Abstract: A heated catheter for monitoring cardiac output. Displaced from a distal end of a heated catheter (30) is a resistive heater (32) that heats blood flowing within a heart muscle (10). The resistive heater is mounted on the catheter so that when the catheter is inserted into the heart, the resistive heater is disposed in the right ventricle. A temperature sensor (34) is disposed downstream of the resistive heater, in or proximate the pulmonary artery during use. A  differential amplifier (40, 70) provides an electrical current to the resistive heater that varies as a function of the difference between the temperature of the resistive heater, measured by a temperature sensor (35), and a predetermined temperature. In another embodiment of the invention, a resistive heater (90) has a resistance that varies with temperature. The resistive heater comprises one arm of a bridge circuit (85). A differential ampli-fier (110) provides an electrical current to the bridge circuit in response to the voltage developed across the bridge circuit.

Abstract: A guiding system for large circular saws wherein the guiding pads are positioned according to a typical angular wavelength of a circumferential vibration wave of the saw blade when rotating at an operating speed. In one embodiment, the frequency of a natural circumferential vibration wave is measured before positioning the guiding pads. Two sets of guiding pads are spaced apart a distance equal to about half the angular wavelength of such natural vibration wave. This distance corresponds to an angular distance between two successive opposite peaks or crests of a sinusoidal wave in the saw blade. The consequence of two successive opposite peaks entering the guiding pads at the same time has the effect of dampening the vibration very quickly, by acting upon both sides of the saw blade simultaneously, to reduce the amplitude of the wave, while maintaining balanced axial impact on the saw. The guiding pads are further positioned in a true co-planar relationship with the saw blade by means of two superimposed three-point levellers, on the pad supporting members.

Abstract: The ball end (16) of the piston rod (14) of a linear motor (6) is mounted in a ball block (52).  The block (52) has mating housing portions (54, 56) that abut along mating surfaces (64) that are substantially parallel to, but slope relative to, the motor axis (X).  One housing portion includes an integral rear wall (70) through which the axis (X) extends and which defines a portion of a socket (58) that receives the ball end (16). The other housing portion has a flange (78) that projects into a space between the socket (58) and a sloping extension (74) of the wall (70).  The outer surface (76) of the wall (70) is secured to a fixed support (84).  The wall (70) transmits loads carried by operation of the motor (6) from the ball end (16) directly to the  support  (84)  and minimizes  loads  on the fasteners (68) securing the housing portions (54, 56) together. The housing portion that includes the wall (70) is made from a material with a high load carrying capability.  The other portion 16 relatively easy to machine and includes a passageway to deliver fluid to the ball end (16).  A reinforcing bar (150) extends rearwardly from the motor (6) through a channel formed by a floor member of a reciprocating floor conveyor.

Dans un chariot élévateur (10) actionné par batterie, doté d'un mât (20) et d'un chariot (24) à fourches (27), un opérateur se tient debout latéralement par rapport à la direction de déplacement. Le déplacement du levier de commande (34) de la droite vers la gauche à partir d'une position neutre par rapport à la direction faisant face à l'opérateur permet de commander la direction avant et arrière et la vitesse du chariot. Le fonctionnement du mât (20) et du chariot (24) est commandé par le levier (34) poussé ou tiré transversalement à la direction de déplacement. La force nécessaire pour déplacer le levier (34) dans une direction est inférieure à celle nécessaire pour déplacer le levier dans l'autre direction, ce qui correspond aux capacités des différents groupes musculaires utilisés. Le mouvement du levier (34) correspond donc à la direction de mouvement de la fonction particulière à effectuer.

Abstract: Tube mounted bracket structure for a toolbar or similar tube with a rectangular cross section includes a bracket having a tube abutting flange with an aperture offset from an elongated slot.  A rotatable insert has an inwardly directed and elongated projection conforming to the shape of the elongated slot and an aperture located at one extremity of the projection.  The aperture extends through the projection and through an integral washer portion which defines an enlarged shoulder area for contacting the tube abutting flange when the insert is positioned in the slot.  The elongated projection generally fills the entire slot with the exception of the aperture, thereby presenting a relatively solid bolt receiving area for mounting a U-bolt or similar bolt structure.  For a toolbar or tube having relatively large cross section, the insert is positioned in the slot to provide maximum offset from the flange aperture.  If the bracket is attached to a toolbar or tube with smaller cross section, the insert is rotated 180 degrees from the position for the first cross section so the projection aperture is positioned to provide minimum offset from the flange aperture.
