Abstract: Iron powder of high compressibility and low bulk density is made by atomizing a stream of molten steel by means of a conical jet of water at a rate in excess of 10 cubic meters water per metric ton of steel, the half cone angle is between 40 DEG  and 60 DEG , preferably 45 DEG ; and air suction is provided in a region upstream from the cone, adjacent to the stream at a pressure of 0.02 to 0.20 bars below ambient, by means of a length adjustable tube extending down from the nozzle chamber. The powder is reduced at 1,000 DEG  C. to 1,200 DEG C., and the resulting cake is broken up to obtain a powder having a particle size distribution with a higher content of larger particles than the powder immediately resulting from the atomization.

Abstract: An end portion 6 of a first shaft 2 is provided with a flat 10 parallel to its axis and an end portion 12 of a second shaft 4 has an axial cylindrical bore 16 for receiving the end portion of the first shaft. A spring 24 is held in transverse recesses 20, 22 in the second shaft, and has a curved portion 30 which is engageable with the flat 10 to prevent relative rotation between the shafts. The spring may however serve to absorb torsional shock loads. This construction renders unnecessary the provision of a bore of D-shaped cross-section, or of a transverse clamp screw, as in some prior assemblies. <IMAGE>

Abstract: A method and an apparatus for testing and identifying electrically conductive discs, such as coins or equivalent. According to the method the effect of each coin on a magnetic field generated by means of coils is measured, the measurement result obtained in this way is compared with the reference value, and the coin is accepted if the measured value is close enough to the reference value. The reference value is determined on the basis of the effect produced by a preselected reference coin upon a magnetic field preferably of the same magnitude as the magnetic field to be measured. The magnitude of the magnetic field is measured in two directions at least substantially perpendicular to each other and the effect of the coin upon the symmetry of the magnetic field to be measured is taken into account by means of an additional coil placed at least substantially in the symmetry plane of the magnetic field to be measured.

Abstract: A safety belt reeling device comprises a winding reel (3) spooling a withdrawable belt, the reel being mounted on a rotatable shaft and being lockable against unreeling rotation by means of a blocking device, thereby to prevent further withdrawal of the belt, on sudden acceleration of the belt withdrawal. The locking takes place through at least one locking body mounted on an axle of the reel (3), the reel being so displaceably mounted in a housing (6) that the axle of the reel is displaced out of a normal position and into a locking position against the force of a spring on sudden acceleration of the belt withdrawal. The locking body comprises at least one locking part (4) which comes into engagement with a counterlocking part (6b) on the housing (6) in the locking position. The locking part (4) and the counterlocking part (6b) are constructed in such a manner that the contact region between them in the locking state is disposed at the belt withdrawal side of the reel (3) in the region of the tangent (21) from the belt withdrawal point ofthe reel as seen in the withdrawal direction of the belt. <IMAGE>

Abstract: A piezoelectric element forms at least a part of a resilient vibrator which is firmly gripped at one end at a clamping point and is stressed by the tensile force of the thread at the other end, and which is prestressed substantially parallel to the stressing direction through a bearing surface acting at a point between its ends and rigidly connected to the clamping point. As a result, the piezoelectric element detects vibrations which are transmitted to the vibrator from its clamping point far less than vibrations which are transmitted to the vibrator through its free end by the tensile force of the thread. The transducer is therefore particularly suitable for installation in or on thread-processing textile machines. Its signal indicates not only the presence but also-with a moving thread-the travel of the thread, particularly when this thread is withdrawn overhead from a bobbin.

Abstract: An actuator for ejecting a store from an aircraft, with a pre-selected force vs stroke profile, is disclosed. The actuator comprises a cylinder and a fixed tubular member coupled to a source of fluid under pressure having a first array of orifices for flowing fluid into the cylinder. A piston assembly is provided, which is adapted to engage and eject the store. The iston assembly is slidably mounted within the cylinder and telescopically movable over the fixed tubular member from a first position, wherein the piston assembly covers a portion of the first array of orifices, to a second position, wherein the first array of orifices is uncovered. Typically, the pressure level of the source of fluid varies, generally as a function of the flow into the cylinder during the stroke of the piston assembly. Thus, the cross-sectional area and spacing of each of the orifices of the first array is selected to maintain a desired pre-selected pressure vs stroke profile within the cylinder upon the application of the fluid to the fixed tubular member, as the initially covered portion of the first array of orifices are uncovered during the stroke. Therefore, upon initiation of fluid flow, the first array of orifices meters the fluid into the cylinder at a rate sufficient to maintain the pre-selected pressure vs stroke profile therein. A system for varying the magnitude of the pressure vs stroke profile within the cylinder is provided, which comprises an adjustable tubular member coupled to the source of fluid, rotatably mounted in a bore within the fixed tubular member. The adjustable tubular member incorporates a second array of orifices which are in a one-to-one relationship with the first array of orifices. Preferably, an electric motor is provided to rotate the adjustable tubular member varying the overlap of the first and second array of orifices, such that the magnitude of the pre-selected pressure vs stroke profile can be varied.

In another embodiment, the RF signals are synchronized to the phase of the gating pulses by applying the output of a repetition rate oscillator to the RF oscillator.
