Title: Mine double roller cutter height control - uses differential amplifier and current transformers signalling excessive rear roller loading
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: E21C35/04
Filed: 1978-12-16
Abstract: The tachogenerator coupled to the winch drive motor, on the double-roller cutting machine used in underground mineworking, is connected to a differential amplifier. This, in turn, is connected to current transformers in the supply feeds for both cutter motors. When a set value is exceeded, the transformer's signal proportion to the last roller's loading, releases a differential amplifier signal to act on the setting cylinder controlling this roller's height, as well as on the winch control. It raises the roller from the seam floors, and reverses the winch's running direction. On shortfall in loading, the roller is lowered again and the winch again reversed. This provides protection against excessive loading on the rear-travelling roller.

Patent DE-3002336-A1 (DE)
Inventor: WALTER HANS ING
IPC: B05D1/24
Filed: 1980-01-23
Abstract: For the identification of metallic articles, such as pipes, while simultaneously ensuring effective corrosion protection, a two-layer coating is proposed, in a first process step a first thermoplastic coating being applied onto the metallic articles, the stabilisation of the layer thickness provided by which coating ensures the desired corrosion protection. This first layer is moreover coloured black, by means of which the stability of the coating can be improved. The second coating, representing the colour-identification layer or the colour marking, can be coloured in any manner, no consideration needing to be made regarding the possible decomposition of the colourants in light, since this layer no longer contributes to the corrosion protection. Furthermore, the layer thickness of the second layer can be chosen just sufficiently thin for the desired colour impression to result.

Title: De-synchronisation determination for a synchronous machine - uses functional value of base and harmonic components airgap flux and allows network disconnection
Inventor: UENOSONO CHIKASA
IPC: G01R31/34
Filed: 1980-02-26
Abstract: The desynchronisation determin. system for a synchronous electrical machine uses the functional value of the magnetic air-gap flux. The latter incorporates a functional value for the base oscillation component and a functional value for the higher harmonic components. Desynchronisation is indicated when the ratio of the base component value to each of the harmonic component values drops below a given reference value. The desynchronisation is indicated by detecting a drop in the absolute value of the longitudinal flux as well as the transverse flux. The system is applicable to a synchronous motor, a phase-shifter or a synchronous generator and allows a machine going into desynchronisation to be detected before it can effect the whole network.

Title: Gas filter bags cleaned while still in casing - by external liquid sprays in upper zone and internal gas pressure pulses
IPC: B01D46/00
Filed: 1980-06-13
Abstract: The Parent patent describes a method of cleaning gas filter inserts (filter bags) by removing them from the filter casing and spraying them externally with filter jets, while applying gas pressure pulses to the inside. In the patent of addition, the method is carried out with the filter bags still mounted inside the filter casing, where a top plate divides the clean and dirt gas chambers. Pref. in the upper third (or upper quarter) of the dirty or dusty gas chamber, nozzle pipes are equipped with upwardly oriented and downwardly oriented nozzles, so arranged that the upward jets clean the underside of the top plate and the attachment portion of the bags, while the lower jets sweep the upper third of the filter bags. Used in particular for air filtering or gas filtering where the gas contains dyes and pigments of different colours and it is sometimes necessary to remove dust from one process before a different process is used, to prevent contamination by dye of a different colour. With the new arrangement, firstly it is not necessary to remove the filter bags from the filter casing, while secondly it is found that by spraying liquid only onto the upper third or quarter of the filter bags, the pulsating gas pressure inside the bags is sufficient to dislodge the dust from the entire remaining length of the filter bags right to the bottom.
