Title: Inclusions free steel ingot - is obtained by raising casting temp. and using exothermic agent
Inventor: MATSUYAMA SHIGERU
IPC: B22D7/00
Filed: 1976-10-29
Abstract: The formation of inclusions in an ingot of killed or semi-killed steel is prevented by raising the temp. of the liquid steel, prior to casting, to 20 degrees C above the temp. at which the steel solidifies. The melt in the ingot mould is covered either during or immediately after casting, depending on whether the mould is filled from the bottom or top, with an exothermic agent. This agent is highly combustible in order to raise the total heat content per ton of molten steel to >1800 kcal. The time from the exothermic reaction to the max. temp. is not >4 min.

Title: Pen recorder drive mechanism - has stylus support which actuates paper feed when measured parameter exceeds nominal
Inventor: MROZEK CHRISTIAN DR RER NAT
IPC: G01D13/26
Filed: 1977-03-23
Abstract: A pen recorder is arranged to operate when the measured parameter departs from a preset nominal value. The recorder has a conventional ink reservoir and stylus to record variations in a parameter on a paper roll. The stylus is mounted on a pivoted lever, the rear section of which carries a counterbalancing weight. Attached to the stylus arm is a pointer which provides a visual read-out on a scale. At a predetermined position of the pointer is a support bridge which holds the stylus away from the paper. When the pointer is in the position occupied by the bridge, the paper drive is disconnected, so that recording only takes place when the parameter departs from its nominal value. The position of the support bridge can be set by means of a threaded control shaft.

Title: Overload protection circuit for liq. flow meter - has potentiometer across measuring cell to reduce voltage fluctuations caused by tube being empty or affected by foam
Inventor: BUSCHMANN HEINZ
IPC: G01P5/08
Filed: 1977-05-12
Abstract: The liquid flow meter has a transfer tube (13) through which a liquid is passed. Mounted in diametrically opposite positions on the wall of the tube are two electrodes (11, 12). These electrodes receive voltages dependent on the flow of liquid through the tube and pass them to the inputs of a sensitive two-channel amplifier (16). The conductivity sensed by the electrodes is subject to substantial fluctuations caused either by the tube being empty or by the passage of foam within the liquid. To reduce the effect of these fluctuations, a potentiometer (17) is connected across the electrodes. Its resistance value is of the order of the inverse of the expected liquid conductivity at the electrodes. A further fixed resistor (18) may be connected across the electrodes.

Inventor: BLINDOW FRIEDRICH-KARL DIPL IN
IPC: E21D9/10
Filed: 1977-05-27
Abstract: Underground cavities are produced in mining by means of shield tunnelling. Before the excavation, an annular gap of accurate profile is produced by means of highly accelerated hot gases at the end face of the shield at the projecting cavity margin, and then the excavation is carried out with mechanical or hot-gas-boring means. With this technique, the shield tunnelling system can be used in both solid rock and loose rock.

This chamber is closed by a flat cover(9) carrying a central discharge pipe(16). A perforated plate(15) around the inside end of this supports a coaxial conical baffle(19) pointing upstream; a cone-base dia. pipe downstream, forming an annular passage(14) to a chamber(10) inside the cover. Flow from this to a second chamber(18) inside the baffle is along several parallel paths(11, 12), which can be formed in a variety of ways, and through the perforated plate.

Title: Di:alkyl phthalate and adipate prodn. - by completing esterification of partially reacted mixt. in a flooded column; useful as plasticisers
Inventor: HORNBERGER PAUL DIPL CHEM DR
IPC: C07C67/08
Filed: 1977-07-21
Abstract: Complete esterification of dicarboxylic acids comprises introducing a mixt. of diester (I), monoester (II), alcohol (III) and esterification catalyst into a column at b.pt. of (III) or a temp. up to 40 degrees C. higher. The liq. mixt. passes up the flooded column in the same direction as water and alcohol vapour. The rise speed of the vapour bubbles is reduced, and water and (III) are removed as overhead, while crude (I) is taken off as a side-stream below the column head. The starting mixt. comprises 50-70 wt. % (ROOC)2A (A=1,2-phenylene or (CH2)4; R=4-11C alkyl); 3-15% HOOC.R.COOR; 27-35% ROH, and 0.05-0.1 wt. % catalyst. No azeotropic agent is needed to remove the water and a uniform temp. profile and constant boiling conditions are maintained in the column, so fractionation is avoided. Back-saponification of the prodn. does not occur.

Title: Plastic or fibrous material crusher - has wear resistant liner rings with sharp cutting edges on recesses producing rasping effect
Inventor: HORNBERGER OTMAR ING GRAD
IPC: B02C13/18
Filed: 1977-08-12
Abstract: The stator of the disintegrator is fitted with a wear resistant liner assembly on the inner surface of which recesses with sharp edges are arranged in such a way to produce rasping action of the material without producing heat which would make the material plastic. The wear resistant liners consist of rings(11, 12, 13). Each ring is fitted with recesses(22) distributed along the circumference. The recesses consist of inclined surfaces(20) with conicity narrowing towards the top of the stator. Each inclined surface(20) starts from a small horizontal platform which in itself has a shape with extended ends(23) joining a continuous vertical cutting edge(33) and (35). The recesses stacked vertically delay the vertical travel of the material downwards resulting in better disintegration.

Filed: 1977-09-29
Abstract: A process for filling a bulk material into a box (21, 43) containing a bag (22, 44), the quantity of bulk material to be filled is first filled into a rigid container open at the top by means of a filling device (2), this container being rotated in order to compact the bulk material. An empty box (21) together with a bag (22) is subsequently slipped over the filled container (20), and the container together with the box is tipped over twice in succession through 90 DEG by means of two tipping devices (15, 25). The container (42), the bottom of which is now at the top, is thereupon drawn out of the box (43) by means of a lifter (30), the bulk material being transferred out of the container (42) into the box (43) or, more precisely, into the bag (44) located in the latter. Air is supplied to the container interior through air-inlet ports in the container bottom. Furthermore, the container (42) is vibrated during the transfer operation. The full box (43) is thereafter rolled away. The container (54), now empty again, is transported back to the filling device (2) by means of conveying members (52, 55, 71) and is rotated into its original position again in two tipping operations by two tipping devices (45, 65). <IMAGE>
