Abstract: VERTICAL COUNTERFLOW HEAT EXCHANGER APPARATUS                  Abstract A counterflow heat exchanger is described with two sets of heat exchanger passages separated by heat ex-changer plates disposed in substantial parallelism within the exchanger and supported so that the passages extend substantially vertically.  The heat exchanger may be em-ployed as an air-to-air or as an air-to-water heat ex-changer and can be used to remove moisture or pollutants from hot exhaust air by condensation within the exchanger passages.  When employed as an air-to-water heat exchanger, the water is sprayed onto the surfaces of the upper ends of one set of passages so that it flows down their length, while air is transmitted into inlets at the lower end of the other set of passages and caused to flow upward out of outlets at the upper end thereof.  The ends of the heat exchanger plates are split into two end portions separated by a divider member and joined to different exchanger plates on opposite sides thereof to form the two sets of passages which allow the air and water to flow in opposite directions through such passages for counterflow heat exchange by direct lateral transfer through the thickness of the exchanger plate.

Abstract: AUTOMATIC FUNCTION MECHANISM FOR TYPEWRITERS               ABSTRACT OF THE DISCLOSURE         A method and mechanism for automatically performing typewriter functions such as backspacing a carriage,  The backspace mechanism is actuated by the insertion and removal of a ribbon cartridge that is placed on and guided by a ribbon cartridge platform and is especially suited for use in conjunc-tion with the correction of erroneously typed characters.  The ribbon cartridge carries a pair of cam surfaces that engage a pair of typewriter backspace coupled cam surfaces to actuate a backspace function upon insertion and again upon removal of the ribbon cartridge.  Therefore, automatic multiple back-spacing of the typewriter carriage occurs when performing an error correcting operation simply by inserting and removing a correction ribbon cartridge.   Although a backspace function has been selected for purposes of demonstration, the here-after disclosed embodiment may be utilized to actuate other typewriter functions upon the insertion and removal of the ribbon cartridge.

Abstract: ABSTRACT OF THE DISCLOSURE           A hydraulic turbo-machine incorporating wicket gates for purpose of controlling and closing down the flow of working fluid through the machine is provided with an annular ring gate selectively operable to take up any operating clearance between the casing and the adjacent axial edge of the wicket gates.  This arrangement makes it practical to incorporate relatively large initial clearances between the wicket gates and the fixed machine structure, so as to leave provision for natural contraction of such clearances during the life of the machine, due to shrinkage of the concrete or other expected or unexpected causes.  The operation of the annular ring as a piston within a cylinder is facilitated utilizing penstock water or oil under pressure as the motivating fluid.

Abstract: ABSTRACT OF THE DISCLOSURE         A valve of simplified construction, adapted to control fluid of high volume and pressure.  The valve plunger is a hollow metal tube, that controls fluid flow by moving radial slots in its peripheral wall back and forth across a seal.  The plunger is moved by an air or hydraulic cylinder which is connected to the plunger by a plate ring.  The plate ring has a series of holes therethrough that allow the line media to flow through, out of and around the plunger to create a balancing effect and thus decrease opposition to movement of the plunger, which opposition may be caused by forces created by the line media.  The improved valve utilizes double-acting seals to isolate a down stream port, and to seal off the increase in pressure downstream when the valve is closed.

Abstract: CHILD-RESISTANT SAFETY CLOSURE               ABSTRACT OF THE DI CLOSURE A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion onto which the closure is adapted to be threadably assembled.          The closure is of the type having an annular sidewall section having a flexible distal end portion provided with at least one interlocking member adapted to interlockingly engage at least one complementary interlocking member on the dispensing end of the container in such manner that interlocking engagement is achieved when the closure is in a fully closed position on the container neck portion.  Removal of the closure requires manual compression of the sidewall at locations straddling the interlocking members coupled with concurrent retrogressive turning movement of the closure.  An additive safety feature embodies providing a secondary interlocking engagement when the closure is partially removed.  Thus, such manual manipu-lation ordinarily must be repeated at each successive inter-locking position of the closure and is both beyond the ordinary capability of a child or other person of similar mental capabilities.          The closure features a frictionally slidable, fluid-tight sealing arrangement which in one aspect is operative to prevent leakage of the container's contents when the closure is in a fully closed position, and which in another alternative aspect is operative to prevent such leakage at and between both the fully closed and the succeeding partially removed interlocking locations of the closure on the container dispensing end.
