Title: Improvements in or relating to apparatus for dispensing petrol
IPC: B67D7/08
Filed: 1955-12-29
Abstract: 845,748. Dispensing petrol. TOPLEY, J., and BOWSER INTERNATIONAL Ltd. March 26, 1957 [Dec. 29, 1955], No. 37337/55. Class 116 Apparatus for dispensing petrol comprises means for delivering petrol from a storage container to a petrol outlet, a driving connection which includes a clutch between the delivery means and a pair of hands which indicate on a dial the quantity of petrol delivered, a computer mechanism driven from the delivery means and operating means to indicate the. cost of the petrol delivered, manually - operable resetting means for the dial hands and the cost indicator, and means for disengaging the driving connection during resetting. Dial hands 22, 24 (Fig. 5) are driven from a shaft 21 through a cone clutch 102, 103 and cost computer wheels 78 are driven from the same shaft through gearing including a clutch 176 and gearing 178, 179. "Sweep" hands 22 are driven direct from shaft 11; "unit" hands 24 are driven through transfer mechanism comprising disc 26 with pressedout radial arm 27, Fig. 1, double pinions 28 normally locked against rotation by wide teeth 45 engaging edge of disc, but rotated through one unit on dial for each revolution of shaft 11 by arm 27 engaging part 44 of double pinion, and gears 32, 33, the latter attached to sleeve 34 carrying hand 24. Other hand 24 is rotated through gears 41, 42, 39. Resetting by manual rotation of shaft 89 (Fig. 5) causes worm 52 (Fig. 1) to rotate pinion 53 carried, free of shaft 11, by reset discs 54, and hence to rotate the discs 54. At the appropriate points pawls 61 carried in corresponding radial positions by discs 54 engage respective recesses in cam 55 on shaft 11 and cam 56 on sleeve 34 to return the hands to zero. The dial hands are freed by the initial motion of shaft 89 (in clockwise direction, Figs. 5 and 6) causes pin 115 (Fig. 6), to move plate 114 about shaft 90 and thereby to raise cranked arm 116 about its pivot 117 and to lower shutters 122. Rotation of shaft 117 causes arm 127 (Fig. 5) to move fork 128 and release clutch 176 while at the same time strut 131 moves arm 104 about pivot 1171 and projection 105 releases cone clutch 102, 103, thus allowing resetting of dial hands and cost computer. Also projection 144 (Fig. 6), on cam 112 attached to shaft 89 moves cam plate 141 anticlockwise to a position in which lug 139 on spring-biased arm 133 (pivoted at 134 and normally held in position shown by nose 138 on cam plate 114) engages a rectangular recess. This controls, through a linkage not shown, the position of a rectangular frame 151, Fig. 5, which is allowed to pivot about shaft 89 until a projection at its lower end is positioned to contact a stop 159 on shaft 11, on completion of resetting.

Title: Improvements in or relating to aircraft flight controls
Inventor: STRANG WILLIAM JOHN
IPC: B64C13/24
Filed: 1954-12-24
Abstract: 790,632. Controlling aircraft. BRISTOL AIRCRAFT, Ltd. Dec. 15, 1955 [Dec. 24, 1954], No. 37407/54. Class 4. A fixed wing aircraft of the kind having an elevator hinged to the airframe structure and operated by a servo-tab system at the trailing edge of the elevator, which servo tab system is in turn operated by a pilot's control member, so that movements of the elevator do not react upon the control member, is provided with resilient means which act to produce a moment urging the elevator towards a downwardly deflected setting. Each tailplane 13 carries an elevator 14 which in turn carries a plurality of tabs 15, 16, 17, 18. The nose portion of the elevator carries an attachment 31 and a bearing 32 for a torsion spring 30 which carries a lever 33 connected by a link 34 to a fixed pivot 35 on the tailplane. The lever and link are so arranged that the spring is pre-stressed to an extent that depresses the elevators fully when the aircraft is stationary. The tab 15 carries a lever 52 connected by a link 49, bell-crank 48 and push-pull rod 46 to an arm 45 secured to a gear sector 44 which meshes through a gear 43 and a worm drive 39 with a reversible electric motor 41 controlled by the pilot through a switch 50. In flight the tab 15 is adjusted so that at normal speed and loading with the pilot's control member in neutral setting, each elevator will take up a substantially neutral position in which it forms a fair continuation of the profile of the tailplane. An unwanted nose-down pitching moment on the aircraft resulting from an increase in speed results in an increased upward thrust on the tabs 15 so that the elevators are raised against the action of springs 30 to provide a nose-up righting moment. Conversely, a decrease in speed is accompanied by a nosedown righting moment on the aircraft.. The tabs 16, 17, 18 are operated in unison as servo tabs to control the elevator and each is connected by a lever, link and bell-crank to a control rod 63 located on the elevator hinge line and connected to a lever 62 of a gear sector 61 driven through gearing 54, 55, rod 56 and gearing 57, 58 from a pilot's control member 40. " Feel " is applied to the member 40 by a spring 69, which may be adjusted by a slider 70 operated by a control wheel 72 to trim the tabs 16-18. In a further embodiment, Figs. 5 and 6 (not shown), the torsion spring 30 is dispensed with and the elevator is provided with three trailing- edge tabs, one for controlling, as a servo-tab, the pitching movements of the elevator ; a second for trimming the position of the elevator and a third which is connected to the elevator by a spring offset upwardly from the chord line so that the tab is biassed upwardly to tend to depress the elevator when the aircraft is in flight.

