Abstract: A sewer cleaning system includes a water tank, a pump operatively coupled to the water tank, a water hose operatively coupled to the pump, a vacuum-generating system, a vacuum hose operatively coupled to the vacuum-generating system, and a debris tank having a forward bulkhead defining a fluid chamber. The bulkhead includes a debris sieve configured to allow water in the debris tank to flow through to the fluid chamber while retaining particulates in the debris tank. The sewer cleaning system further includes an extraction pump in fluid communication with the fluid chamber and configured to extract the water in the fluid chamber. The extraction pump is in fluid communication with the water tank so as to send the extraction water from the fluid chamber to the water tank for re-use. A method for cleaning a sewer line is also disclosed.

Abstract: A lubrication system is provided for a centrifugal pump of the type having a bearing housing for maintaining the lubrication of a plurality of pump shaft rolling element bearings. The system includes a lubricant reservoir forming a volume, and having at least one supply port for supplying lubricant to the bearing housing, and at least one return port for returning lubricant to the lubricant reservoir. A lubricant recirculation pump has at least one supply stage and at least one suction stage. A connector is provided between the supply port of the reservoir and the suction stage of the lubricant recirculation pump for the supply of lubricant to the suction stage of the recirculation pump. A connector is also provided for interconnecting the supply stage of the lubricant recirculation pump to the bearing housing for the delivery of lubricant to the bearing housing.

Abstract: A method of assembling either an electric motor powered car or an internal combustion engine powered car along a single assembly line. The method comprises providing a car chassis having a general block shaped drive system receiving area and, selecting a drive system from a group consisting of an electric motor drive system and an internal combustion engine drive system. The method then comprises connecting the selected drive system to the chassis in the drive system receiving area.

Abstract: A car is disclosed having a chassis, an engine, a drive axle assembly, and an engine mounting system. The engine mounting system includes a front engine mount and a rear engine mount. The front engine mount has a first load bearing tie member pivotably connected to the chassis and directly rigidly attached to the engine block. The rear engine mount has a second load bearing tie member directly attached to the drive axle assembly and directly rigidly attached to the engine block. The engine block and two tie members form a rigid unitary assembly.

Abstract: An air intake system having a housing and an air filter. The housing has an air inlet, an air outlet, and an air conduiting path therebetween. The path includes changes in air flow direction and velocity at least four times each along the path.

Abstract: A switch lock having a reliable side-opening door and an improved rotatable handle is provided for use in motorcycle ignition systems. The side-opening door is rotatable between an open position wherein the lock plug assembly is exposed and a closed position wherein the lock plug assembly is covered. In the closed position, the side-opening door forms a part of the handle by fitting tightly against the side and top of the handle. The side-opening door also has a latch which receives and securely retains the side-opening door in the closed position. The handle is rotatable into a finite number of predetermined engagement orientations and is lockable at some or all of these orientations.

Abstract: An air filter having a filter element, a support, and a seal. The support is a substantially flat and flexible screen to allow air to pass through the support. The seal is connected to a perimeter of the support and across a middle section of the support to form two sections. The filter element is attached to the support at only one of the sections.
