Title: Method for the air-tight packing of powdered, granular, finely-divided or paste-like material
IPC: B65B9/093
Filed: 1952-12-16
Abstract: 721,580. Filling bags. INDUSTRIEWERKE KARLSRUHE AKT.-GES. Dec. 16, 1952 [Dec. 24, 1951; Jan. 31, 1952], No. 31813/52. Class 94 (1). A method of air-tight packing of powdered, granular or paste-like material in bags in which successive pockets are formed in a V-shaped band by glueing, heat sealing &c. separating the pockets to form separate bags which are opened, filled and closed at their filling ends is characterized in that the filling and closing process takes place on an intermittently operated turn-table which has pairs of tongs at its circumference which grip the bags. The bags are opened by moving the tongs of each pair towards one another with the simultaneous insertion of a shaping piece, and the tongs guide the opened bags to filling and closing devices and to a delivery member. The band 2 is fed from a roll 1, folded into a V-shape 3 and passed between rollers 4, and when stationary is sealed by jaws 5, 6 to form a series of pockets. An intermittently operated pair of rollers 7 feed the band to cutters 8, and the separated bags 9 are fed by reciprocating tongs 10 to pairs of tongs 12 on a turntable 11. The tongs 12 of each pair move together and a shaping piece 13 is inserted into the bag mouth. The bags are filled at 14, the tongs 12 recede to close the bag mouth which is sealed at 16, and the bags are then fed to a conveyer 18. To ensure that the shaping piece may readily enter the bag a thin strip is arranged near the tongs 10, and is pushed into the open side of each bag, during its delivery to the tongs 12.

Title: Method of producing laminated sheet materials
Inventor: SHRIMPTON RONALD HORACE
IPC: D06N3/14
Filed: 1957-10-12
Abstract: 893,637. Polyurethane coatings. DUNLOP RUBBER CO. Ltd. Sept. 9, 1958 [Oct. 12, 1957], No. 31933/57. Class 140. A laminated sheet material is produced by casting on a non-metallic backing sheet a layer of a liquid polyurethane intermediate product, said intermediate product being a reaction product of a polymer containing terminal hydroxy groups and an aromatic polyisocyanate having a cross-linking agent incorporated therein, and completing the polymerization of the intermediate product in situ. The polyurethane intermediate product may be prepared by heating a polymer containing terminal hydroxy groups, such as a polyester, e.g. polyethylene adipate or sebacate, polyether, e.g. polyethylene glycol, or polyesteramide, with an aromatic polyisocyanate, to form a syrup and immediately prior to casting stirring a crosslinking agent therein. Alternatively, the intermediate product may be prepared by reacting the polymer containing terminal hydroxy groups with a slight excess of polyisocyanate and then with a further quantity of the polymer to form the syrup into which the cross-linking agent is subsequently stirred. The crosslinking agent may be water, a glycol, e.g. butylene 1,4-glycol or propylene glycol, or an amine, e.g. ethylene diamine or triethylamine. The backing sheet may be a sheet of fibrous material such as leather, e.g. chrome leather, leather-board, paper, and textile materials including cotton duck, canvas and like woven fabrics such as an open-weave nylon monofil fabric, or a sheet of non-fibrous material such as natural or synthetic rubber. It is preferable that the surface of the sheets of non-fibrous material be provided with a layer of adhesive prior to casting the polyurethane intermediate product thereon. The adhesive may be based on polyurethane which may comprise a reaction product of a polyester and an aromatic diisocyanate to which an aromatic triisocyanate is added, or the reaction product of trimethylol propane and toluene diisocyanate. Examples of polyisocyanates are toluene and naphthalene diisocyanates, and triphenylmethane triisocyanate. Pigments, colouring materials, fillers, plasticizers, and modifiers may be added to the intermediate product, preferably prior to the addition of the cross-linking agent. The backing sheet may be held on a heated vacuum mould during the casting operation. The intermediate product may be allowed to set in the mould, the laminated sheet removed from the mould and polymerization completed by heating. Fabric or paper may be stretched in a framework and/or held on a hot plate, during the casting operation. It may be desirable to store the laminated material in a curved position to counteract shrinkage of the polyurethane coating.

