Abstract: A pocket clip stamped from metal strip material, fastened at its one end to the tubular part of a writing instrument and at its other end resiliently biased into contact with the tubular part, has at its fastening end two bent-back, tab-like material sections which reach through an opening into the interior of the tubular part. The tab-like material sections are curved at their free end portions situated inside of the tubular part, in a plane situated at right angles to the longitudinal central axis of the tubular part, with their concave sides facing one another, while their curved end portions engage with bias a locking component that is circular is cross section and is inserted from the open end into the tubular part. In an intermediate area still within the tubular part there is provided an open-ended slot in each of the tab-like material sections, enabling the curved end portions of the tab-like material sections to flex resiliently within the tubular part.

Abstract: A brush for applying makeup includes a multitude of bristles wedged into the spirals (9) of at least two branches (10, 11) of a helically twisted metal wire, which form the core (12) of the brush. Over at least a portion of the brush, bristles (8a, 8b) are provided the surface of which has at least one groove extending substantially from the base to the tip, and the cross sections of the bristles have different shapes, of at least two types. As a result, the bristles (8a, 8b) having different cross-sectional shapes are spaced apart differently with respect to the mid-plane (14) of the spiral, and there is a space (15) between the bristles to permit penetration of the eyelashes (16) or hair.

Abstract: A walk-behind turf aerating apparatus includes two pairs of tine arm assemblies, each assembly having a pair of vertically reciprocating tine arms for driving coring tines into the turf. A tine arm return mechanism includes a gear box for each pair of tine arms, the lower ends of the tine arms being connected to cranks extending from the gear box to reposition the tine arms prior to ground engagement. Stops are provided to limit the tine arm travel. A spring-loaded lifting mechanism permits manual shifting of the tine arm mechanism from a lowered ground-engaging position to a raised transport position. A belt drive with clutch and reduction drive for the wheels also drives the tine arm mechanism with automatic disengagement when the wheels are in the transport position. A handle assembly is connected to the apparatus frame through a pivotal connection including vibration damping elements for minimizing transmittal of vibrations, particularly in the vertical plane, to the handle.

Abstract: An improved soil leveling apparatus consisting of a scraper member with an edge and a plurality of ground engaging members with surfaces, the above connected by a pair of longitudinal side members, hitch structure attached, an optional lost motion linkage on the top portion of the hitch, an optional scarifier assembly, and a horizontal plate attached to the scraper member with vertical adjustment structure on the plate to change the scraper member from an edge to a flat surface and vice versa.

Abstract: Apparatus for deep plowing highly compacted soil includes successively forming troughs of loosened soil immediately adjacent a previously formed trough. After each pass the plow leaves a trough of loosened soil having a transverse vertical profile (called a "fracture profile") in the general shape of a parallelogram with sides inclined upwardly and toward the unplowed ground. Each successive trough is formed by pulling a first set of point plows located on the unplowed side of said successive swath and at a depth of approximately one-half the desired depth to loosen soil in the upper portion of the fracture profile. A second point plow located to the rear of the first plows and at the desired depth is pulled approximately midway of the bottom of the fracture profile to loosen the remaining soil in the lower portion of the fracture profile.

Abstract: A brushless white-out correcting fluid applicator for use in applying white-out fluid to paper without using a brush. The white-out fluid is a suspension including a substantial proportion of white or substantially white particles, such as titanium dioxide, or other color particles. The applicator includes a wear-resistant, porous tip and a regulator between the tip and a reservoir. The regulator may be formed of foam material, and the tip may be of sturdy porous plastic. The size of the pores in the tip and regulator are large enough so that they do not become clogged with particles in the white-out fluid. The regulator prevents the tip from dripping by regulating the rate at which fluid can leave the reservoir. The size of the pores adjacent the reservoir may be different than the size of the pores and passageways adjacent the tip. The applicator may be provided with an air-tight cap to avoid drying out between uses.

Abstract: A power operated hand guided device is designed to scarify, edge, and aerate lawns and grass.

A brake (37) which retards the forward movement by friction with the ground is connected to the motor assembly by a rod (38).

Abstract: A device for closing a curved duct, especially an ear protector for insertion in the auditory canal (4) of the ear, consists of an elastic rod-shaped body (1), e.g. of foamed plastic, which is pointed at one end and the cross-sectional area of which is larger than that of the auditory canal. The pointed end of the rod-shaped body is considerably offset with respect to the longitudinal direction of the body so as to form a lip (5) which is unsymmetrical in relation to the longitudinal direction of the body and capable of conforming to the curved portion of the auditory canal when the rod-shaped body is inserted therein.
