Title: Draw bench carriage
IPC: B21C1/28
Filed: 1947-07-10
Abstract: 626,521. Drawing. AETNA-STANDARD ENGINEERING CO. July 10, 1947, No. 18278. Convention date, Dec. 2, 1946. [Class 83 (iv)] A draw-bench carriage comprises a gripper head carrying gripping jaws and mounted on the frame structure for limited movement relative to the frame and resilient means interposed between said frame and gripper head for cushioning movement between the gripper head and the frame. The invention is described as applied to a selfpropelled carriage of the type described in Specification 619,683, but is stated to be suitable for use with a chain and cable operated carriage. A cylindrical gripper head G is slidably mounted in the bore 22 of the carriage frame F, and its forward and rearward movement limited by a retaining ring 27 and a shoulder 29 respectively, and rotary movement prevented by keys 26. The gripper head G is normally urged forward by four symmetricallydisposed springs 32, such that when the nose portions 36, 37 strike the die stand S the springs are compressed, preventing transmission of shocks to the carriage drive mechanism. The gripper head is provided with three sets of jaws, each comprising detachable jaw-members 50, clamped to holders 40, 41, supported and guided for sliding movement on faces 38, 39 of the gripper head member 23, Fig. 5. The three sets of jaws are simultaneously operated by means of a bar 51 extending transversely through slots 51<SP>1</SP> in the jaw holders. Rods 53, 54 connect the bar 51 to a yoke-member 56 connected to an operating rod 58. A spring 60 surrounds the rod 58 and tends to hold the jaw holders 40, 41 in the open or retracted position. In operation, as the carriage approaches the die stand S the rod 58 enters a sleeve 62 on the stand, and notch 63 makes a positive engagement with a spring-loaded plunger 64. As the carriage starts away on its drawing stroke the head G moves with the carriage F because of the engagement of a shoulder 28 on the member 23 with the retaining ring 27. The rod 58, engaged in the sleeve 62, and the yoke 56, remain stationary, and the relative movement between the jaw-holders 40, 41, and the member 23 causes the jaws to approach one another and grip the ends of the stock previously pushed through the die aperture. Further relative movement of the holders and the member 23 is then prevented and the rod 58 pulls out of the sleeve 62. Spring-loaded balls 52 on the face of the bar 51 compensate for slight differences in diameter of the pieces of stock being gripped by each pair of jaws. As the carriage continues to move away the drawing resistance maintains the grip of the jaws. The jaws may be manuallyoperated, a cam finger being caused to engage the yoke 56 and push it forward against the spring 60.

Title: A process for the production of high molecular weight polyethylene terephthalate
IPC: G03B7/0993
Filed: 1959-05-29
Abstract: In a process for the production of high molecular weight polyethylene terephthalate by transesterifying dimethyl terephthalate with ethylene glycol and subjecting the diethylene glycol terephthalate thus produced to condensation polymerization, magnesium ortho-antimonate is employed as a catalyst for the condensation polymerization.  The magnesium ortho-antimonate, which is preferably employed in an amount of from 0,01 to 0,1% by weight based on the weight of the dimethyl terephthalate, may be added to the reaction mixture before the transesterification reaction, but is preferably added when this reaction has been completed and after a relative viscosity of from 1,08 to 1,2 has been reached.  In Examples (1) dimethyl terephthalate and ethylene glycol are reacted in the presence of zinc acetate until the mixture reaches a temperature of 240 DEG C and a dispersion of magnesium ortho-anitmonate and titanium dioxide in ethylene glycol is added.  The temperature is gradually increased to 276 DEG C while maintaining a pressure of 0,1 mm. until the product has a relative viscosity of 1,630 to 1,650; (2) in a similar process the magnesium ortho-antimonate is added together with the zinc acetate before carrying out the trans-esterification reaction.  Specification 740,381 is referred to.

Abstract: 790,592. Printing on curved surfaces. SOC NAZIONALE PRODOTTI CHIMICI E FARMACEUTICI SOC. PER AZIONI. June 14. 1956 [July 8, 1955], No. 18487/56. Class 100(2)  A machine for printing in several colours on articles of non-porous plastic material of cylindrical or frusto-conical comprises rotatable means for supporting the articles arranged radially about a member rotatable about a vertical axis and intermittently up and down so as to be brought under and moved against printing members also arranged radially about said axis. The mandrels 4 are spaced at 45 degrees on a turret 3 carried on a hollow shaft 20 rotated intermittently through a Maltese Cross on like mechanim 22 driven by a motor M through a speed reducer R, which also rotates continuously a shaft 5 inside the shaft 20. A grooved portion of the shaft 5 carries a vertically slidable bevel gear 6 which rests on the turret and rotates the mandrels about their own axis through bevel gears 7. The shaft 5 also carries a helical gear 8 which drives gears 9 on shafts 10, carrying gears..1'1 which mesh with gears 12 on the shafts of printing rollers 2. The gear ratios are arranged to cause equal peripheral speeds of the printing rollers and mandrels. The shaft 20 is urged upwards by a spring 17 and lever 18,- and is held down by wheels 14 on extensions 13 of a plate 15 whose angular position is adjusted by a hand-wheel 16. When the mandrels are below the printing-rollers, grooves in the upper surface of the turret 3 are aligned with the wheels 14, so that the shaft 25 and the mandrels rise slightly to bring the articles into contact with the printing rollers.

Title: Improvements in colour charts
IPC: G01J3/52
Filed: 1967-04-21
Abstract: 1,131,172. Colour charts. VALSPAR CORP. April 21, 1967 [May 6, 1966], No.18499/67. Heading G2J. A colour chart comprises a sheet Fig. 1, having a group 1 of colour chips having equal white contents and arranged according to saturation, one chip 25' having a measured quantity of colourant, a second chip 19' having a portion (e.g. #) of its colourant replaced by black, a third chip 15' having a portion (e. g. ) of its colourant replaced by black, and so on, each of the chips having an amount of colourant plus black which is equal to the amount of colourant in chip 25'. A series of such groups of chips are arranged for different hues 1, 6, 10, 14, 18, 22, 28, 33, 37, corresponding to a portion of the colour circle, Fig. 3 (not shown). Since, with increasing black content, the optical differences between hues becomes less, a chip is provided at 7' (¥ replaced by black) for only every third hue line and also at 11' (¢ replaced by black), the latter also having a chip which is midway between hues (e.g. at hue 8 instead of either hue 6 or 10). Four such charts make up the complete colour circle (II, VII, XII, XVII) for one quantity of white which gives the light reflectance, which in Fig. 1 is 20. Thus each chip has its hue, saturation and light reflectance designated by a numeral e.g. 1-25'-20 is Phthalo blue, maximum saturation (i.e. no black content) and medium base (which has a controlled white content). Four similar charts are provided to form a complete colour circle at a number of different light reflectances so that a colour cylinder, Fig. 5 (not shown) is formed, e.g. circle (A), charts (I, VI, XI, XVI) has 1À5 times the colourant of circle (B) and deep base which has half the white content of the medium base in circle (B). Consequently the percentages of colourant and black content to white in circle (A) is about three times that in circle (B). Charts (C, D, E) are similarly formed with a greater white content. To economise in the use of pigments, cheaper oxides may be used as a replacement for part or all of the colourant plus black in some chips. Opening Op adjacent each colour chip enable comparison to be made with objects adjacent thereto. Formulae are given for reproducing any colour selected on the charts.
