Patent number: 4249868Abstract: A pump for pumping high viscosity lubricants such as wheel bearing grease comprising a pump tube adapted to be disposed within a container of the lubricant, a piston rod and piston movable within the tube, an outlet at the upper end of the tube, an inlet at the lower end, a check valve in the piston and a valve at the inlet. Upon the piston downstroke, the inlet is closed by the valve and lubricant is transferred through the check valve in the piston from below to above the piston. Upon the piston upstroke, lubricant above the piston is forced out the outlet and lubricant is drawn into the tube below the piston through the then open inlet. The inlet valve is constructed so that it cooperates with the piston to develop a vacuum at the inlet before the inlet is opened. Upon opening the inlet, there is then a sudden exposure of the lubricant surrounding the inlet to the vacuum which draws even high viscosity lubricant into the tube to prime it. Reliable pump priming is thus achieved.Type: GrantFiled: February 5, 1979Date of Patent: February 10, 1981Assignee: McNeil CorporationInventor: Jeffery M. Kotyk

Patent number: 4213339Abstract: A sensor for determining the presence of a particular volume of fluid within a plurality of reservoirs maintained as a portion of an automatic mixed drink dispenser. Fundamentally, the invention includes electrical contacts maintained within each of the various reservoirs, the reservoirs being aligned into rows and columns to form a matrix. A multiplexing circuit is interconnected to the rows of such reservoirs while a sensing circuit is interconnected to the columns thereof. The addressing of the rows of reservoirs by the multiplexer enables a signal to pass across the contacts and through the beverage maintained within the reservoirs, this signal being sensed by the sensing circuit interconnected between the columns of reservoirs. "Empty" reservoirs, or those having a low beverage level, may be quickly isolated by a determination of the row accessed and the column sensed to result in the failure of a contact to pass a signal.Type: GrantFiled: February 6, 1978Date of Patent: July 22, 1980Assignee: McNeil CorporationInventor: Joseph W. Shannon

Patent number: 4207647Abstract: A mobile apparatus for cleaning sewers, catch basins and the like includes a debris collection chamber mounted on the rear of a vehicular chassis. A vacuum conduit communicates with the chamber and is adapted to be lowered into the sewer. A vacuum fan also communicates with the chamber and draws air through the conduit and chamber thereby picking up debris from the sewer. As the debris enters the chamber, the configuration thereof creates a rapid decrease in the air flow velocity and otherwise interrupts the flow so that material entrained in the air is deposited in the chamber. The configuration of the chamber also permits facile discharge of the debris out of the bottom of the chamber in that one end wall of the chamber is swingable to open the bottom thereof. This same end wall also carries a hose reel for use in flushing the sewer. Because the debris which is picked up may well include water, means are provided to drain the water from the chamber.Type: GrantFiled: December 27, 1978Date of Patent: June 17, 1980Assignee: McNeil CorporationInventor: Philip C. Masters
