Abstract: 569,606. Concentrating suplhuric acid. INTERNATIONAL FURNACE EQUIPMENT CO., Ltd., and BAILLY, L. July 12, 1943, No. 11286. [Class 32] Apparatus for concentrating liquids, particularly sulphuric acid, comprising a pot still a connected via a duct e to a preliminary concentrating chamber d, is provided with a heater i connected to the ends of' the chamber d; part of the vapours being superheated in the heater i and then recycled to the bottom of the chamber d to effect the preliminary concentration of the acid. Sulphuric acid is introduced into the preliminary concentrating chamber d near its upper end by a pipe f, and while flowing downwards through this chamber to the still a, it is brought into intimate contact with hot vapours passing upwards and is thereby partly concentrated. The remainder of the concentration takes place in the still a from which concentrated sulphuric acid is withdrawn via a pipe s to a cooler t. The vapour leaving the top of the chamber d is in part discharged through the chimney k and in part passed through the vapour heater i which is heated by combustion gases from a furnace m and/or by combustion gases from the furnace b used to heat the pot still a.

Abstract: 671,394. Finishing yarns etc.; tensioning yarns. DAN RIVER MILLS, Inc. May 3, 1949 [May 4, 1948], No. 11764/49. Classes 120(ii) and 120(iii) [Also in Groups VIII and XIII] Reinforcing cords for rubberized tyre fabric (see Group VIII) are pre-tensioned, individually impregnated with a bonding material and longitudinally tensioned and/ or laterally compressed so as to have a substantially uniform residual stretch. As shown, a number of separate cotton cords are each drawn from a creel through a guide 22, Fig. 3, between washers 25, 26 which are weighted by a further washer 27 to initially tension the cord, and through baths 41, 42 of bonding solution and between squeeze rollers 43, 44, Fig. 1. The cords pass from squeeze rollers 44 to a snub roller 47; roller 47 may rotate at a higher speed than rollers 44, to tension the cords, and it may be provided with V-grooves which compress the cords. The cords are then drawn through a hot-air drying oven 50 (see Group XIII), passing around a roller 51, which may be V-grooved, through a compression unit 52 which may give the cords a rectangular or cylindrical shape, and around a driven roller 53, the speed of rollers 51, 53 being regulated to increase or decrease the tension of the cords through both passes through the oven. From roller 53 the cords pass to individual winders 54. The wound cords are preferably sufficiently tacky to necessitate a tension being applied in subsequent unwinding. The cords may be of cotton, or cut staple rayon, nylon or " Vinyon " (Registered Trade Mark). The bonding solution may include a phenolformaldehyde or resorcinol-formaldehyde resin and natural or synthetic rubber. Impregnation may stop short of the cord centre to leave an untreated central zone.

Title: Machine for casting metal balls
IPC: B22D15/04
Filed: 1974-03-18
Abstract: 1426843 Casting-machines SOC MINERARIA E METALLURGICA DI PERTUSOLA SpA 18 March 1974 [23 March 1973] 11858/74 Heading B3F Apparatus for casting metal balls comprises a rotatable plate 2 provided with a circular groove 7 in the bottom of which are holes 15 leading to respective underlying dies formed of two halves 16 and 17, at least one of the halves being movable radially to open the die, and means 8 for introducing molten metal into the groove 7. The means 8 includes a constant head tank 28 and a channel 31 which directs the metal into the groove 7. In front of the end of the channel there is a stationary barrier 32 which blocks the flow of metal along the groove in a direction contrary to the rotational direction of the plate 2 (the plate 2 and dies move from right to left in Fig. 2). The metal in the groove 7 passes through the holes 15 into the dies. After each die has moved through about 300 degrees from its point of filling, the die half 17 is moved radially inward against the action of a spring 18 by means of a wheel 19 bearing against a stationary cam 20. Between the upper face of the die and the lower face of the plate 2 there is a blade 21 provided with a hole (22) which, when the two die halves 16 and 17 are pressed against each other, is exactly in register with a corresponding hole 15. After the die half 17 has begun its movement away from the die half 16, the blade 21 is also moved in a radially inward direction to sever the connection between the solidified metal in the groove 7 and the cast metal ball to allow the ball to fall out of the die. A punch 25 is then moved down by a cam 26 to push away any metal which may have remained in the hole (22) of the blade 21. A scraping knife (14) removes any solidified metal in the groove 7 before that portion of the groove is again located under the pouring channel 31. The apparatus may be cooled by water contained in an annular groove outside the groove 7 and by water in a chamber defined by the upper surface of the plate 2 and a cover 10.

[Class 131.] In hair-waving apparatus comprising a casing for interiorly-heated winding spindles 20, two casing sections 2 are held together by springs 16 totally to enclose the spindle and opposed and reduced semi-cylindrical projections 12 clamp the spindle adjacent its ends. The inner edges of the bottom walls 28, Fig. 4, are maintained separated so as to present a longitudinal slot 30 through which the hair may pass freely. The sections 2 are formed with handles 4 and with semi-cylindrical portions 6 adapted to receive a pivot rod 8. The projections 12 are formed with extensions 14 in slots 18 whereof the circular springs 16 are engaged. A strip of felt may be inserted between the rod 8 and a portion 6 so as to provide a tight closure. The spindle may be heated by an electric resistance 24 having terminals 26. In use, an insulating clamp is applied near the roots of the hair which is then wound on the spindle. The casing sections are then applied with the hair passing through the slot 30. The hair is wound up further to cause the walls 28 to abut against the insulating clamp and seal the casing. In a modification, the rod 8 is formed as a heating tube containing an electric resistance having end terminals which may be connected, together with the terminals 26, to a supply by single double-plug sockets. The terminals may be replaced by four plug sockets and two-pin plugs. The rod 8 may have flanges adapted to engage externally the end walls of the sections. A sealing stuffing may be provided at the slot 30. The sections may be pressed from sheet metal and the handles and inner surfaces of the projections 12 may be ribbed or knurled.
