Title: Refining cast iron - by blowing oxygen into a converter full of molten iron both above and below the melt level
Inventor: BROTZMANN KARL DR
IPC: C21C5/32
Filed: 1978-09-07
Abstract: Method of improving the heat balance and thus increasing the amt. of scrap that can be used in refining cast iron in a converter having oxygen tungenes below the bath surface with protective sheaths, and oxygen blowing devices above the bath level, is claimed in which during a large part of the refining period, 20-80% of the O2 is fed into the bath by jets directed toward the bath surface from above the bath surface, and the rest is blown in below the surface. The amount of O2 blown onto the surface from above is varied during the course of the refining. The properties of the steel produced are unaltered, despite the improved heat balance and the increased use of scrap. The axis of the free jets w.r.t. the surface of the bath make an angle with the axis of rotation of the converter of >35(>45) degrees.

Title: Plastic lined concrete pipe - with plastic filled grooves in end faces
IPC: F16L58/10
Filed: 1979-05-07
Abstract: A concrete pipe with an internal PVC lining which extends to both end faces has at one end and annular groove adjacent an embedded seal ring. The opposite end face has a wider annular groove which covers the width of the smaller groove and of the seal ring and acts as an abutment for the latter. The pref. material to fill both grooves is a plastic material which can be cast or be applied by spatula, is corrosion resistant and forms a good bond with the PVC. This protects the face ends of the pipes against corrosive attack by media flowing in the pipeline, even when the pipes are somewhat offset.

Patent DE-2922567-A1 (DE)
Inventor: HERB ARMIN
IPC: F16B13/08
Filed: 1979-06-01
Abstract: A fastening unit for use in a prepared borehole includes an anchoring member and a spreader wedge. The anchoring member is formed from a single piece of metal plate and consists of an axially elongated shank part and a flange at one end of the shank part. The flange extends perpendicularly of the shank part and is bent relative to the shank part so that an arched surface is located between the two parts of the anchoring member. The flange defines an opening through which the wedge extends. The surfaces within the opening of the flange and certain axially extending surfaces of the shank part guide the wedge as it slides axially relative to the anchoring member when the fastening unit is being anchored in a borehole. The wedge guiding surfaces on the anchoring member extend into the axially extending range of the wedge guiding surfaces of the flange.

Title: Pilger tube mill - with two feed carriages gearboxes and mandrel thrust blocks for higher throughput
Inventor: GERRETZ JOSEF
IPC: B21B21/04
Filed: 1979-06-01
Abstract: A Pilger or rotary forge mill for tubes has two gear boxes, driven by the main motor and driving separate feed carriages for the billet. Both feed carriages have a catch which acts against the rear of a billet to be fed forward. Both gear boxes are fitted with a rapid approach gear stage. The distance between the two mandrel thrust blocks in the gear boxes is made twice the length of a billet. This reduces the time of the break in the feed to a few seconds. During the transfer from one feed carriage to the other, at least one of the mandrel thrust blocks is closed so that the rolling mill stand need not be stopped. The throughput is therefore considerably raised (time loss of 4-8 instead of 26-60 seconds per billet).

Title: Treatment of sulphite waste liquors from pulp making - by heating with phosphoric acid, removing sulphur di:oxide and recovering phosphoric acid, giving prod. useful as fuel, ion exchanger etc.
Inventor: HAYEK ERICH DR
IPC: A23K1/14
Filed: 1979-07-17
Abstract: Treatment of sulphite pulp waste liquors is carried out by (a) adding H3PO4 or a substance which forms H3PO4 by hydrolysis, (b) boiling the mixt. to drive off SO2, and (c) recovering H3PO4. The H3PO4 converts sulphites, e.g. Ca(HSO3)2, to SO2 which is removed together with other volatile materials (furfural, cymene, MeCOOH and HCOOH) during step (b). The product remaining after H3PO4 recovery can be used as a fuel, an ion exchanger or water filter, and additive for plastics, rubber or asphalt, or as a soil improver or as a soil improver or animal feed additive.

Inventor: TOMKEWITSCH ROMUALD VON DIPL I
IPC: G08G1/09
Filed: 1979-11-13
Abstract: In a method for traffic determination, a routing and information system for individual motor vehicle traffic is used, in which by way of stationary routing station poles, route information and local information are transmitted to the passing vehicles. For the determination of the traffic situation, the traveling times between two routing station poles are measured in individual vehicles with timing units. These traveling times are transmitted, together with the local information of the first routing station pole passed by a vehicle, to the second routing station pole and are considered in determining new route recommendations.

Title: Picture shape correction for colour TV receiver - employing component tuned to twice scanning frequency in HV circuit of CRT
Inventor: POLLAK ALFRED
IPC: H04N3/237
Filed: 1980-01-17
Abstract: The proposed component is added to the transductor circuit (8) already provided to modulate the line scan voltage in order to correct for waisting of the image on the horizontal centre line. When using small transductor cores it has been found that compensation is not entirely adequate. The correction required for satisfactory picture shape can be resolved into a double frequency modulation added to the modulation introduced by the transductor. To achieve this a circuit (14,15) tuned to double frequency is added in parallel to the capacitor (11) between the deflector coils (9) and earth. The distortion produced by the transductor may be utilised as the correcting component by choice of inductance and capacitance in the tuned circuit.

Title: Gas pressure regulator with built-in safety valve - has safety diaphragm with vent valve that closes when main diaphragm fails
Inventor: BERTKE HEINRICH
IPC: G05D16/06
Filed: 1980-01-18
Abstract: A gas regulating valve includes a safety diaphragm with a valve stage that closes in the event of a main control diaphragm failure. Gas flows from inlet (14) to outlet (16) over a poppet valve (38) that is controlled by outlet pressure applied (42) to the underside of a main diaphragm (26), which reacts against the pressure applied by a coil spring (46). The main diaphragm is backed up by a safety diaphragm (48) that contains a safety valve (52). In normal operation the space between the main and safety diaphragm (56) is vented to atmosphere (54,58,44). In the main diaphragm fails, a small diaphragm (60) reacts to close off the vent path.

Title: Surface tension measurement of molten enamel, metal etc. - separating liq. beam at nodes of standing ultrasonic wave by increasing velocity amplitude
Inventor: HEIDE WOLFGANG MARTIN DIPL PHY
IPC: G01N13/02
Filed: 1980-03-26
Abstract: An arrangement for measurement of surface tension by feeding a sample of liquid into the region of a pressure node of a standing ultrasonic wave enables the advantages of dynamic measurement methods to be achieved with economical continuous measurement. The device may be used in a portable mode for rapid measurement, esp. with liquids whose qualities are variable. The liq. is fed in in the form of a liq. beam whose velocity amplitude is continuously increased in the modes until the beam separates. The separation velocity amplitude is the measure of the surface tension. It is increased by raising the ultrasonic generator (7) power or transmitter (3) amplitude for constant gar density or pressure. These values can be used as the measure of surface tension.
