Patent CA-2174466-A1 (CA)
Inventor: LARSSON KRISTER
IPC: H02P23/24
Filed: 1996-04-18
Abstract: The invention concerns a method and an apparatus for actuating a plurality of synchronous motors which are connected to a common power supply and which are respectively used for displacing an element between two limit positions and have a connection for forward motion, a connection for reverse motion and a neutral connection. The connection between the forward or reverse motion connection which is in use and the power supply is interrupted by means of a limit switch which responds when the displaced element reaches a limit position. The connection between the reverse or forward motion connection which is not in use and the power supply remains interrupted during non-use. A gated switch is connected upstream of the connection for forward motion and another gated switch element is connected upstream of the connection for reverse motion.      The gate input of the switch is connected to a respective control circuit which includes the respective limit switch. The advantages of the invention are that electromagnetic actuating members can be connected in parallel with this type of synchronous motor by way of limit switches without malfunctions occurring when the limit switches respond. The amount of wear of the synchronous motors is reduced and the service life thereof is thereby increased. The level of power consumption is reduced and the amount of noise developed is decreased.

Patent CA-2180026-A1 (CA)
Title: Unit ventilator and heater
Inventor: SUTTON PETER JAMES
IPC: F24H3/12
Filed: 1996-06-26
Abstract: A space heater and ventilating unit for a room employs a hot water heater that includes a burner and a first heat exchanger for heat exchange between water supplied to the heater and the combustion gases of the burner.  An air-to-air heat  exchanger  has  a  first  set  of  air passageways  for delivering exhaust air from the room to an exhaust air outlet and a second set of air passageways through which supply air passes.  A first fan draws the exhaust air through the first set of passageways where this air can warm the supply air.  A second fan passes the supply air through the second set of passageways.  An additional water-air heat exchanger mounted downstream of the second set of passageways heats the supply air to a desired temperature.  A pipe delivers hot water from the heater to the additional heat exchanger and there are means for returning the water from this heat exchanger to the heater.  In a preferred embodiment, there is a water storage tank that is separate from the heater and a diverting valve that can direct hot water directly to the storage tank, when appropriate, so that it does not flow to the additional heat exchanger.
Patent CA-2180211-A1 (CA)
Inventor: LATVIS STEVEN D
IPC: B23K9/32
Filed: 1996-06-28
Abstract: An engine driven welding machine has two paths of cooling air flowing therethrough that are segregated from each other.  Both paths have their inlets at the electrical end of the welding machine, and both paths have their exhausts at the machine engine end.  The first path directs air through a passage containing a rectifier and into a blower housing.  The blower housing divides the first path into a first portion that supplies combustion air to the engine.  A second portion of the first path directs air over outer walls of the engine block and head and into a hot air exhaust box, from which the air exhausts from the machine.  The second path directs air over a stabilizer and into a generator.  From the generator, the second path leads to an engine compartment, from which the air exhausts.  The first and second paths direct the cooling air through multiple turns that reduce machine noise.

Title: System for optimizing continuous positive airway pressure for treatment of obstructive sleep apnea
Inventor: RAPOPORT DAVID M
IPC: G06F17/00
Filed: 1995-05-16
Abstract: In the treatment of obstructive sleep apnea, a method and apparatus (70) are disclosed for optimizing the controlled positive pressure to minimize the flow of air from a flow generator (86) while still ensuring that flow limitation in the patient's airway doest not occur. In particular, the invention relates to a breathing device (70) and method of use to adjust a controlled positive pressure to the airway of a patient by detecting flow limitation from analysis of an inspiratory flow waveform. Once the presence of flow limitation has been analyzed the system determines an action to take for adjustment of the controlled positive pressure. The pressure setting is raised, lowered or maintained depending on whether flow limitation has been detected and on the previous actions taken by the system. The preferred breathing apparatus (70) consists of a flow generator (86), a flow sensor (72), an analog to digital converter (78), a microprocessor (80), and a pressure controller (82, 84), a patient supply hose (74), a nasal fitting, and, optionally, a pressure transducer (90). Using the method of the present invention, the microprocessor (80) adjusts the air pressure in the patient supply hose (74) when flow limitation is detected in the airway of the patient.

Title: Fibers and fabrics incorporating lower melting propylene polymers
Inventor: STAHL GLEN ALLEN
IPC: B32B7/027
Filed: 1995-05-19
Abstract: Propylene homopolymers and copolymers formed by metallocene catalyst system exhibit generally lower melting behaviour than previous propylene polymers. This lower melting behaviour will be of use in the fabrication and use of fibers and fabrics that depend upon either lower melting behaviour in general or upon a melting point differential between two fabrics or fibers to achieve bonding. Such fibers are, for instance, chenille or tufted cord, core and sheath. Fabrics such as spunbonded and meltblown, when combined in SM or SMS fabrics will show bonding at lower temperatures with fewer pinholes. Such fabrics may also be bonded by adhesives such as hot melt, water based and extruded polyolefins. Combinations of Ziegler-Natta catalyzed and metallocene catalyzed polymers are contemplated.

Title: Prosthetic spinal disc nucleus
Inventor: RAY CHARLES D
IPC: A61F2/00
Filed: 1995-10-17
Abstract: An elongated, pillow shaped prosthetic spinal disc nucleus body (10) for implantation into a human intervertebral spinal disc (32), made of a hydrogel core (12) and a flexible constraining jacket (14) surrounding the hydrogel material core (12) that permits the hydrogel core (12) to expand and contract. The hydrogel core (12) has a length approximating the sagittal diameter of a nucleus of the human disc, a width less than the length, and a height less than the length or width. The hydrogel core will expand            (See fig. I) and contract in a desired fashion as it imbibes and expels fluids in response to various loads placed upon the spinal tract. The constraining jacket (14) is porous to allow fluids to pass through to the hydrogel core (12), but prevents the hydrogel (12) from escaping, thus fostering the natural physiology of the human invertebral disc. By implanting two prosthetic spinal disc nucleus bodies (10) side-by-side into a damaged disc (32) of a human spine, both height and motion can be maintained.
