Abstract: In this process, using preheated hydrogen-containing hydrogenation gas under elevated pressure and elevated temperature, if appropriate with addition of an additive, in a liquid-phase system, the heavy oil is fed to a preheater and then subjected to a hydrogenation reaction in a reactor cascade. The reaction products are passed to a hot separator. Only a part of the total quantity of hydrogenation gas required in the liquid phase is admixed with the mixture of heavy oil and additives, which has been raised to the process pressure but not yet preheated. To simplify the process and to save energy, the other part of the quantity of hydrogenation gas is heated up by heat exchange with the gaseous top product from the hot separator in a first heat exchanger designed as a gas heat exchanger and added to the preheated mixture of heavy oil and additives and hydrogenation gas. <IMAGE>

Abstract: @ A device for burglary alarm protected doors intended to prevent unintentional unlocking of the lock mechanism of a door when the alarm circuit is operative, including aslide (3), displacably arranged at the outside door plane, arranged to be locked by means of an electromagnet (7) in a position extending across the key hole of the lock mechanism when the alarm circuit is operative. According to the invention, the slide (3) is arranged to influence an electrical swith means (8) when in a position extending across the key hole, thereby interrupting a voltage feed from the alarm circuit to the electromagnet (7). An initial displacement movement of the slide (3) in direction away from the key hole results in that the switch means (8) closes the voltage feed circuit to the electromagnet (7) from the alarm circuit, whereby the electromagnet (7) locks the slide (3) after an initial displacement movement against further movement away from the key hole. As soon as the slide (3) is no longer manually influenced, the slide (3) after an initial displacement movement against further movement away from the key hole. As soon as the slide (3) is no longer manually influenced, the slide (3) returns to the position influencing the switch means (8), and the voltage supply to the electromagnet (7) is interrupted.

Abstract: The invention discloses means to reduce the noise and vibration of gear sets (12, 14) by (a) minimizing the transmission error resulting from variations in the mesh stiffness at different phases of tooth engagement and (b) reducing the maximum rate at which load is transferred to the driven gear. A substantially constant mesh stiffness is achieved by shaping the teeth (11,13) and the field of contact (20) so the product of incremental tooth contact line length and tooth pair stiffness per unit length of tooth contact line integrated over the field of contact (20) does not vary significantly as the tooth contact lines (21) move across the field of contact (20). In addition, the maximum rate at which load is transferred to the driven gear is substantially reduced by shaping the teeth (11,13) so the tooth contact lines (21) intersect the entry and exit boundaries (23, 24) of the field of contact (20) at an angle.

Abstract: In a video recorder, in which the available frequency range has been extended to about 7.5 MHz by means of circuit means, a frequency- modulated sound carrier (T1u, T2u) is recorded in the upper frequency band (B). During the reproduction, the frequency is converted back to the original frequency (5.5 or 5.74 MHz) by means of a mixed carrier (M) obtained from the line. This frees the frequency-modulated sound carrier of timing errors and additional interfering modulation. Figure 1. <IMAGE>

Abstract: Fuel cell stack (58) incorporating an internal elec­trolyte supply system employing a variety of arrangements of grooves (78) and passages (80)(82) in bipolar plates (62) of the multi­plicity of repeating fuel cells (60) to route gravity-assisted flowing electrolyte throughout the stack. The grooves (78) route electrolyte flow along series of first paths which extend horizontally through the cells between the plates thereof. The passages route electrolyte flow along series of second paths (82) which extend vertically through the stack so as to supply electrolyte to the first paths (78, 80) in order to expose the electrolyte to the matrices (66) of the cells. Wicks may be employed in the grooves for facilitating transfer of the electrolyte to the matrices as well as providing support for the matrices. Additionally, the passages (82) may by-pass certain of the grooves and supply electrolyte directly to other of the grooves. Dual grooves can be utilized as an alternative to single grooves. Finally, the passages may be connected to the grooves by a step which produces a cascading electrolyte flow.

Abstract: In a packet-switched communications network wherein multiple node stations are interconnected by a transmission medium and each service user terminals, each station is responsive to a request for a circuit-switched call from a source user terminal of the own station to transmit to the transmission medium a control packet containing a source address, a destination address, a unique address and a time slot number identifying the position of a time slot in which a circuit-switched signal from the source user terminal is to be contained. The control packet is followed by a message packet which contains the same unique address as that sent with the control packet and a plurality of time slots which are identified by the time slot numbers of a plurality of such control packets. The destination station receives the control packet and a message packet having the same unique address as that contained in the control packet and extracts the circuit-switched signal from the received message packet in accordance with the time slot number contained in the received control packet and applying the extracted signal to the user terminal identified by the destination address.

Abstract: An apparatus for applying convergence corrections to correct positional and misconvergence errors in a CRT employing a self-converging deflection yoke for magnetic deflection of an in-line colour gun assembly. Convergence correction coil windings are coupled to the deflection windings with the inductances and resistances of the convergence windings selected to match the time constants of the associated deflection windings. The applied deflection current signals are thereby apportioned between the deflection and convergence coils to modify the beam deflection and provide a beam deflecting flux proportional to the commanded deflection signals and a beam deflection centre that is independent of the pattern written on the screen. The resulting currents in the deflection coils and convergence coils are a substantial replica of the commanded deflection current signal waveforms.
