Abstract: A master copy 6 of a software file has within it a predetermined block of data 8. When a copy of the file is made that block of data within the copy file is located and overwritten with data identifying the copy file 12. When an unauthorised copy file is found the data identifying the copy file can be read and the source of the unauthorised copy may be traced. The invention is particularly suited to use with software distribution over a computer network in which details such as the time the copy file was made and the name of the authorised user can be embedded within the copy file.

Abstract: A workout horse comprises a stationary base frame (15), a body portion (14) on which a rider sits mounted on an upper support (27) which is movable relative to the base frame, and drive means interconnecting the base frame and the upper support for continuously reciprocating the upper support and thereby the body portion forwards and backwards relative to the base frame along an intended rotary path. For providing the body portion (14) with the simulated movement of a horse at one end of the upper movable support a rigid link (40) is pivotally connected between the upper support (27) and the base frame (15), the other end of the upper support being supported above the base frame by a separate linkage (43, 44) spaced from the rigid link in the direction of movement of the upper support, and the drive means is mounted offset from the linkage in said direction of movement and comprises two cranks driven by an electric motor(37), the first crank (49) being connected directly to the upper support to effect said reciprocal motion of the upper support, and the second crank (50) being connected to said linkage between the upper support and the base frame whereby substantially horizontal driving movement of the second crank effects vertical extension or contraction of the linkage (43, 44) thereby changing the attitude of the upper support (27) relative to the base frame (15), the combined action of the first and second cranks effecting a movement of the upper support and thereby the body portion which simulates the movement of a horse. 
     In a particular embodiment the horse is for use by polo players and the drive means effects a movement of the upper support (27) and thereby the body portion (14) which simulates the natural cantering movement of a polo pony.

Date Dec. 13, 1990.This invention relates to the production of hydroxy-terminated polymers in the 2,000-20,000 MW range suitable for use as prepolymers in curing reactions with isocyanates to produce elastomers. The process involves the continuous addition over periods of 25-50 hours of an oxirane (monoepoxide) or a mixture of an oxirane and an oxetane to a reaction mixture, consisting of stoichiometric excesses of oxonium ion-forming catalyst such as BF3-etherate and a diol initiator dissolved in an inert solvent. Under these conditions, chain extension of the diol occurs and the formation of cyclic oligomers and other impurities is minimised. The mole ratio of the initiator to catalyst is maintained at above 10:1 to suppress the formation of cationic terminal species on the growing polymer chain.

Abstract: Une pompe d'injection de carburant du type pompe distrubutrice présente un régulateur de vitesse (22) logé à l'intérieur (18) de la pompe, l'intérieur se trouvant sous pression de commande. Ledit régulateur de vitesse actionne un actuateur du débit d'injection (21), ainsi qu'un variateur d'avance hydraulique (30) communiquant avec l'intérieur (18) de la pompe, lequel règle le début de l'injection (SB), au fur et à mesure que la pression de commande augmente à l'intérieur (18) de la pompe, sur ''avance'', et au fur et à mesure que la pression de commande baisse, sur ''retard''. Pour la réalisation d'un début d'injection en fonction de la charge (LFB), un manchon de réglage (40) du régulateur de vitesse (22) pilote en fonction de la charge un étrangleur de décharge (45) à l'intérieur (18) de la pompe, lequel libère, suivant la position de réglage du manchon de régulateur (40), une section transversale différente de l'étrangleur vers un canal d'écoulement (46). Pour l'obtention d'un gaz d'échappement filtré dans toute la plage de charge, l'étrangleur de décharge (45) est conçu de sorte que la section transversale libérée de l'étrangleur soit égale à zéro ou très petite dans une position de réglage occupée en pleine charge (VL) par le manchon de régulateur (40), grande dans une position de charge partielle (TL), et de nouveau plus petite dans une position de vitesse à vide ou de ralenti (NL). Ainsi, le début de l'injection (SB) en vitesse à vide par rapport à la charge partielle est réglé de nouveau sur ''avance'', mais il n'a pas lieu aussi tôt qu'en pleine charge.

Title: Method for measuring mechanical torque.
Inventor: BERGER HUBERT
IPC: G01L3/22
Filed: 1990-11-16
Abstract: The invention relates to a method for measuring the mechanical torque on the shaft of an asynchronous machine supplied by a current or voltage rectifier with an intermediate circuit and coupled with a machine or engine or a test object, preferably an internal combustion engine. Values of the current (Id) and voltage (Ud) in the intermediate circuit of the rectifier (1, 2) are measured. The actual power (PKZ) in the intermediate circuit, averaged over a selected time-interval, is derived from these values. A modified rotary field power (P &cir&  &tilde& D) is derived by subtracting from PKZ all power losses (VWR) in the inverse rectifier (2) and the electrical and mechanical power losses (VASM) of the machine (3), with the exception of the rotor copper losses of the fundamental oscillation (VCu2,1). The modified rotary field power (P &cir&  &tilde& D) is divided by the angular frequency ( omega S) of the fundamental oscillation of the stator of the asynchronous machine (3), referred to the number of pole pairs (p), which can be derived from the electronic control and regulating system (4) of the rectifier (1, 2). This value is equated with the mechanical torque (Mm) reduced by the acceleration torque calculated from the moment of inertia (Jp) and the change in rotational speed (d omega m/dt). The advantage of this method is that the rotor copper losses of the fundamental oscillation, which are very difficult to determine because of their temperature dependence, can be neglected in the determination of the shaft torque.
