Patent DE-2620462-A1 (DE)
Title: Reducing gas prodn. for metallurgical processes - from solid, liq. or gaseous agents having carbon content in presence of a molten metal bath
Inventor: PASCHEN PETER DR
IPC: C10J3/57
Filed: 1976-05-08
Abstract: Reducing gas for metallurgical processes is produced from solid, liq. or gaseous C carriers in a molten metal bath by converting them through an oxidising gasifying agent to a mixt. of CO and H2. In a first stage, the molten metal is carburised until it is satd. with C. In a second stage, the C in the metal is gasified by the oxidising gasifying agent and extracted as reactant gas. The result is a more flexible process of gasification. Both the specific gasifier output and the reducing gas yield are at a high level.

Title: Food industry wastes clarification esp. for olive oil prodn. - comprises two aeration stages with dilution by recycled activated sludge water
Inventor: ASENDORF ERICH DR
IPC: C02F3/34
Filed: 1976-09-07
Abstract: In a biological clarification system, the wastes from the food industry pass from a storage tank to a first activation stage where they are diluted at a rate of 1:50 to 1:400 with a water containing activated sludge. After intermittent aeration at a space loading of 1-8 kg BOD/m3.d another dilution at the same rate follows in a second activation stage. Sepn. from the activated sludge in a settling basin is followed by denitrification and final clarification. After aeration, a constant quantity of activated sludge is recycled. Used for clarification of effluents from prodn. of olive oil by pressing olive fruit. No make-up clean water is needed for the dilution and recycled water from the aeration tanks has proved very satisfactory. This system results in very highly loaded plants with excellent economy in operation. The BOD in the outgoing fluid is kept below 25 mg/l and COD under 150 mg/l.

Title: Roof gutter preserving and sealing cladding - comprises independent layer of flexible foil laid into gutter
Inventor: DIECKMANN ROLF
IPC: E04D13/064
Filed: 1976-09-25
Abstract: The cladding for roof guttering, esp. of zinc of plastic, is designed to preserve sealing qualities, esp. at section junctions, soldering or adhesion points, or other places subject to deterioration from weather, chemical or mechanical influences. For this purpose an independent cladding layer (2) is laid in the root gutter (1); it can be in the form of a flexible sheet of foil, resistant to these influences. The cladding can be adapted to the gutter shape and retained in position with spring clamps (3). It also imparts additional stability to the gutter. This preserves the guttering more permanently, and at less cost than painting or the application of trowelled substances, and saves the expense of replacing guttering, which sometimes involves also temporary removal of the bottom row of tiles.

Title: Electroconductive plastics layers prodn. - by mixing aq. plastics latex with aq. dispersion of conductive particles and drying film of the mixt. at above the m.pt. of the resin
Inventor: REUTER FRANZ GOTTFRIED DIPL CH
IPC: C09D5/24
Filed: 1976-10-09
Abstract: Process comprises (a) mixing an aq. plastics dispersion with an aq. dispersion of electrically conductive particles; (b) applying the mixt. in a thin layer to a substrate and (c) evaporating off the water at a temp. of at above the softening point of the plastic. Suitable plastics dispersions are e.g., (thermosetting) acrylic dispersions and polyisobutylene dispersions. The aq. dispersion of conductive particles may be e.g., of particulate noble metals or substances coated with noble metals, e.g., other metals, or carbon e.g., in the form of carbon black or graphite. Mixing of aq. dispersions of the components allows the prodn. of prods. contg. >=25wt.%, esp. 30-40wt.% carbon black etc., without using hazardous organic solvents. It is not possible to incorporate such large amts. of conductive particles by straight mixing of the components. The conductive particles form a coating on the plastics particles, so that the properties of the plastic material are not impaired. Prods. are useful for making conductive conveyor belts, stamped parts such as sealing rings, tans, etc.
Patent DE-2648908-A1 (DE)
Title: Therapeutic deep HF heating - involves cooling body surface over focus to counteract unwanted stray heating nearer surface
Inventor: SCHULZ HANSRICHARD DIPL PHYS D
IPC: A61F7/00
Filed: 1976-10-28
Abstract: HF or ultrasonic energy, generated at one fucus of a partial ellipsoid, is reflected towards a second focus at some little distance is in fact at a point lying somewhat shallower than the theoretical focus. If the focus lies too deep in the body, unwanted concentrations of energy appear between it and the body surface, affecting structures it is desired to pressure. To counteract this, the invention proposes that the hyperthermia be applied in conjunction with a coolant flow across the body surface. Cooling the body surface is pref. begun at a suitable time before the HF heating is started.
Patent DE-2648920-A1 (DE)
Title: Single crystal growth system - using float for crucible to keep constant level of growth front for improved homogeneity
Inventor: GILLESSEN KLAUS DR ING
IPC: C30B11/06
Filed: 1976-10-28
Abstract: A single semiconductor crystal can be grown from a melt of a first component in a crucible and from vapours of a second component from a reservoir below the crucible which diffuse into the crystal. A float, attached to the crucible, dips into a liquid with a low vapour pressure which is inert to the components of the binary compound and ensures that the crystal growth front remains always stationary. The stationary crystal growth front ensures that the crystal grows always at the same temp. The doping of impurities which is required, for example for light-emitting diodes, is now much more homogeneous, and crystals of greater length can be produced.

