Patent BG-49797-A1 (BG)
Title: Device for forming a laser impulses
Inventor: NENCHEV MARIN N
IPC: H01S3/10
Filed: 1990-01-11
Abstract: The device is used in optical receiver testing systems and in master generators of laser systems for research, for example measuring controlled thermonuclear synthesis. It helps improve the form of the output pulse, which is close to rectangular. The device consists of a divider (1) of the laser pulse due to be formed, one output of which is connected through the optical delay line (10) to one input of the pulse former (7), having its second input connected to the second output of the divider (1). The divider is made up of sequentially positioned along the optical axis Pokels cell (2), controlled by synchronizer (3), connected to the input via a light divider (5), and a Glenn prism (6). The pulse former contains a Fabri-Perrault interferometer (7) with a gap filled in with a brightening solution, having its upper layer, lying within the focus of a cylindrical lens (16), in direct contact with the second output of divider (1). The first input of the pulse former (7) represents a section of the upper edge of one of the mirrors (8) of the interferometer (7), so that the emission passes through the focus of the cylindrical lens (16).

Title: Detection d'objets ferromagnetiques approchant d'un aimant
Inventor: HOULT DAVID I
IPC: F02P17/00
Filed: 2003-04-15
Abstract: Cette invention concerne un appareil servant à détecter un objet ferromagnétique potentiellement dangereux porté par inadvertance par un individu s'approchant de l'aimant d'un système (14) d'imagerie par résonance magnétique. Cet appareil utilise le champ de franges (16) de l'aimant et génère des éléments de guidage (11) définissant une trajectoire que l'individu est prié de suivre. Cette trajectoire (11) est sensiblement ou approximativement parallèle au champ au niveau de la trajectoire. Au moins une bobine de détection et habituellement deux ensembles de bobines (12, 13) de détection sont disposés sur les côtés respectifs de la trajectoire (11) de manière que le déplacement de l'objet ferromagnétique dans le champ de l'aimant provoque la génération d'une tension dans la bobine de détection.

Abstract: ABSTRACT        An improved hinge assembly for a personal computer system.          The hinge is comprised of a tubular portion which is rigidly connected to the cover unit of the computer. A part of the tubular hinge is left open to form a passageway into the cover unit. The tubular portion rotates relative to the main body section of the computer. The tubular portion has a longitudinal section removed from near its mid-point, forming a gap. This gap is closed by a curved cover element. The cover element is held stationary with respect to the main body section of the computer.  Thus, when the cover unit is opened, the tubular portion rotates relative to the cover element. A cable connecting the electrical components in the cover unit to the main body section passes through an opening in the curved cover element, is bent, travels through the tubular section, parallel to its central axis, is bent again and passes into the cover unit.
