Patent ES-466543-A1 (ES)
Title: Leakage reactance transformer
IPC: H01F38/08
Filed: 1978-02-01
Abstract: This specification discloses a leakage reactance transformer for supplying electric arc welding current and comprising a core formed from a stack of laminations having a central 'key-hole' shaped opening punched therein and defining an arcuate core portion and two spaced legs. The core has primary and secondary windings mounted thereon and a keeper secured to the legs to close the flux path of the core. One of the windings is mounted on a frame which is pivoted relative to the core so that the winding is movable along the arcuate core section towards and away from the other winding. A magnetic shunt member is also mounted on the frame approximately 180 DEG from the movable winding and in one position bridges the gap between the legs of the core and in another position is remote from this gap. In the bridging position the shunt contributes to the leakage reactance of the transformer and in the remote position contributes substantially no leakage reactance. The shunt is formed from a sector of the portion of the laminations cut from the core to define the arcuate section of the opening and the keeper is formed from the remainder of the portion cut from the core and defining the space between the legs of the core. The core and windings are mounted within a casing and means are provided to facilitate the pivotal movement of the movable winding and shunt to any position between the two extremes whereby the welding current may be infinitely varied between the values at the extremes.

Title: Mineral mining installation
IPC: E21C25/60
Filed: 1978-12-07
Abstract: A mineral mining installation comprises a mechanical mining machine (such as a plough or a shearer) and a hydraulic winning machine.

Means are provided for driving each of the two winning machines independently of the other along a mineral face. This permits the mechanical winning machine to operate at its optimum, high speed rate without interference from the slower moving hydraulic winning machine. The pump is preferably a multiple radial-piston pump powered by an electric motor. Both electric power and water may be supplied to the hydraulic winning machine via pick-up arms on the machine and supply channels extending along the face.

Title: Method and device for shirring tubular casings.
IPC: A22C13/02
Filed: 1984-06-12
Abstract: Disclosed is a process for shirring tubular casings, in particular sausage casings, in which the casing is conveyed in the direction of its longitudinal axis and shirred against a counterforce by means of a shirring tool. The shirred tubing portion is divided into individual shirred sticks of a predetermined length and, if appropriate, the cut-off shirred sticks are further compressed. While being shirred and in the shirred state the casing is internally supported. For cutting-off a shirred tubing portion, the transport of the casing in the direction of its longitudinal axis is momentarily interrupted, the internal support is withdrawn from the severing region, and the unshirred or deshirred tubing section is severed at the rear aperture of the shirring tool. During severing, the not-yet-shirred casing surrounded by the shirring tool is permanently internally supported. The apparatus for performing the process comprises a shirring mandrel composed of two mandrel members disposed within the tubular casing which, during the transport of the casing, are brought into flush contact. The second mandrel member, seen in the direction of shirring, may be exchanged for at least one further mandrel member.
