  • Patent number: RE30384
    Abstract: An improved solar cell designed for optimum efficiency is comprised of a plurality of series connected unit solar cells formed from a common substrate of semiconductor material. Each unit solar cell has spaced elongate sidewalls, and a "dead space" area between adjoining sidewalls of adjacent units is made substantially smaller than an active, light receiving area, extending between the opposite sidewalls of each individual unit. In addition, the width of the active area is concisely limited to ensure that radiation incident on the active area is incident at a point which is spaced from the p-n junction of each unit by no more than a predetermined optimum distance. Reducing the "dead space" area while concisely limiting the width of the active area provides improved solar cell performance without requiring focusing lenses.

  • Patent number: RE30387
    Abstract: Pulse generating apparatus which provides electrical heart-stimulating pulses only in the absence of normal heart activity. If the patient's heart has developed a life threatening arrhythmic condition the inventive apparatus automatically applies an electrical shock to the heart having sufficient magnitude to restore normal heart activity. The inventive apparatus features a redundant heartbeat sensing system which monitors two dynamic characteristics of heart function, for example, heart contraction and EKG. An electrical heart stimulating pulse is delivered to the patient's heart following the elapse of a specified period of time since the sensing of a dynamic characteristic indicative of a normal functional heart. Sensing control is automatically regained following successful heart stimulation, thereby inhibiting the application of further electrical pulses.

Two lengths of soft, lint-free wiping cloth extend through the nip with the opposed surfaces of the cloth at the nip defining a part of the path. The guide includes first and second generally parallel guide plates having opposing surfaces defining an opening which is part of the path. The opening defined by the guide plates has an inlet end and an outlet end, and the plates are in fixed position with respect to the film cleaning apparatus with the outlet end of the opening proximate the nip.

  • Patent number: 4218802
    Abstract: Drain cleaning apparatus utilizing a flexible snake which is inserted into a drain pipe and rotated so as to cut through a blockage or obstruction in the drain pipe. The apparatus includes a manually actuated chuck operable while the apparatus is in operation, for holding the snake relative to the apparatus thus enabling the operator to feed the snake forceably into the drain pipe and into cutting engagement with the obstruction, and auxiliary means operable to lock the snake securely with respect to the apparatus so as to permit the torque of the apparatus' drive motor to be applied to the snake.

  • Patent number: 4218805
    Abstract: Suction cleaning apparatus comprising a container adapted for the collection of a liquid is provided with an inlet for connection to a suction head adapted for picking up liquid whereby incoming air flow is directed substantially radially inwardly relative to the container and impinges directly on an inner wall whereby it is spread in substantially equal and opposite streams around the interior of the container. The inner wall surrounds a suction inlet whereby suction is applied to the interior of the container and the arrangement minimises the tendency for a vortex to be generated in air flow towards such suction inlet, thereby reducing the tendency of foam to be produced on the surface of the collected liquid within the container.
