Title: Method of and apparatus for producing thermoplastic articles
IPC: B29C48/10
Filed: 1967-04-12
Abstract: 1,135,863. Moulding thermoplastic articles. K. MAGERLE. 12 April, 1967 [21 April, 1966], No. 16700/67. Addition to 971,921. Heading B5A. In a process of moulding the neck of a tubular container, a predetermined quantity of plastics material is extruded as an annular bead from a slot 431 of a nozzle 427 into a cavity 425 formed by mould parts 407, 415 in a holder 401. A cylindrical core or mandrel 435 carried on a turntable is surrounded by a tube section 437 of thermoplastic material and aligned with the mould, whereupon the mould holder and extrusion nozzle are lowered. The extremity of the nozzle abuts the neck 443 of the core, and during further lowering of the holder the extruded head is sheared from the nozzle by the face 423 of the part 411 and deposited around the core neck, Fig. 3, during which time the parts 407 and 415 are forced together against springs 21. The extrudate blank 451 is keyed to the core by a dovetailed annular groove 449. After raising the mould holder, the core is carried to a heating station, Fig. 4, not shown, where a cup-shaped member 461 integral with a metallic member 459 is heated by an induction coil 457 and surrounds the blank and the upper end of the tube section. The heated core is now fed to the moulding station where the tube end is received in a mould section 491 Fig. 5, and the blank is compressed by an upper pair of opposed slides 487 to form a threaded opening 489 of the tube; some of the blank is forced downwardly and fuses with the upper end of the tube. In a modification of Figs. 1-3, the bead is extruded into a cavity of a single piece mould, the extrusion nozzle is retracted to leave the bead at the mould base, the mould is then lowered on to the core and the bead is forced by compres-  sed air downwardly on to the core.

IPC: F21H5/00
Filed: 1919-07-03
Abstract: 152,088. Ward, T. E. July 3, 1919. Mantle-carriers. - A mantleholder of the flanged ring or frame type is supported above, and at an inclination to the axis of, a vertical acetylene or atmospheric burner so that a disk or piece of smooth fabric may be readily dropped into the holder without moving it. The disk may be flat, concave, or corrugated, preferably concentrically, and is retained in position by a device such as a ring, a perforated or reticulated disk, an annulus, a part of a ring, or an arcuated part. In one form in which the chimney-gallery is supported by means of an inner upwardly or downwardly turned flange e on a collar b on a socket a carrying the acetylene burner c, the flanged holder m of L-shaped cross-section is riveted to the inclined end of a thin narrow metal strip k, the lower perforated bent end of which is riveted to the gallery. A small metal ring formed in some cases with an upwardly turned part to act as a handle rests on the incandescent fabric within the holder. In some cases, especially when the chimney is of square cross-section, the holder m is made rectangular and has a circular, square, or other shaped opening. In a modification, the support is of wire with a loop &c. to receive the holder.

Title: Improvement in the manufacture of dimethylol urea
IPC: C07C275/10
Filed: 1927-06-24
Abstract: 299,487. Pollopas, Ltd., Baly, E. C. C., and Baly, E. J. June 24, 1927. Dimethylol urea.-Dimethylol urea is made by condensing urea with formaldehyde (preferably with a small excess of formaldehyde) in cold aqueous solution having a faintly alkaline reaction. The alkali concentration should not exceed that corresponding to 0.02 N caustic soda, since if that concentration is exceeded heat is evolved to such a degree that undesirable byproducts are formed. Alkaline buffer solutions mav be used to maintain the desired concentration. In an example, a mixture of urea with formaldehyde in 10 per cent excess, to which sufficient caustic soda has been added to give an alkalinity of 0.01 N, is stirred for 24 hours at 15-20‹ C. The product melts above 134‹ C., usually at 138-140‹ C. Specification 213,567 is referred to.

Abstract: 111,847. Soc. Anon. des Etablissements L. Bleriot. Nov. 20, 1916, [Convention date]. Commutators are made by assembling the conducting segments c and insulating-plates d in a cylindrical casing a of malleable metal, with an insulating-ring b between the casing and the commutator parts and then compressing the whole radially. The compression may be effected by forcing the assembled parts through a ring f having a tapering aperture, and a holder g in which the commutator is to be mounted is arranged to receive the commutator directly from the ring f so as to prevent re-expansion of the parts. To facilitate forcing the assembled parts through the ring f, the casing a may have a bottom plate a between which and the parts c, d is placed a heavy metal plate e. After the compression has been effected, the plate a is cut away and the plate e removed. The commutator is then machined, and if required for use with external peripheral brushes suitable rings are machined out of the casing a to accommodate the brushes, leaving other rings to support the parts c, d.

Abstract: 129,639. Chalas, A; July 10, 1918, [Convention date]. Drawings to Specification. Meat juice, concentrating; film evaporators; spray evaporators.-In the preparation of meat extract, plasma expressed from muscle is concentrated in vacuo, preferably near its freezing-point, the vapour being absorbed by concentrated sulphuric acid or anhydrous zinc or calcium chloride. The juice may be treated in a bulk evaporator provided with stirrers, or on the surface of a rotary drum, the lower part of which is immersed in the juice and the dried juice removed by scrapers. The juice may, however, be introduced as fast as it evaporates, in which case it may be dropped on to the upper surface of a rotary drum and be removed by scrapers after three-quartersof a revolution. The heat necessary for evaporation may be supplied by the circulation of tepid water or air, by electricity or otherwise. A spray evaporator may be used, in which a jet oi liquid impinges on an obstacle and is warmed by electric lamps. In this case, the temperature need not be kept so low as in other forms of the process, but in no case should it rise above 35-40‹ C. The juice is preferably evaporated to dryness, in two stages or otherwise, but may be concentrated to a thick liquid and preserved by the addition of glycerine.

Title: Method of manufacturing sterilised surgical sewing materials
IPC: A61L17/00
Filed: 1931-06-12
Abstract: In the manufacture of sterilized surgical suturing materials such as catgut, silk, or silkworm gut the material is treated by incubation in a nutrient medium containing portions of animal organs so as to cause germination of any spores present and is then freed from water and treated with a sterilizing agent.  This treatment may be applied at any stage in the manufacture.  Split lengths of gut may be presterilized with iodine and this may be removed and water restored to the gut, by treatment in decreasing concentrations of alcohol. The gut is then placed in a nutrient liver broth containing also peptone, salt, and grape sugar and adjusted to an alkaline reaction by means of caustic soda, and to which dice of sterile boiled liver have been added, and is p  incubated for about four days.  The spores which have thus been caused to germinate are then destroyed and water is simultaneously extracted from the gut by treatment with Flemming's solution (a solution of chromic, acetic, and osmic acids) and with alcohol of progressively increasing strength, any usual antiseptic being added.  The steps of incubation and sterilization may be repeated a number of times until, on further incubation, no colonization takes place.  The gut may be treated when wound into the usual form (star ball or the like) so as to be ready for packing at the end of the operation.  Specification 360,796 is referred to.
