Title: Method for increasing probability of conception of child of desired sex
Inventor: JANCIK FRANCIS J JR
IPC: A61B10/00
Filed: 1996-07-09
Abstract: A method of increasing the probability that a woman will conceive either a male child or female child, comprising the steps of determining a baseline stress level of the father, determining a baseline stress level of the mother, categorizing the determined stress levels of the mother and the father as either "high" or "low" according to a predetermined categorization criteria, and correlating the stress level of the mother and the father according to a correlation where in the case of high stress for both the mother and the father, the probability of a male child is 80% and the probability of a  female   child   is  20%, with increased possibility of infertility or miscarriage; in the case of high stress for one of the mother or the father and low stress for the other of the mother or the father, the probability of a male child is 80% and the probability of a female child is 20%; and in the case of low  stress for  both the mother  and the father, the probability of a male child is 20% and the probability of a female child is 80%. The information derived is applied by utilizing the sex probabilities according to the criteria where procuring conception of the child without alteration of the stress level of the mother and father if the indicated probability of conceiving a male or female child favors the mother and father's preference, or procuring conception of the child after altering the normal stress level of the mother and/or father to increase the indicated probability of conceiving a child of the sex preferred by the mother and father.

Title: Apparatus and method for generating product coupons in response to televised offers
Inventor: JONES CHARLES P
IPC: G06Q20/38
Filed: 1994-12-20
Abstract: Coupon information is stored in 2 memory at a cable television station. The cable television station may simultaneously transmit multiple video signals, each representing different sources of television programming, over multiple television channels on the cable network. The video signal may at times, such as during a product advertisement or other offer, include an embedded coupon identifier. A coupon subsystem at the cable television station monitors each video signal and retrieves token information from a database when it detects a corresponding embedded token identifier. The coupon information is transmitted over a data channel on the cable network. A subscriber unit at the television viewer's site receives the data channel and extracts the coupon information. The television programming aurally or visually alerts the viewer that a coupon may be generated. If the viewer actuates an input device, such as a button on a television remote control, a printer generates a coupon bearing the coupon information.

IPC: E01H1/08
Filed: 1996-12-09
Abstract: An apparatus, for brushing particulate material and the like from a surface, has a rotating brush, for example a cylindrical brush driven by hydraulic motor. The brush can be applied lightly to a surface and rotated relatively slowly, so as to brush material from the surface and project it forwardly. A strong air jet is provided in front of the brush and across the front of it, so as to pick up and entrain debris, snow, etc. brushed from the surface and blow or carry it laterally to one side. To dislodge material adhering to the bristles of the brush and prevent this from being carried behind it, a secondary, stripper nozzle is provided across the front of the brush for removing such material and causing it to drop in front of the brush. The apparatus enables the complete cleaning of a surface, for example an airport runway, in a single pass, and enables low brush pressure and speed to be provided, giving increased brush life.

Filed: 1997-01-30
Abstract: A method and apparatus for a ball and socket joint including a body member having an aperture coupled to a resilient ball container with a side wall extending from a first side of the body member to form an end portion. The side wall is disposed about at least a portion of the aperture wherein a ball disposed through the aperture is receivable in the resilient ball container. The resilient ball container has a substantially arcuate shaped inner surface portion with at least a portion of its side wall diameter less than a diameter of the ball, wherein the ball contacts and outwardly expands the side wall of the resilient ball container and draws the end portion of the resilient ball container toward the ball as the ball is inserted into and retained in contact with the resilient ball container to provide a strong, durable and tight fitting joint. A resilient retaining member disposed on the first side of the body member extends into the resilient ball container to constrict the aperture. The resilient retaining member is outwardly flexible for increasing the aperture to permit disposal of the ball through the aperture and into the resilient ball container, andl the resilient retaining member converges to constrict the aperture after the ball is inserted into the resilient ball container to retain the ball between the resilient ball container and the resilient retaining member to provide a strong, durable and tight fitting joint.

Title: Method of fabricating apodized phase mask
Inventor: EHBETS PETER
IPC: G03F1/00
Filed: 1997-02-14
Abstract: A new fabrication method for apodized phase masks, which is applicable for Bragg grating recording by proximity or contact printing, has been developed. The apodized phase mask has a surface-relief grating structure of rectangular shape with a spatially varying relief depth. The new fabrication process realizes this microstructure by combining holographic recording,  selective etching technology and the deposition of a variable thickness thin film layer. A first fabrication technique is disclosed, which realizes the apodized phase mask by means of selective etching through a variable thin film layer deposited on a substrate or on an etch stop layer. A second fabrication technique is disclosed which first realizes a conventional phase mask by etching a uniform grating structure into the substrate and then generates the relief depth modulation by deposition of a variable thickness film over the etched structure. Both fabrication methods prove to be easier and simpler to implement than previously existing approaches. They are extremely interesting for industrial fabrication, since they apply well controlled batch processes, which is essential for low cost, and feature a very accurate control and a high reproducibility of the desired apodization profile. Moreover, the proposed technology generates in comparison to previously existing methods apodized phase  mask  of  improved  optical  perfomance,  which  reduces efficiently the noise in the spectral response of the recorded Bragg gratings. In addition, a new type of intensity apodizer for the incident beam on the phase mask is disclosed for use with a phase mask of variable diffraction efficiency. The invention covers the new fabrication technology as well as the resulting microstructures of the apodized phase mask.

Abstract: A method and apparatus for separating solids from drilling fluid returning from a drilling operation wherein the apparatus comprises a separation tank divided into first and second compartments each of downwardly diminishing cross-sectional areas. There are continuous solid removal means at the bottom of each compartment. The drilling fluid is passed through a shale shaker and deposited in the first compartment where a portion of the solids settle and are removed by a clean out auger. The drilling fluid is skimmed from the first compartment and transferred to the second compartment where more solids settle and are removed. The drilling fluid then is passed through a plate separator comprising a plurality of horizontally stacked and spaced bidirectionally corrugated plates. Solids removed by the plate separator is returned to the second compartment while the remaining drilling fluid is collected and returned to the drilling operation. Flow of the drilling fluid through the apparatus is gravity-driven.
