Patent FR-2503030-A1 (FR)
Title: Electronic position control for electric or hydraulic press - includes real and optimum speed sensors feeding comparator which provides control signals by which continuous adjustment is made
Inventor: BOULANGE JOEL
IPC: B30B15/20
Filed: 1981-04-01
Abstract: The system controls the linear or rotary position of part of a machine using a comparison between the real speed of the part and the required speed. As a result of this comparison repeated corrections are made to the movement of the part. In order to control the movement of the part the system includes a displacement controlling unit connected to a control system and a distribution unit. An electronic circuit includes speed detectors one of which corresponds to the actual speed while one corresponds to the desired speed determined by a potentiometer. The data provided by these detectors are analysed and compared, then sent via a power amplifier to the controlling unit. This sends instructions to the appropriate part via the distributor. The controlling unit may be hydraulic, with a filter, pump, pressure regulator, and servo-valve.
Patent FR-2482944-A1 (FR)
Inventor: WOLF IRVING W
IPC: C21B13/00
Filed: 1981-05-22
Abstract: The invention relates to a process for reducing needle-shaped iron oxide for producing needle-shaped highly orientable metal particles which are suitable for magnetic recording, which is characterized in that the oxide particles are treated with an aqueous solution of sodium tripolyphosphate, the oxide coated in this manner is dried with formation of a matrix, and the oxide is reduced by contacting this matrix with hydrogen at an elevated temperature in the presence of a dehydrating agent.
Patent FR-2508826-A1 (FR)
Title: Formation sheet metal blade helicopter e.g. - involves stretching blank whilst applying to mandrel with final reduced edge radii obtained by folding
IPC: B21D53/78
Filed: 1981-07-06
Abstract: The process may be used to form blades for wind-generators or helicopters from sheet metal. It involves subjecting a blank (17) to a transverse drawing operation whilst applying it to a mandrel (22) forming a central curved leading edge. The radius (r') of the mandrel is greater than that finally required. The angle of the mandrel opening may also exceed that of the finished work in respect of both the leading and trailing edges, the mandrel also having significant extra length (L'). The trailing edge may have a face (26) normal to the longitudinal axis (P').
Patent FR-2510289-A1 (FR)
Title: Rotating head assembly for video tape recorder - uses layers of strong and weak magnetic effect to modify reluctance and direct field through tape
Inventor: LEHUREAU JEAN-CLAUDE
IPC: G11B5/53
Filed: 1981-07-24
Abstract: A sub layer (3) of weak magnetic effect is located under a layer (2) with a strong magnetic effect. This reduces the reluctance between the surface of the latter layer and the magnetic tape (4) and the rear magnetic pole (5). The perpend-icular head has its main pole (1) consisting of a thin magnetic film on a non magnetic support adjacent to the tape. This is perpendicular to the tape on which it records as it rotates. The flux generated by a coil (6) into which the signal current is injected is concentrated by the main pole and orientated by the strong magnetic layer. The weak magnetic layer diffuses it over a large area. The reluctance in the space separating the weak magnetic layer of the rear pole is weakened before the reluctance separating the main pole from the same layer so that the field travels through the tape to record the signal.

Title: Wrench for tightening or releasing railway track bolts - comprises reversible motor driven reduction gear with torque limiter
IPC: E01B29/28
Filed: 1981-10-26
Abstract: The wrench for tightening or releasing the bolts which secure railway tracks to sleeper has a reversible motor, driven by compressed air which feeds a reduction gear (2) incorporating a torque limiter (3). A frame (5) attached to the tool body carries a wheel (6) at its free end, which allows the tool to be moved alont the track. The use of a remote air compressor feeding through a pipe (8) makes the machine portable and prevents the tool from being used manually when the compressor is turned off.

Patent FR-2494140-A1 (FR)
Inventor: JOST HANS
IPC: B07B1/15
Filed: 1981-11-17
Abstract: Such a bar screen (1) has a plurality of bar rollers (2) rotating one behind the other in the conveying direction and having bar discs (4) and spacing rings (5) located between them. The bar discs (4) serve to transport the stone material (4) passing on the bar screen. Between two bar discs (4) located one behind the other a space (T) is maintained. In order to avoid a crushing effect between the bar discs (4), the circumferential shape of the bar discs (4) is determined in such a way that the spacing (T) remains constant irrespective of the angular position of the bar discs (4). As a result, additional stresses in the bar screen (1) are avoided and a reduction in the drive power of the same is achieved.

Title: Process and device for dismantling irradiated rod clusters.
Inventor: MOREAU JEAN
IPC: G21C19/33
Filed: 1982-10-13
Abstract: The process and the device forming the subject of the invention relate to the dismantling of irradiated rods in nuclear reactors. More precisely, they relate to the separation of poison and/or plug rods and/or of other rods from a transverse supporting plate. The separation is performed using shearing by producing a relative movement of the support plate in translation or in rotation in its plane relative to a counterplate provided with holes through which the rods to be sheared pass. The process and the device are applicable to the dismantling of poison clusters employed in the cores of light-water nuclear reactors.

Patent FR-2518927-A1 (FR)
Inventor: GIELER JOACHIM
IPC: F16L31/02
Filed: 1982-12-24
Abstract: For producing hose lines with branches, as are required for example for the cooling system on motor vehicle engines, the generally smaller side hose is fitted in the vulcanisable raw state into a punched hole of the line hose and is bonded to the latter in an adhering manner at the same time as final vulcanising is carried out. According to known proposals, an improved pressure-resistant union is achieved by reinforcing the bonding area with fabric overlays. According to the invention, the precisely cut-to-size end face of the side hose is covered by a bearing ring of vulcanisable rubber. As a consequence of this, in the finished-vulcanised branch, the otherwise exposed reinforcing liners of the side hose are sealed off from the flow medium and consequently protected against the seeping-in of liquid particles having a corrosive effect in the long term.

Filed: 1983-04-07
Abstract: An energy-saving control arrangement (10) satisfying the most stringent sealing requirements is proposed. The directional control valve (12) of the control arrangement (10) is of seat-valve type of construction. A seat valve body (53) of this directional control valve (12), which seat valve body (53) has a fine-control bevel (66), controls in lifting position (44) the load pressure via a second control line (46) into a pressure space (32) of a control member (29) to enable a servomotor (15) to be controlled independently of load. In addition, the control member (29), assigned to the functions of a reversing valve and a pressure-compensation valve, is provided with an orifice (35) and part of a three-way flow-control valve (23) which supplies a second servomotor (16) with a constant flow. The simple control arrangement (10) of compact construction realises control of a first servomotor (15) independently of load at maximum tightness with the supply of constant flow to a second servomotor (16) with only one control member (21).
