Title: Improvements in and relating to devices for threading weaving shuttles automatically
IPC: D03J5/24
Filed: 1932-10-06
Abstract: 387,288. Self-threading shuttles for looms. SUMMA, H., Schwarzenbach-on- Saale, Germany. Oct. 6, 1932, No. 27787. Convention date, Feb. 24. [Class 142 (iii).] A self-threading device for a shuttle consists of two wires 7, 8 secured in a shuttle having a threading recess 3 and the usual inclined slot 14 leading to the eye 4. The wire 7 is inclined in plan to the axis of the shuttle and is curved downwardly from 7a to the part 7b which is situated below the threading point 8a of the wire 8. When the shuttle first moves to the right, the weft slides along and down the wire 7, then under the part 7b, and over the part 8a of the wire 8. The weft thus assumes the zig-zag path shown in Fig. 5d. Further movement of the shuttle causes the weft to slip beneath the part 8a. On the next pick, the weft passes under the curved part 8b of the wire 8 and through the slot 14 to the eye 4, a hump between the parts 8c, 8d of the wire 8 preventing the weft from becoming unthreaded. Pins 9, 10 are provided at the outer end of the eye, while friction may be applied to the weft by felt, plush, velvet, &c. 6 in the slot 5 between the threading and bobbin cavities 3, 1.

Patent GB-426875-A (GB)
Title: Manufacture of acetic acid from acetaldehyde
Filed: 1933-10-11
Abstract: Acetic acid is made by oxidizing acetaldehyde in presence of acetic acid or of a solvent for acetaldehyde and acetic acid, by means of oxygen or air in presence of ozone but in the absence of a solid catalyst at a temperature above 0 DEG  C.  The temperature may be regulated by internal or external cooling, or part of the reaction liquid may be cooled and then returned.  Acetaldehyde itself may be used as the solvent.  The ozone is completely consumed, and if air is used as the oxidizing gas, the exit gas after removal of organic materials may be pure nitrogen.  The exit gas may be used for <PICT:0426875/IV/1> operating a compressed gas pump for conveying the liquids for washing the nitrogen.  The apparatus may be reaction towers, packed columns or shaking or stirring apparatus, and may be divided into several sections, and the acetaldehyde and oxidizing gas may be passed in the same direction or in counter-current.  In an example a tower A is charged up to its overflow P with crude acetic acid containing acetaldehyde and heated to 58 DEG  C.  Ozonized air is supplied at 3--6 atmospheres pressure at C and passes through a filter plate B, and acetaldehyde is supplied at E.  The temperature is controlled by circulation of the liquor by the overflow P, cooler D and inlet E.  The exit gas escapes at K and is washed in a packed tower L with acetic acid drawn off at M, the acid from the base of the tower L passing to a compressed gas pump Qu in which nitrogen from the top of the tower raises it to a separator R from which it returns to the process, but the amount corresponding with that produced in A overflows at F to a still G in which remaining aldehyde is expelled through a column H to a condenser J from which it is returned to the inlet E.  The nitrogen passes out through a cooler N. In another example, the reaction temperature is maintained at 50 DEG C. and the tower L, pump Qu, separator R and cooler N, are dispensed with, the acid being withdrawn at a second overflow above the overflow P.  The Specification as open to inspection under Sect 91 includes another example in which the reaction is effected in a vessel having stirrers and a perforated plate for distributing the oxidizing gas, with circulating means to an external cooler. Acetaldehyde containing some manganese acetate is added as the cooled liquor returns to the reaction vessel.  The temperature is 40 DEG  C. and the pressure atmospheric.  This subject-matter does not appear in the Specification as accepted.ALSO:In the production of acetic acid by oxidation of acetaldehyde with ozonized air, the exit gas after scrubbing with acetic acid and cooling to remove vapour of acetaldehyde and acetic acid, is substantially pure nitrogen.

Filed: 1949-11-03
Abstract: 681.718. Mining-machines. MARCEROU, P. Nov. 3, 1949, No. 28135/49. Class 68(i) A rock-cutting machine comprises a platform 1 slidably mounted on guidetubes or rails and having formed on it a pivot 7 about which can rotate a platform structure 6, 8, 13; 14 and 16 on which is mounted a motor 9 that can, through a reduction gear box, rotate a cutter bar- 19 the outer end of which is reduced and supported on the arm 16 of the platform structure in a bearing 17. This reduced end has secured thereto a bevel gear which meshes with the bevel gear of a rotarycutter 23. A screw conveyer 27 behind the cutter bar is driven from said cutter bar. To advance the machine, a drive is taken from the gear box to a winch 37 on platform 8 via a clutch and the winch cable 38 passes forward over at least one fixed pulley to return and be anchored on the platform 1. The platform structure can be rotated through a right angle by a hand rotated pinion 42 meshing with a rack quadrant 41 on the platform. In use the loader part starts parallel with the rock face and the platform is rotated towards the face. The cutter 23 penetrates the face first and is of such a size as to clear a passage for the arm 16 and then the cutter bar cuts away the face. This rotation of the platform continues until the cutter bar 19 is perpendicular to the tubes and the machine is then hauled along the tubes which are formed of joined-together short tubular lengths. Bolts 48 projecting through slots 47 in the plate 8 contact the inner sides of the tubes 3, 4 to take up rotational thrust during the advance of the machine along the rails. For cutting blocks in one operation two such machines may be assembled on guide tubes in superimposed relation and may drive a third bar cutter spaced between the ends of the bar cutters of the two machines.
