Patent ES-8504960-A1 (ES)
Title: Method for producing blister copper
IPC: C22B15/00
Filed: 1984-03-02
Abstract: The invention relates to a method for producing blister copper from copper-iron sulphide concentrates, and particularly from concentrates whose sulphur content is insufficient to effect autogenous smelting of the concentrates to matte. The invention is characterized in that the concentrate, together with slag former, is smelted with oxygen-gas or air rich in oxygen in a top blown rotary converter, to form a mixture of a contaminated copper metal phase, magnetite and fayalite slag, whereafter a reductant, preferably coke, is supplied for the reduction of magnetite while supplying heat. After the reduction process, the slag is separated from the formed copper metal phase, which is then refined to blister copper in a manner known per se. In this respect, a preferred method of refining the copper metal phase, or black copper, is to refine the black copper, subsequent to separating the slag, in the converter by an oxidizing process with the addition of a further slag former, to form blister copper and a slag containing oxidized impurities from the ingoing copper metal phase.

Title: Formation of element-free spaces in slide fastener chains.
IPC: A44B19/58
Filed: 1984-06-27
Abstract: A punch blade (72 80) depresses the coupling heads (79) of a length of successive filamentary coupling elements (76) toward a knockout blade (39) while sandwiching stringer tapes (43, 44) between upper and lower grippers (55, 56, 21, 22). The punch blade (72 80) is lowered until lower legs (78) of the coupling elements (76) are cut off by cutter blades (31, 32). The punch blade (72 80) and the knockout blade (39) are then lifted while gripping the severed coupling elements (76) therebetween to forcibly remove the coupling elements (76) out of engagement with sewing thereads (77) on the stringer tapes (43, 44). The upper grippers (55, 56) have confronting steps (61, 62) for engaging the sewing threads (77) so that the severed coupling elements (76) can be detached reliably and smoothly from the stringer tgapes (43, 44) without unduly tensioning the sewing threads (77) and stringer tapes (43, 44). The punch blade (80) may have a vertical reinforcement member attached to at least one side edge thereof and having a lower tooth (86) projecting downwardly beyond a lower edge (84) is pressed against the coupling elements (76), the lower tooth (86) enters between adjacent coupling elements (76) to position the coupling elements (76) against unwanted longitudinal displacement with respect to the punch blade (80).

Patent ES-8604403-A1 (ES)
Title: Guidance control system for a row crop harvester.
IPC: A01D41/127
Filed: 1984-09-05
Abstract: A forage harvester (11), pulled via its tongue (16) by a tractor, has dividers (19, 21) between which a crop row (18) is received, and each divider has a row sensing unit (41, 43) of a guidance control system bolted to it. The crop row passes between a pair of arms (47, 48) of the units. An arm is deflected, when the machine is misaligned with the row, the arm having an upright pivot shaft (79). Each arm carries an actuator plate (95) which closes a corresponding sensing switch (145, 147) to trigger a guidance control circuit (45) to steer the harvester by way of a piston and cylinder (33) moving the tongue to return the harvester to alignment with the crop row. These first and second switches are connected to an electrically responsive control valve arrangement (185) which controls the cylinder. To avoid the two sensing switches (145, 147) sending contradictory signals simultaneously to the control valve arrangement (185), first and second relays (201, 203) are connected between the respective switches and the control valve arrangement, and the first and second switches are also connected to the relay coils of the second and first relays respectively. This causes the first switch (145), when closed, to open the second relay (203), and the second switch (147), when closed, to open the first relay (201).

Title: Multi-segment, non-flexible boot for mechanical joint
IPC: F16D3/224
Filed: 1986-02-14
Abstract: A sealing boot for sealing a power transmitting mechanical joint, especially a mechanical joint which is subject to angular articulation between its input shaft and output shaft. The mechanical joint has an outer race which is a part of its output shaft, and the outer race has an external spherical surface. The sealing boot has a non-flexible portion which surrounds a portion of the outer race, and this non-flexible portion has a spherical inner surface which sealingly engages the external spherical sealing surface of the outer race in surface-to-surface contact. The non-flexible portion of the boot and the outer race of the joint can be articulated relative to one another without breaking the seal therebetween. In the preferred embodiment the remainder of the boot constitutes a non-pleated non-flexible second boot segment, one end of which is received in a spherical slot of the first non-flexible portion and the other end of which sealingly engages the input shaft of the mechanical joint. A portion of the articulation required of the power transmitting mechanical joint is obtained by the movement of the second boot segment in the spherical slot of the spherical boot segment. Additional articulation is provided by the spherical sliding of the spherical boot segment on the spherical surface of the outer race after the second boot segment bottoms in the spherical slot of the spherical boot segment.
