Abstract: 1. Process for the controlled release of metered lubricating liquids or suspensions in applying a coating of lubricant to mechanically stressed zones of pressing tools in tablet-making machines, in which the lubricant solution or suspension is metered to one or more liquid valves (F) from an unpressurised storage container (V) by means of a pump (P) operating without pulsations, in such a way that the metering is in synchronism with the cadence of the table-making machine, characterised in that an under- or over- pressure prevailing at the pump outlet and measured against a rated pressure brings about a change in the times of opening of the liquid valves (F), or optionally changes in pressure may be equalised upstream of the pressure gas valves (L) by changes in the times of opening these pressure gas valves.

Abstract: A hydraulic elevator system 10 having an elevator car 12 in which car velocity V and car position L are determined by detecting the quantity Q of hydraulic fluid transferred between a hydraulic cylinder and a hydraulic fluid reservoir. The car velocity V is directly proportional to Q and the car position L is directly proportional to the integral of Q. The car velocity V, or quantity Q, is compared with a desired velocity pattern, or desired flow rate pattern, PG, and the difference is a control signal C which is used to control the quantity Q. The car position L may also be used to determine the distance-to-go to a target floor, which may be used to initiate slowdown and/or to calculate all, or selected portions of, the desired pattern PG.

Title: Method and device for adaptive digital cancellation of the echo generated in telephone connections with time-variant characteristics
IPC: H04B3/23
Filed: 1989-12-07
Granted: 1993-03-31
Abstract: A procedure is described for cancellation of the echo produced in telephone connections with electrical time-variant characteristics such as for example those affected by phase roll. The echo canceller obtained in accordance with the procedure which is the object of this invention produces an estimate of the echo signal by means of appropriate digital filtering of the signal originated by the far-end talker. The estimated echo is then subtracted from the actual echo. Filtering is activated by an IIR digital filter (FTR) whose adaptive coefficients are updated by use of an adaptive algorithm based on decimation of the square error. The high convergence speed of said algorithm in the calculation of the coefficient correction step allows a correct estimate of the echo even in case of connections affected by phase roll.

Abstract: The invention relates to a process and a means for representing structures (ST) which are predominantly biological, or have been technically produced. The process enables the representation of inhomogeneous structures (ST) in situ in real-time operation. It can be used to produce IR and NIR tomograms, and to determine the volumetric flow in capillaries and filters, and can be employed in medicine, biology and technology in order to observe and assess structures (ST), surfaces, volumes and volumetric flows in which chemical and physical processes take place. According to the invention, the IR light sources and receivers that are arranged in a one plane are guided as large-area radiators and receivers (SE) with respect to the object in the x-y-z direction, the large-area radiator radiating with a specific radiation cross-section and a specific intensity, the emitting IR diodes being driven with a peak current of preferably up to 1A at a pulse frequency of preferably up to 100 kHz, and the backscattering being detected. Together with the arrangement of the sensor (SE) for the large-area radiator/receiver, profiles, determined in real time, of the IR attenuation gradients of the volumetric elements permit an exact spatial assignment of the volumetric elements in the micrometre to centimetre range and a contrast representation of specific structures (ST). <IMAGE>
