Title: Circuit interrupting device with arcing rod speed modifying means
Inventor: BILLER BRUCE A
IPC: H01H85/38

Granted: 1981-12-22
Abstract: CIRCUIT INTERRUPTING DEVICE WITH ARCING ROD SPEED MODIFYING MEANS ABSTRACT:  A lead weight or other mass is crimped to the contact button assembly of the arcing rod of a high-voltage alternating current power fuse thereby increasing the mass of the acring rod without increasing the diameter of the rod.  The increased mass of the arcing rod decreases the velocity with which the arcing rod moves upon fusing of the fusible member thereby decreasing the rate of elongation of the arc drawn between the end of the arcing rod and the stationary ferrule at the other end of the fuse.  Under high current conditions, the shorter arc length drawn in the fuse reduces the pressure of the arc extinguishing gas generated by the arc, thereby reducing the risk that an economically constructed fuse will burst in those situations when the arc is not interrupted at the first current zero.  This result is accomplished without adversely affecting operation of the fuse and interruption of the arc at low current levels.

Abstract: ABSTRACT Process for preparing a high density bread having a relatively strong cell structure which is suitable for making bread crumbs or cubes for use in stuffing mix which comprises preparing a fully developed yeast containing bread dough with an initial mixing to full development, and resting said developed dough. Thereafter dividing, and then baking said dough, during baking the dough being initially subjected to a temperature sufficiently high and for a period of time effective to kill the yeast and prevent substantial oven spring and then continuing baking until the bread dough is fully baked. This process is carried out either without a proofing step or with a minimal proofing step prior to the baking of the dough, the proofing and oven spring being limited so that the density of the resultant baked bread is within the range of about 17 to 36 lbs./cubic ft. The bread is then staled and divided into crumbs or cubes for incorporation into a stuffing mix. The bread crumbs or cubes obtained according to this process have structural strength, an excellent taste, and a density of from about 12 to 22 lbs./cubic ft. The crumbs also hydrate without the formation of a pasty mass and generally retain their individual identity in a stuffing.

Abstract: ABSTRACT OF THE DISCLOSURE         Method of and apparatus for automatic defibrillation of the cardiac ventricles of a heart wherein both the mechanical and electrical activities of the ventricles are sensed and used as operating inputs to the controls.  Electrical activity is detected and measured with a pair of electrodes, and the waves of an electro-cardiogram (ECG) are analyzed.  When such electrical analysis indicates that ventricular fibrillation is present and persists, an electrical circuit is actuated for detecting mechanical pumping activity of the heart.  Mechanical pumping activity is measured by the change in impedance between the pair of electrodes in one of the ventricles. The change of ventricular impedance is caused by the varying volume of blood contained within the ventricle and depends upon whether the ventricle is in a contracted or a relaxed state.  The defibrillator is actuated only when both the mechanical and electrical activity of the ventricle indicates a need for defibrillation.  Because some conditions may be encountered which closely resemble ventricular fibrillation, the defibrillator quantitatively proprograms and weighs the relative importance of the electrical and mechanical signals from the heart.
