Title: Method for making a scroll type housing for a centrifugal blower
IPC: B21D53/78
Filed: 1976-04-27
Abstract: A method for making a scroll type housing for a centrifugal blower wherein a flat discharge plate is provided with a rectangular discharge opening and a pair of lugs are spaced from each of a first pair of opposing parallel edges of the opening. Narrow upstanding flanges along the edges are spaced slightly from the lugs and the second pair of opposing edges of the opening are each provided with a narrow elongated portion which is offset to a shallow depth in the direction of the flanges. A scroll member is provided in an elongated generally flat flexible sheet of material with a narrow end flange formed integrally along each end edge. The flanges project generally in the same direction and the member also has a reverse bend adjacent one end approximately in the form of a desired final configuration of a "cut-off" section of the housing. Three lanced openings are spaced apart along each side edge of the member. The scroll member is bent arcuately and the flanged ends thereof are brought toward each other and inserted through the opening in the discharge plate so as to reside respectively in the offset portions. Thereafter, a pair of similar flat side plates formed of sheet material in a scroll configuration and with linear edges at their discharge ends are assembled within the scroll. A first side plate has its linear edge entered between an adjacent flange and pair of lugs with the opposite end of the plate inclined within the scroll and the plate is then urged to a final upright position at the scroll edge. Three lugs on the plate enter the three openings in the scroll and the plate is thus held in assembled position. The second side plate is then assembled within the scroll in an identical manner.

Patent ES-466157-A1 (ES)
Title: Quick-closure coupling for hydraulic lines
IPC: F16L37/00
Filed: 1978-01-19
Abstract: A quick-closure coupling for hydraulic lines in which two insertable coupling halves are lockable in a coupling position, and are constructed in the form of a plug valve and a sleeve valve, each having a closure piece. The closure piece is spring loaded in the closure direction, and held in a closed position when the coupling halves are separated. One of the coupling halves is provided with a stop which restricts a valve stroke of the closure piece in the opening position. The other coupling half has the closure piece loaded with a stronger spring and has a valve stroke equal to twice the opening stroke of the other closure piece. One of the coupling halves has a closure piece which can execute the opening stroke, and has a locking device which is ready to lock due to axial displacement of the closure piece beyond a single opening stroke. After returning the closure piece to its opening position corresponding to the single valve stroke, the locking device reaches a stop position restricting the valve stroke to this opening position. But the locking device is moved back during disconnection of the coupling halves to its release position, permitting thereby a double valve stroke. The locking device may be in the form of a stop spring loaded in a direction of its locking position.

Patent ES-476816-A1 (ES)
Title: Liquid-liquid extraction.
IPC: C07C407/00
Filed: 1979-01-12
Abstract: The invention provides a process and apparatus for liquid-liquid extraction in which a first liquid phase is passed continuously through a series of extraction stages (10) whilst a second liquid phase is passed continuously through the series in counter-current to the first phase. In each stage the second phase is dispersed as by a sieve plate (11) and then allowed to coalesce into a settled body (14) from which the second phase is withdrawn and passed to the next adjacent stage. The invention is characterised by the fact that the flows of the two phases in each stage are generally transverse to each other. Preferably the first phase flows through the series of stages under gravity whilst the second phase is pumped (16) from stage to stage to control its inter-stage transfer. The invention combines the features of separate control of residence time characteristics of an extraction column with the safety aspects inherent in a mixer/settler battery.
Patent ES-484966-A1 (ES)
Title: Slip band electromechanical clutch
IPC: F16D27/02
Filed: 1979-10-11
Abstract: An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member. The driven member carries the engine cooling fan, and the driving member houses a magnetic coil which is energized to actuate the clutch. The driving and driven members define a circumferentially extending gap therebetween. A band is disposed within the gap, and includes an inner band member made of electromagnetic material and an outer band member comprising a resilient member with a frictional material attached to the outer circumference thereof. The inner and outer band members are joined together so that the inner and outer band members may move radially relative to one another while actuation forces may be transmitted from the inner to the outer band to the connection therebetween. When the clutch is engaged, the inner band member is drawn into driving engagement with the driving member by energization of the electromagnetic coil. Accordingly, actuation forces are transmitted from the driving member to the driven member through the inner band member and the outer band member. However, since only a frictional engagement exists between the outer band member and the driven member, the outer band member is permitted to slip relative to the driven member, thereby accommodating any torque overload condition.

Title: Pneumatically operated threading device for a two-for-one twisting spindle.
IPC: D01H15/00
Filed: 1981-10-27
Abstract: The invention relates to a device for pneumatically threading a yarn in a double twist spindle. It is disposed inside a sleeve connecting two tubes adapted to constitute the central shaft of a double twist spindle. A yarn brake capsule passing through the flat rod of a piston is disposed inside the sleeve, its ends abutting against the opening of the bore of one tube and against that of the central hole of an end piece mounted at the end of the other tube. When compressed air is sent into the bore of the first tube, the piston is moved, causing a lateral shift of the yarn brake capsule, thus allowing passage of the yarn along the bore of the spindle. The invention is particularly applicable to double twist spindles.
