Patent ES-350893-A1 (ES)
Title: Apparatus for processing wire and the like
IPC: C21D8/06
Filed: 1968-02-24
Abstract: A method of effecting permanent elongation to increase the creep resistance of a metal element, e.g. wire, strand, rope, comprises passing the element under tension around not more than three rotary members 15, 16, rotating at the same angular velocity and having peripheral V-grooves 28, 29, which progressively increase in diameter in the direction of element advancement and the angle between the sides of which is not more than 30 degrees, the element being heated at 35 prior to passing to the largest diameter V-groove 29. The angle between the sides of the V-grooves may be varied by packing strips (30) (Fig. 3, not shown). Wire 37 is fed from a supply reel 38 or 39 to a brake wheel 40, from which it is led to the groove 28 of the rotary member 15 under appreciable tension. After leaving the rotary member 15, the wire is led around an idle wheel 31 and through an induction heater 35 where the carbon steel wire is heated to 220-500 C. If the wire is an alloy steel, it is heated to 600 C. The wire is thereafter cooled in a water bath 36 and led into the V-groove 29 of rotary member 16, from which it is pulled under tension by pairs of wheels 43 having rubber tyres 44. The upper of the two wheels 43 in each pair is mounted in a pivoted arm (80) (Fig. 5, not shown) to permit passage of enlargements on the wire at a joint between lengths of wire. The wire is finally wound on a reel 55 or 56 and is cut by a device 47 when the reel is full. The wire is cut by displacing a valve (69) (Fig. 6, not shown) to pressurize a ram (60a) in a cylinder (60) and manually displacing a detent member (64) into the release position to cause a piston-rod 61, Fig. 7, connected to the ram (60a), to move forward. A die 52 is reciprocated by movement of the piston-rod 61 to cause the wire 37 to be sheared, the free end of the wire in the die 52 being directed to an adjacent hole 51 in a stationary die 49, from where the wire is led to the empty reel 56. An identical cylinder (59) is positioned on the opposite side of the die 52 and is connected to a low pressure pipe (72) during reciprocation of the piston-rod 61 so as not to resist movement of the die 52. When the reel 56 has been filled, the valve (69) is reversed and a detent member (63) moved into the release position to cause a piston-rod (61) to move the die 52 in the opposite direction. Idle wheel 31 may be replaced by a further rotary member, which is connected by gearing to the other two rotary members. The permanent elongation effected may be 2-5%.

Title: Control means for a two-stage servomotor
IPC: F16D65/18
Filed: 1975-06-20
Abstract: A control valve is actuated by a first plunger upon movement of an input push rod to create a pressure differential across a movable wall which produces an output force. The output force is transmitted from the wall to move a stepped diameter piston, the larger diameter of which develops a first pressure force for operating the wheel brakes of a vehicle. When the input force from an operator exceeds the first pressure force, movement of a second plunger interrupts the communication of the first pressure force to the wheels to permit the output force from the wall to further move the stepped diameter piston so that a smaller diameter thereof develops a second pressure force.

Title: Method of and apparatus for producing fibre sheets
IPC: B28B1/52
Filed: 1976-01-16
Abstract: In the production of, for example, asbestos cement boards, a felt belt is guided through a deposition box in which an asbestos cement slurry is disposed. A mat is deposited from the slurry onto one side of the felt belt and the mat is sucked onto the felt belt, for which purpose a suction device is present on the other side of the felt belt. In order now to obtain boards of uniform thickness and strength, a cylindrical screen/couching roll arrangement (18, 19) which compacts and dewaters the deposited mat is disposed downstream of the deposition box (6). The suction of the mat takes place by a subatmospheric pressure which is locally variable in the longitudinal direction and/or lateral direction of the felt belt. To this end the suction box is subdivided into individual boxes (8, 9) which are arranged one behind the other in the conveying direction and, if appropriate, one next to the other across the felt belt width. Preferably an adjustable cover screen (10) is arranged in the deposition box (6), such that a flow channel (11) for the asbestos cement slurry is produced between said cover screen (10) and the felt belt (3). This flow channel promotes the desired irregular orientation and uniform density of the asbestos fibres in the mat.
