Abstract: A shock-absorbing golf-club head includes a front recess in the striking face of a golf-club head, extending to the top and the rear portion of the striking face and communicating with a rear recess by means of plural through holes. The front recess is mounted on with a metal face plate having circumferential dented edge to be fixedly engaged with the striking face synchronously when shock-absorbing material is formed into shape and affixed to both front and rear recess so as to form a double-deck shock-absorbing layer to acquire an effect of shock-absorbing, shock-lessening and stability of controlling golf balls.

Abstract: This invention relates to a dual curing silicone composition with an enhanced depth of cure. This composition incorporates an acylphosphine oxide or diacylphosphine oxide, the compatibility of which with the silicone is promoted through the use of a polar carrier. The composition may also include a second photoinitiator that is different than the acylphosphine oxide.

Abstract: A silicone sealant composition containing: (a) a moisture curable organopolysiloxane component, comprising a mixture or reaction product of (i) an organopolysiloxane polymer having hydrolyzable substituent groups and (ii) a polyfunctional silicon compound having two or more hydrolyzable substituent groups, (b) a filler and (c) a hydrocarbon fluid comprising, based on 100 parts by weight of the hydrocarbon fluid, greater than 40 parts by weight cyclic paraffinic hydrocarbons and less than 60 parts by weight noncyclic paraffinic hydrocarbons, exhibits improved tensile, elongation and adhesive properties.

Abstract: A low VOC primer composition suitable for use with room temperature vulcanizable silicones, comprising a polyorganosiloxane resin, an acrylic resin, an organotitanate, a silane or partial hydrolyzate thereof and an organic liquid in amount effective to dissolve the other components of the primer composition that provides improved adhesion to diverse substrates.

Abstract: A detergent dispenser with a window wiper includes a dispenser body, a connector fixed with an outer wall of the dispenser body, and a window wiper releasably fitted in the connector, to permit spraying a detergent and cleaning.

Abstract: Brushes held in a container includes a plurality of brushes, and a container storing the brushes in its interior. A spring for pushing up brushes to let one of them positioned in an upper end of the interior half pushed out of an outlet. Each brush has bristles is sealed in a housing, with their roots clamped firmly in a rear portion of the housing, which has a thin neck between a front portion and the rear portion. The neck is easily broken, letting the front portion removed to let the bristles expose out for use, with the container able to serve as a grip. After an uppermost brush in the container is used, the next one is pushed out of an outlet of the container to be used.

Abstract: A standardized test for measuring the stringiness of room temperature vulcanizable silicone sealant compositions is disclosed wherein a tube of sealant is held at a constant angle to the surface upon which the sealant is being applied. The surface is movable and once a small bead of sealant has been deposited upon the surface the surface is moved at a constant rate of speed until the sealant bead breaks off from the source. The length of any string of sealant formed thereby is measured. This measurement for a given composition is compared to the measurement for other compositions and thereby allows optimization of sealant compositions to minimize an undesirable feature.

Abstract: The present invention relates to acetoxy, ketoximo, and alkoxy silicone sealants suitable for use in various sealant applications and additionally food contact applications comprising di-iodomethyl-para-tolylsulfone and having physical properties improved thereby.

Abstract: The present invention provides an automatic pencil which includes a coil spring sleeved around an inner tube, and a ring-shaped head portion carrying a lead pushing leg, the ring-shaped head portion being seated on an annular shoulder formed in the lower cone-shaped end of an outer casing, and the lead pushing leg begins to extend downward from the ring-shaped head portion at a location beyond the inner edge of the annular shoulder, thereby eliminating the need to provide a groove for receiving the upper side of the lead pushing leg.

Abstract: An improvement in the mechanical pencil of the type shown in U.S. Pat. No. 4,320,982. The improved mechanical pencil has a tubular outer casing, a coil spring disposed within the outer casing and an inner tube slidably inserted through the outer casing and the coil spring, the inner tube being adapted to store therein a plurality of presharpened lead pieces and having a conical shaped head formed at its lower end, the conical head being provided with two slots to form into a pair of clamping halves for clamping and releasing the presharpened lead pieces. The coil spring, which is adapted to urge the inner tube upwards, has a lowermost coil provided with a straight tail extending from the lowermost coil inwardly and downwardly at a predetermined angle with the longitudinal center axis of the coil spring, to fit into one of the two slots of the conical shaped head of the inner tube, with the tip of the tail being arranged to abut the rear end of the lead piece clamped by the clamping halves.

Abstract: A novel comb is disclosed comprising a comb back, a comb-teeth module detachably mounted on the comb back, and a case member connected to one end of the comb back for serving as a handle. The comb-teeth module comprises at least one continuous wire wound helically into a plurality of coil-shaped comb tooth elements with each coil-shaped comb tooth element having an upper portion serving as supporting means to be fitted on the comb back and a narrowed and elongated lower portion for combing, wherein the narrowed and elongated lower portion of the comb-teeth module is capped with a removable cap member to normally assume a retracted condition having comb teeth compacted, and adapted to resume an extended condition having comb teeth spaced apart for use after the cap member being removed.

Abstract: A novel comb which comprises a comb back, a comb-teeth module detachably mounted on the comb back, and a case member connected to one end of the comb back for serving as a handle. The comb-teeth module comprises a continuous wire wound helically into a plurality of coils in juxtaposition with each coil including a V-shaped lower portion serving as a comb tooth and a rectangular upper portion to define a channel adapted to snugly receive the comb back therein. The comb-teeth module is provided with retainer means at both ends of the wire in order to be fixed on the comb back either in a retracted condition having the comb teeth compacted, or in an extended condition having the comb teeth spaced apart. The novel comb according to the present invention further comprises a plurality of spare comb-teeth modules arranged inside the case member, and a dispenser mechanism for delivering one of the spare modules to a position for use after the soiled module has been discarded.
