Filed: 1972-01-28
Abstract: 1367095 Spray carburetters W H PHILLIPS 28 Jan 1972 [17 Feb 1971] 4855/71 Heading F1B A fuel injector comprises a throttle incorporating a butterfly valve 3, Fig. 1 wherein fuel passes to the throttle passage through a duct 6 extending longitudinally through the valve spindle, the spindle duct communicating with a fuel supply duct 11 and the ducts being relatively movable to control the fuel. An electrical or mechanical pump supplies fuel via a pressure regulator 18, to duct 11 and thence via ducts 6 and 7 in the butterfly valve 4 to the induction passage 71. The valve spindle is rotated by an arm (14) Fig. 4 (not shown) attached to collar 13. The eccentric arrangement of ducts 6 and 11 relative to the axis of spindle 8 permits control of the fuel supply, in proportion to the opening of the butterfly valve, by misalignment of the ducts. In modifications the fuel-pressure is regulated in dependence on inlet manifold vacuum and a pulsation damper is fitted to duct 16.

Title: Elevator system
IPC: B66B3/00
Filed: 1964-02-05
Abstract: 1,059,283. Lift control systems. L. W. PORT. Feb. 5, 1964, No. 4894/64. Heading B8L. In a multi-car automatic passenger-lift control system, instead of having floor selector buttons in the car, an array of floor selector buttons is provided at each landing. An intending passenger presses the button for the floor to which he desired to travel, and this signal is registered by the control equipment which halts a car at the floor to allow the passenger to board it, and then travels automatically to the selected floor without further action on the part of the passenger. Preferably an indicator panel is provided at the landing to show waiting passengers which floor the particular car is travelling to. One of the car selector relays is designed to operate more quickly than the other, so that when both cars are at rest the car with the faster selector answers the call. In a large installation a computer may be used to register the calls and select the most efficient car movements to answer the calls in accordance with predetermined traffic patterns. Preferably the car is provided with a " next floor stop button " to enable the car to be stopped at a floor other than that originally selected. A relay control system for a 2-car 3-floor lift system is described, Figs. 1-5 (not shown).

A composition, which may be used as a filling for fireworks, for flares and coloured lights, or in line-throwing rocket propellants and smoke generators, comprises a resin as fuel and binder, an inorganic oxidant and a hardener for the resin. The resin is either an epoxy resin, an alkyd/isocyanate resin, a polyester/styrene resin or a polyester/vinyl toluene resin. Additional substances are added as required to give the composition the desired characteristic. Preferably the epoxy resins are fluid at ambient temperatures and the other constituents are in dry powder form before mixture with the resin. Ethylene diamine, diethylene triamine or an amine adduct may be used as the hardener. For flares magnesium powder and strontium oxalate or barium oxylate may be added, while for coloured lights aluminium powder with a colouring substance may be added. In an example 60 parts by weight of strontium nitrate are mixed with 16 parts of magnesium powder, 16 parts of an epoxy resin and 1.6 parts of an amine hardener to produce a coloured flare composition. In an alternative composition, strontium nitrate is replaced by strontium oxalate and potassium perchlorate is included. A coloured light composition given is 18 parts by weight ammonium perchlorate, 5 parts barium oxalate, 4 parts aluminium powder, 3 parts epoxy resin and 0.3 parts amine hardener. Strontium oxalate may replace the barium oxalate. Ammonium perchlorate 9 parts by weight, epoxy resin 2 parts and amine hardener 0.3 parts may be used as a rocket filling. Accelerators such as zinc naphthenate may be added to the binder, so that it hardens at room temperature or the binder may be hardened by heating at 100‹C. for 1 hour or 120‹C. for half-an-hour.
