Abstract: Abstract Hands-free control circuitry for a mobile radiotele-phone is described that allows hands-free voice communi-cations in a vehicular environment having a high level of ambient background noise.  The hands-free control cir-cuitry includes switches in the audio path from a micro-phone to the radio transmitter and the audio path from the radio receiver to a speaker, where, at all times, one audio path is closed to pass audio signal and the other audio path is open to block audio signals.  The presence or absence of audio signals from the mobile party via the microphone and land party via the radio receiver is determined by separate detecting circuitry including a logarithmic amplifier, envelope detector, valley detector and summing circuitry, and comparator.  Whenever the envelope of the audio signals exceeds its minima by an amount greater than a reference voltage, the detecting circuitry generates an output signal indicating that audio signals have been detected.  Control logic is coupled to the output signals from the land party and the mobile party detecting circuitry for closing and opening the switches in the audio paths.  One party may break-in on the other by closing his audio path and opening the other's audio path.  The audio path of a speaking party is closed if the output signal from his detecting cir-cuitry indicates that audio signals have been detected and the output signal from the other party's detecting circuitry has been absent for a predetermined time interval.  The inventive hands-free control circuitry provides for fast break-in by either party, while minimizing spurious path switching.  Furthermore, the hands-free control circuitry may also be utilized in landline telephone applications.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for cutting material from a workpiece by means of a laser beam.  A laser resonator emits an essentially coherentbeam of electromagnetic radiation having at least partial linear polarization.  A converting means receives the linearly polarized laser beam and converts the beam into an essentially coherent beam of electromagnetic radiation having at least partial circular polarization.  A directing means ensures that the circularly polarized beam is directed against the workpiece at the point of the desired cut.  A conventional focusing means and axially directed gas jet may be added to enhance the cutting of the laser beam.

Abstract: Abstract of the Disclosure A sanitary fan spray nozzle is disclosed together with its method of manufacture.  The nozzle includes a passage extending from the interior surface of the tube to an exterior surface thereof.  The passage has a relatively large diameter for a portion thereof between the interior surface of the tube and a point within the tube walls.  The passage then narrows and is intersected by an arcuate groove having a lengthwise dimension which is substantially parallel to the longitudinal axis of the tube.  The width of the arcuate groove is smaller than the diameter of the larger portion of the passage.  The nozzle is formed by a method which includes drilling a pair of diametrically opposed small pilot holes through the tube, drilling completely through one of the pilot holes and a portion of the opposing hole with the bit having  a  larger diameter than the pilot holes.  An  arcuate groove is then cut within the exterior surface of the tube.  The opposite hole is later plugged.

Abstract: Case 2799 THYRISTOR TAP CHANGER ARRANGEMENT    ABSTRACT OF THE DISCLOSURE          A transformer tap changing apparatus for arcless tap changing uses thyristors as the main switching means.  The apparatus has a number of taps on the secondary winding of a transformer.  Two branch circuits, each having a movable contact at one end connect the same tap or adjacent taps to a load.  Each branch includes series connection of a reactor and oppositely poled, parallel connected thyristors which control current flow through the respective branch. The apparatus does not require an interrupter switch connected between the branch circuits.  When one of the movable contacts is to be moved to raise or lower the voltage, the thyristors in the branch circuit having the movable contact have the gating voltage removed and they stop conducting at the next current zero.  The movable contact can then be changed to another tap with no arcing, and then the gating voltage is re-applied to the gate electrodes.

Abstract: "Multi-way Valves for Pumps for Conveying Heavy Flowable Materials"     ABSTRACT OF THE DISCLOSURE     The valve has a shutter mechanism which is movable within a housing and is provided at one end with at least one inlet which is movable across one or more housing openings and at the oppposite end with an outlet surrounded by a sealed contact joint which is movable across a delivery pipe opening in the housing,  This sealed contact joint surrounds the delivery pipe opening in the housing and contacts either the inside wall of the housing or a face plate arranged on the inside wall of the housing in all intermediate and final positions of the shutter mechanism.  With the aim of reducing wear and producing a permanent seal, the sealed contact joint is in the form of a compressible sealing ring with a slotted or kidney-shaped cross-section which serves to wipe the flat and smooth face plate or inside wall of the housing.  Moreover the compressible sealing ring is loaded with the internal pressure of the shutter mechanism and is supported outwardly by a flange surrounding the outlet and extending in the conveying direction.

Abstract: Abstract The objects of the invention are a process and appliance which ensure that a uniformly good quality of soft-ice can be produced at all times from the same soft-ice starting materials. Such a process is described wherein the liquid mixture is frozen, and the frozen mass (7) placed in the appliance (1) which is then closed gas-tight before the mass is subjected to a positive pressure of gas. The frozen material (7) is then comminuted and thoroughly mixed under gas pressure. Finally, the soft-ice is removed from the appliance. The mix is frozen in its original, liquid form. When soft-ice is to be made,the completely frozen mix is placed in the domestic soft-ice machine in the same container (5). The space in which the soft-ice is to be made is closed off air-tight and gas-tight in order that the gas or air needed to produce the "soft" effect can be introduced at the appropriate moment. There then follows the comminution of the frozen mix by means of the knife (16), which simultaneously provides thorough mixing of the resultant soft-ice. The neces-sary relative movement for this can be achieved equally well via the frozen mix or the tool. Simultaneous movement of mix and tool is also conceivable as a means e.g. of simultaneously intensifying the comminution process and the mixing process.     (figure 1)

Abstract: ABSTRACT          A method for the production of polypeptides utilizing a polymer of charged amino acids and an exopeptidase.  A       DNA sequence coding for the charged amino acid polymer is inserted adjacent to one end of the polypeptide gene.  The polypeptide-charged amino acid polymer fusion product is removed from most contaminents by selecting for the charged amino acid polymer during a first isolation step.          Next the charged amino acid polymer is hydrolyzed using an exopeptidase which leaves the polypeptide active.  A second isolation step removes the polypeptide from any remaining contaminents.  An example using polyarginine and carboxypeptidase B to produce urogastrone is included.

Abstract: SERIAL RING ACTUATOR               Abstract of the Invention A linear solenoid device comprises a cylindrical armature or plunger freely movable within the central opening of a stator which comprises a cylindrical coil wound between a pair of annular end pole members and surrounding one or more intermediate annular pole members.  The intermediate pole members are axially spaced and aligned with the end pole members by a bobbin which preferably is injection molded.  The armature has plural axially spaced and aligned annular pole members concentrically arranged within the central opening of the single cylindrical coil.  The magnetic stator and armature poles take the form of rings which are dimensioned and arranged so that the magnetic flux generated by the coil passes in a series path alternately from the stator to the armature rings and then through a cylindrical magnetic casing which forms a magnetic flux path between the end pole members.  The armature includes a support body of non-magnetizable material which may he plastic and can be injection molded.  The support body has annular bearing surfaces formed between the armature rings for maintaining annular air gaps between stator pole member and armature rings and for positioning the armature within the central opening.
