Abstract: HIGH FREQUENCY POWER SUPPLY USING A NON-SATURATING MAGNETIC AMPLIFIER CONTROLLER                 ABSTRACT OF THE DISCLOSURE    A DC to DC converter (50,  60,  70) that includes a switching circuit (10) responsive to a DC input, a magnetic amplifier  controller  (20)  responsive  to  the  switching circuit for providing an AC output, and an AC current to DC voltage rectifying circuit (30) responsive to the output of the magnetic amplifier controller for providing a DC output voltage.   The magnetic amplifier controller includes a variable inductance (L1) that cooperates with the switching circuit to form a resonant DC to AC inverter (110) that provides to the magnetic amplifier controller a current whose amplitude is controlled by the variable inductance. The magnetic amplifier controller provides an approximately sinusoidal  output current which  is  a  function  of  the current input thereto, and the DC voltage output of the AC current to DC voltage rectifier is a proportional to the input current provided by the magnetic amplifier control-ler.  Thus, the DC voltage output of the DC to DC converter is  controlled by the  control  current to the magnetic amplifier controller.

Title: Child resistant closure with easy opening feature
Inventor: REIFERS RICHARD F
IPC: B65D51/12
Filed: 1994-01-24
Abstract: ABSTRACT     There is provided a snap-on closure adapted for use with a container available as a child resistant package wherein a closure skirt is provided with at least one break or disruption permitting the skirt to resiliently flex radially outwardly beyond the limits of its inherent hoop strength as snap beads ride upwardly over the major diameter portion of the locking rib in the process of closure removal.          The outward expansion or flexing of the skirt is facilitated by the break or disruption and reduces the hoop tension thereby permitting the snap beads to more readily disengage from an annular locking rib to make the closure easier to open in its unlocked position.
Patent CA-2114898-A1 (CA)
Title: Fall-arrest strap and fall prevention method
Inventor: VALLANCE RICHARD
IPC: A62B35/00
Filed: 1994-02-03
Abstract: A fall-arrest strap for attachment to a safety belt or harness worn by a worker or a tether to a safety belt or harness worn by a worker having one endattached to a support structure and a method for attaching the strap to a woodenbeam. A handle is at the other end of the strap for attaching the strap to the safety belt or harness worn by the worker or the tether secured thereto. Flexible support webbing is attached to the handle. The flexible support webbing has an intermediary folded-over portion secured by stitches. The stitches have less tensile strength than the flexible support webbing whereby when the worker falls, the stitches break upon application of a force less than the breakage strength of the strap, thereby absorbing shock load. The strap possesses at one end thereof attachment means to aid in attaching the strap to the support structure. The fall prevention method to secure workers to a support structure comprises passing securement means, which in the preferred embodiment are nails through one end of a flexible fall arrest strap to thereby attach the end of the strap to a beam or truss, and wrapping the strap at least once around the beam, and securing the other end of the strap to the worker. In this manner, the force exerted by the fallen worker is applied perpendicular to the direction of insertion of the securement means into the flexible strap means.

Title: Methods for establishing certifiable informed consent for a medical procedure
Inventor: RAKSHIT AMITABHA
IPC: G16H10/60
Filed: 1993-05-18
Abstract: A method for establishing certifiable patient informed consent for a medical procedure, where, in one embodiment, the patient interacts with a video training system until mastery of all required information is successfully achieved. Training techniques which permit elicitation of measurable behaviors from a patient as a guide to discerning the level of knowledge of the patient are utilized. Certification is only granted when the measurable behavior approximately coincide with the legal and medical standards for establishing informed consent. The system is capable of adapting to various medical procedures, as well as various patient attitudes and knowledge bases, while still maintaining a level of consistency throughout. In one embodiment, a minimum probability of understanding may be preset, and the training procedure will continue until the actual statistical probability of understanding is at least equal to the preset minimum. An interactive nature of the system is present in the present system for facilitating the training process and continuously monitoring the patient's knowledge.
