Patent CA-2154172-A1 (CA)
Title: A laparoscopic dissection tension retractor device and method
Inventor: GORMAN WILLIAM
IPC: A61B17/34
Filed: 1994-01-25
Abstract: A minimally invasive retractor and dissector (10) for internal surgical use on a patient has a tubular support (11) for passing into the body; the tubular support (11) has a passage (16) for access along an axis "A" thereof during operative procedures on the patient's internal tissue. A proximal end (12) on the tubular support (11) is located outside the patient in position to be accessed by the surgeon when a distal end (13) is inside. One or more jointed articulated members (15) are movably positioned and capable of holding and pulling tissue disposed beyond the distal end (13) and each member has a distal tip (17) to hold tissue. An instrument capable of moving independent of any member functions cooperatively on the tissue and passes through the passage (16) from the proximal end (12) to beyond the distal end (13) as the members position the tissue. The instrument is a surgical tool and the tissue is maneuvered by the members within the body into a position relative to the tool. A control (19) at the proximal end (12) manipulates the members relative to the axis "A" permitting holding and pulling tissue disposed beyond the distal end (13); the control (19) is capable of moving the instrument independent of the members for operating on the held and maneuvered tissue. A grip (34) manipulates the members and positions the instrument. A method for using the minimally invasive retractor and dissector (10) has the steps of making an opening for a tubular support (11) to pass into the body, leaving the proximal end (12) on the tubular support (11) outside the body, positioning the distal end (13) thereof inside, and moving members carried on the tubular support (11). Holding and pulling tissue disposed beyond the distal end (13) and using the passage (16) for access along the axis thereof for operating on internal tissue are added steps. Another step is moving an instrument in the passage (16) independent of the members.

Title: High performance motorized water ski
Inventor: MONTGOMERY ROBERT E
IPC: B63B35/79
Filed: 1995-03-02
Abstract: A high speed motorized water ski (10) has a hull (16) having a bow (18), a stern (20) and a deck (22) sized for accommodating a standing rider (12). A jet pump (100) is mounted in the stern (18) for discharging a propelling stream of water outwardly from the stern (18) in a direction generally parallel to a longitudinal axis (144) of the hull (16). A motor (108) is mounted within the hull (16) for driving the jet pump (100). The standing rider controls the speed of the motorized water ski (10) by means of an arm pole (26) having one end attached to the hull (16) near the bow (18). A hand grip (132) is attached to the other end of the arm pole (26) for enabling the standing rider to control motor speed and for providing stabilization to the standing rider's stance on the deck (22). The motor (108), jet pump (100) and other components of the motorized water ski (10) are mounted in the hull (16) to define a center of gravity so that when a rider of average weight stands on the deck (22), the composite center of gravity (120) of the motorized water ski (10) and rider (12) is beneath the deck (22) in order to enable the standing rider (12) to turn the motorized water ski (10) solely by a shift in rider stance on the deck (22).

Abstract: A variable color LED device emits variations of luminescent colors, and an LED color control device (current control circuit) controls the emission (color and intensity) from the variable color LED device.          Luminescent diodes R,  G,  and B are provided in a single variable color LED device 10 to emit light of red, green, and blue.  The electric current flowing to the luminescent diodes is controlled for each color by a current control circuit 15.  The current control circuit   15   comprises,   fox   example,   variable resistances 16r, 16g, and 16b.  Optionally controlling the electric current through the variable resistances allows the quantity of light of each of optical three primary colors, thereby emitting a mixed color from the luminescent diodes of the variable color LED device 10.  Thus, variations of luminescent colors can be successfully emitted.  The device can be used both indoors and outdoors as a display picture element for a color display device,  etc.   Its  small picture element realizes a precise image.

Inventor: COOKE PHILIP R
IPC: H02H7/06
Filed: 1995-09-19
Abstract: A shorted diode protection system for a traction vehicle propulsion system including a synchronous generator having armature (15) and field windings (12) and a bridge rectifier circuit (64) coupling the generator armature windings (15) to a traction motor employs a normally nonconducting solid-state controllable electric valve (71) in parallel with the generator field windings. When a rectifier diode of the bridge rectifier circuit fails short, an a-c current is reflected into the generator field winding circuit. Upon detection of this reflected current, the valve is switched into a conducting state, thereby limiting the voltage on the generator field windings.

Patent CA-2175677-A1 (CA)
Title: Limescale removing composition
Inventor: BOWDEN ELAINE ANN
IPC: C11D3/20
Filed: 1994-11-12
Abstract: The invention provides limescale-removing compositions of pH 1-4, comprising maleic acid, a nonionic surfactant, an anionic surfactant, a perfume and an alpha-hydroxy carboxylic acid (preferably citric acid). It is believed that the combination of alpha-hydroxy carboxylic acid with maleic acid is less toxic and less prone to decomposition than an equivalent amount of maleic acid, i.e. an amount which provides comparable limescale-removing performance. However, it is also believed that the alpha-hydroxy carboxylic acid interacts with the nonionic surfactant to destabilise the product in the absence of the anionic surfactant.  Thus, there is believed to a synergistic interaction between the components which provides a stable and effective composition containing the alpha-hydroxy fatty acid as a partial replacer for the maleic acid

Title: Treatment beam handpiece
Inventor: COLEMAN TONY DAVID
IPC: A61B18/22
Filed: 1994-12-21
Abstract: A dermatology hand piece (10) delivers a treatment beam of optical energy to a lesion. The hand piece (10) has the ability to selectively determine whether or not the treatment beam is delivering optical energy to a lesion or to healthy tissue. This is achieved without visual inspection of the skin surface by a physician. Slight variations in tissue can be detected and treated. A base line is established for the treatment area by taking a reading of healthy skin. Normal tissue, falling below the base line, does not receive optical energy. Substantially all of a lesion receives the proper amount of optical energy in the treatment beam, while healthy tissue does not receive a dosage of optical energy.
