Title: A grooming implement
Inventor: CANN DAVID VICTOR
IPC: A46B7/06
Filed: 1997-12-12
Granted: 2004-03-23
Abstract: The invention relates to a personal grooming implement, such as a toothbrush (1), comprising a segmented head (2), wherein the segments (6) are essentially connected to each other only by an elastomer (7 ), the elastomer preferably being fused to the adjacent segments. In a preferred embodiment the implement is a toothbrush having segments (6) disposed longitudinally along the brush head (2), the segments being connected to each other only by an elastomer which is fused to each segment. The strength of adherence of the elastomer to the segments is such that the head can be repeatedly flexed in each direction without loss of structural integrity. In this manner the use of hinges to connect the segments can be avoided, thus improving the reliabilit y and ease of manufacture of the brush and providing greater flexibility in head design.

IPC: E21B7/08
Filed: 1999-07-12
Granted: 2005-02-15
Abstract: A drilling direction control device, improvements in drilling direction control devices, methods for orienting a rotary drilling system, and methods for rotary drilling. The drilling direction control device includes a rotatable drilling shaft, a housing for rotatably supporting a length of the drilling shaft, and a deflection assembly contained within the housing for bending the drilling shaft between a first support location and a second support location. The deflection assembly includes an outer ring which is rotatably supported on a circular inner peripheral surface of the housing and which has a circular inner peripheral surface that is eccentric with respect to the housing. The deflection assembly also includes an inner ring which is rotatably supported on the circular inner peripheral surface of the outer ring and which has a circular inner peripheral surface which engages the drilling shaft and which is eccentric with respect to the circular inner peripheral surface of the outer ring. Methods for orienting a rotary drilling system involve communicating a desired orientation of the drilling string to a drilling direction control device and then actuating the drilling direction control device to deflect the drilling shaft to reflect the desired orientation of the drilling shaft. The desired orientation of the drilling shaft may be communicated directly to the drilling direction control device or to the drilling direction control device through a drilling string communication system.

Abstract: A hand-held water purification system in-cludes a pen-light sized ultraviolet lamp (12) that is enclosed in a quartz cover and is powered by a battery and associated ballast circuitry. The bat-tery and ballast circuitry are connected to the lamp by switches that are under the control of a liq-uid-level sensor. The sensor connects the battery, the ballast circuitry and the lamp once the sensor determines that the ultraviolet lamp is fully im-mersed in the water. If the container (32) that holds the water is relatively large, the lamp and quartz cover end (16) of the system are used to stir the water, to ensure that all of the water comes sufficiently close to the ultraviolet lamp (12).

Abstract: An attachment between a monitoring device and an innerliner of a tire includes the use of an epoxy adhesive that bonds the monitoring device directly to the inner surface of the innerliner of the tire. The innerliner is first roughened in a manner that provides a roughened portion of the innerliner without removing the entire thickness of the innerliner. The entire thickness of the innerliner is not removed because the innerliner is preferably more than 1/16 of an inch thick. The thickness of the innerliner allows the rigid cured epoxy to bond the monitoring device to the inner surface of the innerliner while allowing the innerliner to flex with the tire so as to not break the seal between the rigid epoxy and the innerliner. The monitoring device is preferably located at a low flex area of the tire to help avoid the problem of the innerliner flexing.

Pressurized fluid from a source is supplied to an input port provided on the manifold. A  solenoid valve is mounted on the manifold and is selectively operable in a first and second mode modes to control the flow of pressurized fluid therethrough to a clutch actuation port of the power take-off unit. Low pressure fluid is supplied from a low pressure port of the: manifold to the power take-off unit so as to provide internal lubricating fluid thereto. A temperature switch and a pressure switch may also be mounted directly on the: manifold. A bracket or other mechanism may be provided to mount the manifold on a support surface, such as on a side rail of a frame assembly for the vehicle.  Alternatively, the plurality of internal passageways may be formed within a housing for the power take-off unit. Thus, the solenoid valve, the temperature switch, and the pressure switch are all mounted directed on the housing of the power take-off unit, and no external mounting bracket or other mechanism is required.

Title: Reduction of sperm sensitivity to chilling

IPC: A61D19/02

Granted: 2009-02-03
Abstract: A method of preserving sperm of domestic animals especially porcine and bovine. Cryopreserved boar spermatozoa is much less fertile than that of other species, which could be due to damage to sperm membrane lipids during the cryopreservation process. Incorporation of selected lipids improves the survival of boar spermatozoa following cryopreservation. Liposomes were made from lipids extracted from head plasma membrane (HPM) of boar spermatozoa or from selected lipids (SL) which contained specific phospholipids and fatty acyl chains. SL and HPM improved sperm viability (SYBR-14 and propidium iodide) and motility during cooling to 5°C, with SL~ egg yolk better than or equal to HPM (P<0.05). Post-thaw, egg yolk showed a strong cryoprotective effect. Compared to BPM, SL-treated sperm had higher post-thaw viability, progressive motility and total motility in the extender including egg yolk and higher viability in the extender excluding egg yolk (P<0.05).

Abstract: An apparatus and process for hiding the secondary image within the primary image and generating a high quality hard copy of the unified elemental image of a variety of media. The process comprises the steps of rasterizing the first image into a first elemental image and rasterizing the second image, compensated with its own inverse, into a second elemental image. The first elemental image and the second elemental image are merged into a unified elemental image based on a predetermined decoding and compensating principle, resulting in the second elemental image being hidden within the first elemental image. An output image is created based on the unified elemental image where the primary image is visible to an un-aided eye while the secondary image is hidden from the un-aided eye.

Abstract: A method for providing a quantity of pre-paid telephone time from an automated teller machine (ATM) or a point-of sale device (POS terminal), to a patron of either of such device. PIN numbers, obtained from a telephone service provider and each designating a pre-paid quantity of telephone service time, are made available to the ATM  or POS terminal. The patron is queried by the device if he/she wishes to purchase telephone time. Upon selection of a quantity of pre-paid telephone time by a patron and payment for such purchased quantity of time, the device selects a particular PIN number having an associated quantity of telephone time corresponding to the quantity of telephone service time purchased by the patron, and provides such PIN number to the patron. In a preferred embodiment the PIN number is provided to the patron by being printed out on the ATM's existing account statement printer, or on the account statement printer of a POS terminal if a POS device is alternatively employed. An ATM to permit patrons of such ATM to purchase a quantity of telephone time from one of a plurality of telephone service providers is further disclosed.
