Abstract: In Zeitmultiplex-Übertragungssystemen wird zur Verarbeitung der zu übertragenden Nachrichten häufig eine zentrale Steuerung (erste Einrichtung) eingesetzt. Die für die verschiedenen Funktionen vorgesehenen zweiten Einrichtungen benötigen zur ordnungsgemäßen Betriebsweise eine Vielzahl von zu den Takten der ersten Einrichtung phasensynchronen Takten. Hierfür sind entweder eine Vielzahl von Taktleitungen zwischen erster Einrichtung und peripheren (zweiten) Einrichtungen vorgesehen oder es werden über zwei Taktleitungen Takte mit der höchsten und niedrigsten Taktfrequenz übertragen und der in den peripheren (zweiten) Einrichtungen angeordnete Frequenzteiler zwangssynchronisiert. Zur Sicherstellung der Phasengleichheit bei der Frequenzteilung und zur Erfassung auch kurzzeitiger, nicht synchroner Zustände, werden in einer Verknüpfungsschaltung die, von den in beiden Einrichtungen angeordneten Frequenzteilern, erzeugten Takte mit niedrigster Taktfrequenz und der Takt mit der höchsten Taktfrequenz miteinander verknüpft. Der Schaltungsaufwand für die Verknüpfungsschaltung ist gering und erfordert lediglich jeweils ein Antivalenz-Glied und ein ODER-Glied. Die erfindungsgemäße Schaltungsanordnung wird bevorzugt im Kennzeichenumsetzergerät des Zeitmultiplex-Übertragungssystems PCM 30 F eingesetzt.

Abstract: The present invention provides a method of manufacturing coagulated grains from polymer latex and apparatus for exercising this method, said method being characterized in that a swirl of polymer latex is produced in tank, while holding it at a temperature lower than the softehing temperature of the polymer latex particles and while letting the same polymer latex as said polymer latex fall down into the aforementioned swirl liquid surface, a coagulant is added into said latex flowing-down liquid, thereby letting the coagulant disperse and scatter into the latex in the tank; thereafter, with said coagulant thus scattered as the seeds, coagulated layers are grown on their outer surfaces. According to this invention, nearly spherical coagulated grains with a uniform grain size may be obtained, while suppressing possible formation of massive coagulated matters.

Abstract: A low noise, high speed current transimpedance amplifier system (20) includes AC bootstrapping for the photodiode D1 by capacitor C2 connected between the source of the JFET Q1 and the cathode of the photodiode D1 by line (56). Line (58) also provides AC bootstrapping to the case of module (40) through capacitor C2. Simi­larly, the source resistor R3 and drain of JFET Q1 are AC bootstrapped through capacitors C1 and C4 to the emitters of the transistors Q2 and Q4 by lines (60) and (62). The collectors of the second stage transistors Q2 and Q4 are bootstrapped to the third stage transistor Q3 emitter through capacitor C8 by line (64). This bootstrapping reduces the effective input capacitance at the front end of the amplifier system (20) by a factor of up to about 100, thus reducing signal noise component in the subse­quent stage or stages to negligible compared to front end noise.

Abstract: An aqueous, radiation curable, coating composition is disclosed which comprises (A) from 50 to 85 percent, based on the total weight of the dispersion, of a vinyl functional silane, (B) from 15 to 50 percent, based on the total weight of the dispersion of a multifunctional acrylate, and (C) optionally, from 1 to 3 weight percent of a photoinitiator. The vinyl-­functional silane is the partial condensate of silica and a silane, such that at least sixty percent of the silane is a vinyl-functional silane conforming to the formula 
(R) a  Si(R′) b (R˝) c   
wherein 
R is allyl or vinyl functional alkyl 
R′ is hydrolyzable alkoxy or methoxy 
R˝ is non-hydrolyzable, saturated alkyl, phenyl, or siloxy, 
such that a + b + c = 4; and 
a ≧ 1; 
b ≧ 1; 
c ≧ 0. 
     The above-described coating composition may be applied to plastic materials and cured by exposure to ultraviolet or electron beam irradiation to form a substantially clear, abrasion resistant layer. The radiation curable composition has particular utility as an abrasion resistant coating for synthetic films, preferably polyester films. Such coated films may then be employed in automotive glazing and touch panel control applications.

Abstract: A black, infrared pass filter is disposed in front of the strobe element of an automatic rangefinding camera to provide an infrared ranging wink for ranging during the pre-exposure steps of a camera cycle. As the cycle continues, the filter is temporarily displaced from in front of the strobe element to allow a visible light, flash firing for scene illumination. Once the exposure firing is complete, the filter resumes its original posi­tion in front of the strobe element such that the filter allows only infrared light to be transmitted from the strobe element except during exposure strobe firing.

Abstract: To centre optical lenses for mechanical clamping, especially during bevelling and facetting, the invention proposes a device with a housing (10) in which a motor drive (M, R) acts via a torque divider (50), drive shafts (14, 14') and transmission elements (16, 16') on centring spindles (18, 18') in alignment with one another. The latter are arranged in guide bearings (22, 22') on projecting parts of the C-shaped housing (10) and are designed as an air bearing. The clamping angle ( alpha ) at the lens (L) can thereby be kept in the range below 2 x 8 DEG , preferably below 2 x 6 DEG . The lower centring spindle (18) in particular is axially adjustable in a free-running manner in the air bearing (22), for which purpose axially parallel and/or index-ring-shaped grooves (90) are provided at the ends of a thin-walled guide sleeve (76), between which peripheral air-cushion zones build up when compressed air is supplied. The axial infeed of the clamping spindle (18) is effected by a clamping device (24) with a yoke plate (26) and a diaphragm piston (32).

Abstract: A security document has security printing formed as a moire pattern of two superimposed sets of generally parallel lines. In each line set the line spacing varies progressively along the length of the lines so that each line set has one or more areas in which the line frequency is low and individual lines can be seen with the naked eye, and one or more further areas of high line frequency in which individual lines can only be readily distinguished by using magnification. Furthermore, the thickness of each line varies progressively between relatively large and relatively small values corresponding respectively to the areas of low and high line frequency, the ratio of line spacing to line thickness being approximately constant so that the colour or tonal density of the security printing is approximately uniform. 
     For additional security the individual line sets are printed in inks of which the colours can be differentiated by the naked eye but not by a reproducing machine used for counterfeiting. One or both of the line sets may additionally or alternatively be printed in an ink having an anti-fraud characterstic such, for example, as water-fugitivity, solvent-sensitivity or UV fluorescence.
