Patent DE-2521441-A1 (DE)
Title: Reinforced wheel rim for construction vehicle - with plastic moulded ring under rim edge all around periphery to provide balancing
Inventor: LUEDERS ALBRECHT DR ING
IPC: B60B21/02
Filed: 1975-05-12
Abstract: The deep profile wheel rim (1) of the construction vehicle has its outer edges reinforced by plastic rings (9, 10, 11) moulded to the undersides of the rim edges. The rings are even all the way round the rim to achieve a balanced wheel. This eliminates costly welds etc. used for conventional metal reinforcements while dirt and water have no collecting spaces in the smooth plastic outline. The main advantage of the plastic rings, apart from a simple and economic construction, is that stone damage to the wheel rims is minimised. This is especially useful in quarry work.
Patent DE-2525533-A1 (DE)
Title: Decoder for code with two or more valves - is used for ternary biphase level code without direct current and pulses are evaluated
Inventor: KISTER HORST
IPC: H04L25/49
Filed: 1975-06-07
Abstract: At least one of the states represents a level change within a time step interval; and each pulse generated by a level change within the time step interval is evaluated. An integration stage integrates each pulse appearing within a time step interval; it also controls means which generate a pulse when a given specified or higher integration value is present at the integrator output; further means form from each such pulse a signal with a level allocated to the respective pulse.

Title: ATOMATIC BRAKE SHOE SEPARATION ADJUSTMENT - uses spring biased strut limiting extent of retraction
Inventor: SCHMIDT HERBERT
IPC: F16D65/58
Filed: 1975-07-11
Abstract: The automatic adjusting device changes the length of the strut connecting the brake shoe of a hydraulic simplex brake and a second brake shoe connected to a hand brake lever. The strut is spring-biased towards either the hand brake lever and/or one of the brake shoes. The two shoes (1, 2) are fixed to the ends of rods (3, 4). The strut (5) limits the extent of brake shoe retraction during braking. The hand brake lever is attached to one of the rods (4) and rotation of the lever produces a movement apart of the brake shoes. A spring (7) keeps the strut (5) engaged with the lever (6) or rod (4).

Title: High temp. nuclear reactor hot gas duct shielding - prevents direct radiation shine to pod heat exchanger
Inventor: SCHMITT JUERGEN ING GRAD
IPC: G21C1/32
Filed: 1975-09-26
Abstract: Gas cooled nuclear reactor has heat exchangers mounted separately from the reactor vault, e.g. in surrounding pods in the vessel wall, hot gas leaving the reactor passes through a (radial) duct to the space below each heat exchanger. On leaving this radial duct the hot gas enters an annular space beneath the heat exchanger and separated from the central chamber beneath the heat exchanger by an inner annular wall possessing passages radially through it communicating between the annular chamber and central chamber. These openings are angularly offset from the point of entry of the hot gas radial duct into the annular chamber, so that there is no direct line of sight for the radiation from the reactor region to the space below the heat exchanger. The shielding arrangement shown ensures that no direct line of sight of radiation occurs along the hot gas duct to the heat exchanger pod, but at the same time it has a minimal effect upon the gas flow, excessive pressure drop is not produced and there is through mixing of the gas.

Title: Natural gas transport in arctic regions - by cooling compressed gas through absorption refrigerator using gas turbine exhaust
Inventor: GRUBER KURT DR ING
IPC: F17D1/02
Filed: 1976-04-14
Abstract: Natural gas is transported through arctic regions in pipelines at a pressure >50 bar by turbocompressors which are driven by gas turbines. The compressed natural gas is cooled to a temp. 0 degrees C (pref. -5 degrees C) by heat exchange with a coolant. The cooling temp. of the coolant is produced by absorption cooling based on the utilisation of the exhaust heat of the gas turbine. Method prevents the temp. at any point of the pipeline from # rising above freezing point which would melt the permafrost and lead to subsidence and pipeline fractures. The required energy is recovered from the waste heat of the gas turbines.

Title: Cable fault-finding equipment using pulse technique - has linear coupler and high speed sampler and digital processing system
Inventor: GALE PHILIP FRANKLIN
IPC: G01R31/11
Filed: 1976-09-30
Abstract: The cable fault finding equipment consists of a high-voltage DC generator connected via a resistor (14) to a capacitor (16). The high-voltage side of the capacitor can be connected via a switch and coaxial line to the inner conductor of the cable under test (11).

Title: Instrument for checking spinning nozzles - has ocular and projection microscopes aligned to nozzles holder on indexing table
Inventor: UHL WALTER
IPC: G01B9/04
Filed: 1976-12-22
Abstract: An instrument for checking spinning nozzles or similar details, has two interconnected microscopes. One is a projection microscope working with a beam of light passing through the object being examined, whilst the other is a monocular or binocular microscope working with either surface illumination or projected light. Parts of both microscopes are movable together in a guide between stops, so that in one end position the projection microscope comes into action, whilst in the other the eyepiece microscope can be used. Enables the checking of the nozzles for smoothness, cleanliness etc. and their rectification if necessary, to be effected much more quickly. When a point of light is missing on the screen, the table is indexed to bring the hole concerned to the point of intersection of the hairlines, and locked there. The hole can then be examined by the ocular microscope more closely.
