Abstract: ABSTRACT        An electronic control system for a carburetor of an internal combustion engine for controlling the air-fuel ratio to a value providing satisfactory cold engine operating performance.          The system comprises an automatic choke device having a heater operative in response to the temperature of the device to close the choke valve, an oxygen sensor for detecting the content of the exhaust gases, an air-fuel ratio controlling means, and an electronic control means selectively operative to the signals from the oxygen sensor and the automatic choke device.  The heater of the automatic choke device is a PTC heater, the resistance of which increases with the increase of the temperature thereof,  The air-fuel ratio control means comprises an electro-magnetic valve for controlling the fuel supply or air flow rate.  When the oxygen sensor does not operate in the cold, the electronic control means is operated in accordance with the signal from the automatic choke device to actuate the air-fuel ratio control means for correcting the air-fuel ratio provided by the automatic choke device according to the current flowing the heater to a value providing satisfactory operating performance.

The system pressure and the rate of pressure increase as a func-tion of incremental change in volume, or mass, are monitored. decrease in the rate is indicative of the onset of plastic expansion of the sleeve or tube, as the case may be.  By determining this point, the outer diameter of the tube may be accurately controlled to within six thousandths of an inch.

Abstract: BALLOON CATHETER                         ABSTRACT    A balloon catheter for insertion in a body passage includes an elongated coil spring which defines a lumen. This coil spring is covered by a silicone covering which includes an extensible sheath, a strain relief collar affixed to the sheath, and a balloon tip affixed to the strain relief collar.  The extensible sheath and a portion of the elongated coil spring form in combina-tion a support structure which perceptibly elongates when an excessive stretching force is applied to the support structure in pulling the balloon through a body passage.  As this support structure elongates, the volume of the lumen of the coil spring increases. Preferably the balloon is in fluid communication with the lumen of the coil spring such that the volume of -the balloon is reduced when the support structure elongates.  The strain relief collar is adapted to extend away from the spring to receive fluid from the balloon to reduce fluid pressure within the balloon when fluid pressure within the balloon exceeds a pre-determined value.  One preferred embodiment includes a flexible disc-shaped chamber in fluid communication with the balloon, which chamber is sized to fit between the thumb and opposing finger of a user.

Abstract: ABSTRACT OF THE DISCLOSURE         A fluid bearing with a multicomponent membrane which is inflated to form a torus defining a plenum chamber.  The preferred three layer membrane has a fluid impermeable inner layer, a middle layer of a dimensionally stable fabric, and an abrasion resistant outer layer.

A number of different mechanisms for attaching the layers to the load-carrying member of the bearing are shown, and different membranes having different lift heights may be used with a single load-carrying member.  In one embodiment one of a series of interchangeable metal rings of different diameters used with the middle layer of the membrane may be selected to control the lift height.  The bearing also includes a replaceable orifice plate which controls the rate of flow into the plenum chamber and into and out of the torus membrane.

At a position spaced upstream from the turbulizer the wall of the feet tube is pierced with a plurality of holes equally spaced throughout its periphery.  The holes provide centering jets which oppose vibration of the feed tube and prevent impacting of the same against the interior of the lance tube.
