Abstract: ABSTRACT OF THE DISCLOSURE:           Disclosed is an emulsion polymerization process for the preparation of polybutadiene grafted with styrene and acrylonitrile monomers, having a very low end content or unreacted residual  monomers,  thereby  eliminating  the necessity of a subsequent stripping of the obtained product to remove the residual monomers that are known to have a negative impact on the thermal properties of the product and on the appearence of the subsequently manufactured article.          In accordance with this process, the conversion of the graft monomers is increased from the values of 92 to 94% usually obtained, to values very close to 98%, by carrying out a suplemental redox-type reaction in the latter stages of the graft  polymerization  process,  in  the presence  of  an additional aliquot of acrylonitrile and of catalytic system.

Abstract: ABSTRACT OF THE DISCLOSURE An improved friction brake system for a transit vehicle  is  disclosed.   The  conventional  friction  brake system for a transit vehicle utilizes an integral service brake and emergency-parking brake actuator.  The  service brake portion is air powered while the emergency-parking brake portion is spring powered.  It has been conventional to apply full service air brake and emergency spring brake during emergency stops.  An accelerometer switch is typi-cally connected in circuit with the service brake portion to prevent the service brake from turning on if their is sufficient deceleration.  The  accelerometer  switch  often does not react quickly enough to prevent the onset of the service  brakes.   The  present  invention utilizes  a time delay switch to delay the onset of service brakes until after the spring-activated emergency brakes react.

The valve directs hydraulic pressure to the other cylinder chamber to move the end rod so the skis rotate in a second direction when the selected connecting rod transmits a compressive force.  The selected connecting rod is able to transmit both tensile and compressive forces, and has at least one elastic member which biases a spool within the valve toward its central position.  At least one of the orifices within the valve near the spool is ellipsoidal in shape.

Abstract: The present invention involves an inner shoe material with adsorbent properties, whereby activated carbon particles are fixed as the adsorbent material by means of an adhesive substance in a punctiform manner to the side of the material facing away from the foot. The inner shoe material of the invention can be designed as inside lining, insoles, slip-soles, as inner sole of the shoe or as a covering material for the inner sole of the shoe. The inner shoe material of the invention can e.g. be used for combat boots with inte-grated C-protection or for safety boots with protection against aggressive chemicals. The inner shoe material has the advantage that it exhibits a high degree of scuff resis-tance on the one hand and the adsorbent activated carbon is freely accessible to the substances to be adsorbed, on the other.
