Abstract: 1. A circuit for decoding the vertical synchro pulses of a composite synchronization signal in an interlaced frame system, with the vertical synchro pulses comprising n positive pulses preceded by n negative front equalizing pulses and followed by n negative back equalizing pulses, these vertical synchro pulses and equalizing pulses having a frequency which is twice the line scanning frequency, characterized in that it comprises digital means for producing, on the basis of the composite synchronization signal, a rectangular signal (Q1 ) of half the line frequency, and a rectangular signal (Q3 ) of half the line frequency during the frame, except during the equalizing and the vertical synchro pulse periods, when the signal (Q3 ) has line frequency, the relative phase of the two rectangular signals depending upon the rank parity of the frame, and that it comprises a means (20, 22, 23, 24) for correlating these rectangular signals (Q1 , Q3 ) in order to generate decoded vertical synchro pulses, whose start coincides, substantially without delay, with the start of the vertical synchro pulses of the composite synchronization signal.

Abstract: The present invention relates to a method for thermal treatment of pearlitic rail steel. For increasing strength and wear resistance steels with the claimed composition are produced with a fine lamellar pearlite structure by heat treatment. During the first cycle the rail head portion is heated in a sufficient depth of up to 50 mm by means of a burner or an inductive system to an austenitization temperature of about 950 DEG  to 1050 DEG  C. Thereafter the heated head portion is cooled by means of compressed air in such a way that in a first step by blowing a large amount of air the temperature of the rail head portion is cooled within 10 to 20 s to 650 DEG  to 600 DEG  C. before the area of the pearlitic transformation. In a second step with throttled blowing compared to the first step in the area of the pearlitic transformation the rail head portion is cooled within 2 to 4 minutes to about 400 DEG  C. until finishing the pearlitic transformation. Then the rail head portion is again heated for 4 to 6 minutes to a temperature of about 600 DEG  to 650 DEG  C. and then rapidly cooled by means of water or other appropriate quenching media to a temperature of less than 100 DEG  C.

Abstract: Granular built detergent,compositions containing additive levels of organo-functional polysiloxanes are disclosed. The siloxanes are derived from poly-di-short-alkyl siloxanes by substituting part of the alkyl moieties by specific organo-functional groups, preferably amino-groups, with the proviso that the degree of substitution is in the range from 0.01 - 0.07. The granular detergent compositions herein unexpectedly provide through-the-wash softening benefits comparable to what can be obtained from the utilization of conventional cationic rinse- softeners. An additional benefit originates from the «dry-softening» feel of the composition herein as compared to the «greasy» feel conferred by conventional cationic rinse softeners.

Abstract: The invention concerns a tubular-tyre for bicycles and its assembly on a mounting-rim of the channel type - that is normally used in combination with the usual tyres having a beaded edge.The tubular-tyre of the invention has a tunnel-shaped carcass profile, in the plane of the cross-section, provided with a supporting-base which is substantially concave in the center and flat at the sides and with also having two sidewalls that join together in a substantially semicircular vault.The radially inner portion of thesidewalls is joined, at the supporting base (13), at an angle (b) of less than 90° and it is reinforced with a pair of reinforcing elements-one textile (10) and the other (8) either a textile fabric, or an elastomeric liner.The radially innermost portion of the tubular-tyre can be inserted into the channel of a flanged-rim - with thus constituting with said rim, after tyre inflation, a stable and inseparable assembly-that proves to be both suitable and efficacious - and with also guaranteeing a qualitatively high road-behaviour for the tyre.

Abstract: Method of and apparatus for two-wave explosive cutting in which the two-wave form for the shock wave produced by the detonation is achieved by varying the progress of the shock wave to the target in sections normal to the line of cut. This object is achieved, in one embodiment, by supporting a strip of explosive material (24) on a shock wave delay element (21) which spaces the mid-regions of the strip of explosive further from the target than the side edges of said strip. On detonation, the shock waves (25) produced by the side edges (22b, c) of the explosive (24) have less distance to travel through the element (22) than the mid-regions and thereby the classic two shock wave fronts (25a, 25b) situation is obtained in the target.

Abstract: A personal memory card system is arranged for use with a memory card which looks and feels much like an ordinary credit card. No ohmic electrical contact is required between the card and a reader/writer in an associated station for transferring data to and from the card and operating power to the card. The need for conductive contacts in transferring data between the reader/writer and the card is avoided through use of a capacitive interface formed when insulated metallic plates on the card are aligned in close proximity with corresponding plates on the reader/writer. Operating power is transferred to the card through an inductive interface formed when a flexible flat inductor embedded in the card is aligned in close proximity to another inductor in the reader/writer. Data to and from the card and power to the card are reliably transferred even after some time of normal use since there are no exposed metallic surfaces to corrode or to which particles may collect. In addition, the potential of damage to the card from electrostatic discharges is minimized since an insulator is provided between the electrical inputs to the card and any sources from which this discharge might occur. The personal memory card system is also arranged to permit an authorized user to selectively reprogram a memory card with new and different data as desired.
