Abstract: 1. Method of positioning and inspecting a patterned workpiece, e.g. a mask for manufacturing semiconductor elements, by means of a scanning beam generating different signals for the patterns and for the other workpiece surfaces, with a deflector system connected to a computer-monitored control circuit, and with an evaluator circuit for the signals scanned, characterized in that the scanning beam is moved over the region of a first edge of a selected pattern, and that the signal information obtained is stored, that the scanning beam is then moved over the region of a second edge of this pattern extending substantially in parallel to the first edge, and that the thus obtained signal information is thus stored, the region being respectively determined by a rectangular surface which covers the pattern material as well as the portion adjacent thereto, and whose long edges extend in parallel to the first and second edge of the pattern, the regions showing respectively the same dimensions, that subsequently, for evaluating the stored signal information produced by the scanning beam the signal information obtained during the scanning of the respective first region is inverted and subsequently integrated, and that the signal information obtained during the scanning of the second region is integrated without inversion, that the sum signal of the two integrals which is proportional to the deviation of the pattern edge from the central line of the scanning beam is applied to the input of the beam control circuit, the beam position being correspondingly corrected with respect to the pattern, that the workpiece with the measured first and second edges is moved into a predetermined inspecting position, and that subsequently the scanning beam is moved for testing over the entire pattern and optionally over further patterns on the workpiece.

Abstract: The invention contemplates a device for directly recording upon photographic film, such as 35-mm film, data such as time and/or other identification within the exposure frame to which the data is applied. In the described embodiment, the data form is digital, luminously provided by a plurality of LED devices (46), and a fiber optics bundle (28, 29) transmits each LED-generated digit display direct to the plane in which a pressure plate (20) engages the back surface (i.e., opposite the emulsion surface) of the film. The pressure plate (20) is resiliently suspended, for gently loaded contact with film at the exposure-frame region, and all LED components and their associated fiber-optics bundles are fixedly mounted to, and therefore resiliently suspended with, the pressure plate.

Title: Baler for forming cylindrical bales
Inventor: MCCLURE JOHN R
IPC: A01F15/07
Filed: 1981-03-27
Abstract: A roll forming crop baling machine (10) which forms the bale (42) by the use of rigid rollers (24, 26, 28, 30, 32, 34, 36, 38, 48, 50, 52, 54, 56, 58) and which nevertheless produces bales with a more even bale density. One set of stationary rollers (24, 48, 50, 52, 54, 56 and 58) and another set of shifting rollers (26, 28, 30, 32, 34, 36, 38) are used to form and compress the bale during a major portion of its growth. Each shifting roller gradually moves outward from an initial position near the core (40) of the forming bale which is radially inward from the stationary rollers, to a final position forming a continuous outer boundary with the stationary rollers

Abstract: There is provided a pressure-regulated, rotating percussion sprinkler. The sprinkler comprises a two-part housing (2, 4), a pressure-regulating, elastically stretchable diaphragm (20), dividing the interior of the two-part housing into a substantially peripheral inlet chamber (24), and a central outlet chamber (26). The inlet chamber is provided with an inlet connector (12). The underside of the diaphragm is accessible to the pressure prevailing in the inlet chamber. There is also provided at least one substantially tangentially oriented passageway (30) connecting the peripheral inlet chamber and the central outlet chamber, and an inverted cup-like rotor (32). The rotor comprises a hollow shaft (34) rotatably mounted in a first part (2) of the two-part housing, and a tubular projection (38) substantially aligned with the hollow shaft and extending inside the rotor. The cup-like rotor has a substantially annular peripheral wall, the inner surface of which is provided with at least one discontinuity (52, 53) constituted by a sudden and transient change of curvature and, in operation, serves as a race (54) for at least one spherical mass (56) freely movable in the space delimited by the diaphragm and by the inside of the cup-like rotor. The bore of the hollow shaft terminates on the outside of the two-part housing in at least one relatively narrow nozzle-like opening (49) producing a sprinkling jet. A flow of water introduced through the inlet connector enters the central outlet via the tangentially oriented passageways producing a vortex flow and exits the outlet chamber via the hollow shaft and the nozzle-like opening. The vortex flow entrains the spherical mass imparting to it an orbital movement upon and along the race, whereby, upon encountering, prior to being carried by its angular momentum over, the transient discontinuity, the spherical mass imparts an impulse-like, limited angular motion to the rotor, and, thereby, to the sprinkling jet.

Chacun des cristaux (21 et 22) possede une frequence de resonance relativement elevee et une frequence de resonance relativement basse. Un amplificateur (40) et un filtre de bande passante (50) sont connectes aux cristaux (21 et 22) pour former une boucle de reaction.

Abstract: An air heating (38) and outgoing air or waste gas conducting installation (32, 33) is proposed, using a heat source (2) for feeding an accumulator (15) which in turn covers a tap-water requirement or feeds a hot water central heating system (23). With a waste gas heat exchanger (32), the waste gas supplied from the heat source (2) is further cooled, this heat exchanger serving for heating the air in the region of the air heating. Downstream of this heat exchanger, a vent connection (37) is provided, with which outgoing air from any room can be conducted off and admixed to the waste gas. As this outgoing air has a lower moisture content than the waste gas downstream of the heat exchanger, a reduction in the humidity in the waste gas/outgoing air mixture is achieved. A waste gas/outgoing air blower is provided downstream of the waste gas/outgoing air combination point. Main area of application is the heating and ventilation of single and multiple dwellings. <IMAGE>

Abstract: Additional information is transmitted, in conjunction with message signals which are transmitted over a data switching center belonging to a public switched network. The data switching center is connected to teleprinter subscriber stations and teletex subscriber stations which are capable of transmitting and receiving message signals in accordance with different transmission procedures. The transmission of message signals between the subscriber stations occurs over at least one signal converter connected to the data switching center. After an occupation of the signal converter proceeding from a teleprinter subscriber station, the corresponding digital information are deposited in a memory of the signal converter by the data switching center upon each attempt to establish a connection from the signal converter to a teletex subscriber station. Under certain conditions, together with the message signal transmitted by the teleprinter subscriber station and contained in the signal converter, the additional information are emitted from the memory to the teletex subscriber station after a successful completion of a connection between the signal converter and the teletex subscriber station.
