Title: Multi-base station cordless telephone
Inventor: ROSEN HOWARD B
IPC: H04W84/16
Filed: 2002-05-17
Granted: 2009-07-28
Abstract: The present invention is a system of at least one cordless telephone, a home base station and at least one non-home base station. A roaming cordless telephone out of range of its home base station will use a non-home base station to direct digital mode signals to its home base station. The home base station will convert the digital mode signals to analog signals and communicate them with the telephone network. Only a single direct line connection is needed for the home base station, as the digital mode signals and the analog signals communications do not interfere with each other. The user may potentially avoid long distance charges by using the non--home base station as a conduit while using the home base station as the telephone network site for long distance charge accrual. Further, the necessity for using a cellular telephone with the consequent charges is avoided.

Abstract: A conveyor for distributing food products consisting of a distribution conveyor (100) and a recirculation conveyor (115) where the distribution conveyor (100) has a plurality of slide doors (105) leading to weighing hoppers underneath. A plurality of stopper gates (110), each located downstream of and adjacent to one of the slide doors (105) in the distribution conveyor (100), momentarily holds the food products over the slide doors (105) thereby increasing the likelihood that the product will drop into a weighing hopper rather than recirculate, which helps prevent the food from cooling and becoming stale before it is bagged. Sensing and timing devices, such as level sensors (390), are used to control the actuation of the stopper gates (110) for the most efficient operation.

Title: Product diverter valve and collector apparatus for air drill seeding system
Inventor: GRODECKI LAWRENCE S
IPC: A01C7/20
Filed: 2003-06-12
Granted: 2007-03-20
Abstract: An improved collector assembly comprises a generally hollow body mounted below a product supply tank for receiving plural streams of materials metered from the tank. Individual upright passages through the body corresponding in number to the metered streams from the tank receive the gravitating product streams and direct each stream into either or both of an upper loading zone and a lower loading zone in the passage. A diverter valve associated with each upper loading zone can be set to close off the upper loading zone entirely while; opening only the lower zone or closing off the lower loading zone while opening only the upper loading zone. Thus, air streams passing transversely through the upper and lower loading zones respectively can be supplied with variable amounts of metered product, depending upon the position of the diverter valve within each passage. By providing multiple supply tanks and multiple collector assemblies, various product delivery scenarios can be achieved including single shoot, double shoot and triple shoot effects. In a preferred form of the invention all diverter valves are actuated by a common actuating mechanism for simultaneous adjustment.

Granted: 2007-11-06
Abstract: A two stage hermetic compressor which uses carbon dioxide as the working fluid. A pair of modules individually housing compression mechanisms are located at opposite ends of a module housing an electric motor. The modules are secured to one another when the compressor is assembled. Suction pressure carbon dioxide gas is compressed in the first compression mechanism to an intermediate pressure which is introduced into an electric motor module compartment. The intermediate pressure gas enters the second compression mechanism module through a suction port. A conical baffle is affixed to the upper compression mechanism module to protect the suction port from direct suction of oil and to separate oil entrained in the gas therefrom. The intermediate refrigerant gas is compressed to a discharge pressure and is discharged into a compartment defined in the second compression mechanism module. The discharge pressure gas is then exhausted to the refrigeration system.

Abstract: The present invention generally provides methods of geological analysis. The method includes collecting wellbore data from a well undergoing underbalanced drilling. The wellbore data is then correlated to a seismic data to predict geological properties away from the wellbore. In one embodiment, correlating the seismic data with the wellbore data involves converting the seismic data and the wellbore data to a one-dimensional numerical series, respectively. The two respective one-dimensional numerical series are compared to each other to produce a mathematical formulation relating the two series. In another embodiment, the wellbore data may be separated into different categories or classifications and individually compared to the seismic data. Preferably, the categories are compared to two or more variations of seismic data and their attributes to derive at unique "signatures" for the respective category. The signatures may then be used to produce "classification" maps of the wellbore data.

Abstract: An airboat and drive system for operating a pair of counter rotating air propellers that propel an airboat are described. An engine is mounted low in the hull of an airboat to lower the center of gravity and provide a more stable airboat. The drive system is connected to the engine through a drive shaft. The drive system includes a transmission, interconnecting frame, and counter rotating air propeller drive.  The interconnecting frame mounts the counter rotating air propeller drive above the transmission providing proper clearance for the air propellers with the hull of the airboat.

Abstract: A pipe repair clamp for temporary or permanent repair of pipes, comprises a metal clamping band to surround the pipe. The band is extended at both ends to form a hollow shape including a flat base, a wedge-shaped section and a convex rounded section. Elongated apertures are provided to allow passage for screw fasteners through the hollow shape. Narrow edges of the wedge-shaped sections are in contact with each other to form a substantially triangularly shaped space between the formed ends. A flexible inner sealing sleeve is disposed inside the clamping band and a pair of profile strips each having a major face for contacting the outer surface of said convex rounded section sliding over the convex rounded section when the fasteners are tightened or loosened to maintain the seating face perpendicular to the axes of the fasteners. An opposite seating face provides shoulder support for a plurality of screw fasteners. The plurality of screw fasteners are inserted into apertures of the profile strip wherein the tightening of the screw fasteners reduces the size of the triangularly shaped space and tightens the metal clamping band to compress the flexible inner sleeve sealingly against the outer diameter of the pipes.
