Abstract: A hinge, providing a swinging function for a first object attached thereto with respect to a stationary object attached thereto, includes a first leaf; a second leaf; and a pintle. The first leaf has a first knuckle. The second leaf has a second knuckle forming a volume for receiving said pintle. The second knuckle has a contact arm located within the volume. The pintle has a first stop surface feature and a second stop surface feature. The first stop surface feature causes the swinging function of the first object to stop when the contact arm of the second knuckle engages, by contact, the first stop surface feature. The second stop surface feature causes the swinging function of the first object to stop when the contact arm of the second knuckle engages, by contact, the second stop surface feature.

Abstract: A lawn rake with debris pickup capability is disclosed. The lawn rake is particularly useful as an implement for raking leaves/debris from a grassy lawn into piles, then to encircle/grasp the debris pile for lifting, transport and dumping. In using the Lawn rake, the operator does not have to bend over to pick up leaf/debris piles.

Abstract: A lateral view extender device for Homonymous Hemianopsia is disclosed. The device is particularly useful with eyeglasses having a pair of lenses and a nose bridge separating the pair of lenses. The device includes a dichroic half lens having the combined optical properties of a reflector and a see through lens and means for fixing the dichroic half lens to the nose bridge of the eyeglasses in optical registry with one lens of the pair of lenses for providing at least one optical path through the one lens of the pair of lenses and the dichroic half lens and at least one other optical path over the dichroic half lens. The dichroic lens forms an interior angle with the one lens of the pair of lenses for providing mirror images on the dichroic lens within the one optical path thereby extending the lateral view of a person suffering from Homonymous Hemianopsia proportionally to the interior angle formed between the dichroic lens and the one lens of the pair of lenses.

Abstract: A corona generating device having a corona wire and a shield partially surrounding the wire has an improved built-in cleaning mechanism. The cleaning mechanism includes a cleaning member slidably mounted within the shield, which member is driven back and forth along the device by a belt connected thereto. The belt is driven by a pulley rotatably mounted on the device, the pulley having gear teeth formed therein which are adapted to mesh with a drive gear. By using conventional quick-disconnect electrical connectors to connect the corona wire to a source of voltage, and a suitable supporting member to both support the device and position the pulley so that it meshes with the drive gear, the device can be easily removed from an electrostatic reproduction machine for routine maintenance, and easily inserted back into the machine.
