Title: Process for electrodialytically controlling the  alkali metal ions in a tin-plating process
Inventor: HORN RICHARD E
IPC: C25D21/18
Filed: 1977-08-19
Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE         A  tin-plating  bath  containing  alkali  metal hydroxide is circulated through the anode compartment of an electrodialytic cell. The cathode compartment contains an electrolyte and when a current is impressed across the electrodialytic cell, the alkali metal ions in the plating bath migrate  through  the  cation permselective membrane separating the compartments and into the cathode compart-ment.  The stannate ions remain in the tin-plating bath in the anode compartment.   The removal of the alkali metal ions controls the alkali metal hydroxide content of the plating bath.  This electrodialytic treatment of the bath eliminates the conventional chemical treatment to remove the excess alkali metal hydroxide.   The electrodialytic cell may be positioned in the tin-plating bath and where feasible utilize the same power source as the plating bath.   Alkali metal stannate may also be recovered from the rinse water by passing the rinse water through a center compartment of a three compartment electrodialytic cell bounded by a cation and an anion or neutral perm-selective membrane.     Excess alkali metal ions may be removed from either the plating bath or the rinse water of an acid bath by passing the bath or rinse water through the center compartment of a three compartment cell that is bounded on both sides by a cationic permselective membrane.  The alkali metal ions are transferred from the center compartment, thus removing the excess alkali metal ions from the bath and rinse water.

Abstract: ABSTRACT OF THE DISCLOSURE           An axial split-pin tumbler-type lock mechanism includes a rotatable operating part and a stationary part, which adjoin at an interfacial plane.  Tumblers each including a driver element and a follower element are mounted in bores in the parts.  The bores meet in alignment at the interfacial plane, and the tumblers are movable back and forth in the aligned bores.  When the joints between the tumbler elements coincide with the interfacial plane upon insertion of a key, the operating part may be rotated by means of the key, to accomplish a desired function.  The lock mechanism is provided with structure making it resistant to picking, including adjacent pairs of aligned bores in longitudinal communication with each other to permit sidewise engagement of an element of a tumbler in one pair with an element of a tumbler in the remaining pair, and mechanical interlock means on a side surface of an element of a tumbler disposed in each of the adjacent pairs of aligned bores, the interlock means on respective elements being adapted for engagement with each other to interengage the elements, whereby when one of the latter tumbler element bridges the interfacial plane, appli-cation of picking torque to the operating part tends to move the elements laterally relative to each other to cause such interengagement thereof and thereby constrain the elements to move together as a unit in the axial direction.

Abstract: ABSTRACT OF THE DISCLOSURE     Capacitance measuring device for measuring a physical quantity proportional or inversely proportional to the capacitance X of a first capacitor. A oscillating circuit includes a second capacitor having a reference capacitance XE or the first capacitor during successive reference and measuring phases under control switching network respectively. A counter counts a predetermined oscillation pulse  number NE during the reference phase and a oscillation pulse number NX during the measuring phase, The duration of two phases are equal or in a predetermined ratio R by means of a counter-down-counter which  counts and down-counts the same num-ber of clock pulses at least a predetermined frequency. The change of the counting to down-counting condition is controlled by the counter when its count is equal to NE. The stopping of the counter is controlled by the counter-down-counter when its count is equal to zero at the end of the measuring phase. A displaying and computing unit computes the physical quantity in dependance on the capacitance value X = (NE XE) / (R Nx) which is not affected by the drifts of device components and interference capacitances.

Title: Pulping of lignocellulose with aqueous methanol/  catalyst mixture
Inventor: CHANG PEI-CHING
IPC: D21C3/02
Filed: 1978-11-27
Granted: 1982-09-14
Abstract: ABSTRACT OF THE DISCLOSURE     Lignocellulosic plant material is chemically converted to separated fiber of superior pulp properties having almost native cellulose strength with low residual lignin, by cooking fragments of lignocellulose in an aqueous methanol solvent mixture containing a recoverable metal salt catalyst, or a combination of a metal salt and a minor quantity of strong acid such as HC1, in a pressure vessel at temperatures between 185°C and 205°C, and preferably between 190 C and 200°C, for durations from 15 minutes to over one hour.          A wood/liquor proportion between 1:4 and 1:20 or higher is maintained,with a preferred ratio 1:5 to 1:10, and the water/ methanol ratio is between 1:1 to 1:4, the preferred ratio being 3:7.  The metal salt catalyst is a chloride or nitrate of one of the metals calcium, magnesium or barium, and is useful in concentr-ations between 0.005 molar to 1.0 molar.  For cooking hardwood the preferred range is 0.05 to 0.1 molar, while for softwood the range preferred is 0.2 molar to 0.05 molar.  Addition of HCl when cooking hard-to-delignify wood such as Spruce, in amount 0.0005 normal to 0.008 normal enhances rate and extent of delignification without significant damage to cellulose.           High pulp yields of the order of 54% to 56% of wood weight for Spruce with TAPPI (0.5) viscosity of 20 cps at Kappa number 35 are obtained, within 45 minutes, while Aspen can be cooked to a pulp yield of 62% with TAPPI (0.5) viscosity 22 cps at Kappa number 25 in less than 30 minutes.     Lignin is recovered by precipitation through liquor cooling and volatilizing methanol therefrom, as an undegraded low molecular weight powder soluble in usual lignin solvents; the part of the hemicelluloses converted to dissolved monomers and oligosaccharides is recoverable from the residue, and  the catalyst may be obtained for re-use.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE            Title:     MECHANISM FOR CLOSING EGG CONTAINERS     ABSTRACT OF THE DISCLOSURE_ Rod-like tools mounted on gears so as to be swung together and apart by a reciprocating drive and running across a conveyor intermittently moving loaded egg containers, likewise oriented across the conveyor, are moved together to fold over the top corrugated strips of the upstanding sides of the egg container,as presented to the machine,by 90°, to bring these strips into abuttment.         Each corrugated strip is backed by a flat strip and one of the two has tabs which are folded over by 180° and adhesively bonded to the other flat strip.  The folding over of the tabs is performed by a set of fingers that move between segments of the first-mentioned folding tools to raise the tabs at an oblique angle, after which push rods bend them over completely.  During these operations  adhesive is applied to the surfaces to be bonded so that the tabs will hold the container together after the first-mentioned folding tool and the finger and push-rod assembly are moved back out of the way of the transport path of the container so that the containers on the conveyor can proceed to the next station.
