Title: Iron mfr. from iron oxide(s) - where spent active carbon or charcoal is used as inexpensive reducing agent replacing coke
Inventor: MINDERMANN FRITZ DR RER NAT
IPC: C21B13/00
Filed: 1979-08-24
Abstract: Parent patent described the mfr. of iron by reducing iron oxides with carbonaceous waste, e.g. sewage sludge. In this addn. the waste consists of spent porous carbon which has already been used as an absorption mass and is charged with various impurities; and redn. of the oxides pref. occurs at 750-1200 deg.C. The pref. waste consists of (a) active charcoal made from wood scrap, and spent by use in absorption processes; or (b) spent porous carbon initially obtd. by the coking of mineral- or brown-coals. The invention provides another inexpensive waste material which can be used as a replacement for coke in blast furnaces or in direct redn. methods of iron mfr.

Title: Collimator for parallel light beam from semiconductor diode laser - uses coiled glass fibre wave guide with transparent plastics outer skin
Inventor: SCHIFFNER GERHARD DR
IPC: G02B6/14
Filed: 1979-09-07
Abstract: A semiconductor diode laser (1) emits a beam of light (11) which, although bunched but not particularly sharp, passes through a converginglens (L1) placed in its path, the rays meeting at the focal point (f) which is also the end surface (S) of a monomode light wave conductor (2). This is formed by a core-sheath-glass fibre, having sufficient length, and an outer coat of transparent material of suitable refractive index. The light travels along this waveguide (2) which is wound in a coil, and emerges from the other end surface (S1) as a pencil of light having almost the quality of an ideal point light source. This pencil of light (12), then passes through another converging lens (L2). The rays emerging from it as an ideal parallel beam (13). This is an improvement over the usual opaque screen with a minute hole in it, since very little useful light is lost.

Inventor: GRUENSCHLOSS EBERHARD DIPL ING
IPC: B29C48/12
Filed: 1979-09-11
Abstract: Screw extruder, for thermoplastics or elastomers fed in as a powder, moves, consolidates, fuses, and homogenises the material. It has a solids zone coaxial with the other zones which provides the movement plus pressure build-up, a preplasticising zone to form more or less homogeneous melt, and a zone to homogenise mechanically and thermally. In the preplasticising zone the screw has at least one flow path open at each end. The lead angle psi of this flow path is 25-90 degrees and is defined by (I) where D is o.d. of the screw and s is pitch of the screw thread. Min. pressure at the end of the preplasticising zone, hence minimal wear on barrel and screw, minimal starting torque with a filled screw, minimal cooling required at feed end, max. preplasticising efficiency and therefore homogeneity, optimal geometry of screw in fusion zones are obtd.

Title: Multilayer protective coating for concrete and masonry - with plastic foil embedded in adhesive compound
Inventor: DEITERMANN WOLFGANG DIPL KFM
IPC: E04B1/66
Filed: 1979-10-26
Abstract: A multi-layer protective coating is applied to concrete walls, brickwork, flat roofs or other mineral surfaces by producing a self-hardening layer of a cold-working adhesive compound, in which a web of a thin foil is embedded. The foil is made of elastic material which retains water and which carries, at least on one side, a layer of textile material or of glass fibre mat; the latter is bonded or welded or joined to the foil by uniformly distributed, bonded or welded spots. This creates with a minimum of cost and labour an efficient sealing material for tunnels and foundations against ground water, in spite of cracks in the masonry.

Title: Pushbutton with pressure sensing element - has indirect pressure on element via leaf spring
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: H03K17/975
Filed: 1979-12-17
Abstract: The risk of damage to the pressure sensing element of pushbuttons due to excessive force is eliminated, as the pressure tp the element is transmitted indirectly via a multiple leaf spring. The rim of the rigid, dome shaped moving top (2,12) of the pushbutton rests on a multiple leaf spring (13) which, in turn, rests in a recess (15) of the case of the pushbutton assembly. Space (18) allows for deformation due to excessive pressure on the button (2). A lateral support (10,11,19) prevents excessive flexing of the element (1).

Title: Gastrointestinal tract treatment - by ferromagnetic tampon applied by strong magnetic field
Inventor: SMITH FREDERIC W
IPC: A61K33/26
Filed: 1980-01-24
Abstract: Prepn. for local treatment of gastro-intestinal tract, e.g. to staunch bleeding from ulcers, or to treat other infections and injuries, contains ferromagnetic particles which are applied by magnetic attraction. A tampon consiting of finely pulverised ferromagnetic particles, mixed with viscous liq., is introduced and directed under endoscopic inspection to the bleeding part. A strong magnetic field is then applied and the pressure exerted on the wound is usually sufficient to still the bleeding. This is a safer method than cauterising by a laser beam or using a tissue adhesive.

Title: Insulated electric cable mfg. - uses braided-netting structure of extruded high tenacity plastics
Inventor: WERWITZKE LOTHAR
IPC: H01B7/22
Filed: 1980-03-19
Abstract: The extruded insulating material for the metal strands, to give a high tension electric cable, is a high tenacity stretch material, formed into a braiding or netting type structure. The mean thickness of the material is 0.1-1.2mm, pref. 0.2-0.8mm, and a mean weight of 20-400 g/m2, pref. 40-100 g/m2. The braided/woven material can be bonded, and can be delivered in strip form and applied with overlapping edges.

The longitudinal or horizontal filaments cross each other at an angle of about 90 deg., using filaments of 100-1300 den, preferably 200-600 den. The mean free surface area in the braiding or netting for neighbouring extruded layers is 0.8-8.0 mm2, pref. 1.0-5.0 mm2. The process gives a high draw strength and a long operating life.
Patent DE-3014275-A1 (DE)
IPC: E04C5/12
Filed: 1980-04-15
Abstract: In order to secure the position of the wedges (12) of a wedge anchoring means for a tensioning member, the invention provides a pressure-applying plate (1) which is pushed onto the tensioning elements (11) of the tensioning member, until it rests on the end surfaces of the wedges (12), and can be fastened on the wedge anchoring means by means of screws (4). The screws (4) are fastened on the pressure-applying plate (1) in captive fashion between a threaded sleeve (19) and a perforated plate (26). A spring (22), which is located between the perforated plate (26) and the screw head (25), may, at the same time, be pre-tensioned by means of the threaded sleeve (19). Consequently, the screws (4), connected to the pressure-applying plate (1) in captive fashion, can be easily screwed onto corresponding fastening parts on the wedge anchoring means first of all by hand, while a tool only has to be brought into use for the remaining screwing-on and the activation of the spring force of the spring (22) which has already been pre-tensioned. <IMAGE>

Title: Pressure regulator for air compressors - has regulator located on compressor inlet and is controlled by output pressure
Inventor: DELFS JOACHIM ING GRAD
IPC: F04B49/02
Filed: 1980-07-30
Abstract: A pressure regulator for use with air compressors is located in the inlet time and eliminates the wasteful dumping of compressed air. The regulator (1) has an inlet (2) that is coupled over a regulating poppet valve (6,7) to the inlet of the compressor (5). The compressor outlet is supplied to a reservoir (22) and a branch time (21) connects with the control stage of the regulator.
