Title: Composition and process for displacement plating of zinc surfaces
IPC: C23C18/16
Filed: 1973-11-06
Abstract: Disclosed is an improved composition and process for the heavy metal displacement plating of a zinc surface. The improved process provides for contacting the zinc surface with a solution containing at least one soluble stabilizing compound containing antimony, tin, copper, lead, germanium, vanadium, arsenic or tungsten. This contact may be effected either by pretreating the metal surface prior to displacement plating or by including the stabilizing compound in the displacement solution itself. The composition is an aqueous one containing both a heavy metal ion and the stabilizing compound. The disclosed process improves the displacement plating composition's resistance to degradation and consequent loss of efficiency.

Title: Drying device for fruits - on roller conveyor with hot air directed upwards thus reducing contact pressure
IPC: F26B3/04
Filed: 1976-10-11
Abstract: Fruit drying device for use during certain phases of the treatment cycle e.g. after wshing, after a fungicidal treatment or after waxing comprises a roller conveyor, mounted on shafts, which in turn are supported by a chassis. Air is drawn in by a fan and introduced under pressure into a heating chamber it is brought up to the predetermined temp. and directed uniformly and completely in the direction of the upper part of the conveyor. The heated air traverses the spaces between the rollers of the conveyor impinges upon the fruit and dries it. The air has a lifting effect and reduces the pressure of the fruit on the rollers, this is partic. important after waxing so that the least possible amt. of wax is removed by contact with the rollers. The dimensions of the device are considerably reduced as compared with those of the tunnels used previously. With the internal heating devices the fruit is subjected to the hot air flowing upwards, less power is needed because of the more rational use of the hot air.

Title: System for and method of reproducing an image.
IPC: G03G15/32
Filed: 1980-03-21
Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.
Patent ES-8104553-A1 (ES)
Title: Cartridge extractor for firearms.
IPC: F41A15/14
Filed: 1980-04-08
Abstract: A cartridge extractor, comprising a resilient ring segment formed with a claw, is mounted within a recessed bolt face without a rivet. The wall of the bolt recess is formed with an arcuate clearance cut, radius cuts at either end of the clearance cut, and projecting lobes at the junctions of these cuts. The extractor ring has its free ends bent to form detent arms, which are seated in the radius cuts to support the claw in a position to engage a cartridge base as it enters the recess. This deflects the ring into the clearance cut, guided by the detent arms sliding over the lobes. When the claw seats in the extraction groove of the cartridge, the ring is guided back to its original position by the detent arms re-seating themselves in the radius cuts. For use in auto-loading firearms whose bolts rotate violently, a means is added to prevent relative rotation of the extractor ring, without interfering with its normal deflection. This may be a pin or a protrusion extending into the clearance cut, or a tail on the extractor engaged in a hole in the bolt.
