Title: Improvements relating to slicing machines
IPC: B26D1/143
Filed: 1936-11-06
Abstract: 484,583. Slicing-machines. LAMBERT, F. T. Nov. 6, 1936, No. 30277. [Class 28 (ii)] In a slicing-machine having a rotary knife and a reciprocating carriage, the knife is so mounted that it can be swung about an axis lying at right-angles to its axis of rotation, the angular relation of the cutting plane to the feed movement being thus varied. As shown, the knife 13 is mounted on a shaft 14 journalled in a gear box 15 pivotallymounted on a stationary bracket 21, the box being mounted on an arm 20 secured to a pivot shaft 22 journalled in the bracket 21. The shaft 22 is in line with the shaft of a motor 19 connected by sprocket gearing 18 with a shaft 17 geared to the knife shaft 14 by bevels 161, 162. The gear box and knife may therefore be swung from the normal vertical position, in either direction, to an inclined position. The swinging may be effected by a worm 24 meshing with a worm wheel 23 on the shaft 22, the worm being journalled in a bracket 25 on the machine frame 10. The worm may be turned manually by the handle 26, or automatically, in the operation of the machine, by a pawl 29 associated with a ratchet wheel 27. The pawl is reversible and is mounted on a lever 28 connected to a rod 30 which is displaceable against the action of a return spring by an adjustable striker 32 on the reciprocating carriage 11. The spring is strong enough to effect the feed. The machine may thus be operated with a constantly varying knife inclination according to the variation in the thickness of the material being cut. The clamp means comprise a serrated bar 40 carried by arcuate arms 41 pivoted at 42 to the feed table. Members 43, pivoted at 44 to the feed table, each carry a detent 45 which is engageable with teeth on the respective arm 41. Each detent is slidable in a slot 47 and is urged by a spring 48 into engagement with the teeth, to maintain the bar in clamping engagement with the meat.

Title: Improvements in or relating to a method of and apparatus for making mouthpiece cigarettes of oval cross-section
IPC: A24C5/52
Filed: 1950-12-12
Abstract: 709,202. Cigarettes and cigarette-making machines. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Dec. 12, 1951 [Dec. 12, 1950], No. 30305/50. Class 130 To produce mouthpiece cigarettes of oval cross-section the apparatus described in Specification 709,197 is modified by the provision of a suitably shaped roller 30 free to rotate and co-acting with the stub feeding wheel 9 to deform round stubs fed from the supply drum 15 to oval shape. The roller 30 may alternatively be positioned to co-act with the composite rod of stubs and tobacco filler lengths immediately before it passes under the tongue 21 of the wrapping garniture, or may be omitted where the stubs are soft enough to be deformed by the garniture, which is suitably shaped for forming oval cigarettes. A stub-positioning and tobacco-advancing device 22 as described in Specification 709,203 is provided. The spaces between filler lengths into which stubs are to be inserted are cleaned by timed intermittent air blasts from a blower device 27, and a suction nozzle 28 is provided to keep the exterior of the cigarette paper web 20 clean. Acording to the Provisional Specification the roller 30 may be used in the apparatus described in Specification 703,982 to co-act with the composite rod immediately after it has left the stub feeding wheel and the scraper associated therewith.

In a gas e.g. natural methane liquefaction process wherein highly compressed methane issuing from a compressor 2 at say 3,000 p.s.i. is liquefied in exchangers 6, 7 the pressurized liquid methane is passed through a hydraulic motor e.g. a Pelton wheel 8 without any substantial revaporization and is then expanded at a valve 10 into a flash vessel 11 at about 16 p.s.i. from which liquid methane is discharged by a pump 13 into a storage tank 12 and flash-off vapour passes through a line 14 and the exchanger 6. The exchanger 7 is cooled by a closed nitrogen cycle comprising a compressor 19, an ammonia-cooled exchanger 20, an expansion engine 21 and a line 18. The expander 21 and motor 8 assist in driving the compressors 19, 20. Specifications 852,844 and 883,656 are referred to.

Title: Improvements in or relating to machines for winding balls of thread or the like
IPC: B29D99/00
Filed: 1919-12-04
Abstract: 159,630. Gray, C. H., and Hubbard, J. Dec. 4, 1919. Balling or winding thead; stop motions.-In a machine for winding balls of thread on a core, for example for winding elastic thread on a core for making golf-balls, comprising a rotatable roller against which the core is yieldingly held so as to permit it to rotate about any and every axis passing through its centre, means to turn the core about one axis in space and means to turn it to and fro about a second axis, for example by reciprocating the roller, the means for turning the core to and fro is such as to vary the amplitude and period of the movement during the winding of the core. In the machine shown in Figs. 2 and 3, the core 41 is yieldingly pressed by means of a concave roller 10 or by three caster-like balls or rollers against rollers 1, 2, mounted on driven shafts, and the roller 1 is reciprocated along its shaft against the action of a spring 13 by means of two adjustable oscillating- levers 20, 26. The roller is connected by a flexible wire to a block 16 which is reciprocated along the lever 20 by the lever 26. The roller 10 is carried by a spring- loaded plunger 8 so shaped as to be prevented from turning. A rod 47 normally engages a spring-controlled belt-shifting bar 52 to maintain the driving-belt on the fast pulley, but is operated to release it and stop the machine by the plunger 8 when the ball is fully wound, and by a spring- controlled lever 54 upon breakage of the thread. In the Provisional Specification is it stated that the plunger-carried roller may be traversed, and instead of being concave may be parallel with spring-pressed flanges.

IPC: C10G7/02
Filed: 1931-11-09
Abstract: <PICT:0386075/III/1> In the stabilization and debutanization of naphtha by fractional distillation under pressure to separate the naphtha into light and heavy fractions followed by compression of the light fractions and rectification of the condensate obtained, the heavy fraction withdrawn from the fractionating zone is stripped to remove light ends which are returned to the fractionating zone. Cracked naphtha vapours are passed into a fractionating tower 1 maintained under a pressure of 120 lbs. per square inch and cooled by coils 3, 4, through which the cracking stock may be passed, the temperature of the tower being kept about 190 DEG  F. by a reboiler coil 5 and by steam admitted through a pipe 6.  The light fractions pass off through line 13 and are cooled under pressure in a cooler 14, the condensate being collected in a receiver 15, separated from water in a separator 17 and then returned through the line 19 as reflux to the tower 1.  The heavy fraction collecting in the tower 1 is run off through a line 8 to a stripper 9 where it is stripped with steam, the vapours being returned to the tower through a pipe 10 or in part directed through the line 15 to mix with the vapours in the cooler 14, while the stripped residues are run off through a line 12 through a reboiler coil 52 in a tower 35 to a cooler 40 and thence to storage.  The vapours passing from the vessel 15 are compressed to 250 lbs. per square inch by a pump 21 and then passed into a cooler 22, condensate being separated in a receiver 23 while the residual vapours are compressed further to 500 lbs. by a pump 25 and passed through a cooler 26 to a separator 27, from which residual gases are run off through an absorber plant 29 to be burnt.  The condensate collecting in the separators 23, 27 is rectified with reduction of pressure in a bubble column 35, heat being supplied by the coils 52 and by an auxiliary reboiler 41, the vapours passing off at the top of the column being condensed in a cooler 45, freed from gases in a separator 46 and returned to the column as reflux through a line 47. Stabilized light naphtha is withdrawn through a line 50 and cooler 51 and has an end point of about 300 DEG  F., is free from propane, and may be mixed with the debutanized fraction withdrawn through the cooler 40.
