Title: Modulator for an anti-locking hydraulic braking system
IPC: B60T8/42
Filed: 1974-11-12
Abstract: 1449949 Aritiskid braking systems USTAV PRO VYZKUM MOTOROVYCH VOZIDEL 12 Nov 1974 [13 Nov 1973] 48955/74 Heading F2F A modulator for an antiskid braking system comprises a body 10 with a chamber therein, a balance piston 11 within the chamber, a first control valve 14 operated in dependence on wheel lock to permit pressure to be applied to one side of the piston 11 from an auxiliary hydraulic supply 8 ot to allow relief of pressure, and a second control valve having a piston 12 and which permits passage of fluid from a wheel cylinder to the other side of piston 11 or disconnects the said passage when the fluid pressure from the auxiliary supply falls below a predetermined pressure level. When skidding occurs a valve 4 closes connection between the wheel cylinder 5 and the master cylinder 1 and slide valve 14 is moved by a signal against a spring 16 to connect a control space A to a reservoir 9 allowing loss of pressure in the space and movement of piston 11 to increase the volume of space B to relieve braking pressure. If there is a loss of pressure in accumulator 8 piston 12 is moved by a spring 17 to disconnect space B from cylinder 5 the system then acting as a normal system without antiskid control.

Title: Rotary filling machine comprising a washing device
IPC: B67C3/00
Filed: 1975-11-28
Abstract: 1488428 Rotary filling machines SHIBUYA KOGYO CO Ltd 28 Nov 1975 [30 Nov 1974 13 May 1975 27 May 1975 10 June 1975] 49042/75 Heading B8T Washing liquid pipes 21, initially in positions not obstructing the movement of bottles on a conveyer table 7<SP>1</SP> or tables 7, are moved to positions vertically below filling nozzles 11 and a vertical movement mechanism brings nines 21 and nozzles 11 into contact so as to force open valves in the nozzles and allow the passage of the rotary filling machine to be washed. In Fig. 2, a conveyer table 7 is provided for each bottle and, as the tables are rotated around a shaft 9, they are raised in turn by a cam 8 to bring the bottle necks into contact with nozzles 11 for filling. After filling, pipes 20 carrying pipes 21, are moved radially outwardly, with respect to brackets 19 on a support ring 17, by cylinder devices 22 and, since part 9b of shaft 9 slides on part 9a, nozzles 11, attached to a tank 10 carried by part 9b, are moved vertically downwardly with respect to pipes 21 attached to part 9a by a motor which rotates worm-wheels 29 and hence turns screws 25 in holes 24. Alternative arrangements provide for vertical movement of pipes 21, rather than nozzles 11, by a similar screw arrangement or cylinder devices. In Fig. 14, a single conveyer table 7<SP>1</SP> is provided and nozzles 11 are moved vertically by rollers 75 following a cam 81. Pipes 21 are similarly moved by rollers 86 following a cam 87 and vertical movement of the tank, with all the nozzles maintained at their uneven levels, occurs by operating screws 25 since cam 81 is slidably mounted. Alternatively, the pipes 21 are moved vertically by cylinder devices. If the pipes 21 are on the same horizontal level, nozzles 11 may be returned to one level by downward movement thereof out of contact with the cam 81 or upward movement of the cam 81 by cylinder devices. Alternatively, the pipes are moved vertically by cylinder devices by varying amounts to match the uneven levels of the nozzles. The cylinder devices 22 may be replaced by arranging the nozzles 21 on arms 68, which are pivoted by shafts 67 to a plate 50 which can be rotated relative to a plate 59 having radial cam grooves for cam followers 69 or the arms, whereby the nozzles 21 can be moved into and out of the positions occupied by bottles B (Fig. 8). A similar arrangement has nozzles on arms which slide in radial grooves in plate 59 as cam followers move in arcuate grooves in a member rotatable with respect to the plate. A circular path for washing liquid is provided since a pipe 43 from tank 10 is connected to pipes 21.

During normal filtration liquid received at 50 in a tank 20 is pumped at 70 to the foot of a filter vessel 22. Filtrate emerging from the interior of mesh filter tubes 56 is discharged at 76 to a clear-liquid tank 26, whence most of it is pumped to use, whilst the remainder is pumped at 182 back to tank 20. On clogging of the filter tubes, a pressure-sensitive switch 263 closes, whereupon the following sequence of operations takes place. (a) Pump 182 is stopped; (b) after a timed interval a motor 218 is started in order to move filter paper 191 from a reel (seen at the left of the Figure) across a mesh screen (not shown) in a sludge disposal unit 24, the filter paper, together with residue from a previous filtering stage, eventually being discharged where shown just beneath the motor 218; (c) after a further timed interval, motor 218 is stopped and simultaneously a motor 132 for feeding powdered filter aid at 140 to chamber 142 is started, inlet and outlet valves (only one, 82, being shown) to filter vessel 22 are closed, a drain valve 86 is opened, and a compressed-air valve 124 is opened to force liquid, residue and filter aid from vessel 22 on to filter paper 191 in sludge disposal unit 24; (d) after a further timed interval, the valves are restored; (e) after a further timed interval the filter aid motor 132 is stopped and pump 182 re-started. Pump 182, by operation of ejector 240, extracts liquid through pipe 180 from beneath the mesh screen in sludge disposal unit 24, and when the pressure in this region falls, a pressuresensitive switch closes, whereupon the following sequence takes place, (a) Pump 182 is stopped; (b) after a timed interval motor 218 is started; (c) after a further timed interval motor 218 is stopped, pump 182 is re-started and normal filtration is resumed.

Title: Improvements in or relating to the measurement of maximum temperatures

Filed: 1967-11-07
Abstract: 1,202,280. Resistors. INTERNATIONAL BUSINESS MACHINES CORP. 7 Nov., 1967 [29 Dec., 1966], No. 50488/67. Heading H1S. [Also in Divisions C7 and G1] The maximum surface temperature attained by an article during a manufacturing process is measured by means of a resistor of which the resistance and temperature coefficient of resistance are changed permanently in dependence upon the maximum temperature to which the resistor is subjected, but independent of the length of time for which it is subjected to that temperature, which may therefore be determined by subsequent measurements of resistance or temperature coefficient of resistance of the resistor. A maximum surface temperature device 10, Fig. 3, comprises a silicon or molybdenum substrate 12, an insulating silicon dioxide layer 13, a thin film resistor 14 of a mixture of specified proportions of chromium and silicon monoxide, conductive layers 15, 16 and lead wires 18. A protective coating 17 shields the film from reactive gases. In use, the device measures the maximum surface temperature attained by a semi-conductor wafer (50), Figs. 4, 5, 6 (not shown), which is heated in an R.F. sputtering apparatus (see Heading C7A), a layer of gallium or a gallium indiumalloy being interposed between the substrate and the wafer to provide good thermal contact. Fig. 7 shows that the residual resistance of each of four similar devices, having a resistor film of 80 atomic per cent chromium and 20 atomic per cent silicon monoxide, was 63% of the initial resistance, for a maximum temperature of 500 C., the time taken to reach that temperature being different in each case. Fig. 8 illustrates the variation of residual resistance as a function of atomic percentage content of silicon monoxide with maximum temperature as a parameter. Fig. 9 illustrates the abrupt changes in three temperature coefficient of resistance characteristics, the temperature in brackets being the actual temperature maximum in each case, while that without refers to the point of change on the characteristic in each case. Figs. 1 and 2 (not shown) illustrate another embodiment of the device in which the substrate (11) is of silicon there being no protective coating on the resistive film.
