Title: Disposable cartridges for centrifugal separators
Inventor: PURVEY RONALD J
IPC: B04B7/08
Filed: 1986-02-12
Granted: 1992-01-21
Abstract: ABSTRACT             DISPOSABLE CARTRIDGES FOR CENTRIFUGAL SEPARATORS     Disposable cartridges are described which are formed from thin sheet metal pressings and wherein the base member has integrally-formed nozzles to produce less turbulent flow in the oil jets issuing from the nozzles than in known cartridges.  Less turbulent oil flow allows greater oil flow rate for a given nozzle diameter than in known constructions where oil flow is more turbulent.  The decreased turbulence promotes greater rotational velocity at a given oil pressure and enhances the efficiency of separation of contaminants from the oil.  Disposable centrifugal separator cartridges are described compris-ing a cover member, an inner flow-directing and debris-retaining member, a base member, two bearings, one each associated with the cover member and the base member and wherein the base member is a sheet metal pressing having at least two nozzles formed integrally therein and through which oil leaves the cartridge in a direction so as to produce a reaction force to spin the cartridge, the nozzles being provided in recesses in the base member, the recesses being in the form of smoothly-contoured circumferential troughs of deepening section starting with minimum depth at the beginning of the trough remote from the nozzle and finishing with maximum depth near to the plane in which the nozzle lies.

Title: Hold-down mechanism for a dock leveller
Inventor: PEDERSEN ARNE I
IPC: E01D1/00
Filed: 1986-07-10
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE     A mechanical dock leveller having a ramp pivotally connected to a support frame which is raised upwardly by a spring biased device includes a hold-down mechanism for holding the ramp at any desired raised position.          The hold-down mechanism includes a frictional brake which seizes the hold-down for the ramp at its desired elevation.  The frictional brake yields when additional upward force is exerted on the ramp, such as caused by truck springs during unloading of the truck.  This arrangement avoids damage to the ramp construction and is accomplished by a durable friction braking system which provides for a controlled infinite raising of the ramp due to truck bed elevation.

Granted: 1992-03-31
Abstract: ADJUSTABLE GEAR SUPPORT BRACKET   ABSTRACT OF THE INVENTION The tooth depth of a gear meshing with a worm wheel, such as used in an electricity meter register, is adjusted by providing a mounting plate for holding the shaft of the toothed gear having a limited range of motion for adjusting the distance of the gear from the worm.  The toothed gear has one end of its shaft attached to a mounting plate having a J-shaped cutout provided along one edge. The shaft of the gear is mounted to the "hook" portion of the cutout.  Movement of the J-shaped cutout in a direction within the plane of the mounting plate causes a corresponding change in the distance of the toothed gear from the worm, thus enabling the mesh depth between the gear and the worm to be easily adjusted. The arrangement has no moving parts and can be formed using a simple die-stamping process.

Title: Electronically programmable universal brushless dc fan with integral tracking and locked rotor protection
Inventor: BROWN FRED A
IPC: H02H7/085
Filed: 1987-01-19
Granted: 1991-03-19
Abstract: ABSTRACT        A brushless DC fan (10) with a winding supply circuit (49) having an internal voltage regulator (53) can afford current limiting and thermal protection and provide various desired fan speeds without alteration of the basic fan circuit, the windings, or other manufacturing items.  A voltage setting circuit element (63) can set fan speed externally and can be used to establish various fan speeds.  An internal voltage establishing circuit element (58) sets the maximum speed.  The regulator replaces the fan's protective thermistor to shut down the voltage to the windings (47) when locked rotor occurs.  Bringing out a lead (21) for the purpose of connecting a speed controlling resistor, thermistor, or active programming means to the internal circuitry enables the fan's end user to alter operation as needed.

Filed: 1987-06-10
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE      A web transfer apparatus is disclosed for transferring a web from a press section to a dryer section.  The transfer apparatus includes a dryer fabric extending around the dryer section for conveying the web from the press section to, and around, the dryer section so that excess water remaining in the web after the press section is removed from the web when passing through the dryer section.  A first plurality of ro-tatable rolls movably support the dryer fabric and a frame rotatably supports the first plurality of rolls.  The first plurality of rolls includes a lead-in roll which is disposed adjacent to the press section for guiding the web from the press section towards the dryer section.  The first plurality of rolls also includes a first transfer roll which is spaced relative to the lead-in roll for guiding the web through the dryer section.  A transfer fabric cooperates with the dryer fabric such that the transfer fabric and dryer fabric define therebetween a transfer section which extends along the dryer fabric and between the lead-in roll and the transfer roll.  The transfer section permits support of the web therethrough so that the web is easily led to the dryer section while inhibiting any tendency of the web to droop during threading of the web from the press section to the dryer section.

Title: Gallium arsenide logic design system
Inventor: CRAY SEYMOUR R
IPC: H01L21/8232
Filed: 1988-09-12
Granted: 1991-12-03
Abstract: A GALLIUM ARSENIDE LOGIC      DESIGN SYSTEM     ABSTRACT OF THE DISCLOSURE         A gallium arsenide logic design system is described for designing custom or semi-custom LSI integrated circuits using standard cells from a cell library.  D-MESFET transistors and Schottky diodes are used for implementing the cell types in gallium arsenide to produce performance levels of less than 150 pico-seconds per gate propagation delay.  Each integrated circuit die is built from a cell library containing three standard cells.  The limitation on the number of standard cells used for logic design allows for fast and efficient turnaround time between logic design and fabrication.  A minimum number of masks are required for implementing the custom integrated circuit due to the efficient design of the cell types.  The placement and interconnect of the cells on the die are also performed in an efficient manner due to the predefined allowable locations for cell placement and the predefined allowable route channels for the interconnect.          A clock amplifier cell is also described for the cell library which differentially phase corrects a two-phase clock signal to ensure that the two clock lines are perfectly out of phase at all times.  The com-bination of this strictly controlled two-phase clock with the gallium arsenide cell designs allows digital logic implementations at an LSI level to operate at 1-GHz clock frequencies.

Abstract: ABSTRACT            The device is provided for measuring an exact amount of fluid in a dispensing operation, the device being made easily portable and self-contained.  The fluid motor has a device on it to measure the number of rotations of the motor and that number of rotations is translated through appro-priate circuitry into a corresponding fluid volume.  Initia-tion of the dispense cycle by means of manually opening a handle latches open a valve which stays open until the desired predetermined volume of fluid has been dispensed.          At that point, a solenoid is energized with a brief electri-cal pulse which unlatches the valve and allows it to close quickly, thereby assuring that an extremely accurate amount of fluid has been dispensed.
