Abstract: The invention relates to a method for measuring the visual field of a person by means of a device, comprising the following steps: displaying a visually detectable test spot on a surface display of the device, which surface display is viewed by the person by means of an eye of the person, wherein a spatial position of the head of the person remains unchanged with respect to the surface display; moving the test spot on the surface display by means of the device along a path during a measurement pass and activating an interaction means of the device by the person if the displayed test spot stops being visible or becomes visible again to the person at a current position during the movement of the test spot along the path, wherein, by activating the interaction means, the device is prompted to store the particular current position and any associated information from which it can be derived whether the test spot has stopped being visible or has become visible again for the person at the current position; and displ

Abstract: Sub-diffraction limited magneto-optical microscopy, such as Kerr or Faraday effect microscopy, provide many advantages to fields of science and technology for measuring, or imaging, the magnetization structures and magnetization domains of materials. Disclosed is a method and system for performing sub-diffraction limited magneto-optic microscopy. The method includes positioning a microlens or microlens layer relative to a surface of a sample to image the surface of the sample, forming a photonic nanojet to probe the surface of the sample, and receiving light reflected by the surface of the sample or transmitted through the sample at an imaging sensor. The methods and associated systems and devices enable sub-diffraction limited imaging of magnetic domains at resolutions 2 to 8 times the classical diffraction limit.

Abstract: In order to dry and cure a coating based on a water dilutable system, heat is supplied to the coating using an infrared radiator (1). In order to accelerate evaporation of the water, an air flow aligned perpendicularly to the infrared radiation is produced between the article on which the coating is applied, and the infrared radiator (1), using a fan (2). The power of the infrared radiator (1) and/or that of blower (2) can be changed in the course of drying and curing.

Abstract: A car headlight lamp having a lamp envelope (1), which is closed by seals (2) through which current lead-in members (3,4) are passed and is secured by a holding member to a socket (17), the holding member having a dipping cap (12), which at least partly surrounds the lamp envelope and is connected to a current lead-in member (4) of the lamp envelope. The socket (17) has an outwardly projecting cylindrical flange bush (24) for receiving the lamp envelope (1) and the lamp envelope has a tubular prolongation (6), onto which a clamping sleeve (7) is slipped, which consists of a cylindrical sleeve body (8), which has an outer flange (9) secured to the flange bush and several inwardly directed resilient tongues (10), which bear on the prolongation of the envelope. The dipping cap (12) is secured to the clamping sleeve (7).

Abstract: The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements.

Abstract: An apparatus for performing lamellar refractive corneal surgery includes a base ring adapted for seating on the sclera of the eye to be operated upon. A planar plate is fixedly attached to this base ring so that the mutually adjacent surfaces of the plate and the base ring conjointly define an air gap. As oscillating knife is guided in this air gap during the cutting process and is moved in a guide connected to the base ring. The surface of the planar plate facing the eye contains an applanate surface which is preferably defined by the end face of an insert inserted into the planar plate. A ring-shaped recess open toward the eye concentrically surrounds the insert and communicates with a conduit to which a partial vacuum can be applied.

Abstract: To permit resharpening of cutter blades of a helical milling cutter, the cutter blades or bits of a multi-bit cutter have decreasing thickness, and are placed in grooves having the same helix radius, but the centers of the helical axes offset from the center of rotation of the cylindrical cutter body in the direction towards the associated groove, so that cutter blades of lesser thickness are still seated firmly in the bottom of the respective groove. Upon dulling of the cutters, the thinnest one of the cutter blades is discarded, the thickest one only replaced and the worn blades moved up one step along the circumference of the body into grooves which are progressively more shallow, to compensate for decrease in thickness of the respective cutter bits upon regrinding to resharpen the bits.

Abstract: A partial lining disk brake with floating saddle for vehicles, particularly for motor vehicles, in which the floating saddle is constituted by an essentially plane frame that is arranged with its longitudinal webs secant-like with respect to the brake disk and which receives in one longitudinal web at least one brake cylinder and in another longitudinal web at least one abutment for the brake lining; the floating saddle is displaceably guided at the brake carrier axially parallel to the brake disk whereby the brake carrier is also constructed frame-like and, insofar as it has any supporting function, is arranged exclusively underneath the floating saddle, the floating saddle engages with downwardly extending projections in corresponding guide elements of the brake carrier to assure an accurate guidance thereof.

Abstract: A partial lining disk brake, especially for motor vehicles, with a U-shaped brake housing externally surrounding the brake disk and with hydraulically actuated brake cushions arranged on each side of the brake disk which are axially displaceably supported at guide members, preferably with the aid of their lining carriers; each brake cushion is thereby supported at two guide members which are arranged in the center plane of the brake cushion extending through the brake disk axis, whereby one guide member engages with the brake cushion from the outside as viewed in the radial direction while the other engages with the brake cushion from the inside.
