Abstract: The method and apparatus provide for transversely separating and laterally trimming or finishing continuously passing strips in processing lines for strip material, such as metallic strip. The strip is first severed in transverse direction and immediately thereafter is trimmed at the sides thereof. The time required for adjusting the lateral shears is approximately equal to that of the coil exchange operation leading to the time gained, and stoppages of strip in the operating stages are precluded.

Abstract: One or more sensors are used for the indication and/or control and/or adjustment of filter devices and/or ventilation systems in relation with a measured value or respective measured values, established by the sensor, or respective sensors. In order to provide an economically simple and maintainance free device of the afore-mentioned kind with reduced space requirements, which responds to all common air pollutants and insures a reliable reading, the invention proposes that the sensor be placed in a housing with a side facing the oncoming flow preceded within the housing by a measuring slot abutting an air chamber of the housing, where a pulsator is located, whereby one or more air-inlet openings lead to the cylinder space of the air chamber facing away from the sensor. The pulsator consists of a piston coupled with an oscillator. In the air chamber an air-conditioning device, preferably a heating device, is provided.

Abstract: An a manipulator having a pair of main elements pivoted together at a main axis has a drive having a motor mounted on one of the elements and having a motor output, and first, second, and third stepdown transmissions connecting this output with continuous-mesh force transmission to the other element. The first stepdown transmission has an input wheel connected to the motor output, an output wheel, and a toothed belt interconnecting the input and output wheels. The second stepdown transmission has a rotary input element connected to the output wheel, and a rotary output element noncoaxially associated with the input element and connected thereto. The third stepdown transmission has an output gear connected to the other element centered on the main axis, and an input gear rotatable about a gear axis offset from the main axis and having two axially separate halves relatively rotatable about the gear axis and both meshing with the output gear.

Abstract: A method of making a dental prosthesis in which data representing standard tooth shapes and sizes, relationships between teeth and adjacent and occlusive teeth and characteristics for securing a prosthesis to a prepared site, and machining instructions for shaping a blank to the configuration of a dental prosthesis for direct implantation are stored in a computer memory. After preparing a site in the mouth of a patient to receive a dental prosthesis, the dental surgeon projects optically a grating upon said site in the mouth of the patient and generates an interference pattern representing a holistic impression of said site and its relationship to adjacent structures. The interference pattern is converted into data along x,y,z coordinates in a cartesian coordinate system representing machining of a blank to fit said site and matching data obtained by comparing the impression with the computer standards are used to select a best-fit shape and size.

Abstract: In the process for reducing the noxious substance contents of flue gas, particularly flue gas desulphuration by dry process, the adsorber (1) and/or the regenerator (2) are built like a shaft. Active coke is introduced in the shaft in plane heaps with free intervals between each other: the coke is transported batchwise from top to bottom and is traversed by the flue gas. The heaps are supported by grates (6) of which the bars may come out at least partially from the grate plane so as to disintegrate the heaps and to bring them to the following stage in the form of a trickling flow, so that a constant thickness with respect to the cross-section is maintained. The infeed and evacuation of the flue gas with shaft-like absorber (1), respectively the gas streams in a shaft-like regenerator (2) are carried out in such a way that at least a preponderant number of heaps is traversed from bottom to top. Optionally it is possible to provide in the adsorber a mixture with NH.sub.3 gas in order to denitrify the flue gas.

Abstract: A last has an insert shaped to fit within a shoe during its manufacture and a stem fixed on the insert, projecting along an axis from the insert, and formed with radially oppositely projecting front and rear protrusions. A gripper has front and rear jaws formed with respective recesses complementarily engageable with the protrusions so it can accurately hold and position the shoe and last. The protrusions and recesses are formed substantially entirely of planar surfaces, although they can be complementarily rounded, for instance part-spherical. The stem has a radially directed flat provided with indicia and the gripper is provided with a scanner juxtaposable with the flat for reading the indicia. A stationary card on the flat carries the indicia.

Abstract: An optical beam is injected into a single-mode fiber of a given length and outgoes from an end face of the fiber, is reflected by a reflecting optical system into the fiber; the optical power of the reflected beam guided backward by the fiber is measured. The end face of the fiber is placed in the optical center of the reflecting system to obtain the maximum reflected power, and is then deviated from the position detecting the occurring reductions of the reflected optical power.

Abstract: The process for replacing an empty roving bobbin with a full roving bobbin in a spinning machine, particularly in a ring spinning machine, in a dispensing position by an automatic roving bobbin changing device comprises taking the full roving bobbin from a storage location and putting the full roving bobbin in place of the empty roving bobbin. The full roving bobbin associated with the dispensing position is taken from one of a plurality of stand-by positions in the storage location. To provide a more automatic operation the process further comprises testing whether the full roving bobbin is present in one of the stand-by positions adjacent the dispensing position before beginning the exchange and when the absence of the full roving bobbin is indicated inducing a relative motion between the roving bobbin changing device and the stand-by positions until the roving bobbin changing device stands adjacent to one of the stand-by positions having a full roving bobbin.

Abstract: In the process according to our invention authenticating (code) marks are provided on paper, particularly a security or other financial instrument, by contacting laser radiation from a laser light source on the paper to form the authenticating marks. The objects of our invention are attained with an apparatus equipped with a pivotable mirror device which allows the laser radiation to be directed on sheets of paper arranged transverse to the transport direction on a paper sheet. A preservative medium can be used to coat and protect the marks particularly from mechanical abrasion.
