Abstract: This invention concerns urinary catheterizing and identifies a cavitation occurring at catheter removal as the source of a damaging problem, and shows that a vent to atmosphere of the catheter tip prior to the catheter and vent removal prevents this problem. This invention disclosure shows the vent and method to prevent this problem. The prior art for self-catheterizing specifies six catheterizes and catheter removals per day. Each catheter removal causes a small amount of damage, damage is cumulative and enlarges at subsequent catheterizes. After many catheterizes, the enlarged damage at catheter removal causes a serious bleeding problem. This invention has two cooperative parts related in time as early and later. The early part inserts a lubricated catheter to urethra and bladder to remove urine, and the later part inserts a vent to a catheter urine discharge lumen and catheter tip to prevent this problem at the catheter and vent removal.

Abstract: This invention concerns urinary catheterizing and identifies a cavitation occurring at the moment of catheter removal after catheterizing drainage is completed as the source of a transient damaging problem, and shows that venting to atmosphere of the catheter tip prior to the catheter removal prevents or reduces this transient damaging problem. The venting to atmosphere prevents a transient and partial vacuum formation for a transient cavitation. The invention disclosure shows the vent and method for preventing or reducing this transient cavitation damage. The prior art for self-catheterizing specifies six catheterizings per day. Thus, the prior self-catheterizing art specifies the catheter removals that precede the transient damaging problem. Although each catheter removal causes a small amount of damage, the repeated damage is cumulative and enlarges as subsequent catheter insertions disrupt the healing of previous damage.

Abstract: This invention is for incrementally controlling energizing and de-energizing of at least two electrical motors in which motor armatures are mechanically coupled to a single mechanical member and in which motor stators are mechanically referenced to a second mechanical member. By energizing and deenergizing two or more electric motors of different force and torque capability coupled in this manner it is possible to provide increments of force and torque as small as the incremental capability of the smallest motor and to provide a large number of force and torque increments which can approximate a smooth control of force and torque in forward and reverse directions. The type of motor used for this invention is a multiple-two-node-open-circuit-armature-winding motor as disclosed in the referenced patents. This type of motor offers various levels of energizing the motor to the full force and torque capability.

Abstract: An electronically indicating torque wrench utilizes a variable frequency stress transducer to detect the level of torque applied by the wrench. The stress transducer is operatively coupled to an arm of the wrench, said arm having a mechanical stress that is a function of an applied torquing force. The output of the stress transducer is compared to a reference whose calibration corresponds to desired torque settings. An indicator provides audible and visual indications when the applied torque equals the desired value.
