Patent CA-2002172-A1 (CA)
Title: Method for bauxite treatment
Inventor: BROWN NEIL
IPC: C01F7/062
Filed: 1989-11-03
Abstract: ABSTRACT OF THE DISCLOSURE        A process for lowering the concentration of organic carbon substances in a caustic aluminate liquor of the Bayer process for the production of alumina from bauxite.  The method comprises thermally treating bauxite prior to dissolution in the caustic aluminate liquor to destroy a portion of the organic content, with the thermal treatment substantially removing that part of the organic carbon content responsible for the formation of sodium oxalate.  During the treatment, any gibbsite (aluminum trihydroxide) present in the bauxite is converted to a form which has a higher solubility in caustic aluminate liquor than gibbsite.  In addition, the iron oxides present convert to a more readily settleable form, improving the overall processability of the bauxite.  Utilizing this process allows bauxites with widely varying amounts of organic carbon to be accommodated in the Bayer process without affecting processability or plant operations.
Patent CA-2003166-A1 (CA)
Inventor: GUERRERI CARL N
IPC: F42D1/05
Filed: 1989-11-16
Abstract: ABSTRACT OF THE DISCLOSURE     Explosive charges are detonated by remote control in environments having high levels of extraneous electric and electromagnetic energy by providing a separate control unit for each explosive charge.  The control unit accepts coded commands radio transmitted from a command unit and, if those commands meet with pre-set criteria, the control unit detonates the charge.   Each control unit is connected to its respective explosive  charge by  electrical  or  optical  conductors providing sufficient separation as to allow the control unit to survive detonation of the charge without damage.

IPC: F02B3/06
Filed: 1991-03-15
Abstract: ABSTRACT           A method  to  heat  a  diesel  fuel  to  a temperature within the range of 95 to 115°F,   and preferably 105°F,  and then feeding the fuel at this temperature  to  fuel  diesel  injectors  of  a  diesel motor,   in order  to maximize  the efficiency of a diesel motor.   A thermostatically controlled, diesel system heated with  an  automotive  electrical power source to be mounted adjacent a diesel pump of a diesel motor is also described.   It comprises a fuel reservoir having an inlet at one end and an outlet at the other end.   The inlets and outlets are joined in the reservoir by a heating coil,  with the reservoir being filled with a heating oil.    Heating elements for  heating  the  ambient  oil  are  provided  in  the reservoir.  A diesel fuel entering through the inlet is  gradually  heated  by  the  ambiant  oil  in  the reservoir in order to produce a flow of heated fuel through the outlet.    The operation of the heating elements  is  controlled  by  a temperature  sensing device provided in the outlet,  and thus close to the diesel pump.   The heating elements are operatively connected to the battery via a switch and a relay. The  relay  itself  is  operatively  connected  to  a control module to be actuated by a signal derived from the temperature sensing device, such that the temperature sensing device via the control module is targeted to open the  switch when the fuel  at the outlet reaches a temperature in excess of 105°F +/-10°F and to close the switch when the temperature is at a temperature within 105°F +/- 10.

Title: Windtrap for power development
Inventor: WHELAN MATTHEW P
IPC: F03D9/34
Filed: 1991-07-10
Abstract: ABSTRACT The several methods used to develop windpower have the disadvantage of losing most of the wind's force in their operation, example, where vanes are used slippage is a big problem and in the vertical mast type of machines such as the "Darrieus" and "Savonius" a lot of power is lost by resistance on the return side of the mast. This invention, the "Windtrap", holds all the wind within the dimensional area of each unit when on the drive or power side and is so designed that it closes and comes edge on to the wind on the return side of the mast giving minimum resistance.
