Title: Gas-liquid contact apparatns
IPC: B01D47/06
Filed: 1954-09-09
Abstract: 771,129. Treating gases with liquids. ALLARD CHEMICAL & DYE CORPORATION. Sept., 9, 1954 [Nov. 9, 1953], No. 26103/54. Class 55 (2). Gas and liquid contact towers comprise one or more superposed chambers each with a slotted plate 7 at the base through which gas is admitted from below mainly through peripheral portions of the slots, a spray head at the top providing a conical spray extending to the tower wall, and frustoconical baffles 28 inclined upwardly from the wall to the spray head for directing gas through the spray. In the form shown, apart from the top pressure spray head 16, gravitytype nozzles 18 are employed, each with an overhead collector pan 19 and tube 20. Incoming gas is baffled by depending plates 25 and directed round the wall by a distributer 22. Each of the slotted plates 7 comprises inverted V-shaped channels spaced to form slots for passage of gas and liquid, the middle portions of all the slots except those between the last two approaching the wall being partly blocked by covers so that in the main, rising gas is directed towards the wall. Redistributers 12 round the wall between the spray head and plate direct liquid out of contact with the wall. An entrainment grille 26 removes liquid from gas on its way out of the tower.

Title: Improvements relating to hoists
IPC: B66B13/20
Filed: 1923-10-20
Abstract: 227,901. Bower, S. Oct. 20, 1923. Lift cages and doors, locking and unlocking and operating.-In lifts provided with sliding bolts by means of which it is made impossible (1) to open a well door unless the lift is opposite thereto and (2) to start the lift before the door is closed, two handing chains E, E<1> are provided. The chain E passes through the lift, and the chain E' passes through the floors in position to be actuated by a person outside the lift. When the cage D arrives at a floor F an abutment d rocks the lever A and thereby withdraws the bolt a<2> from engagement with an aperture c in the latch c<1> of the door C'. On opening the door the spring b<4> rocks the lever B, thereby forcing the forked end b<3> of the rod b<2> into engagement with the handing chain E. The latch c' is also engaged by the hooked end of a pivoted lever g<8>, Fig. (i, which is rocked by a cam g<7> when a rod G slidably mounted in a tubular holder g is rotated. A tumbler plate g<4> at the end of the rod G normally engages a recess g<6> in the holder, but when it is engaged by the spring g<5> on the cage it is forced into the position shown in Fig. 4 and the bolt can be rotated by either of the handles g<1>, g<2>.
Patent GB-262633-A (GB)
IPC: B65B13/12
Abstract: 262,633. Parker, G. D. March 1, 1926. Wire strainers.-Relates to a machine for passing a wire around a bundle of articles. box, or package, tensioning, twisting and cutting the wire, so that a flat knot is formed which lies against the side of the bundle. The bundle is placed on rollers 9, Fig. 1, on a table 7, and and a wire 77 is passed round it by a wheel 78 mounted on rollers 79, and adapted to rotate in opposite directions for successive operations. The wire passes through a tensioning and straightening device comprising grooved rollers 83, 85, into engagement with which the wire is forced by rollers 86, 87 mounted on a lever adjustably held in position by a wing nut 93 and bolt, The wire then passes several times round rollers 96, 97, the latter of which is mounted on a spring-urged lever 98 so as to take up slack between the operations, and thence to rollers 80 on the wheel 78, the free end being held by a dog in the twisting and cutting mechanism 114. The wheel rotates through rather more than a complete revolution so that the wire is disposed around the package and an overlap is provided adjacent to the twisting mechanism. A twisting device comprising a slotted pinion engages the overlapping wires, and twists them together, after which the wire is cut and the driving shaft disconnected.

Title: Improved process for printing textile materials
Inventor: KRUG PAVEL
IPC: D06P5/15
Filed: 1956-08-31
Abstract: Textile fabrics made from polyethylene terephthalate, polyamides or acrylic fibres, are treated with a dischargeable dyestuff and printed with a discharge paste containing thiourea dioxide and a dispersed cellulose acetate dyestuff derived from anthraquinone and free from azo groups (in that order or in the reverse order), the proportion of thiourea dioxide being from 2 to 4 per cent of the weight of the discharge paste, and being such, within these limits, that it brings about the destruction of the ground shade without impairing the colour of the dyestuff in the discharge paste.  The discharge paste may contain 0.5-1 per cent by weight of a 1 : 1 aqueous ammonium nitrate solution, which accelerates the reoxidation of the reduced dyestuff, without impairing the reducing properties of the thiourea dioxide.  In an example, a "Terylene" (Registered Trade Mark) cloth is padded with an aqueous dispersion of 50 gms./lb. of a yellow dischargeable dye obtained by coupling diazotized 4-acetylaminoaniline with paracresol.  After drying, the cloth is printed with a composition comprising (all parts being by weight) 30 parts 1 : 4-diamino-2-methoxy-anthraquinone, 20 parts thiourea dioxide, 20 parts para-phenylphenol, 50 parts thiodiglycol, 380 parts water, 490 parts of a thickening agent, and 10 parts 1 : 1 aqueous ammonium nitrate.  The cloth is then dried and steamed for 5 mins. at 101-102 DEG  C., then heated for 2 mins. at 180-190 DEG  C., soaped in boiling soap solution, and rinsed and dried, a brilliant bluish-red print on a yellow ground being obtained.

Abstract: 220,200. Bartmann, L., and Naamlooze Vennootschap Maatschappij tot Exploitatie van Bartmann Patenten. Oct. 29, 1923. No Patent granted (Sealing fee not paid). Apparatus. - A machine for slicing granular materials, especially grains of corn, to produce thin discs, comprises a rotary hollow drum mounted on an horizontal axis and having perforations through which the grains can emerge, and a slotted cylinder surrounding the drum with a small clearance and having knives in the slots with their edge portions projecting into the clearance. Figs. 1 and 2 show views of a twin machine in which the hollow drums a with radial slots b are rotated at high speed by means of a belt pulley c, the grains being fed into the drums through tubes d. Wipers e, which may be in the form of brushes, extend into the drum adjacent the inner surface thereof and turn the grains over and cause them to enter the slots b. The knives g in the slots of the outer cylinder f have their edges in close proximity to the surface of the drum so that grains issuing from the holes b are sliced by the knives. The discs or slices pass through the slots of the cylinders f into an outer casing m leading to a shoot l. In a modification, the knife cylinders f are also rotated. Fragments of discs are obtained by using knives with toothed edges.
