Abstract: A 3D object graphics display device for storing information about 3D objects such as works of art or buildings, and for displaying them on a 2D display. The "3D shape data" and "texture data" of a 3D object is stored in a memory in advance. When an operator operates a manipulator, a 2D image is generated, which would be acquired when the 3D object is seen from a viewpoint indicated by the manipulator, by using the 3D shape data and the texture data in every 1/60 sec or less interval (that is, a minimum display interval of the display device). The 2D image is shown on the display, giving the operator a virtual-reality-like feeling as if he was actually holding the 3D object.

Abstract: An apparatus for measuring the thickness of running sliver includes a body having inner walls defining a funnel-shaped cavity through which the sliver passes; a contact finger having an end portion for contacting the running sliver at the narrow end of the cavity; a support arrangement for movably securing the contact finger to the body; a device for urging the end portion of the contact finger into resilient contact with the running sliver for pressing the running sliver against a stationary component at the narrow end of the contact finger, whereby the contact finger performs excursions in response to thickness variations of the running sliver; and a transducer connected with the contact finger to transform displacements thereof into electrical signals. There is further provided an air stream generating arrangement for driving an air stream through the space which accommodates the contact finger, whereby the contact finger is exposed to the air stream.

Abstract: A method is described for detecting the time messages in the faulty signal of a time-signal transmitter comprising the steps below. Probabilities are assigned to the received information/bits as they are received and whose sign specifies the value of the bit and whose numerical value indicates the certainty of reception. Except for the bits designating the minute information, the probabilities of successive time messages are totaled with time correctness in a one-dimensional memory field. From the totaled probabilities, a reduced time message is reconstructed that initially contains no information on the minutes. If the reconstructed time message does not change over two successive time intervals, and if preset minimum values for the number of probabilities are exceeded for all bits, then the reduced time message is recognized as being correct. The minutes are determined separately and added to the time message recognized as being correct.

Abstract: An apparatus for severing a fiber bale tie surrounding a fiber bale includes a bale advancing device for moving the fiber bale in an advancing direction along a travel path; a tie cutter for severing the tie; a bale position determining device for emitting a signal when the bale has reached a predetermined location along the travel path; and a device for moving the tie cutter transversely to the conveying direction from a remote position spaced from the bale into engagement with a bale surface when the bale has reached the predetermined location to effect severance of the tie as relative movement between the bale and said tie cutter takes place.

Abstract: With a transistor ignition system, in order to generate an ion current measurement signal at the secondary end, the ignition transistor, following an ignition triggering impulse, will be driven such that a saw-toothed collector current results as a primary current, and whose rate of increase is selected such that the quasi-stationary direct voltage generated hereby at the secondary end will not trigger any ignition process. The advantage is that for generating such a measurement signal as well as for its evaluation only a few components are required.

Abstract: A ticket-printing device has a ribbon sensor and a mode-switching circuit. The mode-switching circuit automatically selects different printing conditions depending on whether or not the ribbon sensor detects the presence of an ink ribbon. The ink ribbon is wound on a supply spool and take-up spool. When the ink ribbon is replaced, a ribbon fixture holds the supply spool and take-up spool in correct relative positions so that they can be easily slipped onto a supply spool shaft and take-up spool shaft in the ticket-printing device.

Abstract: A helmet visor release apparatus has a pair of manually actuatable catches, each of the catches including a first portion to be disposed on a helmet; and a second portion to be disposed on a visor of the helmet. The first portion has an arrangement for releasably engaging the second portion, the arrangement for releasably engaging being manually actuatable for releasing the second portion from the first portion thereby releasing a corresponding one of the catches. The apparatus further includes a linkage mechanism connecting the catches to one another and being configured such that manual release of one of the catches causes a release of another one of the catches.

Abstract: A method for automatically coating objects with a spraying device which includes at least one atomizer that is moved along paths determined by programs. For respective objects or segments of objects, which essentially differ with respect to the dimensions, a program is provided which is modified as a function of the length of the respective object or segment, which length is allocated to a direction of a Cartesian coordinate system, for predetermining the path of the atomizer in the direction of the length of the object. By means of dimension data that are inserted into the program, the paths to be followed by the atomizer are constantly adapted along the predetermined path in at least one direction that extends at a right angle to this direction.

Abstract: An electromagnetic actuator operating a cylinder valve of an internal-combustion engine includes first and second spaced electromagnets having pole faces oriented toward one another; an armature arranged for reciprocating motion between the pole faces; and a connecting rod having a first rod part being in an abutting contact with a first side of the armature and being a component separate therefrom. The abutting contact is such as to prevent a torque transmission between the first rod part and the armature. The connecting rod has a second rod part which is rigidly affixed to a second side of the armature and extending towards the cylinder valve.

Abstract: A rain sensor in which an optical effective radiation (11) is subjected to at least one total reflection in a sheet of glass (16). The effective radiation (11) coupled out of the sheet of glass (16) into a coupling-out part (22) at the end of a measuring segment (24) and possibly present interference radiation (31') impact a separating surface (25) of the coupling out part, at which surface only one of the two radiations (11, 31') is totally reflected. The separating surface (25) permits a separation of the interference radiation (31') from the effective radiation (11) before it impacts a radiation-measuring device (30). The rain sensor of the invention is particularly suited for use in motor vehicles in connection with a windshield-wiping system which is operated automatically as a function of the rain sensor.

Abstract: In a device for fixing a ball screw/nut mechanism, including a ball screw and a ball nut, safe from turning. The ball screw/nut mechanism generates a linear movement to displace a first subassembly until it rests on a second subassembly. A blocking device is provided, which is adapted to fix the rotating part of the ball screw/nut mechanism, when both subassemblies are in contact, safe from turning through a reaction force originated by an external force and by overcoming the force of a first resetting means. When the parts are in contact, the blocking device is positioned in a determined distance from the first subassembly, and when the external force, generated by the drive device, arises the turnable part is safe from turning, until the determined distance between the first subassembly and the blocking device is compensated for.
