Abstract: THERMOFORMING MACHINE WITH AUTOMATICALLY MECHANICALLY OPERATED WEB STRIPPING ELEMENT     ABSTRACT OF THE DISCLOSURE         In differential pressure synthetic plastics thermoforming machinery, mold support assemblies mounted on a frame have relative movement between a mold open and a mold closed position.  Power operated mechanism is pro-vided for axially moving at least the female mold support assembly, and the female mold on the assembly which carries a stripper element mounted for relative movement with the mold.  Mechanism is provided for automatically latching the stripper element to the frame as the female mold moves to-ward mold closed position, and abutments are provided on the mold support assembly and latch for automatically unlatch-ing it only after the female mold has withdrawn a predeter-mined distance in its movement toward mold open position.

Abstract: Abstract of the Disclosure A double heterostructure laser having a pair of opposite-conductivity-type, wide bandgap cladding layers separated by a narrower bandgap active region is characterized in that the active region includes a low-loss waveguide layer and contiguous therewith a narrower bandgap active layer in the form of a narrow strip which extends along the longitudinal (resonator) axis of the laser.    Suitable lateral current confinement means, such as reversed biased p-n junctions, are provided to constrain pumping current to flow in a narrow channel through the active layer.  Lasers of this type exhibit relatively high pulsed power outputs (e.g., 400 mW), linear L-I characteristics, stable fundamental transverse mode and single longitudinal mode oscillation.  In another embodiment the surfaces of the waveguide layer adjacent the active layer are provided with distributed feedback gratings.  Also described are techniques for shaping the active layer without the introduction of debilitating defects therein, as well as procedures for LPE growth on Al-containing Group III-V compound layers Which are exposed to processing in the ambient.

Abstract: TEST SIGNAL GENERATOR FOR SIMULATED SPEECH     Abstract of the Disclosure A test signal generator for pseudo-simulated non-intelligible speech.  The generator comprises first and second ROM's controlled by first and second address counters driven by a single clock.  The first ROM generates digital samples which when decoded produce a random signal having a gaussian amplitude distribution.  The second ROM also generates digital samples which when decoded produce a modulating signal having a power spectrum substantially equal to that of the modulation envelope of speech and a wave shape that results in a gamma amplitude distribution of a gaussian amplitude distributed signal.  Each cycle of the modulating signal has an identical wave shape but a randomly varying wave period.  The output of the second ROM is demodulated in a first digital-to-analog converter and the demodulated output is used to amplitude modulate the output of the first ROM in a second digital-to-analog converter to provide an output signal which is then passed through a band-shaping filter to provide the pseudo-simulated non-intelligible speech at its output.    - i -

Abstract: A b s t r a c t A device for the contact-less measuring of the velocity of and/or the distance covered by a vehicle (W) with the aid of three transmitters (F1, F2, F3; F?, F?, F?), arranged along and/or at the ends of a track (J), which generate two so-called standing waves running in opposite directions.     These standing waves are detected and analysed by means of a measuring device (Q) which is located in a vehicle (W).   The frequencies (f1, f2, f3) are different, frequency multi-pliers (M2, M3) being advantageously used in two transmitters (F2, F3; F?, F?).       The method of measuring by means of this device makes it possible to detect the velocity and/or the distance covered much more accurately and is also suitable for vehicles without wheels, that is to say, for example, for suspension railways and air-cushion vehicles.

Abstract: ABSTRACT     Raw shale oil containing precipitable compounds such as iron  and  arsenic  are preheated  to  below the precipitation temperature  and  then mixed  with hot recycled  hydrogen  and oil,  and  catalytically  hydrocracked  in  an  ebullated  bed catalytic reactor.  The metal compounds are deposited on the catalyst in the reactor, from which they are withdrawn along with  used  catalyst which  is  replaced  with  fresh  catalyst.       The reactor effluent is further hydrotreated in a fixed-bed catalyst reactor, usually at extreme conditions of 780-830°F and 1800-2500 psig hydrogen partial pressure.  The resulting material is phase-separated and distilled to provide jet and diesel  fuel  oil  product  meeting  military  specifications, while clean hydrogen and heavy oil streams are reheated and recycled to the ebullated bed reactor.

Abstract: Abstract There is described a collection of monoclonal anti-bodies the members of which being directed against human leucocyte interferon (HLI) which is natural or obtained by recombinant DNA technology. The mono-clonal antibodies are preferably secreted by different hybridomas. It has been shown that individual mono-clonal antibodies are not mutually inhibiting,  i.e. bind together to HLI while others are mutually in-hibiting,  i.e. do not bind together to HLI. It has been shown furthermore that the collection consists of groups of antibodies/members of which recognize different epitopes (antigenic determinants) of HLI. Each a member of the different groups of antibodies can be used for a solid phase-sandwich test for HLI. In addition an antibody of the collection can be used for the purification of HLI by affinity chromatography.
