Title: Improvements relating to the production of branched chain alkanes
IPC: C07C5/27
Filed: 1941-07-01
Abstract: 556,895. Isomerising hydrocarbons. ANGLO-IRANIAN OIL CO., Ltd., FAWCETT, E. W. M., and JENKINS, G. I. July 1, 1941 No. 8306. Drawings to Specification. [Class 2 (iii)] Branched chain alkanes are produced by subjecting normal alkanes containing more than three carbon atoms in the molecule to the reaction temperature while carrying in suspension the vapour of a metallic halide catalyst such as an aluminium halide having a measurable vapour pressure at or below the reaction temperature, the mixture of catalyst vapour and product, after leaving the reaction vessel, being passed through a sorption vessel packed with a sorptive medium until this medium becomes saturated or partly so with catalyst. The sorption vessel is then used as saturator to supply catalyst to the normal alkane which is passed therethrough. Examples are given of the isomerization of n - butane using bauxite as sorptive medium. Small losses of catalyst are made up by passing the alkane over lump aluminium chloride. Specification 556,894 is referred to.

Title: Improvements in viscosity responsive means
IPC: G01N11/08
Filed: 1944-05-03
Abstract: 576,257. Lubricating systems. BOOTH, H. T. May 3, 1944, No. 8353. Convention date, Oct. 18. 1943. [Class 12 (iii)] [Also in Groups XIX and XXXVII] In a viscosity responsive instrument suitable for use in controlling the supply of a diluent fluid to a lubricating oil or other viscous fluid supply system, as described in Specification 576,256, the viscous fluid passes through a friction tube, a pressure chamber, and an orifice regulated to compensate for variation in viscosity due to varying temperature, and the fluid pressure in the pressure chamber regulates the supply of diluent fluid to mix with the viscous fluid. The body 43 of the instrument shown is formed with three longitudinal bores 44, 45, 46 closed at one end by a cap 47. Oil or other viscous liquid pumped through a gland 51 into the bore 44 passes through a screen 52 to a port 53 communicating with an annular groove in the bore 45 surrounding a ported bushing 50 in which a skirted piston 57 formed with ports 58 is slidable against the resistance of a spring 59. The piston 57 surrounds a friction-tube 63 through which the oil passes with a rate of flow dependent on its viscosity to a chamber 45b from which it escapes through an orifice 67 in a flow restricting disc 66 to a chamber 46b having an outlet 56. A constant pressure differential is maintained between the two chambers 45a, 45b on opposite sides of the piston 57 by the movement of the piston relatively to the ports 60 in the bushing 50. An increased pressure in the chambers 45a. 45b due to diminished viscosity is communicated through a groove 68 in the cap 47 to the bore 46 and operates a piston 69 against the resistance of a spring 71 and the pressure in the chamber 46b to open a switch 36 in the circuit of a solenoidoperated valve controlling the supply of a diluent to the oil. To eliminate the effect of changes of viscosity due to the temperature of the oil the area of the orifice 67 is regulated by a needle valve 79 operated by a thermal element 83 in the chamber 46b. The piston 69 operates the switch 36 by means of a rod 74 having an offset end pivotably connected to a similarly offset end of a rod 75 passing through and soldered to a flexible metal diaphragm 77 forming part of the closure 49 of the chamber 46b. A pin 80 passing through the rod 75 and abutting the rim of the closure 49 prevents movement of the diaphragm and rod due to pressure in the chamber 46b.

Abstract: 595,210. Thermionic valve circuits for amplifying. 'PHILCO RADIO & TELEVISION CORPORATION. April 6, 1945, No. 8576. Convention date, Nov. 20, 1944. [Class 40 (v)] An amplifier operating over an extended frequency range comprises two valves connected by a coupling condenser in shunt with two resistors having a constant potential device between them, the resistors having impedances high compared with that of the device at low frequencies and low compared with that of the coupling condenser. As shown, the anode of valve 10 is coupled to the grid of valve 26 through coupling condenser 23, which has a low impedance at the higher frequencies, the resistors 40 and 41 being high enough to isolate the gas discharge tube 42 so that its distributed capacity to ground does not effect the upper cut-off frequency. The resistors are made physically quite small so that they have negligible distributed capacity. At the lower frequencies, including direct current, the impedance of condenser 23 is high compared with that of resistors 40, 41, causing tube 42 to strike, thus providing a path for the lowfrequency signals. A peaking inductance 18 may be provided in the output circuit of the first valve for maintaining the output voltage at the higher frequencies.
