Title: Saw blade toothed milling cutter - has reversible cutting bits seated in pockets and fixed by wedge and screw assembly
Inventor: HEINLEIN HANS
IPC: B23D61/06
Filed: 1975-10-08

Title: Thin film RC modules - produced by monitoring RC product during capacitor dielectric application on meander resistor and final adjustment
Inventor: RENZ HANS-WERNER DIPL ING
IPC: H01L21/70
Filed: 1975-12-17
Abstract: Distributed RC-modules are produced by a thin-film technology for hybrid integrated circuits, used as filters or oscillators. The resistor tracks are applied from a valve metal in meander shape on a substrate. The capacitor dielectric is produced in a liquid electrolyte by an anodically produced oxide layer. The instantaneous value of the RC-product is checked during mfr. and oxidn. is stopped when it ies 10-20% below the desired final value. A capacitor electrode strip is applied, leaving the meander arcs uncovered, and the track resistance is raised to its final value by anodic oxidation or laser beam machining. The meander-shaped resistor tracks on the substrate are pref. produced by vapour deposition of a Ta or Ta/Al alloy with an addition of O2 or N2 to a thickness of 0.2-0.4 u. A simple thin-film structure can now be used for a distributed RC-module. High figures for the RC-product per unit area can be achieved by using a large part of the resistance material for the formation of the capacitor dielectric.

Title: Planetary gearing with tapered disc - describing circle cut by all flanks of coaxial discs' teeth upon conical shaped revolution
Inventor: FICKELSCHER KURT G
IPC: F16H1/32
Filed: 1975-11-24
Abstract: The planetary gearing has a revolving toothed tapered disc engaging at least two other toothed co-axial discs. The radial plane of the tapered disc enclosed an angle beta with the radial plane of the co-axial discs. The interfaces of the discs have outer teeth unequal in number. The teeth are on conical surfaces and are triangular or trapezoid in shaped. All the flanks of the co-axial discs' teeth cut points lying on a circle around the axis of the discs. One point of the tapered disc describes this circle upon a conical shaped revolution. All flank lines of the tapered disc's teeth cut this circle-describing point.

Title: Heat pump utilising waste heat of power station - also utilises waste heat from oil or gas driven IC engine
Inventor: HEIN KARL DIPL ING
IPC: F02G5/00
Filed: 1976-04-21
Abstract: A heat pump (2) is supplied with low grade heat from a district heating power station. (2). The input can be supplemented by heat (7) drawn from the atmos. or from river water or the soil.

Title: Carbonate deposit indicator for coffee making machine - has cold water level sensor cooperating with temp. sensor
Inventor: LANGER OTTO
IPC: A47J31/54
Filed: 1976-06-09
Abstract: The carbonate-deposit indicator indicates deposits of calcium carbonate etc. inside the water heating compartment of a coffee or tea making machine. A first sensor detects the presence of the water in the cold-water feed. A second sensor detects when the water in the heating compartment has reached the required temperature. A signal generator (16) produces an output signal when both sensors operate -- i.e. when cold water is present and the hot water is at the required temperature. The first sensor consists of a flexible membrane (3) or of a floating magnet. The second sensor is a thermostat. The arrangement prevents cold water remaining in the feed from causing deposit indication.

Title: Three dimensional garment sections of laminated textile fabrics - which have polymer constituent plasticised and moulded successively
Inventor: STURTZEL HORST
IPC: A41H43/00
Filed: 1976-07-07
Abstract: Garment sections, esp. of textile fabrics are given three dimensional form during the bonding of an outer fabric and an inlay. Two details consisting in part or wholly of polymer material and provided with an adhesive which can be melted, are heated uniformly whilst flat until they become plasticised, are then subjected to compression or suction so that they abruptly stretch and deform. The press. or vacuum is maintained until the details have cooled to a point below the consolidation temperature, and they are then ejected from the moulds. Heating and moulding may take place at two distinct work stations, close together, and be carried out in parallel. A quick method of producing three dimensional garment sections with a neglible degree of retrogression, and a contour which is completely wash and dry-clean proof. The formed sections can be stacked mechanically without difficulty and there is good adhesion and stability of the laminates.

Title: Low temp. carbonisation of fuel with high inert material content - with part of hot solid residue recycled to carbonisation zone to intensify heat transfer
Inventor: ROHRBACH RUDOLF
IPC: C10B49/16
Filed: 1976-12-09
Abstract: Fuels with a high content of inert material, e.g. oil shales are treated in a low-temp. carbonisation process by passing the fuel through a heat generator in which the organic components of the residues from the carbonisation process are burned. Novelty is that a side stream of the hot residue leaving the heat generator is recycled into the carbonisation zone. This greatly intensifiers the heat transfer to the material to be carbonised. The process is speeded up and a higher throughput is achieved.
Patent DE-2700472-A1 (DE)
Title: LV distribution pillar of circular cross section - has annular bus rings carrying fuses on outer faces over almost whole circumference
Inventor: WALKENHORST ERICH DIETER DIPL
IPC: H02B1/18
Filed: 1977-01-07
Abstract: The object of the construction is to save both space, and installation costs if subsequent to initial installation further cables have to be connected to the pillar. It comprises a central post (3) set in the ground. It carries a cable support ring (6) and the bus rings (4). On the radially outer edge of the bus rings are the fuse carriers (7) protecting each outgoing spur. The whole is covered by a cylindrical hood (1, 2) which can be adjusted, within limits, for height. The annular bus rings allow the mounting of fuse holders over practically the entire circumference, thus, if only partially filled during initial installation, further circuits can be added without having to extend the busbars. Also the use of bus rings allows smaller conductors to be employed in their mfr. as the current distribution is more favourable than on straight bars.

Title: Variable angle mixer blade on rotor shaft - is adjustable relative to supporting arm fixed to shaft
Inventor: OERTEL JOHANNES
IPC: B01F15/00
Filed: 1977-01-24
Abstract: A variable pitch mixer blade for a rotary mixer is adjustable in its pitch angle relative to its radial support arm; this support arm is, however, fixed relative to the shaft. Pref. the blade is attached to the arm by a bolt-and-nut connection passing through an elongated hole, pref. in the arm, and a circular hole, pref. in the blade. By loosening the nut, the blade can therefore be adjusted to different positions relative to the arm. For mixing any powdered, granular or plastics material where a wide range of problems can be encountered and the pitch angle must accordingly be adjustable. The arrangement enables the shaft to be of simple construction since the arm can be clamped around it. Moreover, the arm itself and the blade can be made as simple castings requiring no special machining to finish them.

Title: Outlet valve for pressure vessel for autoclave - can only be locked when valve is pressed onto seat
Inventor: MAUCH ROBERT DIPL ING
IPC: F16K35/02
Filed: 1977-03-15
Abstract: The outlet valve (1) for a pressure vessel or autoclave is closed by rotating the end cap (8) by means of the handle (9). The end cap (8) is attached to the sleeve (22) which is provided with a helical slot (21). The stub shaft (20) of the collar (19) of the bolt (17 fits in the helical slot (21) so that rotation of the sleeve (22) pushes the valve head (13) onto the seat (7). This roation of the end cap (8) also rotates the outer sleeve (6) and aligns the locking ball (36) with recesses in the threaded ring (41) so that the sleeve is firmly locked to the body of the outlet valve. The is thus locked only when the valve head (13) is on the seat (7).
