Abstract: A heat shield arrangement for strip material employs insulating panels (20, 22, 24) that include an upper series (20) displaceable upwardly by power actuation means (48) to avoid damage by buckled or lifting material. Protective elements (40) projecting below the upper panels (20) are associated with sensing means (51, 51a) to actuate the raising of the upper panels (20) and are on mountings (42) able to have a limited displacement before the raising of the upper panels (20) is actuated. The power actuation means (48) act on said mountings (42) to determine the minimum force from the material that causes raising of said panels (20). To lead in deformed stock there is an increased height entry region comprising a reinforced upper structure, possibly followed by upper and lower insulating panels at decreasing heights from each other to merge into a main region of limited height. The panels may have heating means to give the strip a more uniform transverse temperature profile.

Abstract: In order to provide the possibility of interchange of roles of leading and led exchange pulse train generators, an exchange pulse train (T'') of the led generator is synchronized in phase with that (T') of a leading generator. Each generator derives its exchange pulse train (T', T'') from a respective intermediate pulse train (H', H'') by means of a frequency reduction arrangement (BKP, U). Comparison in the led generator (UGN, BKN, UGV, BKV, BKVv) of the exchange pulse trains detects a relative phase lead or lag greater than a given threshold value of the same order as the intermediate pulse train period and, in order to maintain in-phase synchronism, shortens or lengthens (BKR), as appropriate, a half period signal portion of the exchange pulse train by an intermediate pulse train period. The intermediate pulse generator is servo-synchronized by means of a master pulse train derived in a frequency adjuster from a received standard pulse train.

Zur Herstellung dieser Produkte werden die fasrigen Materialien zu einem wässrigen Brei aufbereitet, werden diesem Brei Bormineralien und Mineralsäure innig zugemischt und wird schließlich das so gebildete Gemenge nach einer gewissen Reifezeit Vliesbildungsund Faserentwässerungsmaschinen zugeleitet, entwässert und anschließend getrocknet. Es ergeben sich hiermit Produkte, die nicht nur schwer entflammbar beziehungsweise nicht mehr brennbar sind, sonder die auch ihre Festigkeit bei längerer hoher Temperatureinwirkung kaum verlieren. Hervorzuheben ist, daß diese Produkte im gängigen Naßverfahren, insbesondere auf Papier- und Kartonmaschinen, herzustellen sind.

Abstract: A graphic output system generates circular arcs of lengths up to and including a full circle of 360 degrees. Nonsymmetrical closest points are located for noninteger radius and arc center values. Incremental move commands are generated for drawing an arc either in the clockwise or counter clockwise direction which is a distinct advantage when used to drive a pen type electromechanical plotter. By dividing the generation of a 360 degree arc into eight octants, only two of the original eight directions need to be considered as candidate directions toward the next integer display matrix value to be displayed. Initialization provides a simple stopping test for any circular arc of arbitrary length and direction. Only simple addition and sign testing is used to display the circular arc.

In one embodiment the sheaves (11) are drafted through rollers (12, 13, 14) to a false twisting device (15), whereafter they are doubled in a guide (17) and taken up through rollers (18) on a cheese (19). At some stage the doubled sheaves are given a finishing twist: this may be done immediately after doubling, or the doubled sheaves on the cheese (19) may be given the finishing twist subsequently.
