Abstract: Cushioned Shuttle Valve Abstract A shuttle valve includes a tubular body having two, coaxial, inlet ports at its ends, and a transverse outlet port at its side.  An internally threaded connec-tor ring is secured over each port by cap screws.     A cage having an external radial flange is tele-scopically disposed within each inlet port, with its flange clamped between the adjacent connector ring and an outwardly facing shoulder in the body.  O-rings seal the three connector rings and the two cages to the body.  Each cage has an inwardly protuberant O-ring secured at its outer end providing a valve seat. Inwardly of the seat each cage is axially grooved, providing flow passages.  The ribs left between the grooves provide guide bearings.  Adjacent the inner end of each cage are formed stop shoulders.  Inwardly of the stop shoulders is a skirt or lip forming a dashpot cylinder.     A shuttle in the form of a cylindrical plug tapered at each end is axially slidably disposed inside the body within the cages, being supported and guided by the bearing portions thereof, and adapted alternately to engage the seat of one or the other of the cages according to whether the pressure on one end of the shuttle or the other is higher.  A collar around the middle of the shuttle provides a dashpot piston.  When the collar enters a cage, the tapered end of the shuttle simultaneously engages the respective cage seat, trap-ping fluid between the shuttle and cage.  There is capillary clearance between the collar and lip to allow fluid to escape slowly.  This cushions shifting of the shuttle.  The collar finally comes to rest against the stops at the dinner end of the respective cage.  The ends of the plug are hollowed out to reduce weight and impact.

Abstract: Abstract of the Disclosure An improved process and apparatus for recovering hydrocar-bons from an air-hydrocarbon vapor mixture such as the mixture of air and vaporized light hydrocarbon compounds expelled as a result of loading gasoline or the like into storage tanks and tank trucks.  The air-hydrocarbon vapor mixture is caused to flow through a bed of solid adsorbent whereby the hydrocarbons are re-moved from the mixture and a residue gas stream comprised of sub-stantially hydrocarbon-free air is produced.  The substantially hydrocarbon-free air is vented to the atmosphere and a second bed of solid adsorbent having hydrocarbons adsorbed thereon is sub-jected to conditions which cause desorption of the hydrocarbons and thereby regeneration of the bed.  The flow pattern of the in-let air-hydrocarbon vapor mixture and the bed of solid adsorbent being regenerated are periodically changed so that when the bed through which the inlet air-hydrocarbon mixture is flowing be-comes loaded with adsorbed hydrocarbons, the inlet air-hydrocar-bon mixture is caused to flow through the bed which has just been regenerated.  The regeneration of the beds is accomplished by evacuating the beds with vacuum pumping whereby a major portion of the hydrocarbons are desorbed therefrom, subsequently intro-ducing a small quantity of heated hydrocarbon-free air into the beds whereby additional hydrocarbons are stripped therefrom and then subjecting the bed to further evacuation by ejector jet pumping while continuing to evacuate the bed by vacuum pumping whereby yet additional hydrocarbons are desorbed therefrom.  The air-hydrocarbon vapor mixture produced in the regeneration of the beds is contacted with a liquid absorbent whereby a major portion of the hydrocarbons are absorbed therefrom and recovered.  Appa-ratus for carrying out the process of the invention is also pro-vided.

Abstract: BREWING IMPROVEMENT                     Abstract of Disclosure Structure for maintaining and controlling qualitative and quantitative parameters of brewing, particularly related to coffee. A brew basket member, cap member, and cup member are provided. The brew basket cooperates with the cup member in such a manner as to provide upper extending flow conduit configuration means to allow the pouring of brew from the cup.  A vent is provided in the brew basket member.  The cap member has apertures to allow the flow of water therethrough and also has bent portions.                         Specifications This invention relates generally to brewing.  More particu-larly, this invention relates to the control of purity and quali-tative and quantitative parameters of brewing coffee and like beverages.     Prior to this invention, it has been a common practice in the art of brewing coffee to use a plurality of structures for main-taining controlled flow of liquid through comminuted particles in the process of forming a beverage solution.  A variety of pots and apertured devices have been used.  Portions of these structures have been disposable, while other portions require washing in order to maintain the quality and purity of the brew.    One of the problems of these past efforts has been the neces-sity to provide the labor to perform the washing process subsequent to the brewing process.  Another problem has been the time delay required for the washing between successive operations of brewing. Where attempts have been made to economize on the labor involved, not washing between every brewing operation, the quality and purity of the brewed product has suffered.

Abstract: Ultrasound Scan Conversion and Memory System Abstract Imaging information characterizable as a pixel grid or matrix of 256 image columns and 512 image rows is supplied by a scanning transducer means de-livering a series of ray lines of information where each ray corresponds to an image column.  The incoming pixels of the rays are converted into digitized data words, and stored for scan conversion by being routed, in simultaneous blocks of eight words, to a respective one of eight different page memories, in accordance with an image memory organization scheme assigning a different page routing number to each pixel of a block for the entire image matrix, to enable parallel memory access for both input and output operations.  The first page for the first pixel of each incoming ray is determined by logic which subtracts the ray or column number from eight, modulo 8.  subsequent pages are generated by in-crementing repetitively within the range 0, 1, 2... for each subsequent incoming pixel, after being set to said first page number.  Each page is associated with a corresponding element of an input buffer, to receive the corresponding pixel for each incoming column block.  All elements of the full buffer are dumped in parallel to the eight page memories simul-taneously.  This occurs repetitively for all blocks of each ray/column until each pixel of a frame is stored at an individually separate page address determined by simple arithmetical logic.  For output, the page memories are read out in rows, in simultaneous parallel row blocks of eight, one block element from each page, to an output buffer having an element connected to each page, with the page address for each pixel of a row block determined by a simple arithmetical operation.  The output buffer elements are fed serially to a video display sub-system in an order determined by the page routing numbers of the rows of the image memory organiza-tion scheme.  Simple circuitry determines the order of buffer element readout, with the first page buffer element number being simply the number of the image row being read out, (Modulo 8), and sub-sequent page/buffer element numbers of that row being generated incrementing repetitively within the range 0, 7, 6...1, after being set to said row first page number.  Such readout in successive rows of course effects conversion to a conventional video format for display.
