Patent FR-2269786-A1 (FR)
Title: Ring core made from radial laminations - with more iron at the outer than at the inner diameter
IPC: H01F37/00
Filed: 1975-04-30
Abstract: The core construction is suited to the production of ring type reactors with an enclosed winding in the core centre. Typically the inner diameter of the core is half that of the outer. The laminations are rectangular, but with part of one long side cut away to give a resultant J-form. These laminations are threaded radially round the coil winding such that the long side of the J lies at the outer diameter of the core. The laminations are arranged with their short sides, which therefore lie at the inner diameter, alternately pointing left or right. Thus the iron content of the region near the outer diameter is twice that of the inner region, and a reasonably cylindrical magnet results. The short limb is typically slightly under half the length of the long side in order to produce a small air gap.

Title: Straddling tractor grape gathering attachment - has oscillating shaker fingers with grapes falling onto side conveyors and leaves removed by fan
IPC: A01D46/28
Filed: 1975-11-03
Abstract: The attachment fits on a portal type tractor and is used to gather grapes. The tractor staddles the row of vines and the grapes are removed simultaneously from both sides. A set of flexible fingers is provided for each side of the row, these being attached to arms which impart an oscillating movement, adjustable for amplitude. The grapes fall from the vines onto plates guiding them onto a conveyor at each side. Leaves are removed by a fan and the clean grapes pass through a screw conveyor into elevator buckets and a belt conveyor. They are then deposited in a hopper.

Title: Bodywork decorative moulding attachment stud - has hollow cylindrical shank with sealing and fixing flanges and hemispherical end
IPC: F16B5/12
Filed: 1976-01-06
Abstract: The stud (1) which is intended for fixing trim to car body-work has a flanged head (2) with ribs (3) suitable for the attachment of the trim. The shank (5) of the stud is a hollow cylinder with a hemi-spherical end (6). The upper end of the shank (5) has a collar (4) to prevent the ingress of moisture into the car body-work. The decorative trim is attached to the stud and the stud is then pushed through a hole in the body- work which is of such a diameter that the metal around the hole snaps into a groove (9) and prevents the stud being withdrawn. The insertion of the stud is aided by the external taper (V) of the shank.

Title: Float operated valve for tank with low output rate - has lower float controlling opening of valve and upper float to close it
IPC: A01K7/04
Filed: 1976-01-20

The bottom edge of the lever arm is bevelled and makes contact with a short lever (17). The end of this lever is connected by a link mechanism to a lower float (21). When the tank is empty both floats are down and the valve open. As the tank fills the submerged lower float is prevented from moving by the lever (17) being caught under the arm (6) until the top float moves up and closes the valve.
Patent FR-2341837-A1 (FR)
Title: Water pump seal wear measurement - using optical device mounted in discharge pipes to show datum mark movement
IPC: G01B11/02
Filed: 1976-02-20
Abstract: The pump which circulates water in a water cooled nuclear reactor has a rotor (6) mounted on a shaft. The shaft is fitted with seals (18, 22, 27) which permit a very small leak which flows out through the pipes (23, 28). To ensure that this leak is kept within acceptable limits, seal wear is measured at frequent intervals. To avoid dismantling the pump in order to measure the wear, an optical inspection device is fitted to the pipes (23, 28). The device shows any movement between a datum mark on the pump body and a datum mark on the shaft.

Title: Flexible drive cable sheath - has separate bearing tubes enclosed in metal spiral with plastics outer tube
Inventor: LAUNAY PIERRE
IPC: F16C1/26
Filed: 1976-11-24
Abstract: The sheath for a flexible drive cable is made from a continuous spiral (1) formed by coiling a metal strip. Short lengths of plastic tube (3) which act as bearings are inserted inside the coils with a gap (4) between successive lengths equal to one third of the length (5). The spiral (1) is then enclosed in a continuous tube (2) of flexible plastic. With this construction of sheath the cable is guided by the bearings (3) whilst adequate flexibility is ensured by the gaps (4). In addition the gaps (4) act as reservoirs for grease which is prevented from migrating by the bearings (3). The patent also describes a machine for manufacturing the sheath.
Patent FR-2376566-A1 (FR)
Title: Symmetrical digital filter - makes use of symmetry characteristics and is based on generation of Mersenne modulus transforms
Inventor: NUSSBAUMER HENRI
IPC: H03H17/06
Filed: 1976-12-30
Abstract: The numeric filter is based on the use of a discrete transform making use of symmetry properties. The filter input accepts a sequential stream of samples from the signal to be filtered, expressed numerically. This stream is fed to a circuit which divides it into blocks of data having a fixed length, which appear as delayed and non-delayed streams. Four generators provide outputs using a Mersenne modulus transform. Two of the circular function outputs are fed simultaneously to the non-delayed blocks of data and the two remaining functions to the delayed blocks. The filtered signal then undergoes addition to be delivered as a sequential filtered stream.

Title: Screw mfg. using continuous rod threading - is followed by parting and welding to head to accelerate prodn.
Inventor: AESCHMANN NICOLAS
IPC: B21K1/56
Filed: 1977-03-07
Abstract: Fast and economic manufacture of screws is achieved by the separate production of the threaded shank and the head which are then joined together by welding. The shank can be threaded either by cutting tools or by rolling while the head can be formed by blanking. The separation of the two processes permits various types of heads to be made by simple means and in smaller series. Pressing of the head (40) allows a recess (44) to be formed for the small end (43) of the screw shank (41) so that a corrugated locking washer can be interposed between the head and the shank. The head may also be pressed with deflections actins as biting serrations when the screw is threaded home.
