Title: Air duct filter for mine tunnels - with filter fitted with vibrators, air nozzles and dust discharge worm conveyor
Inventor: HOELTER HEINZ
IPC: B01D46/42
Filed: 1973-11-03
Abstract: The dust produced by the operation of a tunnelling machine or road header in an underground mine can be extracted and collected by drawing the dust laden air into a duct by a fan. The duct downstream of the fan is subdivided by a filter plate which is equipped with vibrators and/or air nozzles. The dust removed by them from the filter is discharged by a worm conveyor and the clean air is passed along into the next duct section. This eliminates the conventional wet filters which can cause trouble where the floor is inclined to swell. The clean air downstream need not be conveyed at high speed because the fear of dust deposn. has been obviated; the result is a considerable saving in power.

Title: Amplitude setting cct. for multi-standard PAL-SECAM TV - has two push-pull diodes across colour lines with junction periodically earthed
Inventor: BOSSE ROLF DIPL ING
IPC: H04N9/64
Filed: 1974-02-19
Abstract: The amplitude setting circuit, for multi-standard PAL/SECAM colour television receivers, adjusts the colour signal amplitude to accommodate the difference amplitude factors for PAL and SECAM systems. The SECAM system's colour difference signal are applied over resistors to two points whilst the PAL system is coupled via capacitors to these same points. The two points are connected by anti-series diodes whose common cathode-junction is connected via a variable resistor and transistor to earth. The transistor is controlled by a generator delivering a switching voltage of half the line frequency. Thus only a single adjusting means is necessary for both push-pull colour carriers.

Title: Sensitivity measurement of photocathode in insulating capsule - silica tube embedded in capsule as channel for removable test probe
Inventor: MCGEE JAMES DWYER PROF
IPC: H01J29/92
Filed: 1974-09-26
Abstract: The photocathode is set at one end of the insulating capsule which is made of silicone rubber and preferably coated externally with silica or perspex; the HT lead serving the photocathode is embedded in a channel which runs the length of the capsule. An electrode serves as a collecting electrode during tests of the sensitivity of the photocathode; it has no function in the normal working of the image tube, but, being near the cathode, it acquires a similarly high potential. This high potential is insulated by use of a contact which connects the test probe to the collecting electrode, situated at the bottom of a second channel, which also runs the length of the capsule and which is lined with a tube of silica or plastic. Between tests the probe is withdrawn, and its channel is plugged with insulating material.

Patent DE-2508010-A1 (DE)
Title: Stabilising system for laser beam alignment - has temperature-controlled raising and lowering device to compensate for drift due to temperature effects
Inventor: IMHOF ROBERT DR
IPC: H01S3/139
Filed: 1975-02-25
Abstract: The beam position is detected at a receiver matrix (8) at the far end of the optical system. The position detector gives an output proportional to displacement of the beam from its datum point (30) and a comparator-type control circuit (14) connected to the detector provides a variable voltage to a heating coil wound around a vertical aluminium tube (7) fixed to the rear support of the laser tube. A foot in the form of an Invar rod (27), passes through the centre of the aluminium tube and is fixed to its upper end. Increased heating current causes the tube to expand, lowering the rear of the frame and raising the laser beam. If the laser beam is too high, a reduced heating current allows the tube to shorten, raising the support end and lowering the beam to its required level. Vertical movement of the optical bench (1) is detected by a semi-reflecting mirror and second receiver element (35) placed midway along the bench.
