Title: Metal analysis for acid-soluble elements
Inventor: KELLY JOHN H
IPC: G01N33/20
Filed: 1983-11-01
Granted: 1984-12-04
Abstract: 23 Wet chemical, microcomputer-controlled procedure for the rapid dissolution of metal followed by accurate determination of elements in the sample and, more specifically, suited to meet steel industry requirements for control of the level of acid-soluble aluminum in steel during the making of steel, is described. A sample of steel to be tested is normally placed in an electrolytic cell wherein a known portion of the sample is dissolved electrolytically in dilute cold acid. The aluminum content of the resulting solution is determined spectrophotometrically. The apparatus is compact and readily installed near the steelmaking operation.

Granted: 1987-04-21
Abstract: Wolfgang Schmitz 5000 Koeln Abstract A permanent wave curler (41) has a roller sleeve (42) onto which a lock of hair can be rolled up and which, after the lock of hair has been rolled up, must be fixed with respect to the latter.  In order to prevent kinks from forming on the rolled-up lock of hair, stopping levers (43) are arranged at both ends of the roller sleeve, which levers lie approximately radially with respect to the sleeve axis and are rotatably mounted on the latter, it being possible to couple the stopping levers with the roller sleeve (42) at least in the direction in which the lock of hair is unwound.  The spindles (44, 45) of the stopping levers (43) are rotatable separately from each other and can be coupled with the roller sleeve (46) separately from each other (Fig. 6).

Abstract: ABSTRACT OF THE DISCLOSURE      A data processing system  includes a cathode ray tube (CRT) display subsystem and  a floppy disk subsystem.  The logic  of  both  systems  are verified  by  generating and transferring a  fixed format stream of  data bits from the CRT display subsystem to the  floppy disk  subsystem in modified frequency modulation (MFM)  mode and checking the information received by the  floppy disk subsystem against the  original  information  presented to  the  CRT display subsystem.     The bit  rate of the data  stream is varied depending on the number of address locations used in the data RAM of the CRT display subsystem to store each data bit.

Abstract: ABSTRACT          Apparatus is disclosed for compression molding a part from a charge having a curable resin therein.  Provision is made for defining a vacuum chamber surrounding the mold cavity when the upper and lower dies are brought to a partially closed position.          The vacuum chamber includes a vertically movable ring surrounding the upper die which is urged into sealing engagement with a surface surrounding the lower die.  The space between the ring and the upper die is sealed with a flexible diaphragm having an inner edge rigidly attached to the upper die and an outer periphery rigidly attached to the ring member thereby permitting relative vertical movement between the ring and die.  The mold cavity is rapidly evacuated and then the upper die is brought into a fully closed position while the resin cures.

Abstract: Abstract of the Disclosure Method and Apparatus for Extruding Reinforced Hose Extruded reinforced hoses are useful in fluid systems which operate at high pressures.  Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space.  Still other processes require extruding a hose on a mandrel and subsequently applying a fabric reinforcement member.  In these processes, the length of the hose is limited by the length of the mandrel. The present apparatus produces an extruded reinforced hose by braiding a metal reinforcement member on a mandrel and extruding a liner and cover at approximately the same location as the member leaves the mandrel.  The formed hose is pulled at a linear rate faster than the hose is being produced in order to change the braid angle of the braided member to a predetermined selected braid angle and holding for subsequent curing.  The metal braided reinforcement member provides the high strength characteristic while the extruding of the liner and the cover at approximately the same location near the mandrel eliminates the need for separate lengthy mandrels on which to extrude the hose, thus minimizing manufacturing floor space and reducing costs.

Abstract: ABSTRACT A relaxing snare for trapping animals comprising a noose having a constructible loop for ensnaring an animal therein by tightening of the loop about the animal's neck upon the animal tugging thereagainst, and a lost motion locking slide device for relaxing the tightness of the constricting loop in the absence of such tugging by a preselected limited amount of tension which is great enough to prevent strangulation of the animal yet small enough to prevent escape of the animal by withdrawal of its head through the loop when relaxed. This controlling feature is directly opposed to the strangulation resulting from use of the standard locking type snare and allows the selection and releasing of non-target animals. Various forms of a lost motion locking slide device are disclosed.

Abstract: THREAD ROLLING DIES FOR FORMING SELF TAPPING SCREWS AND THE LIKE              ABSTRACT OF THE DISCLOSURE          A method and apparatus for forming self tapping threaded fasteners having a cylindrical gripping portion and a tapered end portion with swaging lobes thereon is disclosed.  The apparatus includes a pair of flat dies having a flat G-surface formed with thread rolling grooves therein to form the gripping cylindrical portion of the fastener.  A rise angle surface having thread forming grooves therein with lobe forming recesses adja-cent to the finished end operate to form the tapered point with lobes thereon.  The G-surface is wider at the forward end of the die and progressively narrows until a dwell or finished portion is reached adjacent to the fin-ish end of the die.  Consequently, the threads along the tapered portion of the blank are not as fully formed as the threads along the cylindrical portion when the blank reaches the finishing end and excess material is availa-ble to fill the recesses and produce the lobes.

The undersides of the marginal zones of neighboring grate bars are undulate by exhibiting alternating teeth and tooth spaces which ensures rapid expulsion of solid particles which happen to penetrate between the lateral surfaces of neighboring grate bars when the movable grate bars reciprocate relative to the adjacent grate bars.  The flanks of teeth at the undersides of the marginal zones make with the upper sides of the respective grate bars acute angles of between 20 and 50 degrees, and the thickness of each marginal zone above the deepmost portion of a tooth space is a small fraction of the thickness of the marginal zone above the top land of a tooth.  The lateral surfaces of neighboring marginal zones define cutting edges which comminute the solid particles while the particles are in the process of descending toward the nearest tooth spaces so that they can leave the grate by gravity.

Abstract: ABSTRACT OF THE DISCLOSURE          The impact resistance of resin compositions consisting of a thermoplastic polymer, particularly a homopolymer or copolymer of vinyl chloride, can be improved by an impact additive of the graft copolymer type.  The graft copolymer impact additive consists of a backbone composed of a statistical copolymer of butadiene or isoprene, an alkyl acrylate of a C2 to C12 alkyl, and a polyfunctional cross-linking agent, onto which are grafted the chains of a polymer of an alkyl methacrylate of a C1 to C4 alkyl, particularly methyl methacrylate.  The backbone of the graft copolymer impact additive comprises 0.5-35% by weight butadiene or isoprene, and up to 10 mole % of the cross-linking agent, while the weight ratio of grafted chains to the backbone can range from 10 to 200%.  The resin compositions are particularly useful to improve impact strength at low temperatures.
