Title: Plastic drain pipe and apparatus for forming and laying the same
IPC: E02F5/10
Filed: 1962-08-20
Abstract: 979,225. Laying drain pipes; non-metallic pipes. CATERPILLAR TRACTOR CO. Aug. 20, 1962 [Aug. 29, 1961], No. 31842/62. Heading F2P. [Also in Division A1]. A drain pipe comprises an elongated web 24 of pliable material formed into a substantially cylindrical shape with one edge overlapping the other and unsecured whereby only the presence of the surrounding earth will retain the said shape, and a second narrower elongated web 40 overlying the drain pipe and covering the overlapping edges thereof. As shown, the pipe-making apparatus 18 which is towed behind a mole drawn by a tractor includes a vertically disposed housing closed at the bottom thereof by a sole plate 23 and carrying a rotatable spool 25 from which is drawn a plastic ribbon 24 provided with perforations joined by slits to permit the passage of water through the wall of the tube formed by the ribbon. The ribbon extends over a guide roller 27 and passes downwardly between folding rollers 29 which fold the web along the longitudinal centre line thereof so that the ribbon passes in double thickness over a bar 30 disposed at an angle of 45 degrees and having a spiral formation with a guide member to assist in changing the course of the ribbon from vertical to horizontal. The sides of the ribbon pass on opposite sides of a finger 33 to be folded into tubular shape by a forming anvil 34 and a former plate 37. The overlapped longitudinal edges of the ribbon are reinforced by a perforated and slit web 40 drawn from a spool 41 and through a U-shaped guide 43. To retain the tubular form of the drain pipe the earth above the pipe is compacted by an element 46 attached to the device 18 by an adjustable draft chain 47. To insure against compression of the tube by the action of the element 46 a series of graduated frusto-conical members 48 within the tube and connected to the member 34 are drawn along by the device 18. The latter is connected to the mole by links which permit vertical and angular movement thereof.

Abstract: 952,474. Toothed gearing; clutch control. ZAHNRAEDERFABRIK RENK A.G. Sept. 16, 1960, No. 31896/60. Headings F2L and F2Q. In an epicyolio gear comprising a planet carrier 3 attached to a driving shaft 1, planets 6, fixed annulus 7 and driven sun gear 8, a multiple disc clutch K is interposed between the sun gear 8 and an output shaft 25, the clutch K being engaged below a predetermined speed and being adapted to disengage at and above the predetermined speed. A sleeve 13, having internal splines 14 and external splines 15, transmits the drive to an inner clutch disc carrier 17. The clutch is held engaged by fluid pressure applied through passages 23 to a piston 21. At the predetermined speed, an automatic speed-responsive device reduces the fluid pressure and the clutch becomes disengaged by springs 22. The annulus 7 is resiliently mounted in the housing by means of a cylindrical elastic element 9. The invention is applied to the transmission between a turbine and a generator.
Patent GB-856847-A (GB)
Title: Improvements in or relating to lubricating compositions
IPC: B21C23/32
Filed: 1958-10-07
Abstract: A lubricating composition, suitable for use in extruding, forging and other hot metalworking operations, comprises a solid lubricant (which is of lamellar structure and which does not fuse at the temperature of use) agglomerated with a combustible binder, together with a combustible fibrous support or reinforcement for the solid lubricant. The combustible support may comprise a corrugated or crinkled sheet of paper or cardboard or a light fabric of natural or synthetic fibres, such as cotton or nylon gauze, and a composition comprising the solid lubricant and the binder may form a coating thereon. Alternatively, the support may be a fibrous material such as paper pulp and may be mixed with the lubricant and binder.  Paper pulp may also be added to the coating composition applied to corrugated or crinkled paper or cardboard. Where paper is coated, a non-aqueous binder is preferably employed, for example a solution of a synthetic resin in an organic solvent; a solution of polystyrene in trichloroethylene is mentioned.  But where a fibrous support is mixed with the lubricant and binder, an aqueous solution of dextrin may be employed as the binder.  The solid lubricant may be flaked graphite. In addition to the lubricant and the binder, the mixture may contain a finely powdered organic substance which is combustible and non-abrasive (e.g. wood, cork, straw or carbon the latter being for example in the form of carbon black or graphite), a super-oxygenated metal oxide (e.g. manganese dioxide, lead dioxide or bismuth tetroxide) and a minor proportion of sodium silicate.  In an example, a lubricating composition consists of graphite flake, graphite powder, manganese dioxide, woodmeal, polystyrene powder and trichloroethylene and is applied as a coating to corrugated paper.

