Title: Improvements in or relating to motor vehicles
IPC: G05G5/24
Filed: 1933-11-10
Abstract: 429,922. Foot-operated brakes. BARNES, F. J. T., 184, Breakfast Creek Road, Newstead, Brisbane, Australia. Nov. 10, 1933, No. 31404. [Class 103 (i)] [See also Groups XXXI and XXXVII] A motor vehicle is provided with a rack pivoted to the brake pedal and guided in a housing secured to the steering column, and hand - operated mechanism also carried by the steering column, for moving a pawl into or out of engagement with the rack, whereby the pedal may be locked in its operative position. The pawl may be further controlled by a keyactuated lock so that the vehicle cannot be used when the pedal is thus controlled. The clutch and brake pedals may be interconnected so that the clutch pedal also controls the brakes but is not affected by depression of the brake pedal. In the construction shown the brake and clutch pedals 3, 4 have racks 2, 21 pivoted thereto which are guided in housings 5, secured to the steering column 6. The racks are adapted to be engaged by pawls 10, 10<1> which slide in the housings 5 and are connected by spring couplings 16 to rods 14, 14<1> mounted on the steering column. The upper ends of these rods. are adjustably secured, within a casing 21, to coupling members 31, 31<1> which are pressed downwards by springs, (not shown), and are adapted to be raised by hand levers 34, 34<1> when in the position shown in Fig. 7. When either lever is turned through 90‹ about a pin P the corresponding pawl is pressed down by its spring into engagement with its rack. The coupling members 31, 31<1> are provided with flanges 32, 32<1> which overlap a flange 40 formed on a rotary member 38 controlled by a hand lever 44, this flange having two portions 42 cut away. Thus, as shown in Fig. 5, in position a of the lever 44 both flanges 32, 321 are free to move up and down, in position b flange 32 is free but 321 is locked in either the up or down position in which it happens to be, and in position c both flanges 32, 321 are prevented from movement and both pawls 10, 10<1> are locked either in or out of engagement with their respective racks. If the pawls are locked in engagement with the racks and the pedals have been depressed, the latter cannot be released until the pawls have been freed by movement of the levers 44, 34, 34<1>. The lever 44 can be locked in any of its three positions by means of a keycontrolled barrel 47 having a flat portion 48 so that when in the position shown in Fig. 7 an upstanding rim 39 on the member 38 can rotate freely under the flat part. The rim is formed with three recesses 41, each corresponding to one of the positions of the lever 44 which is locked when the barrel is rotated into one of the notches.

Abstract: 960,533. Valves. HYDRAULIC UNIT SPECIALTIES CO. Aug. 16, 1962 [April 12, 1962], No. 31451/62. Heading F2V. A relief valve arrangement for relieving abnormally high and low pressures in a system having high pressure supply and low pressure return lines 8, 9 respectively which are communicable with one another through an annular valve seat 13 or 40, comprises a body 16 or 41 providing a cylinder 18 which is open at its front and closed at its rear, a piston 29 slidable in the cylinder, and poppet valve mechanism carried by the piston and guided thereby for movement toward and from a normally closed forward operating position in which the poppet mechanism blocks communication between the supply and return lines 8, 9. This poppet mechanism comprises a hollow low pressure outer poppet valve 19 or 22 which is fast with the piston and projects from the front thereof and having a system port 24 opening through its front for communication with the line 8 and an annular portion surrounding this port for engagement with the seat 13 or 40, an annular rearwardly facing valve seat 27 on its front portion through which the system port 12 or 45 opens to the hollow interior of the poppet, a reservoir port 26 opening through the side of the outer poppet to communicate the system port 12 or 45 with the return line 9 when the valve seat on the outer poppet is in open position. A spring 35 urges the outer poppet toward closed position, and a forwardly facing shoulder 38 on the poppet surrounding a front portion thereof, provides a surface upon which fluid in the return line 9 can act to unseat the outer poppet when pressure at the port 12 drops to a predetermining low relief valve below the pressure at the reservoir port 9. The poppet mechanism further comprises an inner high pressure poppet 32 supported from the piston to control communication between the ports 12, 9, this inner poppet engaging the seat on the outer poppet in a forward operating position and presenting a forwardly facing surface upon which fluid at the port 12 can act to unseat the inner poppet when the pressure reaches an abnormally high valve. A spring 34 maintains the inner poppet in its forward position as long as pressure at the port 12 remains below a predetermined high relief value, and a duct 36 that extends axially through the piston and the inner poppet, has one end in communication with the port 12 and its other end opening into the closed rear portion of the cylinder, so that fluid at normally high system port pressure will be maintained in the cylinder to bias the outer poppet, the duct 36 also allowing fluid to be exhausted from the cylinder to allow the outer poppet to open. In a modification, the inner poppet slides on a tubular extension of the piston.

