Title: Tandem hydraulic brake actuator
IPC: F16D65/18
Filed: 1969-02-26
Abstract: 1,219,380. Brakes. SOC. ANON D.B.A. 26 Feb., 1969 [6 March, 1968], No. 10329/69. Headings F2E and F2F. A tandem hydraulic brake actuator for a split system using two separate hydraulic pressures supplied at 30, 32 comprises a main piston 14 responsive to one of the pressures and a floating piston 24 responsive to the difference between the two pressures to move also in a brake-applying direction when one system fails, and an automatic adjuster between the two pistons and means for reducing the pressure area on the outside of the floating piston. The device for adjusting the spacing of the two pistons for pad-wear, comprises a thread 38 projecting from the piston 24 and engaging a threaded sleeve 40 slightly movable in piston 14 and is rotatable against ball-bearing 44 and under the non-return effect of a coiled spring 48 to continuously take up slack. A pin 36 prevents rotation of piston 24. Under normal conditions, floating piston 24 is held back by the suction of a pin 34 in a blind hole 35, the pressure being applied at space 28 to the main piston. But if pressure at 32 fails, pressure at 30 into space 26 pushes the piston 24 against piston 14 to effect braking. Part of the active face of piston 24 may be shrouded off (Fig. 3, not shown) to hold this piston back under normal conditions without using the pin 34. In a modification, (Fig. 3, not shown), the floating piston 25 is carried on a piston-rod, 60 in Fig. 4, which extends out of the casing for mechanical hand-brake operation by cam 70. Fig. 4 shows the application to reaction frame disc brakes, the end of bore 18 is not integral but is itself a piston 22a which abuts a frame 80.

IPC: C30B13/14
Filed: 1958-04-03
Abstract: A body of material, for example silicon, to be zone melted rests during its treatment on a support which is so cooled in relation to the heating that the material immediately adjacent the support remains solid during the treatment.  As shown in Fig. 3, the support consists of spaced silica tubes 3 connected to common inlet and outlet tubes 4 for cooling fluid.  The <PICT:0915951/III/1> <PICT:0915951/III/2> tubes may also be of stainless steel, platinum, rhodium or tantalum or may be coated with chromium, rhodium, platinum or silica.  Fig. 1 shows a zone-melting apparatus in which the support is mounted within a moving silica tube 1.  A stationary radio frequency heating coil 12 is mounted outside of the tube.  A portion of the silicon body 15 is first pre-heated by a carbon ring 2 which couples with the coil 12; the ring is then pushed aside by a rod 8 and further heating of the body effected by direct coupling of the body with the coil 12.  The part of the body immediately adjacent the cooled support however is not melted.  The molten zone is caused to traverse the body by moving the tube 1 on its carriage and after the requisite number of passes the body is turned over and the part which was not previously melted is treated.  Alternatively the portion of the body which remained solid during the treatment may be removed.

Title: Phase Comparison Circuit
IPC: H04N1/36
Filed: 1967-03-08
Abstract: 1,176,206. Automatic control of speed. RANK XEROX Ltd. March 8, 1967 [March 14, 1966], No. 10889/67. Heading G3R. [Also in Division H3] A phase comparator circuit for producing signals by which the phase relationship of a slave to a master motor may be controlled comprises the arrangement of logical elements shown, by which one or the other of two bi-stable devices 19, 21, according to whether the slave lags or leads the master, is changed over from its "normal" state for a time equivalent to the magnitude of the phase displacement. Negative AND gates 16, 18 detect whether the slave or master pulses arrive first and an output from the corresponding gate switches the appropriate bi-stable device, which is afterwards reset by the following pulse. Two further negative AND gates 31, 32 and a NOR 24 resolve the ambiguity between lag or lead which would otherwise arise when slave and master pulses are exactly 180 degrees out of phase, by taking account of the immediately preceding condition. The input signals to the comparator are derived from photocells at the master and slave motors. One output terminal 22 is normally negative and is changed to positive for lagging errors and the other, 23, is normally positive and changes to negative for leading errors. They are connected to a transistor integrator circuit Fig. 3 (not shown) in which the state of charge of capacitors is varied, so producing a voltage corresponding to phase error, which is used to vary the frequency of a multi-vibrator whose amplified output powers the slave motor, which is preferably a synchronous machine, e.g. in a facsimile receiver.
