Abstract: 598,609. Electric selective signalling. HAZELTINE CORPORATION. Aug. 25, 1945, No. 21884. Convention date, Sept. 15, 1944. [Class 40 (i)] [Also in Group XL] In a radio position-indicating system (see Group XL), the frequency-selecting switches of the receiving apparatus and also the positioning of appropriate maps over the screen of a cathode-ray tube indicator are controlled by an automatic selector system. The selector switch 54 completes the energizing circuit for the motor 57 via the selected contact 62 and the two-part commutator 61. The motor drives the roller 52 which positions the map 49 over the face of the cathode-ray tube and also drives via gearing 63, 65 the commutator 61 and the frequency - selector switches 46-48. When switch 54 is operated, the motor 57 rotates in the appropriate direction, determined by the initial position of the commutator, to rotate the selector switches to the desired position and position the appropriate map, the motor rotation ceasing when the insulating portion of the commutator reaches the selected contact 62.

Title: Improvements in methods of preparing fluorine derivatives of hydro-carbons
IPC: C07C17/20
Filed: 1933-08-05
Abstract: Fluorinated acyclic hydrocarbons or aryl derivatives thereof are made by reacting a hydrocarbon halogenated with another halogen, with hydrofluoric acid in presence of a halide of copper, silver, gold, sodium, zinc, cadmium, mercury, calcium, vanadium, manganese, iron, cobalt, nickel or platinum, which may be supported on a carrier such as active carbon or alundum.  The halides may be used single or together, mixtures mentioned including mercuric, manganese, sodium and cupric chlorides; manganese and silver chlorides; ferric, cupric and mercuric chlorides on alundum; ferric chloride on steel wool; and chlorides of any of the metals mentioned on active carbon.  The initial halogenated hydrocarbon may be made in situ by initially introducing a chlorinating agent such as antimony pentachloride. Those parts of the apparatus which come in contact with hydrogen halide may be made of copper, monel metal, mild steel, or chromium or molybdenum steels, and the scrubbers for removing hydrogen halide from the reaction product may be made of phenol-formaldehyde resin or lead.  The reaction is preferably effected in the vapour phase but at least one of the reactants may be liquid; for instance hydrofluoric acid is liquid at 80 DEG  C. under 5--6 atmospheres pressure.  Many halogenated hydrocarbons are mentioned as initial materials, including methylene chloride, fluorotrichloromethane, ethyl bromide, chloroform, bromoform, iodoform, benzotrichloride, benzofluorodichloride, and benzotrichloride derivatives ring substituted by alkyl groups or halogens; when the initial substance is unsaturated, addition may occur, for instance chlorethylenes may be treated with chlorine and hydrofluoric acid to yield fluorochlorethanes.  The hydrofluoric acid need not be dry.  In examples, hydrofluoric acid is reacted with (1), (2), and (4) carbon tetrachloride in presence of cuprous chloride in charcoal, ferric chloride on charcoal, and cuprous chloride on active carbon respectively; (3) difluorodichlormethane in presence of cuprous chloride on active carbon; (5) trifluorotrichlorethane in presence of vanadium tetrachloride on alundum, one of the products being pentafluorochlorethane which is said to be new; and (6) fluorotrichlormethane in presence of manganese chloride on alundum. A disclaimer relates to Specification 359,997.

Title: Improvements in oven heat control device
IPC: G05D23/185
Filed: 1921-08-22
Abstract: 188,105. Claus, E. L., and Claus, W. E. Aug. 22, 1921. Thermostats.-Relates to thermostats for controlling the temperature of ovens of the type comprising a member, such as a bimetallic strip, sensitive to temperature changes and adapted by a deflection in its medial zone to control the gas supply valve. According to the invention the supply of gas to the oven by the pipe 14, Fig. 3, is controlled by a valve 18 co-operating with a seating 16 and having a spindle 19 which is adjustably connected by nuts 48 threaded on the spindle to the centre of the bimetallic or like strip 38 adapted to bow when the temperature of the oven rises. The valve may be prevented from entirely contacting with its seating by an adjustable stop 50 and any gas leaking past the spindle 19 as it slides in a surrounding plug 17 is returned to a pilot pipe 10 by a conduit 25. The thermostatic strip is secured at one end to a lug 34, Fig. 2, inside the oven by means of a spindle 39 with a clamping-head 41 and at the other end engages a reduced portion 37 of a screw 36 by which the strip can be adjusted for different temperatures. Lost motion between the strip 38 and the reduced part 37 is prevented by a spring 49, Fig. 3, which presses the strip continuously against one edge of the reduced part 37. The spindle, 39 passing through the lug 34 is controlled by a spring 42 which, supposing the strip has been heated to a high temperature and is being adjusted by the screw 36 to a lower temperature with the valve 18 closed, yields and so prevents damage to the strip 38 by deformation. Mounted on the adjusting screw and capable of being clamped thereon by a screw 64, Fig. 4, is a nut 57 having an annular groove 63 in which engages a pin 62 attached to a pointer 56 pivoted at 61 to a dial 31.
