IPC: B65B51/16
Filed: 1964-05-29
Abstract: 1,046,660. Packaging-machines; article grippers. K. OTT, [trading as HABRA-WERK WILHELM F. OTT]. May 29, 1964 [June 26, 1963], No. 22267/64. Headings B8C and B8H. A machine complete filled parallelepiped bags of paper or the like in direct succession to the production and filling of the bags, by receiving the bags in radial compartments formed in one or more intermittently rotatable drums, on which it folds over the end seams and folds in and seals triangular side tabs protruding from the bag corners and passes the completed bags in an upright position to removal or packing devices. Fig. 1 is a cross-section of one embodiment which receives bags with heat-sealed upper and lower seams and laterally projecting flaps, Fig. 14 (not shown), and discharges them with folded-over lower flaps and upwardlyprojecting upper flaps, Fig. 15 (not shown). The drum 11 has compartments 12 1 -12 6  open at both end faces of the drum. The bag 1 from a filling machine is gravity fed into the compartment 12 1  with the closure end 6 facing radially inwards. Members 13 on both sides of the drum assist in pressing down the seam 7 and, during rotation to position 12 2 , triangular side tabs 8 are disposed on both end faces of the drum by fixed folders (not shown) and their layers sealed together by heated rams 21. During this same rotation the upper bag seam 4 is pressed flat against the bag bottom 3 by a folder 17, and folders (not shown) place side tabs 5 in the vertical plane by means 20 operating from both sides of the drum. As the bag rotates to position 12 3 , ploughs 22 fold the side tabs 5 against the bag bottom 3 and in this position 12 3 , sealing jaw 30 above and tongue 29 beneath the seam 4 combine to seal the latter to the side tabs 5. At the inner end of compartment 12 3  a cutting device 36 severs the corners of the flaps 8. The completed bag 1 is then dropped from position 12 4  on to a plate 40 from which the bags are successively slid by a plunger 41 on to supporting plates 44, 45. These plates move apart for the full battery of bags to drop into dispatch container 47 which is lowered and carried away on a conveyer belt 47a. In another embodiment, a twin rotating drum assembly (Fig. 9), both sets of triangular side tabs may be sealed against the ends of the bags. Bags in passage from the entry position 1 to position 1b have the side tabs 5 folded up then inwards over a heated bar 73 by reciprocating blades 91. A ram 74 finally seals them to the bag bottom. The bags are ejected at 1w by means 76 6 to the second drum where identical operations are performed on the side tabs 8. After the finished packages have been collected on the plates 44, 45 as before, their top seals are engaged by grippers on a head 88 and lowered into a container 47. Blocks &c. may be placed in the pockets to reduce their radial dimension to accommodate different sized packages, Figs. 10, 11 (not shown).

Title: Improvements in or relating to process for reclaiming rubber
IPC: C08J11/06
Filed: 1931-08-11
Abstract: Rubber is reclaimed from goods reinforced with fibrous materials, by comminuting the material and subjecting to the action of microorganisms capable of destroying cellulose, and subsequently recovering the rubber substantially free of such materials.  The microorganism may be thermophilic or mesophilic anaerobic bacteria, or aerobic bacteria, or a cellulose destroying yeast or fungi, which are obtained from river slime, dung, septic tanks, sewerage screens, etc.  The scrap rubber is placed in a tank together with a nutrient aqueous solution containing ammonium nitrate, dipotassium hydrogen phosphate, sodium chloride and calcium carbonate and incubated under conditions appropriate to the particular micro-organism used.  Owing to the absence of acid or alkali, it is possible to use plasticizers which are sensitive to acid and alkali, for subsequent treatment of the reclaim.  The microorganisms also attack the fatty and wax-like constituents of the rubber, and by regulating the degree of fineness of the scrap it is possible to control the amount of these materials which the bacteria will remove.
