Title: Improvements in and relating to fluid-pressure power installations
IPC: F01B17/04
Filed: 1935-12-13
Abstract: 467,504. Reciprocating engines; marine power plant. WHITE, W. A., and WHITE'S MARINE ENGINEERING CO., Ltd. Dec. 13, 1935, No. 34680. [Classes 110 (iii) and 122 (iii)] Comprises a condensable, fluidpressure reciprocator with two or more stages, in which the crankangles are chosen to give a good mechanical balance, and superheating is effected between the stages so that the low-pressure cylinder does more work than a higher-pressure cylinder in the ratio of from 1À3 to 1 to 1À1 to 1. In a specific construction, the H.P. cranks are at 55‹ and the L.P. cranks at 108‹ apart. In the double-compound engine shown, which may be used in the power-plant described in Specification 362,255, high and low-pressure cylinders A<1>, A<2>, B<1>, B<2> are arranged as shown. The low-pressure cylinders are adapted to do more work than the high-pressure cylinders in the ratio of 1À3 to 1. The H.P. exhaust is superheated by superheated steam before entry into the L.P. cylinder. The reheater comprises heat-transferring units C<1>, C<2> with internal tubes c secured to the backs of the engine and fed with superheated steam through a fitting D, the steam passing through a pipe e to the H.P. valve chests. The H.P. cylinders exhaust, through pipes f, f and the heaters C<1>, C<2> to the L.P. chests b<1>, b<2> respectively. The L.P. cylinder's exhaust from pipes i, i<1> passes through a pipe k to the turbine, or by a change-over-valve to the condenser. The reheater tubes may be bent to conform to the plan of the engine. Instead of a three power-shaft arrangement as described in the above Specification, the crankshaft may drive directly the propeller shaft, and the turbine geared to it. Alternatively, the turbine may drive the auxiliaries. The reciprocating-engine may be used alone.

Title: Improvements relating to the feeding of web material to cigarette tipping apparatus and other machines
IPC: A24C5/58
Filed: 1936-12-19
Abstract: 487,251. Feeding webs. DEARSLEY, G., and INDUSTRIAL MACHINERY CO., Ltd. Dec. 19, 1936, No. 34964. [Class 100 (i)] Means for feeding material in web form from a supply reel to a severing-mechanism comprises intermittently or continuously operating web-feeding means located in the path of the moving web before the latter reaches the severing-mechanism, and a continuously-driven roll or drum intermediate the feeding means and the supply reel and with which a lap of the web is adapted to engage to provide a friction drive for drawing the web from the reel, the peripheral speed of the roll or drum being greater than that of the feeding means. The invention is described as applied to a mechanism for feeding foil for a cigarettepacking machine, the foil web 10 being drawn intermittently from a reel 12 to a severing- device by a pair of feed rolls, one of which is driven through a Geneva mechanism, the web on its way to the feed rolls passing between a pair of detecting rolls 21. Between the feed rolls and reel 12 is a continuously-driven flanged drum 11 around which the web passes, the drum being driven at a high speed to provide a friction drive for the web to draw it from the reel, and having a serrated surface or a coating or covering so that it grips the web frictionally. The web is passed over a roll 16 prior to engaging the drum 11, and the roll, or the arm supporting the roll, can be adjusted to adjust the are of contact between the web and the drum 11. Between the drum 11 and rolls 21 there is a tensioning-device for the web comprising a roll 13, around which the web passes, mounted on one end of a pivoted arm 14, the other end of the arm having a tension spring 15 attached thereto. In operation, during the driving period of the intermittent feed rolls, the web is maintained taut and in engagement with the rapidly rotated drum 11 and thus a frictional drive is imparted to the web to assist the feed rolls. During the non-driving period of the feed rolls there is a slackening of the web so that the drum 11 imparts no drive to the web. If, however, the roll 13 takes up the slack in the web during the non-driving period, the web will be drawn continuously from the reel 12. The intermittent feed rolls may be replaced by continuously-rotating feed rolls. The drum 11 is driven by gearing 18, 20. Specification 464,161, [Group VI], is referred to in the Provisional Specification.

