Abstract: A circuit arrangement is provided for serial data transmission between a plurality of subscriber stations via a data bus, the circuit arrangement comprising data transmitters that are in a high-impedance state in the passive condition and in a low-impedance state in the active condition. In such a circuit arrangement, a mutual control of the subscriber stations occurs by way of the data bus without the assistance of additional control lines. This is achieved with the assistance of a recognition circuit having two data receivers in fail-safe circuitry connected in an antiparallel manner at their inputs and having their outputs connected to a logic element. The control arrangement is particularly suited for utilization in remote control devices.

Abstract: 2.1 The object of the invention consists in optimising the functional reliability of the thread separator by so constructing the gripper needles that the frontmost thread of a warp thread concatenation of a fabric is reliably seized in isolation on each occasion and that any risk of piercing and gripping the successive thread is avoided. 2.2 It is proposed to design the gripper needles (4) so that they are constructed as sectioned needles which are provided with special hooks (6) (7) of which at least two are arranged to oppose each other in the same or parallel plane with respect to the upper and lower sides of the strip of fabric associated with the line of thread, the points (10) (11) of the gripper needles being directed towards the respectively opposite thread surface (12) and the concave recesses (14) (15) of the gripper needles shaped to conform to the diameter of the thread to be picked up on separation in such a way that piercing by the needle points of the thread to be separated and gripping of the successive thread are avoidable. <IMAGE>

Abstract: Low sodium sponge goods, such as soda crackers, oyster crackers, pretzels, and flavored snack crackers, having a substantially uniform texture and pH throughout, a substantially uniform surface color, a pleasant mouth feel and taste are obtained by the process of the present invention. The sodium content of the sponge goods is reduced, for example, to less than or equal to 42 mg Na⁺ per 14.2 gm serving, by replacing at least a part, preferably all, of the sodium bicarbonate with potassium carbonate for neutralization of the sponge acidity resulting from fermentation and for leavening. Hot spots resulting from localized concentrations of potassium ion are avoided by: 1) applying the potassium carbonate substantially uniformly and directly upon the surface of the sponge to hydrate and solubilize the potassium carbonate and/or 2) using potassium carbonate having a particle size distribution of about 98% by weight being finer than 100 mesh. Other baked goods, such as baked sweet goods can be made with a sodium content of less than or equal to 42 mg Na⁺ per 14.2 gm serving by replacement of sodium bicarbonate with potassium carbonate.

Abstract: A line deflection circuit in a picture display device in which a bidirectional supply switch controlled at the line frequency, as inductance and a bidirectional deflection switch likewise controlled at the line frequency are arranged in series between the terminals of a supply voltage source. A line deflection resonant network is connected to the deflection switch. By means of a forward control of the period of conductance of the supply switch the amplitude of the line deflection current is changed at the field frequency and by means of a feedback control of the said period this amplitude is maintained constant during a time interval which is short with respect to the duration of a field period. The line amplitude is substantially independent of the value of the line frequency and the trace capacitor is switchable as a function of the line frequency.

Abstract: A method of, and apparatus for, checking the loading and unloading of a tanker having at least one tank provided with a metal connecting pipe adapted to be coupled via a coupling to one end of a hose having a coupling at two ends, which hose can be coupled to a metal connecting pipe of a storage tank. The hose used is provided with an electric conductor (30) extending between the couplings for the dissipation of electrostatic charges and the chassis of the tanker is grounded. A first inductive coupling is effected between one of the connecting pipes and an interrogator (41) of an electromagnetic identification system, and a second inductive coupling is effected between the other connecting pipe and a passive responder (42) generating a coded signal in an interrogation field. Thus an interrogation field formed by the interrogator cooperates via the first inductive coupling, the one connecting pipe, the electric conductor of the hose, the other connecting piepe, and the second inducting coupling with the responder. The code of the responder is checked prior to loading or unloading.

Abstract: L'invention a principalement pour objet un dispositif de mesure de phase. L'utilisation des filtres adaptés (140) permet d'augmenter le rapport signal/bruit d'un signal reçu. Toutefois, si on envoie une pluralité d'échantillons du signal comportant chacun une phase différente, le signal présent à la sortie du filtre adapté (140) à un instant quelconque, risque d'être un mélange de phase de deux échantillons successifs. L'utilisation d'un filtre impair (141) permet de déterminer les seuls instants pendant lesquels la mesure de phase correspond à la phase d'un seul échantillon du signal. L'invention s'applique principalement à la démodulation, détection ou au décodage d'émissions de télévision de radio ou des transmissions de donnée en modulation de phase.

Abstract: Polysilicic acid having a limiting viscosity not less than twice that of monosilicic acid and a water-soluble salt of a metal capable of forming a hydroxide in water are added to the water to be treated. The polysilicic acid can be prepared by polymerizing water glass. Where the flocculant is prepared in the form aqueous solution before adding to the water to be treated, the flocculant is preferably maintained at a pH not less than 2 or not lower than 11. The gel time of the polysilicic acid may be prolonged by addition of a substance able to generate ferric ion in the solution. Thus the flocculant can maintain high aggregation ability after being stored for a long time. The silicic acid solution may be polymerized before being added with such a ferric ion generating substance.
