Abstract: An apparatus for accurately monitoring motor movements attributable to seizures and convulsions of patients having epilepsy or other seizure disorders, and motor movements attributable to periodic leg movements, tremors, respiration, mechanical cardiac functions, or any other motorics during periods of sleep. This monitoring function is achieved without attaching any detection apparatus to the patient. Embodiments measure patient movements essentially by relating mattress displacement to such motor movements. The preferred embodiment is constructed with a geophone configuration intended to receive an analog signal corresponding to mattress movement and to communicate this signal to an electrically interconnected detection assembly for monitoring and recording the patient's pattern of body movements. Other suitable movement sensing devices such as devices based upon piezoelectric, fiber optics, microwave, infrared, and ultrasound phenomena may be used either in addition to or instead of geophones.

The invention also includes alumino-silicate derivatives of the general formula MpAlqSi2Or(OH)sXt.uH2O as well as alumino-silicate derivatives of the general formula MpAlqSi2Or(OH)s.uH2O.

Abstract: The formation of new materials in the form of alumino-silicate derivatives from 2:1 layer clay materials which are obtained by the chemical modification of 2:1 layer clay minerals by reaction with a salt having the formula MX wherein M is ammonium ion or alkali metal cation and X is a halide. The new materials have the following characteristics: (a) an amorphous x-ray diffraction signal manifest as a broad hump using x-ray powder diffraction between 22° and 32° 2&thgr; using CuK&agr; radiation; and (b) the presence of primarily tetrahedrally coordinated aluminum.

Abstract: A boil-in-bag package for the storage and cooking of food items includes an elongated rectangular shaped bag having an inside and an outside wall, a closed top end and an open bottom end. A handle section is adjacent the top end of the bag section, with the handle section having an upper and a lower portion and a first and second side. The upper portion of the handle section includes an opening sized and shaped for receiving a lifting utensil. A sealing/release mechanism is positioned on the handle section and is configured to releaseably close the open bottom end of the elongated bag section contiguous with the handle section thereby forming a U-shaped package configured to allow a through-flow of fluid between the inside walls of the U-shaped package. The sealing/release mechanism is further configured to allow for the release of the open bottom end from the handle section without contacting the elongated bag section.

Abstract: A process for the preparation of a modified kaolin from a kaolin group mineral which includes expansion and contraction of layers of the kaolin group mineral. The layers comprising one Si-tetrahedral sheet and one Al-octahedral sheet. The expansion and contraction may be initiated by initial intercalation of a reagent which can penetrate kaolin layers to reach an interlayer region therebetween to form an intercalate. Subsequently, the intercalation nay be followed by de-intercalation which involves the removal of the reagent. By the above process, there is provided crystalline modified kaolins having the following properties: (i) an increased interlayer space compared to corresponding kaolin group minerals; (ii) an increased susceptibility to intercalation by cations, anions or salts compared to corresponding kaolin group minerals; and (iii) an increased exfoliated morphology compared to corresponding kaolin group minerals.

Abstract: A rolled paper embossing dispenser in which the paper is embossed and from which the paper is simultaneously dispensed. The dispenser includes a nip formed by a first embossing roll and a second embossing roll, both rotatably mounted within a cabinet. The first embossing roll has a plurality of spaced-apart annular bands with each annular band including discrete, spaced-apart knuckle projections extending radially from the roll. The second embossing roll includes annular slots and annular extensions arranged in alternating relationship with each annular slot having sufficient width to receive the knuckle projections without contacting any portion thereof as paper is fed through the nip and embossed. A lever or crank is provided for a user to rotationally drive one of the embossing rolls, the other embossing roll rotating only in response to the paper being drawn through the nip such that rotational slippage of one roll with respect to the other will not result in breaking or tearing the web.

Abstract: An apparatus that controls the swinging of a frame (50) and the rotation of a turret (52) in an automatic web rewinding machine. The frame (50) is pivotally mounted in the machine and a turret (52) including a plurality of rotatable mandrel assemblies (56) is mounted for rotation within the frame (50). The control apparatus includes an indexing device (66) having an output shaft (70) that undergoes intermittent rotation in response to continuous rotation of an input shaft (68). One drive means (80), coupled and responsive to the output shaft (70) of the indexing device (66) provides intermittent rotation of the turret (52). A second drive means (78) is provided to control the rotation of the cam (60) in order to minimize the overlap of the rotation of the cam (60) with the dwell time of the turret (52). The optimum condition occurs when the cam (60) rotates only when the turret (52) is indexing and when the cam (60) does not rotate at all while the turret (52) is dwelling.
