Abstract: ABSTRACT OF THE DISCLOSURE        A method of forming a torsion bar wherein steel, preferably an alloy steel of medium carbon content, is formed in the desired size and shape and is through hardened for providing a desired core hardness.  The case of the bar is  then hardened for transforming austenite in the case into martensite causing the case to expand thereby inducing high compressive stresses near the surface with the com-pressive stress decreasing radially inward of the surface.      The core of the bar is retained below lower transformation temperature for resisting expansion of the case thereby inducing hoop and axial compressive stresses and radial tensile stressed in the case.  The hardened bar is then cold worked by twisting and releasing the bar at least twice for applying a torsional stress in the angular direction of the bar loading which presents the bar by twisting it beyond its initial yield strength for redistributing the stresses and inducing a residual torsional stresses therein in a direction opposite to the reset direction.     A torsion bar formed by the method of the present invention is also disclosed.                            -1a-

Abstract: METHOD AND APPARATUS FOR THE WET DESANDING AND CLEANING OF CAST PIECES               ABSTRACT OF THE DISCLOSURE    In a hydro jet housing the form block, possibly with core, is stripped of mold sand by means of a high-pressure water jet.  The sand is fed in the form of a muddy pulp to a first hydrocyclone, where the water is largely separated and is supplied for the formation of new muddy pulp.  The sand flows into a scrubbing mechanism for knocking off its binding material, which has settled as a coat around the sand grains.  After this again a muddy pulp is prepared in the intermediate container, which for the hydro-extraction of the water with the coating particles therein is fed to a second hydrocyclone.  The sand is then dried and cooled and is available for further use.  The contaminated water is neutralized with flue gas, after which a flocculation means is added to it and the cleaning takes place in a settling tank and possibly in a filter.      The apparatus permits an economical operation, in that both the sand and also the water are being claimed in a closed cycle.

Abstract: ABSTRACT A turret mounted series of photocomposing disc fonts wherein the turret has a series of disc hubs all having a different elevation in order that the disc members may be bunched together in overlapped relationship and hence occupy a minimum area within the photocomposing machine.  The turret is rotated to select a particular disc for insertion into an optical system, and is advanced or retracted along its own axis according to the elevation of the particular hub selected in order that the optical system of a photocomposing machine may remain stationary, and the particular disc member be brought to the proper focus position within the optical system.  The advance in the art is primarily in the placement of the discs in overlap relationship and then advancing or retracting the turret in order to accomplish proper positioning of the disc as opposed to the concept of the prior art in keeping all discs on one plane and then rotating the turret to bring each disc in turn into the optical system.

Abstract: SAFETY DESCENT DEVICE            ABSTRACT OF THE DISCLOSURE     A fall prevention safety device for attachment to a harness worn by a workman for providing a safely controlled descension rate from an elevated structure includes a cable having one end connected to the harness and strung around a double pulley system having an upper pulley mounted to the elevated structure and a lower pulley mounted to the upper end of a vertically reciprocal plunger which falls substantially unimpeded into a hydraulic cylinder. The cylinder substantially resists upward withdrawal of the plunger.  The other cable end is connected to the upper pulley yoke such that during ascent of the workman up the structure, the lower pulley and plunger move downwardly and take up cable slack. If the workman slips and falls at any point during ascent, the cable immediately and automatically provides descension at a controlled rate determined by the resisted withdrawal rate of the plunger as the cable now pulls the lower pulley upward.  The hydraulic cylinder includes a bypass line with ports communicating with the hydraulic cylinder at upper and lower compartments above and below the inner plunger end having a seal therearound defining the two compartments. The inner plunger end also carries a one-way valve which is in an open condition during downward plunger movement and is closed by fluid pressure upon initiation of workman descent.

Abstract: Gitlin-6 36. TIMING ACQUISITION IN VOICEBAND DATA SETS             Abstract of the Disclosure In a multipoint data communication system using quadrature-amplitude modulation, a master modem (20) and a plurality of tributary modems (11a, 11b...11n) are interconnected via respective transmission channels (13a, 13b... 13n, 16).  Adaptive equalizer circuitry (55, 56) in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary.  The tap coefficient ensembles for each tributary are stored in a memory (91) from which they are retrieved at the start of transmission from that tributary.          Timing-acquisition circuitry (29) within the master modem adjusts the phase of the latter's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points.  In particular, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary.  The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisition equalizer outputs.  The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of two successive ones of the timing acquisition equalizer outputs.  The timing acquisition signal is illustratively a double-dotting pattern having a four-symbol-interval period.  That period is integrally related to the carrier frequency.  This allows the samples needed in order to begin forming the timing acquisition equalizer outputs to be generated by replicating the samples taken over only four symbol intervals.

Abstract: METHOD AND APPARATUS FOR THE   IDENTIFICATION OF OBJECTS                   ABSTRACT OF THE DISCLOSURE Disclosed is a system for identifying objects appearing on an image window and bearing on a surface facing the window an identification in the form of a data field which includes at least one data track bearing contrasting symbols and a plurality of contrasting line patterns which identify the position and orientation of the data track.  The window is optoelectronically scanned in a parallel line raster to generate a video signal which corresponds to the scanned contrast sequence appearing at the window. The con-trasting line patterns are initially identified in a sta-tionary detection raster and the angular inclination of the raster lines relative to the contrasting line pattern is determined.  Thereafter, the symbols in the data track are read in a reading raster having relatively narrowly spaced raster lines by electronically rotating the reading raster through the intersection angle between the previously detected contrasting line pattern and the detection scan lines so that the reading scan lines are parallel to the data track. Thereafter, the data track is scanned and the symbols therein are decoded and further used.
