Title: Improvements in or relating to control linkages
IPC: G05G7/02
Filed: 1947-03-26
Abstract: 631,000. Reversible - pitch propellers. BREGUET, L. March 26, 1947, No. 8254. Convention date, April 5, 1946. [Class 4] [Also in Group XXIV] Mechanism for moving a member first in one direction and then the other from continued movement in one direction of a control member, applicable to the interconnection of the propeller pitch and throttle controls of aircraft, enabling the pitch to be reversed by a return movement of the pitch control lever while at the same time closing the throttle as its lever passes through the extreme idling point, after which the throttle is opened as the pitch is reversed, comprises a control member 25, Fig. 1, adapted to be directly coupled by a ball member 29 to the actuated member 32 or indirectly coupled through an auxiliary member 33 geared to the control member 25 through rack-and-pinion gearing 26, 37, 34. Each of the members 25, 33 has a notch 28 or 36 for receiving the ball 29, which is carried by a cage 31 secured to member 32, and a stud 27 or 35. From the neutral position shown, movement of control member 25 to the left effects movement of member 32 to the left through the stud 27 engaging the cage 31 whilst movement of member 25 to the right also moves member 32 to the left through the stud 35 engaging cage 31. Reverse movements of member 25 effect corresponding reverse movements of member 32 through the locking action of ball 29 with notch 28 or 36. Figs. 4 and 5 show a similar device but adapted for transmitting rotary. motion from a control lever 52 to an actuated lever 53. A gear sector 39 connected to the lever 52 is geared through pinions 50, 51 to drive an auxiliary sector 41 in the opposite direction. The sectors 39 and 41 are provided with notches 44 and 48, for receiving the locking ball 45 carried by cage 40 connected to the lever 53, and studs 43, 47 for engaging the cage 40. Rotary motion of the control lever 52 in either direction from the neutral position shown effects a rotary movement of the lever 53 in the same direction. In another arrangement the gear sectors are arranged side by side each co-operating with a locking ball and both.of the latter co-operating with a notch in a fixed casing. The various notches and studs are so arranged that an idle period in which the actuated member is locked stationary is provided between its opposite movements. The Specification as open to inspection under Sect. 91 comprises also linear and rotary control linkages in which motion is transmitted from a control member to an actuated member over a part of the stroke of the control member only without reversal of the movement of the actuated member. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to Electrostatic Coating
Inventor: CHEMELAR ALOIS
IPC: B05B5/10
Filed: 1967-02-23
Abstract: 1,184,743. Electrostatic flocking. VELVETEX INDUSTRIAL CORP. 23 Feb., 1967, No. 8668/67. Heading B6G. Objects, e.g. walls, are electrostatically coated with fibres by providing an electrical potential across a pair of output terminals of an electrical potential power supply, electrically connecting one of the terminals to an electrode, establishing an electrostatic field directly between the object and the electrode by disposing the electrode closely adjacent the object without making any direct electrically conductive connection between the object and the other of the output terminals either through an electrical conductor or through a highly electrically conductive earth connection and the object and supplying loose fibres in the vicinity of the field. The wall may be coated with an adhesive made conductive by dispersing finely divided metallic particles therethrough. In Fig. 2 an applicator 18 comprises a housing 36 having closed top and bottom walls. The front side of the housing is open to form an outlet 38 through which fibres 12 pass when they are acted on by the electrostatic field between the grid-type electrode 28 and the wall surface 14. The outlet 38 is closed by a removable flat screen 40 which is slidable in a guide formed by a pair of spaced lateral flanges 42, 44. The electrode 28 is mounted on one end of a tubular support 46 which extends through a suitable aperture 48 in the bottom of the housing and serves as a handle 50. Alternatively, the support may be telescopically mounted on the housing so that the electrode 28 can be adjusted relative to the outlet 38. Housing 36, the screen 40 and the support 46 are all formed of insulating material. The electrode 28 is connected by a lead 30 to the negative terminal of a power supply, the other terminal of the power supply being connected to the chassis of the power supply. A circuit diagram of the power supply which comprises a conventional voltage multiplier is illustrated in Fig. 4 (not shown). Loose fibres are placed in the housing 36 and the outlet 38 is closed by moving the screen 40 to its lower limit. The individual fibres are oriented by the electrostatic field so that their longitudinal axes are perpendicular to the surface being coated. The fibres may be first treated to improve their conductivity, e.g. rayon fibres may be treated with a salt solution, nylon fibres may be treated with acetic acid. In an embodiment a wall was coated with an adhesive comprising alkyd resin and aluminium particles, and coated with conductive rayon fibres using the applicator. The power supply had a 500-watt input and an open-circuit output voltage of 40,000 volts.

