Abstract: HAZED TOOTHPASTE         ABSTRACT A hazed toothpaste which can effect dental remineralization and re-duce caries formation.  The toothpaste contains a binary fluorine-providing system which provides about 750-1225 ppm fluoride from sodium monofluoro-phosphate and about 50-1000 ppm fluorine from sodium fluoride and a syn-thetic precipitated siliceous polishing agent.  The toothpaste is stabilized against gassing in an unlined aluminium tube by the presence of a dicalcium phosphate which exerts a hazing effect on the toothpaste.  Dicalcium phos-phate also reduces colour fading when a water-soluble dye is present.  Addi-tional haze to permit opacification of the toothpaste may be introduced by the presence of an opacifying agent, such as titanium dioxide.

Abstract: ABLUTION FAUCET                        Abstract An ablution faucet includes a wall-mounted control valve and a flexible conduit having a hand-held control unit at the end thereof.  The hand-held control unit includes a body portion from which a nozzle projects, and a lever for controlling the flow of water through the nozzle.  The body portion includes a piston which is always urged into engage-ment with a valve seat by water pressure and a piston-actuating member engageable by the lever.  Various alternative embodiments of the piston and piston-actuating member are disclosed.  The wall-mounted control valve also includes a piston which is biased to a valve-closed position by water pressure, as well as a vacuum breaker.  An alternative embodiment of the invention employs a cable disposed within the hose and connected in valve-actuating relationship between the lever and the wall-mounted control valve.  With this embodiment of the invention, actuation of the lever actuates the wall-mounted control valve, thereby avoiding the need for manually controlling the wall-mounted control valve.

Abstract: ABSTRACT OF THE DISCLOSURE Vanadium compound/orgdnometallic compound/inorganic oxide cata-lyst compositions useful for the polymerization of ethylene to polymers having an intermediate molecular weight distribution that can be predict-ably controlled by the use of a "tunable" variable are obtained by using, as the vanadium component, a mixture of about 10-90 mol percent of VOCl3 and,  correspondingly,  about 90-10 mol percent of VCl4.  The molecular weight distributions of polymers formed in the presence of the catalyst compositions are narrowed as the proportionation of VCl4 in the vanadium component is increased.

Abstract: ABSTRACT OF THE INVENTION   A fault detection system for use in power supply systems using ferro-resonant  transformers  is  presented.   A  current  transformer (17), magnetically coupled to the ferro-resonant circuit (18) of the ferro-resonant transformer (19) is used to sense the current flowing in the  ferro-resonant  circuit.   A  fault  detection  circuit  (20), powered by its own power supply (32) connected to the primary source of  power  (8),  monitors  the  sensed  current  and  signals  any significant  change  therein.   A  fault  condition  in  any  of  the secondary  circuits  of  the  transformer  causes  the  ferro-resonant current to change, and upon sensing this change, the fault detection circuit disconnects the primary of the transformer from the source of power.

Abstract: ABSTRACT A light radiating device has a transparent cylindrical tube one end of which is connected by a light conducting cable or the like to a natural or artificial light source. A plurality of transparent plates and/or reflective plates are arranged in the tube to be rotatable respectively about independent axes which commonly extend perpendicular to the axis of the tube. When used for plant culture, for example, the plates are sequentially moved to reflect incoming light so that a plant growing in a position adjacent to the device is always illuminated from an optimum direction and under an optimum distribution of light. The axes of rotation of the plates extend in different directions from each other so as to radiate light over the entire circumference of the tube.

Abstract: ABSTRACT OF THE INVENTION     A steering assistance pump includes a temperature sensor valve which communicates with an inlet duct of the pump by way of an additional, normally closed outlet passage. When a pressure relief valve responds, upon blocking of the servo steering means, the temperature of the hydraulic fluid in the system increases to such a degree that it exceeds the limit value of the temperature sensor valve. The valve thus opens to cause the pilot control pressure in the control chamber of the pressure relief valve to be reduced, whereby the pump pressure itself is also reduced.

Abstract: Abstract of the Disclosure A transducer includes a fiber optic coupler 10 having a variable coupling efficiency.  The fiber optic coupler includes  a  first  fiber  and  a  second  fiber  and  an interaction region in which light propagating in one of the fibers is transferred to the other fiber by evanescent field coupling such that introducing light into one of the fibers may cause light  to be output from both fibers. Detectors detect the  light output by  the fibers and a ratio meter produces an output proportional to the ratio of light intensity received by one of the detectors to the light intensity received by the other detector, the ratio being indicative of the coupling efficiency of the fiber optic  coupler.    In  a  first  embodiment  the  coupling efficiency varies in response to the relative position of the fibers, thereby providing a transducer for measuring displacement.    In  a  second  embodiment  the  coupling efficiency is termperature-dependent, thereby providing a transducer for measuring temperature.

Abstract: ABSTRACT OF THE DISCLOSURE          A control valve for a vehicle fluid pressure braking system includes a housing having an inlet port, an outlet port and a delivery port.  A plunger is movable in the housing to control communication between the ports.  The plunger is provided with a shoulder which carries a sealing member which engages with a seating area on the housing to provide a seal controlling communication between the aforementioned ports.  The seal includes a circumferentially extending cavity on the housing in which the body portion of the seal is received.  A pair of beads project from the body portion of the seal in opposite axial directions, so that when the seal is moved into engagement with the seating surface, one of the beads sealingly engages the sealing surface, and the axial direction forces generated thereby force the bead on the opposite side of the seal into sealing engagement with a sealing surface on the plunger.  When the plunger is moved away from the seating surface, thereby abruptly reducing the pressure level around the plunger, high pressure air which is trapped in the groove receiving the body portion of the seal may escape by deflecting the bead away from the sealing surface on the plunger, thereby preventing the high pressure fluid from forcing the seal from the groove.
