Abstract: ABSTRACT OF THE DISCLOSURE         In an apparatus for automatically maintaining a transducing head assembly on the proper track, which is particularly adapted for a helical scan recording and/or reproducing apparatus capable of providing special motion effects, track selection method and apparatus is disclosed.          The apparatus is of the type which utilizes transverse positioning of the transducing head to accurately follow a track during reproducing and, at the completion of the track, to properly position the head in position to either play the next adjacent succcessive track, replay the same track or play another track so that the appropriate special motion effect is achieved.  During the accelera-tion of the tape to normal speed, the tape transport is initially controlled relative to a recorded control track to position the head relative to the recorded tracks so that the reproduced video signal is color framed with respect to studio reference.  Verification of color framing is performed after reaching normal speed by detecting the H sync to V sync phase relationship of the reproduced video signal and deflecting the movable head 1 track position along the tape to obtain proper color frame conditions if initial color framing was incorrect.

Abstract: ABSTRACT LDH1 levels in serum samples can be rapidly and accurately assayed by a novel immunochemical technique. In such procedure the serum sample is treated with soluble antibodies against the M subunit and the resulting antigen-antibody reaction product is insolubilized with a second antibody supported on an insoluble material. The resulting supernatant containing only LDH, isoenzyme is assayed for enzymatic activity by conventional procedures. The assay of LDH1 levels in sera is useful in determining whether the subject has undergone a myocardial infarction.

Abstract: ABSTRACT     A computer based railway interlocking control system, preferably of the parallel redundant type (Fig. 2) in order to provide enhanced reliability as compared to a single computer system.  The railway traffic control devices, e.g. points and signals, are arranged to be controlled by signals in one of two possible steady states, the interlocking control means (30, 31, 32, Fig. 2) is arranged to produce control signals in the steady state for de-energrised or "safe" device settings and in an alternating state for energised or potentially "unsafe" settings.          The alternating control signals (33, 34, 35 or 38) must be converted to the corresponding steady state to operate the devices thus, the converting or restoring circuit discriminates against dormant wrong side failures, i.e. "unsafe" signals to increase the inherent safety of the system.

Abstract: Abstract of the Disclosure Fire-fighting foam effective against burning hydrophilic or polar liquids like lower alcohols, ketones, etc. is made from concentrate containing thixotropic thickener dissolved in large amount, up to 1.5% or more, yet has a tolerable viscosity so that it can be poured or pumped.  Heteropolysaccharide-7 or chain-shortened modifications of it are particularly suitable for this purpose.  Higher concentrations are made practical by including in the concentrate urea, thiourea, ammonium cyanate or ammonium thiocyanate, to reduce the concentrate's viscosity and keep the polysaccharide from separating out upon freezing.  Magnesium salts can also be dissolved in concentrate to improve fire extinguishing action when diluted with fresh water.

A resilient coping strip embraces the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration. Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, extend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron.  Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation.  After back-filling and forming the apron, those bars are removed.
