Abstract: BUILDING CONSTRUCTION          Abstract A square or rectangular concrete floor slab is first formed, although other shapes, such as circular, are also envisaged.  A reinforced concrete column extends vertically upwardly from a generally central location on the floor slab.          A separate reinforced concrete structure of basically the same outline as the floor slab and destined to become the roof, is constructed on the floor slab with the aid of a shaping and smoothing screed mounted on the column to rotate about a vertical axis.  This latter structure is elevated by means of lifting devices temporarily mounted on the top of the column.          With the roof thus suspended, additional concrete is poured into a form that has been placed around  and outwardly displaced from the column.  The result is the format on of an expanded column that defines an upwardly facing peripheral shoulder on which the roof rests when the lifting force is removed.  The screed is designed to be of variable length, e.g. by a hinged or telescopic end, to enable two such buildings to be constructed contiguously without the screed from one interfering with the other.  A ceiling layer, including insulation, can be laid on the floor slab when the roof structure is being poured so as to be bounded thereto and thus provide a preformed ceiling when the roof is hoisted into place.

Abstract: BUFFER MEMORY CONTROL CIRCUIT                 FOR LABEL SCANNING SYSTEM                         Abstract A scanning system includes a pair of buffer memories for alternately accumulating strings of signals which may contain bar coded label data.  Candidate selection logic circuits examine incoming signals to generate a candidate signal when a string of signals satisfies gross logical tests.  A control counter responds to the incoming sig-nals and to the candidate signal to select an alternate buffer memory only when the active memory is fully loaded and contains at least part of a label candidate.  The contents of the fully loaded memory are transferred to a processor for further analysis while incoming signals are routed to the alternate memory.

Abstract: METHOD OF IMPARTING COLOR HIGHLIGHTS OR SHADOWS        TO A TEXTURED DECORATIVE LAMINATE          Abstract of the Disclosure A contrasting color is imparted to the decorative surface of a decorative laminate by inserting a pigment coated release sheet between the molding caul and the decorative surface during the molding operation, with the pigment facing the decorative surface.  Upon application of heat and pressure during the formation of the laminate, color is transferred from the release sheet to the decorative surface.  A suitable technique is also used to emboss or impart surface texture to the decorative surface during molding.  Thereafter, the textured surface is subjected to rubbing or brushing to remove more color from the embossed or raised areas than the debossed areas, thereby highlighting or imparting a shaded effect to the textured surface.

Abstract: ABSTRACT     A knee brace comprises generally U-shaped upper and lower support members for fitting around the upper and lower leg above and below the knee joint, two pairs of upper and lower support arms extending downwardly and upwardly, respectively, from the upper and lower support members along opposite sides of the patient's upper leg, and polycentric hinges for pivoting the upper support arms to the lower support arms adjacent lateral and medial sides of the knee joint.  Floating condyle pads are affixed to fixed inside portions of the polycentric hinges.  The condyle pads are held in direct contact with the lateral and medial sides of the patient's knee joint.  The condyle pads are restrained from rotational movement but are hinged so they can pivot toward or away from each other about common generally vertical axes within the space between the polycentric hinges.  The condyle pads can be spring-biased inwardly by their hinges for contact with opposite sides of the knee joint during swinging movement of the upper and lower leg about a horizontal axis.  Flexible and longitudinally elastic upper and lower straps are releasably secured to the upper and lower limb support members.  The straps extend in opposite directions away from the sides of the upper and lower support members.  This provides a de-rotation strapping system which inhibits twisting of the lower leg relative to the upper leg about a vertical axis.
