Abstract: The invention relates to a method of controlling an apex flow in a hydrocyclone unit (9), and a control system for carrying out the method. The hydrocyclone unit (9) comprises a plurality of hydrocyclone separators (10) in parallel, and further comprises an inject chamber (21, 22, 23), base chamber and apex-fraction chamber common to all separators, an inlet (1) to the inject chamber (21) and an outlet (2, 3) for the base chamber (22) and apex chamber (23) respectively. The apex flow is controlled by automatically and substantially continuously detecting at a location in or adjacent the apex outlet (1) a flow parameter of the apex fraction, and comparing this sensed flow parameter value with a set-point value, and changing the setting of a valve (15) incorporated in a conduit (14) connected to the apex outlet (2) when the sensed value deviates from the set-point value, so that the flow parameter value of the apex fraction moves towards the set-point value.

Abstract: The titanium chips arising as scrap from the working of titanium parts are, for the subsequent use in fusion metallurgy, precompacted by passing them through the compaction chamber ending funnel-like in a slot and, after they have emerged from the slot, drawn in between counterrotating rolls and pressed in the roll nip to give a rod of a density from 1.5 to 3.5 g/cm<3>, preferably 2.4 to 2.8 g/cm<3>. Two possibilities for the further treatment of the rod thus produced are described: The rod can be heated under a blanketing gas to a minimum temperature of 600 DEG C and be further compacted at this temperature between further counterrotating rolls up to a density from 3.0 to 4.4 g/cm<3>, preferably 3.3 to 3.8 g/cm<3>; after subsequent cooling at least to about 400 DEG C, the rod emerges from the blanketing gas atmosphere and can be reeled or cut into parts of the length required for use in fusion metallurgy. In the second possibility, the rod is fed to a reactor under a blanketing gas and fused therein by means of a plasma jet or electric arc; molten drops fall to the bottom of the reactor, where they form a coherent metal cake. <IMAGE>

Abstract: An electronic musical instrument comprises a keyboard (11) for generating tone data or key codes each representative of a tone to be generated and a tone generating circuit (14) having a plurality of tone generating channels (#1 to #N). The electronic musical instrument also comprises a RAM (18) having a plurality of storing positions for storing the key codes each of which is assigned under the control of a central processing unit (CPU (17)) to a respective one of the tone generating channels to thereby generate a tone determined by the assigned key code. When a key is newly depressed on the keyboard - (11), each of the key codes stored in the RAM (18) is read therefrom and supplied to an envelope generator (19) which in turn generates data (EGL) representative of an amplitude of each of the envelopes given to the tones. The key codes read from the RAM (18) are also supplied to a ROM (22) to read therefrom weighting data. The CPU (17) modifies each of the envelope amplitude data (EGL) based on a respective one of the weighting data, and selects one of the key codes stored in the RAM (18) in accordance with the modified envelope data. Then, the CPU (17) replaces the selected key code in the RAM (18) by the key code generated in response to the new depression of the key.

Abstract: In a demodulation system comprising a demodulator (22) which demodulates a quadrature amplitude modulated signal into first and second sets of output digital signals by the use of a reference carrier signal (CA), a specific phase control signal is produced in a transient state by discriminating a plurality of areas and a plurality of zones defined on a phase plane of the modulated signal. The areas are defined by dividing the phase plane by both a pair of quadrant reference axes and a pair of auxiliary reference axes phase shifted by π/4 (radians) relative to the quadrant decision axes. The zones are defined along and adjacent to the auxiliary reference axes. First and second detection signals (S<sub>1</sub> and 8<sub>2</sub>) are produced by a read-only memory (35) as results of discrimination of the areas and the zones, respectively. The specific phase control signal is switched to a normal phase control signal produced in a normal state in the known manner. Alternatively, the first and the second detection signals may be supplied to a transversal equalizer (21) for controlling imaginary part weighting controt signals.

Abstract: A thermostatically operated valve uses a valve insert screwed into a tube-shaped stud at a valve housing. The valve insert comprises two spaced-apart valve seats which are located on opposite walls of a chamber provided within the valve insert series-connected in a flow direction with one seat forming a control valve seat and the other seat forming a shut-off valve seat. Between the valve seats, a valve closing body is arranged within the chamber for temperature control operation by a thermostat device. The outlet of the valve is connected to a chamber downstream of the shut-off valve seat and a throttling bore connects the chamber between both valve seats with the outlet of the valve. A removal of the thermostat device allows the valve closing body to be urged against the shut-off valve seat by a spring within the valve insert while maintaining a flow through the throttling bore.

Abstract: A color image copying system (10) includes a light modulator (12) that receives incident light rays emanating from a source (14) of light. The light modulator comprises a light dispersing apparatus (54) that disperses different wavelengths of the incident light rays to different locations on a focal surface (60). A filter mask (68) aligned with the focal surface transmits preselected wavelengths of the ultraviolet light and blocks light of all other wavelengths. Each of a set of light valves (86, 88, 90) receives a different wavelength of light transmitted by the filter mask and intensity modulates it in accordance with image pixel information provided by an information source (16). An optical focusing apparatus (56) focuses the intensity-modulated wavelengths of light to a relatively small location (20) on an image focal surface (22) which is aligned with a light-sensitive medium (24). The light focused at the location exposes the light-­sensitive medium to each of the wavelengths of light for a particular period of time determined by the image pixel information. The location to which the intensity-­modulated light is focused is sequentially aligned with adjacent regions of the light-sensitive medium in synchronism with the delivery of image pixel information corresponding to the adjacent regions. This process continues in pixel-by-pixel fashion across the surface of the light-sensitive medium to form a color image copy in a single exposure pass over such surface.
