Abstract: The invention concerns a chuck device for use in medical, in particular in dental, straight and contra angle handpieces for accepting removable treatment tools by means of a clamping tab. The clamping tab is immovably connected by at least two points of contact with the casing of the chuck device. The spring effect and the clamping force for clamping the tool are generated and exercised exclusively by the clamping tab. Moreover, a method for manufacturing such a chuck device is described, by which means the complete chuck device may be manufactured on one machine only, exclusively by mechanical processing (machining), preferably by milling.

Abstract: An apparatus for transporting a band-shaped recording medium in an electrographic printing or copying device, includes a drive cylinder, a pressure cylinder mounted displaceably relative to the drive cylinder, and a pressure spring effecting a contact pressure of the pressure cylinder on the drive cylinder, wherein the recording medium is transported between the drive cylinder and the pressure cylinder by friction, and the drive cylinder adjoins the recording medium with a contact surface, and wherein the force effect of pressure spring is divided into a first, radial force component acting perpendicularly to the contact surface and a second force component received by a guide face guiding the pressure cylinder.

Abstract: A process and a device are described for detecting physical, chemical, biological or biochemical reactions and interactions on biochemically or chemically functionalized specimen carriers in the form of layers or films from the spectral reflection after irradiation of the specimens with light of different wavelengths. In so doing, parameters for the nature of the specimens are determined in an economical and highly accurate manner and with a high degree of parallelism in the measurements. According to the process, the specimens are arranged on a substrate plate with a carrier layer of a carrier plate and are irradiated with light.

Abstract: A surgical suturing instrument has an elongated housing forming a stationary jaw and a movable jaw formed with a holder for a suture filament and pivotal on the housing between a closed position closely juxtaposed with the stationary jaw and an open position spaced therefrom. A first actuating member displaceable in the housing is coupled to the movable jaw for moving it between its positions. A needle is movable in the housing between a position recessed in the housing and an extended position projecting crosswise from the housing to the movable jaw in the open position thereof. A second actuating member displaceable in the housing independently of the first actuating member is coupled to the needle for moving it between its positions.

Abstract: A display system for aircraft for showing the attitude, particularly the rolling and pitching position or the flight path angle, comprising a windshield projection device (HUD "HEAD-UP DISPLAY") with devices for generating and displaying an airplane symbol, a symbol which is stabilized fixed to earth for the displaying of the position of the true horizon as well as for generating and displaying symbols for the rolling and pitching angle or of the path angle in the exterior field of view of the pilot as a function of the values measured by the corresponding instruments. In this case, a display of the attitude is generated by means of a reference symbol representing the airplane and an information symbol which changes with respect to the reference symbol in its position and shape--and is dependent on the rolling angle (.phi.) and pitching angle (.theta.) or path angle (.gamma.).

Abstract: A method and device are provided to prepare a cutting tool such as used for die cutting sheet material, by mounting the cutting members in a mounting support with the method and device controlling the operational stages of the preparation. The device includes improvements in the press which are that a plurality of individual pressure elements are arranged on a support surface of a lower bed in rows and columns to form a rectangular configuration with each of the elements being individually controlled so that different groups of elements can be actuated to act on a pressing plate depending on the size of the cutting tool being prepared. To insure an accurate and equal pressure, the elements in each corner are actuated with a low pressure to bring the pressing plate and the tool being acted on into contact with the pressure surface of the upper bed and then high pressure is applied to the selected pressure element to insure the securing of the cuttings blades and members into a support of the cutting tool.
