Abstract: A grilling appliance includes a housing defining an internal grilling compartment for receiving food articles to be grilled; an impaling member mounted within the grilling compartment for impaling a food article to be grilled; a circular array of electrical heaters surrounding and spaced from the impaling member for heating a food article when impaled thereon; and an electrical system for sequentially energizing the electrical heaters to produce a rotating heating front which rotates around a food article when impaled on the impaling member. Each electrical heater is shaped in the form of a loop extending for a part of the circumference of the grilling compartment and has a pair of mounting legs at one end joined by a U-section at the opposite end.

Abstract: A method and apparatus for sputter-depositing a layer of a material on a substrate, in which the layer is applied to the substrate by sequentially effecting a plurality of partial sputter-deposits thereon during a plurality of operational periods each including a sputter-deposit time interval followed by a non-deposit time interval of at least equal duration to the sputter-deposit time interval.

Abstract: A firearm including a frame having a grip for manually grasping the firearm, a control member movable to enable firing the firearm, a locking device including a latch element movable by an inserted key either to a locking position or to a releasing position, and a locking member movably carried by the frame. A spring urges the locking member into contact with the control member such that the locking member moves with the control member to enable firing the firearm. The locking member is located with respect to the latch element of the locking device so as to be engaged thereby when the latch element is in its locking position, to block the movement of the locking member, and thereby to prevent the firing of the firearm when the latch element is in its locking position. Two embodiments are described: a semi-automatic pistol, wherein the control member is a pivotal safety lever; and a revolver, wherein the control member is a rebound slide.

Abstract: A massaging appliance for dispensing a massaging cream includes a cream dispenser unit attachable to the appliance housing and coupled to a rotary motor therein to be rotated thereby, and a non-rotatable rod within the appliance housing axially displaceable towards and away from the dispenser housing for engagement with a piston stem in the dispenser housing to block its rotation, and thereby to cause a piston, within the dispenser housing and while rotating therewith, to move axially towards an end wall in the dispenser housing and to force cream through dispenser openings therein.

Abstract: A method of assessing the cardiovascular performance of a subject, by: applying periodically, in synchronism with every n.sup.th heart cardiac cycle wherein "n" is at least two, external pressure pulsations on a peripheral organ of the subject sufficient to alter ventricular loading; acquiring data representative of the ventricular pressure, and data representative of the ventricular volume, of the subject's heart over a plurality of heart cardiac cycles; and utilizing such data for assessing the cardiovascular performance of the subject. Ventricular loading may be altered by impeding ventricular ejection (changing afterload), and/or by altering venous return to the heart (changing preload).

Abstract: A testing bed for use in testing printed circuit boards and the like includes a light-transmissive supporting member, a plurality of spaced strips of light-transmissive, electrically-conductive material on one face of the supporting member, and a plurality of probe elements overlying and in contact with the strips. Each of the probe elements includes an outer electrically-conductive contact point for contact with a pad of the article to be tested. A photoconductive material between the probe elements and the strip forms a photoconductive gate.

Abstract: The tether cord is secured to the ball by a stud having an enlarged head engaging the external surface of the ball, and a shank passing through an opening in the ball and formed with a shoulder engaging the inner surface of the ball. The underface of the enlarged head is formed with a cavity for receiving one end of the tether cord, and with a bore extending from the cavity to the outer surface of the enlarged head through which the tether cord passes. The cavity is eccentric with respect to the enlarged head, and the outer end of the bore is centric with respect to the enlarged head.
