Title: Roll fed labelling machine
Inventor: HOFFMANN WOLFGANG W
IPC: B65C9/30
Filed: 1990-05-04
Abstract: ABSTRACT OF THE DISCLOSURE   The roll fed label applying machine of this invention features two vacuum drums. The first, a cutter drum, receives the leading edge of a web of label material and a cutting knife extending from the surface of the drum severs the web into individual labels. Since the position of the trailing edge of the label is positively determined, i.e. disposed against or immediately adjacent the front of the cutting knife, the second drum, a label applicator drum, which rotates on the same speed, is easily timed with respect to the cutter drum, and the label is transferred to it, without slippage. The applicator drum carries the label past a glue applying station or a solvent applying station or both, and then moves to a transfer station where the leading edge of the label is pressed against a rotating container. A pressure pad on the applicator drum may be extended to press the label against a rotating container, around which the label is wrapped.

Title: Helical conveyor freezer
Inventor: LANG GARY D
IPC: F25D13/06
Filed: 1990-07-24
Abstract: HELICAL CONVEYOR FREEZER                    ABSTRACT OF DISCLOSURE         A food freezer having a thermally insulated enclosure wherein an endless conveyor having a lower loading section, a main helical section and an uppermost unloading section is primarily driven by engagement between its inner edge and the sidewall of a rotatable center cage, which includes a plurality of uniformly spaced apart vertical bars.  The lower end of the center cage can be blocked, and a centrifugal blower is axially located at the upper end of the cage to suck gas from the interior of the cage and discharge it horizontally outward along the undersurface of the top wall so that it flows outward, then downward and, finally, radially inward in an overall generally toroidal pattern through the tiers of the helical belt section where it withdraws heat from and freezes the food products being carried therealong.  Various arrangements, e.g., adjustable restrictors, are illustrated for creating vertical gradients in the radial inflow of gas through the helical section so that the cold gas flows inward at a greater rate in lower regions of the helical section than in the upper region. Cryogen injection devices for spraying a cryogen, such as liquid CO2 or liquid N2, radially inward to impinge upon the food products on the belt, may be located at selected positions about the perimeter and at various vertical levels.  Radial inflow of gas adds to the effectiveness of the impinging spray against the food products; however, the overall freezer construction is also advantageously employed with mechanical cooling of the gaseous atmosphere via one or more heat exchange coils.

Title: Process for the preparation of 2,2-dialkoxy cyclic orthoesters derived from lactones
Inventor: ALSTER KAROL
IPC: C07D307/20
Filed: 1990-12-21
Abstract: Abstract of the Disclosure This invention is directed to a process for the synthesis of 2,2-dialkoxy cyclic ortho esters derived from lactones which comprises reacting trialkyl orthoformate with boron trifluoride to give dialkoxymethylium tetrafluoroborate; reacting dialkoxymethylium tetrafluoroborate with a lactone to give the corresponding 0-alkyllactonium tetrafluoroborate; and reacting the O-alkyllactonium tetrafluoroborate with an alkoxide, or alternatively with an alkanol in the presence of a base; wherein the first two steps of the process of the invention are conducted in the absence of solvents, other than the reactants themselves.  The third step may also optionally be run without solvents.            The invention is also directed to the preparation of the O-alkyllactonium tetrafluoroborate in one reaction vessel; that is, the boron trifluoride is added to the trialkyl orthoformate and the lactone in a single reaction vessel.  As the intermediate dialkoxymethylium tetrafluoroborate is formed, it reacts in situ with the lactone in the reaction mixture, thus avoiding the additional steps of separating the dialkoxymethylium tetrafluoroborate and then reacting it with the lactone in a separate step and vessel.
