Patent FR-2224642-A1 (FR)
Title: Gas turbine power station operation system - decompresses air from receiver in motor driving auxiliary compressor
IPC: F02C6/16
Filed: 1973-04-03
Abstract: The power station incorporates a gas turbine coupled to an alternator, and an electric motor coupled to a main compressor supplying a compressed air receiver, for use during peak-load periods. Before the compressed air reaches the gas turbine combustion chamber, its pressure is released in one or more air motors driving auxiliary compressors. These supply a quantity of air added to the air flow emerging from the air motor and delivered to the combustion chamber, and thus artificially increase the receiver energy capacity. The air flowing from receiver to motor can be reheated by the turbine exhaust, bringing it to a temp. level near to that of the air from the auxiliary compressor.

Title: Support system for vine shoots - has clip support and training wires and clips
IPC: A01G17/08
Filed: 1974-03-27
Abstract: The system comprises a training wire (2) and a support wire (3) parallel to and above it, the wires running along the vine row and being attached to end stakes. Each of several clips (5) has an eye which is clipped over the support wire so the end of the clip hangs down just below the training wire. The vine shoots are twisted around the training wire in such a way that the end of the clip comes between the wire and the shoot which is thus prevented from untwisting itself and is firmly secured. The shoots can be quickly and easily released for pruning by simply removing the clips.

Title: Single piston double valve pump - has two valves connected to opposite ends of tee with branch connected to piston
IPC: F04B53/10
Filed: 1974-07-02
Abstract: A pump of very simple construction has two valves (1, 2) each with a valve member which is lifted from its seating by the flow of liquid through it, with a Tee connection (3) between them, with the branch of the Tee connected to a cylinder (6) inside which a simple piston (4) is raised and lowered by an operating lever (7). One side of this arrangement is connected to the suction pipe (12) fitted with a filter (13) and the other side is connected to a simple stop valve (15) at the discharge end. The piston carries sealing rings (5) and has also a flexible disc (8, 10) top and bottom secured by washers (9, 11). When the piston lifts, the first valve (1) opens and the second valve (2) closes so that liquid is drawn into the cylinder. The down strokes causes the second valve to open while the first valve closes so that liquid is forced towards the stop valve which also opens.

The weight of the user, when seated, locks the lever against the cable and prevents descent. An exterior handle (9) is fixed to the lever and, when this is pushed down, the chair is released and descends under the control of the user.
Patent FR-2246779-A1 (FR)
Title: Synchronised belt and pulley transmission - has perpendicular drive shaft between pair of parallel driven shafts
IPC: G01D13/06
Filed: 1974-10-03
Abstract: The transfer of a tape or ribbon wound up on a shaft, to a second parallel shaft, requires synchronised rotation. In order to keep the tape under tension, the shaft which receives the tape has to rotate fractionally faster than the shaft from which the tap eunwinds. This speed differential is achieved by having the friction belt driving the two shafts on different diameter sections. The two shaft diameters are linked by a taper so that the drive belt is free to move from the larger to the smaller diameter and vice versa. When the tape transfer is reversed, the drive belt motion is to be reversed. This causes the belt to drive the receiving shaft on the larger diameter and the dispensing shaft on the smaller diameter. In this way the correct speed differential is automatically maintained.
