Title: Process for the production of pigmented articles from fusible synthetic linear polymers
IPC: C08J3/22
Filed: 1952-11-21
Abstract: Improved pigmentation of highly polymerized linear polyesters and superpolyamides, is obtained by first incorporating substantial quantities of the pigment, e.g. up to 50 per cent, with a low molecular weight polymer, which may be of the same or different composition as the high polymer to be pigmented, and then mixing this strongly pigmented composition with a melt of linear high polymer in sufficient quantities to obtain the pigmentation required.  Pigments specified are TiO2, iron oxide, cadmium pigments, chromium pigments, carbon black; organic colouring matter may also be added, e.g. phthalocyanines, indigo dyes.  In examples (1) 500 gs. TiO2 are ball milled with 500 gs. caprolactam; 25 gs. aminocaproic acid are added and the mixture is polymerized in presence of nitrogen at 180 DEG  C. and then at 200-220 DEG  C. 0.25 Per cent of the product obtained is added to caprolactam which is then further polymerized and the product is spun into filaments in which the titanium dioxide is found to be uniformly distributed; (2) 1 per cent of the polymeric intermediate obtained as in (1) and containing 27.3 pts. iron oxide red, 13.6 pts. iron oxide yellow and 9.1 pts. carbon black is added to a melt of polymerized caprolactam; the melt on spinning gives brown coloured filaments; (3) 700 gs. caprolactam, 207 gs. red cadmium pigment, 10 gs. carbon black are mixed together and 27.4 gs. 30 per cent phthalocyanine added; the mixture is polymerized at 180 DEG C. while adding 20 gs. aminocaproic acid and then added to the amount of 9 per cent to a caprolactam melt.  (4) In this example the pigments employed are those described in Specification 520,199 and German Specification 565,426; (5) a mixture of caprolactam, TiO2 and aminocaproic acid is used to pigment polymerized polyhexamethylene adipate melt.

Title: Chuck assembly
IPC: H01J9/26
Filed: 1957-09-19
Abstract: 825,992. Vacuum chucks. CORNING GLASS WORKS. Sept. 19, 1957 [Oct. 1, 1956], No. 29546/57. Class 60. A chuck assembly comprises means actuated after an article 34 has been gripped by a vacuum chuck 23 to move the chuck and the article to a second position which is determined by the engagement of the article with a device 40. The article, such as the panel of a colour television tube which is to be sealed to its funnel held in another chuck, is provided with ribs 43, 44 for engagement respectively with blocks 41 and a notched slidable block 51 on a ring 40 carried on arms 46 secured to a hub 35 axially movable on a sleeve 13. The sleeve, at one end, is secured to a hollow shaft 12 connected to a source of vacuum and, at the other end, slidably receives a piston 22 carrying the vacuum chuck. A ring 27 is also secured to the sleeve and has radial arms 28 provided with posts 29 axially-movable against a spring 31. When vacuum is applied to the chuck, the panel is held against a sealing ring 24 and, since the vacuum also operates within the space between the shaft 12 and piston 22, moves the latter together with the chuck and panel to the right against a spring 21 until the ribs 43, 44 on the panel engage the block 41, 51 on the ring 40 ; rotation of the piston during its axial movement is prevented by a pin 36 cooperating with a slot 14 in the sleeve. The movement of the panel displaces the posts 29 which are then locked in position by screws 33 and serve to retain the panel in position when the hub 35, which is prevented from rotating by engagement of an arm 56 with a guide 58 and can be locked in position by a screw 57, is moved to the right with the ring 40 to permit clear access to the panel during its sealing to the funnel.
