Abstract: ABSTRACT OF THE DISCLOSURE         In a surgically implantable shunt system for venting cerebrospinal fluid in the treatment of hydrocephaly, a valve and the method of testing it are disclosed.  The valve comprises an  elongate hollow valve body into which a flat plate tightly fits, partitioning the valve body into an outlet and an inlet chamber.  The flat plate has a circular aperture connecting the chambers and upon which rests a spherical ball of diameter larger than the aperture.  A flat spring biases the ball against the circular periphery of the aperture creating a circular seal and providing a precisely defined back pressure, low hysteresis and low susceptibility to bridging by debris.  Testing for leakage is accomplished by illuminating with light of a suitable fre-quency the aperture with ball seated and detecting any light transmitted therethrough.

Abstract: ESCAPEMENT MECHANISM AND BACKSPACE MECHANISM    FOR A MOVING PAPER CARRIAGE TYPEWRITER      HAVING DUAL PITCH CAPABILITY              Abstract of the Disclosure A mechanism which will function to allow the escapement of the carriage of a typewriter in one of two predetermined escapement pitches and be capable of backspace operation from a single backspace input for both pitches regardless of which is disclosed.  Escapement ratchets for the two selected pitches are combined, together with a backspace ratchet.  Each of the escapement ratchets are engageable by an escapement pawl and the engagement of a pawl with a particular ratchet will determine the pitch within which the escapement system will function.  A backspace ratchet is combined with the escapement ratchet and fixedly attached thereto to provide the backspace drive.  The backspace ratchet is selectably engageable by the backspace pawl for causing rotation in the opposite direction of that normally utilized for escapement.  All motion of the escapement ratchet or backspace ratchet is transmitted through a pinion mounted to the ratchet assembly and, in turn, is transmitted to the paper carriage rack.

Abstract: ABSTRACT The invention relates to a method for improved image reproduction in reproduction technology in which the recording is undertaken with a finer resolution than the scanning and the finer resolution in the recording is undertaken with a plurality of selectively drivable recording beams.  It essentially consists therein that the recording beams are separately drivable for recording half-tone raster points, in that the recording beams are combined in groups for the refined line reproduction and are driven by groups or in that the recording beams are individually employed in the refined line reproduction and in that the control information for the drive of the individual recording beams is obtained from the coarser scanning information.

Abstract: SPRAY BOOTH AND METHOD OF OPERATING SAME                     ABSTRACT A spray booth is provided with an air cleaning system to remove airborne particles for use in heavy pro-duction applications where large amounts of paint are sprayed and in which large quantities of airborne particles are collected without a substantial reduction in air flow through the booth as would fall below desired minimum standard of air flow through the booth.  Air flows through an open front face of the spray booth and across the piece being sprayed to a first water cascade means which has vertical water covered surfaces offset in the fore and aft direction to trap paint particles and which define vertical extending slots through which the air may pass.  The air is deflected downwardly from the first water means across the top surface of a water reservoir at the bottom of a spray booth at which surface further paint particles are trapped.  The air then directed upwardly through a down-wardly directed water spray wash which traps more airborne paint particles.  The water particles are removed from the air prior to its discharge from the spray booth.

Abstract: HIGHWAY TRAFFICE LANE AND ROAD EDGE REFLECTORS ABSTRACT OF THE DISCLOSURE           Reflectors for indicating, for example, the dividing line between traffic lanes and road edges include an above-the-road housing portion that has a spherical contour rising gradually from the road in all directions.  Impact, resistant solid metal shoulders have between them a light channel with divergent side walls and an upwardly and outwardly sloping upper surface.  Bridges across the channel, from shoulder to shoulder protect reflective lenses from tires and lift narrow two wheel vehicle tires up and over the lenses.  A removable assembly retains the lenses latched in place.  Wash openings directly above the lenses expose the lenses to direct impact by rain and reservoirs collect water for splash washing.  Bases for the reflectors can be surface mounted, imbedded for new road con-struction, or anchored by bolts in a shallow recess.  Extension below the road surface level of the assembly retaining the lenses permits larger reflector lenses in the housing of the reflectors imbedded and bolted in a shallow recess.  A removable model has a permanently secured base below road level with a detachable upper housing locked in place by a sturdy solid metal wedge between cooperating slots and lugs on the base and housing. This locking arrangement, the lens assembly retaining provision, and specially coded bolts securing the reflectors are vandal-resistant.
