Title: Multilayered polyurethane coating for metal surfaces esp. aluminium - with strippable outer layer
Inventor: SIMON GUENTER ING GRAD
IPC: C08G18/32
Filed: 1975-06-28
Abstract: Multi-layered lacquer is predominantly based on polymethane resin layers disposed between two layers of polyurethane resins cross-linked to macromolecular. Between the crosslinked polyurethane layers is an intermediate layer of a linear, noncrosslinked elastic polyurethane which may contain up to 0.1% OH gps. Used for coating onto metal surfaces, esp. outer aluminium surfaces as present in aircraft. When the coating has to be renewed because of wear, only the outer layer need be removed by corrosive chemicals, leaving the undulying layers intact undamaged. Pref. the linear non crosslinked polyurethane resins have a strong tendency to crystallisation, have a Fikentscher K value of 40-65, and are derived from diols modified diols and diisocyanates.

Title: Seven segment optical display unit - has memory component to illuminate selected combinations through decoders
Inventor: MUECKE SIEGFRIED
IPC: G09F9/30
Filed: 1975-07-29
Abstract: The seven segment display unit includes light emitting diodes or glow discharge elements with four vertical and three horizontal sections (a, b... f). The unit is controlled by memory unit (S) connected to two decoders (a, B) one of which (A) is coupled with the desired elements to form the character (b, c, f, g in example, to produce figure 4).

Title: Manually powered propulsion system for water craft - uses submerged flexible foil with reciprocating or waving movement and is suitable for recreational applications
Inventor: GROSSMANN FRANZ-KARL DIPL ING
IPC: B63B35/73
Filed: 1976-05-20
Abstract: The propulsion system for recreational or sporting watercraft is manually powered and employs substantially triangular flexible foils (4) extending downwards normal to the water-plane of the hull (1) which should pref. be cylindrical in underwater shape. One foil edge is perpendicular to the hull centreline, on a spindle (2) about which it can pivot.

Title: Component guide between machine tool and magazine - uses lever arm swivelling against spring force to alternately engage swivelable pawl
Inventor: DOMMANN JUERGEN ING GRAD
IPC: B23Q7/04
Filed: 1976-10-28
Abstract: Guide installation for components operates between a machining station and a receiving magazine, using a carrier slide with chucks to retain the components during transit. One (S1) of the chucks (S1, S2) represents one arm of a lever, whilst the other lever arm (HA), under the influence of a spring (F1) acting in the direction of clamping, is in alternate engagement with a swivelable stop pawl by stops. This is in the area where the components are transferred to the magazine. In the transfer area, the lever arm swivels against the force of the spring and when the stop pawl falls into a contour (VK) of the arm, the arm remains in this position until the pawl comes up to the receiving area stop (AS).

Title: Anti-theft detector for stores - has two inductive loops operated in anti-phase to produce dead zone whose position is varied by de-tuning
Inventor: SCHULZ REINHARD ING GRAD
IPC: G01V3/10
Filed: 1977-04-09
Abstract: The anti-shoplifting alarm for stores detects magnetic markers and consists of two oscillatory circuits, one either side of a gangway or exit, which comprise open coils (2, 2') and parallel-connected capacitors (4, 4'). The resonant frequency of the circuits is in the region of 10 kH. The circuits are energised via switches (6, 6') operated by means of a control unit (8). The switches are operated at 2, 5 kH. Since the coils are excited in opposing phase, the lines of force produce a pattern with a dead zone in the centre line between the coils. In each circuit are additional determining elements (10) which can be switched in and out of circuit so that the blind spot between the coils is continuously shifted.

Title: Sump-phase hydrogenation of coal in fluidised bed reactor - with recycling of product after partial sepn. of solids
Inventor: CHERVENAK MICHAEL C
IPC: C10G1/08
Filed: 1977-08-18
Abstract: Coal is hydrogenated by grinding to below 1000 mu m, mixing with oil to a slurry contg. 30-50% solids and passing upwards through a fluidised bed hydrogenation zone contg. catalyst, under 100-300 atmos. pressure. Content of liquid residue in the reaction zone is kept at 30-45 wt. % and that of unconverted solid at 10-25%, by (a) passing the product through a phase separator operating at 90% min. of the reactor pressure and near reaction temp., (b) dividing the liquid product into two streams, (c) removing solids from one stream in a separator operating at 90% min. of reactor pressure and near reaction temp., (d) mixing the liquid stream with the untreated stream from (b) to give a solids content of 5-15 wt.%, and (e) recycling the mixt. to the reactor. By carrying out the partial sepn. of solids at near reactor temp. and pressure, sepn. is improved by the lower viscosity and the costs of reheating and compressing before recycling are reduced.

Title: Light soil structure improver prepn. - from aluminium industry waste by treatment with alkali silicate, then neutralising
Inventor: HERGENHAN HARTWIG DIPL PHYS DR
IPC: C09K17/12
Filed: 1977-08-29
Abstract: Method for preparing an agent for structural improvement of the physical and physico-chemical properties of light soils comprises reacting waste slurry from the Al industry (made by alkaline decompsn. of Al-contg. ores for alumina recovery) with 0-50 (3-30) wt.% (dry basis) of Na or K silicate soln. The mixts. is then neutralised to Ph 7-8 with H2SO4, H3PO4 and/or HNO3. Alternatively urea is added instead of the mineral acids. Opt. to improve the absorption capacity of the treated slurry 0-50 (0-20) wt.% of an alkali aluminosilicate, obtd. by decomposing alumina with Na or K hydroxide is added. Also, after neutralisation 0-0.5 wt.% dry basis of an alkaline (esp. NH3) soln. of polyvinylalcohol and borax (wt. ratio 15:1) is added. The compsn. improves the absorption and water-retaining props of the soil; provides some nutrients; and when, used with fertilisers, herbicides, pesticides etc. provides uniform distribution of these cpds. The process eliminate the high alkalinity of (I) and prevents the conversion of phosphates to useless, insoluble Fe and Al salts.

Inventor: HOFMEISTER HELMUT DR
IPC: C07J1/00
Filed: 1977-10-31
Abstract: Prodn. of DELTA15-steroids of formula (I) comprises ethynylation of a 17-oxo-steroid of formula (II): In the formulae R is H or acyl, and A-B is carbon-carbon double bond or the grouping -C15(OR1)-C16- in which R1 is H or a silyl, acyl, sulphonyl or nitro gp.

Title: Steam and dry smoothing iron - has locking mechanism holding water valve open released by pressing central button
Inventor: RADER ARMIN ING GRAD
IPC: D06F75/18
Filed: 1978-01-10
Abstract: The manipulation of a steam and dry smoothing iron is simplified as regards the changeover from steam to dry ironing. The iron described in parent patent has a rotary adjusting disc for the temperature of the sole, above which there is a water reservoir. A valve stem can be moved by a push button into an open or a close position, and the push button for the valve stem is linked to the temp. adjuster, so that it can only act on the valve stem to open it and be locked in the open position when the temp. is set for steam. The modification makes it unnecessary to adjust the temp. when changing to dry ironing, since the locking of the valve in the open position is cancelled by manual pressure on the central operating button.
