Title: Tape applicating and severing means
IPC: B65H35/00
Filed: 1967-10-18
Abstract: 1,209,176. Labelling machines. MINNESOTA MINING & MFG CO. 18 Oct., 1967 [19 Oct., 1966], No. 47499/67. Heading B8F. A tape 7 held (e.g. by vacuum) on a conveying surface such as the surface of a drum 12 is lifted by means 44 locally from the conveying surface so that it can be cut by means positioned on opposite faces of the tape. In the form illustrated a bridge 44 lifts the tape from the surface, and an edge at the end of the bridge co-operates with a guillotine 46 to cut the tape. The severed tape is then carried by the vacuum drum 12 to be secured to the edges or faces of sheets conveyed by rollers 31, 26. The cut edge of the tape is slightly retracted by a pin 67 operated by a solenoid 64. The tape is held on the surface of the bridge 44, which may be grooved, by suction communicated through holes in the bridge from the underlying drum. The vacuum is supplied to the drum 12 through two manifolds 31, 32, the vacuum applied at 41 over one quadrant being greater than that applied at 42 over the last quadrant of the drum. The drum 12 may be grooved. The end of the tape may be guided from the bridge 44 back to the drum by air jets. The blade of the guillotine 46 may be lubricated by a pad. The tape is fed from a reel 6 by a sand wheel 11 driven by a ratchet device 19 and braked by an adjustable device 24. The guillotine 16 may be replaced by a rotary knife co-operating with the edge of the bridge 44. The operation of the machine may be controlled by photo-cells detecting the passage of articles to receive the strip, and the control may be programmed so that either a continuous strip for a series of shorter lengths of tape are applied.

Abstract: 1375628 Filter assembly ISHIGAKI KIKO KK [trading as ISHIGAKI KIKO CO Ltd] 16 Oct 1972 [15 Oct 1971] 47642/72 Headings B1D and B1T An inward or outward flow filter assembly for gas or liquid comprises a perforate support tube 221 enclosed by an array of parallel filaments 223 which extend from end fitting 224 to end fitting 225-228, and fitting 225-228 is rotatable relative to tube 221 to wrap the filaments helically around the tube more or less, so as to vary the effective pore size presented by the filaments, to accommodate different particles to be filtered and to facilitate reverse flow cleaning. As shown several assemblies extend into a tank 229 and filtrate passes from their outlet ends 221a. Tubes 221 are fixed, but fittings 225 include pinions 237 which are rotatable by a rack 239. Before filtering, rack 239 turns fitting 225 to tighten the filaments (Fig. 2, not shown) causing the fitting to move axially against the force of spring 232. After filtering, rack 239 is moved the other way, and optionally the now straightened filaments are further relaxed by turning cam 233 to push fitting 225 leftwards. Reverse flow liquid or gas is then delivered to outlet 221a. In alternative constructions (not illustrated) both end fittings 224, 225 could be rotatable in opposite directions on tube 221. Or tube 221 could be rotatable while fitting 225 is fixed.

The refractory material in a size range 20-250 microns may be carbon, magnesium oxide or dolomite. The additive may be briquetted, using an organic binding agent such as phenol formaldehyde, to a preferred volume of 15-150 cm<SP>3</SP>. The preferred method of briquetting is by charging the Mg particles into a rotary mixer, adding the binder and then adding a proportion of the other solids, i.e. the refractory and the CaF 2  and optionally up to 5% sodium carbonate. Further quantities of binder and solids are alternately added to produce granules, which are pressed at 4-25 tons/sq in to produce briquettes. The "green" briquettes are then heated at 135-350‹C for 30-90 minutes to cure the binder and give adequate strength. The Mg may be present as Mg metal, or as an Mg alloy, for example containing up to 10% rare earths (cerium), and the MgO refractory may contain small amounts of silica, alumina, Fe 2 O 3 , TiO 2 , Mn 2 O 3 , Cr 2 O 3  and CaO. Although the additive is advantageously used in briquette form, it may be added by lance injection into the ferrous melts in granule form.