Title: Means for the opening and closing of angularly movable panels
IPC: E05F11/06
Filed: 1974-07-18
Abstract: 1484726 Operating mechanisms for angularly movable panels TELEFLEX MORSE Ltd 10 July 1975 [18 July 1974 7 March 1975] 31961/74 and 9675/75 Heading E2M A mechanism for moving panels mounted for angular movement (in particular top and bottom hung windows) comprises: a chaincase 1 for mounting with respect to a fixed frame and containing a sprocket 19 and a stored drive chain 2 which connects to the panel, a drive box 4, which is secured to the inside of the frame and which releasably receives the chaincase, containing a wheel 25 driven by a cable 34 and connected to drive, directly (as shown) or indirectly via gearing, the sprocket 19; the chaincase 1 being mountable on the drive box 4 in four different positions: as shown in Fig. 9 for a top hung panel, extending to the other side to allow cable 34 to enter from the right (Fig. 8 not shown), and extending to either side in an upside down position for use with bottom hung panels (Figs. 10, 11 not shown). The cable 34 has a helically wound inner 32 which engages teeth on wheel 25 to turn member 21 connected to sprocket 19 via coupling member 29 which engages grooves in each member to allow incremental adjustment to be made between them before they are locked together. The member 21 can engage in either open end of the sprocket. Bolts pass through holes HI, H2 in the chaincase and through one of alternate sets A1, A2, B1, B2, Cl, C2, Dl, D2 in the drive box 4 (Fig. 7), and the drive box is bored to allow the cable 34 to enter from either side. The chaincase shown is formed of upper and lower die-cast sections 5, 6 and an extruded aluminium portion 9 which receives the coiled chain. As previously stated the components can be mounted so that section 9 extends to the left or the chaincase can be turned upside down in either position of the section 9 so that chain 2 issues from the opposite side of the chaincase. In another embodiment (Figs. 12-18, not shown) section 9 is integral with the rest of the chaincase and the whole is closed by a flat upper plate-more coils of chain being accommodated. The holes H1 and H2 are equidistant from the centre of sprocket 19 and arranged so that only two holes in the drive box are needed to align with the holes H1, H2 in all four positions. The cable 34 can be connected to a manual or electric drive.

Patent GB-756462-A (GB)
Title: Improvements in or relating to process for refining sour petroleum distillates
Inventor: KRAUSE JACK H
IPC: C10G17/06
Filed: 1953-11-20
Abstract: Sour straight-run petroleum distillate boiling within the range between about 300 DEG  and 650 DEG F. is refined by contact with sulphuric acid in two stages, the refined product being substantially neutral and substantially sweet and producing an amount of steel dish deposit, when employing a specified procedure, not greater than 10 milligrams.  In the first stage, the distillate is contacted at a temperature beween about 145 DEG  and 175 DEG F. with an amount of fresh sulphuric acid, having a concentration between about 90 and 100 weight per cent, sufficient to substantially sweeten the distillate. After separating the distillate from acid and acid sludge, the distillate is contacted in the second stage at a temperature between about 90 DEG  and 130 DEG F. with an amount of fresh sulphuric acid, having a concentration between about 90 and 100 weight per cent, sufficient to remove oil-soluble products formed in the first stage. Finally, the distillate is freed of acid, acid sludge, pepper sludge and other occluded materials to obtain the refined product.  The temperatures employed in the two stages are related to each other, so that the higher the temperature of operation in the first stage, the lower the temperature of operation must be in the second stage.  The petroleum distillate may be an illuminating oil, burning oil, furnace oil, heater oil, diesel fuel or jet plane fuel.  The fresh sulphuric acid may be commercial grade sulphuric acid or may be "black sulphuric acid" obtained by the regeneration or decomposition of acid sludge.  The pepper sludge and other occluded materials may be removed by passing the distillate through a coalescer packed, for example, with steel wool, metal chain, carbon Raschig rings, or Berl saddles, or by washing the distillate with water.  The refined product may be neutralized by washing with dilute aqueous caustic soda solution, by contact with fuller's earth, Attapulgus clay or acid-treated clay, or by passage through a bed of basic materials such as magnesium carbonate or hydroxide.  The neutralized distillate, if desired after water washing, may then be dehydrated by passage through a vessel packed with coarse rock salt, or by passage through a coalescer packed with excelsior, fibre glass or steel wool. Apparatus for carrying out the process of the invention is described. The effect of treating a petroleum distillate boiling between 330 and 544 DEG F. with 98 per cent sulphuric acid at 90-150 DEG F. in the first stage and 90-140 DEG F. in the second stage is described, and also the effect of using acid sludge instead of fresh sulphuric acid in the first stage.

