Abstract: ABSTRACT OF THE DISCLOSURE    Impurities are removed from a liquid by passing the liquid through an improved filter bed.  The filter bed comprises a mixture of oppositely charged particles of filter aid material, the particles normally having a surface charge in aqueous solution.  A portion of these particles are treated with a chemical compound to produce a surface charge that is opposite from the normal surface charge.  These oppositely charged particles clump in aqueous suspension, and produce a filter bed which is capable of removing suspended particles with very high efficiency, while maintaining a relatively low pressure drop across the filter bed.

Abstract: ROTARY VENEER CLIPPER     A B S T R A C T         A rotary veneer clipper has a pair of cutting blades spaced 180° apart on a rotary clipper shaft for cutting cooperation with a roller anvil below and parallel to the clipper shaft and over which sheet material passes.          The clipper shaft rotates intermittently on signal to cause one of its blades to clip the sheet.  The clipper shaft is driven by a pair of pneumatic drive cylinders mounted one to each of two crank arms connected to a common drive shaft.          The cylinders stroke once simultaneously to rotate the driven shaft alternately in opposite directions through 90° upon each successive clip signal.  When the drive shaft rotates in one direction, a first gear train transmits power from the drive shaft through a fir one-way clutch to the clipper shaft to rotate one of the blades downwardly and through 180° to clip the sheet.  When the drive shaft is rotated in the opposite direction, a second gear train transmits power from the drive   shaft to the clipper shaft through a second one-way clutch to rotate the other clipper blade through 180° in the direction of sheet travel to clip the sheet.  Locking means including a pneumatic locking cylinder limits clipper shaft rotation to exactly 180° upon each stroking of the drive cylinders to accurately index the cutting blades.  An optional blade speed control feature is also provided.

Abstract: ABSTRACT OF THE DISCLOSURE     In a heating apparatus comprising heating elements such as elongated tubular heating elements, radiating heat towards the heated space, and a reflector located behind said heating elements, the radiation-convection ratio is controlled by slowing or braking the upwardly directly current of convection air heated in contact with the heating elements.  A box-like member is provided above the heating elements in order to retain the convection air flowing upwardly, thus braking said upward movement of the air.  A cushion of hot air is thus created within said box-like member, which opposes the upward movement of additional heated air.  The box-like member is open rearwardly to permit escape of air, thus reducing both the velocity and the temperature of the convection air leaving the apparatus. This results in a much more uniform temperature in the space, for instance in a room, heated by the apparatus, the temperature near the floor and near the ceiling being substantially equal.

Abstract: ABSTRACT            Materials such as cellulose are rendered water repellent without objectionable degradation by contacting them with a non-laminar silicon halide vapor stream which reacts with hydroxyl groups to form a siloxane.  The non-laminar flow of the halide vapor is maintained over the reaction interval of the surface being treated and is exhausted at a position where further exposure of the material to the treating vapor provides a negligible improvement in water repellency.  This provides a suitable build-up of siloxane to achieve water repellency, and simultaneously prevents a cumulative hydrogen halide reac-tion which would otherwise have an unacceptably adverse effect on the long term strength of the treated materials.

Abstract: SELF CLEANING PULLEY FOR CONVEYOR BELTS               Abstract of the Disclosure A self cleaning pulley for conveyor belts in which a layer of elastomeric material such as polyurethane is applied to a cylindrical steel member, the layer having a plurality of generally longitudinally positioned resilient ribs extending radially outwardly from the body and spaced uniformly around the periphery thereof.  The spaced ribs define generally longitudinally spaced grooves for receiving foreign material carried between the pulley and the belt.          The surface of the body between the ribs slopes from a point near the longitudinal center of the pulley inwardly toward the opposite ends to assist in the flow of material dislodged from the belt and pulley to travel to the ends of the pulley where it is discharged.  The ribs are resilient but firm and are of such a shape that they will produce a scraping and vibrating action on the belt to dislodge any foreign material between the pulley and belt, causing it to be moved along the grooves of the pulley and to be dis-charged therefrom.   1.

Abstract: PATENT APPLICATION of George V. Miram and Erling L. Lien for THERMIONIC ELECTRON SOURCE WITH BONDED CONTROL GRID         Abstract For a grid-controlled electron source to operate at extremely high frequencies, as in planar triodes, the control grid must be situated very close to the emissive cathode.  Mechanical and thermal distortions have put minimum limits on grid spacings and hence on the maximum operating frequency of grid-controlled tubes.  To overcome these limits the grid structure is formed as a network of web members which are part of a laminated sheet having metal layers bonded to opposite surfaces of an insulating layer.          One metal layer is affixed to the emissive surface of a metallic matrix cathode and the other metal layer forms the control grid.
