Disc brake with automatic adjustment incorporating a calliper (10) mounted so as to slide on a fixed support by way of at least one axial pillar, a brake actuator (34) acting directly upon a first friction component, and by reaction through the calliper, upon a second friction component, the brake actuator (34) incorporating a mechanical control (48-50-60) acting upon a hydraulic control piston (3...

An electric actuator having an electric motor operable to determine the output force generated on an output member by a spring; a drive shaft arranged to be driven by the electric motor and having first and second drive means, a non-rotational but axially movable intermediate member which is threadedly engaged with first driven means arranged to be driven by the first drive means; the spring being...

A wc disposable ostomy bag has a wall formed from an inner layer of polyethylene and an outer layer of polyvinyl alcohol. Two flexible layers of aluminum are located between the inner and outer layers to reduce odor transmission through the wall. The material of the walls may be formed by vapor depositing the aluminum layers on respective faces of the inner and outer layers and then laminating the...

Machine for winding a wire around a take-up roll comprises a flyer with two ends and motors to drive the ends seperately and directly, and pref. also has a measuring pulley, a scale plate and a die to guide the wire before it enters the flyer. There are pref. two pulleys, a capstan and a traverse for guiding wire within the flyer to the take-up roll. The arrangement eliminates the need for a dri...

This invention relates to an improved means to detachably secure a blade to a handle of medical examining devices such as laryngoscopes, which will secure the blade to the handle in at least two positions in an L-shaped configuration, one position being an operating position and one position being a ready position.

Articles conveyed one after another on a suppyling conveyor (1) are received by a deflecting part (7) and are deflected by 90 DEG from the travelling direction of said supplying conveyor (1) and are deposited by a chute (9) onto the surface of a receiving conveyor (2) travelling substantially at right angles to the supplying conveyor (1). By moving the deflecting part (7) parallel to the travelli...

A rail car tippler installation has an open-sided tippler with a rotatable structure (8) comprising a main longitudinal beam (16) mounted on end pivots (10, 18), said beam supporting a rail car platform (2) that substantially spans the distance between the end pivots. The main beam carries the weight of the rail car and platform during tipping and has pivot supports (30) for clamping beams (34) th...

System of covering for the making of closed, but easily reopenable, surfaces such as weather halls, shelters, furniture, wrapping etc., consisting of flexible, primarily two-dimensional materials such as foils, textiles, mats and similar, which are fixed to and interact with a load-bearing structure wherein the structural elements are furnished with recesses in or to which the flexible materials a...

The central hollow space in the tube (11) communicates in its rear part with one or more apertures (28) in the rod shaft part (13). These in turn work in conjunction with a surrounding casing to form a suction coupling for aspirating drilling dust from the bore hole.

Sensitive electrical material, e. g. lithium metal electrode material, protected by non-porous fluidimpermeable flexible material whose compositio can be altered, e. g. by solvent extraction of a salt or polymer therefrom, to render the protective material fluid-permeable. When the material is used as a cell electrode, the protective material composition is preferably altered on contact with liqui...

A device generates a signal corresponding to a variable magnitude associated with the reactive power of an arc furnace, in order to control a reactive power compensator. It comprises a reactive power or voltage demodulator and a set of filters connected to the output of the demodulator. The set of filters comprises active bandstop filters having a bandwidth of +/-F relative to frequencies of 2fO, ...

Hydrogen sulfide and/or carbon dioxide are removed from a sour gaseous stream in a contact zone by contacting the sour gaseous stream with H2S- and/or CO2- selective absorbent in an aqueous alkaline solution containing a polyvalent metal chelate at a pH of 7 to 10 wherein polyvalent metal chelate is in one embodiment of the invention in the reduced or lower valence state in a contact zone and is o...
