Abstract: Abstract of the Disclosure An exhaust gas recirculation comprises a valve member movable in a venturi tube to restrict the flow of the exhaust gas.  The venturi tube and the valve member is sized such that flow velocity of the exhaust gas at the throat of the venturi tube exceeds the sonic velocity when pressure difference between a static pressure at the inlet end of the venturi tube and a static pressure at the outlet end of the venturi tube reaches a value which ranges from 1/2 to 1/4 of a critical pressure which is a static pressure at the throat when flow velocity of the exhaust gas at the throat reaches the sonic velocity.

Abstract: Abstract of the Disclosure Novel catalysts are provided for the polymer-ization of  olefins such as ethylene.  The catalysts consist essentially of a chromium compound supported upon an in-organic carrier containing aluminum and phosphorous moieties, at least a portion of the chromium having a valence of less tan 6.  The inorganic carrier is an amorphous precipitate of aluminum phosphorus or an amorphous precipitate containing aluminum and phosphorus moieties in an atomic ratio in the range of about 5:1 to 1:1.  The catalyses are particularly useful for polymerizing ethylene in a Particle Form Process in that the catalyst has essentially no polymerization induction period and provides ethylene polymers having a desirably broad molecular weight distribution and a de-sirably high melt flow shear ratio.

Abstract: ABSTRACT       Production line apparatus for producing concrete floors. A table for supporting a concrete receiving mold is movably mounted atop a frame.  Shaking means connected to and between the frame and the table shake the table settling the concrete within the mold.  A pair of conveyors extend from the table to convey the mold from the table.  The conveyors extend over the table but beneath the mold supporting surfaces provided on the table. The conveyors are lifted upward against the mold lifting the mold from the table.   A mold turning over device is positioned at one end of the conveyors and is operable to receive the mold and to turn the mold upside-down repositioning the mold atop a second pair of conveyors.  A hoist extends over the second pair of conveyors and is operable to lift the mold upwardly leaving the solidified concrete floor atop the second pair of conveyors.  The mold is lifted and positioned between a pair of spaced apart return conveyors which extend back toward the shaker table.  The return conveyors twist about a return axis until the mold is repositioned right-side-up.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to brushes, and more particularly, relates to a hair brush having a structure which renders it particularly useful for blow waving of hair.  In blow waving the brush is used to lift the hair away from the head while a stream of heated air is directed toward the roots of the uplifted strands of hair.  Brushes of the prior art have been found to be poorly suited for blow waving.  A majority of prior art brushes have backs or blocks which are effective to block the flow of air through the brush to the hair.  Additionally, the bristles do not allow the free flow of air, or do not allow brushing the hair in a direction lateral to the brush.  No previous block and  bristle arrangement has been satisfactory in allowing air flow through the brush, while being unaffected by the high temperature of the air being blown through. The brush according to the present invention has a back of open frame construction to facilitate the flow of hot air. Folded single bristles are inserted into holes on the front surface of the brush in a staggered relatively uniform arrangement which allows air flow, while functioning well for lateral brushing.  The bristles are relatively thick in diameter to withstand the heat of the air used in blow waving.

Abstract: Abstract of the Disclosure Disclosed is a device for synchronizing the speeds of two webs of material, the first of which moves at a constant speed and the second of which moves at an adjustable speed.  A counter, adapted to be triggered in accordance with the speed of the second web of material is coordinated therewith, the counter being adapted to be started and stopped by at least one pair of markers adapted to rotate with a reel from which the second web of material is with-drawn.  The device permits synchronization to be speedily achieved.  A first counter is set at a value (L) registered at the time of stopping and the counter is re-started whenever the value (L) is reached   A further counter, adapted to be triggered in accordance with the constant speed of the first web of material, is started and stopped by the first counter when the registered value (L) has been reached which provides a measurement of the deviation from synchronization of the speed of the second web of material.

Abstract: ABSTRACT OF THE DISCLOSURE Emulsifier-containing plastics dispersions which serve as a binder for dispersion paints, should contain polymers forming a film at room tem-perature and having a high wet adhesion.  Suitable polymers are prepared by polymerisation of olefinically unsaturated monomers initiated by free radi-cal-forming agents, especially in the presence of an emulsifier.  As emulsi-fier there is used a salt of an acrylic ester of the hydroxymethane-phos-phonic acid.  The emulsifier may remain in the dispersion ready-for-use with-out involving disadvantages for the wet adhesion.

Abstract: FILTER APPARATUS           Abstract of the Disclosure A filter apparatus wherein filter media is submerged in liquid being filtered and suction is employed under the media to increase the flow through it.  The filter media in elongated strip form is supported on an incline for movement in one direction by an endless previous conveyor.  A receiving tank for dirty liquid is above the conveyor and media with a lower tank for clean liquid below the conveyor with the sides and ends of the lower tank being constantly sealed in order to maintain reduced pres-sure therein to enhance flow through the media. Filtered liquid is supplied at the sides of the conveyor and at an end wall of the receiving tank to prevent any migration of dirty liquid into the lower tank at the periphery of the lower tank.  Advance-ment of the filter media is controlled automatically in response to variations in the pressure differential on opposite sides of the media which varies in proportion to the dirt  load of the media.  Pre-coating of the media as it enters the receiving tank is accomplished by a structure in the tank providing a transverse blinded area on the conveyor.  Drying, dewatering and/or compressing of the filter cake on media emer-ging from the dirty liquid tank is accomplished and the conveyor and media are advanced automatically.
