The vacuum generating system has a variable speed motor such that the motor speed can be adjusted by a user dependent upon the size or type of animal being groomed. The vacuum apparatus also has a noise reduction system including a muffler, an impeller with long fan blades, and multiple air flow path redirections of air traveling through the housing.

Abstract: A golf ball washing device is provided which includes an internal overflow. The golf ball washing device includes a shell having an cavity which holds cleaning liquid, an agitator movably connected within the cavity, a stand having a hollow portion attached to the shell, and an overflow passage. In preferred embodiment, the overflow passage is a tube having a first end which is connected to the cavity and a second end which communicates with the hollow portion of the stand. The shell is cast to encase the overflow passage. During use, when the agitator mechanism causes the cleaning liquid to splash or otherwise rise above its normal level within the cavity, the overflow passage drains the excess cleaning liquid from the cavity into the stand. With this configuration, the overflow passage prevents cleaning liquid from spilling or splashing outside of the shell.

Abstract: A combined nozzle and cleaning fluid dispenser for a fluid vacuum cleaning system is provided. The combined nozzle and cleaning fluid dispenser is for simultaneously applying a cleaning fluid and a vacuum force to a surface or object. The combined nozzle and cleaning fluid dispenser includes a hollow, rigid wand attached to a suction chamber having an open, free end. Attached to the wand is a cleaning fluid sprayer which includes a valve, a lever arm and a spray head for dispensing a cleaning fluid. In accordance with the present invention, the spray head is positioned within the suction chamber. In this arrangement, the cleaning fluid is substantially prevented from being dispensed from the suction chamber unless the suction chamber is in contact with a surface to be cleaned. The combined nozzle and cleaning fluid dispenser of the present invention not only prevents against pooling or puddling of the cleaning fluid but also allows for controlled and precise dispensation of the fluid.

Abstract: An apparatus of spreading a fluid on the floor includes four rectangular application rotating bodies partially overlapping each other, and four nozzles supplying the fluid provided in rotation areas of the respective application rotating bodies. The rotation position of the application rotating body is detected by a light shielding plate and a photosensor. A control portion controls each component so that the fluid is applied onto the floor from a tank through the nozzle by a pump when the application rotating body is not directly under the nozzle. As a result, the apparatus of spreading a fluid on the floor capable of optimally controlling the quantity of the fluid to be applied according to the application condition can be provided.

Abstract: A scale modelling centrifuge has a relatively massive rotary circular base wall, which may form part of a drum, possibly with a detachable peripheral wall either carrying an annular sample-receiving trough or constituted by such trough, or which may have mounted therearound a plurality of sample-receiving containers.

Abstract: A feed accelerator system for use in a centrifuge, the system comprising a conveyor hub rotatably mounted within a rotating bowl, the hub including an inside surface and an outside surface. At least one feed slurry passageway is disposed between the inside surface of conveyor hub and the outside surface of the conveyor hub, and at least one helical blade having a plurality of turns is mounted to the outside surface of the conveyor hub. A vane apparatus is associated with the passageway and is disposed between two adjacent turns of the helical blade. The vane apparatus may include an inwardly extending baffle and/or an outwardly extending accelerator vane. Alternatively, a U-shaped channel may be associated with the passageway, the U-shaped channel including a plurality partitions attached to the discharge end of such channel so as to form a plurality of discharge channels and a flow directing and overspeeding vane disposed within each channel, each vane having a different forward discharge angle.

Abstract: A plastic tool with a handle and trigger at one end and a pair of jaws (one of which is moveable) at the other end which are inserted into a biodegradable paper cleaning pad filled with cleaning/disinfectant and/or deodorant materials. The lower jaw of the tool is moveable by way of a trigger near the handle. When depressed the trigger compresses a lock spring and moves an actuator rod down the barrel which operates a hinge to open the jars far enough to be inserted into the cleaning pad. The open jaws surround a paper tab which forms the center of the double-walled cleaning envelope. On the release of the trigger the coil operating spring decompresses and moves the actuator rod back toward the handle locking the jaws over the center tab of the cleaning pad. Facilitated by a nominal 15-degree bend in the barrel of the cleaning tool and the flexible tip of the cleaning pad, the cleaning tool can reach all surfaces within the toilet to clean the unit.

Abstract: A vehicle finishing apparatus provided with a vehicle finishing pad having slits cut in the pad in patterns other than parallel, straight and perpendicular to the brush axis so that the individual pad strips make finishing contact with the vehicle surface over an area having a transverse width which is greater than the strip width. The slits in a preferred embodiment are cut in a curved fashion, thereby creating a longer edge surface on the strips and increasing the transverse contact area with the vehicle surface as well as improved edge contact with the vehicle surface.

Abstract: A vehicle-mountable push broom has a generally horizontal frame provided with a plurality of transverse downwardly-opening generally C-shaped channels, and a plurality of removable bristle strips positionable one in each channel. Each strip has a holder specifically configured to be accommodated within the channel, and a plurality of bristles mounted in and extending downwardly from the holder. The strips are loosely held within the channels, such that the holders are permitted to rock within the channels, for example through an angle generally in the range of 10 to 20 degrees.

Abstract: A centrifuge rotor has a central hub with a mounting recess therein, a ring disposed concentrically about the hub, the ring having a plurality of cavities formed therein, and a relatively thin web connecting the hub and the ring. The web defines a localized region which exhibits a stress therein that is greater than the stress present in any other portion of the rotor when the rotor is operating at the predetermined operating speed, so that, over operation time, the probability that rotor failure will occur only in the web is enhanced. The cavity ring has an annular rim with an upper surface having a predetermined reference line defined thereon. A portion of the upper surface of the rim defined relative to the reference line is relieved. The radial location of the relieved portion of the upper surface with respect to the reference line is governed in accordance with the axial position of the web with respect to the center of mass of the ring.
