Patent DE-2511453-A1 (DE)
Title: Roughness determin of yarns - using micrometrically adjustable piezo-electrical element to set up resonance
Inventor: KENK THEO
IPC: G01N33/36
Filed: 1975-03-15
Abstract: A device for determining the roughness caused by fibres protecting from the surface of a yarn adjusts the proximity of the sensing organ to the yarn by means of a micrometric screw or an eccentric disc, or some other mechanism. For the various gauges of yarn, the sensing organ (2) is adjustable at the necessary distance from the diameter of the yarn sample, and the number of fibres projecting through the distance set, is ascertained. The yarn may run over a fixed solid surface which can be displaced to and from the sensing organ, or its line of motion may be located between two opposing and mutually adjustable sensing organs. A special form for the sensing organ copes with the resonances set up and the degree of roughness of a yarn can be compared with that of others.

Title: Collision protection for pedestrians - with inflatable retaining barrier along edges of bonnet operated by contact sensor
Inventor: HENSLER PAUL DIPL ING
IPC: B60R21/34
Filed: 1975-04-05
Abstract: The front edge of the car bonnet is provided with a slot into which is fitted a folded airbag (B) to lie flush with the bonnet surface. The slot and airbag are taken round the side edges of the bonnet as well. If a pedestrian is struck by the car, a sensor (13, 10) releases the compressed air from a gas bottle (7) to inflate the airbag. The inflated shape of the airbag forms a ledge around the front and side edges of the bonnet and prevent the pedestrian from sliding off. The system is simpler than a mechanical barrier, and when stored forms a smooth fitting with the car shape. For additional security the bonnet surface is roughened.

Title: Piston pipette, after Eppendorf - for small liq. vols., having two return springs, with adjustable travel for calibration
Inventor: BAUER HORST
IPC: B01L3/02
Filed: 1975-08-04
Abstract: The pipette has central co-axial rod having a piston formed by a sealing ring at one end which slides inside a tube to draw in or expel liq. the other end carries a handle by which the pipette is actuated. A first stop on the rod compresses a first spring against a shoulder in the housing when the rod is pushed in. A second stronger spring is compressed against another shoulder in the housing by a stop which can slide along the shaft. Its movement is limited at one end by the first stop. The sliding stop is made to move by a third fixed stop on the shaft after the first spring has been partly compressed and thereby compressed the second spring. According to the novelty, the third stop is formed by a nipple which is screwed into part of the housing to a distance which can be set according to the vol. of liq. to be measured. The piston formed by the sealing ring is designed for sealing and expulsion of the liq. but not as part of the vol. of the pipette. The pipette is equal in precision to but cheaper than previous versions. No retraining of personnel is required. The pipette vole. can be inscribed on the tube inside the housing after calibration and is protected from abrasion.

Title: Regenerating spent alkylation catalyst - contg fluorosulphonic acid and sulphuric acid used for branched paraffin prodn
Inventor: LINE JUN LLOYD ERNEST
IPC: B01J27/32
Filed: 1975-10-25
Abstract: Recovery of fluorine cpds. from a spent alkylation catalyst contg. fluorosulphonic acid and sulphuric acid is carried out by adding to the spent catalyst water in an amt. at least sufficient to hydrolyse the fluorosulphonic acid to HF (pref. 3-15%); then subjecting the mixt. to distillation at normal or reduced press. (pref. =0.07 atm.) at 50-120 degrees C. (pref. 80-110 degrees C.); collecting a first fraction consisting mainly of HF; isolating as a second fraction the distillation residue contng. the remainder of HF and/or other fluorine cpds. and most of H2SO4 present in the spent catalyst body; converting the HF contained in the first fraction back into fluorosulphonic acid by treatment with SO3; contacting the second fraction with alumina to absorb HF and/or other fluorine cpds., or with silica to form SiF4 which is evapd.; subjecting the residual liq. contg. most of H2SO4 to evapn.; oxidising the resulting SO2 to SO3 and absorbing the latter in conc. H2SO4 which is subsequently diluted and used together with the regenerated fluorosulphonic acid to produce fresh alkylation catalyst. Used for the prodn. of branched 7-8C paraffins having a high octane number by reaction between iso-paraffins (isobutane, isopentane) and olefins (propylene, butylene) in the liq. phase in the presence of a catalytic system contg. SO2F(OH) and H2SO4. The catalysts are easily regenerated by the above method.

Title: Radome for arctic conditions - has heating elements embedded in laminated material with inductive compensation for its capacitance
Inventor: BRUNNER HEINZ
IPC: H01Q1/02
Filed: 1975-11-15
Abstract: The radome is used on ships in arctic conditions. An electric heating element is fitted close under the radome surface or embedded in the Radome material. Heating wire is laminated in the Radome material. Where more than one element is involved, they are made independent of polarity by being designed in strips of parallel wires which intersect at right angles to form a grid. The inductance of the heating wire is chosen to compensate for capacitance of the Radome material by relating the distance between the wires to the wall thickness and the dielectric constant of the Radome material.

Title: Sailing craft with pivoted mast - has universal joint at mast base to counteract heeling over
Inventor: GUTJAHR RAINER
IPC: B63B35/79
Filed: 1976-03-06
Abstract: The recreational sailing craft with the mast mounted on a universal joint (11) is a catamaran with a sailboard-style sail plan with a double boom (14). The mast mounting (9) is on the braced platform (3, 6) connecting the hulls (2), on the centreline and roughly at mid-length of the craft. Compared with an ordinary sailboard this not only makes it more stable but also makes it easier to counter the heeling moment of the sail by crew weight. The centreboard (10) can be on the craft centreline, or smaller boards can be fitted to the hulls. Mast height roughly equals the craft length. Instead of the catamaran a single hull with an outrigger can be used. The mast is then mounted on the hull centreline.

Title: Removal of ammonia from effluent waters, e.g. from coking plant - by treating in a column with milk of lime, removing ammonia with a hot gas stream and burning the lime sludge
Inventor: HAESE EGON
IPC: C01C1/10
Filed: 1977-02-09
Abstract: Process for expelling ammonia from an ammonia-contg. soln. which has been treated with milk of lime in an expulsion column and from which the ammonia has been driven out with a hot gas, steam or vapours, comprises drawing off a bottom prod. contg. lime sludge, calcium sulphate, unused hydroxide, calcium carbonate and other calcium compounds and passing this to a settling unit in which the sludge is separated from the liquid.
