Title: Improvements in the manufacture and production of valuable condensation products from diolefines
IPC: C08F36/04
Filed: 1929-05-14
Abstract: 338,152. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 14, 1929. Caoutchouc, synthetic.-The polymerization of diolefines is effected with at least 30 per cent of an inorganic oxygen-containing acid or an organic derivative of such an acid, and no other substance influencing the reaction is supplied. Suitable agents are sulphuric acid, phosphoric acid. benzene sulphonic acid, toluene sulphonic acid, ptoluene sulphochloride, benzene sulphochloride, or the like. Products of varying character are produced according to the conditions of the reaction: thus, with low temperature, short time of reaction or low concentration of the acid, only or semi-solid products are generally obtained, while by longer or more energetic action harder products are produced. The process may be effected below 0‹ C. and elevated pressures may be em. ployed. The products may be used as adhesives, as additions to paints and lacquers, as additions in the manufacture of rubber-like products for the manufacture of artificial materials such as films, threads. foils, bands, and moulded articles. In the examples (1) butadiene is added slowly to 68 per cent aqueous sulphuric acid at -10‹ C., the mixture being stirred at -7‹ C. until the whole is soluble in water and contains no butadiene; the reaction mixture is' then poured on to ice and volatile matter is removed by steam; the brown mass remaining is dissolved in a solvent such as cyclohexane and washed with water and dilute sodium carbonate solution; after distilling off the solvent a viscous oil is left which distills at 150-300‹ C., leaving as residue a clear resin which softens at 60‹ C, and is soluble in many solvents such as benzene, toluene, xylene, chloroform, and carbon tetrachloride, (2) butadiene is heated in a pressure vessel with aqueous solution of benzene sulphonic acid for 20 hours at 100‹ C. ; on cooling the brown viscous product is treated with steam to remove volatile matter, the viscous dark oil remaining being washed with sodiumcarbonate solution and water and dissolved in ether; the ether is evaporated and a small proportion of an oil is distilled off at 25 m.m. pressure and up to 200‹ C. the residue being a resin similar to that obtained in the first example; (3) butadiene is heated with 89 per cent phosphoric acid, the rest of the process being similar to that of the previous example.

Title: Improvements in or relating to measuring gauges
IPC: G01B5/00
Filed: 1940-10-10
Abstract: 544,376. Linear dimension gauges. SHEFFIELD GAGE CORPORATION. Oct. 10, 1940, No. 15115. Convention date, Oct. 21, 1939. [Class 106 (ii)] Comprises an indicator operating block connected by spring strips so as to move parallel to a fixed block, a rotatable member mounted for axial adjustment in the movable block, and a work engaging member rotatably carried by the adjustable member having means for moving it axially as it is rotated. The base 10 carries a work support 11 and a pillar 12 along which may be traversed by rack and tooth gear 19, 20 a support 13 for the gauge parts which support may be clamped to the pillar by clamps 14, 15, 16. The support 13 houses stationary and movable blocks 25, 26 connected together at top and bottom by leaf springs 27, 28 relative movement between which is limited by a lug 54 on the movable block 26 engaging a gap 55 in the fixed block. This lug 54 is engaged by adjustable springs 56, 61 so that the block is moved down towards the work with a pre-determined force. The upper ends of the blocks are fixed to spring strips 29, 30 which are joined together and to a pointer 31 which engages between rubber buffers 63, 64 to prevent violent movements of the pointer. A ball 68<SP>1</SP> located in an inclined way 69 supported from the block 26 by a spring strip 70 engages the pointer to prevent vibration. The work engaging plunger 36 passes through a sleeve 34 screwed into the block 26 and has located at the protruding end double spring washers 46 located between a collar 45 and the end of the sleeve 34. A spring washer 43 surrounds the sleeve and engages between the shoulder 42 of the block and a nut 39 which is prevented from rotating by engagement with the surface of the block. A wheel 48 attached to the plunger carries a vertical pin 51 which engages a horizontal pin 52 on the sleeve by which the latter may be turned for rough adjustment. Fine adjustment may be made by turning the plunger only, a ball 50 engaging the slightly inclined end 49 of the sleeve. A lamp 74 energised from a power device 77 with switch 78 in the base supplies light through lenses 75 to throw a shadow of a bent over end 80 of the pointer on to a scale 73 which may be viewed through a dark glass 84 located in an opening 85 away from the influence of external light. In a modification the lamp is at the back of the support 13 and the light is passed through a longer path to give a greater movement of the shadow.

