A water-injection valve 8, Fig. 2, in each cylinder head 7 of a supercharged engine is opened during the compression stroke against a preferably adjustably-loaded spring 9 by the pressure of the water which is supplied from a reservoir 1, Fig. 1, via an engine-driven valve 3 distributing in turn to pipes 5 each serving a cylinder, by a pump 2 preferably bridged by a by-pass valve 13 which is controlled by a spring 14 adjustably loaded by a cam or screwed cap 15 operated by hand or automatically in dependence on engine load, speed or temperature. In a diesel, the quantity of water injected may be about 15 or 0À5 per cent by weight of the fuel oil or air, respectively, used. Preferably, the admission temperature of the water is as close as possible to the temperature at which water boils in the cylinder at that time. According to the Provisional Specification, the quantity and timing of water injection is preferably such that the water is fully vaporized at the end of compression and that the charge temperature then is equal to or lower than the final exhaust temperature.

Filed: 1919-11-20
Abstract: 142,047. Walker, W. Nov. 20, 1919. Transmitting-mechanism; fluid relays.-Speedcontrolling means for steam, gas &c. engines comprises transmission-mechanism, including a cylinder and piston, one of which is connected to the throttle-valve, means for admitting actuating fluid to the cylinder and a connexion between the governor and the said fluid-admitting means. In the arrangement shown, a shaft-governor 1 through a lever 4 actuates a shaft 5 to which is keyed a balanced lever 6, adjustably connected to a screwed rod 10 coupled by a spring-safetydevice 12 to a rod 13. This rod 13 is jointed to a lever 16 attached by a link to the fluid-admission valve 26, and to a piston 23 in a cylinder 25, Fig. 3. The piston is coupled by a link to a lever 20 which actuates the throttle valve 22. When the engine is started, the valve 26 is in the position shown, and fluid under pressure is admitted by the port 28 and passage 24 to the upper face of the piston which is forced down to open the throttle-valve wide. As the piston moves, it moves the valve and shuts off the fluid supply. Should the engine run too fast, the valve is depressed further by the governor and the fluid allowed to escape through the port 29, as the spring moves the piston upwards to close the throttle-valve.

Title: Automatic telecommunication exchange
IPC: H04Q3/00
Filed: 1967-06-23
Abstract: 1,128,427. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 23 June, 1967 [28 June, 1966], No. 29106/67. Heading H4K. In an exchange system having a reed-relay switching network through which paths are selected by means of a route simulation network, the latter's guide wires are busied by means of a distinctive potential when the corresponding links in the switching network are busy and in addition the guide wires are used for signalling, e.g. metering and identifying by utilizing pulses of different polarity from those used during route finding. The simulation network forms part of the switching network in that the guide wires run parallel with the interstage links and are switched by means of contacts, e.g. kx, ky, actuated by the crosspoint switches. The inlets and outlets of a same switching matrix are connected by individual diode gates Da, De to the matrix's "offering" signal regenerator AVA or AVB. In operation, contact ab in a free junctor VS is closed and offering potential +U is extended through the simulation network to all calling line circuits TS. One of the latter is selected whereafter the usual stage-by-stage selection of free matrices is made using a catching potential (not shown). When a unique path between TS and VS is set-up, the closure of contacts kx and ky effectively blocks the associated gates Da, De and a contact c in VS is closed whereby busy earth is extended over the guide wires of the just selected path to a busy relay B in the line circuit. During the call, metering pulses are applied to this path's guide wires by closing contact z in VS whereby potential - U1 is is extended to the subscriber's meter Z. If it is necessary to identify the caller, a higher negative potential - U2 is extended to identifier EM by closure of id. This potential, although it overrides - U1 by biasing off Dz (in addition to Dc and D), is effective on the meter Z provided that a metering pulse is currently being produced but is otherwise ineffective by virtue of its relatively short duration.

Title: Device for a track packing machine
IPC: E01B27/16
Filed: 1958-09-12
Abstract: 853,117. Railway track packing machines. PLASSER, F., and THEURER, J. Sept. 12, 1958 (Sept. 19,1957], No. 29299/58. Class 104 (2). Apparatus for a track packing machine having tools 4 which are movable in opposite directions and are mounted in pairs opposite one another on a vertically adjustable tool carrier 2 and also having a vertically adjustable support, a piston 13, for the tool carrier which rests on the support in the working position, the depth to which the tools penetrate into the ballast being adjustable by means of the support characterized in that adjustment of the support for the tool carrier is controlled automatically by the working tools and is effected over a range limited by the maximum and minimum necessary depths of penetration of the tools. The tools 4 are pivoted to holders vibrated by an eccentric shaft 6 and are pivoted to cylinders 7 on the tool carrier. The tool carrier is vertically adjustable on columns 3 in a chassis 1 mounted on wheels to run on rails 11. Fixed pistons 81 divide the cylinders into two chambers 71, 7<SP>11</SP> and fluid from a reservoir 171 is fed via a pipe 9 or 10 to move the tools apart or together. The cylinders slide over the fixed pistons. Initially the tools are lowered to the greatest depth of penetration, the tool carrier then resting on a flange on a screw 16 adjustably positioned in the piston 13 moving in a cylinder 14 on the chassis. Maximum excess pressure in the chambers 7<SP>11</SP> is preset by adjusting a spring 22 acting on one end of slide valve 21 in a valve 20 which normally cuts off the supply of fluid to the pipe 24 supplying fluid to the cylinder 14. The valve 20 is connected to the pipe 10 and a non-return valve 25 passes fluid from the cylinder 14 to the pipe 10 which has a return pipe to the reservoir, when the pressure in the chamber 7<SP>11</SP> increases sufficiently to move the slide valve against the action of the spring, fluid enters the pipe 24 and flows to the cylinder 14 raising the piston 13 and hence the tool carrier rises until the tools reach the lower level of the sleepers the piston then striking an abutment of the cylinder. If the tools are synchronously operated the depth of penetration into the ballast may depend on the spacing of the tools. If the tools are asynchronous individually movable, then the depth of penetration may be regulated by the resistance occurring depending on the actual degree of consolidation of the ballast. The magnitude of the pressure of the tools may also depend on the depth of penetration and/or spacing of the tools.

Patent GB-905013-A (GB)
Title: Improvements in or relating to the manufacture of cyanuric acid
Inventor: CHRISTMANN LUDWIG JACOB
Filed: 1958-09-15
Abstract: Cyanuric acid is prepared by heating a mixture of urea and an ether-alcohol of formula H(CH2)m (OCH2,CH2)nOH, where m = 0, n = 1 -17, and m + n = 2 or more, to liberate ammonia and form a homogeneous solution and further heating the solution at 200 DEG -250 DEG C. to precipitate cyanuric acid, which is separated.  The homogeneous solution is stated to be a "carbamate" of the ether-alcohol, which may be one or more of the methy, ethyl, propyl, butyl, or hexyl mono-ethers of mono-, di-, tri-, or polyethylene glycols, or di-, tri-, or poly-ethylene glycols.  The further heating of the homogeneous solution at 200 DEG  - 250 DEG C., with further NH3 evolution may be after the addition of further urea if such addition is necessary to ensure a total content of more than 1 mole of urea, per mole of ether-alcohol.  The cyanuric acid is separated by adding a solvent for the "carbamate", e.g. primary alcohols of 1 - 3 C atoms, such as methanol.  Repeated addition of urea to the mother liquor from the separation permits continuous operation.
