Patent ES-438618-A1 (ES)
Title: Pilot valve operator for safety relief valve
IPC: F16K17/10
Filed: 1975-06-16
Abstract: A pilot valve for controlling main valve operation to relieve overpressure from a fluid system to which the main valve is connected. Opening and closing of the pilot valve is effected by a movable disc which carries with it an annular resilient gasket. A seating surface, defined on the end face of the inlet nozzle, cooperates with the gasket when the disc is in closed position for effecting a pressure tight seal against fluid flow to the discharge side of the valve. A perforated gasket retainer communicates exposure of upstream pressure to diirectly against the formed seal whereby at incipient lift of the disc initial flow discharge incurs minimum pressure drop therepast. A two-stage huddle chamber surrounding the seal area is capable of responding to the fluid pressure of even initial discharge to accelerate full lift opening of the disc.
Patent ES-443343-A1 (ES)
Title: Apparatus for forming tampons and assembling same in inserters
IPC: A61F13/20
Filed: 1975-12-10
Abstract: Apparatus and procedures for continuously forming rosette shaped tampons from aggregate containing tubular sacks or overwraps having withdrawal strings at one end and assembling the tampons in inserters, the apparatus comprising rotary transfer mechanism for engaging the withdrawal strings of the sacks and sequentially delivering them to a rotary assembly turret having a multiplicity of assembling stations mounted around its periphery. Each inserter comprises inner and outer parts, and feeding means are provided to individually feed and position an inner inserter and an outer inserter in holders at each assembly station. Each station has a reciprocating string engaging rod which acts to remove a sack by its string from the transfer mechanism and positions the sack to be drawn upwardly by vacuum into an overlying annular inversion chamber wherein the sack is inverted into rosette shape by the action of a pressure-vacuum reciprocating inversion rod. The shaped sack is then moved downwardly into an underlying compression cone wherein it is radially compressed and drawn downwardly into an underlying cylindrical compression chamber, whereupon the outer inserter is positioned to overlie the compression chamber and the inner inserter, which underlies the compression chamber, is moved upwardly by a reciprocating assembly rod which causes the inner inserter to push the compacted tampon upwardly into the overlying outer inserter, and at the same time the upper end of the inner inserter engages within the outer inserter to complete the assembly. The assembled inserter is then transferred from the assembly station to a discharge wheel for delivery to a collection station or other mechanism for wrapping, packaging, or the like as the rotary assembly turret completes it cycle of operation.

Title: Method for producing needle feldle and patterned non wovenfabric
IPC: D04H1/4291
Filed: 1977-04-06
Abstract: A single-colour needled length of fibre web and at least one other length of fibre web which contrasts in colour, is likewise needled and has on one of its two surfaces ornamentally patterned areas of fibres which are bonded or heat-welded together, are placed one on top of the other and needled together, from the direction of the length of fibre web which has no areas of fibres which are bonded or heat-welded together, to give a nonwoven. The lengths of fibre web to be needled together are laid one on top of the other in such a way that the surface, which has areas of fibres, which are bonded or heat-welded together, of the length(s) of fibre web having such, faces away from the length of fibre web containing no bonded or heat-welded fibres. This produces an ornamental pile structure with contrasting colours on the surface which forms the visible area of the finished nonwoven and has ornamentally patterned regions with bonded or heat-welded fibres.

Patent ES-458046-A1 (ES)
Title: Power transmitting mechanism
IPC: F16H15/50
Filed: 1977-04-21
Abstract: A power transmitting mechanism for converting the thrust of reciprocating pistons to a rotary output shaft at speeds independent of the frequency of piston reciprocation. Power developed by expanding gases in accordance with well-known thermal cycles, such as the Stirling cycle, is transmitted by pistons to a bed plate capable of swashing motion about a point on the axis of the output shaft. The shaft is provided with a pair of oppositely convergent or biconical friction surfaces engageable by annular tracks carried with the bed plate in orbit which may be characterized as nutational. Axial adjustment of the annular tracks toward and away from the point on the output shaft varies the output shaft speed independently of input speed or piston frequency.

Title: Protective device for an electronic junctor
IPC: H04M3/18
Filed: 1978-01-10
Abstract: A circuit for protecting a telephone junctor from excessive alternating or direct current voltage includes a diode bridge connected to the junctor. A first threshold detector connected to the diode bridge detects excessive positive voltages and a second threshold detector connected to the diode bridge detects excessive negative voltages. The output of the two threshold detectors are applied to a temporization circuit which inhibits an over-voltage indication signal from being generated by transient over-voltages. The temporization circuit also sustains an over-voltage indication signal when the signal waveform of an alternating-current over-voltage passes through zero. A circuit responsive to an over-voltage indication signal inhibits application of power to the junctor circuit.

Title: Process for obtaining new strains of yeast for bread-making and novel strains of yeast thus prepared
IPC: C12N1/18
Filed: 1977-12-23
Abstract: A complete and reproducible process for producing novel strains of yeast, comprises making a first screening test and at least one other screening test selected from a group of screening tests which do not resort to any measurement of gas release, selecting by means of said first and at least one other said screening test the desired strains from a group of diploid strains prepared previously either by hybridation, or by mutation of existing strains. The tests are as follows: A first test consists of measuring the average multiplication coefficient of a given strain by following the optical density variation of a standard medium seeded by a suspension of cells obtained from this strain. A second test consists of measuring in the same manner the average multiplication coefficient of the said strain in the presence of an inhibitor acid added to the standard medium. A third test consists of measuring the maltose adaptation of said strain in the presence of glucose by determining the amount of maltose subsisting in a standard medium after a known amount of glucose added to this medium has been completely consumed. A fourth test consists of measuring the invertase content of said strain. A fifth test consists of measuring the latent time of said strain. The hybridation can consist of systematic haploid crossings derived from quick Saccharomyces Cerevisiae strains adapted to maltose and haploids derived from very slow strains not adapted to maltose, but well adapted to sweet doughs and sometimes also to acid doughs.

Title: Device for provisionally consolidating a gallery and suitable consolidating frame
IPC: E21D11/40
Filed: 1978-10-03
Abstract: The invention refers to a device with which provisional consolidating frames adapted to be brought to a smaller size can be transported to the drift face and can be put in place. According to the invention this device is arranged on the cutting machine itself so that the narrow space remaining between the contour of the cutting machine and the cross section of the drift is sufficient for transporting in forward direction and putting in place the provisional consolidating frames without the necessity to retract the face advancement machine from the drift face. Thus, face advancement machines can be used which occupy the major part of the inside width of the drift, noting that the face advancing machine is maintained in its working position. The invention further describes a doorjamb frame for the provisional drift consolidation and which is particularly suitable for the device proposed.
