Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: CLAUDEL CHARLES HENRI
IPC: F02M5/12
Filed: 1917-03-14
Abstract: 105,904. Claudel, C. H. March 15, 1916, [Convention. date]. Spray carburettors.-Float chambers of carburettors are provided with means for closing automatically the channel communicating with the atmosphere, and that leading to the fuel nozzle, and thereby preventing escape of fuel and risk of fire in the event of the float mechanism failing, or the fioat chamber being out of its normal position. The float chamber communicates with the atmosphere through an aperture 1, Fig. 1, and a channel 2 which is controlled by a valve 3 carried by a small float 4. The passage leading to the nozzle 5 has a downward extension containing a ball valve 6 which becomes seated at 7 in the event of the carburettor becoming so inclined as otherwise to flood the nozzle. A small by-pass to the seat 7 may be provided to prevent complete stoppage of the flow of fuel. In the modification shown in Fig. 6, the ball valve is replaced by a plug valve 9 actuated by a weight 10. A further modification is described in which the top of the float chamber communicates with the induction pipe instead of with the atmosphere.

Title: Catalytic reforming
IPC: B01J21/08
Filed: 1955-02-08
Abstract: A substantially halogen-free catalyst for reforming hydrocarbon fractions (see Group IV (b)) comprises 0.05-2 per cent by weight of platinum or palladium deposited on a carrier which consists of alumina containing 7-16 per cent by weight of silica and which has a cracking activity index (measured by the "Cat. A" test) of between 6 and 20.  The carrier may be prepared (a) by mixing alumina hydrogel and silica hydrogel; (b) by grinding powdered dry alumina in a ball mill with wet silica hydrogel; or (c) by impregnating dried alumina hydrogel with an aqueous or alcoholic solution of ethyl orthosilicate.  In each case the composite is washed, dried, and calcined.  The platinum or palladium is deposited by mixing the carrier with an aqueous solution of chloroplatinic, bromoplatinic, chloropalladic or bromopalladic acid or of an ammonium salt of these acids, and then drying and reducing in hydrogen.  In order to remove substantially all the halogen, the catalyst is heated in steam at 800-1100 DEG  F. for 2-24 hours or with water at 300-800 DEG  F. under 300-3000 lb. per square inch pressure for 1-100 hours; this treatment may also be applied to the carrier before deposition of the platinum or palladium.  The surface area of the carrier may be in the range 50-500 square inch per gram.  A blend of n-heptane and cyclohexane is contacted in the presence of hydrogen with catalysts of different silica contents, and the relationship between temperature, silica content and yields of benzene and C7 isomers is shown graphically.  The catalyst may be regenerated by burning off carbonaceous deposits in a gas of increasing oxygen content at 900-950 DEG  F.ALSO:A petroleum hydrocarbon fraction boiling in the range 60-450 DEG  F. is reformed by contact with a substantially halogen-free catalyst comprising 0.05-2 per cent by weight of platinum or palladium deposited on a carrier which consists of alumina containing 7-16 per cent by weight of silica and which has a cracking activity index (measured by the "Cat. A" test) of between 6 and 20 (see Group III).  Reforming is carried out at a temperature of 700-1000 DEG  F., a liquid hourly space velocity of 0.1-10, in the presence of hydrogen under pressures of 100-1000 lbs. per sq. inch, and using a molar ratio of hydrogen to hydrocarbon of 1-20.  A blend of n-heptane and cyclohexane is contacted in the presence of hydrogen with catalysts of different silica contents, and the relationship between temperature, silica content and yields of benzene and C7 isomers is shown graphically.  In Example 3 a petroleum naphtha of boiling range 240-360 DEG  F. is converted to a high-octane gasoline.
Patent GB-745214-A (GB)
Title: Expanded thermoplastic material
Inventor: HOGG WILFRID HENRY
IPC: C08J9/30
Filed: 1953-02-12
Abstract: Expanded thermoplastic resinous material is produced by forming a froth of a plastisol of the resin, e.g. polyvinyl chloride, in the presence of a thickening agent, thus stabilizing the froth, and then heating to gel the resin.  The frothing may be carried out by incorporating a blowing agent comprising a plurality of components which on admixture in solution or dispersion liberate a gas at a temperature below that at which gelling takes place, e.g. a strong acid such as syrupy phosphoric acid and a carbonate or bicarbonate such as the sodium salt.  A specified plasticizer is dioctyl phthalate, while the thickening agent may be soluble in the plasticizer phase, e.g. aluminium naphthenate, or insoluble therein, e.g. silica, or a mixture of both.

