Abstract: A method of preparing an intermediate composition for the production of silicon or silicon carbide, wherein silicon dioxide particles (quartz sand) are coated with carbonaceous material in a fluidized bed from which the coated particles are extracted as they fall to the bottom of the fluidized bed by virtue of an increase in mass by the coating process. The carbon in the coating should be stoichiometrically equivalent to that required for the ultimate reaction of the silicon dioxide to form either elemental silicon or silicon carbide.

Abstract: The control centre (1) is connected to all connected devices for controlling or monitoring, briefly called controllers (3), by means of a two-conductor data bus (2) which is only fed with voltage from the control centre (1). Each controller (3) and the control centre (1) have a receiving and a transmitting device (7, 8) for messages. Each transmitting device (8) consists of the series circuit of a fusible link (12), a transistor (13) and an inductive resistance (14). The voltage UH is present as a digital H on the data bus (2). When the data bus (2) is loaded with a low impedance by one of the transmitting devices (8), the voltage drops to UL as a digital L. A disturbance by continuous low-impedance loading of a transmitting device (8) prevents any exchange of messages but also causes the control centre (1) to feed in a higher power to the data bus (2). This destroys the corresponding fusible link (12) and enables traffic with the remaining controllers (3) to be continued. <IMAGE>

Abstract: Various techniques are disclosed for controlling the operation of a workpiece inspection procedure using a battery operated probe to contact the workpiece and transmit information back to a control in a machine tool system. In one embodiment (Fig. 2), battery power is applied to the probe transmission circuitry in response to a flash of infrared radiation sent by unit (40) and detected by a photodetector (48). In another embodiment (Fig. 3), the probe is turned on by touching the probe against a reference surface (60). In both embodiments, a timer is provided to automatically disconnect the batteries after a predetermined time period. In such manner battery life is prolonged. The unit (40 or 40') acts as a receiver for the probe information which is transmitted, as infrared radiation, from LED's (50-54) on the front surface of the probe. <IMAGE>

Abstract: The equipment is located in a heat-insulated chamber resting on two sills which in turn are located on frost-free ground. On the walls of the chamber are suspended facade plates with an adequate gap for air exchange. The gap is required to be approx. 10 cms so that air flow is not arrested by friction against the wall or plate. Gable points are formed as broken-through screens, and through them passes warm air rising in the gap. - To increase cooling, the plates are painted white or other light colour, thus increasing sun ray reflection, and reducing energy absorption. A cooling and heat coil is incorporated, comprising a tube filled with fluid circulated by a pump. The fluid absorbs or emits heat in the chamber, and transfers it to the surroundings.

Abstract: The chain links are bent in a single bending station, using a single mandrel. Pieces of wire of a given uniform length are bent into a V-shape between a holder and a suitably shaped recess in the mandrel. A wire feed sleeve and a wire receiving sleeve are disposed opposite one another defining a wire path between the holder and mandrel. Wire guides having guide surfaces guide the wire in its feed path from the feed sleeve to the receiving sleeve. The receiving sleeve has an abutment member provided with a support surface which, with the feed sleeve, prevents the leading and trailing ends of the wire piece from moving in a direction perpendicular to the direction of wire feed during the V shape bend. The two sleeves, each of which is formed together with a bending tool, are then retracted to free the wire ends, and the bending tools are moved perpendicular to the wire feed direction to bend the wire ends around the mandrel into a C-shape. The wire ends are then bent around the same mandrel to bend the wire ends into an O-shape to close the link.

Abstract: A computer-controlled device for correction of output signals from incorrectly operating sensors. Industrial sensors generally deliver in course of time erroneous signals due to coating, wear etc, which makes it desirable to compensate for the errors. These desires have been provided for by this device intended to be placed adjacent the place for determination or sampling of the measured medium. The correction is carried out by letting the device measure the signal of the sensor, after pushing a button and compare this with a result obtained by the determination/sampling, which has been fed in via the key-board of the device. The device calculates the correction term, by which the input signal to the device shall be multiplied so that the output signal will correspond with the reality. A corrected signal is delivered to a regulator, indicating instrument or the like.

Abstract: The present invention refers to a threaded coupling for percussion drill rods having a diameter of 30 - 40 mm, comprising an external rod thread and an internal sleeve thread, the longitudinal section of said threads having continuously curved tops and bottoms. In threads of the type mentioned above it is desirable to be able to tighten them to a relatively high degree because otherwise the thread coupling loosenes when used in hydraulic percussive drilling machines of a high frequency. Significant for the thread coupling of the present invention is that the pitch (S) is 7 - 11 mm, the radii of curvature (R1 - R4), at least for the portions of the tops and bottoms located immediately adjacent the contact shoulder, are 3 - 5 mmm, and that the threads have a height (H1,H2) of 1.2 - 1.6 mm.

Abstract: The optimum parameter control method uses a computer to continuously determine with the aid of a mathematical model (MODEL) set up in advance, in dependence on the robot configuration and load in question, the mass moment of inertia (Ji) of the axes, the coupled mass moment of inertia (Jij) and the moment (Mgi) caused by gravity. From the relationships between acceleration and deceleration and the drive motor torque for the different axes, the maximum available acceleration/deceleration for the axis is determined while assuming that maximum torque prevails for each axis. For each axis this value (STABCRIT) is compared with the maximum acceleration/deceleration value that may be allowed from the stability point of view. On the basis of the lower of these values, optimum gain (Kpi) is determined and set in the position controller and/or a path planning parameter.

Abstract: The measurement body comprises two concentric metal tubes, one inner and one outer (3), sepd. by a distance component of electrically insulating material. The two tubes are connected by leads to a vector impedance meter for measuring phase angle. The body is fitted in a section of a tube in which the fluid to be monitored is transported, or, alternatively, inside a tube or tank in which the fluid is stored. The fluid fills the space inside the inner tube and that between it and the outer tube. The ends of the inner tube may be blocked so that only the space between the two tubes is filled with fluid. Thus, a capacitor is formed by the measurement body, and the two tubes constitute its electrodes. When monitoring the compsn. of a fluid, a known high frequency alternating voltage is fed over the two electrodes, and the phase angle between the voltage and the resultant current is measured, it being preferable for the frequency of the voltage or current ot be in the interval of 250 kHz.
