Abstract: ABSTRACT         A process is provided for removing impurities from a slurry of titanyl hydrate.  The titanyl hydrate is separated from the slurry, washed, and reslurried with water to make the resulting titanyl hydrate slurry fluid. The reslurried titanyl hydrate slurry is then treated by the addition of a trivalent titanium compound in an amount between about 0.01 grams and about 0.7 grams trivalent titanium compound measured as TiO2 per 100 grams titanyl hydrate as calcined TiO2 in the absence of additional acid values.  The titanyl hydrate is then separated from the treated slurry, washed and recovered.

Abstract: ABSTRACT OF THE DISCLOSURE           A protective cab for the operator of a walk-behind tractor such as a snowthrower is enclosed on its front and lateral sides by large window panels of transparent plastic material extending between a top and a bottom shroud.  A pair of frames inter-connect the top, the panels and the shroud and together with a pair of braces, connect the cab to the handlebars and handlebar support.  A transverse trough minimizes flow of water over the rear edge of the roof thus enhancing the comfort of the operator.  The shroud protects the operator against upwardly swirling winds and provides pocket means useful for temporarily storing personal items.

Title: Method for brightening surfaces and composition  therefor
Inventor: ROBSON TERRANCE P
IPC: C11D3/395
Filed: 1982-08-19
Granted: 1985-11-26
Abstract: Abstract The disclosed method for brightening the stains on a stained surface involves the spraying of a combined multi-part system typically made up from three separately prepackaged parts:  (a) a nonionic surfactant of the ethoxy-late type (e.g. a surfactant of the formula  , wherein R is a hydrophobic organic radical and n ranges from 3 to 40), typically diluted with water, (b) a solid, particu-late mass of water soluble persulfate salt, and (c) a concentrated aqueous solution of H2O2.  A proper balance between the relative amounts of the three parts provides an adequate pot life before spraying, good brightening and cleaning, and a modest, sustained rate of decomposition of the H2O2.

Abstract: PROTECTIVE CONTROL ARRANGEMENT FOR DUTY CYCLE CONTROLLED          SHEATHED HEATING ELEMENTS ABSTRACT OF THE DISCLOSURE     A protective control arrangement for an apparatus incorporating one or more heating units of the type comprising the concentric assembly of a resistive heating element embedded in an insulating material enclosed within a metallic sheath energized in accordance with a duty cycle power control scheme, which prevents the rupture or separation in the sheath caused by an arc at a discontinuity in the heating element from propagating along a substantial portion of the sheath. In one embodiment, a microprocessor control led relay associated with each heating element selectively couples and decouples its associated heating element and the power supply.  The microprocessor is preprogrammed to control the duty cycle of each heating element by periodically opening the associated relay switch, thereby decoupling the heating element from the power supply for idle periods of predetermined duration.  A timer monitors the time between power decouplings.  Whenever the time between power decouplings for any heating element exceeds a predetermined maximum time, the microprocessor decouples power from the heating element for a predetermined recovery period.  The maximum time is selected so as to confine the propagation time within a predetermined limit.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an optical system which will enable easy use in the field.  Known systems either require sample and reference targets to be imaged within the telescope field or do not enable accurate identification of the measuring field in a view finder.          The present invention overcomes this problem by providing a system having a first branch and a second branch which receive light from a sample and reference target respectively.  A shutter sequentially allows light from the two branches to pass to a mirror having a slit, reflective portions and transparent portions.  Light from the first branch passes through these portions to a detecting branch and some light is reflected through a lens to an eye piece.  Similarly some light from the second branch passes through the mirror to the eye piece and some light is reflected to the detecting branch.  Accordingly the measuring field can be accurately identified by looking through the eye piece whilst at the same time light is directed to the detecting branch for analysis.
