Filed: 1970-10-16
Abstract: 1328968 Mobile passenger gangways BOOTHE AIRSIDE SERVICES Inc 16 Oct 1970 [16 Oct 1969] 49349/70 Heading B7J A mobile passenger transfer vehicle 10 comprises a passenger-carrying pod 17 mounted on guide posts 14, 15 for vertical movement relative thereto, each post having a respective screwthreaded shaft 25, 26 mounted thereon by means of a thrust bearing assembly 29, and an internally screw-threaded nut assembly 27 being mounted on each shaft and supporting a transverse bolster 19 of the pod 17 such that rotation of the respective shafts 25, 26 causes the nut assemblies to move up and down to raise and lower the pod. In a lowered position of pod 17, the support surface of each nut assembly 27 can be disengaged from the pod bolster 19, thus permitting the pod to rest on springs 88. Each thrust bearing assembly 29, Fig. 3, comprises bearings 59, 65 on opposite sides of an opening 51 in a bracket 31 fixed to the respective guide post 14, 15. Bearing 59 in retained by a plate 61 fixed to bracket 31 while bearing 65 rests on a resilient plate 63 and has a clearance with the respective shaft 25, 26. The shaft 25 or 26 is supported in the thrust bearing by a nut 70 supported on a washer 67, in turn supported by bearing 65. It can be seen that the clearance between the shaft and bearing 65 permits relative angular misalignment of the shaft and respective post over an angle A. Each nut assembly 27, Fig. 4, is prevented from rotating relative to the respective shaft 25 or 26 by side links 75 attached pivotally to a rigid member 74 of the assembly. The other ends of links 75 are pivoted to a forked link 77, in turn pivotally connected to a block 79 rigidly fixed to the respective bolster 19 which rests on the assembly. The bolster 19 lies on a polished sheet 81 forming a surface of a resilient bush 80. Thus rotation of shafts 25, 26 by motor M, via gearing 39, 37, 33 and 43, 41, 35 raises and lowers the nut assemblies 27 and hence the pod 17.

Abstract: 1322035 Spark gaps GENERAL ELECTRIC CO 20 Oct 1970 [24 Oct 1969] 49729/70 Heading H1D [Also in Division H2] Arc-terminating portions 7A, 8A of the electrodes 7, 8 of a spark gap assembly comprise a fusion-resistant material. The electrodes 7, 8 which may be of Cu are mounted in a chamber 8 formed in an insulating plate 3 and having arc-stretching teeth 18. The fusion-resistant material may be W, Mo, or the carbides thereof, or sintered composites of these metals with either Cu or Ag. Solid portions of these materials may be welded or brazed to the electrodes to form arc-terminating portions, or the materials may be flame sprayed over arcterminating portions of the electrodes. Four of the spark gap assemblies are stacked between insulating end plates to form a lightning arrester (Fig. 1, not shown) in which the spark gaps are connected in series and each gap is bridged by a preionizer and a resistor. The fusion-resistant material prevents sputtering of Cu from the electrodes and maintains the seals between the electrodes and the chamber, thus confining the arc to the interior of the chamber.

Title: Method of burning cement
IPC: F27B7/20
Filed: 1964-12-23
Abstract: Cement raw meal containing volatile constituents is burned to clinker in a rotary kiln by drying, preheating and partially calcining the raw meal outside the kiln in a stream of hot gases in which the particles of the meal are in suspension, this stream being composed in part of the products of combustion of fuel by air outside the kiln and in part of a fraction of the waste gases from the kiln, and discharging the remainder of the waste gases from the kiln to the atmosphere, thus controlling the proportion of volatile constituents in the clinker.  Preferably the discharged clinker is cooled by atmospheric air, part of which air then forms the air for combustion of the fuel outside the kiln, and part of which is fed to the kiln as secondary air for combustion therein; a part may also be discharged into the atmosphere.

Abstract: 533,570. Decorating surfaces. CURSON, F. B., and SANDERSON, J. C. July 14, 1939, No. 20593. [Class 93] A method of decorating the surface of wood or like porous material consists in applying a foil of a cellulose derivative to the surface to be decorated, applying on this foil a sheet of paper, close woven cotton, silk or other close fibred sheet material, and covering the latter with a further foil of a cellulose derivative, with the ornamentation located between the close fibred material and the last mentioned foil, union of the various layers being effected by the application of heat and pressure. The ornamentation may be preliminarily applied to the close fibred material, or to the last mentioned foil, e.g. by printing, and preferably the various layers are all submitted simultaneously to the heating and pressing operation. When the close fibred sheet extends over a part only of the area to be decorated, the two foils of cellulose derivative adhere together at the parts where the close fibred sheet does not extend. In an example, cellulose acetate foils of 1¢ thousandths of an inch in thickness are used, with cartridge printing paper in between, and a temperature of 80‹C. and a pressure of 400 lbs. square inch are applied for 15 minutes, the press and materials then being allowed to cool before removal of the materials.

[Also in Division D1] A stack of material laid-up on slats 30 by a laying-up machine 31 is lowered, by removal of the slats, on to a conveyer-belt 10 so that the forward end of the stack rests on a first portion 20 of a three-part cutting table 11. The conveyer belt is then moved bodily on wheels 13 to push the table over roller-conveyers 18, 21 and through an hydraulic press 12 until the end of the stack at the datum line 33 can be secured to the press by a clamping device 34; during this movement, links 23 slide into a table-supporting trolley 17 which in turn telescopes between the rollers 21. The conveyer-belt 10 is then returned bodily to its original position by its drive 15 while the belt itself is driven towards the press at the same speed. After the clamping device has been released, the portion of the stack lying on the second and third portions of the table is driven in stages through the press together with the table by the drive 15. The rest of the stack is fed through the press by repeated operation of the clamping device 34, drive 15 and conveyerbelt 10. The portion 20 of the table 11 may be provided with a supporting surface of low friction material, such as P.T.F.E. Frictional drag of the material over the second and third portions of the table may be avoided by arranging the clamping device to hold the stack above the level of the table and using rollers to hold the stack out of contact with those portions of the table.
