Abstract: ABSTRACT OF THE DISCLOSURE     The present invention concerns a process for the preparation of 3,3-dimethyl-allyl alcohol. In said process a 3,3-dimethyl-allyl halide is reacted with an alkaline carboxylate and the 3,3-dimethyl-allyl carboxylate thus obtained is hydrolyzed by treatment with an alkaline hydroxide.          Both reactions are carried out in a two-phase system, in the presence of a phase-transfer catalyst.  The 3,3-dimethyl-allyl alcohol is obtained in high yields without by-products due to isomerization reactions.

Abstract: ABSTRACT OF THE DISCLOSURE         Highly purified isobutylene, up to 99.9% pure, is obtained by treating a reaction mixture such as that recovered from an isobutylene-containing hydrocarbon mixture also containing an aqueous solution of an aliphatic carboxylic acid having 1 to 6 carbon atoms that has been reacted in an acidic ion exchanger and from which the unreacted hydrocarbons have been removed. The operative ingredients of the treated mixture are tertiary butyl alcohol, secondary butyl alcohol and their esters of the carboxylic acid employed. When treated with an acidic ion exchanger the carboxylic acid is first formed which inhibits the secondary butyl alcohol and secondary butyl ester of the acid from decomposing and high purity isobutylene is recovered therefrom by conventional distillation.

Title: Readily resettable torque-limiting coupling  device

Granted: 1982-06-08
Abstract: READILY RESETTABLE TORQUE-LIMITING COUPLING DEVICE               Abstract of the Disclosure The invention concerns a torque limiting coupling wherein a driven clutch member is normally constrained to rotate with a driving clutch member by balls confined in ball pockets in those two members, opening to their opposing flat faces.  The clutch members are biased relatively towards one another so that the balls can roll out of the pockets when the driven member is excessively loaded.  Coaxially between those members and rotatable relative to them are a disc-like synchronizing cage and a disc-like transfer cage.  The synchronizing cage has a radial slot for each ball that maintains the ball in predetermined circumferentially spaced relation to the other balls.  The transfer cage-has a first hole for each ball that registers with ball pockets and through which the ball extends during normal drive.  It also has a groove extending from each first hole in a fractional-turn spiral and terminating at a second hole.  Upon overload, each ball is guided along its groove and into the second hole.  While rolling along the groove the ball forces the transfer cage flatwise against the adjacent clutch member to frictionally confine the transfer cage against rotation relative to that member.  When in the second hole each ball rolls on the flat clutch member faces, propelling the cages for rotation with one another but relative to both clutch members.  Resetting is accomplished without tools by reverse rotation of one clutch member.

Abstract: ABSTRACT OF THE DISCLOSURE         A structural joint for joining two elements, the first element having an elongate major tongue of malleable deformable material and in one embodiment an elongate minor tongue, the second element having a curled tab.  The major and minor tongues define an elongate recess adapted to receive the curled tab on joint formation.  The two elements are pressed together to press the curled tab of the second element into the recess between the minor and major tongues of the first element and to cause the minor tongue and the second element to mutually penetrate and deform each other.         The major tongue is then deformed about the curled tab to form at least a portion of an encircling curl which contacts the curled tab's external surface.  When the elements are so joined, the gap between the major and minor tongues is less than the width of the curled tab, thereby precluding removal of the curled tab from the encircling curl.  In another embodiment the curled tab is curled about a wire which acts as a filler or support,and the major tongue is deformed about the curled tab as before.  The invention also comprises a ladder having rungs secured to side rails by structural joints in accordance with this invention.

Abstract: Abstract Radiant energy in conjunction with an n-type amorphous silicon semiconducting anode to at least partially power an electrolytic cell is used in the generation of hydrogen, utilizing a bromide, prefer-ably hydrogen bromide, as the essential electrolyte component in the electrolytic cell to solve overvoltage and corrosion problems associated with the use of con-ventional electrolytes in similar environments.  The use of the bromide electrolyte results in the broaden-ing of the selection of semiconductor electrodes which can be used in the process and apparatus of the present invention enabling the n-type amorphous silicon semi-conducting anode to be used with superior anticorrosive and radiant energy gathering results over conventional systems,  To insure against corrosion, the n-type amorphous silicon semiconductor should preferably be used with a thin layer of platinum overcoating.  The hydrogen generated from such system can be used to power a fuel cell.

Abstract: ABSTRACT OF THE DISCLOSURE          A secondary sealing element for an axial seal ring, which resists stresses due to temperature, pressure, vibration, corrosion, swelling and shrinking.  The sealing element is pro-duced from non-rubber-type elastic and non-brittle material and its shape in cross-section is a ring, with a pair of arms to give it an elastic action.  The double-arm ring forms three radial-type sealing surfaces and is completely locked into a chamber between the axial seal ring and the shaft.  A material with low static friction and higher thermal conductivity as rubber material is used.  The dissipation of heat, produced by the axial sliding ring will be increased through the double contact area with the shaft of the arms in comparison to an O-ring and through a wear-resistant and non-corrosive layer on the shaft having at least the thermal conductivity of the basic material.

The light metal sleeve can be welded or otherwise appropriately joined to light metal after impact extrusion. The production of a light metal shock absorber is a special case of plastic deformation of light metal and the principles which lead to metallic bonding between light metal and steel or another metal are also valid here.

Abstract: DISTRIBUTED ARRAY OF JOSEPHSON DEVICES   WITH COHERENCE                      ABSTRACT            Josephson devices are distributed in series in a transmission line structure in which electromagnetic waves are used to synchronize the dynamics of the Josephson devices in order to achieve coherence between the devices.  Electromagnetic waves, such as oscilla-tory traveling waves, standing waves, and solitary waves along the transmission line couple the Josephson devices in a manner such that coherence is achieved for the entire array.  The Josephson devices can be tunnel junctions, point contacts, micro bridges, and weak links, and more generally include any such superconductive device which obeys the Josephson equations of voltage and current.  The transmission line is any line which controllably supports electro-magnetic waves, and can include strip lines located over a ground plane, coaxial lines, etc.  A DC bias is supplied to the transmission line, and the ends are terminated in accordance with the type of wave to be propagated along the line.  Each Josephson device couples to the electromagnetic wave along the trans-mission line where many Josephson devices can be in series.  Typically, the Josephson devices are spaced closer than the wavelength of the electromagnetic wave although this is not a necessity.  The coherent array can be used for wave generation and detection, amplifi-cation, and as a voltage standard.