Title: Improvements in synchronous electric time-keeping devices
IPC: G04C5/00
Filed: 1932-02-12
Abstract: 394,751. Clocks. HAMMOND CLOCK CO., 2911, North Western Avenue, Chicago, U.S.A. Feb. 12, 1932, No. 4284. Convention date, Feb. 13, 1931. [Class 139.] In a synchronous electric clock, an induction motor normally drives the hands through a maintaining spring, regulation being effected normally by a synchronous electric brake geared to the hands, and during current stoppages by a mechanical speed governor which rotates continuously with the electric brake rotor. The induction motor rotor 64, Figs. 6 and 7, drives through gearing 76, 86, 90, 92, 94, 98, 100, 104, 106, 110, 112, a spring drum 114 to wind a spring 118 therein, the driven end of the latter being geared through shaft 116 and 120, 122, 124, 126, 128, 130, 132, 134, 136, 138, 74 to the rotor 70 of a synchronous brake which with the induction rotor 64 has a common stator coil 50. The drive to the hands 40, 42, 44 is taken from shaft 108 on which gears 122, 124 are mounted. The induction motor is of the shaded pole type and therefore self starting, but the synchronous motor is manually started by depressing and then rotating a spring-pressed knob 168, Fig. 6, the rotor 70 being thereby rotated through gears 172, 132, 134, .. 74, and falling into step as it passes through synchronous speed. A hand setting knob 162 is provided. The induction motor initially rotates at a greater speed than the rotor 70 to wind up the spring, after which the two motors rotate at substantially the same speed, the spring 118 being wound as fast as it unwinds. Mechanical speed governor. Comprises a frame 352, Figs. 5 and 8, attached to a bush 354, freely rotatable on shaft 74 but resiliently connected thereto by a spring wire 382 passing through lugs 384 of the frame and loosely through a hole 386 in the shaft which carries a friction disc 394 against which the bush 354 is forced by spring 382. When the supply fails, the drum 114 is locked by pawl 178, Fig. 7, and the spring 118 continues to drive and accelerates the hands. Assuming a normal speed of shaft 74 equivalent to a supply frequency of 60~, then, when the speed has reached that equivalent to 65 ~, a weight 372 normally stressed to rest on a stop 378 by its mounting spring 370 pivoted at 368, flies outwards centrifugally until spring 370 engages a stop 380. An arm 398 pivoted at 400 and urged by a spring against a stop 406 mounted on the frame plate 24, now lies in the path of the spring end 373, and its inertia constants are so arranged that when struck the speed of shaft 74 falls to the equivalent of 55 ~. The governor acts thus continuously to give an average speed equivalent to 60 ~. In a modified form of governor, the shaft 74, Fig. 10, is resiliently coupled to an arm 192 by a spring 208, springs 196 mounted on arcuate arms 193 connected to arm 192 and bearing weights 200 being adapted to contact with the teeth of an adjustably mounted inertia wheel 332 at the appropriate supersynchronous speed.

Filed: 1972-01-14
Abstract: 1371763 Pulse generators JOSEPH LUCAS (INDUSTRIES) Ltd 14 Jan 1972 [10 Feb 1971] 4346/71 Heading G1A In a pulse generator unit suitable for controlling an internal combustion engine, an interrupter wheel 14 within a housing 10 is connected to a shaft 13 that may be rotated by the engine and has two axially spaced bands (15, 16), Fig. 3 (not shown) having alternate transparent and opaque areas the arrangement being such that rotation of the wheel 14 will interrupt light passing from sources 18 and 19 to photo-cells 21, 22 (all of which are attached to the housing 10) and light from a light source 20 passing to photo-cell 17 (both of which are attached to a stator 12 that is pivotable with respect to the housing). The photo-cells 17 and 19 both receive light that has passed through the same band (15) and the phase relationship between the trains of pulses produced by the two photo-cells depends upon the angular position of the stator (which may be connected to the throttle) relative to the housing. The photo-cell 18 receives light that has passed through the band 16. The number of opaque parts in the band 15 may be equal to the number of cylinders in the internal combustion engine, where as the band 16 may have a substantially greater number and the outputs of the three photo-cells may be connected to a grating circuit which is arranged to "gate" the output of the photo-cell 18 to an electronic counter, for controlling fuel injection, when an output is provided by the photo-cells 17 and 19 Figs. 4d and 4e (not shown). Other uses for the pulses produced by the generator are disclosed, concerning speed measurement, or providing a pre-set pulse for ignition signalling. A further photo-cell (not shown) may be used to provide a single pulse per revolution of the interrupter wheel 14 for signalling the start of each engine cycle, furthermore the band may be replaced by other light modulating means such as those using reflection or refraction.

Abstract: <PICT:0936421/III/1> <PICT:0936421/III/2> <PICT:0936421/III/3> A diffusion cell for separating a mixture of gases into at least two of its constituents by diffusion of such mixture through a porous wall or walls, comprises means for circulating the gaseous mixture near the porous wall or walls from the cell inlet to the cell outlet, and deflecting members constructed so as to create transverse flow components in the gaseous mixture, wherein the deflecting members are disposed exclusively in a central region of the cell when viewed transversely, so as to reserve for the gaseous mixture a rectilinear path along the porous wall or walls, the said path directly connecting the cell inlet to the cell outlet and having a cross-section at least equal to a third of the total cross-section of the portion of the cell within the porous wall or walls.  In the diffusion cell illustrated in Fig. 1, the gaseous mixture flows through the inlet conduit 1 to the chamber 2 and the gaseous portion which has not diffused through the porous walls 3 leaves at 4.  The gas that has diffused through 3 is collected in chamber 5 and withdrawn through 6.  A rod 10 carrying a plurality of coaxial discs 9 is fixed in a central position in the cell and the discs form obstacles which create in the gaseous stream transverse flow components capable of producing the desired turbulence. Alternatively, the obstacles are formed by a wire 12 helically wound with a variable or constant pitch about a cylindrical support 13 (see Fig. 3).  In other embodiments the cells are of rectangular crosssection, instead of tubular shape as in Figs. 1 and 3, and the obstacles are formed by transverse rounded bars or a plate 16 (see Fig. 6) some portions of which have been cut and twisted both upwardly and downwardly.
