Title: Auxiliary dynamic compensation devices for gravimetric dispensers
IPC: G01G17/06
Filed: 1977-03-15
Abstract: An auxiliary dynamic compensation device for a gravimetric dispenser, comprises a piston suspended by a pliant and non-extensible connection which is adapted for attachment to the beam or equivalent weighing member of the weighing device of the dispenser and is vertically movable with limited lateral clearance in a vessel containing a liquid in which the piston does not float.

Patent ES-467163-A1 (ES)
Title: Coupler for toy and model railway cars
IPC: A63H19/18
Filed: 1978-02-21
Abstract: A coupler for toy and model railway cars includes a pivotable coupler member having a coupler knuckle adapted to engage a complementary knuckle on an adjacent car. The coupler member is mounted for pivoting movement between a lower position substantially parallel to a trackway and an upper position and is normally maintained in the lower position by magnetic attraction existing between two permanent magnets secured, respectively, to the coupler member and to a support. Cars may be uncoupled by providing a pole of an uncoupling magnet on the trackway to attract at least one pole of the coupler member magnet to torque the knuckle to the upper position and thereby effect uncoupling. The coupler knuckle includes a projection formed on its lower side which is adapted to engage and hold the adjacent complementary coupler knuckle when cars are being pulled in a normal running mode to prevent the knuckles from unintentionally disengaging when coupled cars pass over the uncoupling magnet. The coupler member also includes an inclined ramp surface on the lower surface of a support shaft. When a coupler member is in its upper position, the inclined ramp surface is adapted to contact the fore end of the complementary knuckle to permit one car to push an adjacent car without the cars being coupled to one another. Cars may be pushed to a desired location and left by the pushing car without recoupling of the knuckles.

Patent ES-488296-A1 (ES)
Title: Solar collector.
IPC: F24J2/46
Filed: 1980-02-06
Abstract: The solar radiation heats through a transparent wall, a black body placed on a support containing a heat-exchanging liquid, or a black body on which air to be heated circulates. The black body is constituted by a set of parallel channels 10 containing a heat-exchanging liquid, activated alumina 7 being placed in a passage 8 providing for communication between the volume 6 of air inside the collector, and the external atmosphere, this passage 8 being made in a support wall 1 of the channels 10. The activated alumina dries the external humid air which enters the inside of the collector when the temperature of the internal air falls, which avoids condensation of humidity on the internal face of the transparent wall and protects the efficiency of the collector. Conversely, when the temperature on the inside of the collector rises, the hot air escapes to the outside, regenerating the drying power of the activated alumina.

Title: Print velocity control apparatus for single element impact printers.
IPC: B41J1/60
Filed: 1980-12-24
Abstract: The mechanism disclosed herein is capable of adjusting the velocity with which a print element is projected toward a record sheet such that the impact velocity and, thus the impact forces, are controlled and varied. The control of the velocity with which the print element located on a shaft (22) is propelled against the record sheet is accomplished by a cam (26) which rotates with the print element during character selection and has thereon a plurality of rises corresponding to a displacement of a cam follower (30) engaged with a print cam (12). The print cam (12) is formed to present, in a plurality of different planes perpendicular to its axis, a like plurality of cam profiles and rises. By shifting the print cam follower (30) from one plane to another along the axis of the print cam (12) the velocity of the print element may be selected and controlled. This velocity selection is a direct result of the amount of rise in the cam (26) attached to the shaft (22) which rotates the print element.

Patent ES-8300298-A1 (ES)
Title: Air reject gate.
IPC: B65H29/58
Filed: 1982-01-08
Abstract: A gate station incorporates air pressure flows to direct clips in a production stream through the station and to selectively divert defective clips into a separate reject steam. Mounted on a support plate in the station are an upstream manifold, continuously supplied with low pressure air, and a downstream manifold, having a plurality of downwardly directed air ports and selectively supplied with high pressure air. Air flow from the upstream manifold is directed laterally over the upper surface of a clip so as to enable atmospheric pressure to maintain the clip travelling through the gate station in the production stream. If a clip is to be diverted, the downstream manifold is injected with high pressure air causing blasts of high velocity air through the downwardly directed ports. This high velocity air disrupts the flow from the upstream manifold and forces the leading edge of the defective clip downwards, pressing the clip into the reject stream.
