Granted: 2002-01-15
Abstract: A method aid apparatus are shown for forming a flange on pan end of a plastic pipe liner of the type used to line a tubular member. A reinforced disc hawing a rigid portion and an elastomeric portion is placed about the liner exterior and moved into position flush with the flanged end of the tubular member. A retaining ring is placed about the reinforced disc and the disc and liner exposed end are heated to render the materials malleable. A forming unit is then used to apply force to the liner to flow tine liner into a reformed shape having a greater external diameter than the remainder of the liner. The forming operation also bonds the reinforced disc to the reformed liner end to further resist any tendency of the liner end to be retracted into the interior of the tubular member.

Abstract: A railcar suspension assembly at each end of a railcar eliminates the use of a car body bolster and allows payload forces to be carried at railcar side sills into a cross-extending box-like section. The section has bearing wear plates attached to it directly over the truck sideframes so that the forces pass directly downward, into the bearing assembly which is attached to the bolster ends. The forces then are transferred into a conventional sideframe. The loading path allows the bolster to be made with a lightweight midsection and conventional ends having friction shoe pockets.

Abstract: A method of infecting insects is disclosed; the method utilizes a form of a baculovirus which is highly efficient at establishing infection and is normally destined to become occluded within the polyhedrin or granulin - Pre-occluded Virus (POV). Specifically, the POV as derived from a polyhedrin-minus or granulin-minus (lacking a functional polyhedrin or granulin gene) baculovirus is fed to insect larvae per os resulting in high infection rates. The discovery of the POV form of polyhedrin-minus baculoviruses was essential to our invention of the novel method of infecting insect larvae per os using the POV form of polyhedrin-minus baculovirus, and as such is also disclosed.

Title: Dose modulation and pixel deflection for raster scan lithography
Inventor: ABBOUD FRANK E
IPC: H01J37/302
Filed: 1994-05-06
Granted: 2000-11-14
Abstract: A raster scan lithography system is modified so that the duration of illumination (dose modulation) for particular pixels is varied to lie between the full on and full off normally used. For instance, three levels of pixel intensity are provided, 100 %, 70 % and 30 % (in addition to off which is 0 %). The 30 % and 70 % pixels are used along the edge of a feature so as to locate the edge (52, 54) when written in between the lines of the cartesian raster scan grid. Thus the edges of the feature ace moved off the grid, without the need for multiple passes. This pixel dose modulation uses three preset delay lines (30) determining dwell times for each pixel on a pixel-by-pixel basis, as defined by a two (or more) bit deep memory file associated with the pattern to be written. Additionally, the pixel center locations are directly moved off the grid by deflecting the beam as it scans certain pixels located along feature edges. The amount of deflection is controllably variable to achieve various edge locations. This deflection is used by itself or in combination with die modulation, and is implemented by an electrostatic deflector in the beam lens for an E-beam system.

Abstract: The present invention provides a rotary disc for use with a phase-contrast haploscope which is compact and small-scaled, provides a high-speed changeover using a single motor without mutually synchronizing driving portions, and is convenient for use, and provides such a phase-contrast haploscope.     A phase-contrast haploscope includes a disc case and left-and right-hand projectors.  Left- and right-hand look-through holes are formed in a front plate in its lower half portion. Left- and right-hand beam emitting holes and left- and right-hand beam incident holes corresponding to the left- and right-hand look-through holes are formed in the front plate and the rear plate, respectively, at desired opposed positions.  A motor driven rotary disc is contained in a rotatable manner in the disc case.  The through holes and project-through holes sweep out respective concentric circular paths of different diameters and pass at a high rotational speed between the left-and right-hand look-through holes and the through window and between left- and right-hand beam emitting holes and left- and right-hand beam incident holes in such a manner as to instantaneously coincide therewith.  The left- and right-hand projectors takes in beams from the left- and right-hand beam incident holes, irradiates the lantern slides with the beams through appropriate beam transmitting means and projects projecting beams having passed through the lantern slides onto the plane of projection.

Abstract: A benzene-rich gasoline stream is alkylated with higher olefins in contact with a fluid bed of shape selective zeolite catalyst to produce a gasoline product stream reduced in benzene content wherein the high octane value alkylaromatics formed by benzene alkylation are of low carbon number, essentially C10-. Concurrently, a portion of olefins in the gasoline stream are converted to gasoline boiling range hydrocarbons and the sulfur content of the gasoline feedstream is lowered. Besides enhancing the octane value of the feedstream, the process results in a lower Reid vapor pressure and lower sulfur content.

Abstract: In a transmitter-receiver having a transmitting circuit and a receiving circuit, it is an object of the present invention to mitigate an interference between the transmitting circuit and the receiving circuit.  A quartz-crystal oscillator is provided as a common reference signal source for the local oscillators and the relation among frequencies is determined so that the frequencies such as local oscillating frequencies and intermediate frequencies within the transmitter-receiver do not overlap each other.          Interferences between the transmitting circuit and the receiving circuit are mitigated to prevent a characteristic deterioration, spurious radiation, etc.  Thereby the transmitter-receiver may be reduced in size and weight.          Further, by sharing a quartz-crystal oscillator having a high frequency stability, narrowing of bands in radio channel spacing may be readily achieved.
