Abstract: A B S T R A C T           Apparatus and controls therefor are provided for piercing sheet material.  A punch is driven by a cylinder and piston positioned in tandem with a second cylinder and piston. The arrangement is such that a small pressure applied to the second piston results in a large force applied by the punch to the sheet material.  Controls for the apparatus include means to sense a sudden drop in pressure in the second cylinder and means to then supply return air to the rod ends of the cylinders The controls are quickly responsive so that as the punch breaks through the sheet material, it is immediately reversed toward its original position.  The noise and jarring ordinarily resulting when a punch breaks through sheet material being pierced are thereby substantially eliminated.

Title: Apparatus for determining steering positions  of the front wheels of a vehicle
Inventor: LILL MELVIN H
IPC: B62D17/00
Filed: 1978-08-16
Granted: 1982-05-18
Abstract: ABSTRACT OF THE DISCLOSURE          An electro-optical apparatus for determining, during caster angle measurement procedures, when the front wheels of a vehicle have been turned into a first desired steering position oriented in one rotative direction from a "straight-ahead" position and have thereafter been turned to a second desired steering posi-tion oriented in the opposite rotative direction from the "straight-ahead" position.  A multiple light beam projector and a photosensitive detector are mounted to a front wheel of the vehicle for rotation therewith, and a reflector is mounted to the rear wheel of the vehicle which is on the same side of the vehicle as the projector and detector.  The projector rearwardly projects three directional beam patterns with each pattern consisting of sequentially emitted discrete beams which are projected at unique angles with respect to the plane of the front wheel.  One beam pattern lies in a plane generally parallel to that of the front wheel, and the other two beam patterns are equiangularly displaced to each side of the plane of said one beam pattern, such equiangular dis-placements being equal to the preselected turn angles for making the caster angle measurements.  The reflector is oriented parallel to the rear axle of the vehicle to direct a projected beam pattern so as to intersect the detector when the beam pattern is generally parallel to the plane of the rear wheel.  The beam patterns generally provide toe angle information for the front wheel, and circuitry is provided for processing the output signals of the photosensitive detector when receiving said one -1a-beam pattern to indicate, by means of a particular output signal condition, the desired "straight-ahead" position for the front wheel. By repeating said output signal condition when the front wheel is turned to expose the other beam patterns to the detector, the exact pre-selected turn angles are readily obtained.     -1b-

Abstract: "BENEFICIATION PROCESS FOR OXIDIZED IRON ORE"           ABSTRACT OF THE DISCLOSURE A chlorine source is provided in a reactor in combination with a ground oxidized ore and a particulate carbonaceous reductant.  The amount of chlorine provided is significantly less than the stoichiometric requirements for reaction with the total iron content of the ore; the amount of the reductant is greater than that required to effect the reduction of the total iron content of the ore.  The reactor is operative to retain the reaction gases in intimate contact with the feedstock mixture without significant dilution of said gases in order to provide a reducing atmosphere.  The mixture is indirectly heated to a temperature below 950°C, preferably in the range 700 - 950°C, and the mixture is retained in the reactor for a period of time sufficient to cause the major portion of the iron to be transported  out of the ore and to be deposited on or near the solid reductant and form discrete metal particles.  These particles can be separated from the gangue minerals, for example by magnetic separation, to provide a high yield - high quality iron concentrate.

Abstract: ABSTRACT OF THE DISCLOSURE         A digital device for determining a steady-state value of the analogue signal comprises an analog-to-digital converter for converting the analogue signal into a numerical pulse code connected through a synchronization unit to inputs of threshold counters, a clock pulse generator connected through a synchroni-zation unit to the inputs of the threshold counters and to inputs of a time interval discriminator and through a frequency halver to the inputs of a reversible counter, and a digital display unit connected to digital outputs of the reversible counter.          The device also comprises decoders of zero state of the threshold counters, having their inputs connected to the respective thres-hold counters and their outputs connected to subtract count block-ing inputs of the respective threshold counters to the inputs of the reversible counter and to a control input of the digital display unit.  Overflow inputs of the threshold counters are connected to initial setting inputs of the time interval dis-criminator.  An information output of the time interval dis-criminator is electrically connected to the input thereof and to the inputs of the threshold counters to those of the reversible counter, and to the control input of the digital display unit. In addition, the device includes seven AND circuits and three NOT circuits by means of which logical control of electric communi-cation between the units of the device is effected.  The fore-going design of the device permits the steady-state value of the analogue signal to be determined more accurately.  In the device an error in determining the steady-state value depends exclusively on the resolution ability of the analog-to-digital converter and not on the level of noise.  The use of simple elements and units of the digital-computing technique in the device ensures  high reliability, low cost and small dimensions.

Abstract: ELECTROPLATING ALUMINUM                  Abstract of the Disclosure In a process for electroplating aluminum articles, the article is first electrolytically treated, as anode, in a bath consisting essentially of a solution of caustic alkali, and thereafter electroplated.  The electrolytic caustic cleaning step, preferably involving agitation, is found specially suitable in composition and indeed is effective in a relatively short time to afford an essentially bare aluminum surface, i.e., free of anodic oxide film and also free of pitting or smut, for advantage in plating, as with tin or other metal.  Intermediate steps can be employed such as immersion tinning or zincating and brief electroplating such as a bronze strike; the electrolytic cleaning co-acts well with the intermediate stages, indeed requiring fewer steps over all.  Although applicable batchwise, the process is particularly appropriate for continuous electroplating wherein the aluminum wire or strip may pass rapidly through the electrolytic cleaning, intermediate and plating baths in succession.
