Patent EP-0190315-A4 (EP)
Title: Dehydrated liposomes.
Inventor: JANOFF ANDREW S
IPC: A61K31/7042
Filed: 1985-08-07
Abstract: Dehydrated liposomes are prepared by drying liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes. Freezing of the liposome preparation prior to dehydration is optional. Alternatively, the protective sugar can be omitted if : (1) the liposomes are of the type which have multiple lipid layers ; (2) the dehydration is done without prior freezing ; (3) the dehydration is performed to an end point which results in sufficient water being left in the preparation (e.g., at least 12 moles water/mole liped) so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration gradients capable of generating transmembrane potentials can be created across the liposome membranes either before or after dehydration, and the transmembrane potentials resulting from these gradients can be used to load charged materials, e.g., drugs, into the liposomes.

IPC: C08L25/06
Filed: 1990-06-04
Abstract: L'adjonction à des polystyrènes à résistance élevée aux impacts de quantités efficaces de polystyrènes bromés à faible poids moléculaire permet d'obtenir de manière inattendue une bonne rétention des propriétés des polystyrènes en même temps qu'une propriété ignifuge voulue, par exemple UL-94 VO. Par contraste, des polymères de styrène bromé de poids moléculaire élevé (ayant un degré de polymérisation égal à 2000) ne transmettent pas à des polystyrènes à résistance élevée aux impacts une bonne qualité de rétention de propriétés telles que la résistance aux impacts et la dureté. Le degré de polymérisation des polystyrènes bromés décrits est généralement compris entre 3 et 20 environ et leur halogénation peut varier considérablement. Ces polystyrènes à résistance élevée aux impacts, mélangés à ces polystyrènes bromés à faible poids moléculaire, peuvent être aisément traités par des équipements classiques.

Inventor: BUHOT JOHN WILLIAM MEAT RESEAR
IPC: A22B5/16
Filed: 1993-03-24
Abstract: A process and apparatus for removing a hide (20) from an animal carcass (10). The animal carcass is initially opened to provide an edge (21) of the hide and the edge is pulled in a direction (PP) tranverse to the longitudinal direction (LL) so as to separate the hide progressively from the carcass until a strip of hide (25) remains attached along the spine. The strip of hide (25) is then cleared by moving a clearing means (40) along between the carcass and the strip of hide. During both hide pulling and clearing, the carcass (10) is supported in the supine position with the anterior end (16) of the carcass lower than the posterior end (15). During pulling, the line of dislocation (16) of the hide from the carcass is maintained substantially parallel to the longitudinal direction (LL). The direction (PP) of application of the pulling force is maintained so that the hide (20) is essentially peeling back upon itself away from the subcutaneous tissues of the carcass. Tension is applied to the hide in the longitudinal direction (LL) after the step of hide pulling and before commencement of the longitudinal clearing step. The hide (20) is pulled from the head (14) at the end of the step of clearing the strip of hide (25).

Title: Method for manufacturing magnetostriction type torque sensor shaft, and the shaft.
Inventor: ISHINO RENSHIRO
IPC: G01L3/10
Filed: 1993-08-23
Abstract: In the surface of a shaft base material, a knurling groove is made in the direction inclined to the direction of the shaft axis, and further, a heat treatment is applied. Then, on the surface of the shaft base material including at least the knurling groove, a magnetostrictive layer is formed by plating, flame coating, or the like with a material which has a small crystalline magnetic anisotropy and a large magnetostriction constant. It is preferable that the magnetostrictive layer is of an FeNi alloy plating layer, and the content of Fe in the alloy layer is 0 % or more and 25 % or less. In such a way, it is possible to obtain a sensing shaft having an extremely high-performance magnetostriction type torque sensor. In order to enhance the adherence between the shaft base material and the magnetostrictive layer, it is preferable to subject the surface of the shaft base material to a treatment such as shot peening or nickel strike plating before the formation of the magnetostrictive layer. By this surface treatment, it is posible to obtain a torque sensor having an excellent durability.
