Title: Sticks with chewing gum lumps for ice cream
Inventor: ZOLLER ROLAND
IPC: A23G3/56
Filed: 1985-08-27
Abstract: Individual sticks (2) each having a lump of chewing gum (3) for subsequent manufacture into a stick ice cream are continuously produced as follows. Chewing gum is continuously extruded (12), fed onto an endless belt conveyor (13) and then pierced from the side at intervals by a series of sticks (2) pushed in laterally into the strand of gum. For this purpose the sticks are carried on a parallel conveyor (not visible) travelling at the same speed. The strand (12) then passes through a pair of rollers (18) where it is compressed, then through a cooling chamber (19) where it is cooled to 20-30 deg. C, and is then cut into separate pieces of gum (3) each containing a stick. These are then (conventionally) coated with ice to make an ice cream.

Title: Overhead (cable transport) method having a belt which is closed into the form of a tube
IPC: B65G17/02
Filed: 1987-05-27
Abstract: Overhead (cable transport) method using a cable 2, and a belt 1 whose lateral edges include notches 5 collaborating with flexible magnets and adhesively bonded onto the edges in order to permit the closure of the belt around the cable, thus forming a flexible tube. The belt is reopened upstream of the unloading station in order to be separated from the cable and to wind around the end pulley which has a vertical axis. The transported product is discharged just upstream of the end station by sliding transversely to the belt and downwards, where the side of the belt edge is smooth on the face in contact with the product. Moreover, the vertical axis configuration of the end pulley solves the problem of reversal of the belt on the return side.

Title: Metering system automatically controlled by microcomputer for automatically dispensing foodstuffs and liquid products intended for livestock
IPC: G01F11/02
Filed: 1987-06-25
Abstract: The invention relates to a system making it possible automatically to dispense, in battery farming, amounts of liquid foodstuffs which are individualised for each animal. It consists of a cylinder 2 in which a piston 1 is actuated by a jack 8. A stop 13 of variable length limits the top position of the piston 1 and creates a variation in the metering. A screw/nut system 3-4 causes this difference in length of the stop 13 and is driven by a stepper motor 5, itself controlled by a microcomputer. The data necessary for reversing the movement of the piston 1 are emitted by two sensors 10 and 11 specifying the arrival of the jack 8 at its end of travel. Filling of the cylinder 2 is controlled by opening the ball valves 6, and the delivery of the metered quantity obtained by lowering of the mobile block 7.
