Patent GB-359611-A (GB)
Title: Improvements relating to devices for injecting fuel into internal combustion engines
IPC: F02M59/02
Filed: 1930-08-11
Abstract: 359,611. Fuel-injection pumps. HESSELMAN, K. J. E., Saltsj÷ Storangen, Sweden. Aug. 11, 1930, No. 24060. Convention date, Sept. 9, 1929. [Class 102 (i).] In a fuel-injection pump, in which the injection is terminated by the opening of a byepass valve 11, blowing back of the combustion gases due to the slow closing of the pump dischargevalve is prevented by means of a second byepass valve 13. The latter is spring-loaded to a pressure equal to or greater than that in the combustion chamber, but less than that of the dischargevalve. The stem of the valve 11 may be formed with a passage 14, which, on further movement of the valve 11, shortcircuits the valve 13, thus allowing fall of pressure and escape of air. The valve 11 may be operated from the plunger cam 3 through a lever 21 having an eccentric mounting. Alternatively, the valve 11 may be in line with the plunger and opened by the plunger. Specifications 304,100 and 306,801, [both in Class 102 (i), Pumps &c.], are referred to.

Abstract: 696,561. Feeding webs. WINGFOOT CORPORATION. Feb. 20, 1950 [Oct. 22, 1949], No. 24223/51. Divided out of 696,546, [Group XVII]. Class 100(i) [Also in Groups XVII and XXX] In a wrapping-machine (see Group XVII) a web of heat-sealable wrapping material 13, e.g. rubber hydrochloride film, is fed from a supply roll 15 and positioned over the surface of a conveyer comprising a number of buckets 6 lined with sponge rubber 7 and interconnected by pivot pins 9 which are engaged by recesses 12 in intermittently-rotated star wheels 10 and 11. Each pin 9, Fig. 12, is provided with a row of projections 20 which pierce the web whereby the web is advanced at the same speed as the buckets. A second web 18 of similar material is fed from a supply roll 17 over rollers 22, 23 and a vertically-movable tensioning roller 21 and passes over bars 32 carried by a pair of rotatable rings 30 carried by vertically-movable bearings. These bars have bifurcated ends adapted to be engaged by rollers 51 on the pins 9, so that the rings are rotated as the buckets are advanced, and are provided with projections similar to those on the pins 9 so that the web 18 is drawn from the supply roll and positioned over the web 13 at the wrapping-station. The unwinding of the supply rolls is controlled by straps 25 and 28 tensioned by weights 27 and 29 respectively. Specification 696,562, [Group XVII], is referred to.

Title: Improvements in or relating to safety tubes and safety walls for tires
IPC: B60C5/12
Filed: 1949-09-21
Abstract: 658,465. Pneumatic tyres. GOODRICH CO., B. F. Sept. 21, 1949, Nos. 24252 and 24253. Convention dates, Sept. 27, 1948, and March 16, 1949. [Class 144 (ii)] A dual chamber " safety " pneumatic 'tyrein which the inner tube 10 is normally spaced from the inner tread portion of the cover 20, leaving an inflatable space between this tube and the cover, the tread 13 and sidewall portions of the tube are reinforced by inextensible material, the base-portion 12 being extensible so as snugly to hug the rim. As shown in Fig. 3, the side walls of the tube are provided with reinforced flaps 23. Inflation is effected through a valve 11 directly into the tube 10 from which, through a small aperture 22, air passes into the space under the tread of the cover. In the event of deflation of this space, collapse of the tube 10 is delayed owing to the slow seepage of air through the bleed-hole 22. For use on flat-base rims, the rim-seating portion of the air-tube may be reinforced by circumferential wires or like reinforcing material. In further modifications, the air-tube is open to the rim and has edgeflaps air-tightly sealed between the tyre-beads and the rim. The outer faces of the tyre-beads may be formed with rim-engaging sealing- grooves as described in Specification 648,976.

