Abstract: High molecular weight polyester resins such as polyethylene terephthalate, are sometimes produced from low molecular weight polyester prepolymers having the same composition by solid state polymerization. The low molecular weight polyester prepolymers which are used in such solid state polymerizations are normally prepared by conventional melt polymerizations and are generally in the form of pellets or chips. It has been unexpectedly found that solid state polymerization rates can be greatly improved by utilizing polyester prepolymers which are in the form of porous pills. By utilizing polyester prepolymers that are in the form of porous pills, higher molecular weights can be achieved after shorter solid state polymerization times. 
     The present invention specifically relates to an improved process for solid state polymerizing a polyester prepolymer into a high molecular weight polyester resin comprising heating the polyester prepolymer to an elevated temperature which is sufficient to induce solid state polymerization, wherein the polyester prepolymer is in the form of porous pills. The porous pills utilized in such solid state polymerizations generally have a density within the range of about 70% to about 99% of the density of solid polyester pellets which are comprised of the polyester prepolymer and weigh from about 0.0005 to about 0.5 grams.

Abstract: Method of producing a composite plastics structure which has stressing regions and zones of reduced stressing and in particular in the stressing regions a stress distribution with preferred direction of the tensile stresses, plasticised material being shaped with the aid of a mould corresponding to the composite structure. First of all the stressing regions of the composite structure are determined (for example assisted by the means of computer technical-mechanics and the method of finite elements). Then, taking into consideration the stressing regions and the regions of reduced stressing, a layout plan is prepared for the construction of the composite structure from a strand or from a number of sections of such a strand of plasticised material. With the aid of at least one extruder, at least one strand of plasticised material which has increased tensile strength values in the direction of the strand is produced. This strand or the sections of this strand are put together in accordance with the layout plan to form the composite structure, the regions of the strand being integrally united with one another. An apparatus for carrying out the method is also specified.

Abstract: In a polarization diversity receiver comprising demodulator circuits (31, 32) which may have a restricted dynamic range, input intermediate frequency signals are supplied from optical detectors (16, 17) to automatic gain controllers (21, 22) for producing output intermediate frequency signals with their intensities adjusted optimal to the respective demodulator circuits irrespective of a fluctuation which may appear in a polarization state of a signal beam supplied to the receiver. supplied with the output intermediate frequency signals, the demodulator circuits deliver baseband signals to a signal combiner (43) with their intensities adjusted so as to have a ratio which is equal to a square of a ration between intensities of the input intermediate frequency signals. This makes the receiver have a reception sensitivity which is least deteriorated by polarization diversity. Each automatic gain controller comprises a variable gain adjuster (26, 28) which may be either feed forward or feedback controlled by a control signal produced by an intensity detector (25, 27). Each demodulator circuit comprises another variable gain adjuster (41, 42) controlled by the control signal.

Abstract: A cylindrical casing (12) accommodates an operator piston (24) and a power piston (28) separated by a fixed barrier (18) which serves to define with the former a reservoir and with the latter a power chamber. A piston rod (30) affixed to the operator piston (24) extends through the barrier into manual brake actuating relation with the power piston (28). Hydraulic fluid under pressure is introduced to the reservoir from which it flows through barrier passages (70), past a check valve (73), into the power chamber and out through venting ports (82) formed in the piston rod. To apply vehicle brakes linked to the power piston, the operator piston (24) is manually propelled toward the barrier (18), and the power piston (28) is thus forced away from the barrier (18) by the piston rod (30), resulting in rapid transfer of hydraulic fluid from the reservoir to the power chamber. The venting ports (82) then close, such that the power chamber is pressurized to exert a brake power assisting hydrostatic force on the power piston. Also preferably included are provisions (34) for developing feedback forces to afford operator brake feel.

Abstract: An (improved) direct coupled logic (DCFL) circuit achieves a full output swing of almost 0.7 volts with GaAs, and yet requires only two reference voltage levels (+V, -V). The circuit has a first switching FET (T10) supplied by a current source (T9, K1), an output line (2), and an output circuit (D3, T11) which effectively decouples the output line from the first FET (T10) and connects it to a low voltage reference when a logic "high" signal is applied to the input of the switching transistor. The output circuit consists of a voltage drop element, in the form of a Schottky diode (D3), in series with a second FET (T11). The gates of the two FETs (T10, T11) are connected in common, and the circuit output (2) is taken from the juncture of the Schottky diode (D3) and the second FET (T11). The circuit produces a low state output signal much closer to the lower reference voltage than prior circuits employing only two reference voltage levels (+V, -V), with a correspondingly higher output voltage swing, noise margin and operating temperature range.

Abstract: Radiation detectors (20) of a computed tomography scanner (10) each have a radiation receiving face (34) which is larger than a photosensitive face (30) of a photodiode (22). Lead wires (28) connect the ends of the diode photosensitive surface to terminals (26). A scintillation crystal (32) has an overhanging portion (38) which overhangs at least the interconnection between the lead wires and the photosensitive face to protect the adjoining areas of the photosensitive face fro incident radiation. This enables the radiation receiving surface to be larger than the photosensitive surface. The crystal is either undercut to define the overhanging area or a section of light pipe (60) is provided between the photosensitive surface and the crystal. Increasing the radiation receiving face decreases rotor ripple artifacts. Decreasing the photosensitive face area decreases diode capacitance and increases resistance which improves amplifier performance.

The   process comprises admixing copolymer, monomer, at least 15 ppm of catalyst and 25-2500 ppm of an organic peroxide having a half-life of from about 1 minute to about 120 minutes at 150°C, and admixing at a temperature above the melting point of said copolymer for a period of time that is at least 4 times the half-life of the organic peroxide so as to obtain a uniform distribution of monomer, catalyst and peroxide in the copolymer. The resultant grafted copolymer may then be extruded into a shaped article.
