Abstract: METHOD OF CONSTRUCTION UNDERGROUND CONCRETE   WALLS AND REINFORCEMENT CAGE THEREFOR                 ABSTRACT OF THE DISCLOSURE           There is disclosed an improved method of constructing an underground reinforced concrete wall utilizing the slurry trench excavation method.  According to the invention, at least a pair of spaced elongated primary excavations each adapted to receive a pair of H-beams rigidly joined together by steel lattice work; and a rebar cage.  The channel or space in each H-beam at the outer channel between the flange and webs is filled with a polystyrene foam attached to the cage by steel plates and angles.  These elements are lowered into the primary excavations and concrete is poured therein filling the spaces in the excavations and displacing any bentonite slurry from the trench to form primary wall elements.  Thereafter, intermediate excavations are performed between the concreted sections and the H-beam portions thereof, the polystyrene foam being easily removed from the outer channel and the H-beam channel with the flanges thereof serving as guide elements for the excavating tool.  According to a preferred procedure, the spaces between the first two primary wall panels have a length at least equal to a multiple greater than one of the primary wall panel ex-cavations for secondary wall elements to be formed in the intermediate space.  In this way, the same excavating tool can be used for forming equally spaced elements and the ex-cavating tool will not in any way be impeded by engagement with steel H-beams since at least one end of the tool will be free to bite into earth or the space of an adjacent excavation.   In order to form a reinforced excavation around and below under-ground utilities, and other obstructions, the earth between the two previous excavations is excavated, two beams are placed on either side of the utility or obstruction and the intervening excavation panel is cast with concrete without the use of a reinforcing cage or is cast using a steel fiber reinforced concrete in place of the reinforcing, is inserted to thereby form a reinforced wall in combination with the H-beam.  There is also disclosed a novel method and apparatus for reducing wall thickness and decorating and improving surface finish of cast-in-situ underground concrete walls.

Abstract: ABSTRACT OF THE DISCLOSURE A water-soluble, injectable cross-linked orgotein having a molecular weight of up to 500,000 is provided herein. The orgotein molecule is intermolecularly cross-linked by at least one organic bridging group with at least one molecule of a water-soluble, injectable non-antigenic protein.  The organic bridging group is formed by the reaction of orgotein or a mixture of orgotein and another water-soluble, injectable non-antigenic protein, with an organic difunctional cross-linking agent. This novel cross-linked orgotein has a substantially longer half-life in the blood after injection than orgotein.

Abstract: TANK-TYPE OIL CIRCUIT-INTERRUPTER WITH JET FORCES COUNTERBALANCING      THE MAGNETIC FORCES                    ABSTRACT OF THE DISCLOSURE         A tank-type oil circuit-breaker has a pair of arc-extinguishing grid-structures disposed interiorly within the oil tank, each of said arc-extinguishing grid-structures having a pair of outwardly-directed horizon-tally-laterally-spaced venting ports, with the angular direction, or divergence between the two horizontally-spaced venting ports of somewhat critical angular magnitude.    The construction is such that the two spaced venting ports on each arc-extinguishing grid structure collectively produce a resultant inward G-directed jet force, which substantially counterbalances the outwardly-directed magnetic and mechanical forces resulting from the U-shaped line-current flow passing through the circuit-interrupter.         The angular separation, or angular divergence provided between the two horizontally-laterally-spaced venting ports of each arc-extinguishing grid-structure falls within the range of angular magnitude of 80° to 160°.  A desirable divergence range is between 100° and 140°, and preferably, the angular divergence is desirably 120 angular degrees.

Abstract: ABSTRACT OF THE DISCLOSURE A TV monitor includes an antenna coupler capable of selectively coupling the TV receiver being monitored to an antenna or an r.f. oscillator. The oscillator is selectively operated to impose an r.f. signal onto the antenna input of the receiver between successive horizontal blanking periods on an active video line.  One probe, connected to the horizontal retrace circuit of the receiver monitors the receiver for an "on" or "off" condition, while another probe, connected to the kinescope circuits of the receiver detects the channel to which the receiver is tuned.  By successively stepping the r.f. oscillator through successive frequencies within the bandwidth of individual channels, and by monitoring the kinescope probe for that frequency which compares to that generated, channel identification may be determined. A plurality of individual monitors may be utilized with individual receivers within a household and the data may be collected and stored in a household collector for eventual transmission to a central station.
