Patent CA-2295437-A1 (CA)
Title: Acceleration protective suit
Inventor: REINHARD ANDREAS
IPC: A41D13/00
Filed: 1998-04-23
Abstract: The suit according to the invention comprises, as well as a textile lining and a skin made of low stretch textile material, a double walled skin lying between them, made of moderately stretchable watertight material. The latter is made of walls, which are joined together at connection positions for instance by welding. The mutually communicating hollow spaces arising thereby in the double walled skin are filled with a fluid. The suit is closed by zip fasteners (17, 19) and by shoulder straps (18). Short zip fasteners (26) in the crotch facilitate putting on the suit. The front part (20), armlets (21) thorax part (24) can be equipped with various structures of connecting positions, which however are arranged similarly on both halves of the suit. All the named parts (20, 21, 24) can be provided each with two valves (22, 23) for filling with the fluid and for ventilation. The fluid filled and pre-tensioned, by the outer skin, double walled skin builds up a compensating pressure on the body proportional to the acceleration.

Title: Heater door mechanism for infant warming apparatus
Inventor: MACKIN MICHAEL H
IPC: H05B3/00
Filed: 2000-03-13
Abstract: An infant warming apparatus that functions both as an infant incubator as well as an infant warmer. The apparatus has a heater that moves vertically with respect to an infant support during the change in function between an infant incubator and infant warmer. A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions.  The heater also has a door or doors that are open when the heater is at or nearing the upper position so that the heater can direct energy toward the infant to warm the infant when acting as an infant warmer. The doors close at or shortly after the heater commences movement to the lower position. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel and prevents the further radiating of infrared energy towards the infant. The mechanism operates automatically without any reminder to the user or action by the user. Preferably the actual opening and closing of the doors takes place within a short distance from the upper position, more preferable within about 6-8 inches form the upper position. A vent is also provided in the heater housing that ventilates the housing when the heater is in its upper position and closes to confine the housing when the heater is in its lower position. A mechanism automatically closes the vent when the heater moves from its upper position to its lower position and opens the vent when the heater moves from its lower position to its upper position. In the preferred embodiment, the vent is biased towards its open position and the doors are biased towards their open positions.

Title: Method for changing bcch carrier frequency without disturbing ongoing call traffic
Inventor: CERWALL CARL PATRIK
IPC: H04W24/02
Filed: 1998-08-07
Abstract: A method for establishing a new broadcast control channel (56) carrier frequency within a cell without disturbing ongoing call traffic is disclosed.  A cell having a base station (34) transmitting broadcast control channel (56) data over an existing BCCH carrier frequency establishes a second BCCH carrier frequency within the cell. During a first time period BCCH data is transmitted on the existing first BCCH carrier frequency. During a second time period, both the existing and new BCCH carrier frequencies carry BCCH data to enable surrounding mobile stations (14) to detect and recognize both carriers. The transmission of the old BCCH carrier frequency is then discontinued during a third time period, such that the broadcast control channel (56) data is only transmitted on the new BCCH carrier frequency.

Title: Fuel cell gas sensors
Inventor: ULKEM ILHAN
IPC: G01N33/00
Filed: 2000-06-23
Abstract: A fuel cell gas sensor for detecting gases such as Hydrogen (H2) and Carbon Monoxide (CO) comprises a main body (10) in which are mounted a protection membrane (11), a working electrode (12), electrolyte (13), a counter electrode (14), a protection membrane (15) and respective contacts (16). A catalyst disk (17a) or a very low impedance fuel cell (17b) is placed between the counter electrode (14) and the protection membrane (15). The membrane (15) slows down the flux of gases onto the counter electrode (14). The catalyst disk (17a) eliminates chemically while the fuel cell (17b) eliminates electrochemically the gases to be detected that permeate through the protection membrane (15).      This arrangement makes it possible to detect the gases in places where the gases to be detected are able to reach both the working electrode (12) and the counter electrode (14).

Abstract: A microcellular injection blow molding system and method, and microcellular blow molded articles produced thereby, are described. The system is equipped to extrude microcellular material that changes in thickness, material density, or both in the machine direction while maintaining a constant pressure drop rate during nucleation just prior to extrusion, providing the ability to produce consistent uniform microcellular material independent of material thickness. The systems and methods are particularly useful in production of strong, thin-walled, non-liquid-permeable, opaque containers that do not contain reinforcing agent, chromophore, or residue of chemical blowing agent or chemical blowing agent by-product. Semi-crystalline microcellular foams that include a midlevel amount of nucleating agent, and methods of their production, also are provided. The microcellular foams can be produced in typical polymer processing techniques such as extrusion, injection molding and blow molding. The foams exhibit excellent mechanical properties and can be formed over a broad range of density into a number of different foam articles. Also provided are high-density polyethylene foams and dies that are suited for use with HDPE, foams.
