Patent DE-2050148-A1 (DE)
Title: Mosaic facing plates - for building trade
IPC: B28B19/00
Filed: 1970-10-13
Abstract: The light weight mosaic faced building components in plate form etc. are manufactured by a process involving the glueing down face downwards of glass, ceramic, or natural stone mosaics to a suitable paper or similar carrier foil taking care that the mosaics are correctly spaced to leave fixing gaps for the self hardening material paste which is poured over the mosaics resulting in the formation of an integral component with a mosaic facing. The backing/setting material may be concrete or epoxy resin. The thickness of the backing is increased towards the suitably profiled edge. The method ensures a flat mosaic surface and requires little skill.

Title: Self alignment of billets - on rocker bar grate
IPC: C21D9/00
Filed: 1970-12-19
Abstract: Rocker bar grate for feeding rolling mill furnaces suitable to be charged by either placing upon it ingots in haphazard stackes or (e.g. when using a magnetic hoist) ingots already arranged in a single layer side by side across the direction of travel, obviating different types of grates as hitherto for each charging method. A passage block placed across the rocker bar grate width leaves sufficient clearance for ingots to pass through in a single layer, while pushing off the ingots stacked upon this bottom layer on to the grate to pass eventually in a single layer. In this grate area, the rocker bars are provided with blunt serrations across their top surfaces. A height adjustable alignment plates fixed to the grate frame with an inclined receiving surface of height exceeding that of the rocker bars in their up posn follows which, while allowing out of line ingots to slide over it, turns them to lie across the direction of travel. Ingots already aligned by the use of a magnetic hoist may be placed on this layering and alignment grate section, or behind it, closer to the furnace mouth.

Title: Separation of vent gas from ammonia synthesis process - into hydrogen-rich and argon-rich fractions
Inventor: LINDE GERHARD DIPL PHYS DR ING
IPC: F25B9/04
Filed: 1973-09-26
Abstract: Vent gas from the NH3 synthesis process is separated into a hydrogen-rich fraction and an argon-rich fraction by passing through an inlet nozzle (e.g. Laval nozzle) into a Rangue-Hilsch vortex tube. The inlet nozzle reduces the pressure from the synthesis presure to sub-critical press. The hydrogen rich stream may be wholly returned to the synthesis process or partly used as fuel. Argon is recovered from the argon-rich stream in a cryogenic separation plant, which also recovers the nitrogen in the stream for re-use in the synthesis is process or for nitrogen-washing of the synthesis gas. (1) Improves economics of the synthesis process. (2) The process is more economical, and reduces the energy requirement of the Argon recovery system.

Title: Screen cloth wear monitor - by incorporating electrically conductive threads which form part of resistance measuring circuit
Inventor: LESK ADOLF
IPC: B01D35/14
Filed: 1974-09-11
Abstract: The wear of screen and filter cloths, used for the screening of bulk materials with a mixture of coarse and fine particles can be monitored by embedding in the fabric an electrically conductive check wire. The latter is a part of an electrical circuit with an ammeter and a current source to measure its electrical resistance which is a function of the growing wear. This gives adequate warning of impending damage and prevents fines becoming mixed with coarse overflow in case of unexpected screen cloth breaks.

Title: Large fan blade of reinforced castable resin - is cast in mould inside vacuum chamber to eliminate gas inclusions
Inventor: FRANK KARL
IPC: F04D29/02
Filed: 1974-09-12
Abstract: A method of making a reinforced (synthetic) resin blade for a fan or blower consists of wrapping a core with reinforcement e.g. glass fibre, inserting it into a mould, and introducing liq. castable resin mixt. into the mould, using a pressure difference created by a vacuum inside the mould. A fusible core is pref. used, so that it melts, leaving a cavity in the blade. Esp. for very large blades, for impellers of several metres dia. The use of vacuum inside the mould, coupled with a pref. fusible (e.g. wax) core, instead of a foam core, minimises gas inclusions in the casting, thus giving improved strength to withstand centrifugal forces. The leading edge of the blade can be integrally cast with the remainder, but with additional reinforcement on the inside.

Title: Measurement of dust content in moving gases - involves monitoring current discharge through corona discharge electrodes
Inventor: SCHIRMER GUENTER
IPC: G01N27/70
Filed: 1974-09-20
Abstract: The dust content in flowing gases, specially the soot content in exhaust gases of Diesel engines and flue gases from oil-fired boilers, is measured by passing the gas (10) between a first pointed electrode (11) and a second planar electrode (12). A high d.c. voltage is applied between the electrodes to produce through the electric field (13) a corona discharge. The difference in the currents (i1-i2), which corresponds to the charges carried away by ions adhering to dust particles and is proportional to the dust content, is measured. If a third (earthed) electrode (16) is arranged as a collecting electrode, the current i3 can be measured and regarded as proportional to the dust content.

Patent DE-2449355-A1 (DE)
Title: Separation of suspensions by oscillation - using variations in kinetic energy to separate into zones of concn
Inventor: HESS BERNHARD PROF DR
IPC: B01D49/00
Filed: 1974-10-17
Abstract: Suspensions are separated into their components by transmitting kinetic energy to the suspended component by a non-uniform movement of the suspension, e.g. an oscillation. This produces a degree of relative motion between the suspended material and the medium, causing changes in concentration which are used to purify the medium. Zones with increased mean energy are coupled with one or several zones where the suspended material has reduced energy and it can move from the areas of high energy to those of lower energy. Standing waves can be used to creak these areas of high and low energy. This can be done by moving the vessel in which the suspension is by direct force on it or alternatively by using sonic, ultrasonic or infrasonic waves on the suspension. The device is useful to separate two-phase systems, such as aerosols or lysols.
