Title: Apparatus and process for extracting oil  or bitumen from tar sands
Inventor: HARDING DUKECAL J
IPC: C10G1/04
Filed: 1978-05-30
Granted: 1982-06-22
Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an apparatus and process for extracting bitumen from mineral particles such as sand.          The invention avoids many of the problems of the conventional hot water or solvent extraction processes by using an abrading process to remove the bitumen or oil from sand particles, using cool water and little solvent. The abrading process involves agitating a pulp of tar sand and water, preferably with some small amount of diluent, and then moving this around an annular space at a speed low enough to allow settling of clean sand to form a sand bed in contact with the moving pulp, the speed being high enough to prevent settling of bitumen coated sand particles, so that the bitumen is abraded from the sand particles and rises in the pulp.  Fines and clay which are removed with the water and bitumen can be separated from the water, after removal of the bitumen, to give a sludge suitable for mixing with the clean sand prior to disposal.

Abstract: ABSTRACT OF THE DISCLOSURE      A liquid level indicator device for providing a visual indication of the level of liquid within a movably mounted tank, disclosed as a dishwasher door mounted rinse-aid liquid dispenser tank, in which the dispenser tank is alternately positioned in either the vertical or horizontal position by the opening and closing of the door.  The liquid level indicator includes a tank wall mounted indicator housing defining a viewing chamber into which is passed a small quantity of liquid when the tank is in the vertical or door closed position if the level is above a predetermined level and a portion of which liquid is retained within the viewing chamber as the tank moves to the door open position to enable viewing of the liquid through a sight window provided.  The capture and retention of liquid within the viewing chamber is carried out by means of a catch cup mounted beneath the sight window, with clearance spaces allowing entrance of liquid when the dispenser tank is in the vertical position, but the orientation of the catch cup preventing escape of the liquid as the dispenser tank is moved to the horizontal position and the liquid retreats from the tank wall to which the indicator housing is mounted.  The vividness of the visual impression created by the presence of the liquid in the viewing chamber is enhanced by the use of high contrast treatment of the bottom surface of the catch cup within which the liquid is retained.

Abstract: VARIABLE FREQUENCY OSCILLATOR WITH STABLE            CENTER FREQUENCY            Abstract Of The Disclosure Disclosed is a variable frequency oscillator system having a very stable center frequency and adjustable over a wide range of frequency excursions.  A pair of variable frequency oscillators (VFO) are fabricated on the same integrated circuit chip so that corresponding components have substantially identical characteristics.  The first VFO and a highly stable crystal oscillator provide comparable frequency output signals to a phase locked loop which provides as its output a correction signal (voltage or current) to lock the first VFO to the crystal oscillator frequency.  The frequency of the second VFO in turn will be essentially the same as that of the first because of simi-larities in components and operating conditions as well as sharing of the correction signal between the two VFO's.  The output of the second VFO provides the local clock signal and can be varied further by a second correction signal.  In one embodiment, the second correction signal is provided by a second phase locked loop.

Abstract: ABSTRACT          An arrangement for the sterilizing of a packing material web with the object of removing any contaminations and bacteria present on the material web before the web is converted to individual packing containers. The sterilization takes place with the help of chemical sterilizing agents, e.g. hydrogen peroxide, in combination with the mechanical treatment of the packing material web. The arrangement consists of a rotary brush located in a container which via an opening in the con-tainer treats the side of the passing material web which thereafter is to form the inside in the packing container. At the same time a liquid sterilizing agent introduced into the container is flung with the help of the brush against the surface of the packing material web. The bulk of the contaminated sterilizing agent is separated thereafter together with the contaminations and bacteria removed from the material web, in that owing to the rotation of the brush it is flung out through another opening in the container wall, which opening collects the sterilizing agent and leads the same away for purification and re-use. The arrangement is particularly suitable for high-capacity packing machines of the aseptic type, wherein a relatively rapidly moving packing material web is to be cleaned and sterilized.
