Patent DE-1951324-A1 (DE)
Title: Electrolytic plating bath automatic - analysis and replenishment
Inventor: BUSSMANN EGON DIPL-PHYS DR RER
IPC: G05B19/06
Filed: 1969-10-10
Abstract: Automatic regulation of an electrolytic plating bath solution is by means of regular automatically initiated colorimetric titrations in which measured amounts of reagents are titrated with the electrolyte. As the results of the titration, which is automatically recorded by means of the action of a synchronously rotated cam shaft, the number of revolutions it performs being linked to the titration, a requisite amount of replenishing solution is added to the bath, two solutions being available in case of over running.

Patent DE-2048953-A1 (DE)
Title: Injection mould workpiece removal - using racks and operating cogs operated by mould movement
IPC: B29C45/42

Patent DE-2138020-A1 (DE)
Title: Multiple continuous cast rod conveying system - - with flying shears and waiting bed
Inventor: TROST ENGELBERT
IPC: B22D11/126
Filed: 1971-07-29
Abstract: The sections produced in parallel on a multiple continuous casting plant are cut up into lengths by flying shears and guided together and are deposited on a waiting bed. From this they are transferred in batches to a transverse transfer device which pushes them into a cooling bed, from which they are transferred to a buffer store. The sections move on roller conveyors, which converge so that adjacent rods are apart by 1.5 times their width. The system is capable of large throughput even of short length rods and requires little space. It is used in continuous casting plants with multiple casting moulds.

Patent DE-2156636-A1 (DE)
Title: Non-metallic impurity removal from continuous casting steel - - by tundish slag reaction
IPC: B22D1/00
Filed: 1971-11-15
Abstract: The impurities are removed from Al-killed soft steel for continuous casting by employing an intermediate wall partitioned vessel. The two parts of the vessel are interconnected by a channel near the bottom ending in an upwards bend for the melt to spurt upwards against a slag cover maintained on top of the melt in such away that it makes the slag layer bulge upwards after which the melt distributes itself and eventually runs out through the bottom of the vessel into the casting mould. The melt level in the first part of the vessel is maintained higher than in the second to obtain the required head for the melt jet to form. The method is intended mainly to remove Al2O3 from the soft steel which is used for cold rolled deep drawing steel strip.

Title: Secondary cooling of round ingots - to effect uniform cooling over the entire surface area and to prevent warping or disto
Inventor: BASCHKOW WLADIMIR A
IPC: B22D11/124
Filed: 1972-02-18
Abstract: Secondary cooling of round metal strands or ingots in the continuous casting of metals is effected over the entire side surface of the strand by an appts. incorporating cooled beams to hold the ingot casting and with nozzles to spray the casting(s) with coolant. The beams and the nozzles are combined into >=2 pairs of sections, each with the beams and nozzles distributed uniformly about the circumference and mounted on a thrust bearing and connected to its movable ring. At the same time the section can rotate about the vertical axis together with the other sections in opposite senses and is offsettable at an angle corresponding to the distance between the beams. This effects uniform coolant flow over the whole area of the moving casting to effect uniform cooling and facilitate quicker casting.

Title: Bed-linen cross-folding unit - with centre line on longitudinally-folded sheet determined by photo-electric edge sensors and linked cross conveyor
Inventor: GEIGER FRIEDRICH
IPC: D06F89/00
Filed: 1972-12-20
Abstract: After passing through the mangle, the bed linen passes on its conveyor through a longitudinal folding unit, the folded sheet then tripping an end switch which triggers the movement of the photoelectric sensors. As they are moved inwards they stop on reaching the fabric edge, this movement adjusting the lateral position of the second conveyor so that its folding blade is located accurately along the centre line for the cross fold to be effected. System ensures that the cross fold is in the centre of the sheet, without repositioning the sheet for the cross-folding operation.

Title: Direction flow control valve for hydraulic application - spring biased solenoid valve provides 3-way control operation
Inventor: LEIBER HEINZ
IPC: F16K31/06
Filed: 1973-12-20
Abstract: An hydraulic directional flow control utilises a solenoid, comprising a coil and a moving armature to provide connections between three ports. In the stand-by condition the valve poppet is held firmly against output by a coil spring. In this condition a second poppet is clear of the seating. Since the solenoid is not energised the valve is held in the extreme right position by a coil bias spring. When the solenoid is energised a leftwards motion of the moving valve body takes place and second poppet moves against the seating. At the same time first poppet is released permitting a flow path to be established between the second poppet to port aperture.

IPC: E05F15/53
Filed: 1974-03-09
Abstract: The light dome can be returned by the remote actuating system into its normal open or closed position or into its normal partly opened position. This arrangement ensures that the fumes and smoke are removed quickly at the start of a fire in order to prevent asphyxiation and to ensure a clearer view. Subsequently the roof lights are closed in order to prevent formation of draught which will propagate fire. The first lifting element is connected to the free end of a supporting arm whose other end is pivoted on the roof light frame. The supporting arm is actuated by means of a second lifting element with a retracting and extending lifting rod which is conected to the bracket for fitting on the roof light frame. The first extending and retracting element is pivoted on the free edge of the roof light and these two actuating elements can rotate the roof light dome through a full half turn.

Title: Toner density monitor for fluid developer photocopier - has free stream of developer optically scanned via measuring cell
Inventor: SCHLEDERMANN MANFRED DIPL PHYS
IPC: G03G15/10
Filed: 1974-03-30
Abstract: The measuring cell has the fluid developer entering via a jet in the top with the developer directed downwards into a drainage pipe in the bottom of the cell. A lamp is mounted in one end of the cell and a photo-cell in the other. Restricting apertures are fitted to both ends and the cell monitors the light transmitted through the falling stream of developer. The cell thus is unaffected by toner being deposited on the walls of the tubes by measuring the transmittance while the fluid is outside the tubes. The system is powered by a constant flow pump and forms a closed loop attached to the fluid reservoir. When the toner content falls below a set value a metered amount of tober powder is added to the reservoir.
