Patent CA-2131213-A1 (CA)
Title: Battery pack with minimum hard wiring connection for portable computer
Inventor: ILLINGWORTH PATRICK V
IPC: G06F1/16
Filed: 1994-08-31
Abstract: BATTERY PACK WITH MINIMUM HARD WIRING CONNECTION FOR PORTABLE COMPUTER            ABSTRACT      A battery pack for a portable or notebook computer which substantially eliminates hard wiring components including a generally rectangular housing having an opening in the bottom.  The opening in the bottom receives a support chassis which mounts a series of electrical contact points for interfacing with the main computer housing.  The support chassis mounts a printed circuit board which receives the electrical contact points for electrical connection to the various components of the printed circuit board such that electrical connection is made between the array of batteries and the main computer housing utilizing a series of electrical surface contact points rather than hard wiring, which preserves space and reduces manufacturing costs.

Filed: 1993-03-26
Abstract: When producing a fat product containing milk fat with a reduced fat content cream is concentrated to a cream product with a fat content of at least 75 % in a centrifugal separator. The cream product is mixed with vegetable oil in an amount of 0-50 % of the total amount of fat in the fat phase which is obtained consisting of cream product and vegetable oil. The fat phase is mixed with a desired amount pasteurized water containing stabilizing means, preferably gelatin, salt and aroma substances. The temperature is kept between 50-80 ·C during the last mentioned mixing operation.  The obtained mixture is cooled and worked such that phase reversal takes place. The obtained end product consists of a stable water-in-oil-emulsion. The product has a fat content of 25-60 % and contains only emulsifiers occurring originally in the cream. The casein content of the product is below 2 %.

Title: A metering device for fluids
Inventor: KELLER WILHELM A
IPC: G01F11/20
Filed: 1994-09-30
Abstract: The metering device comprises a housing, defining at least one inlet for the material to be metered and at least one outlet for that material, and at least one rotatable ball driven by a shaft, said ball having a transverse bore containing a shuttling ball moving linearly in said bore between two seats and seals against the one or the other seat. The rotatable ball is captured between the seats and seals under pressure against the outlet seat. Such a metering device allows an exact metering, in shot or rapid shot resulting in near continuous flow form, has great simplicity of construction with few working parts such as that it may easily be placed at the dispensing end of a pressure transfer system for liquids and gases and acts as shut off valve between metering use such that it prevents stalled hydrostatic fluid pressure behind the metering device from causing a flow surge ahead of the metering device at start up.

Title: Method of observer-based control of permanent-magnet synchronous motors
Inventor: TAYLOR DAVID G
IPC: H02K29/14
Filed: 1993-11-04
Abstract: 2148466 9411945 PCTABScor01 A method of estimating and controlling rotor position and velocity for a multi-phase brushless permanent-magnet motor (12) by measuring only the stator phase 5 currents (24) at a high sampling rate. Measurements of the stator phase currents (24) are used to obtain estimates of rotor position and velocity. In turn, these estimates are used to determine an amount of voltage to apply to each stator phase so as to obtain a desired regulation of rotor position or velocity, or to command rotor position or velocity to follow a desired trajectory. Estimation and control of rotor position and velocity are implemented on the order of several times per millisecond by an approximate discretization technique.  Furthermore, rotor position is observable at zero rotor speed.
Patent CA-2148902-A1 (CA)
Title: A writing implement using liquid ink, in particular a solvent-based ink
Inventor: CHAVATTE PHILIPPE
IPC: G01D15/16
Filed: 1995-05-08
Abstract: The writing implement using liquid ink is constituted by: a) a body whose rear portion constitutes a reservoir for the ink; b) a transfer rod whose rear end opens out into the reservoir and whose front end projects out from said body and forms a writing tip; and c) a buffer reservoir in contact with the transfer rod.      The surface tension of the ink lies in the range 21 mN/m to 25 mN/m, and is intended for use on non-absorbent media made of metal or of plastic. The surface tension of the material constituting the buffer reservoir is less than that of the ink by a determined difference which is preferably equal to or less than 4 mN/m, thereby enabling the buffer reservoir to absorb and give back any excess ink coming from the transfer rod by capillarity in the event of variation in the pressure inside the reservoir.      The buffer reservoir may be made of a material whose surface tension has been lowered by depositing an agent whose surface tension is less than that of the ink while lying within the determined difference, e.g. fluorine, polysiloxane, or a fluorine-containing resin.
