  • Patent number: 4691093
    Abstract: A novel multiple spot laser welding apparatus includes a bendable mirror capable of deformation, which receives a laser beam at a single reflective surface thereof. A deformation device deforms the single reflective surface of the bendable mirror to provide a plurality of laser sub-beams to a workpiece, generating laser spots on surfaces thereof. The apparatus can be used in a laser welding method that provides a common weld pool formed by laser spots transverse to the weld seam. Another laser welding method provides multiple laser spots oriented along a weld seam producing a common weld pool therebetween. Still another laser welding method provides multiple laser spots along a weld seam producing distinct weld pools.

  • Patent number: 4658982
    Abstract: A band carrying labels is transported step by step from a feed reel over a label removing station to a take-up reel. The drive mechanism consists of a double acting pneumatic cylinder pivotably connected to a frame, movement of the piston rod to effect trransport of the band is initiated by an optical scanner which senses the presence of a properly positioned box to which the label is to be applied. The return movement stopping the band transport is initiated by a band sensing device. The piston rod is coupled to the take-up reel by a rectangular linkage. The linkage causes the take-up reel to be moved with an angular velocity which increases during each transport step in such a way that the final linear velocity of the band at the end of each transport step is substantially independent of the diameter of the coil on the take-up reel.

  • Patent number: 4653990
    Abstract: In positive displacement pumps using double pistons for the alternating supply of pasteous material from two supply cylinders through a pivotable feed tube arranged in a feed chamber spaced at a radial distance from a controllably positionable shaft, the supply end of the feed tube is subjected to wear, which can impair the seal of the pump, and result in bleeding off of the pasteous material. In the inventive pump the supply conduit is connected to the pivotable feed tube through a pivotably arranged connecting member, through which adjustment of a sealing ring disposed in a rear wall of the feed chamber, and abutting a ring-shaped and also easily replaceable wear-resistant ring-shaped member is facilitated, while also permitting easy replacement of the sealing ring.

  • Patent number: 4650992
    Abstract: An optical sensor is made of light transmissive material and has luminescent particles distributed throughout its volume. The luminescent particles are excited by a suitable type of energy, preferably light. As they return to their original state, they emit light uniformly in all directions. Depending upon the relationship of the index of refraction of the sensor body material to that of a test medium abutting a boundary surface of the sensor body, part of the luminescent light is reflected, the remainder passing into the test medium with a change in direction (refraction). When the test medium is optically less dense than the sensor medium luminescent light incident on the boundary surface at an angle exceeding the critical angle undergoes total reflection. For an elongated sensor body, this totally reflected part is transmitted to the end faces of the sensor, where its intensity constitutes a desired measure of a physical quantity.

  • Patent number: 4577157
    Abstract: Apparatus is depicted which enables the sampling of the phase angle of a modulated signal and manipulates the sample signals to demodulate the same. The apparatus is particularly adaptable for use in demodulating the I and Q channel signals of a zero IF receiver. The system contains an angle sensing circuit which combines the I and Q channel signals in differential form to produce a series of output signals of an angular range indicative of the present value of the instanteous phase. The signals from the angle detector are coupled to an octant decoder which operates to determine the particular octant that the angle is to be included in. In the present system eight octants are used, each comprising 45.degree.. The octant decoder determines which octant the angle belongs in and assigns a predetermined angle value to that angle. In one embodiment, the assigned angle values are 0.degree., 45.degree., 90.degree., 135.degree., 180.degree., 225.degree., 270.degree. or 315.degree..

  • Patent number: 4575728
    Abstract: A vertical dipole array (2, 3 to 2.sup.(n), 3.sup.(n)) is formed on a substrate (1) using stripline techniques. The dipoles are supplied with RF energy from a feed system consisting of stripline conductors (4, 4', 5, 6, 7, 7', 9, 12). By a parasitic compensating radiator (11) provided opposite these conductors on the same side of the substrate, the influence of the conductors on the radiation pattern of the dipoles is largely compensated for.The conductors of the feed system are arranged so that a combination of a parallel feed and an equal line length series feed (or, if the radiation pattern is to be raised, a series feed with suitably chosen line lengths) is obtained.

  • Patent number: 4573167
    Abstract: To convert an input-word sequence into a digital line code of half the bit rate of the input-word sequence, particularly for digital color television signal transmission, an encoder is disclosed which has a difference branch in which the difference (D.sub.i) between every two successive input words (X.sub.i-1, X.sub.i) is converted into a difference code word (D.sub.i) by adaptive PCM quantization, and a sum branch in which the sum (S.sub.i) of the same successive input words (X.sub.i-1, X.sub.i) is converted into a difference code word (S.sub.i +P.sub.i) in a hybrid DPCM encoder. These two words are combined into a line code word (C.sub.i) by an adder (9). The quantizing characteristic of the adaptive PCM quantizer (1) is selected as a function of the prediction error present within the hybrid DPCM encoder (2). The decoder at the receiver of the novel communication system splits up the received line code word (C.sub.i) into the difference code word (D.sub.i) and the sum code word (S.sub.i +P.sub.
