Title: Improved apparatus for the washing and other treatment of artificial silk yarns
IPC: D01D10/04
Filed: 1932-10-13
Abstract: <PICT:0390440/IV/1> For the washing, desulphurizing, bleaching, and reviving treatment of artificial yarns in the forms in which they are delivered by the spinning operation, there is provided a vat with a channel around its upper edge, and a cover, the peripheral edge of which is adapted to dip below the surface of a liquid contained in the channel and thereby form a liquid seal.  The vapours of volatile liquids are thus prevented from escaping into the surrounding atmosphere, and carbon bisulphide which is liberated during the washing process may be recuperated simultaneously.  The vat may form part of an apparatus in which treatment liquids are forced or sucked transversely through the material wound on perforated bobbins.  In this case, the bobbin covers may be carried by a frame which is suspended from the vat cover.  As shown in the drawing, bobbins 2 wound with artificial yarn are placed over perforations in the bottom of a vat 1 and liquids are caused to pass transversely through the wound material.  The edges of the vat cover 5 are adapted to dip into the channel 6 containing a liquid in order to seal the interior of the vat from the surrounding atmosphere.  The vat may be provided with a pipe for leading away the vapours which collect beneath the cover.  The cover is raised and lowered by ropes 9 passing over pulleys 10 to a winch.  Chains 12 attached to the cover 5 support a frame 13 which carries the bobbin covers 14.

Title: Improvements in or relating to paper and the like applicable for music rolls and other purposes
IPC: D21H17/22
Filed: 1922-10-25
Abstract: 203,567. Hydroloid, Ltd., (Exportingenieure f³r Papier und Zellstofflechnik Ges.). Oct. 25, 1922. Paper, treating with special materials; arti. ficial leather.-In the production of paper and the like, applicable for music rolls and for the cards used in weaving machines and in sorting and classifying machines, the paper is treated preferably before perforation, with a sizing material such as animal size, casein, or albumen, squeezed between pressure rolls, either during or after sizing, and hardened by alum, chrome salts, formalin, or other hardening material mixed with the size or applied subsequently. After treatment, the paper is rolled up wet and allowed to stand for 24 hours, and is then dried on skeleton drums through which warm air is blown. The absorption of the size is improved, and the duration of the sizing reduced, by adding to the size an acid such as lactic acid, or an alkali such as caustic soda. By blowing cold air on to the paper before drying, pores and hair cracks are avoided. After hardening, the paper may be softened and rendered tough, like leather, by treatment with glycerine, soap, castor oil, or the like. A coating of varnish, applied after the treatment with glycerine, prevents the glycerine from absorbing moisture and renders permanent the flexibility and tenacity of the material. For music rolls intended for tropical countries, the paper may be treated finally with molten or emulsified wax or the like.

Title: Improved means for detecting leaks in electric cables or pipe lines containing fluidunder pressure
IPC: G01M3/28
Filed: 1945-11-06
Abstract: 603,935. Cable systems. BRITISH, INSULATED CALLENDERS CABLES, Ltd., and HOLLINGSWORTH, D. T. Nov. 6, 1945, No. 291323. [Class 36] [Also in Group XXVIII] In an electric cable system in which the cable dielectric is maintained at superatmospheric pressure by means of pressure-fluid., the system is divided into sections and leak of fluid in any particular section may be located at a distant station by an electrical method depending on the resultant fall of pressure in that section. The Figure shows three sections of such a cable carrying conductors 22 and supplied with pressure-fluid through a rate of flow indicator 2 and entry passage 3 ; barriers 4 separate the sections. A passage 8 through each barrier connects adjacent sections, this passage being normally open but adapted to be closed by a valve 10 actuated electrically by means of a solenoid 26 connected to pilot conductors 11, 12 and controlled by a switch 15 at the distant station. Each section also contains an automatic pressure switch 17 normally kept open by fluid pressure on a piston 28, but adapted, on the pressure falling to a predetermined value, to be closed by a compression spring 29 acting on a plunger 18. A resistance 19 connected across pilot lines 12, 13 is then brought into the circuit of a resistance measuring bridge 21 at the station. When a leak in the system is suspected by the rate of flow indicator showing an abnormal inflow of pressure-fluid, the switch 15 is closed so that each section of the cable is isolated, and the subsequent drop of pressure in the leaky section enables the resistance of that section to be measured on the bridge 21. Each resistance is of a different value so that the measurement is an indication of the position of the section.
