Title: Apparatus for raising and lowering a tennis court net
IPC: G07F9/00
Filed: 1969-12-06
Abstract: Apparatus for raising and lowering the net of a tennis court which is incorporated in the post supporting the net. The apparatus includes a hydraulically operable ram and cylinder device, the ram of which is connected to the cord of the net so that the net is raised when the ram is extended. The ram is extended by a manually operable pump. A valve biassed to the open position is located so that fluid pumped from a reservoir into the cylinder is returned to the reservoir through the valve. The valve is closed to trap fluid in the cylinder to enable the ram to be extended by insertion of appropriate coin in a coin-operable mechanism. Operation of the coin-operable mechanism starts a timing device which is operative to open the valve at a predetermined time, usually one hour, after the valve has been closed. When the valve is opened the ram retracts under the weight of the net and/or the effect of a spring to cause the net to be lowered.

Patent ES-431062-A1 (ES)
Title: Decreasing load deflection mechanism
IPC: B65H1/24
Filed: 1974-10-16
Abstract: In the preferred embodiment there is a loading mechanism for providing an initial load on a magnetic card in a card hopper such that when the magnetic card is brought into contact with a feed roller, the card is fed from the card hopper. This mechanism includes a flat permanent magnetic strip mounted on the frame of the card hopper and a steel blade having one end pivotably mounted on the frame. The steel blade is magnetically attracted to the magnetic strip. The other end of the steel blade is attached to a pressure plate resting on the top card in the hopper. When a given number of cards are in the hopper, the steel blade is completely out of contact with the magnetic strip. At this time, the only weight applied to the drive roller is the weight of the cards plus the weight of the pressure plate. As cards are fed from the hopper, the steel blade is lowered into contact with the magnetic strip. The initial contact is adjacent the blade pivot point. As additional cards are fed, the contact area of the blade and spring increases incrementally in a rolling type manner such that the combination of the permanent magnet, steel blade, and pressure plate imparts an increasing downward pressure on the stack of cards to thereby off set the weight decrease resulting from the feeding of cards to provide a fairly uniform weight on the card drive roller which varies within acceptable limits such that reliable card feeding of all the cards in the hopper is accomplished.

Patent ES-432174-A1 (ES)
Title: Integrity indicator
IPC: A61L2/28
Filed: 1974-11-22
Abstract: A system for indicating the integrity of a normally sealed package utilizes a sensor containing a pH sensitive dye which displays a first color in equilibrium with normal atmospheric conditions and a second color when in equilibrium with an artificial atmosphere comprising an acidic gaseous material. When the air normally in the package is displaced by the artificial atmosphere, the pH sensitive dye assumes its second color. Loss of integrity of the sealed package results in loss of the acidic gaseous material. As a consequence, the pH sensitive dye reverts to its first color, thereby signaling the loss of package integrity.

Title: Driven plates for friction clutches
IPC: F16D13/60
Filed: 1975-12-30
Abstract: This invention relates to clutch driven plates having an annular component which carries the friction facings and which is mounted for limited rotary movement on a hub so that it extends between a pair of radially extending discs which are fixed to the hub by engagement of serrations formed at their inner peripheral edges in grooves in the hub. The hub has three spaced annular rims which co-operate to form two spaced annular grooves. The two outer rims taper outwardly and the central rim, which is cylindrical, locates a cylindrical spacer which spaces the disc apart. The grooves which receive the serrations are formed in the outer rims. During assembly of the clutch driven plate, the discs are forced axially on to the hub. The grooves are cut by the serrations during assembly and the material that is cut from each rim of the hub by the formation of the grooves is directed into the adjacent annular groove. Once the disc are located against the spacer, the hub is deformed to retain the discs on the hub.

Title: Manufacture of solid ammonium phosphate
IPC: C01B25/28
Filed: 1976-01-30
Abstract: The invention relates to a process for the manufacture of solid monammonium phosphate in a suitable form for use as an ingredient in the granulation of NPK compound fertilizers.
