Title: Dehydrated liposomes
Inventor: JANOFF ANDREW S
IPC: A61K9/60
Filed: 1985-08-02
Granted: 1990-06-12
Abstract: ABSTRACT OF THE DISCLOSURE 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; and (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 lipid) 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 ma-terials, e.g., drugs, into the liposomes.

Title: Tamperproof water meter
Inventor: SUTHERLAND RAY
IPC: G01F15/00
Filed: 1986-04-30
Granted: 1991-01-15
Abstract: TAMPERPROOF WATER METER Abstract of the Disclosure A water meter is provided with a retaining ring which is mounted on the top wall of the main case and secured thereto by means of a connection requiring limited rotary motion for engagement.  A bonnet within which the register housing is enclosed is mounted on the retaining ring by a similar rotary motion whereby removal of either the bonnet from the retaining ring or the retaining ring from the main case requires only limited rotary motion in the reverse direction.  To prevent removal of the register by unauthorized individuals such reverse rotary motion is prevented by a locking pin which projects through the bonnet, the retaining ring and into a recess in the main case whereby relative rotary motion between the bonnet and the retaining ring and the retaining ring and the main case is prevented.  Once in place the pin cannot be removed without visible deformation or destruction thereof.

Abstract: MACROSCOPICALLY EXPANDED THREE-DIMENSIONAL POLYMERIC       WEB FOR TRANSMITTING BOTH DYNAMICALLY DEPOSITED AND STATICALLY CONTACTED FLUIDS       FROM ONE SURFACE TO THE OTHER     ABSTRACT A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity of fluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface of said web using the dynamic and gravitational head of the fluid as a primary driving force. Each of the macroscopic cross-section capillary networks originates as an aperture in the first surface of the web and has a continuously interconnected sidewall extending in the direction of the second surface of said web. The continuously interconnected sidewall terminates to form at least one aperture in the second surface of said web, whereby the bulk of the dynamically deposited fluid is transmitted from the first surface to the second surface of said web by the macroscopic cross-section capillary networks. The first surface of the web in which the macroscopic cross-section capillary networks originate further includes a multiplicity of fluid-handling capillary networks which are substantially smaller in cross-section than the macroscopic cross-section fluid-handling capillary networks. The smaller fluid-handling capillary networks exhibit a degree of capillary suction sufficient to transmit static fluid contained on the surface of objects which contact the first surface of said web generally in the direction of the second surface of said web by capillary attraction. In a preferred embodiment the smaller fluid handling capillary networks are oppositely oriented from the macroscopic cross-section capillary networks to provide improved visual and tactile impression as well as to enhance the volume of dynamically deposited fluid which flows into the macroscopic cross-section capillary networks.
