Title: Improvements in fuel injection pumps
IPC: F02M59/44
Filed: 1968-06-11
Abstract: 1,208,635. Fuel injection pumps. ROBERT BOSCH G.m.b.H. June 11, 1968 [June 16, 1967], No.27625/68. Heading F1A. In a fuel injection pump of the type in which a control edge on the piston surface uncovers a spill-port to regulate delivery the cylinder wall has relief groove 10 and the piston surface has annular fuel-collecting grooves 13, 14 connected by a spiral groove 15. At the end of the injection stroke, the fuel-collecting groove 13 overlaps the relief groove 10 and pressurized fuel-flow from spill-port 7 and a channel 11, into the fuel-collecting groove 14. In the embodiment shown, at the end of the suction stroke, the fuel-collecting groove 14 emerges from the cylinder and the consequent relief forces any injurious residues and old fuel out of the end of the piston to be wiped off on the next injection stroke. When the pump is to be used with highly purified fuels, the groove 14 need not be arranged to emerge from the cylinder at the end of the suction stroke, Fig. 2 (not shown).

Title: Recovery of polycarbonates
IPC: B29C48/50
Filed: 1961-08-01
Abstract: <PICT:0924756/IV(a)/1> Solid polycarbonate is recovered from its solution in an inert organic solvent by heating the solution to volatilize solvent therefrom and to raise it to a temperature at which the polycarbonate is flowable while maintaining superatmospheric pressure upon the solution so as to retain with the polycarbonate sufficient solvent to keep the polycarbonate-solvent mixture liquid until attaining a temperature at which the polycarbonate is flowable, and thereafter extruding the substantially solvent-free polycarbonate.  The solution to be treated is preferably that obtained by phosgenation of an organic dihydric compound in an aqueous alkaline medium containing the organic solvent.  The dihydric compound is preferably a bis-phenol but may also be another dihydric phenol, a dihydric alcohol or a mixture of various dihydric compounds.  The organic solvent may be chloroform, methyl chloride methylene chloride, ethylene chloride, beta, beta1-dichloroethyl ether, acetylene dichloride, dichloroethylene, a dichlorobutane, benzene, xylene, 1:4-dioxane, acetone, isobutylketone or tetrahydrofurane.  In an example, a methylene chloride solution of bisphenol A polycarbonate is fed via an inlet port 3 (where it is preheated to 82 DEG C.) into an extruder comprising a barrel 1 having cylindrical bores 10 and 11 and surrounded by a heating bath 2.  In the bores are worm flights 6 and 7 interrupted by pressure blocks 8 and 9 which divide the apparatus into three zones, A (maintained at 215 DEG C.), B (maintained at 283 DEG C. and 140 p.s.i.g.) and C (maintained at 23-34 mm. of Mg. pressure).  In zone A the solution is further heated and in zone B most of the methylene chloride is vapourized and is removed through a port 4.  In zone C, the remainder of the methylene chloride and other low boiling substances are vapourized and removed through a port 5.  Finally, the polycarbonate is extruded through a die 13 at 288 DEG C. into strands which are air-cooled on a perforated surface and then cut up into pellets.

Title: Improvements in weft-detecting mechanism for looms for weaving
IPC: D03D51/34
Filed: 1926-11-08
Abstract: 271,735. Hollingworth, E., (Crompton & Knowles Loom Works). Nov. 8, 1926. Weft-feeler arrangements. - The detecting element is mounted on a structure which is moved, on detecting beats of the loom, towards the surface to be detected and then has its motion arrested, the inertia of the detecting element and, or, its mounting acting to carry the detector further forward to perform its detecting function. As shown, a side-swipe feeler 24 is pivoted at 25 to a lever 26 which is pivoted at 27 to the transferrer arm 11. An adjustable tension spring 31 tends to turn the lever 24 in a clockwise direction, the motion being limited by a screw 29 engaging a projection 28 on the lever 26. The arm 26 is normally held in the raised position by a spring 40 secured to a screw 41 on the arm and to an adjusting screw 41 in a lug 43 on the transferrer. In operation, the transferrer moves quickly towards the bobbin and has its motion arrested, the inertia of the parts 24, 26 causing the detector 24 to engage the weft. An extension 45 of the lever 26 engages the spring 40 and puts it under additional strain whereby the detector is moved back quickly when the inertia of the parts is spent. When the weft is substantially exhausted, the detector 24 slips into the position shown and engages an arm 23 of a spring-- controlled latch 21 which normally engages the head 17 of a spring-controlled plunger 12. The plunger is thereby freed and moves to the right to cause weft replenishment or stoppage of the loom. To cause the detector to strike the yarn the same blow at all times, the tension of the spring 40 is adjusted in accordance with the speed of the loom.

