Abstract: Abstract of the Disclosure An assembly for providing support to a component, such as an ultrasonic component, including converters, boosters and horns which are subjected to continuous and repeated impacts and stresses.  Such devices generally have integral nodal flanges for support purposes.  In this assembly, shock-absorbing means are placed on each side of the nodal flange.  A grip ring assembly is then bolted or otherwise removably fastened, together over the shock-absorbing means and nodal flange,  compressing the shock-absorbing means.  The component is prevented from rotating with respect to the grip ring assembly by pegs which are driven through holes provided in the grip ring assembly and into slots formed lengthwise in the nodal flange.  Hence the flange itself, via the shock-absorbing means, absorbs all of the lengthwise force applied to the component by the grip ring assembly, and the pegs are required to absorb none of it.  Consequently the problem of breakage of the pegs due to excessive lengthwise force thereon, and the resultant waste of the booster having such broken peg, is solved by the invention disclosed herein.

Granted: 1993-08-03
Abstract: Abstract of the Disclosure A large thin web having a coherent crystal morphology throughout its extent is made on a continuous basis by drawing a meniscus of the web material from a hot melt thereof onto a heated support surface which moves relative to the melt so that the liquid is distributed as a thin liquid film over that support surface.  The moving support surface advances the film progress-ively past a chiller which establishes a chill zone at the surface of the film which cools the film material at an isothermal front or boundary therein to a temperature below the melting point of the material so that the material solidifies.  Also, a crystal seeding bar is located at the chill zone which is brought into contact with the film just ahead of the front so that when the film solidifies in the chill zone it assumes the crystal morph-ology of the seeding bar.  The solidified film that is peeled from the support surface constitutes the finished web, while new mater-ial drawn from the melt is added to the support surface upstream from the chill zone so that the process is continuous.  Method and means for controlling the process are also disclosed, as are vari-ous articles and structures made from such webs.  Also disclosed are means for depositing additional layers of material on the web while preserving a compatible crystal morphology throughout the entire plural-layer structure.

Title: Power supply with regulated output voltage

IPC: H02M3/335
Filed: 1987-11-30
Granted: 1992-01-14
Abstract: POWER SUPPLY WITH REGULATED OUTPUT VOLTAGE            Abstract A power supply circuit for use with telecommunication subscriber lines provides a substantially constant power output over one range of load impedances and a substantially constant voltage output over a range of load impedances greater than a critical impedance. The circuit employs a transformer which includes a sense winding for sensing output voltage across the load. For load impedances below the critical value, the current into the primary of the transformer is controlled by means of a current sensing device sensing the amount of primary current. However, for load impedances greater than the critical impedance the output of the sense winding controls and current to the primary is reduced to avoid the output voltage from rising substantially even in the event of an open circuit load condition. In one embodiment, a supervisory circuit provides a signal indicative of the on-hook and off-hook staus of the subscriber line by sensing primary current flow. In an alternate embodiment, a supervisory circuit provides an indication of the on-hook and off-hook states of the subscriber line in response to a signal derived from the sense winding voltage.

Title: Electromagnetic relay with pivotable armature
Inventor: NAGAMOTO MITSUKI
IPC: H01H51/22
Filed: 1988-03-18
Granted: 1991-12-10
Abstract: ABSTRACT  A relay has a contact assembly and an electromagnet with a L-shaped pivotable armature rockable with its inside angle supported against a complementary yoke edge.  A base mounting the electromagnet and the contact assembly is formed with a retainer rib which is opposed to the yoke edge so as to loosely engage the angled portion of the armature therebetween but to prevent the inside angle of the armature from departing beyond an allowable distance from the yoke edge.  A movable spring included in the contact assembly is operatively connected to a first leg of the L-shaped armature so as to be driven thereby to close the contacts in response to the energization of the electromagnet.  The armature in the reset position has its free end rest on a fulcrum projection on the base and receives a return bias from the movable spring at a point inwardly of the fulcrum projection such that the return bias of the movable spring acts as a torque which causes the armature within the allowable distance from the yoke edge to pivot about the fulcrum in a direction of urging the inside angle of the armature toward the yoke edge to such an extent that, upon energization of the electromagnet, the inside angle of the armature can be firstly attracted to the yoke edge into exact coincidence therewith, ensuring an accurate pivotal movement about the yoke edge without requiring a conventional retainer spring which constantly urges the inside angle to the yoke edge.
