International Classification:

A47C 400

US Classification:

297380

Abstract:

A portable seat carrier is provided, which consists of a seat in which a person may sit upon. A backrest to support a back of the person, is hinged to the seat. A structure extends from the sides of the seat to removably connect to the backrest for supporting the backrest in an upright position. Components are for carrying the seat and the backrest. When the supporting structure is removed from and placed behind the backrest, the backrest can be folded backwards against the seat, to form a briefcase type configuration, allowing the carrying components to transport the briefcase type configuration to another location.

Appl. No.:

7/519812

Inventors:

Richard A. Freeman - Climax NC

International Classification:

E05C 1916

US Classification:

2922515

Abstract:

An apparatus including a base member fixedly mounted to a wall support surface, including a shaft member extending orthogonally relative to the base member, with a cylindrical magnetic tip mounted thereon. The cylindrical magnetic tip is cooperative with a magnetically attractive cylindrical plate member mounted in an aligned relationship to an associated door aligned with the rod and magnetic tip. Modifications of the invention include a magnetic cylindrical tip including a threaded shank securable to a resilient pad of a door stop projection cooperative with a cylindrical tip. Further, the invention includes a cylindrical sleeve overlying the resilient projection provided with an encased magnetic member therewithin to provide a buffering action and minimize marring of an associated door in use.

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

H01S 319

US Classification:

372 44

Abstract:

A new method for increasing the modulation bandwidth of InGaAsP lasers is described herein. The method of the present invention is based on the gain enhancement doping of the lasers active layer. Lasers with highly doped active regions were demonstrated to have larger modulation bandwidths than lightly doped devices.

International Classification:

A61M 532

US Classification:

604180

Abstract:

A fastening device has a support layer, an adhesive layer on one side of the support layer, and a removable liner on the adhesive layer opposite to the support layer, the support layer having an opening therethrough. The device facilitates securing of a catheter or like assembly to a patient. A preferred catheter assembly includes the fastening device, a needle, a cannula and a hub attached to the cannula.

Abstract:

A cw laser beam of radiation superimposed upon a beam of particles, for example a beam of neutral particles, can cause substantial changes in particle trajectories when the radiation frequency is tuned near a resonant transition in the particle. The particles can be confined by, ejected from, or steered by the laser beam. The present invention teaches the range of values over which the frequency of electromagnetic radiation is to be offset from the frequency of a particle resonance, as a function of radiation power for specific wave propagation modes, to produce best focusing of the particle beam by a copropagating beam of electromagnetic radiation. Our invention takes into account the effect of random fluctuations which arise out of the quantum nature of the electromagnetic wave-particle interaction in order to determine the appropriate range of values.
