A plastics covering cap is used which has inserts for a wrench for handling of the marker fixed points are secured by insertion of a rod into the tube previously driven into the ground.
Patent DE-2428078-A1 (DE)
Title: Sprung wheel for high speed train - with wheel rim offset to produce small lateral force to prevent fluttering at speed
Inventor: THUM HELMUT ING GRAD
IPC: B60B17/00
Filed: 1974-06-11
Abstract: The running surface of the train wheel is provided by a separate wheel rim (1) which is braced on the wheel by two interlocking wedge shaped elastic pads (2). The pads are located between a sloping surface of the wheel and a wedge shaped securing ring clamped to the wheel using a retaining slip. The centre of action of the wedge shaped pads is offset from the centre of action of the wheel rim on the rail. This results in a slight torque on the wheel rim to produce some lateral force. This prevents the wheel rim from 'fluttering' at high speeds, and reduces wheel rim wear.

Title: Vertical calciner for heating Portland cement pellets - which then travel into a rotary sintering furnace
Inventor: GOTTLIEB STEVEN
IPC: F27B7/20
Filed: 1974-08-30
Abstract: Thermal treatment of pelletised material subjected to an endothermic reaction at a temp. lower than that involved in a subsequent sintering operation or chemical reaction, comprises feeding the pelletised material down through a vertical calciner in counter-current to exhaust gas leaving a relatively short rotary roasting furnace, and feeding additional heat downwards through the vertical calciner for complete calcination without sintering, so the raw material is still in a pelletised form when it enters the roasting furnace for sintering or for another chemical reaction. The process is pref. applied to the calcining of Portland cement. Provides reduced plant- and maintenance- costs due to the smaller size of the equipment employed, and reduced heat-consumption.

Patent DE-2517933-A1 (DE)
Title: Test system measuring characteristics or FM radio comm. equip. - operates at both seventy and one hundred and forty mhz and uses transmitter and oscilloscope
Inventor: MUELLER MARTIN DR ING
IPC: H04B17/10
Filed: 1975-04-23
Abstract: The test system, for measuring the characteristics of FM radio communications equipment, consists of a transmitter feeding the equipment under test. The output of the test object is passed to a receiver whose frequency demodulator demodulates the FM test signal and displays the results on e.g. an oscilloscope. The demodulator input passes over two mixers to a frequency/voltage converter that drives the display. Two switches allow the two mixers to be bypassed and the input signal to pass via a frequency doubler to the same converter. The advantage of this switching lies in its allowing both 70MHz and 240MHz IF signals to be accommodated.

Title: Automatic object cross-sectional dimension measurement - using reflected optical interference patterns scanned by readout unit
Inventor: SCHULZ WOLFGANG DR ING
IPC: G01B11/24
Filed: 1975-08-18
Abstract: The equipment is for measuring the external cross sectional dimensions of a sutable object, typically a pipe, wire or strip of material, by means of scanning an optical interference pattern reflected from the object. It consists of a laser source (1) which sends a light beam into interferometer (4) through a beam, expansion telescope (2), and a set of prisms and mirros (5, 6) which direct the resulting interference pattern on to both sides of the object (8). The pattern reflected from this is scanned by a revolving mirror (9), lens (10) and photodetector (12), or alternatively by a television camera, resulting in a time signal which is periodic for a length of time dependent on the cross sectional dimension of the object (8) being examined. An accurate measurement of that dimension can be made by axamination of this signal.
