Abstract: Apparatus for forming flaps at the top of an open-top carton after it has been packed, with the flap formation correlated to the level of the top of the contents of the carton, having means for internally scoring the walls of the carton generally at said level, means for slitting the corners of the carton generally down to said level, and means for trimming off the tops of the side walls of the carton so that they may be folded on top of the carton without overlap. In forming the flaps, the apparatus is adapted to compress the contents of the carton. The scoring means includes a set of scoring blades which fit in a carton on top of the contents and a set of external presser members for pressing the carton walls against the blade edges. The scoring blades are replaceable with blades of different sizes and provision is made for adjustment of the presser members and trimming means to operate on cartons of different sizes.

Abstract: Apparatus for packaging items in plastic bags, wherein plastic bags are formed with seams at both sides, but open at the corners at the bag mouth, whereby each wall of the bag has a flap at its mouth end, each bag being fed forward sidewise to a loading station where the flaps are clamped and separated to open the bag and the item to be packaged is pushed into the bag, after which the bag mouth is spread for being sealed, and then sealed.

Abstract: A process for preparing aldehydes, ketones, carboxylic acids and esters by reaction of various substrates with carbon tetrahalides in the presence of a strong base. The reactions are accelerated by the presence of a polar solvent. Anions of the substrate attack the carbon tetrahalide to produce a halogenated intermediate and a dihalocarbene. The halogenated intermediate reacts with the base to form the indicated products. By the reactions of this process, primary alcohols are converted to aldehydes, carboxylic acids and esters, secondary alcohols are converted to ketones and ketones having an .alpha.-methyl group or both .alpha. and .alpha.' hydrogens are converted to carboxylic acids and esters. Non .alpha.-methyl ketones having .alpha. but no .alpha.' hydrogens are simply .alpha.-halogenated. The dihalocarbene generated in the reaction may attack the product, solvent, or another substrate to form other products.

Each opening has a tooth struck from each end thereof with the lateral planes of the teeth of certain openings being skewed relative to the longitudinal axis of their respective columns at a first skew angle and with the lateral planes of the teeth for certain other openings being skewed at a second skew angle substantially equal in magnitude but opposite in direction to the first skew angle.

Abstract: A method of making a one-piece plastic container having a body, a raised bottom and a flange integral with the bottom and the body joining the bottom edge of the body and the periphery of the raised bottom, the flange being sealed to the lower portion of the body which surrounds the flange. The container is initially molded with a bottom integral with its body at the bottom edge of the latter, and the bottom is displaced to a raised position relative to the bottom edge of the body with accompanying formation of the flange.

Abstract: A process for preparing alkenes by reaction of various sulfone substrates with carbon tetrahalide in the presence of a strong base. The reactions are accelerated by the presence of a polar compound. Sulfone carbanions attack the carbon tetrahalide to produce an .alpha.-halogenated intermediate and a dihalocarbene. .alpha.-Halosulfones having .alpha.' hydrogens are converted to alkenes in situ via the Ramberg-Backland reaction. Sulfones having .alpha. but no .alpha.' hydrogens are simply .alpha.-halogenated. The dihalocarbene generated in the reaction may attack the product, solvent, or another substrate to form other products. Alkenes produced by reaction of carbon tetrahalides with di-sec-alkyl sulfones are readily attacked by dihalocarbene to form the alkene-dihalocarbene adduct (a substituted 1,1-dihalocyclopropane).

Abstract: Packaging apparatus for packaging units in flexible sheet material with the units spaced longitudinally in a tube formed of a web of the material and with the tube sealed together between successive units. The apparatus includes a rotary sealing wheel carrying a series of sealing assemblies for sealing the tube, the sealing assemblies being uncoupled from the wheel and held at a hold position for again being released in timed relation to movement of the tube for sealing the tube between successive units. The apparatus also includes an electronic pulse counter or encoder driven at a speed proportional to the speed of the wheel to effect the release of a sealing unit in the event the passage of a unit to be packaged is not sensed by a photoelectric sensor when packaging the units in unprinted sheet material, or to control the placement of units to be packaged on a web of the material having registration marks preprinted thereon.
