Abstract: An electric shaver is arranged to alleviate a cause of psuedofolliculitis by cutting low-lying facial hairs to a predetermined length. The electric shaver comprises a movable cutter and a perforated shaving foil having ribs protruding from a surface normally placed in contact with a user's beard. The shaving foil is arranged to move simultaneously with the cutter so that the ribs might lift and direct low-lying facial hairs through the perforations in the foil for shearing by the moving cutter.

Abstract: This invention concerns a foil for electrically or mechanically operated dry shavers.More especially the invention concerns a foil made from a sheet having perforations and bars between the perforations, the bars being dished in cross-sectional profile, the base of the dished profile being flat and of uniform thickness (t) while the edges extend at an obtuse angle .alpha. to the base, terminating in coplanar faces parallel to the base, the width of the face (w) being not greater than the thickness (t).The foils are especially suitable for battery operated razors, in which the reduced thickness (t) leads to reduced power consumption and longer battery life.

Abstract: A dry shaver foil head comprising a frame having arcuate support surfaces at opposite ends, and a part-cylindrical foil having opposite arcuate end portions respectively seated on said arcuate support surfaces. One longitudinal edge portion of the foil is attached to the frame by hooks, on the reinforced foil edge portion, hooked over a rigid rod also serving as the hinge pin which hinges the shaver head to a shaver body. The other longitudinal edge portion of the foil is attached to the frame by hooks, on the reinforced foil edge portion, hooked over a resilient rod at points spaced from points where the resilient rod is held by the frame. The resilient rod is thereby resiliently curved to maintain the foil in a state of significant tension to seat the foil on the frame in a substantially rigid part-cylindrical shape.

The drive means includes a part-spherical driver head articulated to said inner cutter at a center of articulation substantially coincident with the center of gravity of said inner cutter and the center of application of the resultant of the frictional forces acting between said inner cutter and said foil during reciprocation of said inner cutter by said drive means is substantially coincident with said center of articulation and with said center of gravity.

Abstract: A dispenser and a shaving unit, the shaving unit having a slide coupling thereon for attachment to a razor handle, the dispenser comprising a base portion, and an elongated tongue extending outwardly from the base portion, the tongue being adapted to releasably retain the shaving unit thereon by frictional engagement of the tongue with the slide coupling of the shaving unit.

Abstract: The present invention is concerned with processes for microhoning cutting edges and especially those of razor blades, wherein the edges are subjected to sonic energy and especially ultrasonic energy while said edges are in contact with a slurry or dispersion of abrasive particles which have diameters of less than 3 microns.

Abstract: The present invention is concerned with processes for michrohoning cutting edges and especially those of razor blades, wherein the edges are subjected to sonic energy and especially ultrasonic energy while said edges are in contact with a slurry or dispersion of abrasive particles which have diameters of less than 3 microns. The sonic or ultrasonic energy is emitted from a horn having a corrugated end and the ridges of said corrugated end are oriented so as to be perpendicular to the edges of the razor blades as they pass the horn, said blades being stacked in a magazine in which their edges are substantially parallel to one another and their flat surfaces in face-to-face relationship.

Abstract: An adapter for injector razors comprising a substantially rigid one-piece tool insertable in the head of an injector-type razor and operable to open the head of the razor such that a used blade therein may be released and a new blade manually inserted.

Abstract: A ball holder for a ball-point pen is arranged to have a ball socket with a ball seat having a plurality of convex surfaces formed on concave shoulder surfaces. A writing ball inserted in the ball socket is supported by a single ball contact point on each of the ball seat convex surfaces. Concavities are provided between adjacent convex surfaces and shoulder surfaces for collecting and supplying ink to a surface of the writing ball.

Abstract: An electric dry shaver in the form of a generally rectangular parallelepiped and comprising a flexible part-cylindrical curved cutting foil extending along one end face and inclined towards the front face of said parallelepiped. A cutter body has cutter blades having curved cutting edges and extending in planes perpendicular to the foil cylinder axis. A spring acts on said cutter body to urge said cutting edges into engagement with said foil. A rotary electric drive motor has its axis of rotation extending between said opposite end faces. A cutter support member carries said cutter body and is mounted to a shaver body member by a pair of spaced parallel leaf springs, each said leaf spring lying when unflexed in a plane parallel to said opposite side faces. The electric motor has a rotary output member adapted to drive said cutter support member in generally longitudinal oscillation with flexing of said leaf springs.

Abstract: An electric dry shaver comprising a cutter mounted for arcuate oscillation about an axis to effect a shaving action, a driver secured to said cutter for arcuate oscillation about said axis, a trimmer element mounted for linear reciprocation parallel to said cutter axis to effect a hair trimming action, and a coupling mechanism selectively engageable between said driver and said trimmer element to convert arcuate driver oscillation into linear trimmer reciprocation via the intermediary of a cranked lever mounted for pivotal oscillation about an axis perpendicular to both the cutter axis and the trimmer element.

Abstract: Aqueous depilatory compositions are made by complexing 0.2 to 0.8 Sn(II) with a polyhydroxycarboxylate anion having five to seven carbon atoms and four to six hydroxyl groups in a molar ratio from 2:1 to 1:2 at a pH from 12.8 to 13.3.

Abstract: A hair clipper is arranged to alleviate one cause of pseudofolliculitis. The hair clipper comprises a motor for reciprocally moving a first cutter against low-lying facial hairs causing these hairs to become erect for cutting above the skin line between the moving first cutter and a stationary second cutter.

Abstract: The invention concerns a method for producing foils for dry shavers.The method of the invention includes forming a layer of photosensitive material on each side of a metal plate, exposing each side to light to produce a pattern of exposed and unexposed areas, corresponding to perforations at one side and recesses in the backs of the bars of the foil on the other side, etching each side, them removing photosensitive material from the front side and carrying out further etching until the foil is completely perforated.The invention is especially suitable for forming foils for battery operated dry shavers.

Abstract: The present invention is concerned with incorporating bis-(chloroalkyl) vinyl phosphonates in polyfluorocarbon coatings to improve the adhesion of such polyfluorocarbon coatings to cutting edges and especially to razor blade cutting edges, said cutting edges having outer surfaces of alumina, silica, tungsten, titanium, or tantalum.

Abstract: A portable electric curling iron has a hollow handle having an open end. An electrically heated hair curling member is arranged for telescopic movement between a retracted storage position within the handle and an extended use position wherein the member projects from the handle through the open end thereof. Movable electrical connector plug means are provided on the iron for connecting the electric heating means associated with the hair curling member to a power source. Means are provided for automatically moving the connector plug means between a retracted plug position wherein the plug means is substantially entirely within the handle and an extended plug position wherein the plug projects from the handle in response to the telescopic movement of the hair curling member into and out of the handle.

Abstract: An electrical heater assembly comprising a heat generating element and a temperature regulating device supported by a heat conducting core of electrically insulating material is constructed to provide a thermal path for conducting heat from the heat generating means to the temperature regulating device with minimum thermal resistance, whereby temperature fluctuation is minimized.
