Title: Device and process for guiding and conveying yarns or threads
IPC: D01D10/04
Filed: 1974-08-05
Abstract: 1482985 Thread guides with fluidflow HOECHST AG 5 Aug 1974 [4 Aug 1973] 34455/74 Headings D1D and D1F In a device for guiding and conveying thread, in which fluid imparts momentum to the thread, the thread inlet may be enlarged to facilitate threading up. In a stuffer box injector nozzle, Fig. 1, fluid flows from inlet 1 through annular slit 3 whose width is set by spacer ring 6. Four threads are sucked into bore 7 and conveyed by the fluid, the threads are then each located in a slot 9 in element 8, and the element is moved by device 10 to fit tightly in bore 7. Alternatively (Fig. 4, not shown) element 8 has only one groove 9 which is engaged by an inner, longitudinal projection in bore 7. In a suction gun, Fig. 7, fluid flows via conduit 12, zone 13 and annular slit 14 whose width is set by screwing tube 18 in tube 19. Two segments 16 form thread inlet channel 21. To thread up, rod 24 is pulled against spring 25 to pivot four guides 22, 23 about pivots 26, 27 so that the segments are raised from nozzle 15 and placed to one side. Simultaneously, Fig. 8, springs 29 part segments 16.  After threading, rod 24 is released and the segments move into nozzle 15 which closes them so that inlet 21 reforms about the running thread. Alternatively, Fig. 9, inlet channel 21 is formed by four segments 16 each having one pin 36 engaging an eccentric groove 35, Fig. 10, in cap 33 on coarse thread 34. When cap 33 is rotated the segments rise with the cap and segment rotation is prevented by fixed pins 37 engaging segment slots 38. Simultaneously grooves 35 part the segments. The amount of fluid flowing may be reduced when the thread inlet is enlarged.

Abstract: 1283420 Mechanical digital data storage devices HI-SPEED CHECKWEIGHER CO Inc 30 June 1970 [10 July 1969] 34917/71 Divided out of 1283418 Heading G4B A mechanical digital data-storage device comprises storage elements 101a-101h, 102a-102h, &c. arranged in axially aligned rows 101, 102, &c. with elements 101a, 102a-109a, 101b, 102b-109b, &c. forming circumferential columns, all the elements being mounted in a rotatable cylindrical drum 100 indexable such that each of the rows 101, 102, &c. may be brought successively to setting means 99a-99h, cancel means 110 and element sensing means 111, 112, 113, &c. The sensing means are disposed circumferentially and axially of the drum, one to each of rows 102-109 and each to a different column. As shown, the storage elements comprise axially movable pins having heads (131), Figs. 7a, 7b (not shown), and stems (130), the radially inner ends of which are engaged by the setting means or pistons 99a-99h of pneumatic cylinders 98a-98h to be moved radially outwards to the store position. In this position, heads (131) engage the appropriate microswitch sensing means 111, 112, &c. In the embodiment described, see also Specification 1,283,418 (see Division G1 and Specification 1,283,419 (see Divisions C1 and B7-B8) the data-storage device is incorporated in an apparatus for sorting articles into eight categories determined by weight, each weighing at station (16), Figs. 1 and 2 (not shown), operating one of eight solenoid operated valves (97a- 97h and hence an associated one of setting cylinder and piston assemblies 98a, 99a, 98a, 99b &c. A timing mechanism (65), Fig. 6 (not shown), causes reciprocation of cancel means 110 to clear the row positioned therebelow, row 101 as shown, prior to setting of one of valves 97a-97h. On indexing of drum 100 by drive means (142), Fig. 6 (not shown), associated with timing mechanism (65), row 109 is brought into alignment with the setting and cancel means and at the same time a set pin in one of rows 108-108 may operate one of sensing means 111-118, see also Fig. 5 (not reproduced). For example, if pin 101a had been set previously, the single indexing of drum 100 would bring head (131) of pin 101a into contact with microswitch sensing means 111. The sensing means 111-118 control cylinders (164a-164h), Figs. 1 and 2 (not shown), associated with take-off conveyers (180a-180h), which dump similar weight category articles on to the same conveyer.

Title: Improvements in or relating to yarn for the hand or machine knitting of articles of hosiery
IPC: D02G3/28
Filed: 1935-12-16
Abstract: 467,577. Producing composite yarns. ALEX, M. A. Dec. 16, 1935, Nos. 34935 and 34936. Convention dates, Dec. 15, 1934 and Oct. 17, 1935. [Classes 120 (ii) and 120 (iii)] A composite yarn for knitting purposes is produced by twisting together a number of yarns having different degrees and /or directions of twist to constitute a component element, a number of such components being twisted together in the opposite direction of their individual twists to form a composite yarn of low twist of which the components have a low or moderate twist and consist of yarns twisted to different degrees and in different directions. The composite yarn is loose, soft and full, and is capable of stretch of the order of 50 per cent of its normal length. The initial yarns may be formed of silk or rayon, alone or combined with yarns of animal or vegetable material. The Specification as open to inspection under Sect. 91 comprises also apparatus for the manufacture of the yarn wherein (1) the surface contact of a leather band-brake with " the thread bobbin destined for obtaining" the yarn is varied in proportion to the diameter of winding ; (2) the "adherence of the silk spools" is ensured by a set of two equal weights attached "at an intermediate point of the griff of each spool," one weight hanging "direct" and the other hanging on the pivot of " the griff " so that, during winding, "the griff" is subjected to a pull proportional to the difference between the radius of the pivot and the distance between the pivot and the point of attachment of the weights, and, when raised, to a pull from "bottom to top" whereby it is maintained in this position ; (3) the bobbin is separated from its "actuating cylinder" by a spring-actuated plate released by a finger on arms supporting a cylinder in contact with the yarn. It is also stated that the yarn "can equally be applied to weaving with a view to obtaining any kind of fabric." This subjectmatter does not appear in the Specification as accepted.

