Abstract: 1,124,117. Ventilating floors for silos &c. E. W. BORROW. 30 Aug., 1966 [2 Sept., 1965], No. 37460/65. Heading A2Q. [Also in Division F4] A ventilated floor, for supporting loose material such as grain being dried, chilled or conditioned by air, comprises a step or a plurality of parallel steps with a perforated riser for each step, through which riser air can pass or be passed into and through the loose material. The floor, Fig. 1 may comprise two or more sheets, e.g. of galvanized steel, having bent and perforated edges or flanges 8 pierced by holes 9. The sheets may be secured together by bolts, so that adjacent flanges 8 overlap, with their perforations 9 in register, to form a perforated riser. Each step may slope downwardly. In an alternative construction, Fig. 4, the floor may comprise an inverted trough 14, whose sides are formed with one or more perforated risers 15 and downwardly sloping steps. One or more horizontal partitions 16 with perforated edges may be supported, along said edges, by risers at each side of the trough, to divide the latter into two or more chambers; the perforations in the edges being in register with those in the risers. The trough may be connected to a souce of compressed air, and a movable flap may be provided at the entrance to each chamber to control the in-flow of compressed air. In a further construction, Fig. 2, the floor 12 of a grain silo 11 comprises a plurality of sector-shaped, stepped ventilating panels 12a, 12b having perforated risers, which panels are inclinedly arranged to provide radial troughs with radial ridges between them. A horizontal motor-driven auger 13 is provided in each trough. Grain fed on to the floor 12 flows downwardly, over the sloping panels, into the troughs, from which the grain is conveyed, by the rotating augers 13, to a central collecting point. Compressed air fed under the floor flows through the perforated risers and the grain, and may assist the downward flow of the latter.

[Class 28 (ii).] In an appliance for holding and facilitating the slicing of meat &c. the pusher plate h is moved towards the open end of the container a by a lever f which is shaped to enable it to be pivoted at the side of the container and is actuated from a position also at the side of the container. The container a is mounted within a base b integral with a housing c which contains the screw operating mechanism. The plate h has bosses h<1> through which spikes g protrude, the meat being impaled on the spikes. The plate is steadied by lazytongs i, i<1>, i<2>, i<3> pivoted at one end to a fitting b<1> on the base and at the other end to a fitting b2 on the plate. The lever f which may consist of two spaced members, bears on rollers carried at the back of the plate h. The container a seats against a rubber packing ring b<8> and is held by a strap b<4> which is secured by clips tightened by screws b<5> on the housing c. The knife is steadied by a ring j which is slightly spaced from the front of the container and is secured to a strap j<5> which is clamped around the container over an elastic ring j<2> by a bolt j<5>. The extension of j<7> of the ring j is secured in a recess in the strap, and the screw holes are elongated to permit adjustment of the ring j.

Title: Device for use on vehicles equipped with hydraulic brakes for varying the braking force on vehicle wheels dependently upon the wheel load
IPC: B60T8/26
Filed: 1963-09-30
Abstract: 1,012,775. Fluid-pressure brakes. FIAT S.p.A. Sept. 30, 1963 [Oct. 26, 1962], No. 38436/63, Heading F2F. In apparatus for varying brake pressure in an hydraulic braking system of a vehicle which includes a pressure varying device of the kind comprising a differential piston acted on by pressure in a master cylinder against spring means to close a normally open valve when master cylinder rises above a predetermined value, whereafter the piston is effective to vary the pressure to certain wheel cylinders of the vehicle, the predetermined value is varied through a connection between the piston and an unsprung part of the vehicle which includes a spring member. In one embodiment, Figs. 2 and 4, the device VP is mounted on the vehicle body adjacent the rear axle casing 19 and comprises a differential piston 2 presenting a larger face to a chamber 7 and a smaller, annular, face to a chamber 5, the chambers 5 and 7 normally being interconnected by a valve formed by an annular member 17 formed to provide by-pass passages 15, 16. Piston-rod 3 extends through a seal 10 to the exterior of the device where it is connected to a lever 21, pivoted at 20, by a pin 25 and slot 24 in the lever. A spring 9 biases the piston to maintain passages 15, 16 open, assisted by an optional spring 26. Lever 21 is connected to a strap 23 on the axle casing 19 by a tension spring 22 opposing and modifying the action of springs 9, 26 according to vehicle load. In operation, as master cylinder pressure rises fluid enters through port 8 to chambers 5 and 7 until the pressure overcomes the resultant effect of the springs 9, 22, 26, causing piston 2 to move down and close off passages 15, 16, whereupon the piston operates to reduce pressure in accordance with the ratio of the areas of its faces. Piston seal 13 operates as a one-way valve permitting return of fluid via a passage or passages 14. In a second embodiment, Fig. 7, the pressure varying device is as in the first embodiment except that the seal 13 is of different cross-section, and the spring 9 is stronger so that spring 26 is omitted. The tension spring between the lever 21 and the axle casing is replaced by a rod 28 acting via a compression spring 22 so as to urge the lever 21 in the same direction as previously. In another embodiment, Fig. 10, a torsion bar 36 to which are secured long and short arms 37, 35 respectively engaging the axle casing and the piston rod replaces the spring 22. In a further embodiment, Fig. 12, the spring 9 is omitted, a single compression spring 43 acting directly between the piston rod 3 and the axle casing 19, with or without the interposition of a known levelling device comprising a piston 47 and cylinder 48 to which fluid is supplied as desired.

Abstract: 1,097,956. Transistor logic circuits. ENGLISH ELECTRIC COMPUTERS Ltd. Dec. 15, 1966 [Sept. 16, 1965], No. 39314/65. Heading H3T. A logic circuit comprises two transistors 20, 21 having their inputs connected to respective diode logic circuits 16, 19, their collectors and emitters being connected to respective common resistors R 2  and R 3 , an output connection to R 3  and anti-saturation resistors R 1  between their collectors and bases. The circuits are described as operating with signals having levels of D and 3D, where D is the forward voltage drop across a diode and across an emitter-lane junction. When all inputs 10-15 are D, the bases of 20 and 21 are 2D, the base of 27D and thus the base of 28 is too low for conduction. Accordingly, 28 is cut off and output terminal 30 is at the voltage 3D, the supply potential of line 29. When all the inputs to the gate 16 or 19 are 3D, the base of 20 or 21 rises (in fact to 3D), 27 to 2D and 28 to D so that terminal 30 falls to D. Transistor 28 is prevented from saturating by connecting it to the second emitter of transistor 27 and transistors 20 and 21 are prevented from saturating by connecting resistors R1 to the output of transistor 27. The logic circuits 16, 19 and 23 are and AND or OR depending upon the polarity of the logic. The additional supply for 29 may be omitted (Figs. 2 and 3, not shown) if a clamping diode (35) is provided for the collector of transistor 28, the diode being connected at its other end to a supply of valve 2D or to the base of transistor 27. Alternatively, an emitter follower (37) could replace the diode, the emitter being connected to the base of 27 and the collector to the supply 25 or the lower end of resistor R2 (Figs. 4 and 5, not shown). In each of the embodiments R 6  could be connected at its upper end to the lower end of R 2  (Figs. 6, 7 and 8, not shown), R 6  being designated R 7 .