Title: Improvements in or relating to collapsible tower cranes
IPC: G01P21/02
Filed: 1969-05-13
Abstract: 1,263,778. Self-erecting tower cranes. SOC. POTAIN. 13 May, 1969 [14 May, 1968]. No. 24314/69. Heading B8B. [Also in Division E2] A self-propelled tower crane comprises a chassis 1 on wheels 2 and supporting a slueing platform 3 carrying a mast 10 with a telescopic jib 15, 16 which may be extended by a lifting cable 19 from a winch 5 when the jib 15, 16 is raised. Fig. 1 shows the crane in its travel position. To erect the crane at a work site stabilizers 37 are unfolded and the mast 10 and jib 15, 16 turned across the chassis 1, Fig. 3. Hook 6 is attached to the chassis 1 and the winch 5 operated until the mast 10 is vertical when it is pegged in place. The hook 6 is detached from the chassis 1 and by winding cable 32 on winch 7 the jib 15, 16 is partially raised to a position where it is supported by a detachable prop 31, Fig. 5. The jib components 15, 16 are unlatched one from the other and the component 16 extended by winding the cable 19 on winch 5, see Fig. 17, when the components 15, 16 are again latched together (see Division E2). In a modification, Fig. 10 (not shown), a third winch drum (44) is provided for raising the mast 10 using a cable (45). Fig. 18 shows a modification in which the mast 49, 50 is telescopic as well as the jib 15, 16 and the reeving of the cable 32 is modified as shown. In this case winding the cable 19 on the winch 5 with winch 7 stationary results in simultaneous raising of the mast 49, 50 and its partial extension. After the mast 49, 50 has been pegged in its vertical position its extension is completed by winding the cable 32 on the winch 7, leaving the winch 5 free. The mast components 49, 50 are then wedged together (see Division E2). Fig. 26 shows a further modification wherein a winch 116 and a cable 117 are provided solely to raise the mast 10. A balance bar 108 pivoted on a shaft 111 on the platform 4 is connected at one end 113 by a sling 114 to post 11 on the mast 10 at a point 115 and at the other end 107 by a sling 106 to pulleys 103 which are part of a tackle of jib cable 101 from the winch 7. The sling 106 is thus held permanently taut.

The layer is then coated with a radiation-sensitive layer e.g. a photographic silver halide emulsion layer to form a photographic film. In Examples, layers of thicknesses from 30 to 150 angstroms comprising 50 : 50 or 70 : 30 ratio by weight mixtures of chromium and silicon monoxide are vapour-deposited on film supports from chromium and silicon monoxide cermets heated by an electron beam.

Abstract: 1,063,592. Laminates and laminating. DOUGLAS AIRCRAFT CO. Inc. June 16, 1964 [June 17, 1963], No. 24991/64. Heading B5N. [Also in Divisions G2 and H4] A screen for a cathode-ray or like tube for absorbing stray light comprises a stack of transparent sheets, e.g. of cellulose acetate or ethyl cellulose, having printed thereon a pattern of fine lines, or crossed lines forming squares, diamonds &c., the patterns being made to register with one another by forming the sheets with lines or a pattern of interengaging conical pips which bear a fixed spatial relation to the patterns. Screens having a directional lightabsorbing effect are made by slightly staggering the lines in successive sheets, this being secured by impressing in the sheets pips with their axes slightly inclined to the normal. The sheets may be secured together with thermoplastic or wet adhesive. To form the sheets a web 10 drawn from a roll 11 is passed between rollers 12, 14, edge portions of which are formed respectively with conical bosses 16 and complementary recesses 18 to produce spaced pips 20 in the web. For this purpose the rollers, or the edge portions thereof, may be heated. The web then passes between correspondingly formed rollers 21, 23, the latter of which is engraved with a line pattern which is printed on the web with a medium supplied by inking rollers 28, 30, whereas the former applies adhesive to the underside of the web by rollers 36, 38. The web passes around the roller 21 and is cut into lengths by rollers 44, 46 carrying a knife 48 and a co-operating groove respectively. The cut lengths are superposed with the printed patterns in registration by means of the interengaging pips and are pressed in a press having platens which are heated if a thermoplastic adhesive is used and which are formed with bosses and recesses corresponding to the pips in the sheets. The edge portions of the completed laminate bearing the pips are trimmed off before it is applied to the C.R. or other screen. In a modified apparatus several units such as that shown are arranged to supply sheets in superposed relation, together with an upper sheet bearing no adhesive, to a pair of laminating rollers which deliver to means for cutting the laminate so made into the required lengths.
