To permit lateral deflection of a transport vehicle or car (1) which receives electrical energy from an overhead system (56) and, additionally, is guided thereby by guide rails (6), a connecting element in form of a telescoping rod (4) or a tension spring (4a) connects the vehicle to the overhead system (56) to receive electrical energy and, additionally, guidance information. In accordance with t...

The invention relates to a safety ski binding, in particular a heel holder, comprising a sole holder which is pivotal about a transverse axle supported on a bearing block secured to a base plate. The sole holder is under the influence of an opening spring which urges it into its opened position. The sole holder is held in the downhill skiing position by a locking rocker arm pivotally supported on ...

The present invention is directed to a process for the production of optionally cellular, polyurethane and/or polyurethane-urea moldings having an impervious skin by reacting in a closed mold a reaction mixture containing (a) at least one organic polyisocyanate, (b) at least one compound which has a molecular weight of about 400 to 12,000 and at least two isocyanate-reactive groups, and (c) option...

New dopamine derivatives are disclosed, which are tertiary amines and which exhibit especially dopaminergic properties, and which have the formula wherein R1 signifies an alkyl group containing at least 4 carbon atoms, a cycloalkyl alkyl group, a cycloalkyl group or a phenylalkyl group and R2 signifies an alkyl group, a cycloalkyl alkyl group, a cycloalkyl group, or a phenylalkyl group...

The invention relates to stabilizer-containing reactive components for the production of polyurethane foams having little or no tendency towards core discoloration which are characterized by a stabilizing addition of monomeric and/or oligomeric derivatives of the diphenylamine series, including the phenothiazine series. The invention also relates to new stabilizers of the diphenylamine and/or phen...

PURPOSE:To elevate the detection and separation capacity with an improved contrast in the dark view illumination, by controlling the focus of a lens receiving the scattered light of an illumination light due to surface defects of an object to be inspected so that the focus position thereof falls on the objects being inspected. CONSTITUTION:Light emitted from a light source 15 is made to irradiate ...

Polyurethane foam is modified by a post-treatment process comprising the steps of contacting the polyurethane foam with a swelling agent for the polyurethane foam and interpenetrating the swollen foam with a chemical additive, then shrinking the interpenetrated foam by removing the swelling agent under conditions where the chemical additive remains trapped in the polymeric structure of the foam.

A method of producing elastomeric silicone foams from a two-part system is disclosed. The method mixes the ingredients then allows a froth to form and cure at ambient temperature to an elastomeric silicone foam. The method mixes a vinyl-containing polydiorganosiloxane (1), a hydroxylated polydiorganosiloxane (2), a platinum catalyst (3), an organohydrogensiloxane (4) and a profoamer (5). The profo...

Syntactic foam with improved processing characteristics is disclosed wherein a blend of coupling agents and alkylphenol alkoxylates are used to improve processibility and reduce cure time of the syntactic foam system.

Text and graphics are justified along one physical dimension to a predetermined line of justification. A plurality of physical parameters are employed in the justification, each of the parameters is assigned a compression and an expansion adjustment ratio. Such ratios define the maximum adjustment range of each of the parameters. A priority of adjustment is assigned to each of the parameters such ...

The block brake unit for rail vehicles has a service brake which includes a transmission lever which is pivoted by a brake piston to shift an actuating rod coupled with a brake block carrier. A parking brake includes a spring-loaded cylinder which is coupled by a pivotable parking brake lever through a transmission lever to the actuating rod. An impact wedge coupling comprising a roller and wedge ...

Cement matrix composites of improved flexural toughness are prepared with polyethylene fibrids of high orientation from plexifilamentary structures as reinforcement.

An effluent precipitation and neutralization chamber is useful for treating x-ray photographic chemicals prior to discharging them into a drain. Desilvered photographic fixer is mixed with spent developer within the chamber. The resulting iron precipitates settle to the bottom of the chamber or adhere to ribbon-like flow restrictors within the chamber. Relatively clear fluid of approximately neutr...

Fibre composite systems, in particular fibre composite laminates, can be prepared advantageously from a fibre composite impregnated with a curable epoxide resin matrix containing: (a) a liquid epoxide resin or a liquid mixture of epoxide resins, (b) an aliphatic or cycloaliphatic primary monoamine and/or disecondary diamine and (c) a tertiary amine which cures by catalysis or (d) a cycloaliphatic ...
