Title: Variable heat conduction device to be placed between a heating platen and a cooling platen of a machine such as a press
Inventor: CUSSON PHILIPPE
IPC: B22D19/00
Filed: 1992-02-10
Abstract: DESCRIPTIVE ABSTRACT            In a machine such as a press having at least one heating platen and one cooling platen, it is proposed to place between the said platens a variable heat conduction device (22a), when the operation of the machine requires a phase of heating the part without the application of pressure, followed by a phase of cooling the part under pressure. This device (22a) has two thermally conductive plates (32a, 34a), normally separated by a space under vacuum (52a) under the action of at least one deformable member (36a), which can be elastic or plastic. The application of the pressure passes the device (22a) from a ther-mally insulating state to a thermally conductive state.            (Fig. 2) SP 6803.69 GP

Inventor: PEREGO LUCIANO
IPC: G11B15/68
Filed: 1992-02-17
Abstract: In a cassette loading machine several loading modules carry out the loading of a predetermined amount of use tape into the individual cassettes, said tape being continuously supplied from a pancake mounted on a support hub.  When one of the pancakes mounted on one of the hubs is out of tape, the intervention of a manipulating unit occurs and said unit picks up, by means of a grasping and release member carried by a supply module, a new pancake filled with use tape from a storage unit located sideways.  The manipulating unit moves close to the out of tape pancake and removes it from the respective support hub with the aid of a grasping member carried by a discharge module.          Them the new pancake filled with use tape is mounted onto the support hub in place of the out of tape pancake.

Title: Automatic closing device for a patio screen door
Inventor: OUELLET YVES
IPC: E05F1/02
Filed: 1992-02-18
Abstract: AUTOMATIC CLOSING DEVICE FOR A PATIO SCREEN DOOR   ABSTRACT            A device for automatically closing a patio screen door comprises a tubular sheath in the form of a molding equipped at its top end with a vertical pulley rotatably mounted thereto and which extends substantially  parallel  to  the  screen  door.    The sheath is adhesively mounted to the inner frame of the wall defining the opening for the patio doors at the side thereof onto which abuts the screen door, when closed.   A cable which engages the pulley is adapted to be fixed at one of its ends to the upper frame of the screen door and at its other end to a weight which suspends  from the pulley within  the sheath.  Therefore, the opening of the screen causes the weight to raise,  whereby,  upon  releasing the open screen door,  the weight automatically causes the  screen  door  to  displace  towards  its  closed position.  The weight includes sections which can be severed and thus removed therefrom to lower its mass if the user wishes to reduce the speed at which the screen door closes.

Patent CA-2064478-A1 (CA)
Title: Ophthalmic composition
Inventor: CLARK ABBOT F
IPC: A61P27/02
Filed: 1990-07-25
Abstract: Pharmaceutical compositions useful in the treatment of ophthalmic inflammation and methods of treating ophthalmic in-flammation with those compositions ar disclosed. The compositions contain a combination of a glucocorticoid and an angiostatic steroid. The angiostatic steroid substantially prevents any significant increases in intraocular pressure which might otherwise he experienced by the patient as a side effect of the glucocorticoid component of the compositions. The therapeutic interaction of the two components therefore allows the potent anti-inflammatory properties of the glucocorticoids to be utilized without fear of ele-vating intraocular pressure.

Patent CA-2077425-A1 (CA)
Inventor: SAKAI ICHIRO
IPC: F16H61/662
Filed: 1992-09-02
Abstract: In a control system for controlling a gear ratio of a multi-step geared or continuously variable automatic trans-mission, the driver's intention to decelerate is inferred by carrying out a first fuzzy reasoning using a degree of throttle opening or the like and then the target gear ratio is determined by carrying out a second fuzzy reasoning using parameters including the inferred driver's intention to decelerate.  The first fuzzy reasoning is carried out using fuzzy production rules classified by operating conditions such as a road profile and a vehicle speed.   The inferred driver's intention to decelerate is canceled if braking is discontinued.  Thus the control ascertain the intention of the driver and is thus possible to achieve sophisticated shift scheduling well matched to the sensibilities of the driver.

Abstract: Abstract of the Disclosure A  system  is  provided  for  heating  non-metallic material or a discrete layer of the non-metallic material.  Microwave energy is introduced into an enclosure defining a first cavity and capable of substantially containing the microwave energy.  A semiconductive sheet is positioned at the bottom of the first cavity.  Thermal insulation overlies the semiconductive sheet.  A second cavity is defined by the undersurface of the semiconductive sheet and flexible microwave shielding in the form of a skirt which  is  attached  to,  and  depends  from,  the enclosure.  The flexible shielding is composed of a material  which  also  substantially  contains  the microwave energy.
