A hollow conical drum 150 compresses the hay &c. axially towards the bite between the wheels, and the compressed material is forced radially inwardly through the dies of both wheels and falls on to the conveyer 32. The outlet ends of the die openings are adjustable by a bendable portion 198 on the wheel and screws 196.

Abstract: 1,167,968. Printing apparatus; damping apparatus. ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER A.G. 31 Aug., 1967 [9 Sept., 1966], No. 39855/67. Heading B6C. A damping device for an offset rotary press having provision for interrupting the supply of moisture to the forme rollers which are engageable with the printing plate comprises an adjustable counting means which counts operational cycles of the press and which permits the engagement of the forme rollers with the plate after a selected number of press cycles after the supply of moisture has started. As shown, Fig. 1, blanket cylinder 3 is journalled in eccentric bearings 7. Current supplied to solenoid 8 " throws-on " the blanket cylinder whilst current supplied to solenoid 9 " throws-off " the cylinder through appropriate rotation of the bearings 7. The damping device 6, Fig. 2, comprises a ductor roller 15 driven by a variable speed electric motor 16. A messenger roller 19 on a shaft 45 carries two two-arm levers 20 each of which supports on one arm an adjustable moisture applying forme roller 21 journalled in eccentric bushes 21. A spring 23 associated with each lever 20 urges the roller 21 into "throw-off" position. To "throw-on" the roller a solenoid 25 is energized. A set screw 26 serves to adjust the maximum pressure with which roller 21 can engage plate cylinder 2. An adjustable counter 31 (not shown) is fed by a switch 13, Fig. 1, operated by a nose 12 rotating with the impression cylinder 4 and after a predetermined number of cycles a visual or audible signal is energized. The roller 21, sufficiently dampened, is then " thrown-on the cylinder 2 either manually or automatically. When the blanket cylinder is " thrown-off " the roller 21 remains in contact with the plate cylinder 2 but supplies a reduced amount of moisture as the speed of the motor 16 is automatically reduced.

Abstract: 1,091,656. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Sept. 13, 1966, No. 40876/66. Addition to 1,013,424. Heading H1K. The invention of the main patent, which relates to bevelling the surface of a body on the higher resistivity side of a PN junction to increase the breakdown voltage, is applied to a junction transistor the collector region being of higher resistivity than the base region which has a greater thickness at the periphery of the body than below the emitter region which is inset in the base region. The transistor is produced by diffusing an N<SP>+</SP> type region into the lower face of a high resistivity N-type silicon wafer and etching or air abrading the top face to form a mesa, Fig. 10 (not shown). Gallium is diffused into the shaped surface to produce a thick P<SP>+</SP> type layer, Fig. 11 (not shown). This surface is then lapped flat to produce a wafer having a thick annular P<SP>+</SP> type region inside which the original N-type region is exposed, Fig. 12 (not shown), and gallium and phosphorus are diffused into this exposed region using an oxide masking technique to produce a P-type base region with an inset N<SP>+</SP> type emitter region, Fig. 13 (not shown). The edge of the wafer is then bevelled by air abrasion, Fig. 14. The N <SP>+</SP> type collector layer may be produced by epitaxy or may be omitted.

Abstract: 1,154,248. Fluid pressure brakes. AUTOMOTIVE PRODUCTS CO. Ltd. 16 Oct., 1967 [16 Sept., 1966], No. 41533/66. Headings F2E and F2F. An anti-lock means comprises: a first rotatable member driven by the running wheels of a vehicle; a second rotatable member similarly driven at a lower speed but so coupled that on a reduction of speed of the wheels it continues to rotate at the same speed; deceleration responsive means to apply a braking force to the second member, varying with the deceleration; means for comparing the speeds of the two members; and means operating at a predetermined relative speed to control the braking of the vehicle. A shaft 6 is driven by the transmission, and is surrounded by a shaft 7 driven by the transmission at a lower speed in the opposite direction, and carrying a flywheel 10 coupled to it via a clutch (not shown). The shaft 6 and flywheel 10 are coupled via a planet wheel assembly 34, 36, 37, 38, so that during unbraked running the planet wheel 36 rotates in one direction to actuate a two position switch 42, 44 to one of its positions. During braking, the shaft 6 slows down until its speed drops below that of the flywheel whereupon the planet wheel 36 rotates in the other direction to set the switch to its other position. The switch controls an electrically operated valve 97, Fig. 4, in the brake circuit. Retardation of the vehicle causes a pendulum Fig. 1 (not shown), to rotate a ring 13 sufficiently to bring openings 31, 32 into alignment and connect space 15 to a vacuum source thus providing braking for flywheel 10. With valve 97, Fig. 4, in one position both sides of diaphragm 95 are connected to vacuum and valve 108 in the brake feed 105, 106 is open, in the other position the upper side of the diaphragm is connected to atmosphere and the valve 108 is closed. On re-opening some air is allowed to leak into the upper chamber, so that the valves open to a lesser extent, thus applying the brakes at a reduced pressure. In an alternative arrangement, Fig. 3 (not shown), the two shafts are driven differentially by gearing within the casing and the switch (71, 72) is operated by a cam surface (66).
