Abstract: STRUCTURAL ORIENTATION AND PROTECTIVE APPARATUS              FOR TILLAGE ASSEMBLY                   Abstract of the Disclosure A structural orientation and protective apparatus is dis-closed that is particularly useful in a tillage assembly for sod seeding purposes.  The apparatus includes a pair of skids each of which is adjacent to a cutter wheel mounted on the tillage assem-bly for cutting a furrow in ground to be seeded, each skid includ-ing a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel.  Each skid is mounted for pivotal motion about a horizontal axis at the forward end, with the forward end being inclined upwardly from the ground engaging portion.  A vertical mounting plate on each skid has a bracket mounted therebetween at the rear portion to receive a vertical adjustment rod, one portion of which is connected to the frame of the apparatus for controlling the selected depth of furrow to be cut.  A seed tube boot is fastened to the rear portion of the skid so that regardless of the selected depth of furrow cut, the tube remains in the same position relative to the ground.  The particular positioning of the seed boot on the skid, as well as the particular structure of the skid itself, protects the seed boot against foreign objects that could damage or otherwise impair proper functioning of the seed boot.

Abstract: ABSTRACT OF THE DISCLOSURE         A tester for printed circuit board circuits having an elastomeric member on which printed circuit boards are positioned for testing.  When a pressure differential is created across the member, the circuit hoard being tested is moved into contact with electrical leads connected to a computer programmed with respect to the circuits being tested.  The circuit board is supported on the elastomeric member by a thin non-conducting, sealing foam sheet having a cutaway central portion to permit the circuit to make contact with the leads which extend through openings in the elastomeric member and outwardly thereof.          Under the thin  foam is, preferably, a non-conducting sheet of thicker foam, both layers of foam being supported on the elastomeric member, and being movable by the pressure differential to lower the foam layers with respect to the electrical leads and also to lower the circuit board to make contact with the leads.          Means are provided to automatically align the board on the tester and a switch is provided to be actuated by the circuit board to cause the pressure differential to be automatically created when the board is in place.         A multiple unit device for testing any of a plurality of circuit board configurations without rewiring employs a plurality of different sealing foam sheets to mask out all but one of the testing units at any one time.

Abstract: ABSTRACT OF THE DISCLOSURE       An improvement is provided in a procedure for longitudinally seam-welding a pipe-blank for welded steel pipe , from the inside along a cleft or groove by the reverse-polarity GMA welding pro-cess.  Direct electric current is used as the welding current whic is supplied to a consumable welding electrode through a cable as the welding current with the consumable electrode being maintained positive in polarity.  The pipe-blank for welded steel pipe is longitudinally seam welded from the inside along a cleft or groove by feeding the consumable electrode through a welding torch while moving a boom carrying the welding torch through the pipe-blank relative to the pipe-blank in the same direction as that of welding, the boom having a free end which carries the welding torch, and a length at least equal to that of the pipe-blank.  The improvement comprises the steps of:  arranging the cable in the pipe-blank in a predetermined direction; and supply-ing the direct electric welding current in such a direction that the welding current flowing through the cable flows in the same direction  as the direction of welding, thereby substantially preventing the occurence of a magnetic arc blow of the welding arc from the consumable electrode toward the upstream side of the welding direction, i.e., in the opposite direction to that of welding.  The weld thus provided is sound and substantially free from welding defects.

Abstract: REAGENT AND METHOD FOR TBG ASSAY       Abstract of the Disclosure The concentration of thyroxine binding globulin (TBG) in a fluid sample can be determined via radioassay technique with an immunochemical composite comprising anti-TBG antibodies immobilized on a water-insoluble carrier.  The composite is incubated with the sample in a quantity suf-ficient to assure complexation of substantially all TBG in the sample to the antibodies of the composite.  The quantity of TBG completed is determined with radiolabeled thyroxine (T4) which complexes with at least a portion of the complexed TBG.  By separating the labeled composite from the remaining labeled T4, and counting the bound (or unbound) T4, the concentration of TBG can be determined from a standard curve.

Abstract: ABSTRACT OF THE DISCLOSURE         Raster lines are obscured in a photograph of an image displayed on a video monitor.  A photographic film is used as an integrating mechanism.  The TV raster is vertically displaced during the camera shutter open time a total deflection of one horizontal line, thus blending the information between horizontal lines.  Vertical raster deflection is accomplished by adding a series of delays to the normal vertical sync and then generating a processed composite sync to drive the external sync input to the monitor.  The shutter is open for several video frames, each frame being deflected vertically by an integer amount greater than the previous frame until the total raster deflection equals one horizontal line.

Abstract: Applicant:  William E. Whitlock Docket No.  2081-101 For:        Pulse Code Modulated Digital Audio System BRIEF ABSTRACT      The instantaneous amplitude of an analog audio signal is periodically sampled to be converted into multibit binary digital words representing the sampled amplitude.  The bits of successive binary words are reproduced serially with appropriate word and frame synchronising pulses in quarternary coding to pulse code modulate the FM carrier signal used in standard video recording.  The recorded signal is demodulated on playback to reproduce successive digital words that are converted in-to discrete analog values which are low pass filtered to reproduce the original audio signal.  The reproduced digital values are also stored in successive address locations of a random access memory.  Upon detecting data drop-out, such as by monitoring the FM carrier in the reproduced signal, the memory address sequence is reversed to read out the previously entered values backwards, thus approximating the roughly symmetrical waveform envelope of normal high frequency musical signals so as to avoid discernable discontinuity in the audio output.  At the same time, timing pulses are delivered to decrease gradually the bandwidth of the voltage controlled low pass filter to smooth the sample outputs from the memory.  When actual data is reacquired, timing pulses used to increment the memory address gradually restore the maximum bandwidth of the voltage controlled low pass filter.   1.

Abstract: SEALING SYSTEM FOR USE IN COMPOSITE MULTI-STAGE PUMP       Abstract of Disclosure:        A sealing system for use in a composite multi-stage pump or pumps is disclosed which utilizes part of the liquid pressurized by the pump to moderate sealing conditions by introducing said liquid to a portion or portions around the shaft, where the sealing conditions are most critical, and by thus reducing the pressure imposed on the sealing portion make the designing of seals easy.  Also, by introducing pressurized liquid of relatively low temperature to the critical portion(s), minimum flow rate is lowered and thus the operational range of the pump is extended.      When two or more pumps are employed for maintaining continuous operation by alternately switching the working pumps, a flow passage is provided between the pumps so the pressurized liquid from the pump under operation can be introduced to the non-operating pump, thus utilizing the pressurized liquid to prevent liquid kept under pressure in the non-operating pump from leaking therefrom.
