Title: Tire and wheel alignment apparatus
Inventor: LAWSON LAWRENCE JAMES
IPC: B60C25/00
Filed: 1982-08-03
Abstract: Apparatus (21) for aligning a tire on a wheel with the wheel, to match a high spot on the tire with a low spot on the wheel or vice-versa, comprises means for locating one of the wheel and tire in a desired position, and means for holding said one of the wheel and tire against rotation while rotating the other of the wheel and tire, rotation of said other of the wheel and tire being halted when it is in the required position. In the illustrated apparatus a device 25 with tire engaging rollers 65 initially centres a wheel and tire assembly over a chuck 36 which grips the wheel. The chuck is then raised bringing the tire and wheel rim into contact with respective rollers 104,105 of a sensing unit 26, roller 104 forcing the upper tire bead away from the rim. Thereafter the chuck rotates the tire and wheel with a sensor of the unit 26 senses a mark on the tire (indicating e.g. a high spot), whereupon device 24 is actuated so that wedges 94 lift the lower tire bead from the rim and halt the tire. Rotation of the wheel then continues until automatically stopped by an appropriate sensor of the unit 26 sensing a marking (e.g. low spot) on the wheel. <IMAGE>
Patent GB-828584-A (GB)
Abstract: 828,584. Cash registers. NATIONAL CASH REGISTER CO. March 5, 1958 [April 2, 1957], No. 7027/58. Class 106 (1). A cash register has a line of interspersed totalizers shiftable from a normal position by depression of any one of a set of control keys to align a corresponding totalizer with the differential actuators, the shift being in one direction or the other depending on which control key is depressed, and the totalizer line being restored to its normal position during the ensuing machine cycle when the depressed control key is released. In the cash register described, nine totalizers are interspersed on the No. 2 line 43, and in the normal position of the line, the centre totalizer is aligned with the actuator 62. The totalizer wheels are adjustably assembled on a rod 167 movable in side frames to engage and disengage the selected totalizer and also longitudinally for selection purposes. When a totalizer is engaged an aligner bar 178 engages in a comb plate 180. The selection movement is effected by a sector 166 which engages rack teeth on the rod and which is driven through bevel gearing 163, 164 by a sector 156 differentially positioned by the action of studs, e.g. 152, in the control key stems on cam slots of the sector. On depression of a control key, a detent bar moves upwardly to latch the key and a lever 284 coupled to the detent bar is latched by clockwise rocking of a lever 286 on the usual machine release shaft 65, so as to hold the key in depressed position. When the sector 156 is rocked from normal position, a cam slot 183 therein acts on a roller 184 to rock an arm clockwise. This tensions a spring 191 and through a spring 187 rocks an arm 186 into the path of a stud 192 in the lever 286. When the machine release shaft is returned counter-clockwise, stud 192 rocks the arm 186 to tension the spring 187 further. The lever 286 also engages a roller 287 to restore the lever 284 and detent bar so as to release the depressed control key. The sector 156 is then carried by the arm 185 under the action of both springs 187, 191, back to its normal position, this action being assisted in some cases by the action of the key stud in its cam slot.

Title: Telecommunication system
Inventor: REES FREDERICK HENRY
IPC: H04M7/14
Filed: 1985-10-02
Abstract: The public telephone network is being enhanced by the inclusion of digital exchanges in what was hitherto a mainly analogue network, with digital links between the digital exchanges and also (with suitable conversion) between analogue and digital exchanges. In addition, analogue PABX's are being replaced by digital PABX's, which raises a number of problems. To deal with one problem a concentrator-expander (2,4) pair can be used, which concentrates a number of digital links (1) on to a set (3), less in number of links to an expander (4) at which the links (3) are expanded to a set of links (6) equal in number and corresponding to the first links which give access to a digital exchange (5). Signalling uses some of the time slots on the concentrator-expander links (3), so that although communication is channel-concentrated, signalling is not. Such a concentrator-expander pair, or pair gain arrangement, is system-independent. Digital PABX's, and also digital lines thus added in place of analogue PABX's and lines are parented on digital public exchanges, but also have access to public analogue exchanges. Such digital PABX's and lines retain their old numbers for incoming analogue calls, but have new numbers for incoming calls using digital facilities. Outgoing calls use new digital access via a multiplexer (12). <IMAGE>
