Title: Measuring gas partial pressure - by gas electrode and alternate circulation of calibrating and test gases
Inventor: SCHRADER UWE DIPL PHYS DR
IPC: G01N27/49
Filed: 1976-03-03
Abstract: A selective polarographic electrode is used, and at spaced out points in time, a reference gas is used for post-calibration. For the measurement of the oxygen partial pressure in a gas, a polarographic oxygen electrode is used. The gas to be analysed is the spent gas of fermenter, and the reference gas is drawn from the air feed. The gas consumption of an installation can thus be measured. The method is simple to operate and an inspection is required only after 24 hrs working.

Title: Exhaust gas scrubbing - using irrigated moving bed scrubber with counterflow contact and bed recycle
Inventor: FOX FRANZ WINAND ING GRAD
IPC: B01D46/34
Filed: 1976-06-22
Abstract: Exhaust gas prufin. involves passing the gas through a bed of granules which are continuously recycled and through which water is passed in counterflow to the gas. A granule washing facility is provided in the recycle and in the water circuit, a purification facility is provided. This also includes a heat exchanger. The granules are recycled by means of a mechanical conveyor. The contracting is done inside a pipe to which the granules and water are introduced at the top and the gas at the bottom. This pipe has a zig-zag profile. Used for removing contaminants from exhaust gases before they ar discharged to the atmos. The principle of fixed bed filters is known. However the efficiency of these is greatest when they are clean. The system described ensures that the bed is always relatively clean by recycling it and a consistent cleaning efficiency is therefore achieved.

Title: Micrometer sliding gauge - has tapered calliper arm to provide micrometer scale for measurement of workpiece
Inventor: NABE HERMANN ING GRAD
IPC: G01B3/20
Filed: 1977-02-01
Abstract: A 'microgauge' for measuring to a precision of 1/1000 mm has a right-angled stock bearing a millimeter scale. Slidably mounted on this measuring stock are two right-angled arms. A workpiece to be measured is placed between the measuring stock and the first sliding arm. The edge of the arm remote from the workpiece is not normal to the measuring stock, but slopes at a gradient of 1/100. A measuring probe which is inserted in the slot between the two sliding arms also has an edge which slopes at a gradient of 1/100, this edge being in sliding contact with the sloping edge of the upper sliding arm. A millimeter scale on the measuring probe permits interpolations of the main scale to be read off.

Prods. have good mechanical strength and show attractive, pronounced marble effect whose effectiveness is pre-determined by control of the viscosity ratios as indicated above.
Patent DE-2719248-A1 (DE)
Title: Frequency selective receiver for telephone systems - has received frequencies measured by counting and allocated to frequency channels
Inventor: ROTHER KLAUS-DIETER DIPL ING
IPC: H04Q1/457
Filed: 1977-04-29
Abstract: The receiver (1) has limiters at its input, and received signals consist of several simultaneously appearing individual frequencies, each allocated to a certain group. Rectangular voltages derived from the individual frequencies are applied to detectors which measure by a counter each individual frequency. The counters are controlled by clock frequencies much higher than the frequencies to be measured. At first a small number of periods of rectangular voltages are checked by wideband monitoring for their belonging to the respective frequency group. After this the respective channels are determined by the counters, and the counters carry on counting during a number of periods individually allocated to each channel. Monitoring of half-periods in each frequency channel is narrow-band.
Patent DE-2719281-A1 (DE)
Title: Ultrasonic remote control receiver e.g. for TV - with pair of outputs providing variable duty cycle pulse train, one out increasing and other decreasing duty cycle
IPC: G08C19/12
Filed: 1977-04-29
Abstract: Reference frequency pulses are counted during a counting cycle comprising a predetermined number of received command signals, each command signal occupying a different frequency channel. At the end of each counting cycle, the reference frequency count is compared with the count during the preceding counting cycle. A validated output from the receiver occurs only after a predetermined number of uninterrupted identical comparisons have occured. Interference with a validated output signal by spurious received signals e.g. noise signals is minimized by providing for invalidation of an output signal only after a predetermined number of uninterrupted non-identical count comparisons. Two of the receiver outputs are used to generate a variable duty cycle pulse train, one output increasing and the other decreasing the duty cycle.
Patent DE-2720249-A1 (DE)
Title: Fixing for hard metal cutting insert - has L=shaped clamp with oblique recess for transverse pin to act as wedge
Inventor: GUGLIELMETTI PIETRO
IPC: B23B27/16
Filed: 1977-05-05
Abstract: The method of retaining the hard metal insert which forms the cutting edge of a turning tool uses an L shaped clamp. One arm of the L lies over the insert whilst the other arm is a sliding fit in a hole in the tool perpendicular to the surface of the insert. A pin fittin in a transverse hole projects radially into the hole which house the one arm of the L shaped clamp. This transverse pin engages an oblique surface formed on the side of the arm of the clamp. A screw forces the transverse pin into the hole so that it acts as a wedge and pulls the arm of the clamp into the hole and consequently tightens the grip of the clamp on the metal insert.

Title: Desk or table top fan - has slots in blades to increase air vol. delivered without increase of speed
Inventor: PLETTNER HEINFRIED
IPC: F04D29/38
Filed: 1977-06-29
Abstract: The desk or table top fan has an impeller with radial blades on a hub which is mounted directly on the shaft. There is a slot in each blade. The effect of the slot is to break up the air and thus increase the volume delivered by the fan to increase the cooling effect at periods of very high temperature. This avoids the expense of a special motor to operate the fan at high speed. The slot is preferably parallel to the axis of the blade but may also be perpendicular or inclined to the axis of the blade.

Title: Rear view mirror esp. for cycling, skiing, roller-stating etc. - is fastened to safety helmet on wearer's head and stuck to wind shield
Inventor: GELHARD EGON
IPC: A42B3/04
Filed: 1977-07-07
Abstract: The rear-view mirror is positioned in the region of a transparent wind shield (1) which lies in the wearer's angle of view. The mirror area (3, 4, 5) is applied as an adhesive film onto the outside of the transparent wind shield. This mirror area may be applied by galvanic means or by evaporation. The mirror area applied to the wind shield does not have a sharp-edged limitation and the degree of reflection increases continuously from the edge of the mirror area towards the centre or from bottom to top. Due to partial mirror-coating in the mirror area both the image lying before the observer and the rear-view image may be visible, being projected above one another.

Title: Optical barrier drive system - has LEDs and phototransistors sequentially powered and monitored to reduce power requirements
Inventor: FINKMANN HELMUT ING GRAD
IPC: G01V8/20
Filed: 1977-08-25
Abstract: The optical detector drive system comprises a click generator (1) and counter (3) whose capacity corresponds to the number of pulsed diode emitters (6). Each diode is activated in turn as the counter steps on. The receiver section consists of a number of parallel-connected photo-transistors controlled from a constant-current source (9). The output is connected to a threshold detector or Schmitt trigger (13). This in turn drives edge-triggered bistable circuits (14). The two outputs of the bistables are activated according to whether the transistor is activated or not. Further bistables (20, 21) monitor the photo-transistors and in the event of a fault, a light diode (22) is activated. The system lends itself to integrated circuit type of construction. Power supply demands are low.
