Abstract: The disclosure relates to medical devices and methods of manufacturing medical devices. An orthopedic screw includes an inner core member having a head having a first outer diameter, a tip having a second outer diameter, and a body extending between the head and the tip and having a third outer diameter that is less than the first outer diameter and the second outer diameter. An outer body member is disposed circumferentially around the body of the inner core member and defines an outer body member external thread. The tip of the inner core member can define an inner core member external thread that forms an interrupted thread with the outer body member external thread.

Abstract: According to an aspect of the disclosure, a glass manufacturing system includes a hot-end subsystem, including: a submerged combustion melter that melts feedstock to produce molten glass; a stiller that receives the molten glass from the submerged combustion melter and that includes a stilling tank to still the molten glass and that is configured to control outflow of the stilled molten glass to effectively decouple viscosity of the molten glass from the flow rate of the molten glass and thereby control finer molten glass levels; and a finer that is mechanically decoupled from the stiller, and that receives and fines the stilled molten glass to produce fined molten glass. Many other aspects of the system are also disclosed and claimed.

Abstract: A propane gas-utilizing system includes a housing having propane gas and a propane leakage prevention material having a catalyst, scavenger, and/or oxidizer of the propane gas arranged in the housing and including at least one of (a) an oxide material having at least one composition of formula (I): Ru1-xMxO2 (I), where 0<x?0.1 and M is Ag, K, Pt, Rh, or Ir, or (b) an oxide material having at least one composition of formula (II): Co3-xMxO4 (II), where 0<x?0.3, and M is Pd, Cu, or Sr, or (c) an oxide material having at least one composition of formula (III): MM?xOy (III), where x is a stoichiometric ratio of M? to M, 0?x?1.5, y is a stoichiometric ratio of O to M, 1?y?3, M is an alkali metal, and M? (if x>0) is Y, Ce, Nb, Ta, La, Nd, Mn, Ag, Au, or Cr.

Abstract: The present invention relates to a method for equalizing states of charge of a plurality of battery modules (20) of a battery (10). The method comprises identifying each of the battery modules (20) which is to be discharged by means of a load resistor (30) which is associated with the respective battery module for the purpose of equalizing the states of charge. The method comprises carrying out, for each battery module (20) or each identified battery module (20), a first evaluation, which is associated with the respective battery module, of its state of charge which occurs at a first time on a first day and/or of a first quantity of electrical energy and/or of a second quantity of electrical energy. An estimate for the first quantity of energy can be supplied by an energy conversion system to the battery (10) during the first day. An estimate for the second quantity of energy is supplied by the battery (10) to a load during the first day.

Abstract: A process for the preparation of 1,4-phenylenediamine from 1,4-dihydroxybenzene at a temperature within the range of from about 300.degree. C. to 450.degree. C. and a pressure of from atmospheric to 3000 psig in the presence of an aminating agent, an inert hydrocarbon and an acidic alumina catalyst. p-Aminophenol can be aminated to 1,4-phenylenediamine with the same process.

Abstract: Process for production and recovery of fuel gases and organic liquids from biomass by use of an upflow furnace, wherein said biomass is preheated at a temperature of from 100.degree. C. to 1500.degree. C. and thermally converted at a temperature of from 200.degree. C. to 1000.degree. C. in a reducing atmosphere.

Abstract: A process for enzymatically converting whole plant biomass containing hydrocarbon-containing laticifers to soluble sugars and recovering hydrocarbons in increased yields which comprises hydrolyzing whole plant cellulosic material in the presence of enzymes, particularly cellulase, hemicellulase, and pectinase, to produce a hydrocarbon product and recovering from the hydrolysis products a major proportion of the cellulase, hemicellulase and pectinase enzymes for reuse.

Abstract: A process for production and recovery of hydrocarbons from hydrocarbon-containing whole plants in a form suitable for use as chemical feedstocks or as hydrocarbon energy sources which process comprises: (a) pulverizing by grinding or chopping hydrocarbon-containing whole plants selected from the group consisting of Euphorbiaceae, Apocynaceae, Asclepiadaceae, Compositae, Cactaceae and Pinaceae families to a suitable particle size, (b) drying and preheating said particles in a reducing atmosphere under positive pressure (c) passing said particles through a thermal conversion zone containing a reducing atmosphere and with a residence time of 1 second to about 30 minutes at a temperature within the range of from about 200.degree. C. to about 1000.degree. C., (d) separately recovering the condensable vapors as liquids and the noncondensable gases in a condition suitable for use as chemical feedstocks or as hydrocarbon fuels.
