Abstract: Abstract of the Disclosure A method is provided for the powder metallurgical manufacture of precision components from sintered steel using phosphorus without the usual drawback of shrinkage of the green compacts during sintering.  An iron based powder mixture containing, in addition to iron, 0.65 to 1.1 weight-% phosphorus, up to 0.6 weight-% carbon or graphite powder, and a lubricant is compressed into green compacts and sintered at a temperature in the range 950 - 1250°C for 5 to 90 minutes in a reducing atmosphere having such a carbon potential that the sintered compacts have a carbon content of between 0.05 and 0.6 weight-%.  The dimensional change during sintering is negligible and the steel resulting has both high strength and ductility.

Abstract: ABSTRACT OF THE DISCLOSURE         A roller skate incorporating a bi-wheeled design.  A base member is incorporated for supporting the user's shoe or foot.  A pair of parallel flanges depend downwardly from forward and rearward sections of the base member, each pair of parallel flanges having journeled therebetween a wheel assembly.  Each wheel assembly is comprised of a cylindrical core which is jour-neled about an axle affixed intermediate the flanges.  The rolling surface is fabricated from a thermosetting plastic and is uniformly disposed about the center core.  The lateral edges of the rolling surface overhang the core to permit the user to utilize the skate at the smallest possible angle with respect to the floor while simultaneously avoiding contact between the floor and the skate flanges.  The radius of curvature of the peripheral surface of the wheel is long enough to provide a substantially flat surface along the outer edges thereof to maximize the traction between the skate wheels and the floor while permitting same to be utilized at high speeds.

Abstract: ABSTRACT            A  range of alkali   metal borosilicate glass compositions modified by the addition of alkaline earth metal oxides has been found to be especially suitable for the production of graded index optical fibre by thermal diffusion using the double crucible method.  A core glass chosen from this range may be paired with a suitable cladding glass so that, in the nozzle of the double crucible, alkaline earth metal iron exchange occurs to give a composition gradient of alkaline earth metal oxide and hence a gradation of refractive index. Using these glasses, fibres have been produced having refractive index profiles that approximate closely to the ideal parabolic distribution, numerical apertures of up to 0.21, and best loss values as low as 6.4dB/km at 850nm.

Abstract: ABSTRACT OF THE DISCLOSURE      A hydraulic motor drives the cooling fan of an internal combustion engine.  Fluid flow from a fixed displacement pump is directed through a pilot-operated pressure-compensated control valve to the hydraulic motor.  The valve has a continuous bias to a fan-on position for directing fluid to the fan motor.  Flow to the fan motor is diverted by the valve as a function of the pressure of the fluid in the system.  In addition, flow to the fan motor is diverted as a function of a pilot pressure signal which is controlled by the temperature of the engine coolant fluid.  The valve failsafes to a condition directing maximum flow to the fan motor in the event of loss of pilot fluid pressure.
