Abstract: A laser scanner for optically scanning and measuring an environment comprises a light transmitter having a predetermined transmission power for emitting a light beam. The emitted light beam is reflected at a measurement point in the environment. The reflected light beam is received with a certain intensity by a receiver. The transmission power is adjustable as a function of the intensity of the reflected light beam. Furthermore, a gray-scale value of the measurement point is determined as a function of the transmission power adjusted.

A transmitter is provided in the measuring head for transmitting a light beam. A receiver is provided in the measuring head for receiving the light beam after a reflection thereof by an object located at a distance from the laser scanner.

Abstract: A method of automated preparation and characterization of liquid multicomponent systems comprising at least two, preferably three components comprises the automated preparation of a mixture by combining at least two, preferably three components in a vessel, at least one component being metered in an automated fashion into the vessel, and the automated homogenization of the mixture with subsequent automated measuring and evaluation. The apparatus for conducting this method comprises at least one metering station, one closing station, one homogenizing station, one measuring station for determining formulation properties, and one evaluation unit.

Abstract: A wheel suspension system for motor vehicles has a horizontally positioned spring-and-damper unit which, by way of levers and links, interacts with wheel carriers of opposite wheels. In order to design the wheel suspension system in a favorable manner with respect to space requirements while ensuring proper functioning of its components, a horizontally positioned spring-and-damper unit and a lever, which can be swivelled about an axis which is upright or relatively slightly inclined, are provided for each side of the wheel. The lever is applied by way of a first lever section to the spring-and-damper unit and is connected, by way of a second lever section as well as a first link to one of the wheel carriers. The lever is connected to a stabilizer by way of a third lever section as well as a second link.

Abstract: An adjustable suspension strut for a motor vehicle includes a damping element enveloped by a spring, a first ring cylinder axially slidable relative to the damping cylinder, a second ring cylinder disposed between the damping cylinder and the first ring cylinder, a working chamber defined by at least the first and second ring cylinders, and an adjusting element configured to adjust the relative position between the damping element and one of the first and the second ring cylinders. The second ring cylinder is axially slidable relative to the damping cylinder. The second end of the spring is disposed on one of the ring cylinders. The two ring cylinders are axially displaced relative to each other.

Abstract: Method and apparatus for determining and regulating the amount of advance of a plurality of workpiece plies at a sewing machine which is affected by scanning the individual plies while recording the stitches being formed between two separate feed points and actuating top and bottom feed devices to achieve a desirable feed of each ply. Signs present or to be applied at any desired point of the workpiece plies are scanned at two successive points, and pulses generated by a pulse generator connected with the main shaft of the machine are summed during this period of time. The pulse sum is compared with a number of pulses which depends on the mutual spacing of the scanning points and on the adjusted stitch length. For two work plies the pulse sums formed between the recognition of the signs are compared directly. As signs to be scanned are used either imprinted marks, the jags of a pinked workpiece edge, or the bright, dark structure of a surface section of the workpiece.

Abstract: A lubricating system for sewing machines is produced with the sewing machine running by cutting a predetermined amount of cotton fibers into small lengths and blowing the fiber lengths into the sewing machine housing. As the fibers fill the housing a felt cushion conformable to the paths of motion of the parts of the mechanism is produced. The felt cushion is supplied with oil through a wick.

Abstract: A brush mount on electric motors equipped with a radio-interference suppression choke (24), particularly for household appliances such as vacuum cleaners or the like, having a support part (7) of non-conductive material which is fastened in the motor frame (1) and into which a guide sleeve (13) of conductive material for the carbon brush (15) with its tensioning spring (17) is inserted by form lock in axially non-displaceable manner between two side walls (9, 10) extending from a web (8), the rear end of the guide sleeve (13) having a connection lug (50) for the conductor of the carbon brush (15).

Abstract: An industrial robot for gripping workpieces of diverse shape comprises at least one finger preferably two arranged for pivotal movement on respective sides of the workpiece. Each finger has at least one workpiece engagement member or joint which is movable thereon. Fluid pressure operated means are connected to the workpiece engagement member or joint so that it is moved outwardly from the associated finger to engage the workpiece and to be locked in the engaged position so that it will reengage in the same position after the finger is shifted relative to the workpiece to reengage it.

Abstract: The device is for use in a sewing unit including a sewing machine and includes a vertically oriented relatively elongated intermediate plate separating two plies of material in advance of the sewing machine. Guide elements adjacent the intermediate plate support a clasping station for movement longitudinally of the intermediate plate. The clasping station includes a support mounting two clasps each selectively engageable with a respective ply of material. Photoelectric sensing devices are movable with the clasping station, and include respective sensing devices operatively associated with each ply of material and each operable to control engagement of a respective clasp with the associated ply of material responsive to sensing of the trailing edge of the associated ply of material. A counterweight arrangement exerts an adjustable pull on the clasping station in a direction opposite to the feed direction of the plies of material.
