Abstract: QUICK OPENING REMOVABLE TRAY SECTIONS     FOR FLUID CONTACT VESSELS                            ABSTRACT           Novel quick opening removable tray sections or deck plates for the trays of fluid contact vessels having foldable closures or covers adapted to rest upon frame members which coact to form the perimeters of one or more polygonal, prefer-ably quadrangular, complementary openings in each tray.  Each of the covers has at least a pair of closure panels hingedly connected to each other at their adjacent inner margins.          Opposed outer lateral or side margins of the closure panels, which overlie complementary portions of lateral or side frame members in spaced relationship, extend in the same general direction as their adjacent inner margins.  At least one, preferably both, of these opposed outer lateral margins are slidably confined whereby the covers are removable upon ele-vating their closure panels at their hinged inner margins and simultaneously sliding said outer lateral margins of said panels toward each other and out of confinement so as to per-mit folding of said covers.  If desired, one of the opposed outer lateral margins of the closure panels may be hingedly connected to the adjacent edge portion of the tray instead of being slidably confined.  Frictional fasteners detachably secure the end margins of the closure panels adjacent their hinged connection to the underlying portions of the frame members at the opposed ends of each tray opening.  Usually, each of the quick opening tray sections is oblong and each of the hinged connections extends longitudinally between the closure panels whereby the latter are oblong and the lesser dimension or width of said tray section may be almost twice the maximum dimension of the manholes in the wall of the fluid contact vessel.  Also, it is desirable to provide a depending flange at least at one of the adjacent inner margins of the closure panels to facilitate mounting of the hinged connec-tion at the underside of said panels as well as to reinforce both of said inner panel margins.  Any one of the deck plates of the tray may be removably mounted in this manner.

Abstract: ADJUSTABLE SPINDLE LINER TUBE OR FILLER TUBE       ABSTRACT OF THE DISCLOSURE      An adjustable support for supporting bar or tube stock serving a turning machine spindle or feeder or stock support tube or the like.  It includes a tube having therethrough a through-opening of infinitely variable diameter concentric with the tube center line and coincident with the work centerline of the served unit.  The tube accommodates along its length a plurality of stock-supporting sections and at least one elongated longitudinally extending pusher-puller bars.  Each such section is defined by a pair of pushers and a pair of opening-defining stock-supporting rings.  The pushers and rings of each pair are mounted in spaced alternating disposition along the tube length.  Each ring has a pair of diametrically-opposed oppositely-facing tongues, each extending outwardly from one of its sides.  The rings of the pair are trunnion mounted relative to the tube with their axes disposed 90° apart, and are swingable unisonly between an opened stock-non-supporting position and myriad closed stock-supporting positions.  In opened position, they define a tube-through-opening of maximum diameter, and in closed positions, they define a tube-through-opening of less than maximum diameter as determined by the projection of the tongues inwardly toward the tube centerline.  The diameter is variable in indirect ratio with the degree of ring angularization - the greater the angularization, the smaller the through-opening.  The pushers are fixed to the pusher-puller bar or bars so as to be movable in opposite directions lengthwise of the tube.  As the pusher-puller bars and pushers are driven in one direction, each pusher is moved into a contacting relationship with a respective ring, the pusher pushing its ring in a swinging through-opening defining movement on its respective axis and a supporting embracement of each tongue with the stock periphery and as driven in counter direction a connector between each pusher and its respective ring pulls the rings away from non-stock supporting positions.

