Abstract: Abstract of the Disclosure A fast circuit switching system that establishes a circuit for each packet-sized data communication.  Information is conveyed from a number of communications modules in source channels to a number of port controllers and to a network.      Information is conveyed from the network to destination channels.  Each communications module includes a transmitter that transmits in an associated source channel, circuit setup request signals defining destination channel, and also transmits data.  Each port controller stores one of a number of status words defining the availability of the destination channels and each of these status words is cycled to each port controller.  A port controller responds to one of the circuit setup request signals and to subsequent data, when one of the status words cycled thereto defines as available a destination channel defined by the circuit setup request signal, by transmitting the circuit setup request signal and the subsequent data to the network.  The network responds to circuit setup request signals received from the port controllers by transmitting data received from the port controllers to the destination channels defined by those circuit setup request signals.

Abstract: ABSTRACT OF THE DISCLOSURE Material dispenser apparatus includes a dispenser roll and dis-penser roll cleaning brush mounted within the bottom discharge opening of a material receiving hopper for direct contact by the material in the hopper. The brush, being directly disposed to the material in the hopper, aids in displacing the material in the hopper toward the dispenser roll and compact-ing the dispenser roll with such material. Also, the brush clears the material from the dispenser roll as the brush and dispenser roll come into contact with each other. The speeds of rotation of the brush and dispenser roll are desirably each controlled independently of the other to permit them to be simultaneously rotated in the same direction but at different rpm for controlling the rate and size of material being dispensed. A material agitator may be provided in the material receiving hopper for working the material down within the hopper into contact with the surfaces of the dispenser roll and brush which are exposed to the material in the hopper. The material agitator includes a plurality of circumferentially spaced longitudinally extending agitator bars each of different lengths and supported at different radial distances from a rotating support shaft which may be driven by the same motor that drives the dispenser roll, but at a slower rpm.

Abstract: ABSTRACT         An adjustable bolster block to be disposed between the ram or bed of a brake press and a die is disclosed which permits crowning to compensate for deflection of the brake press under loading.  The bolster block includes a double wedge support coupled to the ram or bed and a die holder to hold the die,  Two wedges are sandwiched intermediate the wedge support and die holder, one on each side of a central plane passing longitudinally through the bolster block.  The wedges have cam surfaces which engage complementary cam surfaces on each of the wedge support and die holder.  Movement of the wedges toward or away from each other varies the spacing between the wedge support and die holder.  The wedges can be bent in directions towards and away from each other symmetrically about a central plane to vary their separation along their length and to thereby vary the spacing of the die holder from the wedge support along their lengths so as to crown the die holder, The symmetric configuration minimizes net bending moments acting on the die holder tending to bend or twist the die holder in directions normal to the central plane.

Abstract: ABSTRACT OF THE DISCLOSURE    Cookies having an extended shelf-stable soft or chewy texture throughout the cookie are prepared by coextruding an inner adherent cookie dough bakeable to a soft or chewy texture and an outer non-adherent cookie dough bakeable to a soft or chewy texture.  The inner dough  comprises  a  liquid  humectant  in  an  amount sufficient  to  impart  a  shelf-stable  soft  or  chewy texture to the baked outer cookie dough in excess of that attainable by baking the outer dough alone to a shelf-stable soft or chewy texture of the same moisture content.  The coextrudate is severed into pieces to enrobe the inner cookie dough and the pieces are baked to a moisture content of at least about 6% by weight of the cookie.  The outer non-adherent cookie dough, while being  bakeable  to  a  soft  chewy  texture,  possesses sufficient cohesiveness and firmness so as to render the coextrudate formable into cookie dough pieces on a mass scale.  The use of the non-adherent cookie dough to enrobe the adherent filler dough avoids sticking of the inner adherent cookie dough to oven bands and cookie dough cutting equipment.

Abstract: ABSTRACT OF THE DISCLOSURE         In this method for treating circulatory fluid constituents, first a selective switching means switches the upstream side of a first circulatory fluid treatment device to receive from a source a flow of circulatory fluid, and switches the downstream side of the first circulatory fluid treatment device to send to a destination the flow of circulatory fluid.          Next, the selective switching means, while maintaining the switching of the flow of circulatory fluid to the destination from the downstream side of the first circulatory fluid treatment device, switches the upstream side of the first circulatory fluid treatment device to discommunicate with the flow of circulatory fluid from the source, further switches the upstream side of the second circulatory fluid treatment device to receive the flow of circulatory fluid from the source, and further switches the downstream side of the second circulatory fluid treatment device to communicate the flow of circulatory fluid to the upstream side of the first circulatory fluid treatment device.  Finally, the selective switching means, while maintaining the switching of the flow of circulatory fluid from the source into the upstream side of the second circulatory fluid treatment device, switches the downstream side of the first circulatory fluid treatment device to intercept sending the flow of circulatory fluid to the destination, and further switches the downstream side of the second circulatory fluid treatment device to send to the destination the flow of circulatory fluid.  An apparatus practising this method is also disclosed.
