Title: Improved manufacture of photographic media
IPC: G03F7/038
Filed: 1926-02-04
Abstract: 270,387. Wade, H., (Wadsworth Watch Case Co.). Feb. 4, 1926. Plates and films; sensitive coatings, preparing, .-A light-sensitive varnish, of the kind described in Specification 203,285, and which may be kept without deterioration for long periods, is produced by preparing a solution of hydrophobic colloids containing, almost to saturation, metallic salts which will combine with free halogen, and by introducing into this solution a free halogen only in sufficient quantity to combine with sub sta.ntially all the metallic salts without leaving a residue of free halogen. In addition to the metal. lic halide so formed there may be included an organic sensitizer such as iodoform which liberates a halogen on exposure to light. Colloids which may be used include natural or synthetic resins, such as asphaltum, guttapercha, kauri resin, coumarone resin, or shellac; cellulose ace. tate or nitrate; or light sensitive oils such as tung oil. As metallic salts, resinates or tungates of lead, manganese, aluminium, zinc, or cobalt may be used. An example is described wherein a varnish comprising mainly tung oil (chinawood oil) and also coumarone resin and lead resinate is first cooked and then dissolved in a mixture of benzine and benzol. To this are added in succession solutions of (a) iodoform in benzol, (b) guttapercha in carbon tetrachloride and benzol, and (c) iodine in benzol, the amount of iodine being sufficient to combine with substantially all the lead without leaving a residue of iodine which would render the varnish unstable. Tung oil may be replaced by perilla oil, soy bean oil, lard oil, cotton seed oil. fish oil, castor oil, linseed oil, menhaden oil, or kerosine, or by a mixture of oils. On exposure to light passing through a negative &c., a coating of the varnish is hardened at the parts exposed, and may be developed as by dipping into a solution of turkey red oil in carbon tetrachloride and washing in benzine. The hardened parts may be coloured or stained.

Title: Automatic control of the temperature of a heating device
IPC: G05D23/22
Filed: 1955-02-04
Abstract: 782,285. Automatic temperature contro) systems ; automatic voltage regulation. PHILIPS ELECTRICAL INDUSTRIES,. Ltd. Feb. 4, 1955 [Feb. 9, 1954], No. 3402/55. Class 38 (4). In a temperature control system for an induction furnace supplied through an H.F. generator 1 from the A.C. mains, a heating winding 2 is energized in series with an inductance 3, the latter having its core 4 movable by a reversible motor 19 for. varying the heating current to maintain a desired furnace temperature. The output of a temperature-detecting thermocouple 29 is applied, over a filter 5 and a self-compensating circuit (not shown); to move a temperature indicator 7 and its associated contact 8 on a potentiometer 9, the latter having a datum-setting contact 10. A proportion of the temperature-deviation voltage between contacts 8, 10 is tapped from a resistor 11, and applied with a compensating voltage from a core-driven potentiometer 16 to energize the core-positioning motor 19 over a converter 17 and an amplifier 18. The displacement of the core, and hence the change in heating current, is thus proportional to the original temperature deviation. The motor 19 is also controlled by a voltage from a potentiometer 26 representing the deviation of mains voltage from the normal value, a signal indicative of mains voltage being derived from a rectifier and smoothing network 24, 25 for comparison with a standard source 27. This voltage is also compensated by that from potentiometer 16 so that the core is displaced in proportion to the mains voltage fluctuations with a time lag substantially less than that due to furnace temperature variations. The motor 19 is connected in a closed feedback loop with a generator 20 and amplifier 18, the movements of core 4 being thereby damped. Adjustable tappings 12, 13, 28 allow variations in the range of the proportional control of the core. The second control voltage may alternatively be derived from the output of H.F. generator 1, from a voltage operative within the generator or from the temperature of a medium heated by energy derived directly from the mains.

Abstract: 113,839. Insull, M. J. March 8, 1917. Resistance furnaces for reducing metallic oxides, e.g. tungsten trioxide, to metals. A nickel lining 20 extending only over a part of the length of the furnace protects both the silica or other refractory wall of the furnace, shown as a tube 6, and a surrounding nichrome heater 18, from injurious low oxides of tungsten, &c. The lining may be a thin 'sheet retained by its own elasticity. Around the silica tube 6, except at its ends, is a packing of magnesia in a metal casing 7. Pyrometers 29 are provided at various points along the tube. Watercooled heads 11 are secured to the ends of the silica tube by a mixture of plaster of paris and gum arabic. Where exposed to the air, the composition may be painted with " bakelite," to exclude moisture. Hydrogen, preferably under pressure, is admitted through a pipe 27, and after being heated to the reduction temperature, for instance by a nichrome strip 15, passes rapidly, say at 8-12 feet per second, over the oxide. In preparing the preheating strip for insertion, it is wound on a flat bar, and on removal therefrom uncoils slightly so as to stagger the convolutions as shown. Its inner end is held by an axial nickel rod 14 insulated by a silica tube. A baffle 28 opposite the inlet 27 ensures distribution of the hydrogen over the heating-strip. A nickel boat 21 of nearly cylindrical form has two horizontal partitions so as to carry three layers of oxide, and may be permanently attached to a wire for withdrawal from the plugged outlet end of the furnace.
