First and third function passages extend from the torque control bore and are connectible to the first fluid motor, and second and fourth function passages extend therefrom and are connectible to the second fluid motor. A grooved, torque control spool is disposed in the torque control bore for sliding from a series operating position wherein the grooves connect the first port to the first function passage, the second function passage to the third function passage, and the fourth function passage to the second and third ports. The torque control spool is biased towards a parallel operating position wherein the grooves connect the first port and the first and second function passages in parallel and connect the second and third ports respectively to the third and fourth function passages for metered flow therebetween. First and second sensing passages are fluidly connected to the second and third ports and are selectively interconnectible via a direction sensing valve in the valve body with first and second pilot passages which are respectively connected to first and second ends of the torque control bore. The direction sensing valve operates to respectively connect the first and second sensing passages to the first and second pilot passages for the first direction of operation and interchanges the connection for the second direction of operation so as to move the torque control spool to maintain equal flow of fluid to the first and second fluid motors in either direction of operation.

Title: Method and circuit for the contactless measuring of direct and alternating currents, especially momentary current values.
IPC: G01R17/00
Filed: 1981-07-16
Abstract: A method and device for the contactless measuring of direct and alternating current, in particular current instantaneous values, by using a magnetic circuit having an air slot and a magnetic field dependent resistor through which a control current flows and a winding through which a measuring current flows. In order to provide a large measuring speed for picking up a rapid instantaneous value, for example, generated high current peaks, at least a further winding is mounted on the magnetic circuit, the voltage drops on the magnetic field dependent resistor are picked up and stored at the peak values or other typical values of the current to be measured. After completing the measuring current, the current in the equivalent current winding is increased and the already stored voltages corresponding to the measuring current are compared consecutively with the voltage drops on magnetic field depending resistor, corresponding to the increase in the amount in the equivalent current winding. At the same voltage values, the instantaneous current is determined by multiplying in the current in equivalent current winding by the winding number.

Title: System for communication by way of repeatedly transmitted messages, and stations for use in such a system.
IPC: H04W88/18
Filed: 1983-02-14
Abstract: A description is given of a system for communication between a transmitting station (30) and a receiving station (33) by way of a message which consists of a direct succession of a number of identical code words. Each message uses only a comparatively small part of the capacity of the message channel. Each code word has at least a predetermined minimum Hamming distance with respect to any other code word, including the cyclic transpositions of the latter code word. Therefore, for the detection and reproduction of a code word it is not necessary to realize word synchronization and a given category of errors can still be detected and/or corrected. The code words may concern, for example, a transmitter or program identification in a broadcasting system or a paging code for a receiving station in a system comprising selectively addressable receiving stations as in a paging system.

Title: A method to compensate for the truncation error in a sampled signal and a device for carrying out the method.
IPC: H03H17/04
Filed: 1984-11-23
Abstract: A positive signal value (+et) is added to positive signal samples (S1,S2) and a negative value (-et) is added to the negative signal samples (S3,S4). Since the fifth sample (S5) is zero, no correction value is added to it. In a subscriber line audio signal processing circuit, the polarity of a signal input to a digital adder circuit is sensed. The sensed polarity determines the choice of a stored digital representation of a value +et or -et in a memory. - The chosen value is output on one or other of a pair of bit lines leading to a multiplexer. According to the polarity sensed, a multiplexer selects the first or second bit line to provide the correction value to a second input of the digital adder. For simplicity the value et is chosen as an integral number, and represents the mean truncation error for the filter. (4/7) EPAB- EP-162076 B A method of compensating for the error which, in a digital signal with a given number of bits, occurs through truncation in a digital filter, particularly magnitude truncation, the signal being positive or negative relative to a given zero level, characterised in that when the signal is positive a positive first value is added to the signal, this value corresponding to a mean truncation error, and when the signal is negative a negative second value is added to the signal. (7pp) USAB- US4750146 A Positive and negative portions of a digital signal to be input to a filter are sensed and signals are provided representing positive and negative values of a mean error due to magnitude trucation of the signal in the filter. The positive and negative signals are respectively added to the positive and negative portions of the signal which is to be input into the digital filter. - The positive and negative signals are equal in magnitude. When the signal to be input to the filter has a value of zero no further signals are added. The average of the truncation errors produced by the multiplications in digital filter multipliers included in the subscriber audio-processing circuits. This average error is calculated in a arthmetic-logic unit.

Patent ES-8608945-A1 (ES)
Title: Method and apparatus for particle sorting by vibration analysis
IPC: B07B13/10
Filed: 1985-09-09
Abstract: A novel particle sorting system based on vibrations induced by impact against a strike plate is disclosed, wherein two strike plates in succession are used, the first to absorb kinetic energy from certain particles on a preferential basis due to particle composition, and the second to absorb the residual kinetic energy for analysis. Vibrations arising in the second strike plate due to particle impact which meet preset criteria corresponding to undesired particles are used to actuate an ejection system which sends an impulse to the offending particle, deflecting it from its otherwise undisturbed trajectory. Also disclosed is an analyzing circuit which combines two or more waveform features of the vibration signal in an algorithm such as a ratio, to provide an unusually high sensitivity for discrimination among the particles. In addition, the need to form a single file of particles before they can be put through the system is avoided by the use of a curved surface to convert the particle mixture to a free-falling monolayer, and by sensing impacts of the second strike plate in a region-specific manner.
