Patent ES-8303992-A1 (ES)
Title: Sliding walls of vehicles or containers, in particular railway freight wagons
IPC: B61D19/00
Filed: 1982-04-27
Abstract: Guide rails 4, 5 for sliding wall sections 1, 1 are arranged in mirror- symmetrical positions on a shaft 3 which is rotatable to cause the rail 4 to engage rollers 2 of the wall section and move the latter into a sliding displacement plane with the rail 4 then taking up the position originally occupied by the rail 5. The rail 4 is thus aligned with longitudinally adjacent rails 5 to enable the sliding wall section to move in front of wall sections still in their closed positions. Cams 6 mounted on the shaft 3 engage the associated wall section when the latter is being moved into its closed position and serve to lift and retain the closed wall section with its rollers clear of the rail 4. A claw secured to the wall section may be arranged automatically to engage an aperture in the rail 4 so as to prevent longitudinal movement of the wall section in its closed position. A torsion spring may act on the rotatable shaft 3 to reduce the effort required to overcome the weight of the wall section.
Patent ES-8305666-A1 (ES)
Title: Fabricating laminated safety glass without an autoclave
IPC: C03C27/12
Filed: 1982-05-31
Abstract: This invention relates to the lamination of large glass sheets using plasticized interlayer material without the use of autoclaves. Excess liquid plasticizer is applied to the major surfaces of a sheet of plasticized interlayer material to soak the major surfaces at room temperature for sufficient soaking time to soften the surfaces so that the interlayer becomes more amenable to adhesion to glass sheets, but insufficient time to normalize the plasticizer content throughout the thickness of the plasticized sheet. The interlayer sheet is assembled between a pair of glass sheets and the excess plasticizer is removed by compressing the assembly before the soaking time is excessive and the plasticizer concentration can normalize throughout the thickness of the plasticized interlayer sheet. With the excess liquid plasticizer at the interfacial surfaces only, the assembly is subjected to a temperature range above room temperature and below the temperature at which the plasticizer develops a volatile product and a superatmospheric pressure not more than two atmospheres. This removes excess plasticizer from the interfacial surfaces so as to limit the increase in normalized plasticizer content and also permits the sheets to be laminated to one another.

Abstract: A document sheet feeding and registration apparatus and method are described for deskewing a document sheet (7) relative to a desired copying position on a copier platen (3) while feeding the document sheet onto the platen into said copying position. The method and apparatus include obtaining an electrical signal corresponding to the actual velocity of the document sheet (7) being fed onto the platen (3), and actuating an automatic document sheet deskewing device (16, 17) at a precise actuating time occurring sligntly before the document sheet reaches the copying position, so that the actuating time of said document sheet (7) deskewing corresponds to the actual velocity of the document sheet.

The actuating time of the document sheet deskewing device may be a resettable time delay count after the actuation of said second switch (31), which time delay count is resettable by a change in the counted time period between the actuation of said first and second switches (30, 31). The automatic document sheet deskewing device (16, 17) may comprise a releasable skew preventing document feeder (17) releasing the document sheet (7) at said actuating time to another feeder (16) for briefly driving the document sheet (7) into a registration aligning edge (18) while freely allowing deskewing movement of the document sheet (7) thereagainst after said actuating time.

Title: High voltage protection for an output circuit
IPC: H04N5/14
Filed: 1983-08-23
Abstract: A protection circuit is coupled between a low voltage signal processing semiconductor device subject to damage by high voltage transients, and a signal output terminal at which high voltage transients can appear. The protection circuit comprises a first transistor arranged as an emitter follower for normally conducting signals from the semiconductor device to the output terminal, and a second transistor of opposite conductivity type. The base and emitter electrodes of the first transistor are directly connected to the base and emitter electrodes of the second transistor, respectively, such that the second transistor is normally non-conductive. Transient currents associated with negative high voltage transients at the output terminal are diverted to a point of operating potential via the first transistor. The second transistor is rendered conductive in response to positive high voltage transients at the output terminal for diverting associated transient currents to a point of operating potential.
