Title: Unitary enclosure and cover therefor
Inventor: OTTO DENNIS L
IPC: F16J15/32
Filed: 1990-11-13
Abstract: ABSTRACT The interior of an antifriction bearing is isolated with an enclosure having a case which fits into the outer race of the bearing and primary and secondary lips which establish a barrier along a sealing surface that is located beyond the inner race of the bearing.  The primary lip, which is presented toward the interior of the bearing, does not actually contact the sealing surface, but does have pumping cavities which direct lubricant, that migrates along the sealing surface, back toward the interior of the bearing.  The secondary lip projects away from the primary lip and actually contacts the sealing surface.  The case, primary lip and sealing lip are all molded from a common polymer as an integral unit.  Where the journal around which the bearing fits ends beyond one end of the bearing, a polymer cover may be snapped over the enclosure at that end of the bearing to provide an extra measure of isolation.

Filed: 1991-01-07
Abstract: A material grinding mill of reversible character having hog-type hammers formed with chisel edges pivotally mounted on supporting discs, and further formed with landing areas positioned to contact the supporting discs so that the chisel edges are prevented from impacting upon or nicking the discs. The pivoting of the hammers allows them to rebound when encountering a body of hardened material so the hammer reverses direction, hence the landing area impacts on the discs and the discs are protected against being nicked by the chisel edges of the hammers.

Abstract: An air dam attaches to the underside of a motor vehicle and extends downwardly therefrom into proximity with the road surface and potential interference with curbs or like obstructions extending above the road surface.  The air dam is comprised of a generally rectangular flexible sheet with an upper edge and a lower edge defining an air deflecting surface therebetween.  A bracket attaches the upper edge of the flexible sheet to the underside of the motor vehicle with the air deflecting surface cantilevered generally horizontally forward from the bracket so that the lower edge is spaced substantially above the road surface. The air deflecting surface is disposed in the oncoming airstream so that the flexible sheet is flexed downwardly progressively in response to the force of air pressure impinging on the air deflecting surface whereby the lower edge remains poised substantially above the road surface to clear obstructions extending above the road surface when the vehicle is traveling at low speeds and extends downwardly into substantial air defecting proximity with the road surface at high vehicle speed.

Patent CA-2041320-A1 (CA)
Inventor: LINDNER HARALD
IPC: B61G5/06
Filed: 1991-04-26
Abstract: The reliable initiation and chronological sequence for coupling or uncoupling a mechanical middle buffer coupling and an electrical cable coupling arranged on the buffer coupling longitudinally displaceable in the direction of the coupling axis with a common rotary drive is effected with minimum control effort.  A coupling device has a drivable shaft at right angles to the coupling axis.  An actuating arm is nonrotatably fastened to the drivable shaft, and extends into a guide rail of the cable coupling and thus forms the direct drive member of the cable coupling.  The shaft is guided rotatably and is longitudinally displaceable in a lower section of a hollow shaft, which consists of a lower, a middle, and an upper hollow shaft section.  The shaft extends beyond the middle hollow shaft section in the upward direction into the zone of the upper hollow shaft section where the shaft is guided longitudinally displaceably but nonrotatably.

Title: Controlled initial target-dependent production of templates for ligase chain reaction
Inventor: BACKMAN KEITH C
IPC: C12Q1/68
Filed: 1991-08-26
Abstract: Abstract of the Disclosure An improvement to the ligase chain reaction (LCR) method of selectively and geometrically ligating nucleic acid probes; before the LCR, a template-dependent controlled reaction increases the population of templates capable of supporting template-dependent ligation in LCR selectively in the presence of target nucleic acid, while substantially avoiding creation of any molecules capable of supporting template-dependent ligation in the absence of target nucleic acid.  One way to control the initial reaction is to weight the reaction to create templates corresponding to only one of the two target strands, using e.g. template dependent ligation or polymerization.  Another way to control the initial amplification is to create templates corresponding to both strands, but to prevent spurious creation of ligation templates by using a probe concentration low enough to avoid blunt end ligation or by using a method of amplification such as PCR that does not generate spurious ligation templates.

Abstract: An apparatus and method are disclosed for processing glass-making  materials  under  oxidizing  conditions,  and  for  processing materials, such as hazardous or toxic wastes, or smelting under re-ducing conditions.  As a glass-making apparatus the invention includes a cyclone melt reactor for forming a liquid glass melt and a combus-tion preheater for receiving the glass-making materials and combusting the fuel and oxidant therein to heat the glass batch materials to a temperature at least equal to the melt temperature of the glass batch material.   The combustion preheater has an outlet connected to the glass melt reactor, and at least one inlet is provided into the com-bustion preheater for introducing oxidizing materials and for creating a well-stirred region within the combustion preheater means.  Supple-mental heat can be provided by introducing a heated transfer gas into the combustion preheater, and a fuel gasifier can be provided for pro-ducing a fuel gas before the fuel gas is injected into the combustion preheater.   For processing materials under reducing conditions,  the cyclone melt reactor is connected to a preheater/reducing chamber and preheated reducing gas is introduced into the reducing chamber in such a manner that a well-stirred region is created within the reducing chamber.  Heated transfer gas from a supplemental heat source and re-ducing gas from a fuel gasifier can also be introduced into the re-ducing chamber.

Abstract: BALER FOR FORMING CYLINDRICAL BALES          ABSTRACT OF THE DISCLOSURE             A baler of the type for forming cylindrical bales is improved by  the  use  of a  combine  type pickup which more effectively lifts the crop from the ground for insertion into the  main  baler  housing.    Between  a  feeder  housing  of  the combine type pickup and the main baler housing is provided a transportation section under which is provided a belt to ensure that  any material falling from the transportation section is caught by the belt and carried rearwardly for collection in an auger and fan assembly.   The auger and fan assembly provides a low pressure within the baler housing which is substantially fully enclosed so that all material is kept within the baler and prevented from escaping.  The collected material in the fan is carried through a duct to a discharge cyclone dropping the material back into the transportation section for carrying into the  baler  housing  for  baling.    The  frame  of  the baler  is mounted  upon  steerable  wheels which  allow the pickup  to be arranged at an angle to the swath and allow the pickup to be steered across the swath to ensure that it properly follows the swath while the tractor continues in a straight line.
