Abstract: 1493895 Trimming moulded articles MONSANTO CO 5 May 1975 [6 May 1974] 18721/75 Heading B5A Preforms 18 at a temperature outside that suitable for trimming by cutting off flash 16 are detected and rejected as a series of the untrimmed preforms is fed to the trimming device 12. Extruded and partly blow-moulded preforms 18 are fed past an infra-red sensing thermometer 64 by a conveyer comprising a cooperating bar 50 and rotating screw 46 which hold and rotate the preforms by engagement with the neck flash 16. When a preform at more than 39 C. below or 19 C. above the glass transition temperature of the material thereof is detected, a section 68 of the bar 50 is retracted by a pneumatic ram 67 to release the preform and allow it to fall into a shoot 90 (Fig. 6, not shown). The removal of the preform may be assisted by a hammer 74 operated through a linkage 76 by the withdrawal of the section 68. A number of preform carriers 160 attached to endless chains 100 are arranged to travel under the preforms at the end of the conveyer and as they pass around a wheel 22 which rolls the preforms against a curved edge 13 of the cutting device. The flash is severed and conveyed by a wheel 36 to a shoot 42 while the trimmed preforms fall into the carriers 160 and proceed in direction 166 for temperature conditioning and final blow-moulding.

Filed: 1954-06-29
Abstract: 756,895. Refrigerating. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 29, 1954 [July 2, 1953], No. 19027/54. Class 29. [Also in Group XXVIII] Liquid condensate obtained with the aid of a refrigerating system of the reversed hot gas engine type is raised by a bubble pump. In Fig. 1, the liquid medium flowing from a channe 1 2 into a heat exchanger 4 is vaporized therein and returns to the cold end of the system 1 via a channel 3 for recondensation whence it flows again up channel 2. A metal element 7 is suitably positioned for it to have a temperature sufficient to produce vapour plugs to raise the liquid up the channel 2. Additional vapour plugs are formed where channels 2 and 3 are in heat exchange. An insulating jacket 6 is provided. In a fractionating system for gaseous mixtures, Fig. 2, the gas mixture is compressed by compressor 13 to flow via a duct 19 into a heat exchanger 20 resulting in some vaporization of liquid in the evaporator 11. Duct 21 leads the precooled gas mixture into a rectifying column 10, filled with Raschig rings wherein the low boiling point gases pass via a duct 22 to the cold end of the refrigerating system 14 for condensation, part of the condensate being refluxed by a duct 23 using the bubble pump effect because of thermal contact with a metal element 25, to raise it to the top of the column 10 and the high boiling point condensate collects in the evaporator 11. Ducts 29, 28, in contact with the metal element 25 provide a bubble pump for the transfer of this condensate from the evaporator 11 to a duct 30 for removal. The other part of the low boiling point condensate is withdrawn for use through pipe 24. In Fig. 4, again a fractionating system, air is compressed by compressor 57 into an evaporator heat exchanger having staggered gas apertures 46 in elements 45. Herein water and carbon dioxide separate out as solids and the mixed gases spirally flow via a duct 49 into a rectifying column 40 containing Raschig rings wherein they flow downward to meet vapour from the boiler 41, open to the air via tube 43, heated by the heat exchanger. The lower boiling point nitrogen passes via a duct 51 to the cold end of the refrigerating system 52 for condensation, part being refluxed using a duct 53 in contact with duct 49 to produce a bubble pump effect to carry it to the top of the column. The other part is withdrawn for use through a pipe 54. Specifications 695,857, 756,892 and 756,893 [both in Group XXVIII], are referred to.

Patent GB-357265-A (GB)
Title: Improvements in and relating to oil treatment
IPC: C10G9/36
Filed: 1930-06-24
Abstract: <PICT:0357265/III/1> In a cracking process of the kind in which the oils are converted in the vapour phase by direct contact with a heated neutral carrier gas the temperatures and volumes of the components are regulated so as to produce a mixture in which the percentage of sulphur present is below that at which corrosion of the apparatus takes place, i.e. under 1 per cent.  Oil vaporized in a heater 10 is passed through a pipe 11 to a reaction chamber 13 where it is cracked by contact with hot inert carrier gases supplied from a stove 15.  The temperature of the vapours is regulated by by-passing a part of the vapours through a super-heater 12, while the temperature of the carrier gas is also regulated by diverting a regulated portion of the cold gas through a by-pass 50 and mixing it with the heated gas issuing through a valve 54.  The cracked vapours and gas are led through a pipe 20 to a scrubber 21 where they are scrubbed with heavy oil pumped from a tank 41, and then enter a rectifying column 23 where heavier fractions are condensed by contact with the crude oil flowing from a pipe 24, the condensate and crude oil being passed through a pipe 35, 46, and a heat exchanger 37 to the still 10, while the condensate from the scrubber 21 is returned through heat exchangers 36, 37 to the tank 41.  The vapours and gas leaving the column 23 are passed through a condenser 26 and separator 27 and the gases are recycled by a blower 29 through an absorber 30 and the heat exchanger 36 back to the stove 15, part of the gases being stored in a holder 45 if desired.  Specification 336,380, [Class 32, Distilling &c.], is referred to.
Patent GB-573279-A (GB)
Title: Textile finishing apparatus
IPC: D06C7/00
Filed: 1943-11-18
Abstract: <PICT:0573279/IV/1> <PICT:0573279/IV/2> Apparatus for finishing textiles by treatment with steam or other vapours or gases comprises a closed chamber into which the textile in continuous form is fed, e.g. from an impregnating apparatus, means for forming the textile into accordion folds and for depositing the folds in a substantially vertical position on a horizontal conveyer and means for withdrawing the treated cloth continuously from the conveyer and chamber.  The inlet end of the chamber is shown in Fig. 2, while Fig. 5 shows the exit end.  The textile 15 falls from friction feeding rolls 16, 17, outside the chamber 10, and roll 18, inside, to a folding mechanism or guideway 19, the sides of which are made of sheet, strip or rope material and which are adjustable relatively to one another.  Jets from a horizontal perforated pipe 24 assist in stripping the material from the roll 18.  From the lower end of the guideway 19 the folded material passes to a curved lower end 20 of the guideway in alignment with the upper portion, from which it passes with the folds in a vertical position to the upper run of a continuously moving conveyer 40 formed of a number of cords.  The diameter of the pulleys of the conveyer cords at the outside is greater than on the inside to give it a dished formation and prevent lateral movement of the folds.  The conveyer speed is adjusted to the rate of feed of the material to preserve the vertical arrangement of the folds in their passage through the chamber 10.  A pick-up roll 21 has a series of discs which project between the cords of the conveyer and extend above them to transfer the material to a curved slide 22 where the material assumes more or less horizontal folds.  The cloth in unfolded condition is withdrawn from the chamber over rolls 50-53, and passed to the next process, for example a washing operation. Glands close the cloth entrance 23 to and exit from the chamber. Specifications 552,567 and 552,711 are referred to.
