Abstract: An improved pressurizing sprayer removably attaches to the threaded neck of a container and includes a main body having a handle portion and a head portion. The handle includes a top portion with an exposed trigger and an inside portion in which a hand operated squeeze bulb pump is fitted. The head portion houses a pinch valve which is interconnected in-between a spray nozzle and a fluid conduit. Manually squeezing the pump delivers air into the container. Manually pressing the trigger continuously or intermittently opens the pinch valve allowing the fluid to flow through the conduit and out of the spray nozzle in the form of a pre selected spray pattern. Relatively few pump strokes are required to pressurize the sprayer. The tasks of aiming, spraying, and pressurizing can be completed simultaneously and with the use of only one hand.

Abstract: A reusable base cup for removable attachment to the outside exterior base of a bottle in order to prevent the bottle from tipping over when pressurized. Several inner facing flexible tabs are situated along the circumference of the top edge. Each tab is permitted to flex and conform independently to the shape of the outside wall of the bottle base while exerting a constant force. The base cup can be securely attached to different bottles with slightly varying base diameters by manually pressing the bottle base into the base cup. The base cup will remain attached to the bottle base and can be manually removed for reuse with another bottle.

Abstract: An all digital video synchronization technique wherein a microprocessor tracks the incoming video signal and synchronizes its operation by stopping at a certain point in the sync signal and restarting upon occurrence of a horizontal sync pulse.

Abstract: An anhydrous composition comprising an anhydrous emollient and an effective amount of a water-soluble guanidine salt together with an effective amount of a water-soluble inorganic oxide. Upon the mixing of an effective amount of water with the composition, guanadine hydroxide is formed which is used to treat the hair.

Abstract: A microprocessor-based video sync generation technique wherein the microprocessor stores a table of transition times and at each time supplies appropriate control signals to a digital-to-analog converter to cause it to generate the desired sync waveform.

Abstract: Compositions and methods for curling hair and for straightening hair are disclosed, wherein the compositions contain, as the principal active ingredient thereof, guanidine hydroxide. The guanidine hydroxide may be conveniently prepared by reacting calcium hydroxide and guanidine carbonate.Hair is curled by contacting the hair with the composition while the hair is on curlers, or otherwise maintained in a curled configuration. After the desired treatment time, the hair is rinsed and neutralized, with long lasting curls of the so-called "permanent wave" nature resulting.Hair may be straightened by contacting the hair with the composition and maintaining the hair in a generally straight configuration over at least a portion of the time that the hair is contacted by the composition. Thereafter the hair may be rinsed and neutralized.

Abstract: A method and composition for curling hair and for straightening hair is disclosed, wherein the method involves the application of guanidine hydroxide to the hair. The guanidine hydroxide is prepared by mixing together in an aqueous medium at least one water-soluble guanidine salt and at least one particulate, strong-base, quaternary ammonium, hydroxide-form ion-exchange resin. After the mixed components have had a chance to undergo ion exchange, to form an aqueous solution of guanidine hydroxide, the guanidine hydroxide composition is separated from the ion-exchange resin, and applied to the hair withinin 48 hours. The treatment with guanidine hydroxide causes the hair to maintain a desired configuration by conducting the treatment with the hair in the desired configuration during at least a portion of the time that the hair is in contact with the guanidine hydroxide solution.

Abstract: Systems and methods for curling hair and for straightening hair are disclosed, wherein the systems contain, as a principal active ingredients thereof, guanidine hydroxide, together with an ion exchange resin. The guanidine hydroxide is prepared by mixing together in an aqueous medium at least one water-soluble guanidine salt and at least one particulate, strong-base, quaternary ammonium, hydroxide-form ion-exchange resin. After the mixed components have had a chance to undergo ion exchange, the composition is applied to hair which is maintained in a desired configuration, and after the composition has been in contact with the hair for an effective time the composition is removed from the hair, thereby causing the hair to maintain such desired configuration.

Abstract: A stable, aqeuous depilatory composition is disclosed, wherein the composition contains, as the essential active ingredients, alkali metal silicates, alkali earth metal salts of .alpha.-and/or .beta.-mercapto carboxylic acids and thiourea.The composition is useful in removing facial hair (beard) with the hair being removed in a short period of time, for instance 4 - 7 minutes or so, depending on toughness of the beard and with minimal incidence of skin irritation in the average user.
