Title: Metal extrusion press of turntable type
IPC: B21C23/21
Filed: 1968-02-14
Abstract: A metal extrusion press has a series of containers 39a, 39b, 39c mounted on aturntable 32 which moves them successively to a cleaning and residue removing station B, billet loading station C and extruding station A. The extruding ram 7 is mounted on a crosshead 5 and driven by a cylinder assembly 2 connected by tie rods 3 to a backing frame 1. The ram 7 may be hollow so that a mandrel 21a, 21b can be passed through when the press is used to extrude tubes. The mandrels are mounted in a carrier 12 which is eccentrically journalled in the assembly 2 so that one mandrel is allowed to cool every alternate cycle. The extruding dies 29a, (29b), Fig. 2 (not shown), are mounted on a plate 23 which is intermittently rotated by an electric motor 26 to align one of the dies with the extrusion axis. A saw (31a) is advanced by a piston-cylinder assembly (31) to cut the extruded stock from the residue. The containers 39a, 39b, 39c are each mounted in a holder 37, 38 which has a cylinder 40 to move the container axially against the die before the extrusion. A roller conveyer 43 is fixed to the frame 1 and co-operates with roller conveyers 42a, 42b, 42c to support the extruded work. At station B the residue is removed by a plunger plate 47 and the walls of the container cleaned by brushes 47a. The container holders may be rotated during the cleaning and aligned parallel to the extrusion axis. After each extrusion the turntable is indexed 120 degrees so that the cleaned container can be loaded with a billet 53 and a pusher disc 54 at station C. The billet may be hollow and the disc annular when tubes are being extruded. At station A, after extrusion the residue is frictionally held in the container and retraction of the container 39a pulls the die 29a from the plate and the die is ejected from the press with the residue and the pusher disc 54. Alternatively the residue may be removed by the ram 7 and the station B used solely to clean the container. The turntable is preferably horizontal although it may be slightly inclined. Further the container may be cleaned and loaded at one station from opposite sides. In an alternate embodiment, Figs. 5 and 6 (not shown), five containers (66a), (66b), (66c), (66d), (66e), are secured to the turntable (60) and four preparatory stations (B), (C), (D), (E) arranged around the turntable. Stations (B), (C) remove the residue and clean the containers respectively and stations (D), (E) load the container and pierce the billet respectively. The container holders are pivoted by rack and pinion (64), (64a) to turn the container to the vertical at station (D) so that the billet can be loaded by a carrier (79). A piercing press (82), Fig. 6 (not shown), is provided at station (E) and has a stem (83) with a mandrel (84) and a back-up bar (85) for the container. A stem (86) is provided in the bar (85) to close the base of the container.

Title: Process and apparatus for melt spinning thermoplastic yarn
IPC: D01D5/08
Filed: 1968-12-04
Abstract: Melt-spun fibres and filaments are made by extruding a plurality of molten synthetic polymer filaments from a multi-orifice, preferably circular, spinneret assembly downwardly into a cooling gaseous medium, preferably directed radially inwardly and horizontally across the filaments over an arc of about 180 degrees, thus substantially solidifying the filaments directing a cushion of a steady current of a gaseous medium against the substantially solidified filaments, the current emanating from a relatively narrow source positioned in the filaments' path, substantially perpendicular thereto, and having sufficient force to prevent contact of the filaments with the current source and forwarding the filaments, the path of which may change direction at the gaseous cushion. At least one other cushion of gas may be directed against the filaments at a position no farther upstream of the filament path than the first-mentioned gaseous cushion. The front wall of the preferred enclosure for the cooling gaseous medium, which has inlet means for a supply of the cooling gas, has a longitudinally concave foraminous surface extending into the enclosure, the other walls having edges substantially coextensive with the concave surface, whereby the gaseous cooling means co-operates with the spinneret assembly and partially surrounds the extruded molten filaments. Filament steadying means are provided which may comprise a closed tube having means to receive pressurized gas, preferably a straight metallic tube closed at one end and adapted to receive pressurized gas at the other end, at least a portion of which comprises a microporous section from which the cushion of gas emanates. Figs. 1, 2 and 3 (2 and 3 not shown) show schematic side views of three embodiments of the invention, Fig. 4 (not shown) shows quenching apparatus and Figs. 5 and 6 (Fig. 6, not shown) show two suitable gas cushion supply means.

Title: Gas treatment process
IPC: C10K1/14
Filed: 1969-02-21
Abstract: Acid gases, especially CO 2 and H 2 S, are removed from gas streams, e.g. of hydrogen or synthesis gas, by passing the stream, together with some of the rich solvent which leaves absorber 3 by line 5, through reaction-heat cooler 2, and thence to absorber 3 where it rises in counter-current to lean monoethanolamine absorbent which is sprayed into absorber 3 through line 4, the purified gas stream leaving by line 6. The rest of the rich solvent from absorber 3 passes by line 7 to multistage flash tower 9, the solvent from each stage passing through exchangers 10-13 in turn before entering the next stage. CO 2 is vented at 17. The lean amine from the base of the tower 9 passes by line 14 to recovery tower 16 equipped with reboilers 18, 19, where residual CO 2 , is driven off and vented through line 25. Lean amine leaves by line 20, and part is returned as heat exchange medium for heat exchangers 10-13 before passing back to absorber 3 through line 4.

