Abstract: An implant assist apparatus is disclosed for implanting material such as a suture in tissue to reapproximate or reinforce the tissue.  A cannula is provided having a hollow body and an open proximal and distal end.  Point means is detachably fixed to the open proximal end of the cannula for penetrating tissue.  A method of implanting the material in tissue for reapproximating or reinforcing the tissue with the implant assist apparatus is also disclosed whereby a length of the implant material is attached to a guide wire for partial containment within the cannula.  The cannula with detachable point is passed into the tissue at an entry point remote from one side of the defect and out an exit point on the opposite side remote from the defect such that the distal end of the hollow body extends from the entry point and a proximal end extends from the exit point.  The detachable point is removed from the cannula and a guide wire with implant material attached is drawn out of the proximal end of the hollow body until the implant material is exposed at both the distal and proximal ends of the hollow body. Thereafter, the cannula is withdrawn from the tissue leaving the implant material in place and the implant material is anchored to reapproximate or reinforce the defect.

Title: Rotary heat exchanger of improved effectiveness
Inventor: PRAVDA MILTON F
IPC: F28D19/00
Filed: 1991-09-27
Granted: 1994-03-29
Abstract: ABSTRACT OF THE DISCLOSURE      A Perkins tube type rotary heat exchanger of improved efficiency wherein the Perkins tube evaporation sections are outwardly  displaced  from  the  condensation  sections  by offsetting and/or  splaying,  to  substantially  occupy  the evaporation sections with Perkins tube working fluid while substantially eliminating the presence of fluid from a major portion of the condensation sections during operation of the heat exchanger.   This has the effect of maximizing the internal evaporative area within the evaporation sections and also of maximizing the internal condensing area within the condensation sections of the Perkins tubes, thereby materially increasing the energy recovery and effectiveness of the heat exchanger.

Abstract: In a device for deterring theft of a protected article, including a pin and clutch respectively embodied in two components that are adapted to be locked together on op-posite sides of a portion of the protected article to prevent unauthorized removal of the device from the article, the pin-containing component contains two fragile elongated glass vials that fracture when at least a predetermined pressure is applied thereto, with the vials containing a detrimental substance that would damage an article attached to the device if such substance were to be released from the vial; and the head of the pin includes a breaker element having a wedge-shaped surface of a fiber-loaded-reinforced thermoplastic, (which does not scratch glass), for applying more than the predeter-mined pressure against the vial In response to the pinhead being moved in response to application to the two components of at least a predetermined threshold separation force, to thereby completely fracture the vials by inducing a high bending stress without prematurely cracking the vials, and to thereby release the substance contained therein before the components are separated by prying or pulling the components apart.  A pli-able seal is disposed between the breaker element and the vials for preventing the detrimental substance that is released from the fractured vials from entering the head space and for expelling the released detrimental substance through the adjacent open-ing in response to pressure applied against the seal by the breaker element by the movement of the pinhead that results in the vials being fractured.

Abstract: On transmet dans le sol des impulsions sismiques réparties dans le temps de façon irrégulière (suivant un code aléatoire ou pseudo-aléatoire par exemple) et on capte par un système de réception les ondes directes et celles renvoyées par les discontinuités du sous-sol. Le spectre de fréquence des signaux émis et reçus est subdivisé en plusieurs bandes et les composantes des signaux dans chacune des bandes sont réduits à des signaux élémentaires traduisant leurs changement de signe (bit de signe) et enregistrées. On procède alors pour chaque capteur du système de réception, à une corrélation des signaux élémentaires associés respectivement aux signaux émis et reçus, à une sommations des produits de corrélation associés à chaque capteur, et l'on réalise avec les sommes obtenues, des coupes sismiques très comparables à ce que l'on obtiendrait en numérisant les signaux reçus en pleine précision, comme dans les méthodes classiques.  Application à la prospection en 2D ou 3D autour d'un puits en cours de forage avec un outil de forage par exemple.

Abstract: An over-the-wire balloon dilatation catheter (20) has a stainless steel hypotube catheter shaft (22), an intermediate sleeve section (24) banded to the shaft (22) and a distal balloon section (25) connected to the sleeve section (24). The sleeve section (24) is formed from relatively flexible polymer materials and includes an inner core tube (80) which defines a guide wire lumen (52) extending only through a distal portion of the catheter (including its sleeve and balloon sections) to facilitate fast balloon catheter exchanges. A distal end (30) of the hypotube shaft is crimped laterally and the core tubs (80) is nested and bonded within the crimp to provide a proximal outlet for the guide wire lumen (52). The hypotube shaft (22) provides an inflation lumen (62) for the balloon, with the inflation lumen (62) being continued as an annular inflation lumen through the sleeve section (24) where an outer sleeve (82) is bonded about the core tube (80) and extends from the distal end of the hypotube shaft to the balloon section. A kink-resistant coil structure (110) extends distally from the distal end (30) of the hypotube shaft (22) to provide a gradual change in stiffness along the length of the catheter (20) from the relatively stiff hypotube shaft (22) to the relatively flexible distal portion of the catheter.

Patent CA-2109173-C (CA)
Inventor: FOX ROBERT EUGENE
IPC: A01B63/00
Filed: 1993-10-25
Granted: 1996-09-24
Abstract: A feedback mechanism for providing an implement position signal includes a rotary potentiometer   mounted  on the implement frame adjacent the rockshaft with the axis of the potentiometer shaft extending parallel to the rockshaft.  A linkage structure includes a potentiometer arm connected to a rockshaft arm by a link such that angle the potentiometer arm forms with the link is acute when  the  implement is in the transport position and obtuse when the implement is in the lowered field-working range.  At the lowermost position of the implement, the link and potentiometer arm approach an overcenter position.  The linkage structure provides amplified rotation of the potentiometer shaft relative to the rockshaft when the implement is in the field-working range of positions, while rotation of the shaft is reduced relative to rockshaft rotation when the implement is raised above the field-working position.  In the preferred embodiment,   rotation of the rockshaft 10° in the field-working range results in rotation of over 30° of the potentiometer shaft.  Rotation of the rockshaft 10° in the upper range of raised transport positions results in less than about 8° of potentiometer shaft rotation. The amplified rotation in the field-working range significantly increases accuracy and repeatability of the feedback signal.

Abstract: In order to considerably reduce expenditures for the dewatering of sludges, particularly from sewage treatment facilities, and thereby perform the step from a sticky, wet solid to a flowable solid granulate practically without the re-admixture of material, it is proposed to employ a solid bowl sludge centrifuge as the dispersing member in a subsequently connected convection dryer for further dewatering of the wet solids particles that are ejected with a dry substance content of approximately 25-35 weight per,cent.  The wet solids particles that are ejected at high speed in the form of a film of particles from the outlet of the solid bowl sludge centrifuge are surrounded by the hot drying gas while still on their trajectory and are pre-dried to a dry substance content of approximately 65 weight percent (Figure 5).
