Abstract: A military vehicle includes an engine, an energy storage system, an accessory drive coupled to the engine and including an air compressor and a first motor, a second motor coupled to an axle, and a clutch positioned between the engine and the second motor. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. In an engine mode, (i) the clutch does not receive the air supply such that the engine is coupled to the second motor and (ii) the engine drives (a) the accessory drive and (b) the axle through the second motor. In the electric mode, (i) the first motor drives the air compressor to compress air to facilitate supplying the air supply to the clutch to disengage the clutch and decouple the engine from the second motor and (ii) the second motor drives the axle.

Abstract: The invention relates to a method for production of polymeric hydroxylalkyl terminated polysulphides, whereby monomeric hydroxylalkyl terminated polysulphides are reacted with formaldehyde in the presence of an acid catalyst in the form of a solid acid, in particular, an acidic ion exchanger, in which the reaction water and optional added solvent and catalyst are separated off. The products are characterized by a very high uniformity (low polydispersity) and can advantageously be functionalized with subsequent reactions.

Abstract: A process for preparing dihydroxyethylene disulfide by reacting mercaptoethanol with oxygen, in which mercaptoethanol is reacted with oxygen or an oxygenous gas in the presence of ammonia and/or amines using copper salts or manganese salts.

Abstract: A method for the production of prepolymers by reaction of polysulphides with polyepoxides is disclosed, whereby polyepoxides are reacted with polysulphides, having at least two mercapto groups, in the presence of quaternary ammonium compounds as catalyst. The method permits a rapid quantitative reaction and gives uniform products with regard to functionality and the proportion of functional groups per weight unit. The products thus produced have stable, may be stored, may be cured in a very reproducible manner, or may be processed to give products with a defined property profile.

Abstract: Synchronization of a bus master to a bus slave permits the desired hierarchical structuring of buses by virtue of a bus slave on a bus receiving the synchronization information for an associated bus master is disclosed. A phase locked loop is used to filter this clock information and to regenerate missing clock pulses. This clock which is now “sound,” is supplied to one or more parallel bus masters of other buses, which generate the corresponding clock information using the necessary messages on the respective bus. This principle is independent of the respective bus system, which means that a plurality of identical buses or else different bus systems can be operated hierarchically in synchronization with one another.

Abstract: Disclosed is a method for producing polymeric polysulfides containing terminal epoxy groups, according to which polysulfides containing terminal thiol groups are reacted with an excess of epichlorohydrin and alkaline lye, water is azeotropically distilled away with epichlorohydrin, the epichlorohydrin-containing epoxidized polysulfide solution is separated from the eliminated salt, the epichlorohydrin is distilled away, and the residue is optionally purified by means of thin film distillation. The reaction product is particularly suitable for the production of high-quality sealants, adhesives, and coatings. Said product has a high degree of purity and an extremely low chlorine content. The inventive method does not require any additional organic solvents and is very environmentally friendly.

Abstract: The invention relates to a method for producing polymer polysulfides comprising epoxy end groups, by reacting polysulfides comprising thiol end groups with epichlorohydrine in the presence of aqueous alkali lye. According to the invention, the polysulfide comprising thiol end groups is optionally dosed with aqueous soda lye into a recipient containing epichlorohydrine and optionally aqueous alkali lye, and the reaction mixture is finished. The inventive method is carried out in one step and has considerable advantages in terms of process technique. It especially enables savings to be made in terms of measuring and regulating techniques and enables energy to be saved. Furthermore, it is essentially risk-free and very environmentally friendly, and therefore enables pure products to be produced.
