Abstract: A process for controlling a multiple stage drawing machine that implements a direct non-sliding drawing process provides for set-up and production to be automatic and for the variables necessary for process control, especially material speed and applied force, to be derived without establishing contact between the stock material and a sensing device.

Abstract: The plastic substrate portion of the part is formed by a first injection of plastic into a mold, so as to adhere to an overlying sheet of coverstock material. A portion of the coverstock is not initially adhered to the substrate. A second injection of plastic forms the undecorated portion of the part, and bonds to the substrate portion to form a unitary plastic panel. In the course of contacting the substrate portion, the plastic from the second injection folds and hides the non-adhered portion of the cover stock, thereby forming a neat, clean split line.

Abstract: An arrangement is provided in an air preheater for mounting and adjusting the axial seal plates in relation to the rotor using a reduced number of adjustable mountings and replacing the remaining adjustable mountings with adjustable compression stops. These adjustable compression stops engage but require no attachment to the axial seal plates. This reduces the work necessary in the limited space between the air preheater housing and the axial seal plates thereby reducing costs and facilitating installation and replacement.

Abstract: A process for producing high-quality polycarbonate grade bisphenol A directly by removing phenol from the adduct crystal of bisphenol A with phenol via a gas-solid reaction at low temperature comprises directly feeding the adduct crystal into a vacuum or pneumatic dephenolizing device under vacuum a inert gas stream, controlling the temperature of the adduct crystal below its melting point, decomposing the adduct crystal into gas phase and solid phase, removing the gas phase phenol and condensing phenol for recovery, well leaving the rest being the desirable bisphenol A. The process possesses easy operation, short procedure, low energy consumption, and high purity and good color of bisphenol A obtained. Bisphenol A produced according to the process of the invention may be used as the raw material for producing polycarbonates for optical use.

Abstract: The single tapered die mount employs a radially inner surface at an angle to the axis of rotation of the die mount, die and die holder. The radially inner surface of the die mount acts on an annular shoulder of the die to support and position the die in the die holder. The die mount of the invention is located between the radially outer surface of the die and the extended lip of the die housing. In the preferred embodiment of the invention, the radially inner surface of the die mount in contact with the radially outer surface of the die shoulder has an angle of a modified Morse taper. The radially outer surface of the die shoulder is machined to a matching angle.

Abstract: A swing-arm sootblower for a rotary regenerative air preheater is mounted to sweep across the air preheater rotor at a constant speed or angular velocity. A constant speed motor is attached through a speed reducer to a drive sprocket. A chain drive turns driven sprocket which is connected to the rotatable mounting shaft for the sootblower lance or arm. Limit switches are tripped at the ends of the arc of travel of the lance by a trip arm mounted on the drive sprocket to turn the motor off and to close a valve for the sootblowing medium. The speed of the lance can be adjusted in general or at particular points in the art of travel.

The ribbon is defined by turns of increasing diameter extending from the minor to the major diameter end of the core. A conical feed housing surrounds the ribbon.

Abstract: A kraft black liquor gasification system is provided with a hot flue gas generator which serves both as a means for generating a hot flue gas to warm-up the gasifier in preparation for start-up and as a means for generating an inert purge gas to purge the gasifier of flammable gases in the event of an emergency trip of the gasifier. A control system controls the operation of the burner during warm-up in response to the gasifier temperature and during the purge in response to the purge gas composition and temperature.

In the nozzle assembly, the outlet end of the nozzle is biasable towards the inner surface of the rotatable screening drum (7) of the separation process, and a roller or pad is provided on the nozzle to contact the drum and maintain a substantially constant distance between the the nozzle outlet and the drum surface. The outlet end of the nozzle can be swivable relative to the feed means of the nozzle.

Abstract: An air lift pump for wet particulates has a plurality of transport tubes and air injectors disposed in a central column for transporting particulate matter from a lower elevation to a higher elevation. The central column has a closed top and an open bottom. Each tube has a lower, intake end and first and second air injectors comprised of a housing disposed around an air injection section of the transport tube in which is mounted a first or second air jet, respectively. Each air jet may be composed of either a plurality of circular ring members or a coiled member. The ring members and the coiled member have a substantially triangular-shaped cross section wherein the base of the triangle defines the exterior surface of the air jet. The ring members and coiled member form a plurality of circular slots or a coiled slot, respectively, having substantially trapezoid-shaped cross sections.

Abstract: The present invention teaches multiple branch peptide constructions (MBPCs) formed from a core matrix to which is attached peptides derived from the V3 loop of the envelope glycoprotein of HIV-1, and including the amino acid sequence GPGR (SEQ ID NO: 5), preferably in the form GPGRAF, but which peptides preferably are free of the amino acid sequences IGPGR (SEQ ID NO: 1) or IXXGPGR (SEQ ID NO: 3), where X is an amino acid residue, and the use of such MBPCs as a therapy against HIV. The MBPCs prevent virus/cell infection and cell-to-cell virus transmission between CD4.sup.+ cells and HIV without hindering the immunogenic role of the CD4.sup.+ cells. Moreover, the MBPCs are effective in blockading both CD4 receptors on lymphocytes and macrophages and GalCer receptors on colon epithelial cells. These MBPCs are not immunogenic nor toxic at doses of their intended use (<[10.sup.-3 M]), thus allowing for them to be used therapeutically.

Abstract: A butter pat dispenser including a rectangular box-like container having a U-shaped cover and a rectangular plate-like member. An end wall closes the first end of the container and the second end defines an opening. In one embodiment, the first end of the plate is pivotally mounted to the side walls defined by the legs of the cover. In another embodiment, side edge portions of the plate are received in longitudinally extending grooves in the interior surface of each of the side walls. A driver and a pusher provide means for advancing an end of the stick of butter out of the opening for slicing. The pusher comprises a pusher member disposed in the container and a nut or threaded sleeve disposed exteriorly to the container. The driver comprises a drive rod which is rotatably mounted to the top wall of the container and a knurled knob which is rotatably mounted to the end wall of the container. One end of the drive rod extends into a cavity in the knob.

Abstract: A feeder station for apparatus for collating printed sheets includes a mechanism for imparting motion to individual sheets prior to the time the sheets are engaged by a pusher mechanism which propels the stack of collated sheets being formed along a conveyor. The mechanism for imparting motion to the individual sheets in the feeder station contacts the sheets within a region which is directly aligned with the path the engaged portion of the sheet travels in moving from a feed magazine to the feeder station under the influence of a gripper device, the sheet thus being transferred directly from the gripper device into contact with the motion imparting mechanism.

An elastomeric band around the rollers having at least one twist on a top surface provides for edge justification of documents against the guide rail.

Abstract: A filter module for filtering a flow of fluid employs a base member which either mounts a blanking plug or a diverter valve module. The plug is replaced by a diverter valve module for use with those engines that require an auxiliary source of low pressure fuel. A solenoid valve is housed in the module. A pressure regulator valve positioned in the valve module maintains a backpressure in the filter assembly to insure that there is sufficient head to drive the flow of fuel to the engine.
