Patent CA-2159496-A1 (CA)
Inventor: KAIMOTO TAKASHI
IPC: H05B3/14
Filed: 1995-01-27
Abstract: A flat PTC heater according to the present invention is formed by bonding one or a plurality of thin plate type PTC ceramic members (1) on a surface of each of which a pair of electrodes are provided to an insulator (3). When more than one thin plate type PTC ceramic members (1) are provided, electrodes (2) of the same polarity are electrically parallel-connected by lead wires (6). The occurrence of warpage, leakage and short-circuiting is prevented by forming a layer (4) of an elastic insulating material on an electrode-carrying surface.  The occurence of warpage after printing and firing operations is prevented by setting the thickness of the thin plate type PTC ceramic member to not less than 0.5 mm. In the resistance value regulating method according to the present invention, in which the resistance between the electrodes (2) on each PTC ceramic member (1) on the flat PTC heater is regulated, a conductive passage on an electrode pattern is cut off at an intermediate portion thereof, or predetermined portions (8) at which a conductive passage has been cut off in advance are connected by soldering, whereby the resistance between the PTC  ceramic members is regulated. In a thin PTC plate unit according to the present invention, a PTC thermistor element having a pair of electrodes on one surface thereof is fixed directly and closely on an insulating board, and an insulating board is pasted on the other surface of the thermistor element.

Title: Method for prevention of scale formation in aqueous systems
Inventor: KING KATHLEEN JOAN
IPC: C02F5/12
Filed: 1995-11-08
Abstract: A process for stabilizing aqueous systems containing scale-forming salts by adding to such systems an effective amount of selected low molecular weight water-soluble polymers containing from 30 to 60 weight percent unsaturated sulfonic acid units, from 35 to 65 weight percent carboxylic acid units and optionally up to 10 weight percent of one or more units selected from non-ionizable monomers, is provided.

Patent CA-2163955-A1 (CA)
Title: Humidification device
Inventor: DIDOMENICO NICHOLAS F
IPC: F24F6/04
Filed: 1995-11-28
Abstract: The humidification device includes a tube formed of gas permeable material connected to a water source by a tube formed of material that is substantially impermeable to water. The gas permeable tube permits water to evaporate through the tube wall and is thus an evaporation tube. The evaporation tube is disposed in a chamber that is to be humidified. As water evaporates from the evaporation tube, the humidity in the chamber builds up to a maximum level. At the maximum humidity level evaporation of water from the evaporation tube ceases. When the humidity level in the chamber drops below the maximum level, evaporation of water from the evaporation tube resumes to restore the humidity in the chamber to its maximum level. Water flow from the water source replaces evaporated water from the evaporation tube. The humidification device is thus self-regulating and does not require any water flow regulating devices. One or more water flow tubes can be connected to the evaporation tube from a water source.

Title: Training device for maximising athletic motion
Inventor: TAYLOR JACK
IPC: A63B15/00
Filed: 1996-03-01
Abstract: A training device provides an indication of when the maximum power is exerted in an athletic motion. The training device utilises the magnetic attraction of a steel ball to a magnet. An applied or centrifugal force can overcome the attraction of a steel ball for a magnet and the point at which this attraction is overcome is signalled by a noise or light emission. In operation the training device is placed on an appendage, or placed or incorporated into a piece of sports equipment, for instance, a golf club, and the point at which the magnetic force is overcome is, by adjustment, correlated to the point of maximum power of the athletic motion.