Title: Cigar pressing machine
IPC: A24C1/44
Filed: 1970-06-09
Abstract: 1,239,889. Cigar-pressing machines; piercing cigars. AMERICAN BRANDS Inc. 9 June, 1970 [18 June, 1969], No. 27990/70. Heading A2C. In an apparatus for pressing cigars, the cigars are carried by a conveyer 10 past a sensing means 18 forming part of a counting means that, when it has counted a predetermined number of cigars passing into a selecting station, causes a bar actuator 17 to move the said number of cigars as a batch in their axial direction into a press 20 where they are first compressed laterally by press rods 27 and immediately thereafter pressed by upper and lower platens 25, 25<SP>1</SP>. As the platens 25, 25<SP>1</SP>, which include electrical heating pads 26, 26<SP>1</SP>, are lowered by the press 20 they are initially kept spaced a distance somewhat greater than the height of the cigars by springs 35, 36, while rollers 29, 29<SP>1</SP> carried by the press rods 27, 27<SP>1</SP> urge the latter inwardly as the former travel down inclined sections of channels formed by rods 30, 31 and 32, 33. Finally, as the lower platen reaches the bottom of the press 20 the upper platen 25 completes its downward movement against the action of the springs 35, 36 to compress the cigars to an extent determined by the thickness of the press rods 27, 27<SP>1</SP>. The batch of heated and pressed cigars is then transferred to the top of an accumulator 39, in which they are stacked several rows high and where they are cooled and dried to set them by a cool air flow, and simultaneously the batch in the lowermost row in the accumulator 39 is removed by a bar actuator 47 and forwarded by a conveyer to a packing station. The bar actuator 38 may include a plurality of piercing means 46a, 46b &c. for piercing the tips of the cigars as they are transferred to the accumulator 39.

Title: An improved process for the production of finely divided silica
IPC: C08K3/36
Filed: 1951-11-29
Abstract: <PICT:0710015/III/1> Finely divided non-gelatinous silica is produced by reacting an alkali metal silicate with a hydrogen ion donor in the presence of an indifferent electrolyte, e.g. an alkali metal salt of a strong acid, wherein a solution or slurry of the silicate and a solution of the hydrogen ion donor, which latter may contain some of the indifferent electrolyte, are introduced simultaneously but separately into a solution containing at least 1 per cent. by weight of the indifferent electrolyte which is stirred in a reaction vessel, the concentration and quantity of the silicate and acid solutions introduced being such that in the reaction vessel the sum of the concentrations of the alkali metal salt formed and of the indifferent electrolyte, including any of the latter introduced with the acid, is at all times throughout the reaction greater than 1 per cent. of the solution in the reaction vessel.  The preferred concentration in the reaction vessel is 5-10 per cent.  Preferred electrolytes are sodium chloride or sulphate, although alkali metal carbonates, which are not attacked in the presence of the silicate may also be used.  Hydrogen donors are acids, e.g. hydrochloric or sulphuric, acid salts, e.g. sodium bisulphate, or ammonium salts, particularly of strong acids, e.g. ammonium chloride, in which latter case the ammonia formed may be collected.  Preferably the electrolyte is the same salt as is formed during the reaction, so that the resulting solution, after silica separation, may be used as the electrolyte in subsequent reactions, after adjustment of concentration, if necessary. 6-25 per cent. sodium silicate solution from tank Z1 passes through pipe L1 to the bottom of vessel A, which contains the electrolyte solution, while 1/2 -5N acid from tank Z2 is fed on to centrifugal disc S, so that the acid is added at a point as far removed as possible from the silicate and in fine subdivision, while the electrolyte solution is stirred. In an alternative apparatus (not shown) for continuous operation an outlet is provided near the mid-point of vessel A, and the silica containing solution is withdrawn therethrough, at a rate equivalent to the rate of addition of the reactants to a washing vessel wherein the silica is washed with acid, before it is separated on a filter or centrifuge.  The pH of the precipitating zone may be adjusted to say 8.5 by controlling the rates of addition of the reactants.
