Title: Device for counting the number of playing passes of a cassette for tape or film, bearing sound and/or picture or other signals, and/or device for blocking said cassette after a predetermined number of passes.
IPC: G11B23/04
Filed: 1981-12-11
Abstract: A cassette for a strip such as a tape or film, having a pair of spools between which the strip is wound and unwound, is provided with apparatus for counting and limiting the number of times the cassette is played. A feeler assembly is mounted for swinging movement on the cassette cover, between the rolls of strip on the spools, and has two feelers one of which rides on the outer periphery of one roll and the other of which rides on the outer periphery of the other roll. Upon winding and rewinding of the strip, therefore, the feeler assembly oscillates, and in doing so, it actuates an escapement which turns a toothed wheel. The toothed wheel, turning one unit of angular movement with each play of the cassette, records the number of plays by the rotated position of the wheel, which can be read through a window of the cassette, in the form of numerals on the wheel. Two wheels can be provided, one to count the number of plays, and the other bearing at least one abutment which stops the rotation of that other wheel, either by engagement with a fixed abutment on the cassette cover, or else by engaging and hence blocking the escapement in contact with an abutment surface on the wheel. The escapement can be so formed as to register the play only during a midportion thereof, thereby to prevent fraudulent extra use of the cassette by skipping the beginning or end of the strip.

Title: Compatible transcodeable and hierarchical digital TV system
IPC: H04N7/00
Filed: 1982-01-26
Abstract: A digital television system in which siganls are sampled at 13.5 MHz and produce an integer number of samples during each horizontal line interval whether the signals are based upon PAL/S.E.C.A.M. or NTSC standards. In order to make the digital system hierarchical and to adapt it for simple transcoding from an NTSC signal sampled at 4 times color subcarrier, the number of samples occurring during the active portion of each horizontal line in the digital system is made equal to 704. Transcoding by interpolation from 4XCS-sampled NTSC video to the digital system is accomplished by selecting a particular number of samples per active line namely 748 such that small blocks of samples can be transcoded independently, which allows interpolation to be achieved simply. A similar transcoding scheme is also described for PAL signals.

Patent ES-8500752-A1 (ES)
Title: Emergency locking reels for belts.
IPC: B60R22/36
Filed: 1983-05-04
Abstract: An emergency locking reel for a safety belt and being of the kind having a frame which is securable to a support, a spool rotatably mounted on that frame, and locking means operable to prevent rotation of that spool in a belt unwinding direction. The locking means comprises a toothed ring secured to the frame and a pawl rotatable with the spool and movable relative thereto to engage the ring. According to the invention, an inertia plate is provided separate from the pawl and is mounted on the spool spindle for limited relative rotation. A ratchet wheel is connected to the pawl for rotation therewith and carries a detent which responds to relative rotation between the wheel and inertia plate to stop rotation of the wheel and thereby cause the pawl to engage the ring. A spring resists that relative rotation between the wheel and inertia plate. The housing for the locking means is symmetrical about a plane which contains the spindle axis and a sensor responsive to vehicle deceleration is also located on that plane. The sensor is securable to the housing in any of a plurality of positions without disturbing the aforementioned symmetry. Furthermore, each tooth of the locking ring is symmetrical about a plane containing the spindle axis. An end plate of the housing has, as integral parts, a bearing for the spindle and locating means for the locking ring and sensor respectively, thereby simplifying assembly of the reel. A wedge-type retainer secures an end of the belt to the reel by locating in a slot of the spool and clamping the belt in three separate zones.

Title: Hitch control system for an agricultural vehicle.
IPC: B60K25/02
Filed: 1984-06-12
Abstract: Clockwise and anticlockwise rotation of a shaft (14) and lever (26) fixed thereto lower and raise a three-point hitch via a conventional rockshaft valve and lift cylinder. Working depth of an implement on the hitch is set manually by a frictionally-restrained lever (20) coupled to the lever (26) by a link (30) which is pivoted (32) on the lever (20) and coupled to the lever (26) by a slot (36) engaging a pin (28) on the lever (26). A bellows actuator (42) has a rod (64) which is urged to the left by a spring (68) and to the right by a differential pressure across a water pump (11) of the tractor engine (10). If the engine labours and its speed drops, the differential pressure falls, the rod (64) moves to the left, pushes the link (30) clockwise about its pivot (32) and therefore pushes the lever (26) and shaft (14) anticlockwise to raise the hitch. By thus using coolant pressure as a measure of engine speed a simple means of implementing draft load control is provided.
