Title: Improvements in and relating to vehicular amusement devices
IPC: A63G15/00
Filed: 1933-06-02
Abstract: 420,311. Horse &c. velocipedes. PLANT, F. W., Cambridge Arterial Road, Enfield, Middlesex, and ROE, J. A., 51, Beaconsfield Road, Lower Edmonton, London. June 2, 1933, Nos. 16096, 18973, and 19878. [Classes 136 (ii) and 136 (iii)] In horse and like velocipedes of the type in which, to effect propulsion, pivoted front and rear pairs of legs are moved towards and away from one another by the alternate action of the weight of the rider on stirrups and on the body or seat, backward movement of the legs relatively to the ground being prevented, e.g., by one-way clutches, the legs are pivoted at their upper ends at or near the ends of the body, and the connections of the legs with the stirrup comprise two two-armed levers pivoted upon the front and rear legs respectively, links connecting corresponding arms of these levers directly or indirectly with the stirrup, and means (e.g., the body and links or the links alone) interconnecting the other arms of the levers so as to provide floating fulcra therefor. The front legs 11 and the rear legs 14 are pivoted at 12, 15 respectively to the body 13, their pivotal movements being limited by outer stops 16, 17 and inner stops 35, 36. Pivoted to the legs 11, 14 at 18, 19 respectively are two-armed levers 20, 21, one end of each of which is pivoted to links 23, 26 pivoted to the body, so as to provide floating fulcra at 22, 25. The other ends of the levers 20, 21 are connected by links 31, 33 to crank arms 32, 34 on a shaft 28 on the body, another crank arm 29 on the shaft 28 being pivoted to a stirrup member 30. When the rider transfers his weight from the body 13 to the stirrup 30, the legs 11, 14 move towards one another to the position shown in dotted lines, the front and rear wheels 37, 38 rotating, while during the return or outward movement of the legs, the rear wheels 38 are prevented from rotating by a ratchet and pawl 39, whereby the device will be propelled forwards. The front wheels 37 are steered from a handle 40 through a shaft 41, a universal joint 42, a cranked rod 43, two cross members 45, and cranked steering-columns 47. In the modification shown in Fig. 2, the shaft 28 is slidable in vertical guides 48 and is supported by a pair of rigid longitudinal members 49, which are connected at the ends by links 50, 51 to the pivots 18, 19 of the two-armed levers 20, 21. Propulsion may be assisted by a reciprocating chain 52 adapted to drive a freewheel sprocket 55 on the rear wheel axle, and connected at one end by a link 53 to the lower end of the lever 20 and at the other end to a return spring 56 linked at 57 to the crank arm 34 on the shaft 28. In a further modification, the two-armed levers are connected together by crossed links, and one of the levers is linked to the body to maintain alignment. The lower ends of the legs may be provided with slidable rollers controlled by springs and linkwork so as to be brought into engagement with the ground only on forward movement of the legs, which engage non-slidably with the ground on the reverse movement.

Title: Improvements in and relating to heaters for mixture used in explosion engines
IPC: F02M1/00
Filed: 1920-06-16
Abstract: 145,067. Boin, R. Feb. 28, 1914, [Convention date]. Vaporizers, external.-Mixture, on its way from the carburettor outlet 3 to tho inlet manifold 8, passes through a straight cylindrical chamber 2 heated by exhaust gases entering at 1 and leaving at 4. To ensure that all unvaporized portions of fuel shall come into contact with the heated wall of the chamber 2, the inlet to the chamber may be by way of apertures 7 formed by punching triangular flaps 6 from a disk 5. The flaps, being obliquely arranged, impart a swirling movement to the mixture and direct it against the hot wall. The Specification as open to inspection under Sect. 91 (3) (a) states also that in place of the flaps the heated portion of the mixture passage may be given a coiled form and instead of imparting gyratory motion, the mixture may impinge against one or more baffle-plates, perforated sheets, or the like. This subject-matter does not appear in the Specification as accepted.

