Abstract: 27554 ACTIVE TERMINATION FOR A TRANSMISSION LINE Abstract of the Disclosure A tri-state buffer having the output thereof electrically connected to the input thereof is utilized to provide an active termination for a transmission line carrying data, addresses, commands or other information. The tri-state buffer is enabled by a strobe signal so as to insure that the transmission line will be stable through the time period of the strobe signal when data, commands, addresses or other information is being transferred. A tri-state buffer having the output thereof electrically tied through a resistive element to the input thereof is utilized to provide an active termination for a transmission line carrying strobe-type signals. The tri-state buffer is always in an enabled state. The resistance element is used to help match the line impedance of the transmission line. This reduces the load on the strobe signal source and also reduces transmission line rinsing due to impedance mismatches.

Abstract: ABSTRACT OF THE DISCLOSURE A phase servo loop for the head drum of a video tape recorder employs a reference signal to initiate the production of a trapezoidal or ramp signal and a head position signal to sample and hold the values of the trapezoidal signal.  The sampled and held value is employed to phase lock the head drum to the reference signal.  A variable delay counter applies a variable delay to the head position signal.  A flip-flop is used to detect a predetermined phase relationship between the reference signal and the head position signal.  The out-put  of the flip-flop controls an up-down counter to selectively increase or decrease a number stored therein according to whether or not the above predetermined phase relationship exists.  The content or number in the up-down counter is preset into the variable delay counter by the head position signal which is thereafter clocked to its capacity at a high clock rate. The time for the variable delay counter to reach its capacity is thus variable in dependence on the number preset into it. A start-up circuit provides a high clock rate into the up-down counter when the equipment is first turned on to provide rapid phase lock and later reduces the clock rate to minimize jitter.  When editing is being performed the number stored in the up-down counter can be held when switching from playback to recording so that no disturbance will occur in the head drum phase control. When playback is resumed, updating of the up-down counter is restarted.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a novel process for the pre-paration of an improved rabies vaccine and the vaccine obtained by this process, which vaccine, compared with customary vaccines, is distinguished by a considerably increased activity in relation to contaminating proteins and thus produces reliable protection against rabies infections without triggering off side-effects.          The preparation process is characterised in that when rabies viruses which have been multiplied in poultry embryos by known methods are harvested, only the heads of the embryos are used and from the cell extract obtained therefrom, by far the greater proportion of the substances contained therein which have a lower or greater density than that of the rabies antigen are separated off by differential centrifugation and density grad-ient centrifugation, whilst at the same time, the rabies antigen is selectively concentrated, and the resulting purified antigen concentrate is further processed to give the ready-to-use vaccine by known methods.  Multiplication of the viruses can be carried out in duck embryos, chicken embryos and quail embryos.

The lens holding ap-paratus is universally mounted to the frame of the reader to enable the lens holding apparatus to move freely in response to changes in the angular disposition of the glass plate with respect to the horizontal plane.  The lens adjusting assembly has an eccentric finger which translates the rotating motion of the knob and shaft into a vertical force, which moves the lens.  The lens adjusting assembly has a barrel, socket in the barrel and key slots along the socket.  The shaft has a par-tially-spherical end and keys which slidably and pivotally fit into the socket and key slots.  The simultaneous slidable and pivotal operative connection of the shaft to the lens adjust-ing assembly enables the operator to adjust the lens regardless of the angular disposition of the lens adjusting assembly with respect to the shaft.  The connection also enables the lens holding apparatus to move freely in response to changes in the attitude of the glass plate with respect to the lens.

Abstract: ABSTRACT OF THE DISCLOSURE:          A method of manufacturing superficially hydrophilized filling bodies for interphase mass and/or heat exchange units.          In accordance with the invention, polypropylene filling bodies in a vessel are brought into contact with a gas containing 0.5 to 10 vol. % of sulphur trioxide and less than 5 vol. % of free oxygen, at a filling body temperature ranging between 10 and 50 °C.  The gas temperature is at most 10 °C higher or at most 35 °C lower than the filling body temperature.  After interruption of the contact between the filling bodies and the gas which can be constituted by a contact gas present in the sulphuric acid production, the filling bodies are brought into contact with a gaseous or liquid medium which is apt to react with sulphur trioxide and which can be selected from the group comprising water, ammonia, alkali carbonate or hydrogen car-bonate, and alkali or alkali earth the metal hydroxide.  During the reaction which can be carried out in a rotatable vessel, the position of individual filling bodies is intensively varied.          This method permits to advantageously solve the problem of homogeneity of the hydrophilizing reaction.

Abstract: ABSTRACT OF THE DISCLOSURE A novel rotary prime mover or engine is provided herein including a flywheel block having at least one pair of opposed jet reaction engines therein which, when operative, cause rotation of the flywheel.  The novel engine includes a generally cylindrical casing, the casing including an axial air intake, an axial exhaust outlet and bearing means at each circu-lar end thereof to support a longitudinally arranged shaft.  A flywheel block having a main cylindrical section of slightly less diameter than the diameter of the casing is mounted on the longitudinally arranged shaft and is arranged intermediate the air inlet and the exhaust outlet, the longi-tudinal shaft having a fuel  inlet passage therein, preferably being a fuel passage concentrically bored in a solid shaft.  The flywheel block includes at least two balanced, diametrically opposed, jet reaction engines re-cessed within and secured within the cylindrical section of the flywheel block, each being disposed along a chord of the main cylindrical section, each jet reaction engine having its exhaust flowing along an imaginary ex-tension of the chord of the cylindrical section of the flywheel block. Each jet reaction engine comprises (i) a hollow cylindrical housing, (ii) a cylindrical ignition head threadedly longitudinally adjustably secured at one end of the housing, the ignition head having an air inlet throat leading to a plurality of circumferentially disposed, longitudinally ex-tending air inlet passages, and a central bore accommodating an ignition device, (iii) an exhaust liner threadedly longitudinally adjustably secured at the other end of the housing, the liner having a central longitudinally extending exhaust passage having an exhaust gas inlet throat,  (iv) a fuel infeed zone,  (v) a radial fuel inlet for admitting fuel to the fuel infeed zone, and (vi) a combustion zone within the housing disposed between the Abstract - 2 ignition head and the exhaust liner; a fuel infeed line within the fly-wheel block connected between the radial fuel inlet to the fuel infeed zone and the fuel passage through the longitudinal shaft, the fuel infeed line including automatically actuated valve means therein; and a source of ignition power connected to the ignition device through the casing.  In this way, operation of the jet reaction engines causes powered rotation of the flywheel block, so that power may be taken off the longitudinal shaft.          Thus there is now provided a simple engine,  having a minimum of moving parts, in which the rotary member, the jet reaction member and the stationary casing are so interrelated as to provide an ultimate efficient engine.
