Abstract: ABSTRACT OF THE DISCLOSURE In a method of forming multi-layer plastics articles employing a multi-cavity injection molding machine, a combined material stream is injected from each of a plurality of coin-jection nozzle means of the machine into an associated injec-tion cavity to form each article.  The method further involves providing streams of polymeric materials to form the corre-sponding layers of the articles, and moving each material stream separately to each of the nozzle means, forming the combined stream in the plural nozzle means from the separate material streams, and injecting the combined streams to form the multi-layer plastics articles.

Abstract: ABSTRACT           An interactive audio/visual demonstration system for connection to a telephone system, comprising an audio/visual unit connected to an interface circuit.  The interface circuit decodes DTMF tones received from the audio/visual unit and in response causes implementation of one or more special features in the telephone system.  The interface circuit is preferably connected to an audio track of a video tape recorder, and to the telephone system, such as a PABX, in order to implement a highly interactive video tape presentation in response to a video tape being played on the video tape recorder.  The interface circuit is of simple construction and hence durable and inexpensive.

Abstract: ABSTRACT OF THE DISCLOSURE           In a turbine engine having a compressor with a bleed valve and a variable geometry apparatus responsive to an operational control member for regulating the flow rate of fuel supplied the turbine engine as a function of atmospheric pressure and the temperature of air supplied to the compressor corresponding to movement of a power lever by an operator to a desired operation of the turbine engine.  The power lever has an indicator member fluidtcally connected to a follower member linked to the operational control member.  The fluidic connection is responsive to operational parameters of the turbine engine and limits the rotational input to the follower member when the rate of fuel flow could cause stal-ling and the development of an unacceptable operating temperature or overspeed condition in the turbine engine.

Abstract: ABSTRACT OF THE DISCLOSURE A modified activated sludge system is provided wherein wastewater containing BOD and phosphate values is admixed with biomass-containing recycled sludge under conditions effecting sorption of BOD in the biomass, then said wastewater is subjected to aeration in an oxidation zone under conditions effecting oxidation of BOD, including a dissolved oxygen level in said zone of less than one part per million.  By such operation, considerable savings in power requirements for oxygen transfer to the mixed liquid are had, while developing and maintaining a dense non-bulking biomass having the properties of good removal of phosphate from the waste-water influent.  By operating the system at high influent throughput rate (F/M), external oxygen requirement for BOD removal is minimized.

Abstract: SINGLE PIECE HAMMER MODULE Abstract of the Disclosure A hammer module (11) for a dot matrix line printer including a cantilever mounted multi-arm hammer (23) formed from a single piece of resilient ferromagnetic material is disclosed. The multi-arm hammer (23) comprises a plurality of hammer arms (25) each including a thin spring region (51) and a thick head region (53) that lie in a plane that forms a slightangle with the plane of the base (27) of the multi-arm hammer (23). Each module also includes magnetic circuits for each hammer arm (25) formed by a common permanent magnet (13), a post (19), an arm (29) of a flux plate (15) and an arm (33) of a return plate (17). The post (19) is mounted on the tip of the flux plate arm (29). The flux plate and return plate arms (29 and 33) lie in parallelplanes located on opposite sides (poles) of the permanent magnet (13). The posts (19), flux plate arms (29) and return plate arms (33) are sized and positioned such that the tip of the posts (19) lie coplanar with the outer surface of the return plate arms (33) and such that a gap exists between each post tip and an associated return plate arms (33). The head regions (53) of the print hammer arms (25) are positioned to be attracted to the post tip and the adjacentarea of the return plate arms by the magnetic flux created by the permanent magnet (13) when coils (21) wrapped around the posts (19) are not energized. This attraction pulls the head regions 53 across the small gap created by the slight angle bend of the hammer arms (25). Thus, the thin spring region (51) of the hammer arms (25) is stressed, cocking the print hammer arms. When a coil (21) is energized, it produces a magnetic field that counteracts the permanent magnet attraction force, releasing the associated, cocked hammer arm (25). Releasing of the cocked hammer arm (25) impacts a ball (49), welded to the side of the hammer arm remote from the pole tip, against a ribbon to create a dot on a print receiving medium.

Abstract: ABSTRACT               A soft rubber seal member is molded in the cavity in the face of the valve core.  During the molding process air can escape through the slots or gates in the annular ring in the face of the valve core.  When rubber starts coming out the gate, the gates are closed off and the rubber hardens in the gates.  The valve is used in combination with a valve housing provided with an entry orifice having a diverging exit section leading to a flat annular surface against which the flat central portion of the soft rubber seal will seat when the valve is closed. This obtains a large seating area and ensures uniform valve opening pressure.

One or more subordinate processes are linked to a controlling process.  Each subordinate process has an associated overall timer.  As long as the controlling process keeps sending periodic keep-alive messages to a subordinate process, the associated overall timer is prevented from timing out.  When the controlling process stops sending keep-alive messages, the associated overall timer times out and the subordinate process is deactivated.

Abstract: Abstract:    A rotary carrousel of a filling installation includes a plurality of filling stations each equipped with a volumetric dispenser whose volume may be varied by varying its dispensing time or the stroke of a piston in a cylinder.  At least one of the filling stations includes a balance.  As a receptacle passes through the filling installation in a filling station equipped with a balance, it is first weighed empty while the corresponding dispenser is filled, and it is then weighed continuously as the material is transferred from the dispenser to the receptacle.  The actual weight of material dispensed is determined by comparing the full and empty weights of the receptacle.  This weight is compared with a set weight.  Any drift which is detected from the set weight can be corrected for subsequent receptacles passing through the filling installation by varying the volume of the material dispensed.

Abstract: LIGHT PIPE AND HEATER APPARATUS                        ABSTRACT      A GC/IR system for analyzing the constituents of a gas sample is disclosed and claimed in which a floating light pipe assembly is disposed in a bore and troughs of a heater chamber in a heater assembly.  The floating light pipe assembly has two transfer tubes and a light pipe tube that provide a completely chemically resistant path to the flow of a gas sample and carrier gas from a GC capillary column to a supplemental GC detector.  The flow path is chemically inert since no contaminating sealants are used and substantially all of the flow path is gold plated.  The light pipe assembly "floats" because it is allowed to thermally expand within the heater chamber so that high reflectivity in the IR region will be maintained as the light pipe assembly is being heated by the heater plates on opposite sides of the heater chamber.
