Abstract: An apparatus and method for cutting frozen confection including a frame defining a product void for receiving a product at least partly coated, a set of side knives, at least two knives mounted on the frame opposite of the product void, wherein the knives are rotatable arranged on the frame such that they can be rotated into a product coating cutting position for cutting the coating on the side of the product and out of such a position to a non-engaging position to allow the product to be moved passed the knives, and an end knife for cutting the coating on the end of the frozen confection.

Abstract: A new and unique construction for a corn cob cutter knife is presented. A method is described for the manufacture of a unique cutting blade insert which is tapered and which has an inner ski angle compatible with the many applications involved in removing corn kernels from a corn cob in a mechanized operation. The unique removable cutting blade insert is designed so that the various angles of declination and attack optimize the sharpness and long lasting nature of the knife. A method is also presented to determine the off-set grinding radius for the ski angle of the knife.

Abstract: A corn cutter unit in which an ear of corn is propelled by a plurality of feed rollers into a plurality of knives carried by a rotating head, with the knives being adjustable to define an opening through which the cob may pass, and a cob puller having upper and lower chains, each of which is formed of links and driven by sprockets over a guide, which guide has a height substantially equal to the length of the individual chain links to extend through said head and grip the corn cob.

Abstract: A method for producing an aromatic carbonyl compound represented by the formula (B)-1 or (B)-2: ##STR1## comprising decomposing a hydroperoxide represented by the formula (A)-1 or (A)-2: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are defined in the specification, in an inert gas atmosphere in the presence of an aqueous layer containing an iron salt, a copper salt and an acid is disclosed. Novel m-(2-hydroxy-2-propyl)acetophenone and m-isopropenylacetophenone which are useful as an intermediate for the preparation of medicines are also disclosed. A method for producing m-isopropenylacetophenone comprising dehydrating m-(2-hydroxy-2-propyl)acetophenone in the presence of an acid catalyst is further disclosed.
