Title: Compost tank made from perforated galvanised sheets - joined at vertical edges by clamps and bent to cylinder
Inventor: HOERMANN MICHAEL DIPL ING
IPC: C05F17/02
Filed: 1975-12-15
Abstract: A compost tank is made from a number of upright, perforated, ribbed, galvanised steel sheets, the edges of adjacent sheets are coupled together by a vertical line of separate clamps and bent round to form a cylindrical wall. Each clamp is a flat plate, with two opposite lugs each formed through two successive 90 degrees bends to the shape of a hook. These hooks engage in the edge row of perforations of each plate. Pref., the centre of the plate has a hole formed by bending out a flat shelf to act as a spacer between the edges of the galvanised sheets. The top edge may be bent through a right angle to form a flange with a central hole. A vertical bar is passed down through all these holes of a line of clamps to hold them in place. The hooks pref. have chamfered edges facing one another. Standard galvanised sheets of the type used for ventilating doors in basements, garages, etc. can be employed for assembling a compost tank, by connecting them together by the clamps.
Patent DE-2600207-A1 (DE)
Title: Forming relief patterns on materials sensitive to radiation - by chemical reaction under action of electromagnetic or corpuscular radiation
Inventor: KOSTYSHIN MAXIM TIMOFEEVICH
IPC: G03C1/705
Filed: 1976-01-05
Abstract: Relief patterns on materials sensitive to electromagnetic and corpuscular radiation are produced by forming a metal layer on a substrate, followed by a layer of an inorganic material capable of chemically reacting with the metal layer with the formation of reaction products having different physical and chemical properties than the inorganic material and for metal. Image of a pattern is projected onto the coated surface and some parts of the coating and removed. This method is improved in that between the metal layer and the inorganic material layer on intermediate layer is introduced consisting of a material which is inert with respect to the metal and the inorganic material unless exposed to an electromagnetic or corpuscular radiation. The thickness of this intermediate layer is sufficient to prevent any reaction between the metal and the inorganic material in the absence of any activity radiation. After the projection of an image the unwanted parts of this intermediate layer are removed along with the unwanted parts of the other layers. The intermediate layer is pref. formed by contacting the metal surface with an atmos. contg. O2 and/or Fe, Cl2, Br2, I2, S, Se or Te. Alternatively, the intermediate layer can be formed by chemical deposition from a soln. or a melt. The removal of unwanted parts of the intermediate layer can be carried out mechanically or by chemical etching or by sublimation at an elevated temp. During the irradiation an electric field can be applied. Objects with a relief surface pattern can be produced, such as holograms, diffraction gratings, polarisers for electromagnetic waves, photo stencils, elements of microcircuits, printed circuit plates, information storage cells, typographic plates, etc. Electromagnetic or corpuscular radiation having a lower intensity than in the conventional process can be used; red and mean infrared light can be employed.

Title: Combined road and track passenger transport system - has transverse trapping and aligning elements with transverse setting sensors at road to track transition points
Inventor: FOERSTER STUTTGART PROF DR ING
IPC: B62D1/26
Filed: 1976-11-16
Abstract: The traffic system, esp. a public urban passenger transport system, uses road-travelling vehicles which can move on tracks, and track channels with lateral guide stems. At the point of transition (10) from a road area (2) to the track channel (3), and/or on the vehicles (1), elements are fitted to catch the vehicles in the transverse direction, and to align them at the start of the channel. These elements can incorporate transverse setting sensors and reference lines, to establish relative transverse setting and/or lengthways inclination between vehicle and channel start. This obviates the danger of an excessively fast approach, liable to lead to side collisions.

Patent DE-2714091-A1 (DE)
Title: On=off valve for fluids or bulk goods - has enclosing electromagnetic coil and valve piston with external spiral grooves
Inventor: BRAND PETER
IPC: F16K31/06
Filed: 1977-03-30
Abstract: The cylindrical on-off valve is enclosed by the windings of an electro magnetic coil. The valve housing has inlet and outlet ports at opposite axial ends. A cylindrical valve piston which has external helix grooves is moved axially due to the magnetic field generated by the coil. When the valve is closed, the valve piston is in contact with a seal face (17), thus no flow occurs. In the open valve position, the piston lifts off the valve seal face and the medium is able to flow through the helix piston grooves to the outlet port.

Title: Measurement system for consumed heat - determines temp. difference values of heating medium and applies them to summating counter which adds results
Inventor: CHABORSKI HOIKO DIPL ING
IPC: G01K17/16
Filed: 1977-08-16
Abstract: The system comprises a meter, and the flow and temperature difference are measured between the heating medium inlet and outlet. Measurement results are multiplied with each other, taking into account the temperature coefficient. Temperature is measured by a sensor consisting of a linearised thermistor network, whose resistance-temperature characteristic and reproducibility are highly accurate, as in 2710782. The temperature difference values are applied in digital form to a summating meter, which adds them until a certain digital value - the detection number Z - is reached, when the mechanical meter for the consumed heat is moved forwardly by one step.

Title: Motor vehicle key with noise generator - reminds driver of key position and is silenced in working position
Inventor: NISSL JOSEF
IPC: E05B45/06
Filed: 1977-09-10
Abstract: The key for a motor vehicle has a holder preventing locking out from the vehicle. The key holder produces a signal drawing attention to the key so that, e.g. the driver is not locked out. The key fob (7) has a humming noise generator (5) powered by a miniature battery (6). The switch for the noise generator is held in an enclosing glove (3). Alternatively, a reed switch can be used. The switch is disconnected if the key is not in an active position, e.g. if the vehicle is driven with the key in the ignition position. When engine is stopped an acoustic signal is produced.

Title: Separation of oil-water emulsions - using improved coagulating agents injected into mixing stream with compressed air followed by separator
Inventor: HEIDENREICH HANS
IPC: B01D17/04
Filed: 1977-12-09
Abstract: Dissolved, emulsified or suspended materials or an intimate mixt. of such materials in an aq. phase are separated by a process which has novel features both in mixing and in the coagulating agents used. It gives special results in chemical kinetics. The agents used can have a coagulating effect on emulsified or suspended phases or adsorb out genuinely dissolved phases. The reagents are made from an inorganic material of the base exchange ore type combined in various proportions with organic materials. Hydrophobic properties can be developed in some types. The mixing requires high shear, e.g. in a pin mill. Used for sepg. aq. mixts. of various components both dissolved and suspended e.g. cut oil emulsions. Gives improved mixing, low space requirement, energy saving, faster chemical reaction and lower reagent usage, high separation efficiency, and easy handling of the reagents by operators.
