Title: Fuel burner control system with hot surface ignition
IPC: F23D14/00
Filed: 1989-11-22
Abstract: ABSTRACT OF THE DISCLOSURE A gas burner control system includes an electrical resistance igniter, gas valve means, and a microcomputer and related circuitry. The microcomputer and related circuitry control energizing of the igniter in such a manner so that the igniter, after successive ignition attempts, will eventually, in response to a learning routine, be heated to a desired ignition temperature.

Patent CA-2083256-A1 (CA)
Inventor: BARREIRO ARMANDO
IPC: A61H15/00
Filed: 1992-03-27
Abstract: A method for applying a mechanical massage using a massage mechanism unit having a pair of spaced parallel arm members (33) and a massaging wheel (351 or 352) rotatably supported on one end of each of the arm members (33). The massaging wheels (351 or 352) are positioned on the back of the user on opposite sides of the spinal column. The massaging wheels (351 or 352) are then simultaneously moved and turned in the same direction from left to right and right to left while moving back and forth along sinusoidal paths on two sides of the spinal column. The pressure exerted by one of the massaging wheels (351 or 352) on the back is reduced by moving the massaging wheel (351) away from the back as the massaging wheel (351) moves closer to the spinal column. The pressure exerted by the other massaging wheel (352) is increased by moving the massaging wheel (352) toward the back as the massaging wheel (352) moves away from the spinal column.

Patent CA-2098860-A1 (CA)
Title: Method and Apparatus for Detecting the Position of Liquid-Liquid Interfaces
Inventor: MCHARDY JOHN
IPC: G01F23/00
Filed: 1993-06-21
Abstract: Precise information about the position of a liquid-liquid interface (28, 32) is often important for the control and automation of molten metal refining processes.   For example, in an electrolytic process for removing magnesium from molten aluminum, knowledge of the vertical position of an interface (32) between the electrolyte and the magnesium and an interface (28) between the electrolyte and the aluminum facilitates the automatic removal of the purified metals. Differences in surface tension in the fluid layers of a molten electrolytic  salt  (30)  and  a  molten metal  (29)  produce different pressures as bubbles (57) evolved from vertically displaced tips (52) of tubes (34, 36) press against the liquid layers on either side of their interfaces (28, 32).  These different pressures are detected by a differential pressure transducer  (42)  to  limit  the  amount of  purified molten aluminum from molten aluminum-magnesium scrap, when drawn through a port (26) in a reaction furnace (10) without risk of also  contaminating  the  purified  aluminum  with  the electrolyte (30) above the interface.

Title: Method for quick charging of rechargable batteries
Inventor: AL-ABASSY ISSAM
IPC: H01M10/44
Filed: 1992-05-30
Abstract: A device for quick charging of batteries, whereby the charging current of the battery is directed in constant current impulses. Several charging current strengths of varying strengths are brought into effect, depending on the respective charging condition of the battery, by clock impulses. Assigned to each charging current strength is a battery-specific zone in the electrochemical voltage gradient U=f(t), whereby the individual zones are indicated by voltage set values. The voltage zone assigned to each charging current strength is so chosen that in passing through this zone, no heating or gassing occurs. Thereby, use is made of the fact that the battery at the beginning of the charging can accept a very high current. The charging condition of the battery is measured in each impulse pause, stored and compared with the voltage set value. Where there is a variance, the set-current value assigned to the zone is correspondingly adjusted.

Abstract: The  surge  arrester  contains  two  connection fittings (1, 2) which are spaced apart from one another along  an  axis  and  between  which  at least  one cylindrical  varistor  element  (7)  is  arranged.  The connection  fittings  (1,  2)  and  the  at  least  one varistor  element  (7)  are  clamped with  one  another, accompanied by the formation of contact force, to form a  mechanically  stable  active  part  of  the  surge arrester.  The  active  part  is  surrounded  by  a  cast housing (12) made from insulating material.        The clamping of the active part is achieved by at   least   two   loops   (5)   respectively   acting independently of one another on the connection fittings (1, 2). The loops (5) are arranged at a distance from the at least one varistor element (7). The connection fittings (1, 2) contain bearing areas which correspond respectively to the number of the loops  (5)  and are distributed uniformly about the axis azimuthally and on which a loop end is respectively supported. Despite its simple design, the surge arrester has good mechanical and electrical characteristics and can be produced in a particularly cost-effective way.

Inventor: KNODEL ART
IPC: F24D15/02
Filed: 1994-04-11
Abstract: Conventional methods of providing heating to buildings under construction typi-cally comprises the use of portable propane powered forced air heaters. Such conven-tional systems utilize a fan motor to direct the exhaust products of combustion to the worksite. The exhaust fumes from such heaters may cause headaches and/or nausea in workers exposed to the fumes for extended periods. In addition the open flame aspect associated with such heaters make their use in potentially explosive environments im-possible. A more desirable device makes use of an efficient heat exchanger system to produce a stream of substantially odor free heated air. The device comprises a heat exchanger constructed from a pair of back to back ribbed cones with an axially dis-posed exhaust plenum at one end and a means for mounting a conventional burner, axially disposed, at the other end. The heat exchanger is enshrouded in a generally spherical shaped outer enclosure and outside air fan forced into the rear of the shroud and over the heat exchanger surface. The outside air, thus heated, is directed through the front of the shroud and may be utilized directly or conveyed to a remote site by conventional ducting. The heated air thus produced is free from exhaust contaminants and substantially odor free. The exhaust gases may, in turn, be used as a source of radiated heat prior to venting to the atmosphere. The nature of the device is such that there is no open flame and the device may thus be rendered suitable for use in an explosive environment with relatively little modification.
