Abstract: 1,227,950. Anti-skid braking systems. MULLARD Ltd. 7 June, 1968 [31 Oct., 1967], No. 49462/67. Heading F2F. In an anti-lock brake system, a valve Vs, connected between the master cylinder and the wheel brake, is actuated in response to a signal from a wheel speed sensor to allow fluid to flow from the brake, the flow of fluid from the master cylinder to the brake then being prevented or reduced by a valve V1. As shown, when valve V8 is actuated to move it to the right, fluid is allowed to flow via path B to a reservoir (R) and chamber C1, the fluid pressure in chamber C1 thus causing valve V1 to close and, when this pressure exceeds a preset limit, valve V2 to open. Fluid pressure in chamber C2 then moves a piston p into engagement with a cam rotated with the wheel thus causing the piston to act as a pump for pumping fluid via valve V3 and chamber C3 either to the brake, if the valve V8 has already been released to the position shown, or to the master cylinder either directly via path L or indirectly via valve V4. In modifications, the valve V8 may be modified to open and close path B only, Fig. 2A (not shown), the connection between the master cylinder and the brake then only being closed by the element V1c of valve V1. Further, element V1c may be provided with a leakage path between the master cylinder and the brake so that the flow of fluid to the brake is varied in dependence on the volume or pressure of fluid in the reservoir. Alternatively, a leakage path may be provided in valve V4. If it is required to pump fluid back to both the master cylinder and the brake simultaneously, an additional reservoir R(a), Fig. 3 (not shown), may be provided which is connected via a restriction to the valve Vs and is provided with a pump (pa) which is arranged to return the fluid to the master cylinder only. The rest of the system is substantially as shown in Fig. 2. Alternatively, a single reservoir may be provided in conjunction with two pumps. This type of system automatically adapts it to changes in the quality of the road surface. The above antiskid system may be provided for each wheel or may be provided for each front wheel and one for both back wheels, each system being provided with its own wheel speed sensor, and with individual or common reservoirs.

A stabilised substantially anhydrous uniform composition which may be used as a bleaching and reducing agent comprises a metallic dithionite and a cationic, non-ionic or amphoteric surfactant. The preferred dithionite, which may be used as the hydrosulphite, is that of sodium. The surfactant may be formed from ethylene oxide and an aliphatic alcohol, e.g. cetyl and/or stearyl alcohol with a molar ratio of 15-25:1 of oxide: alcohol. Examples are given of suitable surfactants, all of which may be used in compositions containing 0.5 to 40% by weight of surfactant by weight of dithionite. Freeflowing agents, e.g. urea may also be added to the composition in concentration of from 60 to 100% by weight based on the weight of surfactant. The composition may be prepared by adding the dithionite to a melt of the surfactant and cooling to form a solid followed by crushing in a disintegrating mill to form a crushed intimate mixture.

Abstract: 1,265,881. Cathode materials and processing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 April, 1969 [4 April, 1968], No. 16969/69. Heading H1D. A thermionic electrode comprises a metal sheet support having on one surface an electronemissive coating and on the other surface a coating of a getter material which diffuses through the support and has an activating influence on the electron-emissive coating. The sheet metal support may be of Mo, Ni-plated Fe, Ni or "cathode-Ni" (i.e. Ni with a small amount of Mg, Al, Si or Zr) and between 20 and 100 Ám thick. The getter material, which is of the high temperature type since it is heated together with the emissive material, may be Zr, Ti, La, Ce or Th and may contain 20-60% by weight of W and/or Ni powder. In coating the support with getter material, metal particles, e.g. of V, Mo, Fe, Co or, preferably, Ni, are first sintered on to the support surface and the getter material, generally in the form of hydrides, is provided in the interstices between the metal particles and the coating thus formed compressed between rollers to trap the getter. The coating of emissive material on the other face of the support may be provided in a similar manner, and may comprise Ba, Ca and Sr carbonates with 1-10% by weight of Ti, Zr, Hf or Th, having a density of between 1 mg. and 10 mg. per square centimetre of emitting surface. The electrode is activated by heating. In an example the support strip is "cathode-Ni" containing 0À03-0À09% by weight of Mg, is 50 Ám thick and the coatings on each surface are 10 Ám thick, the getter being Zr with 30% by weight of Ni. The getter material is also an activator for the emissive coating, e.g., the getter may include Zr which diffuses through the support to reduce, for instance, BaO to free Ba. The electrode may be used in a diode or triode, Figs. 1 and 5 (not shown) and may comprise a cylindrical support with the emissive layer on the outside and the getter layer on the inside surface and housing a heater. Alternatively, in a low pressure Hg vapour lamp for example, Figs. 2 and 7 (not shown), the emissive layer is on the inside and the getter on the outside of a cylindrical support. Furthermore the electrode may be used in an electron gun of cathode ray tube. Electrode dimensions are given in a number of examples. In manufacturing a support, Ni particles may be magnetically aligned prior to sintering.

[Also in Divisions C1 and H1] Nickel, cobalt and iron phthalates are made by dissolving a nickel, cobalt or iron salt in a dialkyl sulphoxide (e.g. dimethyl sulphoxide) adding phthalate ion to the solution, precipitating metal phthalate by adding water, separating and drying the precipitate. Mixtures of phthalates can be obtained by using more than one metal salt, and a fine precipitate can be produced by subjecting the water-diluted dialkyl sulphoxide solution to ultrasonic vibration. The phthalate ions may be derived from phthalic acid, phthalic anhydride or Na, K and NH 4  phthalates.

Abstract: 1297053 Valves FRANCE ARMED FORCES MINISTER OF 3 March 1970 [4 March 1969] 10216/70 Heading F2V Flow from a high pressure inlet Ca to one or more outlets Cd, is controlled by a piston P1 whose movement is governed by a toggle linkage B1, B2, B3 having a damping piston P2 connected thereto. In the state of the valve shown, the linkage is restrained from collapsing by a retaining pin V1 subject to the control of a pneumatic jack. With the pin V1 released, the linkage collapses as a result of the inlet pressure acting on the piston P1 and/or as a result of a release pin P2 engaging toggle link B3, the release pin being under the control of a pneumatic jack. Movement of piston P1 consequent to the collapse of the toggle linkage, is damped by damping piston P2 which compresses the air contained in a valve damping chamber A1. The transfer of shock from piston P2 to piston P1 is prevented by the provision, within the damping piston P2, of a throttling orifice M1 through which oil contained in chamber A2 is made to pass. Upon the pressure within the inlet Ca being reduced, the valve is returned to the position shown by the compressed air in chamber A1 acting on the damping piston P2. In the state of the linkage shown, the retaining force acting on link B3 is smaller than the force acting on piston P1.
