Title: Improvements relating to the wheel mountings of motor cycles and like vehicles
IPC: B62K25/02
Filed: 1928-03-20
Abstract: 298,854. Br³sselbach, C. March 20, 1928. Wheels, facilitating detachment of.-In a wheel mounting for motor-cycles &c. of the type in which the driving and braking torques are transmitted to the wheel by means of a fluted spindle which is axially withdrawable in order to enable the wheel to be removed without interfering with the driving and braking devices, the spindle supports the weight of the vehicles without any other engagement between the wheel hub and the bearing supports, and is provided with splines which extend along the entire length of the spindle and through the head at one end, and which fit accurately in grooves cut straight through the bearing bushes, as well as through the wheel hub. The fork ends are each provided with a split member 3 adapted to be clamped by means of a bolt 5 on to a ring 6, which is drilled eccentrically for chain adjustment and is screw-threaded to receive a bearing housing 7. Ball races 11, 12 are carried by a sleeve 13, and the hub 18 and sleeves 13 are fluted internally to engage with the fluted outer surface of the spindle 14, which is threaded at one end 20 to receive nuts 21 adapted to clamp the .parts together. The brake drum 25 is secured to a flange 24 on one of the sleeves 13, and the driving-member, such as a sprocket wheel 26, may be combined therewith as shown, or may be secured to a flange on the other sleeve 13. The brake drum 25 is provided with a shield 28 mounted on the boss of a threaded ring 30 and against a threaded spacing- ring 31 engaging a shoulder on the housing 7, which is thus clamped in position. The chainadjusting eccentrics on the two sides of the fork are actuated simultaneously and to an equal extent by means of a special coupling-shaft adapted to be passed through the sleeves 13 after removal of the fluted spindle. The wheel mounting may be applied to the front wheel, the eccentric adjustment being then omitted.

Abstract: 667,741. Automatic temperature control systems. VAPOR HEATING CORPORATION. April 4, 1950 [April 27, 1949], No. 8469/50. Class 38 (iv). In a temperature control system for a plurality of enclosed spaces, e.g. railway car compartments, each including a thermostat set to operate at a predetermined temperature, the thermostats 10, 11, 12 are connected in shunt with a relay coil 38 of a relay 37 which controls through relay contact 41 the energization of a heater valve 21 for supplying heat to all the compartments. The arrangement is such that only when all the thermostats are calling for heat will the relay 37 be energized so as to de-energize the heater valve coil 47 to open the heater valve. The thermostats each have an auxiliary heater 59, 60, 61 so that they may be cycled through relay contact 40. A blower fan for 18 is provided and is controlled by a relay 30 and an outside thermostat 22 so as to become de-energized when the outside temperature exceeds a predetermined value.

Abstract: 709,855. Autographic registers. SONDON SYSTEMS CORPORATION. April 7, 1952, No. 8848/52. Class 106 (1). [Also in Group XV] In an autographic register wherein a carbon copy of sales transactions is wound on a spool 39, rotation of the spool in the winding direction is effected by movement in one direction of a slide 53 having a finger piece 25 projecting through a slot 24 along one side of the apparatus. The slide carries a sprocket wheel 67 which engages a chain 45 driving the spool, a one-way clutch being provided between the slide and the sprocket wheel. The stroke of the slide is limited by a pawl and ratchet 77, 51 controlled by a feeler 70 which drops into a T-slit in the copying-strip 33 whenever the latter has advanced by the distance between two successive T-slits. The copy-strip is originally in folded zig-zag form. On reverse movement of the slide the clutch yields and allows the sprocket 67 to rotate idly along the chain. A rack 59 carried by the slide engages a pinion 81 which, on the reverse movement of the slide, drives a roller 82 through a one-way clutch. The roller carries spiked discs which engage the top, one of a pile of blank bill forms housed within the apparatus whereby a new bill form is ejected through a slit 83 on each reverse movement of the slide.

Title: Improved process and apparatus for the regulation of gas-turbine installations
IPC: F02C3/22
Filed: 1958-03-21
Abstract: 887,278. Gas turbine plants. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. March 21, 1958 [March 23, 1957], No. 9218/58. Class 110 (3). A gas turbine installation burning gaseous fuel comprises at least one gaseous fuel compressor and at least one air compressor and air may be mixed with the gaseous fuel before the inlet to the gaseous fuel compressor, the amount of air mixed with the gaseous fuel before compression of the mixture being dependent on the pressure of the gaseous fuel before compression, such that, at decreasing fuel pressure, the amount of air is increased, an amount of auxiliary fuel (say liquid fuel) being fed direct to the combustion chamber to produce the required output. The plant shown comprises a compressor turbine 5 driving an air compressor 3 and a gaseous fuel compressor 4, also a separate power turbine 2 driving a load 1. Air enters the compressor 3 at 6 and discharges through line 7 to air preheater 8, some heated air then passing through regulating valve 10 and duct 9 to the combustion chamber 12 to constitute primary air, and the remainder passing through the duct 11 to the combustion chamber to constitute secondary and dilution air. The combustion gases pass through duct 21 to the turbine 5 and then through duct 22 to the turbine 2, the gases discharging through duct 23 and air preheater 8 to atmosphere. A quick-opening valve 24 and an adjustable release valve 25 are provided in the duct 21 and a release valve 26 is provided in the duct 22. Gaseous fuel such as blast furnace gas is supplied through duct 13 having a main gas control 13a and a throttle valve 14 to the mixing valve 16 which is in the form of a rotary slide valve, and air is also supplied to this valve through duct 15. The mixing valve is connected to the gaseous fuel compressor 4 through duct 17, and the compressor is connected to the combustion chamber by duct 18 in which are mounted a quick-closing valve 19 and a release valve 20. Liquid fuel may be supplied to the combustion chamber from tank 27 by means of pump 29 in duct 28 containing regulating valve 30 and fuel nozzle 31. At no-load operation and during periods of partial load, the gaseous fuel compressor supplies a somewhat larger quantity of gaseous fuel than is necessary to meet the power requirements, this gaseous fuel being mixed with air before the inlet to the compressor, the combustion gases not required to meet the power requirements being released through valve 25.