Alternative designs include a sloping groove through the needle, and the inserted suture has an enlarged end, which lodges in the groove. The suture may be secured by adhesive or cement, or a clamping ring may lock the end of the suture against the reduced end of the needle.
Patent DE-2711889-A1 (DE)
Title: Forming holes and channels in e.g. nuclear fuel element - using focussed laser pulses of high energy density to allow analysis of element
Inventor: OVERHOFF THEODOR DIPL PHYS
IPC: B23K26/12
Filed: 1977-03-18
Abstract: In the Parent Patent the formation of channels or holes in workpieces (a) using focussed laser pulses with energy density (ED) above the threshold of anomalous absorption (TAA) is described. In this addn., improvement is the use of single pulses with pulse rise time of 5-10 ns and half time of 50 ns, plus ED increased to 1011 W/cm2 at the point of impact and a TAA factor exceeding 10-100, with total energy of each pulse 10-5 to 10-3 joules. For highly reflecting pieces, e.g. SiC, a first pulse of very high intensity is pref. used to cause dissociation, the succeeding pulses having a lower TAA. An optical diode pref. shields the laser from reaction from the piece, whereas the pulse is kept short so vapour from piece does not dissipate the laser beam. The pref. appts. includes a vacuum chamber contg. a focusing lens and a holder with micrometer adjustment for piece. The evolved vapour can be analysed by a spectrometer. Small holes e.g. 10 mu m dia., can be produced with long length, e.g. over 200 mu m long, which are very accurate and reproducible. Used e.g. the analysis of fission prods. and contamination in or on nuclear fuel elements esp. coated particles; trace analyses; and drilling fine holes.

Patent DE-2712173-A1 (DE)
Inventor: FREY RENE
IPC: E05F15/47
Filed: 1977-03-19
Abstract: The electropneumatic safety control device having a pressure sensor (100) is designed for an automatic door or gate operating system whose drive can be controlled by the pressure sensor. Two pressure shaft switches (DW1, DW2) control two relays (d1, d2) of a controller (DWSR), which relays are connected in series with the system contactor (200), by means of the pressure sensor (100) during operation. In the event of defects in the pressure sensor or in the first relay (d1), the second relay (d2) takes over its function and automatically trips after a specific time so that the contactor (200), which is once again not live, allows the door to open; however in this case a defect indicator lamp (D11) illuminates. Admittedly the second relay (d2) can be pulled in again via a push button (30) and a defect contact arm (24), but the sequence of a tripping delay time has already started in a switching device (TZAB), after which the contactor (200) is finally switched off. The device can also be used in the case of a so-called latching contactor. <IMAGE>

Title: Box type solar collector panel contg. fibrous mat - which is esp. dark coloured to absorb radiation and conduct circulating liquid
Inventor: HADERER KLAUS
IPC: F24S10/55
Filed: 1977-04-30
Abstract: A solar collector for heating liquids comprises a closed, box-shaped container with single or double glass cover and with thermal insulation beneath. The entire interior of the container forms a part of the piping system through which the liquid circulates. Pref. the interior is entirely or partially filled with a substance which conducts liquid, pref. a fibrous mat. The fibrous mat. is pref. dark, esp. black to promote absorption of incident radiation. Metal powder or highly conducting material may be added to the fibrous mat. The casing is designed to cause condensation of liquid droplets on the underside of the glass pane; these act as small lenses, directing the radiation perpendicularly onto the fibrous mat so that there is not a great reduction in heat collected as a result on the sun's rays striking the pane obliquely. The heat storage capacity and the heat transfer surface of the fibrous mat are much larger and more effective than those of conventional absorbers.