Title: Improvements in fluid flow control valves
IPC: F16K11/056
Filed: 1965-03-01
Abstract: 1,085,546. Valves. RANDOLPH MFG. CO. March 1, 1965 [March 4, 1964], No. 8699/65. Heading F2V. A rotary selector valve comprises a cylindrical housing 11 (Figs. 3 and 4) having four inlet ports 20-23 and an outlet port 28, the inlet ports being normally closed by balls 25 under the action of spring 26. A crank-shaft 32 is journalled in the housing and carries a crank 38 having a crank-pin 39 on which is rotatably mounted a cam-plate 44 having four lobes 51-54. In the position shown, lobe 51 is received in the outlet port 28 and lobe 52 has unseated ball 25 from port 19, thereby allowing flow between these two ports. On clockwise rotation of the crank-shaft, the cam 44 rotates anti-clockwise and lobe 53 begins to unseat the ball from port 20 as lobe 52 begins to allow the ball to obturate port 19. Further rotation causes port 20 to be fully opened and port 19 to be completely obturated, the crank 38 at this stage being aligned with the radial axis at port 20. Continued rotation of the crankshaft successively opens the inlet ports. When the crank is aligned with the outlet port, none of the inlet ports will be open. When it is required that the ports extend only over a portion of the circumference of the housing, dummy openings may be provided, alternatively the arrangement shown in Figs. 7 and 8 may be adopted. In this latter embodiment, four inlet ports extend over an arc of 90 degrees and the outlet 70 is provided in the bottom of the housing, the inlet ports being in two axially spaced groups as shown. The cam in this case comprises two axially spaced lobed plates 93, 94, the upper, 93, having lobes 100, 101 for actuating the valves in the upper pair of inlets, and the lower, 94, having lobes 102, 103 for actuating the valves in the lower pair of inlets. When the crank is rotated through 30 degrees from the position shown, lobe 100 is released from port 69 and lobe 102 rotates to unseat the valve in the inlet adjacent but axially spaced from that previously opened by lobe 100. Continued rotation allows lobes 101, 103 to open successively the other two inlets. In both embodiments detents are provided to engage indentations in the housing cap. The valve balls may be replaced by axially guided discs or cones.

Title: A process for improving the odour of sulphuric acid ester salts
IPC: C07C303/44
Filed: 1953-03-30
Abstract: The odour of aqueous solutions of surface-active sulphuric acid ester salts obtained by sulphating higher alkenes is improved by a continuous multistage extraction in counterflow with a gasoline fraction boiling below 95 DEG  C. in the presence of a water-soluble alcohol having not more than four carbon atoms in the molecule, the extract being distilled to a temperature not exceeding 95 DEG  C. to recover the gasoline extractant for recycling.  The crude aqueous ester salts solution may be previously refined by continuous extraction, if desired after removal of inorganic sulphate, in counterflow with a low-boiling hydrocarbon (boiling range 80 DEG  to 130 DEG  C.) in the presence of a water-soluble alcohol having not more than four carbon atoms per molecule.  A gasoline boiling between 80 DEG  and 130 DEG  C. is suitable.  The gasoline and alcohol are distilled from the extract and recycled.  The volume ratio of extracting agent to ester salts solution is preferably about 1 to 1. The odour may be further improved by treating the ester salts solution with an adsorbent at temperatures between 20 DEG  and 80 DEG C. before or after the multistage extraction.  Suitable adsorbents are active carbon, activated bleaching earths, colloidal clays, polyvinyl resins and rubber powder.  After the extraction, the ester salts solution is heated in one or more equally-loaded evaporators at temperatures of 80 DEG  to 95 DEG  C. until the gasoline and alcohol have been removed.  To avoid decomposition, the evaporation should take place uniformly and should not be unduly prolonged.  In an example, an aqueous sodium alkyl sulphate obtained by sulphating a C8-C18 alkene fraction of a paraffin wax distillate was desalted by adding isopropanol and partially refined by counter-flow extraction with 80-130 DEG  C. gasoline at 45 DEG  C.  The extract was distilled and the gasoline recycled.  The raffinate was distilled to remove gasoline, leaving some isopropanol.  A minor proportion was further distilled to remove the isopropanol and diluted to a content of 21 per cent active substance for use as a solution of standard odour. The remaining raffinate was subjected to continuous counter-flow extraction in three stages with 70 DEG  to 95 DEG  C. gasoline.  This raffinate was concentrated in four evaporators for four hours at 90 DEG  C.  Specifications 407,990 and 480,904 are referred to.

