Abstract: TITLE:  GAME HAVING RECIPROCALLY MOVING INTERFERENCE         MEMBERS                        ABSTRACT         A game of the type having a playing surface enclosed in a housing and including a launching mecha-nism for propelling an object across the playing surface is improved by locating a target on the playing surface distal from the object launcher and interspacing between the target and the object launcher an inter-ference member.  The game includes an actuation device which continually moves the interference member recip-rocally back and forth in the path of the object.  The interference member is capable of assuming at least one position wherein it can interfere with the movement of the object and at least one position wherein it does not interfere with movement of the object Tendering it possible for the object to travel from the object launcher to the target.

Abstract: Abstract A process is described for the recovery of uranium values from phosphoric acid utilizing an alkyl pyrophosphoric acid (APPA) primary extractant. After extracting the uranium from the phosphoric acid, the APPA extractant is deactivated by heating and the uranium values stripped into a phosphoric acid strip solution containing ferric ion as a salt-ing agent.  The uranium values nay then be re-extracted directly from this stripping solution without adjustment of its concentration into a dialkyl phosphoric acid trialkyl phosphine oxide synergistic extractant from which a relatively pure yellow cake is precipitated.  A new procedure for preparing the requisite APPA primary extractants is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE:     An ABS molding material comprising a copolymer matrix A in which is dispersed a graft copolymer B. The graft copolymer B is composed of styrene and acrylonitrile as the grafting monomers on polybutadiene as a grafting base and has a mean particle diameter of from 0.2 to 0.45 µm (d50value of the cumulative mass distribution). The gel component, isolated from the molding materials, is required to have a spin-spin relaxation time of from 0.7 to 1.5 µs, so that the molding materials have a high surface gloss coupled with good notched impact strength even at low temperatures. The copolymer A can be a copolymer of styrene and acrylonitrile or a terpolymer additionally containing .alpha.-methylstyrene. The molding material can furthermore contain conventional additives. The molding materials according to the invention can be employed where great toughness coupled with high gloss is required, as in household appliances and in the automotive industry.

Abstract: ABSTRACT     A master cylinder assembly comprising two separate master cylinders is disclosed.  Pressure spaces of the master  cylinders  are  interconnected  through  outlet passages and a transfer passage, and a transfer valve is housed  within  each outlet passage.   When the master cylinders  are  inoperative  both  transfer  valves  are disposed in intermediate positions in which a limited flow can take place through both valves in both direc-tions.  This prevents hydraulic fluid from being trapped in the transfer passage which otherwise might cause a fracture to occur upon expansion with temperature of the fluid.   Each transfer valve comprises a valve member which is engageable with a seating.  The valve members may be held away from the seatings by the thickness of a film of hydraulic fluid therebetween.   In another con-struction discrete resilient projections are provided either on the seatings or on the valve members to hold the valve members away from the seatings.
