Title: Process for autogenous flame cutting with liquid oxygen
Inventor: GROHMANN PAUL
IPC: B23K7/10
Filed: 1993-10-05
Abstract: PROCESS FOR AUTOGENOUS FLAME CUTTING WITH LIQUID OXYGEN     Abstract of the Disclosure In autogenous flame cutting with liquid oxygen, the oxygen is cooled off by a cryogenic medium, preferably nitrogen, to such an extent that the liquid oxygen jet which strikes the cutting site has a temperature that lies below the boiling temperature of oxygen at ambient pressure. This requires the installation and use of two different cryogenic media.  In order to avoid this complex arrange-ment, the cooling off is effectuated by liquid oxygen whose pressure is lower than the pressure of the liquid oxygen used for the flame cutting.  The pressure is preferably below that of the ambient pressure.

Title: Removal of contaminants from water
Inventor: GILLHAM ROBERT W
IPC: C02F1/28
Filed: 1992-04-24
Abstract: 2108981 9219545 PCTABS00017 In a water treatment plant, contaminants such as CTC are adsorbed onto activated carbon: the contaminants are removed by mixing granules of a metal, e.g. iron fillings, into the contaminant-laden activated carbon. The presence of the metal leads to the chemical breakdown of the contaminant. The cleansed activated carbon may be re-used, with or without separating the iron from the mixture.

Title: Underwater detection system
Inventor: NISHIMORI YASUSHI
IPC: G01S3/805
Filed: 1993-02-04
Abstract: The  present  invention  is  directed  to  provide  an underwater detection system which can determine frequency components contained in echoes arriving from all azimuthal directions at high speed and enhance target discriminating capabilities by presenting such frequency components.           The  underwater detection system rotates  a  pair  of ultrasonic receiving beams having a fixed phase angle difference, measures phase differences between two signals picked up by both ultrasonic receiving beams, determines carrier frequencies contained in target echoes from the phase differences, derives magnitudes and directions of moving velocities of targets from the carrier frequencies, and displays  such target  data in different  colors.          Furthermore, it provides such information as over-the-ground velocities of targets themselves upon compensating target velocity data with ship velocity data.

Patent CA-2131216-A1 (CA)
Inventor: DUVALL LANNY R
IPC: F26B7/00
Filed: 1994-08-31
Abstract: A method of removing solvents from a paste such as a detergent paste, includes introducing a heated paste into a channel of a dryer under pressure selected so as to avoid flashing of any of the components of the paste.  At the inlet of the channel, the pressure is dropped, resulting in the flashing of selected components of the paste.  As the paste advances through the channel heat is applied to the paste.   Vapor liberated during the flashing acts as a motive force to convey the increasingly viscous paste along the channel.  The resulting concentrate is collected at an outlet of the channel.

Title: Personal computer with keyboard and auxiliary device emulation
Inventor: HESS RANDALL L
IPC: G06F3/038
Filed: 1994-08-31
Abstract: PERSONAL COMPUTER WITH KEYBOARD AND AUXILIARY DEVICE EMULATION            ABSTRACT      A computer system which provides emulation routines that cause a keyboard or mouse to appear present to the system software even when the devices are not physically installed.  On system start up, this allows installation of appropriate device drivers by the operating system.  If a keyboard or mouse is later installed, the emulation responses are discontinued, and a keyboard and mouse operate normally.  When the system is placed in a standby state, the keyboard and mouse connectors are totally powered down.  Before this power down, the BIOS routines save the configuration state of the keyboard and mouse as recorded by the emulation routines, which have been tracking commands sent to those devices even when those devices are operating. When power is reenabled to the keyboard and mouse connectors, the configuration of those devices is restored from that saved configuration data. Further, the system detects whether a keyboard or mouse is installed on a particular connector, and appropriately maps the keyboard and auxiliary ports to correspond to that connector.

Patent CA-2151756-A1 (CA)
Title: Electric machine controller
Inventor: TURNER MICHAEL JAMES
IPC: H02P25/08
Filed: 1995-06-14
Abstract: A controller for a switched electric machine, especially a switched reluctance motor,  takes timing information from a rotor position transducer to generate a switch-off output at a point near maximum phase inductance in a phase inductance cycle.  A switch-on signal is generated after a delay but still within the phase  inductance cycle.  A simple form of single-pulse control is thereby achieved.  A comparator is also provided which monitors phase winding current.  A pulse generator is actuated by the  comparator  when  the  winding current  exceeds  a reference level and is used to control the motor in a chopping mode at  low speeds and  is disabled by the comparator at higher speeds when the single-pulse control is used.
