Title: Collapsible air deflector
Inventor: DWORAK GRZEGORZ J
IPC: F24F13/08
Filed: 1988-12-22
Granted: 1991-08-20
Abstract: ABSTRACT A collapsible air deflector for use with floor register commonly found in forced air heating and cooling systems has a plastic film body having two side walls joined by a curved back wall, a piece of elastic stretched between the side walls and a stiffener attached to the upper edge of the back wall.  To secure the air deflector to the floor register the lower edge of the back wall, the lower edges of the both side walls and the elastic are slipped under the floor register top rim.  When the air is blown through the floor register it inflates the collapsible air deflector, the curved back wall directs the forced air along the floor and this results in good mixing of forced air with the ambient air.     When the forced air stops to be blown through the floor register the collapsible air deflector collapses under its own weight and the weight of the stiffener, and covers the floor register preventing the cold air and dust from entering the floor register and the ducts.

Granted: 1992-10-13
Abstract: Panel Wall System Abstract A panel wall system is composed of a multiplicity of rectangular panels (P) arranged in closely spaced relation in columns and rows such as to define vertical junctures between horizontally adjacent panels and horizontal junctures between vertically adjacent panels and affixed at their upper edges to horizontal support members (HM) by mounting clips (52, 94) and joined at each vertical juncture to a vertically continuous vertical track member (VT). Each panel has a peripheral frame composed of a top member (24)  a bottom member (26) and a pair of side members (26) joined at the respective corners and a facing (20) of sheet material adhesively bonded to the frame.  Each of the frame members has a base flange portion (22a, 24a, 26a) having a back surface facing toward the support members and trash members, the back surfaces being flat and contiguous.  A seal is formed along each horizontal juncture by a horizontal gasket (55) on the back surface of the base portion of the bottom frame member (26) of the panel above the juncture that engages a flange (24i) on the top frame member (24) of the panel below the juncture.  A seal is formed at each vertical juncture by continuous vertical gaskets (59) on the vertical track (VT, 56) that engage the back surfaces of the base flanges of the respective side members (22) of the panels on either side of the juncture. Each frame member of each panel has a continuous rear flange portion (22d, 24d, 26d) of generally L-shaped cross-section joined to the base portion and defining a recess [22c, 24c, 26c) that opens outwardly toward the perimeter of the panel, the ends of the flange portions meeting adjacent the corners of the panels so as to form a continuous water drainage channel and spray trap at the panel perimeter.  The bottom and end recesses (26c, 22c) also constitute parts of slip joints, the other parts of which are a flange (24i) on the top frame member (24) of a vertically adjacent panel, a bottom closure (62) or a flange (56b) on a vertical track (VT, 56).

Abstract: An imbalance compensated drill bit is disclosed that takes advantage of undesired and destructive imbal-ance forces to prevent bit whirl.  Methods of designing and making such imbalance compensated drill bits are dis-closed whereby a drill bit body has at least one cutting zone with a plurality of cutting elements extending there-from and at least one bearing zone.  The bearing zone has a relatively smooth surface and is located at a position where the net imbalance force (from the cutting elements) is directed towards.  When the drill bit is rotated, the imbalance force presses the bearing zone against the bore-hole wall, and the bearing zone slips along the wall, thereby preventing the center of rotation to shift and create the destructive whirling motion.

Abstract: Case 2692 IMPROVED CLUTCH OR BRAKE INCHING ARRANGEMENT        ABSTRACT OF THE DISCLOSURE           A dual clutch far an inching arrangement in a load sharing drive which has two or more driving motors connected to a load through a dual clutch.  The clutch has two (or more) clutch units mounted side by side on a driving shaft with an inflatable, flexible tube in each unit for pressing respective friction shoes outwardly, when inflated, against a surrounding cylindrical drum.  The drum is mounted to a driven shaft.  The driving shaft has a central bore connected through a solenoid operated valve to a supply of pressurized air when the valve is in an operating position and to an exhaust when the valve is in a dump position.  Each of the tubes is connected to the central bore through a respective air line.  A needle valve in one of the air lines provides a restriction to the flow of air into and out of the respective tube.          The restriction is sufficient to substantially isolate the associated tube when the solenoid operated valve is operated to its dump position for a short time interval and then returned to its normal position.  Thus, during a short pulse of reduced air pressure caused by the operation of the solenoid operated valve, the air flows largely out of only one tube thereby reducing the volume of air dumped to cause momentary slipping and improving the dynamic response of the clutch.

Abstract: Abstract of the disclosure Adapter arrangement for electronic test equipment for wiring carriers such as circuit boards and similar, with an adapter board (8) in the form of a plated through hole circuit board to equalise locally raised connection densities between the regular basic grid (3) of the testing device and the variably arranged connection points (6) of the test specimen (4), with springy means of contact to equalise possible vertical variations in contact height on the test specimen.  The new and inventive feature consists of the fact that on each contact area (12, 13) on at least one side of the adapter board (8) is at least one cushion-like plug (14, 15) made from an electrically conductive springy elastomer, with the plug on each contact area being electrically insulated from the plug on each neighbouring contact area.  In another design form of the invention, the adapter board (8), which is provided with metal contact areas (12, 13) on both sides of the board, is constructed as a thin, flexible film which, because of its inherent flexibility, is in a position to equalise possible vertical variations in contact height (vertical to the test specimen plane) (Fig. 1).
