Title: Steering device on a transport truck
IPC: B62D7/14
Filed: 1975-04-07
Abstract: 1500145 Steering systems MASCHINENFABRIK RIETER AG 7 April 1975 [8 April 1974] 14094/75 Heading B7H A load transport truck has at least three castor rollers 5, 6, 7 of which rollers 6, 7 respectively adjacent the front and rear of the truck are connectable to and disconnectable from steering gear which causes them to turn in opposite senses, the remainder of the rollers being freely rotatable castors. In a first embodiment, Fig. 1, rollers 6 and 7 respectively mount fixed and rotatable sprockets 9, 14 and a sprocket 20 and steering lever 21 are rotatably mounted on a pin 19. Sprockets 14 and 20 may be fixed relative to roller 7 and lever 21 to transfer steering signals from lever 21 to rollers 6, 7 through pivoting levers (16, 23) (Fig. not shown) respectively mounted on the roller 7 and lever 21 and which engage slots (151, 221) in the sprocket hubs. The pivoting levers are engaged by rings 32 surrounding roller 7 and pin 19 which form part of a linkage 31 controlled by a lever 26. Vertical movement of the rings effects engagement and disengagement of the pivoting levers. In a second embodiment, Fig. 5, the rollers 6, 7 each mount fixed sprockets which are engaged by a toothed rack 61. The rack is mounted on a pin 36 and carries springs which abut the pin and stops 39, 40 on the rack. The rack may be moved out of engagement with the sprockets by a push lever 62.

Title: Data transfer apparatus
IPC: H04L29/08
Filed: 1973-03-23
Abstract: 1394646 Data transfer system HEWLETT-PACKARD CO 23 March 1973 [3 April 1972] 14177/73 Heading G4H A data transfer system comprises a source 60 operating asynchronously with a plurality of receivers 62, 64, ... at a data transfer rate limited only by the operating rates of the source and the receivers. The receivers include displays (e.g. glow-discharge numerical indicators), printers, tape punchers &c. which have different response times: the data source 60 thus includes a control circuit 114 which is responsive (via distributor gates 112, 110), only to "ready for data" (RFD) and "data accepted" (DAC) signals from all the receivers. Initially signal DAC goes."low" to step a counter 76 whose output causes a multiplexer 74 to place the contents of a register 66 on to lines 78; signals DAC, RFD set a flip-flop 120-122 to produce a "data valid" signal DAV after a delay 116 which allows transients, reflections &c. to die away. In receiver 62, DAV is delayed at 113, then passes through a gate 111 to clock the data on 78 into a D-type flip-flop 102 forming the first stage of a shift-register. Signal DAV is delayed again at 117 and a third time at 119 in order to produce in turn signals DAC and RFD for that receiver, these signals being fed to gates 110, 112. When all the receivers have accepted the data from register 66, gate 110 outputs a signal on line 83 which steps counter 76 to cause multiplexer 74 to place the contents of register 68 on lines 78 (signal DAV being removed). As before, signal RFD is output from gate 112 when all the receivers are ready (e.g. when a printer motor has attained the correct speed), and signal DAV indicates that the data on lines 78 is ready to be clocked into the receiver shift-registers, the data from register 66 being shifted to flip-flop 104. The above process is repeated until the contents of registers 66-72 is stored in register 102-108, whereupon the next output from counter 76 causes fresh data to be fed to the registers. Gates 110, 112 may be transistor AND gates (Fig. 3, not shown); if any of the receivers are not on-line (due to, e.g. a cable disconnect or a power failure), the signals RFD and DAC for that receiver both assume a signal level which allows the processing to continue as if the receiver was present and accepting data normally, so that the system will not be delayed by the absence of an output from gates 110, 112. The data source control circuit may also incorporate means 126 for monitoring the RFD and DAC signals to detect the above condition.

Abstract: 1,177,493. Coating apparatus. BOSTIK Ltd. 30 March, 1967 [31 March, 1966], No. 14331/ 66. Heading B2L. Apparatus for applying adhesive composition to a workpiece W comprises a casing 22 provided with a generally semi-cylindrical recess 24; an applying wheel 20 having a circumferential surface 21 provided with at least one indentation 69 and mounted in the recess 24 for rotation about an axis eccentrically of the recess, the surface of the wheel bounding a wedge-shaped cavity 23 and having a portion protruding from the recess; a doctor bar 26 engaging the surface of the applying wheel adjacent a locality 79 of the cavity 23 where the applying wheel surface leaves the recess; a supplying device 15 to supply adhesive composition to the cavity and a means located within the cavity and responsive to the amount of adhesive composition in the cavity to control operation of the supply device. The latter means is preferably a vane 52 movement of which operates a micro-switch 62 Which controls operation of a clutch C driving wheels 42, 44 for feeding solid adhesive rod R to the casing 22. Casing 22 is heated so that the adhesive melts and flows via a bore 30 and groove 70 in one face of recess 23 to the locality 79. A further small groove 71 feeds adhesive to the bearing bush 77 for lubrication purposes. In use, rotation of the wheel 20 tends to draw adhesive along the groove 70 at a rate in excess of that at which it is supplied from the supplying device so that the adhesive in locality 79 is at a higher pressure than atmospheric. The adhesive is picked up by the wheel 20 from the locality 79 and by adjustment of the bar 26 the surface of the Wheel is wiped free of excess adhesive. The adhesive in the indentations 79 however expands on being released from the recess and becomes applied to the workpiece W in a pattern corresponding to that of the indentations in the wheel. A stringer roll 28 and a co-operating doctor bar 29 clear the wheel 20 from any adhesive remaining thereon.
