Patent CA-2066448-A1 (CA)
Title: Packaging for perishable goods
Inventor: GARWOOD ANTHONY JAMES MURRAY
IPC: B65D81/20
Filed: 1990-08-29
Abstract: Packaging is disclosed which comprises a plastics material base (1), goods (5) such as red meats within the packaging, a clear plastics material lid (3) over the base (1) sealing the packaging. A  gas is provided within the packaging for enhancing the keeping properties of the goods (5). Typically the gas is 80 % O2 and 20 % CO2 for red meats and the volume of the gas approximately equals the volume of the meat so that the meat will have a packaged shelf life of at least several days without discolouring. The goods (5) are held to the base (1) by strand means (7) so the goods do not flop around within the packaging. The strand means (7) does not substantially impede vision of the goods (5) through the clear plastics lid (3) and leaves substantially the whole of the surface of the goods (5) exposed to the gas. The strand means (7) may be individual strands or may be a mesh or may be a web of plastics with a series of slits or openings therein which is then stretched to provide strand like portions which contact the goods (5). A method of producing the packaging and a package apparatus therefor are also disclosed.

Title: Commingled waste separation apparatus and methods
Inventor: TYLER MIKE W
IPC: B07B9/00
Filed: 1992-04-23
Abstract: COMMINGLED WASTE SEPARATION APPARATUS AND METHODS     ABSTRACT OF THE DISCLOSURE         Separation apparatus and methods separate ferrous, glass, plastic and aluminum articles in kind from each other when all articles are presented in a commingled stream.          Ferrous articles are first removed by magnetic apparatus.          The remaining commingled stream of glass, plastic and aluminum articles are conveyed over a vibratory screen for removal or residue materials not first removed prior to ferrous article separation.  Plastic and aluminum articles are lifted away from glass articles in a vertically moving air column of a closed loop air flow system.  The glass is conveyed past the column for further separation and collection while the plastic and aluminum articles are discharged together from a centrifugal classifier portion of the closed air loop.  Large plastic articles are first removed from the combined plastic and aluminum, then aluminum articles are separated from the remaining smaller plastic articles.  Aluminum articles are collected while the larger and smaller plastic articles are recombined, compacted and collected.  Plastic and aluminum are alternately separated by a trommel.  Alternative component layouts are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         A battery-operated sensing and control circuit for a toilet room device such as a flush valve which is operated by an electric solenoid includes a continuously operable primary sensor and an intermittently operated secondary sensor.  The primary sensor detects the presence of a user adjacent the toilet room device and starts a timing cycle. The secondary sensor is only powered up during the timing cycle and as soon as the secondary sensor has detected a user in front of the toilet room device, the timing cycle is terminated.  All components, including the sensors, the timing device and the electric operator, are powered by a battery.

Filed: 1991-04-05
Abstract: Dispositif de retenue de poinçon (20) amélioré dans lequel une plaque d'appui (24) s'étend sur une surface relativement grande pour dissiper la force émanant d'un poinçon (64). Un corps de retenue (22) et la plaque d'appui sont reliés l'un à l'autre de façon permanente et comportent des passages (38, 40, 42, 44 et 46) qui sont finalement meulés après avoir été fixés à demeure. Ce dispositif permet d'avoir des passages dans la plaque d'appui et dans le corps de retenue bien alignés durant la constitution du dispositif de retenue de poinçon. Comme la plaque d'appui dissipe la force sur une surface relativement grande, le dispositif de retenue de poinçon peut être utilisé dans des conditions plus sévères que les dispositifs de retenue de poinçon de l'art antérieur. Un passage de ressort (56) est fermé par un élément étanche (79) inséré dans la plaque d'appui, ce qui permet l'utilisation de ressorts standard (82).

Title: Sonet ds-n desynchronizer
Inventor: REILLY BRIAN F
IPC: H04J3/00
Filed: 1992-10-09
Abstract: A  SONET/DS-N  desynchronizer  and  method  for receiving  an  incoming  stream  of  SONET  (Synchronous Optical  NETwork)   data,  having  a  controller  for controlling either a direct digital synthesis circuit that  provides  a  desynchronized  clock  for  smoothly adapting the rate at which data is retrieved from a data buffer to the rate at which the incoming SONET data is stored in the data buffer.   To minimize jitter and buffer spills (i.e., data overruns or underruns), the frequency and phase  of the desynchronized clock  is constantly varied to match the variations of the data rate of incoming SONET data.  The DDS circuit generates the desynchronized clock, which has a center frequency equal to a predetermined frequency of a reference clock, whose phase is advanced or retarded in accordance with the magnitude of a tuning word supplied by a controller, which implements either a linear, non-linear, or fuzzy logic control algorithm.   The controller periodically updates the tuning word in response to status variables to adjust the frequency of the clock output of the DDS circuit.  In  an  alternative  embodiment,  a  digital voltage controlled oscillator is used in place of the DDS circuit.

Inventor: GREENE LEONARD A
IPC: B42F1/10
Filed: 1992-12-29
Abstract: ABSTRACT OF THE DISCLOSURE     A holder for long slender implements such as pencils and pens is disclosed.  The holder comprises a support member which is preferably a thin web having opposed side surfaces.          The web includes at least one opening that communicates with each of the side surfaces.  Each side of the opening is surrounded by a plurality of flexible fingers which extend away from each side surface in a converging relationship so that the flexible fingers form a hollow frusto-conical shape that is preferably divided into equal segments.  A long slender implement inserted through an opening in an outer end of the frusto conical shape forces the outer ends of the flexible fingers outward.  The pressure exerted by the flexible fingers holds the long slender implement securely.          The holder may be provided with a resilient clip, an adhesive or a magnetic base for attaching the holder to a variety of suitable surfaces.

Title: Alumina-fiber-reinforced ceramic materials and production process thereof
Inventor: IWANAGA KATSUSUKE
IPC: F28F21/04
Filed: 1992-05-08
Abstract: Abstract Described herein is a process for producing an alumina-fiber-reinforced ceramic material which has a high fiber content, high strength, excellent heat resistance, corrosion resistance, and thermal shock resistance, and features a high alumina purity.     A filament yarn of long continuous .alpha.-alumina fibers having a high alumina content is impregnated with a slurry, which contains a water-soluble aluminum compound, an acid such as acetic acid or lactic acid and a water-soluble organic binder component, all dis-solved in the slurry, and aluminum powder of a primary particle size not greater than 1 µm dispersed in the slurry.  The slurry impregnated filament yarn is wound around a core and then dried.  The resultant green body is then sintered.     A green body of a desired shape can be obtained easily, because its forming is carried out by winding a filament yarn or the like around a core.  In addition, because of the high fiber content, shrinkage is small upon sintering so that a ceramic-fiber-reinforced ceramic material with stable quality can be obtained.

Title: Method and apparatus for measuring gas flow using boyle's law
Inventor: WOODWARD W STEPHEN
IPC: G01F3/36
Filed: 1993-02-23
Abstract: A gas flow meter uses the principle of Boyle's law to measure the gas flow rate along a path. Gas flows through a valve into a reservoir until the pressure is maximized in the volume. The valve then vents the reservoir to ambient while blocking the inlet path. The pressure at maximum and minimum values is measured by a pressure sensor and used to generate the flow rate signal. An enlarged volume in the inlet path limits the pressure rise during the exhaust phase of the measurement cycle.

Ils permettent également, en l'absence d'agents de transfert, de synthétiser avec une activité accrue des polymères de très hautes masses moléculaires. Ces procédés de polymérisation donnent des résultats particulièrement avantageux dans le cas du propylène. Pas de figure.
