Abstract: ABSTRACT OF THE DISCLOSURE        An inertia-dependant switching device in which a roller element, preferably a ball, is accommodated in a concave seat for radial movement into contact with a switch member such as an electrical contact or a plunger.  The seat has an inner portion in which the ball is mounted when the switch is subject to a steady force acting along a first axis extending through the centres of the ball and the inner portion of the seat, and has an outer portion on to which the ball is able to roll as a result of a predetermined change in the force acting on the ball.  The inclination to the first axis of the surface of the outer portion is greater than the inclination of the surface of the inner portion and both portions are preferably formed as surfaces of revolution, such as frustra of cones having different opex angles, which meet at a circular edge. When the force urging the ball to roll radially from its rest position increases sufficiently to cause the ball to roll over the edge between the inner and outer portions of the seat, continued rolling movement is in a direction more closely aligned with the force and so the ball moves more rapidly into contact with the switch member.  Where the switch member is a plunger, it may be used to release stored energy in a trigger mechanism for operation of a device requiring greater input energy than the energy supplied to the plunger by the seismic ball.

Abstract: ABSTRACT   A high intensity light source having high repetition rate and narrow pulse-width.  The light source comprises a metal casing having first, second and third coaxially mounted arcing electrodes therein forming dual series-connected arc gaps, which utilize the capacitance of the coaxial system to charge up to the arcing potential.  The first electrode is electrically connected to the end wall of the casing to provide a reflected wavefront from the end wall after an arc has been struck across the gap between the first and second electrodes, such wavefront serving to extinguish the arc and thus provide a sharp pulse.  The second and third electrodes are both capacitively coupled to the casing and the third electrode forms in conjunction with the second electrode a gap having a higher breakdown potential than the gap between the first and second electrodes. The lamp may be used for such areas as photochemical and photobiological research, in place of much costlier nanosecond lasers.

Abstract: A PULSE WIDTH MODULATED VOLTAGE REGULATOR-CONVERTER/POWER CONVERTER HAVING PUSH-PUSH                REGULATOR-CONVERTER MEANS          ABSTRACT OF THE DISCLOSURE:         Disclosed herein is an improved pulse width modulated (PWM) voltage regulator-converter system which can function, alone, as a switched voltage regulator system or in combination with a switched power converter, synchronized therewith, to form an improved voltage regulator-converter/ power converter system.  In the pulse width modulated voltage regulator-converter embodiment of the invention, secondary windings of a "current mode" regulator-converter interstage transformer are coupled to regulator-converter power transistors in a push-push circuit configuration.  The primary windings of the regulator-converter interstage transformer are driven by a pulse width modulated logic control means connected thereto in a push-pull circuit con-figuration.  Signals generated by a system clock means and an error signal, derived from the output of an averaging filter, drive the pulse width modulated control means such that logic signals generated at its output, at the primary windings of the regulator-converter interstage transformer, connected thereto, balances the magnetic operating point thereof and drive the regulator-converter power transistors, thereby increasing the maximum regulated output voltage of the voltage regulator-converter system after conditioning in an averaging filter.

Abstract: HOSPITAL BED SECURITY COVER     Abstract of the Disclosure The application discloses a rigid or semi-rigid, two-part confining cover for a patient in a conventional hospital bed.  The problem dealt with is that of a distrubed patient who would normally require confinement by ties, straps, or other conventional restraints, together with, in many cases, round-the-clock guarding by an attendant.  The mattress support frame of a hospital bed usually has one or more horizontal pivot joints, the most important of which enables tilt-up of the back of the bed.  Knee lift provisions are generally provided.  The disclosed cover includes for-ward and rearward open-bottom shells, hinged to one another about the hinge axis of the bed used for tilt-up of the back part of the bed.  The front shell has side walls rising from the longitudinal edges of the bed frame, forward of the aforementioned pivot axis, a front end closure, and a top closure.  The back shell has side walls rising from the longi-tudinal edges of the bed frame from this pivot axis back, a rear end wall, and a top wall.  The rear end of the front shell and the forward end of the rearward shell are fitted together in a manner to form a closure throughout the range of tilting of the rearward shell.  The shells are perforated for air circulation, and are commodious enough to permit the patient adequate space for relatively free movement inside the closure.  Access doors are provided.

Abstract: Abstract of the Disclosure A training device for competitive swimmers in the form of a drag suit adapted to be worn over the swimmer's regular suit.  The drag suit adds weight and increases the resistance (drag) to the swimmer's movement through the water and thus helps in the development of the swimming muscles.  The increased drag is caused by a plurality of pockets on the front and back of the suit which pockets open in the direction of the swimmer's movement through the water.  Water entering the pockets is impeded in flowing through them whereby the drag is created.  The pockets are located on the suit in such a manner that the drag is distributed evenly on the swimmer with no imbalance tending to cause the swimmer to roll or dip.

Abstract: A coin slide apparatus which includes a housing for mounting the apparatus to a machine, a coin slide assembly, and a guideway in the housing for the coin slide assembly to operate within.  The coin slide assembly is reciprocally operable in the guideway from at extended coin receiving position through coin measuring and coin ejection positions to a position for initiating operation of the machine.  The movable slide assembly comprises two main members:  an upper slide plate and a center slide plate.  The upper slide plate is formed to include the operating handle at one end and has coin receiving slots of a predetermined size.  The center slide plate has downwardly projecting fingerlike members defining between them coin pockets subjacent the slots in the upper slide plate for supporting coins on edge and further defining coin pushers.  The center slide plate also serves as a storage area for blanking members which axe used to convert the apparatus from one combination of coins to another.  Coin sensing levers are pivotally mounted alongside gaging blocks and extend upward to engage with tracks in the center slide plate.  The coin sensing levers are biased toward the coin measuring area.  Proper coins are vertically supported on the gaging blocks with the upper edge of the coin face engaging a shoulder portion of the coin pockets in the center slide plate.  Improper coins are not supported between the gaging blocks and the shoulders but are pivoted sideways by the coin sensing levers which then cooperate with stops in the tracks of the center slide plate to prevent operation of the coin slide assembly.
