Patent ES-419612-A1 (ES)
Title: Rotor feed for an automatic firearm supplied by a single link hook and eye chain belt
IPC: F41A9/31
Filed: 1973-10-13
Abstract: The cartridge extraction post comprises a central star wheel rotor keyed on a longitudinal shaft whose axis is situated in the vertical plane of symmetry of the assembly of the feed at a level such that the star wheels project into the central upper zone of a transverse passage, formed of two opposite passages. The link-freed cartridges are removed by a pusher operating longitudinally passing through an opening formed in a central zone of the floor of the transverse passage. A fixed support cam in the central zone of the extraction station at the level passed by the back of the links is positioned over at least the fraction of the transverse passage in which the extraction of the cartridges occurs when the cartridge belt passes in the direction F2 reverse to the conventional direction F1 for which the hooks of the links are directed forwardly. The feed lends itself to routeing of the cartridge belt, either in the conventional direction F1 (hooks of the links directed forwardly) for which there is no risk of breakage of the belt by unhooking in the extraction phase, or in the reverse direction F2 (eyes of the links directed forwardly) the cam then resisting lifting and unhooking of the link in the extraction phase under the effect of the upward reaction then exerted on this link which continues to travel in the direction F2 under the action of the rotor thereby correctly driving the following link and the remainder of the belt.

Title: Detachable tooth for public works machine having a particular cotter
IPC: E02F9/28
Filed: 1973-10-15
Abstract: A detachable tooth such as for an excavating bucket, which tooth is coupled to a support by engagement of a head member and a socket member and is held in the engaged condition by a cotter extending through orifices in the head and socket members, the cotter comprising a main cotter which receives an auxiliary cotter slidable relative to the main cotter in a direction parallel with the direction of engagement of the head and socket members, the auxiliary cotter being biased away from the main cotter in that direction and including a lug to keep the cotter in position in the orifices. The main cotter normally bears on one of the socket and heat members and the auxiliary cotter on the other of those members, but bears on both to protect the biasing means between the main cotter and auxiliary cotter in the event of the auxiliary cotter being driven toward the main cotter by relative closing movement of the tooth toward the support.

Title: Manufacture of flat glass ribbons on a molten metal bath
IPC: C03B18/00
Filed: 1973-10-30
Abstract: Float glass of thickness in the range 5.5 mm to 8 mm is manufactured under high load conditions at the rate of 3,250 to 4,500 tonnes per week and is discharged from the molten metal bath at speed in the range of 380 to 600 meters per hour, without undue loss of width, by laterally confining the edges of the molten glass layer as it is poured on to the bath to impose initial acceleration on the glass. The glass in ribbon form which is later permitted unconfined lateral movement is already advancing at high speed and is attenuated to its desired thickness by further acceleration to the high discharge speed.

Patent ES-432250-A1 (ES)
Title: Anti-contaminant diaphragm valve
IPC: F16K31/40
Filed: 1974-11-25
Abstract: The solenoid plunger normally closes the center vent hole in the diaphragm so inlet pressure is applied through the bleed hole to the space above the diaphragm resulting in enough pressure to close the diaphragm on the valve seat. When the solenoid is actuated, the plunger is lifted, allowing water to flow through the vent faster than it can flow through the bleed hole. This lowers the pressure above the diaphragm so inlet pressure can move the diaphragm from the seat and full flow can take place. The bleed hole is quite small. To prevent entrained particles from reaching and plugging the bleed hole, an arcuate groove having a width less than the bleed hole diameter is molded into the diaphragm to trap particles in the groove and prevent the particles from reaching and closing the bleed hole.

Title: Comb filter employing a charge transfer device with plural mutually proportioned signal charge inputs
IPC: H03H15/02
Filed: 1979-08-01
Abstract: A comb filter comprising a charge transfer device (CTD) structure for separating frequency interleaved luminance and chrominance components of a composite color television signal directly within the CTD structure. The CTD structure has first and second pairs of input sections of substantially identical geometry, one input section of the second pair being preceded by a signal inverter.
