Title: Packeting machines
Inventor: ROHDIN JAMES OSKAR
IPC: B31B5/78
Filed: 1950-07-18
Abstract: 675,821. Erecting collapsed cartons. ESSSELTE FORPACKING AKTIEBOLAG. July 18, 1950, No. 17912/50. Class 94(i) In a packeting machine in which a collapsed carton having a foldable flap at one or each end is fed from a magazine and positioned obliquely in a rectangular recess in an intermittently-movable carrier with the or each flap projecting at right angles to the body of the carton, and on movement of the carrier is erected and pressed into the recess, the mechanism for erecting the carton includes grippers adapted to engage one or each of the projecting flaps and exert an outward pull thereon. As shown, collapsed cartons a are fed in succession from a magazine f by a reciprocating member g and positioned obliquely in rectangular recesses m in a rotary carrier i, the end flaps b passing over spring-loaded fingers j which turn them through a right angle. During the first step of movement of the carrier the flags are guided by side channels o in an arcuate guide member n, and towards the end of this step they pass between spring- loaded grippers 7 pivoted to plates s mounted on a fixed pivot v and located by an adjustable stop 11. A spindle t, interconnecting the plates is coupled by a link w to a pivoted arm x which is moved in the counter-clockwise direction by a projection 4 on an oscillatory disc y and returned to its initial position by a spring 5. The arm is temporarily locked in its operative position by the engagement of a spring-loaded pawl 2 in a notch in a fixed 'member 3, the pawl being released by a finger 6 on the return movement of the disc. As the flaps pass between the grippers, their forward edges are arrested by spring-loaded stops 9, pivoted to the plates s and supported on abutments 13, and the leading edge of the carton body is engaged by a serrated roller or rollers p, thereby causing the carton body to asume a slightly convex form. The arm x is then actuated to swing the plates s and cause the grippers to pull outwardly on the flaps so that as the leading edge of the carton is forced under the rollers p as the carrier comes to rest, the carton is partially erected, see Fig. 4 (not shown). At the end of the operative movement of the plates, the stops 9 are moved clear of the flaps by engagement with fixed abutments 12. After the release of the pawl 2, the plates return to their initial position, the grippers sliding idly over the flaps, and during the next movement of the carrier the carton is completely erected and pressed into the recess by the rollers p assisted by a blade spring 15. The rollers are mounted on a lever q adjustable by a screw r. The stops 9 may be omitted. The invention may be applied to a rectilinearlymovable carrier.

Title: A method of Flattening and Polishing Finely Divided Metal Particles
Inventor: CLAYTON ERITH TAINTON
IPC: C09C1/62
Filed: 1967-04-19
Abstract: 1,183,379. Making metal flakes. E. T. CLAYTON. 19 April, 1967 [22 April, 1966], No. 17943/67. Heading B3A. [Also in Division C3] Finely divided particles of metal not higher than zinc in the electro-chemical series are flattened and polished to form flakes by subjecting the particles to mechanical flattening forces in the presence of an aqueous medium containing a polishing agent and a flux to remove oxides from the surface of the particles or containing a material which acts both as a polishing agent and flux. The particles are polished and flattened in a ball mill in the presence of a weldment inhibitor if the particles are prone to adhere to one another. Defoamers, buffers, mica grinding agents to reduce the size of the flakes and detergents acting as wetting agents may be optionally added to the ball mill. Several examples of suitable polishing agents, fluxes and weldment inhibitors are given. At least 75% of the metal particles produced are minus 100 mesh and at least 50% minus 200 mesh. The flakes may be encapsulated with a second metal, e.g. zinc encased copper or copper encased zinc, by ball milling without a weldment inhibitor. The particles may be of Zn, Sn, Cd, Pb, Au, Ag, Cu, Ti, brass, stainless steel, bronze and aluminium bronze.

Title: Method of freeing carbon monoxide-containing gas mixtures from oxygen
Inventor: SILICH MATILDA ILLARIONOVNA
IPC: B01D53/62
Filed: 1966-04-25
Abstract: Oxygen is removed from gas mixtures containing carbon monoxide by reacting the oxygen with hydrogen, provided in stoichiometric excess, in the presence of a metallic copper catalyst supported on a carrier. A catalyst containing 10% copper, based on the weight of the silica gel carrier, may be prepared by impregnating dried silica gel with an aqueous copper nitrate solution, drying for 2-3 hours at 100-120 DEG C. and firing at 400 DEG  C. until the evolution of nitrogen oxides ceases followed by reduction at 200-250 DEG  C. for 4-8 hours with hydrogen or with the gas mixture to be treated. The oxygen removal process may be carried out at 150-220 DEG  C. with a pressure of 100-300 atm. using a space velocity of 1000-6000 by volume per hour or at 190-250 DEG  C. at atmospheric pressure using a space velocity of 1000-3000.  The removal of oxygen from carbon monoxide/hydrogen mixtures is exemplified and compared with the removal of oxygen from otherwise pure hydrogen containing 0.2% by volume of oxygen using the same catalyst.

Title: System of connections for regulating the strength of a current in the divisions of a two part divided current circuit
Filed: 1920-07-02
Abstract: 145,730. Krupp Akt.-Ges., F. Jan. 2, 1917, [Convention date]. Controllers with combinations of resistances.-- Sets of resistances are arranged in two parallel paths so that the contact-carrying members and the resistance-carrying members may be rotated without disturbing the current balance in the two paths. A shaft A carries a conducting-piece a<1> engaging a circularly-shaped resistance b<1> rigidly secured to a member B. Similar circularly-shaped resistances c<1>, c<2> are carried by a member C and these are engaged by contacts d<1>, d<2> on a member D. The members A, B, C, D are rotatable about the axis of the shaft A. If the shaft A is rotated in the direction of the arrow the distribution of the resistance b<1> between the two parallel paths is changed and the currents are correspondingly varied. A similar result is produced by the rotation of any single member. If the members B, C are operated together, the part of the resistance b' in the left-hand circuit is increased while the resistance c<1> is diminished to the same extent. The resistance in each branch of the parallel circuits is therefore constant and the currents are not varied. The resistances may be arranged in a rectilinear manner.
