Title: Shaped-mould underground air shaft - with alternately convex and concave corrugations in horizontal section narrowing outwards
Inventor: HERING PETER
IPC: E04F17/06
Filed: 1974-03-08
Abstract: For max. stability the air shaft must be of approx. semicircular shape in the horizontal section, it consists of a doubly arched shaped mould unit which is open to the top and towards the wall of the building. It is given an undulating shape in horizontal section, with corrugations reducing in radius from the edges fitting against the wall outwards, down to a predetermined min. level. Viewed from outside, the curves are alternately convex and concave, the concave ones having a smaller radius of curvature than the convex. The edges fitting against the wall are pref. formed by the arches of half convex corrugations abutting vertically against the wall. This can be made in varying sizes on the same principle, and used in conjunction with large-area windows, and has great load bearing capacity in proportion to weight.

Title: Test caliper for ferromagnetic test pieces - has core made up of ferromagnetic sheets stacked upon one another
Inventor: FOERSTER FRIEDRICH DR PHIL
IPC: G01N27/90
Filed: 1974-06-29
Abstract: The core of the test caliper is composed of ferromagnetic sheets stacked on top of one another and is adapted to the surface shape of the test pieces. At least one winding is coupled to the core, so that changes in a magnetic alternating flux in the core, caused by applying the test caliper to a test piece, are decoded by a test unit connected to the winding in the form of a criterion of the properties of the material. The core is adapted to the surface shape of a test piece by repeated shifting of the sheets towards one another. The sheets are supported to slide in a guide mechanism to which the winding (5, 6, 7) is fastened.

Title: Cathode ray tube heater prodn. - using collodium in insulating and (iso)-butanol in dark coating compsn., eliminating presintering stage
Inventor: MERK HANS
IPC: H01J9/08
Filed: 1974-08-09
Abstract: In the prodn. of a cathode ray tube heating element with a dark coating, the element is first given a light-coloured insulating coating; the dark coating is applied to the unsintered insulating coating and then sintering is carried out. The insulating coating is applied using collodium as the binder and the dark coating using BuOH, esp. iso-BuOH as solvent. Coatings with good insulating and adhesive strength can be produced, with good reproducibility, without carrying out several sintering processes, since BuOH and iso-BuOH attack the collodium-contg. coating only well enough to give good adhesion, without dissolving the coating or causing mixing of the layers.
Patent DE-2439669-A1 (DE)
Title: Butt weld for flat plates - grinding wheel cuts groove along rear of initial weld
Inventor: CRAWLEY STANLEY
IPC: B24B19/02
Filed: 1974-08-19
Abstract: A groove is cut along the back side of a butt held seam between two melting metal plates using a grinding disc which can be pivoted about a swivel pin and be moved along its axis of rotation. Mechanisms press the grinding disc against the weld seam so that while moving along the weld seam, the grinding disc grinds a groove (22) of regular cross section. The disc and the drive motor are arranged on a holder mounted on a slide carried by an arm, which has a slide guide and can pivot about the swivel pins. A support roller is tilted to a further lever arm which is pivoted to adjust the spacing between the grinding disc axis and the parallel support roller axis relative to the first arm.
Patent DE-2453264-A1 (DE)
Title: Automatic control for car heater - with feedback control using cold and heated air from both sides of heat exchanger
Inventor: BREITSCHWERDT WERNER DIPL ING
IPC: B60H1/00
Filed: 1974-11-09
Abstract: Air is taken from the warm air inlet duct of the heating system, using two special pipes which direct their airflow onto a bimetallic strip controlled valve. This regulates the engine vacuum servo control of the warm water valve on the heat exchanger, with a feedback control to the vacuum servo which operates a control flap to move from one special pipe to the other. This controls the amount of heating of the bimetallic strip and ensures a constant heat input to the car, irrespective of car speed and outside temperature.

