Abstract: 1,250,013. Electrolytically coating steel with Cr and chromium oxide; lead alloy. UNITED STATES STEEL CORP. Oct.10, 1968 [Nov.3, 1967], No.48151/68. Heading C7A and C7B. Can stock is produced by electrolytically coating steel with both Cr and overlying chromium oxide. The process comprises (a) providing a first stock-treating zone including an electrolyte containing from 40-100 g/1 of chromium trioxide and also containing sulphate ions (and optionally fluoride ions), the electrolyte being effective, under the influence of an electric current, to deposit metallic Cr and a hydrated, trivalent Cr-containing oxide upon stock as a cathode and capable of chemically dissolving the oxide; (b) continuously moving a cleaned, elongated, flat rolled steel stock article as cathode through the first zone while applying to the article a current of at least 500 amps/sq ft of cathode surface for a time sufficient to electro-chemically deposit a continuous layer of metallic Cr of a weight of at least 1.5 mg/sq ft of article surface together with an overlying chromium oxide film; (c) continuously passing the article from the first zone into and through a second stock-treating zone containing said electrolyte; and (d) applying electric current to the article as cathode in the second zone of zero or less than 212 amps/sq ft of cathode surface to provide on the final, Cr-plated article a continuous oxide film overlying the metallic Cr layer and containing 0.5 to 2.0 mg of trivalent Cr per sq ft of article surface. The sulphate ions may be contributed by H 2  SO 4  or chromium sulphate and the fluoride ions by HF or a silicofluoride. The steel may be strip moving at 200-1000 feet/min. For the electrolysis, the counter electrodes may be Pb-1% Ag alloy. Before the Cr and chromium oxide coating treatment, the steel may be cleaned by electrolytic alkali treatment and be electrolytically pickled. Following the chromium oxide coating treatment, the steel may be coated with a clear epoxy phenolic enamel.

Abstract: 1,262,178. Gear cutting machines. GLEASON WORKS. 1 Oct., 1969 [1 Oct., 1968 (3)], No. 48238/69. Heading B3K. [Also in Division F2] The cradle 14 of a bevel gear cutting machine is supported for axial movement within its housing 12 in predetermined time relation to the rotational movements of the cradle and work spindle. Rotational drive to the cradle is through an axially fixed gear 44 and drive pins 100, the cradle being capable of axial movement on the pins by means of bearings 102. Hydraulic cylinders 108 with pistons 106, mounted for rotation with the gear 44 normally urge the cradle in a direction towards the workpiece. A yoke and shoe arrangement 50, 54, 52 at the rear end of the cradle carries an eccentric rod 64 forming part of a crank mechanism 58 angular movement of which effects axial movement of the cradle. Rapid retraction of the cradle e.g. for indexing of the work is effected by a feed cam   65 (Fig. 4) connected via follower 67, lever 70, adjustable tie rod 74, 78 to the crank mechanism 58. A secondary cam surface 130 fixed to the cam 65 operates hydraulic control valve 120 to effect rapid release of hydraulic pressure from the cylinders 108 when this rapid retraction takes place. Axial movement of the cradle, particularly for and during finish cutting operations, may also be effected by a helical motion cam 150 (Fig. 6), which is driven through a suitable train of gearing from a gear 134 affixed to the cradle drive gear 44. The cam 150 drives a linearly movable follower 152 which in turn drives an eccentric 158 connected to the crank mechanism 58. The helical motion mechanism operates to move the cradle axially when the cam 65 and its follower are on a dwell portion 90 and operates against the action of the hydraulic cylinders and pistons 108, 106. Drive to the cutter in the cradle is conventional and includes a splined telescoping portion 38. Hydrostatic bearings (see Division F2) support the main cylindrical portion of the cradle in the housing 12. The cradle is adjustably balanced by means of balance weights 204 received in a series of pockets 200 around the cradle periphery the numbers of weights in the pockets being manually alterable.

Abstract: 1,199,989. Analogue-to-digital converters. FUJITSU Ltd. 3 Nov., 1967 [4 Nov., 1966], No. 50207/67. Heading G4H. An analogue to digital converter comprises a number of circuit stages connected in cascade, each stage (in the case of a binary coder) having means for determining the polarity of the input signal and means for applying a bias signal of opposite polarity to a summing circuit together with the input signal, the resulting signal being multiplied by two before passing to the next stage. In the form of Fig. 2 the input signal at IN is applied to a zero comparator COMP which gives a positive or negative output according to the polarity of the signal. A pulse generator PA translates this into a " 1 " or " 0 " output digit. Trigger FF is set or not by the output from COMP and controls inverter UP to invert the reference voltage V only if the input at IN is positive. The input signal, suitably delayed at DL, is applied with the bias of opposite polarity to a summing circuit SA. The sum is amplified at AMP so that the total amplification of the modified input signal is two. The reference voltage source may be stabilized by a Zener diode kept at constant temperature. There may alternatively be separate positive and negative sources one of which is switched to the summing circuit by electronic or electromechanical switches. In another modification there are two sources, one being permanently connected and the other, of opposite polarity and twice as large, being connected by a switch. In another form, Fig. 7, the input signal is applied to a saturated amplifier which, if the input is positive gives a negative reference voltage of half the maximum signal, and if the input is negative gives a corresponding positive reference voltage. This is applied to a pulse generator PA to give binary digits, and a summing circuit SA to be added to the delayed input as before. The individual circuits are described and a form giving a conversion in ternary code is described.