Title: Manufacture of polymeric materials
IPC: C07C57/03
Filed: 1940-05-17
Abstract: 542,642. Esters ; synthetic resins. DU PONT DE NEMOURS & CO., E. I., and RICHTER, H. J. May 17, 1940, No. 8835. [Class 2 (iii)] Alkylidene esters of α-methylene monocarboxylic acids are made by re-acting an aldehyde with an anhydride of an α-methylene monocarboxylic acid in the presence of a condensing agent, e.g. ferric chloride or concentrated sulphuric acid. The anhydride may be of the general formula (CH 2 =CR-CO) 2 O, where R is hydrogen or an alkyl or aryl group or a halogen atom, and the aldehyde may be of the formula R<SP>1</SP>CHO, where R<SP>1</SP> is hydrogen, or an aryl, aralkyl or alkenyl group. When sulphuric acid is used as the condensing agent, a polymerization inhibitor, e.g. cupious chloride, is preferably added. In examples, methacrylic anhydride is condensed with acetaldehyde, formaldehyde, heptaldehyde, and acrolein. Other specified anhydrides are acrylic, α-butylacrylic, α-phenylacrylic and α-chloracrylic anhydrides. The following aldehydes also are specified : butyraldehyde, valeraldehyde, benzaldehyde, o-toluylaldehyde, phenylacetaldehyde, cinnamic aldehyde, and crotonaldehyde. The products can be polymerized by heat, with or without the addition of catalysts, to form clear, hard water-insoluble resins. They may also be interpolymerized with other substances, especially with compounds of the formula: where R is an organic radicle containing a carbon atom joined to a second carbon atom by more than one bond, the multibonded atom being separated from the CH 2  =C< group by not more than one chain atom. Examples of such compounds are acrylic and methacrylic esters, methacrylic nitrile, vinyl acetate, methylvinyl ketone, butadiene, chloroprene and styrene. Examples are given of the polymerization of ethylidene dimethacrylate, and of its interpolimerization with methyl methacrylate, vinyl acetate, and methyl acrylate, and of the interpolymerization of methylene dimethacrylate and methyl methacrylate, and of butylidene dimethacrylate and methyl methacrylate.

Title: Cracking heavy hydrocarbon oils by means of a fluidized bed of hot inert-solid particles
IPC: C10G9/32
Filed: 1956-03-21
Abstract: In a process for cracking heavy hydrocarbon oils, such as residual oils, by introducing the oil into a fluidized bed of hot inert-solid particles, the product-vapours issuing from the reactor are scrubbed with a heavy hydrocarbon oil in order to remove entrained solid particles and those oil components boiling above 1000 DEG  F., the vapours are then scrubbed with a lighter <PICT:0815155/III/1> hydrocarbon oil to remove heavy gas oil having an initial boiling point within the range 800-950 DEG  F., and the scrubbed vapours are fractionated whereby gas oil, suitable for catalytic cracking, is obtained.  The liquid withdrawn from the first scrubbing zone is introduced into the fluidized bed.  The liquid withdrawn from the second scrubbing zone is partially vaporized to remove lighter gas oil components, and the liquid-residue is recycled to the fluidized bed.  In an example, a residual oil having an initial boiling point of 1000 DEG  C. is injected through manifold 2 into a fluidized bed of coke particles maintained at a temperature of 950 DEG  F., whereby 75 per cent of the feed is converted to products boiling below 1000 DEG  F., and coke is deposited on the particles.  The vapours pass through cyclone 8; and are introduced into the lower section of scrubbing tower 10, where they are contacted with a recycle bottoms fraction, having an initial boiling point of 1075 DEG  F. and an inlet temperature of 600 DEG  F., supplied through line 11 in an amount sufficient to condense all material boiling above 1030 DEG  F. The scrubbing liquid and the condensate collects in the base of tower 10; a portion of this liquid is recycled via heat-exchanger 13 to line 11, and the remainder is introduced via line 16 into the lower part of the fluidized bed.  The vapours leave the first scrubbing zone through plate 17, and are then scrubbed with recycled heavy gas oil, boiling within the range 800-950 DEG  F. and having an inlet temperature of 500 DEG  F., supplied through line 18 in amount sufficient to condense all material boiling above 950 DEG  F.  The liquid which collects on plate 17 is in part recycled via heatexchanger 21 to line 18, while the remainder is passed through line 20 to the uppermost portion of the fluidized bed where gas oil is vaporized with substantially no cracking and the heavier components are deposited on the particles.  Alternatively, the liquid in line 20 may be passed to an external vaporization zone, such as a fluidized bed or a transfer line zone where it is contacted with solid particles at a temperature of 600-800 DEG  F. The vapours can then be returned directly to the second scrubbing zone, while the particles, charged with liquid deposit, are passed to the cracking reactor.  In another alternative, the feed oil is subjected to initial topping to remove gas oil in a vacuum tower; and the liquid withdrawn from the second scrubbing zone is also passed to the vacuum tower.
