Title: A process for the preparation of keto-ethers
IPC: B01J31/08
Filed: 1963-04-16
Abstract: Keto-ethers of formula <FORM:0986714/C2/1> where R is a substituted or unsubstituted hydrocarbon group having 1-5 carbon atoms, any substituents being non-reactive under the reaction conditions, R1 is a hydrogen atom or alkyl group, and R11 is an alkyl group, are prepared by reacting a primary alcohol ROH with an a ,b -unsaturated alkenone containing up to 10 carbon atoms and having the formula <FORM:0986714/C2/2> in the liquid phase, at a temperature of 0-100 DEG  C., in the presence of a strongly basic anion exchange resin as hereinafter defined.  Suitable primary alcohols are primary aliphatic alcohols, e.g. methanol, ethanol, propanol, butanol, isobutanol, pentanol, allyl alcohol, methallyl alcohol, crotyl alcohol, isocrotyl alcohol and propargyl alcohol, and alcohols containing ether and phenyl groups which are inert under the reaction conditions, e.g. benzyl alcohol, ethylene glycol monomethyl ether and ethylene glycol monoethyl ether.  Examples of suitable a ,b -unsaturated alkenones are methyl vinyl ketone, 3-penten-2-one, mesityl oxide, homomesityl oxide, 3-hexen-2-one and 2-methyl-3-hepten-5-one. Equimolar amounts of alcohol and alkenone may be used, but preferably one of the reactants is used in excess.  The strongly basic anion exchange resins used in the invention are those having a pKb10 of greater than 1. Synthetic resinous ion-exchange resins having phosphonium or sulphonium functions are examples of such materials.  They may be used in an amount of 0.1 to 20% by weight based on the alkenone, but greater or lesser amounts may be employed.  They may be employed as dispersed solids, in suspension, or as packed beds, through, or over, which the reactants are passed.  The reaction may be conducted as a batch, semi-continuous or continuous process, preferably under anhydrous conditions.  In the preferred embodiment of the invention, a mixture of alcohol and alkenone is passed continuously through the catalyst bed, and the ketoether is separated from the resultant mixture.

Title: Apparatus for supplying liquid carbon dioxide
IPC: F17C7/02
Filed: 1973-03-28
Abstract: 1429678 Automatic control of level DISTILLERS CO (CARBON DIOXIDE) Ltd 18 Jan 1974 [28 March 1973] 14925/73 Heading G3R [Also in Division F4]  In apparatus for delivering liquid CO 2  from a heat insulated reservoir 1 through a discharge pipe 5, 5' to a delivery point at 8, a container 7 is connected in the discharge pipe for removal of gaseous CO 2  through an outlet pipe 12 with a valve 11 controlled by a unit 31 which opens the valve when the gas reaches a predetermined volume in the container. As shown the gas is passed to an accumulator 14 and thence to a cooler 17, and is returned as liquid to the reservoir 1. Simpler installations are, however, envisaged in which the gaseous CO 2  is vented to atmosphere or directly to the top of the reservoir. The reservoir is refrigerated by a coil 3. The delivery point is a metering jet 8 connected to a snow-making horn 9, but may alternatively be a connector for filling cylinders or the intake of a rotory pump.  The valve 11 is a solenoid valve and may be controlled by a float-operated switch. Preferably however, the container 7 has a tubular wall 22 forming the outer electrode of a coaxial capacitor, the inner electrode being formed by a perforated tube 27. The two electrodes are connected through a cable 29 to the resonance circuit of a Colpitts oscillator, Fig. 3 (not shown) in the control unit 31. When the container 7 is full of liquid CO 2 , the capacitance between the electrodes 22, 27 is enough to block the oscillator so that there is no input to an amplifying (T2), and a switching transistor (T4) controlled thereby is OFF. The emitter circuit of the transistor contains the coil of a relay (R) with normally open contacts (Ra) in series with the solenoid of the valve 11 which is therefore closed. As gaseous CO 2  collects in the container 7, the liquid level and the capacitance drop with the eventual onset of oscillation. The relay (R) is thereby closed, opening the valve 11  to vent the gas and opening auxiliary contacts (Rb) to disconnect a capacitor (C7) from the oscillator circuit. Oscillation therefore continues until the capacitance between the electrodes 22, 27 increases sufficiently, as the liquid level rises, to offset the effect of the capacitor (C7).

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M7/12
Filed: 1920-06-03
Abstract: 146,093. Ateliers H. CuÚnod, Soc. Anon. June 23, 1919, [Convention date]. Spray carburettors.-In a carburettor of the kind in which the size of the fuel orifice is varied simultaneously with the passage around the nozzle, the device controlling the fuel orifice is adapted to be operated independently by hand to increase the fuel supply at starting. The size of the fuel orifice is also varied independently by the engine suction, to prevent an excessive flow of fuel when the suction is high. The casing a is formed in one with the float chamber d and encloses four symmetrical pieces j<1> which produce the variable passage i around the nozzle h. These pieces have, formed throughout their depth, slots i<2> which engage pins fixed to the bottom a<5> of the casing a. Further, each piece has on its lower face a groove which engages a transverse projection j<4> on a small plate j<5> on an adjacent piece. The bottom of each piece has also a pin which engages a cam-groove k<9> in a plate k which can be rotated by an arm m. By rotating the arm m, the pieces slide over and partly rotate about the fixed pins, and as a consequence the size of the passage j is varied. The fuel nozzle h has sliding over it a sleeve l which carries a fuel-control valve i, and is slotted at its upper end to allow the fuel to escape. The sleeve has an arm l<2> having an inclined lower face resting on a projection 14<1> on an arm 14. The arm 14 is secured to a bent arm 15 which rests through a screw 16 on the upper plate of a flexible chamber 1. This chamber is mounted on an arm 3, and its interior communicates through passages 2<1>, 3<1>, 4 with the induction passage at the bottom of the tapered outlet b<3>. As the plate k is rotated by the, arm m, the arm l<2> is turned by a pin r, and the sleeve. l is raised to vary the fuel outlet. If the suction becomes high, the upper plate of the chamber 1 is drawn down and the sleeve l and fuel valve are lowered. To raise the sleeve l to increase the fuel supply at starting, a hand-operated lever 21 is provided having a lug 20<1> adapted to lift the arm 14. Specification 135,453 is referred to.

Abstract: 680,256. Pulse generating circuits. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. June 18, 1951 [June 19, 1950], No. 15313/50. Class 40 (vi). In a pulse generator comprising an electronic discharge tube in which the current build-up through one section is slower than in other sections a capacitor is connected to by-pass the section in which the build-up is slower so that the rate of build-up and thus the steepness of the leading edge is increased. The Figure shows a pulse generator in which pulses from a triggering circuit are applied at T to trigger a hydrogen-filled thyratron V1, the pulse width being determined by the pulse reflected from the delay line DL. The current build-up in the grid cathode section of the tube which would be more slow than in the grid-anode section is prevented from having a deleterious effect on the steepness of the leading edge of the generated pulse by provision of capacitor C1 which bypasses the grid-cathode section of the tube. A saw-tooth waveform may be applied at T so that the thyratron fires at a pre-determined point along its sloping edge. Since the trailing edge of the generated pulse is derived from the leading edge of the pulse this is also steepened by the provision of capacitor C1.
