Abstract: A method for grafting a cell in the brain of a mammalian subject is accomplished by attaching the cell to a support matrix so that the cell attaches to the matrix outer surface, and implanting the support matrix with the attached cell into the brain. Pre-ferred support matrices are glass or plastic microbeads having a diameter from about 90 to about 125 µm. The method employs cells of different types, preferably cells of neural or paraneural origin, such as adrenal chromaffin cells. Also useful are cell lines grown in vitro. Cells not of neural or paraneural origin, such as fibroblasts, may also be used following genetic alteration to ex-press a desired neural product such as a neurotransmitter or a neuronal growth factor. The method is used to treat neurological diseases such as Parkinson's disease. Alzheimer's disease, Huntington's disease, epilepsy, and traumatic brain injury.

Title: Caramel confections and processes for preparing and using
Inventor: LYNCH WILLIAM R
IPC: A23G3/46
Filed: 1993-10-25
Granted: 2003-12-30
Abstract: Caramel confections which facilitate coating, depositing, molding and baking are prepared from a finely divided solid candy phase dispersed within a continuous fat phase. These products differ from conventional caramel products which are based on sugars and milk protein and typically exhibit a chewy texture but are difficult to mold or to otherwise handle. A powdered caramel brittle material is made by sheeting, cooling and grinding a caramel prepared by cooking aqueous milk solids with sugar to a moisture level of below 6%. Preferably, from 5 to 35% of the powdered caramel brittle is mixed with 30 to 60% granulated sugar, 18 to 30% fat, and 10 to 25% milk solids. The mixture is refined to obtain an average particle size of 0.0004 to 0.0020 inches, mixed with an emulsifying agent and additional vegetable fat, and heated as necessary to reduce the moisture level.

Abstract: A door closer having a housing defining a fluid containing chamber and a fluid reservoir and including a piston supported in the chamber for movement in one and an opposite direction in response to respective opening and closing movements of a door,  A first fluid passageway defined by the housing provides communication between the chamber and the reservoir for the free passage of fluid from the chamber to the reservoir in response to initial movement of the piston in the one direction.  A second fluid passageway spaced in the one direction from the first fluid passageway contains a ball check valve spring biased to closed position for resisting the flow of fluid from the chamber through the second passageway to the reservoir. The valve is threadably adjustable relative to the housing to regulate the resistance to fluid flow.  A third fluid passageway spaced from the first passageway and disposed in bypassing relation to the second fluid passageway includes an adjustable metering orifice and provides a free flow path from the chamber to the reservoir.  The size of the metering orifice is also adjusted by threadably adjusting the valve relative to the housing.

Abstract: The printing unit has two cooperating cylinders (1, 4) which form the printing nip and which have printing saddles (2, 5) separated by cylinder pits (3, 6). The paper web (7) passing through the printing nip is transported in the pilgrim-step mode, in order to print formats adjoining one another. The two cylinders (1, 4) are angularly adjustable relative to one another, in respect of the position of their printing saddles (2, 5) cooperating in the printing nip, in a manner offset by the amount of a circumferential distance which is approximately equal to the difference between the circumferential length (S) of a printing saddle and the circumferential length (B) of a printing image. The printing zone is therefore only approximately as large as the printing image, and the print-free zone available for retracting the paper web is correspondingly enlarged.

Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. A frequency-hopping transmission method is used for the RF link. The remote units and base stations are all synchronized to a repeating pseudo- random sequence of frequencies in a band (902-928 MHz) which allows this type of transmis- sion. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange. The reply messages from the base stations to the remotes contain synchronizing information to maintain coherence with the pseudo-random sequence.

Granted: 2000-06-27
Abstract: A method of coding a speech signal is described. In accordance with the method, a plurality of sets of indexed parameters are generated based on samples of the speech signal. Each set of indexed parameters corresponds to a waveform characterizing the speech signal at a discrete point in time. Parameters of the plurality of sets are grouped based on index value to form a first set of signals which represents the evolution of characterizing waveform shape; the signals of the first set are filtered to remove low frequency components and thereby produce a second set of signals which represents relatively high rates of evolution of characterizing waveform shape. The speech signal is then coded based on the second set of signals representing high rates of characterizing waveform shape evolution. Coding of the speech signal may further be based on a set of smoothed first signals.

Abstract: The current density with which the process is used is of essential importance for the economy of a method of electrolytically treating materials. Normally only low or medium current densities are used, as the speed of replacement of consumed materials in the direct vicinity of the surface of the material for treatment has a restrictive effect on the magnitude of the current density at which a usable process result can still be achieved. However, a low current density leads to long electrolysis times and to complex treatment installations. The opportunity afforded according to the invention of improving the transfer of materials at the surface of the material for treatment consists in generating a large flow of electrolyte at the treatment point by means of rotating electrodes which are movable synchronously with the surfaces of the material for treatment, and which may be electrically polarised with respect to the material for treatment, out of which the treatment agent emerges through openings, or into which it is sucked through openings.
