Abstract: 1319268 Anti-skid systems TOYOTA JIDOSHA KOGYO KK and NIPPONDENSO KK 8 Oct 1970 [16 Oct 1969 (2)] 47972/70 Heading F2F In an hydraulic vehicle braking system a signal from a control circuit 60 indicative of a skid condition causes a piston 72 of a three-way electromagnetic valve 70 to move to the left thereby disconnecting passages 76 and 77 of which passage 76 is permanently connected to engine intake 80 and connecting passages 77 and 75 of which passage 75 is permanently connected to atmosphere. Atmospheric pressure is thereby introduced into a compartment 94 of a brake torque regulating means 90 to cause a piston 95 to move upwards to close a valve 96a, 96b, thereby cutting off communication between a master cylinder 30 and a wheel cylinder 20 and allowing the volume of a compartment 97a to expand; the pressure in wheel cylinder 20 is thereby reduced to reduce the braking torque. The signal is generated by a differential amplifier 108 upon an actual wheel speed voltage given by a D.C. generator 50 becoming higher than a reference speed voltage given by a generator comprising capacitor 101, diode 102, transistor 103, and resistor 104, 105. The reference wheel speed voltage may take a number of different values including an initial voltage lower than the actual wheel speed voltage, a first reference deceleration voltage and a second reference deceleration voltage, and said reference wheel speed voltage is switched from said initial voltage to said first reference deceleration voltage at the instant when the rate of decrease of said actual wheel speed exceeds a predetermined value. In the circuit illustrated in Fig. 3 an acceleration detecting circuit 110-115, 117, 132 is connected in circuit with generator 50 and differential amplifier 108 for generating a signal when the actual wheel speed voltage continues to increase during a predetermined interval after the termination of the braking torque reduction signal; also included are a reduction signal detecting circuit 128-131, a logic circuit 127 118, a reset circuit 123-125 and a circuit 119, 120, 122, 126 which generates an output signal which maintains the first reference deceleration voltage when the brake torque reduction signal from amplifier 108 has been terminated and also acts to switch the first to the second reference deceleration voltage according to the actual wheel speed voltage after the termination of the brake torque reduction signal. The circuitry of Fig. 5 includes a register circuit 201-207, 211, 213, 214 and a further differential amplifier circuit 116, 118, 200, 208- 210, 212, 215.

The swinging arms 21 of the brush 9 are carried on a frame 22 suspended by rollers 23 from a rail 24 and driven therealong by an electric motor (not shown). The frame 1 is mounted on rollers 31 running on rails fixed in the floor and is driven therealong by an electric motor (not shown). Water, or water and detergent, is supplied via piping 28 to the nozzles 29, or detergent may be applied by separate nozzles (not shown). Initially the car to be cleaned is arranged with its front edge level with the front walls 27 of the frame 1, the brush 10 is swung clear into its dot-dash position, and the brush 9 is rotated and driven along the rail 24 and back to clean the front of the car. Next all three brushes 8, 9, 10 are rotated and engage the car and the frame 1 is driven along the rails fixed in floor in the direction of the arrow 32 to clean the sides of the car. Next as one of the brushes 9, 10 loses contact with the car and swings in the direction of the arrow 32, the motor driving the frame is switched off, and the brush 9 cleans the rear of the car as it cleaned the front. Next, the motor of the frame 1 is driven in reverse while the brushes 9, 10 are held away from the car sides by the arrangements 25, and the brush 8 is lifted from the car by the arrangement 17 to move the frame back to its initial position where all the drives are switched off. Alternatively, a cleaning process may be performed during the return of the frame, the brush rotation being reversed. The above operation may be fully automatic or hand control of the single processes may be used.

Title: Process for the preparation of finely porous moulded parts by setting of polyester-containing moulding compositions
IPC: C08L67/06
Filed: 1965-11-16
Abstract: Finely porous moulded parts are made by the setting of a polyester-containing moulding composition which contains a chemically unsaturated polymerizable compound and water in the form of a water-in-oil emulsion from which, after setting, the water is removed and characterized in that a cross-linkable elastomer or compound capable of forming an elastomer is added to the unsaturated polymerizable compound in the period of time before setting, and is cross-linked simultaneously with or, preferably, after the polymerization of the unsaturated compound. Butadiene acrylic acid/ester copolymer may be used as the polyester base, together with acrylonitrile, and its copolymer with butadiene; ethyl acrylate, methyl acrylate, vinylidene chloride, styrene, vinyl acetate, and copolymers thereof.  The acrylates may also be used as polyester bases.  In examples the composition comprises ethylacrylate and styrene; butadiene and acrylonitrile, and ethylacrylate and chlorethyl vinyl ether.  The polymerization may be conducted in the presence of a catalyst in the range 50-80 DEG  C., followed by cross-linking at over 100 DEG  C. using a peroxide as catalyst.  This latter treatment usually is effected in an atmosphere of water, e.g. steam, to prevent premature foaming. This treatment may also be conducted in a liquid salt bath or in a bath of, e.g. an alcohol of boiling point above 100 DEG  C.  After this the composition is dried to remove water.ALSO:Fabrics, e.g. cotton, wool, rayon or polyamides, which may be needled, are coated with a polyester-containing composition which contains a chemically unsaturated polymerisable compound and water in the form of an oil-in-water emulsion, and also contains cross-linkable elastomer or compound capable of forming a cross-linkable elastomer which is added before setting of the composition and which is cross-linked simultaneously with or preferably, after polymerisation of the unsaturated polymerisable compound, the water in the composition being expelled after setting thereof to produce a finely porous coating.

Filed: 1969-10-08
Abstract: 1,240,072. Drying gases. MALONEYCRAWFORD TANK CORP. 8 Oct., 1969 [24 Oct., 1968], No. 49410/69. Heading B1L. Water vapour is removed from natural gas at the wellhead by passing the gas upward, in overall countercurrent flow to a preferably refrigerated calcium chloride brine having an initial specific gravity of 1.35-1.40, through a series of scrubbing tray systems, the flow of brine and gas within each tray system being cocurrent. As shown, one such tray system comprises tray 42 extending across column 10 and superposed above tray 40 which does not entirely extend across the column. As brine passes down the column it is caught by tray 42 and passed by central downcarrier 44 to tray 40 where it collects until it reaches the level of weir 64 (see also Fig. 2, not shown), when it passes into space (50) and drains therefrom to the next lower tray system. Rising gas passes up through nozzles 46, 48 and (50) and entrains brine in its passage through concentric housing 47. Deflector 70 knocks down the entrained brine which collects in tray 42 and passes thence back to tray 40, while the gas stream passes on up the column. An alternative form of tray system is illustrated in self-explanatory Fig. 4 (not shown). The dilute brine effluent is not reconcentrated for reuse, and the apparatus is well-adapted for use at off-shore wellheads.
