Title: Improvements in or relating to apparatus for the manufacture of carpets
Inventor: WILKESMANN GUNTER
IPC: D03D39/06
Filed: 1954-12-06
Abstract: 776,949. Axminster looms. SCHEID, E. M., [trading as VORWERK & CO]. Dec. 6, 1955 [Dec. 6, 1954], No. 35290/54. Class 142 (2). A loom for weaving tufted carpets is fed with pile tufts by a conveyer chain 95 of the kind used in spool Axminster looms, but instead of tuft yam spools the chain transports rows of grippers which are manipulated by the usual transfer arms to deposit their tufts in the fabric and are returned to the chain empty, this action occurring as the chain passes round a pulley 104. A jacquard-controlled mechanism similar to that employed in gripper Axminster looms supplies the tufts, the grippers being detached from the chain to receive them at a guide pulley 108. To enable the loom or the tuft supplying mechanism to be stopped temporarily for replenishment or repair of yam without (for a time) stopping the other mechanism, the conveyer chain loops round travelling pulleys 109, 110, coupled together by a carriage 112 guided by rails 10. As shown, the tuft supplying mechanism has been stopped by a switch 163 operated by the carriage 112 at the end of its travel ; as weaving continues, the loop 114 shortens, thereby drawing the carriage to the left and forming a loop round the pulley 109 between guide rollers 101, 102. A switch 161 re-starts the tuft supplying mechanism as the carriage 112 passes it. Similarly, at the other end of the rails 10, a switch 63 stops the loom when the loop 114 of filled grippers is exhausted, and a switch 61 starts the loom when the tuft supplying mechanism begins functioning again ; under this condition, the tuft supplying mechanism operates at increased speed to build up a reserve of filled grippers, its speed being reduced as the carriage 112 passes a switch 50.

Title: Improvements in hektograph copying machines
IPC: B41L9/00
Filed: 1930-11-26
Abstract: 362,147. Coating webs. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Ditto, Inc. ; 2243, West Harrison Street, Chicago, U.S.A.) Nov. 26, 1930, No. 35644. [Class 140.] In hectograph copying-machines of the kind comprising a gelatine or like band passing over a flat bed, moisture is applied to the rear surface of the band so as to contact with the printing-surface when the band is rolled up and thereby maintain the gelatine in a pliable condition. In the form shown in Fig. 1, a roller 20 supported in brackets 22 fixed inside a water tank 24 contacts with the back of a gelatine band 16 passed over a bed 12 and rewinding on to a spindle 14. The tank 24 is slidably mounted on rails 26 and is moved into operative position by depressing a pedal 28 connected to a pivoted arm 32 connected by a link 48 to one arm 44 of a bell crank, the other arm 46 carrying a pivoted, spring-pressed catch 54 engaging a bar 56 on the tank. To retain the container 24 in the inoperative position, the final movement of the arm 32 is prevented by turning an arm 62 into a position where it prevents downward movement of the arm 44. In a modification shown in Fig. 3, a moistening-roller 120 is mounted in slots in bars fixed to a container 124 and dips in a shallow trough 170 fixed to and supplied from the container. When the container is moved into operative position, the roller 120 moves to the right relatively to the container so as to open, against spring pressure, a series of valves 174 carried by a bar 178 having arms engaging the trunnions of the roller 120 : water is thus admitted to the trough.

Patent GB-809409-A (GB)
Title: A process for the manufacture of linalool
IPC: C07C33/02
Filed: 1957-11-15
Abstract: Linalool is produced by reducing dehydrolinalool [3.7-dimethyl-octyn(1)-en(6)-ol(3)], dissolved in liquid ammonia by means of an alkali metal and an ammonium salt of an acid. Lithium, potassium or, preferably, sodium, may be used as the alkali metal. Any ammonium salt may be used, e.g. the sulphate, chloride, nitrate or acetate, but the salts of strong mineral acids, e.g. the sulphate, are preferred.  The dehydrolinalool used as starting material may be produced by the ethinylation of 6-methyl-heptene-(5)-one-(2) in liquid ammonia.  If desired, linalool may be made by condensing 6-methyl-hepten(5)-one(2) with acetylene in ammonia in the presence of an alkali-metal and reacting the resulting alkali metal alkoxide of dehydrolinalool in situ with an alkali metal and an ammonium salt. In the examples: (a) 3.7-dimethyl-octyn(1)-en(6)-ol(3) and ammonium sulphate are added to liquid ammonia; the ammonia is distilled off, water is added and linalool is separated from the resulting mixture; (b) 6 - methyl - hepten(5)-one(2) is added to a mixture obtained by bubbling acetylene through a solution of sodium in liquid ammonia; ammonium sulphate and sodium are added and linalool is separated from the resulting mixture; (c) 3,7 - dimethyl - octyn(1) - en(6) - ol(3), ammonium sulphate and sodium are added to liquid ammonia; the ammonia is distilled off and linalool is separated from the remaining mixture; (d) 6 - methyl - hepten(5) - one(2) is added to a solution obtained by bubbling acetylene through a solution of sodium in liquid ammonia; the ammonia is distilled off and ammonium chloride, ammonium sulphate and metallic sodium are added to the resulting mixture and linalool is separated; and (e) 6-methyl-hepten(5)-one(2) is added to a mixture obtained by bubbling acetylene through a solution of lithium in liquid ammonia; ammonium sulphate and metallic sodium are added and linalool is separated.
