Title: Precast concrete structural unit and composite  wall structure
Inventor: TOFFOLON ROGER L
IPC: E04B2/02

Abstract: IMPROVED PRECAST CONCRETE STRUCTURAL   UNIT AND COMPOSITE WALL STRUCTURE               ABSTRACT OF THE DISCLOSURE           Precast concrete structural units and a composite wall structure comprising a plurality of the units stacked vertically in staggered horizontal rows.  Each unit com-prises a pair of laterally spaced longitudinally extending side panels.  A pair of laterally extending connecting arms are formed integrally with the panels at their respective inner surfaces whereby to secure the panels in relatively fixed position.  A mortise-tendon connection between super-posed units is provided for with a vertically recessed mortise at the bottom of each connecting arm and a comple-mentary vertically projecting tendon at the top of each arm.  Each of the mortises and tendons defines a pair of laterally spaced oppositely facing generally vertical bearing surfaces and each mortise and tendon is approxi-mately 1/3 the total width of the associated structural unit.  Longitudinal spacing of the connecting arms from each other is approximately twice the longitudinal spacing of each arm from the adjacent end of the side panels. Thus the units may be stacked vertically in horizontally staggered rows with horizontal displacement between units in adjacent rows approximately one half the length of a unit.  The connecting arms are thus aligned vertically to provide columnar openings which may be filled for added structural integrity of a composite wall.  A composite wall may include rows of wider units at the bottom with rows of narrow units thereabove and conversion units may be employ-ed at the interface between wider and narrower units.  A     bearing wall may include vertical tie rods for rows of wider units with foundation slabs therebeneath and beam slabs thereabove.  A bearing slab may also be employed atop narrower upper units.  Bearing material may be emplo-yed in joints between units and a filter and trim material may be employed in bearing and other walls.  A shingle effect may also be provided to conceal horizontal joint lines.

Abstract: STATIC INSTANTANEOUS OVERCURRENT RELAY WITH   LOW TRANSIENT OVERREACH               ABSTRACT OF THE DISCLOSURE A static instantaneous overcurrent relay with reduced transient overreach is provided for use in protecting an a-c power line from overcurrents.  The relay operates on an input signal representative of the magnitude of the current in the a-c power line and develops a relay output signal when the magnitude of the current reaches a predetermined magnitude.  In a preferred embodiment, the relay includes a level detector circuit for receiving the input signal which is in the form of a pulsating waveform having the same frequency as the a-c power line.  The level detector circuit develops a discrete level detector output signal in response to each pulse of the waveform which attains a magnitude representative of the predetermined magnitude.  Output circuit means is coupled to receive the discrete level detector output signals and includes temporary inhibit means for inhibiting the development of the relay output signal until the output circuit has received two of the discrete level detector signals.  In one form of the invention, the temporary inhibit means includes delay circuit means for receiving the discrete level detector output signals and developing a delayed signal.  AND circuit means is then provided to receive the discrete level detector output signals and the delayed signal resulting in a relay output signal after two level detector output signals are present.  In one form of the present invention, the relay has a transient overreach percentage of less than 8% for power line angles up to 75°.  The relay of the present invention may be employed in connection with a  single phase input signal as well as with a three phase input signal.

Abstract: HOPPER DEVICE FOR MATERIAL SPREADER HAVING         A MULTI-POSITIONABLE COVER Abstract of the Disclosure A device for spreading particulate material from a vehicle mounted dump bed includes a hopper device mounted transversely across a material discharge end of the dump bed and a broadcast spreader beneath one end of the hopper device.  The hopper device includes first and second spaced end walls, a fixed back wall between the end walls, and an elongated auger extending between the end walls arranged to be rotated about an axis parallel to the back wall.  Rotation of the auger causes particulate material entering the hopper device to be moved toward one end wall beneath which the broadcast spreader is located.  Spreading through, dumping over, and cleaning of the hopper device are possible as a result  of an independent cover member extending between the end walls and movable between three corresponding positions.  Support of the cover member relative to the hopper device is provided by a series of latching pins through each of the end walls and into por-tions of the cover member with one pin connection allow-ing movement of the cover member into a generally upstand-ing position for cleaning of the hopper device.

Abstract: Abstract of the Disclosure The surfaces of metal workpieces being welded are fused while feeding the workpieces towards each other at a constant speed, and the feeding speed is before the upsetting increased to a final value for a period of (1.0 to 4-0)   where .DELTA.max is the maximum gap between the workpiece surfaces being welded and v1 is the average workpiece feeding speed over the period of its increase.  Empirical formulas are presented to determine the maximum gap for workpieces of various thicknesses.  The period of feeding the workpieces at the final feeding speed, determined as described above, allows welding workpieces of more than 5 mm in thickness with relative large areas of the surfaces being joined.          The method of the invention is useful in constructing pipelines, weld-joining off-size blanks in rolling, and manufacturing various metal structures from rolled products.

Abstract: Abstract:        A furnace air volume control apparatus for controlling the volume of furnace  air to achieve efficient burning is disclosed.  The apparatus includes regulating valves positioned within supply air inlets and exhaust gas outlets of the furnace.  A measured data receiver positioned on the exhaust gas side transmits a measuring signal to a control unit connected to the regulating valves.  The control unit includes a storage unit for storing valve positions assigned to respective burner loads.  By monitoring various exhaust gas parameters with the measured data receiver and control unit valve position,adjustment in response to changes in the burner load is possible by comparing a previously stored valve position recalled from the storage unit with a characteristic curve.  The valve adjusting value stored in the storage unit is essentially congruent with the change in burner load.  After exhaust gas stabilization has occurred in response to different burner loads precise correction of the valve position value occurs.
