Title: Operatively stationary pool cleaning apparatus
Inventor: GOETTL JOHN M
IPC: E04H4/16
Filed: 1990-03-09
Abstract: Operatively Stationary Pool Cleaning Apparatus Abstract A  pool cleaning apparatus weighted to rest on a pool  bottom.  The apparatus includes a manifold for dis-charging  water  under pressure into a plurality of sweep hoses  and into a plurality of venturi jets.  The sinuous action  of the sweep hoses places small foreign particles in  suspension,  and  tends to draw larger debris such as leaves toward the inner ends of the hoses.  The jets dis-charge  into  a venturi chamber which is spaced above the pool  bottom  by  support  legs.   This induces a flow of pool  water into the venturi chamber, carrying the larger debris  through  the  venturi chamber for collection in a removable debris or leaf bag.

Title: Thin panel video display screen and system
Inventor: HART EASTMAN
IPC: G02F1/1333
Filed: 1990-11-21
Abstract: ABSTRACT          A vacuum tube video display screen and imaging device utilizing waveguides to disperse a horizontal line of image over the vertical area of the viewing screen and an array of closely spaced liquid crystal lines to permit passage of light from the dispersed image through to a phosphor coating.  By deactivating lines of liquid crystal in a sequence corresponding to the sequence of image lines scanned along the optical waveguides a complete picture is formed on the viewing screen.  In a further embodiment an optical waveguide sheet disperses a single pixel of image over the entire viewing screen, and orthogonal arrays of closely spaced liquid crystal lines are sequentially activated to permit passage of light to the corresponding pixel on the viewing screen.  An imaging device utilizes orthogonal arrays of closely spaced liquid crystal lines extending across the image plane to permit passage of a single pixel of light to a photoemissive material co-operating with an anode, which produces an electronic signal corresponding to the intensity of light in each pixel.

Abstract: CAMSHAFT ADJUSTER AND TENSIONER Abstract A camshaft adjuster mounted between a taut strand and a slack strand of a chain connecting an intake camshaft to an exhaust camshaft has two tensioning shoes which are urged by a spring away from each other and against the inner sides of the chain strands.  One tensioning shoe is mounted on a reciprocable piston within which a plunger carrying the other tensioning shoe is slidable against the force of the spring.  The piston is moved against the taut strand by pressurization of a pressure chamber through a nonreturn valve and the plunger is moved with the piston so that the taut and slack strands are moved together and compression of the tensioning spring is thereby maintained relatively constant.  A damping chamber may be provided with throttling bores in the piston and/or plunger to control the damping effect.
