Abstract: TITLE: AUTOMATIC BUILDING BLOCK LAYING PANEL-FORMING MACHINE                 ABSTRACT OF THE DISCLOSURE            A machine for automatically laying building blocks and the like into a panel.  It includes a supply coveyor for feeding a predetermined number of blocks into the machine in proper sequence to form a course, the blocks standing on end. An in-feed support conveyor receives the blocks while still in upright position.  A feeder carriage reciprocates over the in-feed conveyor and carries flow-guns for applying adhesive to the exposed upper ends of the blocks and to the exposed edges of the blocks at different times.  The carriage is provided with clamps which, as the carriage advances, successively clamp the blocks for pivotal movement about transverse axes.  Beyond the in-feed conveyor, is a course-forming and supporting conveyor which is transversely arranged relative to the in-feed conveyor and, over which the carriage advances, which has pairs of parallel guides for receiving the clamped blocks on the feeder carriage. As the blocks are moved by the advancing carriage into a pair of the aligned guides, they are tilted into horizontal positions, by movement about the transverse clamp axes, and arranged in the guides as a horizontal row of spaced blocks, and are later re-leased by the clamps.  The released blocks are slidably pushed together in the guides and centered relative to the conveyor by ram units so that they will adhere as a horizontal course. The course-forming and supporting guide conveyor is advanced in-wardly or rearwardly intermittently to advance the formed courses successively into engagement with a transfer unit which re-ciprocates rearwardly and forwardly above the conveyor to suc-cessively grip the adhered courses, and at the same time to align other pairs of guides successively with the rows of blocks supplied by the feeder carriage.  The transfer unit moves the formed courses successively over a panel-support elevator where they are released, the elevator being lowered gradually so that the courses are laid thereon, with the courses then adhering to form a panel.  Automatic programming and timing controls are provided for bringing about all of the operations in proper sequence.                             ?

Abstract: COLOR CORRECTOR                 ABSTRACT OF THE DISCLOSURE            An automatic color corrector is disclosed for use in a color television receiver.  To enable color correction of chroma signals within a selected range of the fleshtone axis, the  outputs of the chroma demodula-tors are sensed to develop a control signal.  In response to the control signal, a color modifier automatically reduces the gain of the (B-Y)demodulator by a predetermined factor.  Preferably, the color modifier also adds a pre-determined negative (B-Y) component of fixed value to the output of the (B-Y) demodulator. As a result, fleshtone chroma signals which otherwise have an unnatural cast are given a more natural color and the addition of the negative (B-Y) component causes the resultant color correction to be centered about the fleshtone axis.

Abstract: 1022.022 S P E C I F I C A T I O N        ROTARY SLICING TOOL FOR MAKING NEAT, COMPLETE SLICES IN A FOOD PROCESSOR               INVENTOR: CARL G. SONTHEIMER     ABSTRACT OF THE DISCLOSURE     A rotary slicing tool is provided for use in a food processor and having an elongated hub with a horizontal disc-like member secured to the top of the hub for rotation therewith carrying an elevated slicing blade.  The disc-like member has a horizontal area which may include a down-turned flange around its perimeter and has an arcuate slot extending from the hub out to the periphery of the disc-like member.         The elevated arcuate slicing blade is mounted on the disc-like member behind the slot with the cutting edge projecting forward and elevated above the level of the horizontal area and facing forward above the slot for slicing food items, with the delicate slices passing down through the slot.  The arcuate slicing blade is mounted on an elevated arcuate rim of the disc extending forward toward and above the slot.          For advantageously avoiding any smashing, stripping, shred-ding or other interference with the performance of a neat, uniform and complete slicing operation on each slice of the food items, an integral gradually sloping shoulder joins the horizontal area of the disc-like member with the elevated rim on which the arcuate slicing blade is mounted.  Both ends of the slicing blade are contoured to conform with the rotational direction of travel; thus, the outer end conforms with the contour of the periphery of the disc-like member, and the inner end conforms with the contour of the hub, and the cutting edge is spaced well forward of the shoulder near both ends of the slicing blade.  The shoulder is also gently sloped, rounded and contoured to conform with the relative direction of motion of the disc with respect to the delicate slices of food being formed and passing down through the slot in the fast-turning tool, whereby food items which are fed toward the disc-like member are uniformly sliced by the blade with the slices being gently deflected by or missing the gradually sloping contoured shoulder without being smashed or otherwise damaged particularly near the outer end of the fast-revolving slicing blade.  In another embodiment the elevated rim on which the slicing blade is mounted comprises a relatively wide platform which in effect spaces the cutting edge farther ahead of the connecting shoulder to avoid interference by the shoulder with the delicate slices passing down through the slot in the fast-turning tool.

Abstract: ABSTRACT OF THE DISCLOSURE     Fluid material having solids entrained therein is injected under high pressure through a nozzle disposed tangentially of a cylindrical housing. Groups of impactors are spaced circumferentially about the housing interior and include multiple rows with adjacent rows being staggered.  The solid material strikes the impactors thereby reducing the size of the material. The fluid carries the solids circularly around the housing with the solids gaining speed between groups of impactors.  The housing has an axially positioned discharge chute which is vertically disposed and adjustable in height.  The mixture circulates through the housing in a vortex pattern, and exits through the axial discharge.  The heavier solids are urged radially outward under centrifugal force and constantly strike the impactors until their size is reduced sufficiently to allow them to follow the mixture through the axial discharge.

Abstract: In the Canadian Patent Office Application for Patent and Offer of Disclosure for Public Dissemination Inventor:  William J.  Lado Owner   Pettibone Corporation Title:     SYSTEM FOR ONE-HANDLE CONTROL OF TWO WINCHES DURING HOISTING OF CLOSED CLAMSHELL, WITH DIFFERENTIATION               ABSTRACT OF THE DISCLOSURE      The invention relates to cranes or the like in which two hoist lines control a clamshell bucket.  If the winch for one line is operated to draw in this line, it closes the clam-shell bucket and hoists it.  During this hoisting, the winch for the other line must also be operated; to pull in the slack.          If this other line is reeled in excessively, it will dump the bucket.  A system is provided for automatic control of the winch being used for slack-takeup, thus avoiding the need for great care and delicate finesse by an experienced hand on a second control lever.  The system puts the slack-takeup winch in hy-draulic series or tandem with the discharge from the hoisting winch, but limits the hydraulic pressure supplied to the slack-takeup winch so that it is barely enough to accomplish the take-up of its line, and cannot cause dumping.
