摘要:
An open tip downhole expansion tool incudes a frustoconical member having a base and a tip, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer compliance area in a material of the member along a length of the radially outer zone; and an inner compliance area in a material of the member along a length of the radially inner zone, the outer and inner compliance areas being located at different positions along the axial length of the frustoconical member, the outer and inner compliance areas each causing the frustoconical member to present a first resistance to deformation when the compliance areas are in a first condition and a higher resistance to deformation of the frustoconical member when the compliance areas are in a second condition.

An open tip downhole expansion tool including a frustoconical member having a base at a diametrically smaller portion of the frustoconical member and a tip at a diametrically larger portion of the frustoconical member, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer void in a material of the member along a length of the radially outer zone; and an inner void in a material of the member along a length of the radially inner zone, the outer and inner voids being located at different positions along the axial length of the frustoconical member, the outer and inner voids each causing the frustoconical member to present a first resistance to deformation when the voids are open and a higher resistance to deformation of the frustoconical member when the voids are collapsed.
摘要:
A slip engagable with a slip ring including a head section having an arc length, a tail section having the same arc length, an intermediate section having an arc length shorter than either the head section and the tail section connecting the head section to the tail section, and a lateral wing depending from the intermediate section.

This invention relates to an improved holder for a fishing rod. typical fishing rod holders are difficult to quickly and accurately adjust. Some even require the use of a tool to adjust. The claimed invention teaches a rod holder with a convenient adjustment mechanism that allows a user to adjust the angle of the rod holder in two planes without the use of a tool and with only one hand.

A method of deriving individual gain compensation curves for hearing aid fitting includes providing a system that detects, measures and records head azimuth for sound direction affirmation by a patient and provides a plurality of audio signals through a plurality of test sequences to the ears of the patient, including establishing a comfortable listening level of the patient, establishing binaural balance for right and left ears, establishing loudness discomfort levels of the patient, establishing thresholds-of-hearing levels of the patient and generating a binaurally balanced measurement array of measured equal-loudness levels and measured thresholds-of-hearing levels for both left and right ears.
摘要:
A net deployment system which, in one example, includes lengthy housing with a channel therein, a net folded in the channel, a lengthy bladder fixed to the housing and in the channel behind the net, attachments between the net and the bladder, and at least one inflator charge for inflating the bladder to deploy the net out of the channel.

Disclosed herein is an improved golf glove for ensuring proper grip and alignment when worn by a user while playing golf. The glove can include several restrictors located between the thumb and fingers of the glove to prevent the fingers from separating, while still allowing the ends of each finger to move freely.
摘要:
A battery powered LED lamp including an array of high-performance LEDs disposed in a lightweight directionally oriented shade. Converting electronics are provided which may include a step-down DC voltage switching regulator for converting a higher voltage of the battery power source to a lower voltage required to drive the LEDs at greater than 90% efficiency. The converting electronics may also include an LED current monitoring circuit for preventing thermal runaway of the LEDs and for reliably operating the LEDs near their maximum rating so to provide the maximum amount of brightness from the LED array and maximum battery life.
