Title: Improved linear polyesters
IPC: C08G69/44
Filed: 1963-06-07
Abstract: In the manufacture of linear polyesters by reacting a dialkyl ester of a dicarboxylic acid or carbonic acid with a 2:2:4:4-tetraalkyl-1:3-cyclobutanediol, there is used as catalyst an organo-tin compound or a stannous ester. Specified organic tin compounds are dialkyl tin oxides, dichlorides, dibromides, diiodides and dialkoxides; dialkyl dinonyl tins; and dialkyl tin esters of alkanoic and alkanedioic acids. Specified dicarboxylic acids are terephthalic, naphthalene dicarboxylic, 4:41-sulphonyldibenzoic, cyclo hexane-1:4-dicarboxylic and cycloic acid.  In addition to the cyclobutanediol, other glycols may be used, e.g. ethylene glycol, 1:6-hexanediol, neopentylene glycol, quinitol, poly (oxyalkylene glycols) and poly (thioalkyleneglycols). After the ester-interchange reaction between the dihydroxy compound and the dialkyl ester, the product is either subject to a melt phase polymerization or is first subjected to a melt phase polymerization to produce a prepolymer which is then solidified and ground and subjected to a solid phase polymerization, possibly after crystallization by treatment with acetone.  Examples describe the manufacture of polyesters by reacting (1) 2:2:4:4-tetramethyl - 1:3 - cyclobutanediol and dimethyl terephthalate; (2) 2:2:4:4 - tetramethyl - 1:3 - cyclobutanediol, dimethyl terephthalate and dimethyl azelate; (3) 2:2:4:4 - tetramethyl - 1:3 - cyclobutanediol and dimethyl azelate; (4) 2:2:4:4 - tetramethyl - 1:3-cyclobutanediol and dibutyl 4,41-sulphonyl dibenzoate; (5) 2:2:4:4 - tetramethyl - 1:3-cyclobutanediol and dimethyl trans-cyclohexane - 1:4 - dicarboxylate; (6) 2:4 - dimethyl-2:4 - diisopropyl - 1:3 - cyclobutanediol and dimethyl terephthalate; (7) 2:2:4:4 - tetramethyl - 1:3 - cyclobutanediol, 1:6 - hexanediol and dimethyl terephthalate; (8) 2:2:4:4-tetramethyl - 1:3 - cyclobutanediol, 1:4-cyclohexanedimethanol and dimethyl terephthalate; (9) 2:2:4:4 - tetramethyl - 1:3 - cyclobutanediol, polyoxytetramethylene glycol (M.W. 3100) and dimethyl terephthalate.

Title: An angle measuring or setting instrument
IPC: G01C1/02
Filed: 1957-07-18
Abstract: 818,628. Scale-reading devices; measuring angles. HENSOLDT & SOHNE OPTISCHEWERKE A. G., M. July 18, 1957 [Aug. 2, 1956; Nov. 16, 1956], No. 22742/57. Classes 97(1) and 97(2) An angle measuring or setting instrument includes a rotatable body carrying an annular coarse scale having double line dimensions and a scale reading device movable relative to the coarse scale, said scale reading device having optical elements for forming an image of at least one division of the coarse scale in a reading window, a fine scale mounted to appear in this window, means for moving the fine scale relative to the coarse scale image, and a further rotatable scale mounted to appear in the window and connected with the means for moving the fine scale. The optical dividing head shown comprises a spindle 1 which is rotatable by a handwheel 4 and carries on a cylindrical flange 20 a coarse degree scale 21 having double line divisions Fig. 3, the part of which immediately below an opening 22 is illuminated by rays from a lamp which are reflected by a semi-reflector 25 into an objective 24 and roof prisms 23. These optical elements together with two further prisms 26 and 27 (Fig. 4) and a lens 28 which receive the light reflected by scale and transmitted at 25 form a system which images the illuminated part of coarse scale 21 in a window 29. Adjacent this window is a plate 32 carrying a fine degree scale 39 having single line divisions, the plate 32 being linearly movable by rotating an eccentric 33, spring urged at 50 into constant engagement with a pin projecting from plate 32, and carrying a circular scale 37 which is divided into minutes and is readable against an index mark 38 (Fig. 1). By moving plate 32 until a graduation on scale 39 is enclosed by the image of a double graduation on scale 21, the rotation of spindle 1 is given in degrees and minutes. In a further form of dividing head, the coarse scale 21 is in two parts, one of which carries scale numbers and is rotatable relatively to spindle 1 and the whole optical system is mounted in a housing which can be rotated relatively to the spindle to facilitate zeroing. For the same purpose, the optical system may alternatively be fixedly mounted and include a prism which is slidable under the control of a rotatable cam to displace the image of the coarse scale. The two-part coarse scale 21 may be on spherical surfaces. In the optical turntable of Fig. 9, the table 90 is rotatable by a handwheel and has a coarse degree scale 96 on its underside. An image of this scale is projected on to a window 102 by lenses 99 and prisms 100, 101 so that this image appears superposed on a scale divided into 10 feet intervals carried by a glass plate 103 linearly movable by an eccentric having a peripheral scale divided into 5 inch intervals, so that the rotation of the table can be measured in degrees, minutes and seconds. Specification 643,590 is referred to.

An automatic, single - acting slack adjuster for brakes, comprises parts 4, 8 for attachment to brake rigging and a part 6, 7, 19 having a small axial play relative to part 4 and being screwthreaded on to part 8, and a oneway driving device for rotating part 6, 7, 19 comprising a clutch between part 6, 7, 19 and a driven member 15 rotatably mounted on part 6, 7, 19, the clutch being engaged by a compressed spring 14 disposed between shoulders 11, 13 on parts 4 and 6, 7, 19 respectively, wherein a sleeve 20 axially displaceable relative to part 4 and 6, 7, 19 has a shoulder 21 between shoulder 11 and spring 14 and normally transmits pressure of spring 14 to the clutch. On braking, force is transmitted from cylinder 3 via levers 1, 2 to part 4 and via shoulders 11, 21, spring 14, shoulder 13, part 6, 7, 19 to part 8. The spring 14 eventually yields and the force is then transmitted directly through shoulders 12, 13, the clutch which is formed by members 16, 19, 20, then being disengaged. If brake clearance is too large, a roller 25 in guide 26 rotates arm 24 which rotates member 15 before spring 14 has yielded, this rotation being transmitted via a pawl and ratchet (Fig. 3, not shown), to ring 16 and via the clutch to part 6, 7, 19. If the clearance is normal, the rotation of member 15 occurs after spring 14 has yielded and the clutch disengaged. An anti-friction bearing may be disposed between sleeve 20 and ring 16 (Fig. 4, not shown); and the ring 16 may be rotated via a pawl attached to a piston which is moved by compressed air after the brake cylinder piston has moved a predetermined distance.
