Abstract: A fluid controller (17) is disclosed for controlling the flow of fluid to a steering cylinder (19). The controller includes a fluid meter (51) and a valving arrangement (49) including a valve spool (65) and a sleeve (67). The valving (49) defines a main fluid path including a main variable flow control orifice (121), a variable flow control orifice (123), the fluid meter (51), the steering cylinder (19), and a variable flow control orifice (125). In accordance with the invention, the valving (49) defines a dampening fluid path including a variable dampening orifice (133), the dampening fluid path being in parallel with the main fluid path to dampen pressure spikes in the main fluid path. The size of the variable dampening orifice (133), and the flow therethrough, is a function of the relative displacement between the spool (65) and sleeve (67), whereby the timing and amount of the dampening flow and the relationship thereof to the gain curve of the main fluid path can be selected as desired.

Abstract: A dip method of enveloping a battery plate with a microporous battery separator material involves first removing air bubbles from the plate by dipping the plate in an anhydrous liquid which may be a solvent or solvent/non-solvent solution, then dipping the plate into a second liquid comprising a polymer-solvent filler or polymer-solvent/non-solvent filler suspension After removal from the second liquid, the plate is dried by evaporation. The result is the formation of a microporous separator envelope about the battery plate. The plate may be dipped in a third liquid before drying. The third liquid may have a viscosity greater than that of the second liquid.

Abstract: Touch controlled zoom of a waveform display uses a touch screen for the display surface. Function buttons for moving or expanding the waveform display and for determining the axis of such movement or expansion operate in conjunction with a rotary encoder. Expansion, or zoom, is accomplished by contacting the screen overlying a point on the waveform about which zoom is desired. Such contact or activation of the expand function button results in movement of the rotary encoder providing a gain parameter to a zoom function. The zoom function operates on the waveform display in an exponential manner as a function of the gain parameter to expand or contract the waveform display about the zoom point according to the direction of rotation of the rotary encoder.

Abstract: A side-transfer device for flat knitting machines, comprises, above and parallel to the needle bed which is opposite to the needle bed involved in the transfer, two smaller semi-needle beds (FT-FTʹ), each having a length which is half the length of the main needle bed, and spaced from each other, at their inner ends, by such an extent as to be longitudinally movable in and out to the maximum distance contemplated in the transfer step. Each semi-needle bed is provided with transfer fingers (7) spaced apart as the needles of the needle beds and in such a number as to serve half a needle bed. The longitudinal movements of said transfer fingers are controlled by a single auxiliary carriage (8). Each semi-needle bed (FT-FTʹ) is supported by a slide (4-4ʹ) sliding on a guide (1) parallel to the needle beds of the machine, each slide being connected to means (17,18,19,20,17ʹ,18ʹ,19ʹ,20ʹ) which move it longitudinally for the transfer, rightwards, and leftwards. The guide (1), which also supports a guide for the auxiliary carriage (8), is connected to the frame of the machine so as to be pivotable about its longitudinal shaft (2) to enable, in an intermediate step, the transfer fingers (7) of the semi-needle beds to be raised and moved away from the needle beds in order to permit the transfer of the semi-needle beds to the extent required by the side transfer of the loops. The pivoting means comprises at least one respective lever (22-22ʹ) pivotable on each end of a fulcrum shaft (2) and which may be locked to said shaft. The levers present, at their end, a respective roller (29-29ʹ) which co-operates with a cam (30) carried by the carriage of the machine.

Abstract: A method and apparatus for the improvement of the resolution of digital signals. In digital TV signals which are transformed into a selected frequency range, irregularities in the pattern of the reproduced video signals occur because of rounding off errors, when the number of places is reduced during calculation of the coefficients. This is remedied by increasing the coefficients of the transformed signal values following at least one first coefficient, for example a uniform component, and reducing them again before inverse transformation. This invention can be employed in digital systems using block processing in which, because of a limited number of bits, a rounding off of the transmitted spectral coefficients is performed in the calculation.

Abstract: An output value related to an operating state of a controlled object is detected. An actuator serves to adjust the operating state of the controlled object. A target control quantity of the actuator is determined on the basis of the detected output value. The actuator is controlled in accordance with the determined target control quantity. The detected output value and the determined target control quantity are stored. A new target control quantity of the actuator is calculated on the basis of a vector of predetermined feedback gains and a vector of state variables. The feedback gains are determined by using a dynamic model which is an approximation to the operating state of the controlled object. The state variables are composed directly of the stored output value and the stored control quantity.

Abstract: Disclosed is a digital adaptive filter and a method of cancelling an echo component generated by a partial return of a transmission signal to a receiving side. The digital adaptive filter comprises: a main nemory unit (64) for storing a first echo replica which can be stored or read by using the parallel signal from a main tap unit (61) as an address signal, at least one submemory unit (65) for storing a second echo replica which can be stored or read by using the parallel signal from a subtap unit (62) as an address signal, and an adding circuit (66, 67) for adding the first echo replica and the second echo replica. The second echo replica stored in the at least one submemory unit (65) has a greater precision than the precision of the first echo replica stored in the main memory unit (64), and thus the accumulated error due to memory division can be reduced. Instead of or accompanied by the greater precision, the contents of the main memory (64) are updated directly based on the error between the pseudo signal and an input signal or based on a step size corresponding to the error, depending on whether the error is relatively large or relatively small, respectively.
