Abstract: 1. Method of transmitting information between a transmitting station and at least one receiving station (11), wherein electric analog signals are converted into luminous signals in a first semi-conductor laser transmitter (1) connected to an optical fibre (3), wherein the first semi-conductor laser transmitter (1) is associated with a second semi-conductor laser transmitter (7) connected to an optical fibre (8) to which there is applied a correcting analog signal generated from the electric analog signal applied to the first laser transmitter (1), by substraction of an electric analog signal supplied by a monitoring receiver (6), sensitive to the luminous intensity emitted by the first laser transmitter (1) in the optical fibre (3), and wherein there are individually detected, in each receiving station (11), in two different detecting devices (18, 19), the signals emitted by the said first (1) and second (7) laser transmitters, in order to supply two different electric analog signals, wherein, in each receiving station (11), the leading electric signal is delayed in a delay circuit (20, 21) in order to compensate for the difference in the propagation times of the two signals, and wherein the two different electric signals thus compensated are combined with one another in an appropriate mixing device (22), characterised in that, in each receiving station (11), on the one hand variable amplifiers or attenuators (27) and on the other hand an electric delay circuit (20) are influenced by means of a complex adjusting device (28) sensitive on the one hand to the level of reference carriers and on the other hand to the deviation between the signals detected by the detectors (18, 19), and a signal identical to the compensated emitted signal is restored by means of the mixer (22).

Abstract: A modulator (100) receiving an analog input signal and a switching signal for providing an amplitude modulated output signal. The modulator includes a differential input amplifier (20) coupled to a multiplier (32, 34) wherein the analog input signal is commutated through a load resistor by the switching signals that are supplied to the multiplier. A gating circuit (106, 108) is coupled to the multiplier whereby the analog input signal is commutated to a feedback circuit (104) coupled between the gating circuit and the second input (19) of the differential input amplifier. The feedback circuit produces an output for adjusting the bias potential atthe second input of the differential input amplifierto equalize the differential output currents therefrom when the analog input signal is set to a nominal zero level and the gating circuit is activated.

Abstract: An electro-optical device including a chiral smectic C, H or other tilted smectic liquid crystal disposed between flat plates treated to enforce molecular orientation parallel to the plates. The plates are spaced by a distance sufficiently small to ensure unwinding of the helix typical in a bulk of the material to form two stable states of the orientation field. The liquid crystal is switched between two stable states by reversing the polarity of an externally applied electric field to make a bistable light valve or other electro-optical devices.

Abstract: A piston-rack rotary fluid pressure actuator includes a housing (10) enclosing cylinder (11) in which is disposed a pair of pistons (12, 13) biased by springs (14 and 15) towards the centre of the cylinder. Each piston has a rack portion (16, 17) engaged with a pinion (19) on output shaft (18), and elements of low friction material (20, 21) are incorporated into the outer surface of the rack portions (16, 17) to take up forces tending to displace the rack-bearing portions towards the cylinder. Annuli (30, 31) of incompressible material keyed to the shaft (18) make rolling contact with runways (32, 33) on the rack-bearing portions and have diameters equal to that of the pitch circle diameter of the teeth of pinion (19). By this means contact is maintained between the low-friction elements (20, 21) and the cylinder and over-meshing between the teeth of pinion (19) and racks (16, 17) is prevented.

Abstract: Die Erfindung betrifft eine Thyristoranordnung mit mindestens vier Thyristorsäulen (S1-S4), die jeweils eine Serienschaltung von in Verbindungspunkten miteinander verbundenen Thyristoren (T11-Tn4) aufweisen. Dabei sind wenigstens alle p-ten Verbindungspunkte der Thyristoren (T11-Tn4) unterschiedlicher Thyristorsäulen (S1-S4) über Querverbindungen (Q11-Qn3) untereinander verbunden. In jeder Thyristorsäule (S1-S4) wechselt nach jedem eine Querverbindung (Q11-Qn4) aufweisenden Verbindungspunkt die Leitrichtung der Thyristoren (T11-Tn4) innerhalb der Thyristorsäule (S1-S4). Damit wechselt bei jeder Stromrichtung der Stromfluß zwischen den Thyristorsäulen (S1-S4) über die Querverbindungen (Q11-Qn4). Die Querverbindungen (Q11-Qn4) weisen im Vergleich zu den Verbindungen innerhalb jeder Thyristorsäule eine verhältnismäßig hohe Induktivität auf. Der induktive Spannungsabfall an den Querverbindungen addiert sich zur Durchlaßspannung bereits gezündeter Thyristoren, so daß die Zündung parallel geschalteter, noch nicht gezündeter Thyristoren unterstützt wird. Außerdem wird die statische Stromaufteilung durch den induktiven Spannungsabfall an den Querverbindungen verbessert.

Abstract: Tunnels are constructed by freezing soil and removing frozen soil between starting and end shafts of the tunnels. Tunnels are driven in an uncomplicated manner in rapidly changing soils without auxiliary construction means. A hole is bored in or near the planned axis of the intended tunnel between starting and end shafts. A soil freezing work pipe is inserted into the hole. The pipe is cooled by a cooling agent. The soil freezing work pipe continues to be cooled until an ice and frozen soil mass has formed around the work pipe, which frozen mass has a diameter which is larger than that of the planned tunnel. Frozen soil is subsequently excavated, leaving a frozen soil lining, which is immediately supported by a primary support lining or a permanent lining.
