Title: Improvements in and connected with the pickling, swilling, washing or other liquid treatment of metal rods, tubes, bars and the like
IPC: C23G3/04
Filed: 1934-11-08
Abstract: 447,120. Cleaning and pickling metals. TAYLOR & SONS, Ltd., Britonferry, Glamorgan, and TAYLOR, F. E., Moorlands, Port Talbot, [Executor of TAYLOR, G. A.] Nov. 8, 1934, No. 32130. [Class 82 (ii)] Metal rods, tubes, bars, &c. to be subjected to treatment with liquid, e.g. to be pickled, washed, or swilled, are placed in a carrier which is adapted to coact with devices in the treatment bath so that on lowering the carrier the mass of rods &c. is deformed, redistributed, or disturbed, so that the liquid has access to all parts of the mass and any gases produced can readily escape. In the form shown, three long narrow tanks, an acid tank a, a washing tank b, and a neutralizing tank c, are arranged side by side, each tank being provided with a number of spaced members e engaged with ribs or rails f on the sides of the bath and having their upper surfaces cut away to present a narrow W-formation. The carrier for the rods &c. comprises a number of cradles v approximately V-shaped in form suspended by arms w from a girder x which is provided with a bridle y for attachment to a crane hook z. The rods &c. are placed in the V-shaped cradles and the carrier is lowered into the bath, the rods being lifted out of the cradles and redistributed in the depressions of the W-shaped members e. The carrier is preferably jigged up and down so that the rods are repeatedly redistributed, being alternately collected on the cradles v and on the members e. The jigging in tanks a and b is effected by the provision at each end of the tanks of a pair of levers h joined at their ends by links s which, at their upper ends terminate in, or support, forked seatings t in which the girder x of the carrier can be seated. The levers are oscillated from a shaft o by crank mechanism. A carrier is first jigged in the acid tank a and then transferred to the seatings t above the washing tank b, a fresh carrier being placed on the seatings t above the tank a. After treatment in the tank b the carrier is transferred to the neutralizing tank c. The cradles v have flat bottoms v<2> so that the carrier can be placed on the ground for loading, unloading, &c. The form of the cradles and of the members e may be varied, for example, the cradles, instead of being V-shaped, may be semicircular, parabolic, &c.

Title: Improvements in and relating to reinforced concrete roofs and the like and to a process of manufacture of same
IPC: E04B7/10
Filed: 1937-11-23
Abstract: 505,787. Roofs. BARONI, G. Nov. 23, 1937, No. 32194. Convention date, Nov. 23, 1936. [Class 20 (iv)] A reinforced-concrete roof comprises one or more sloping ruled-surface parts of hyperbolic paraboloid or conoid form which are reinforced by metal bars or wires 4 arranged under tension along the direction of length of the generating lines of the surface and also by further metallic elements. The latter elements may consist of metal bars or wires in the form of a network 6, these bars or wires being disposed at an angleto the bars or wires 4. The roof shown in Fig. 1 comprises a vaulting-cross B and peripheral beams 2, and each of the parts of the roof between the arms of the cross B is in the form of a hyperbolic paraboloid. The bars or wires 4 are stretched between appropriate points on the beams 2 and arms of the cross -B, along generating lines of the surface, being disposed at varying inclinations to the horizontal as necessitated by the form of the surface. These bars or wires 4 pass through holes 16 in the outer of two shuttering-boards 11, 12 used for casting a marginal beam, as shown in Fig. 3, and are tensioned by screws 5. The roof may be cast by plastering concrete from beneath the metal lattice work so that it passes therethrough to the desired thickness; alternatively, the casting may be effected by means of a jet disposed above the latticework. If desired, the roof may be first cast to a certain thickness, and, when this has set, a second concrete layer, which has its own metallic reinforcing structure, is cast thereon. In cases where the necessary amount of metal reinforcement cannot be obtained with a single layer of bars or wires 4 and associated network 6, a second layer of such bars or wires and network may be disposed above the first. The bars or wires 4 and /or the network 6 may be supported at intervals by devices arranged above or beneath the roof. The marginal beams 2 and cross B may be cast prior to, or simultaneously with, the roof covering. The marginal beams 2 are of triangular shape in elevation, being either of solid construction or of open-frame form comprising spaced struts 23, an upper member 24, and a lower tie 25 as shown in Fig. 6. These beams are reinforced by longitudinal bars or wires 20, Fig. 3, and vertical bars or wires suspended from the bars or wires 4, and, when the beams are of open-frame form, the vertical reinforcing-members are disposed in the spaced struts 23. The roof may be supported by a pillar at each corner or in the middle of each marginal beam. The Specification as open to inspection under Sect. 91 states that the hyperbolic paraboloid or conoid forms of the roof are optional. This subject-matter does not appear in the Specification as accepted.

