Title: Process for producing polyethylene terephthalate
IPC: C08G63/78
Filed: 1963-01-09
Abstract: Polyethylene terephthalate is made by a continuous process in which bis-(2-hydroxyethyl) terephthalate or a low polymer thereof is continuously polycondensed in the presence of an added reactant adapted to react with the liberated ethylene glycol, the added reactant being a dicarboxylic acid or a lower dialky ester thereof. Specified reactants are terephthalic, isophthalic, succinic, adipic, glutaric, sebacic, xylidinic, dipheny-p,p1-dicarboxylic, naphthalene - 1,5 - dicarboxylic, naphthalene - 3,7 - dicarboxylic and durene-1,4-dicarboxylic acids and their dimethyl, diethyl, dipropyl and diisopropyl esters.  Preferably 0.05 to 1.0 mole of added reactant is used per mol. of bis-(2-hydroxyethyl) terephthalate.  The polyesterification process preferably comprises (1) continuously reacting dimethyl terephthalate and ethylene glycol in an ester interchange column from which the liberated methanol is removed; (2) feeding the resulting bis-(2-hydroxyethyl) terephthalate to a prepolymerization zone comprising vertically mounted heat-exchangers down which the ester-interchange product flows in the form of thin annular films and from which the liberated ethylene glycol is removed; (3) mixing a stream of the resulting prepolymer having a degree of polymerization of 8 to 18 with the added reactant and (4) feeding the mixture to a screw conveyer type final poly-condensation vessel from which the water or monohydric alcohol liberated by reaction between the added reactant and the liberated ethylene glycol is removed.

Abstract: 311,746. Thrissell Engineering Co., Ltd., (formerly Brecknell, Munro, & Rogers, Ltd.), and Dolman, H. J. Jan. 12, 1928. Coin action, multiple-coin; returning coin.-In coin-freed apparatus operated by a plurality oi coins, a detent is provided to retain the first inserted coin in a shoot in a position opposite a return opening which is blocked by an obturator, the obturator being removable, if desired, from its blocking position to return said coin, but, if the coin is not returned, the insertion of the last coin turns the detent to allow the retained coin to pass onward, whereupon the operation of the apparatus is effected or permitted. As applied to an apparatus, which is freed by the insertion of a shilling and two pennies, the shilling inserted in a shoot 1 rests on the nose 12, Fig. 1, of a detent 10 pivoted at 11 and projecting into the shoot, the tail 13 of the detent projecting into a shoot 2 for pennies. The shilling in its descent engages the tail 17 of a second detent 14 and withdraws its nose 16 from the shoot 2. The shilling rests on the detent 10 opposite a return opening blocked by an obturator 20 carried by a lever 18 pivoted at 19. The pennies can now pass down the shoot 2. If a penny is inserted before a shilling, it will be defected by the nose 16 of the second detent into a return shoot 8, Fig. 4. The first penny strikes the arm 29 of an inverted Y member 25 pivoted at 26 in the shoot 2 and is deflected thereby into a passage 9 leading to the shoot outlet 7, the member 25 being at the same time set to allow the second penny to pass straight through to the outlet 7. The second penny resets the switch member 25 and strikes the tail 13 of the detent 10 to release the shilling and allow it to pass through the shoot 1. Should the purchaser not have sufficient pennies, after the insertion. of a shilling, he presses a button connected with the end 24 of an arm 23 of the obturator 20 which is thereby withdrawn to allow the shilling to pass. through the return shoot. The obturator may be actuated by an attempt to move the delivery mechanism. When two coins only are used, the member 25 is dispensed with.

IPC: A61F2/58
Filed: 1924-01-17
Abstract: 231,264. Laherty, E. Jan. 17, 1924. Limbs, artificial. - An artificial hand is constructed so that the fingers and thumb can be closed and opened by turning the wrist relatively to the upper part of the forearm, and the whole hand can be rotated without operating the fingers by rotating the whole forearm relatively to the upper arm. As shown in Fig. 1 the hand 5 is connected to a leather forearm portion 12 which is secured to the arm of the wearer by lacing 13. A sleeve 14 shown in Fig. 6 surounds the wrist and is provided with a groove 15 in which is situated a ring 16 rigidly attached to aluminium strips 22 which are secured to a strap 23 surrounding the forearm near the elbow. The sleeve 14 and ring 16 carry pulleys 18, 20 round which pass the finger operating cords 29, 36 which are fastened at their ends to the rear potion of the sleeve 14. The fingers are actuated by rotating the wrist relatively to the upper part of the forearm which is surrounded by the strap 23. This movement causes the sleeve 14 to rotate while the ring 16 is held stationary by the strips 22 thereby causing relative movement between the pulleys 18, 20 and a displacement of the operating cords 29, 36. The hand is turned without actuating the fingers by rotating the whole forearm whereby no relative movement is obtained between the sleeve 14 and strap 23 and ring 16. Fig. 10 shows a modification in which two rings 16<1>, 16<11> are situated on the reduced ends of a sleeve 14' secured to the wrist. The rings are connected by strips 22<1> to the band 23<1> which encircles the upper part of the forearm. The finger actuating cord 41 passes over pulleys 42, 43 on the ring 16<1> and sleeve 14' and is attached at 44 to the ring 16<11>. The finger actuating mechanism for the form of hand shown in Fig. 1 is shown in Figs. 2 and 4. Two series of cords 27, 23 are attached to the upper and lower surfaces of the outer sections of the fingers and thumb as shown at 26, 34 in Fig. 4. The cords pass over two series of pulleys 25, 24 and are brought together at the points 28, 35 whence the single cords 29, 36 pass to the exterior of the hand as shown in Fig. 1. Springs 32 are included in the lengths of the actuating cords. In the form of hand shown in Fig. 10 the fingers are of the coiled spring type and are each actuated by a single cord. All the cords are brought together to form the single cord 41.
