Abstract: Shaping glass sheets into complicated shapes having convex and concave curvature portions requires a continuous shaping surface onto which a supported glass sheet is heated and conformed. Glass shaping molds are usually made of materials that can be harmful to the glass or the shaping face of the molds can be harmed when there is direct contact between the hot glass and the mold. The present application discloses a composite fabric liner comprised of high temperature resistant ceramic fibers and glass fibers useful as a shaping liner between the glass sheet and the mold surface.

Abstract: In a lock detection circuit, an input pulse signal at frequency f₀ is compared with an output pulse signal from a frequency divider (5) to produce a control signal representative of a difference in frequency or phase between the input and output pulse signals. A voltage-controlled oscillator (4) generates pulses at a frequency f₀ × N (where N ≧ 2) when the control signal indicates that the frequency or phase difference is zero or pulses at a variable frequency when the control signal indicates that the frequency or phase difference is non-zero. The frequency divider (5) divides the frequency of the pulses from the oscillator (4) by a factor N to generate the output pulse signal. A decision circuit (6-11) is provided for detecting when the pulses generated by the oscillator (4) during an interval between pulses of the input pulse signal are equal to at least N to give an indication that a phase alignment is established between the input and output pulse signals. If N is equal to or greater than 4, the decision circuit (6-11) may comprise a frequency divider (12) for dividing the frequency of the input pulse signal by a factor M (where M ≧ 2) to define the count interval between successive pulses from the second frequency divider (12), so that phase alignment occurs when MN pulses of the input pulse signal exist between the count interval.

Abstract: This system is applicable to channels that use packet, frame or message protocols, for which a half-duplex communications controller (1) is connected to a multiplexer (2) which, in turn, is connected to two different clock circuits (3, 4), to provide the controller with a working frequency in the reception mode and another working frequency in the transmission mode. 
     The system includes a buffer memory (11) in which the data to be transmitted are stored at a rate much higher than that at which they are transmitted to the line, these data being transferred to a serializer (15) which delivers the data to the line (8) through a transmission interface (16) at the line transmission rate. 
     The system is normally in the reception mode and changes from this state when the transmission operation is desired, after having verified that no reception is taking place.

Abstract: What is described is a safety bolt for the wings of windows, doors or the like, especially a rotary locking device for the wings of turn- and-tilt windows and doors, which consists of a spring catch with a relatively small bolt engagement depth predetermined by the spring excursion and of a bolt movable by means of a handle and having an engagement depth exceeding the bolt engagement depth of the spring catch. An essential feature is that only the push bolt 7 manually displaceable, by means of attached operating handle, between its release position and its bolt engagement position can be blocked in its bolt engagement position against disengagement, whereas the spring catch, although it can be brought into its release position counter to the return force of the spring by means of an operating handle 10, nevertheless subsequently returns  resiliently again into its initial position, in which it can interact automatically with the bolt loop assigned to it. The handle 10 of the push bolt 7 carries a rotary knob 21 projecting into a slot-shaped or groove-shaped recess 23 of the fixed push-bolt guide 6, 11, whilst the slot-shaped or groove-shaped recess 23 of the fixed push-bolt guide 6, 11 has a widening 24 at least at its end assigned to the maximum bolt engagement depth of the push bolt 7. Only within this widening 24 can the rotary knob 21 be adjusted transversely into a blocking position. <IMAGE>

They can also be used for improving the keeping quality and recording and reproduction characeristics of optical recording media that use organic dyes in the form of thin films. Representa­tive examples include N, N-lower alkyl substituted nitroso­anilines, phenol or naphthol derivatives having at least one nitroso group, nitrosodiphenylamine and its derivatives and 1-picryl-2, 2-diarylhydrazyl free radicals.
