Patent ES-8100137-A1 (ES)
Title: Apparatus for cutting sheet material with variable gain closed loop
IPC: B26D5/00
Filed: 1980-03-01
Abstract: An apparatus for cutting limp sheet material with a rigid, cantilevered blade that is reciprocated as it advances along a cutting path through sheet material employs a load sensor to measure lateral loads applied to the blade by the sheet material during cutting. A load signal from the sensor is applied to the blade controls through a variable gain feedback circuit and causes the blade to be oriented slightly toward the side of the cutting path from which an unbalanced load is applied. The adjustment of the gain in the feedback network is made by means of speed sensors which measure the rate at which the cutting blade advances through the sheet material and adjust the feedback gain in inverse relationship.

Title: Oxygen refining of ferrosilicon - using oxygen-contg. additive for aluminium and calcium removal (NO 14.6.83)
IPC: C22C33/00
Filed: 1981-11-17
Abstract: The parent patent describes a method of removing aluminium and calcium from silicon and its alloys contg. at least 60% Si by treatment with oxygen in a ladle having a double tuyere, oxygen being injected through the central tuyere tube while a protective fluid is injected through the annulus between the two tuyere tube. In the present invention, the oxygen additionally contains a substance contg. at least one active atom, selected from oxygen, chlorine and fluorine, which is liberated by thermal decompsn. at the temp. of the silicon alloy and which combines with aluminium and calcium to give a volatile or slag-forming cpd. The process reduces the aluminium content to 100 ppm. or even 50 ppm., compared with 600-900 ppm. for the parent patent process, so that it is esp. useful for treating ferrosilicon which is to be used to make grain-oriented magnetic strip for low loss transformers (having a loss of max. 0.6 W/kg per strip at 50 Hz and 1 Tesla).

Title: Round baler.
IPC: A01F15/14
Filed: 1983-05-27
Abstract: An automatic twine-wrapping mechanism for a large round baler. The mechanism comprises (1) a twine dispensing mechanism for dispensing twine into the bale-forming chamber of the baler, (2) a reversible hydraulic drive means for cycling a twine arm of the dispensing mechanism back and forth in front of the chamber, (3) a twine wrapping control mechanism (a) for initiating a twine wrapping cycle by sensing the growth of a bale to a predetermined diameter by automatically actuating a pump drive means for driving a hydraulic pump and by positioning a hydraulic control valve to condition the hydraulic drive means to cycle the twine arm and (b) for terminating a twine wrapping cycle by deactivating the hydraulic drive means following the wrapping of twine around the bale.

The baler operator actuates a bale ejection mechanism following the cutting of the twine. Following bale ejection, the twine wrapping cycle is terminated by the twine wrapping control mechanism sensing that the bale chamber is empty. The baler is now ready to begin the formation of another bale therein.

Patent ES-8503835-A1 (ES)
Title: Method of recovering solvent vapour.
IPC: F26B21/14
Filed: 1984-03-30
Abstract: A gaseous stream comprising nitrogen and solvent vapor istaken from a curing oven (not shown), is passed through preliminary heat exchangers 13 and 23, and enters a first heat exchanger 33 through conduit 30. Remaining vapor is condensed in the heat exchanger 33 by heat exchange with chilled medium entering the heat exchanger from conduit 52 and leaving via conduit 37. The medium then enters a second heat exchanger 43 via conduit 42 where it is chilled by liquid nitrogen supplied via conduit 47, the chilled medium being recycled to the first heat exchanger. The resulting vaporised nitrogen is supplied to form gas curtains at the entrance and/or exit of the oven. This nitrogen leaving the first heat exchanger 33 is used to supply a return stream to the interior of the oven at a rate that substantially matches that at which nitrogen is withdrawn from the oven. This enables a mass balance to be maintained in the oven atmosphere.

Patent ES-8505055-A1 (ES)
Title: Slack adjuster for a disc brake.
IPC: F16D65/46
Filed: 1984-06-15
Abstract: A slack adjuster is for a disc brake of the type which includes a disc mounted for rotation about an axle and a caliper brake having a housing mounted on the axle in alignment with a friction surface of the disc. A braking piston is mounted in the housing for axial movement toward and away from the friction surface of the disc. Brake actuation produces rotating movement of a powershaft mounted in the housing which will in turn produce a corresponding axial movement of the braking piston through a non-rotating powershaft nut. An adjusting sleeve is between the piston and the powershaft nut and is threadably coupled to the piston and capable of rotation relative thereto to adjust the axial position of the piston. The adjusting sleeve is capable of rotating in a direction which will cause the piston to be adjusted toward the disc and is prevented from rotating in the opposite direction by a one-way clutch shaft between the adjusting sleeve and the housing. A lost motion element allows rotation of the powershaft to produce corresponding rotation of the adjusting sleeve after the piston has moved toward the disc through a desired running clearance without having made any frictional contact therewith and employs a force limiting clutch element to prevent corresponding rotation of the adjusting sleeve when the powershaft is rotated in a direction to produce movement of the piston away from the disc. The clutch shaft can be selectively operated in both directions for initial adjustment of the adjusting sleeve.
