Title: Successive screw feeder driver
Inventor: MURO NARAHIKO
IPC: B25B23/04
Filed: 1996-07-05
Abstract: A successive screw feeder driver capable of using, as a single machine, plural types of screws of different lengths, capable of finely adjusting a screw driving position, and further capable of coping with a difference in the mounting position of a belt-like member of a screw chain. A screw driving bit (7) is connected detachably to a screw driving mechanism (3), and a screw feed mechanism (6) which is slidable longitudinally is connected to a front portion of the screw driving mechanism (3). An adjusting mechanism (23) for adjusting a longitudinal position of the bit (7) is constituted in the screw driving mechanism (3).      A screw feed means (24) is constituted in the screw feed mechanism (6) for feeding screws arranged side by side on a screw chain (9) up to a screw driving position where each screw is driven with the bit (7), in interlock with the screw driving operation performed by the bit (7). In the screw feed mechanism (6) are formed a plurality of guide passages (30) for the screw chain (9) so as to permit replacement and loading of plural screw chains (9). Further, a front-end block (12) having an abutment surface at a front end thereof is constituted in the screw feed mechanism (6) so as to be slidable longitudinally with respect to the screw feed mechanism (6).

Patent CA-2211096-A1 (CA)
Title: High-speed data transmission in mobile communication networks
Inventor: R S NEN JUHA
IPC: H04B7/26
Filed: 1996-03-06
Abstract: The invention relates to a digital mobile communication system and a method for high-speed data transmission in a digital mobile communication system. The mobile network allocates two or more parallel traffic channels to a high-speed data signal which requires a transmission rate that exceeds the maximum transmission rate of one traffic channel. The high-speed data signal is packed into transmission frames which contain a fixed number N of information bits. The number of the information bits is such that the data rate of the frame is fixed and corresponds to a standard rate adaptation of a traffic channel in the mobile comunication system, for example 9.6 Kbps. Among these information bits of the transmission frame, a variable number of bits N1 which is dependent on the data rate of the high-speed data signal is employed for the transmission of the user data. From the remaining "free" information bits of the frame, n bits are control bits which indicate the number N1 of the user data bits in the frame. The remaing k information bits are stuff bits. By means of the invention, the transmission rate of the user data in the transmission frames may vary between 0 and a preset maximum value.
Patent CA-2211696-A1 (CA)
Inventor: PAYE JAMES R
IPC: G06F11/22
Filed: 1996-01-25
Abstract: Un procédé de diagnostic (100) à exclusion de consignation des défauts existant avant le montage empêche la consignation des défauts pendant le montage du système principal tant que le système n'a pas été reconnu opérationnel au moins une fois (116). Ce procédé continue de signaler les défaillances ou les erreurs système détectées (112) en activant une lampe témoin (120), mais il ne consigne pas ces défaillances en mémoire avant que le système ait reconnu au moins une fois que le système principal a subi sans aucune erreur la procédure de mise sous tension (118 et 122). Ainsi, étant donné que ces défaillances ne sont pas stockées en mémoire pendant la fabrication ou le montage, le procédé de la présente invention fait qu'il n'est plus nécessaire d'exécuter d'opération(s) supplémentaire(s) de montage consistant à effacer et/ou réinitialiser la mémoire, ou consistant à fournir au système de diagnostic, des entrées d'enregistrement commandées depuis l'extérieur.

Patent CA-2216039-A1 (CA)
Inventor: DE MARCHI SILVERIO
IPC: G02B6/38
Filed: 1997-09-17
Abstract: A protective flap (5) is arranged on the end of a lever arm formed as a flexible spring on the plug casing (2) of a plug (1, 1'), said protective flap covering the face and the end surfaces of an optical fiber. The lever arm is connected to the plug casing so as to be removable, and is shaped and arranged in such a way that the protective flap is pressed against the face under spring tension when in the closed position. With that, the protective flap assumes not only a screening function to guard against the escape of light, but also practically hermetically closes off the face and thus prevents dirt entering between the protective flap and the face.

Abstract: A  tailoring system and apparatus  for tailoring clothing wherein body  measurements  are  photographically  recorded  for computer data entry from special form fitting articles of clothing to  which disposable  strips  of  tape measures  are  temporarily adhesively affixed.  The customer wears a body suit, an arm band, and a leg band to which disposable strips of measuring tape are temporarily attach around predetermined circumferential portions. The strips of measuring tapes are attached by small pieces of a double sided adhesive tape that do not stick to the body suit, the arm band, or the leg band when the measuring tapes are removed. The customer then stands on an elevated platform in the corner of a specially designed room.  A hand rail is available for balance if necessary.  The room has a camera embedded in the wall facing the customer and another camera embedded in a wall facing one side of the customer.  The walls facing the cameras are imprinted with a grid that is calibrated for parallax to indicate height and width dimensions. The cameras are triggered simultaneously.  Afterward, the customer removes and disposes of the strips of measuring tape. The resulting front view and side view photographs are then either physically or electronically conveyed to an expert at a clothing manufacturing facility who inputs a predetermined set of sizing data to an integrated computer that controls the operation of machinery for the cutting, sewing, and other processes involved in the fabrication of a custom fitted article of clothing for the customer.

Title: Mesure des proprietes mecaniques anisotropes d'un tissu
Inventor: PONOMAREV VIKTOR
IPC: A61B8/00
Filed: 1996-09-27
Abstract: L'invention porte sur un dispositif et un procédé pour mesurer les propriétés mécaniques anisotropes d'un tissu. Le dispositif comprend un résonateur à flexion entraîné par un transducteur (4), lequel est destiné à osciller selon une pluralité d'angles d'oscillation lors d'un contact avec un tissu à analyser. Les fréquences de résonance et les largeurs de crête de résonance du résonateur à flexion sont mesurées à chacune des pluralités des angles d'oscillation. Les propriétés mécaniques anisotropes du tissu sont calculées d'après ces valeurs et la fréquence de résonance à l'état libre du résonateur à flexion en oscillation. Au cours des mesures, un élément de normalisation de pression est utilisé pour garantir un contact sûr et normalisé entre le résonateur à flexion et le tissu. Le procédé permet à un utilisateur de déterminer lesdites propriétés mécaniques anisotropes en mesurant la fréquence de résonance à l'état libre du résonateur à flexion, les fréquences de résonance et les largeurs de crête de résonance du résonateur à une pluralité d'angles d'oscillation lors d'un contact avec un tissu; en calculant les propriétés mécaniques correspondant à chacun des angles d'oscillation, et en affichant ces valeurs de manière utile. Ce procédé peut être mis en oeuvre par un microprocesseur sous la forme de logiciel (30).