Patent GB-869300-A (GB)
Title: Production of filamentary material from substantially straightchain linear polyethylenes
IPC: D01F6/04
Filed: 1957-10-18
Abstract: A solution of a substantially straight-chain linear polyethylene in a volatile solvent is dryspun to form filaments, the solution being maintained under super-atmospheric pressure at a temperature which is at least as high as is necessary to ensure that the polyethylene is in solution in the solvent and which is above the boiling point of the solvent at normal atmospheric pressure.  Preferably the rate of extrusion through the spinning jet is such that the pressure drop through the jet is in excess of the vapour pressure of the solution at the spinning temperature plus the pressure of any dissolved gas, the pressure on the discharge side of the jet being atmospheric.  The preferred solvents are aliphatic and cycloaliphatic hydrocarbons, particularly cyclohexane.  In the example, a 5% solution of polyethylene prepared by passing ethylene into a mixture of cyclohexane and chromium oxide catalyst, supported on silica-alumina, as described in Specification 790,195 is filtered, concentrated to 23% by passage through an agitated flasher operated at 25 p.s.i. gauge pressure and 150 DEG C., and pumped at 145 DEG C. and 360 p.s.i.g. through a spinning jet into a spinning cabinet supplied with air at 133 DEG C. to form filaments.

Abstract: 1302506 Cathode-ray tube displays ISE ELECTRONICS CORP 14 July 1971 [16 July 1970] 32920/71 Heading H4T Patterns, e.g., alpha-numeric characters, are displayed on a cathode-ray tube 12 (Fig. 1) by selective control of an apertured matrix electrode 12c, 12d positioned in the electron stream from the cathode 12a and may be selectively enlarged or reduced by controlling the voltages on the focusing electrode 12f and the grid electrode 12e uniformity of display brightness being maintained when the size is changed by controlling the voltage on the first grid electrode 12b. The position of each character is determined by stepped voltage waveforms supplied to the deflection windings 12g and the spacing between adjacent characters and between successive lines of characters is varied in accordance with the change in character size to prevent overlapping (Fig. 7). The system is controlled by signals from, (e.g. a computer) memory 1 the decoded output of which selects a particular pattern memory 4 such as the diode matrix 4 (Fig. 2) concerned in the display of the numeral "2" (Fig. 3) and also provides the various electrode voltages for the tube 12 to effect the controls referred to above. The diode matrix 4 is connected to the beam controlling aperture matrix electrodes 12c, 12d as shown at 14 (Fig. 2) and "scanned" by successive pulses from counter 5 applied to inputs 17-21 to provide the condition required to allow the electron stream to pass through the appropriate intersections of the X and Y elements of the matrix which are required to produce the display, in this case the numeral "2". The D/A converters 7, 8 and 9 may be replaced by circuits which produce the required electrode voltages by including a single D/A converter in the common input from decoder 3 (Fig. 8, not shown). The whole system is controlled by clock pulse generator 6.

Title: A process for the simultaneous production of methane ammonia and alkali or alkaline earth carbonate or hydrate
IPC: C01D7/08
Filed: 1931-12-01
Abstract: In the manufacture of ammonia and alkali or alkaline-earth carbonate or hydrate by hydrolysis of the material formed by the action of nitrogen on a mixture of carbonaceous material and an alkali or alkaline-earth compound, the permanent gases obtained in the hydrolysis are fractionally distilled to obtain methane, e.g. using Linde's process.  The methane may be converted to liquid hydrocarbon by passing it through a porcelain tube heated to 1190 DEG  C.  By using steam for the hydrolysis, the alkali or alkaline-earth product is obtained in the form of hydrate.  In the example, briquettes of 3 cm. diameter containing 5 parts of soda and 5 of coke to 1 part of common salt are heated for 4\ba1/2\be hours to 950 DEG  C., treated with nitrogen for two hours while maintained at this temperature, and then cooled to 450 DEG  C. and treated with steam.  The methane is separated and rectified at the temperature of liquid air.
