Patent FR-2225737-A1 (FR)
Title: Hydraulic cell for weighing machines - cannot jam and has pressure transmitted to remote site
IPC: G01L1/02
Filed: 1973-04-13
Abstract: The normal hydraulic cell used on weighbridges tends to jam when the weighing platform deforms under a moving load. The platform proposed has a chamfered edge to avoid this. Preferably the outer edge of the platform is formed as a segment of a sphere with the top, next to the load surface, being smaller than the bottom which rests on the usual membrane. The housing also has the sides opposed to the weighing platform shaped in a spherical form with the same centre taken, the sphere thus being of bigger radius. It is claimed that the usual gap can be made much smaller, thus avoiding trouble from objects falling down the slot.

Patent FR-2272164-A1 (FR)
Title: Mineral oil for cold rolling of aluminium - giving reduced fire risk and atmospheric pollution
IPC: C10M101/02
Filed: 1975-05-05
Abstract: Cold-rolling oils for Al, contg. as base oil a solvent-extracted low-aromatic distillate with boiling range 275-315 degrees C, viscosity 6.0-7.0 cSt at 20 degrees C, pour point of 0 degree C max. and flash point of at least 130 degrees C, derived from a paraffinic petroleum fraction, and with usual additives for this purpose. In the intermediate rolling stage during production of Al foil, in which the thickness of hot-rolled sheet is reduced from around 7 mm to 0.1 mm. The higher boiling range of the base oil, compared with that normally used, gives less vaporisation during rolling, with reduced fire risk and atmos. pollution. Statining or discoloration of the Al by the oil is reduced, and the higher viscosity allows the addn. of palm kernel oil to be decreased, or substituted by other fluid mixts.
Patent FR-2310898-A1 (FR)
Title: Support frame for mobile printing press - has rigid construction and pneumatic dampers with travel limited by stops
IPC: F16F15/027
Filed: 1975-05-15
Abstract: The mobile printing press is mounted on a rigid frame (1) which is supported on the chassis (22) of the vehicle using pneumatic dampers (5), and braced by struts (17) between the frame and the chassis. For transport the frame is lifted off the rigid chassis support by control valves (9) on the dampers. The amount of permitted travel on the dampers is restricted by cable or rubber block stops. The press is thus protected while travelling, especially when severe road conditions cause the chassis frame to twist. The pneumatic damping protects the press more than the vehicle dampers, which are necessarily harder.
Patent FR-2312716-A1 (FR)
Title: Sealed joint for water and gas pipes - has seal held by clamped flange and peripheral retaining ring
IPC: F16L55/178
Filed: 1975-05-27
Abstract: The sealed joint is intended primarily for water or gas pipes and provides good sealing even near elbows, and when the pipes are not perfectly circular. There are three main parts to the joint:- a flange (10) clamped to the downstream pipe (3, a cylindrical seal insert (13) and a seal retaining ring (15). The seal is positioned axially between the flange (10) and the end face (11) of the housing (5) fixed on the upstream pipe (2). Bot the flange and the retaining ring are formed from at least two sections which have radial flanges so that the sections can be bolted together, to clamp either the pipe or seal. The flange is first clamped to the downstream pipe at a distance (12) from the housing face just sufficient to clear the seal width. When the retaining ring bolts are tightened, it squashes the seal, forcing it into contact with the pipe, housing face and flange face.
Patent FR-2287359-A1 (FR)
Title: Safety interlocks for transmission - with electropneumatic blocking of gear change gate at higher speeds
IPC: F16H61/16
Filed: 1975-10-08
Abstract: The automatic transmission is fitted with a fail-safe electro-pneumatic interlock which monitors the engine speed, road speed and gear ratio setting. If the driver decides to change down then the system computes the new engine speed w.r.t. present settings and compares this with the preset safety limits. If the new speed is too high, i.e. the vehicle is travelling at a high speed in the one gear, then the interlock blocks the gear change process until the speed is adjusted. This prevents damage to the engine/transmission. The interlock also prevents the driver inadvertently from selecting the reverse gear.
