Patent ES-338705-A1 (ES)
Title: Sealing device for the connecting point between feeding member and tool in extrusion presses
IPC: B29C48/05
Filed: 1967-03-31
Abstract: A melt-spinning apparatus comprises a cylindrical spinning pack housing 11 (Fig. 1) provided with a closure in the form of a piston 10 having an axial passageway 13 for the melt and a feed member 1 which is part of the main spinning apparatus and is provided with a melt inlet channel 2 coaxial with the passageway 13. Integral with the feed member 1 is a support member 3 for the housing 11. The member 3 is provided with an opening 4 for the filaments extruded through the orifices 8 in the spinneret plate 7 and with two guide rails 5. The underside of the feed member 1 has a sloping surface at 6. Between the bottom of the piston 10 and the feed side spinneret 7 contained in the housing 11 is positioned a metal annular spring diaphragm 9 the edge portion of the lower surface of which is soldered or welded to the rim of the inlet face of the spinneret 7 and the central position of the upper surface of which is welded or soldered to the raised portion of the undersurface of the piston 10 surrounding the outlet of the duct 13 in the piston. Before the housing 11 containing the spinning pack is inserted in the spinning head 3 the diaphragm is in an unflexed state. When the housing 11 is inserted into the space or recess between the parts 1 and 3 of the spinning head between the parallel guide rails 5, a sealing element 12 located at the top of the piston 10 slides along the sloping portion 6 of the undersurface of the member 1 until the feed duct 2 and piston bore 13 are in alignment. When the spinning pack is in this operative position, the diaphragm 9 is flexed downwards and acts as a spring urging the seal 12 against the portion of the underside of the feed member 1 surrounding the inlet duct 2. This portion of the underside is parallel to the upper surface of the element 12, the two surfaces function as the faces of a joint between the feed member and the piston or closure member of the spinning pack. In the modification shown in Fig. 2 the piston 10 is urged towards the seal 12 by an annular disc 15 of deformable resilient material which functions as a plate spring. The chamber between the inlet face of the spinneret plate 7 and the underside of the piston 10 is sealed by sealing rings or gaskets 16 and 17 of resilient material. The sealing effect of the two rings increases as the pressure of the melt rises.

Title: Connector means and methods for relatively soft conductors
IPC: H01R4/00
Filed: 1967-06-19
Abstract: As shown in Fig. 3, a device for connecting sheathed cables having cores of a plastic material, e.g. sodium and its alloys, comprises an insulating housing 16 of two mating halves 18, 20 formed with cable receiving cavities and aligned bores 39, 40. A cutting device comprising a cylindrical can 38 having a bevelled cutting edge is drawn through the bores 40, 39 by turning a nut 36, cutting away and retaining in the can a part of the sheath J and core C of each cable, leaving a common void, with the closed end of the can 38 closing bore 39 and a sealing plate 48 closing the enlarged portion 41 of bore 40. A plug (50, Fig. 2, not shown) is screwed into the free end of the tap off cable (14) to extrude core material into the common void, to connect the cable cores electrically. The extrusion rate may be increased by applying a further force between the plug and the void. The mating surfaces, projections and recesses of the housing halves may be coated with a quick setting adhesive or cement. In another embodiment (Fig. 6, not shown) overlapping ends of parallel cables (58, 59) are joined, core material being extruded into the common void by a plug (72) in the free end of each cable, both ends being contained within the housing (62). In a further embodiment (Fig. 7, not shown) the cables are at right angles to each other in different planes, and the housing may be enlarged (Fig. 8, not shown) to accommodate three tap off cables. Cutting members of other configurations may be used.

Title: Trans-lift section conveyor
IPC: B65G47/00
Filed: 1969-11-21
Abstract: Loads to be transferred from a roller conveyer 14 to shelves 2 of a vertically movable elevator are moved on to rollerways 16, 18 of a carriage which is guided by channels 26, 28. Ramps 30, 32 cause the carriage to be raised when it is moved towards the shelf 2 by a fluid pistoncylinder unit 62, 64. A load, having been transferred from the conveyer 14 to fixed rollerways 8, 10 is then raised by the carriage, as the latter moves to the left, until the tops of rollers 42, 44 provided on the carriage, are level with rollers 9, 11 on the shelf 2. The rollers 42, 44 are then driven to move the load on to the rollers 9, 11. Fluid motors, via chain and sprocket drive, energize the conveyer 14, the rollerways 8, 10 and the rollers 42, 44 of the carriage. The fluid system is manually controlled but automatic control is possible. Close alignment of the shelves 2 and the loading station is unnecessary but if the levels between the rollers 42, 44 and 9, 11 differ by an amount greater than the height of the ramps 30, 32, the shelf at the station must be more closely aligned with the rollers 42, 44. The apparatus may be used for transferring a load from the elevator to the conveyer 14.

Title: Vibratory impact hammer
IPC: E02F9/00
Filed: 1974-06-11
Abstract: An impact force producing apparatus that is described in connection with one particularly suitable use on a backhoe vehicle although it is usable on other vehicles and apparatus. A frame is provided which can be attached directly to the backhoe. A heavy ram is flexibly mounted to the frame in such a manner that it may freely oscillate relative to the frame. Attached to the ram is a hydraulic motor coupled with an eccentric weight to provoke vibrational movement in the ram. The relative inertias and locations of the components, the resilient mountings and the driving force of the eccentric weight are interrelated to create a vibratory motion in the ram which provides a unidirectional impact on a tool positioned on the frame and drives the ram near a resonance of the system. Guides may be provided to eliminate secondary harmonics and extraneous vibrations and movements.

Title: Noise and cross-talk elimination in recording and reproducing video signals
IPC: H04N5/923
Filed: 1977-07-05
Abstract: In apparatus for recording and reproducing video signals in successive parallel tracks of reduced width and without guard bands therebetween so as to achieve a high recording density on the magnetic tape or other record medium, and in which a high frequency portion of the video signals, for example, the luminance component of color video signals, is frequency modulated for the recording thereof, processing circuits are operative in the recording and reproducing modes of operation to act on the luminance component prior to its frequency modulation in recording and after its demodulation in reproducing, respectively, for substantially eliminating from the demodulated luminance component the usual FM noise signal and also any interfering signal due to cross-talk, for example, as results from a lack of H-alignment between the signals recorded in adjacent tracks when the apparatus is intended to be operated with two different tape speeds. Such processing circuits provide non-linear pre-emphasis and substantially complementary non-linear de-emphasis in recording and reproducing, respectively, with the amounts of pre-emphasis and de-emphasis being dependent on the level and frequency of the signal being recorded and reproduced and preferably also dependent on the level-frequency characteristic of the interfering signal due to cross-talk appearing on reproduction.
