Title: Method of producing metallic iron
Inventor: KIKUCHI SHOICHI
IPC: C21B13/00
Filed: 2002-10-25
Abstract: In a method of producing metallic iron by reducing and melting a raw material, which contains an iron oxide-containing material and a carbonaceous reducing agent, by heating, the raw material for producing metallic iron is supplied after a powder and granular atmosphere control carbonaceous material is spread on a hearth of a heat-reducing furnace.  In this case, a non-resolidificable carbonaceous material is used as the atmosphere control carbonaceous material, and thus a phenomenon that the powder and granular carbonaceous material is resolidified into a rice-cracker-like shape can be suppressed, thereby permitting solid-phase reduction with high efficiency and stable operationality.

Abstract: L'invention concerne une balance électronique pour poissons (10) comprenant un corps (11) moulé comportant une partie supérieure (48) et des parties inférieures (40/42/44/46) assurant une bonne prise en main. Un élément capteur de poids (74) à commande électronique et un écran de visualisation (32) numérique sont montés à l'intérieur du corps (11). Ledit écran de visualisation (32) est connecté électroniquement à l'élément capteur de poids (74) et lorsqu'un poisson est porté par gravité par la balance, son poids apparaît sur l'écran de visualisation (32) sous forme d'affichage numérique (B). Un ensemble d'accrochage (12) au moyen duquel le poisson à peser peut être accroché s'étend vers le bas à partir de l'élément capteur de poids (74) à travers une ouverture (120) ménagée dans le fond du corps, cet ensemble comprenant une paire de mâchoires (22/24) opposées en forme de C. Un organe d'actionnement des mâchoires (30) mobile longitudinalement est relié fonctionnellement aux mâchoires (22/24) par l'intermédiaire d'un élément de commande des mâchoires (86) et d'une cheville de rotation (96) passant à travers des fentes alignées (98) s'étendant en diagonale dans les mâchoires (22/24), ces dernières étant ouvertes lorsque l'organe d'actionnement des mâchoires (30) est déplacé manuellement vers le haut. Lorsqu'un poisson est porté par sa lèvre inférieure, maintenue entre les mâchoires (22/24) fermées sans que le poisson soit blessé, son poids apparaît sur l'écran de visualisation sous forme d'affichage numérique (B). La forme du corps de la balance facilite sa prise en main. Un ensemble de données numériques uniques peuvent être affichées de façon sélective.

Title: Locking mechanism for a hospital bed
Inventor: EDGERTON JOHN
IPC: A61G7/05
Filed: 2004-10-13
Abstract: A locking mechanism for a hospital bed is mounted on an undercarriage of the bed. The locking mechanism includes a locking pedal and an unlocking pedal, which are side-by-side one another on the undercarriage. To lock the bed in position to prevent it from rolling, one depresses the locking pedal which, through a mechanical linkage, moves a brake member having a brake pad vertically downward into contact with the floor beneath the bed, and locks the brake pad into that position. By depressing the unlocking pedal, the mechanical linkage is pulled in the opposite direction to raise the brake member and brake pad from the floor, thereby unlocking the bed.
