Abstract: MEASURING AND TRANSMITTING APPARATUS       FOR USE IN A DRILL STRING Abstract of the Disclosure Measuring and transmitting apparatus is the subject matter of the preferred embodiment which comprises an elon-gate tubular member functioning as a drill collar and adapted to be placed in a drill string.  The apparatus utilizes a mud driven motor, while mud flows therethrough functioning as a drill collar and out the bottom.  The motor creates electric power which is used to operate selected transducers.  The transducers form measurements which are encoded.  The encoding portion of the equipment utilizes an oil reservoir, a mud driven pump, a valve which dumps the oil back to the reservoir if there is no signal and which other-wise delivers it to a two-position, four-way spool valve which drives a modulated signal generator.  The signal generator modulates the back pressure in the mud flow by restricting the mud flow, thereby forming a signal which is sensed in the mud flow path.

Abstract: ABSTRACT OF THE DISCLOSURE           Equipment for continuous ambulatory peritoneal dialysis in which a solution container is coupled via flexible tubing to a patient's tube that communicates with the patient's peritoneal cavity.   The  equipment  includes  a  flexible,  foldable plastic dialysis solution container having a transfer port.  A flexible tube having a luer connector at its distal end extends from the transfer port, for connecting to a luer connector carried by the patient's  tube.  The flexible tube carries a frangible member which normally blocks fluid flow but permits fluid flow after the frangible member is broken.  A particulate filter and a manually-operable clamp are in series with the flexible tube.          Peritoneal dialysis is accomplished by connecting the luer connector from a fresh dialysis solution bag to the patient's tube luer connector, breaking the frangible member, and opening the clamp on the flexible tubing.  After the dialysis solution is introduced into the patient's peritoneal cavity and remains there for a predetermined time, the solution is drained back into the flexible  bag,  the  luer  connectors  are  disconnected and the foregoing steps  are  repeated.   If desired,  once the dialysis solution has been introduced into the patient's peritoneal cavity, the luer connections may be disconnected and the patient's tube luer connector may be capped.

Abstract: (P-39/015) ABSTRACT OF THE DISCLOSURE          The method comprises contacting a sample containing an unknown quantity of a first immuno-reactive substance selected from haptens, antigens and mixtures thereof, to be detected and quantitated, with (a) a known quantity of a reagent containing a known concentration of an antibody specific for that first immuno-reactive substance, and (b) a solid phase having a known concentration of a second immuno-reactive substance selected from haptens, antigens and mixtures thereof reactible with the antibody to be passively adsorbed to the solid phase.  The contacting is effected for a time sufficient to cause the first and second immuno-reactive substances to combine competitively with the antibody.  The solid phase is then isolated, bearing with it the second immuno-reactive substance and the antibody bound thereto.  That antibody is then labeled by any suitable means and thereafter the concentration of the labeling bound to the antibody is determined as a measure of the concentration of the antibody bound to the solid phase and as a measure of the first immuno-reactive substance initially present in the sample.  The sample and the reagent containing the antibody are in the liquid phase and the sample and reagent may either be mixed together and reacted before contacting the solid phase or, alternately, the sample, reagent and solid phase may contact each other simultaneously for the first time.  An enzyme or a radioactive material or the like may be used as the labeling agent.  The method has improved sensitivity and adaptability and does not require  the use of dangerous or expensive reagents.

Abstract: ABSTRACT Device for reconstructing layer images of a three-dimensional object by means of an adjustable imaging matrix.         A device for the layer-wise imaging of the interior of a three-dimensional object which is irradiated from a large number of radiation source positions which are dis-tributed in one plane in order to obtain a coded image of the object which consists of separate perspective images. The coded image is illuminated and imaged by means of an imaging matrix whose imaging elements are distributed in the matrix plane in accordance with the flat distribution of the radia-tion source positions. Layer images of the object are formed on a photo-sensitive element by the superposition of the perspective images. For the formation of different layer images of the object, the imaging elements are positioned each time in different distributions of changed scale with respect to the distribution of the radiation source positions.

The liquid medium may contain agents furnishing HS'-ions or agents capable of dissolving silver halide or reducing silver halide.  If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action.  With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded.

Abstract: METHOD OF SPIRAL WINDING STRIP MATERIAL            Abstract of the Disclosure Strip material 5 coming from a letoff position 14 is wound on a supply reel 10 by rotating the reel 10 while at the same time providing axial movement of the reel 10 relative to the letoff.  The axial movement is stopped for a predetermined period of time when the strip 5 reaches an end portion of the reel 10 and before the relative axial movement is reversed to form another layer on the reel 10 to provide a supporting edge surface for other layers and reduce the induced curl in the strip material 5.  Each successive layer of strip 5 may be of a shorter length to provide a pyramid configuration to maintain the position of the windings.  This method may be controlled by a micro-processor programmed with a basic sequence which can be altered by the operator to set the number f base layers, the number of pyramid layers and the duration . of the interval during which there is no relative axial movement of the shell and the letoff at the end of each pass on the supply reel 10.
