Title: An improved device for guiding threads during treatment such as washing or drying of artificial silk
IPC: D01D10/04
Filed: 1939-01-17
Abstract: 523,902. Rollers and roller heads. LUSTRAFIL, Ltd., and BARKER, S. W. Jan. 17, 1939, No. 1533. [Class 120 (ii)] [Also in Group IV] Threads of artificial silk are guided during treatment, such as washing or drying, by'means of a pair of similar rollers having conical portions, 4, 5 such that the threads would normally slip down, and the slipping is prevented by an inclined bar 6 over which the threads are passed. Each roller has cylindrical parts 1, 3 joined by the conical parts 4, 5 to larger cylindrical parts 7, 8, and inclined bars 2, 9 are associated with the cylindrical parts. The threads first pass over the roller 1, guide bar 2 and roller 3, then a stretch is imparted by their passage over the conical parts 5, 4 and the bar 6; they are afterwards passed over the rollers 7, 8 and are automatically guided at the desired spacing by the bar 9. In a modification the rollers are placed askew with their axes inclined to a -median plane to which the bar 6 is also inclined, and the bars 2, 9 are omitted.

Title: Improvements in and relating to the treatment of carbonaceous materials with hydrogenating gases
IPC: C10G1/06
Filed: 1934-01-18
Abstract: <PICT:0431795/III/1> In a multi-stage process of destructive hydrogenation in which the carbonaceous materials are treated initially in the liquid phase and finally in the vapour phase, the products from the first stage are separated in a catch-pot maintained under such conditions that no condensation takes place, i.e. at a temperature less than 20 DEG  C. below that of the reaction vessel, and the vapours are passed without condensation to the vapour phase stage.  Crude oil supplied through a line 1 and mixed with hydrogen from a line 3 is passed through a preheater, where it is heated up 400 DEG  C., into a reaction chamber 7.  The reaction products are separated in a hot separator 13 from which liquids are removed through a line 17 or recycled through a line 16 while vapours pass, with or without further heating in a coil 22 into a vapour phase reaction chamber 29 maintained about 390 DEG  C. by passing cold hydrogen through tubular conduits not shown.  The vapours produced are condensed in a cooler 31 and separated in a separator 32 from gases which are recycled through lines 36, 38.  In a modification the vapours after leaving the catch-pot may be condensed and treated with hydrogen at 200--300 DEG  C., to remove unstable constituents, prior to final treatment in the gas phase.  The use of the usual catalysts mounted stationary in the reaction chambers is specified. Specifications 336,610 and 338,576, [both in Class 32], are referred to.

The nozzle shown in Fig. 1 produces a converging jet of fluid owing to the conical shape of the opening 2. Various other nozzles are described in which parallel, cylindrical or divergent jets are produced by combinations of convex or conical bearing surfaces and convex or conical seating surfaces. Some of the nozzles have means, e.g. a wall 8 as shown in Fig. 1, whereby when the supply of fluid is stopped, the shutter member 5 does not slide back to a position from which it cannot be returned to the opening 2 with the same orientation when the supply recommences. The number and cross-sectional shape of the grooves 7 can be varied. In a modification, Fig. 12, the nozzle comprises a head 71 formed with six grooves 77, a hollow shutter member 75 having eight fingers 78, and four parallel ribs which guide the shutter member 75. The fluid issues through an inlet 80, flows between the gaps in the fingers 78 and is discharged through the grooves 77 as a parallel jet.

Patent GB-375314-A (GB)
Title: Improvements in and relating to the production of formaldehyde
IPC: C07C45/33
Filed: 1931-01-20
Abstract: <PICT:0375314/IV/1> Formaldehyde is obtained by passing methane together with oxides of nitrogen and gases which contain a split off oxygen, at temperatures below the ignition point of the mixture, over catalysts consisting of one or more of the elements platinum, tungsten, chromium, copper, silver, nickel, zinc, manganese, or silicon, or oxides thereof.  Steam may be employed as a gas splitting off oxygen.  When metals are used as catalysts, they may be inserted as resistances in an electric circuit, in the form of wires, gauzes, lamin , or the like.  Wire spirals made from alloys containing 56 per cent copper, 31 per cent nickel, and 13 per cent zinc, or containing 88 per cent nickel and 12 per cent chromium are used in examples.  In another example a mixture of oxygen and nitrogen oxides is led through an opaque quartz glass tube heated to 620 DEG  C.  The initial mixture of methane and oxygen may be supplied with nitrogen oxides by a preliminary passage through an electric arc.  The process may be carried out by supplying methane or a gas such as coke gas or natural gas containing methane from a container 1 to a mixer 5 through a pipe 4, nitrogen oxides being supplied to the mixer 5 from a container 2, and oxygen being either supplied as air by means of the air pump 3, or introduced into the mixer 5 from a separate container. The reaction takes place in the chamber 6, the necessary temperature being attained either by external heating or by electrically heating the catalysts contained therein.  Water vapour produced in the reaction is condensed in the cooler 7 and separated in the receiver 8.  The residual gases are led to a washer 9, wherein the formaldehyde still contained therein is dissolved by water sprinkled over cascade or other filling surfaces.  The solution is collected in a vessel 10, whence it is returned by a pump 11 to the washer 9 until it contains 20 to 25 per cent formaldehyde.  The solution is then led through a three-way cock 12 into a collecting vessel 13.  The residual gas may be returned to the reaction chamber 6 or worked up in a second similar plant.  The formaldehyde solution from the vessel 13 is brought to a strength of 30 to 40 per cent in a rectifier 14 and is finally collected in a vessel 16.  The weaker solution from the rectifier 14 is held in a collector 15, and returned to the washer 9 by way of the vessel 10.  According to the Specification as open to inspection under Section 91 (3) (a), the catalysts used comprise one or more elements selected from series 3, 4, 5, 7, and 8 of groups I, II, IV, VI, VII or VIII of the periodic table, or one or more oxides thereof. Magnesium is specifically mentioned.  This subject-matter does not appear in the Specification as accepted.
