Patent EP-0402711-A1 (EP)
Inventor: WENGER BRUNO
IPC: H03L7/089
Filed: 1990-06-01
Abstract: In the phase detector (PD), an invariable pulse (PR) with the length of half of a period of the clock signal (Tkt) and a variable pulse (PV) are generated for data bits D = '1' occurring, the difference between which pulses (PV - PR) is supplied as control signal to a voltage-controlled oscillator (VCO) which generates the clock signal (Tkt) in the correct phase. The circuit arrangement is constructed in such a manner that the pulses (PV) and (PR) are always generated in the correct length independently of the gate transit times of the logic chips used. <IMAGE>
Patent EP-0408045-A1 (EP)
Inventor: ROWAN TIMOTHY M
IPC: H02P3/18
Filed: 1990-07-13
Abstract: The application of electricity from an A.C. supply (A, B, C) to an induction motor (10) is regulated by a motor controller (20) and its thyristor switch module (14). The motor controller (20) includes a microcomputer (21), supply voltage zero crossing detectors (22, 23, 24) and motor back emf voltage comparators (25, 29). A computer program which is stored in a memory of the microcomputer (21) contains a routine for reducing the speed of the motor (10) and for slowing the motor to a stop. The speed of the motor (10) is reduced by initially using dynamic electrical braking to slow the motor to a speed at which it will not remain synchronized to the A.C. supply frequency. At this point, A.C. cycle skipping is employed to apply current to the motor (10) at an effective frequency which is a fundamental frequency component of the A.C. supply line frequency. The motor (10) becomes synchronized to this fundamental frequency component. If desired, the motor can be brought to a complete stop by discontinuing the cycle skipping and using the dynamic braking again for a given period of time. This technique provides a very controlled stopping of the motor (10) enabling equipment driven by the motor to be accurately positioned.

Abstract: The invention relates to a shredder with a catching device 16 which is suspended on the housing 2 of the shredder. In addition to the suspension hooks and suspension bolts, a securing means is provided in the form of a screw knob 32 with threaded shaft 34. The threaded shaft 34 of the screw knob 32 can be screwed into a threaded bore 28 of the housing 2. The end 35 of the threaded shaft 32 actuates a push-button switch 31 which closes the circuit when the catching device 16 is mounted so that the shredder or cutting mechanism with the rotating cutter can be activated. Before the catching device 16 can be removed, it is necessary to first release the screw knob 32 and thus to deactivate the shredder. <IMAGE>

Title: Thermal inter-cooler.
Inventor: NIVENS JERRY W
IPC: F25B41/42
Filed: 1990-01-23
Abstract: A non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device, and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor, which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements. A key factor in attaining the above advantages is the construction of the thermal inter-cooler that is so made that no restrictions are specifically inserted in the inter-cooler system, and that direct physical contact exists between the metal compressor inlet suction line and the metal (Cu) refrigerant hot line for optimum heat transfer, and as a result an increased volumetric efficiency and increased capacity occurs by a lowering of the pressure on both sides of the compressor.

Abstract: The invention relates to a method for measuring the phase of a phase-modulated signal (5). The signal (5) is measured at at least five different test points (P1-P5). From the associated measurement values (E1-E5), at least three sets of measurement values are formed in such a manner that a phase value  phi i arctran (Zi/Ni) where i = 1,2,...,m>3 can be calculated from each of the three sets of measurement values. For the signal having the frequency of the carrier wave, the same correct phase value  phi  is calculated from all three sets of measurement values. The essential factor for the method according to the invention is the finding that a correct phase value  phi  = arctran <IMAGE> can also be calculated from linear combinations of the Zi and the Ni. The factors ai are then selected in such a manner that the phase error has at least three zeros as a function of the phase stages between the test points (P1-P5). This significantly reduces the systematic errors in the phase measurement. The method according to the invention is particularly suitable for evaluating stripe images, particularly of multi-stripe images. <IMAGE>
