Abstract: A one piece fastener which uses spring action to fasten parts together. The fastener has a body which is inserted into a drilled aperture in the parts. An enlarged head on one end of the body is too large to enter the aperture. A spring on the other end of the body is normally too large to enter the aperture but can be retracted to a size to pass through the aperture. A stud has its head connected to the spring and its opposite end in threaded engagement with an internally threaded passage extending through the body of the fastener. Turning of the stud by a special tool applies a torsional force to the spring which retracts it so that the fastener can be applied to or removed from the fastened parts. Alternative embodiments of the invention employ various types of multiple stage springs to enhance the fastening power.

Abstract: A telephone call deferral system which allows incoming telephone calls to be deferred for a user selected period or until a user selected time. During the defer time, incoming calls are intercepted, the ring sound is suppressed, and the caller receives a voice message indicating that calls are not currently being received but will be at the specified defer time. Programming of the defer mode of operation is effected from the key pad of any telephone instrument connected with the telephone line of the user. An override system allows emergency calls to be completed from parties in possession of a special access code.

Abstract: The device of this invention includes a cleat disposed within a cavity formed by an exterior housing in a manner permitting the cleat to be moved between an extended position where the cleat is accessible to receive a boat line and a retracted position where the cleat is retracted into the cavity. The mechanism that allows the movement of the cleat between a retracted and extended position is within the cavity and includes a spring and a latching mechanism. The latching mechanism includes a latching member that pivotally moves within the latching mechanism between a latching position that holds the cleat in the retracted position and a release position where the latch memebr releases the cleat to the extended position under the influence of the spring. The latching mechanism allows for the cleat to be alternated between the extended and retracted position by successive depressions of the cleat into the cavity.

Abstract: A boxlight which serves as a source of light projected through a film transparency and focused on a photosensitive film in order to project the image on the transparency onto the film. The boxlight has an improved light source formed by pulsed xenon lamps arranged end to end to approximate a circle centered on the optical axis of the photoreproduction machine and contained in a plane perpendicular to the optical axis. Reflectors are provided in a circular arrangement extending around the light source circle and include reflective panels oriented at about 15.degree. to the optical axis. The circular configuration of the light counters cosine fourth losses and makes the light intensity pattern more uniform at the film plane.

Abstract: A combination simple and compound mitre gauge constitutes the subject matter of the present invention. The mitre gauge is intended to be utilized with power woodworking tools. The mitre gauge constitutes both a simple and compound gauge by utilizing an elongated member which slides in a groove on the supporting table and a support plate coupled with the member which is movable about a vertical axis and can be held in a given position by appropriate locking means. The support plate presents a vertical surface which mounts a guide that can be moved into one of two positions to vary the length of it. The guide may also be removed and a planar surface presenting shoe pivotally coupled with the support plate. The angle of the planar surface of the shoe may be varied and means is provided for locking the shoe in any given position.

Special tips on the arms are threaded through the laces of the glove to retain the device in place.

Abstract: A microprocessor based system for detecting leaks from underground gasoline storage tanks and the product lines through which the gasoline is pumped to above ground dispensers. Hydrocarbon sensitive probes spaced around the tank in monitoring wells detect gasoline leakage from the tank. Each probe can be independently programmed as to the threshold hydrocarbon concentration considered to be indicative of a leak. Pressure transducers sense the product line pressure and distinguish thermally induced contraction from true leaks by comparing the time required for a preselected pressure drop to occur during successive cycles. A time comparison is also used to detect the presence of excessive air in the product line. An alarm condition sensed by either type of sensor generates audible and visible alarm signals and automatically dials a programmed telephone number. The alarm times and dates are stored in memory and may be called up on the display screen.
