An adapter for connecting conventionally designed water coolers for use with flexible bag, paper box-type containers by means of closing the bottle-receiving opening with a plug-like, support member and providing means for communicating the bag with the opening.

The illustrated embodiments include an exciting generator and a power generator. Each of the generators includes a common tubular rotor. The armature of the exciting generator is maintained within the rotor and is fed through a control rectifier to the field of the power generator, which is also maintained within the rotor. The output voltage of the power generator is sampled for modulation of a radio transmitter which delivers power to a transmitting antenna. A receiving means maintained within...

A valve assembly wherein a valve cartridge, having honed valve surfaces in which a lapped valve spool is reciprocated, is supported in a housing by means isolating these surfaces from stresses due to bolt torques and other stresses to which the assembly is subjected.

A garage door-opener security system which automatically positively blocks any unauthorized opening of a sectional garage door that travels, guided by rollers, in a pair of flanking metal guide tracks. The security system is interconnected with a standard, automatic, garage door-opening mechanism that includes an electric drive motor. When the door reaches its fully closed position, a locking device, mounted adjacent one of the flanking tracks, physically inserts a locking pin into the trackway ...

A multi-purpose vehicle of a type having the ability to swing about a vertical axis like a turret and having a two-member boom pivotable about a horizontal axis with an operator's cage at its distal end. Controls are available at the cage for locating and manipulating various construction materials and equipment essential to the efficient construction of the post frame building.

A cage for use in a spinal repair system wherein a pair of inert, relatively open bone-graft contouring cages are disposed between adjacent vertebrae mounted to the boney structure of these vertebrae wherein the vertebrae will knit together and act as a single unit. The upper and lower surfaces of the cages follow an arcuate path for increased contact with the abutting surfaces of the vertebrae themselves.
