Abstract: ABSTRACT     The Seal grid system for a rotary piston mechanism of the Wankel type comprises apex seal blades, a conventional side seal assembly consisting of side seal stripe and button or seal pins carried on one side face of the rotary piston and a sealing surface portion or rib projecting axially from the other side face of the rotary piston and extending end-lessly around the rotor face.  The seal surface portion is spaced radially inwardly from the peripheral surfaces of the rotary piston to expose a portion of the other side face to the pressurized gases in the working chambers so that the axial forces on each of the side faces of the rotary piston are at least in part counter-balanced.

Abstract: ABSTRACT          Abrasive-containing tobacco slurry is homogenised by passing radially outwards between the facing surfaces of two closely adjacent coaxial rings of tungsten carbide to impinge violently against a tungsten carbide surface surrounding the rings.  The occurrence of local areas of wear in the facing surfaces is minimized by rotating one ring relative to the other.

Abstract: TRACTOR MOUNTED SCRAPER BLADE              ABSTRACT OF THE DISCLOSURE           A material handling assembly has a frame for attachment to the three point hitch of a tractor.  A laterally swingable boom extends rearwardly from the frame and has an upright shaft at its rear end rotatable about an upright axis for suspending a reversible scraper blade whose angularity may be varied as the shaft is rotated.  The blade is releasably attached to and tilt-able relative to the shaft.  All four functions of raising and lowering the frame, swinging the boom, varying the angularity of the blade and tilting the blade are hydraulically controlled.  A special four bar linkage coupled with the shaft provides for wide blade angularity adjustment.  A fluid bypass arrange-ment interconnects the swing and angularity functions to accommodate for excessive loads which may be encountered when the attitude of the blade is to be varied in accordance with desired grading operations.

Abstract: Abstract of the Disclosure A programmed valve system for positioning control having a first two stage valve assembly operable for raising a load and a second two stage valve assembly for lowering the load.  Each of the second stages has a poppet with a parabolic contour which is dimensioned with orifice parameters to provide substantially linear flow rate change for mini-mized shock when one of the second stage poppets closes and the other opens.  In the raise assembly, the pilot stage outlet orifice has a cross-sectional area substantially larger than that of the inlet orifice so that the second stage poppet opens much more rapidly than the closing thereof thereby to minimize overshoot when the pilot stage is actuated to the open position.

Abstract: ABSTRACT OF THE DISCLOSURE A band-pass filter circuit which is composed of a band-pass filter for removing noise components from an input sine wave, a phase detector for detecting a phase difference between input and output signals of the band-pass filter, a loop filter supplied with the output from the phase detector, and automatic control means for effecting control by the output from the loop filter so that a differnece between the frequency of the input sine wave and the center frequency of the band-pass filter is reduced to zero.  In the case of achieving carrier recovery in a burst mode, the loop filter selected to fit for each particular purpose is used, by which high-speed pulling-in is possible even if a narrow-band filter is employed as the band-pass filter for the removal of noise components.  Also, high-speed and high-precision pulling-in is achieved when many bursts of different frequencies are applied in one frame period.  Further, when common and individual frequency variations exist at the same time, high-speed pulling-in is also achieved for each burst.

Abstract: Abstract of the Disclosure A spring-drive for load change-over switches of tap-changing regulating transformers.  The drive is intended for use in connection with change-over switches having main arcing contacts and current-carrying contacts engaged and disengaged in a pre-determined sequence during change-over operations.  The drive includes at least one compression spring arranged between a first slide operable by an eccentric driven by a drive shaft, and a second slide driving the change-over switch by the intermediary of a crankshaft.  The crankshaft is adapted to be arrested at the end of each operating cycle when the current-carrying contacts of the change-over switch are in engagement by a pair of pawls each engaging one of a pair of recesses forming part of the crankshaft. To avoid malfunction of the drive mainly due to changes in temperature of its surroundings, a pair of additional recesses form-ing part of the crankshaft are provided.  Each pair of additional recesses is arranged ahead of one of the pair of recesses as seen in the direction of motion of the crankshaft so that the crankshaft may be arrested by one of the pair of pawls when the crankshaft is in a position that corresponds to the closed position of the main arcing contacts, but short of the maximal travel thereof that corresponds to the closed position of the current-carrying contacts.

Abstract: Abstract of the Disclosure A set of selectively collapsible and expandable insulating curtains and the method of making same, the curtains each having a plurality of collapsible tubes, preferably of plastic material, extending longitudinally across the width and superimposed one on top of the other in a row in the direction of curtain height.  Each tube has an upper wall and a lower wall secured together by bands of adhering contact on opposite sides of the tubular cavity.          Additional bands of adhering contact secure superimposed tubes to each other longitudinally along midsections of the upper and lower walls.  The side bands of contact define fold lines allowing collapse and expansion of the tubes as the curtain is raised and lowered, respectively, in the manner of a venetian blind.  Each curtain may include additional rows of superimposed tubes one adjacent to the other in the direction of curtain thickness.  In making the curtains, a plurality of thin-film layers are wound about the periphery of a forming member with bands of adhering material interlaminated between adjacent strips, the width of the midsection bands corresponding to the desired width of the expanded tubes and bands between successive adjoining layers being in a staggered relationship.  After winding is complete, the superimposed layers are cut transversely, removed from the forming member and straightened to form a curtain.  The number of spaced bands may be such that the layers may also be cut longitudinally to provide a plurality of curtains.  After straightening, means may be secured to the tubular structure for hanging and selectively collapsing and expanding the curtains.
