Title: Automatically rinsing baby bottle
Inventor: BRAL HOOSHANG
IPC: A61J9/00
Filed: 1995-10-30
Abstract: A nursing bottle for automatically rinsing a baby's teeth by independently dispensing first and second liquids, includes a nursing bottle having a nipple, a rinsing device having a dispensing end and a buoyant valve attached to the dispensing end for retaining the second liquid within the rinsing device while the nursing bottle receives the first liquid. The valve retains the second liquid within the rinsing device when the bottle is at least substantially inverted due to a buoyant force produced by the valve against the dispensing end. The buoyant force of the valve is greater than the force of gravity which acts on the valve until the first liquid is substantially dispensed from the bottle. After which, the force of gravity overcomes the buoyant force of the valve and the valve is pulled towards the nipple by the force of gravity. As a result, the valve automatically releases the second liquid from the rinsing device and into the nipple to rinse the baby's teeth.

Title: Incisor-dilator with tapered balloon
Inventor: LARY BANNING GRAY
IPC: A61M25/10
Filed: 1997-07-03
Abstract: The present invention is a device for incision and dilation of stenotic segments within the vascular system of a patient. Structurally, the present invention includes a rigid ellipsoidal dilation probe mounted at the distal end of a catheter. A series of longitudinally oriented blades project radially from the surface of the probe. A tapered inflatable balloon is also mounted on the catheter in a position that is proximal to the dilation probe. In use, the probe and catheter are advanced over a guidewire to reach the targeted stenotic segment. The probe and blades are then advanced through the stenotic segment to incise the stenosis. The balloon may then be inflated to adopt a tapering fusiform shape, allowing the balloon to be advanced through the stenosis to further dilate the stenosis. Alternatively, the balloon may be positioned across the stenosis and inflated to dilate the stenosis. The fusiform shape of the balloon matches the tapering geometry of many coronary arterial vessels, decreasing the chances that a segment of the vessel will be overpressurized by the inflating balloon.

Title: Method and apparatus for producing coreless rolls of sheet material
Inventor: SALZSAULER EDWARD R
IPC: B65H75/24
Filed: 1998-01-23
Abstract: A roll of sheet material, such as plastic film wrap, having an inner layer wound at low tension and an outer layer wound under greater tension provides a coreless roll.  Eliminating the need for a core reduces the cost of producing rolls of sheet material, and reduces the weight and outer dimensions of the roll with a consequent reduction in shipping and storage costs. An apparatus and method for producing such a roll, from a pre-wound master roll or as part of a production lint for forming the sheet material, involves varying the longitudinal tension applied to sheet material as it is wound onto an expandable mandrel. After the roll has cured, the mandrel is collapsed and disengaged from the roll to provide a coreless roll.

Patent CA-2237197-A1 (CA)
Inventor: BARTON JAMES STEPHEN
IPC: G01N21/55
Filed: 1996-11-29
Abstract: A substance sensor comprises an optical fibre having a core (1) and a cladding (2) having a lower refractive index. A layer (4) of cladding is left between a sensor material (3) and the core (1). The thickness (t) of the layer (4) is sufficiently small that the sensor material (3) lies within the evanescent wave which occurs within the cladding (2) when optical radiation is conducted through the core (1). The refractive index of the sensor material (3) varies in the presence of a substance to be sensed over a range which extends on either side of the refractive index of the cladding (2). When its refractive index is lower than that of the cladding the sensor material operates, as far as the radiation is concerned, similary to the cladding (2). Conversely, when its refractive index is higher than that of the cladding (2) the sensor material (3) couples out some of the radiation, reducing the transmissivity of the fibre. The sensor material may be polyethylene oxide, in which case the arrangement operates as a humidity sensor.
