A drive shaft assembly for a portable lathe includes a first hollow shaft and a second shaft axially aligned with and telescopingly received in the first shaft, for permitting an effective length of the drive shaft to be altered within a limited range. The first and second shafts are also rotatable relative to each other. Opposite ends of the first and second shafts have uncovered joints including...

A method and apparatus for permitting global roaming between two communication networks which utilize different authentication schemes. The authentication interoperability function (AIF) and method translate between the authentication schemes of each network, for example, a triplet-based network and a shared secret data (SSD) network. When a user from a network that natively uses SSD authenticatio...

A safety tassel for terminating a pair of pull cords of a venetian blind or similar window covering which includes a pair of tassel halves releasably engageable with each other, each half attachable to a respective one of the pull cords and having grooves which define a cord opening when the halves are engaged and. which receive and engage a tassel end of a connector cord and, when disengaged, rel...

An integrated air conditioning and hot water supply system for conditioning air and supplying hot water to a building is described. The system incorporates a hot water tank in the system which feeds a heat exchanger to heat air which is recirculated from the building when required during cool weather periods. A combined air dehumidification device and cooling device are also provided to dehumidify...

A modulation/demodulation receiver having a reference signal in a digital communication system. A method for signal processing and cochannel interference signal removal in the receiver includes the steps of processing an input signal to be at a predetermined multilevel, feeding the processed signal to an adaptive equalizer, determining the type of the multilevel from the signal applied to the adap...

On various occasions it is required to simultaneously be able to enjoy food and drink without there being either tables or other suitable free surfaces available. This requirement has been solved through a plate with at least one section (7) for food and a separate section (1) for placement of a drink container (6), between these two sections under the plate a furrow (9) together with the plate's ...

Each of the intersection lines between the side surface (18,19) and the top surface (16) of the cutting insert forms a main cutting edge (24,25) respectively. Protruding ends (22,23) respectively intended to plane out the machined surface. The main cutting edges and bevel faces are separated in each corner of smoothly rounded corner edges (28,29) respectively. The indexable cutting insert (13...

A fuel refilling assembly for receiving a filling nozzle to open and close a filler neck of a fuel tank. The refilling assembly has a housing attached to the filler neck to receive the filling nozzle. A pressure valve and a vacuum valve are mounted to the housing. The valves move between seated and unseated positions to automatically equalize the pressure within the filler neck, a filler pipe and ...
