Patent ES-486330-A1 (ES)
Title: Trailed agricultural implement
IPC: A01B63/22
Filed: 1979-11-26
Abstract: The rear end of the oblique frame of a multi-share plough is supported by a land wheel 48 and a rear furrow wheel 36 on leading and trailing pivoted arms 40 and 30 respectively. The wheels are lowered and raised together, to raise and lower the frame respectively, by a double-acting hydraulic cylinder 66 which rocks an arm 62 clockwise to raise the wheels. The arm 62 then pushes an arm 58 clockwise, the arm 58 being integral with the land wheel arm 40, and pulls the arm 30 anticlockwise by a link 78. When the cylinder rocks the arm 62 anticlockwise the wheel 48 rises faster than the wheel 36 (because of different lever arm ratios) until the arm 40 hits a stop 92, this being the illustrated position. This tilts the beam carrying the arms 30 and 40 and rolls the frame in the sense tilting the share points 22 into the ground. Lost motion between the arms 62 and 58 allows the wheel 36 to finish rising so digging the shares into working depth while levelling off the tilt which has helped them to dig in efficiently.
Patent ES-8100162-A1 (ES)
Title: Apparatus for treating the surface of cylindrical objects.
IPC: G03F7/40
Filed: 1980-02-08
Abstract: Apparatus for treating the surface of a cylindrical object (e.g. an exposed photopolymer printing sleeve) in a number of sequential steps. A plurality of cylinders are supported in an enclosure one each on a plurality of carriers (8 to 11) rotated by a transmission from a motor (48). Each cylinder is rotatable past a hot air drying inlet unit (55, 56), an ultraviolet exposure unit (53) and a unit (58,59) for spraying a detackifying solution. The units are operational in required sequence for simultaneously and equally treating the surface of each cylindrical object.
Patent ES-8104097-A1 (ES)
Title: A power assisted gear assembly.
IPC: B62D5/30
Filed: 1980-07-22
Abstract: A power assisted steering gear assembly having a first fluid system 5 comprising a first pressure operated device such as a double acting piston and cylinder, a first valve for controlling fluid flow to the first pressure operated means in response to a steering input in shaft 2 and a first fluid pump 7. The first pressure operated means can be a conventional power assisted steering gear 1 imparting rotation to a drop arm 8. A second fluid system 20 comprises second valve means controlling fluid flow from a second pump 26 to a second piston and cylinder device incorporated in a ram unit 12. The second valve in the ram unit 12 is responsive to displacement of the drop arm 8 and reacts to determine power assistance provided by the system 20 to a steering maneuver, such power assistance being additional to that provided by the system 5. Displacement of the ram unit 12 controls movement of a steering linkage through drag link 38. In a modification the system 20 can include an auxilliary valve which is responsive to fluid pressure in the system 5 so that when that pressure attains a predetermined value the auxilliary valve reacts to render ineffective power assistance from the ram unit 12. In the event of fluid pressure failure in the system 5 the auxilliary valve reacts to restore pressure fluid to the ram unit 12 and provide power assistance in the system 20.

Title: Continuously operating system for scouring cloth, knitted fabric and the like.
IPC: D06B3/20
Filed: 1980-10-01
Abstract: In the technical field of machines for treating fabrics or the like while being processed, there is provided a system for continuously scouring woven or knitted fabrics, in their flat or tubular condition, which can be used in the preparation, mercerization, scouring after dyeing and after printing, as well as during the final finishing stage. The technical problem faced is that of providing a system of a truly universal type and with a specially efficient scouring action, such that no tension is exerted on the fabric being scoured, while allowing the fabric to change its shape spontaneously. The solution to the problem consists of providing a system which comprises a plurality of parallel and closely adjacent rollers (3, 4) such that they cause the fabric (2) or the like to follow a path of substantially continuous contact with the rollers (3, 4), which are all driven in a non-rigid manner, and comprises means (5, 8, 4, 3) adapted for subjecting the fabric simultaneously to three different types of scouring action.

Patent ES-8406230-A1 (ES)
Title: Device for coating a continuous web
IPC: B05C5/02
Filed: 1983-11-11
Abstract: A device for coating a continuous web that travels over a back-up roll. The force of application can be adjusted. The coating material is applied to the web with a slotted applicator pipe. The pipe extends over the width of the web and has a preliminary coating-material flow-regulating gap. The width of the gap can be adjusted. A coating-material flow-regulating lip and a return lip adjoin the gap in such a way as to constitute a coating-material flow-regulating chamber extending over the width of the web. The flow-regulating lip is a doctor bed and has a doctor batten that moves with little friction along at least one overflow-side slide face. The face of the doctor batten toward the web that is being coated is rectangular and demarcates in conjunction with the web a narrowing wedge-shaped gap with a geometry that depends on the degree of contact pressure. The overflow edge of the face is a straight and sharp stripping edge. The face and stripping edge of the doctor batten are flexible. Its face is highly resistant to wear. The doctor batten is forced against the web by an inflatable means of exerting contact pressure between the batten and the bed.

Title: Videotext system with public terminals.
IPC: H04M11/08
Filed: 1983-11-30
Abstract: In public videotex (Btx) terminals, different pages are displayed successively on the screen in the off-line mode (e.g., advertisements and user instructions). To be able to update such off-line pages at low cost, a page memory in the terminal is constructed as a random-access memory (46). A central operating facility contains an editing device in which the information and control characters required to display an off-line page are produced. These characters are transmitted to the terminal and written into the random-access memory (46). This may be effected automatically when the supply voltage is turned on.
Patent ES-8406823-A1 (ES)
Title: Television circuit arrangement for field and line frequency doubling and picture part magnification.
IPC: H04N5/222
Filed: 1983-12-05
Abstract: A television circuit arrangement for field and line frequency doubling and picture part magnification (zooming). In order to obtain the frequency doubling, there is written alternately into two field memories (M1, M2) during a field period comprising line periods at a given writing speed (clock frequency fc), whereby the reading from the field memories takes place at twice the writing speed. For a picture part magnification to be carried out in a simple manner, provision is made of a magnification control circuit (TG, S3, S4, S11, S12) comprising a clock signal change-over circuit (S3, S4), as a result of which during writing there is present a higher writing speed (clock frequency 2fc) than the said given writing speed (clock frequency fc), i.e. during a part of the field periods and of the line periods which is substantially inversely proportional to the ratio between the higher writing speed and the said given writing speed. For intermittent writing, one or more further change-over circuits (S11, S12) can be provided at the memory signal inputs, which provides besides a more effective information storage and an improvement of the picture quality, the possibility of a movement detection and a recursive signal processing for noise reduction.
