Title: Blank for forming a container, and container formed from such blank
IPC: B65D75/08
Filed: 1952-04-23
Abstract: 728,141. Packages; paper and like bags. REYNOLDS METALS CO. April 23, 1952, No. 10242/52. Classes 94 (1) and 94 (2). A square-angled package or bag is formed by folding and heat-sealing a blank comprising two laminated sheets, each consisting of a layer of metal foil or other impervious material and a layer of heat-sealable material, the heatsealable layers being arranged face-to-face and the sheets being offset relatively to each other so that an exposed end margin of heat-sealable material is provided on each face of the blank. A similar blank may be formed by assembling two sheets of metal foil or other impervious material with an intermediate longer sheet of heat-sealable material. As shown in Figs. 6 and 9, two strips 49 of metal foil having a backing of thermoplastic material are cut from a roll 48 and superimposed to form a composite strip having exposed bands 61 and 64 of thermoplastic material on opposite faces and at opposite ends. Slits 50-53 are cut in one strip to form flaps which may be folded back during the formation of the package end closures. The composite strip is folded about a mandrel 69, Fig. 10, to form a tube having corner joints comprising turned-over end strips 71 and 73 covered on each side by the surfaces 61 and 64, and the metal foil heatsealed to the thermoplastic material except over the areas of the flaps. The tube and mandrel are then placed in a two-part casing 76, 77, Fig. 13, and the extremities of the bottom end of the tube are then pulled apart by fingers 78, 79, thus separating the flap 54 between the slits 50, 51 from the remainder of the tube so that it may be turned at right angles. A tool 81, Fig. 15, is then moved horizontally to turn down the front portion 82 of the tube and produce the folds shown in Fig. 17. The portion 84 is then folded down and heat-sealed to the surface of the portion 82 and after the triangular tabs 85, 86 have been folded inwardly, as shown in Fig. 20, the flap 54 is folded down and heat-sealed to complete the end closure. The package is then filled and its upper end folded in similar manner to produce triangular tabs 93, 94, Fig. 25, which are gripped by pliers 101, 102 while heat and pressure is applied by a tool 103. The tabs are then folded inwardly and the flap 55 between the slits 52, 53 folded down and heat-sealed to complete the package.

Title: Apparatus for balance-control in a weighing machine
IPC: G01G13/00
Filed: 1962-03-19
Abstract: 996, 573. Automatic feed weighers. CARL SCHENCK MASCHINENFABRIK G.m.b.H. March 19, 1962 [May 26, 1961], No. 10477/62. Headings G1N and G1W. Relates to an apparatus for controlling the equipoising of a weighing machine, for automatically weighing predetermined loads or weighing unknown loads, by controlling the feed from a hopper 21 to a weigh hopper 4 in the first case and by controlling the movement of a sliding weight in the second case, and wherein means including coils 13, 14 are provided for the production of a magnetic field to counteract deviation of a beam and whose strength varies exponentially with the deviation from the equipoised position, said means being controlled subject to the deviation which is due to the unbalance or differential moment of the beam. At the end of the beam 1 is a core 10 movable within stationary coils 11 of a differential transformer the output of which is fed to a control unit 24. The beam also carries cores 15, 16 movable within stationary coils 13,14 energized by the control unit so as to produce an exponentially increasing magnetic field counteracting the deviation of the beam as signalled by the differential transformer to the control unit. The coil 13 operates when the moment of the load is smaller than the counterbalancing moment and coil 14 operates when it is greater. It is stated that the control unit is capable of differentiating between a null position of the beam due to magnetically induced balance and one due to true balancing of the beam. The deviation can be limited by stop 25, 26 which may be electrical contacts. An eddy current brake 17, 18, 19 provided whose damping effect is controlled by the control unit 24. When weighing out a predetermined load the sliding weight is moved by a motor 7 to the appropriate position and with the weigh hopper empty, in response to the signal from the differential transformer, the control unit 24 starts the motor 22 on the feed hopper and feeding continues until the equipoise condition is attained. When weighing an unknown load in the hopper 4 the control unit operates the motor 7 to move the sliding weight to the balance position. It is also possible to provide a changing specified load per unit of time by timed displacement of the weight 5. The change in load may be increasing or decreasing e.g. when balance is obtained by emptying the hopper 4 by means of a worm 27 driven by a motor 28, the rate of discharge corresponding to the rate of movement of the sliding weight.

Patent GB-591037-A (GB)
Title: Application of finely divided contact materials
IPC: B01J8/32
Filed: 1945-04-26
Abstract: In a system wherein finely-divided solid contact material is contacted with a gas or vapour which tends to carry part of the finely-divided contact material from the system, e.g., in the fluidized catalytic cracking and conversion of hydrocarbons and the regeneration of catalysts, there is maintained in the system, mixed with the contact material, a second and different finely divided contact material which is, at least partly, in a finer state of subdivision.  The second material is carried out of the system to a greater extent than the first material, and hence loss of the first material is reduced.  The particle diameter of the first material may be predominantly above 20 microns, and that of the second material predominantly below 20 microns.  The second material may be of a friable nature so that fine particles are formed in the system.  For catalytic cracking a synthetic catalyst comprising silica and/or alumina and/or zirconia is used as the first material and a natural or treated clay or earth, e.g., activated fullers earth, as the second material.  A mixture of the two components in the same amount and ratio as that lost from the system is continuously or intermittently introduced.

A gas turbine is driven by. sulphur dioxide produced in the combustion chamber of the turbine, the sulphur dioxide thereby being cooled. The sulphur dioxide may be produced by burning sulphur, pyrites or " waste sludge" (a viscous acid material resulting from the purification of petroleum and lubricating oils by treatmentwith sulphuric acid). In the combustion of pyrites, a dust separator is inserted between the combustion chamber and the turbine. The -walls of the combustion chamber may be maintained at 300‹ C. by heat-exchange with molten sulphur to be burnt. The sulphur dioxide may be further cooled by passage from the gas turbine through a waste heat boiler. Alternatively or in addition, further cooling may be effected by passing the sulphur dioxide through a heat-exchanger for preheating the oxygen-containing gas for the combustion. The sulphur dioxide may then be catalytically convented into sulphuric acid directly or via the production of sulphur trioxide. Prior compression of the oxygen-containing gas may be effected in an axial, centrifugal or displacement type compressor. The compressor may have two stages. The gas turbine may be of the axial or radial flow type and may have four stages. Corrosion vulnerable surfaces may be of high chromium steel, nickel-chromium-cobalt alloy; or aluminium.
