Title: Improvements in or relating to weft feeler mechanism for looms
IPC: D03D51/34
Filed: 1923-01-11
Abstract: 211,309. Wade, H., (Salt's Textile Co. (Soc. Anon.)). Jan. 11, 1923. Weft - feeler arrangements; shuttles; shuttles, changing g bobbins in automatically.- Weft feeler mechanism for stopping a loom or causing bobbin changing, when the weft on a bobbin B, Fig. 7, is substantially exhausted, comprises a feeler rod 54, or two feeler rods 54, 55 in the case of a double shuttle loom, slidable freely in tubular sleeves 50 having bored end-plugs 52 and normally acted upon merely by the depending arms 32 of bell-crank levers 34 pivoted on a stud &c. 26 on a lug on a collar 24 on a rod 23. The feeler-rods are normally pressed by the arms 32 towards the shuttle boxes to an extent limited by collars 50, and at the beat-up enter through apertures 56 in the shuttle boxes and slots or openings 61 in the shuttles. Normally the weft on the bobbins then engages the feeler rods and presses them forwards, whereby the levers 32, 34 are rocked, but if the weft is sufficiently exhausted in a bobbin it exposes a recess or opening or slot 63 into which a feeler rod enters, so that the corresponding hooked lever 32, 34 remains in position to be engaged by a broad-armed latch 36 adjustably secured to a cam-controlled lever, the rod 23 is thereby moved and operates a knock off lever which disengages a spring shipper lever from a detent, this lever stopping the loom either by shifting a fork for the driving belt or by operating a switch to cut off the electric current from the motor which drives the loom. The two feeler sleeves 50 are supported adjustab'y from a bracket 44 by eyebolts, and are offset, the upper sleeve being set farther away from the bracket than the lever sleeve. The bobbin may be provided with an extra length of yarn wound around a groove to provide yarn for a few extra picks after the feeler mechanism has indicated for loom stoppage, thereby preventing half picks in the cloth. In a modification, the application of the feeler device to a single shuttle loom having bobbin-changing mechanism is described, the slide rod carrying the feeler-controlled bell crank hooked lever being connected by a link to an arm on a shaft 81, Fig. 5, which is provided with a crank arm 94 connected by a telescopic link 93 to a block 89 pivoted to the transferrer, this block being raised into the path of the lay bunter 91, when the shuttle is almost exhausted, whereby the transferrer is actuated, the link 93 yielding slightly as the transferrer is actuated, so that the rock shaft 81 is not turned and the slide rod is prevented from exerting pressure on the latch whilst this is in engagement with its hooked lever.

Title: Cycloalkane hydrocarbons and method for their production
IPC: C10G65/08
Filed: 1964-03-20
Abstract: Hydrocarbons rich in cycloalkane hydrocarbons and in particular mixtures thereof completely free from olefins and containing at least 95% of fully saturated hydrocarbons are prepared by introducing an essentially aromatic raw material such as a fraction of coal tar, a hydrogenate of coal or a material of petroleum origin rich in polynuclear aromatic hydrocarbons into a first hydrogenation stage in presence of a strongly hydrogenating catalyst comprising a sulphide of tungsten and/or nickel or alumina under a hydrogen pressure of 100 bars or above at temperatures not exceeding 450 DEG  C., cooling the effluent from the first stage and introducing the effluent into a second stage using a catalyst comprising a sulphide of tungsten and/or nickel or alumina at a hydrogen pressure exceeding 100 bars, the reaction conditions and the temperature of the effluent being such that the upper limit of temperature in the second stage is less than the upper limit of temperature in the first stage and is between 260 DEG  and 400 DEG  C. and preferably 300 DEG  to 380 DEG  C. At least 3000 litres of hydrogen measured at S.T.P. are used per kilogram of starting material and any excess hydrogen is washed under pressure using various solvents to eliminate any hydrocarbons and is then recycled to the first hydrogenation stage.  The product may be washed with selective solvents, e.g. methanol to remove oxygen, sulphur and nitrogen containing compounds and the final product may be distilled preferably in the absence of oxygen.

Patent GB-786895-A (GB)
Title: Improved method of extrusion and die structure therefor
IPC: B29C48/09
Filed: 1955-01-17
Abstract: <PICT:0786895/IV (a)/1> Elongated shapes are made from molten polyamide by extruding it through a die and then directly into a water bath, the die being made of polytetrafluoroethylene (P.T.F.E.) having silica particles dispersed therein, the silica comprising 5-65 per cent by weight of the total weight of the die.  The silica imparts hardness and wear resistance to the P.T.F.E.  The silica may be of the highly porous type, and may be used as very small particles, e.g. 0.5 to 60 microns, the pore size being from 20 to 100 Angstrom units.  In making such a die of 100 g. weight (of which 30 g. are silica) an aqueous suspension of P.T.F.E. and finely-divided silica are mixed and ground together to form a dough-like mass which is dried and broken into pieces.  The pieces are hot-pressed to the die shape and a hole is bored therein to form, for example, the die 11 shown in Fig. 2.  This die 11 forms part of an extrusion crosshead for making polyamide tubes, including an outer assembly 6, 7, 8, a nozzle 10 and an inner longitudinally-adjustable mandrel 12 having a central air-passage extending therethrough.  The polyamide tubing is extruded into a setting bath 16 kept below 90 DEG F., and is reeled at 20.  This bath consists of water plus a wetting-agent, e.g. "Aerosol OT" (R.T.M.) (sodium dioctyl sulphosuccinate), or an agent that is both wetting and lubricating, e.g. "Ultrawet 35 KX" (a sodium salt of sulphonated petroleum hydrocarbon).  The effect of such an agent in the bath is to improve the heat transfer between the surface of the solidifying polyamide tube and the bath, and to improve the surface smoothness and dimensional accuracy of the tube; moreover, since the die is in contact with the bath (as shown in Fig. 2 the die shuts an aperture 18 in one end of the bath, the liquid level being at L) any lubricant in the bath lubricates the die.  To reduce chilling of the die a washer 14 is disposed between the bath and the die. Specification 597,006, [Group IV], is referred to.
