Title: Process for the manufacture of electric lamp bases from hard glass or quartz glass and incandescent lamps incorporating bases made by such process
IPC: H01K3/20
Filed: 1938-06-25
Abstract: 504,874. Sealing leading - in conductors. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.-GES. June 25, 1938, No. 18919. Convention date, June 25, 1937. Drawings to Specification. [Class 36] Lamp bases are manufactured by sealing leading-in conductors, in the form of wires or foils of refractory metal, into a hard glass or quartz glass capillary with two ducts by a glass-fusing operation which, in itself, establishes complete hermeticity. Tungsten wires may be sealed in directly ; or, molybdenum foils connected to tungsten or molybdenum wires may be introduced into the capillary which is then sealed off at one end, evacuated, and heated at the sealing points with an oxyhydrogen flame, the projecting ends of the capillary being then cut off. The capillary may be formed by sealing a rod into a flattened tube of the same glass, or by simultaneously flattening a tube and sealing therein a previously introduced rod.

Title: Improved manufacture of photographic anti-halation coatings
IPC: F16G13/14
Filed: 1928-06-29
Abstract: 294,104. I. G. Farbenindustrie Akt.- Ges. July 16, 1927, [Convention date]. Halation, preventing. - Anti-halation supports for sensitive layers, particularly panchromatic emulsions, are produced by incorporating uni. formly in one or several layers of the support two or more organic or inorganic dyestuffs selected so that (1) a spectral absorption gap of one corresponds with a maximum spectral absorption of one or more of the others, and (2) they are either wholly bleached in the developing &c. baths for the sensitive layer, or, if colour is desired in the finished image, are only partially bleached in these baths. Examples of dyestuff combinations according to the invention are (1) malachite green and acid magenta (2) manganese dioxide and washing blue, and (3) Bismark brown and methyl blue, or aniline blue and acid magenta, which only partially bleach in the developing &c. baths, especially when the chemical reversal process is followed. The colloid carrier of the dyestuffs may be gelatin, cellulose derivatives, or resins. The Specification as open to inspection under Sect. 91 (3) (a) states also that for panchromatic layers, the dyestuffs should have no absorption gaps corresponding with the absorption gaps of the filters to be used with the layers. This subject-matter does not appear in the Specification as accepted.

Abstract: 357,628. Jigging conveyers. RIDGILL, E., Dronfield, Sheffield, Derbyshire. June 24, 1930, No. 19278. [Class 78 (i).] Mechanism for imparting reciprocating motion to the trough of a jigging conveyer in such a manner as to produce a relatively much more rapid reversal of motion to the trough at the end of each forward stroke than at the end of each return stroke, is so designed that after the rapid reversal of motion at the end of the forward stroke, the return movement of the trough conforms substantially to simple rectilinear movement derived from uniform rotational movement. A crank shaft 5 rotated at a uniform speed is connected by a rod 9 to a pin 10 carried by one arm 11 cf a bifurcated doublearmed lever 11, 12. A pin 15 mounted in the arm 12 is connected by a rod 16 to pin 17 mounted on a block 18 which is slidable in guides 19. A pin 20 mounted on the block 18 is connected by a link 21 to a crank pin 22 provided on a crank shaft 23. A pair of bifurcated arms 26, 27 keyed to the shaft 23 are provided with holes 28, 29 arranged in radial alignment. A pin 30 placed in either of these holes connects a link 31 to each arm. The other end of each link has a rectangular aperture through which is passed a bar 32. One end of this bar is connected by a rod 35 to a pin 36 secured to the side of the conveyer trough. In a modification the arm 27, Fig. 4, is connected by a link 31 to a swivel connection comprising articulated members 38, 39. The member 39 is pivotally connected to a double-armed lever 42, 43 which is pivotally mounted on a pin 44. Pins 46, Fig. 6, depending from a shoulder 45 on the pin 44 engage holes in the baseplate 3. The arm 43 is connected by a link 51 and a connecting-rod 53 to the underside of the trough. If desired the link 31 may be connected to the arm 26 and the pin 44 secured to the opposite side of the base. Specification 351,348 is referred to.

Abstract: 319,429. Scott, W. H.. Scott, G. J., and Wheeler, H. D. July 4, 1928. Controlling motors by varying terminal voltage; varying field.-In order that a D.C. motor 3 which drives a winch or hoist may automatically vary its speed in inverse proportion to the load, its armature is connected across a generator 2 in series with a motor 1 across the mains, and series field-windings, for the respective machines 1, 2 are so arranged that the series field 13 opposes the shunt field 7 of the machine 2, while the series field 12 assists the shunt field 6 of the machine 1. The effect may be enhanced by providing the working-motor with a field-winding 14 connecte@ across the machine 1. Preferably the effect takes place only during the full-on position of the motor-controller (not shown); the counter field 13 being short-circuited in other positions of the controller by a switch 15. The machines 1, 2 constitute a motor-generator combination, the relative field-strengths of which are varied as required by a potentiometer controller 9. The arrangement includes a reversing switch 16 for setting up regenerative braking, magnetic brake windings 17, 18 as described in Specification 232,063, [Class 103 (i), Brakes &c.], and a load discriminator as described in Specification 113,993.

Abstract: 256,965. I. G. Farbenindustrie Akt.- Ges. Aug. 14, 1925, [Convention date]. Grant of Patent opposed. Hydrogenation, destructive. - In the production of lighter liquid hydrocarbons by treating coals, tars, mineral oils, and like carbonaceous bodies at elevated temperatures and pressures of at least 50 atmospheres with hydrogen or gases containing or giving rise to hydrogen, the materials are treated in a gaseous or a finely divided liquid or solid state. Catalysts, e.g. tungsten or nitrogen, may be added to the gas or carbonaceous material, or may be arranged in a contact room so that the reaction gases pass over them. The hydrogen may be circuited for reuse after addition of water vapour, fresh hydrogen, or both. Carbonaceous material insufficiently converted may be circuited for further treatment, slag and residue being removed en route without loss of pressure; or it may be passed through a series of reaction vessels. The carbonaceous material is obtained as the desired gas, vapour, mist, or dust in the reaction chamber by mechanical means and with the aid of hydrogen, or by injection through nozzles, either alone or with inert gases or heavy benzines or other readily vaporized substances, into a reaction chamber filled with hydrogen, local superheating of the vaporizing or distributing devices being adopted, if desired, or by any combination of these means. In an example, a mixture of 2 tons of mineral oil and 1 ton of lignite containing 40 per cent of water is introduced as a fine mist and at 200 atmospheres pressure into a reaction vessel, and acted upon at 450‹ C. with a mixture of hydrogen and nitrogen. No coking occurs. Specification 255,127, [Class 1 (i), Chemical processes &c.], is referred to.
