摘要： A switching device for providing electrical making or breaking at a cross point (Fig. 7) among a plurality of cross points, which are arranged in a connection matrix with a plurality of incoming conductors (x) and a plurality of outgoing conductors (y) to each intersection point. An incoming conductor (x) and an outgoing conductor form a first and a second contact surface (61a and 51, 52) spaced from each other. The contact, which can be electrically conductive or non-conductive, is achieved by one or two balls (1, 2) which are moved with the aid of control means, e.g. a pin (S12). In one embodiment for providing contact between a plurality of incoming wire pairs (x, a, b) and a plurality of outgoing wire pairs (y, a, b) the balls (1-4) are arranged in pairs in a plurality of cavities (H1-H4) in a connection block (K) and are moved to their respective positions with the aid of the pins and rods (9) in the cavities. An operating means (M) with lifting plates (L1, L2) and combination plates (K1-K5, K2-K6) for selecting what balls which are to be moved by the pins are described.

摘要： The invention relates to an overvoltage protector with spark air gaps. The protector is intended for such terminal blocks which have a plurality of connectors insulated from each other for connecting a plurality of electrical conductors. The protector (3) has one or more earth electrodes (4) for connection to an earth conductor and a plurality of protective electrodes (5) for connection to the connectors of the terminal block. In the overvoltage protector the earth electrodes and protective electrodes are arranged insulated from each other and with intermediate spark air gaps. The earth and protective electrodes are formed (14, 15, 16) and situated relative each other in the overvoltage protector such that the nominal d.c. excitation voltage between earth electrode and any protective electrode is substantially equally as great as the nominal d.c. excitation voltage between this protective electrode and any other protective electrode. The overvoltage protector is utilizable as lightning protector for telecable networks withstanding an overvoltage in the order of magnitude 10 kV or more.

摘要： The invention relates to a pin (21) for connecting an electrical conductor (2) to a PCB (4). The pin has a first part (24) thrust into a hole in th PCB and a second part (26), to which the electrical conductor (2) is connected by a sliding contact (8). The cross-sectional dimension (d2) of the second part (26) is greater than the cross-sectional dimension (d1) of the first part (24), and between these parts the pin (21) has a shoulder (27) with sharp edges. The hole in the circuit board is coated with metal which is connected via tabs (22) to electrical conductors (3) of the PCB (4). The pin (21) is soldered in the hole with the aid of soldering metal (25) and flux. When the flux is heated it creeps along the surface of the pin. During soldering, the shoulder (27) with the edges prevents the flux reaching the second part (26) of the pin (21), the second part having contact surfaces (29) on the pin (21) against the sliding contact (8) and where the flux would be a contact resistance. The pin (21) has the advantage that its first part (24) is narrow and that the tabs (22) can have a small outside diameter. There is thus created room for a large number of conductors (3) between two adjacent pins (21).

摘要： A data processing system executes two instruction sequences in an order determined in advance. With the aid of instructions a main memory (1) common to both sequences is activated for data information reading/writing. Increased data handling capacity is achieved in the following manner: both sequences (5) are executed in parallel to start with. During execution of the first sequence the main memory is prevented from being activated for writing due to the second sequence write instructions (37, 39, 41). A write address and data information included in a write instruction (49, 50) associated with the second sequence are intermediate-stored. The intermediate-stored write address is compared with the read addresses (68, 70, 73) of the second sequence, and data information is prevented from being read from the main memory upon likeness in addresses, the intermediate-stored data information (37, 38, 39, 41, 44) being read instead. An address included in a read instruction associated with the second sequence is intermediate-stored if this address has not been previously selected in conjunction with a write instruction associated with the second sequence (49, 50). The intermediate-stored read address is compared with the write addresses of the first sequence and execution of the second sequence (66, 74, 76) is restarted upon likeness in addresses.

摘要： A subscriber line circuit (1) is connected via a subscriber line (3a, 3b) to a telephone set (2). For a raised receiver the subscriber line (3a, 3b) is supplied with a line current (Is) by speech signal amplifiers (4), which are powered from a power source (VBB). The speech signal amplifiers (4) and their power-supplying amplifiers (7, 9 and 10) have large idling power, apart from the power fed to the subscriber line. To decrease this idling power, the subscriber line circuit (1) has auxiliary amplifiers (5) with low idling power for supplying the subscriber line (3a, 3b) when the receiver is cradled. When a call is in progress and the receiver is lifted, the line current (Is) has a relatively large value and when the call ceases and the receiver is replaced the line current (Is) decreases. This current decrease is sensed via a resistor (R2) by a loop sensing circuit (13), which sends a signal (S1) to a control circuit (14). The latter then sends signals (S2) and (S3) for connecting the auxiliary amplifiers (5) and disconnecting the speech signal amplifiers (4).

摘要： A method and apparatus for adjusting a digital equalizing filter (U) in a hybrid circuit in a telecommunication system for transmitting digital information in duplex on a single line pair with simultaneous adaptive echo elimination and adaptive elimination of noise caused by intersymbol interference, where a first and a second compensation signal (ê(t), î(t)), which are respectively dependent on the stored parameters of a digital balance filter (B) and the equalizing filter (U), are subtracted from a received signal (a(t) + e(t) + i(t)) to form a difference signal (r(t)) which is compensated for noise respectively caused by echoes and intersymbol interference, the balance filter parameters being corrected with the aid of a correction signal ( epsilon Bk) dependent on the difference signal (r(t)). The equalizing filter parameters are adjusted with the aid of a further correction signal ( epsilon Uk) formed by the balance filter correction signal ( epsilon Bk) and the first compensation signal (ê(t)) such that the further correction signal ( epsilon Uk) will substantially agree with the balance filtercorrection signal ( epsilon Bk), but obtain the value zero when the first compensation signal (ê(t)) and the balance filter correction signal ( epsilon Bk) are both positive simultaneously or negative simultaneously. There is thus prevented the correction sequence of the equalizing filter parameters when the balance filter parameters are changed in a direction such that the absolute amount of the estimated echo (ê(t)) increases.

摘要： An electronic fuse is intended to be triggered should the current from a load (LA) exceed a predetermined value. The load current is restricted first by a switch in series with the load, the switch being kept in a closed or open state by pulses from a pulse length modulator (PB). The pulse length of the modulator is controlled by a sensing circuit (AK) such that when the load current exceeds the predetermined value, the circuit sends a control signal varying as the load current, so that the closing time of the switch (OM) decreases with increasing load current. After a practically constant time the switch is thereafter set to a permanently open state.

摘要： A priority apportioning arrangement for computers that contain processors of two types, a high-priority type which can determine its priority itself in relation to processors of a second low-priority type when using a common bus. The arrangement contains a first logic circuit (20) which has its first input activated on a request for access from one of the low-priority units (3a-3h), its second input activated on a request for access from the high-priority unit (1) and its third activated during the whole time the bus is used and has two outputs for assigning the bus a low-priority unit or the high-priority unit. The arrangement furthermore contains a second logic circuit (40) with two inputs, of which one senses that the high-priority unit desires access and the other senses that this access can take place with delay, the circuit also having two outputs, of which one is for indicating to the first logic circuit that the access request from the high-priority unit is present, and the other for indicating that the bus is occupied. When the input signal to the second logic circuit indicates that granting the bus to the high-priority unit can take place with delay, the arrangement has time to grant the bus to a low-priority unit, but the high-priority unit still has immediate access to the bus after termination of the task of the low-priority unit.
