Patent ES-465305-A1 (ES)
Title: Low weight reciprocating engine
IPC: F02F1/00
Filed: 1977-12-21
Abstract: An internal combustion V-8 engine is disclosed having an aluminum semi-permanent mold head cast by a low-pressure die-cast process and an iron block cast by the evaporative casting method. The block and head have controlled thickness walls throughout to optimally lower the metal/working volume ratio of the engine. The block employs barrel cylinder walls cast integrally and unsupported except at the barrel ends and at a siamese connection between adjacent barrels the barrels are maintained under a predetermined level of compression to eliminate fatigue failure and suppress sound. The block is sand cast and the head is totally formed with a three piece die and one sand core cluster, except for one passage which is drilled subsequent to casting. The engine is reduced in weight by at least 20% over conventional comparable engines torque and horsepower is improved even though the cooling system capacity has been reduced to less than half that of a conventional cooling system.
Patent ES-466348-A1 (ES)
Title: Security window
IPC: E05G7/00
Filed: 1978-01-26
Abstract: A security window has a non-transparent bullet resistant screen between the people on either side of the window. Because this screen cannot be seen through, an arrangement of mirrors (two on each side of the screen) is provided to reflect images from each side across to the other side. The customer and cashier each look into mirrors set at eye level on their respective sides of the screen and reflected images are directed to a point above the screen where two mirrors are arranged in a cavity. This cavity tends to act as a sounding box and permits sound to travel from one side of the screen to the other. The eye-level mirror on the cashier's side can be moved to a position where it merely reflects back the image reflected from the other side, in the event of an attack.

Patent ES-476304-A1 (ES)
Title: Apparatus for removing closures from containers assembled in cases
IPC: B67B7/18
Filed: 1978-12-22
Abstract: In apparatus for removing closures from containers that are assembled in cases which are moved seriatim into position below multiple spindles arranged with respect to the container positions in the cases, each spindle 32 has a non-rotatable internally threaded nut 56 with a freely rotatable externally threaded screw 58 therethrough, and a head unit 42 for gripping a closure on the container. Axial displacement of the multiple spindles with respect to the containers causes the head unit of each spindle to grip by means of jaws 64 a container by its closure, if it has one thereon. Axial displacement of the screw with respect to the nut rotates the screw with sufficient torque to break any bond or seal securing the closure without need of holding the container to prevent its rotation.
Patent ES-8101496-A1 (ES)
Title: Windings arrangements
IPC: B66D1/74
Filed: 1979-04-11
Abstract: A winding arrangement suitable for sheeting in a sail of a yacht comprises a winch drum (2), a handle (6) for rotating the winch drum, coupling means (30) operable in a first mode to connect a hydraulic pump/motor (15) to the handle to act as a pump driven by the handle, and operable in a second mode to connect the hydraulic pump/motor to the winch drum to act as a motor driving the drum, and control means (40, 41, 61) for changing the coupling means from the first mode to the second mode and vice versa. It is therefore possible, by operating this winding arrangement in the first mode, to rotate the winch drum manually so as to wind in a sail sheet or line attached to the winch drum, and at the same time to drive the pump to charge up a hydraulic accumulator (28) or pass hydraulic fluid to another similar winding arrangement operating in the second mode either directly or through a hydraulic intensifier (33). When the coupling means is operable in the second mode one or more similar winding arrangements may supply hydraulic fluid to the pump/motor either directly or through the hydraulic intensifier (33).
Patent ES-489336-A1 (ES)
Title: Imbalance-oscillation exciter
IPC: B06B1/16
Filed: 1980-03-07
Abstract: An imbalance oscillation exciter having two imbalance weights arranged on each of two axially parallel or coaxial imbalance-weight carriers positively rotatably coupled with one another and rotating counter to each other or in the same direction. At least one of these imbalance-weight carriers comprises a shaft, whereby the imbalance-weight carriers are coupled with each other by a hub for continuous opposite rotation for the purpose of changing the phase position of the imbalance weights. A pin fixed on the shaft slidably engages in a hub groove. The pin is shiftable along a shaft slot extending at an incline to the hub groove by means of an adjustment member arranged coaxially in the shaft. The shaft has an axially parallel cylinder chamber open toward one of its end faces and in which the adjustment member is slidable with a piston extension sealed with respect thereto and facing the open side of the cylinder chamber. Pressure medium is supplied from the open side by way of a pressure medium chamber fixed in the housing and sealingly surrounding the pertaining shaft end and being applied against the mechanical back or reaction pressure of the piston extension. The rise or angle of inclination between the hub groove and the shaft slot, the direction of inclination, and the direction of rotation of the shaft may be so matched or adapted with respect to each other that the back or reaction pressure results from the torque transmitted by the pin.

Patent ES-8104934-A1 (ES)
Title: Safety assembly for a tool for driving fasteners
IPC: B25C1/04
Filed: 1980-05-12
Abstract: A tool for driving fasteners includes a driver and a device for actuating the driver through a driving stroke. The tool is operated by a trigger assembly that includes a manually actuated trigger pivotally mounted on the tool and a lever pivotally mounted at a first end to the trigger. Also included on the tool is a safety assembly that before the tool can be fired must be actuated prior to actuation of the trigger. The safety mechanism includes a push rod slideably mounted within the tool with a first end engaging a safety yoke and a second end adjacent the lever of the trigger assembly. The safety yoke is slideably mounted on the nose of the tool and is adapted to extend below the nose of the tool to engage the workpiece upon placement of the tool onto the workpiece. As the tool is placed against a workpiece prior to actuation of the trigger, the yoke and, thus, the push rod are moved upwardly until the second end of the push rod engages the lever placing the trigger assembly in an operative mode. As the trigger is thereafter actuated, the lever is pivoted to actuate the tool and drive a fastener. The safety assembly includes an engagement or locking element on the second end of the rod that locks the second end of the lever in an inoperative position if the trigger is actuated prior to the placement of the tool onto the workpiece.

Patent ES-8400235-A1 (ES)
Title: Electrosurgical generator safety apparatus
IPC: H02H9/02
Filed: 1982-07-20
Abstract: Leakage cancelling apparatus suitable for use in electrosurgery apparatus to prevent electrical burns is disclosed. The apparatus comprises a transformer which is connected in the electrical circuit between the electrosurgical source and the patient. The transformer has a primary winding connected in series with the active surgical electrode and a secondary winding connected in series with the return path to the electrosurgical generator. The connections to the windings are polarized so that during normal operation the magnetic fields in the transformer core generated by current flow are almost completely cancelled. Consequently, the transformer windings present very small impedances in series with the electrosurgical circuit. If a break occurs in the return lead of the electrosurgical circuit and the patient becomes ungrounded, a condition which would normally result in a high risk of a burn, the currents in the primary and secondary windings of the transformer become unequal, the magnetic fields in the transformer core do not cancel and the transformer windings present a significant impedance to the flow of electrosurgical current which reduces the occurence of electrosurgical burns. In addition, the uncanceled inductance presented by the transformer windings during a break situation may be chosen to resonate with the leakage capacitance of the electrosurgical circuit, further reducing the current flow and preventing burns.
