The invention discloses a fluffing arrangement to provide separation between the records contained in a cartridge in order to facilitate random removal of an individual record. A free jet of low pressure directly impinges on the deck to maintain separation between the records.

A free-wheeling clutch sprag which is given a smooth and gradual sprag angle variation in the minimum sprag height range by giving at least one of the sprag surfaces which contacts a race the form of an involute cylinder.

A free flight sensor adapted for use in munitions utilizing ram air power to operate a mechanical safing means, sensing vertical velocity with a pitot-static pressure system and a two-axis fluidic accelerometer to sense vertical acceleration.

A lead free manganese containing range of glass compositions which have their surface layer rendered electrically conductive by an oxidizing process which does not produce water vapor.

A thermally driven pump for pumping fluids or driving a load includes a free piston oscillating in a cylinder. A coasting region for the piston is provided by means of a bypass having displaced ports in the cylinder walls. The bypass includes a thermal regenerator. A fluid to be pumped is introduced into the cylinder through a check valve, biased to be open in response to the pressure in the cylinder being less than the pressure of the source of fluid. Closing of the check valve is delayed until...

A free-standing shower stall including a base, wall panels joined to the base, a rail connected to the wall panels to impart rigidity to the stall, and a drain connection in the base which permits the shower stall to be placed in any desired location. A shower stall as described wherein the wall panels are plastic and are joined together by imperforate, water tight hinges which permit the panels to be folded for shipment in association with other parts of the stall and to be easily erected durin...

This invention is directed to an apparatus utilized for extracting earth cores from sub-sea formations. In particular, the apparatus may be dropped from a carrier vessel, whereupon it descends as a completely self contained unit to the ocean bottom. After penetration and extrusion by the apparatus in the ocean bottom an automatic condition-responsive device facilitates the extrication of the apparatus from the marine bottom by providing a sufficient buoyant force to lift the apparatus to the oce...

A bottom sampler to obtain a sample of the bottom of a body of water. A pair of clam shell jaws are pivotally connected to the base of an upright frame of the sampler. Hollow buoyant spheres are retained within the upright portion of the frame. The jaws are latched in an open position against the bias of resilient elements which close the jaws when the latch is released in response to impact with the bottom. Two weights, one on the back of each jaw stabilize the sampler during descent and fall o...

An anti-condensation device for mirrors comprising a printed circuit board heating element and a means for mounting said printed circuit board on the rear surface of the mirror is described. The mirror assembly herein provided with said heating element maintains the mirror viewing surface free from moisture condensation. In another embodiment of the invention the mirror assembly containing the printed circuit board additionally includes the incorporation of an electronic control package, which p...
