Abstract: METHOD AND APPARATUS FOR SEGMENTING CHARACTER IMAGES                         Abstract A method and apparatus are disclosed for seg-menting character images in an optical image system where the character images have a predetermined pitch.  The optical image system generates character information in the form of a successive series of scan lines of data. Profiles of the character images being scanned are generated, and a profile segment meeting certain criteria is selected.  The center of the selected profile segment is located, and segmentation points between the character images are established as a linear function of the character image pitch and located center.  The segmen-tation points are integer multiples of the pitch.

Abstract: Silicon hydrides are produced by acid hydrolysis of ternary silicon alloys. According to the process there are made to react an industrial ternary alloy of the formula MxM2ySiz, in which M1 is a reducing metal, M2 is an alkali alkaline-earth metal, with a dilute acid selected from hydracids and orthophosphoric acid, at a concentration of 2N to 6N, by adding the ternary alloy in the form of fine powder to the acid, the reaction being preformed between ambient temperature and 90 DEG  C. The various hydrides are condensed, and separated by fractional evaporation under partial vacuum. The silicon hydrides-silane, disilane and higher polysilanes-after purification can be used as silicon vectors, depending on their chemical nature, particularly in the industries of electronic components, photovolaitic cells, photocopier drums and for frosting light bulbs by the dry method.

Abstract: ABSTRACT LOUDSPEAKING TELEPHONE INSTRUMENT. A loudspeaking telephone instrument comprises a transmit path comprising a microphone (1) and comb filter (2); a receive path comprising a comb filter (3), a frequency shifter (4) and a loudspeaker (5); and a hybrid circuit (6).  The frequency shifter (4) shifts the frequency of a signal applied to its input by a fixed amount and the comb filters (2,3) are arranged so that the frequency shifted signal falls in their stop bands.  This increases the available gain in the loudspeaking telephone instrument before instability occurs.  The spacings of the pass and stop bands of the comb filters (2,3) are at a multiple of the frequency by which the frequency shifter shifts that of its input signal.     Figure 1.

Abstract: ABSTRACT      A method of specimen treatment preparatory to conducting an immunoassay is disclosed whereby a microbial protein is solubilized by a detergent at elevated temperatures and in the presence of an alkali or alkaline earth metal ion.  At elevated temperatures, the detergent is soluble.  However, at lower tempera-tures, the presence of the metal ion renders the deter-gent insoluble so that it is prevented from interacting in the immunoassay procedure.  A specific application is in the solubilization of the principal outer membrane protein of Chlamydia trachomatis.

Abstract: ABSTRACT           A circuit for use in conjunction with a microprocessor for refreshing, checking and correcting data signals stored in a dynamic memory.  The circuit utilizes a direct memory access controller for transferring data signals stored in successive locations of the dynamic memory to a non-existent peripheral.  Data signals appearing on a data bus as a result of the data transfer, are applied to a parity checking circuit for generating an interrupt signal to the microprocessor in response to detection of parity errors in the data signal.  The microprocessor then performs a data recovery routine in which correct versions of the data signal stored in a non-volatile memory, are transferred for storage in the dynamic memory under control of a microprocessor.  Parity errors in data signals stored in the dynamic memory are thus corrected prior to being accessed by the microprocessor.

Abstract: ABSTRACT OF THE INVENTION A reinforced composite structure is provided comprising a heat resistant chemically bonded layer of a ceramic composition mechanically attached to a metallic substrate.  The structure includes a metallic anchoring matrix characterized by a plurality of spatially and cooperably arranged reinforcing elements, the matrix being attached to the substrate and projecting from the surface thereof with the spatially arranged reinforcing elements of the matrix collectively defining a ceramic-occupiable zone of finite thickness adjacent to and following the surface configuration of said substrate, the zone having at least confined therein the heat resistant chemically-bonded ceramic in intimate contact with the reinforcing elements.   The chemically-bonded ceramic layer is produced by mixing a low-temperature chemical bonding agent with the ceramic composition which is then heated to a low temperature below the normal sintering temperature of the ceramic composition generally employed when the chemical bonding agent is not present, whereby the layer of reinforced heat resistant ceramic is strongly mechanically bonded to the substrate by virtue of matrix attached to the substrate.  The invention is particularly applicable to the production of heat resistant abradable seals for use in aircraft turbine engines.

Abstract: APPARATUS FOR DETECTING WATER IN FUEL     Abstract of the Disclosure Diesel fuel tends to deposit an insulating coating on surfaces it contacts.  A probe, preferably in the form of a siphon tube, is coupled to a detection circuit which is responsive to either low resistance or high capacitance between the probe and ground.  The probe is initially uncoated to make a resistive coupling to the fuel container when accumulated water touches the probe.  When insulating deposits from the diesel fuel or other fuel oil coat the probe, capacitive coupling will occur between the probe and the accumulated water.  In either case the presence of water triggers an output signal by the detection circuit.

Abstract: ABSTRACT OF THE DISCLOSURE    In a cooling zone of a continuous annealing line engineered to continuously process lognitudinally travelling steel strip, the strip is first slowly cooled to a desired temperature at a rate of not higher than 20°C/sec by means of a jet stream of cooling gas ejected against the surface of the strip and subsequently quenched to a desired temperature at a rate of not lower than 70°C/sec.  Thinner strip is quenched by high-speed gas-jet cooling that is effected by ejecting a jet stream of cooling gas against its surface, while heavier strip is quenched by bringing it into contact with the perimeter of cooling rolls cooled by a coolant.          Namely, quenching is achieved either by high-speed gas-jet cooling or roll cooling depending on the thickness of the strip being processed.  A cooling apparatus for implementing the cooling method described above comprises a high-speed gas-jet cooling zone where the strip is cooled by means of a jet stream of cooling gas ejected against its surface and a roll cooling zone following the high-speed gas-jet cooling zone where the strip is brought into direct contact with a plurality of cooling rolls.  Means to exert longitudinal tension on the strip travelling through the roll cooling zone are provided at the entry and exit ends thereof.
