 120 and polepiece 122 to increase the contact pressure, and then to snap into the position shown dotted, wherein contact 116 engages the other fixed contact 90. On release of shaft 126 the spring 112 re-asserts its full-line position with a similar pivoting action of magnet 120 on armature 124, followed by a snap-over. This action also produces a wiping and cleaning movement between the contacts. The shaft 126 is operated by an arm 154 resiliently maintained between abutments 148, 150 and 152 on a coupling member 140 attached to shaft 126. The member 140 also has a projection 144 co-operating with stops 52 and 54 formed on the casing 22. The casing has holes 26, 28 for mounting purposes, and the two parts 20 and 22 are held together by a split tube 162 compressed inside a hole 30 therethrough. In a modification (Fig. 10, not shown), the cam-shaft assembly is replaced by a pushbutton acting directly on the leaf spring.

Filed: 1944-12-14
Abstract: 587,642. Automatic control systems. ELECTRO METHODS, Ltd., and MAINZER, G. Dec. 14, 1944, No. 25100. [Class 38 (iv)] [Also in Group XIX] Fluid pressure.-In a device for maintaining a predetermined substantially constant fluid pressure in an enclosure, a liquid column pressure gauge is used in combination with a relief valve. The pressure maintained may be above or below atmospheric pressure. As shown, mercury rising in a manometer 2, as the vacuum in a vessel 1 increases, completes the circuit of a solenoid coil 20 to cause the relief valve 23 to be lifted to allow air to enter the vessel. The larger limb of the manometer has a branch 5 communicating with the vessel 1 and a capillary tube 24, the opening of the latter to atmosphere being closed by the valve 23. A screw 10 supported in the space 7 of the manometer is provided with a nut 11 carrying a wire 14 which can be adjusted relatively to the meniscus 6 of the mercury by rotating a magnet 13, disposed above the manometer, which causes 'rotation of the magnetic head 12 of the screw 10. A pointer 22 on the nut co-operates with a scale 21 on the manometer to facilitate setting the wire 14. The wire 14 and mercury column are connected to a source of electric supply by a lead 16, which is in series with the coil 20, sealed in the manometer to contact the head 12, and a lead 3 sealed in the manometer to contact the mercury, respectively. In a modification, a branch from the pipe connecting the pump to the vessel has two arms, each arm terminating in a capillary nozzle, one nozzle being closed by a spring-pressed plunger adapted to be opened by a .relay. One lead from the relay is connected to the mercury in a manometer which is a tube of inverted U-form, and so mounted that initial setting of the gap between the wire contact sealed in the upper end of the tube and the meniscus of the mercury canbe accomplished by tilting or rotating the tube.

Title: Improvements relating to the production of aqueous dispersions of chlorosulphonated polyethylene salts
IPC: C08F8/34
Filed: 1962-06-29
Abstract: An aqueous dispersion of a chlorosulphonated polyethylene is prepared by dissolving in a water-miscible organic solvent more volatile than water a lithium, sodium, potassium, ammonium and/or substituted ammonium salt of a chlorosulphonated polyethylene containing 0.5-1.8% sulphur and 10-48% chlorine, adding in one or more increments water and as precipitant methanol, ethanol, isopropanol or acetone in an amount which renders the solution opalescent but which is less than is required to form a precipitate, and distilling off the solvent and precipitant.  The organic solvent may be tetrahydrofuran. The cationic component of the salt may be alkyl ammonium or hydroxyalkyl ammonium, or a primary, secondary, tertiary or quaternary substituted ammonium. A pigment, e.g. TiO2, may be added to the aqueous dispersion. Sufficient precipitant may be added to give in the aqueous dispersion solid particles 0.001-4.0 microns in diameter. When a Na, K or Li salt is used there may first be added to the salt solution 6-60% water and then in subsequent increments water and precipitant in increasing ratios of water to precipitant, e.g. 0.2-2.1 until a milky suspension is formed. Precipitant may be present in the salt solution in an amount less than that required to form a precipitate prior to the water addition.  The dispersions may contain dispersing agents, e.g. polyoxyethylene sorbitan mono-laurate and -oleate, dodecyl phenylpolyglycol ether, sodium salt of the acid sulphuric acid ester of 2-methyl-7-ethylundecanol-4, carboxylic acid esters, alkyl aryl polyether alcohols, sulphonated alcohols, salts of fatty acids, salts of polynuclear carboxylic and sulphonic acids. The dispersions may be used for coating, impregnating and film-forming. In an example a paint is prepared by diluting the dispersion with water and dispersing TiO2, a fibrous hydrated magnesium silicate, and mica in the dispersion which contains ammonia solution, sodium polyacrylate, polyethyleneoxide octylphenyl ether, potassium tripolyphosphate, and methyl cellulose.  Specifications 789,005 and 940,197 are referred to.
