Title: Magneto strictive transducer for immersion in liquid sodium - has coil assembly elastically mounted in hosing to damp out stray vibrators causing false signals
Inventor: KNAAK JOACHIM DIPL PHYS DR RER
IPC: G01H11/04
Filed: 1975-09-18
Abstract: The magnetostrictive transducer, to be immersed in liq. sodium, has a rod-shaped ferromagnetic core whose axial stress is translated into a voltage in a coil wound around it.

Title: Fractionation column for removing monomer from polymer suspensions - which extracts volatiles while avoiding sedimentation
Inventor: KUXDORF BERNHARD DIPL ING
IPC: B01D3/22
Filed: 1975-11-07
Abstract: A multiplate cascade column is for degassing a liquid contg. solid particles in suspension. Each plate is perforated with small holes (=5mm dia.) except for regions beneath tubes linking successive levels and for a narrow gap between each plate and the column walls. The link tubes are positioned eccentrically with respect to the column/plate axis. Device is suitable for separating residual monomers from polymer particles in a suspension, esp. for removing vinyl chloride from an aq. suspension of PVC contg. 1-60, pref. 20-40% wt. polymer. The free area at each plate level is relatively low, i.e. =8, pref. >=6% of the gross area, for operating efficiently at low gas loadings. At the same time the design avoids corners etc. on which the solid particles could settle out and build up. The liquid layers are universally agitated by the gas flow through the perforated plates, to sustain the suspension.

Title: Locking device for self cleaning oven door - is operated by bimetal strip and thermostatically controlled blocking motor
Inventor: HELLMANN DONALD
IPC: F24C15/02
Filed: 1976-02-13
Abstract: The door (2) of an oven (51) is locked shut during the high temperature cleaning process. The door has a bar (91) on its back in which there is a slot (912). A bimetal strip (94) receives heat from the inside of the oven through a conducting pin (942) in the top of the oven. A hook (941) on the end of the bimetal strip engages in the slot (912) in the bar on the back of the door and prevents the door opening. A thermostatically controlled motor (96) drives a camshaft (961) which depresses a pin (943) belos a predetermined temperature. The pin deflects the bimetal strip and thus prevents the hook on its end locking the door the predetermined temperature.

Title: Counterflow extraction tower for sugar beet shreds - with cleaning strips between shred distributors sweeping over annular screen deck
Inventor: STRAUBE ELMAR
IPC: C13B10/10
Filed: 1976-04-23
Abstract: A vertical tank for the counterflow extraction of vegetable substances consists of the outer shell which forms with a rotating centre tube an annulus, covered by a screen deck. Shredded beetroot distributor arms fixed to the central tube are sepd. by cleaning strips which scrape over the screen deck and remove pulp and dirt particles from the screen. These particles are collected and discharged by a device which retains the extraction juice. This saves downtimes and prodn. loss caused by clogged screen decks. The shredded beetroot particles pass over the inclined face of the cleaning strip. The dirt/pulp particles are not pressed into the screen openings but scrapped clear. The sugar yield is increased and the capacity of the extraction tank is utilised to a greater degree.

Title: Preparation of transparent artwork - by exposure to actinic light and layer to layer removal of material to form mask
Inventor: BEREZIN GENNADY NIKOLAEVITSCH
IPC: G03F1/00
Filed: 1976-06-11
Abstract: Transparent artwork is formed by taking a substrate transparent to actinic light and a masking layer translucent to actinic light is formed in the near surface portion of the substrate, and a predetermined topological relief pattern is made by local layer to layer removal of the material on the side of the masking layer, with concurrent measurement of the optical phase difference between light rays passing through the masking layer and transparent portions of the artwork until the geometrical relief of the pattern becomes deep enough to ensure an optical phase difference which is a multiple of 2 phi. Method may be used for preparing artworks employed in photolithography for making thin film and integrated microcircuits. Method ensures high stability of photo lithography using transparent artworks, broadens the range of operating exposures, renders the optical density of masking coatings less critical, and provides for reproducibility of the optical characteristics of artworks.

Title: Metering arrangement for multicomponent filler materials - has channel plates with different size flow paths for each component
Inventor: WOLL BERNHARD
IPC: B05C17/10
Filed: 1978-06-07
Abstract: The metering arrangement for e.g. a two component filler material ensures that the prescribed volume ratio of the components and hardener in the mixture is accurately controlled. A separate feed channel is used for each component. The ratio of the cross sections of these channels corresponds to the specified ratio of the components. The arrangement consists basically of metering plates with separate feed channels for the components, separated by partitioning walls on a plate. The cross sections of these channels can be varied by a member moved in a transverse direction into a channel. The bottoms of these channels are formed by the metering plate and their upper faces are open. The channels are protected against entry of dirt by covering hoods.
