The method of forming a casing element of a braking assistance booster preforming the casing element to the required transverse dimensions and posiitoning the casing on a stationary annular frame. The casing is supported on the frame by its peripheral sleeve portion. The annular reinforcement is installed on the inner face of the base portion. A reinforcement is installed on the base with a unif...

A process and apparatus for the auto-thermal production of hydrogen rich synthesis gas wherein a mixture of steam and a hydrocarbon feed gas is reacted by passing through a catalyst counter-currently to the flow of the combustion reaction effluent of the process. Reaction tubes are mounted within a heat exchange chamber of the reactor and are adapted to contain catalyst to effect the reaction of t...

Process for elimination of wastes contg. petroleum comprises: (1) intensively mixing, in a proportion of at least 3:1 by wt., solid communal wastes of apparent density 300-500 kg/cu, m. contg. at least 20 wt.% of organic substances, with the oil-contg. wastes, e.g. from petroleum or the by-prods. of its processing, so that the content of the petroleum-contg. mixt. is a max. of 5 wt.%; (2) depositi...

An implantable prosthesis for splicing nerve ends comprises an elongate prosthetic element (1) of bioresorbable material provided with a plurality of channels (2) which extend between the ends of the prosthetic element (1) and are intended to serve as growth rooms for one or more nerve fibres or bundles thereof.

A cyanic liquid contg. copper (I) cyanic complex ion is treated by heating the liquid at temp. not lower than 200≰C in the presence of water soluble metal hydroxide. Pref. water soluble metal hydroxide is at least one selected from LiOH, NaOH, KOH, Ca(OH)2, Ba(OH)2 and strontium hydroxide. The decomposition of CN gp. is achieved at high rate in single batch process with low sludge generation eve...

A contact device for plugs is arranged on the component side of the printed circuitboard and includes soldered connections which penetrate through the printed circuitboard and are soldered to conductor paths of the printed circuitboard on the opposite side thereof. The countercontacts of a plug can be inserted from the soldering side of the printed circuitboard and penetrate through a recess throu...

An apparatus and method for fusing the ends of battery cell terminal posts and the ends of hollow bushings fixed in the plastic cover of a battery being assembled and within which the terminal posts are concentrically disposed. The apparatus includes a pair of induction heating coils which each concentrically support a mold cavity insert adapted to receive the ends of the terminal posts and bushin...

Carbon dioxide is separated from light hydrocarbons such as methane and ethane by absorbing CO2 gas with water at a pressure of at least 500 psia thus avoiding the CO2-C2H6 azeotrope problem. The CO2 is recovered from the absorbing water by pressure reduction and flashing and/or by heating and flashing. The process is particularly applicable to the recovery of high pressure pure carbon dioxide fro...

A 2-oxa-isocephem compound of the formula (1): wherein R<1>, R<2>, R<3> and R<4> are various substituents, pharmaceutically acceptable salts thereof, composition containing the same and processes for preparing the same are disclosed. The compound is useful as an antimicrobial agent.

The current generator (1) is adjusted so that it attempts to maintain an unaltered control signal w.r.t. its current, independently of the impedance variations in the control loop (2), but permitting voltage variations over the control loop dependent upon the alterations in impedance. At least some of the mobile units (3, 4) transmit a data signal to the control loop, resulting in voltage variatio...

Appts. comprises a liq. pumping unit having a pump chamber connected to a main chamber, with the inlet connection having a much lower flow resistance in the direction into the pumping chamber than in the reserve direction, and with the outlet connection having a lower flow resistance out of the pumping chamber than in the reverse direction. Cyclic depression or overpressure in the pump chamber rel...
