Filed: 1991-11-12
Abstract: A hose coupling wherein a tubular connector has a first portion with an internal annular wall and an internal annular protuberance, and a cylindrical second portion.  The protuberance is located between the wall and the second portion, and the first portion has axially extending elastic arms with pallets which can engage an external rib of a pipe when the terminal portion of such pipe is introduced into the first portion.  A thin-walled metallic sleeve has a larger-diameter first section with a free end which is receivable in an annular socket of the wall after having passed within and beyond the protuberance upon entering through the open end of the second portion of the connector.  At such time, the first section deforms and/or is deformed by the protuberance.  The terminal portion of a hose is thereupon introduced between a smaller-diameter second section of the sleeve and the second portion of the connector before the second section is deformed from within to clamp the hose against the internal surface of the second portion of the connector.  A sealing ring is confined and deformed between the internal surface of the first section of the sleeve and the peripheral surface of terminal portion of the pipe when such terminal portion is inserted into the connector.

Title: Refrigeration pull down technique
Inventor: TRUCKENBROD GREG
IPC: F25D11/00
Filed: 1992-01-14
Abstract: REFRIGERATION PULL DOWN TECHNIQUE               ABSTRACT OF THE DISCLOSURE    Apparatus for and method of rapidly bringing a controlled  space  to  a  desired  temperature.    The technique is particularly applicable to the maintenance of controlled temperature spaces for the transportation of perishable cargo, such as in refrigeration trucks.          Immediately  following  completion  of  the  loading process,  it  is  desirable  to  bring  the  internal temperature  of  the  controlled  space  to  the  proper operating  point  as  quickly  as  possible  to  retard spoilage.     However,   it  is  necessary  to  avoid unacceptable overshoot to prevent damage to the cargo by freezing.   The disclosed system employs multiple sensors and a control algorithm to permit pull down to occur  as  rapidly  as  possible  without  unacceptable overshoot.
Patent CA-2060754-A1 (CA)
Title: Oldham compressor
Inventor: RICHARDSON HUBERT JR
IPC: F04B53/12
Filed: 1992-02-06
Abstract: ABSTRACT The present invention is a compressor using an Oldham-type assembly functioning as a piston to provide a compressing pump.  An orbiting plate is eccentrically mounted on the crankshaft, and a compressing pump body is fixed within the interior of the housing.  An Oldham piston is disposed within the compressing pump and has tabs which engage slots on the orbiting plate.  The side walls of the pump body prevent movement of the Oldham piston in a first direction so that the orbiting of the plate causes the piston to reciprocate in a second, orthogonal direction. Suction valves on the piston control entry of refrigerant into the compressing pump, and discharge valves control refrigerant discharge.

Title: A method of stabilizing recombinant hepatitis b virus surface proteins from recombinant host cells
Inventor: SITRIN ROBERT D
IPC: C12N15/09
Filed: 1992-03-06
Abstract: TITLE OF THE INVENTION A METHOD OF STABILIZING RECOMBINANT HEPATITIS B VIRUS SURFACE PROTEINS FROM RECOMBINANT HOST CELLS          ABSTRACT OF THE DISCLOSURE         Recombinant hepatitis B virus surface proteins produced in recombinant host cells are rapidly and efficiently purified from heated whole cells at neutral pH.  The whole cells are heat treated, cooled and in the case of high pH extract, the pH is reduced.  The surface proteins are then adsorbed onto wide pore silica followed by elution and concentration.  This method eliminates the requisite introduction of protease inhibitors, stabilizes the surface protein and improves product yield.

Title: Probe to specifically determine the injectivity of a petroleum well and measuring method implementing said probe
Inventor: NICOLETIS SERGE
IPC: E21B47/06
Filed: 1992-03-19
Abstract: Probe to specifically determine the injectivity of a petroleum well and measuring method implementating said probe ABSTRACT OF THE DISCLOSURE     During  conventional  injection  tests conducted  on petroleum  operating wells,  these operations  have been effected  up   until  now  by  measuring  the  hydraulic characteristic  quantities  of the  fluid injected  into the  well (mainly pressure, temperature,  flowrate). The present  invention  adds  to  microseismic  measurements representative  of  the  acoustic  emission  induced  by injection.    The  present  invention thus makes use  of a  probe constituted by  a bucket chain mainly containing tubular cartridges  interconnected  by flexible  cables with  at least  some of said cartridges  housing means to measure the   microseismic  quantities  representative   of  the acoustic  emission induced by  the injection of  a fluid into  the well,  and wherein all  the cartridges  have a sufficiently  small diameter so as  to be engaged inside a pipe column disposed in the well.    Parallel  with this, the present invention makes use of  a  measurement  method using  this  probe during  an injection  test  comprising  at  least  one  period  for injecting  the  fluid, followed  by a  rest period,  the pipe  column   of  the  well  comprising  at  least  one perforation  level, wherein  the probe  is lowered  into the   well  and  then   is  immobilized  close   to  the perforation  level   so  as  to  measure  at  least  the microseismic   quantities,  preferably  associated  with hydraulic quantities, at least during the rest period.    Apart  from obtaining a more accurate picture of the injectivity  of  the well,  the  present invention  thus concerns a  test procedure much better adapted to actual requirements  (via the modularity of  the probe) and one which is much less  cumbersome (the probe  carrying out several   measurements   during   a  single   to-and-fro movement in the well).

Title: Ignition assisting device for internal combustion engines
Inventor: RICHARDSON RONALD D
IPC: F02B19/12
Filed: 1990-10-15
Abstract: A capsule (10), the interior volume of which is an ignition chamber (14), is provided with an engine to improve ignition. The capsule (10) has an orifice (36) so the ignition chamber (14) can communicate with a main combustion chamber (54) of the engine.  Often, the capsule (10) is connected to a spark plug (16) and the electrode gap (28) of the spark plug (16) is in the ignition chamber (14). The capsule (10) causes the combustible mixture in the engine to swirl in a controlled manner as it flows from the orifice (36) towards the electrode gap (28). The interior surfaces (12) of the capsule (10) are contoured such that momentum of the swirling combustible mixture is conserved, thus maintaining the velocity of the swirling combustible mixture as it proceeds from the orifice (36) of the capsule (10) to the electrode gap (28) and also providing an increased velocity of the ignited mixture as it exits the capsule (10).

Filed: 1991-03-21
Abstract: 2079099 9114457 PCTABS00007 Method for examination of internal body tissues by NMR (nuclear magnetic resonance) imaging procedures, and especially for examination of the alimentary tract, by administering an inert proton-rich organo-silicon polymer as a contrast medium within the body of the subject to be examined. The polymer is preferably a polysiloxane, especially a polydimethylsiloxane. It can be administered easily as an emulsion, and is inert, non-toxic, and not absorbed or degraded in the living body. It overcomes the disadvantages of known imaging techniques using a contrast agent or opacifying agent which relies upon introduction of a metal derivative, which can have undesirable side-effects. It can be used without the need for image enhancement techniques (e.g. with older NMR equipment) as well as with more modern equipment. The method can give consistent and high quality imaging results and used as a part of a diagnostic method in the study of soft internal body tissues and cavities, as it gives selective contrast to the gut contents (for example the colon, duodenum and other parts of the alimentary tract).
