Patent GB-594729-A (GB)
Title: Improvements in or relating to the production of quicklime
IPC: C04B2/00
Filed: 1945-05-02
Abstract: Alkaline earth (including magnesium) oxides are produced in granular form by drying and calcining without briquetting a mixture of alkaline earth carbonate and hydrated oxide and water. The process is described with reference to quicklime and is especially suitable for the treatment of finely-divided calcium carbonate from water-softening plants and chemical works.  Between 4 and 40 per cent. by weight of the output of lime is slaked and mixed with the carbonate and water, and the resultant mixture may be granulated or extruded, with or without admixture with a solid fuel, such as coal, coke &c. before being dried and calcined.  The extruded cylinders may be mixed with a dry powder containing the carbonate to prevent sticking, the powder being removed by screening before drying. Rotary or shaft kilns may be employed. The sludge from a water-softening plant may be mixed with quicklime and be run directly to a rotary kiln.

Title: Process for the manufacture of carbamide and formaldehyde products in presence of sulphonated amide derivatives, and products obtained
IPC: C08G12/04
Filed: 1936-04-22
Abstract: Urea and formaldehyde are reacted in the presence of a sulphonated amide, preferably p-toluene-sulphonamide, and powdered zinc.  During the primary condensation or before the reactants have boiled there may be added cheap soluble fillers, e.g. sugar refinery waste.  The solution of condensate is filtered, slightly reheated if cloudy, and dehydrated, preferably under reduced pressure, until under constant pressure, the temperature of the syrup rises 4 to 5 DEG  C. in 5 mins.  The product is soluble in water, alcohol, ketones, amd hydrocarbons and may be plasticized by glycerol or ethylene glycol; it may be gelled by the addition of an organic acid or salt; it may be used for the production of coatings which are finally hardened by spraying with ammonium phosphate solution, and of laminated blocks of resin alone or with glass, celluloid, or cellulose acetate.  An Example is given.  The Specification as open to inspection under Sect. 91 refers to the use, instead of metallic zinc, of a metal in pulverulent form, preferably one not causing colouration by oxidation or hydration. This subject-matter does not appear in the Specification as accepted.

Title: Feed mechanism for automatic wire-tying machine
IPC: B65B13/18
Filed: 1961-03-29
Abstract: 942,217. Tying machines. UNITED STATES STEEL CORPORATION. March 29, 1961 [April 4, 1960], No. 11539/61. Heading B8C. Mechanism for feeding wire to a tying machine comprises a driven drum 24, a fixed housing 22 fitting around the drum and having a helical wire-accommodating groove 26 on the interior with an entry end and an exit end for the wire in laterally offset paths, and two pressure rollers 46, 54 fitting in apertures formed in the housing along the groove at the exit and entrance ends respectively to engage the wire, the wire being fed along the groove by rotation of the drum in one direction, and retracted by rotation in the opposite direction. As shown in Figs. 1, 4, wire W is fed in through a housing 34, around the rotating drum 24 encased in a housing 22, through a guide tube 62, and into a guide track 12. The wire is helically wound around the drum 24 (see Fig. 7), fitting in slots 26 of the housing 22, the feeding of the wire being aided by sprung rollers 46, 54 which fit through apertures in the housing 22. In operation, the wire is fed along the above path, and around the guide track to overlap at the knotter station 10, where the free end is grasped by a gripper causing a switch 82 to be actuated to stop the machine. When a package P to be banded, arrives at the platform F a switch, either actuated by the package or manually, causes the drum 24 to be driven in a reverse direction, thus stripping the wire from the track. The wire tightenes round the package, and the ends are knotted and severed at 10. The surplus length of wire (see Fig. 4) passes into an escapement 16, and is engaged by tongues 76. After the knotting operation, the direction of rotation of the drum is reversed, and the cycle of operations repeated.

Attachments for screwing and tapping.-A device for screwing dies and taps for use in turret lathes comprises a stem a with a collar b upon which is mounted a sleeve e capable of longitudinal play, and to which are secured a holder d and a plate g. The collar b has clutch projections h which, during screwing, engage corresponding projections on the holder d, and spring- pressed plungers i which engage the plate g. A reversible one-way friction clutch, comprising blocks k, springs l, and rollers j, is interposed between the collar 6 and the sleeve e. When, during screwing, the turret engages a step, the clutch h is released. On reversing the rotation of the work, the roller clutch comes into action and holds the die or tap during the withdrawal.

Title: Improvements in or relating to a method of preventing back ignitions in metal vapour rectifiers having insulated anode sheaths
IPC: H02H7/127
Filed: 1928-04-20
Abstract: 291,003. Akt.-Ges. Brown, Boveri. et Cie. May 23, 1927, [Convention date]. Addition to 253,097. Vapour apparatus, arrangements of.-Relates to preventing back ignitions in metal vapour rectifiers by imparting to metal anode sheaths or grids potentials negative with respect to the corresponding anodes as described in the parent Specification, and consists in making the difference of potential between each anode and its grid dependent on load current. The anodes a<1> - - a<6> are energized from a set of secondary windings, one of which is shown at s<1>, of a main transformer having primary windings p<1>. The corresponding grids g<1> - - g<6> are energized with similar potentials from a second set of secondary windings such as s<2> either on the main or on a separate transformer. Between the two star points o<1>, o<2> is connected a small auxiliary rectifier z supplied by an auxiliary transformer, the primary p<2> of which is in series with the main primary p<1>. Under no load or light load conditions, the points o<1>, o<2> are at equal potential, the magnetizing current of the main transformer being insufficient to cause operation of the auxiliary rectifier, and consequently the grids have substantially the potentials of their associated anodes. Under load, however, the auxiliary rectifier z is rendered operative, and a D.C. voltage proportional to load current is interposed between the points o<1>, o<2> with the result that the grid potentials are rendered negative with respect to the corresponding anodes by amounts proportional to load current. The arrangement is so proportioned that above a predetermined value of load current, operation of the rectifier is interrupted either by the difference of potential between the anode carrying current and its grid becoming greater than the voltage drop in the rectifier resulting in the grid becoming negative with respect to the cathode k, or failure of the grid of the next anode in order of succession to attain a higher potential than the cathode in time for current to start in that anode. In order to prevent immediate restarting of the rectifier after cutting out, due to consequential cutting out of the auxiliary rectifier z controlling the grid potentials, a choking coil d is connected as shown so as to retard the rising of the grid potentials.

[Also in Group XVII] The emptying mouth 20, Fig. 5, of a suction cleaner filter bag 10 is secured e.g. by a hem 41 to a collapsible frame comprising a pair of main rails 25, Fig. 3, and a pair of aux-, iliary rails 27 hinged together at pins 30, 33, 35 so that when the bag mouth is fully open they lie substantially in a plane; the hinges 33 being such that that the auxiliary rails 27 hinge out of the plane of the main rails to allow the former to be brought together but at an angle to the collapsed main rails 25 to close the mouth. The hinges 33 are at 45 degrees to both pairs of rails so that in the closed position the auxiliary rails 27 are at right angles to the main rails 25, and the latter are secured together by a conventional clamp.
