Title: Liquid spray machine for coating interior of pipes
Inventor: HART MILBURN L
IPC: B05B13/06
Filed: 1992-07-15
Abstract: The invention is a spray machine for spraying liquid coating material onto the interior surface of a pipeline. The spray machine is provided with a movable frame which can be rolled on attached wheel assemblies through the pipeline and positioned with its spray gun pointing toward the interior pipe surface. The frame serves as a base to which the other parts of the spray machine attach. The spray gun and an attached hollow gun rotating shaft continuously rotate axially within the pipeline. When the spray gun is properly positioned, the spray gun is mechanically turned on and off by a cable attached to a gun actuating arm which is pivotally mounted on a bracket attached to the gun rotating shaft.      The gun actuating arm is provided with a cam follower which travels in a rotating path against a movable cam plate assembly. The cam plate assembly is attached to and moved rearward by pistons of air actuated cylinders. When the cam plate assembly moves rearward, it pushes against the cam follower, causing the gun actuating arm to pivot and exert tension on the cable, turning the spray gun on.      When air is released from the air cylinders, tension is released on the cable, turning the spray gun off. Liquid coating material is supplied to the spray gun via a rotary fluid coupling. The rotary fluid coupling allows liquid coating material to flow through the coupling while one half of the coupling remains stationary with relationship to the frame and the other half rotates with the spray gun and the gun rotating shaft.

Title: Mode switching pacemaker
Inventor: DUFFIN EDWIN G
IPC: A61N1/365
Filed: 1991-11-13
Abstract: A mode switching bradycardia pacemaker especially adapted for incorporation in an antitachyarrhythmia pacing and/or cardioversion/defibrillation system, provides AAI pacing in the absence of an intrinsic atrial rate exceeding the pacing lower rate and as long as the patient's heart is capable of normal AV conduction. The pacemaker switches to VVI mode any time that the patient's ventricular rate falls below a predetermined value. The mode switching may be implemented in a DDD pacing system or in a pacing system employing an atrial and ventricular sense amplifier and a single pacing output circuit and switching circuitry for switching its output between atrial and ventricular leads. This bimodal operation allows use of AAI pacing for the antiarrhythmic and hemodynamic benefits of maintaining atrial function in patients with sinus node disease, but obviates the risk of ventricular asystole should the AAI mode become ineffective due to transient or newly evolving permanent impairment of AV conduction in those patients where atrial synchronous tracking is considered undesirable.
