Title: Storage plant for converter exhaust gas - which can either be fed into gasometer or burnt as flare in exhaust gas chimney
Inventor: HEGEMANN KARL-RUDOLF ING GRAD
IPC: C21C5/40
Filed: 1980-11-19
Abstract: Gas obtd. during the oxygen blowing of a converter is driven by a fan up a pressure duct with three branches, each contg. a shutter valve actuated by a measuring and control appts. One branch leads directly to a chimney employed to burn the converter exhaust gas as a flare; the second branch consists of a by-pass also leading to the chimney; whereas the third branch leads to a gasometer. The gas pressure in the gasometer is used to open or close the shutter valve leading directly to the chimney; and a non-return valve is located in the branch leading to the gasometer. The measuring and control appts. is used for continuous determn. of O2 and CO in the gas, so only gas with a desired compsn. is fed to the gasometer; and the gas is only fed to the gasometer when the latter has adequate storage capacity.

Title: Propulsion unit for underwater vessels
Inventor: MEINKE JUERGEN
IPC: B63G8/16
Filed: 1981-07-17
Abstract: The invention relates to a propulsion unit for, in particular, unmanned underwater vessels which are composed of several modules of disc-like shape. The propulsion unit consists of a structure frame of disc-like shape composed of tubular sections. Several driving mechanisms preferably identical to one another and equipped with propellers are mounted in the structure frame on one side in such a way that the directions of their thrust vectors are spatially offset from one another. Three driving mechanisms offset by 120 DEG  from one another preferably lie in one plane, while a fourth driving mechanism is arranged axially inside the propulsion unit. Spatially translatory movements as well as rotary movements can be obtained by suitable, if need be remote-controlled, different speeds of individual or several driving mechanisms. When two propulsion units of the same type are used at the two ends of an underwater vessel, the trim position of the underwater vessel can also be influenced. The motors used for the driving mechanisms can be electric motors or even hydraulic motors.

Patent DE-3133076-A1 (DE)
Title: Method for the production of billets for a continuous rolling train
Inventor: NEUMANN KLAUS DIPL ING
IPC: B21B1/46
Filed: 1981-08-21
Abstract: In the method, billets for a continuous rolling train are produced by a process in which, after continuous casting or roughing, they are deformed into a helix or spiral. After passing through the furnace positioned ahead of the train, the helices or spirals are bent open continuously and fed as straight feedstock to the rolling train. This provides a multiple of the hitherto customary billet length and eliminates the time between billets, the formation of scrap due to introduction errors and due to underlengths in the case of cooling bed operation etc. The process is similar to endless rolling.

Patent DE-3144920-A1 (DE)
Inventor: BAUER ADOLF
IPC: B29B7/22
Filed: 1981-11-12
Abstract: A mixing head for two reactive components, e.g. the components of a settable synthetic resin mixture, comprises a mixing chamber in which a plunger is shiftable to block and unblock the nozzle orifices and drive the reaction mixture from the chamber through an outlet. At least one of the nozzles is carried on a readily shifting slider which cooperates with a similarly shiftable obturating member to define a small premixing chamber, as desired, and deflect the mixture through at least 90 DEG  within the mixing chamber. This system is especially effective for the mixing of reactive components which have hitherto been found to be difficult to mix with conventional mixing heads.

Title: Fastening element, in particular for mounting panels and the like
Inventor: REINWARTH KLAUS
IPC: E04F13/08
Filed: 1982-04-30
Abstract: A dowel (3) is inserted into a dowel hole (1) in a wall (2), ceiling or the like and is anchored in a known manner by means of a screw (5). The screw has a hard marking tip (16) which advantageously extends centrically with respect to the axis of dowel and screw. If the object to be mounted, for example a facade panel or the like, which is made of softer material than the marking tip (16), is then pressed against the marking tip and in particular simultaneously against a plurality of marking tips situated at a distance from one another, the latter leave behind punch-like impressions on the rear (19) of the panel (10). This permits dimensionally accurate transference of the hole pattern of all the dowel holes (1) to the panel (10), so that the latter, after its holes, in particular blind holes (20), have been drilled, can be pushed onto the outwardly protruding dowel ends without further work. These dowel ends can be designed in the manner of a gluing head (11) or a simple push-on pin (9), so that the panel (10) or the like can be secured by means of friction and/or gluing, bonding and the like. If blind holes are produced, a concealed mounting results. Collars (7 and 8) permit mounting at a distance (21) from the surface (22). <IMAGE>

Filed: 1982-09-04
Abstract: A running wheel of a roller has wheel flanges arranged at a distance from one another and intended to dip into the grooves of a conveyor belt, between which flanges a braking element which is seated on the ribs of a conveyor belt is arranged. This braking element is in the shape of a ring with a smaller diameter than that of the wheel flange and engages with play with its inner circumference a cylindrical running wheel component arranged between the wheel flanges. This running wheel component is mounted on an axle held in a wheel fork. A brake block is attached to the back of the wheel fork, against which block the circular braking element presses at the top when the underside of the running roller is placed on the ribs of a conveyor belt. In order to avoid noise and to reduce wear, elastically resilient centring elements are connected relative to the wheel axle between the braking element and the cylindrical running wheel component in order to provide central bearing of the braking element.
