Convention date, Aug. 3, 1929. Addition to 343,860. [Class 56.] Rolling.-Relates to means for carrying out the method, described in the parent Specification, of replacing the impressing-roller of a machine for making figured plate glass in continuous strips. The apparatus comprises a pair of rollers c, d which form a strip w from a stream a of molten glass flowing from a spout p projecting from a tank furnace b, the upper roller c being suitably engraved to form the required pattern on the strip. Two impressing-rollers c, c<1> are mounted between endplates f provided with trunnions g which are carried by levers h. These levers are pivoted to the frame k of the machine and carry adjustable counterweights j. The plates f have notches l, l<1> to receive a latch bar m secured to the frame k. Abutment screws n serve as rests or supports for the levers h and allow the width of the pass between the two rollers c, d, and therefore the thickness of the glass strip formed by them, to be regulated. When the impressing-roller c is to replaced, a movable gate e is lowered to reduce the thickness of the stream of glass flowing through the spout. The latch bar m is then removed from the notches l<1>, the endplates f are lifted by means of the levers h, and the plates, and the rollers they support are rotated to bring the roller c<1> into the lowermost position. The plates f are then lowered and locked, and the roller c can be removed when desired.

Title: Improvements in or relating to the conversion of bhilawan shell liquid to a nonvesicating drying product for the manufacture of air-drying varnish compositions, enamels or the like
Filed: 1948-07-20
Abstract: A mixture of Bhilawan Shell liquid and turpentine is converted to a non-vesicating drying product suitable for dissolving in benzene and turpentine to make a lacquer, by treatment with nitric acid or with a mixture of saltpetre and hydrochloric acid.  In the example Bhilawan Shell liquid and turpentine are mixed and saltpetre and hydrochloric acid added alternately in small quantities.  The reaction mixture is cooled below 50-60 DEG  C.  The product is washed with hot water with kneading.  The final washing may be by water spray above a two-roll mixing roll, which is then used to press the product dry.  The product is dispersed in benzene under reflux, and diluted with turpentine.  Addition of a little acetone helps attainment of a homogeneous solution.  Thin coatings of the composition protect wood or paper against termites.  Oil-soluble dyes may be added to the compositions. Indian Specification 28,003 is referred to.

[Class 83 (i)] In a moulding-machine of the sand-projecting type with a sand container 11 above the table 13 on which the core-box or flask is placed, the bottom 14 of said container having openings through which the sand or the like is projected by compressed air into the box, the container is adjusted by a combination of pneumatic and hydraulic means on vertical pillars 24 at the sides of the box and clamped at adjusted position, e.g. by split sleeves 25, 26 and hand - operated screws 27. The container 11 is bolted to cylinders 31 which slide over the upper ends of the pillars 24 which are closed at 40. The upper ends of the cylinders 31 are connected by small ports 34 to reservoirs 35 containing oil and connected by piping 36, 37 and a hand-operated valve 60 to a compressed air supply. Another valve can supply air to an enlarged belt 41 of the container 11 which is closed by perforated metal strip 46, Fig. 4. A starter 59 controls a motor 58 which drives a paddle 49 for agitating the sand.

[Class 80 (iv).] In pneumatically-actuated guards for presses &c., the valve arrangement described in the parent Specification for controlling the supply of compressed air or other medium through pipe n to the pneumatic device o, q for operating the starting- lever p is modified by providing inlet and exhaust ball valves 3, 4 opened alternately by a spring- returned rocking lever 1, which is depressed by a nose 5 on the guard lever c when fully raised into the safety position by the pneumatic piston e, as shown in Fig. 3. If the spring 2 should break, the lever 1 is positively actuated on descent of the guard lever by a further nose 7 thereon. The cylinder o for the lever p is movable, the return spring therefor being supplemented or replaced by compressed air led directly from the main supply pipe h through a pipe n<1> to the upper side of the fixed differential piston q. The guard lever c is latched in its safety position by a pawl 8, which is tripped towards the end of the downstroke of the press ram by the rod r which opens the exhaust ball valve s for the guard-actuating cylinder f. To ensure that the lever p is released soon enough to avoid " repeats " in high-speed presses, the valve s may be respectively opened and closed early in the down and up strokes by positively limiting the motion of the rod r in a guide x, Fig. 1, and connecting it to the arm on the press ram by friction washers 9 allowing slip.

[Class 51 (ii).] In a furnace installation for melting copper of the kind comprising a continuous reverberatory furnace 10 the waste gases from which are passed through a preheating flue or tunnel 15 in countercurrent to the charges 32, the tunnel 15 is of annular form and the extent of preheating is regulated by byepassing a variable portion of the waste gases direct to the chimney 14, the two portions thus separated being reunited in the chimney and serving for heating a tubular recuperator 50 which supplies combustion air to the burner 12. The charges are delivered into the tunnel 15 at 18 and are carried in a clockwise direction by the travelling hearth 22 to the point 19 where a mechanically-operated member 41 is provided to transfer the preheated charges to the furnace 10. The proportion of waste gases passing direct to the stack is varied by a damper 48 controlling a passage 47, Fig. 3, which is formed by a partition 46 arranged transversely of the tunnel between the charging and discharging points 18, 19 and extending downwardly into close proximity to the hearth 22. The charging apparatus comprises a sliding member 23 operated by rack and pinion gearing 24, 25 to carry a charge, e.g. a pile of copper plates 29 into the tunnel 15 where they are elevated by mechanically-driven lifting bars 33, 34 to permit withdrawal of the charger and then lowered on to the hearth 22. An air-lock arrangement comprising a movable cover 28 and a sliding door 30 is provided to prevent escape of gases during charging. The hearth 22, which is formed with grooves 36, 37 to accommodate the charging and transfer members 23, 41, is fitted with a rack 57 engaged by a pinion 58 which is driven through reduction gearing 60, 61 by an electric motor 62, Fig. 1.

Abstract: 1,177,536. Hoses. CATERPILLAR TRACTOR CO. 1 May, 1967 [30 Aug., 1966], No. 19966/67. Heading F2P. [Also in Division B3] A method of making a reinforced elastomer, e.g. rubber, hose comprises the steps of forming a tubular core 11 by helically winding in overlapping relationship a laminated tape 12, composed of an open mesh fabric 13 sandwiched between uncured elastomer layers 14 and 15, on a mandrel 40, helically winding a plurality of wires 17 to form a first cylindrical wire ply on the core, covering the wire ply with an elastomer skin 18, helically winding a plurality of wires 20 on said skin to form a second cylindrical wire ply, the first and second plies being wound on opposite hands so as to cross one another, and subsequently vulcanizing the built-up hose. The tape is wound on an axiallymoving mandrel from a rotating winding head 42, Fig. 2 (not shown), mounting a tape storage reel 41 which is angularly-adjustable thereon. Further rotating winding heads 51 and 55 apply the wire plies, the individual wires of which are tensioned and given a helical set or curl by a nosepiece 65 threaded into a winding boss 62 carried by said heads, Fig. 6 (not shown). The layer of elastomer 18 is applied to the first wire ply by rollers 53 and 54 disposed axially between the wire-winding heads. A final elastomer ply 27 completes the hose. A nylon, tape may be wrapped around the hose prior to heating the hose assembly to vulcanize the same. The wire plies are wound at a helix angle of 5444<SP>1</SP>1. The laminated tape forming the tubular hose core is made by applying an uncured oil-resistant elastomer 33 and an uncured elastomer 30 to an open-mesh fabric 13 by two pairs of calendaring rollers 34, 35 and 31, 32, Fig. 3 (not shown). The wire plies are formed of high strength steel wire which may be brassplated.
