Patent CA-2085507-A1 (CA)
Title: Excavation Apparatus
Inventor: GYORI WESLEY
IPC: E02F5/00
Filed: 1992-12-16
Abstract: An excavation apparatus includes a tank partitioned into two isolated chambers. One of the chambers is adapted to hold fresh water and communicates with a flexible wand to be carried by operating personnel.  The other chamber is adapted to hold excavated material and communicates with a flexible hose also to be carried by operating personnel.  A single, positive displacement vacuum pump driven by a motor is selectively connectable to one or both chambers through a series of valves and hoses. Depending on the valve positions, either the intake or exhaust port of the vacuum pump is in communication with one or both the chambers.  The vacuum pump can therefore by used to fill the front chamber with fresh water as well as to pressurize the front chamber so that the water held therein can be discharged through the wand under pressure sufficient to dislodge earth at the excavation site. The vacuum pump can then be used to draw the dislodged earth and discharged water into the other chamber.  When the other chamber becomes full, the vacuum pump can pressurize that chamber to discharge the contents therein via the flexible hose at a location away from the excavation site.

Title: Blow molding method and apparatus employing pressurized liquid cryogen vaporized by recovered gaseous cryogen
Inventor: LEE RON C

Filed: 1993-03-04
Abstract: 0230M                                      Dkt. No. 91A426 Abstract An article is formed in a mold by blowing a hot plastic material with  a blowing gas.   A cooling fluid is introduced into the article to cool the article and allow its removal from the mold.   A warmed gaseous form of a cryogen is added to a pressurized  liquid  form of  the cryogen  to  form the cooling fluid by introducing the pressurized form of the cryogen into a jet pump and drawing the warmed gaseous form of the cryogen in the  pressurized  liquid  form  of  the  cryogen.   The  resultant cooling  fluid  circulates  through  the   article   by  being introduced into the article and discharged from the article by two or more blow pins.  Part of the discharged cooling fluid is then  recovered  in  a storage tank.   The cooling fluid, which after cooling the article is composed of  the warmed gaseous form of the cryogen,  is then drawn from the storage tank into the  jet  pump  during   formation  of   the   cooling   fluid. Additionally, the blowing gas can comprise cooling fluid formed in the manner outlined above.  Alternatively, the blowing gas can comprise the warmed gaseous form of the cryogen recovered from the article.

Title: Coating film transfer device
Inventor: TAMAI SHIGERU
IPC: B65H37/00
Filed: 1992-08-28
Abstract: In a case, a delivery reel for supplying a coating film transfer tape and a take-up reel for recovering the coating film transfer tape are rotatably provided, a pointed head for transferring the coating film is projectingly provided at an end of the case.  The delivery reel is constructed such that a delivery cylinder is rotatably fitted over the outer periphery of a boss portion of a driving gear wheel through an elastomeric frictional member and the take-up reel is constructed such that a follower gear wheel being in  meshing engagement with the driving gear wheel is provided over the outer periphery of a take-up cylinder, whereby an end of a coating film transfer tape wound around the delivery cylinder is delivered from the delivery cylinder and reversed at a pointed portion of the head, and wound around the take-up cylinder. When a delivery speed of the coating film transfer tape and a take-up speed go out of balance with the progress of operation, the delivery cylinder is idly rotated with respect to the boss portion of the driving gear wheel through the frictional member, whereby the above-described both speeds are brought into synchronism with each other.  Owing to this, the coating film transfer tape can smoothly run at all times.

Title: Systeme de reglage de siege de vehicule
Inventor: HUGHES DANIEL
IPC: B60N2/12
Filed: 1993-06-04
Abstract: Dispositif de fixation de siège de véhicule, pour sièges comprenant un coussin de siège et un dossier qui s'incline sur le coussin de siège lorsqu'il passe d'une première position relativement verticale à une seconde position relativement repliée. Le dispositif de fixation est constitué d'une coulisse, solidement fixée sur le véhicule, dans laquelle se déplace un coulisseau auquel est solidement fixé le siège. Un câble relie le dossier et le bras d'un dispositif de commande. Lorsque le siège est déplacé vers l'avant pour donner accès aux sièges arrière du véhicule, le câble soulève le bras et le fait passer d'une position neutre à une position relevée, ce qui entraîne simultanément le déplacement d'un galet de came d'une position relevée à une position abaissée. Le galet de came retient le bras en position relevée contre la force exercée par un ressort. Lorsque le siège est ramené en position normale, le galet de came entre en contact avec une came située sur la coulisse ou sur le coulisseau dans une position préétablie, ce qui provoque le déplacement du galet de came, d'une position abaissée à une position relevée. Le bras est alors débloqué et reprend sa position neutre tandis, que le mécanisme de verrouillage de la coulisse peut se verrouiller de nouveau et bloquer le siège dans la position préétablie.
Patent CA-2098644-A1 (CA)
Inventor: JAKLIN HANS
IPC: C04B16/06
Filed: 1993-06-17
Abstract: In reinforced concrete components of high-strength concretes, explosive flaking occurs when stressed in a fire. This can be prevented by providing the concrete of such components with a capillary system, whose substantially linear capillaries have a diameter of at least 3  mu m and a length of at least 5 mm. This capillary pore system can be formed, without impairing the other desired properties of the concrete or mortar, during or after the setting of the concrete or even only under the conditions of the fire stress. This is achieved by means of fibres which form the capillaries by dissolution, softening, shrinkage, decomposition or melting and correspond to the desired capillaries with respect to diameter and length as well as the quantity introduced. Supports produced from such fibre concrete, if appropriate with addition of finely disperse silica, can be classified in fire resistance class F 180-A.

Abstract: A heating sensor is disposed within the pipe wherein a clearance defined between inner wall of the measuring pipe and outer surface of the heating sensor is dimensioned so that the measurement may be free from any influence of a connective heat transfer. Temperatures of the fluid and the heating sensor are measured and a differential temperature therebetween in the steady state is determined. A correlation established between the differential temperature and a thermal conductivity of the fluid is utilized to obtain the thermal conductivity of this fluid.      Alternatively, the differential temperature between the fluid being measured and the heating sensor may be controlled at a constant value and a correlation between a heating value of the heating sensor and the thermal conductivity of the fluid may be utilized to determine the thermal conductivity of this fluid based on an actual heating value of the heating sensor.      A temperature of the fluid staying within the measuring pipe can be controlled by thermostatic means.      The said clearance may be provided by, the heating sensor and the movable spacer adapted to maintain a predetermined gap with respect to outer surface of said heating sensor.
