Abstract: 921,421. Agitating pulps. BLACK-CLAWSON CO. June 16, 1959 [June 16, 1958], No. 20624/59. Class 86. [Also in Group VIII] In a machine for the preparation of paper pulp by vertical circulation in a tank of generally cylindrical shape, the bottom being dished to form an outlet compartment below a screen 25 to receive reduced pulp, the circulation is effected by an impeller 20 having on its upper surface pumping vanes 35 which direct the pulp outwardly past pulping vanes 32 and over the screen surface. The impeller also carries e.g. two blades 40 much larger than the vanes 32 to project high-speed waves of pulp which, by their pressure and by the suction effect of each wave after its crest has passed, dislodge any pulp particles which have been blocking openings in the screen 25. The machine may thus be used with a screen having small openings to effect fine reduction of the pulp without clogging. The blades 40 may be 4# inches high and 13 inches long. Vanes on the inner wall-surface of the tank guide the pulp flow.

Title: Method of treating articles formed from polypropylene
IPC: B29C59/00
Filed: 1959-06-22
Abstract: Articles, e.g sheets or films, made of polypropylene are treated to render the surface receptive to ink, print, decorations, and coatings by contacting the surface with an organic ester of the general formula, <FORM:0858623/IV(a)/1> where Ar and Alk represent respectively aryl and alkyl groups, which may be substituted, and n is an integer between 1 and 3, at a temperature of from 140 to 180 DEG C. and for a period sufficient for a thin layer of the polymer to be dissolved, and thereafter treating the contacted surface with a substance which is a solvent for the ester but not for the polymer, whereby the thin layer of polymer dissolved by the ester is precipitated as a very fine powder on the surface.  Prior to contacting the surface, the whole article may be heated to a temperature just below 140 DEG C.  The organic ester may be 2-ethyl-hexyl phthalate, octyl adipate, or triethyleneglycol-2-ethyl butyrate or -ethyl-hexoate.  The ester may contain dissolved therein from 1 to 5% of polypropylene.  The solvent for the ester may be acetone, methanol, methyl ethyl ketone, or mixtures thereof.  After the treated surface has had the decoration, print, or ink applied, the powdery layer is treated to reunite the particles into a continuous coating integral with the body of the article, e.g. with hot air at temperatures above 160 DEG C. or by immersing the surface in tetrahydronaphthalene or another volatile aromatic hydrocarbon until imbibition of the surface layer is complete and then heating the article to above 150 DEG C.  The treated surface may also be coated with a solution of a resin, e.g. polystyrene.ALSO:Articles made of polypropylene, e.g. eggcups, are coated by first treating the surface of the article with an organic ester (see Group IV(a)) for a period of time sufficient for a thin layer of the polymer to be dissolved, then treating the dissolved surface with a substance which is a solvent for the ester but not for the polymer whereby the thin layer of polymer dissolved by the ester is precipitated as a very fine powder on the surface of the polypropylene, and then coating the treated surface with a solution of polystyrene or an epoxy resin in methyl ethyl ketone and/or benzene and removing the solvent.  Prior to applying the coating the treated surface may be decorated.

Title: Hydraulic brakes
IPC: B60T11/32
Filed: 1929-07-12
Abstract: 331,700. Coatalen, L. July 12, 1929. Fluid-pressure. - In hydraulic brake mechanism having a separate pressurecreating means and pipe line system for each brake or set of brakes a duct is provided for interconnecting the systems to equalize the pressures by means operative only when the pressures are effective to apply the brakes, the duct being closed between anv two systems when the pressure in one of them fails, so that the other brakes are not rendered inoperative. As shown three master cylinders 2 are arranged side by side each containing a piston 4 moved by a finger 5 on a shaft 6 turned by the brake pedal or hand lever, the pistons being moved simultaneously. The outlet pipe 7 from each cylinder is connected to a brake or set of brakes and communicates with the cylinder by passages 30 and a valve chamber 11 the valves 14 each having a needle portion 31 pressed by a spring 15 on a seating at the end of an axial passage 27 in an abutment 24. The passages 27 communicate with each other by a compensating duct 13. When the master cylinders 2 are operated the valves are lifted by the pressure acting on the cups 23, the opening movement being limited by flanges 17 formed on caps 16, and the pressure in the pipe lines 7 is equalized by the duct 13. If a leak occurs in one pipe line the valve 31 associated with that pipe-line closes, the pressure from the other cylinders acting through the bore 27 not being sufficient to overcome the spring 15. The valves may be arranged in a unitary body, closing caps 29 being spaced slightly from the abutments 24 to provide chambers communicating with the axial passages 27 and the compensating duct 13. The passages 30 connecting the cylinders with the pipes 7 are partly formed in bored bolts 32. The arrangement shown may be applied to six-wheeled vehicles or vehicles with a transmission brake in addition to wheel brakes. Each valve chamber may be connected to the oil reservoir 18 so that any oil leaking past the valve returns to the reservoir. The piston may be operated by separate pedals and one of the pedal shafts may be capable of hand operation. In modifications the compensating duct 13 opens directly into the valve chambers 11 and the needle valve 31 is omitted.
