Title: Loading Device Having Multiple Tongs for Handling Lumber and the Like
Inventor: FOURNIER GERMAIN
IPC: B23Q7/00
Filed: 1996-09-16
Abstract: The loading device of the present invention is adapted for the high speed handling of lumber pieces, wherein the lumber pieces are fed side-by-side in bulk to the loading device by an inlet conveyor and are delivered by the loading device in a substantially constantly spaced relationship onto an outlet conveyor which carries the lumber pieces to another station, e.g. a classifier. The loading device comprises solely motorized mechanical components, including a number of synchronized camactuated tongs for picking up, grasping and transferring the lumber pieces from the inlet to the outlet conveyor. The tongs are mounted on a rotatable wheel and each displaced by a first cam system between open, closed and open positions thereof during each rotation the wheel. A second cam system operates stoppers at the inlet side of the loading device to allow the one-by-one access of the lumber pieces to the loading device with both cam systems being synchronized such that the lumber piece accesses the loading device as the tong appears at the inlet side, wherein the tong is in its open position prior to reaching the inlet side and is adapted thereat to pick up a lumber piece and to then move to its closed position until reaching the outlet conveyor where the tong is returned to its open position thereby releasing the lumber piece onto the outlet conveyor.

Title: Sediment classification system
Inventor: LAMBERT DOUGLAS N
IPC: G01V1/38
Filed: 1995-04-14
Abstract: A computer (10) driven system which receives time-binned echo strength data (85), and which, for each series of echo strengths received, stores the echo strength data in computer memory (71), and automatically associates with that data the latitude, longitude and time at which the data were generated. From these data, the algorithm classifies the sediments, which produced the echo strengths, determining such parameters as sediment acoustic impedance, porosity, attenuation, grain size, density, acoustic velocity and shear strength. System software can produce additional result files in which these properties are associated with corresponding echo strength data. Both the raw and reduced data are displayable in human readable form, preferably on a computer monitor, for operator review. System software can also generate navigation plots which trace on a map, preferably on computer monitor (26), points at which data are taken, and the bottom sediment at those points. System software (22), in conjunction with standard computer graphics packages, can display the data in all these files, both after the fact and in near real time for operator review.

Title: Fusogenic liposomes and methods of making and using same
Inventor: BAILY AUSTIN
IPC: A61K9/127
Filed: 1994-04-12
Abstract: A liposome composition is provided which contains a liposome having: (i) an outermost lipid bilayer containing, in addition to a neutral, bilayer-preferring lipid, a fusion-promoting effective amount of an ionizable lipid having a protonatable, cationic headgroup and an unsaturated acyl chain; and (ii) a compartment adjacent to the outermost lipid bilayer which contains an aqueous solution having a first pH. External to the liposome in the composition is an aqueous solution having a second pH. The first pH is less than the pKa of the ionizable lipid in the outermost lipid bilayer and the second pH is greater than the pKa of the ionizable lipid in the outermost lipid bilayer, such that there is a pH gradient across the outermost lipid bilayer and the ionizable lipid is accumulated in the inner monolayer of the outermost lipid bilayer in response to the gradient. The liposome can be fused in a controlled manner to another lipid bilayer, for example, the plasma membrane of a mammalian cell, by degrading the pH gradient when fusion is to occur, such that the ionizable lipid is neutral, evenly distributed in the outermost lipid bilayer and, fusogenic. Controlled fusion can be used to control the delivery of a biologically active agent entrapped in the liposome into a cell.

Title: Optimum carton hold-down element for rotary feeders
Inventor: MONCRIEF FRANK
IPC: B31B50/76
Filed: 1996-03-13
Abstract: A hold-down element (40) for a rotary feeder has a curved elongated member for continuously contacting an article during rotation of a rotary head (20). The curvature of the hold-down element is selected so that the distance from the elongated member to the rotary head increases from the point of initial contact to the final contact point on the elongated member. The holddown element preferably maintains contact for at least 20.degree. of rotation of the rotary head, and thus maintains contact with the article for an extended period of time. The hold-down element is attached to a vacuum shaft (48) on the rotary head, and is prevented from rotating relative to the vacuum shaft by a keyway (43) on the hold-down element and a key on the vacuum shaft. The hold-down element, however, is permitted to travel transversely along a longitudinal axis of the vacuum shaft in order to accommodate different shaped articles.

Patent CA-2199002-A1 (CA)
Inventor: EPPSTEIN JONATHAN A
IPC: A61B5/157
Filed: 1996-08-29
Abstract: A method of enhancing the permeability of the skin to an analyte for diagnostic purposes or to a drug for therapeutic purposes is described utilizing microporation and optionally sonic energy and a chemical enhancer. If selected, the sonic energy may be modulated by means of frequency modulation, amplitude modulation, phase modulation, and/or combinations thereof. Microporation is accomplished by (a) ablating the stratum corneum by localized rapid heating of water such that such water is vaporized, thus eroding the cells; (b) puncturing the stratum corneum with a micro-lancet calibrated to form a micropore of up to about 1000 µm in diameter; (c) ablating the stratum corneum by focusing a tightly focused beam of sonic energy onto the stratum corneum; (d) hydraulically puncturing the stratum corneum with a high pressure jet or fluid to form a micropore of up to about 1000 µm in diameter, or (e) puncturing the stratum corneum with short pulses of electricity to form a micropore of up to about 1000 µm in diameter. A dye with an absorption maximum matched to the wavelength of a pulsed light source can be absorbed into the stratum corneum to concentrate the energy of the pulsed light source and aid in ablation of the stratum corneum. Alternatively, a hot wire can be caused to contact the stratum corneum.

Title: Roll support hub braking mechanism
Inventor: LISSONI ADELIO
IPC: B65H23/06
Filed: 1995-02-24
Abstract: An improved braking system for a rotatable roll support hub for a roll product of web material is described that is capable of providing a smoother and progressive braking action which uses a less powerful compression spring. This can be achieved by utilizing a friction element that has frustoconical shaped friction surfaces. Specifically, the friction element comprises a frustoconical disc that floats between a similar frustoconical surface that rotates with the roll support hub and an opposite similar frustoconical surface on the pressure disc. Preferably, a rim flange is provided as part of the pressure disc that forces the friction element into wedged engagement on the frustoconical friction surface of the roll support hub. The advantages are achieved for providing a smoother progressive braking action which is applicable to any roll support hub on which a controlled braking force is desirable. Such may include manual tape dispensers or any other roll support hub for any roll of web material which is associated with an automatic, semiautomatic, or manual dispensing or applying apparatus.