Title: Improvements relating to electrical insulating structures
IPC: H01B17/38
Filed: 1955-12-06
Abstract: An electrical insulating structure comprises a ceramic body, such as a porcelain part, a metallic body and a hardened cement, the cement and ceramic body being in series between the conductive bodies, and wherein the hardened cement has a dielectric constant at least equal to the dielectric constant of the ceramic body and the cement itself comprises a polymerizable polyester or epoxy resin and a filler of dielectric constant of at least 30, e.g. titanium dioxide, alkaline earth titanates and stannates and impure alumina (as specified in the Specification).  The polyester may be derived from unsaturated polybasic acids and/or unsaturated polyhydric alcohols and may be modified with the usual monohydric alcohols and/or saturated polybasic acids.  Specified unsaturated polyester components are maleic, fumaric and itaconic acids.  The polyester is preferably used in conjunction with a vinyl or allyl monomer such as styrene, vinyl acetate, triallyl phosphate, a diallyl ester (several listed), methyl acrylate or methacrylate, dioctyl or dibenzyl itaconate, or diethyl or dibenzyl fumarate. The polyester resin when used may be cured in situ in the structure by heat alone or by the use of a catalyst selected from barium and sodium peroxides, benzoyl, acetyl, lauroyl and stearoyl peroxides, and acetyl benzoyl, acetone and triacetone peroxides. The epoxy resins used are derived from epichlorhydrin and polyhydric phenols or alcohols such as glycerol, diphenylol propane, and the mixed poly-(hydroxy phenyl) pentadecanes derived from cashew nuts, and may be cured in situ in the structure by the use of cross-linking agents such as polyamines (e.g. diethylene triamine) and dibasic acid anhydrides (e.g. phthalic anhydride). The cement may also comprise minerals such as silica, talc, clay, mica and sand, for the purpose of viscosity control.  Insulating structures specified and described are support insulators and enclosures for cut-outs and lightning arresters, suspension insulators for power lines, support insulators for bus-bars and switchgear, and bushings for transformers and capacitors.

Filed: 1953-12-23
Abstract: 768,686. Stoppering bottles. KORK-NSEAL, Ltd. Jan. 7, 1955 [Dec. 23, 1953], No. 35748/53. Class 125(2). [Also in Group XXX] Cylindrical containers resting on a conveyer band 10 are rotated about their axes to bring projections 180, or other parts of the containers, into alignment, whilst continuing to travel in the direction of the band, with a position of application of caps, labels or other means thereto. The rotation is effected by two pairs of continuously driven belts 16, 17 mounted on pairs of pulleys 20, 21, 22, 24 and 25, 27, 28, 30 respectively. The respective sets of pulleys are mounted on plates 80, 56 carried by laterally slidable frames 72, 40 respectively. The plates are vertically adjustable on the frames by studs 54 bolted to the frames being engaged by threaded hollow portions of knobs 53 rotatably mounted in the plates, vertical guiding of the plates being provided by telescoping tubes 50 welded respectively to the plates and frames. The frames are provided with collars 41, 43 slidable along rods 34, 35. Springs 45, 46 urge the frames away from the band 10 so the belts 16, 17 are normally free of the sides of the containers. The pulleys 20, 25 are driving pulleys and each is a split type having a spring device 61 for urging the rims together. Each pair of driving pulleys is mounted in a bearing 57 adjusted on its respective plate 80 or 56 by a screw 59, to tension the belts, and is connected by a universal joint 63, floating shaft 64, and universal joint 65 to a driving shaft 66. The two driving shafts are connected together by sprocket gearing 171, 172, 173, the sprockets being of different sizes and the arrangement being such that belts 17 travel forwards at the speed of the band 10, and belts 16 travel backwards at a slower speed. The drive is taken from a shaft 70 of a capping machine to which the bottles are being fed. When a bottle approaches the belts it engages a trip lever 111 to close a switch 110 which energises a solenoid 109, Fig. 6. This rotates a rod 105 causing adjustable bolts 101 on levers 102 to rock a pair of bell cranks 99, 100 having respective forks engaging collars 85, 86 on studs 83, 84 secured to the respective frames 72, 40, whereby the frames are moved towards the band 10 and belts 16, 17 grip and rotate the container. When the projection 180 is rotated to a position in alignment with the belts 16, it engages one or both of a pair of bars 130, 133 extending in line with the belts. Each bar is mounted at its ends on a pair of plungers 124, 126 spring-urged towards the band 10 which engage the actuating levers 119, 120 of stop switches 117, 118. Engagement of either bar by projection 180 depresses the plungers and opens both stop switches to deenergize solenoid 109 which allows springs 45, 46 to return the frames 72, 40 so that belts 16, 17 release the bottle in the correct position for the application thereto of a cap.
