A packaging machine of the kind comprising an endless series of linked dies in which a web is moulded to form joined containers and afterwards filled and closed by another web after evacuation, while still in the die, has removable die partition members enabling the machine to produce a pair of packages from each die. The die and die partition have resilient beading at their upper edges with tight seal forming means adjacent the ends of the partition. The lower web 18 may be drawn into the dies as in Speci - fication 949,747 and loaded with frankfurters &c. by means as described in Specification 1,036,929. The partition 16 (shown fitted in only one die) is located by friction and lugs 113 entering recesses in the die base, Fig. 6 (not shown). Clamps 22 grip the web edge and a cutter 26 forms an evacuation opening. The second web 32 overlies the clamps on the evacuation side and when the sealing head holder 36 (shown as hinged back for maintenance &c.) is lowered, is pushed up against a resilient member 76 on the head by a vertically reciprocating combined web raiser and evacuation nozzle 28, see also Figs. 3-5 (not shown). The head comprises an initial partial sealer 44 which leaves the webs unsealed on the evacuation side and along most of the partition, and a final sealer 46 which includes two bars 82, 102 reciprocable vertically relative to the head, the latter itself being vertically reciprocable. The bars 82, 102 complete the package closure, the latter forming, with beads 52 on the partition, parallel spaced seals enabling the twin packages to be separated. If the partitions are not used, the bar 102 may be disenabled by removal of its operating push rod 96. The web raiser may be used to introduce inert gas into the packages.

Title: Method of preparing carbonyl compounds from olefinic hydrocarbons
Filed: 1962-06-04
Abstract: Olefinic hydrocarbons, defined as including open chain olefines, cyclic olefines and compounds having an olefinic unsaturated linkage attached to the aromatic ring, are converted into one or more carbonyl compounds by contacting with an oxidizing agent comprising an aqueous suspension or solution or mercuric nitrate at a temperature in the range from 0 DEG  to 50 DEG  C. and thereafter heating the resulting reaction mixture to a temperature in the range from 50-180 DEG  C.  The invention also includes a modification wherein the olefinic hydrocarbon is contacted with the oxidizing agent in one stage at a temperature from 150-180 DEG  C.  The preferred embodiment of the invention employs aqueous nitric acid as the solvent for mercuric nitrate. The nature of the composition of the carbonyl compound obtained may be altered by adding to the oxidizing agent a metal nitrate especially ferric, cupric, silver, nickel, cobalt, bismuth, thorium or aluminium.  Specially suitable olefins are ethylene, propylene, or a butene.  The process may be made continuous by a further modification wherein the spent oxidizing agent is regenerated by treatment with nitric acid oxygen or an oxygen containing gas.  Using mercuric nitrate only, propylene is oxidized to acrolein, butene-1 is oxidized to methyl-vinyl ketone. Using mercuric nitrate together with another metal nitrate, ethylene may be oxidized to acetaldehyde, propylene to acetone, butene-1 to methyl-ethyl ketone, isobutylene to isobutyraldehyde, butene - 2 to methyl - ethyl ketone.  An integrated process for a conversion of propylene to acrolein is described with reference to a flow sheet (not shown), and the description includes a study on the effect of the molar ratio of metal to mercuric ions on the composition of the carbonyl compounds obtained, and a similar study for the ratio of silver to mercuric ions in the case of oxidizing propylene. A study of the effect of admixture of the various other metal nitrates is also included. Detailed examples of the oxidation of propylene, butene-1 and isobutylene using mercuric nitrate alone or in combination with one of the other specified metal nitrates are described.

Abstract: 1278916 Eviscerating poultry INTERNATIONAL AGRI-SYSTEMS Inc 19 April 1971 [6 Feb 1970] 21550/71 Heading A2U Poultry eviscerating apparatus comprises a conveyer 24, 26 from which carcases are suspended by brackets 32, and an endless chain conveyer 40 synchronized with the conveyer 24, 26 and carrying a plurality of carriages 50 on each of which is mounted a nested pair of downwardly concave spoon members 60, 104 for withdrawing the viscera. As shown, the apparatus is duplicated on each side of a longitudinal division 22 surmounting a trough 10 so that two rows of poultry can be dealt with simultaneously. A carcase is slit and suspended by the hocks from a bracket 32 so that the corresponding pair of spoon members enters the body cavity. Then, as the carcase is conveyed to the right a point is reached at which a cam track 130, coacting with a follower 70, terminates allowing a spring 68 to swing the lower spoon member 60 clockwise about a pivot 58 into engagement with the viscera, a roller (not shown) bearing against the outside of the carcase to steady the latter during this operation. A follower 116 then engages a cam track (not shown) to move the upper spoon member 104 anti-clockwise about a pivot 102, after which the lower spoon member is caused by a further cam track (not shown) to follow the member 104 but at a slower rate so that the separation of the spoon members increases to push the viscera away from the backbone and out of the carcase. A ratchet 82 prevents any unwanted downward movement of the lower spoon member during this operation. As the carcase reaches the end of the apparatus a fixed plough scrapes the viscera from the lower spoon member, the spacing between the spoon members is reduced by a small return movement of the upper member, and an elevated portion of the conveyer rail 24 causes the carcase to be lifted off the spoon members.
