Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides an analysis procedure in which reagents and a sample solution in an optically-thin layer chemically react to produce a reaction product that is a known measure of a constituent in the sample solution.  Use is made of fibrous sheets which are essentially non-absorbing and uniform in structure within and contiguously beyond the reaction site to generally eliminate the need of using confined test sites.  The layer is examined under electromagnetic radiation with a sensing means that responds in a linear manner to the concentration of a selected constituent-manifesting product of the reaction.  The invention enables such measurements to be made repeatedly with precision even when the spatial distributions of the material being analysed and of the reaction-producing reagents over the thin layer both are not uniform and differ from one another, provided that the distributions are the same for successive samples.

Abstract: ABSTRACT OF THE DISCLOSURE      For examining a body by means of X-rays or other penetrating radiation, data is determined representing the absorption suffered by each of a plurality of beams which are passed through the body.  The beams are effectively arranged in a plurality of sets of beams, in a single plane, at many different angles.   The arrangement is such that the amount of information provided by the teams is a function, which is in part non-uniform, of the beam position in the set.   A reconstruction of the distribution of absorption of the radiation within a part of the body is derived from the absorption data so determined.

Abstract: ABSTRACT OF THE DISCLOSURE:          The present invention relates to novel thiazole deriva-tives of the general formula I                                (I)   wherein R1 and R2 stand for hydrogen atoms or alkyl groups, and R3 stands for an oxo, hydroxyl or acyloxy group.  Furthermore, the in-vention relates to processes for preparing these compounds.  On investigating the biological properties of the compounds of the general formula I, it has been found that they have prostaglandin-like effects on certain organs.  From the aspect of therapeutic application their action is more selective than that of native prostaglandins.  They possess the valuable property of inhibiting the activity of enzymes inducing the decomposition of prostaglan-dins in the organism and thus they promote the rise of the endoge-nous level of prostaglandins.

Abstract: ABSTRACT   An impact mill has a rotor with beater bars sweeping on a beating circle, a mill housing, and an impact or grinding mechanism pivotably mounted in the mill housing adjacent the rotor.  A cover plate of the housing forms stop means to prevent the mechanism from pivoting too far towards the rotor and to thereby determine a gap between the mechanism and the beating circle, Two shafts extend through the cover plate and are connected at one of their ends to the mechanism,  Attachment members e.g. transverse beam uniting the parts of the shafts located outside the cover plate are provided on these parts of the shafts,  A hydraulic cylinder-piston unit is connected at one end to the mill housing and at the other end to the attachment members or the transverse beam.  This connection is provided with a lost motion corresponding to the amount the mechanism must freely pivot outwardly away from the rotor during use.  A wedge or step wedge type insert piece is arranged between the attachment members or the transverse beam and the cover plate.  This insert piece is displaceable in order to adjust the size of the gap.

Title: Balanced stem fall-safe valve system
Inventor: HERD DAVID P
IPC: F16K31/122
Filed: 1975-10-20
Granted: 1978-11-21
Abstract: ABSTRACT OF INVENTION   A balanced stem fail-safe valve controls flow of fluids through a submerged pipeline.  A closed subsea hydraulic pressure system operates or powers the valve.  In the fail-safe mode the operating or reservoir pressure equals ambient sea pressure.  A valve housing is arranged on the pipeline and a valve chamber is formed in the valve housing.  A valve element is movable in the valve chamber between open and closed positions to control the flow of fluids through the pipeline.  A first fluid pressure operable means is connected to the valve element to move the valve element to open position upon application of pump pressure to the first fluid pressure operable means.  Electrically operated valves are used to direct the flow of power fluid to and from the valve.  A spring is arranged in the valve housing to urge the valve element to its closed position in the event of power failure.  A second fluid pressure operable means detached from the valve element engages the valve element upon application of operating or reservoir pressure to the second fluid pressure operable means to balance any unwanted force which might occur when the ambient pressure is greater than the internal valve pressure and permit the spring to close the valve element.  The valve operator may be removable by means of a remotely operated manipulator for repair or replacement of the valve system or portions thereof.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to screen printing apparatus for applying dye or other coloring material under pressure to pile materials, and particularly to pile carpets and rugs.  The invention provides an upper assembly for receiving and containing dye under pressure and a lower assembly capable of receiving the dye under pressure from the upper assembly and applying the same under pressure to pile materials located thereunder.  The lower assembly comprises (1) a cylindrical rotatable flow control rod to stop or to resume the receiving of the dye from the upper assembly, and (2) a relatively narrow slot to control the application of the dye under pressure to the pile materials located thereunder.  Thus it is possible to uniformly apply dye to relatively thick pile material and to obtain uniform deep color penetration.  It is also possible with the inven-tion to precisely and promptly start or stop the flow of dye as desired during intermittent flow conditions.

Abstract: ABSTRACT            A disposable filter unit for use with a parts washer or the like.  The filter consists of a body in the general form of a bag, made from a softenable but substantially solvent-impermeable thermoplastic material having a neck portion attached to a mount-ing collar.  The mounting collar is a stiff but resilient element suitable for being positioned and retained within the drain opening of the parts washer, being constantly held in place by a cup or screen.  The filter body has large by-pass openings in the neck, smaller openings in the upper body portion and still smaller openings in the lowermost portion.  The filter acts by trapping sharp-edged or jagged particles such as slivers and filings, both on the interior surface of the bag and within the openings.  Entrapment of the filtered material effectively creates a finer mesh filter, and the graduated opening sizes provide a combination filtration and settling action.
