Abstract: 1,051,156. Heating chambers. F. E. G. BOURQUARD. Sept. 12, 1963, No. 36071/63. Heading F4U. To achieve and maintain a constant temperature in a fluid-tight housing 1 (drawing not shown) containing apparatus 2, the housing is placed in a thermally insulated fluid-tight chamber 3 in which the vapour pressure of water therein is maintained constant. The water is evaporated by an electrical heating element 5 immersed in the water, unstable conditions being prevented by acoustic waves generated by a tuning fork 19. Pressure is maintained constant by removing vapour by a pump 7 connected to a condenser 12 from which condensate returns under gravity to the chamber 3 through a pipe 14. Initial adjustment is made by extracting vapour through a pipe 8 then constant conditions are maintained by removing vapour through an electrically operated valve 11 and metering part 10a. An adjustable pressure switch 6 controls the element 5, valve 11 and pump 7, the element being de-energized when the pump and valve operate. If fluid is supplied to apparatus 2, it is passed through a heat exchanger 20 and coil 23 to increase temperature stability.

Abstract: 1,053,361. Making tyre bead cores. PIRELLI S.p.A. June 19, 1963 [July 9, 1962], No. 24342/63- Heading B7C. [Also in Division B8] An annular structure comprising a single or multistranded filament helically wound about an axis extending along a pitch circle, such as a tyre bead core, is made by repeatedly disposing the filament around a pitch circle which passes through a disc, which disc comprises an eyelet connected with its periphery and which rotates about its axis of symmetry, so that the filament is threaded into the eyelet each time it is disposed round the circle. Two arcuate sectors 15, 16 have a peripheral groove (26) (Fig. 2, not shown), and means 19, 24 serving to rotate them about their pivots 17, 18. The groove (26) extends almost round a pitch circle, broken by a box 47 which contains a disc (46) (Fig. 2). The disc (46) has an eyelet (49) and a crown gear engaging gears (44), (45) by which the disc is rotated. The whole is mounted for rotation about a vertical axis on a platform 5. Fig. 1 shows how wire 60 is fed into the rotating groove (26), each turn in succession dropping into the eyelet of the disc (46), which is rotated about a horizontal axis, tangential to the pitch circle, by the gear system illustrated in Figs. 2, 3, 9 (not shown). Fig. 1 shows a carriage 94, movable along guide 93, which clamps one end of the wire 60 and carries it forward to be attached to the disc (46), and also a cutter actuated by cylinder 107 (Figs. 5, 6 not shown). Fig. 3 (not shown) illustrates the arrangement for moving box 47 radially on disc 5 to make bead cores of different diameters. Figs. 4, 4a (not shown) illustrate a device for clamping one end of the wire to the disc (46) before winding begins. Wire is fed from a bobbin (61) (Fig. 5) mounted horizontally but also rotating about the vertical axis of its arm (62) to twist the wire the same way as the disc (46) will twist it. The wire is fed over a pulley 87 whose vertical position on supports (85) controls a rheostat (89<SP>1</SP>) (Fig. 7, not shown) which controls the delivery speed. During winding successive turns, sectors 15, 16 are retracted to correct for wire build up in the groove 26. On completion, the sectors are further retracted, the two ends of the wire joined, and the bead core removed. The platform 5 may carry several discs, spaced around the pitch circle, and one disc may have several eyelets to keep successive turns of wire separate. Discs need not be radial to the axis of platform 5. In place of the rotating platform 5, the disc or discs could rotate around their axes of symmetry only and the wire be fed by a rotating wire guide.

Abstract: 1,227,742. Weighing electrically and photoelectrically. A.R.V. ROBERTS. May 24, 1968, [March 1, 1967], No.9586/67. Headings G1A and G1N. [Also in Division H1] A force balance comprises a panel movable across a magnetic field, electric conductors arranged on a surface parallel to or concentric with the panel and extending through the field, means for applying a force to be measured to the panel and means for passing an electric current through the conductors so as to exert on the panel an electromagnetic force balancing the force to be measured. A weighing machine comprises a flat electrically insulated plate 10 mounted on a pivot disc 13 supported by conductive ligaments 16, 17. The ends 11, 12 of plate 10 have printed on them rectangular spiral conductors 25, 26 electrically connected in series between the ligaments 16, 17. When the weights in scale pans attached at 38 are unequal, the photo-cells 42 are unequally illuminated and the cell outputs vary the current flowing through the coils 25, 26 until the force produced by co-operation with magnets 35 balances the inequality of weights. A plurality of coils may be printed on top of each other with insulation between, or on opposite sides of the plate 10, and the plate may carry a conductive coating for eddy-current damping. In a modification, Fig. 2, (not shown) the weighing machine comprises a rectangular disc with a coil printed on it suspended vertically from four ligaments which permit vertical movement. The disc has a scale pan on top and its position is sensed by two photo-cells co-operating with a lamp through a slot in the disc. The panel may be in the form of a cylinder. The invention may be applied to the measurement of ferromagnetic, paramagnetic, diamagnetic electrostatic or surface tension forces or forces due to pressure or bombardment of particles in vacuum evaporation. The position of the plate 10 may be sensed capacitively instead of photo-electrically.

Abstract: 1,230,047. Transfer gearing. INTERNATIONAL HARVESTER CO. 7 Oct., 1969 [7 Oct., 1968], No. 49245/69. Addition to 1,141,928. Heading B7H. [Also in Division F2] The parent Specification 1,141,928 provides in a motor-vehicle having front and rear driving axles driven through a two-speed transfer case following a main change-speed gear, a control whereby both axles may be driven together in either high or low speed, the rear axle only can be driven alone in high speed, and neither axle can be driven alone in low speed. This invention achieves the same result but using a transfer shift-lever 18 which pivots about a fixed pin 25 in one plane only, thus eliminating the crossshift movement required by the corresponding lever of the parent Specification. Parallel shift-rails 21, 22 controlling front and rear axles respectively slide in a fixed block 20 under control of the lower ball end 27 of the manual shift-lever 18 secured to a V-shaped swing-link 23, pivoted at 35, 36 to the respective shift-rails. In the four-wheel drive high-speed position of Fig. 3, the rear axle shift-rail 22 is locked by an interlock drift pin 45, so that when the manual lever is moved one step forward, its ball end 27, moving right of Fig. 3, swings the link 23 about the stationary pivot 36 and shifts the front axle shift-rail 21 to a disengaged position at the right, as shown in Fig. 4, giving rear drive high speed. In this position the rear axle rail 22 is freed by the interlock pin 45 and the front axle rail 21 is prevented from further rearward movement by a second interlock pin 44. Further shift movement in the same direction causes the link 23 to swing about the pivot 35 back to the aligned position, continuing movement causing a pin 28 on the swing-link 23 to enter a fixed channel 29 and the interlock pin 44 to free the rail 21, whereafter both rails 21, 22 move together to the four-wheel drive low speed position, Fig. 5, not shown. A full return movement provides neutral of both axles, Fig. 6, not shown, before reaching the four-wheel high position of Fig. 3.