One end of each spring n18) is fixed to the plate (10) and the other end of the spring (18) has magnetic means cooperating with magnetic means secured to the plate (10) to provide a reciprocal attraction between them. A contact (26) is provided at the free end of each spring (18) which comes into contact with a second contact (28) underlying it, when the spring is deflected (18) away from the plate (10), by a depression of a push button (14) located in the corresponding aperture (12).
Patent DE-2455597-A1 (DE)
Title: Analogue angle or stroke measuring equipment - uses photoresistors connected to form differential sensor used with moving shutter
Inventor: MERK HANS-DIETER
IPC: G01D5/34
Filed: 1974-11-23
Abstract: The motion to be measured is translated into a difference in light intensity caused by movement of a shutter in front of a light source. The shutter may be arranged so that as one photoresistor receives more light the other photoresistor receives less light, and it may be of a spiral shape. A weak spiral spring connected to the moving object may translate its movement into changes in force produced by the spring, and this force controls the position of a shaft bearing the shutter. The shutter is supported on a strong or hard spring so that it makes small movements in response to changes in applied force.

Patent DE-2500699-A1 (DE)
Title: Automatic control method for automatic reaction plants - is for plants such as detoxication plants for liquids or neutralisation plants
IPC: G05D21/02
Filed: 1975-01-09
Abstract: Contaminants present in water used in the plant are monitored by substance and/or ion selective pickups. Before the liquids are drained or pumped from a reaction tank, a test rinsing is made of the final pickup, and the rinsing fluid is analysed so that the apparatus tests itself for correctness of its calibration. The interlocking of permissible limits is such that pumping off or draining of liquids outside which are contaminated permissible limits is prevented; when a pickup is incorrectly calibrated or fails, delivery of the liquid is immediately stopped, so that contaminated liquid is not allowed to escape.

Title: Reducing dust concn. in mine air - during mechanical coal mining, by emplying hygroscopic pastes on tunnel surfaces
Inventor: LEWER HANS
IPC: E21F5/16
Filed: 1975-03-01
Abstract: Process for impeding dust formation in coal mines where the extn. of coal is undertaken using curbs and shields to support the surfaces of the tunnels, together with the hygroscopic salt pastes. The exposed roof layers in the tunnels are coated with a layer 1-10mm. thick of a conventional dust-binding paste directly before pressing the shields into position. The paste pref. contains calcium chloride and/or magnesium chloride, and a possesses a partial pressure due to water vapour below that in the air in the tunnel, and the penetration value of the paste is pref. 280-340 (when measured to DIN 51804). The paste pref. consists of a gel of Mg(OH)2 contg. 30-40% of the hygroscopic salts; the paste is pressed into the tunnel surfaces by the shield or prop and prevents the rubbing off of loose particles.

Title: Working memory arrangement for several different processes - employed in data processing installation of time sharing operational type
Inventor: TRUMPP GERHARD
IPC: G06F12/06
Filed: 1975-06-04
Abstract: The working memory arrangement is designed for the processing of several different procedures in a time- sharing operational type date processing installation. The latter is envisaged as containing a main memory of large storage capacity. This main memory, in turn, contains several modules which can be connected to a central processor of the data processing installation via a module selection unit.

Title: Energy producing system using sulphuric acid - involves heat of soln. in water and use of solar energy to reconcentrate diluted acid
Inventor: ALADAG ILHAN DIPL ING CHEM
IPC: F24V30/00
Filed: 1975-07-01
Abstract: Concn. H2SO4 is diluted with water and the heat produced, when the components are mixed, created kinetic energy due to the explosive-like forces developed which is used e.g. to make electricity. Subsequently the diluted H2SO4 produced is then reconverted back into the converted form of the acid by virtue of the fact that the diluted acid has the ability to utilise the energy of solar radiation. The system allows fossil fuels to be used as sources of raw materials for the chemical and pharmaceutical inds. etc. rather than being burnt as a source of energy.
