Title: Extending conical base for flexible container - for cohesive particulate materials, for complete discharge through limited bore outlet
IPC: B65D88/16
Filed: 1969-02-12
Abstract: Container for holding and discharging a non-coherent but cohesive material has a flexible body (2) of e.g. thin rubber, fabric or plastic film, of cylindrical or prismatic form supported at each end by stiff hoops (5,10) or frames, where the base (6) is made of flexible material and carries an outlet (14) of smaller bore than the contai ner. A rigid radial flange (4) surrounding the outlet (14) allows the base to be supported level with clips (11) around the bottom end of the container body, but the flange can be disengaged the clip to allow the base to extend axially to produce a conical outlet (6) converging from the fall bore (12) of the container body. Used esp. for pendant (7.8) containers for storing and releasing measured total quantities of granular or powdered materials, which may agglomerate, e.g. ground rubber, pigments, plastics masterbatch materials, etc. with the base in the raised position, when the outlet cap (16) is removed, materials can discharge from the centre of the container at a limited rate, until an annular residue (A) is retained on the level base by the angle of repose (beta) of the material. The base may then be released to drop the remainder of the material. Any bridging of the material can be disturbed by axial oscillation of the extended flexible conical base.

Title: Non-reversible cct breaker - comprises encapsulated conductors fractured by remote control
IPC: H01H39/00
Filed: 1973-03-14
Abstract: A methyl methacrylate block is made up of one large and one small section joined by a zone having lowest resistance to shear fracture. Conductors of cold drawn copper are burred in channels passing through the fracture zone and both sections of the block. At one end the conductors form a loop and at the other the ends are connected to terminals. A hardening polyester resin bonds the conductors into the block. A piston powered by a detonating charge strikes the smaller of the two sections and causes a shear fracture at the block weak zone. The conductor has low tensile strength and coeff. of elongation and fractures cleanly. The ensures resistance to environmental hazards and an opaque resin in a transparent block facilitates a visual continuity check.

Title: Igniting charge for explosive shell - using two concentric ignition portions having different rates of ignition
Inventor: ROCHE GERARD
IPC: F42B1/00
Filed: 1973-10-30
Abstract: A missile or shell has an explosive war head or cylindrical shape with an ignition charge through the centre made up of two portions (A, B), each portion consisting of two concentric blocks (1, 2) shaped by a pouring or moulding process, so that one block (1) is shaped as a double cone, or diabolo shape, with the other block (2) around it, and with a hollow channel down the middle in which are located corresponding detonators (4). One block is of an explosive which has a speed of detonation different from that of the other, e.g. the speeds may be greater than 4000 m.per. sec and the other is less than 8500 m.per sec. This gives a simultaneous and even detonation over the whole surface of the charge.

Title: Sec. battery electrodes for nickel-alkali-cadmium cell - comprising active hydroxides supported on silver coated cellulose or plastic fibres
IPC: H01M4/29
Filed: 1974-02-26
Abstract: Sec. battery cell of the alkali/Ni-cd type comprises electrode supports made by pptn. onto a mat of cellulose or synthetic plastics fibres of a uniform layer of silver by reacting silver diamine with hydrazine. The coated fibrous mat is washed and dried. The anodes are then prepd. by cathodic treatment in a hot bath of nickel hydroxide contg. nickel ions with nicke anodes at about 60 degrees C using a cathode c.d. of about 450 mA/cm2. Green nickel hydroxide is held in suspension by forced circulation of the bath changes in black Beta-nickel hydroxide which together with nickel metal is deposited on the support. The process is much cheaper than the prior art. reaction with caustic alkalis, does not use so much nickel nor involve expensive sintering furnaces, and produced anodes are 30% lighter in weight, without loss of electrical conductivity or capacity. The conductive layers are very adherent, of high conductivity, do not contain water of crystallisation and hence do not undergo drastic change of volume during charging and discharging.

Title: Plastics object marking device - creates vacuum in hollow symbols bearing against object when soft
IPC: B41F17/10
Filed: 1974-04-02
Abstract: The characters are embossed on the plastic object when in the soft condition by creating a vacuum in the hollow symbols (12) in contact with the plastics object (14), thus sucking the material of the latter inside the symbols. Where the process is used for the marking at regular intervals of a very long object emerging from an extrusion press, a wheel (1) can be used, having the hollow symbols on the periphery and rotating as the object passes it in the tangental direction. When the objects are in contact, they are connected via an axial bore in the wheel to the vacuum source. The wheel can have an independent drive, rotating it at a speed to match that of the object, and it can bear against the latter by its own weight, counterweights being provided to regulate the application pressure.

Title: Titration to a predetermined equivalence point - with continuous and intermittent stages and varying rates according to position
IPC: G01N31/16
Filed: 1974-07-26
Abstract: A method of carrying out a titration incorporates relating the speed of operation to two stages represented by two reference signals. The titration is at first continuous and then intermittent and the timing is made proportional to the inverse of the difference between a signal detected in the titration flask and the values of the two reference signals, which represent a stage before the end, and the end, of the titration resp. The appts. for carrying out the process incorporates means of accepting the signal from the titration flask, inverting its sense of variation, selecting the reference voltage, measuring the difference between the titration signal and each of the reference voltages and applying the differences to an integrator and then to a comparator, which controls the application of one or other of the differences to the integrator and the progress of the titration. The titration signal may be received by a millivoltmeter, a pH meter, a conductivity meter a colorimeter or a thermometer. The process is more rapid and more precise under all conditions than existing processes, which may be rapid and precise, but for limited applications Comparison of a Karl Fisher estimation showed that the time taken was one half of that required in a conventional method while the degree of precision was five times greater.
Patent FR-2239640-A1 (FR)
Title: Sealing element containing hard spherical bodies - conforms to irregular surfaces without extruding through clearances
IPC: F16D37/00
Filed: 1974-07-31
Abstract: The multipurpose sealing element consists of a matrix of elastomeric material enclosing small rounded bodies, preferably spherical, of hard plastic or steel. In a typical example, an internally threaded outer tube employs a nut to compress the sealing element against the inner tube over the sealing surface. Because the hard spherical particles are too large to pass through the clearance between inner and outer tubes, the seal cannot be extruded. Thus fine tolerances are not required in order to obtain a pressure tight seal. The matrix containing the particles may be moulded as part of any desired seal shape.
