Title: Fuel injection systems for internal combustion engines
Inventor: WALLIS KENNETH BASIL
IPC: F02M51/00
Filed: 1962-06-07
Abstract: 1,038,541. Regulating I.C. engines; electromagnetic valves. ASSOCIATED ENGINEERING Ltd. May 28, 1963 [June 7, 1962], No. 22135/62. Heading FIB. [Also in Division 61] The period during which a fuel injection valve 4 in an internal combustion engine is open is determined by the duration of electrical pulses produced by a control circuit 8 fed with at least one variable voltage which varies with variations in parameters of the engine operation. Trigger pulses from the distributer are differentiated and applied directly to the control pulse generator 21 to initiate each output pulse. The duration of each output pulse is determined by a voltage from computer 10 responsive to barometric pressure, ambient temperature, water temperature, manifold pressure, throttle position, idling, and acceleration. The pulse duration is also controlled in accordance with engine speed by means of an auxiliary pulse generator 22 and discriminator 23. Fixed length pulses are simultaneously initiated at 24 and after amplification are added to the amplified pulses from generator 21, so that a stepped pulse is passed by distributer 9 to valves 4. The initial large amplitude ensures immediate opening of the valves, and the subsequent lower value ensures rapid closure. In a modification the pulses supplied to discriminator 23 are derived from control pulse generator 21, and generator 22 is omitted. The acceleration responsive transducer may be replaced by a differentiating circuit producing a signal which is the first derivative of the manifold pressure. In computer 10 basic control is by a potentiometer whose slider is moved in dependence upon the manifold pressure and which is connected across a stabilized voltage supply. Connected in series with this potentiometer are further potentiometers and thermistors responsive to the remaining engine parameters. Distributer and contact breaker (Fig. 9a to 9d, not shown). Cam 42 operates make-and-break contacts 43 and carries a metal cup-shaped member 44 having an isolated segment 45 which makes contact with centre brush 46 and one radial brush 47. Injection valve (Figs. 10 and 11). In one embodiment solenoid coil 71 has a hollow core 74. Armature 72 is normally urged upwards by springs 75, 76, so holding pintle needle 78 up to close valve 79. Energization of coil 71 draws armature 72 downwards to open the valve. Centre member 77 is free to deflect under the fuel pressure and the assembly works as a normal pintle nozzle. In another arrangement (Fig. 11, not shown) a nylon seal 80 is normally pressed against a seating 81 by a spring 56, and is lifted by an armature 60 when solenoid 51 is energized. Fuel then flows to convergent nozzles 82 and is atomized in chamber 83. The trigger pulses may be derived directly from the contact breaker, or through capacitive or inductive couplings, or from an electrooptical arrangement on the distributer or engine flywheel.

Filed: 1935-08-06
Abstract: <PICT:0460973/III/1> Sulphuric acid is recovered from acid sludge &c., obtained in the refining of mineral oils with concentrated or fuming sulphuric acid by mechanically emulsifying the sludge &c. at a temperature of about 30--210 DEG  C., and preferably under pressure, with about 20--50 per cent of water without the addition of alkali and separating the emulsion formed into two layers consisting of aqueous sulphuric acid and tar by allowing it to stand under pressure, separating the two layers from one another, recovering the sulphuric acid from one layer by evaporation of the water and decomposing the tar layer by distillation or cracking.  Increased pressures up to 20 atmospheres and temperatures up to 210 DEG  C., may be employed in breaking down the emulsion.  Acid sludge and water are fed into a heated emulsifying vessel 1 provided with a stirrer 2 and preferably provided with an oil-filled jacket.  The emulsion is taken through a pipe 5 into settlement vessels 9, 10 and 11 in which it is allowed to stand under pressure.  After separation, the impure sulphuric acid passes through a pipe 15 into a vessel 16 while the tar is drawn off through sluices 17, 18 and 19 or suction pipes 20, 21 and 22 into a vessel 25.  The settlement vessels may be heated. The deacidified tar is fed from the vessel 25 either to a distillation vessel 27 or into the retort 28 of a cracking furnace. The acid is fed from the tank 16 into a pipe system 32 located in the lining of the retort.  Water is evaporated and steam escapes through outlets provided. Purification vessels 33 containing glass wool or the like are interposed in the pipe 32.

Abstract: 1,199,222. Assembling coils in stators. INDUSTRA PRODUCTS Inc. 10 May, 1968, No. 22250/68. Heading B3A. A process for inserting prewound coils into stator and like slots comprises passing an ironing member 32 into a slot 12 to effect compression of a first coil 14, simultaneously carrying a second coil 16 or 18 into position wherein it at least partially enters the slot longitudinally while the first coil is maintained at least under partial compression, and simultaneously covering the second coil with insulated wedges 20 to provide a compressed mass of superimposed coils. The apparatus 22 for performing the process is moved by a stripper 80 via a rod 33, the apparatus passing through the stator 10. The coils 16, 18 are placed between stationary fingers 48 and wedge guides 50, and the stator 10, with the coils 14, is positioned on top of the guides 50. The stripper 80 is then moved upwardly so that tapered faces 34 of the irons 32 enter the stator slots 12 to compress the coils 14 therein. The stripper engages the coils 16, 18 to push them along the fingers 48, down inclined faces 92 of the guides 50 and into the slots 12. Simultaneously, the stripper has been moving wedge pushers 60 so that their respective wedges 20 are just behind the irons 32. As the ends 40 of the irons clear the slots 12 the wedges are fully inserted therein and the apparatus 32 is lifted off the rod 33. The stator 10 is then removed and the end turns of the coils 16, 18 can be formed outwardly in any suitable manner.

