Title: Twine retainer for knotter
IPC: A01F15/14
Filed: 1968-01-22
Abstract: A twine retainer 6 for use with a knotting mechanism 4 in a baling machine comprises a pair of discs 6A, 6B urged together by a compression spring 10 and a spring-loaded lever 11, the latter being cam controlled by a disc 2 driving the knotting mechanism such that the effect of the lever 11 on the discs 6A, 6B can be varied so that the twine is clamped tightly during the baling operation but only lightly during the knot tying operation. The lever 11 carries a follower running on the cam surface on the edge of the disc 2 such that it is urged to bear on the spring 10 and increase the load on the discs 6A, 6B during the baling operation. When the knotting operation is to be performed, the follower following the contour of the cam allows the lever 11 to release its effect on the spring 10. A certain effect is still maintained by the lever 11 on the spring 10 by a coil spring 17 bearing on the opposite end of the lever 11 and this effect can be adjusted for tensioning during knotting by a nut 18.

Patent ES-365912-A1 (ES)
Title: Power converter circuit operating as an electric potential transformer
IPC: H02M5/22
Filed: 1969-04-11
Abstract: In a power supply unit an h.f. transformer, e.g. with ferrite core, is used because of its small dimensions compared with a normal mains frequency one for the same power output. Thus voltage at the mains frequency is converted to a higher frequency, transformed (e.g. stepped up), converted back to the mains frequency and applied to a load. In Fig. 1a solid state switches 13, 15, 16, 17 are controlled by a unit 24 to conduct in pairs alternately the switching rate being at the higher frequency (e.g. range 1kHz to 50kHz). Thus 15, 17 conduct while 13, 16 are off and vice versa. The input and output switching circuits both function as inverters. Fig. 2 illustrates the waveforms which obtain when a 1 : 1 ratio transformer is used, the voltage applied to the load being seen to correspond in polarity phase and magnitude to the input voltage. The output voltage magnitude will of course depend upon the turns ratio of the tran - former used. The solid state switches may be bidirectional conducting devices such as diacs or triacs or each may be a pair of inverse-parallel connected SCR's or transistors or gate turn-off SCR's. Instead of the bi-phase switching arrangement shown, half bridge or full bridge arrangements may be used. Conventional gating and commutation circuits may be used and are not described. Overload protection.-When the load current is too high the switches 13, 15 are rendered non-conductive while 16, 17 are kept operating to dissipate reactive current, after which they turn off.

Patent ES-374513-A1 (ES)
Title: Automatic gas cutting device
IPC: B23K7/00
Filed: 1969-12-12
Abstract: A non-cutting condition during a flame cutting operation is detected by detecting a change in voltage between a torch 2 and the metal 4 being cut. A relay 8 is connected across the workpiece and torch mounted on a movable trolley 12, and is arranged to close when the voltage exceeds 0À8-0À9 volts. During a normal cutting operation the voltage across the workpiece and torch is 1À2-1À8 V. so that the relay 8 is closed and power is supplied through a cable 7 to the motor or clutch of the trolley 12. If a non-cutting condition arises, the volta ge across the workpiece and torch falls to 0-0À5 V. to cause the relay 8 to open and the trolley 12 to stop. The cutting oxygen supply is switched off preferably for a predetermined period to allow the workpiece 4 to be heated further so that when the cutting oxygen supply is resumed, the cut is restarted and the voltage is raised causing the trolley 12 to be moved again. If the voltage falls to zero indicating that the flame is no longer contacting the workpiece, both the oxygen and fuel gas supplies are automatically cut off. When the torch moves off the workpiece at the end of the cut, the voltage falls to cause the relay 8 to open and the trolley 12 to stop.

Patent ES-418199-A1 (ES)
Title: Gas-solids separator with access platform
IPC: B01D46/02
Filed: 1973-08-25
Abstract: A gas-solids separator generally known as a baghouse which employs elongated fabric filter elements mounted in a housing with each filter element flow connected to an opening in a tube sheet. Gas to be filtered enters the housing below the tube sheet and passes through the openings in the tube sheet and the filter elements. Particles of dust are collected on the filter elements and cleaned gas is exhausted from the area above the tube sheet. The filter elements are grouped to define walkways along the tube sheet to permit access to the lower portion of each of the filter elements. An elevated platform is mounted in the housing to permit access to the upper end of the filter elements. The horizontal width of the platform can be increased to permit its use by a maintenance man and decreased when the separator is filtering gas so that the filter bags do not contact the platform. This platform can be pivoted about its own longitudinal axis between a position which permits its use by a maintenance man and a position which prevents contact between the platform and the filter elements. A guard rail is provided on the platform.
