Title: Reduction of detectable species migration  in elements for the analysis of liquids
Inventor: SMITH-LEWIS MARGARET J
IPC: G01N31/22
Filed: 1978-08-04
Granted: 1982-05-04
Abstract: Abstract of the Disclosure An element for the analysis of liquids contains a radiation-transmissive, detectable species migration-inhibiting layer interposed between a porous radiation-blocking layer and a radiation-transmissive reagent layer.  All three layers are permeable to a predetermined analyte.  The reagent layer contains a composition that provides a detectable species such as a dye in proportion to the concentration of the analyte that diffuses into the reagent layer from the overlying porous radiation-blocking layer.  The detectable species migration-inhibiting layer acts to reduce the migration of, for example, dye from the reagent layer into the porous radiation-blocking layer, where the optical density of the dye cannot easily be measured.  Optionally, the above-described three layers can be carried on a radiation-transmissive support, and other layers such as spreading layers, registration layers, and subbing layers can also be present in the element.

Abstract: Abstract of the Disclosure Pellets adapted to be orally administered to ruminants are disclosed.  The pellets have a core of a material beneficial to the ruminant such as a nutrient and/or medicament, and a coating which protects the core in the environment of the rumen, and allows utiliza-tion of the core in the abomasum and/or intestines.  The coating comprises a polymeric matrix which is resistant to the mildly acidic environment of the rumen at pH of about 5.5 and a hydrophobic substance dispersed throughout the continuous matrix.  The continuity of the polymeric matrix is destroyed in the more acidic environment of the abomasum.

A tubing injector head is supported on a mast and is moveable to selected elevations along the mast.  The mast includes a lower section maintained in upright orientation, and an upper section which is pivotally joined to the lower section.  The injector head may be lowered below the pivot point and the mast folded for transportation purposes.  A chain drive maneuvers the injector head in one horizontal direction, and a fluid pressure cylinder maneuvers the injector head in a second horizontal direction generally orthogonal to the first. The chain drive is fitted with a worm gear coupling to positively lock the injector head in position.  A height-adjustable level wind tubing guide directs the tubing onto or off of a reel.  The base of the apparatus is fitted with a track along which a blowout preventer may be moved for subsequent positioning over a well.

Abstract: SNOW RETAINING GATE FOR SNOW PLOW                 Abstract of the Disclosure In a snow plow having a horizontally elongated blade that extends lengthwise obliquely to the direction of plow travel, a snow retaining gate is mounted in front of the plow blade to swing flatwise about a horizontal axis near the top of the plow blade and substantially parallel to the direction of plow travel. When raised, the gate wall is substantially horizontal but has downwardly concave curva-ture from rear to front for close fit of its rear portion under the forwardly-upwardly curved upper portion of the plow blade. The rear edge of the gate wall has a curved upper portion so that when the gate wall is in lowered substantially upright position its rear edge, along the full height thereof, is contiguous to the front surface of the plow blade. When in lowered position the gate wall is oriented substantially parallel to the direction of plow travel and thus prevents formation of a secondary snow bank.

Abstract: IMAGE INTERPOLATION SYSTEM                 ABSTRACT OF THE DISCLOSURE         Analog image data pixels are sampled and held to produce a box car wave representative of the image data.          Wave height differences are bridged by linear interpolation, with frequency enhancement imposed at the bridge junctures.  The modified image wave is thresholded and sampled at a multiple of the original frequency to provide an image pixel stream comprised of both original image pixels having one or more interpolated image pixels therebetween.         One or more intermediate image lines are interpolated by comparing binary image data, portions of which may be interpolated, on a pixel by pixel or multiple pixel basis one line pair at a time.  The pixel comparison produces an address used to identify a specific image pixel pattern from multiple image pixel patterns stored in memory.  The image pixel pattern taken from memory is used to form the interpolated intermediate line or lines.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus provide for the elimination of any net DC component from the transmission of binary data sequentially in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., O's, are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., l's, are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.  The onset of a sequence of second bit states following a first bit state that might introduce a DC component into the transmitted signal with normal transmission is detected by counting first bit states and producing a first indicating signal when the count is of parity indicating such sequence, and in response to the first indicating signal, a current bit and an adjacent bit the transmission of signal transitions is modified from the onset of such sequence to eliminate any DC component.          Preferably, the possibly troublesome sequences are encoded by encoding pairs of second bit states by a single transition early in the first bit cell of the pair.

Abstract: ABSTRACT OF THE DISCLOSURE         A programmable sequence controller is provided with a display signal processor for preparing and correcting a sequence program in combination with a CRT (or cathode ray tube) display device.  The signal processor simply effects signal processing of branch points and composition points in case where a so-called "ladder diagram" constituting the sequence diagram with relay symbols is prepared and displayed.  Branch information is stored in an FIFO (or first in first out) register.  The branch information is sequentially received and stored, and the information thus stored is read out in the order of storage, thus preparing the ladder diagram.  There are provided a register for instructing the FI operation and a register for instructing the FO operation.  The sequence display controller is applicable to the cases where a new ladder diagram is to be prepared, the diagram once prepared is corrected and the operation is checked.

Abstract: HEAT EXCHANGER WATER COLLECTION SYSTEM               ABSTRACT OF THE DISCLOSURE    A water separator consisting of a baffle and scupper is inserted inside the outlet header of a regenerative heat exchanger for removing water from the air discharged therefrom.  The cooled air which contains water droplets leaving the core of the heat exchanger is passed through a baffle constructed to provide a gradual restriction in area in order to increase flow velocity.  Heavy droplets of water are separated by the sudden change in airflow direction through the baffle and header.  The flow in-cluding the heavier centrifuged water droplets then im-pinge on the inside surface of the header to which the accumulated particles of water adhere and are accelerated by the airflow and the contour of the header toward a scupper located downstream of the baffle opening.  The water is collected in the scupper cavity, collected in a drain well, and drained with the assistance of gravity and the resulting pressure differential across the drain port.  The scupper contains holes or louvered slots whereby some air used to carry the water along the header inner surface may pass therethrough to combine with the remaining airflow in a duct through which the dried air is removed from the system.
