Patent CA-2105628-A1 (CA)
Inventor: FORGASH ANTHONY R
IPC: B29B9/06
Filed: 1993-09-07
Abstract: A strand pelletizer for cutting thermoplastic strands into pellets is provided.  The strand pelletizer has a housing that includes a base, a pivotable cover, and a moveable end wall.  The pivotable cover and the movable end wall may be opened without the use of tools to provide access to the interior of the pelletizer cutting chamber.          The movable end wall is both slideable and pivotable over a fixed dowel pin within the housing base.  The moveable end wall houses the feed rolls for the pelletizer and also houses the strand inlet to the pelletizer.  After the cover is raised, the moveable end wall may be pivoted away from the cutting chamber to permit cleaning of the interior of the cutting chamber, particularly the critical area below the lower feed roll of the cutting chamber.

Title: Air conditioning and refrigeration apparatus utilizing a cryogen
Inventor: ROEHRICH ROLAND L
IPC: F25B29/00
Filed: 1993-11-26
Abstract: ABSTRACT OF THE DISCLOSURE        A refrigeration system associated with a condi-tioned space to be controlled to a predetermined set point temperature via heating and cooling cycles.  The refrigera-tion system includes a fluid flow path through which a predetermined fluid is circulated.   The fluid flow path includes first, second and third heat exchangers. The first heat exchanger is disposed to condition air of the condi-tioned space, the second heat exchanger is in heat exchange relation with cryogenic cooling apparatus, and the third heat exchanger is in heat exchange relation with heating apparatus.   The  first  and second heat exchangers  are interconnected  when  the  conditioned  space  requires  a cooling cycle, and the first and third heat exchangers are interconnected  when  the  conditioned  space  requires  a heating cycle.  Cryogen of the cryogenic cooling apparatus is thus not expended to heat the conditioned space, nor used for defrosting purposes.

Title: Roughness detector
Inventor: POPIL ROMAN E
IPC: G01N21/892
Filed: 1992-06-03
Abstract: ABSTRACT OF DISCLOSURE  ROUGHNESS DETECTOR To detect roughness on a travelling surface of a web such as paper a beam of polarized light is directed at an angle onto the web and focused by a focal lens to illuminate a spot on the surface and a specularly reflected component of the light is collected through a second lens focused on the spot. A detector is aligned to receive a portion of the specularly reflected collimated light from the spot passing through a selecting aperture and generates a signal depending on the intensity of the specular light passing through the aperture and received by the detector thereby to provide an indication of the roughness (or smoothness) of the surface.

Abstract: Dans un effort de construire des maisons de plus en plus chaudes à un coût de plus en plus avantageux, de nombreux autoconstructeurs utilisent des ballots de paille en guise d'isolant qu'ils enrobent de mortier de façon à ériger les murs de leurs future maison. Côté énergétique et confort, ces murs ont une résistance thermique de R-40 soit deux fois supérieure à la norme et des caractéristiques d'échange de l'air ambiant étonnantes. Le plus, le coût de la paille et du mortier, presque dérisoire, permet d'ériger une structure autoportante avec très peu d'investissements. La présente invention, les blocs de paille et mortier fabriqués en atelier et suffisamment léger pour être manipulés par un seul homme peuvent être assemblés comme des blocs de ciments sans affecter les performances d'isolation et de solidité de la structure.

Abstract: Un dispositif, qui permet d'améliorer la qualité de l'air de combustion dans un moteur à combustion interne, comporte un boîtier (1) parallélépipédique, construit en matériau magnétique, qui comprend un orifice d'entrée (5) sur une de ses faces latérales, et un orifice de sortie (6) sur la face opposée. Un passage (8) pour l'air, ménagé dans ce boîtier, établit une communication entre ces orifices d'entrée (5) et de sortie (6). L'orifice de sortie (6) du boîtier est raccordé à un point situé le long d'une conduite d'aspiration de l'air de combustion d'un moteur à combustion interne ou d'une installation de combustion. Des aimants permanents (13) opposés sont fixés dans ce boîtier de façon à maintenir dans le passage (8) les mêmes polarités que les leurs, et des axes (11) construits en matériau magnétique sont dressés dans ce passage. De plus, fixés de manière lâche sur chaque axe (11), on trouve un premier cylindre (16) et un deuxième cylindre (15) métalliques, qui présentent des tendances différentes à l'ionization, sont séparés par un intervalle étroit et peuvent être librement déplacés par des courants d'air traversant le passage. Lorsqu'un moteur à combustion interne tourne au ralenti, l'air est forcé dans le passage depuis l'orifice (5) d'entrée grâce à une soufflante (30). Un champ électromagnétique se forme dans ce passage et les ions métalliques des cylindres se mélangent à l'air. De plus, l'oxygène de l'air de combustion se transforme en oxygène naissant par décharge.

Title: Variable outer diameter wheel for vehicles
Inventor: MATSUDA YUTAKA
IPC: B60B19/04
Filed: 1995-01-26
Abstract: A variable outer diameter wheel includes a generally cylindrical pipe or drum having four equally spaced penetrating holes or receiving parts in the cylindrical wall, a diaphragm sealing means corresponding to each of the penetrating holes and fitted to the pipe support, and sliders forming a wheel peripheral face so that the sliders can smoothly slide in the penetrating holes.  The sliders are pushed or activated and moved outward from the pipe in a direction so the wheel outer diameter is enlarged by compressed air supplied through a passage and a hole provided in an axle which support the wheel.  Exhausting the compressed air causes the wheel outer diameter to decrease and restores the wheel to its original size.  Variable outer diameter wheels permit safe operation of vehicles on frozen, snow-clad or irregular surfaced roads.

Title: Control of dilution lines in a dilution headbox of a paper making machine
Inventor: HELLSTROM AKE ARVID
IPC: D21F1/08
Filed: 1995-05-31
Abstract: Pinch valves having a flexible, constrictable sleeve are used to control a dilution headbox for a paper making machine. A variety of pinch valves may be used in the present invention with the pinch valves being actuated by pneumatic or hydraulic pressure or by mechanically pinching the valves' sleeves by means of rams driven by stepper or linear drive motors.  For pneumatic control, dynamic differential pressure drops are measured across the valves to determine flow rate through the valves.  A pinch valve, referred to herein as a torsional pinch valve, is disclosed for dilution headbox control.  In one form, a first end of a sleeve is fixedly mounted in a support frame and the second end of the sleeve is mounted for rotation in the frame.  A driver rotates the second end of the sleeve such that a flow path through the sleeve is controlled.  The flow path is a maximum when no torsion is placed on the sleeve and is reduced to substantially zero by sufficien~ rotation.  In another form, first ends of two sleeves are secured into a support frame such that the sleeves are in axial alignment with one another.  The second ends of the sleeves are secured to an annular collar or sleeve support member which is mounted for rotation between the fixedly mounted first ends.  By rotating the annular collar, the cross section of the flow path is controlled.
