Patent ES-360694-A1 (ES)
Title: System for converting continuous filament tow into staple sliver
IPC: D01G1/10
Filed: 1968-11-26
Abstract: Continuous filament tow is converted into a sliver having uniform staple length fibres by (a) feeding at least two webs 10, 12 of tow from a supply source 8, (b) cutting the filaments into staple length fibres by cutter rollers 24, 26 (c) superimposing he webs to form a single web, (4) condensing the width of the webs at station A, and (5) feeding the webs to a gill station B. The gill station has faller bars which engage the web at a distance from the nip of the back draft means (which forwards the webs) at a distance shorter than the length of the cut staple fibres, the bars moving away from the nip at a speed faster than the linear speed of the web through the nip. The gill station also has a front draft means which forward the web at a speed faster than the speed of the web through the gill station. The sliver may then pass through a second condensing station F, and then through a second gill station G before passing around wedgeshaped rollers J, which serve to further condense the sliver, and thence into coiler K. A web of staple fibres W, e.g. wool fibres, may be blended into the sliver upstream of the back drafting rollers 46, 40, 41 of the first fill station. Waste is withdrawn from the web by suction heads attached to vacuum source V at the gilling stations. Each pair of cutter rollers 24, 26 may comprise a roller having a helical cutter element thereon which forms a nip with an anvil roller. One helical cutter roller is righthanded while the other helical cutter roller is left-handed so that when superimposed the single web has the diamond-shaped cutting pattern in plan elevation. The front pressure draft roller 72 of the second gill station has a concave surface so that an equal amount of pressure is distributed across the width of the web. Specification 1,246,334 is referred to.

Title: Reciprocable platen in selective print wheel printing machine
IPC: G06K15/06
Filed: 1969-10-16
Abstract: A desk type peripheral equipment for use with a computer to feed in and receive out numerical information on which the computer will perform arithmetical calculations comprises a unit, Fig. 1 (not shown), having one set of keys 0-9 plus decimal point and a second set (202) for directing the information. Depression of any 0-9 key causes through a linkage a combination of switches to be operated which energize a corresponding number of electromagnets 301a-301c, thus releasing one or more gears 321a-321c which transfer a part of the rotation of a shaft 307 through the gears 306a-306d having numbers of teeth arranged in a binary progression, i.e. 1, 2, 4 &c. to a set of gears, e.g. 351a, each acting as a store and mounted on shaft 337. An interlock actuated either through a linkage or a captive ball arrangement prevents simultaneous depression of more than one key. When all digits of a number have been recorded, a function key, i.e. +, - is depressed, which causes the gears on shaft 337 to simultaneously engage and rotate through intermediate gears printing type characters 503 carried on another shaft 504. After rotation to the appropriate positions, the type characters are held temporarily by a spring-loaded locking bar and a resilient printing roller 534 is moved through an arc to press paper from a feed roll against an endless inking tape and the type characters. The arc of movement of the roller is limited so that the meeting face does not pass below the bottom of the type hence avoiding movement of the paper and consequent smudging. As the print line is two spaces below an observation window (512), Fig. 1 (not shown), in the unit, a mechanism is included to advance the paper a corresponding amount after each printing operation, and to retract it one space before the next printing operation. The unit may be operated so that information may be received concurrently with the printing operation. A register may be employed to develop binary signals in serial form for feeding into a computer and also receive information from the computer in serial form and convert it into parallel signals to operate the printing mechanism. The unit may be constructed with internal electronic computing and data processing circuits to form a complete unit but such circuits do not form part of the invention.

Title: Magnesia-containing refractory dressings
IPC: B22D27/18
Filed: 1970-03-12
Abstract: Ferrous metals are cast in an ingot mould whose walls or the base-plate thereof have been coated either with an aqueous liquid refractory dressing comprising particulate refractory material consisting of or including magnesia which particulate refractory material has a "residual hydration ability" of less than 4% by weight and, as binding agent, an alkali metal silicate or a refractory dressing precursor comprising the particulate refractory material previously specified and a solid alkali metal silicate. The percentage residual hydration ability of the material is defined as the percentage weight loss on heating a dry sample of the hydrated material at 600 C. for 2 hours. The magnesia should preferably have a low calcium oxide content and preferred magnesias are dead burnt magnesites. The particulate refractory material may also include alumina, titania or zircon whilst the magnesia may contain iron oxide as impurity. The alkali metal silicate used is preferably sodium silicate, most preferably sodium metasilicate. The amount of water used in the liquid dressings should preferably be sufficient to cause hydration of the alkali metal silicate to at least 10 H 2 O. When sodium silicate is used the magnesia and sodium silicate react in use to form the refractory magnesium silicate "forsterite". Optional ingredients specified are a Xanthomonas colloid suspension agent and a particulate suspending agent, e.g. bentonite.

Title: Improvements in textile spinning machines
IPC: D01H4/00
Filed: 1970-09-12
Abstract: In a break spinning machine consecutive spinning stations S2, S3 &c. are served by two rows of winding units, consecutive winding units in each row serving alternate spinning stations. Each spinning station has two boffins 19, 19' driven by a roller 35. Yarn is wound on either bobbin and when a package is completed is transferred to the other bobbin either by an arrangement as described in Patent Specification No. 1,139,695 or a device as shown in Fig. 4. The device of Fig. 4 comprises two reciprocating yarn guides 48 and 48' carried by a rod 121 which build up the package. Yarn is transferred from one bobbin to the other by the unit S4 being traversed by means of a pneumatic ram (not shown). As the unit S4 moves across a guide pin 62' lifts the yarn from the guide 48' and carries it across to where it runs up slope S2 to engage yarn guide 48. As the yarn is carried across it is picked up by a hooked mat 63 which winds on the first few turns. A bar 65 tilts forward to allow initial threading up into slots 58 and 59 through a slot 156. Yarn between bobbins is cut by a knife (not shown) and the full package is doffed by depressing a foot pedal 42, see Fig. 3 (not shown) which pulls a wire rope (44, 44') to disengage the package from the roller 35 by tilting a mounting arm (31, 31') against a spring (33, 33'). Even package winding is ensured by dampers (47, 47').
