Abstract: Polyphenylene Ethers With Imide Linking Groups Abstract Novel polyphenylene ethers with imide linking units are disclosed.  These polymers incorporate the solvent and thermal resistance of polyimides and the processability of polyphenylene ethers.  Improved physical properties over those of the prior art are obtained by incorporated meta linked ethers and/or polyphenylene oxides into the polymer backbone.  A novel process for making polymers of this type is also disclosed.  The process is unique in that the expected need of high process temperatures and/or special atmospheres are eliminated.

Abstract: - i -Abstract In the preparation of alkali metal chlorates, an aqueous alkali metal chloride is electrolyzed in the presence of at least one additive chosen from among silicates, fluorides, polybasic hydroxyalkanoic acids or their alkali metal salts, and sulfides.  The use of such additives improves the power efficiency of chlorate production by eliminating the disad-vantageous effects caused by the presence of transition metals.

Abstract: TITLE Sterile Connection Process, Apparatus and System ABSTRACT OF THE DISCLOSURE        A process, apparatus and system for making a sterile connection between thermoplastic resin tubes is disclosed.  A section of each tube is flattened and a hot cutting means is urged through the flattened sections so as to seal temporarily each tube and to provide molten tube ends.  The tubes are aligned with each other and then the desired molten tube ends are urged together to form a joint between the tubes for each pair of tube ends to be connected.  Each joint is cooled and then subjected to light stress to open the temporary seal in each tube, thereby providing fluid communication between the joined tubes.

Abstract: WINDING A PACKAGE OF TAPE     ABSTRACT OF THE DISCLOSURE         A package of tape is formed with flanged por-tions built up at the ends and a central helical traverse portion.  The flanged portions are effectively formed by a plurality of separate spiral windings each of which is interlocked with  each other  and the central traverse portion.  The central portion is formed from a plurality of helical traverses with reversal positions  slightly inside the inner edge of the flanged portions.   Either the central traverse portion or the flanged portions is built up first to form a step following which the other is built up to meet the step.  The step cannot be so high that the tape cannot traverse the step.  The extreme ends of the package is thus formed by the stable spiral wind-ings while edge drop-off from the ends of the traverse portion is limited to height of the last helical tra-verse.

Abstract: ABSTRACT OF THE DISCLOSURE         In a data transmission system where a computer side and a terminal side are connected with the aid of an optical fiber cable, unauthorized tapping of light energy from some fiber in the cable can be detected.  The transmitted signals are assumed to be shot-noise limited, i.e. the transmitted light is heavily superposed, whereby a large part of the transmitted light must be tapped off for listening.  The computer side and terminal side contain level-sensing air-cults connected to respective receiver units which send an alarm when tapping takes place.  An optical fiber relay is connected between the fiber cable and the terminal side for short-circuiting this side in case of power failure.

Abstract: CODE DIVISION MULTIPLEXER USING DIRECT SEQUENCE SPREAD SPECTRUM SIGNAL PROCESSING                              Abstract A plurality of transmitters synchronized to a common clock each transmit a data signal spread by a common bipolar pseudo-random code having a different predetermined assigned code sequence clock.  A receiver, synchronized to the clock, discriminates the signal transmitted by a predetermined transmitter from signals transmitted by the others by generating a first bipolar pseudo-random code that is a replica of the common bipolar pseudo-random code and has a code sequence shift corresponding to that of the predetermined transmitter, and a second bipolar pseudo-random code and has an unassigned code sequence shift.  The difference between the first and second bipolar pseudo-random code sequences, which is a trinary code code sequence, is cross-correlated with the incoming signals.  The cross-correlated despreads only the signal applied by the sequence having the predetermined code sequence shift.  Each receiver includes a number of correlation detectors offset from each other by a fraction of a code chip together with decision circuitry to identify cross-correlated peaks for optimum synchronization.

Abstract: ABSTRACT   The present invention relates to an improved type of wear part or tooth for earth-working machines such as excavators, loaders and mechanical buckets.  The wear part or tooth according to the invention is more specifi-cally an improved so-called cap tooth, i.e. a tooth of the type which is secured over an adapter protruding from the tool in question.  Cap teeth are highly economical in terms of material consumption since they can be worn down until only very little material remains, when the tooth must be rejected. They have, however, previously had the disadvantage that they have usually fallen out of the adapters if they have been worn down so far that the portion of the tooth cap which covered the bottom of the adapter has been eliminated. By locating the support surface of the adapter facing towards the surface of the worked earth for the tooth in two planes located at different distances from the surface of the earth we have, however, now remedied this problem.

Abstract: Abstract of the disclosure:         An apparatus for the automatic feeding of a car-rier to a laminating station has a gripper device which is fastened to two guide rods and which is movable to and fro horizontally.  Each of the guide rods is guided in a linear guide and is mounted in supports which are con-nected to one another by means of an angled cross-strut.          A pneumatic cylinder is articulated centrally to the angled cross-strut by means of a lengthened piston rod.  The gripper device grips the carrier at a predetermined distance xmin from the front edge, to transport it in the direction of a laminating station.       A sensor for detecting the front edge of the car-rier which is transported into the gripper device is located on a holding bracket fastened to a displaceable holding block.  The upper and lower gripper strips each have a perforation in the center of their bevelled strip part.  As soon as the front edge of the carrier inter-rupts the vertical beam path, the sensor generates a control pulse which closes the gripper device and which retains the carrier for the transport to the laminating station.

Abstract: GUIDED WAVE OPTICAL FREQUENCY SHIFTER              Abstract of the Disclosure This  invention  is  a  frequency  shifter  for receiving an optical carrier signal input and producing an  output  including  a  sideband  that  is  shifted  in frequency  from  the  carrier.    The  frequency  shifter includes an optical waveguide formed in a substrate of an electro-optically  active  material   such   as   lithium niobate.    A  plurality  of  electrodes  formed  on  the substrate cooperate with a signal generator to apply two perpendicular electric fields to the optical waveguide. The resultant of the two fields is a rotating electric field which produces  a rotating birefringence  in  the optical waveguide.  The rotating birefringence acts as a rotating  wave  plate, which  shifts  the  frequency  of optical signals input to the optical waveguide.  The wave plate is preferably a half wave plate, which converts all of the input optical energy into the sideband.

Abstract: Abstract of the Disclosure A control system for a refrigeration heat pump apparatus and an auxiliary heating apparatus has a two stage thermostat with the first stage normally controlling the heat pump apparatus and the second stage normally controlling the auxiliary heating apparatus.  An outdoor temperature thermostat is used to transfer the control of the auxiliary heating apparatus to the first stage when the outdoor temperature drops below a predetermined value and the heat pump is deenergized as its efficiency drops at that low outdoor temperature.

In order to improve the control and reduce the large change in temperature when the auxiliary heat is switched over to the first stage, both of the anticipation heaters of the first and second stage are connected to be controlled by the first stage during the operation of auxiliary heat by the first stage.
