Title: Device for the automatic or manual selection of the ratio of a gearbox on a motor vehicle
IPC: B60W50/08
Filed: 1975-03-24
Abstract: 1511721 Change-speed control AUTOMOBILES M BERLIET 24 March 1975 [26 March 1974] 12111/75 Heading F2D Automatic or manual ratio shifts in a motor vehicle transmission are subject to control by means responsive to vehicle speed in order to keep the speed of the vehicle engine within predetermined upper and lower limits. A signal V v  varying in frequency with vehicle speed and monitored by a failure warning device 20, 10 is converted at 11 to a speed dependent voltage which is applied to a tapped potentiometer and logic circuit 9, 8 delivering output codes which define the lowest and highest ratios that may be employed at any vehicle speed in order that engine speed may remain within the predetermined limits. These codes are fed to a display device 7 indicating the permissible ratios, to a manually operable ratio selector 2, and to highest and lowest permissible ratio selection circuits 5, 6. An output line 24 between the selector 2 and an AND gate 3 carries no signal when the selector is positioned for manual selection so that no signals from the circuits 5, 6 are transmitted through an AND gate 3. In these circumstances a signal to establish a manually selected ratio is transmitted to a line 25 and thence through an OR gate 4 to a ratio establishing line 26 only if the selected ratio is one of the permitted ratios of which the codes are transmitted by line 28 from the circuit 8 to the selector 2. When the selector is positioned for automatic operation no signal is present in the line 25 but a signal is transmitted to the line 24. If, in this case, a kickdown switch 12 is operated a memory device Q will emit a signal through a line 22 to an AND gate 13 so that the code corresponding to the lowest permissible ratio is transmitted from the circuit 6 to the ratio establishing line 26. The kickdown signal will persist, even if the accelerator is released, until a signal from either of two inputs 29, 30 is impressed on a memory device Q, resulting in removal of the signal in line 22 and appearance of a signal in a line 21. Input 29 is energized in response to an upshift, and input 30 in response to vehicle acceleration exceeding a predetermined amount. A code corresponding to the highest permissible ratio is then transmitted from the circuit 5 through an AND gate 14 to the line 26.

Title: Improvements in grain cleaning machines
IPC: B02B3/10
Filed: 1930-04-22
Abstract: 353,915. Scouring and polishing grain. UNSTEAD, A. E., Charlton, Victoria, Australia. April 22, 1930, No. 12455. [Class 58.] In a grain-cleaning machine, grain is first submitted to a scouring action by movement between an abrasive-surfaced roller and a concave brush from which it falls in a thin stream on to a polishing device comprising relatively moving brushes, being subjected, during its fall, to aspiration. Grain is fed by a shoot 4, having a central and two side legs, into a hopper 3 at the bottom of which is a feed roller 9, fluted axially or helically and working in a curved extension 12 of the hopper, by means of which the grain is fed in the form of a thin curtain to a scouring device, the rate of feed being controlled by a yielding hinged regulator plate 13. The scouring device comprises a horizontal roller 16 rotated in a concave brush 21, the roller being solid and of wood, or comprising a number of spiders with wooden stocks attached thereto and mounted on the shaft 18, the outer periphery being of emery cloth or having a coat of emery cement or being faced with wire netting. The brush 21 comprises longitudinal stocks 22 with. inwardly and radially projecting bristles, the stocks being secured to curved angle-bars 24 tied together by rods 28 the ends of which pass through parallel slots in the machine casing and are screw-threaded to receive locking nuts. The individual stocks may be adjusted by packing-strips. Guard plates 32 protect the ends of the brush, a plate 33 preventing grain from passing behind the brush. The grain then passes down a perforated metal shoot, aspiration taking place therein due to a fan 41 and being controlled by a damper 40, dust being removed by the pipe 44 and heavier impurities falling into a settling-chamber 46 having a screw conveyer. A hood 48 prevents aspiration of the grain in its fall from the feed roller. The polishing device comprises a rotary brush 49 and a stationary concave brush 54 of the same form as the brush 21. The grain thence passes to a discharge trough 58 by way of an inclined plate 56 forming the base of a delivery compartment 57, the rate of discharge from which is controlled by a pivoted flap 59 having a counterweighted lever attachment. Final aspiration is effected by passing air through a gap at the top of the discharge trough 58 into a passage 64 communicating with the settling chamber 46, one side of the passage 64 being formed by a partition 66 with an adjustable portion 66a. Doors and windows are provided in the casing, and the movable parts are driven by belt and pulley drives.
