Abstract: A double- or single-sided processing machine and a method for configuring a double- or single-sided processing machine are described. A first working disk and a counter-bearing element are driven rotationally relative to each other. A working gap for processing of flat workpieces is formed between the first working disk and the counter-bearing element. A control apparatus actuates step-by-step or continuous deformation of the first working disk between a concave shape and a convex shape. During the deformation, the working gap width at two or more radially spaced apart locations of the first working disk is measured. The control apparatus determines measurement value averages from the measurement values. The control apparatus determines the minimum of the measurement value averages and, using the determined minimum, specifies a target value for deforming the first working disk as a starting value for the processing of a flat workpiece.

Abstract: A rotor disk for guiding workpieces in a double-sided processing machine including a fluid feeding apparatus to feed a processing fluid into a working gap between a first working disk and a second working disk is provided. The rotor disk comprises a surface defining at least one workpiece opening configured to receive at least one workpiece to be processed on both sides in the double-sided processing machine in a material-removing manner using the processing fluid. A contact angle of a drop of the processing fluid with the surface is at least 60°.

Abstract: A method for casting a ring-shaped plastic frame comprises providing two mold parts, wherein at least one of the two molds parts includes at least one ring-shaped seat. Positioning a rotor disk between the two mold parts where the rotor disk comprises at least one annular recess. Engaging a mold core with at least a portion of each of the two mold parts. The mold core comprises at least one casting channel configured to attach at one end to a supply of plastified plastic. Inserting at least one mold insert into the at least one ring-shaped seat. A mold volume is defined by the at least one mold insert, the mold core and an edge of the at least one annular recess, wherein the mold volume is configured to fluidly connect with the at least one casting channel to receive plastified plastic to form a plastic frame.

Abstract: The shock-absorbing horseshoe comprises a rigid part for abutment with a hoof of a horse, said rigid part forming one rigid body with two backward facing branches. A lower section of each backward facing branch is shorter than an upper section, and a resilient part extends backward beyond rear edges of each said lower section and ends at rear edges of said upper section.

Abstract: The shock-absorbing horseshoe comprises a rigid part (1) for abutment with a hoof of a horse, said rigid part forming one rigid body with two backward facing branches (3,4). A lower section (9, 10) of each backward facing branch is shorter than an upper section (11, 12), and a resilient part (13, 14) extends backward beyond rear edges of each said lower section and ends at rear edges of said upper section.

Abstract: The device comprises a carrier for a workpiece; the carrier can be moved along a vertical and a horizontal axis by use of a drive mechanism and has an approximately planar contact surface for the workpiece, whereby the workpiece can be held on the contact surface by a contact mechanism of the carrier, especially vacuum, a retaining ring on the carrier encircling the contact surface and projecting downwards beyond the contact surface and having an inner diameter which is slightly larger than the outer diameter of the workpiece. At least three centering cams are arranged on a circle, the centering cams can be moved synchronously and in a radial direction by use of a centering drive, the centering cams having a supporting surface oriented on the top.

Abstract: In a horseshoe (1) having a resilient intermediate layer (4) positioned to fill out the interspace between a rigid upper and lower parts (2, 3), which are mechanically connected at the front edge of the horseshoe (1), the upper and lower parts (2,3) are, in addition, interconnected by an interlocking device (A: A1; A2) near at least one of the rear edges of the branches of the lower part (3) to prevent separation of the upper and lower parts, while allowing elastic deformation of the resilient intermediate layer (4).

Abstract: In a shock-absorbing horseshoe (1) a resilient intermediate layer (4) is positioned in a sandwich arrangement between an upper part (2) and an under part (3) substantially in parallel therewith, the intermediate layer (4) filing out completely the interspace between the upper part (2) and the under part (3). In the under part (3) openings (7A) are provided, said openings allowing passage of nailheads of conventional horseshoe fastening nails (13) in such a manner that the securing of the horseshoe (1) to the hoof by means of such nails is accomplished solely through the abutment of the nailhead against the resilient intermediate layer (4) and through the resilient compression of said layer.

Abstract: A cleaning cassette for cassette tape recorders comprises a cleaning member which engages the recording/reproducing head of the tape recorder upon placing the cassette in the recorder. Through a first and second transmission device the cleaning member is connected with an operative coil drive shaft in the tape recorder to impart to the cleaning member by the rotation of the coil drive shaft a reciprocating sweeping movement across the recording head. The first and second transmission devices each include a one-way coupling device connected with a common shaft pin carrying an eccentric head engaging a slot in a pivot arm whose free end is connected with the cleaning member. Each of the transmissions provides for a correct cleaning function irrespective of which of the two transmissions is connected with the operative coil drive shaft without establishing drive connection with the other transmission.
