Title: Improvements in containers of paper or like sheet material and a method and apparatus for their production
IPC: B31B3/28
Filed: 1938-01-12
Abstract: 499,611. Making paper &c. containers. FRAZER, G. E. Jan. 12, 1938, No. 1027. [Classes 66 and 94 (ii)] A paper &c. container, Fig. 2, is formed from sheet material lapped upon itself to form a cylindrical &c. sleeve with a stem 34 and bottom portion 8 formed at one end of the sleeve. Paper &c. in web form 10 is cut on the bias at 19 by rolls 11 carrying a blade 12, the severed blank being fed by tapes 14 to a rotatable mandrel 16 and formed into a tube 18 preferably of two or more thicknesses. One end 20 of the tube 18 overhangs the mandrel end 22, which is shaped with a convex surface 23, and a blade 28, carried by an arm 27, spring-biassed about a pivot 26, is moved to cause the end portion 20 of the tube to become partially twisted into the stem or handle portion 34. The rack-and-pinion mechanism operating the arm 27 also operates, through the pinion 38, a shaft 37 which next brings into operation spring - biassed tapered rolls 40, which consolidate the stem portion 34 of the container, and concave-surface rollers 46 which press the bottom 8 of the container to the shaft 23 of the mandrel end 22. The rod 24, carrying the mandrel end 22, is now moved through the mandrel to strip the formed container therefrom. which is filled with a confection and frozen.

J., Sunbree, Evington Lane, Old Evington, all in Leicester. Jan. 14, 1933, Nos. 1275, 6997, and 17588. [Class 74 (ii).] The heel of a stocking &c. knitted on a circular machine in flat selvedged form is followed or preceded by one or more courses 9 or 9a of a yarn which is afterwards cut at 8. A square type of heel is produced by trimming the corner 12, seaming &c. The fabric is made by reciprocation on a group 13 of needles with short butts, comprising rather less than half the total number. This group is flanked by two small groups 14, 15 of needles with medium butts. The instep needles 16 and the group 14 are raised on the last complete revolution prior to reciprocation, while the first turn in the opposite direction serves to raise the group 15. The cams 17, 18 for raising the groups 14, 15 may be obliquely pivoted at 23 to blocks 24. A pattern-controlled lever 26 connected by links 29, 40, 36 puts in the cams 17, 18 and simultaneously takes the pickers 34, 35 out of action.

In a double friction clutch for use in forward and reverse transmission paths of industrial motor vehicles and comprising upper and lower spring-applied pressure plates 9, 10 and associated friction discs 6 all in a common housing 12 bolted to a flywheel 14, the clutches being disengaged by two sets of release levers 1, 2 rocked by a common pedal-operated disengagement bearing (not shown), a locking ring 3 which permits selective locking of one or other or both clutches in the disengaged position is supported on rollers 23 on the housing and is provided with cam teeth 13 engaged by a latching lever 8 and by one or more shift levers 4 operated by full depression of a release lever 1 of one of the clutches to rotate the ring and to present castellations 33 thereon under either or both sets of lugs 31 or 32 on levers 1 and 2 respectively, to lock the respective clutch in the disengaged position. The locking ring may be arranged so that both clutches may be locked in the disengaged position (not further described). The lever 1 acts on lever 4 when the levers 1 and 2 are depressed to disengage the clutches, to rotate the locking ring by an amount dependent on the depression of the lever 1, full depression of the lever 1 permitting the latching lever 8 to pass over one tooth 13 and, on releasing levers 1 and 2 maintain the locking ring in its new position so that the previously disengaged clutch is now engaged and vice versa. Partial depression of levers 1 and 2 rotates the ring 3, but on releasing these levers, the latching lever 8 returns the ring to its previous position.

Title: Improvements in apparatus for coiling textile slivers and the like
Inventor: WARRINGTON CLIFFORD
IPC: B65H54/80
Filed: 1961-01-13
Abstract: 929,507. Coiling slivers. TWEEDALES & SMALLEY Ltd. April 2, 1962 [Jan. 13, 1961], No. 1615/61. Class 120 (3). Textile sliver coiling apparatus, of the kind comprising two coiling stations and a single coiler head swingable between the two stations, has adjacent to the underside of the coiler head and in a position located intermediate its angular traverse, severing means co-operating with an undersurface of the coiler element so that a sliver extending from a filled can is nipped and ruptured between the severing means and the under surface during the angular traverse. The sliver enters the coiler head through two driven rolls 23, 24, and passes through a coiler tube 27, mounted on a rotating tube wheel 16, into one of the rotating cans. The severing means consists of two rollers 32, side by side, which may be fluted and which are continually rotated, through a gear mechanism by a shaft 11 which also drives the rolls 23, 24 and the wheel 16. Spring pressed blades 40 (Fig. 5, not shown) are provided to clean the rollers 32. The timing mechanism for swivelling the coiler head between the two stations is similar to that in Specification 789,592 but is combined with a ratchet and pawl device for each can table so that each can table is only rotated when the coiler head is above it. Each pawl is spring urged against its ratchet but is lifted therefrom when a taut wire, connected to it, is further tensioned. This tensioning, which occurs when the coiler head is above the other can table, is caused by the arm which swivels the coiler head.

Abstract: 210,431. Loewe, B. Jan. 24, 1923, [Convention date]. Silk (cocoons), cleaning; processes.-In reeling off silk cocoons, the silk worm papae may be first killed by immersion in a bath containing neutral or alkaline salts, mineral or organic acids, or oils, which dissolve in or can be emulsified with alcohol or ether, then treiated, either directly or after drying, in a solution of alkali or alkaline earth, either caustic or combined with weak acids at ordinary temperature or lower, 'and then reeled off while in a moist or wet state in air or in cold water. The action of the bath may be accelerated or retarded by adding soap or oil thereto. The cocoons after treatment in the alkaline bath may be dyed in a bath to which oils are added, and then reeled off. The reeled off threads, Grebes or twisted silk, is then scoured in hot water. The elasticity, flexibility and toughness may be increased by the addition of glycerine, glucose, or other substance. The process may be carried out in a vacuum or under pressure.
