Patent ES-371066-A1 (ES)
Title: Liquid fuel injection pumping apparatus
IPC: F02M55/02
Filed: 1969-08-11
Abstract: A rotary cylindrical distributer type fuel injection pump comprises a number of chambers 25 each containing a plunger 26 spring-loaded towards an end of the chamber communicating with an outlet port 17, the other end of the chamber communicating with a pressure source less than that of the injection pressure, and the arrangement being such that pressure variations in the outlet port 17 and pipeline 18 to the injection nozzle 19 are minimized. Fuel delivered from a pumping chamber 12 to the outlet port 17 moves the plunger 26 to its fullest extent against a spring 27, and thereafter fuel is delivered to the injection nozzle 19. At the end of injection, and with the delivery passage 16 and port 17 still in register, the plunger 26 remains in this position until the fuel pressure drops to a predetermined level, whereupon the plunger is moved by the spring 27 to damp pressure waves which occur in the outlet port and pipeline, thus ensuring a more regular delivery volume.

Patent ES-435961-A1 (ES)
Title: Snap-action pushbutton switch
IPC: G06F3/02
Filed: 1975-03-24
Abstract: In a pushbutton switch one conductive plate is formed on a fixedly mounted printed circuit board. The other plate is comprised of a cantilever spring-mounted, movable, conductive, plate parallel with but spaced apart from the fixed plate. A pushbutton, constrained to move along a line perpendicular to the fixed and movable plates, is located opposite to the movable plate with the fixed plate in between. On the back side of the pushbutton is a small permanent magnet having a surface area approximately equal to that of the fixed and movable plates. Upon depression of the pushbutton the magnetic force of the magnet overcomes the spring force of the cantilever springs on the movable plate and snaps it into contact with the fixed plate. A stepwise change in impedance between the two conductive plates produced by depression of the pushbutton is detected providing an indication that the switch has been operated.

Title: Continuous flat plastics article prepn. - with common carrier tape turned for bilateral use of plastic double foils
IPC: B29C69/00
Filed: 1978-04-05
Abstract: Flat articles, made of plastic foil and welded at the contours, are produced by feeding a double plastic foil on a carrier tape into a welding and separating unit. The compound tape is then turned through 180 degrees by guiding it over a drum at 45 degrees to the direction of motion. In a second welding and separating unit, a second double plastic foil is applied to the other side of the carrier tape and used for the prodn. of a second line of articles. Used for mass prodn. of surgical gloves, bags or similar contoured articles with a welded joint on the contours, made of a plastic such as polyethylene. This reduces the mfg. costs of mass-produced articles by doubling the prodn. rate (using two welding units) and by saving high-quality carrier paper (applying articles on both sides of it).
