Abstract: A method and apparatus permitting the player of a set of drums such as bongo or conga drums to alter the character of the sound produced, selectively and with complete freedom as to exactly when such effect will occur, through the use of a foot pedal which controls a set of damping elements mounted upon an adjacently located but separate damper arm and stand assembly.

Abstract: A writing tip or nib for a reservoir pen is provided comprising a thin-walled hollow element (10), e.g. of metal, having an outwardly convex end wall portion (12) defining the writing surface of the tip, and several perforations (13) extending through the end wall portion for conducting ink directly to the writing surface from inside the tip. The perforations may be at least 8 in number and measure 50-200 microns across. The outer edges of the perforations are smoothly rounded at the writing surface and the perforations taper gradually inwardly from the writing surface.

Abstract: A reservoir pen in which flow of ink from a reservoir to a nib is controlled by a valve which is actuated by the deflection of the nib during use.

Abstract: A ball-point writing instrument in which dislodging of the rotating ball as a result of accidental droppage on a hard surface is prevented by employing an ink reservoir construction designed to prevent propagation of a travelling pressure step in the column of ink above the rotating ball.

Abstract: This invention relates to the preparation and use of glucuronide derivatives of anticholinergic compounds to render them safe for use in the control of human perspiration. These derivatives, which lack mydriatic potency in the eye, are applied to the axillae where they are rendered biologically active by the action of .beta.-glucuronidase occurring naturally on the skin.

Abstract: A flexible tubular sleeve for use in conjunction with a source of heat for the application of a treating composition to the hair, said sleeve comprising an inner layer of a liquid impermeable material and an outer reservoir layer, said reservoir layer being impregnated with a hair treating composition having a melting point of about 22.degree.-100.degree. C.

Abstract: A correction fluid dispenser comprising a body member adapted to retain correction fluid, a barrel member received by the body member, a core portion extending axially of the body and barrel members, and a tip seal member disposed in a recess in the core portion and spring biased toward an orifice in the barrel member to block the orifice and prevent flow of fluid therethrough, the tip seal member being retractable against the spring bias to permit fluid flow through the orifice, the body and barrel members being operable to move the core portion, and thereby the tip seal member, into the orifice in blocking, nonretractable position.

Abstract: A writing instrument cartridge contains a loose fitting ball follower disposed within the cartridge between an end of a column of paste like ink exhibiting a yield value, and compressed gas contained in a sealed end of the cartridge. The ball follower is adapted to help peel the ink from the tube walls without contact and to prevent the gas from channeling through the ink and escaping from the cartridge past a ball point or nib during writing.

Abstract: This invention deals with compositions for and a method of imparting temporary set to human hair involving the application of an aqueous composition containing a dialdehyde polysaccharide and a hydroxyaromatic compound in which two hydroxyl groups are meta to each other. After application of the composition, the tress is wrapped and heated using a conventional heated rod or brush type curling iron, heated roller, or salon or handheld hot air blower hair dryer to cause the polysaccharide and hydroxyaromatic compound to react with one another.

Abstract: This invention relates to bioerodible deodorant formulations for use on the human body employing the controlled release of water-soluble cationic germicides from hydrophobic carboxylic acid polymer matrices. A broad spectrum of germicide release rates is achieved by varying the choices of matrix and germicide and the loading levels.

Abstract: An erasable ink containing a thermoplastic block copolymer, pigment particles, and a solvent. In a preferred embodiment, an erasable ink requiring little or no pressurization is provided by employing a mixture of radial and linear block copolymers and a mixed solvent system falling within a specific range of solubility parameter. Polybutene and poly-alpha-methylstyrene are preferred additives to decrease smearing tendency.

Abstract: Shaving units as well as methods and apparatus for producing such units by using laser energy to weld a narrow elongated razor blade strip to a support member. In one form of the invention, a perforated welding mask made from a metal having high reflectance to the laser energy is employed to define the spacing of the welds joining the two members.

Abstract: Apparatus for testing internal pressure of a pressurized container having a ball partially extending outwardly from a ball seat includes a vise for holding the container in a fixed position and a force generating transducer arranged to provide a force proportional to the internal pressure for moving an end of a lever arm against the ball and statically holding the ball in a position substantially midway between first and second extremities of the ball seat.

Abstract: Reactive silicone hair setting compositions composed of isopropanol solutions containing at least one aminoalkylalkoxysilane and a titanate ester. Optional ingredients include hair conditioners and tetraalkoxysilanes. The compositions provide high set holding levels at high humidities.
