Title: Shaping thermoplastic films
Inventor: BESTELINK PETRUS NORBERTUS
IPC: B29C71/02
Filed: 1959-10-14
Abstract: A continuous strip of crystalline oriented thermoplastic film is shaped, the shaped strip is heated to set it at a temperature below its melting point but at which internal stresses are relieved and, while being retained in the desired shape, it is then cooled to a temperature at which it has substantially no tendency to lose the shape imparted to it.  Oriented and previously heat-set polyethylene terephthalate film may be heat-set at from 150 DEG -230 DEG C., and oriented and previously heat-set polypropylene film may be heat-set at 100 DEG -170 DEG C.  Other specified film materials include nylon, polycarbonate and poly-3:3-bis-chloromethoxyoxacyclobutane. Apparatus, as <PICT:0887687/IV (a)/1> <PICT:0887687/IV (a)/2> <PICT:0887687/IV (a)/3> shown, suitable for making a film of the cross-section of Fig. 3, consists of a shaping die 2 (for details see Fig. 4) through which the strip of film 1 is led, followed by an electrically heated setting die 3 and a cooling die 4.  In a modification, the shaping and setting dies are integral and the latter is joined to the cooling die through a suitable heat insulator.  Specification 840,819 is referred to.

Abstract: 367,796. Knitting. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; Pawtucket, and Cloutier, A. N. ; Lonsdale, both in Rhode Island, U.S.A.) Nov. 19, 1930, No. 34816. Convention date, Nov. 30, 1929. [Class 74 (ii).] Striped effects in which two or more wrap threads 31 alternate in the same wale are produced on circular machines by circumferentially shifting a carrier disc 29 through eyes 30, 44 of which the wrap threads 31 pass. The carrier is mounted on a stub shaft 34 on which is a pin 39 projecting through an horizontal slot in a sleeve 38 and through an inclined slot 41 in a hub 42 carried by a disc 43. The carrier 29 is thus oscillated to change the warp threads over as the disc 43 moves up and down under control of a drum 11. The carrier 29 is also driven to rotate in time with the needle cylinder. When a cam 14 on the drum 11 comes under a lug 60 of a pivoted lever 58 arms 47, 56 pivoted at 51 are rocked to lift the disc 43. The carrier 29 can also be raised during heel and toe work &c. by a pattern-controlled lever 53. In a modification the disc carrier and its guide eyes always move round in time with the needle cylinder while flat pivoted levers carrying supplementary eyes are projected in and out as required to exchange the wrap threads. The drum 11 carries several sets of cams which operate, through intermediate connections, a series of jack-raising cams. The jacks when raised cause their corresponding needles to take in and knit the wrap stripe threads as described in Specification 300,605, [Class 74 (ii), Knitting &c.]. Specification 20101/09, [Class 74 (ii), Knitting &c.], also is referred to.

Title: Improvements in or relating to glass cutting machines
IPC: C03B33/04
Filed: 1955-12-06
Abstract: 788,965. Glass cutting. ABBEY, A. Dec. 6, 1955, No. 35030/55. Class 56. A glass cutting apparatus particularly for lenses, includes a table 16 on which the lens &c. 22 is held by a pad 23 on an arm 24, and a cutter 96 supported by an arm 97 pivoted about an axis 99. The shaft 14 carrying the table 16 is manually rotated by a handle 21 and the shaft 25 carrying the arm 24 is moved axially and angularly by a handle 49 which controls the axial movement by a cam 46 and the angular movement by a pin 45 and cam slot 37. A pin 59, staggered with respect to pin 45, coacts with an arm 61 pivoted at 62 and forming part of a yoke 66 of which the top portion 67 rotates about the bearing 68 of a shaft 73 to which is secured a head 84 on which the arm 97 is pivoted. Rotation of the shaft 73 is effected by the engagement of a roller 71 in a slot 70 in the vertical part of the yoke so that the pad arm 24 and the cutter are moved simultaneously over and away from the work table 16. Axial movement of the shaft 73 is derived from a lever 79 acting through a shaft 77, lever 76 and foot 75 acting on a roller 74 on the shaft 72 of the roller 71, the shaft 72 being carried, transversely, by the shaft 73. The movement of the cutter into engagement with the work is controlled by the engagement of an adjustable stop 105 on the head 84, with which the arm 97 engages under gravity, with a plate 55 carried by the arm 24. The pattern 101 is carried by the shaft 14 and the follower 102 by the yoke 66.
