Patent EP-0369008-B1 (EP)
Inventor: FUKUDA MASAO
IPC: F16H59/08
Filed: 1988-05-24
Granted: 1994-01-05
Abstract: On décrit une transmission automatique pour une chargeuse à roues qui empêche de rétrograder même lorsque les freins sont appliqués pour réduire la vitesse du véhicule à proximité du camion de vidange (opération IV) pendant, par exemple, l'opération en V illustrée par la figure 4, afin d'empêcher la chute du chargement et d'effectuer l'opération sans à-coups. A cet effet, on détermine si la chargeuse à roues est à proximité (opération IV) du camion de vidange en se fondant sur le mouvement d'un bras de levage (1a) qui se déplace vers le haut lors de la manoeuvre de chargement. Lorsque l'évaluation est correcte, la vitesse du véhicule est maintenue. Un capteur (8) de position du bras de levage sert à détecter la position du bras de levage (1a) lorsqu'il se déplace vers le haut, et on détermine une valeur seuil permettant d'évaluer si le bras de levage (1a) est en train de se déplacer vers le haut. Un organe de commande (10) de la transmission est agencé de sorte que lorsque la position du bras de levage (1a) dépasse la valeur seuil, les rapports ne sont pas rétrogradés indépendamment de la vitesse du véhicule. La présente invention est particulièrement indiquée pour les transmissions automatiques de chargeuses à roues.

Title: Moulding method
IPC: B29C/
Filed: 1988-07-07
Granted: 1993-03-24
Abstract: A method of moulding complex composite articles having skin portions containing fibres to be injected with a resin and a core portion comprises providing one or more galleries in the core or fibre skin and injecting resin into the gallery or galleries whereby it is rapidly transmitted to all portions of the skin. The galleries overcome the resistance to flow created by the capillary nature of the fibrous layer and enable more rapid mould cycles to be employed and more complex articles therefore to be moulded.

Abstract: A key security system provides for the reproduction of secure keys by using distributed key generation data and a distributed encrypted prekey. The system encrypts program key generation data (17) with a program key prekey (18) in accordance with a first encryption algorithm to produce the program key (20); processes the program key (20) to produce a keystream (25); and processes an information signal (26) with the keystream to produce a scrambled information signal (27). The program key prekey (18) is encrypted with a category key (22) in accordance with a second encryption algorithm to produce an encrypted program key prekey (23). The scrambled information signal (27) the program key generation data (17) and the encrypted program key prekey (23) are distributed to descramblers. The descrambler within the key security system decrypts the distributed encrypted program key prekey (23) with the category key (22) in accordance with the second encryption algorithm to reproduce the program key prekey (18); encrypts the distributed program key generation data (17) with the reproduced program key prekey (18) in accordance with the first encryption algorithm to reproduce the program key (20); processes the reproduced program key (20) to reproduce the keystream (25); and processes the distributed scrambled information signal (27) with the reproduced keystream (25) to descramble the distributed scrambled information signal. The key generation data includes authorization data that must be processed by the authorization processor (35) in the descrambler in order to enable the descrambler. The use of authorization data as key generation data protects the authorization data from spoofing attacks. When more data must be protected than a single operation of the encryption algorithm can support, then additional data blocks are protected by chaining the system, wherein the output from one stage forms part of the input to the next. The key generation data for the program key includes a sequence number securely associated with the category key to thereby "timelock" program key reproduction to the use of a current category key and thus prevent an attack based upon the use of an obsolete category key.
