Title: Improvements in and relating to Overhead Rope Railways and the like.
Inventor: WHITE JOSEPH WALWYN
IPC: E01B25/18
Filed: 1917-10-12
Abstract: 127,354. White, J. W. Oct. 12, 1917. Rope railways.-A suspended rope track having the tensioned ropes held at tensioning-posts is provided with intermediate supporting-posts to which the rope is secured by means of clamping- devices. Fig. 1 shows the saddle portion 1 with a central depression 3 into which the rope 4 is forced by an adjustable clamping-plate 5 or hook having a screwed shank held by a nut 8. The plate is formed to hold the rope in the depression 3 and to form a smooth running surface 9. At tensioning-posts, the ropes may be similarly held and a running surface thus formed, the ends of the ropes being fixed under additional clamps 17 or to the post itself, in some cases the ropes acting as guys. The invention is stated to be particularly applicable to such ropeways as are de,- scribed in Specifications 16428/97 and 24367/05.

Title: Improvements in and relating to apparatus for the automatic regulation of infinitely variable automobile gears
IPC: F16H61/662
Filed: 1958-05-09
Abstract: 878,850. Change-speed control. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. May 9, 1958 [May 11, 1957], No. 14920/58. Class 80 (2). In a vehicle having a steplessly variable-speed gear the ratio is automatically varied in such a way that each setting of the engine throttle valve corresponds to a definite engine speed. As shown, the ratio of an expanding pulley gear 106, 107 is controlled by a servomotor S supplied with liquid by an internal gear pump 35 through a control valve V. Valve V comprises co-operating sleeves 38, 42 controlled by a footoperated pedal 2 and an engine driven governor G respectively. Pedal 2 is connected by a rack and pinion 4, 6 to a shaft 7 which is connected by a rack and pinion 5, 79 to the sleeve 38. Shaft 7 is also connected through a cam mechanism to the engine throttle valve 33. With the pedal 2 in a particular position, if the load varies (e.g. due to hill climbing), the engine speed alters and governor G displaces sleeve 42 so that lands 44, 45 on the sleeve uncover ports 39, 40 in sleeve 38. Pump 35, which is driven by the engine shaft 46, then supplies liquid through a duct 82 and port 39 or 40 to the servomotor to vary the gear ratio. As the ratio varies the engine speed is restored to its former value and sleeve 42 is restored to its former position by the governor. On operating pedal 2 the throttle valve 33 is moved to a new position and valve sleeve 38 is moved axially, uncovering ports 39, 40 so that the servo motor is supplied with liquid to alter the gear ratio. The engine speed changes due to the change in ratio and in the setting of the throttle so that the sleeve 42 is moved by the governor to close ports 39, 40. The governor can be adjusted by varying the loading of a spring 68 so as to give a desired engine speed for any particular setting of the throttle. It is thus possible to ensure that the engine always gives its most economical performance.

Title: Improvements in or relating to the separation of dust and other small particles from gases
IPC: B01D45/14
Filed: 1936-05-28
Abstract: 475,884. Centrifugal dust-separators. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) May 28, 1936, No. 15036. [Class 23] A dust-laden gas stream is passed through a bladed fan member which precipitates centrifugally the coarser particles, and the stream is conducted to the outer edges of a number of closely-spaced rotating discs from which finer particles are thrown while the gas passes radially inwards between the discs and thence to the discharge outlet. The casing has two parts 5, 6 ; the latter 6 has perforations 10 for the expulsion of air, and the former 5 has an inlet 9 below the level of the shaft 60 which is supported in bearings 61 and driven by a belt 63. The collar 65 secured to the shaft 60 has a conical flange 68 which is slotted to support one end of each fan blade 76 the other end of which is supported by the ring 71. A nest of conical discs 98 is held by bolts 82 between the flange 68 and the spider 84. A fan 108 within the part 6 of the casing draws the gas stream through the apparatus. The dust-laden stream undergoes a sharp change of direction in passing from the casing inlet 9 to the entry of the rotor between the fan blades 76. This change causes the coarsest particles to pass through the slot 38 in the casing into the drawer 34. The stream passes into the rotor and is drawn radially inwards between the discs 98 ; it then passes to the discharge outlets 10 through the fan 108. While passing through the rotor the dust particles are thrown outwards centrifugally to the conical surfaces 78, 89. Particles travelling outwards between the discs 98 coalesce and form larger particles which join the finer dust on the surfaces. This separated material slides outwards and passes through the slot 96 between the surfaces 78, 89 into the annular trough 54 from which it is discharged through the slot 41 into the drawer 35. If dust tends to accumulate in the chamber 50 it can pass through the slot 52 and the hole 53 to be entrained by the stream entering the rotor for treatment. The fan 97 acts as a seal to prevent leakage of dust from the rotor by drawing air into it mainly from the space between the plates 13, 15. The dust may be collected in bins with regulatable discharge valves instead of being collected in the drawers 34, 35.
