Abstract: ABSTRACT OF THE DISCLOSURE :     The invention concerns a brancher-mixer for optical fibres bundles intended for optical transmissions of "busbar" type. This brancher-mixer enables the luminous energy emanating from the individual fibres of a trans-mitting bundle to be first mixed and then divided between two receiving bundles. It essentially comprises two branching monofibres, each consisting of a core and a surrounding cladding and laterally arranged at one of their ends to divide into two equal or inequal parts the luminous flux emanating from the transmitting bundle. According to a first specific embodiment, the two branching monofibres remain equipped with their cladding on both sides of the common joining surface and an additional mixing monofibre is inserted between the transmitting bundle and the joined ends of the branching monofibres. According a second specific embodiment, the two branching monofibres ends are stripped from their cladding on both sides of the common joining surface and coupled by sealing or welding to form a single mixing optical channel. In both embodiments the two branching monofibres are arranged in a common casing provided with mechanical connections to establish the optical connections to the emitting and receiving bundles. There is thus provided a small low cost monolithic component for optical links with minimal inser-tion losses.

Abstract: ARCING ROD CATCHER FOR HIGH VOLTAGE FUSE     ABSTRACT:  Disclosed is an arcing rod catcher for a high voltage fuse which engages the arcing rod when the arcing rod moves during fuse operation so that the arcing rod will not bounce back or reverse directions during and after fuse operation.  Since the arcing rod movement is utilized to actuate a fuse latch assembly to release the fuse from an upper mounting when it operates, it is necessary for the arcing rod to move to the operating position and remain in that position to permanently indicate that the fuse has operated and to prevent the possibility that a blown fuse will be re-latched into a closed position.  The disclosed invention utilizes engaging fingers which allow the arcing rod to pass in one direction but prevent the arcing rod from returning in the opposite direction when the fuse operates.

Abstract: Abstract of the Disclosure Improved apparatus and process for applying locking patches of resilient resin to internally threaded articles such as nuts having openings at both ends of the threaded portions in which apparatus and process, a support and treating member, preferably a rotatable, circular table with edge notches complementary to a portion of the exterior of a threaded article to be treated, receives a succession of threaded articles heated to a temperature above the melting point of the resin to be applied and moves the articles along a path for treatment with the axes of the threaded articles in an up and down position and with the openings at the upper and lower ends of the threaded portions substantially uncovered. conduits on the support and treating member are associated with each threaded article to direct particles of heat fusible resin upwardly through the opening at the lower end of the article against a portion of the threaded surface of the article to form a first deposit of resin on an area of the threaded surface during movement along a first portion of the treatment path and a turning device at an intermediate location on the treatment path turns each threaded article, as it reaches that location, a predetermined angle so that the conduit associated with the article directs resin against a further area of the threaded surface to form a second deposit of resin during movement along a further portion of the treatment path. The temperature of the article, the rate of movement along the treatment path, the supply of the resin particles, the location of the turning device, and the turning angle may be correlated so that thin edge portions of the first resin deposit may be spaced from or may be overlapped by thin edge portions of the second resin deposit up to an extent that the total thickness of resin in the overlapped portions may approximate the thickness of the central portions of the first and second deposits of resin.

Abstract: Abstract of Disclosure Photoelectronic light barrier apparatus, used to detect interruption of a beam of light passing from a light trans-mitter to a light receiver incorporating an operational photoelectric converter, is protected against the effects of unwanted light by providing an auxiliary photoelectric converter in the vicinity of the operational converter.  The auxiliary converter detects the presence of unwanted light and its output is subtracted with appropriate weighting from that of the operational converter to produce a weighted difference signal. In this way obstruction or interruption of the light barrier is reliably detected up to a specific intensity of the unwanted light. Should the intensity of the unwanted light be even higher the apparatus is biased to the side of safety because the weighted difference signal results in an indication that the light barrier is obstructed.

Abstract: ABSTRACT OF THE DISCLOSURE One type of smoke detector has a housing forming a dark chamber into which light is directed on a path viewed by a smoke sensing photo-cell.  Smoke in the viewed light path scatters light to the cell exciting the cell to alarm state if the smoke is of density predetermined to be dangerous.  The detector is tested for its ability to respond to the predetermined smoke density by means of an external owner-operated button. Depressing the button turns a lever or bell crank which intercepts the light path in the chamber and scatters light to one or more large areas within the dark chamber.  These secondary areas in turn rescatter the scattered light to the photocell simulating smoke and exciting the cell to alarm state. The primary light scattering surface of the bell crank and the areas of secondary  light scatter are large enough that the light ultimately scattered to the photocell is equivalent to that scattered by smoke of the predetermined density.

Abstract: ABSTRACT OF THE DISCLOSURE:         This invention relates to a method for sensing and to a sensor for detecting the activity of gaseous anhydrides in an oxygen-bearing gas.  There is provided a solid state electrolyte element having oxy-anions of the element forming the anhydride to be detected, this electrolyte element being constituted of two parts, one part being an alkali metal salt or an alkali-earth metal salt containing the oxy-anions and the other part being an oxygen ion-bearing electrolyte.  A reference electrode is set in contact with the other part of the electrolyte element whereas a detection electrode, remote from the reference electrode, is in contact with the one part of the electrolyte element.  The elec-trolyte element and detection electrode are arranged such that they are free to come into contact with the gaseous anhydride to be detected.  The reference and detection electrodes are arranged such that a difference of potential occurs therebetween when a sample of the anhydride to be detected is contacted with the de-tection electrode and with the electrolyte element.  Moreover, the electrolyte element is heated to a temperature such that a loga-rithmic variation in the concentration of the anhydride to be detected causes a proportional and substantially linear variation in the difference of potential, the temperature being below the fusion temperature of the electrolyte element.  A potentiometric measurement device is connected to the electrodes for measuring the activity of the anhydride to be detected by measuring that difference of potential.
