Patent FR-2257153-A1 (FR)
IPC: G04F5/06
Filed: 1975-01-08
Abstract: The very thin tuning-fork shaped quartz-crystal vibrator (15) is mounted in a casing (30) and comprises two metal rods (31) which are disconnected at two locations of the base of the vibrator which are touched by two conductive films of electrodes for exciting bending in their plane. These electrodes have a particular electrically advantageous configuration allowing such mounting. The two rods pass through the wall of the casing. A certain space remains between the rear side of the tuning fork and the wall of the casing, in which space the two said rods can bend in order to neutralise the stresses which, otherwise, would result from a difference in temperature coefficient between the quartz crystal and the material forming the casing. This component is particularly suited to miniaturisation, its vibrator being used as time base in an electronic watch.

Title: Rolled steel with improved properties in transverse direction - where selenium or tellurium is added to spheroidise sulphide inclusions
IPC: C21C7/00
Filed: 1975-10-02
Abstract: Steel is made to achieve improved isotropy of its mechanical properties after rolling, the steel contg. sulphur inclusions such as MnS. The novelty is that the morphology of the inclusions is controlled by spheroidisation of the sulphides, achieved by adding prescribed amts. of an element from the sulphur family e.g. Se or Te, which can be used at least as a partial substitute for sulphur. The element may be Se, with wt. ratio Se/S= 0.75-1.25, pref. 0.9-1.1 and esp. 1, the amt. of S being that at the moment of the Se addn. The steel is pref. desulphurised before adding the Se. Alternatively, the element is Te, with wt. ratio Te/S= 0.05-0.25, pref. 0.1-0.18 and esp. 0.15. The % S in the steel before adding the Te is pref. max. 0.035 wt.%. The resulting steel, obtd. using Se or Te, contains spheroidal inclusions. Instead of the inclusions which are elongated in the direction of rolling in conventional steel, spheroidal inclusions are obtd. so ductility and toughness in directions transverse to the rolling direction are improved.

Title: Fuel system for IC engine - has non-return valves between pump and carburettor and in bypass line
IPC: F02M37/00
Filed: 1975-10-06
Abstract: A pump (2) draws fuel from a tank (4) and delivers it to a carburettor. A non return valve (1) is placed between the pump (2) and the carburettor (3).

Title: Ladle for molten metal with curved base contg. flat recess - avoids very long outlet channel above sliding stopper
IPC: B22D41/24
Filed: 1975-12-19
Abstract: Container for cast metal, esp. a ladle, and designed to receive a sliding stopper has a cylindrical or barrel-shaped jacket and a curved base, the refractory lining on the curved base being thicker than the lining on the wall. The outside surface of the base is provided with a flat-bottomed recess so that the length of the outlet channel for the molten metal is reduced. The recess is pref. located at the periphery of the base, one side of the recess being formed by the edge of the base, whereas the other side is formed by two metal strips welded onto the base and reinforced by brackets holding the strips onto both the base and the recess. When ladles with a curved base are used, the lining on the base can be very thick in parts and, when a sliding stopper is located below the thick zone the outlet channel can be up to 1 metre long, producing excessive turbulence causing wear in the channel. The invention overcomes this problem.

Title: High speed plating of metal with nickel layer - using insoluble anode and controlling nickel ion concn in bath
IPC: C25D5/08
Filed: 1976-05-17
Abstract: A high speed Ni plating process uses an insoluble anode made of e.g. Ni which does not cause a passive state, and the supply of nickel ions into the bath is controlled by the detected pH value of the bath not by the amt. of dissolution of the anode, so as to adjust the pH and Ni ion density in the bath. The supplying Ni ion-contg. contg. soln. is prepared by reacting Ni flakes with a bath in a nickel ion supplying apparatus according to the detected pH value. Plating can be carried out with a high current density of 70 A/dm2 max. without losing the properties of the deposited Ni layer. It is possible to continuously seed the stable Ni plating bath soln. into a bath. When plating Ni on a solder layer, good adhesion can be obtd. between a solder and Ni plated layer without forming a copper strike between the solder layer and Ni plated layer.
