Title: Child resistant hinge top closure
Inventor: SMALLEY NED J
IPC: B65D47/08

Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE      A hinged dispensing closure of unitary molded construction is disclosed which may be readily opened by an adult using one hand.  A narrow slot of short length is molded near the periphery of the top wall of the snap-hinged cover cap opposite its hinged connection to the main closure.  The sidewall of the cover cap includes axially extending parallel score lines from near its skirt edge to the ends of the slot to define a tab.  Pressing by the thumb on the tab while holding the package in the same hand ruptures the scores and deflects the tab inwardly for ready access to an exposed edge of the formed slot; and pressure on the edge opens the cover cap.  The deflected tab is held by an internal cam wall inwardly of the slot, which indicates that the package is opened when the tab is held in this deflected position.  A second embodiment provides a hook and latch locking means between the main closure and cover cap opposite the hinge.  This lock may be disengaged by the thumb for unlatching the cover cap by depressing its skirt wall at the hook and latch location and opening the cover cap with one hand.  The main closure is threaded on the container.  The main closure and container are provided with cooperating ratchet teeth to render the closure on the container a safety closure against accidental removal by children.

Granted: 1994-03-01
Abstract: NONINVASIVE CONTINUOUS MEAN ARTERIAL BLOOD PRESSURE MONITOR              Abstract of the Disclosure An apparatus and a method use noninvasive electrical bioimpedance measurements to monitor the means arterial blood pressure of a patient on a continuous (heartbeat-by-heartbeat) basis.  The apparatus and method process the electrical impedance across two segments of body tissue to provide  a  signal  for  each  segment  that  indicates  the increase in blood flow in each segment at the beginning of each cardiac cycle.  The apparatus and method process the signals corresponding to each segment to measure the arterial pulse propagation delay between the two segments. The arterial pulse propagation delay is inversely related to the mean arterial blood pressure of the patient.  The apparatus and method use the measured arterial pulse propagation delay to calculate the means arterial blood pressure of the patient.  The cardiac output of the patient is also advantageously measured and the cardiac index of the patient calculated from the cardiac output.  The cardiac index and the mean arterial blood pressure are then used by the apparatus and method to calculate the left cardiac work index and the systemic vascular resistance index of the patient.

Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE:           A circuit for measuring the effective voltage drop at the welding position between the welding electrodes of a resistance seam welding machine.  A first measuring loop for measuring a first  loop voltage is secured to the lower welding arm close to the lower welding electrode and is in communication with the upper welding electrode through a sliding contact.  The second measuring loop is taken close to the welding electrodes through the head portion of the Z-rail.  The conductor turns of both measuring loops,  which lead to an evaluation circuit are twisted together.   Thus the stray effects picked up in the two measuring loops are the same.  The difference between the two loop voltages formed in the evaluation circuit is the effective voltage drop which is further processed in the usual manner to monitor the quality of the welding seam produced.
