Title: Crate with corner columns - has locking mechanism allowing wall movement up and down columns only (NL 22.11.77)
Inventor: MARKLUND MARTIN
IPC: B65D6/28
Filed: 1977-05-17
Abstract: The crate comprises a bottom and surrounding walls (1, 2) the latter joined together by columns (3) at the corners. Each column has one or more grooves to accommodate the ends (9) of the walls, also locking mechanisms.

Title: Regenerating magnesium bisulphite soln. for cellulose boiling - by stepwise scrubbing of gases from lye-burning station (OE 15.12.77)
Inventor: SCHROETTNER ERWIN
IPC: B01D53/50
Filed: 1977-06-16
Abstract: Mg(HSO3)2 soln. is produced according to the Parent Patent by scrubbing SO2-contg. gaseous effluents with an aq. MgO suspension in a stepwise process, in which SO2 is gradually removed from the gases. In the first stage the gases are scrubbed with a MgSO3 suspension, whereby Mg(HSO3)2 is formed and removed. In the second stage, the gases, contg now a decreased quantity of SO2, are scrubbed with a MgO suspension; the resulting of MgSO3 is sepd., re-suspended in water and passed to the first stage. This process is improved in that gases from a sulphitelye burning installation are first passed through a dust separator (electrofilter or cyclone) and the MgO-contg. dust is re-introduced into the gas stream before the last scrubber where the MgO suspension reacts with the residual SO2 forming MgSO3. The latter is sepd. from the aq. phase, which is discarded to remove from the circulation impurities resulting from the burning of cellulose fibres, other wood components, fuels etc. The loss of the aq. phase is compensated by addition of fresh water. The recovery of chemicals is increased. The purity of the products is improved and good-quality boiling lye is regenerated.

Title: Conference system for centrally controlled telephone exchange - uses differential amplifiers to eliminate unwanted re-transmissions from subscribers
Inventor: STEUER BERND DIPL ING
IPC: H04M3/56
Filed: 1978-07-25
Abstract: The conference system in a communications facility is esp. a centrally-controlled telephone exchange and has a bus bar (KS) to which subscribers (KT1...KTx) are connected. Each subscriber can communicate with all others through his individual transmission and reception units (SE1, EE1...SEx, EEx).

Title: Prawn shelling machine - with straightening, topping and flesh extracting stations
Inventor: SCHMIDT GEB JAEKEL KARIN
IPC: A22C29/02
Filed: 1978-12-06
Abstract: A machine for shelling of prawns receives the crustaceans through a positioner for a clamp to hold them by the rail. A straightener corrects their curvature before a cutter removes the head. This is discharged and the flesh is extracted in the next station, followed by the disposal of the empty shell. This is the first available machine to replace the conventional manual shelling of prawns. The mechanical method has a high productivity and is pref. from hygienic aspects.

Title: Suspended particles size and/or concn. measuring method - evaluating small angle region of front lobe of light scattered from focused light source
Inventor: GEBHART JOSEF DIPL PHYS DR
IPC: G01N15/14
Filed: 1978-12-09
Abstract: The measuring procedure is for the concn. and/or size of illuminated suspended particles using the dispersed light principle. The particles are illuminated. The illuminating beam is focussed to a point. The particles pass within the region of the focal line. The front lobe of the ensuing scattered light is evaluated in the small angle region. The illuminating beam(1) consists of polychromatic light. The photo-detector consists of a photo-multiplier with wideband spectral sensitivity. To perfect the calibration curve a correspondence between the spectral composition of the light source and the spectral sensitivity of the photo-detector is carried out. A mercury lamp can be used as the polychromatic light source.

Title: Machine for separating coal dust from coal - has rotating framework for removing dust attached to large coal outlet
Inventor: STRAUSS WERNER
IPC: B07B4/02
Filed: 1978-12-28
Abstract: A machine for separating coal dust from small coal has a central tube (9) into which the coal is fed. The larger lumps fall directly into the central hopper (7) whilst the dust is driven by a centrifugal fan (10) into the outer housing (1). This dust is then propelled to the outlet (26) by a rotating framework (13). The rotating framework is attached to a central cone (14) which forms the outlet to the hopper (7). The upper edge of the cone (14) runs in a slot (21) formed around the lower edge of the hopper (7). This construction simplifies the air sealing system on the drive shaft of the rotating framework (13).

Title: Angularly movable rolling bellows for coupling seals - has inner and outer rings held apart by spacers, when preset angle is reached
Inventor: SCHMID LEOPOLD F
IPC: F16J3/04