Title: A device for tuning a radio or television receiver
IPC: H03J1/06
Filed: 1969-05-08
Abstract: A device for tuning a radio or television by capacitance diodes and potentiometers comprises a plurality of push-buttons 1, each axially displaceable for switching into a tuned circuit the associated potentiometer 41, a nut 47, 49 supporting the potentiometer tapping contact 51, one of a further nut 25, 27 or screw-threaded bolt 21 coupled for rotation with the button and being axially displaceable with the button to drive a station indicator 35, common to all buttons, such that when the nuts are moved to contact stops the nuts can jump back by one turn of its associated screw thread substantially simultaneously. This enables the station indicator to remain correctly adjusted for the setting of the associated potetiometer if the push-button is rotated beyond the end stops. When the button 1 is pressed in it releases any previously pressed button. The slider 51 and station indicator 35 can then be adjusted by rotation of the pressed button 1 via gearing 15, 19 and 17. The gears 17 and 19 may be metal or synthetic material and gear 15 may be synthetic resin. The nuts 25, 27 and 47, 49 have U-shaped springs 25, 49 which enable them to jump back one turn of their associated thread together if the button 1 is rotated beyond the end stop position where the nuts 25, 27 and 47, 49 contact end stops 29 or 17 and one end wall of the potentiometer synthetic resin casing 43. Alternatively the rotatable screw-threaded bolt 21 may be attached to the free end of rod 3 so as to cooperate with the non-rotatable nut acting to drive the station indicator. In a further modification a bolt can be made non-rotatable to the head 23 with the nut rotatably coupled to gear wheel 15 so that the nut acts to move the station indicator. The axially displaceable member 9 can be of plastics and the potentiometer may have a resistive layer 45 such as carbon. The station indicator U-shaped bracket 35 is spring-biased towards gear 17 and may be coupled to a pointer or drum.

Title: High speed cross winding apparatus
IPC: B65H54/28
Filed: 1969-10-24
Abstract: A yarn traversing mechanism comprises a first traversing device in the form of a reciprocable thread guide, and a second traversing device in the form of a rotatable thread guide which is arranged exclusively in the region of the two ends of the traverse, stroke, the first and second traverse motion devices being driven synchronously with each other but independently of the package. In Fig. 2 the first traversing device comprises a reciprocable thread guide 16 traversed by a threaded roller 1 and just before the guide 16 reaches the end of its traverse the yarn is caught up by an end 39 of a thread guide groove 6, 7 of a second traversing device 4, 5 and is temporarily removed from the guide 16 whilst it is reversed. By the time the second traversing device 4, 5 returns the yarn to the roller 1 the guide 16 is once again in a position to receive the yarn. In this embodiment the second traversing means 4, 5 are co-axial with the thread roller 1 and each includes a slot which has an increased angle of inclination 11 in the region just after its reversal point 10. The guide 16 slides between fixed guide rails 18. The thread roller 1 and the second traversing means 4, 5 are mounted on a common shaft 12. The package may be driven by a separately mounted drum (8) Fig. 1 (not shown). In Fig. 3 (not shown) the traverse means 4, 5 are mounted on a drive shaft (25) arranged with its axis parallel to that of the roller 1. In Fig. 6 the first traverse means is a threaded roller 1 in which a thread guide 16 slides. The second traverse motion comprises thread guide means 28, 29 in which thread guide grooves 30 and 31 are cut. A package drive roller 33 on a drive shaft 32 is positioned between the guide means 28, 29. The guide means 28, 29 are rotatable on the shaft 32 and geared to the shaft 12 of the roller 1. In this embodiment the thread remains permanently in the guide 16 but during the period that the guide reverses its direction of motion the thread enters groove 30 or 31 to be guided by said groove pending reversal of the guide 16. Fig. 7 (not shown) shows a transmission (41) that continuously varies the speed of rotation of the roller 1 about a mean value, the drive roller (8) for the package being driven via the transmission (41) at a constant speed. Fig. 8 shows a drive arrangement comprising a common source of alternating current 42, a synchronous motor 43 driving the package drive roller 8, and a rotary transformer 44 that energizes the synchronous motor 45 driving the threaded roller 1. This causes the roller 1 to vary its speed continually about a mean valve whereby ribbon winding is avoided.

Patent ES-449080-A1 (ES)
Title: Article presence sensor
IPC: G01V3/08
Filed: 1976-06-21
Abstract: Apparatus for sensing the presence of an article. One end of a very high impedance resistor is held at a fixed voltage. The other end of the resistor is connected to a sensing element. When an article is placed close enough to the sensing element, a form of capacitive coupling to ground is created which causes a minute current flow through the resistor. This causes a small voltage drop across the resistor. The current and voltage difference are presented to a voltage follower which effectively amplifies the current. Sample and hold circuits furnish a signal which indicates the actual voltage level. A minimum level detector measures the voltage level with no article present. This level is compared with the sample and hold signal, and an article present signal is generated if the sample and hold signal is a pre-selected amount greater than the minimum level.