Title: Improvements in or relating to triggered pulse and sawtooth waveform generators
Inventor: FENTON ROGER WAKEFIELD
IPC: H03K4/84
Filed: 1962-08-22
Abstract: 983,017. Transistor pulse and sawtooth circuits. MARCONI CO. Ltd. June 12, 1963 [Aug. 22, 1962], No. 32291/62. Addition to 972,250. Heading H3T. The pulse or sawtooth generator described in the parent Specification is improved so as to use shorter duration trigger pulses or to obtain larger amplitude output pulses. As shown in Fig. 4, a triggered pulse or sawtooth generator comprises a transistor 4 and a unijunction transistor 1, both normally conductive so as to maintain a low voltage across capacitor 3. When a short-duration positive trigger pulse is received at terminal A, transistor 4 becomes nonconductive, turning off transistor 1 and allowing capacitor 3 to charge linearly via the leakage resistance of transistor 4 and diode 14 until the triggering voltage of unijunction transistor 1 is reached, when both transistors become conductive, discharging capacitor 3 via diode 13 and restoring the circuit to its stable state. The forward threshold voltage of diode 13 is made greater than the unijunction transistor backlash current so that the capacitor 3 is rapidly isolated from the unijunction transistor 1 during triggering and hence allows short-duration triggering pulses to control circuits of long time constant. In Fig. 6, an additional transistor 15 of the NPN type is included, the circuit being triggered by a triggered or self-oscillating unijunction transistor 18. Higher voltage pulses are available at 17. Alternatively as in Fig. 5 (not shown) the circuit may be triggered by positive pulses fed to the base of transistor 4 or negative pulses fed to the base of transistor 15.

Title: Improvements in or relating to apparatus for testing springs
IPC: G01N3/00
Filed: 1945-11-30
Abstract: 615,445. Testing springs for rating and free length. IGRANIC ELECTRIC CO., Ltd., and RANDALL, C. E. Nov. 30, 1945, No. 32403. [Class 106 (ii)] Apparatus for testing the rating of springs comprises means for applying a given load increment to the spring to be tested, and an optical lever for indicating the change in length of the spring consequent upon the application of the load. The apparatus is also adapted for checking the free lengths of springs. As shown, a tension spring 1 to be tested is attached at one end to an adjustable peg 2 and at the other end to a hook 3 on one end of a beam 4, the latter having a central knife edge 5 resting on a support 6 and carrying a weighted arm 11 at the other end. The support 6 rests on a member 7 (not shown) having a cam face, horizontal movement of the member 7 moving the support 6 vertically in slides 34 so that the beam 4 is raised to pick up the weighted arm 11 and stretch the spring 1. An optical projector 13 (not shown) projects the image 15 of a fine wire upwardly on to a fixed mirror which reflects it on to a mirror 12, mounted on the beam 4, from which it is reflected by the aid of three other fixed mirrors on to a screen 14. In operation, with the beam 4 in the lower unloaded position, the spring is attached and the peg 2 adjusted until the image 15 coincides with the zero mark 20 on the screen, the beam is raised to pick up the load and stretch the spring, and the elongation of the spring is indicated by the position of the image 15 on the screen 14. The arm 11 carries removable weights 8, and the beam 4 has a small weight 23 mounted for adjustment on a screw. For checking free lengths of springs, a standard spring is attached, the peg 2 adjusted so that the image 15 is at zero point, and the spring to be checked is then substituted. The difference in length can be read on a scale 24 on the screen, or by the degree of rotation of a fine adjustment device 27 for the peg 2. The peg 2 is on a slide 28 clamped by a screw 30 to a vertical rod 29 having screw-threaded engagement with the device 27. In a modification of the device 27 the latter is mounted on a circular base having a circular T-shaped groove to receive stop elements co-operating with a pointer on a radial arm which can be clamped to the device 27. Compression springs can be tested for length and compression between a cone 3a on the beam 4 and a cone 2a adjustable along the rod 29.
