Abstract: 1,259,450. Hydraulic braking systems. AISIN SEIKI K.K. 13 July, 1970 [14 July, 1969], No. 33862/70. Heading F2F. In a load responsive braking force regulating assembly for a motor vehicle an hydraulic pressure control device 14 is provided having a spring biased piston 31 which interrupts the flow of hydraulic fluid from an inlet port 41 to an outlet port 42 at a specific cut-out pressure the spring 19 biasing the piston 31 so that, a downward force on the vehicle chassis up to a predetermined value increases, and above that value decreases, the cut-out pressure. In normal braking hydraulic fluid passes from a master cylinder to a brake mechanism by way of ports 41, passages 38, 45; 36, a chamber 39 and port 42 until the hydraulic pressure reaches the predetermined value at which point the communication is broken by the piston 31 moving leftwardly so that a piston shoulder 46 engages a valve cup 35. A further increase in pressure moves the piston rightwardly to re-establish communication and the cycle is repeated. A ball 43 engages a pin 48 of piston 31 and also a base-plate 44 welded to a lever 18 pivoted at 17 to a flange 16 and mounting the compression spring 19 attached to a vehicle axle 47. Below a predetermined loading the spring 19 biases the piston rightwardly to increase the cut-out pressure, but above that loading the cut-out pressure decreases. The spring 19 may be replaced by a leaf spring (51), Fig. 4 (not shown), and the lever by a connecting rod (50) or the spring may be pivoted to the flange 16. In a further construction lever 18 is pivotally mounted to flange 16 and a coil tension spring (119) is pivoted to the flange 16 and to the axle.

Abstract: 1301380 Electromagnetic rotary indicators; automatic fault indication SPERRY RAND CORP 15 Dec 1970 [19 Dec 1969] 59463/70 Headings H2A and H2K The correct operation of an electromagnetic indicator comprising a permanent magnet 12 and a plurality of windings 111-120 is checked by detecting the voltage induced in one winding when another winding is energized, the magnet carrying a body 15 of magnetically permeable material to provide magnetic coupling between the two windings. The body 15 is an arcuate, metallic strip attached at one end to one pole of the magnet, its length preferably being about 20% greater than the angular spacing of adjacent windings, where for any desired rotor position the winding whose induced voltage is detected is adjacent the energized winding. The magnet also carries a balancing weight 16. When the rotor reaches its desired position, the induced voltage, which is fed at point c, Fig. 3b, to a level detector S12, turns on a transistor Q 3 . As a result, diode CR1 is forward biased and capacitor C 2  discharges. A transistor Q 5  remains in the ON condition and a spring loaded fault indicator 210 remains out of view. In the event of faulty rotor position or an electrical fault in the winding connected to the level switch S12, transistor Q 3  is not turned on, CR1 is reverse biased and capacitor C 2  charges up through resistor R 6 . After a time delay, sufficiently large to allow the magnet to reach any position, unijunction transistor Q 4  is triggered and turns off transistor Q 5 , allowing the fault indicator 210 to come into view.

Preferably the grinding is carried out so that the solid remains entirely below the surface of the liquid during grinding, and the grinding may be performed in the substantial absence of air, the grinding chamber being substantially full of the organic liquid. The organic liquid used distils below 500‹C and has a viscosity below 600 centistokes at 100‹F. The surface tension of the liquid may be below 72 degrees cm at 25‹C. The weight of graphite and metal in the liquid mixture may be less than 50% by wt. The grinding may be continued until a surface area of 800 m<SP>2</SP>/gm is obtained. The grinding may be performed in a vibratory ball mill. The solid contained may be separated from the liquid mix and compressed e.g. at a pressure of at least 2v10<SP>3</SP>psi to form a composite which may have a resistivity of less than 150 ohm cm x 10<SP>-3</SP>. The metal graphite mixture may contain 1-80% by wt of metal. The composite may be used as a catalyst as an electrode in electrochemistry and in batteries accumulators and fuel cells. The resistivity of the complex is lower in a direction parallel to the axis of compaction than in a direction perpendicular to it. The ratio between the two can be as high as 10:1. The composites may also be used as solid lubricant bearing materials and as solid lubricant when dispersed in lubricating oils.

Abstract: 1340196 Road vehicle lighting systems JOSEPH LUCAS (INDUSTRIES) Ltd 28 May 1971 [27 June 1970] 31285/70 Heading H2H [Also in Division G4] A lighting system for a road vehicle comprises a series circuit including the vehicle lighting switch 12, a relay coil 15 and a tail lamp filament 17, a series circuit including the vehicle stop lamp switch 28 and a stop lamp filament 33, and a normally closed contact 15a of the relay, which contact when closed completes a circuit from the terminals of a battery 11 through the lighting switch, the contact, a resistor 38, a diode 37 and the stop lamp filament so that the stop lamp filament is illuminated at reduced intensity if the tail lamp filament fails. When the switch 12 is closed, side lights 30 and the tail lamps 17, 21 are illuminated. Operation of the stop lamp switch 28 causes a relay coil 29 to be energized thereby closing contacts 29a, 29b and energizing relay coils 31, 34 to close contacts 31a, 34a. Warning lamps 24, 27 are therefore illuminated at full brightness. If a tail lamp filament, for example the filament 17, fails the relay coil 15 is de-energized thereby closing the contacts 15a to illuminate the stop lamp filament 33 at reduced brightness by current supplied via the resistor 38 and diode 37 and to illuminate the warning lamp 24 at reduced brightness due to the insertion of a resistor 23 in the circuit. The circuit may also be used to illuminate a flasher lamp filament at the front of the vehicle if a side lamp fails, the stop lamp switch 28 being replaced by a direction indicator switch. The relays may be replaced by bimetal strips.
