Title: Four-point support system for appliances, particularly refrigerators
Inventor: JENKINS THOMAS E
IPC: F25D23/00
Filed: 1988-01-14
Granted: 1995-06-20
Abstract: A refrigerator cabinet has a front roller at each front corner and a pair of rear rollers disposed closer to each other than the pair of front rollers.  The centers of the rear rollers are closer to each other than the sum of the distances of the center of each rear roller from an adjacent side wall of the cabinet.  The front rollers, which are disposed rearwardly of the front wall, are adjustable vertically while the rear rollers are not.  This arrangement decreases the deflection of a refrigerator cabinet when it is positioned on an uneven floor.

Granted: 1995-10-10
Abstract: A disposable test pack for monitoring the efficacy of steam or ethylene oxide sterilization cycles includes a fiber board housing for a biological indicator.  The housing includes an outer tube and a shorter inner tube.  The outer tube has upper and lower portions which define a seam or gap at their adjoining open ends.  The inner tube extends past the seam and telescopes into the upper and lower portions.  The seam and the close tolerance between the inner tube and the upper and lower portions of the outer tube provide a tortuous path for the entry of sterilant into the interior of the housing.  The tortuous path has a moisture absorbent surface and is dimensioned to promote intimate contact between the sterilant and the absorbent surface.  The exterior of the housing can be lined with foil to prevent sterilant from permeating the housing, thereby preventing entry of the steam by any path other than through the seam.  A hole covered by an optionally removable tab is provided at the end of the upper portion of the outer tube for use in monitoring ethylene oxide sterilization cycles.

Granted: 1993-04-06
Abstract: VALVE AND NOZZLE SYSTEM FOR INK JET PRINTING APPARATUS   Abstract of the Invention:        A valve and nozzle system for drop on demand ink jet printing apparatus wherein a single valve communicates with a plurality of orifices for controlling the flow of ink simultaneously through the orifices.  The valve has a chamber with an inlet port and a plurality of outlet ports communicating with the chamber.  The outlet ports have seats that are in a common plane and a piston has a face that, when the valve is closed, simultaneously seats against all the outlet port seats to close the valve.          When a solenoid is energized to withdraw the piston and open the valve, the valve face separates simultaneously from the outlet port seats.  Thus the outlet ports are opened and closed simultaneously.

Title: Rare gas-halogen excimer laser
Inventor: LEVATTER JEFFREY I
IPC: H01S3/225
Filed: 1988-08-30
Granted: 1992-12-15
Abstract: ABSTRACT OF THE INVENTION        A rare gas-halogen excimer laser in which the laser  gases  are  exposed  virtually  only to metal  and ceramic, thereby reducing contamination of the gases and optics.   In  one  preferred  embodiment,  magnetic  fluid seals are used to isolate the bearings supporting the shaft upon which the tangential fan rotates so that the lubricated bearings do not contaminate the laser gases. The  fan  uses  magnetic  coupling  so that  an  isolating enclosure may be placed over the seal to prevent the leakage of gases into the environment should the seal fail.    An  excimer laser that  is therefore both  safe enough to be used in medical and industrial applications as well as reliable may be fabricated.

Title: Gas burner
Inventor: JANNEMANN THEO
IPC: F23D14/02
Filed: 1988-09-26
Granted: 1992-06-23
Abstract: ABSTRACT            The gas burner comprises a mixer, a conical transition member adjacent thereto on which a cylindrical burner shell with openings and whose top is closed by a burner lid is mounted.  Clamped between the burner lid and the transition member is a throttling cylinder which is filled by the super-stoichiometric gas mixture at super-atmospheric pressure.   In order to avoid burner pulsations the cylinder has throttling openings whose total area is 2 to 10%  of  the total area  of the openings. The throttling openings are in a plurality of circular rows above one another in such a manner that they are on a respective vertical line.  Vertical, imperforate sections of the burner shell are opposed to the lines so that the mixture jets from the throttling openings do not impinge directly on the openings.  The cylinder is provided at a coaxial spacing of 5mm from the burner shell.

Abstract: ABSTRACT          PROCESS FOR PREPARING AN EMULSION EXPLOSIVE HAVING ENTRAINED                        GAS BUBBLES A process for preparing a gas bubble sensitized explosive composition.  The present process comprises preparing an explosive composition comprising a water-in-oil emulsion and mechanically entraining gas bubbles into the explosive composition.  Low viscosity emulsion explosives are able to be sensitized by this process.  There is a preference for wax free emulsions to be used.  The process is applicable to emulsion explosives comprising ammonium nitrate particles.  By providing a process for the mechanical entrainment of stable gas bubbles we allow explosive compositions to be sensitized on-site by readily available mixing means.

Abstract: Method and apparatus is disclosed which inexpensively and conveniently tests ordinary twisted-pair (TP) telephone wires installed in a premises for suitability interconnecting elements of a high-speed local area network (LAN).  The method eliminates the need to trace the wires or to disturb them in any way.  Signals are transmitted onto the near end of the TP wires and are reflected from their open far ends.  The received reflected signal,from a selected TP wire is compared against the transmitted signal and the TP wire is deemed satisfactory if the comparison shows a bit error rate (BER) less than a predetermined upper limit.  Preferably the method is used in conjunction with a directional coupler connected to a transceiver which conducts the signal generated by the transceiver onto the TP wires and conducts the reflected signal from the selected TP wire to a receiver portion of the transceiver.

Abstract: LOWERED TAILGATE AND AIRFLOW DIRECTING WING            FOR PICKUP TRUCK                           ABSTRACT A tailgate for a pickup truck includes three elongate, rectangular panels or louvers having an airfoil-shaped cross section pivotally mounted in a U-shaped tailgate frame conformed to be mounted on a pickup truck in place of the conventional tailgate.  The louvers are linked to each other for coordinated pivotal movement about respective horizontal axes extending along the leading edge of the airfoil section between a closed position and an open position wherein the louvers project rearwardly from the frame to accommodate a substantially unrestricted flow of air through the tailgate.  A reversible electric motor controlled from the cab drives the louvers in pivotal movement through a worm gear drive which will hold the louvers at any selected position.  An airfoil section wing is mounted at the rearward end of the truck cab in spaced relationship to the cab roof and sidewalls to reduce turbulence in air flowing toward the tailgate.
