Title: Process for metering color concentrates to thermoplastic polymer melts
Inventor: FINTEL WILLIAM A
IPC: C09D7/80
Filed: 1989-04-21
Granted: 1995-04-18
Abstract: Continuous strands of color concentrate are metered into the feed zone of a screw-melter polymer extruder where they are cut into pellets by the shearing action of the flights of a rotating screw against the extruder housing.  These pellets are mixed within the extruder with a thermoplastic polymer to be colored and this mixture is then melted and extruded into a useful article, for example, a fiber for textile or carpeting end-use.          Additionally, color concentrates can be first formed into continuous strands and stored conveniently on a spool for subsequent metering into the polymer extruder.

Abstract: A device is disclosed for producing expanded material using cutting rollers of special design, in which the individual annular cutting rings on the cutting rollers are provided with notches in their lateral surfaces, and when the cutting roller is viewed from above, these notches are seen to be trapezoidal in shape.  The invention relates furthermore to the special configuration of the stretching system, wherein the strip-shaped non-stretched material passing through is gripped laterally by two toothed belts while at the same time the material to be stretched runs up, in its centre section, on a recirculating element, such as a round-section belt running at an appropriate speed.  This belt rises far enough out of the plane of the toothed belts that the desired transverse stretching of the material is achieved. By "expanded material" is meant a foil-like material, usually metal, in which a large number of parallel-oriented incisions are made, so that this material can then be pulled apart transversely to the direction of the incisions; as a result, the material is shortened in the longitudinal direction and the webs of material left between the incisions create a more or less three-dimensional lattice.

Abstract: ABSTRACT     A vehicle data recording system  has connections to  one  or  more  analog sensors, and stores data from the sensor(s) in a memory during a  laps  of  a  track. The  system  provides for analog/digital conversion for converting  analog  data  from   the   sensor(s) into digital  data  and triggers a procedure for storing of the data in memory.  Periods of  storing  of  the  data in  memory  are automatically started and stopped.  The system stores in memory a  set  of  data for a datum period  and  has means for storing further sets of data in a memory.  A set  of  data  stored  during  a first period  is  compared with a set of data stored during a further  period  and  one  of the  sets  of  data   is selected  for  retention in memory in accordance with a predetermined algorithm.  The retained set of  data is compared  with  the  datum  set and differences between the datum set and the selected set are output.

Abstract: A SILICON SMELTING PROCESS                          ABSTRACT           A silicon smelting furnace and a process for utilizing this furnace for the production of silicon is described.  The process involves a process in which equilmolar proportions of silicon carbide and silicon dioxide are charged to the reaction zone of a silicon furnace.  Above the furnace is placed a shaft containing particulate carbon in the amount of 2 moles of carbon per mole of silicon dioxide charged to the reaction zone.  As energy is applied to the reaction zone, molten silicon, gaseous silicon monoxide and gaseous carbon monoxide are formed, the gases passing through the shaft of carbon, converting the carbon to silicon carbide.  The silicon carbide, so formed, is combined with an equimolar proportion of silicon dioxide and the cycle is repeated.  Aside from an initial charge of silicon carbide, the feeds to the smelting furnace are silicon dioxide and carbon, silicon carbide being formed concurrently in a bed of carbon separated from the furnace reaction zone during the smelting cycle.

Abstract: TITLE            VARIABLE INTENSITY REMOTE CONTROLLED NEEDLELESS INJECTORS                     INVENTORS                  GAVIN McGREGOR                    ABSTRACT    An apparatus for injecting liquids into a body without using hypodermic needles, the liquid being eject-ed from a small orifice in a probe at a velocity which will penetrate the surface of a body against which the probe is placed.  The apparatus ejects a specific small volume of the liquid under a very high initial velocity and pressure followed by the ejection of the main charge of liquid at a lower velocity so that the liquid flows into the channel caused by the initial penetration with-out penetrating to a greater depth.  The probe is connected to a hand-held portion whose other end is attached via a flexible tube containing a suitable hydralic fluid to two remote pressure intensifiers, one of which creates the required high initial pressure for a short period of time and the second pressure intensifier provides the pressure necessary to eject the main charge of liquid at a lower velocity.  The second intensifier is synchronized electronically or mechanically to follow the initial pulse when its pressure decays to the main charge injection pressure.      The pressures created by the high pressure intensifier and second pressure intensifier are individually adjust-able for various type of situations, such as depth of penetration or skin conditions.

Abstract: COMPACT TWIN PISTON PUMP            Abstract of the Disclosure A  compact,  relatively  low  cost  twin piston pump (20) especially adapted for the pump-ing of foods (e.g. juices, puddings or particu-lates such as stews and chilies) is provided which includes quick detach yoke and clevis assemblies (108, 124, 110, 126) connecting the reciprocable pistons (100, 102) with their associated hydraulic cylinders (116, 118), thereby permitting quick cleanup of the machine (20).   A jacking screw plate (136) is used for forward mounting of the piston and cylinder assemblies (84, 86, 116, 118) coupled with the sleeves (42, 44) and associated pistons (100, 102).  This permits precise adjust-ment of the working components of the machine, while eliminating expensive bearings and heavy duty framing members.   The pump (20) is also provided with a slide plate-type valve (38, 184) for controlling output of product from the pump (20).   In one valve embodiment (184) a two-part metallic slide plate assembly (192, 200) is sand-wiched between a pair of apertured nylon plates (186).  One of the slide plate parts (200) is of lesser thickness than the primary part (192), so as to permit limited fore-and-aft movement of the part (200) for sealing purposes.  A unique hy-draulic system employing a master pressure reduc-ing valve (222) and a slaved pressure reducing valve (224) is employed for creating a pressure differential across the part (200) in order to bias the same for sealing purposes.

Abstract: The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added. The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800. The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologically acceptable. In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.

Abstract: A pipe coupling has a cylindrical housing which is split in the longitudinal direction and has inwardly bent end walls and a steel insert sheet of analogous design bridging the gap in the housing. With the aid of a closure with tensioning screws, the housing can be constricted in the manner of a pipe clip, such that a sealing sleeve positioned between the housing and a pipe is compressed in the circumferential direction and brought to bear on the pipes to be sealed off. The closure is offset in the circumferential direction with respect to the housing gap, and the end section of the housing projecting through the region of the tensioning screws is overlapped by a slideway anchored on the other end section. By this means, dimensional stability is increased without increasing the wall thickness, or the constrictability of the housing is guaranteed despite an increased wall thickness.

Abstract: The invention relates to a method and arrangement for controlling a pressure fluid operated apparatus (22) by means of a control unit (1) and valve system (7). The motions of the control elements (3, 5) of the control unit (1) manipulate the valve devices (7a, 7b) of the valve system (7), so that pressure fluid can flow and affect the apparatus (22) by moving its outlet (22a). The motion (D; B', C') of the outlet (22a) of the apparatus (22) is coupled back to the control unit (1) so that the back-coupled motion eliminates the motion (B, C) of the control members (3, 5) of the control unit (1). As a consequence, the motion of the control elements (3, 5) is essentially stopped, and pressure fluid can flow, during the operation of the control unit (1), to the apparatus (22) and affect the device with its pressure. The stopping of the control unit (1) causes the back-coupled motion of the apparatus to shift the control members (3, 5), and consequently their control over the valve devices (7a, 7b) of the valve system (7) ends, and the apparatus (22) stops.
