Patent SE-7905480-L (SE)
Inventor: FERRIEU G M M
IPC: H04Q3/72
Filed: 1979-06-21
Abstract: Subscriber line interface circuit for connecting a subscriber's telephone line to, for example, an automatic telephone exchange comprising a pair of amplifiers whose outputs are connected to the wires of the telephone line and which are fed by a d.c. voltage supply source. This supply source provides the telephone line with direct current via the amplifiers. In practice, the telephone line must be terminated by a symmetrical impedance of a prescribed value. To this end the interface circuit comprises means for determining the weighted sum of the current flowing through one and through the other wire of the telephone line such that the sum current is independent of the longitudinal currents in the telephone line. By means of an impedance, two antiphase feedback voltages are generated at the inputs of the amplifiers, these amplifiers then having a symmetrical impedance at their outputs.

Abstract: The bracket comprises a first catch 3 mounted on support member 2 for engagement with an edge portion of the central opening of the spare wheel so that the wheel may be pivoted in beneath the support member 2 and with an opposing edge portion of the central opening snap into engagement with a second catch 4 so that the wheel depends from the catches 3, 4. In this position, the first catch 3 is pivotal upwardly for urging the wheel against the support member 2. The first catch 3 has a rearwardly extending operating portion 16 pivotally connected to the lower end of a pressure arm 22. The pressure arm 22 is pivotally connected to a lever 20 which is fixedly disposed on a rotary shaft 19 of handle 18 so as to form an elbow-joint for locking the pressure arm 22 in its lower position and for lifting the pressure arm 22 to an upper position where the operating portion 16 and the first catch 3 are free. <IMAGE>

Abstract: An arrangement for modifying the dynamic range of an input signal has two series connected bi-linear stages with at least one cross connection feeding a signal component from one stage to the other stage to modify the action of the latter. In one embodiment a compressor has two bilinear stages 280 and 282, each with a linear main circuit path including an adding circuit (+) and a further path N1, N2 with non-linear characteristics providing a limited signal to the corresponding adding circuit, and a coupling circuit with transfer characteristic f(s) is connected to the output of the first further path N1 and injects a signal into the second further path N2 in order to improve such factors as reduction in noise modulation. A complementary arrangement applies to the expander 284, 286. In an alternative arrangement, the coupling circuit is a common control circuit for the series- connected compressor or expander stages, which reduces circuit complexity. <IMAGE>

Abstract: For determining the relative humidity of a highly moist gas, particularly air exiting from a wood-drying apparatus, there is used a humidity sensing arrangement having a capacitive sensor, whose capacitance varies with changes in the relative humidity of gas to which it is exposed, and means for generating an output signal proportional to the prevailing capacitance of said capacitive sensor. The capacitive sensor is exposed to a heated partial flow of the highly moist gas, and the output signal of the output signal generating means is modified in correspondence with the extent to which the partial flow has been heated.

Abstract: In a multi-coordinate measuring machine, a contact pin is movable relative to an upper part of a measuring head, in the X, Y and Z directions. The contact pin must be mounted so as to be displaceable from its zero position, and blockable in position in each of these directions. To simplify the construction, the mechanism for displacing and blocking the movements of the pin are combined in the form of an electrodynamic transducer for each of the three directions. The transducer is formed of a pair of aligned coils which are each associated with a permanent magnet.

Abstract: A device for burglary alarm protected doors intended to prevent unintentional unlocking of the lock mechanism of a door when the alarm circuit is operative, including a slide (3), displacably arranged at the outside door plane, arranged to be locked by means of an electromagnet (7) in a position extending across the key hole of the lock mechanism when the alarm circuit is operative. According to the invention, the slide (3) is arranged to influence an electrical swith means (8) when in a position extending across the key hole, thereby interrupting a voltage feed from the alarm circuit to the electromagnet (7). An initial displacement movement of the slide (3) in direction away from the key hole results in that the switch means (8) closes the voltage feed circuit to the electromagnet (7) from the alarm circuit, whereby the electromagnet (7) locks the slide (3) after an initial displacement movement against further movement away from the key hole As soon as the slide (3) is no longer manually influenced, the slide (3) after an initial displacement movement against further movement away from the key hole. As soon as the slide (3) is no longer manually influenced, the slide (3) returns to the position influencing the switch means (8), and the voltage supply to the electromagnet (7) is interrupted.

Abstract: A device for a woodworking machine (13) adapted at a number of consecutive working stations (14) for processing workpieces which are fed through the machine. The required working of the workpieces can be effected with at least one working station out of operation. The working stations are separated from each other by partitions (20) which extend between external walls (11), a roof (12) and a base and which are closely associated with the machine on either side of the working stations (14) and, like the external walls and the roof, are sound-proof. The tool or tools at each working station can be driven independently of the tools at the other working stations, and each compartment (22) defined by the partitions has a door (21) in the external wall (11). The path of travel of the workpieces through the machine is laterally limited by vertical walls and at the working stations the walls can be provided with covers for forming tunnel portions at these locations. A device is provided for indicating the state of operation in each compartment (22) and preventing unintentional activation of tools which are out of operation, such that a tool can be safely exchanged at one working station while workpieces are being processed at the other working stations.

The other normal installation switches, such as two-pole on/off switches, double changeover switches, series or intermediate switches are constructed from the basic module. In this case, such basic modules are combined and provided with a suitable housing cover. The housing base is provided with openings (10 and 11), which are arranged in two planes one above the other, for connection of leads and for the contact links (12, 13 and 14) which are required in the case of series and intermediate switches (Fig. 1).

Abstract: An electronic and magnetic valve (1) is inserted in the carburettor (2) with a float housing (3) and fuel intake (4). A 12v current feed (5) is provided via a starting key. By use of a key (6), the valve can be connected electrically. It can also be controlled electrically with a code system or infra-red emitter from a press-button panel or a portable radio. Fuel feed can be throttled by the valve built into the carburettor in series with the fuel line. In the rest position, the valve stops flow, and when it is fed with the voltage it is activated and fuel is allowed to pass. Voltage feed to the magnetic valve is closed and broken by means of an electronic code lock. The lock circuit, relay and valve are all fitted in the immediate vicinity of the carburettor input connection for fuel. The carburettor housing has a compartment with hollow spaces in its walls. These spaces are connected to the carburettor fuel contrainer, and are fitted with fuel. This means that forced removal of the lock arrangement is prevented, since the fuel housing in the carburettor would be damaged, rendering the carburettor unusable.
