Abstract: A method for preventing damage to the strand guide elements of strand guide arrangements or roller aprons of a continuous casting installation for metals, especially steel, wherein it is possible to withdraw a strand which is immobile in the strand guide arrangement or roller apron, by means of a powerful withdrawal unit, without the risk of damaging elements of the strand guide arrangement. At pre-selected locations of the strand guide arrangement there are determined the withdrawal forces effective at such locations and acting upon the elements of the strand guide arrangement. Upon exceeding maximum permissible values the strand withdrawal operation is interrupted.

Abstract: The invention relates to a thermoplastic propylene block copolymer comprising one or more substantially crystalline polypropylene blocks and one or more 1-alkene-propylene copolymer blocks, in at least one of which 1-alkene-propylene copolymer blocks diene units are present, and to a process for preparing such a propylene block copolymer. According to the invention, as diene, a cyclic hydrocarbon compound is used wherein at least one double bond forms part of a strained structure, particularly a polycyclic compound with 7 to 20 carbon atoms containing at least one 4- and/or 5-ring, with one or more double bonds in or to the ring. The invention offers the advantage that it is possible to prepare block copolymers which can otherwise not or hardly be made, while at the same time only a small quantity is formed of byproducts which are soluble in the dispersant.

Abstract: A sliding gate valve assembly employed on the side of a furnace as a furnace valve is so structured that the shut off of metal flow from the furnace occurs by directing the slide gate (21) to the up position rather than the down position. In addition, to facilitate a reduction in space at the slide gate, the slide gate is desirably configured to be asymmetrical, with the short end extending upwardly from the pour opening (29) in the nozzle. A refractory lined heat shield (26) protects the sliding gate carrier (22) and also serves to mount a collector extension (30) when used. The slide gate (21) is provided with a metallic frame (60) which retains a monolithic refractory (80) into which erosion resistant refractory inserts or performed members (29,70) are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Similarly in the stationary plate (20), means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts in the manufacture of the stationary plate. The stationary plate is symmetrical to provide full travel pressure face relationship with the sliding gate (21). Both the stationary plate (20) and slide gate (21) casting have spring pad back up reinforcements. The statutory plate desirably has means for securing a well nozzle (19) to it.

Abstract: An arrangement for transmission of television composite signals contains coders which convert luminance component Y, and chrominance difference components U, and V of a television signal into variable-length code words. These are interlaced in a multiplexer in pulse frames by assignment to fixed locations. At a receive side, a time-division multiplex signal formed is in turn separated in a demultiplexer. Decoders reconvert the variable-length code words into the Y, U, and V components. The luminance and chrominance components can be reliably separated at the receive side due to the assigning of fixed locations in the pulse frame, these components being reliable separated even when the word synchronization of the individual components is lost.

Abstract: A method for providing National Language Support (NLS) in networking products as well as a network computer system is described which optimizes user-friendliness for end users by presenting them with a single-system-image view of the network, optimizes user-friendliness for installations by preserving their independence from other installations with respect to language support, and minimizes the amount of data that must be transmitted through the network to communicate messages and screens to users at remote sites. The invention provides for the coexistence of different product releases, including pre-NLS releases, in the same network and for the addition of screens or messages between releases through service or installation modification. In addition, it provides a language-independent message interface between a vendor product and user-written applications. The applicability of the method is limited only by the vendor's imagination.

Abstract: The present invention provides surgical gowns and other garments possessing the advantages of raglan sleeve construction in terms of comfort and freedom of movement, with improved manufacturing efficiency. The garment (100) of the present invention provides a raglan sleeve divided into an upper portion (20) and lower portion (30) joined approximately in the area of the bicep. Waste is greatly reduced by creating a shoulder portion from material removed to form the arm openings in the body portion of the garment. The shoulder portion (20) is attached to the body portion of the garment to form a raglan shoulder portion which extends to about the bicep of the wearer. A sheet of material is cut in a trapezoidal pattern to form a plurality of lower sleeve portions, each of which is attached to a shoulder portion. Gowns made in accordance with the present invention exhibit the flow and shoulder lines of a raglan sleeve construction while making efficient use of the fabric from which the gown is constructed. Methods of making garments such as surgical gowns are also disclosed. <IMAGE>

Abstract: Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of     (i) zinc,   (ii) boron,   (iii) phosphorus, and (iv) an expansion gas upon thermal decomposition. The composition is capable of forming a carbonaceous char upon exposure to heat or flame, with the proviso that the cured, unburned composition has sufficient flexibility that it passes at least 10 continuous cycles of a cold cycle test without cracking. The cold cycle test involves the following steps: the composition is applied at a thickness of 0.5 inch (12.7 millimeters) to a 10 inch (0.254 meter) section of a 4W13 I-beam having two thermocouples attached to the surface, allowed to cure at ambient temperature for 16 hours, force cured for 5 days at about 60 DEG C and subjected to the cold cycle test. For one cycle, the beam is placed in a freezer operating at a temperature between about 0 DEG F (-18 DEG C) and about -10 DEG F (-23 DEG C) for sufficient time for the steel to reach a temperature between about 0 DEG F (-18 DEG C) and about (-10 DEG F) -23 DEG C as determined by the two thermocouples attached to the surface of the beam beneath the coating, removed from the freezer and a 50 square inch area (0.0323 square meter) of the surface warmed as shown in FIGS 1 and 2 by passing a heat gun (Model No. HG 50146, Alpha Division of Loral Corp, 14 amp: minimum temperature at tip 500 DEG F (260 DEG C)) a distance of 0.5 inch (12.7 millimeter) from the surface, uniformly over the surface until the surface temperature reaches 110 DEG F (43 DEG C) within a 3 minute period, as determined by a thermocouple moved about the surface and allowed to stand for at least 2 hours at ambient temperature.   <IMAGE>
