Title: Manufacture of rollers for use in roller chains
IPC: B21L9/04
Filed: 1974-12-04
Abstract: 1447570 Making roller chain rollers CESKE ZAVODY MOTOCYKLOVE NARODNI PODNIK 4 Dec 1974 [22 Dec 1973] 52481/74 Heading B3A A machine for manufacturing rollers for roller chains from flat strip 54, Fig. 1, comprises a guide bed along which the strip is fed into the machine, a cut-out punch 16 and an associated cutting die 47 for removing a blank from the strip material, a broach 11 and an associated drawing die 48, a piercing tool 25, an upsetting tool 26 and a cutting tool 38 for acting on a blank to produce a finished roller, the cut-out punch, broach, cutting die and drawing die being coaxially mounted along a common axis, and the piercing, upsetting and cutting tools having a common axis spaced from and parallel to the common axis of the punch, broach and the dies. The strip is fed into a recess 45 of the machine where punches 16, controlled by a pressing plate 14, cut through the strip to form blanks which are shifted to the drawing die 48. Broaches 11 form the blanks into preformed roller cups 55. The piercing tools are moved downwards with a plate 15 and move the cups 55 into the upsetting dies 37 where they strike the cutting tools 38 as the plate 15 moves a plate 27 and the upsetting tools 26 downwards. The piercing tools, punches, broaches and upsetting tools are moved upwards following piercing of the cups. A feeder 52, Fig. 3, moves the cups between guides towards the piercing tools and finished rollers fall into a reservoir (not shown) and the cycle is repeated. The piercing tools are actuatable through action of a hammer on shock blocks 12 to cause contact of pulleys 13 with pulleys (21), Fig. 2 (not shown), mounted on pivotable forks (19). Such action causes lowering of a plate 23 relative to a body (18) provided in a recess (17) of the plate 15.

Abstract: 1287785 Test device MILES LABORATORIES Inc 30 Oct 1969 [8 Nov 1968] 53337/ 69 Heading B1X An indicator device to detect and/or determine pH, enzymes &c. comprises a carrier material in which is incorporated a chromogen. The carrier is preferably a transparent derivative of a natural polymer such as nitrocellulose, cellulose acetate &c., or a synthetic polymer such as polystyrene, polyethylene &c. To incorporate the chromogen in the carrier, a mixture of the carrier material, a solvent for the carrier material, such as acetone, methylethyl ketone &c., and the chromogen is allowed to solidify by evaporation of the solvent to form a film which may be self-supporting or bonded to a suitable base member of filter paper, wood, glass &c. Alternatively, the carrier material may be contacted with a mixture of the solvent and the chromogen, the solvent and chromogen allowed to penetrate at least the surface portion of the carrier material and evaporating the solvent from the carrier. Fillers such as cellulose, barium sulphate and alumina may be included in the device. The chromogen may be a diazonium salt of a dye, of which many are specified, and is preferably an insoluble polymeric diazonium salt of an aromatic polyamine such as orthodianisedine, benzedine &c., bound through an amide linkage to a cation exchange resin. Enzymes in solution may be detected and estimated by reaction with a substrate to liberate a coupling compound such as beta-naphthol, alpha-naphthol &c. which will react with the chromogen to form a coloured product. The substrate may be added separately to the enzyme solution or incorporated with the chromogen in the carrier. Many enzymes and substrates are specified. A pH indicator may be used as the chromogen and is preferably insoluble or prepared insoluble by the reaction of a polymeric diazonium salt of an aromatic polyamine bound through an amide linkage to a cation exchange resin and a coupling compound such as N,N-dimethyl aniline, the reaction of a diazonium salt of para-aminobenzyl cellulose and a coupling compound such as alphanaphthylamine, the reaction of a soluble compound having at least one free amino or phenolic group such as rosaniline and a polycarboxylic resin acyl halide, or the reaction of a diazonium salt and the reaction product of a polycarboxylic resin acyl halide and an aromatic compound having at least one free amino group. Urea, e.g. in blood, may be detected by incorporating in the carrier a urease enzyme which catalyses the release of ammonia from urea, a buffer, and a pH indicator which may be of the kind described above. Bilirubin or pyruvic acid may be detected and estimated using a suitable chromogen.

Heading C3P. Elastomeric copolymers are obtained by (a) polymerizing a mixture of a conjugated diolefin and a monovinylaromatic hydrocarbon in a hydrocarbon solvent, in an inert atmosphere, and in the presence of lithium or a mono- or polylithium hydrocarbon as catalyst to substantial completion of polymerization, and (b) additionally copolymerizing the resulting active copolymer at least once with a mixture of the same conjugated diolefin and monovinyl aromatic hydrocarbon as used in (a). Optionally, divinyl aromatic hydrocarbon monomers may be present in both or either stage. The products are probably block copolymers. The elastomers may be compounded with (i) a polyether of molecular weight 200-50,000, and in which the divalent aliphatic hydrocarbon radical of the fundamental molecule has 2-10 carbon atoms, or (ii) a solid paraffin having a melting point of 35- 160‹ C., or (iii) a polyethylene having a melt index of 1 to 1000, or (iv) a filler such as silica, or (v) a process oil or plasticizer. Monomers copolymerized in the examples are butadiene isoprene, styrene, p-methyl styrene, divinylbenzene and divinylnaphthalene, and the catalysts are n-butyl lithium and secbuty]- lithium. In comparative experiments, conventional conjugated diene-mono-vinyl aromatic random and block copolymers are prepared, including three-block copolymers obtained by coupling using either a difunctional lithium initiator or a dihaloalkane, or by sequential polymerization using monolithium hydrocarbons. In both the examples and the comparative experiments, mixtures of butadiene and isoprene are sometimes employed as the diolefin component.

The tool receiving devices are interconnected to form a chain which constitutes the magazine and which extends around sprockets (not shown) at each end of the bed, a tool holder 21 being connectable in each receiving device. The transfer mechanism 31 is mounted on the saddle 15 and includes a turntable member on which are slidably located a pair of tool holder gripping members 33. In operation, when tools are required to be changed the gripping members 33 engage a tool holder in the magazine and the tool mounting means 17 respectively, both tools being released from their respective position displaced as the gripping members are moved towards latch each other on the turntable member, the member is then rotated through 180 degrees and the gripping members moved away from each other to locate the new tool with its holder in the tool mounting means and the used tool in the vacant tool receiving device 24, the tool holders are subsequently clamped in their respective position. The tool holders are each provided with a coupling ring having axially extending teeth which engage corresponding teeth on the coupling ring on a tool mount means and a fluid actuated dovetail means engages the tool holder to effect engagement of the teeth and hence clamping of the tool holder in the required operative position. Similar means is provided to secure the tool holder in the magazine. To effect correct tool selection each tool is provided with identification means which co-operates with a reading head.
