Title: Dispositif pour serrer un raccord a vis dans un implant dentaire ancre dans l'os
Inventor: KVARNSTR M BJARNE
IPC: A61C8/00
Filed: 1996-12-23
Abstract: L'invention concerne un dispositif à utiliser conjointement avec un outil pour serrer mécaniquement un raccord à vis dans un implant dentaire ancré dans l'os, sans que le tissu entourant l'implant ne subisse de contrainte. Le dispositif comporte un premier élément tubulaire (6) destiné à être bloqué en rotation sur l'implant, et un second élément en forme de bras (8) relié rigide au premier élément et s'étendant essentiellement à angle droit par rapport à ce dernier. Le bras est doté d'une fourche en U (7) qui interagit avec l'élément stationnaire (1) de l'outil de serrage de sorte que tout mouvement de rotation indésirable soit empêché pendant le serrage du raccord à vis. La fourche en U (7) est montée pivotante sur le bras, ce qui permet la relaxation des contraintes et le dégagement de l'outil de serrage une fois le serrage terminé.

Title: Methods for recovering raw meat from the head-shells of crustaceans, e.g., lobsters and use thereof for stuffed crustaceans, e.g., lobster and stuffing so-provided
Inventor: HONG LILY
IPC: A22C29/02
Filed: 1999-07-16
Abstract: Procedures are provided herein for the optimization of the utilization of crustaceans, e.g., whole lobsters, through the inclusion of under-utilized components. The procedure involves firstly, initiating the detachment of the raw edible deep-shoulder myotomal meat from deep-shoulder cartilaginous skeleton attachment. This may be accomplished either by immersing the head-shell in a solution of protease enzymes, or subjecting the head-shell to at least one freeze-thaw cycle. Then, the so-treated head-shell is subjected to vacuum aspiration to remove, and to recover, the raw meat fraction. Procedures are further-described for the utilization of such recovered raw meat fraction, e.g., to provide stuffing and to provide stuffed crustaceans, e.g., lobsters.