Title: Sheet delivery apparatus
IPC: B65H29/04
Filed: 1958-05-12
Abstract: 900,671. Delivering sheets. GOLDING, W. F. May 7, 1959 [May 12, 1958], No. 15168/58. Class 100 (1).  Sheet delivery apparatus for printing or like machines comprises two parallel endless chains, a plurality of gripper bars connected to and extending between the chains, a pair of sprocket wheels over which the chains pass, the diameter of the sprockets being such that they make one revolution for the passage therearound of each gripper bar, a device for opening the gripper jaws of each bar as it passes round the sprockets, and a member connected to the sprockets which travels in juxtaposition with the gripper bars as they pass around the sprockets and which ejects a sheet from between the gripper jaws when the latter are opened. Each gripper bar 6 has a number of resilient jaws 7 secured to the upper side thereof and sheets 9 are gripped between the jaws 7 and one edge of the bar 6. The jaws 7 are opened by levers 8 which are pivoted to the bar 6, depression of one end of a lever 8 causing the other end to rise and flex the corresponding jaw 7 upwards. A shaft 12 is eccentrically and rotatably mounted in bearings in the sprockets 3 and has a plurality of levers 11 secured thereto, each lever 11 carrying a pin 13 which is engageable with the free end of one of the levers 8. A lever 14 is also secured to the shaft 12 and carries a roller 15 which engages a cam track 16 secured to the machine frame. The sprockets 3 are so dimensioned that as each gripper bar passes around them the shaft 12 is adjacent thereto and the pins 13 are slightly spaced from the levers 8. As the roller 15 reaches a part 17 of the cam track 16 the shaft 12 is oscillated so that the pins 13 bear down on the ends of the levers 8 and cause the jaws 7 to release the sheet 9 held thereby which falls on to a stack beneath the sprockets 3. To help ejection of the sheet from the gripper bar a finger 26 is secured to one end of a bell-crank lever 21 pivoted at 22 to an arm 23 secured to the shaft 12. The other end of the bell-crank lever is connected by a link 25 to a lug 24 on the shaft 2 carrying the sprockets. As each gripper bar moves adjacent to the sprockets the finger 26 enters a recess 27 in the bar in front of the leading edge of the sheet 9. The oscillation of the shaft 12 to open the grippers causes the finger 26 to swing in a clockwise direction as seen in Fig. 1, so that it engages the leading edge of the sheet and pushes it off the gripper bar. The angular position of the cam track 16 in relation to the sprockets 3 is adjustable. Specifications 791,559 and 819,000 are referred to.

Filed: 1970-04-01
Abstract: 1283620 Making wire BRUNSWICK CORP 1 April 1970 [1 April 1969] 15531/70 Heading B3A A method of forming filaments includes the steps of sheathing a wire with a material differing from that of the wire, assembling a bundle of the sheathed wires and enclosing the bundle in a cladding strip, constricting the clad bundle, e.g. by drawing, to cause the wires in the bundle to have a filamentary diameter, and removing the sheathing and cladding material. As described, a strip 12 of Monel (Registered Trade Mark) metal is continuously longitudinally formed about a stainless steel wire 11 as shown in Fig. 2, the abutting edges 31, 32 of the strip being joined by a weld 33 extending less than fully through the thickness of the formed strip. The sheathed wire 11, 12 is then cleaned, annealed, cleaned and boraxed and reduced by cold drawing, these operations being repeated until the sheathed wire reaches its desired diameter. A plurality of the reduced sheathed wires 83 (Fig. 4b) are then fed from a rack 84 through a bushing device 92 to a cladding and welding station 96 where a strip 87 is formed around the bundle 93 in the same way as the sheath 12 is formed around the wire 11. The clad bundle 100 is then cleaned, annealed, cleaned and boraxed and reduced by cold drawing, these operations being repeated until the wires have a filamentary diameter. Alternatively, a plurality of the reduced clad bundles may be further reduced by passing them through the same apparatus again in place of the sheathed wires 83. The sheathing and cladding material is then removed, e.g. by leaching in nitric acid, to leave a tow of metallic filaments. In a modification (not shown) a plurality of unsheathed wires are assembled in a bundle and a lubricant is sprayed on to the bundle during cladding, the lubricant forming a matrix which separates the individual wires in the bundle.

[Also in Group II] In the drying of animal substances &c. in a drum containing heated agitator blades 8 are traversed by a heating agent when not in contact with the material but are sealed off from passage of the agent when in contact with the material. A horizontal drum 1 has an agitator shaft 2 with hollow spokes 5 and blades 8 heated bv steam via a pipe 4 and tube 3. Steam flows from the spokes 5 through openings 6 into a hollow ring 7 which carries the hollow blades '8 and then through tube 9 into the blades to outlet openings 10 and into a second hollow ring 11 which is divided into three compartments by walls 13. Condensate in the upper agitator blades is evacuated via a hole 14 and spokes 12 into pipe 15 but when the blades are in the material condensate fills the compartment 11 and prevents steam leaving the blades 8. As the spoke 12 is lifted again condensate discharges through hole 14 and steam can fall once more. The drum has a jacket 19 which may be supplied with steam for heating or condensation water or fresh cold water for cooling or other regulation of the temperature of the drum. Auxiliary blades attached to the agitator blades 8 may be used to assist transportation of the material when the drum is emptied by rotation of the shaft 2 in the reverse direction.
