Title: Monitor for electricity meter with static measurement unit - delivers reference signals of desired amplitude and frequency to multiplier circuit supplying comparator
Inventor: SCHEEW PETER
IPC: G01R11/25
Filed: 1977-08-24
Abstract: A monitor circuit for an electricity meter with static or electronic measurement unit contg. an analogue voltage multiplication circuit is designed to detect indication errors caused by errors in component parts. This is achieved with low production and installation costs. The monitor circuit delivers reference signals of defined amplitude and frequency to the multiplier circuit. The product is fed to a reference signal comparator circuit with another input from a test signal generator providing a desired value signal. The comparator output adjusts the mechanical indicator mechanism via a stepper motor to correct for errors.

Title: Temporary cover plate for large duct openings - has hinged plate with rectangular access hole and door
IPC: B65D90/10
Filed: 1977-09-09
Abstract: During interior maintenance work on large vessels such as heat exchangers of nuclear reactors, the openings to supply and discharge ducts may be blocked by the use of this folding cover plate. It consists of a flat circular disc cut along a diameter into two parts (21, 22) and having a rectangular cut out in the middle, with its long edges parallel to the dividing diameter. Hinges (20) are provided at each end of the diameter, connecting the two halves together. The rectangular cut out provides an access hole which is covered by a removable door (23) fitted with longitudinal edge stiffening ribs and handles. Stiffening ribs on the cover plates are fitted parallel to the cut out edges and serve also as guides for centralising the door. A sealing membrane attached along the long edges of the cut out extends to cover the hole automatically when the plates are hinged out to seal the duct opening.

Title: Sunblind inward bending hinge arms - have one swivel axle movable vertically to drop direction, with prestressing
Inventor: LATTEK SIEGFRIED
IPC: E04F10/06
Filed: 1977-09-29
Abstract: The awning sunblind has two double-shanked hinge arms which can be bent in towards each other, with open ends hinged to swivel about vertical axes firstly in the area of the canvas and secondly on the drop rod. One swivel axle (13) on one hinge arm (6) is mounted so as to be displaceable vertically to the line of drop in the plane of the arms (6, 7). In the swung-out position it is prestressed into a position deviating from the bent position, by means of stressing media (16). A spring may be used for prestressing the hinge axle to the other arm. This enables long arm to be bent inward, where the interval is small.
Patent DE-2744631-A1 (DE)
Inventor: ITEN WALTER ALOIS
IPC: B41C1/14
Filed: 1977-10-04
Abstract: To provide a particularly advantageous web formation, the screen-printing screen is provided with a periodic perforation pattern whose pattern period has a regular hexagon which is surrounded by pentagonal holes which are offset relative to one another by 60 DEG  in each case. In this case, a side of equal size of one of the pentagonal holes lies opposite each side of the hexagonal hole. The sides of the pentagonal holes facing one another each run parallel to one another. The sides of the pentagonal holes adjoining these sides running parallel to one another are flush with one another in each case so that the outer contours of the total of six pentagonal holes surrounding the regular hexagon in turn form a regular hexagon. By this arrangement, webs of absolutely identical width are formed both between the pentagonal holes themselves and between the hexagonal hole and the pentagonal holes and between the individual pattern periods themselves. <IMAGE>

Title: Gypsum prodn. in a compact plant - by oxidn. and sedimentation of wash liquor from sulphur di:oxide gas scrubber
Inventor: HOELTER HEINZ
IPC: C01F11/46
Filed: 1978-01-11
Abstract: Oxidn. and sedimentation of recycled wash liquor media from a (SO2) gas scrubber involves admitting air to the liquor in a flat oxidiser in the inflow region and pumping the liquor back to the oxidn. zone near the air inlet from the following quiet zone. Milk of lime is added after the quiet zone and the CaSO4 slurry formed is transferred from the flat oxidiser by means of a scraper flight conveyor to the flat sedimentation vessel, from which the settled gypsum crystals are conveyed by means of a scraper belt to a mixer where additional acis is added. The slurry is sepd., pref. in a centrifuge, and the sped. liquor is passed to neutralisation, a ditch or the wash liquor for the renewed charge. The end prod. is saleable gypsum. the process gives very good oxidn. and sedimentation using small vessels.

Title: Electrolytic capacitor in metal casing - with collar and enlarged diameter on anode pin for better sealing of elastic plug
Inventor: GRUNERT ALFRED
IPC: H01G9/008
Filed: 1979-01-18

Title: Energy recovery during glass melting - where waste combustion gas flows through recuperator to heat air used to burn fuel, and then directly preheats pelletised glass batch
Inventor: PELZER R DIPL ING
IPC: C03B3/02
Filed: 1979-02-10
Abstract: The glass is melted via heat obtd. by burning oil, gas or other fuel, with a continuous stream of air for combustion. The waste gases are first used for (I) recuperative heating of the air; and then (II) preheating the glass batch by direct heat exchange. Preheating (II) pref. occurs by feeding the waste gas in counter current to the batch, which has previously been compacted, esp. as briquettes, and falls via gravity towards the melting furnace. The pref. plant consists of a glass melting furnace fitted with a recuperator located directly adjacent to at least one preheater through which the glass batch travels. The preheater consists esp. of a vertical shaft with a bottom inlet for waste gases leaving the recuperator. The waste gas temp. can be lowered to 200-300 degrees C. by the above steps (I, II) so a large amt. of energy is recovered.

Title: Non-essential aminoacid(s) e.g. phenyl-glycine, separation - from derivatives e.g. ester(s), by electrodialysis at pH 4-8
Inventor: PERRY MORDECHAI
IPC: B01D61/44
Filed: 1979-02-26
Abstract: An aq. mixed soln. contg. a non-essential aminoacid and a deriv. of this acid in ionic form is sepd. by electrodialysis into 2 separate prod. solns. in form of acid and deriv., of which 1 comprises a high purity prod. obtd. in high yield. The concn. and feed rate of the mixed soln. supplied to the electrodialysis cells and the applied electrical current density are controlled such that concn. polarisation conditions are produced at the cell membranes so that high localised concns. of protons and OH ions accumulate on the surfaces of the anion- and cation- exchange membranes, respectively. The pH of the total soln. in the cells is held at 4-8, independently of the isoelectric point of the aminoacid, in order to counterbalance pH changes of the total soln. which occur as a result of different extents of water decomposition at the cation- and anion- exchange membranes.
