IPC: B31B17/00
Filed: 1929-05-01
Abstract: 324,596. Jagenberg, G. M. May 1, 1929. Machines for making boxes with projecting bases. A box 2, Fig. 5, with a projecting base 7 is made in a continuous operation by pressing a cardboard blank 36, Fig. 1, through a frame 39 by means of a piston 38 to form the body 2 which is then pressed by the piston against a previouslygummed base 7 which has been moved in front of the piston and is thereby connected to the body 2. As shown the bases 7 are fed from a pile 21 over a pair of spaced gumming-discs 24 to rollers 25 which feed them down rails 26 to a guideway 27 consisting of a pair of spaced angle bars between which runs a conveyer 29 having members 30 which deliver the bases to a feeder 31. The feeder 31 moves the bases against rails 32 between which and rails 34 the bases drop one at a time on to a stop 35 from which they fall on to a stop 42 in front of the piston 38 which has meanwhile advanced with the formed box body and forces the base 7 against a spring- pressed piston 43. The piston then returns to its original position and the box is stripped therefrom by reciprocating members 44 which also press the sides of the box inwards slightly and with the withdrawal of the stop 42, the completed box falls down a guide surface 45 on to a conveyer 46. The sides of the box body after being folded up by the frame 39 and piston 38 are bound by an edge-strip 50 which is pressed on to the body, while rotating, by a small roller 41 or the sides may be bound by angle strips or the frame 39 may be arranged as a drawing or shaping channel in which case the sides are not bound.

Title: Improvements in or relating to the manufacture of coumarin
IPC: C07D311/10
Filed: 1934-05-11
Abstract: Coumarin is prepared by heating salicylic aldehyde or an acetylsalicylic aldehyde with acetic anhydride in the presence of an oxide or salt of cobalt.  Alternatively, o -dichloro-o-cresol carbonate is heated with acetic anhydride in the presence of an oxide or salt of cobalt, whereby an acetylsalicylic aldehyde is first produced (with evolution of acetyl chloride), and is then converted into coumarin by the further action of the anhydride. The reaction may be effected at atmospheric or other pressure.  In the examples: (1) o -dichlor-o-cresol carbonate and an excess of acetic anhydride are heated with a small proportion of cobalt oxide; acetyl chloride is first evolved, followed by the excess of acetic anhydride and the acetic acid formed; coumarin is recovered from the residue; (2) acetylsalicylic aldehyde and acetic anhydride are heated with a small proportion of cobalt oxide.  The Specification as open to inspection under Sect. 91 states that an oxide or a carbonate, chloride or other salt of bismuth or zinc may be used in place of an oxide or salt of cobalt.  It states also that acetic anhydride may be replaced by another anhydride, such as butyric, benzoic or phthalic anhydride. This subject-matter does not appear in the Specification as accepted.
