Patent CA-2218786-A1 (CA)
Title: Solar panel and method of manufacturing thereof
Inventor: VAN DOORN ANDREW
IPC: F24S10/75
Filed: 1997-10-17
Abstract: A method for forming a solar collector includes a panel provided with an inner bore and a deformable metal tube inserted in the bore and mechanically secured thereto by passing a plug or bullet through the tube to deform it outwardly into intimate contact with the panel such as to maximize the heat transfer therebetween and to substantially eliminate any possibility of corrosion by keeping the tube in constant compression. The tube can carry a liquid, such as water or glycol, which is heated by the panel exposed to radiant solar heat. The so formed solar collector typically uses a copper tube and an extruded aluminum panel. A number of parallel conduits connected at their opposite ends to common main inlet and outlet copper pipes may be provided with the panels of adjacent conduits mating together while allowing for relative movement therebetween but without the forming of gaps therebetween.

Title: On site interchangeable neon sign
Inventor: STRAWBRIDGE JON P
IPC: G09F13/26
Filed: 1995-05-02
Abstract: A generally planar base panel member (13) has mounted to its back face a pair of laterally spaced apart chambers (45, 46) whose open fronts are covered by the panel (13). A pair of electrical receptacles (49, 50, 51, 52) in each chamber (45, 46) are arranged in alignment with apertures in the base panel (13). First and second front panels (11, 12) each have a neon tubing configuration (18) mounted on a front side of the panel (13) with the electric end terminals (66) at opposite ends of the tubing configurations (18) projecting through holes in the front panels (11, 12) so that when the front panels (11, 12) are juxtaposed to the front of the base panel (13) the neon tube terminals (66) plug into the receptacles (49, 50, 51, 52). A power supply (53) for neon tubing (18) is mounted to the back face of the base panel member (13). The neon tubing configurations (18) on the individual front panels (11, 12) when plugged into the receptacles (49, 50, 51, 52) form a series circuit which connects across the high voltage output terminals of the power supply (53).

The about 200 kDa outer membrane protein as well as nucleic acid molecules encoding the same are useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a bacterial pathogen that produces the about 200 kDa outer membrane protein or produces a protein capable of inducing antibodies in a host specifically reactive with the about 200 kDa outer membrane protein.
Patent CA-2220434-A1 (CA)
Title: The use of epidermal growth factor as a gastrointestinal therapeutic agent
Inventor: HARDIN JAMES A
IPC: A23K1/16
Filed: 1996-05-09
Abstract: New utilities for epidermal growth factor (EGF) as a gastrointestinal therapeutic agent are described. In particular, EGF is useful in preventing gastrointestinal colonization by pathogens and in promoting weight gain. As such EGF can be used to treat intestinal infections and increase animal production for example in the agriculture or aquaculture industry. EGF is also useful in increasing the intestinal absorption of immunoglobulins. Inhibition of the epidermal growth factor signalling cascade may be used to prevent uptake of toxic or adverse compounds or to promote weight loss. Therefore, the use of an agent that inhibits the activity of epidermal growth factor to decrease the absorption of substance or decrease weight gain is also described.

Inventor: SCHERER PHILIP G
IPC: B65H18/16
Filed: 1997-12-30
Abstract: A system and method for controlling vibration of an axially rotatable mandrel useable for winding sheet material including stretch film thereabout. The system includes first, second and third roller members rotatably contactable with the mandrel and sheet material wound thereabout. The roller members are arranged about the mandrel axis so that the mandrel and any sheet material wound about the mandrel is supportably captured between the roller members to prevent or at least substantially reduce vibration of the rotatable mandrel. At least the first and second roller members are biasable toward the mandrel with pneumatic pressure from corresponding air over oil cylinders, and the first and second roller members are movable away from the mandrel against hydraulic resistance from the corresponding air over oil cylinders to accommodate sheet material wound increasingly about the mandrel. In one configuration, first and second mandrels are rotatably coupled to a rotatable turret that alternately positions the mandrels relative to a power driven lay-on roll, wherein each mandrel has at least one corresponding set of first and second roller members which cooperate with the lay-on roll to prevent vibration of the rotating mandrel.

Title: Absorbent paper products
Inventor: HERMAN JEFFREY B
IPC: D21H27/02
Filed: 1996-12-20
Abstract: An improved absorbent consumer paper product such as toilet tissue and a method and system for making such a product involves an improved drying fabric that forms an aesthetically pleasing and functionally superior pattern on the paper web before creping. The drying fabric is characterized by a plurality of shute threads extending substantially parallel to each other in a cross direction of the drying fabric; and a plurality of warp threads extending substantially parallel to each other in a machine direction of the drying fabric. The shute and warp threads are woven together so as to define a number of relatively long warp knuckles at locations where one of said warp threads crosses over at least four of the shute threads. The long warp knuckles are positioned in a shed pattern so as to form (a) a first axis to bulky ridges that are defined by long warp knuckles which are positioned next to each other on adjacent warp threads, the first axis being disposed at a first angle with respect to the cross direction of the drying fabric that is substantially within the range of greater than 68 degrees but less than 90 degrees; and (b) a second axis formed by eah of the long warp knuckles with other, overlapping long warp knuckles on nearby, but not immediately adjacent, warp threads, the second axis forming a second angle with respect to the cross direction of the drying fabric and being less than about 28 degrees. This pattern improves crepeability of the web and forms a bulky, absorbent, soft tissue product characterized by parallel, continuous low density ridges of substantially uncompressed fibers.

Title: Time-duplex wireless telephone with improved hearing-aid compatibility
Inventor: DENT PAUL W
IPC: H04B1/40
Filed: 1997-01-24
Abstract: A time-duplex wireless telephone for reducing magnetic coupling between the wireless telephone and a hearing aid to prevent hum pick-up in the hearing aid. The wireless telephone includes a battery, a radio circuit, and a humbucking coil. The radio circuit is connected to the battery and has a transmit mode where transmit signals are transmitted and a receive mode where received signals are received. The radio circuit intermittently is switched between the transmit mode and the receive mode. The radio circuit generates a transmission magnetic field when the radio circuit is transmitting transmit signals. A  humbucking coil is connected in the radio circuit to generate a cancellation magnetic field that is directly proportional to the transmission magnetic field and in antiphase with the transmission magnetic field. The cancellation magnetic field at least partially cancels the transmission magnetic field and reduces magnetic coupling between the wireless telephone and a hearing aid used in conjunction with the wireless telephone.
