Patent GB-570962-A (GB)
Title: Improvements in the manufacture of metal hypochlorites
IPC: C01B11/06
Filed: 1943-07-20
Abstract: In the production of alkali or alkaline earth metal, e.g calcium hypochlorites, by reacting the corresponding metal oxide, hydroxide or basic hypochlorite with an alkyl hypochlorite, the alkyl hypochlorite is employed in the vapour phase.  Tertiary alkyl hypochlorites, such as tertiary butyl- or tertiary amyl-hypochlorite are preferably employed.  The alkyl hypochlorite may be vaporized under reduced pressure and/or by passing a stream of air or nitrogen through the liquid.  The reaction is facilitated by the preseure of water which may be supplied to the reaction zone in the vapour-phase or may be present in the metal oxide or hydroxide.  The process may be conducted by continuously feeding the solid downwardly through a reactor in counter-current to a stream of vapour.  The process may be employed in carrying out the third step of a cyclic process in which (1) an alcohol is reacted with aqueous hypochlorous acid, or with chlorine and sodium or calcium hydroxide in the presence of water to produce an alkyl hypochlorite; (2) the alkyl hypochlorite is separated from the aqueous phase; (3) the separated alkyl hypochlorite is reacted with the metal oxide or hydroxide to form the corresponding metal hypochlorite and alcohol, which latter is returned to the first step of the process, as described in U.S.A. Specifications 1,632,483 and 1,632,485.

Title: Gas turbine engine
Inventor: COPLIN JOHN FREDERICK
IPC: B60Q1/26
Filed: 1969-03-06
Abstract: 1,210,202. Gas turbine engines. ROLLSROYCE Ltd. March 6, 1969, No.11977/69. Heading F1G. The invention relates to a gas turbine engine in which means are provided for supplying heated air to a member at the inlet end of the engine to effect anti-icing thereof, the air then passing into the intake of the engine. Vortex means are provided to produce vortex flow in the air stream to ensure mixing thereof with ambient air passing into the intake thereby cooling the air stream before it enters the compressor of the engine. A fairing member or bullet 21 is secured to the compressor rotor 20 by means of an annular wall member 22 and a deflector 24 is secured to the member 21 so as to define a passage therebetween through which air heated by compression in the compressor and supplied through duct 23 is passed, the heated air serving to effect anti-icing of the fairing member. A series of vortex-producing members in the form of bosses 25 are mounted at the downstream end 26 of the member 21 and cause eddying of the anti-icing air stream and so mixing of the air stream with the air flowing into the intake of the compressor so that the anti-icing air is cooled before it flows into the compressor. Some of the cooled air may pass through openings 27 and 30 into the interior of the compressor rotor so as to prevent the compressor being heated by the heated air flow. The compressor blades 17 may be made of synthetic resin material which might be damaged by the anti-icing air if it were directed on to them without first being cooled.

Title: Improvements in or relating to the hydration of olefines
IPC: C07C29/04
Filed: 1931-12-22
Abstract: The hydration of olefines for the production of alcohols and ethers is effected by leading the olefine mixed with steam through a phosphoric acid which is initially anhydrous or substantially anhydrous.  The temperature may be 100-350 DEG  C. or more and the pressure up to 25 atmospheres or more.  The olefine and steam may be passed through a molten bath comprising the phosphoric acid, and the bath may contain other substances which may or may not have a catalytic effect.  The gases may be preheated.  For making diethyl ether the proportions may be two or more volumes of ethylene to one volume of steam, while for alcohol equal volumes of ethylene and steam may be used.  The production of isopropyl alcohol from propylene and steam is mentioned.  Mixed olefines may be used to produce mixtures of alcohols.

Abstract: 926,973. Automatic exchange systems. SIEMENS & HALSKE A.G. April 4, 1961 [April 4, 1960], No. 12078/61. Class 40 (4). In a system in which some stations are equipped for the transmission of data as well as speech, separate meters are allocated to the two types of transmission and discrimination is effected by a circuit UE forming part of the line circuit TS. A telephone call from the set FR is established in the normal manner, the meter Z1 being operated by impulses over a fourth wire. A call for the transmission of data from a device D is initiated by the actuation of a key TE or of a preadjusted clock contact zt2. Switching relay U1 closes the loop and selecting impulses are sent from a device N to establish the required connection, these impulses being preceded by an A.C. signal which operates relay U2. The selecting impulses also set a switch dm which connects up relay F, in the case of a trunk call. Relay U2 locks under the control of cut-off relay T and connects up the meter Z2 or Z3 according to the condition of relay F. The meters record different charge units. Data transmission may be prevented at certain times by a blocking relay S2 which is dependent on a clock contact zt1, relay U and, if desired, relay F, or relay S2 may control a further meter change-over. The metering impulses may be sent in high-frequency form to a receiver G at the subscriber's station to control different meters. On an incoming call the switch-over by relay U1 for data transmission may be effected by high-frequency ringing current which does not operate the bell. Specification 926,972 is referred to.

Abstract: 781,294. Bottle washing machines. HALL, J., and HALL, C. July 27, 1955 [April 27, 1954], No. 12091/54. Class 138(1). A container washing machine, Figs. 2 and 3, includes a reservoir 10a, a guideway 15a extending over the reservoir, a series of upwardly proj ecting nozzles 19 fixedly mounted beneath the guideway 15a and means for drawing liquid from the reservoir 10a and feeding it under pressure to the nozzles to enable containers supported on the guideway in a holder such as a crate to be subjected to jets of liquid, the guideway being in the form of a frame 15 pivotable about an axis forward of the nozzles 19, whereby with the frame 15 raised, a holder with inverted containers may be positioned above the nozzles and the frame subsequently lowered to bring the container necks over the nozzles, which latter enter the necks. The guide frame 15 comprised of side angle members 15a and a rear angle member 15b, is pivoted at its front end by a spindle 16 to angle members 14 bolted to the top flange of a tank 10 which is divided by a partition (not shown) into two compartment reservoirs of which only 10a is shown. A handle 28 rotatable on a pivot 29 is connected by links 30, 31 to a shaft 32, in turn connected by links 33, 34, Fig. 3, to a rod 35 on the rear frame member 15b. Upward movement of the handle from the position shown in Fig. 3, causes the rear end of the frame 15 to lower relative to the members 14 so that bottles 39, Fig. 2, retained in apertures a holder plate 38, provided with runners 40 to slidably engage the angles 15a, are lowered over the nozzles 19 which are carried by a hollow casting 18 bolted at 18a to the members 14. Liquid in the reservoir 10a is heated (preferably by electric elements) and withdrawn therefrom by a pump (not shown) which supplies the liquid to a pipe 22 past a valve to a pipe 23. The pipe 23 is connected to the casting 18 and also to a pipe 24 connected to a horizontal rotatable nozzle pipe 25. In the position shown the pipe 25 is supplied with liquid but if rotated through 90 degrees by a plate 27 secured thereon the supply of liquid is cut-off. The supply valve in the pipe 22 is operable by the handle 28. On moving the handle 28 to the position shown in Fig. 3, the bottles are raised from the nozzles 19 and the holder 38, 40, may be slid to the front of the frame 15 and over a plate member 17 pivoted on the spindle 16. A similar washing unit to that shown in Fig. 2 is provided over the other compartment of the tank 10. The latter compartment contains water together with bactericide and detergent for washing purposes whereas the compartment 10a contains water with bactericide only, for rinsing purposes. Each compartment is partly covered by a canopy 26.
