Title: Machine de conversion d'energie avec pistons tournant en paires l'un parrapport a l'autre, a l'interieur d'un carter spherique
Inventor: LARSEN THOR
IPC: F03C4/00
Filed: 1990-01-04
Abstract: Appareil de conversion de l'énergie qui comprend un rotor muni d'un premier élément de rotor (124) et d'une première paire de pistons (137 et 138) ainsi que d'un deuxième élément de rotor (125) et d'une deuxième paire de pistons (135 et 136). La deuxième paire de pistons peut, à l'intérieur du logement (10 et 110) de l'appareil, se déplacer par basculement dans un mouvement de va et vient par rapport au premier élément. Ce premier élément est relié à l'arbre de rotation (117) de l'appareil. Quant au deuxième élément (125), il est relié par un moyen non rotatif au premier élément du rotor (124), mais il peut se déplacer par basculement par rapport à ce dernier. Par conséquent, le premier et le deuxième élément du rotor sont ensemble articulés par rapport à l'axe de rotation. Le premier élément suit un premier trajet de révolution, tandis que le deuxième élément suit un deuxième trajet de révolution qui est différent de celui du premier élément. Les deux éléments (124 et 125) se trouvent à l'intérieur d'une génératrice sphérique commune. Un dispositif de guidage (116), qui permet d'assurer à ce que le deuxième élément du rotor (125) suit le deuxième trajet de révolution, est placé au centre du rotor (124 et 125) et est relié de façon rigide au logement de l'appareil.

Title: Continuous process for preparing poly(butylene terephthalate) oligomer or poly(butylene isophthalate) oligomer
Inventor: JACKSON ROY
IPC: C08G63/78
Filed: 1991-07-26
Abstract: Economic and efficient process for preparing an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) Pram a transesterification reaction mass by using a countercurrent column reactor system wherein the transesterification reaction mass is fed into the countercurrent column reactor and continuously flows downward while simultaneously a heated inert gas stream continuously flows upward to scrub out volatiles from the transesterification reaction mass, thereby yielding from the bottom of the countercurrent column reactor an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) suitable for use in a polycondensation reaction. Butanediol is recycled throughout the process through an absorber column.

Title: Gas reacting apparatus and method
Inventor: SPINK DONALD R
IPC: B01D53/18
Filed: 1991-10-16
Abstract: Gas reacting apparatus and method are described for wet mass transfer of solute gases from a gas stream with a  liquid  or  slurry  reacting  medium capable  of chemisorption of solute gases in the gas stream.   The apparatus  comprises  an  elongated  conduit  means  and plurality of dual-fluid spray means coaxially spaced in series within the conduit means and countercurrently or cocurrently directed to the gas stream for spraying the liquid or slurry reacting medium into the conduit means to form a plurality of spray contact zones of uniformly-distributed fine droplets, which may be in individual gas-liquid contact zones,  wherein intimate contact of high interfacial surface area between the sprayed liquid or slurry and the gas stream is effected to remove solute gases from the gas stream.  Such individual gas-liquid contact zones may be separated by demisters which agglomerate  and remove  liquid droplets  from the gas stream  before  it  passes  to  the  next  zone,  with  a demister also being provided at the outlet.

Patent CA-2062629-A1 (CA)
Title: Apparatus and method for liquid sample introduction
Inventor: FRENCH JOHN B
IPC: G01N30/72
Filed: 1992-03-10
Abstract: A liquid sample to be analyzed is fed to an ink jet printer micro pump.  The pump directs the solution, as a stream of uniformly sized and spaced droplets, into a laminarly flowing stream of hot carrier gas.  The carrier gas evaporates the solvents (e.g. water) in the droplets to form a stream of dried particles.  The particles are vaporized by a plasma, laser or other heat source.  The vapour can be ionized and the ions analyzed by a mass spectrometer, or the vapour can be analyzed by optical spectroscopy.  The method reduces oxide and other interference effects, increases sample utilization, and reduces waste,  signal  noise,  and  memory  effects,  increasing instrument productivity.  Multiple nozzles can be used to change samples or to shoot calibrating droplets, further increasing productivity.   Signal detection can be synchronized with droplet firing, or the signal, which is intrinsically modulated at the drop frequency, can be low pass filtered and synchronously detected, to increase the signal to noise ratio.  The dried particles can also be directed into a vacuum chamber and deposited in a desired pattern on  a surface  in the vacuum,  thus  delivering controlled micro-dosages of material onto the surface.

Patent CA-2065122-A1 (CA)
Inventor: YOUNG STUART D
IPC: A01K1/015
Filed: 1992-04-03
Abstract: A plurality of rectangular, hexagonal concrete slabs are employed and adjacentlydisposed to form a flooring for a hog pen having elevated sides or margins. Each slat has a plurality of apertures so that the porosity of the slat, in closer proximity to the walls of the pen, is greater than through the central region of the pen. This provides, because of the observed behavior of the hog, a greater porous region adjacent the walls of the pen where the animal tends to defecate, the defecation running through the slots into a collection region below the elevation of the slats. The central region which has a less porosity, is more suitable for the animal to walk or lay upon. When the animal walks near the sides of the pen, the hoof action of the hog on the slat tends to push any feces collected on the top of the slat through the apertures into a collection region below the elevation of the slats and hence, the pen is maintained clear of defecation by the actual movement of the hogs. Pen cleaning by the farmer is reduced or avoided.

Abstract: ACCELERATION ACTIVATED ENERGIZING DEVICE     ABSTRACT OF THE DISCLOSURE A lighted nock is provided for an arrow which undergoes an initial acceleration when shot from a bow and thereupon reaches a zero acceleration during night shortly in front of the bow. The nock is formed of transparent material within which is embedded a light emitting diode. An elongate cavity is positioned within the forward portion of the nock and within that cavity there is slideably located an elongate battery having a rod-shaped forward electrode and a rear face forming a second electrode. An energy storing spring is positioned within the cavity and a second cavity is positioned adjacent the first cavity. Within the second cavity there is located an electrical contact and between the two cavities is a position delimiter formed as an annular silicone ring. As the arrow is shot, the energy storage spring moves into compressive contact with the rearward face of the battery and is compressed to store energy sufficient, upon the arrow reaching zero acceleration, to cause the battery forward rod-shaped end to penetrate the position delimiter and close a circuit. Electrical contact between the second terminal of the diode and the battery is provided by an elongate spring of low spring rate positioned coaxially within the energy storage spring and maintaining continuous abutting contact with the rearward face or terminal of the battery.
