Abstract: 1,016,162. Piston rings. J. J. M. A. TOUSSAINT. July 9, 1962 [July 8, 1961], No. 26268/62. Heading F2T. A composite piston ring comprises two subrings each divided into two or more segments, the segments in one sub-ring being radially overlapping and the segments in the other subring being axially overlapping. The sub-rings may be axially or radially arranged in the piston ring groove. Each radially arranged sub-ring may be further divided into axially arranged secondary sub-rings. The sub-rings may have a rectangular cross-section, a channel-shaped cross-section or an L-shaped cross-section. In Fig. 5, a radially outer sub-ring A is nested within a channel-shaped inner sub-ring B. In Fig. 7, the inner sub-ring B has a portion received within the channel-shaped outer subring. In Fig. 8, a sub-ring B is enclosed by radially inner and outer sub-ring A, C and transmits pressure from an expansion spring bearing on the sub-ring C to the sub-ring A. When an expansion spring is provided in the piston grease, the radially inner sub-ring may be grooved on its inner periphery to accommodate it. The expansion spring may be given an undulating form bearing alternately against the inner sub-ring and the bottom of the groove in the piston. Alternatively, the expansion spring may be in the form of a leaf-spring secured to the inner periphery of the inner subring.

Title: Improved process for the hydrogenation of unsaturated aldehydes
IPC: B01J23/70
Filed: 1948-10-13
Abstract: The vapour phase hydrogenation of saturated and ethylenically unsaturated aldehydes and ketones is effected with a finely-divided hydrogenation catalyst suspended in an inert medium which is liquid but less volatile under the reaction conditions than the reactants and desired reaction products. Suitable media are vegetable oils such as cotton seed oil, high boiling hydrocarbon oils such as paraffin, hydrogenated styrene dimers and trimers, liquid silicones, high-boiling polyglycol ethers, and esters such as dioctyl phthalate. Lower boiling media such as butanol may be employed if they are separated from the effluents and returned.  Generally, temperature is 80-300 DEG  C. and pressure at least atmospheric.  The medium is preferably freed from sulphur and water by catalytic hydrogenation at 120-300 DEG  C., if desired simultaneously with the preparation of the catalyst. Resin formation on the catalyst during the reaction is suppressed by using a silicone such as a dimethylpolysiloxane or a medium such as a polyether, e.g. a polyglycol ether, which is a resin solvent.  Acrolein, crotonaldehyde, ethyl propyl acrolein, a -methacrolein, a -neopentyl acrolein, a -methyl, b -tert. butyl acrolein, mesityl oxide, a - and b -ionones, ethylidene-acetone, propionaldehyde, butyraldehyde, and ethyl hexaldehyde are specified reactants.  Catalysts include copper, Raney nickel, nickel-kieselguhr, copper chromite, platinum, and palladium.  In examples: (1) a copper-kieselguhr catalyst is reduced in paraffin at 260 DEG  C., and crotonaldehyde then passed in from a preheating vessel through which the hydrogen passes before entering the reactor at 210-220 DEG  C., butyraldehyde and butanol being formed; (2) and (5) a suspension of a similar catalyst in a silicone is used for the same reaction; (3) wet crotonaldehyde is evaporated and passed with hydrogen into a suspension of Raney nickel in butanol, the gaseous products being fractionated to return entrained butanol; (4) Raney nickel is suspended in dibutyl phthalate and hydrogen and acrolein vapour fed below the liquid surface; (6) ethyl hexanol is the medium in a similar hydrogenation.