Title: Improvements in or relating to the purification of sewage and other waste liquor
IPC: C02F3/12
Filed: 1955-11-10
Abstract: 804,249. Treating sewage and other waste liquors. KESSENER, H. J. N. H. and WHITEHEAD & POOLE, Ltd. Jan. 17, 1957 [Nov. 10, 1955], No. 32125/55. Class 111. In a process of purifying sewage and/or other waste liquor (e.g., industrial effluent), wherein a mixture of the sewage and/or other waste liquor with activated sludge is aerated and subsequently allowed to undergo main settling, some of the sludge is allowed to settle from the aerated mixture before the main settling and is returned to another portion of the mixture which has received less aeration or no aeration. In Fig. 3, tank 10 is divided by a central wall 11 into an inlet part 12 and an outlet part 13, wall 11 being of reduced height at one end of the tank so that the two parts are in open communication with one another. Sewage enters tank 10 through a plurality of inlets 16 distributed along an inflow channel 15 and leaves via weir 18 and channel 19. Two rotary aerators, carried by shafts 23, are provided, one adjacent each side of the wall 11. The aerator in the inlet part 12 of the tank extends along the whole length of wall 11, but the aerator in outlet part 13 stops short of the weir 18. Shafts 23 are driven, for example, by an electric motor, and the aerators comprise a plurality of brushes, vanes, plates or combs. The aerators are partially submerged in the sewage, with preferably less than half their bulk disposed below the surface. Sewage leaving tank 10 proceeds to a main settling tank, and activated sludge from the main settling tank is introduced into inlet part 12 of tank 10. Activated sludge which settles on the floor of the outlet part 13 of tank 10 is drawn by the action of the aerator 20 into the trunk 26 through its open end 27, passes through aperture 25 in wall 11 into trough 28 and is projected into the inlet part 12 of the tank by aerator 20. In Fig. 5, the aerators 20, 21 extend the whole length of wall 11 and a baffle 30 projects above the surface of the liquid, thus providing a region 31 which is shielded from aerator 21 activated sludge can thus settle in the region 31 to be drawn through trunk 26. The apparatus may be modified to carry out also the process of recirculation described in Specification 688,650. Specification 445,352 also is referred to.

Title: Process for the treatment of solid carbonaceous material for the recovery of oils
IPC: C10G1/04
Filed: 1927-11-30
Abstract: 305,744. Humphrey, H. A., and Imperial Chemical Industries, Ltd. Nov. 30, 1927. Coking processes.-Solid ca.rbonaceous material is distilled in oil by causing the comminuted material to move through a body of oil so as to be subjected to progressively-increasing temperatures. Superheated steam, or hydrogen, or a hydrogen-containing gas, may be introduced at the hottest part of the oil so as to increase the yield of oil and agitate the charge. The temperature-range varies from 100‹ C. at the top of the tower to 400-420‹ C. at its base. The. material may be fed in at the top of a tower containing oil the temperature of which is highest at the bottom, and its descent through the tower may be retarded bv shelves or cones with serrated edges to break up the upwardly-moving gases. The uncombined hydrogen is separated from the vapours given off at the top of the tower and re-used in the process. The pressure in the tower may be increased to 100 atmospheres to increase the hydrogenation. Two towers may be joined at their bases to form a U the liquid in which is subjected to periodic oscillation either by a piston or by alternate accumulations of gases in each limb. External heating may be employed or the superheated steam or gases may be used to heat the liquid internally and a catalyst may be used to promote hydrogenation, and heat exchangers may be used to recover heat from the outgoing hot fluids.

Abstract: 923,032. Conveying articles through baths. LONDON RUBBER CO. Ltd. Sept. 20, 1961 [Sept. 20, 1960], No. 32257/60. Class 78 (1). In the manufacture of rubber articles by dipping, each row of formers is carried by a board 17, and a plurality of the boards is given a step-by-step movement along and between rails 11 by the action of pushers 21. Each pusher 21 is pivoted at 19 to a trolley 12 running in guides 11, the pusher 21 being counterbalanced by weight 22, and being influenced by arm 24 carrying roller 25. Roller 25 is adapted to be engaged by ramp 26 when the latter is advanced by cylinder 29. The trolleys are connected rigidly together by bars 13 and are operated reciprocably by cylinder 16 connected thereto at 14. As each trolley reciprocates, each cylinder 29 advances its ramp 26 to engage its roller 25 to cause the lowering of pusher 21 into engagement with a board 17. Thereby a batch of boards 17 is given a simultaneous advancing movement corresponding to the movement of the piston of cylinder 16. This length of movement may be increased by the provision of a linkage 31 between two trolleys 12 as shown on the left of Fig. 1 so that as the trolleys reciprocate the pivot 34 strikes cam 32 to extend the linkage and thus give the leftmost trolley 12 an additional movement. When it is required that a batch of boards 17 should remain stationary during the movement of the trolleys, cylinder 29 is not actuated so that its pusher does not engage its batch and reciprocates without effecting movement of the batch.
