Title: An improved screwing die-head and a method for cutting screw-threads therewith
IPC: B23G1/22
Filed: 1968-06-28
Abstract: 1,211,899. Screwing die heads. GEORG. FISCHER A.G. 28 June, 1968 [30 June, 1967], No. 31133/68. Heading B3N. A die head for cutting a taper screw thread on the end of a pipe 1 comprises a rotatable body 15 carrying radially-disposed die members 24, a sleeve 2 having an external screw thread 12 of the same pitch as that to be formed on the pipe engaged with an internal screw thread 13a in a lead nut 13 secured to the body 15, a slipclutch 52 for disengageably coupling the sleeve 2 and body 15 for conjoint rotation, and a mandrel 4a, 4b which is axially displaceable in the sleeve 2 by means of interengaging screw threads 5, 50 and has an end which projects from the sleeve for insertion in the pipe 1 and is formed with inclined grooves 7 for radially displacing three wedges 8 located around the mandrel end into clamping engagement with the interior of the pipe 1 to secure the die head thereto. A die adjusting sleeve 20 rotatable with the body 15 has an inclined nose 27 engaging grooves 26 in the die member 24 and is in screw-threaded engagement with a thread 19 of greater pitch than the threads 5, 50 on a ring 17 which is connected to the sleeve 2 by a spigot screw 16 engaging a slot 40 so as not to rotaterelative to the sleeve but to be capable of limited axial movement resisted by a brake spring 36. The slip-clutch 52 couples a clutch ring 54 which is positively driven through a ratchet 51 when the body 15 is rotated in the thread-cutting direction to a coupling sleeve 55 which is adjustably secured to the sleeve 2 by a claw ring 53 and a nut 57 permitting adjustment of the thread diameter. In operation, the pipe 1 or the mandrel 4a, 4b is held fast and either the mandrel inserted in the pipe or the pipe fitted over the mandrel, and the body 1 is rotated manually by a hand crank or ratchet or is motor-driven through reversing gear engaged with a claw ring 56 on the body. Initial rotation of the body 15 is transmitted through the slipclutch 52 to rotate the sleeve 2 on the mandrel and tighten the wedges 8, but when the clamping torque attains a set value the clutch 52 slips and after one revolution of the body on the sleeve the ratchet 51 disengages from the clutch ring 54. The body 15 then advances along the sleeve 2, the die adjusting sleeve 20 being advanced more rapidly than the body by the thread 19 so that the die members 24 are progressively moved outwards to form the tapered thread. When the thread is complete the lead nut 13 abuts the end of the ring 17 which is axially displaced together with the die adjusting ring 20 to disengage the die members 24 from the thread.

A single layer of carrier threads may be attached to a single layer of reinforcement yarns or rovings, or may be between two such layers. The reinforcement layer may consist of strands or yarns of glass filaments, asbestos, or a high-melting-point polymer such as a superpolyamide. The carrier layer may consist of threads of cotton or other cellulosic material, filaments of a higher melting-point polymer such as a superpolyamide, or a polyester, or thin glass or asbestos strands or yarns. The fabric may be made by bringing the two layers together and subjecting to gentle pressure until bonded, the reinforcing system being preheated if a thermoplastic adhesive is used. The carrier layer may be calendered before bonding to the reinforcement layer.
Patent GB-856292-A (GB)
Title: Stable alkaline metal solutions containing carboxymethyl dextran
Inventor: NOVAK LEO J
IPC: B01J13/00
Filed: 1958-09-30
Abstract: A carboxymethyl ether of a dextran, or an alkali-metal, e.g sodium, salt of the ether, said ether containing an average of from 1,0 to 3,0 carboxymethyl groups per anhydroglucose unit of the dextran and having a molecular weight between 2,000 and that of native unhydrolysed, microbiologically produced dextran, is employed in stabilizing aqueous alkaline solutions of water-soluble metal salts which would normally precipitate a hydrous oxide (see Group III). The dextrans may be obtained from sucrose by enzyme synthesis in the presence or absence of bacteria.  For example, a sucrose-bearing medium may be inoculated with a suitable microorganism such as the leuconostoc mesenteroides or L. dextranicum types, or the microorganism culture may be filtered to obtain a filtrate containing the substantially pure enzyme, and this enzyme may then be added to the sucrose-bearing medium maintained at room temperature.  The dextran may be separated into various molecular weight fractions by fractional precipitation, and may be carboxymethylated to give the desired carboxymethyldextran.ALSO:Aqueous alkaline solutions of water-soluble metal salts, especially tervalent chromium salt, such as chromium sulphate, having a hydroxyl ion concentration between 0.14N and 5.8N, which would normally precipitate a hydrous oxide, are stabilized, thereby preventing such precipitation, by adding a carboxymethyl ether of dextran or an alkali metal, e.g. sodium, salt of the ether, said ether containing an average of from 1.0 to 3.0 carboxymethyl groups per anhydroglucose unit of the dextran, in an amount such that the equivalents ratio of the carboxymethyl ether of dextran anion to the metal cation is from 0.5 to 5.0.  The ether has a molecular weight between 2,000 and that of native, unhydrolysed, microbiologically produced dextran.  Other metal salts include the salts of beryllium, aluminium, scandium, lanthanides, actinides and the transition and post-transition metals of the long periods.

