Abstract: Cooking apparatus controlled by a programmed digital microcomputer for determining whether the cooking process is complete and for filtering the cooking medium when, for example, only one cooking process is complete. The apparatus also determines whether the cooking medium has been filtered and locks out the initiation of a cooking process after, for example, the completion of only one cooking process at least until the apparatus determines that the cooking medium has been filtered.

Abstract: At the time of expansion and accompanying kinetic degradation of a flowing stream of fluid, the flow is stabilized by forming at least two contiguous flow streams which consist of the same fluid but have a different velocity distribution and the two streams are then mixed. When applying the method to a valve provided with a so-called "hemispherical" closure member for compressible fluids, subsonic discharge nozzles are formed by cutting recesses in the valve seat downstream of the zone in which the valve closure member bears on the valve seat in the closed position. The subsonic discharge nozzles are disposed in alternate sequence with supersonic discharge nozzles formed by the opposite surfaces of the valve closure member and of the valve seat outside the recesses. When the method is applied to a multi-bore pressure reducer for compressible gases, a pressure-reducing plate is provided with low-discharge ducts in adjacent relation to high-discharge ducts.

Abstract: In order to attain the maximum permissible speed of a stepping motor and to achieve a substantial reduction in the time required to perform a predetermined number of steps, acceleration between the starting speed V.sub.o and the maximum speed V.sub.m takes place in the form of incremental increases .DELTA.V.sub.n in the frequency of the signal for controlling the speed of the motor at time intervals .DELTA.t which are all equal. All the speeds V.sub.n-1 +.DELTA.V.sub.n are precomputed by a microprocessor and the precomputed values are stored in memory. These values are read at each instant t+.DELTA.t during the acceleration period and in the reverse order with respect to the deceleration period. The curve velocity V is a function of time t is of exponential form with a negative exponent.

In order not to impair or damage the seal of the said table, the diode is fastened on a diode carrier support in a guide which is fastened at the rear of the table. The invention applies especially to sealed display tables.

Abstract: A hollow charge including a primer block with a reverse, integrated ogival screen with a triggering effect.

Abstract: A mobile mixing device for at least two products coming from storage containers in barrels equipped with internal kneading means, which can be rotated by a kneading head, via a disconnectable coupling, wherein the device comprises a fixed stand having two receptacles able to receive the barrels and a turret supported by the stand, so that it can rotate about a vertical axis, said turret having the storage containers, the kneading head, at least one tube connecting each of the storage containers to the kneading head and means for vertically displacing the latter an upper position permitting a rotation of the turret in order to bring the said head successively above each of the barrels placed in the receptacles of the stand and a lower position in which the kneading means of the corresponding barrel are connected to the kneading head by said coupling.

Abstract: A telescopic warhead for a submunition ejectable from a carrier projectile the explosive charge of which is made up of submunitions scatterable and housed in the front portion of the carrier projectile, characterized in that the telescopic head includes a telescopic sliding skirt formed of a plurality of cylindrical elements, which are preferably metallic. The telescopic warhead, during storage, does not reduce the inside space requirement of the carrier projectile which leaves the inner volume available in front of the explosive charge whether the telescopic warhead is in a storage configuration or in an expanded configuration.

Abstract: The invention relates to a step motor particularly for an electronic timepiece, comprising a stator whose two free ends constitute two pole pieces delimiting therebetween an air-gap in which is accommodated the rotor. Each pole piece is provided with a recess of cylindrical shape so that the axis of each cylinder is parallel with the axis of rotation Ar of the rotor. The two axes of the said cylinders are shifted from one another by a value comprised between 80.mu. and 200.mu. in a direction perpendicular to the plane defined by the axis of rotation Ar of the rotor and the main direction of the flux generated by an exciting coil associated with the stator. The radii of the rotor and the stator are in the order of about 800.mu. and 1500.mu. respectively.

Abstract: A support of soft material (4) has a fiber-receiving groove (5) in one of its surfaces (40). The groove is filled with a transparent setable liquid medium. A rigid link part (8) is pressed against the groove. Suitably prepared ends (11, 21) of two optical fibers (1,2) are inserted into the liquid-filled groove from opposite ends thereof. The medium is caused to set, and then the link part (8) is removed from the support. The optical fibers come away with the link part and the support mold is reusable. In a variant, the link part is stretched prior to gluing, and is allowed to return to its original length after the glue has set. This prestresses in the connection.

Abstract: A tubular material based on a fabric reinforced resin, said material comprising layed up fabric layers, the inside and outside layers consisting of bidirectional braided sheaths, said latter two layers sandwiching an intermediate, unidirectional braid consisting primarily of parallel, longitudinal yarns at least 10% of which have a high tensile strength and the remainder of which are yarns of the same type as the yarns of said bidirectional braids. An application in the construction of a bicycle frame is described.

Abstract: Blood products and other substances colored by tetrapyrrole compounds such as porphyrins or metalloporphyrins, in an aqueous solution, are decolored by contacting the aqueous solution with an adsorbent selected from among alumina, magnesia, and magnesium silicate, and the resulting colorless solution is then collected. The solution to be decolored can be adjusted to a pH of 2 to 6, and can be at a temperature in the range of 0.degree. to 60.degree. C., but is usually decolored at ambient temperature.

Abstract: A robot intended to the assembly of constitutive parts of objects comprises at least one working head (4) provided with a tool (8) effecting above a working area (9) motions controlled by a program according to at least three degrees of freedom and, within said working area (9), a device (14) providing for the accurate positioning of the parts to be manipulated in predetermined positions and orientations. It is characterized in that it comprises at least one removable preformed receptacle (17) providing for the collective transport of parts to be assembled to or from the working area (9), said receptacle being configured to maintain with a certain tolerance said parts in relative positions and orientations similar to those determined by the device (14) and arranged to cooperate with the latter. Assembly process implementing a robot such as hereabove defined and its application to the assembly in series of constitutive parts of objects.

Abstract: A set of construction elements for erecting three-dimensional structures comprises hollow structural members used either as posts or as longitudinal beams and also comprises hollow assembly blocks provided with a series of openings in different orientations. The projecting head of an attachment end-fitting mounted within the end portion of a structural member can be latched within each opening of the assembly block. The attachment end-fitting of each structural member is mounted for displacement in axial sliding motion within the interior of the structural member. A movable locking wedge is placed transversely within an attachment end-fitting and inserted through corresponding openings of the respective structural member. Rigid attachment of the structural member to the assembly block is achieved by clamping the edges of the assembly block opening between the flanges of the projecting latch-head of the attachment end-fitting and the end of the structural member.
