Filed: 1974-12-20
Abstract: 1528126 Mounting brake discs GIRLING Ltd 31 Oct 1975 [20 Dec 1974] 55217/74 Heading F2E A braking ring element is circumferentially keyed to a rotor and radially inward and outward movement is prevented by respective pairs of circumferentially spaced abutments positioned so that there is substantially no movement of the element into or out of engagement with the abutments on thermal expansion or contraction. As shown in Figs. 2 and 3 each disc segment 1, 1<SP>1</SP> is keyed against circumferential movement by rectangular projections 6 secured to the wheel 2 and received in a complementary recess in the disc. Each disc abuts the undercut rim of the wheel at a pair of circumferentially spaced points 3 and is supported at its inner periphery by a pair of abutments 4 formed as adjustable wedges. The latter may be replaced by springs (Figs. 4, 5, and 8, not shown) and circumferential keying may be effected by a block secured to the disc and received in a cut-out, portion of the wheel rim.

Filed: 1969-11-11
Abstract: 1,246,375. Rolling mills. HITACHI Ltd. 11 Nov., 1969 [13 Nov., 1968], No. 55232/69. Heading B3M. A rolling mill incorporates a keeper plate 1 for maintaining a roll 30 in a desired axial position, the plate normally clamping the edge 25, Fig. 3, of a roll chock 23 against a housing 24, but being movable laterally to permit changing of the roll. The plate is of channel-shaped cross-section with one vertical edge bearing against the chock, and the other edge against a wedge 2, Fig. 2, of composite form. To remove the roll, the wedge 2 is raised by a cylinder 8, thereby allowing the plate to pivot about the washers 4 of retaining bolts 6 and to unclamp the edge 25 of the chock. The plate is then moved laterally by a further cylinder to allow removal of the chock and roll from the housing. Bolts 10 control the spacing L 1  between the plate and housing, while springs 14 urge the plate towards the housing. A similar plate may be provided for the lower roll 31 of the mill.

Abstract: 1,117,439. Gas-filled container for X-ray tube. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Dec., 1966 [15 Dec., 1965], No. 55526/66. Heading H5R. [Also in Division H1] An X-ray tube assembly comprises an X-ray tube in a closed envelope filled with sulphur hexafluoride in which the tube vessel has a coating of material such as epoxy resin lacquer, not attacked by hydrofluoric acid, the coating thickness being such that fluorine gas evolved from sulphur hexafluoride dissociation does not come into contact with the vessel. In an embodiment, the X-ray window is arranged close to the tube to reduce the formation of sulphur tetrafluoride and fluorine by the interaction of the X-rays with the sulphur hexafluoride which may be further reduced by the insertion of foam plastic impervious to sulphur hexafluoride, in the beam path.

Abstract: 1283375 Friction gearing J B BLAKE 19 April 1971 [26 Nov 1969] 57898/69 Heading F2Q A frictional drive speed reduction gear comprises an inner ground metal cylindrical surface 12 on a fixed outer member and a floating annular member 18 of a smaller diameter having an outer ground metal cylindrical surface which member 18 has a pin and slot connection 21 with an output shaft 17. Rollers 24 on a floating spindle 26 engage the member 18 and provide a radial force to hold it in frictional contact with the surface 12 when the spindle is engaged by the ramp surface 27 of a member 28 connected to an input shaft 16. Thus rotation of the shaft 16 will cause the member 18 to roll around the member 12 and produce rotation of the shaft 17 at a reduced speed. The rollers 24 may be provided on an eccentric shaft connected to the shaft 16 and be provided with a peripheral tyre. The surface 12 may have a friction lining. Other means of producing the radial pressure include rockable eccentric members on the shaft 16 provided with adjustable spring urged cam surfaces to engage a spindle 26. In an alternative arrangement the inner member is held against rotation but permitted to float while the outer member can rotate and is connected to the output shaft.

Patent GB-655334-A (GB)
Abstract: 655,334. Electric indicating systems. AUTOMATIC TOTALISATORS, Ltd. Sept. 24, 1948, No. 24973. Convention date, Sept. 24, 1947. [Class 40 (i)] [Also in Group XIX] An odds computer for a racing totalizator comprises a resistor 6 energized from a constant voltage source 9 through a contact 4, which is traversed in accordance with the grand total of wagering transactions registered by the unit 7. A second contact 5 is traversed over the resistor in accordance with the total transsactions on an individual competitor registered by the unit 8, and picks off a voltage, proportional to the odds for that competitor, which varies the anode current of a triode 10 to deflect a moving coil movement 11 in accordance with the prevailing odds and traverse a soft iron contact 13 over a potentiometer winding 14 and a contact strip 15. Coil 25 is energized at cyclic intervals to attract the contact 13 to bridge the strip and the potentiometer, which is connected in Wheatstone bridge with a second potentiometer 16 and an unbalance relay 17.

Patent GB-733195-A (GB)
Abstract: 733,195. Calculating-apparatus. VEB MECHANIK ASTRAWERKE. Oct. 31, 1952, No. 27509/52. Class 106 (1). In a calculating-machine, the, or a selected, totalizer is first engaged with one or the other of a pair of intermeshing sets of intermediate wheels according to whether addition or subtraction is to be performed, and then one set of intermediate wheels is engaged with the differential actuators. Several totalizers 1 are carried by a drum which is rotated to align the selected one with either a set of pinions 2 for addition or a set of pinions 3 constantly meshing with the pinions 2 for subtraction. The pinions 2 are rotated by actuators 4 during the return movement of the latter. The intermediate pinions 2 and 3 are mounted in a frame 10 carrying a roller 11 engaged in a cam slot of a plate 7 oscillated by the main shaft. On a further pivot 14 on the frame 10 is mounted a lever 13 having a cam slot engaged by a roller 16 on a coupling frame 15. The lever 13 is coupled to the plate 7 by a link 12. In an entry operation, the initial clockwise movement of the plate 7 does not rock the frame 10 so that the pinions 2 remain disengaged from the actuators 4 but the lever 13 is rocked so as to engage the selected totalizer 1, by moving it outwardly from the totalizer drum, with either the add pinions 2 or the subtract pinions 3. Further clockwise movement of the plate 7 maintains the engagement of the totalizer with the intermediate wheels but rocks the frames 10 and 15 clockwise as a unit to engage the pinions 2 with the actuators. After the return of the actuators, counter-clockwise movement of the plate 7 restores the frames 10 and 15 in a reverse sequence. The arrangement enables springs 6 loading transfer segments 5 to be tensioned gradually throughout the initial part of a cycle since the segments are not then in operative connection with the totalizer wheels.

Title: Air Suspension
IPC: B60G9/00
Filed: 1978-09-13
Abstract: An air suspension having improved anti-roll properties may be fitted to longitudinal chassis members (50) Fig. 2 (not shown) of a goods vehicle frame or sub-frame. Brackets 2 fitted to the chassis members pivotally support rigid trailing arms (1) which can accommodate limited movement in a vertical plane. An axle 56 is secured to the trailing arms 1 at an intermediate longitudinal position. The trailing arms extend rearward of the axle and cranked outwards with their tips 42 substantially in alignment to the wheel track. Rigid air spring mounting brackets (11) extend outwards from the chassis members (50) with their tips overlying the tips 42 of the trailing arms 1 and air springs (70) are secured between them substantially in alignment with the wheel track. Load levelling valves secured to the axle control the pressure in the air springs (70). The arrangement thereby provides a high roll resistance and a high rate of spring damping for maintaining a soft ride. <IMAGE>
