Patent ES-429600-A1 (ES)
Title: Apparatus for fractionating fiber suspensions in accordance with fiber length
IPC: B01D29/17
Filed: 1974-08-28
Abstract: A slurry of mixed paper making fibers of a wide range of lengths is fractionated into two fractions wherein the fibers are predominantly of lengths greater or less, respectively, than a predetermined intermediate control length, by feeding the slurry under pressure into the inlet end of a cylindrical screen member having slotted perforations of predetermined size and spacing in accordance with the control fiber length for the slurry to be fractionated, i.e. the slots are substantially less wide than the control fiber length and they are spaced to provide lands therebetween which are also less wide than the control fiber length. The supply flow is caused to circulate circumferentially of the wall of the screen member so that small fibers and other particles will pass through the slots to form the short fiber fraction, but fibers longer than the control fiber length will either flow past the slots or will fold over or "hair-pin" on the lands between slots. Periodic pulsations through the slots dislodge hair-pinned fibers for return to the supply flow and ultimate discharge from the exit end of the screen member to form the long fiber fraction.

Title: Method for removing sodium sulfate from aqueous solutions
IPC: B01D53/50
Filed: 1975-02-19
Abstract: Metal, e.g. sodium sulfate, is separated from metal, e.g. sodium sulfite, in a solution, for instance a solution used in a system involving contact of sulfur dioxide-containing gases with the sodium sulfite solution as an absorbing solution to recover sulfur dioxide wherein the absorbing solution is regenerated after contact with the gas and recycled for further use. A portion of the absorbing solution is purged to avoid the unduly large build-up of sodium sulfate in it. The purge stream is contacted with sulfur dioxide to reduce the amount of sodium sulfite therein to relatively soluble sodium bisulfite, and the relatively insoluble sodium sulfate is recovered therefrom as undissolved solids. The liquid separated from the sodium sulfate, which is rich in sodium bisulfite, is returned to the absorbing solution. In a preferred aspect, the purge stream is withdrawn from the absorbing solution subsequent to contact with the sulfur dioxide-containing gases and before regeneration.

Title: Opto-electronic focus detection system
IPC: G02B7/28
Filed: 1975-08-06
Abstract: In an opto-electronic focus detection system for determining a deviation between the plane of focussing of an objective and a radiation-reflecting surface the path of a focussing beam which is reflected by said surface includes an assembly of two radiation-sensitive detection elements. The difference in the output signals of said elements is proportional to said deviation. By disposing a lenslike element of which only the outer zone has a lens action before the detection elements, the measuring range can be extended while maintaining the sensitivity for small deviations.

Patent ES-445241-A1 (ES)
Title: System powered actuating means for butterfly type damper
IPC: F24F11/04
Filed: 1976-02-17
Abstract: A conduit with inlet and discharge ends respectively for receiving a supply of air under pressure and for delivering the air at a lower pressure has a cylindrical configuration and an eliptical butterfly type damper is disposed diagonally therein. The damper turns about an axis intermediate its diagonally opposite ends and the oncoming air stream thus impinges on the upstream face of the damper on opposite sides of the axis and creates a differential force, the said differential force tending to close the damper and constituting a first closing force. A second closing force for the damper is provided by a small bellows supplied with air through a small conduit from the downstream side of an orifice member disposed in the main conduit upstream of the damper. A second and substantially larger bellows serves to open the damper and a small conduit connects the said bellows with a controller supplied with air from an upstream side of the orifice member in the main conduit. The controller regulates pressure in the large bellows as determined by a pressure drop signal across the orifice member and a thermostat. The thermostat vents air from the controller to reduce large bellows pressure for damper closing operation and, conversely, the large bellows is pressurized to cause the butterfly damper to move in the opening direction.

Title: Inking mechanisms for presses
IPC: B41F31/04
Filed: 1979-04-06
Abstract: Ink is contained in a reservoir (27) which is formed by an ink drum (4), which turns clockwise during operation, and a doctor blade assembly (20, 24, 25). The gap between the ink drum and the doctor blade (25) controls the ink film thickness on the ink drum and is adjusted by means including a step- down mechanism. The doctor blades may be each only 5 mm to 10 mm wide, and contiguous with one another to form a full-width blade edge. The edges of the individual blades can be moved towards or away from the ink drum by a rocking of the blades, permitted by flexing of a thin tongue of each blade or blade support, by which the blade is mounted. The rocking is controlled by an adjusting screw (18) and step-down is achieved either, as shown, by a lever arrangement, or by two screw threads of different pitch. Separators (15, 16, 17) can be mounted to divide the ink reservoir (27) into portions extending along different parts of the length of the ink drum (4). Alternatively, diluent or pigment may be added zone-wise to produce a zone-wise distribution of ink.
