Patent CA-2002251-A1 (CA)
Title: Hair brushing device
Inventor: BEAGLE VERLYN W
IPC: A46B5/00
Filed: 1989-11-06
Abstract: ABSTRACT          The present Brush will primarily be used for grooming hair.            Other brushes are commonly known to brush the hair from only one side and are usually of a rigid design.  Other brushes do not afford the user, a "double-sided", "user-controlled" and "vice-like-effect", brushing action; which could afford enhanced hair positioning and styling control".          The present hair brush overcomes the stated shortcomings of known grooming brushes.            The present brush operates with a vice-like action, due to the incorporated "bend-in-two" flexible jointing agent which lies between the two recesses of the brush.  This action is initiated whereby the user holds said brush by placing the fingers into the first recess of the brush and the thumb into the second recess of the brush.  This affords a "user-controlled" "vice-like" action, through which the user will control the amount of tension thereby passed along to the hair to be incorporated as a brushing action.            The present brush further affords the user the option to use this brush in a similar manner as known brushes, whereby the user may decide NOT to bend the brush at the flexible jointing agent during use.

Title: Electrically-tunable bandpass filter
Inventor: THOMAS GARY D
IPC: H03H7/09
Filed: 1990-01-18
Abstract: ELECTRICALLY-TUNABLE BANDPASS FILTER                 ABSTRACT OF THE DISCLOSURE A bandpass filter is disclosed which may be used in a superheterodyne receiver in front of the first mixer.  The bandpass filter provides a narrow front end filter which is tuned automatically as the local oscillator frequency is changed.   In the present exemplary embodiment, a series tuned reflective notch filter is coupled to a node of a balanced resistive bridge in such a manner that the tuned circuit presents a short circuit to the node at the filter's resonant frequency to thereby assure a maximum transfer of signal from the input to the output of the circuit at a desired frequency.  At all other frequencies, the series tuned reflective notch filter will present essentially an open circuit across the node of the resistive bridge so that the node is balanced and no transmission occurs.   The inclusion of the series reflective notch filter thereby produces a bandpass characteristic from the circuit input to output.  By using back to back varactor diodes in the reflective notch filter, the center frequency of the passband can be changed by changing the tuning voltage applied to the varactors.  In the configuration of the present invention, the varactor diodes are protected from high signal levels which are not within the narrow passband of the filter.  For this reason, the filter is inherently less susceptible to the generation of intermod products than filters of a conventional design.

Title: Microelectronic ionized device for curing oral cavity diseases, method of making bristles, and toothpaste
Inventor: LING WANG
IPC: A61C19/06
Filed: 1990-02-27
Abstract: ABSTRACT         An ionized toothpaste, and a microelectronic ionized device for curing oral cavity diseases being a special kind of toothbrush comprising a brush head, brush handle and a cavity in the handle for retaining a battery.  A group of special bristles serving as a cathode at the brush head is connected in series with the battery and a metal plate which serves as an anode adjacent the brush head.  During toothbrushing, saliva and/or ionized toothpaste fills the space between the cathode and anode to form a return circuit.  When this occurs the special bristle releases rare trace elements essential for cementosis while at the same time produces a microcurrent to stimulate such soft tissues as the oral cavity and gums, thus achieving an effect of physical massage.  Consequently, various kinds of diseases of the oral cavity are cured.  The use of ionized toothpaste enhances the curing effect.  The preferred form of toothpaste is comprised of sodium dodecanol sulphate as a froth-generator and cleaner, methyl cellulose as an excipient, sodium fluoride as an electrolyte for producing ions and as a medicated element, glycerol as a pain killer, water as a solvent, an odor remover, a flavoring essence and a sanding agent.

Title: Process for separation of semen
Inventor: RIEGER RICHARD
IPC: A61K35/52
Filed: 1990-03-27
Abstract: ABSTRACT OF THE DISCLOSURE            The present invention describes a process and the associated means that permits semen to separate into a fraction that contains almost exclusively spermatozoa with female chromosomes and a fraction that contains almost exclusively male chromosomes.  To this end, the semen is first diluted with a glucose solution and homogenized, and placed in a tube that is connected through a hose to a second tube that contains a pure glucose solution.  Gentle kneading of the tube causes the liquid to flow back and forth between the two tubes.  The whole process takes place at a temperature of 38 C to 39 C, and is continued for a period of 15 to 30 minutes.  It has been shown that when this is done, the spermatozoa with almost exclusively female chromosomes migrate into the tube, whereas the spermatozoa with almost exclusively male chromosomes remain in the tube.

The operation of the motor by the motor tester, with the vehicle engine running, causes the engine computer module to generate a pair of pulse trains in response to the changing engine conditions. A pulse train monitor, plugged into the output of the engine control module includes a pair of bi-polar LEDs, one for each of the pulse trains generated by the engine control module.  The bi-polar LED for each pulse train will alternately flash without both LEDs being  off  at  the  same  time  in  response  to  an uninterrupted pulse train.

In a specific implementation the systems and methods, the target object comprises a coin and the illumination and evaluation techniques are used to accurately objectively evaluate the numismatic quality of the coin and/or identify the coin.  Central to the illumination and evaluation techniques is the ability to apply a uniform confined beam of light to the surface of the target object to be imaged.  The confined angles of incidence of the beam of light includes a perpendicular component angle of incidence range and a parallel component angle of incidence range relative to the object surface.  The component ranges are defined such a light beam illuminates the object surface from a well-defined direction.  The direction and the extent of light beam illumination may be varied by redefining one or both of the component angle of incidence ranges.  In addition to identifying features and defects of a coin surface, the illumination and evaluation techniques are capable of imaging the surface lustre of the coin.
