Title: Web Winding Apparatus.
Inventor: HELLMANS ALBERT JOSEPH
IPC: H04Q3/00
Filed: 1967-02-02
Abstract: 1,154,662. Winding webs. GEVAERT-AGFA N.V. 6 Dec., 1967 [2 Feb., 1967], No. 5168/67. Heading B8R. In a turret web winding machine (Fig. 1a), cut-off and transfer apparatus comprises a web guide 54, 55, which in an operative position, Fig. 4, defines a pathway 91 partly around a core 67, a cutter 35 for severing the running web 70 near one end of the guide, and air blast means 34 for guiding the leading end of the severed web into the pathway 91 and on to the core 67. Fig. 6 shows the position of the apparatus after the leading end of the severed web has been partly wound on to a new core 67, but is also the position of the apparatus prior to cut-off and transfer. Two arcuate guide plates 54 and 55 are hinged together to form the web guide, and are mounted between a pair of pivoted arms 46. The plates 54 and 55 subtend angles of 180 and 90 degrees respectively. The sawtooth cutter 35 and the air blast means 34 which comprises a conduit provided with rows of perforations (73, 74, Figs. 7a and 7b), are mounted on a pair of arms 32 pivotally mounted on stub shafts between a pair of pivoted arms 18. The arms 18 carry a roller 28 having a resilient surface 29 for pressing the running web 70 against the core 67, and a further roller 27 for deflecting the web path closely past the transverse edge 110 of the plate 54. In operation, the arms 46 are pivoted from the position shown in (Fig. 1b or Fig. 6 to the position shown in (Fig. 3) by pneumatic cylinder 51. Thereafter, plate 55 is pivoted by pneumatic cylinder 59 to the position shown in Fig. 4. At the same time, pneumatic cylinder 24 pivots arms 18 in an anti-clockwise direction bringing the pressure roller 28 into contact with the moving web 70 and core 67. This is followed by a pair of pneumatic cylinders 36 pivoting the arms 32 in an anticlockwise direction, so that the cutter 35 severs the web and the air blast means 34 blows the leading end of the severed web into the pathway 91. After a short delay, a reverse sequence of the above-described operations takes place. Additional air blast means 127 may be provided at the entry end of the web guide plate 54, Fig. 6. Loss of air transversely from the web-guide is partly prevented by annular seals (94 to 97, Fig. 2). Operation of the apparatus may be controlled automatically by sensing means responsive to the diameter of the roll being wound, or detecting a few meters upstream of the apparatus the arrival of a splice in the web, which is an appropriate place for cut-off and transfer. The sequence of operations of the apparatus is controlled by micro-switches (not illustrated) mounted on the apparatus and detecting the completion of movement of the various pivoted arms.

Patent GB-636333-A (GB)
Title: Improvements in and relating to the manufacture of aromatic amino carboxylic acids
Filed: 1947-02-22
Abstract: Alkali metal salts of 4-amino-2-hydroxy benzoic acid are prepared by the reaction of carbon dioxide with m-aminophenol in the presence of an alkali metal hydroxide, carbonate or p  bicarbonate and water, preferably at a temperature of over 100 DEG  C. Conveniently, the reaction may be carried out by heating m-amino phenol with the alkali-metal compound and solid carbon dioxide in an autoclave at about 130 DEG  C.  The free acid may be liberated from the reaction product by adding dilute hydrochloric acid until just acid to litmus, or by dissolving in an excess of hydrochloric acid to form the aminoacid hydrochloride which is separated and dried and treated with an equivalent quantity of an alkali metal bicarbonate and just sufficient water to dissolve the alkali metal chloride formed.  In examples: (1) m-aminophenol, potassium bicarbonate, solid carbon dioxide and water are heated in an autoclave and the reaction product is neutralized with hydrochloric acid to give 4-amino-2-hydroxy benzoic acid; (2) sodium bicarbonate is used in place of potassium bicarbonate in (1) and (3), the process (1) is repeated using gaseous carbon dioxide in place of solid carbon dioxide and the product is separated by means of the aminoacid hydrochloride.  Reference has been directed by the Comptroller to Berichte der Deutschen Chemischen Gesellschaft (Referat), Volume 23 (1890), page 313.

Patent GB-1097134-A (GB)
Title: Oxidation of olefins
IPC: C07D295/027
Filed: 1965-02-11
Abstract: Oxygenated organic compounds are produced by oxidizing olefin-containing feedstocks with molecular oxygen in a solvent which is oxidatively and thermally stable, chemically indifferent, free-radical resistant and high boiling, under temperatures and pressures sufficient to cause the reaction to proceed in the liquid phase, and recovering oxygenated products by a process comprising a considerable number of steps which is not capable of satisfactory abridgment.  The Specification relates particularly to the production of propylene oxide and acetic acid in various yields relative to each other by oxidation of propylene, preferred solvents being fully esterified polyacyl esters of polyols, such as propylene glycol diacetate. Other oxidation products such as acetaldehyde, methyl formate and propylene glycol are separated during the recovery process.

Title: A time switch with switching tappets
IPC: H01H43/00
Filed: 1962-02-16
Abstract: 937,478. Time switches. LICENTIA PATENT - VERWALTUNGSG.m.b.H. Feb. 16, 1962 [Feb. 24, 1961], No. 6041/62. Class 38 (5). A time switch comprises a 24-hour dial 1 carrying two switch-actuating tappets, such as 3, which are each circumferentially adjustable and guided in a groove 14 by the end 8 of a screw 15. Each tappet has a pin 41 on which is mounted a spring 7 exerting a torque to cause the tappet to grip the dial 1 at the points 5 and 6. The dial rotates in the direction of the arrow and hence the reaction on the part 9 of a tappet when it operates the switch (not shown) acts in the same sense as spring 7, thereby increasing the grip of the tappet on the dial 1. A radial setting lever (Fig. 3, not shown) has two fingers 11 and 12 thereon which do not normally lie in the path of the tappets but the setting lever may be rotated and then displaced axially against a spring to bring the fingers into the position shown. Further rotation of the setting lever now causes either finger 11 or finger 12 to engage the tappet. Finger 11 acts to produce a moment opposed to that of spring 7 and thus releases the grip so that the tappet may be moved around the dial 1 in one direction, while finger 12 acts to slide the tappet in the other direction since its position radially inward does not produce a gripping reaction.
