Abstract: A battery-powered washing unit is described which includes a motor drive unit driven by a DC battery pack with a yoke attached around the motor drive unit. An elongate and extendable handle is connected to the yoke for the user to grasp, and various brushes are connectable to the output shaft of the motor drive unit. Preferably the battery pack is sealed and self-contained and includes an integrated switch member at the top of the battery pack which consists of two powered positions, a low power and high power for various rotary speeds of the brush. Furthermore, the connection between the yoke and the motor drive unit consists of a locking mechanism having at least two locked positions, and a swivel position where the motor drive unit and the brush can swivel relative to the brush handle.

Abstract: A battery-powered carving knife is shown having a housing and a switch which connects and disconnects a battery to a motor. A drive mechanism including a worm gear together with a cam member causes reciprocation of reciprocating blade mounts to reciprocate back and forth in an out of phase fashion. The motor is positioned forward within the housing in motor receiving section, with the drive shaft of the motor facing rearwardly. The blade mounts are driven by the motor, and reciprocate in a position below the motor. The motor and blade mounts are positioned in front of a handgrip section, thereby improving the ergonomics of the device. Alternatively, the drive shaft can be positioned facing forward.

Abstract: A method and apparatus for attracting insects, especially black flies, sand flies and mosquitoes, in which the physical effects associated with the skin areas of prey-animals are simulated. Basic elements of a first embodiment of the apparatus include warmed elastic-walled holders of pulsed fluid which may be in the form of elastic tubing through which warm fluid flows in pulses arranged to produce various physical effects. Power for fluid heating and pulsing action may be provided by solar electrical, mechanical, nuclear, chemical or other source. Basic elements of a second embodiment of the apparatus include a weak spring suspended from a support and coupled to a vibration generator. The spring includes a deformable skin-like membrane therearound. Vibration is imparted to the spring and transmitted to the membrane to produce physical effects associated with movement of a skin surface of a prey animal. A heater may also be provided to heat the skin-like surface.
