Title: Steel prodn. in top and bottom blown converter - with bottom nozzles fed at least periodically with solids-laden oxygen-free gas
Inventor: BROTZMANN KARL DR ING
IPC: C21C5/32
Filed: 1979-12-11
Abstract: In steel prodn. in a converter having nozzles positioned below the bath surface and a water-cooled lance and/or nozzle positioned above the bath surface, oxygen is supplied from the lance and/or nozzle onto the bath surface and, at least periodically, only an oxygen-free gas, contg. particulate solids for slag forming or heat prodn., is blown into the bath through the subsurface nozzles. The process results in a well controlled low carbon content in the finished steel and reduced iron loss in the slag, e.g. a carbon content in the steel of 0.03% and an iron content in the slag of 12% can be obtd. Additionally, the steel has low hydrogen and nitrogen contents.

Patent DE-3007231-A1 (DE)
Title: Emergency control system for traffic signals - has directional receiver located in traffic light responsive to coded signals from microwave transmitter in emergency vehicle
Inventor: FAERBER NELSON A
IPC: G08G1/087
Filed: 1980-02-27
Abstract: The emergency control system uses a coded emergency signal transmitted from an emergency vehicle to generate a command emergency signal which activates a control unit. The existing state of the traffic signals is sampled and the information stored after which the control unit switches control of the traffic signals from the main controller to the control unit which determines from the stored information the existing state of the traffic signals. The information from the receiver as to the direction of approach of the emergency vehicle, the correct sequence for placing the traffic signals in the proper state, the discontinuation of the emergency signal initiates the return of control of the traffic signals to the main controller by the control unit on the first amber light function output from the main controller.

Abstract: The pressure force or acceleration transducer consists of a sensor element mounted upon a mechanically deformable substrate. It is an economically manufactured, sensitive device which does not suffer from the long-term stability limitations conventionally associated with integrated semiconductor sensor circuits with piezoresistive elements caused by humidity and corrosive gases or vapours. The sensor element (1) is mounted inside a housing (6) which is hermetically sealed by a membrane (8) in contact with the deformable substrate (3). The sensor element may be a strain gauge or an integrated semiconducting circuit with a piezoresistive element. The deformable substrate (3) may be a steel spring. Alternatively, the sensor element and substrate may be a flexible silicon strip. The sensor and substrate assembly is attached to the housing using a slotted metal ring (4) and threaded ring (5).

Title: Sealed housing for rotary filter - prevents smells escaping from treated liq.
Inventor: KARWATZKI AXEL
IPC: B01D35/143
Filed: 1980-04-11
Abstract: A horizontally rotating filter drum for removing solid impurities from liq. together with the associated tanks for the liq. before and after filtering and the containers for the removal solids are all enclosed in a transportable housing sealed to prevent emission of smells.

The trunking (10) is first fixed to a base plate (16) which has a central aperture (18). Around the aperture are predrilled holes (22) which align with ribbed (12) screw-threaded retainer (14) on the inside of the trunking (10). The base plate (16) has predrilled holes (24) on the outer perimeter, which stand proud of the trunking (10) when screwed into position, for fixing the base plate to the floor. The base plate (16) central aperture (18) can house a plug and socket arrangement (20) of various types as required for any electrical or communications installation. In alternative designs these plug and sockets (20) are screwed into the floor or trunking base as required.

Title: Sludge prior dewatering device - uses endless belt above top belt running at differential speed
Inventor: ALTMEYER HANS J
IPC: B30B9/24
Filed: 1980-06-30
Abstract: A device for the prior dewatering of sludge from a coal washery, ceramic, municipal or industrial wastes, which is to enter an endless belt filter press, is equipped with two water permeable endless belts which leave a slight gap between their adjacent strands. The sludge is fed to the gap by the return drum of the top belt which has been charged at the other end on its top strand. One of the belt speeds is adjustable to maintain a relative speed differential. This is a low-cost solution because the lower belt is simultaneously the top belt of the belt filter press. The differential applied causes a tearing action on the sludge particles and speeds up the pre-dewatering.

Title: Hydraulic or pneumatic pressure transmitter - has high pressure pistons with two seals, and intermediate spaces charged at permissible seal pressure
Inventor: HOETGER KARL
IPC: F15B3/00
Filed: 1980-07-23
Abstract: The pressure transmitter has a double-sided working piston, which is connected at each end to a high pressure piston. Each high pressure piston (4) has two sealing rings (5). A pipe (9) opens into the space (6) between the seals, and extends into the bore of the high pressure cylinders. The pipe charges the space with a pressure, which corresponds at max. to the permissible pressure of the sealing rings. The two pipes are each connected to different spaces of the working cylinder (2), resp. to pipes (18,19) leading to these spaces. Due to this, a working cylinder space, and the intermediate space between two sealing rings of an active cylinder (7), are charged at the same time.

Title: Tubular fabric straightener - has curved surface to deflect fabric path and eliminate distortion
Inventor: GOENNER KARL
IPC: D04B15/88
Filed: 1980-08-16
Abstract: The curved section, to support the deflected path of the tubular knit goods by its curve running across the line of fabric travel, is so profiled that the relative speed between its contact surface and the fabric remains approximately constant over the whole fabric width. The mechanism prevents any distortion or bowing in the tubular fabric as it is drawn out of the circular knitter, without requiring adjustment during running. Any adjustments which may be needed only occur after long time intervals.