Patent GB-909269-A (GB)
Title: Metal-loaded molecular sieves
IPC: B01J20/18
Filed: 1959-09-23
Abstract: Zeolitic molecular sieves are treated with metallic Li, Na, K, Rb, Cs, Zn, Cd, Mg, Ca, Sr, or Ba, in liquid or, preferably, vapour form whereby the metal is adsorbed within the sieve structure.  Such treated sieves may be reacted with oxygen or nitrogen to convert the contained metal to oxide or nitride.  The zeolitic sieves concerned are the natural zeolites, chabazite, faujasite, erionite, mordenite, gmelinite and the calcium form of analcite and the zeolitic molecular sieves, designated A, D, L, R, S, T, X and Y set forth in Specifications 777,232, 777,233, 868,846, 880,702, 882,451, 909,264, 909,265 and 909,266 respectively.  Such zeolites are first heated to about 350 DEG C. to drive off substantially all of the contained water before contact with the metal.  According to Examples (1) sodium zeolite X pellets were contacted at 350 DEG C. with a helium stream to remove any contained water followed at 650 DEG C., by contact with a helium stream entraining the zinc vapour; the zeolite took up 1,2 weight per cent of zinc which was converted to oxide on contact with air.  (2) Zeolite X was, after dehydration, heated to 125 DEG C. and contacted with metallic sodium in a nitrogen atmosphere. (4) Sodium zeolite X pellets were mounted in a tube adjacent to a molybdenum boat containing metallic barium.  After removing all water the barium was heated to 600 DEG C. and the tube evacuated to 10-5mm. Hg. whereby the zeolite took up 3,5 weight per cent of barium which was converted to oxide and nitride on exposure to air.  The metal-loaded sieves may be employed as catalyst; for example a zinc or zinc oxide-loaded sieve may be employed for the synthesis of methanol, whilst an alkali metal-loaded sieve will selectively polymerize short chain olefines from an admixture with more complex branch chain olefines.  The metal loaded sieves may also be employed as getters for the removal of oxygen and other gases and as a means of adding metal to other chemical systems.  The oxidized barium loaded sieve is employed as a coating material for backing tube cathodes. Specification 841,812 also is referred to.

Abstract: 137,061. Great Northern Paper Co., (Assignees of Pope, C. E.). Jan. 31, 1917, [Convention date]. Guiding-mechanism; drying. - In a papermaking machine, means for loosening the paper web end from a surface with which it is in contact and for defecting it and directing it through the machine automatically, comprise air blast pipes 28, 29 by which the web is directed to the upper driers 18 as indicated in Fig. 3.

Fig. 6 shows an arrangement in which the pipe 28 is replaced by a rotary brush 45<1> co-operating with a nozzle 46. Doctors 23 direct the web end to the bottom driers 13, and doctors 24 attached to suction pipes 25 clean the driers.

Another ream is pushed on to section 8 and brake shoe 20 is engaged against roller 14 (Fig. 3). The material 15 is severed by blades 11, 12 (see also Figs. 5, 6, not shown) and elements 19 are released. Plates 9, 10 are raised and the table moves to the left. Table section 7<SP>1</SP> moves a little further to the left (Fig. 4) to transfer the ream and wrapper to further packing means (not shown) and then moves back to the right. Plates 9, 10 are adjustable. The machine may be operated by pneumatic or electromagnetic means.
