  • Patent number: PP9502
    Abstract: A new and distinct Chrysanthemum cultivar named `Chalurido` is provided. The new cultivar is a mutation of the `Chalecat` cultivar (U.S. Plant patent application Ser. No. 08/273,998, filed Jul. 12, 1994). Attractive large double incurved blossoms of the pompon type are formed that are Venetian violet on the inner ray floret surfaces and silvery lavender on the outer ray floret surfaces. The blossoms are long lasting and commonly keep their form for approximately three weeks on the plant and more than four weeks in a vase. The response period of the flowers is approximately nine weeks. Recurrent profuse flower production throughout the year is possible. The plant possesses strong thin stems, forms dark green glossy leaves, and commonly assumes a height of approximately 45 to 50 cm. The new cultivar is particularly suited for use in the production of a decorative pot Chrysanthemum that grows well single stem or disbudded. No growth regulator is necessary to achieve the short to medium plant height.

  • Patent number: RE35202
    Abstract: The invention is directed to a new method for the production of a starch raw material for subsequently obtaining pure starch from wheat, rye, corn or barley. Fractions of starch which is damaged as little as possible are produced by means of roller grinding and sifting devices. The material is ground repeatedly and sifted with the system of advanced milling, wherein it is suggested in particular to guide the material two to five times via double-grinding stages without sifting between the double grindings. Sifting is effected subsequent to the double grinding. The invention also concerns a starch milling system which comprises two to five double-grinding passes with two grinding-roll pairs which are connected one after the other and are preferably constructed as an eight-roll mill.

  • Patent number: RE35203
    Abstract: An array of electron beam tubes is mounted on a conductive plate for projecting strip-like electron beams through air onto a substrate beneath the plate. The tubes each have a narrow beam window formed by a very thin low-Z film layer, supported by silicon and sealing the tube against ambient pressure. Such windows produce low beam attenuation and allow low extraction voltages to be used, thereby reducing beam energy which would otherwise be lost by penetration through a surface to be treated. The stripe-like output electron beam segments may be formed into a linear beam track so that the entire widthwise extent of a surface, such as a sheet or web, may be treated by electron beam irradiation or the beam segments may be formed into any desired composite beam pattern. In another embodiment the stripe-like output beam segments may be arranged in an array to treat a circular circumferential surface, such as a cable.

  • Patent number: RE35205
    Abstract: A magnetic tape drive has firmware which has been modified so that the drive will read both standard formal tapes and non-standard format tapes. Non-standard tapes are detected by an absence of reference bursts in the load zone of the tape. The head is moved to successive tracks toward the edge of the tape until no data is read. This identifies the track near the edge of the tape. Then, the head is preset to a track which is a known distance from the edge of the tape. Reading of non-standard tapes is accomplished by disabling the index pulse generator in the intervals between data segments. The performance of a SKIP COMMAND is made possible by counting the transitions of data to no data during the intervals between data segments. The identification of different types of non-standard formats is made by determining the length of the data segments.

  • Bib
    Patent number: 5504941
    Abstract: An easy-to-clean bib comprises a body, preferably made of a durable, flexible and non-porous material, and has a front and a back. The material is easy to clean and does not allow liquid to leak through as opposed to some bibs that are made of paper, plastic or similar light materials. The body includes two upper sections for placement on opposite sides of a user's neck. The upper sections include cooperative fasteners that fasten the upper sections together and thereby cause a portion of the bib body to bow outwardly in order to conform to the user's chest to help prevent particles and liquid from falling under the bib and onto the user. The bib body further includes a lower section for forming a temporary pouch. The pouch is formed by folding each of two lower comer portions up towards the front of the body and fastening a bottom piece of a cooperative fastener to its corresponding top piece and then fastening a bottom piece of a second cooperative fastener to its corresponding top piece.
