Title: Process and apparatus for establishing a running centre for  a wheel
IPC: B23B41/00
Filed: 1972-11-04
Abstract: 1438640 Gauging BRITISH LEYLAND UK Ltd 1 Nov 1973 [4 Nov 1972] 50913/72 Heading B3B [Also in Division G3] The optimum running centre of a vehicle wheel 11 is determined by detecting radial run-out during a rotation of the wheel, Fourier analysing the result, and establishing the optimum centre by minimizing the eccentricity, or first harmonic component of the results. In response to the analysis in computer 23, servo positioning system 22 moves table 17 supporting back plate 13 itself supporting pressed steel wheel 11 until the desired running centre is co-axial with axis 20 of rotation of boring tool 21. Advance of head 18 as spindle 15 is withdrawn enables the optimum centre to be bored out. A pair 24, 25 of displacement probes contact wheel bead seats 26, 27. Signals are thus produced corresponding to the amount by which each probe is displaced from a datum position and the results are averaged to provide the resultant for Fourier analysis. Only a single probe need be used. Table 17 is displaceable in a plane perpendicular to axis 20, or, if the wheel is rotated prior to boring so that the desired centre lies on a given line, only one degree of table freedom need be provided.

Abstract: 1,093,728. Synchronizing oscillators. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Dec. 2, 1965 [Dec. 4, 1964], No. 51169/65. Heading H3A. A data transmission system having means for synchronizing the receiver clock with the received data includes a magnetic store, e.g. a transfluxor, which controls the phase of the clock, the flux in the core being related to any phase difference between the data and the clock. In a first embodiment, Fig. 5 (not shown), the square wave pulses (2), Fig. 6 (not shown), from the clock are rounded (3) and added to the delayed and differentiated data signal. The resultant waveform (4) feeds a threshold device which produces constant amplitude pulses (5) of a width related to the phase difference, these being fed to the transfluxor. The undelayed data is also differentiated to give pulses (7) which reset the transfluxor prior to each adjustment of the clock by the transfluxor output (8). In a second embodiment, Figs. 7 and 8 (neither shown), the clock is adjustable forward or backward in phase. The clock provides pulse trains (2, 3) 180 degrees out of phase which open gates (14, 15) alternately to allow the output (5) from the threshold device to pass to one or the other input winding of the transfluxor to adjust the flux level (8).

Title: Tyre bead seating and inflating
IPC: B60C25/14
Filed: 1972-11-14
Abstract: 1388608 Seating and inflating tyres on rims COATS CO Inc 14 Nov 1972 [3 March 1972] 52518/72 Heading B7C A tyre bead seating and inflation apparatus mounted on a tyre changing stand 10 comprises housings 32, 36 attached to the stand, an arcuate air tube 28 attached to the stand and provided with apertures 60, a compressed air tank 38, a first air line 82, 110 including a normally closed valve 102 and communicating the tank with the air tube 28, and a further air line 106, 96, 100 extending from the first air line at point 104 upstream of valve 102, and including a normally closed valve 108 and a manually operable air release valve 90, to a tyre inflation valve attachment 44. The valves 102, 108, which are mounted in the housing 32, are controlled by a foot pedal 34. A pressure gauge 40 mounted in housing 36 indicates the air pressure in a tyre being inflated. In operation, with the tank 38 connected via a pressure line (not shown) to a compressor, a wheel 50 with a loosely fitted tyre 54 on the stand and attachment 44 connected to the tyre inflation valve 56, depression of the pedal 34 to the third position (Fig. 5) opens both the valves 102 and 108 to permit simultaneous supply of air to the air tube 28 and the inflation valve 56 thus resulting in seating of the beads and partial inflation of the tyre. Upon return of the pedal to the second position, the valve 102 is returned to its normally closed condition so that air is now supplied only to the tyre via the inflation valve 56. Should the tyre be overinflated, actuation of the air release valve 90, when the pedal is released, will permit the air pressure in the tyre to drop to its required value.

A method of adhering metal roll leaf to the surface of an article comprises pressing on to the surface a layer of the roll leaf carrying a coating of adhesive, with the adhesive in contact with the surface, the layer being at ambient temperature, applying a pulse of heat to the layer while maintaining pressure thereon, permitting the layer to cool while maintaining pressure thereon and then removing the pressure. Metal roll leaf comprises a carrier strip of plastics covered on one side with a vapour deposited coating or foil of metal which is capable of release from the carrier. Apparatus for adhering metal roll leaf to the surface of an article comprises a mechanism for positioning a new area of the roll leaf adjacent the surface of each new article, first means for pressing on to the surface a layer of the roll leaf at ambient temperature, second means for applying a pulse of heat to the layer while maintaining pressure thereon, and third means for cooling the second means-to ambient temperature before treating each new article. The article may be formed of thermoplastic or thermosetting synthetic resin, or of a non-resinous material and may be polystyrene, acrylonitrile-butadiene-styrene copolymer. As shown in Fig. 1 a support nest 11 of a slightly yieldable heat-resistant material such as silicone rubber is mounted on base 13 and carries an article 16 such as a moulded plastic camera part having an upwardly raised design 17 upon which metal roll leaf is to be applied. A long strip 19. of metal roll leaf is positioned horizontally above the nest 11 with its adhesive coated side down. The strip 19 passes from supply roll 21 to a driven wind-up roll 23 which is indexed after each actuation of the apparatus to wind up the foil which escapes application to the article 15. A vertically reciprocable plunger 25 having on its lower end a water cooled head 27 carries a sheet 29 of electrically insulating material such as paper covered by a thin metal sheet or strip 31 for pressing the foil against the design 17. The sheet 31 may be formed of chrome-nickel stainless steel, and it has electrical connections for heating current. The plunger 25 can be reciprocated up and down, e.g. pneumatically, hydraulically, or by a weight moved by gravity under the damping restraint of a pneumatic piston which is then actuated upwardly by compressed air. The heater strip 31 has a block 26 near one end held in a clamp 28 on the side of the head 27. A second block 30 near the opposite end is held in a second drum 32 which is spring-pressed around a fulcrum 36 on the head 27 so as to take up the slack when the strip 31 expands during heating. Automatic control means for actuating the plunger and the heating of sheet 31 in timed relationship are described and illustrated.