Title: Semi-automatic ornament gluing machine
IPC: A44C17/04
Filed: 1961-08-31
Abstract: 993,560. Mounting and setting gems. M. KORTICK. Aug. 31, 1961 [Aug. 31, 1960], No. 31311/61. Heading A3H. [Also in Division B8] An ornament setting machine comprises a hopper mounted on a base and intermittently rotated for feeding an ornament to a pick-up position means on the base for retaining a level of glue at a glue station means for picking up an ornament and for transferring it to the glue station for the deposit of glue on the bottom and moving the ornament to the assembly position. The ornaments are held in openings 12 and a rotary hopper plate 11 and a cylindrical wall slidable over the plate has a gap 18 through which an ornament pick up head reciprocates. A pawl 23 engaging a ratchet wheel 19 on the plate rotates the plate in steps of three openings. The pawl is connected to an arm 27 reciprocated by a pneumatic cylinder 46. The forward movement of the pawl is limited by a block 28 and rearward movement by a pawl 30, and for correct positioning an L-shaped block 32 engages the teeth. The pick up head is mounted on a block 63 connected to a bar 53, reciprocated by the rod 51 of a cylinder 50, over a shaft 56 which engages in three spaced grooves 57, 58 and 59 in the rod so that during rearward movement the rod 53 and the head dips as the shaft enters each groove, to pick up an ornament, to dip the ornament in the glue, and for an operator to attach a piece of jewellery to the ornament. The glue dipper 47 is positioned at one end of an arm 41 oscillating on a rod 43 linked to the arm 27 and reciprocating with it. The glue dipper angularly dips into a glue reservoir 37 supplied by an inverted bottle 38 and withdraws filled with the glue. In operation, the bar 53 moves rearwardly carrying the head and cylinder 65 through the gap 18. Simultaneously the rods 27 and 43 move forwardly rotating the hopper plate and submerging the dipper in the glue. The cylinder 65 picks up a rhinestone, dips the stone in the glue in the dipper and moves to a position where an operator presses the ornament in a setting in jewellery releasing the vacuum in the system and reversing the direction of the arm 53. The switch in the head which is operated by pressing the jewellery against the cylinder operates a solenoid valve 78 to cut off the vacuum supply, alters the flow to blowing momentarily and opens the solenoid valve 77 to exhaust. The pneumatic system is connected to a bleeder valve 82 connected to opposite ends of the cylinders and to a solenoid valve 77. The bleeder valve is controlled by the reciprocation of bar 53 and effects reversal of direction of motion of the cylinders. Alternatively the pieces of jewellery may be automatically fed beneath a multi-cylinder head and the ornaments may be automatically glued by dipping simultaneously into a series of glue dippers.

Abstract: 1,044,999. Lasers. WESTERN ELECTRIC CO. Inc. July 23, 1965 [July 27, 1964], No. 31464/65. Heading H3B. In an ion laser (i.e. a gas laser in which ions of the gas plasma are excited to a condition of population inversion by the use of substantial excitation current in the gas discharge path), continuous operation is obtained by providing two parallel gas paths between the cathode and the anode, one path serving for the gas discharge and the other for equalizing the gas pressure in the discharge path. The cathode 12 and anode 13 are located in enclosures 15, 16 which are connected by a discharge tube 11 and by an auxiliary tube 22 providing the discharge and pressure equalizing paths respectively. A water-cooling jacket 18 and a triggering winding 17 surround the discharge tube. For pressure balancing the internal diameter of tube 22 is larger than that of the discharge tube 11, and the tube 22 is sufficiently long to prevent a gaseous discharge from arising in the tube. For compactness and to permit relative thermal expansions the tube 22 may be of helical form. The discharge tube has Brewster windows 20, 21 and when used as an amplifier is provided with external or integral mirrors. Suitable gases are argon, vaporized mercury, other noble gases or various mixtures of such gases.