Abstract: DIFFUSION BONDING OF CRYSTALS                        ABSTRACT A method of bonding two crystals together is disclosed.  A bond enhancing material such as chromium (Cr) is vapor deposited on one crystal, and on this is vapor deposited a noble metal such as gold (Au).  On the other crystal a low melting point metal such as tin (Sn) or indium (In) is vapor deposited.  In the case of In this can either be directly on the crystal or on a layer of bond enhancing material; in the case of Sn this must be on a bond enhancing material.  On top of the low melting point metal a layer of the same noble metal is deposited to prevent oxidation thereof.  The noble metal layers are brought into contact with each other in vacuum or inert atmosphere and pressure applied thereto at a temperature of 100°C to 150°C in the case of In and 100°C to 200°C in the case of Sn.          The low melting point metal will diffuse into the noble metals and across the interface causing a bond to form by elimination of the boundary between the crystals.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to and discloses a novel process for extraction and separation of metals utilizing the advantages of liquid-liquid extraction with cation exchangers without requiring the equivalent addition of alkali.  The process comprises leaching the raw material with aqueous mineral acid, thereby forming an aqueous metal salt solution, extracting the metals including iron from said aqueous solution by contacting said solution with an organic liquid phase consisting of a cation exchanger component selected from the group consisting of organic carboxylic acids and alkyl phosphoric acids in solution in an organic solvent, the organic liquid phase containing a complex between at least one of the desired metals and the cation exchanger component, the complex having been formed by contacting said organic liquid phase with a desired metal-containing material which is different from the starting raw material to be leached, whereby the metals are exchanged between the organic phase and the aqueous phase and any iron present is transferred to the organic phase and forms a complex with the cation exchanger component and the desired metal of the complex passes from the organic phase to the aqueous solution, and then recovering desired metals from the aqueous solution.

Abstract: ABSTRACT OF THE DISCLOSURE           Copolyesters are provided which are derived from mixed dibasic acids and a branched-chain diol.  The copolyesters comprise the reaction product of essentially stoichiometric amounts of (a) a saturated aliphatic dicarboxylic acid having 4 to 12 carbon atoms, (b) a polymeric fatty acid containing 75% by weight or more C36 dibasic acid, and (c) a branched-chain aliphatic dihydric alcohol having 3 to 8 carbon atoms, a mixture of the branched-chain dihydric alcohols, or a mixture containing at least 50% by weight the branched-chain aliphatic dihydric alcohols and a straight-chain aliphatic dihydric alcohol having 2 to 8 carbon atoms, the equivalents ratio of (a) to (b) ranging from 0.80:0.20 to 0.97:0.03, the copolyesters having an average molecular weight of 2,000 to 8,000, (a) 210°F. kinematic viscosity from 2,000 to 8,000 centistokes and (a) density in the range of 1.015 to 1.060 g/cm3.  These copolyesters possess a unique balance of physical and chemical characteristics which permits their use in small amounts in blood separation tubes to provide an effective barrier between the light and heavy phases of the blood after centrifuging.  A small but effective amount of the copolyester which is sufficient to form the barrier between the phases is inserted directly into the separation tube either before or after the blood sample is collected. During the untracentrifuga-tion they locate between. the serum or plasma phase and the heavier cellular phase, and when the centrifugation is terminated form a continuous integral barrier within the assembly substantially to prevent the phases from re-combining or mixing especially when decanting or pipetting the light phase.

Casabona Relating to BUS FOR A DATA PROCESSING SYSTEM    WITH OVERLAPPED SEQUENCES                    Abstract of the Disclosure.         A digital data processing system including an interconnection for the various elements that constitute the system. Each element that connects to the interconnection is called a nexus. For one element to communicate with another element, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection. Control is the relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control, transmits the data onto the interconnection with an identification of one element. The one element then retrieves the data from the interconnection when it recognizes its own identification. If the other element is a memory element, it also contains storage file for storing commands and data if it already is operating in response to another element's command.

Abstract: ABSTRACT OF THE DISCLOSURE        When a pulse-width series modulator is connected to the cathode of an RF radio transmitter tube for the purpose of series modulation, filtration of the PWM switching signal is required to eliminate the switching signal from the output modulating signal.  Stray capacitive effects in this filtration generates undesirable distortion in the trailing edge of the signal appearing in the last stage of the PWM thereby producing non-linearity in the modulation of the RF output tube.  The present disclosure illustrates circuitry for complimentarily modifying the leading edge of the pulses so as to maintain a linear relationship in the time integral of voltage in the output signal.  This modification is accomplished through a plurality of capacitive units each having different time constants for charging and discharging.
