Title: Cheeses removal from waxing bath - using a device with suction cups suspended from a hoist
IPC: A01J27/02
Filed: 1973-10-26
Abstract: Removal device for cheeses from a waxing bath is intended for semi-hard cheeses of the Gouda type; the upper hemi-spherical surface emerging from the bath is siezed by a suction cup as the wax commences to crystallise. The wax-coated cheese is then plunged into a bath of freezing water in order to complete the crystallisation process. The circular paraffin wax bath has a discharging post. A chassis is suspended by a cable from a bracket which overhangs the post. The cheeses are suspended from the chassis by tulip-shaped suction cups from which the air is withdrawn by the aspirator via the flexible tube when the chassis is no longer in contact with the buffer which is articulated on the upright of the bracket. The chassis is at its lowest point, with the piston in the jack at the top of its stroke; in this posn. the chassis is against itsstop and the air is released from the suction cups for delivering the cheeses to the discharge post. A single operator can remove up to six cheeses in one withdrawal operation; this can be done without any appreciable marking of the wax coating.

Patent FR-2278568-A1 (FR)
Title: Variable section slotted wing - has venturi flow through wing preventing vortex breakaway
IPC: B64C3/00
Filed: 1974-03-25
Abstract: The device allows the relative airflows to flow over the upper surface (14) of the wing and over the lower surface (13) in a conventional manner, and between the upper surface leading edge (1) and the lower surface leading edge (2), escaping from between these edges at a higher speed leading to a fall in pressure at these edges. This retards the separation of the airstream on the upper surface at high angles of incidence, reducing marginal turbulence. This increased speed also produces an aerodynamic flap effect with an angle equal to the angle of incidence (10) of the wing. The skin of the wing is so constructed that the section can vary according to the angle of incidence, e.g. the lower surface (13) assumes either a convex or a concave (12) shape. The controls can be located in the airstream for maximum efficiency.