Title: Improvement in cigar finishing device
IPC: A24C1/32
Filed: 1924-07-07
Abstract: 233,921. Marks, E. C. R., (International Cigar Machinery Co.). July 7, 1924. Cigar-making machines. - In machines in which the cigar, after being wrapped, is re-rolled, the consequent loosening of the wrapper is remedied by knurling the head of the cigar. As shown, the cigar, rerolled by a belt 10 and a roller 3 oscillated by a rack and pinion, is held by clamps such as 13 and is re-knurled by a thimble 33 rotated through gearing, 36 from a. shaft. 37. The clamp 13 is mounted on a rocking shaft 16 carried in a fixed bracket 17, and co-operates with another clamp, not shown, fixed in a bracket attached to the bracket 17. A vertical lever 24 rocked laterally by cam-actuated linkwork carries rollers 23, 31 engaging respectively a cam-face on a member 21 connected to the shaft 16 and a grooved collar on the spindle of the thimble 33. The motion of the lever 24 to the left disengages the roller 23 from the cam face, freeing the shaft 16. which is rocked by a spring 30 thereby causing the clamp 13 to engage the cigar. At the same time the thimble 33 is pressed forward to engage the cigar-head. An additional knurling thimble 34, furnished with a cigar-rest 35 and driven, through gearing from the shaft 37, may be provided. The shaft 37 is furnished with a clutch 40 engaging alternatively a pulley 38 driven from the machine shaft or an electric motor 42. The latter engagement enables the knurling thimble 34 to be used while the cigar-machine is at rest.

Title: Device for providing a seal between two fluids at different temperatures
IPC: F16L53/00
Filed: 1972-04-10
Abstract: 1332106 Joint-making packing COMMISSARIAT A L'ENERGIE ATOMIQUE 10 April 1972 [16 April 1971] 16416/72 Heading F2B [Also in Division G6] A seal device for providing a fluid-tight seal between a first fluid within a connecting tube 1, Fig. 1 and a second fluid externally of the tube, as in a sodium-cooled integrated fast reactor, in which the temperature of the first fluid exceeds that of the second fluid, comprising at each end of the tube a spherical collar 8, 9 for freely engaging within sleeves 13, 17 which are fixed to the walls 11, 16 of enclosures 2, 3 to be connected by the tube and which are formed with an internal diameter slightly larger than the spherical collars when the tube and sleeves are of the same temperature so as to permit assembly, means, such as insulation 7, for maintaining the tube at the temperature of the first fluid and means, such as a heat-insulating lining 12 and cooling fins 14 for controlling the expansion or contraction of the sleeves. As shown hot sodium flows from a primary vessel 2 containing a reactor core to a heat exchanger 3 and is sealed from the 'cold' sodium in the spaces 4, 5 by the clamping action of the spherical collars 8, 9 within the sleeves 13, 17. Relative movement of the enclosures 2, 3 is absorbed by the pivotal motion of the spherical collars, axial movement of the tube being limited by a stop 18. By use of heat insulators 7 and 12 and cooling fins 14 the tube 1 is maintained 'hot' while the sleeves are maintained 'cold', the clamping action being greater when the temperature difference between the fluids is greater. When the sleeves are in the cold state, the clearance between the spherical collars and the sleeves may be chosen to provide a desired leakage. The cooling fins may be replaced by hoops 14<SP>1</SP>, Fig. 2 which have a lower expansion rate than the sleeves upon temperature rise so as to produce a clamping action by restricting expansion of the sleeves; the tube may be made of austinitic steel while the hoop is made of an alloy of nickel, cobalt, chromium, molybdenum and carbon.

Title: A new or improved process of treating starch for the production of maltose and other substances
IPC: C13K7/00
Filed: 1923-06-28
Abstract: Starch is separated into amylopectin and amylose by freezing starch paste and treating the product with water or a dilute alkaline solution at a temperature of 50 DEG -60 DEG  C. to dissolve the amylose.  If the production of maltose is aimed at, the frozen starch paste is treated with an extract of ungerminated cereals, or with diastase prepared therefrom, at a temperature not exceeding 50 DEG C.  The maltose formed is separated from the residual amylopectin by solution in water at a temperature of 50 DEG -60 DEG  C. Alternatively, the enzymic treatment may precede the freezing operation.  The amylopectin which remains after any of the processes set out above may be converted into a size by heating with water.
