Abstract: The wet strength of cellulosic paper is improved by adding the combination of an amine-functional poly(vinyl alcohol) and a cellulose reactive size which is a 4 or 5 membered cyclic ester or anhydride having alkyl or alkenyl substituents of 4 or more carbon atoms.  The amine-functional polymer is preferably a hydrolyzed copolymer of vinyl acetate and N-vinylformamide in which about 1-25 mole% of the monomer units are incorporated N-vinylformamide, and the cellulose reactive size is preferably an alkyl ketene dimer or an alkenyl succinic anhydride.  A paper product is provided having improved wet-strength and containing normally 0.05 to 4.0 wt% based on the dry pulp of the additive amine-functional polymer and cellulose reactive size.  The particular compounds which represent the polymer and the size cooperate to provide improvements in wet-tensile strength for paper which could not have been foreseen from the effects of either material acting alone.

Abstract: A system and method for delivering packetized data representing radio signals to and from cell sites, and to and from a destination point via a fast packet network. Each cell site includes an interface for packetizing the radio signals and transmitting the packetized data to its destination. The destination could be a delivery point at a switch connected to the telephone network, which then converts the packetized data into a form usable by the telephone network.  Alternatively, the destination point could be another cell site, which then depacketizes the radio signal and retransmits the radio signal to another wireless communication device without connecting to the telephone network.

Title: Isolation motor mount and gasket
Inventor: NORBURY RAYMOND L JR
IPC: H02K5/24
Filed: 1994-11-23
Granted: 1998-04-28
Abstract: An electric motor mounting arrangement which permits a motor to "float" within a motor mount housing without requiring any direct contact between the housing and the casing of the motor. This is possible because of the employment of a flexible rubber-like gasket that supports the motor within the housing, so that only the gasket makes contact with the motor. The gasket also provides an air space to permit air flow around the motor for heat ventilation, due to a plurality of ribs, nodes or bumps that create the air space and, in one embodiment, due partially to a series of aligned air slots in both the gasket and in the housing. The gasket, together with a design configuration including a spacer, prevents both halves of the housing from touching the motor casing, or each other. One or more projecting nipples and lock rings may be employed to secure each gasket in its functional position in each housing.

Title: Electrostatic spray device with photoelectric switching means
Inventor: GREEN MICHAEL LESLIE
IPC: H03K17/78
Filed: 1993-11-23
Granted: 2001-12-25
Abstract: A semiconductor switching device for use in high voltage applications (typically ranging from 5kV up to about 50 kV) makes use of the well-known effect of reverse conduction in silicon diodes when exposed to light. Hitherto, photodiodes have been commercially available for relatively low voltage applications. The device disclosed herein is implemented by a high voltage diode (10) comprising a series of semiconductor junctions and a light emitting diode (12) operable to irradiate the junctions to render the high voltage diode conducting in the reverse bias direction, the high voltage diode and the light emitting diode being supported in fixed predetermined relation within an encapsulating material transmissive to the radiation emitted by the LED. The switching device finds application in electrostatic praying devices where the current demands are relatively small, e.g. up to about 2 µA, and is used for controlling high voltage production, distribution and/or shock suppression.

Abstract: A barbecue-type cooking device adapted for use with a solid combustible material. The cooking device has a substantially flat base plate. An inner peripheral wall extends substantially perpendicularly from the base plate. The inner peripheral wall has an inner wall venting aperture extending therethrough. An outer peripheral wall is also provided.  The outer peripheral wall being configured and sized to be slidably mounted outwardly relatively to the inner peripheral wall with its lower peripheral edge abuttingly resting on the base plate. In such a position, the outer peripheral wall is in a substantially contiguous and concentric relationship relatively to the inner peripheral wall. The outer peripheral wall being rotatable about its longitudinal axis relatively to the inner peripheral wall.  The outer peripheral wall having an outer wall venting aperture extending therethrough. The cooking device also having a grid member. One of the features of the device relates to its inherent ventilating components that allow for the creation of an up draft of air through the solid combustible material. When the outer peripheral wall is rotated about its longitudinal axis, relatively to the inner peripheral wall, the inner wall venting aperture and the outer wall venting aperture are adapted to be be put approximately in register with each other to modulate the flow rate of an up draft of air flowing into the open top container through the venting apertures. The cooking device also has a lid that is configured and sized so as to enclose the open top receptacle. The cooking device further having an inner rim and an outer rim extending substantially perpendicularly from the base plate. The inner rim and the outer rim defining a substantially annular channel. The channel being filled with a sand-like material. Another feature of the cooking device resides in the fact that once the lid is mounted over the container, the sand like material acts as an efficient air-tight seal for depriving the solid combustible material of oxygen and thus extinguishing the brazier.

Abstract: A Helical Bearing anchor catcher for the insertion into a well conduit to anchor well equipment in both linear directions and rotation in one direction. The device has a helical groove in either the mandrel or the drag body to accommodate the helical bearing. The helical bearing has holes within it to accommodate shear pins. The shear pins translate the linear motion from the helical bearing to the drag body. The drag body has a conical surface which contacts slips to drive them outward and grip the inner well conduit wall. Once the slip grips the inner well conduit wall the mandrel and the attached well equipment can not move linearly in either direction or rotate any further in the setting direction within the well conduit. The anchor catcher can be unset by rotating the mandrel in the direction opposite to the setting direction. The drag body, pins, and helical bearing all move downward away from the slip. The slip then moves away from the inner well conduit wall allowing the anchor catcher to be moved to a different location within or removed from the well conduit. A secondary unsetting method is provided by applying tension above that of the maximum shear force of the pins causing the pins to shear. The mandrel will move upwards along with the cone element away from the slips allowing the slips to move away from the inner well conduit wall allowing the anchor to be removed from the well conduit.

Abstract: An absorbent article, such as a generally thin, flexible sanitary napkin with a topsheet, backsheet and absorbent core is provided. The absorbent article has a means for directional fluid distribution such as a fluid directing strip positioned between the topsheet and absorbent core, and an absorbent strip positioned between the topsheet and fluid directing strip. The relationships between the sizes of the fluid directing strip and the absorbent strip are such that the width of the fluid directing strip is greater than that of the absorbent strip and the length of the absorbent strip is greater than that of the fluid directing strip, so that bodily exudates may be directed toward the ends of the absorbent core even when the sanitary napkin assumes a body-conforming shape or is otherwise distorted during use.

Abstract: A subscriber line circuit which truly implements all of the BORSCHT functions and which does not rely on an external ringing generator to provide the ringing voltage when needed is disclosed. This implementation is achieved by recognizing that supervisory and ringing signals occur in some sort of sequence and, therefore, do not have to be generated simultaneously. Based on this recognition, we provide a circuit which truly implements all of the BORSCHT functions and includes a power sectionthat generates each of the supervisory signals, e.g., -48 volts and -24 volts, and alerting signal, e.g., ringing signal, in turn and as required.
