A device for holding the braking force of a motor vehicle has a braking force holding valve (22) in a brake operating fluid circuit. The device ascertains whether a load is imposed on an engine (4) of the motor vehicle based on detected signals (42, 51) indicating the amount of depression of an accelerator pedal (5) and the rotational speed of the engine. When there is a load acting on the engine,...

High strength and modulus articles of polyvinyl alcohol are obtained by thermoreversible gelation of a polyvinylalcohol solution, extraction of solvent using a mixture of a lower alcohol or ketone and water, followed by high stretching. Pref. a mixture of 5-80 vol.% of acetone and 95-20 vol.% of water is used as extractant. With this process extraction times of only 3-10 minutes are needed.

High strength and modulus articles, such as filaments, fibers, tapes, films, tubes, bars or profiles, are prepared by irradiating a solid, particular, lamellar, disentangled polyethylene with a Mw>4x105, transforming this polyethylene above the melt temperature into an article, cooling said article to below the melting point and stretching it in several steps at rising temperature but below the me...

FDN-1711 AQUEOUS PROCESS FOR PREPARING WATER-RESISTANT COATINGS OF HYDROPHOBIC COPOLYMERS MADE FROM HYDROPHILIC MONOMERS An aqueous process is described for preparing water-resistant coatings of hydrophobic copolymers of a predetermined composition. The hydrophobic copolymers are made from hydrophilic comonomers such as a vinyl lactam and a polymerizable carboxylic acid. The hydrophobic copolymers...

A female connector (1) for an electric wire (2) can receive contacts of an electric iron or a stand for the iron, and includes socket contacts (7) adjacent openings (10,11). Each socket contact (7) can receive a plug pin inserted in either corresponding opening (10,11). The openings (10, 11, 11') are distributed in two series respectively in two transverse faces (12, 13) of casing (6).

A filter particularly for use in the reservoir of a water cooling unit which comprises a body which is adapted to be received in the reservoir adjacent the top thereof, the filter having an inlet which is adapted to receive the neck of a water bottle or the like and having filter medium or media through which water passing from the inlet must pass before passing from the outlet to the reservoir an...

The invention relates to a process for purifying crude products containing esters of a non-reducing sugar like sucrose, and one or more fatty acids such as palmitic acid, stearic acid etc. by subjecting said crude esterification products to an extraction treatment with supercritical carbon dioxide. After carrying out this extraction treatment a residue comprising the fatty acid esters of non-reduc...

Digital multiprocessor methods and apparatus comprise a plurality of processors, including a first processor for normally processing an instruction stream including instructions from a first instruction source. At least one of the processors can transmit inserted-instructions to the first processor. Inserted-instructions are executed by the first processor in the same manner as, and without affect...

A digital data processing system includes a plurality of central processor units which share and access a common memory through a memory management element. The memory management element permits, inter alia. data in the common memory to be accessed in at least two modes. In the first mode, all central processing units requesting access to a given datum residing in memory are signalled of the datum...

32652CA A process for reactivating a spent, metal-contaminated zeolite-containing cracking catalyst composition comprises the substantially simultaneous contacting with a fluorine compound (preferably NH4F) and a metals passivating agent (preferably a compound of Sb or Ca). The thus reactivated cracking catalyst composition is employed in a catalytic cracking process.

An optical information system includes an optical source emitting light. An information recording member is exposed to the emitted light. A beam splitter disposed between the light emitting source and the information recording member separates light reflected by the information recording member and light traveling from the light emitting source to the information recording member. A device detects...

An electrically or petrol driven cylinder mower comprises a mower body 101 (Figure 2) and a grass box (Figure 3). An electric motor or petrol engine drives a cutter assembly 202, and also a turbo fan drawing air through an opening 207, both mounted in the body.. The grass box has a mouth 204 over the cutters and an opening 302 which mates with the opening 207 in the mower body, and through which t...

A power transmission system employs an endless belt having a toothed or ribbed friction surface and a smooth surface, the belt passing over a correspondingly toothed or ribbed drive pulley and over a smooth idler with a half twist between the two so that the smooth surface of the belt passes over the idler. A driven wheel suitably grooved or ribbed engages the surface of the belt where it passes o...

An electrically driven or petrol cylinder mower comprises a mower body 101 within which is mounted a removable cutter assembly 202. The cutting cylinder is driven from an electric motor or petrol engine within the mower body by a drive wheel 504, and is adjustable relative to the body by means of a toothed segment 601 engaging wheel coupled to an adjusting knob 403. The cutter assembly may be remo...
