  • Standing board for children
    Patent number: 7971884
    Abstract: This invention is a Standing board for prams, which is fastened to a pram with fastening beams that protrude from the Standing board and that have means for fastening to the pram on their outer ends. The fastening beams (4, 5) point forward in the Standing board's normal direction of movement and are basically parallel with it. They are also adjustable in a right angle to the movement direction, mounted on the forward edge of the Standing board with their fastenings (8, 9), which have means for retaining the fastenings in their adjusted position on the Standing board (1). The fastening beams are mounted in a manner that allows them to be twisted in the fastenings for adjustment of their angle relative to the supporting area.

  • Method for rolling compensation with wheel-mounted sensors
    Patent number: 7974806
    Abstract: A method for compensating axial misalignment between wheel-mounted alignment sensors and an axis of rotation for an associated wheel. The method compensates sensors mounted to each wheel of a vehicle simultaneously, without requiring jacking of the vehicle wheels above a supporting surface, and which only requires wheel rotational movement over an arc of 60 degrees or less. The method utilizes measurements of a change in a wheel toe angle and measurements of a change in a wheel camber angle, during a measured rotational movement of the wheel, to identify sinusoidal variation in the respective toe and camber angles during the wheel's rotational movement, from which a measure of axial misalignment between the wheel-mounted alignment sensor axis of rotation and the wheel axis of rotation is identified.

  • Use of nanomaterials in secondary electrical insulation coatings
    Patent number: 7964236
    Abstract: Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance, corrosion protection and bond strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. Resulting formulations benefit from the fact anti-settling agents need not be incorporated into the resin to keep the inorganic material suspended. Also, the rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.

  • Apparatus for and a method of binding of a perfect bound book
    Patent number: 7963733
    Abstract: Apparatus for binding perfect bound books of different thickness is disclosed where the amount of adhesive applied to the spine of the book block may be varied in relation to the thickness of the book block. An adhesive application station is provided which has a rotary driven adhesive application wheel partially immersed in a bath of a liquefied adhesive such that as a portion of the wheel rotates up out of the adhesive, the periphery of the wheel is coated with a layer of adhesive. An area of increased thickness of the adhesive if formed adjacent the top of the wheel so that upon effecting relative movement of the book block and the adhesive application station, adhesive is applied to the spine of the book block.

  • Electric motor with field weakening
    Patent number: 7960888
    Abstract: An electric motor comprising a rotor, a stator and a field weakening device. The rotor has a plurality of magnets mounted thereto, and the stator is located adjacent to the rotor and has a plurality of slots defined therein. The slots define raised teeth and are wound with electrical wiring to generate a magnetic field when the wiring is energized with current. The field weakening device is made from a highly magnetically permeable material and a comparatively lower magnetically permeable material. The field weakening device is disposed between the rotor and the stator and is selectively movable between a first position to align the highly magnetically permeable material between the teeth of the stator and the magnets of the rotor and a second position to align the comparatively lower magnetically permeable material between the teeth of the stator and the magnets of the rotor.

  • Key holder
    Patent number: 7937977
    Abstract: A key holder, comprising an external housing and an internal housing pivotably mounted inside the external housing. Keys can be retractably mounted in the internal housing with means by which keys can be extended in and out of the internal housing while the internal housing. The internal housing can be rotated in relation to the external housing when the keys are retracted into said internal housing with the keys in the internal housing held under pressure against a plug of soft material to dampen rattling when in a retracted position. The external housing includes an internal chamber sized and configured to contain a larger remote key adjacent the internal housing when the internal housing is retracted into the key holder. Other aspects of the key holder include an integral flash light or cell phone.

  • Method and apparatus for vehicle service system optical target assembly
    Patent number: 7930834
    Abstract: A method and apparatus for determining the alignment of a vehicle wheel using an optical target attached to the vehicle wheel, the optical target having a dimensionally stable shape and a plurality of target elements arranged in a known geometric and spatial configuration relative to each other. A two-dimensional image of the optical target is acquired by an imaging system to detect a plurality of target element images corresponding to the plurality of target elements arranged on the optical target. A spatial orientation of the optical target and an alignment of the vehicle wheel is then determined from the plurality of target element images and the known geometric and spatial configuration of the plurality of target elements on the optical target.
