Abstract: The apparatus includes an elongated wash tank and an elongated rinse tank each having a plurality of conduits disposed adjacent to the bottom thereof. Conduits in the washing tank are connected to a Wye. One inlet branch of the Wye is supplied with air at a pressure of at least 15 psi and the second inlet branch of the Wye is connected to a recirculating pump having an output of at least 30 psi. A mixture of pressurized air and water is discharged from apertures in the elongated conduits and forms vortices in a bath of water held in the tank. Window blinds are suspended in the tank in contact with the vortices. The elongated conduits in the rinse tank are supplied with air at a pressure of greater than 15 psi. Air is discharged from the elongated conduits in the rinse tank through vertically directed openings. After the blinds are washed in the wash tank they are inserted in the rinse tank and thereafter removed and air dried.

Abstract: A cleaning device for surgical implements comprising a base and upstanding bristles, including at least one sharp vertical edge and a flat top. The bristles of one section are short and rigid, the bristles of the second section are long are relatively flexible, and the bristles of an intermediate section vary in length from short to long with a substantial portion of the intermediate bristles being relatively rigid so that a suction tube can be cleaned by pressing it downwardly over the bristles. The base carries a resilient pad and a securing member such as a double-faced adhesive tape for mounting the unit upon a support surface.

Abstract: Window blinds are cleaned by suspending a blind in a tank containing a bath of water. Pressurized air and water are discharged from openings in elongated conduits into the bath so as to form vortices contacting the blind. After the blind is washed, it is rinsed and dried.

Abstract: An electromagnetic induction type hearing aid which comprises (1) an electromagnetic transmitter having an input for receiving a radiated acoustical signal and an output for radiating an alternating electromagnetic signal whose frequency components are determined by the input signal and (2) a wireless magnetostrictive vibrator of bimorph design and of biocompatible material and which is adapted to be surgically implanted on one of the bones of the ossicular chain in a spatial operative relationship to the transmitter output without the need for mechanical anchoring and without any components passing through the boundary of the middle ear of the user. The vibrator is further responsive to the electromagnetic signal radiated from the transmitter and vibrates the ossicular chain in response to such radiated electromagnetic signal to stimulate the inner ear to create the perception of sound to the user.
