Abstract: 1,231,987. Motor vehicle transmissions and brakes. GENERAL MOTORS CORP. 26 Feb., 1970 [10 March, 1969], No. 9265/70. Heading B7A. [Also in Division F2] A separating friction clutch is arranged to connect the impeller 19 of a torque converter 15 to its driving housing 17 fast with a flywheel 5, and comprises an annular friction plate 25 applied to the annular end face of the flywheel to engage the clutch by an annular hydraulic piston 31 rotating with the housing and defining a clutch apply chamber 37 therewith, hydraulic pressure in the converter working circuit disengaging the clutch on removing the apply signal. As shown, the converter turbine 21 is splined on a shaft 49 moved axially through linkwork 63-65 to engage a vehicle forward/ reverse gear comprising forward and reverse gears 53, 55 meshing an output gear 79 directly and through an idler respectively. The shaft 49 carries a positive clutch element 67 adapted to engage internally of either gear 53 or 55, and the linkwork also controls a valve 45 controlling the supply of hydraulic fluid to the clutch. The clutch is thus disengaged for forward/reverse shifts. The output gear 79 forms the housing for a differential gear 81 having a pair of output axle shafts 83, 85 rotatably journalled in the housing and having a pair of intermeshing pinions 87, 89 to allow differential action. A disc-type vehicle brake 103 acts directly on the wheel 79, the brake pads 95 being continuously applied by light springs 99, and the parasitic drag being reduced by a lubricant film maintained on both faces of the gear-wheel 79. The axle shaft 85 passes through a hollow engine cam-shaft 91.

[Also in Division C1] A benificiated nickel ore is obtained from nickeliferous boulders having nickel concentrations that decrease progressively inwardly from the surface thereof by providing a comminuting zone, e.g. tumbling mill 10, (Fig. 5), forming a body of said boulders therein, and tumbling the boulders in rubbing contact with each other to abrade material of relatively high nickel concentration from the boulders to form a comminuted product 14 and uncomminuted reject cores 15 of relatively low grade, the tumbling being controlled to effect a continuous and gradual abrasion of the boulders, and minimise breakage if the cores, fresh boulders 12 being provided through inlet 11 to displace the reject cores 15 and the product 14, the degree of upgrading of the product being controlled by controlling the amount of abrasion of the boulders. Boulders are indicated in the specification as being ore of particle size greater than 1 inch. The ore may be in the form of completely or partially serpentinised boulders. The reject cores and the upgraded product may be discharged together, e.g. through outlet 13 from the comminution zone being separated, e.g. by trommel 16, on discharge. In alternative embodiments (Figs. 6 and 7) shown, at least a portion of the upgraded product may be removed peripherally from the comminution zone by means of peripheral discharge grates 17 and 28, spaced at 90‹ around the periphery of the drum. The rate of abrasion of the boulders may be regulated by the feedrate to the mill and the speed of rotation of the mill which may be about 60% of its critical speed.

Abstract: 1,238,085. Film processing apparatus. OPTISCHE INDUSTRIE "DE OUDE DELFT" N.V., June 18, 1969 [June 28, 1968], No.30853/69. Heading G2A. A film processing tank 1 has a narrow neck portion 3 and a wider lower portion, the film passing round the lower end of an arm 11 which pivots about a pin 12 in a reciprocating movement so as to agitate the liquid in the tank. The pin 12 is itself secured at the lower end of a fixed arm 10 integral with a cover 9 fitting on to the neck portion 3. The film passes from supply spool 27 between rollers 4, 13 and then down into the tank, round a roller 42 at the lower end of arm 11, and out again between rollers 4<SP>1</SP>, 13<SP>1</SP>. It may then pass into a washing tank 2, and is taken up on a spool 35. To diminish evaporation losses, a cooler 8 surrounds the neck 3. The reciprocating mechanism is shown more clearly in Fig.2. A lever 14 is pivoted on a shaft 15 extending from the fixed arm 10. A drive from a motor 17 is transmitted through an eccentric 18 and a linkage system to the upper end of lever 14, which protrudes through a slot 16 in cover 9. The lower end of lever 14 carries a pin (23), Fig.3 (not shown) which slides in a groove 24 in arm 11. Thus as a reciprocating movement is imparted to the upper end of arm 11, the corresponding movement of the lower end causes arm 11 to execute a reciprocating rotatary movement about pin 12. Thus the film strip passing round arm 11 is itself caused to agitate the liquid in the tank.

Abstract: 1,238,390. Automatic speed control. GRUNDIG E.M.V. ELEKTRO-MECHANISCHE VERSUCHSANSTALT INH. MAX GRUNDIG. Dec. 19, 1969 [Dec.20, 1968], No.62049/69. Heading G3R. In magnetic recording and playback apparatus, the speed of rotating magnetic heads is controlled by pulses from different sources. One source is preferred in that it is employed if its pulses are present, and if its pulses are absent, control is automatically switched to another source. In the system shown, a unit 1 supplies the headwheel motor of a video tape recorder and is controlled by a phase comparator 2 which receives control pulses by way of a relay contact 10 and pulses from the motor shaft through a device 3. In the position shown, corresponding to 'record', a separator 6 filters vertical blanking pulses from the video signal, and these pulses actuate a rectifier device 9 to maintain the contact 10 closed. If the apparatus is stopped, the blanking pulses disappear and the contact 10 is automatically released so that the comparator 2 receives mains synchronizing pulses through a shaping circuit 8. Thus the head-wheel never runs uncontrolled and can be rapidly re-synchronized when further recording or playback is desired.

Abstract: 1,266,804. Fluid regulation. GENERAL ELECTRIC CO. Feb. 10, 1970 [March 6, 1969], No.6205/70. Heading G3H. A constant frequency fluid oscillator, which is insensitive to changes in the purity and pressure of the fluid, comprises a vane which is anchored to a base 10 by a torisonal spring 56 and has one portion 24 thereof formed with flat end surfaces 20, 22 and its other portion 26 provided with a supply passage leading to a jet nozzle 58, a fluid amplifier 36 having an input power nozzle 38 and two receivers 40, 42, a pair of driving ports 16, 18 formed in two upstanding base projections 78, 80, and a pressure source 44. In the absence of pressure, the vane orientates with respect to one of two jet receivers 12, 14 which are formed in the base and which lead to the amplifier 36. Subsequently, upon pressure being supplied through jet 58, the one of the jet receivers 12, 14 is  pressurized to a greater extent than the other as a result of which the amplifier input is deflected to one of the amplifier receivers 40, 42. Consequent to the pressure imbalance of the amplifier receivers 40, 42, the driving ports are placed in a similar pressure imbalance by virtue of the connections 50 and 52, and hence the vane is caused to turn in a direction to supply the other of the two jet receivers 12, 14. Such changeover switches the amplifier to its other state and reverses the pressure imbalance between the driving ports 16, 18 causing the vane to return to its original state. The process is automatically repeated as long as the pressure source 44 is active.
