IPC: G02B6/00

Abstract: A penetration assembly for an optical fiber cable comprises a pair of axially-aligned cylindrical sleeves 13 surrounding an optical fiber cable 6. An air-tight seal is formed between the optical fiber cable and the sleeves by means of glass connectors 16 connected to the optical fiber cable and flexible metal connectors 15 connected between the glass connectors and the inside of the sleeves. Each glass connector 16 comprises a plurality of cylindrical sections each having a different coefficient of thermal expansion having a value between that of the optical fiber cable 6 and that of the flexible metal connector 15. The coefficient of thermal expansion of the glass connector 16 changes in a stepwise manner from the section connected to the optical fiber cable 6 to the section connected to the flexible metal connector 15. This step-wise change in coefficient of thermal expansion reduces the thermal stresses exerted on each section and prevents cracks due to thermal stress, a common problem with the resinous materials presently used to form air-tight seals in penetration assemblies. Since the air-tight seal between the optical fiber cable and the sleeves is formed from glass and metal, it is more resistant to radiation than presently used seals formed from resinous materials.

Abstract: An airlfuel ratio monitoring system (40) in an IC engine, using an oxygen sensor (10) of the concentration cell type which has an inner electrode layer (14), a microscopically porous layer (16) of oxygen ion conductive solid electrolyte and an outer electrode layer (18) to be exposed to the exhaust gas and exhibits a sharp change in the level of output voltage (V s ) in response to a change in the air/fuel ratio in the engine across the stoichiometric ratio. To ensure accurate monitoring of the air/fuel ratio even though an average level of the sensor output (V s ) changes for some reasons such as aging of the sensor (10), the monitoring system (40) produces a variable reference voltage (V A ), with which the output (V s ) of the oxygen sensor (10) is compared, by first adding a definite voltage to or substracting a definite voltage from the output voltage (V s ) of the sensor (10) depending on the result of comparison between the sensor output (V s ) and the reference voltage (V A ) and then smoothing the voltage (V T ) resulting from the addition or subtraction treatment. To prevent misjudgement of the air/fuel ratio by unintentional intersection of the sensor output voltage (V s ) attenuating after responding to a change in the air/fuel ratio across the stoichiometric ratio and the reference voltage (V A ), the system (40) includes control means (86,88,90) for varying the time constant at the voltage- smoothing operation according to the manner of a change in the sensor output voltage (V s ).

Filed: 1984-05-25
Abstract: A method for applying a skid-resistant surface layer to roads involves the application of a layer of chippings which is then covered by a layer of bituminised sand. This sand fills the voids between the chippings such that, during subsequent compression with a roller, the chippings cannot rotate and remain in a random orientation. The resulting surface layer contains a relatively large proportion of chippings having a sharp or pointed edge uppermost and thus possesses good skid-resistance properties. 
     The method may be adapted either for use in the re-surfacing of an existing road or for applying a skid-resistant surface during the construction of a new road.

Abstract: The invention relates to looms and more specifically to a device for cutting the weft thread (3) outside one or both edges of a weave (10). A pointed edge (13) on a stop (12) faces the front part of the loom and is fixed relative to the reed (2) of the loom and accompanies it in its beating-in motion. A counterhold (11) occupies a primarily fixed position relative to the frame of the loom and is disposed with a region (17) with a softer material than in the edge (13). The stop and the counterhold are movable relative to one another and assume in one of their end locations positions in which the edge (13) interacts with the region (17) with the softer material. The edge thus preferably abuts this softer material and thereby cuts the weft thread (3). The softer material normally comprises an elastic polymeric material e.g. rubber, plastic, etc. and thereby forms a block which is replaceably fastened in a holder (16).

Abstract: In a quarternary differential PSK demodulator, a QPSK input signal is applied to first and second synchronous detectors to which carriers with a 90-degree phase difference therebetween are respectively applied from a voltage-controlled oscillator. A first double-balanced phase detector multiplies the outputs from the synchronous detectors. A second phase detector squares the output of the second synchronous detector. A third double-balanced phase detector provides multiplication of the outputs of the first and second double-balanced phase detector to generate an output having four times the frequency of the outputs of synchronous detectors to cancel the information carried by the input PSK signal. A loop filter converts the output of the third phase detector to a DC phase control signal to be applied the voltage-controlled oscillator.