IPC: H01C17/065
Filed: 1962-10-04
Abstract: An electrically-conducting coating for application to ceramic articles comprises a precalcined mixture of tin oxide and antimony pentoxide incorporated in a non-conducting ceramic glaze. The mixed tin and antimony oxides form 25 to 45% by weight of the total glaze composition.  The conducting oxide is formed by mixing and calcining 95 to 99 mol.% of tin oxide with 1 to 5 mol. % of antimony pentoxide. A conducting glaze suggested for a porcelain insulator consists of in weight percentages, felspar 20.2; calcium carbonate 12.7; magnesium carbonate 1.5; china clay 9.4; quartz 26.2; conducting oxide 30.0. The glaze is applied to the porcelain by spraying or dipping and heated to 1200-1250 DEG  C. to fire the porcelain and vitrify the glaze.  If a glaze of lower melting-point is used, but not containing lead, the article is pre-fired.  As well as insulators, the coating is useful for floor and wall tiles particularly for operating theatres and places where static electricity charges are likely.

Title: Carriage decelerating mechanism for telegraph page printers
IPC: H04L13/18
Filed: 1963-09-20
Abstract: 1,041,068. Selective printers. TELETYPE CORPORATION. Sept. 26, 1963 [Oct. 15, 1962], No. 37887/63. Heading B6F. Letter - spacing mechanism; carriage return mechanism; sound-deadening and shock-absorbing devices.-A carriage decelerating mechanism for a telegraph page printer comprises a dash-pot 10, Fig. 1, mounted on a side plate 149 and into which a plunger 11, mounted on a type head carriage 145 is caused to enter as the carriage completes its return movement the plunger 11 having a cup-shaped member 18, Fig. 2, mounted on a stud 22 for radial frictional displacement, so that, if initially misaligned the dash-pot and plunger can be brought into alignment by the engagement of a chamfered edge portion 13 on the dash-pot 10 with an opposed chamfered edge portion 32 on the plunger 11 thereby permitting proper entry of the plunger within the dash-pot to absorb the shock of the returning carriage. The dash-pot 10 is provided with an exhaust port 15 the size of which may be controlled by a lever 16 which is pivoted on the shank of a locking screw 17. The plunger 11 is provided with a soft rubber disc 20 forced into the member 18, which serves to cushion the shock of the carriage return operation when a carriage return signal is received before the plunger has been withdrawn from the dash-pot. In operation the carriage 145 is moved step-by-step by an endless belt 460 having teeth 461 cooperating with a toothed gear mounted on a shaft 463 which is driven by a ratchet-wheel 466 actuated by a driving pawl 467, which in turn is actuated each time the telegraph printer receives either a character code or a space code combination. The ratchet wheel 466 is retained in its advanced position by a detent pawl 468. The letter-spacing movements serve also to tension a coil-spring 488, passing over a guide roller 491 and whose one end is hooked over a stud 489 mounted on the carriage 145. On receipt by the printer of carriage-return operation code signal a pawl release lever 480 is actuated to disengage the driving pawl 467 and the detent pawl 468, to permit the tensioned coil-spring 488 to return the carriage 145 to its extreme left-hand position. Type carriages; hammer impression arrangements; type-wheel machines; web and strip arrangements.-The carriage 145, which supports a type-wheel 186 and its associated print hammer 293, is moved across the printer to associate the type-wheel 186 with succeeding areas of a web of paper on a platen 271 and guided by guide rollers 151, 155, which are mounted on extensions 153, 156 of the carriage and ride on the guide rod 146.

