Title: Projectiles for hunting fishes or marine mammals
IPC: F42B30/14
Filed: 1954-06-08
Abstract: 758,574. Whaling projectiles. BLACKER, L. V. S. June 8, 1955 [June 8, 1954; Feb. 18, 1955], Nos. 16837/54 and 5003/55. Class 9(1) A projectile for injecting into whales a gas to produce inflation and a paralysing liquid comprises a metal bottle 4 through which extends a guide tube 6 housing an injection tube 8. The bottle is charged with a gas, e.g. nitrous oxide under pressure through a non-return valve 48 and the liquid, e.g. decamethonium iodide, is housed in the tube 8. Mounted in the forward end of the guide tube is a bush 12 supporting the injection tube and abutting a sealing ring 18, which engages a shoulder 14 on the tube 8 to limit its forward movement and form a gas-tight seal. A nose-piece 20 on the forward end of the tube 8 has a circular cutting edge and barbs 24 are pivoted on lugs 23 fixed to the tube 8. A safety pin 30 passing through a metal shell 28, which encloses the nose 20, holds the injection tube 8 in the retracted position. In the rear end of the tube 8 is a spider on which is mounted a housing 32 containing a percussion cap. a fuze and a charge. The rear of the guide tube is closed by a member 36, which holds a firing pin 34 and also houses the forward end of a tail tube 38. On discharge, after withdrawal of the safety pin, the injection tube sets back relatively to the guide tube and the cap impinges on the firing pin. The fuze is then ignited and, after a given time, fires the charge to drive the tube 8 forwardly and disrupt the shell 28. The liquid is confined between two pistons, which moves forward in the tube 8 and fusible metal plugs 50, 52 are forced out of apertures in the guide tube to release the gas into the tube. When the nosepiece strikes a whale, tongues 56. soldered over outlet holes at the forward end of the injection tube, are broken. The nosepiece moves rearwardly, the tongues being pushed outwards by a ramp 58, so that the liquid is driven out through the holes, by the gas. which then escapes through the holes. In an alternative arrangement. the injection tube is driven forwards by a spring released by a catch on discharge of the projectile. Valves may be used to close the outlet holes instead of the tongues 56 and to release the gas from the bottle. Specification 573,653 is referred to.

Title: Internal combustion engine fuel supply systems
Inventor: BALLOU RICHARD PITT
IPC: F02M37/08
Filed: 1970-04-09
Abstract: 1,242,816. I. C. engine fuel systems; ignition systems. GENERAL MOTORS CORP. April 9, 1970 [April 21, 1969], No.16971/70. Heading F1B. In an I. C. engine fuel system the operation of a reversible fuel pump connected between the engine and a fuel reservoir is controlled by a switch so that on actuation of the switch to operate the engine the pump supplies fuel thereto and on actuation of the switch to stop the engine the pump withdraws fuel therefrom. Operation: When engine 12 is stopped and ignition switch 20 is in the "OFF" position the pump 18 does not transfer fuel. When switch 20 is in the "START" position the battery 30 energizes the engine starter and relays 44, 68. The energization of relay 44 closes contacts 46, 50 to cause the pump 18 to transfer fuel to the engine. The energization of relay 68 opens contact 78 to disconnect engine accessory loads and closes contacts 72, 80 to permit energization of the pump via lead 64 at battery voltage by by-passing resistor 40 and to supply ignition energy to coil 84 by by-passing resistor 86. When the engine starts and the switch 20 is placed in the "ON" position contacts 78 are closed to connect the engine accessories to battery 30 and opens contacts 72, 80 to permit energization of the motor 26 and coil 84 through resistors 40, 86 and a switch 42 responsive to the operation of the engine e.g. responsive to oil or coolant pressure or engine speed. Relay 68 gives a delayed release to maintain contacts 72, 80 closed until switch 42 closes. When the switch 20 is in the "OFF" position the relay 44 is de-energized thereby reversing the polarity of the pump motor and causing it to transfer fuel from the engine to the reservoir and the engine continues to operate until it runs out of fuel since the ignition network 82 is still energized by switch 42. Should the engine stall prior to the switch 20 being placed in the "OFF" position the switch 42 opens de-energizing the motor and ignition circuits to stop transfer of fuel thereby allowing the engine to be restarted without having to wait until the pump has refilled the carburetter. The pump may be replaced by a fluid driven pump and an engine controller utilizing fluid valves may replace the ignition switch.

Title: Improvements in or relating to the manufacture of methanol
IPC: C07C31/04
Filed: 1929-06-05
Abstract: 335,962. Dreyfus, H. June 5, 1929. Methyl alcohol.-In the production of methanol from carbon monoxide and hydrogen, the reaction gases are passed first over one or more masses of zinc oxide with or without chromium oxide, and then over one or more methanol catalysts which are sensitive to sulphur poisoning such as catalysts containing copper or manganese or their compounds. The process may be effected in an open system, i.e. not in a closed circuit. In an example, water gas or the like is passed at 50-100 atmospheres pressure through a number of reaction chambers in series, the first chamber or chambers containing zinc oxide, while the later chambers contain, for instance, a mixture of copper and zinc oxides. The reaction gases are treated to remove the methanol produced. If desired, a sufficient number of reaction chambers may be used to cause the conversion of practically all the gas mixture into methanol. Four or five chambers are usually sufficient.