Title: Cameras
IPC: G03B19/12
Filed: 1976-08-24
Abstract: 1517468 Camera viewfinders FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE ] 24 Aug 1976 [3 Nov 1975] 35160/76 HeadingG2J A viewfinder system for a reflex camera has a focusing screen which is formed as part of a liquid crystal cell. In Fig. 1 the viewfinder is shown as comprising two flat plates, 1, 2 of transparent glass or plastics material, spaced apart by a film 3, the space between them being filled by a nematic liquid crystal. The inner faces of the plates have transparent conductive layers 5 and 4, with respective current supply leads 7, 6. Layer 5 has at its centre a recess 5a, aligned with a micro-screen spot 9 on plate 1. Layer 5 is also interrupted along a ring 5b, so dividing it into electrically separate portions 5c, 5d, the portion 5d also having a separate supply lead 8. Different types of focusing screens may be produced merely by varying the voltages suitably on the different supply leads, without the necessity for having inter-changeable screens. Thus if a voltage is applied between leads 6 and 8, a local turbidity occurs in the liquid, so producing the effect of a frosted ring 5d. Such a screen is particularly suitable for photography in poor light. If there is zero voltage across leads 6 and 8, the screen is completely clear. In Fig. 7 (not shown) the microscreen area 9 is covered with a separate conductive layer having its own supply lead. In Figs. (not shown) 3-6, one plate of the crystal is formed by the plane face of a field lens or a Fresnel lens, and the other plate may be formed by one face of the viewfinder pentaprism. In Fig. 8 (not shown) one of the conductive layers is formed as a reflective surface. One plate may carry at one edge a number of electrodes 16, so shaped as to indicate diaphragm settings, so that a voltage between layer 4 and the appropriate electrode 16 will render the diaphragm setting visible in the viewfinder.
Patent GB-849514-A (GB)
Title: Improvements relating to the production and use of di-alcohols
IPC: C08G63/682
Filed: 1958-11-03
Abstract: The invention comprises polyesters of dibasic acids with dialcohols of the formula R(OR 1OH)2 where R is a divalent polychloro-diphenyl radical containing at least 6 chlorine atoms and R1 is a divalent hydrocarbon radical and a process for their preparation by esterification of the acid and the alcohol.  The dibasic acid may be a saturated aliphatic acid, e.g. adipic acid, an unsaturated aliphatic acid, e.g. fumaric or maleic acid or an aromatic acid, e.g. terephthalic acid.  The reaction may be carried out by heating in an atmosphere of carbon dioxide and the polyester stabilised by addition of hydroquinone. The examples describe the preparation of poly [bis-(hydroxy-ethoxy)-octachlorodiphenyl fumarate], poly-[bis-(hydroxyethoxy)-octachlorodiphenyl fumarate adipate] and poly-[bis-(hydroxyethoxy)-hexachlorodiphenyl maleate]. Flame-resistant copolymers are prepared by copolymerising a polyester as defined above in which the acid component is an ethylenically unsaturated dicarboxylic acid with an addition polymerisable unsaturated monomer, e.g. styrene or allyl phthalate, e.g. in the presence of benzoyl peroxide or methyl ethyl ketone peroxide.  The examples describe the copolymerisation of the three unsaturated polyesters specifically mentioned above with styrene.ALSO:The invention comprises di-alcohols of the general formula R(OR1OH)2 where R is a divalent polychloro-diphenyl radical containing at least 6 chlorine atoms and R1 is a divalent hydrocarbon radical and a process for their preparation by heating an alkali metal salt of a dihydroxy-polychlorodiphenyl R(OH)2 with a chlorinated alcohol Cl-R1-OH or by heating an olefine oxide R1 = O with a dihydroxy-polychlorodiphenyl R(OH)2.  The reactants mentioned to introduce the group R1 are ethylene and propylene chlorhydrin, chlorocyclohexanol, ethylene and propylene oxide and epoxycyclohexane.  The alkali metal salt may be formed in situ from an alkali metal hydroxide and a dihydroxypolychlorodiphenyl, the latter compound may be obtained by controlled saponification of a polychlorodyphenyl, e.g., dihydroxy-hexa-chlorodiphenyl from octachlorodiphenyl.  The examples describe the preparation of bis-(hydroxy-ethoxy) hexachloro- and octachloro-diphenyl.  The di-alcohols may be converted to polyesters by reaction with dibasic acids and any ethylenically unsaturated polyesters may be copolymerised with an addition-polymerisable unsaturated monomer (see Group IV(a)).
