Patent DE-2167008-A1 (DE)
Title: Counter control circuit for profile measuring equipment - uses detector output connected to inverting AND gate and has input connected to gate counter
Inventor: KALLINA INGO DIPL ING
IPC: G01B11/28
Filed: 1971-07-09
Abstract: The counter control circuit is used in conjunction with a laser-operated profile area measuring equipment for determining aerodynamic properties of moving vehicles. The circuit uses the synchronising pulses from the stepping-motor drive as direct timing pulses for the counter gating. The clock pulses (34) are fed to one input of an AND-gate (31). The AND-gate has a second, inverting input (33) which is connected to the output of the photo-detector (28) which responds to the illumination of the laser beam as it scans the object under investigation. When the beam is broken by the object, there is no output from the detector and the AND-gate allows the clock pulses to be registered by the counter. When the detector conducts, the AND-gate is inhibited and the count is frozen.

Title: Moulding rigid resin foam plates - by uniformly heating in closed air circulation oven
Inventor: BRUECHMANN PETER
IPC: B29C44/56
Filed: 1972-02-11
Abstract: Rigid resin foam plates e.g. of foamed methacrylic acid methacrylonitrile copolymer are moulded by placing the plates in a closed (air circulation) oven, and applying a uniformly distributed (penetration) temp., whose elevation permits a plastic deformation of the foam. Specif., the uniformly heated plate is curved under continuous pressure between male and female mould halves while in the oven. Moulding is effected under the simultaneous action of an additional elastic force leading to a positive combination of the mould halves after the foam is softened. Efficient uniform heating enables the foam plates to be rapidly moulded.

Title: Rigid foam (relief) metallisation - by electroplating with copper and decorative metal,for lightweight panels
Inventor: KLEPEK MONIKA
IPC: B44C1/04
Filed: 1972-03-04
Abstract: Rigid foam relief and plastics are metallised by electrolytic deposition of (a) a (Cu) base coat in any thickness and then (b) a metal "decorative" coat, e.g. of Ag, Au, brass of bronze etc. followed by chemical after treatment, to patinate the surface. The construction is lighter than solid metallised plastics and has the same appearance, durability and strength. Large relief panels can be fixed to walls of rooms, since the prods. have great stiffness and static strength. A PUR integral rigid foam is prefd. After patination, a protective lacquer coat (cellulose ester varnish) can be applied.

Title: Paper pulp sizing - with aq dispersions contg reactive monomer with no salts
Inventor: SCHARF EMIL DR
IPC: D21H17/37
Filed: 1972-08-22
Abstract: Paper fibres are bonded in absence of metallic salts at pH 5-9 pref. 6-8 using anionic polymer dispersions by polymsn. with a hydrophobic monomer in aq. medium in presence of emulsifiers contng. COOH gps., where the dispersions contain particles of mean size 200 nm and having Tg. 70 degrees C. Monomers are e.g. (meth)acrylic acid esters with >3C alcohols, or vinyl aromatic cpds. Emulsifiers are salts of (iso) fatty acids or resinic acids and their hydrogenation/disproportionation products or ethylene or diene reacted with maleic acid derivs. The process prevents growth of algae and deposits of adhesive and foaming. Corrosion is also reduced because the soln. is at near neutral pH in absence of salts.

Title: Polyurethane foam shell moulding - by spraying mesh foundation clad with polyethylene film
Inventor: RUHNAU JOACHIM
IPC: B29C44/12
Filed: 1972-09-04
Abstract: The polyurethane is sprayed or injected into the mesh foundation, of wire netting or braiding or honeycomb of suitable metals or plastics or paper. The foaming action forces the polyurethane through the openings to encapsulate the foundation, the polyethylene film giving it a smooth surface. The polyurethane can be pulled from the foundation leaving it in the moulding zone, for the film to be peeled off, giving individual shells or a continuous prod. for cutting, for use in boat building or construction applications.
Patent DE-2243672-A1 (DE)
Title: Continuous prodn of pigment - liquid mixts - esp for printing inks, by screw-feeding solids and liquids separately to a rotary mixing head
Inventor: ZUCKER FRIEDRICH J DIPL ING
IPC: C09D11/02
Filed: 1972-09-06
Abstract: The solid components are fed by a hollow screw and the liquid components passed through the middle of the screw, to the centre of a rotary mixing head of the rotor-stator type. These interact to produce shear, vibration and cavitation forces, which immediately cause dispersion of the pigment and homogenisation. Further liquid additives may be introduced radially to the mixing head, pref. after the first rotor-stator system. Since mixing occurs within a fraction of a second of first contact between solid and liquid, formation of aggregates which are difficult to disperse is prevented. High output rates are obtained from equipment of relatively low cost.

Title: Plastics water closet bowl with flushing rim - has circumferential internal flushing gap of variable width
Inventor: CAPPEL HERMANN-JOSEF
IPC: E03D11/02
Filed: 1974-01-21
Abstract: The plastics water closet bowl has an inwards folded top rim which forms a flushing water conduit. The rim lower edge forms a gap with the bowl wall for water outlet. The conduit and outlet are formed by placing a moulded curved variable width channel shaped ring on top of the moulded plastics bowl edge. The conical adhesive bonded joint between the ring and bowl ensures that tolerances do not affect the flow gap size. The water enters from above into flushing water entry channel, and the inverted rim channel forms a water outlet gap with the bowl wall. This gap is narrowest at the water inlet and its width increases to its maximum at the front of the seat. The gap size ensures laminar flow of water into the bowl.

Patent DE-2435244-A1 (DE)
Inventor: SCHOENBECK RUPERT DR
IPC: C07D237/14
Filed: 1974-07-22
Abstract: The compounds of the formula I in which R and R' have the meanings given in Patent Claim 1, are prepared by reacting a suitably substituted ester of 3-benzoylacrylic acid with more than 1 mol of hydrazine per mole of ester, and subjecting the resulting reaction mixture or the isolated intermediate to an acid treatment at increased temperature. The reaction in which cyclisation to give the pyridazone takes place is surprising since it is known that benzoylacrylic acid is present in the trans form, and trans-1,4-carbonyl compounds generally do not undergo cyclisation with hydrazine to give a pyridazine ring. The 3-phenylpyridazones are suitable as intermediates for the synthesis of pharmaceuticals and crop protection agents. <IMAGE>
