Title: Improvements in winding machines for yarn or thread
IPC: B65H59/38
Filed: 1922-05-08
Abstract: 196,489. Barbour, W. T., and Bell, W. M. May 9, 1922. Winding-machines; stop-motions.-Relates to the stop-motion of a drum winding-machine which acts, on the breakage of an end or when the roll A<1> has attained a predetermined diameter, to lift the said roll clear of the driving- drum A<2>. The roll-carriage A mounted on a pivot a, has fixed thereto a ratchet segment a<1> formed with a brake-rim a<2> on which the shoe a<3> of a weighted brake-lever a<4> acts. A plain segment B, notched at b, is mounted loosely on the pivot a and is provided with a stud b<1> on which is pivoted a weighted pawl a<5> which gears with the ratchet segment a<1>. The stud b<1> carries the brake-lever a<4>. A stud a<7> projecting from the frame a<8> carries a catch b<2> which engages the notch b and holds the segment B in its working position. A lever C' with a yarn-guide c is held up by the passing yarn against the action of a spring c<1> which encircles a rod c<2> and is compressed between a nut c<3> and a fixed lug c', the lever C<1> and the rod c<2> being attached to a member c<5> pivoted on the stud a'. When the yarn breaks, the arm C' falls and strikes a lug b<3>, thereby knocking the catch b<2> out of the notch b and releasing the segment B, whereupon the weighted brake-lever a<4> causes the roll-carriage A to turn about its pivot a and raise the roll A<1> out of contact with the drum A<2>. As the roll A<1> grows, the carriage A is raised against the brake action on the rim a<2> and the teeth of the segment a' slip past the pawl a<5>. When the roll A<1> has attained a predetermined size, a screw a<9> carried by the segment a<1> engages a lug b<4> on the catch b<2> and releases the latter, whereupon the roll A<1> is raised off the drum A<2>. The machine is re-set by raising the lever C' until a projection c<6> engages an abutment a<10> on the pawl a' and disengages the latter from the segment a<1> allowing the roll A<1> to contact with the drum A<2>. Further upward movement moves the brake lever a' back and re-engages the catch b<2> in the notch b. In a modification, the lever C<1> when lifted raises a pivoted lever the free end of which disengages the pawl a<5> and permits the mechanism to be re-set. Specification 141,858 is referred to in the Provisional Specification.

Title: Improvements in Hack Saws.
IPC: B23D49/00
Filed: 1916-09-25
Abstract: 107,490. Coats Machine Tool Co., (Rollinson, E.). Sept. 25, 1916. Reciprocating-saw machines.-Relates to hacksaw machines having two alined saws 11, 12 which approach the centre of the work from opposite sides, and consists of means for feeding and releasing the saws during successive strokes and for lubricating and cooling the saw blades. The saw frames comprise heads 10, back rods 9, and lower castings 8 which are pivoted together at 7 on a cross-head 5 adapted to be reciprocated vertically on a guide 4 by the usual crank. Hollers 31 carried by levers 30 feed the saws towards each other. Two bars 33 arranged side by side are connected one to each lever 30 and are embraced by a device 35 which alternately grips one of the bars and releases the other when it is reciprocated horizontally, and thereby causes the levers 30 to act alternately to feed the saws. The device 35 is reciprocated by a link 43, a lever 42, 45, and a connecting-rod 50 pivoted to the cross-head 5. To vary the feed of the saws the effective length of the lever arm 45 is adjustable, a variable travel of the upper end of the connecting-rod 50 being permitted by its frictional connexion 55 with the lower half. When the gripping-device 35 is in its neutral position, which is normally maintained by two springs 65, both bars 33 are free and the can be moved apart for the insertion and removal of work. The saw frames are kept in alinement by bars 26 having pin-and-slot connexions with them. The frame 1 of the machine is formed as a receptacle for the cooling-liquid, in which the open lower ends 14 of the hollow rods 9 of the saw frames work. A check-valve 15 in the open end 14 ensures a flow of the liquid through each rod 9, a passage 17 in the head 10, and through passages 24, 23 in the adjustable sawtensioning member 19, and to the saw blade 12. The flow of liquid is regulated by a valve 25.

Class 39(iii) A panel heater comprises a back plate 3, a front plate 5 detachably hooked to the plate 3 at the top at 16, a lower wallmounting 6 adapted to lock the back plate 3 to a lower flange on the front plate 5, and fastening means, e.g. a screw 9, below the bottom of the panel, for connecting the mounting 6 to the wall. There are two mountings 6, one at each side of a centrally positioned junction box 4 on the back plate 3, and each mounting 6 comprises an inverted U-shaped member the front leg 10 of which passes through a passage formed by a plate 11 welded to the back plate 3, see Fig. 2. An end part 12 of the leg 10, of reduced width, passes through a slot in a lug 13 welded to the bottom of the front plate 5. To separate the plates 3, 5 it is first necessary to remove the screw 9 and lift the mountings 6 out of the parts 11, 13. For stowage, the rear arm 7 of the mountings 6, which is of reduced width, is inserted upwardly through the slot in the lug 13 and behind the plate 11, the arm 10 then lying in front of the panel. The rear plate 3 is conventionally supported at its upper edge.

Title: Dispersing gases in liquids
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: C07C51/265
Filed: 1957-05-01
Abstract: In a process for the oxidation of alkyl substituted aromatic compounds to terephthalic acid in an inert liquid medium, gaseous oxygen is passed into the liquid between the helices of a coiled spring which is closed at one end.  The process may be used in the air oxidation of paraxylene and para-diisopropyl benzene to terephthalic acid in a liquid medium such as water or a carboxylic acid such as acetic acid and, if desired, in the presence of a heavy metal catalyst and bromine or a bromine-containing substance such as cobalt bromide. Specifications 807,091 and 833,438 are referred to.ALSO:Gas is dispersed in a liquid through a helical spring closed at one end.  The coils of the spring are normally closed but the pressure of the gas extends it sufficiently for gas to pass between the coils.  Variations in gas flow cause the spring to flex and the consequent lateral movements between the coils clears any solid building up on the spring.  To avoid corrosion the spring may be made of titanium or it may be a metal spring coated with P.V.C. or polythene.  The process may be used in the air oxidation of alkyl substituted aromatic compounds such as para-xylene and paradiisopropyl benzene to terephthalic acid in a liquid medium such as water or a carboxylic acid such as acetic acid and, if desired, in the presence of bromine or a bromine-containing substance and/or a metallic catalyst.
