Title: Improvements in or relating to automatic water flow control units and water supply valves
IPC: E03D5/02
Filed: 1966-01-20
Abstract: 1,067,890. Valves. I. KENNISON. April 14, 1966 [Jan. 20, 1966], No. 2587/66. Heading F2V. A cistern supply-valve embodies a cylinder 157 with a mains inlet 167 and a chamber 183 leading to the cistern 178; the cylinder 157 houses a two-part nylon piston 155 with an air space 169 and a depending hollow-rod 156 with a lateral discharge port 171, the rod being slidable in a bore through a wall 189. The latter also has passages 177 connecting the space beneath the piston to the chamber. The piston is formed with a reduced crown having radial ports opening into the hollow rod 156. When the cistern water is below a given level, the mains pressure lowers the piston until the radial ports are below a reduced cylinder portion 153 and the discharge port 171 is disposed in the chamber 183 and the cistern commences to fill. Upon the given level being attained the water rises through the passages 177 to lift the piston and so close-off the radial ports as well as retracting the rod 156, whereby the port 171 is masked by the wall 189.

Title: Improvements in or relating to boats
IPC: B63B1/12
Filed: 1955-01-31
Abstract: 792,317. Single and twin hull boats. COCKBURN, D. H. Jan. 30, 1956 [Jan. 31, 1955], No. 2786/55. Classes 113 and 114. In a boat having a plane planing surface 14 which tapers fore and aft of the centre of buoyancy, said surface is inclined downwards in the rearward direction at a small angle (between 1 and 8 degrees). The curve of successive submerged cross-sectional areas 18 taken normal to the longitudinal axis of the boat conforms substantially to a versed-sine curve for the length forward of the centre of buoyancy and to a trochard curve for the length aft of the centre of buoyancy, In one embodiment the planing surface is narrower than the width of the hull, the sides of the hull being bulged outwards above the water line. In other embodiments hulls with planing surfaces according to the invention are incorporated in a twin hull motor boat and in a catamaran type sailing boat. According to the Provisional Specification a device for steering and lateral resistance comprises two thin vertical plates, one immersed forward and one aft of the centre of the sails, which plates are pivoted and joined together by a connecting rod, a tiller being fitted to the aft plate. The plates are normally in line but move in unison when the tiller is operated, the front plate pulling the bow in one direction and the rear plate moving the stern in the other.

Title: A new or improved method of boring
IPC: B23B29/034
Filed: 1932-01-30
Abstract: 396,102. Boring; boring - heads. KRAUSE & CO. AKT.-GES., E., 13, Franz÷sische Strasse, Berlin. Jan. 30, 1932, No. 2888. Convention date, Feb. 2, 1931. [Class 83 (iii).] In a method of finishing work which has been roughly bored, such as engine cylinders, bearings &c., the work is re-bored with an end cutting tool at a high cutting speed and with a minimum rate of feed. When the work consists of a ferrous metal a cutting speed of about 80-200 metres per minute is used and the tool is made of a hard alloy such as that known under the Registered Trade Mark Widia or other hard metal whilst for non-ferrous metals such as brass, white-metal &c. the cutting speed is from 100-800 metres per minute and the too] is of diamond. The axial feed of the tool, which is preferably automatic, is about 0À01-0À2 mm. per revolution and the depth of cut preferably does not exceed 0À3 mm. A tool suitable for use with the method comprises a cutter 1 secured within a body 2 by a screw 7 and adjusted radially by screws 5, 6. The body has a conical shank 3 for mounting in the drill-spindle 4. The cutter is ground as shown in Fig. 4, the angles between the faces near the cutting edge being obtuse so as to make the point of the tool rigid, and the centrifugal action on the tool at high speed causes it to run true.
Patent GB-372316-A (GB)
Title: Improvements in or relating to the heat treatment of rails such as railway or tramway rails
IPC: C21D9/04
Filed: 1931-01-29
Abstract: In the heat treatment of rails the rail is allowed to cool gradually after heating until substantially all of the metal of the web and the flanges has cooled to a temperature below the critical range, and then before the metal of the head has cooled to the critical range the entire rail is rapidly cooled by quenching in an aqueous medium. Before the major part of the head of the rail has dropped through the blue-heat zone, i.e. about 300 DEG  C., the temperature of the rail is equalized by immersing it in a bath of molten lead for a few minutes.  The rail is then transferred to a furnace, maintained at a temperature of about 538 DEG  C. for a period up to 3 hours and then withdrawn from the furnace and cooled in air.

Title: Non-flbrous tubing and process for its production
IPC: F16L11/04
Filed: 1931-01-30
Abstract: Non-fibrous tubing which may be used for insulating electric wires is produced from dissolved cellulose derivatives, more particularly acetyl-cellulose and nitrocellulose, with or without the addition of softening agents, coating a rod-shaped core with the cellulose solution by dipping, spraying, &c., allowing the coating to solidify, and repeating these operations until the coating has attained the required thickness, whereupon it is removed from the core.  The core may be provided with an initial thin layer of grease to facilitate removal of the tubing.  Long lengths of tubing may be made by assembling short lengths end to end on connecting cores, applying cellulose to the cores between the ends of the previously formed lengths, and then removing the said cores.  Alternatively the lengths may be fed end to end continuously to a longer core and provided with an external connecting layer of cellulose.  In a modification a short length is formed and removed from its core with the exception of one end, after which a further length is formed on the core to overlap the previous one; this is repeated until the tube is of the desired length, whereupon its surface is rendered uniform by spraying or by passing it through a cellulose varnish and then a wiping nozzle.ALSO:Non-fibrous tubing which may be used for insulating electric wires is produced from dissolved cellulose derivatives, more particularly acetyl-cellulose and nitro-cellulose, with or without the addition of softening agents, coating a rod-shaped core with the cellulose solution by dipping, spraying, &c., allowing the coating to solidify, and repeating these operations until the coating has attained the required thickness, whereupon it is removed from the core.
