Abstract: 1469459 Winding adhesive tapes NISHIMURA SEISAKUSHO CO Ltd 10 June 1974 [8 June 1973] 25668/74 Heading B8R An apparatus for winding adhesive tapes F2, Fig. 1, produced by slitting an adhesive web F1 by rotary cutters 12 and provided at their leading ends with paper webs to facilitate unwinding of the tapes, comprises an intermittently rotatable arm 61 applying a strip of paper transversely of the web F, supplied from a roll and, in response to a signal representative of the winding of a predetermined length of tapes or cores 14. The signal is generated by a device 81 operable manually or automatically to rotate an arm 61 carrying the paper tab strip through one revolution in association with a single position clutch 70 and in synchronism with other driven parts of the apparatus. The arm 61 triggers a microswitch 130, Fig. 5, which starts a timer 82. The timer 82 and the signal generating device 81 are responsible for cutting the adhesive tapes wound on the cores 14 at the trailing edges of the tabs as they pass over a cutting cylinder 20. The timer 82 actuates a pneumatic cylinder 40 whose free piston rod end supports a cam lobe (32, Fig. 3) which is lowered radially inwardly towards shaft 21 about which is arranged a stationary cam race 30. The cutting drum 20 which carries the radially movable cutting blade 23 also supports a bellcrank lever (27) one end of which has a cam follower roller (26) which rides over the cam lobe (32) to project the knife blade radially outwardly into a cutting position and then retract it into its inoperative position, whereupon the cam lobe is retracted again. Tape winding is carried out at two locations C, D. At the first location C the cores 14 which are released by a bail 59 come into contact with the cutting drum 20 for applying the cut end of the tapes to the cores and winding a small number of turns on the cores, which are carried by arms 17 articulated to an indexable support. The support is then indexed to the second winding D position at which the cores 14 are contacted by a winding cylinder 16 which completes winding the rolls 15.

Title: Record sheet having a pressure-rupturable coating
IPC: B41M5/124
Filed: 1961-07-20
Abstract: 931,885. Paper with pressure-rupturable coating. NATIONAL CASH REGISTER CO. July 20, 1961 [Aug. 26, 1960 ; Oct.,3, 1960], No. 26409/61. Class 96. A record sheet comprises a base material having coated on one side thereof a pressurerupturable matrix containing a dispersion of liquid droplets including a substance capable of producing a visible or a latent image, the liquid being releasable from the matrix by the local application of pressure, and the base material having a porosity such that, on release of the liquid, the substance passes through it to produce an image on the uncoated surface. As shown, a sheet 10 of porous material, e.g. paper or fabric, is provided with a pressurerupturable matrix coating 11 containing droplets of coloured dye material and a second coating 13 of flow-metering polymeric material. 12 is a copy-receiving sheet. When pressure is applied locally, e.g. by a stylus 14, the matrix is ruptured at 15 and a portion of the dye thus released penetrates through the sheet 10 to form a coloured mark 17. Another portion of the dye penetrates through the flow-metering layer 13 to form another coloured mark 18 on the copy-receiving sheet 12. In a second embodiment, not shown, the marking material in the matrix is colourless, and the upper surfaces of the sheets 10 and 12 are both provided with coatings which will react with the marking material when it is released to form the coloured marks 17 and 18. In a third embodiment, not shown, the liquid inclusions in the matrix contain a dye and a pigment of different colours. When the droplets are ruptured, the dye penetrates the sheet 10, but the pigment is filtered out thereby, so that the mark 17 shows the colour of the dye only ; the metering layer 13, however, is permeable to the pigment as well as the dye, so that the mark 18 shows the combined colour. In a fourth embodiment, not shown, the marking material is a phototropic dye material. When the droplets are ruptured, a colourless latent image 17 is formed, and may be made visible by irradiation. Any of these embodiments may be modified by omitting the layer 13, or by making it impermeable if no copy sheet 12 is to be used. An oversheet may be placed on top of the sheet 10 so that a further copy is formed on its under side. The Specification includes lists of suitable dyes, pigments, matrix materials and flow-metering coatings for all embodiments, and describes the preparation of the coating composition and its application to form the layer 11. The reactive material used in the second embodiment may be attapulgite clay. Specification 845,939 is referred to.

Abstract: 412,543. Solidifying gases. HESSLING, W., 33, Quai Wilson, Geneva, Switzerland. Sept. 22, 1932, No. 26422. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 23, 1932]. [Class 8 (ii).] Liquid carbon dioxide, or other commercially liquefiable gas such as butane, methyl chloride, acetylene, oxygen or ammonia, is expanded through a nozzle 3 to a pressure below triple point pressure, and the gas withdrawn, leaving a body of the solid. Gas is then passed into the container through or into the body of solid at a pressure above triple point pressure, causing the formation of liquid which impregnates the solid, and the pressure is then reduced causing resolidification. The latter process may be repeated forming layers of compacted solid. The snow may be deposited on a grating 7, gas being supplied and withdrawn either above or below the body of solid ; alternatively the lower end of the container may be perforated, gas supply and withdrawal conduits connecting with the perforations.

Title: Improvements relating to a rotary tubular furnace
IPC: F27B7/40
Filed: 1970-06-02
Abstract: 1,262,220. Planetary coolers for rotary furnaces. POLYSIUS A.G. 2 June, 1970 [22 Aug., 1969], No. 26458/70. Heading F4B. A rotary furnace 1 is provided with planetary cooling tubes 2, 3, 4 and (5, Fig. 2, not shown), each formed of a number of interconnected conical sections e.g. 3a, 3b, 3c, these sections lying parallel to but offset from one another. Material flowing through the tubes to stationary annular outlet 13 is thereby impeded by the varying size steps formed between adjacent sections e.g. 2a-2b, or 4b-4c, due to such offsetting as the furnace and tubes rotate. Unimpeded flow occurs in only one position of the cooling tubes e.g. between sections 3a-3b, and 3b-3c. Material retention times in the cooling tubes are thereby increased. The degree of offsetting at least equals the difference between the major and minor radii of the cone sections, Fig. 1, and may equal the minor cone diameter (Fig. 4, not shown) or the sum of the minor and major cone section radii, in which case conical transition pieces containing feed shoots may interconnect the cone sections (Fig. 6, not shown). The conical inclination of the sections is preferably two to four times as great as the inclination of the rotary furnace to the horizontal. Preferably the axes of all the sections lie on the surface of an imaginary cylinder concentric with the furnace.
