Title: Adjustable friction clutch for presses
IPC: F16D13/62
Filed: 1977-11-04
Abstract: A friction clutch assembly, for a press and especially a screw press, includes: a pair of rotating, coaxial, annular, spaced drive members, at least one of which is axially movable toward and away from the other an off-drive shaft disposed coaxially with the drive members a spring plate centrally clamped to the off-drive shaft and extending radially on both sides of the shaft to terminate in outer segments, carrying friction coatings, disposed in the space between the drive members, so that, upon movement of one of the drive members toward the other to actuate, or close, the clutch, the friction coatings are clamped between the drive members, elastically deforming the spring plate to adjust to the reduced spacing and to transmit the requisite high torque through the spring plate required to turn the off-drive shaft. Particularly valuable and novel features of the clutch construction are the friction coatings, so arranged on the spring plate that their inside edges, facing toward the off-drive shaft, extend along straight lines perpendicular to a radius starting from the shaft, and means (for clamping the spring plate to the off-drive shaft which have outer edges), also terminating in straight lines parallel to the inside edges of the friction coatings, so that the bending forces applied to the spring plate are along straight lines and in the same direction, thus causing uniform bending of the spring plate and preventing spherical deformations normally obtained with annular drive members and disc-shaped spring plates.
Patent ES-463949-A1 (ES)
Title: Voltage surge protector
IPC: H01T1/14
Filed: 1977-11-08
Abstract: Electrical equipment, such as telephone station apparatus, exposed to occasional, destructively high, voltage surges (e.g., lightning strikes), is protected by a device placed in parallel with the equipment, including two metal electrodes and an insulating housing. The electrodes define a fixed narrow spark gap which breaks down (arcs over) to short the voltage surge to ground. The width of the spark gap is critical, since it determines the protective breakdown voltage. In the disclosed devices the gap is closely defined although tolerances on the piece parts from which the device is made may be loose. At least one electrode consists of a flanged support member soldered to an electrode cap. The piece parts are assembled with the electrode faces in contact and raised to the soldering temperature. The gap forms as the temperature is reduced from the liquidus temperature of the soldering alloy to ambient temperature because of differential contraction between the insulator material and the metal parts.

Patent ES-469010-A1 (ES)
Title: Torsional oscillation alarm system
IPC: G01H1/10
Filed: 1978-04-20
Abstract: An alarm system is disclosed for generating alarms when torsional oscillations of a rotating shaft exceed predetermined limits and fail to subside at a predetermined rate. The alarm system receives a torsional oscillation input signal developed by measuring the deviation of instantaneous shaft angle from a uniformly increasing value. The input signal is converted to a direct current torsional oscillation signal representative of the magnitude of oscillation. The torsional oscillation signal is compared against a first adjustable reference voltage representative of a first maximum magnitude of oscillation. A low level alarm signal is generated when the oscillation signal exceeds the first reference voltage for a predetermined length of time. The oscillation signal is also compared against a second reference voltage representative of a second maximum magnitude of oscillation. An output signal is generated when the oscillation signal exceeds the second reference voltage. The output signal is then employed to activate a rate of decay circuit which generates a signal representative of the rate of decay of the oscillation signal. This representative rate of decay signal is compared against a third reference voltage representative of a minimum acceptable rate of decay. If the representative rate of decay signal exceeds the third adjustable reference voltage, a high level alarm signal is generated to indicate that the second maximum magnitude of oscillation has been exceeded and that the minimum required rate of decay has not been attained.

Title: Fuel injection nozzle
IPC: F02M61/10
Filed: 1979-04-30
Abstract: A fuel injection nozzle assembly for a diesel engine has the nozzle and the needle spring housing screwed together by a sleeve. As the fuel is injected from the pump tension stresses are set up in the body (12) in the region of the annular groove (24). This stress is minimised by shrinking on a ring (26) so that the body is in the free state, under a compressive stress. The ring forms the abutment for nozzle in the threaded sleeve holding the assembly together. Alternatively the ring could be of a wedge section that corresponds to a tapered face on the nozzle outside in the region of the groove, so that when the assembly is screwed together the ring wedges on the nozzle and exerts a compressive stress.
