Patent ES-8308613-A1 (ES)
Title: Valve rotating device for an internal-combustion-engine valve
IPC: F01L1/32
Filed: 1982-12-15
Abstract: The device includes a circular array of rolling bodies (2) disposed in sloping pockets formed in a base member (3). An annular spring disc (1) normally presses the rolling bodies (2) fully down into their pockets. In use of the device, a valve spring so stresses the spring disc (1) during valve opening, as to result in the rolling bodies (2) being relieved of loading by the disc (1) under the urging of springs (8) housed in the pockets, these bodies (2) now move up to the shallower ends of the pockets. As the valve closes, the rolling bodies (2) are loaded again by the disc (1) and the resultant rolling of the bodies (2) down into their pockets causes the base member (3) to rotate relative to the spring disc (1). Further rolling elements (6) are interposed between the spring disc (1) and base member (3), intermediate the rolling bodies (2) and the zone of action (7) of the valve spring on the disc (1).
Patent ES-8404878-A1 (ES)
Title: Apparatus for recognizing, crushing separating, weighing and making payment for, used metal items, particularly aluminum cans
IPC: B07C5/36
Filed: 1983-06-08
Abstract: A housing has an input hopper for receiving municipal trash items, particularly aluminum cans, which drop onto a conveyor and are carried to a crusher. The crushed items drop onto a second conveyor which carries the items past a magnetic separator station which recognizes and separates out any ferrous materials. The remaining material, including aluminum cans, glass bottles, plastic cartons, paper and other items, are carried to an identification station which recognizes the aluminum items and signals a pusher mechanism to push the aluminum items off the conveyor. The pushed-off aluminum items drop into one of the pockets of a rotatable collector-and-wiper device. After a pre-selected number of items have been recognized and pushed off the conveyor, or if a time period of preselected length passes during which no additional items are received at the input hopper, a signal is generated which causes the collector-and-wiper device to be indexed, thereby to push the collector items onto the platform of a weighing scale. A signal is generated which is sent to a coin-payout mechanism to make payment for the weight of the aluminum items deposited on the scale.

Patent ES-8406829-A1 (ES)
Title: Ring-trip detector
IPC: H04M19/02
Filed: 1983-10-26
Abstract: A ring-trip detector circuit is disclosed which detects a subscriber off-hook condition in the presence of a ringing signal. The ring-trip detector employs substantially all low-voltage components which enables it to be fabricated using integrated circuit techniques with the resultant cost and space-saving advantages inherent therein. The ringing signal is disabled upon detection of a DC component which is present in the telephone loop only when the subscriber goes off-hook. This circuit detects the DC voltage component across a resistor (20) in series with the ringing source (19) and the telephone loop (12, 13). The voltage across this resistor (20) is converted by resistance networks (23, 24) into two relatively small currents that are fed to low impedance points (25, 26). A difference current is formed therebetween, which is filtered (31, 45) to remove AC components, and compared with a threshold current (29, 46). Ring-trip occurs when the filtered difference current exceeds the threshold.
Patent ES-8506378-A1 (ES)
Title: Fuel injection nozzles
IPC: F02M61/08
Filed: 1984-07-13
Abstract: A fuel injection nozzle for supplying fuel to an internal combustion engine is of the so-called outwardly opening type and has a valve head located in a pocket the wall of which is of right cylindrical form. A circumferential groove is formed in the wall of the pocket and fuel is communicated thereto by a further groove or grooves on the valve head. The valve head forms a first outlet communicating with the circumferential groove and through which on the initial lift of the valve head fuel flows to produce a low penetration fuel spray. As the head is further lifted ports in the valve head are exposed to the groove and these ports communicate with a central outlet in the head. A penetrative jet of fuel issues from the central outlet.
