Patent ES-8104152-A1 (ES)
Title: Method and apparatus for handling glass sheets during shaping and cooling
IPC: C03B35/14
Filed: 1980-06-11
Abstract: This invention relates to improvements in handling glass sheets during shaping and cooling. Each glass sheet in turn is heated to its deformation temperature and conveyed into a glass shaping station. The glass is lifted into engagement with an upper vacuum shaping mold while hot and held against the vacuum shaping mold by vacuum as the glass lifting mechanism retracts downward. A transfer and tempering ring-like member having stop means upstream of an outline supporting surface conforming to and slightly inside the periphery of the bent glass sheet is brought into a position where its stop means are slightly misaligned upstream of the trailing edge of the glass sheet. The vacuum on the upper mold is released to deposit the shaped glass sheet on the ring-like member. The latter starts suddenly to displace the bent glass sheet into proper alignment with the ring-like member for movement into a cooling station where the shaped glass sheet is quenched as rapidly as possible to harden the glass surface and then transferred to an unloading conveyor at a transfer station. The ring-like member starts its rapid return from the transfer station to the shaping station before the shaped glass sheet is transferred to a position completely downstream of the ring-like member.

Patent ES-8206797-A1 (ES)
Title: Lubricant oil automatic supply control type piston ring
IPC: F16J9/20
Filed: 1981-10-09
Abstract: A piston ring (5) inserted in a groove in an internal combustion engine piston (3) comprises at least two materially joined piston-ring discs (6, 7) arranged axially in series. In addition, this piston ring (5) can be compressed with a uniform axial intensity over its entire circumference in a partial, outer radial region. This compressibility is provided by the presence of at least one radially encircling, outwardly open annular gap (13) at the level of the plane in which the piston-ring discs (6, 7) are joined. At low pressure in the cylinder, this gap takes up lubricating oil. When the piston ring (5) is subjected to the gas pressure acting in the combustion chamber of the internal combustion engine, this lubricating oil is forced out of the annular gap (13) into the space (25) between the sliding surface (26) of the piston ring and the sliding surface (2) of the cylinder due to an axial constriction of the annular gap resulting from the said gas pressure. The piston rings (5) thus have a self-lubricating action controlled as a function of the gas pressure in the cylinder, thereby reducing wear both on the piston rings (5) themselves and on the sliding surfaces (2) of the cylinder.

The one-way package is particularly suitable for use in a beverage vending machine in place of the storage containers employed until now. A suspension flap 12 of the box, which can be separated away from one of the broad sides, serves for interchangeably securing the container in the vending machine for the extraction of the fluid.

Title: Method for preliminary anchoring of a wire rope bolt
IPC: F16G11/00
Filed: 1983-08-01
Abstract: The invention relates to a method and mechanism for preliminary anchoring of a wire rope bolt in a bore by means of friction. The object is to eliminate the need to use wooden wedges or to bend the strands of the rope backwards, procedures which are time-consuming. In accordance with the invention, a permanent deformation is produced in the wire rope bolt in such a way that friction force is produced when parts of the bolt press against the wall of the bore. The mechanism may comprise, fitted at a point prior to feeding rolls, a bending roll, which bends the wire rope before it is fed into the bore. The circumference of the feeding roll can be V-shaped, in which case it causes the bent wire rope to rotate and to become helical.
