A combined brake cylinder/air reservoir device in which a relatively small, tubular-shaped piston in a positioning chamber is connected to a larger power piston having an application chamber on one side and a release chamber on the other side in which air is stored in place of separate reservoirs. A replaceable cylinder liner is provided to receive different-sized power pistons. During a brake app...

Flexible piles (5) are arranged close to the center of the tower (1) and evenly spaced apart on a circumference the area of which is about 10% of the area of the tower. The product of the total buoyancy of the tower by the arm level between the buoyancy center and the center of the articulation is at least equal to 1.25 times the product of the weight of the platform by the arm level between the c...

An apparatus and a method destined for the production of metal powder, wherein inert gas, especially argon is admixed to a metal melt rising in a riser, thereby forming a metal froth which is pressurized likewise by inert gas, especially argon of high pressure in a pulverization chamber, at the same time, forming metal droplets. These are displaced from the pulverization chamber by the gas blown i...

Corrosion is reduced in aqueous electrochemical cells having zinc anodes by utilizing single crystal zinc particles to which small amounts of one or more of indium, thallium, gallium, bismuth, cadmium, tin and lead have been added and amalgamated with mercury. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.

1. A process for the separation and simultaneous recovery of acid impurities, in particular CO2 , from gas mixtures containing a physically active solvent by pressure scrubbing, where the pressure above the charged solvent is reduced to a first intermediate pressure in order to de-gas co-absorbed inert substances and is then further reduced stepwise to separate the majority of the absorbed CO2 fro...

Each opposing wall (2) of the electronic unit, which incorporates a panel (10) has an aperture (8) in the unit outer casing. The panels are formed by an number of exchangeable plate units (13), each of which has two opposing parts, which jointly fill out the aperture. Each wall has a section (9) on the inside tracks (17) in which opposing edges of the plate units are accommodated. Several parallel...

The equipment comprises a shaft movable in a housing (2), on which are fitted vanes (12). These vanes are rotated by exhaust gases flowing past them. The shaft rotary movement is transmitted to the cardan shaft or similar of the vehicle.

Container closure has a female element (11a) attached to a flexible wall (10a) of a container and a male element (13a) attached to the opposite wall (12a), the container being closed by bringing the elements together in sealing engagement within the container. An axially operating sealing device (18a) is provided between the male and female elements and a bayonet type coupling (17a) between the el...

A closure comprises a female element for attaching to a flexible container wall, and a male element for attaching to an opposite wall, pref. also flexible. There is an axially operating seal between the elements, and a bayonet type locking device which presses the element and seal axially. The device is pref. formed integrally with the elements by interval injection moulding. The seal and/or eleme...

A rotatable holder fixes the pin of the drill crown in a grinding position in which the pin has its longitudinal axis aligned with the rotary axis of the holder. The pin rotates around its own longitudinal axis and a driven spindle is provided for the grinding tool. The grinding wheel (8) with its casing (7) is pressed against a projection (16) on the spindle (4) in a position in which its interio...

Ceramic cutting tool material has a matrix of silicon nitride or alumina in which is dispersed up to 35 wt.% of monocrystalline whiskers. The reinforcement includes at least 5% of each of two at least of the following: (a) fibres with dia. less than 1 micron and an aspect ratio of 15-150; (b) fibres with a dia. of 1-6 microns and an aspect ratio of 5-100; (c) discs with an equivalent dia. of 5-50 ...

The present invention relates to a device pertaining to a bulkhead door 26 or similar concealment element, which is located on through-running cargo decks on board ferries, for example. The bulkhead door is mounted pivotably between a closing and opening position and is mounted such that it can be pivoted essentially ca. 180 DEGREE, thereby enabling, inter alia, compact stacking of cargo alongside...

The invention relates to an unfoldable removable closing device for a furnace with open chambers with progressive heating, intended to interrupt the circulation of air between each of the heating partitions of a chamber and the corresponding partitions of the adjacent chamber, this circulation being effected normally through a passage made in the upper part of the transverse separation wall betwee...
