Abstract: 1. A circuit arrangement for monitoring the presence of rail vehicles within certain track sections by means of two induction loops (2a, 2b), the changes in the inductivity of which are detected in each case by an oscillator (1a, 1b), the oscillations of which are converted to square pulses and are divided in each case in a frequency divider (3a, 3b) and are fed to an evaluation circuit (6a, 6b) following the frequency dividers (3a, 3b), said evaluation circuit delivering an occupied or free signal depending upon the inductivity change at any time, the circuit arrangement also comprising means which allow the direction of travel to be determined by comparing the times of the two signals originating from the evaluation circuit (6a, 6b), characterised in that two d.c. separated clocks (11a, 11b) alternately switch the oscillators (1a, 1b) to the inoperative state, in that the oscillators (1a, 1b) are d.c. separated from one another, in that the clocks (11a, 11b) are interconnected via d.c. -separated coupling networks (13a, 13b), are quartz-stabilized and mutually synchronize one another, in that each oscillator (1a, 1b) is followed by a frequency divider (3a, 3b) which is dynamically set to a defined position, and in that a separate evaluation circuit (6a, 6b) is associated with each of the two frequency dividers (3a, 3b) following the oscillators (1a, 1b).

Abstract: An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42-42) each being a composite comprising a substrate portion (50) and a layer (52) of a coating material which has a relatively high hardness disposed on an outer surface of the substrate portion. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with at least portions of longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength as well as suitable flexibility and cable bending performance. Further, because the cable in a preferred embodiment has an all-dielectric sheath system, it is inherently lightning, corrosion and EMP resistant.

Title: Process for producing electrolytic lead and elemental sulfur from galena
Inventor: FRACCHIA PIERLUIGI
IPC: C01B17/06
Filed: 1990-07-30
Granted: 1998-06-02
Abstract: A process for producing electrolytic lead and elemental sulfur from galena comprises the steps of leaching galena with an acidic aqueous solution of ferric fluoborate, with ferrous fluoborate, lead fluoborate, and elemental sulfur being formed according to the reaction: 2 Fe(BF4)3 + PbS  ~  2 Fe(BF4)2 + Pb(BF4)2 + S.          In a further step, a solid residue produced in the leaching step is filtered off, the solid residue comprising elemental sulfur and galena gangue.  The solution of ferrous fluoborate and lead fluoborate formed in the leaching step is subjected to electrolysis in a diaphragm electrolytic cell in which pure lead is deposited at a cathode of the cell and ferrous ions are oxidated to ferric ions at an anode of the cell.  A solution of ferric fluoborate regenerated at the anode n the electrolysis step is recycled to the leaching step so that the solution is subjected to the galena leaching step.

Abstract: INSULATED GLASS/FLUSH OUTER SURFACE ARRANGEMENT                 Abstract of the Disclosure A  pre-fabricated  window  assembly  for  flush-appearance glazing comprises a conventional single-pane or dual-pane assembly. In the latter case, the spacer el-ements are inset from the peripheral edges of the window assembly.  One of two types of extrusion is provided along each peripheral edge of the window assembly which provides a bonding surface to which the flush mounted lite  is adhered by means of a bonding cement plug.  The extrusion on one side of each pair of opposed sides of the window assembly is provided with a quick push-on  or hook-on connector which mates with a complementary connector on the mullion or grid frame.  The other extrusion on the opposite side of the window unit, for each pair of opposed sides, is similarly  configured,  except  that  the  connector  is  a permanent connector for permanent securing of the extrusion to an appropriate mating fastener on the grid frame.  Where a dual glazed window assembly is used, each of the extru-sions is provided with a channel in which the peripheral edge of the inboard lite is mechanically gripped.   The extrusions, in that event, are also provided with a rib or flange forming with the inner side of the inboard lite a recess into which a bonding agent may be placed to adhere the inner lite to the extrusion.  The extrusions and the bonding cement are all applied in the factory to make the complete pre-fabricated window assembly.

Abstract: SERVO SHIFT CONTROLLER FOR A FORWARD/REVERSE MECHANISM            Abstract of the Disclosure A mechanical clutch is provided to selectively interconnect a forward or reverse gear member to a transmission shaft.  The clutch is operated by a servo piston and fork structure.  The servo piston is slidably disposed in a housing and urged in the forward select position by a spring.  The housing and servo piston cooperate to define two fluid chambers which are maintained in a separated condition when the forward select position is established.  One chamber is in fluid communication with a fluid system that is controlled to provide fluid at two distinct pressure levels, depending upon various vehicle operating parameters.  The other chamber is connected with a selectively engageable fluid operated friction clutch which is effective to assist in establishing at least the reverse drive ratio within the transmission.  The lowest level of fluid pressure in the one chamber is not sufficient to cause the piston to overcome the spring force and thereby move the clutch to the reverse select position.  The second pressure level is, however, sufficient to cause such movement.  In the reverse select position, the chambers are fluidly interconnected and the fluid clutch can be engaged by the fluid pressure supplied through the second chamber from the first chamber.

Abstract: Un système de ligne de transmission ouverte permettant de localiser une entité (110) se déplaçant le long d'un chemin prédéterminé emploie des transmissions provenant d'un émetteur éloigné et indépendant (106), en particulier une station de radio ou de télévision payante. Le système comprend deux récepteurs, les deux étant accordés à la fréquence d'émission. L'un des récepteurs (101) reçoit des signaux en provenance directe de l'émetteur (106) par l'antenne (104). L'autre récepteur (102) reçoit le signal en provenance de l'émetteur (106) par une ligne de transmission ouverte (107). Un processeur (103) traite les signaux provenant des deux récepteurs pour détecter la présence de l'entité. Le système peut utiliser des émissions sur différentes fréquences provenant d'une pluralité d'émetteurs espacés les uns par rapport aux autres (402; 403; 404) afin d'assurer la fiabilité et pour minimiser les effets de signaux à chemins multiples. Le système peut employer une ligne de transmission ouverte à vitesse variable (507), comportant un moyen de conducteur central (1100) ayant un élément central perméable (1202) équipé d'un conducteur à enroulement hélicoïdal (1201). L'inductance du conducteur central, et par conséquent la vitesse de propagation de la ligne, est modifiée par un signal à variation périodique (Vm) appliqué au conducteur. L'entité provoque différentes variations de phase pour les vitesses de propagation différentes. Le processeur (103) compare ces variations de phase pour localiser l'entité.

Granted: 1994-01-25
Abstract: A METHOD FOR ACTIVE FEEDBACK SUPPRESSION     Abstract of the Invention A process to reduce the howl condition in a radiotelephone when the microphone picks up audio from the speaker. The condition is detected by first lowering the speaker volume (103) and measuring the michrophone volume for a corresponding decrease (104). The speaker volume is then increased (105) and the microphone volume is again measured for a corresponding increase (106). If the microphone volume follows the speaker volume, a howl condition has been detected. To eliminate the condition without the volume fluctuations being noticed by the parties conversing, the microphone and speaker volume is reduced in small increments (114) until the condition is eliminated.
