Title: Thick-film non-step resistor with accurate resistance characteristic
Inventor: GASTON ROBERT D
IPC: H01C10/32
Filed: 1991-03-27
Abstract: A smooth resistance characteristic, a reduction in component cost, and high durability are achieved for a variable resistor card formed using thick-film silk screen deposition. An arcuate wiper track and radial extension areas are all formed of a resistance material deposited using silk screen techniques. Laser trimming of the extension areas provides a desired characteristic of resistance versus sweep angle for the variable resistor. The resistance characteristic is continuous and nonstepped, thereby avoiding the creation of spikes caused by small circuit breaks during sweeping movement of the wiper contact.

Filed: 1991-09-24
Abstract: PATENT Dkt. 88A289 ABSTRACT OF THE DISCLOSURE   Described is an improved pressure-swing adsorption process and apparatus which enable more thorough regeneration and, thus, a higher yield of one or more selected gases and a higher productivity of the adsorbent material.  The pressure-swing adsorption process and apparatus for obtaining a selected gas are of the type wherein a PSA product gas is obtained by the steps of pressurizing, producing, purging and venting a vessel that contains an adsorbent for a gas other than the selected gas.  The improvement is a step of purging the adsorbent with a purge gas that has a higher concentration of the selected gas than the PSA product gas.

Patent CA-2058928-A1 (CA)
Inventor: WONG JACOB Y
IPC: G08B17/103
Filed: 1991-03-29
Abstract: A fire detector that responds more rapidly than the widely used somke detectors senses increases in the concentration of carbon dioxide associated with a fire. The build-up of carbon dioxide is sensed by measuring the concomittant increase in the ab-sorption of a beam of radiation whose wavelength is located at a strong absorption band of carbon dioxide. The device is consid-erably simplified by the use of a window (48) to the sample chamber (44) that is highly permeable to carbon dioxide but which keeps out particles of dust, smoke, oil, and water. This permits the fire detector to be built of very inexpensive materials.

Abstract: Disclosed is a plasma torch in which the position of the center electrode (1) 13 adjustable relative to the orifice of the plasma torch (2). The invention is based on a construction in which the center electrode (1) is mounted to the body part (9) of the plasma torch by way of a pivotal ball joint (7, 23), whereby the electrode (1) can be pivotally rotated in said joint (7, 23), thus making it possible to align the electrode tip to the orifice center of the plasma nozzle (2). The spherical element (7) of the pivotal joint is attached to the bearing box (23) with the help of a tightening gland nut (11, 12). The depth of the center electrode (1) can be adjusted by rotating a depth adjustment gland nut (14), which is attached to the spherical element (7) by a threaded joint. Due to its versatile adjustability, the function of the plasma torch can be maintained in a stable range, thus significantly contributing to reduced wear and damage of the plasma nozzles.

Abstract: In a motor with permanent magnets and a motor system, the value .alpha. produced by dividing, by the induced voltage constant ke, the product of the inductance Lm of the motor itself or the inductance Ls of the motor system in the d-q coordinate system is selected to meet a predetermined condition. The range of rotational speeds in which the motor can be operated while maintaining a predetermined output under field weakening control can be widened. If a condition is established to determine a ratio by which the rated rotational speed under normal operating conditions is multiplied into a rotational speed under field weakening control, then conditions for a motor or a motor system that can be used can be determined.

Title: Epoxy resin curatives and method
Inventor: SU WEI-YANG
IPC: C08G59/40
Filed: 1992-04-08
Abstract: ABSTRACT OF THE DISCLOSURE      (D#81,039-F) An epoxy resin composition comprises the cured reaction product of an epoxy resin and a lactone-imidazole complex.  For example, complexes of butyrolactone and caprolactone with 1-isopropyl-2-methyl imidazole were formed wherein the mole ratio of lactone:imidazole ranged from 1:1 to 2:1.  The complexes are less reactive than the imidazole alone, giving them an extended pot life.  The compositions are useful for making filament windings where an extended working time is required.  Other applications include those in which it would be impractical to use the more reactive unmodified imidazole as the sole curing agent.     81039.APP2

A counterpressure equal to at least the mold-ing pressure being generated as each successive packed bri-quette is joined at the molded end of the continuous molded blank. Then products of required length  are cut from the resultant continuous shaped blank. An apparatus for carry-ing out a method comprises the chamber (4) for molding the briquettes which comprises two multi-faceted truncated pyramids (15, 16) joined together along the perimeter of their minor bases, the side facets of which are rigidly secured to the frame so that the geometric axes of the py-ramids (15, 16) coincide with the molding axis (X-X) of the continuous blank.
