Abstract: A device (1, 1?, 1?) for covering a golf hole (2) is provided, that has a planar top side (3) and is or can be arranged inside said golf hole (2) and is designed to cover or close the golf hole (2) reversibly. This device (1, 1?, 1?) is designed and intended such that the planar top side (3) of the device (1, 1?, 1?) is aligned approximately flush with a top edge (4) of the golf hole (2).

Abstract: A positioning device for a golfer when putting has orientation means for orienting the positioning device relative to a target, placement means for predetermining a relative position of the positioning device and a golf ball, and adjustable positioning means for predetermining a standing position of the golfer relative to the positioning device, i.e. relative to the golf ball. The position of the golfer's feet with regard to the golf ball can be reproducibly predetermined or adapted, respectively, using the positioning device.

Abstract: A putter fitting device (1) having a base plate (2) with a fixation device (5) for a putter head (14), which provides a first fixation state for a first, torque-proof fixation of the putter head (14) and a second fixation state for a second, rotational fixation of the putter head (14) in reference to the base plate (2), with the putter head (14) in the second fixation state being rotational in a plate plane of the base plate (2). An adjustable positioning body (11) is connected to the base plate to predetermine a stance of a person in reference to the base plate (2), and alignment markings (9, 27, 29) are provided for a targeted alignment of the putter head (14) in the second fixation state and for controlling a selected alignment of the putter head (14).

Abstract: A device to practice playing golf having at least one first, flat section for placing the device onto the ground, particularly in the area of the green of a golf course, and a second section, at least arranged partially off-set in reference to the first section so that after the placement of the device with its first section a golf ball can be located underneath the second section. The device is provided with an arrangement in the second section, by which a marking applied on the golf ball is discernible in order to check the relative alignment of the device and the golf ball. This allows a golf ball to be aligned to a target and/or a target alignment of the golf ball that is set can be checked.

Abstract: A contact pin for pressing into a through-connected hole of a printed circuit board is produced by forming. Its press-in portion has two contact legs spaced apart from one another by an elongate opening, are outwardly curved in their central region and, when pressed into the circuit board come to rest with plastic deformation on the wall of the hole. A portion for introduction into the hole includes at least two elongate portions resting on one another during introduction. These portions, after forming and before introduction into the hole adjoin the outwardly open elongate opening like fork prongs. As a formation projects into the opening at an edge thereof to form support regions which, after introduction of the contact pin into the hole, are located inside the hole, a contact pin and a method for the production thereof are provided, by punching in conformity with standards, with optimum extraction forces.

Abstract: A cylindrical pin (1) for connecting and/or guiding components (A, B), particularly in tool, fixture, and machine construction is provided. In order to make the cylindrical pin yieldable in a radial direction and thereby allow for compensation for its manufacturing tolerance, the cylindrical pin is provided with an internal bore (4, 6) extending in the axial direction at least over a partial region (1a, 1c) of the pin.

Abstract: A contact fastened in a contact element by opposite overlaps is provided. The contact is subsequently connected to the contact element with a laser or a special stamping.

Abstract: A method of production and/or processing of contact elements for electrical plug connectors is provided. The contact elements are fixed to a transport strip during the production and/or processing process. This transport strip is reduced in its material thickness after at least a portion of the production and/or processing process by deformation between the fixed positions of adjacent contact elements on the strip, so that the spacing between the fixed positions of adjacent contact elements is increased.

Abstract: A guide for machine tools and the like is proposed that includes a guide column and a parallel installed tenon joint, wherein the tenon joint itself is formed from parts of the guide column and/or a guide sleeve, and the parts of the guide column and/or guide sleeve that form the tenon joint are located axially offset from or coaxial to the bearing of the guide column in the guide sleeve.

Abstract: To permit punching of very small holes from a strip of sheet metal, for example to form a sequence of holes at the margin thereof, or to obtain small punched blanks, having diameters of a few millimeters, for example 1-2 mm or even less, and prevent adhesion of the punched blanks to a reciprocating punch plunger (1), the punch die (4) is formed with a shallow groove (8) in the wall of the opening (5) of a die, the groove extending either spirally or axially for the depth of penetration or stroke of the punch plunger. Upon withdrawal of the plunger, a small projection or nose which will have formed in the region of the groove will wedge or jam therein, thus preventing upward travel of the blank with the withdrawing reciprocating tool. Preferably, the opening is slightly conical, with a cone angle of, for example, about 1/2.degree. with respect to the axis (12) of the bore (5); a suitable angle of inclination for a spiral groove is, for example, 12.degree.
