Title: Measurement of oxygen dissolved in water - is applied to plant with high corrosion risk and uses electrolytic detector
Inventor: HEIMKE GUENTHER DIPL PHYS DR
IPC: G01N27/26
Filed: 1973-12-21

The reflector is also for aircraft landing lights on aerodromes, and can be combined with a polarising filter on the aircraft windscreen.
Patent DE-2426859-A1 (DE)
Title: Measuring circuit for determining capacitances and resistances - is operation by compensating measuring bridges balanced by hand
Inventor: KLEIN HANS
IPC: G01R27/08
Filed: 1974-06-04
Abstract: After the switch (9) has been opened, the capacitance (Cx) discharges through the resistor (R). The discharge current flows through an impedance converter (1) and then flows to two comparators (2a) and (2b) connected in parallel. These comparators produce a time signal propositional to the capacitance. A switching arrangement for the measuring circuit ensures that a balancing of parasitic input capacitances is achieved by the adjustable pulse delay circuit (3). In an alternative version of the measuring circuit, the discharge of definite capacitances (C) with unknown resistances (Rx) can be used to measure the value of the resistances. The counter (7) receives signals from a control device (8) connected to the relay coil of the switch (9). The counter is connected to gates (5) and (4).

The extensions are separated by an annular groove (6) the bottom of which is close to the free or seal face (5) of the flange. Pref. the axial length of the inner extension, as measured from the seal face, is less than that of the outer extension (4) to facilitate access during welding. The inner face of the outer extension may be convergent towards the bottom of the groove and the confronting face of the inner extension may be divergent.

Title: Pipe bend with thermoplast lining made from tube - heated then blown to fit inside pipe
Inventor: PATZNER ALFRED
IPC: B29C49/26
Filed: 1974-10-03
Abstract: A curved length of pipe is internally lined with thermoplastics fitting closely to the inner wall. In a pref. prodn. method a thermoplastics tube is heated to its optimal deformation temp., inserted into a flanged pipe bend and then inflated to fit closely to the inside of the pipe; the projecting ends of the tube are then folded out to fit over the flanges. The lining and pipe may be bonded together with adhesive. Method is useful to produce a lined bend to be used in conjunction with straight lengths of pipe having thermoplastics linings. The process eliminates the need to use rubber-lined pipe bends for this purpose.

Title: Transfer function shaping circuit for narrow band TV channel - produces spheroid function increased in upper band to increase detail sharpness
Inventor: SCHROEDER HARTMUT DIPL ING
IPC: H04N7/12
Filed: 1974-12-13
Abstract: The transfer function shaping circuit for narrow band television channel modifies the transfer function of the channel pulse response, including its equalisation so that it approximates to a spheroid function. The modification is dependent on noise level such that the transfer function is increased in the region of the upper band limit. The video signal (VS) and a test signal (TS) from a test generator (2) are fed to an adder (1), coupled to a transmission channel (3). The latter output is coupled to a transverse filter (4), its control circuit (5) and a test signal retrieving circuit (6). The video signal is tapped at the filter output (7), in which is connected the input of a rated-actual value comparator (8).

Title: Video disc read device - has polarisation analyser for preventing reflected read beam reaching laser
Inventor: WINSLOW JOHN SEYMOUR
IPC: G11B7/24
Filed: 1974-01-24
Abstract: The video disc read device prevents the read laser beam's being returned to the read laser and consists of a polarisation analyser and a quarter-wave plate. The analyser is located between the read laser and the quarter-wave plate. The beam from the read laser passes in both directions (incident on and reflected from the video disc) through the quarter-wave plate. The quarter-wave plate and analyser therefore prevent the reflected beam from returning to the laser. The analyser reflects part of the reflected read beam to a detector/monitor.

Title: Direct speed measurement of objects esp. vehicles - uses electromagnetic field disturbance as detected by two sensors
Inventor: OENEL BUELENT
IPC: G01P3/66
Filed: 1975-08-23
Abstract: A method and device for the measurement of speeds of objects moving in a straight line, e.g. road traffice, using detection of disturbances caused by the object in an electromagnetic field is designed for direct display of the speed without further processing. The method may be used with any shape of object without the need to know a partic characteristic dimension. Two sensors are placed a fixed distance apart along the object's path of motion. Each produces an output signal as the object, e.g. the front of a car, passes. The first signal triggers a pulse train of constant repetition rate which is stopped by the second signal. The number of pulses generated is electronically recorded and processed into a value for the speed which is then displayed.