Abstract: 857,285. Ventitators. BARKER, W. H., and BARKER, D. R. Sept. 11, 1957 [Sept. 3, 1956; Jan. 25, 1957], Nos. 26852/56 and 2741/57. Class 137. A damper for controlling air flow in a conduit comprises a number of spaced apart, parallel louvres 1, each comprising a pair of blades 4 arranged to form a V in cross-section, the apices of the louvres all pointing in the same direction, which is preferably against the direction of air flow. Each louvre is formed of springy material shaped around and supported by rods 7, the ends of which are mounted to slide in slots 8 on opposite sides of the casing of the duct 2. The louvres rest at their ends on pins 5 provided on opposite side walls of the casing so that the rods 7 ride in slots 8. A rectangular frame formed of opposite limbs 10 with connecting limbs rests on the ends of the louvres and is mounted by means of screws 15 passing through screw threaded holes in lugs 14 attached to the frame and through holes in lugs 16 attached to the duct. Depression of one end of the frame relatively to the other by rotation of one of the screws causes the frame to swing downwards about the other end forcing the louvres to splay outwards by progressively different amounts from one end of the damper to the other so that the size of the gaps between the louvre increases progressively as shown in Fig. 4. In a modification a centrally placed bar having V-shaped notches to fit the apices of the louvres acts as the controlling member. In place of blades formed of a single piece of springy material, separate blades may be hinged together to form each V-shaped louvre, the blades being urged together by a spring.

Ceramic, or powdered non-plastic ceramic material to which a binder has been added, is formed into a pre-shaped mass, by passage through a screw-extrusion machine, then immediately vacuum degassed, and subsequently extruded to form the desired shape, whilst still in the degassed state, by passage through an extrusion press. Material is fed into cylinder 12 via inlet 16 and rolls 52 (Fig. 3, not shown), then extruded by screw 14 through slitshaped openings 20 into the vacuum degassing chamber 22. After degassing the material is fed through further rolls to screw member 24 and then conveyed by transfer piston 32 from the preshaping chamber 28, where it is preshaped to a form suitable for loading, to the pressing chamber 36 of an extrusion press 30 whilst still under vacuum. It is then extruded by piston 38 out through nozzle 40, into the desired final shape. In alternative embodiments, the transfer piston is omitted (Figs. 3 to 5, not shown), and a single screw extrusion stage is utilized (Fig. 6, not shown). Examples and comparisons of the extrusion of kaolin, alumina powder and uranium or thorium dioxide powder by this and other customary methods are given.

Abstract: 1284634 Regulating I C engine fuel supply BORG WARNER CORP 4 June 1970 [25 June 1969] 27099/70 Heading F1B [Also in Division G3] In a fuel system for an I C engine with an inlet manifold 12 and inlet valve 15 fuel is supplied to an injection nozzle 16 from a pump 18 by a fluid logic switch 19 (see Fig. 5) which normally causes the fuel to flow along by-pass line 21 but on receipt of a signal pulse in line 26 and for the duration of the signal causes fuel to pass along line 28 to the nozzle. The signal pulse is formed by a camshaft/crankshaft driven semicylindrical disc which is connected between a pneumatic pressure source 36 and a fluid amplifier 43 to feed pulses whose frequency is dependent on speed thereto. The output line 54 of the latter is connected directly to line 62 of a pulse forming amplifier 44 and via a variable-volume chamber 67 to line 68 of the amplifier 44. Piston 77 is moved by the vacuum in the inlet manifold to vary the volume and thus the time delay between the two pulses fed to amplifier 44 according to engine load. The frequency of the pulses fed to line 26 is thus dependent on engine speed while the duration of the pulses is dependent on engine load. The fluid logic switch 19 may be replaced by a threeway switching valve 119, Fig. 4, which on receipt of a pulse at 126 disconnects line 122 from line 124 and connects it to line 129. Both the fluid switches of Figs. 4, 5 may be bi-stable and the signals on lines 65, 64 are then fed directly to lines 26, 27, amplifier 44 being dispensed with.

Oct. 4, 1932, No. 27590. [Class 40 (v).] A push-pull combination 1, 2 is combined with means such as a diode rectifier 10, so that as the input signal voltage increases the applied grid-bias is automatically brought nearer the lower bend of the characteristic curve, so that as the input rises the combination automatically changes from class A to class B amplification. The output voltage is applied through a condenser 8 and a resistance 17 to the diode 10, and the resulting voltage across a resistance 12 is applied to the grids of the two amplifiers. The derived voltage may be restricted to the desired value by means of a rectifier associated with a second resistance 13, the voltage across which is applied across the grid and cathode of both valves in such a sense that as the input energy rises the grid-bias is increased. In Fig. 2 a second diode 21 serves to limit the variation in the biassing potential applied to the push-pull valves.
