Title: Automatic cleaning machine for patisserie oven trays - with conveyor belt to scraping, brushing and oiling positions
IPC: A21B3/16
Filed: 1975-10-22
Abstract: Cleaning machine for patisserie oven trays comprises a framework supporting two conveyor belts which run on two rollers; the belts are connected at intervals by crosspieces each carrying a bar projecting above the surface of the belt. The tray to be cleaned is placed on the slope; it slides down to make contact with the belt and is brough under the pliable cleaning tongues. When a bar arrives at the rear of the tray the latter is drawn along by the belt. The knives are lowered and scrape the tray when the latter bears on the two pulley contactors. The tray then comes under the nylon brush and passes on to the oiling systemf when it reaches the two contactors, the roller is lowered by the jack and a thin film of oil, from the tank is applied to the surface of the tray. this then arrives at the end of the belt and falls into the storage bin and is ready for re-use. The machine operates automatically and effects a considerable saving in manual labour to remove the debris, more or less roasted and calcined, from broken pieces of patisserie.

Title: Automatic measurement circuit for MOS structures - determines voltage threshold as function of substrate polarisation using two operational amplifiers
Inventor: COMTE MARIE-HELENE
IPC: G01R31/26
Filed: 1975-11-28
Abstract: The automatic measurement circuit determines the voltage threshold of an MOS structure as a function of the substrate polarisation. The MOS structure is kept in a state of saturation so that the drain current is constant. The voltage difference between the grid and source electrodes is then measured using an operational amplifier (7), this representing the threshold voltage of the MOS structure. Saturation is maintained by an operational amplifier (2) whose non-inverting input is connected to the drain electrode (D) of the MOS structure and also to a constant current generator (3), while its inverting input is connected to the source electrode (5) via a resistance (5) and to another constant current generator (4). The amplifier's output is connected to the grid electrode (6). The substrate electrode is earthed.

Title: Vine cultivator and sensor - has cultivator tine fixed to support arm, lifted by hydraulic jack
IPC: A01B13/06
Filed: 1976-03-08
Abstract: The device comprises a support (2), fixed by a bracket (3) to a cultivator (1) frame. There is support arm (14) for for the cultivator foot (15), and hinge bolts (9, 10) at either end of a rod with a piston and cylinder (11). This double-acting hydraulic cylinder (11) is supplied by the tractor and controlled by an electrically operated valve (13). The latter is itself controlled by a sensor rod (20). As the assembly moves forward, the sensor encounters a vine stock and is moved sufficiently to operate the valve, which in its turn causes the hydraulic cylinder to operate in such a way that the arm with its foot is prevented from striking the vine stock, being routed around it instead.
