Abstract: ABSTRACT         A free machining cold formable austenitic stainless steel alloy and articles made therefrom which contains in weight percent about   with the balance iron and preferably no more than 2 w/o manganese, 1 w/o silicon, 0.04 w/o phosphorus, 0.08 w/o nitrogen.  Also, the alloy preferably contains 1.4-2.0 w/o copper and the free machining additive is 0.08-0.14 w/o sulfur.                           SPECIFICATION         This invention relates to austenitic stainless steel and, more specifically, to an austenitic stainless steel having a unique combination of good cold formability and machinability It has long been recognized that austenitic chromium-nickel stainless steels not only have generally poor cold work-ability, but they are also characterized by wide variations in how they respond to cold forming.  Bloom et al, 39 ASM 843-867 (1947), demonstrated that increasing carbon from about 0.03% by as little as 0.01% sharply increased the cold work hardening rate of 18Cr-8Ni stainless until about 0.10% carbon content was reached.  They also brought out that increasing nickel from 8% to 12% effectively rendered the steel insensitive to increases in carbon content insofar as cold work hardening was concerned.         U.S. patent No. 2,697,035, granted December 14, 1954 to W. C. Clarke, Jr., relates to free machining austenitic chromium-nickel stainless steel containing 12-20% chromium, 6.5-15% nickel, 1 to about 5.0% copper, 0.1-0.5% sulfur and/or selenium, up to 0.5% phosphorus and the remainder iron.  When Clarke characterizes his alloy in claim 4 as having an improved surface finish, the just-mentioned composition is restricted to a range of 2.5 to about 5.0% copper.  The alloys disclosed by Clarke in the tablet Col. 3, have left much to be desired both with regard to their cold working properties and machinability as represented by surface finish.          The present invention is based upon the discovery that a unique combination of cold formability and machinability

Abstract: SEGMENTED EXTENDIBLE BOOM                            Abstract A longitudinally extendible, segmented boom structure includes a plurality of hollow, substantially V-shaped segments (10) which are pivotally connected to adjacent segments for storage.  A series of load-bearing cables (134) extend through the segments for carrying loads.  The segments have uniform cross-sections and progressively increasing lengths.  Segments are stored in rolled-up form on a reel (12) by pivoting the segments to form a coil of nesting segments.  Each segment has laterally extending side flanges (108) through which longitudi-nally extend the pre-tensioned load-bearing cables.  The cables pass through the flanges on opposite sides of the boom segments for supporting vertical loads and resisting side loads on the boom.  A second set of auxiliary cables (79) on the underside of the boom is automatically payed out as the boom is extended. The auxiliary cables prevent the extended segments from col-lapsing when inverted.  The center point of the segment reel is adjusted in elevation to automatically feed boom segments at an optimum angle into a segment dispenser and boom support structure which has rollers thereupon for cooperating with corresponding lands and grooves on the segment flanges.

Abstract: PROCESS FOR THE FORMATION OF IMAGES    ABSTRACT      A layer of a photoresist composition on a substrate is exposed imagewise to actinic radiation, as through a negative, the photoresist composition comprising an epoxide resin, a benzenoid polyamine, and an aromatic compound which liberates an acid on exposure to actinic radiation.  The composition is then heated such that where the radiation has struck the composition local curing of the epoxide resin takes place, the liberated acid acting as accelerator in the curing by the benzenoid polyamine. In parts not struck by radiation the acid accelerator is not liberated and so curing (and insolubilisation of the epoxide resin in solvents) takes place much more slowly.  By treatment with a suitable solvent unirradiated (and hence uncured) portions of the compositions are dissolved away, an image being formed on the substrate.

The device comprises a shell, a plug assembly carried by the shell.  The plug assembly is capable of mating engagement with other electrical contacts and has receiving means for receiving electrical conductors.  A single fastener holds the terminals of the conductors in electrical connection with the electrical contacts.          The single fastener includes a movable carriage on which is mounted a nut through which a screw is threaded with a head with a flange that is engaged with the wall of the plug assembly so that when the screw is rotated, the carriage moves so as to decrease or enlarge a chamber in which the conductor terminals and a portion of the electrical contacts are situated.

Abstract: ERROR CORRECTION SYSTEM            Abstract of the Disclosure A method and apparatus for correcting single bit errors in a data word stored in a first memory device without requiring the data word to include an error correction code includes a multi-stage dynamic shift register for dividing a data word by a polynomial during the time the data word is being written into the first memory device resulting in the generation of a remainder which is stored in a second memory device. When reading the data word from the first memory device, the data word is again divided by the same polynomial. The remainder generated by the second division is com-pared with the remainder stored in the second memory device.  If the remainders do not match, indicating an error was introduced into the data word during storage or retrieval of the data word in the first memory de-vice, the remainder stored in the second memory device is shifted into the dynamic shift register and followed by the shifting of a number of zero bits into the shift register which is equal to the maximum number of bits in the data word located in the second memory device.  As each zero bit is shifted into the shift register, a bit counter is incremented and the output bit of each stage of the shift register is examined.  When the output of all the stages in the shift register except the last stage is zero and the last stage contains a binary bit one, the count of the bit counter points to the bit location in the data word stored in the second memory device locating the bit that is in error. The binary bit at this bit location is then complemented, thereby correcting the error bit in the data word.

Abstract: ABSTRACT  SURVEILLANCE SYSTEM FOR CURVED CONTINUOUS CASTING PLANTS        A system is provided for limiting the parameters of the motion of a billet in a bow-type continuous casting plant. The stiffness of the billet is determined from values of the motion of the elements of the billet and/or from properties of the advancing billet as picked up by sensing elements. The determined values are compared with preset limiting values for parameters such as the maximum residual withdrawal time, the maximum still permissible stoppage time period and/or the permissible minimum withdrawal speed.  If the limiting values are exceeded  a signal is provided by a computing provision and fed to an alarm or  is used to trigger a shut-off of the continuous casting process.

Abstract: ABSTRACT OF THE DISCLOSURE         A composite FM stereo multiplex signal is demodulated using a double-balanced switching circuit cooperating with current mirror circuits so that demodulation and separation of the multiplexed signals occurs in the current domain.  The switching circuit receives a switching signal that is a sub-carrier frequency of the FM stereo multiplex carrier signal, and the switching circuit is provided with the composite stereo signal as a output current signal from a first current mirror circuit.          Outputs from the switching circuit are then fed to respective left and right channel current mirror circuits where the current output signals therefrom are subtracted in respective current difference circuits from the composite current output signal produced by the first current mirror circuit, thereby producing left and right channel stereo signals having predetermined separation and signal-to-noise ratio.
