Patent ES-480834-A1 (ES)
Title: Formed coil assembly
IPC: F25B39/00
Filed: 1979-05-23
Abstract: Apparatus and a method of manufacturing a formed coil having multiple single row coil cores of varying lengths. Sheets of fins are cut from plate fin stock such that the fins within each sheet are connected to each other by rupturable tabular portions. The sheets of fins are then arranged in registration such that openings within the fins for the receipt of tubes are aligned and tubular members or hairpins may be inserted within the fins to form part of the fluid flow circuit of the coil. Since the hairpins for adjacent coil rows are of different lengths, when the multiple row coil core is bent each coil row is formed about a separate radius curvature so that the formed coil will be in the desired configuration. Prior to bending, the hairpins are expanded to form a heat transfer bond with the fins, the expansion process acting to rupture the tabular portions connecting the fins such that the fins on the hairpins become separately spaced along each hairpin. Thereafter the coil core is bent to the desired formed coil configuration wherein the fins are spaced distinctly along each coil row notwithstanding that the fins were originally from the same sheet and connected to each other by the tabular portions.

Patent ES-8400666-A1 (ES)
Title: Electrosurgical generator
IPC: H02M7/537
Filed: 1982-07-20
Abstract: A solid-state electrosurgical generator is disclosed which provides three separate output circuits that may be operated from a single common power source. One of the output circuits produces an output electrical waveform which is optimized for cutting and coagulation with monopolar electrodes. Another circuit provides a waveform which is optimized for cutting and coagulation with bipolar electrodes. The other electrosurgical circuit produces an output electrical waveform which is optimized for fulguration. The output circuits produce the optimized waveforms by appropriately processing electrical power provided by a D.C. power source. In order to do this, the output circuits may be connected to the power source by means of four semiconductor switches may be arranged in either a bridge configuration for one output circuit or in a series arrangement for the other output circuit. The switches are, in turn, controlled by a timing circuit which provides different timing waveforms to the switches depending on their configuration.
Patent ES-8400560-A1 (ES)
Title: Rolling key clutch
IPC: F16D11/06
Filed: 1982-09-14
Abstract: The invention provides for an additional finger (5) engageable with a driver (7) of the rolling key (29), said finger (5) being located on an angularly movable bush (1). There is also provided a bearing ring (10) which is provided with a recess segment (17-18) into which the driver (7) extends. When said clutch actuating mechanism is disengaged with the drive motor at a standstill, the driver (7) takes up a position under spring-loading in which it bears against one edge (17) of said recess segment and sets the rolling key in its coupling position. Subsequent energisation of the drive motor will then only drive the shaft and the rolling key until the rolling key driver (7) comes to rest against the additional finger (5) of the bush (1). The rolling key is then turned back into its released position, without movement on the part of the machine. In that manner, accidents and breakdowns within the tooling area as referred to, are also avoided in the event of unauthorised actuation of the engagement/release arrangement.

Title: Device for the detection of gear changing for a clutch control system linked to a gearbox.
IPC: F16H59/02
Filed: 1986-01-08
Abstract: A device detects forces in a gearbox operating linkage in order to control an automatic clutch operating system for the purpose of changing the gear ratio. The linkage comprises a shaft in the gearbox adapted to rotate between two limiting positions corresponding to selection of respective different gear ratios. It also comprises a deformable linkage element in the force detecting device adapted to move between two limiting positions corresponding to the limiting positions of the shaft. This deformable linkage element comprises two portions coupled together elastically by an elastic return device. The force detecting device comprises a speed parity detector adapted to assume a parity state representing the position of the shaft and varying according to which of its limiting positions the shaft is in. It also comprises a force direction detector associated with the deformable linkage element adapted to assume a state representing the configuration of this element, which varies according to whether the element is loaded in one or the other of two reference directions. These reference directions respectively correspond to movement of the deformable linkage element from one to the other of its limiting positions and vice-versa. The parity detector and force direction detector are connected to a processor circuit adapted to activate the automatic clutch operating system to disengage the clutch when the deformable linkage element is loaded in a direction tending to move the shaft to an unoccupied limiting position.
