Patent FI-94691-C (FI)
Inventor: FUKAZAWA KAZUO
IPC: H04N5/907
Filed: 1988-08-05
Granted: 1995-10-10
Abstract: A television receiver includes a phase-locked loop (PLL) (226-232) which generates a clock signal (CLK) having a frequency of N times the line frequency and being phase-locked to the horizontal line synchronizing signal (HSYNC). The clock signal produced by this PLL has a frequency which tends to jitter between N+1 and N-1 times the line frequency. To compensate for this jittering in the frequency of the clock signal, phase alignment circuitry (236) is coupled to the PLL to align the phase of the clock signal to the horizontal drive signal (HD) produced by the PLL on the occurrence of each horizontal drive pulse. The PLL may also include a delay element (234) which delays the horizontal drive signal applied to the phase comparator of the PLL. This delay element effectively advances the phase of the horizontal drive signal and the line-locked clock signal with respect to the horizontal sync signal to compensate for signal processing delays imparted in the generation of the horizontal drive signal and the clock signal.

Abstract: According to the invention, winding machines having supporting rollers are so arranged that wound rolls (17) of small diameter can be ejected by being clamped between the ejection surface (13) of the ejector bar (9) and the supporting roller (2), which carries out the ejection, and by being lifted out of the supporting-roller bed (3) by a rotary movement of said supporting roller (2). In such a winding machine according to the invention, this is made possible in that the ejection surface (13) reaches the swung-round supporting roller (1) and in that its upper limitation in the swung-forward position extends as far as the region of the crown of the adjacent supporting roller (2). 
<??>In a winding machine of this type comprising a combined device (8) for ejecting wound rolls and for inserting new winding tubes (5), in which the ejection surface (13) of the ejector bar (9) ends at a distance from the supporting roller (1) and the tube-inserting element (14) releases the tubes (5) through the free space between the ejection surface (13) and the supporting roller (1), the ejector bar (9) has an ejection surface (13) which can be moved or extended in the rest position of the ejecting/inserting device (8) in the direction of the swung-round supporting roller (1).

Abstract: A transponder (10) that selectively provides both global and spot beam antenna coverage. The transponder (10) comprises a channel amplifier (12) and an antennafeed network (18) that includes coupler means (20) for coupling energy into a plurality of power distribution networks (21, 22) that feed a plurality of antenna radiating elements that form a beam that illumates the desired coverage area. A variable power divider (13) is coupled to the amplifier (12) that variably couples power along two channel output paths. Each output path includes a matched bandpass filter (14, 16) and the second output path includes a phase delay circuit (15). Selective control of the ratio of the power coupled to the respective output paths, and the phase delay provided by the phase delay circuit (15), provides for selective coupling of the total power provided by the channel amplifier (12) to either the full set (26), or a selected subset (25) of the antenna elements which generates global and spot beams, respectively. A more complex version is described which additionally incorporates an N-channel multiplexer (30). The present invention may also be employed as an interface circuit that may be interposed between a transponder channel amplifier (12) and an antenna feed network (18) to retrofit existing transponders to provide for selectable beam coverage.

Granted: 2000-10-17
Abstract: An electric motor has first, second and third stator windings supplied by a source of alternating voltage having three phases A, B and C, respectively. A separate thyristor switch assembly couples each stator winding to an alternating voltage phase when said switch means is rendered conductive by a trigger signal. When the speed of the motor is above a first predefined level, the thyristor switch assemblies are triggered, in response to the polarity of the voltage between phases A and B being opposed to the polarity of back emf voltage induced across the third winding, to apply current through said first and second stator windings. However, when the speed of the motor is below the first predefined level, the thyristor switch assemblies are triggered, in response to the polarity of the voltage between phases B and C being opposed to the polarity of back emf voltage induced across the third winding, to apply current through said second and third stator windings. Subsequently when the speed of the motor further decreases below a second predefined level, current is applied through said second and third stator windings during every cycle of the voltage between phases B and C.

Title: Continuous mixing of elastomeric compounds
Inventor: HANDA PAWAN KUMAR
IPC: B29C48/92
Filed: 1991-10-24
Granted: 1999-12-07
Abstract: A method of making an elastomer masterbatch or a compounded productive elastomer stock is provided. A twin screw extruder is used to mix elastomer components in multiple mixing zones at controlled temperatures.      Elastomer and other ingredients are fed into the twin screw extruder continuously through precise loss-in-weight or volumetric feeders. The degradation temperature and/or cross linking temperature of the elastomer determines the rate at which the elastomer can be processed, since friction created during mixing heats the elastomer. Accordingly, the maximum rate of compounding is a function of the torque limit, cooling efficiency, and conveying capacity of the extruder.      The conveying capacity and torque limit are also a function of the size of the extruder. The viscosity of the elastomer compound in the extruder, as measured by a Mooney viscosimeter (ASTM D1646), is typically in the range of about 20 to 250 units (ML(1+4)100C).
