Abstract: A connecting structure in which a male connector can be fitted into a female connector by operating a joint lever is provided. The joint lever is rotatably attached to either the male connector or the female connector. The connecting structure further includes projections to be inserted into the guide grooves and a fit detecting member for detecting the fitting condition between the male connector and the female connector. In fitting the male connector into the female connector, the fit detecting member is released from its engaged condition in the temporary engagement position by rotation of the joint lever. In the case where the fit detecting member is engaged in the formal engagement position, the fit detecting member operates to prevent the joint lever from being rotated.

Abstract: In a non-commutating-pole commutator motor, in particular as the drive of a power hand tool, a device for reversing the direction of rotation includes a switch (8) for reversing the direction of current in the rotor winding, and a brush apparatus (4) mounted immovably in the motor casing. The rotation of the plane defined by the commutating coils is chosen in such a manner that good commutation is assured in one of the two directions of rotation at full motor output. Furthermore, the switch (8) for reversing the direction of rotation yields the preferred direction of rotation in a first switch position and the opposite direction in a second switch position. In the switch position for the preferred direction, a smaller number of turns of the field winding (1, 2) in the electric circuit of the motor is effectively provided while, in the opposite direction of rotation of the motor, a larger number of turns is effectively provided.

A lower plate portion of the joint part extends from the base plate portion till the engagement portion and has a width larger than that of the base plate portion. The upper plate portion extends from the free marginal portion till the engagement portion and has a width larger than that of the free marginal portion. Owing the structure, the strength of the joint part can be maintained.

Abstract: Apparatus and methods are provided for relieving a stenosed region of a blood vessel such as a coronary using a single catheter that relieves the angioplasty by conventional means and then delivers an easily controllable inherently uniform dosage of radiation to the walls of a blood vessel for preventing restenosis after angioplasty. An embodiment of the apparatus comprises a catheter having an angioplasty balloon that is inflatable with a liquid containing a suspended radioactive material such as .sup.125 I or .sup.32 P. The balloon is surrounded by a membrane to capture the radioactive liquid in the event the balloon ruptures. The catheter is advanced through the patient until the balloon is disposed in the stenosed region of the blood vessel.

Abstract: A method of and a meter box apparatus for connecting a electrical service lateral to a misaligned meter box mounted on the exterior of a building structure such as a residence are disclosed. The meter box apparatus comprises a rectangular box-like enclosure with a removable bottom panel having a knock-out which can be placed over the misaligned service lateral and affixed to a conduit carrying the service lateral. The bottom panel is then urged into position in the meter box by flexing the conduit and is fastened in place to provide a neat, professional-looking connection.

Abstract: An elongated, substantially rigid member suitable for use as a marine piling is formed by feeding a substantially solid plastic core into a die and continuously extruding a molten plastic into the die so that the molten plastic surrounds and bonds to the plastic core and to reinforcing bars fed into the die at positions surrounding the plastic core. The plastic core acts as a heat sink to facilitate cooling of the molten plastic and deters bending of the member while cooling.

Abstract: A system and a method for counting the number of people passing a entry point in a predetermined direction. The system includes a foot-activated, pressure sensitive platform deployed at the entry point for providing a time-dependent pressure profile vector indicative of the manner in which a person arches one of his feet prior to at least partially stepping off the platform. The pressure profile vector is processed for determining whether the person completely passed through the entry point in the predetermined direction. In the affirmative case, a counter for recording the number of people completely passing through the entry point in the predetermined direction is incremented. The system can be adapted for providing a net count of the instantaneous number of people in a given area during the entering and leaving of people through an entry point into and from the given area.

Abstract: Atrial fibrillation disorders are treated by locating low impedance electrodes positioned on a single catheter body passing through the pulmonary artery valve to locate the electrodes respectively in the right atrium and the pulmonary artery. Thus an electrical energy impulse of the order of three joules is passed through a heart and tissue path establishing a field gradient for resetting atrially fibrillating cells to convert atrial fibrillation into sinus rhythm. A special non-implantable catheter for temporary use provided for this treatment method is characterized by an inflatable balloon on the distal tip end, two low impedance energy discharging electrodes spaced to reside respectively in the right atrium and the pulmonary artery and a flexible polymer catheter body sheath of a diameter of the order of two millimeters.
