Patent GB-1079170-A (GB)
Title: Improved system for controlling a pump in response to fluid delivered thereby
Inventor: KAJI WALTER ULYSSES
IPC: F04D13/04
Filed: 1965-09-10
Abstract: 1,079,170. Metal pouring apparatus. METAL PUMPING SERVICES Inc. Sept. 10, 1965, No. 38730/65. Heading B3F. Apparatus for delivering accurately metered amounts of a fluid such as molten metal from a reservoir 12 into the shot well of a diecasting machine, comprises a constant speed pump 13, operated through a time control circuit, to supply molten metal through a conduit 27 into the shot well 34. The closing of the contact 39 actuates a first timer 41 by closing the switch 42, which in turn actuates the solenoid valve 36 to start the pump motor 30. Molten metal is thus pumped through the conduit 27 and as it is discharged from the spout 33 contacts a detecting probe 43 thereby completing the circuit to actuate the second timer 46. The pump is operated until the timing phase of the second timer 46 expires whereat, the switch 50 is opened to stop the pump. In this arrangement only the quantity of molten metal discharged into the shot well is determined by the timer, the supply from the pump and the amount residual in the conduit 27 being constant. The timing phase of the first timer is slightly longer than that of the second timer so that in the event of failure of the latter the first timer would effect the stopping of the pump.

Such an arrangement is preferably used in a coin operated telephone to indicate to an operator that such a telephone is being called. Exchange equipment 1 is connected to a substation in which the normal cradle switch arrangement is modified by the addition of an extra contact 15. When the hand set is on hook a capacitor 11 is connected to the wire 12 via resistor 14 and contact 15. When the hand set is lifted, the line wire 2 is connected to the wire 12 and an oscillator unit 10. Capacitor 11 then charges through the oscillator unit 10 and thereby causes a decaying tone to be transmitted to the exchange operator. The tone terminates when the capacitor 11 is fully charged. When the hand set is replaced the capacitor discharges via resistor 14 and wire 12. The oscillator is preferably a simple semi-conductor circuit, which is operable at the line voltage. Alternatively a low voltage oscillator may be used in conjunction with a Zener diode and series resistance to give a short but constant amplitude tone to the line.

Title: Method for making alcohols by ionizing radiation
IPC: C08F2/54
Filed: 1964-10-02
Abstract: Telomerized alcohols are obtained by irradiating with high energy ionizing radiation a flowing mixture of reactants in the vapour or liquid phase, the reactants comprising an alcohol having fewer carbons than the product alcohol and an olefin, the dose rate of the radiation being 1 to 40 megarads/hour and the radiation being applied for a period of 10 secs. to 10 mins.  The reaction in the vapour phase is suitably effected at approximately atmospheric pressure and at a temperature sufficient to maintain the vapour phase and the concentration of alcohol with respect to olefin is preferably in an overall molar range of 0.5:1 to 40:1. The starting alcohol may be a C1- 6 saturated aliphatic alcohol and is preferably an alcohol containing a tertiary hydrogen atom and the hydroxyl group on the same carbon atom; the starting olefin is preferably a C2- 6 1-olefin but it may contain up to 12 carbons and it may also be a diolefin. The high energy ionizing radiation may be ionizing particle radiation, e.g. accelerated electrons, nuclear particles including protons, fast neutrons, alpha and beta particles, deuterons and fission fragments, and ionizing electromagnetic radiation, e.g. gamma rays and X-rays.  The energy level at which the radiation is employed is suitably 1 kev. to 30 mev.  The reaction in the liquid phase is suitably effected at room temperature to 200 DEG  C. at a pressure which is approximately atmospheric and the concentration of alcohol with respect to olefin may be in a molar range of 15:1 to 500:1.  The starting alcohol may be a C1- 12 saturated aliphatic alcohol and is preferably an alcohol having a tertiary hydrogen atom and the hydroxyl group on the same carbon atom; the starting olefin and the radiation may be the same as that employed in the vapour phase reaction.  In the vapour phase reaction, energy transfer substances, e.g. rare gases or solids of high surface area may be employed.  In the examples, mixtures of isopropanol and ethylene are reacted together.

Abstract: 1,078,750. Tobacco smoke filters. P. LORILLARD CO. Oct. 1, 1965 [Oct. 22, 1964], No. 41751/65. Heading A2C. A method of making tobacco smoke filters comprises introducing into a mould an intimate mixture of a granular absorbent material and a thermoplastic bonding agent, heating the mixture in the mould to soften the agent and band the material together to form a self-sustaining rod, ejecting the rod from the mould, heating the rod to soften the agent throughout the rod, and cooling the rod to bond the granular material together. The granular material may be activated charcoal, silica gel, absorbent silica or calcium carbonate, and the bonding agent may be polyethylene, polyvinyl acetate, polyvinyl alcohol, polypropylene, polyvinylidene acetate, natural gums, resins and waxes. The amount of bonding agent used may be up to 15% by weight of the mixture. Apparatus for carrying out the method comprises a hopper 20, mounted on a frame 10, from which the mixture is ejected by a pair of plungers 21 and 22 into a heated mould 23 which is provided with two pairs of moulding cavities 24, 25 and 26, 27. The mould is movable transversely to dispose one or other pair of cavities to one side of the plungers 21 and 22 so that material in the cavities can be ejected by plungers 28 and 29, or 30 and 31 from the opposite pair of cavities on to one or other conveyer belts 32 and 33. Back-up plungers 110, 111 are provided for the plungers 21 and 22. The ejected rods are conveyed through heating tunnels 34 and 35, Fig. 5 (not shown), to further conveyers 138, 139 where cooling takes place. The various plungers and the mould, together with an agitating device in the hopper for ensuring even distribution of the material in the mould are operated in timed relationship through a system of oscillating levers, as 104, having cam followers which cooperate with cams driven through chains and sprockets from a reduction gear coupled to an electric motor, Figs 2-4 (not shown): In a second embodiment, Figs. 6-13 (not shown), a plurality of moulds are mounted on an intermittently rotating mould carrier. The carrier is mounted for rotation between two hoppers from which material is fed into the mould at one point, ejection of the rod taking place at a different point of rotation of the carrier.