Title: A method and a device for purifying industrial and domestic effluents and for utilising the solid matter contained therein for the generation of energy
IPC: C02F9/00
Filed: 1960-11-07
Abstract: A fuel gas is made by gasifying with air and/or steam and/or oxygen a mixture of a sludge separated from industrial and domestic effluents containing solid matter which is mostly of an organic nature and dried to a water content of not more than 30% by weight with carbon and/or carbon compounds.  Suitable materials for mixing with the sludge are coke, coal, coal dust, tar, pitch, oil residues and spent sulphite lye.  The mixture may be briquetted with the addition of a binder and other solid industrial or household refuse may be incorporated in the mixture after a magnetic separation treatment. The effluent is first treated in a settling basin possibly with the addition of peat or sawdust to absorb colloidal, oily and tarry constituents of the effluent.  The sludge from the settling basin is then mechanically dried and optionally by heating to a water content of less than 30% and preferably between 5 and 25% by weight.  The amounts of carbon and/or carbon compound added to the dried sludge may be varied to produce a constant supply of gas.  The gas may be burned in a gas engine or turbine to produce electrical energy and the waste combustion gases used to dry the sludge.

Title: Accumulation conveyor
IPC: B65G47/28
Filed: 1969-07-30
Abstract: 1283963 Roller conveyers LOGAN CO 30 July 1969 [30 July 1968 31 Oct 1968] 38321/69 Heading B8A An accumulation conveyer includes rollers 18 which, due to compression springs (58), Fig. 6 (not shown), normally press an endless belt 16 into driving engagement with carrying rollers 14 but which, by means of inflatable air hoses 66, may be lowered such that there is only light frictional engagement between the belt and the rollers 14. A pivotable stop roller 8 controls the hose air supply and, by providing a series of check valves in the hoses 66, the lowering of the rollers 18 at the downstream end of the conveyer is greater than that at the upstream end. Accordingly, between the upstream and the downstream ends there will be a progressive reduction in the driving force exerted on articles A. The articles are released by actuating a cylinder 116 connected to the mounting of the stop roller 8 and by deflating the hoses 66. The roller 8 is raised in response to the operation of a photo-cell device downstream of the roller when an article is stopped for longer than a predetermined minimum period. The roles of the springs (58) and of the hoses 66 may be reversed, i.e. the hoses may be deflated to cause the rollers 18 to be lowered.  In a modification, Fig. 11, control of air pressure to sections of hose 206 for lowering pairs of pressure rollers 192 is provided by sensor rollers 194 normally raised above the plane of carrying rollers 182. When a sensor roller 194 is depressed a valve 202 is actuated by an extended axle 196 of the roller and the associated pair of rollers 192 is lowered. Momentary depression of a sensor roller 194 is insufficient to cause lowering of the rollers 192. In a further modification, Figs. 17-19 (not shown), pressure rollers (302) are individually supported by pairs of air tubes (306) under the control of sensor rollers (314).

Title: Reversible flat keys for cylinder locks
Inventor: WOLTER HEINZ
IPC: E05B27/10
Filed: 1976-09-16
Abstract: The reversible key (12) has run-on slopes (17-20) located at the tip and designed as individual grooves extending beyond the longitudinal mid-plane of the key. Double rows (I, II or I', II') of depressions (16 or 16') for classifying the tumbler pins of the cylinder lock are provided on the two wide sides of the key. A double row (I, II) of one wide side of the key is arranged offset relative to the double row of the other wide side of the key in the transverse direction of the key. The run-on slopes (17-20) are assigned to the rows of depressions (I, II, I', II'). Because the rows of depressions (I, II, I', II') are arranged offset relative to one another, the run-on slopes (17-20) are arranged staggered relative to one another. The rows of depressions (I, II) of one right side of the key are arranged at a mutual distance (x) symmetrically relative to the core axis (KA) of the cylinder lock. With the flat key (12) inserted, the key axis (SA) is offset at x/4 to the core axis (KA). On the opposite right side of the key, the rows of depressions (I', II') are in a correspondingly offset position relative to the key axis (SA). The core axis (KA) coincides with one (II') of these two rows of depressions (I', II'). The depressions (16) marked by broken lines co-operate with the core pins of the tumbler lock, whilst the depressions (16') located on the other right side of the key remain unused. When the flat key (12) is reversed through 180 DEG , these depressions (16') come into effect. <IMAGE>
