Title: Silicon nitride material for bearings
Inventor: LUCEK JOHN WILLIAM
IPC: F16C33/30
Filed: 1986-06-13
Abstract: The reliability of silicon nitride bodies for use in bearings can be greatly improved by control of microstructural flaws which produce bright specular reflections when metallographically prepared surfaces of the composites are examined microscopically in low angle incident light, dark field reflected light, or reflected polarized light viewed through a crossed polarizing analyzer. The population of such flaws can be controlled by modestly increasing the normal amount of intergranular phase and longer than normal milling times before sintering. Size classification of the powder before compression also improves the performance of the body. The fatigue cycles to failure of ten percent of the silicon nitride surfaces tested at 6.9 GPa contact stress in accelerated bearing failure ASTM Test STP 771 (L10 parameter) for sintered bodies prepared according to this invention is increased by about an order of magnitude over the values obtained with the best previously known type of silicon nitride body for bearing applications.

Title: Flushing arrangement for syrup line of post-mix beverage dispenser
Inventor: MCMILLIN JOHN R
IPC: B67D1/07
Filed: 1986-08-26
Abstract: A post-mix beverage dispensing system has a structure for flushing the dispensing valve and its nozzle of syrup using diluent water from the water supply. The dispensing valve 12 has a nozzle 34, syrup 46 and water 40 valves openable by an actuator; a mounting block 22 for the dispensing valve has water and syrup ports with disconnect valves 36, 42 in the outlet enabling removal of the dispensing valve 12 from the block 22; a flush connector and push-button actuated valve across the bottom of the block is fluidly connected into the water 18 and syrup 20 lines. Syrup is dispensed from pressurised source 16 via non-return valve 66, or from bag-in-box 16B by pump 68; either prevents flow of water from carbonator 14 into the syrup supply. The syrup line is flushed by connecting the water line 18 to the syrup line 20 via the valve shown; this may have structure for neutralizing the syrup pressure so that it cannot open itself if water pressure drops, and a lever type flush actuator behind the dispensing actuator lever enables easy flushing by squeezing the two levers together. <IMAGE>

Title: Recovery of titanium dioxide from ilmenite-type ores
Inventor: MANI KRISHNAMURTHY NAGASUBRAMA
IPC: C01G23/053
Filed: 1986-12-01
Abstract: A process for recovering titanium dioxide, useful as a white pigment, from ilmenite-type ores comprises digesting the ore with hydrofluoric acid to produce a fluoride salt-containing solution, treating the fluoride salt-containing solution with an alkali metal salt (preferably KCl) to precipitate alkali metal fluotitanate, treating the precipitate with a base to produce hydrated titanium dioxide and alkali metal fluoride, subjecting the alkali metal fluoride to electrodialytic water splitting to produce base and hydrofluoric acid, employing a portion of the base in the precipitate treating step and recycling a portion of the hydrofluoric acid to the digesting step. The hydrated titanium dioxide can be calcined to produce titanium dioxide.

Title: Barbell
Inventor: LEE SUK YOUNG
IPC: A63B21/072
Filed: 1987-01-12
Abstract: A barbell comprises a bar 1 and a weight 2 mounted on the bar by the bar passing through a central hole in the weight. Hand-grip regions 3 of the bar are adapted to be gripped by the user during exercise, the hand-grip regions being positioned one on each side of the weight. The weight is elongate along the length of the bar and roughly square-shaped in cross-section, to allow the bar to pass close to the chest of the user during use. The centre of gravity of the weight may be displaced from the axis of the bar sufficiently for the weight to rotate relative to the bar during lifting by the user so as to avoid the twisting force of the weight due to its moment of inertia being transferred to the wrists of the user. <IMAGE>

Title: Contact lens cast moulding and packaging
Inventor: HAMILTON RONALD SHADE
IPC: G02C7/04
Filed: 1989-10-27
Abstract: Contact lens is cast by polymerising a monomer in a cavity between a male mould and a female mould. When the moulds are opened, the lens remains supported on the surface. Cover is sealed onto the flange to form a package. Lens is cast with the male mould (12) facing downwards and female mould, which has an annular wall and flange similar to the wall and flange (22), is fitted piston-like with the male mould. Cavity is sealed properly and that the moulds retract to take up shrinkage when the lens is polymerised in a pressure vessel at, e.g. 0.2-1 bar. Surface is flame polished to ensure that the lens remains attached to the male mould when the moulds separate. Male mould is then inverted to face upwards and form an open container. Saline fluid is poured into the container to hydrate and ease the lens from the mould. Finally a removable lid is applied to the flange.
