Title: Wheeled arm to prevent tractor from overturning - is swing sideways from stowed position and locked by catch
Inventor: HOUDRE HENRI
IPC: B62D49/08
Filed: 1975-09-02
Abstract: The safety device for a tractor, to prevent it from overturning while working on a slope, such as when cultivating a vineyard, is an inverted L shaped arm (15) with a small wheel (21) mounted on the bottom which can be strung out to project from the tractor and act as a stop against the ground. Two brackets (11, 12) mounted on the chassis, carry two horizontal pieces of tube (11, 12) which in turn support a vertical tube (13). Over this is an outer tube (14) which can swing about their common vertical axis so that the arm (15) attaches to it can be swung round to a supporting position, away from the tractor. A plate (18) at the pivot point carries a latch (33) to engage pegs (23, 24) to lock the arm. This plate also carries latch arms which enable the arm to swing up clear of the frame when moved to the inboard position.

IPC: C08G59/50
Filed: 1975-12-19
Abstract: Use of cyanethylated cycloaliphatic diamines having 1 or 2 rings, and in which one amino gp. can be replaced if necessary by a H2N-CRR gp. with R = H or Me. Prepd. from an adduct of 0.75-1.5 mol. acrylonitrile or Me acrylonitrile with 1 mol. of diamine. Used if necessary in combination with other hardeners or accelerators to harden epoxide resins. As starting matls. can be used 1,4-diamino-cyclohexane, 4,41-diamino-dicyclohexane, 2,2-bis-(4-aminocyclohexyl)-propane. Also amines such as 3-aminomethyl-3,5,5-trimethylcyclohexylamine (Isophorondiamine), 2-aminomthylcyclopentylamine and Menthandiamine. Adducts prepd. esp. with mol. ratio 1:1, result in hardened liq. epoxide resins of low stress, and low susceptibility to shrinkage and cracks. Martens values of 90-100 degrees C and low water absorption attainable. A considerable redn. in peak temp. at hardening is obtd. when compared with use of prior art adducts.

Patent FR-2318477-A1 (FR)
Title: Master sound recording discs for gramophone record mfr. - where recording is cut directly into a metal or alloy disc
IPC: G11B3/70
Filed: 1976-07-15
Abstract: The master disc is pref. made of an alloy of non-ferrous metals, esp. using tin, lead, aluminium, silver, copper, and/or indium. Improves the fidelity of the recording and also simplifies the complicated series of operations normally involved in the plating processes used for record mfr. Master discs are usually made using a thin disc of aluminium coated on both sides with a lacquer, in which the recording is cut using a stylus surrounded by a small heater coil which facilitates cutting, but the heat alters the plasticity of the lacquer and the fidelity of high-frequency signal recording. By using a metal or alloy disc with no lacquer, the dimensions of the cutter stylus can be chosen so no heater coil is required, and fidelity is improved together with the signal/noise ratio. The metal disc can be cut with a diamond cutting stylus and reduces the number of plating operations normally employed in the electroforming of the stamping negatives used to press records.

Title: Vehicle endless tracks hydraulic tensioning device - with supply to tensioning rams determined by pressures across drive pumps
IPC: B62D55/30
Filed: 1976-08-09
Abstract: A hydraulic tensioning device for the endless tracks (7) of a tracked vehicle, comprises hydraulic rams (3) acting on the shafts (5) of the drive sprockets (6) or the idler wheels. The drive sprockets are driven by hydraulic motors (11, 11') supplied by variable output pumps (9, 9') and the inlet and outlet pressures of the drive pumps are sensed to control thee supply to the tensioning rams. The pressures across the pumps are compared by comparators (12, 12') which are connected to a comparator (12'') supplying the rams. The comparators may be nonreturn valves. Stops (19, 19') are provided on the rods of the rams to limit slackening of the tracks when the pumps are stopped. A hydraulic accumulator (21) reduces shocks to the shafts (5). A pressure-release conduit is connected via a cock (20) to a reservoir (B) to relax the tension in the tracks.

Title: Automatic electronic system for drying out buildings - counteracts natural electric current caused by dampness
IPC: E04B1/70
Filed: 1976-09-28
Abstract: The automatic electronic system for drying out buildings has live electrodes implanted in the walls which produce an electric current which counteracts the natural electric current existing in the wall because of dampness. This current is monitored by detector electrodes. The live electrodes are located in small slots in the walls and sealed in with a cement and graphite mixture. They are connected to an inverter which is connected to earth and to a current source. In order to allow the wall to discharge the current it receives the system is only operated during the day and this is controlled by a photoelectric cell connected in series with the detector electrodes and to an alternating current source. The signals are amplified by an amplifier.

Title: Hand grenade with delaying fuse - has metal fragments surrounding charge and shaped to be ineffective on reaching thrower
IPC: F42B12/32
Filed: 1976-10-19
Abstract: The hand grenade has a fuse delaying bursting after the striking of the explosive firing cap, so as to ensure that the thrower is at a safe enough distance. Around the propulsive detonating charge and in a casing which disintegrates with the detonation is a charge of small prefragmented metal bodies. These have a mortal penetration effect at a predetermined distance from the bursting point considerably less than the safe distance. The fragments are shaped so that they are ineffective at distances in excess of 20m, the fragments having a lethal effect at distances up to 5m.

Title: Automatic wrench for tightening wheel nuts - has hammer on wheel driven by gears from crank or motor to strike spanner
IPC: B25B19/00
Filed: 1976-12-02
Abstract: The machine for tightening or untightening wheel nuts may be operated by hand or by motor, and has an orbiting hammer which repeatedly contacts a ratchet-spanner. The hammer may project from a wheel which rotates about a horizontal axis and a multiplying gear-wheel transmission may be provided between a crank-handle or a motor and the wheel. With each rotation of the wheel the hammer describes a circular arc, and the projecting lever of the socket-spanner makes a radial intersection with the lower segment of the hammer-path. The spanner has springs and a ratchet mechanism, to oscillate relative to a vertical rest position and about the socket. The hammer thus, contacts the lever, causing it to pivot several degrees.
