Title: Method and device for generating a laser beam
Inventor: VAN GOOR FREDERIK
IPC: H01S3/0971
Filed: 1996-02-01
Abstract: Described are a method for generating a laser beam and a laser device for   the method. In a first step gas is ionised by means of X-rays. In a second step the electron density is increased by means of a pre-discharge. In a third step the main discharge takes place. Between the second and third steps, am electron redistribution occurs. According to the invention, the electron redistribution rate and/or the time delay between the pre-discharge and the main discharge are adjustable and controllable in relation to each other, for achieving a particular desired beam profile, such as a uniform profile. Because that delay is preferably set by varying one or more process parameters, an important advantage is achieved in that it is possible with one and the same laser device to modify the beam profile in a simple and flexible manner even during the operation of the laser device.

Title: Oscillatory motion device for drill press
Inventor: BOWMAN DOUGLAS ALLEN
IPC: B24B41/04
Filed: 1996-10-22
Abstract: A drill press has a drive motor with output shaft that drives a chuck through a rotatable and vertically displaceable quill and a first drive coupling which includes a pair of pulleys, such as cone pulleys, and a belt extended between the cone pulleys. A rotary power take-off in the form of an additional pair of pulleys and a drive belt extracts rotary power from the drive coupling between the motor and the chuck and transfers it to an oscillatory motion device. The device includes a worm and worm gear and an eccentrically mounted arm which convert rotary motion from the rotary power take-off into a reciprocating linear motion. A lever is pivotally mounted to the device with one end engaged with the quill and a remaining, opposing end coupled with the arm.      Reciprocation of the arm causes reciprocation of the lever which causes reciprocation of the quill, chuck and any tool held in the chuck. The arm is releasably engaged with and is coupled with the lever through a detent block.

Title: Method and system in a fluid heating apparatus for efficiently controlling combustion
Inventor: ADAMS CHARLES L
IPC: F23N1/08
Filed: 1996-11-25
Abstract: In a fluid heating apparatus having a fluid tank, a combustion chamber communicating with the fluid tank for heat exchange, and a combustible fluid delivery system coupled to the combustion chamber, a plurality of valves are individually configured in either an off-state or an on-state for delivering combustible fluid to the combustion chamber. Depending on the configuration of the multiple valves, the rate at which combustible fluid is supplied to the combustion chamber may be varied in response to a heat demand signal. Individual valve signals are generated for each of the multiple valves in response to the heat demand signal to place the multiple valves in a configuration to supply combustible fluid at predetermined rates. The demand signal is calculated in response to reading temperature at an inlet temperature probe and an outlet temperature probe, wherein the outlet temperature probe is located nearer a fluid outlet from the fluid tank than is the inlet temperature probe. The heat demand signal may also be a function of the excess of a set point temperature over a temperature measured by the outlet temperature probe. An airblower may also be coupled to the combustion chamber and operated in a plurality of modes for supplying air at a plurality of rates in response to the heat demand signal. The rates of air supply provided by the air blower are selected to supply air at a stoichiometric rates in relation to the fuel supply rates provided by various configurations of the valves in the combustible fluid delivery system.

Patent CA-2204689-A1 (CA)
Title: Process and device for operating a gas burner
Inventor: SCHWEDLER NORBERT
IPC: F23N1/02
Filed: 1997-05-07
Abstract: In a process for operating a gas blower burner, a control circuit detects an ionization signal Ui derived from an ionization electrode, and it adjusts the gas-to-air ratio to a lambda set point >1, to which a set point Uis of the ionization signal corresponds. To guarantee low-emission combustion in different operating states, a range of control of the ionization signal Ui is set, whose upper limit value Uio is smaller than the maximum of the ionization signal Ui, and whose lower limit value Uiu is above the value that guarantees low-emission operation. A switch-off signal is generated for the burner if the ionization signal Ui leaves the permissible range of control RB for longer than a preset period of time. If the value is lower than the lower limit value Uiu of the ionization signal Ui and when the value is lower than the set point Uis at a lambda value < 1, the control circuit increases the gas volume flow to an end value, and another switch-off signal is generated for the burner when this end value is reached.

Title: Integrated electronic/hydraulic control for industrial electric vehicles
Inventor: GADBOIS PIERRE C
IPC: B66F9/20
Filed: 1997-07-18
Abstract: A controller system for an electric lift truck that controls a traction motor (86) and a hydraulic pump motor (12) is disclosed. The speed of rotation of both motors (86, 12) is controlled by a pulse width modulated current supplied from a battery source (84) by the controller (80) in direct response to a demand communicated to the controller (80) through an interface (50) manipulated by an operator. A pump (13) driven by the pump motor (12) supplies pressurised hydraulic fluid to a lift mechanism (90) and a power assisted steering unit (17). A priority valve (14) ensures that the pressurized hydraulic fluid first satisfies the power assisted steering unit (17) before being used for other hydraulic functions. A joystick (52) with function switches (56, 58, 60 and 62) is provided so that the operator steers with one hand while controlling truck propulsion and all functions of the lift mechanism (90) with the other hand. The combination of direct control of the pump motor (12) speed and on-demand pressure switch (16) enables a fully proportional control of the hydraulic system. The system provides a compact structure with minimal cabling and ensures that the hydraulic system operates with energy efficiency and minimal wear.

Title: Automatic switching-off structure for protecting electronic device from burning
Inventor: JE HUNG
IPC: H01H37/76
Filed: 1997-09-23
Abstract: An electronic device integrally formed with an automatic switching-off structure for protecting the device from overheating. At least one conducting lead of the electronic device is mechanically and electrically connected to its corresponding electrode by a solder column having desired melting point, with an appropriate spacing being kept between the conducting lead and the electrode. The coating layer of the electronic device is formed by a material such as epoxy resin which will soften and release a gaseous substance when heated to a temperature near its ignition point. When the temperature of the device exceeds the melting point of the solder, the solder column melts to break the electrical circuit and prevent overheating of the device.
