Title: Process for the production of alkyl halides
IPC: C07C17/16
Filed: 1946-01-23
Abstract: Alkyl halides are obtained from the corresponding mono- or polyhydric alcohols which are still liquid at the reaction temperature by bringing a gaseous halogen hydracid into contact, in counter-current, with the liquid alcohol in a reaction column, the temperature of the reaction being adjusted so that the alkyl halide, either completely or partly separated from the water formed, is distilled off continuously at one end of the reaction column, and the water formed, or the remainder of the water formed, is continuously removed at the other end of the column, or so that the alkyl halide, either completely or partly separated from the water formed, is continuously removed from one end of the column, and the water formed, or the remainder of the water formed, is distilled off continuously at the other end of the column.  In examples: (1) lauryl alcohol heated to 120 DEG  C. is run on to inert filling material in a long tubular vessel and gaseous hydrobromic acid introduced by the bottom inlet, the temperature in the centre of the tube is about 130 DEG  C. and the lauryl bromide produced is continuously removed from the bottom outlet while the water of reaction distils off at the top; (2) isopropyl alcohol and gaseous hydrochloric acid are reacted as in (1), the temperature in the centre of the reaction vessel being 80 DEG  C. and a reflux condenser being arranged at the top of the vessel so that part of the isopropyl chloride which distils off at the top is returned to the reaction vessel while the water of reaction is removed at the bottom.

Title: Hydraulic pressure system
IPC: F16D65/22
Filed: 1945-02-02
Abstract: 591,873. Brakes. PAGE, H. E. Feb. 2, 1945, No. 2670. Convention date, Jan. 31, 1944. [Class 103 (i)] A high and low pressure hydraulic master cylinder, controlled by a pedal-operated rod 12 connected to a piston 10, accommodates a piston 8 having a reduced tubular part 8a which projects into the reservoir R and provides a cylinder bore 9 for the piston 10. The head of the piston 8 has a passage 40 closed by a spring-loaded valve 41 leading to a passage communicating with the annular chamber 15. When the pedal is depressed, the liquid trapped in the bore 9 moves the piston 8 in unison with the piston 10 whilst the slack in the brakes is being taken up and the pressure in the chamber 24 remains low in consequence. During this movement make-up fluid is drawn from the reservoir through the port 27 and valve 32 into the chamber 15. When the brake shoes contact with the drum, the pressure in the chamber 24 rises, and the corresponding rise in the bore 9 lifts the valve 41 and the pressure of the piston 10 is applied to the chamber 15. Release of the pedal permits the spring 14 to pull out the piston 10, and the spring 22 to move the piston 8 in the same direction. Liquid in the space 15 returns to the bore 9 past a spring-loaded valve 36 and passage 34, and to the reservoir past the same valve and a passage 50. Loss in the chamber 24 and in the brake cylinder is made up through a passage 25, valve 29 and passage 26. The master cylinder may be connected with the brake cylinder described in Specification 587,099.

Each part of the magnetic structure is provided with a winding L located on the vertical limb between the two inner polepieces and a second winding T embracing the two inner pole-pieces. Each winding is connected in series with the companion winding on the other magnetic part. For controlling the signals on an insulated section 10 of railway track, the windings L are connected to an alternating-current generator G, the track is connected to the generator through a transformer 13 the secondary of which contains a reactance 14 which produces a displacement of phase of the current taken from the track by the windings T in relation to the current in the windings L. The signal S is held at " clear " when no train is on the section by the action of the two magnetic fluxes relatively displaced in phase, which raise the vane and close a local signal-operating circuit at K. When a train is on the section the cons Tare short-circuited, the vane falls and the local circuit is broken, and the signal moves to " danger."
