Filed: 1975-09-25
Abstract: A longwall conveyor composed of channel sections arranged end-to-end and a scraper-chain assembly moved to transfer material along the channel sections has a main drive station at one end and an auxiliary drive station at the other end. Each drive station has a frame rotatably supporting a drum around which is entrained the scraper-chain assembly. Drive motor and gearing units are carried by the frames and drive the drums. At each drive station there is a housing in which a sprocket wheel drivably engages with a chain used to haul a plough or a similar machine along the conveyor. Drive motor and gearing units are supported by the housings and drive the sprocket wheels. The housing and sprocket wheel at the main drive station is slidably mounted on the frame and a piston and cylinder unit effects slidable displacement of the housing to vary the tension in the drive chain. The frame at the auxiliary drive station is also slidably mounted to a structure rigidly connected to the conveyor channel sections and supporting or forming the housing thereat. Piston and cylinder units effect slidable displacement of the frame to independently vary the tension in the scraper-chain assembly.

Patent ES-458251-A1 (ES)
Title: Vertical deflection circuit
IPC: H04N3/16
Filed: 1977-04-28
Abstract: A push-pull amplifier, which is supplied with a first voltage, provides deflection current to a vertical deflection winding during a trace period of each deflection cycle.

Patent ES-8100976-A1 (ES)
Title: Pivotal and slidable auto roof cover
IPC: H02K23/66
Filed: 1980-04-11
Abstract: An apparatus for actuating a slidable and pivotally movable cover for use with an automobile roof opening comprises a control element, e.g. a disc, driven by an electric motor. A plurality of switch cones are preferably secured at equal radial distances from the rotational axis of the control disc. An actuating plunger is radially displaceable by each cam to move a biased actuating element which then operates a switching member of a control switch. This switches off the motor when specific portions of the cover are reached. In a first position of the actuating element, in which it is held against its bias by energized electromagnetic means, the actuating element is operable to displace the switch pin to switch off the motor. In a biased second position of the actuating element, with the electromagnetic means de-energized in consequence of the motor being switched off, the actuating element holds the switching member in its displaced position until the energizing circuit is again energized.

Patent ES-8203968-A1 (ES)
Title: Free Flowing Crystalline High Dextrose Bearing Product
IPC: C13B30/02
Filed: 1981-06-02
Abstract: A free flowing, handleable, crystalline, anhydrous high dextrose bearing product is prepared from a starch hydrolyzate. The starch hydrolyzate is first concentrated to a high dry substance level. It is then simultaneously crystallized and crushed by mixing while cooling. Seed material selected from any crystalline sugar, e.g. dextrose, may be added during this stage. The crushed crystalline product is then further cooled and milled to a reduced particle size. Screening can be used if necessary to obtain a specific particle size. The crushed and milled product is then conditioned in two stages. The first stage is drying in a fluidized bed to less than about 0.5% total moisture and the second stage is cooling to below about 35 DEG C. Handleability (non-caking qualities) and composition stability with respect to crystallinity and beta-anhydrous dextrose content of the high dextrose bearing product are excellent even after it has been stored in bags for long periods of time.

Title: Daisy wheel printer.
IPC: B41J1/30
Filed: 1981-07-07
Abstract: A daisy wheel printer having a daisy wheel (10) with a central disc portion (12) and character stalks (14), wherein a masking disc (20) is attached coaxially to the daisy wheel, the mask being larger than the central disc portion of the wheel so that it obscures the daisy wheel stalks in a radial zone of the wheel inwardly of the character petals (16). The mask (20) is provided with a single slit (26) over the interstice between a unique pair of character stalks (14A, 14B), to thereby define a unique datum or home location on the daisy wheel. This datum slit is detected by means of a light source (28) and light-sensitive detector (30) which emits a pulse each time the datum slit passes through a light beam directed towards the detector at the radial zone of the daisy wheel whereat the datum slit is provided. The invention provides a datum slit enabling optical detection of a datum location on the daisy wheel without in any way affecting the performance of the daisy wheel for printing and, in particular, without affecting the flexibility of the character stalks.
