Abstract: PCT No. PCT/SE83/00451 Sec. 371 Date Jun. 29, 1984 Sec. 102(e) Date Jun. 29, 1984 PCT Filed Dec. 14, 1983 PCT Pub. No. WO84/02816 PCT Pub. Date Jul. 19, 1984.A method and apparatus in a telecommunication system for activating from idling state to active state. This system includes a digital transmission link consisting of a subscriber side containing a subscriber terminal (NT) and a station side containing a line terminal (LT) assigned to the station, the line terminal being connected to a clock pulse oscillator (CLM) constituting the master clock for the system, and the network terminal being connected to a local clock pulse oscillator (CLS) constituting a slave clock. Activation may take place either from the subscriber side or from the station side. In activation from the subscriber side an activation request signal (AR) is sent from a subscriber to the network terminal (NT) from which a cyclic bit pattern is sent to the line terminal (LT). The bit pattern is detected and sent as an activation request to the station which sends an activation order (AO) back to the line terminal. The line terminal sends frame formatted data and synchronizing signals back to the network terminal which then sends activation order to the subscriber and acknowledgement signals to the station. In activation from the station side, the activation order goes directly from the station without a preceding activation request from the subscriber.

Abstract: Data and associated validation information stored in a nonsecure location are verified as to integrity by cryptograph techniques. Verification activates a gambling system to operate in a gambler-responsive mode, and non-verification activates an alarm mode. The system is used in postal metering, electronic mail, electronic funds transfer and other source data processing systems. The validation information is formed by deriving a first value from the data according to a first relationship, and then deriving the validation information from the first value by means of a nonpublic derivation having an inverse function. The validation word is then associated with the data and stored in the nonsecure portion. Verification is accomplished by deriving 430 a first value from the data by the first relationship, and deriving 450 a second value from the validation information by means of the inverse function. The first and second values are operatively related 450 to determine system integrity. All relationships are one way function, in a preferred embodiment. In a preferred embodiment, the first and inverse second relationships are public and the second relationship is secret. <IMAGE>

Abstract: Workpieces which are formed by the build-up of weld metal are treated and cooled by directing a fluid such as water in a large stream so that rapid and intensive cooling of the surfaces of the workpiece is achieved by creating a laminar water flow. A water quantity is directed to reach the workpiece surface in a laminar flow and it is permitted to flow over the workpiece as the water is sucked off before it reaches its boiling point at the rate of flow to the workpiece and away from the workpiece being sufficient to prevent the formation of steam. The water which is employed is advantageously recooled to its initial temperature by the withdrawing effect created by an air fan.

Abstract: A rocket drive for space flights, having a ground thrust nozzle and an altitude thrust nozzle, which can be adjusted in the axial direction and is located in a drawn-forward position during launching and flight at low altitudes, but in contrast is connected to the rear end of the ground thrust nozzle during flight at high altitudes. The ground thrust nozzle is designed as an overexpansion nozzle up to an altitude of approximately 12 to 14 km, and produces an exhaust pressure of approximately 0.2 to 0.15 bar. Up to an altitude of approximately 12 to 14 km, the altitude thrust nozzle is located in such a drawn-forward position that a second, outer thrust circle is produced, and in this case the rear region of the altitude thrust nozzle together with the radially inner ground thrust nozzle as well as its drawn-in central thrust jet, which drives the outer thrust jet by means of an injector effect, forms a convergent-divergent supersonic annular nozzle for this outer thrust jet. At an altitude of approximately 12 to 14 km, the altitude thrust nozzle is moved back and axially connected to the ground thrust nozzle. The altitude thrust nozzle is designed as an overexpansion nozzle with respect to the environmental pressure prevailing at the altitude of approximately 12 to 14 km such that it produces an exhaust pressure of approximately 0.03 to 0.02 bar.

Abstract: The apparatus determines the position of the beam path (O) for a pulsed light beam (A) passing through an air-space by measuring the scattered radiation received by a detector device in a measuring station (F) situated on the side of the beam path. The detector device has a sensitivity lobe which has a given limited lobe width (2 DELTA  theta ) and which lobe can assume different angles ( alpha ) relative to a reference line (R). In the measuring station (F) the time distance between the front flank and the rear flank of the scattered radiation reaching the detector device, i.e. the pulse width or the pulse length of the scattered radiation, is determined in at least two different angular positions ( alpha ) of the sensitivity lobe. The position of the light beam path is then determined by means of the measured pulse widths in combination with the associated known angular positions of the sensitivity lobe.

Abstract: A reference generator and a number of input signal processors are provided. The reference generator generates a series of reference voltages, each half as large as the previous, the first of which is equal to the voltage range of the convertor employed. Each input processor converts one of several input signals to a bit-serial digital signal with the most significant bit first, using the common reference voltages. - In the switched capacitor circuit the input signal for each clock cycle is modified by subtraction of the actual reference voltage, and by addition of the previous reference voltage only if the foregoing initial bit is nil. A comparator is used, the output of which is nil if the modified signal is less than nil, and a digital control unit controls one of the switches in the switched capacitor circuit. This circuit has six switches, two capacitors and an operation amplifier.

The process is characterized in that, in connection with fitting of the horseshoe 1 to a horse's hoof 10, the horseshoe is only shaped to desired conformity with the hoof shape of the horse once the said layer 3 is in unhardened state, after which the horseshoe is hardened for subsequently fitting to the hoof of the horse. The horseshoe 1, which comprises a layer 3 of a thermosetting plastic, is therefore supplied with this layer in unhardened state. The layer 3 of thermosetting plastic is situated on the top side of the horseshoe and the horseshoe expediently has a wearing layer 2 of an elastic material on its bottom side. <IMAGE>
