Title: Cleanup of contaminated hydrocarbon conversion system to enable use with contaminant-sensitive catalyst
Inventor: PEER ROGER L
IPC: B01J29/74
Filed: 1990-07-30
Abstract: Performance of a process, for catalytic conversion of a substantially contaminant-free hydrocarbon feed with a contaminant-sensitive catalyst using a conversion system having equipment contaminated through contact with a contaminant-containing prior feed, is substantially improved by using a sacrificial particulate bed to remove contaminants such as sulfur from the contaminated conversion system prior to loading the contaminant-sensitive catalyst.      After contaminant removal is substantially complete, the sacrificial particulate bed is replaced with the contaminant sensitive catalyst and the contaminant-free feed is charged to the conversion system at hydrocarbon conversion conditions.

Title: Self-sealing snap-in receptacle, especially for circuit breaker cover retention
Inventor: RAINE PETER D
IPC: E05C19/06
Filed: 1990-08-24
Abstract: ABSTRACT OF THE DISCLOSURE      A receptacle is provided which snaps into and seals an opening in a circuit breaker case.  A pair of opposed, resilient tabs hold the receptacle within the opening, and substantially prevent withdrawal of the receptacle from the opening.  A pair of resilient legs form a flexible U-shaped notch which is adapted to receive and hold a male member attached to a circuit breaker access cover.  Therefore screws are not needed for securing the circuit breaker access cover to the circuit breaker case, and the cover is easily removed and replaced any number of times without the use of special tools.

Title: Method of and apparatus for removing non-metallic inclusions from molten metal
Inventor: MIKI YUJI
IPC: B22D41/01
Filed: 1990-09-19
Abstract: A method of removing non-metallic inclusions from a molten metal comprises the step of simultaneously applying both a horizontal rotation of the molten metal and heating of the molten metal by induction heating.  After the simultaneous application of rotational force and heat, the induction heating may be stopped while the horizontal flow of the molten metal is maintained, so as to promote the separation of the particles of the inclusions.  The method is carried out by using an apparatus which has a vessel which contains the molten metal, a rotary magnetic field generating device surrounding the vessel, and an induction heating device also surrounding the vessel.  Each of the rotary magnetic field generating device and the induction heating device may be divided into a plurality of circumferential segments and arranged such that the segments of both devices are alternately disposed around the vessel.

Title: Method for making glass fiber mats using controllable fiber glass strand feeders
Inventor: BAILEY PAUL E
IPC: D01G25/00
Filed: 1990-10-02
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to improvements in making mats of continuous fiber strand using controlled reciprocating strand feeders.  More particularly, the invention relates to improvements in making continuous fiber glass strand mats having more uniform density by electronically controlling both the rate of reciprocation and the rate at which strands are deposited onto the surface of a moving conveyor while also reducing the vibration associated with the feeders.  Still more particularly, the invention relates to improvements in the production of two continuous fiber glass strand mats, one having uniform mechanical properties while the other possesses directionally dependent ones. In the preferred embodiment, brushless stepper or indexing motors are used to reverse the direction of reciprocating strand feeders quickly and smoothly so as to minimize their vibration.  Also provided are variable speed electric motors in conjunction with a programmable logic controller and frequency inverter to adjust the rate at which strand is deposited by the feeders onto the moving conveyor. It is shown, by way of example, that these improvements result in increased uniformity of both mat density and thickness.

Title: Recirculating gas separator for electric submersible pumps
Inventor: POWERS MASTON L
IPC: B01D19/00
Filed: 1990-10-12
Abstract: Abstract Of The Disclosure A recirculating gas  separator  for  a  submersible well pump includes a rotary gas separator for separating liquid to be directed to the pump from a gas.   The separator in-cludes a separating chamber, a well fluid inlet upstream of the  separating  chamber,  and  a  liquid discharge  outlet downstream  of  the  separating  chamber.    A  recirculating system recirculates a portion of the liquid discharged from the discharge outlet back to the separating chamber so that a  gas-to-liquid  ratio  in  the  separator  is  substantially lower than a gas-to liquid ratio of well fluid entering the well fluid inlet.  Thus, the submersible well pump with the recirculating  gas  separator  can  successfully  pump  wells having substantially higher gas-to-liquid ratios than can be accomplished with prior devices.

Inventor: BERGAN TERRY
IPC: G01L1/22
Filed: 1990-10-26
Abstract: A novel load cell which is specially adapted for use in novel wheel load scales and novel weigh-in-motion scales is provided herein. The load cell comprises a metal rod or bar, with a strain transducer which is secured to a flattened portion of each of the upper and lower faces of the metal bar. A signal wire has its terminal secured to an end face of each of such strain transducer, and a strain relief element is interposed between each such signal wire terminal and its associated strain transducer. When mounted within a closed bore which is parallel to the upper surface of a flat plate of elastic material, e.g., sheet metal, in a particularly-recited manner, an improved wheel load scale or weigh-in-motion scale is provided. This provides a light weight, low profile, scale which is isolated from external interference, which thereby improves the accuracy of the scale.