Title: Improvements in or relating to floor covering materials and a method of and apparatus for decorating the same
IPC: D06N7/00
Filed: 1929-07-20
Abstract: 319,655. Armstrong Cork Co., (Assignees of McCarthy, J. C.). Sept. 25, 1928, [Convention date]. Resist printing. - Hard-surfaced covering materials, such as linoleum and felt-base floor covering, are decorated by applying a masking material to portions of the surface, applying a thick wear-resisting film thereover, and then removing the masking material and the portion of the wear-resisting film thereabove. The process is particularly applicable in applying rapidly drying paint such as nitro-cellulose lacquer. The masking material is preferably of non-drying nature, and is put on in the form of a design, and the whole surface is sprayed with the lacquer. The material is then scrubbed with water to remove the masking material. The material is drawn from a roll 2, Fig. 1, and passes beneath means such as sprayers 3 for applying either a plain or spotted colour over the entire surface of the material. This base coating may be omitted. The material then passes under printing mechanism 4, which may be of rotary or reciprocating block type, which applies the masking material in the form of a design, and the printing is preferably repeated to ensure a sufficient thickness. An all-over coating of lacquer is next applied by means of spraying- apparatus 5. The coating is then dried, preferably by means of cold water jets J, and the material then passes through a brushing and rinsing unit comprising brushes 2 and jets 7, 7<1>. After being scrubbed and rinsed, the material preferably passes over a rubber squeegee roll R co-operating with a roll R<1> around which the material passes during the scrubbing. The operations may be repeated by a similar series of mechanisms 8, 9, 10. An example of a pattern in three colours is shown in Fig. 2. An all-over base coat 11 is first applied, masking is then applied to the whole surface except the area 12, and lacquer of the colour to be applied to that area is sprayed over the whole surface. The material is then scrubbed, and the lacquer left only on the area 12. By a similar process, another colour is applied to the area 13. Fig. 7 shows a tile pattern in which the spotted appearance of the tiles is produced by means of sprayers adjusted so as to project drops of lacquer. Preferably, the scrubbing is effected before the lacquer is dry, so as to blur the outline. The masking material may consist of 60 parts of whiting or other filler, 40 parts of glycerine, and two or three parts of soap solution containing 24 parts of anhydrous soap and 76 parts of water. Ethylene. glycol may be used instead of glycerine.
Patent GB-1191124-A (GB)
Title: Method and Apparatus for Producing Flexible Tubing
IPC: B21C37/12
Filed: 1967-05-15
Abstract: 1,191,124. Making tubing; coiling; seaming; perforating. VULCAN AUSTRALIA Ltd. 15 May, 1967 [16 May, 1966], No. 22375/67. Headings B3A, B3E, B3J and B3W. [Also in Divisions B5 and F2] A method for the manufacture of flexible tubing comprises forming in a strip of ductile material a series of corrugations, feeding the strip to a mandrel, coiling the strip about the mandrel with adjacent edges of the convolutions of the strips overlapping one another and seam locking together the adjacent edges. Aluminium strip 51 is fed and longitudinally corrugated by pairs of rollers (35), 35a-(41), 41a the rollers being arranged to successively increase the number of corrugations formed in the strip. The rollers (41), 41a also form an edge flange 56, Fig. 13, and further rollers 42, 42a form a deep edge corrugation 57. The corrugated strip then passes to a coiling head 46 comprising, Fig. 5, 21, a mandrel 62 on which the strip is coiled by driven forming rollers 64, 65, 66 and 69, the strip being guided thereto by a roller 71 and plate 72. The mandrel 62 is freely rotatable on a shaft 83 which may be withdrawn axially with the mandrel by rack and pinion means 124, Fig. 22. The strip edge flange 56 nests with the deep edge corrugation 57 and a freely rotatable seaming roller 63, Figs. 5, 15, co-operates with the roller 64 to push the outer half of the seam over at an angle of 45 degrees. The strip is then guided by an edge plate 74 to the roller 65 which bends over the outer half of the seam a further 90 degrees, Fig. 17 (not shown). A seaming roller 67 co-operates with the roller 66 to complete the bending over to form a locked seam and a roller 68 and the roller 69 bend over and finally flatten the seam to form a double locked seam, Fig. 20 (not shown). The formed tube passes off the end of the mandrel 62 and is supported by idler rollers 48 and driven roller 47. After leaving the mandrel the rotating tubing moves past a backing roller 80, Fig. 21, mounted on the same shaft as the roller 65, and a spiking roller 81 located inside the tube and mounted on a cranked extension 82 of the mandrel shaft 83, rotation of the tubing causing rotating of the spiking roller 81 so that conical spikes 87 thereof project through the tubing into grooves on the roller 80. The extension 82 carrying the spiking roller 81 is adjustable to and from the tubing so that the size of the holes made may be varied by varying the extent to which the spikes perforate the tubing. This adjustment is effected by an eccentric 91 on a shaft 90 rotatable within the mandrel shaft 83 by crank means 136 operated by piston-and-cylinder means controlled by a timing plate 140, Fig. 1, carrying annular cams 143, 144, 145 operating valves 146, 147, 148. The arrangement is such that banded patterns of large holes, small holes and no holes are produced in the tubing. The perforated tubing is cut to length by a flying saw 110, the severed tubes being moved away from the tubing issuing from the mandrel by rotating the support roller 47 at an appropriate speed.
