Patent CA-2098119-C (CA)
Title: Tissu pouvant servir de doublure de coffrage pour betonnage
Inventor: SERAFINI FRANCO LUIGI
IPC: B28B7/36
Filed: 1991-12-10
Granted: 1997-12-02
Abstract: Coffrage à béton équipé d'un revêtement à coffrage fabriqué d'un tissu dont l'étendue de la taille des pores de chacun des côtés opposés est différente. Dans une version, un revêtement microporeux, telle qu'une dispersion de micromousse de chlorure d'éthylènevinyle, est appliqué sur un côté d'un tissu perméable (13) afin de réduire de façon contrôlable la taille des pores de ce côté, pour qu'elle se situe entre 0,2 et 20 microns. Le tissu enrobé est utilisé avec un support (11) et une grille (12) de manière à composer un système de coffrage à béton (10) selon lequel le côté enrobé du tissu (13) entre directement en contact avec le béton. Le revêtement microporeux stabilise les fibres de surface du tissu (13), ce qui réduit la tendance du tissu à coller au béton. La taille des pores du côté enrobé du tissu doit être suffisamment petite pour empêcher essentiellement toutes les particules de béton de passer à travers le tissu, mais suffisamment grande pour laisser passer l'air et l'eau.

Abstract: Une poudre de matière brute pour supraconducteur d'oxyde de bismuth est moulé avec addition d'un véhicule organique; la matière brute moulée est traitée thermiquement pour l'élimination du véhicule organique avant le revêtement de la matière brute moulée par un métal. Dans ce traitement thermique, seules les conditions déterminées par l'équation T = -71.5 x log H + 600 s'appliquent quant à la relation entre la température T (en °C) et le temps (en heures). Ainsi la transformation de 2212 phases, constituant en grande partie la matière brute, est supprimée, ce qui entraîne la formation d'une importante quantité de 2223 phases possédant une température critique relativement élevée lors du traitement thermique après le revêtement métallique.

Abstract: A transmitter (10) is provided with a distribution preserving Tomlinson coder (25) which predistorts shaped data signals (20) such that the power of each data signal exiting the coder is substantially similar to the power of the data signal entering the coder and such that upon transmission of the predistorted data signal over a channel (40), the effect of ISI of the channel is substantially removed. The transmitter is primarily intended for coded modulation systems utilizing a "coset" code, and the predistortion is preferably accomplished according to a linear function (1), where r k is a data signal entering the coder, a1 and b1 are the coefficients of polynomials relating to the channel impulse response, x k is the predistorted data signal exiting the coder, and s k is chosen to cause the signal power of x k on average to approximately equal the signal power of r k on average. Different methods for so choosing s k are disclosed. Receivers (50) which cooperate with the provided transmitters (10) are also provided.

Title: Catheter tube and method of manufacturing the tube
Inventor: OKAJIMA NAOFUMI
IPC: A61M25/00
Filed: 1993-10-22
Granted: 1997-09-09
Abstract: A catheter tube is composed of a main portion 22 and a tip portion 23.  The main portion 22 of the catheter tube is of such a structure that an inner tube 4 and an outer tube 6 are joined via a reinforcing material layer 5, but the tip portion 23 is of such a structure that only the inner tube 4 and the outer tube 6 are joined without intervening the reinforcing material layer 5 between the two tubes.  The reinforcing material layer 5 is formed by arranging a filamentous element (e.g., stainless steel wire) 51 around the inner tube in a lattice manner.  The inclination angles .theta.1, .theta.2 and .theta.3 of the filamentous element 51 with respect to the axis of the catheter tube at the first, second and third regions 221, 222 and 223, respectively are determined so as to establish the relationship as .theta.1 > .theta.2 > .theta.3.  Therefore, the rigidity of the catheter 2 can be increased in accordance with the decrease of the inclination angle of the filamentous element 51.  According to the catheter tube, excellent pushing, torque transmission, follow-up to a guide wire, and kink-resistant characteristics can be attained, simultaneously and respectively.

Abstract: The recovery of each signal in a transmitted signal including a pair of superimposed signals is improved by the use of linear prediction. The pair of signals includes various combinations of analog and digital signals, e.g., an analog signal sample superimposed upon a digital signal sample, or a digital signal sample superimposed upon another digital signal sample. In a first embodiment, prediction coefficients for the analog signal are generated from the received signal. These coefficients are then used to recover the analog and digital signals from the received signal. In a second embodiment, the analog signal recovered, pursuant to the first embodiment, is considered a tentative estimate of the analog signal, and prediction coefficients for this tentative analog signal estimate are formed and used to generate final estimates of the analog and digital signals. In still other disclosed embodiments, prediction coefficients are transmitted to the reciver, and the analog signal superimposed  upon the digital signal is a residual analog signal for which prediction coefficients are generated without regard to the transmitted prediction coefficients. These prediction coefficients are then used to recover the digital signal and the residual analog signal. The residual analog signal is then processed using the transmitted prediction coefficients to recover the analog signal. Further embodiments disclose several techniques for generating prediction coefficients for the analog signal.

Abstract: A device for exhibiting flat articles consists of a profiled frame (3), which surrounds a picture (1) on all sides round its outside (24). A flange (7) is formed on an inwardly directed web (29) of the profiled frame (3) which is in register with a further web (9) running parallel to the rear side (32) of the picture frame (2), the flange facing towards the viewer and having a sheet of glass (10) fixed to its end, the glass closing the profiled frame (3) on the side facing the viewer. The picture (1) is pressed against the side of the web (29) facing away from the viewer by elastic pads (16), which bear against a rear wall (12) connected to the rear side of the profiled frame (3). The edge (33) and the marginal region of the sheet of glass (10) are received by a rectangular recess (21) of the picture frame (6). Since the inwardly directed web (29) is in register with the outwardly directed further web (9), the face side of the picture (1) is located in a plane behind the rear side (32) of the picture frame (2). The device according to the invention can protect a picture (1) from damage and also against environmental effects given an air-tight implementation of the frame receiving the picture, while the overall impression of the picture (1) and the picture frame (2) stays virtually unchanged and reworking of the picture frame (2) to receive the profiled frame (3) is dispensed with.

Abstract: The application discloses a device (10) to retrofit into the cabinet (11) of newspaper vending machine racks to prevent the removal of more than one copy of the newspaper for each vend or door opening of the cabinet (11).          The single vend device (10) consists of a front panel (12) with a T-slot (14).  The arms (14a) of the T-slot (14) are normally closed off with a pivoted closure plate (16).  Con-sumer access to the newspapers is provided through the leg of the T-slot (14b), but the newspaper must be slid through the gap between the closure plate (16) and the front panel (12).  The thickness of the gap is adjustable to selectively allow for the variation in thickness between various edi-tions of the newspaper.  The closure plate (16) is spring loaded to be biased to the closed position.  Following removal of the paper, the closure of the plate (16) and a locking pin (32) prevents the plate (16) from re-opening.          The locking pin (32) is disarmed upon closure of the cabinet (11) door (25a).
