Patent CA-1102626-A (CA)
Inventor: DALLEN JOHN A
Filed: 1978-11-02
Granted: 1981-06-09
Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a portable waste disposal system that is designed primarily for use in marine craft, mobile homes, campers or the like. The system comprises a macerator until for converting excrement to a liquified effluent, and an incinerator unit for incinerating the effluent. The macerator unit comprises a holding tank which receives the waste material from a toilet.  When the level of the excrement within the holding tank reaches a predetermined level, and maintains that level for a predetermined period of time, the system is activated and the excrement from the holding tank is macerated by a macerator and provided to a feed compartment.  A circulation pump then pumps the macerated effluent from the feed compartment through a circulation line to the incineration unit.      The incineration unit comprises a combustion chamber and an additional feed pump which draws effluent from the circulation line and feeds the effluent into the combustion chamber.  A crucible is disposed within the combustion chamber for receiving the effluent fed therein. A burner is provided which introduces a high temperature flame into the combustion chamber to incinerate the effluent in the crucible.  The crucible is elevated from the floor and spaced from the walls of the combustion chamber so that the flame from the burner fills the entire combustion chamber and heats the crucible on all sides.  The effluent within the crucible is incinerated until all of the liquid is vaporized and the remaining solid waste material is reduced to a fine ash.     The fuel for the burner is reguinted by a pair of fuel valves, one of which is cycled to maintain the temperature of the exhaust gases from the combustion chamber within predetermined limits.  In addition, the entire incineration operation is conducted at a sufficiently elevated temperature so that no offensive odor is created.  A pot rotator motor is also provided for rotating the crucible after the incineration cycle is complete to dump the remaining ash material to the floor of the com-bustion chamber.  A convenient ash removal duct is provided at the rear of the incineration unit for removing accumulated waste material.           The incinerator unit also includes a novel cooling system for dissipating the heat from the combustion chamber, and cooling various critical components to insure the proper operation of the system.  The entire system is operated under the control of a solid state control circuit which continuously monitors the system to insure that it is operating within certain critical parameters.  As a safety precaution, if various positive checks are not confirmed, the control unit automati-cally shuts down the system, thus eliminating the possibility of an accidental fire.

Abstract: ABSTRACT OF THE DISCLOSURE      A fluid filter is disclosed which separates gas from liquid and vents the separated gas from the filter. The filter includes a vented housing through which the fluid stream passes.  Liquid-wetting filter means carried in the housing in the path of the fluid stream permits the passage of liquid only.  Gas separated from the fluid is vented through vent opening means which is covered by a liquid-repellent filter to permit the passage of gas only.  An automatic, pressure sensitive control means may be used to seal the vent opening means against the entry of ambient air but to automatically release separated gas from the filter.  The liquid-repellent filter may be secured to the housing by a mechanical bond between the housing and a fibrous backing carried by the filter, or a continuous band of medical grade tape may be used to attach the filter to the housing.

Abstract: ABSTRACT OF THE DISCLOSURE            An ionization fire-signal device is provided which is compact in construction so that it has a small axial height. The housing for the device includes an axial extending outer wall and a transversely extending front wall to form a cup shaped housing.  An insulator, including an axially extending circular wall which forms an enclosure, is positioned inside the housing and cooperates with the housing to form a measuring chamber.  The axial dimension of the circular insulator wall and outer housing wall are approximately equal.  In addition, a reference chamber is formed between the circular wall of the insulator and the outer wall of the housing such that the reference chamber is arranged transversely adjacent to the measuring chamber.  A radiation source for ionizing the measuring chamber and reference chamber is also provided.  An electrical alarm signal circuit is also disposed between the circular insulator wall and the outer housing wall and is electrically connected to two electrodes in the measuring chamber and two electrodes in the reference chamber.

The master cylinder is shown installed in an X-split vehicle brake system.  The master cylinder assembly includes a pressure failure warning device.  The arrangement pro-vides a minimum number of leak points, permits the master cylinder and the modular proportioners to be built and tested separately, and enhances serviceability since the modular proportioners can be separately replaced without removing the master cylinder.  It also permits the master cylinder to be of a universal type with modular propor-tioners of various proportioning characteristics used in accordance with the particular vehicle application.

Abstract: ABSTRACT OF THE DISCLOSURE       Certain windings in a transformer are subjected to radially inwardly-directed forces while being short-circuited.  If such a winding is not sufficiently stable itself, particularly with respect to tape windings, or does not have sufficient support radially outwardly or inwardly, it will buckle or break.  To prevent such an occurrence, it is possible to arrange an outward support around the winding by completely or partly filling up the space between the winding, which is subjected to buckling stress, and a second winding positioned outside the first winding.  Additionally, there is required an inner supporting cylinder, which is preferably made of metal, so that it can be made relatively thin.

Air deflector means corresponding in number to the number of grinding rolls are mounted within the separator body so as to be located in juxtaposed relation to the inner surface of the separator body and so that an air deflector means is interposed between each pair of adjacent grinding rolls.  An air supply means suitably formed in the separator body is associated with each of the air deflector means.  Each of the air supply means is operable to supply air from an external source thereof therethrough to the interior of the separator body.  A material supply means operable for supplying the material to be ground in the bowl mill is suitably formed in the separator body.  Each of the air deflector means is operable to concomitantly perform both the function of effecting a leveling of material disposed on the rotating grinding table so as to present a uniform layer of material to the grinding roll located immediately downstream thereof and the function of encompass-ing all the air flow provided by the air supply means associated therewith for purposes of effecting the subsequent deflection thereby of this air flow over the rotating grinding table.

Abstract: ABSTRACT OF THE DISCLOSURE          This new apparatus for making foam from water, air and surfactant produces very small bubble foam by discharging the ingredients for the foam through passages that cause the stream of ingredients to be alternately expanded and contracted as by travel along tortuous passages to generate the foam.

A more uniform flow of foam is obtained as compared with foamers of the prior art where the foam sometimes broke up into alter-nating slugs of foam and air when discharged from pipes of large enough diameter to cause the foam to travel at low velocity.
