Patent WO-8500410-A1 (WO)
Inventor: LAMPARD ROBERT DOUGLAS
IPC: F02B19/14
Filed: 1984-06-29
Abstract: Un moteur à combustion interne possède une chambre de combustion principale (26) et une chambre de combustion secondaire (30) reliées entre elles par un passage (32) ayant un élément de commande d'écoulement (34) disposé à l'intérieur du passage pour faire varier de manière cyclique le degré de communication entre les chambres de combustion principale et secondaire. En utilisation, une charge secondaire d'air-carburant est d'abord allumée dans la chambre de combustion secondaire (30), l'élément de commande (34) bloquant sensiblement toute communication entre les deux chambres de combustion (30, 26). Ensuite, l'élément de commande (34) est déplacé pour permettre à la charge d'air-carburant d'allumage dans la chambre de combustion secondaire (30) de se déplacer au travers du passage (32) pour allumer une charge principale d'air-carburant dans la chambre de combustion principale (26). L'élément de commande (34) est mû d'un mouvement alternatif et possède une partie de tête (82) qui est déplacée depuis l'intérieur du passage (32), dans la chambre de combustion secondaire (30) pour effectuer l'ouverture de commnunication entre les deux chambres de combustion (26, 30).

IPC: H01R33/72
Filed: 1987-06-19
Abstract: Une prise de courant électrique (10) comprend une structure (12) soutenant des contacts électriques (20, 22, 24). Un logement (18) de fiches de connexion, dans lequel sont ménagés des ouvertures (100, 90), (102, 92) et (104, 94), est disposé en face des contacts (20, 22, 24) en vue de sa rotation. Le logement (18) de la prise de connexion est normalement verrouillé dans une position inactive, dans laquelle il recouvre les contacts (20, 22, 24), au moyen de languettes de verrouillage élastiquement abaissables (142) qui s'engagent dans les ouvertures (90, 94) du logement de la fiche de connexion. Lorsque les broches d'une fiche de connexion électrique sont introduites dans le logement (18) de la fiche de connexion, afin de passer à travers les ouvertures (104, 94) et (100, 90), les broches appuient contre les languettes (142), les abaissant afin de faire tourner la fiche de connexion et le logement de la fiche de connexion, ce qui permet l'alignement des broches de la fiche de connexion avec les contacts (20, 22, 24). Un mouvement ultérieur vers l'intérieur de la fiche de connexion permet la mise en contact des broches avec les contacts (20, 22, 24). Le logement (18) comporte une gaine de broche frontale (28), sollicitée élastiquement vers l'avant contre le corps de la fiche de connexion, afin de recouvrir les broches de la fiche de connexion, ladite gaine étant abaissée vers l'intérieur durant le mouvement de mise en contact de la fiche de connexion avec les contacts (20, 22, 24).

Patent AU-2001290036-A1 (AU)
Title: Encryption and identification method
Inventor: PELE LAURENT
IPC: H04L9/30
Filed: 2001-09-17
Abstract: The invention concerns a cryptographic method for transferring messages in encrypted form between two media A and B sharing a secret number E and hardly reversible functions fI(fJ (x)) = fJ(fI(x)). The method operates without public key and without shared private key through a dialogue consisting of several message exchanges. If the medium A wishes to exchange confidentially the message M1 with the medium B, the medium A randomly draws a number A1 and sends to B the number fE(fA1(M1)) = M2. B randomly draws B1 and calculates fB1(M2) = M3 which it sends to A. A calculates the reciprocal A1prime(=g(A1)) of A1 such that, A sends back to B fA1prime (M3) = M4. B calculates the reciprocal of B1prime=g(B1*E) of B1*E then calculates fBprime(M4)=(M5). Since M5=M1, the message has been exchanged confidentially. In another embodiment, A and B share a secret S, the message M1 comprises the secret S and B authenticates A by verifying whether M5 actually consists of the secret S. The invention is applicable in the case of a microprocessor card, a micro-computer and an electronic wallet.

Title: Method for plastic recovery of intrahepatic bile ducts after echynococectomy
Inventor: GAJDARSKI RADOSLAV N
IPC: A61B17/00
Filed: 1992-05-22
Abstract: The method is applied in liver-gall bladder surgery. It uses an autoplastic material - part of the fibrotic capsule of the cyst. The outflowing and loss from the gall bladder is controlled rigorously and easily. The prosthetic drain stays for up to 90 days. The opportunity for fibrosis and obliteration of the ducts is restricted. The edges of the damaged vessels are identified. Then a T-drainage is placed in the main bile duct. The vessel is then channelled in a proximal direction with an endoprosthesis through the T-drainage. The defect is recovered on the endoprosthesis with a model next to the cyst's capsule fibrotic tissue.

Abstract: ABSTRACT OF THE DISCLOSURE     A conference speech-channel forming method and its conference  telephone  system,   in  which  an  extension telephone  set  to  be  operated  by  an  operator  as  the chairman of a conference is connected in a predetermined logical  manner through a private branch exchange to a plurality of extension telephone sets to be operated by a plurality  of  operators  as  the  participators  of  the conference  to  form  conference  speech  channels  between these extension telephone sets.  That is, the conference speech channels are formed so that  (a)  a voice signal issued from the extension telephone set of the chairman operator is parallelly transmitted in one way to all the plurality of extension telephone sets of the plurality of participator operators, and (b) voice signals issued from the  plurality  of  extension  telephone  sets  of  the participator operators are added together at a voice adder circuit and then transmitted to the extension telephone set  of  the  chairman  operator.   In this  case,  mutual speeches  between  the  chairman  and  participators  are allowed  only  in  a  one-to-plurality  relationship.   In addition, mutual speeches between the participators other than the chairman are restricted.  Thus, even in the event where  the number  of  participators  in a  conference  is large,  the chairman operator can smoothly expedite the proceedings of the conference.
