Patent DE-2358200-A1 (DE)
Title: Collection of fractions in liquid stream - using open or closed trough with vessels fed from it
Inventor: GROOD MELCHIOR ANTONIUS DE
IPC: B01D5/00
Filed: 1973-11-22
Abstract: Liquid streams which contain successive fractions of different compsn. which must be collected and kept separate, can be so collected by using a trough which runs at a level above a series of vessels which have inlets running off the trough. As the liquor flows along the trough, the first vessel is filled until it will take no more liquid and then the liquid flows on along the trough until the next vessel begins to fill. So successive vessels are filled in turn. The trough can be horizontal or can be slightly downwards inclined (i.e. =30 degrees, esp. is not >15 degrees) in the direction of flow. The method is esp. applicable to mass transfer operations, esp. ion exchange processes.

Title: Treatment of waste water from coke oven gas desulphurisn.
Inventor: DIEMER PETER
IPC: B01D53/48
Filed: 1973-12-13
Abstract: In a process for the desulphurisation of coke-oven gas by scrubbing with a soln. contg. oxygen carriers (e.g. equiv. ones), the waste water is treated by (a) evaporating it to remove 30-70% of its H2O; (b) injecting the concentrate into a combustion chamber where it is decomposed, with simultaneous injection of air, in a reducing atmosphere produced by burning coke-oven gas and NH3, vapours (from the gas treatment) with less than the stoichiometric amt. of air; (c) utilising the sensible heat of the resulting lean gas to generate steam and evaporate a new batch of waste, water, and then adding the lean gas to the coke-oven gas, together with the steam from stage (a), upstream of the precondensers; and (d) separating the S form the lean gas. The pollution problems associated with waste water disposal (i.e. the fraction of recycle scrubbing soln. periodically withdrawn for replacement by fresh soln.), which contains thiocyanate sulphates, thiosulphates, etc., and has a high oxygen demand, are avoided, and the NH3 vapours from the gas treatment are eliminated at the same time.

Title: Advancing tunnel supporting framework - has hydraulic vertically adjustable columns coupled together by horizontal beams under roof
Inventor: MAYKEMPER ALFRED
IPC: E21D23/00
Filed: 1973-12-20
Abstract: The structure comprises four coupled frames each with two columns located on the gallery face. The columns are connected to the transverse beams via a hinge coupling. Two of the frames are connected together to the one frame combination by top traverses and mechanically extendable spacers while the other two frames are similarly connected by further top traverses and spacers. Each of the two top traverses consist of two double jointed sections. When viewed in plan view the parallel rows of traverses are arranged with two capping sets alternating with one another and displaced longitudinally so that at one end of the structure the tips of one set project forward of those of the other set. The frame combinations can be displaced along the gallery by upper and lower cylinders coupled between them.
Patent DE-2404228-A1 (DE)
Title: Bimetallic backing ring for piston rings - backing ring maintains constant contact pressure over temperature range
Inventor: SEIFERT GERD W DIPL ING DR ING
IPC: F16J15/3212
Filed: 1974-01-30
Abstract: Linear motion takes place between a piston sliding in a cylindrical bore. A split piston ring is located in a groove around the periphery. Normally contact between the ring and the cylinder walls depends upon the spring characteristic of the ring. In this instance a bimetallic ring is located in the groove behind the piston ring. One end of the bimetallic ring is turned over to locate in a notch in the piston ring so as to prevent rotation. The characteristics of the bimetallic ring may be matched to a particular temperature range to ensure that piston ring contact pressure is maintained essentially constant.

The threaded ball assembly is pushed through a pipe which is parallel to the feeder tube and the tube for actuating elements has a bend so that the other arm of this tube is in line with the feeder tube. The bar pushing element is actuated by a power driven belt system. This actuating arrangement can be connected to feeder tubes with different diameters, and noise damping springs can be fitted into this feeder arrangement.

The support frame may comprise a base plate with threaded bolts which carry adjustable units supporting the vibrator. The outlet channel for the container extends tangentially at the upper end of the helical channel on the container inside surface.
Patent DE-2517838-A1 (DE)
Title: Spring ski braking device - has convex spring plate to operate brake automatically when boot is removed
IPC: A63C7/10
Filed: 1975-04-22
Abstract: A spring steel convex foot plate fits into the upper ends of the brake plates so that when the boot is in position on the ski the foot plate is flattened, thus turning the braking plates round a hinge on the brake axle to stow the brake plate on the upper surface of the ski. When the boot is removed from the ski, the foot plate returns to its bowed formation thus swinging the brake plates over the side of the ski and allowing the torsion spring, which is wound round the brake axle with one end under the brake plate while the other end is held against the axle base plate, to push the brake plates into the braking position bringing the ski to a halt when the ski is lost from the boot is an accident.

Title: Coating concrete mouldings with glass or phosphate - by adding a salt to the concrete applying coating paste and curing
Inventor: KREJCI MILAN DIPL ING
IPC: C04B41/67
Filed: 1975-09-06
Abstract: A freshly moulded concrete block made from a mineral binder and a classic granulate is coated with an aq. paste contg. a soluble glass and/or a phosphate, together with a metallic oxide, at a rate of 190-400 g/m2, in the presence of soluble mineral salt(s). The salt(s) are present at >=0.5 wt.% of the mineral binder content. In the case of sand lime bricks the salt(s) are present in an amt. related to the sum of the bind and granulate. The mineral salt gels the paste allowing it to be hardened at the same time as the concrete. Process is less costly than separate curing of the concrete and the coating.
