Title: Detection of overheated axle boxes
IPC: B61K9/06
Filed: 1968-06-07
Abstract: A hot axle box detector comprises means for measuring the temperature of two axle boxes on the same vehicle and means for giving an alarm if either temperature exceeds a threshold value dependent upon the sum of the temperature signals and a constant preset value. The temperature signals x 1 , x 2 , Fig. 2, are applied to threshold circuits 15, 16 and give alarms if they exceed the threshold level applied at 17, 18. The level is determined by subtracting a fixed level h 3 from the x 1 and x 2 signals and summing the results at 22. A fraction of the summed signal is added to a fixed level h 1 at 24 to provide the threshold level. A limiter 26 may be provided to prevent the threshold exceeding a preset maximum. The subtractors 19, 20 may be omitted.

Title: Method of treating semiconductor devices
IPC: H01L21/3105
Filed: 1969-03-18
Abstract: While a surface region of a semi-conductor body is being converted into an insulating layer, the body is heated in an atmosphere containing a hydrogen halide to getter detrimental metal impurities in the coating and body. In a typical example silicon wafers are first heated in a flow of oxygen or steam to form a thin genetic oxide layer, and then in nitrogen which has been bubbled through an azeotropic solution of hydrogen chloride maintained at 110 C. During gettering the oxide layer thickens and if desired the entire layer may be formed during heating in the gettering atmosphere. Finally the body is annealed by heating in hydrogen. Hydrogen bromide or iodide may be used instead of the chloride as may hydrogen fluoride if this does not attack the insulation used. Layers of silicon monoxide and/or nitride may be likewise treated during formation.

Patent ES-385760-A1 (ES)
Title: System of time-division multiplex transmission via communications satellites
IPC: H04B7/155
Filed: 1970-11-21
Abstract: A system at each station is described to detect the beginning of a message first containing a start signal and to detect the station address in a TDMA system. The system stores detected suspected signals for a number of preceding frames that occur in an expected time slot. A first majority decision is made with respect to the stored start signal and if a positive decision is made the next detected start signal is accepted for processing. A positive decision for the start signal majority decision enables the station addresses to be evaluated by a second majority decision. This arrangement eliminates the need of redundancy codes for the start signal and the station address, said redundancy codes occupying too much space in the available time slot.

Patent ES-430001-A1 (ES)
Title: Start-up control circuit for SCR deflection
IPC: H04N3/16
Filed: 1974-09-12
Abstract: A boost voltage delay circuit for deflection circuit utilizing trace and commutating switches to generate deflection current in a deflection winding. A supply voltage boost circuit derives voltage from an inductor coupled between the direct current voltage supply and the commutating switch, boosts and regulates it, and supplies this regulated boost voltage to the commutating switch. The boost voltage delay circuit monitors the commutation switching action by rectifying voltage variations appearing across the inductor to charge an R-C circuit for several cycles of commutation switching action before the voltage across the R-C circuit rises sufficiently to turn on a transistor which enables the boost voltage circuit to supply boost voltage to the commutating switch. Commutation loss due to failure of the commutating switch to become reverse biased under applied boost voltage is thereby prevented.

Title: Method and apparatus using proportional residual gas storage to reduce NO{HD x {b emissions from internal combustion engines
IPC: F02M25/07
Filed: 1974-10-10
Abstract: Reduction of NOx emissions from a four-cycle stratified charge internal combustion piston engine is accomplished by (a) spark ignition of a rich mixture in a first chamber containing residual exhaust gas, followed by (b) torch ignition of rich mixture in a second chamber under turbulent conditions, causing (c) torch ignition of a stratified charge in a lean mixture in the main combustion chamber. The result is a reduction in peak temperature in the combustion process, with consequent reduction in NOx emissions in the engine exhaust gases. Exhaust gas is not recirculated. Said first chamber, which contains residual gas from the previous combustion cycle, contains the spark gap between spark plug electrodes and the spark gap is located near a restricted connection between the first and second chambers and remote from a closed end of the first chamber. Means are provided for changing the volume of said first chamber while the engine is operating, in accordance with variations in load on the engine.

Title: Fractionation of air by adsorption
IPC: B01D53/04
Filed: 1976-03-25
Abstract: Ambient air, during an on-stream period, is passed serially through a pretreatment adsorbent bed removing moisture and carbon dioxide therefrom and the thus dried and purified air then passed through a main adsorbent bed selective for retention of nitrogen, the oxygen-rich effluent being collected in an expandable receiving vessel. Nitrogen of high purity, is desorbed by suction from the main bed in a direction chamber to that of the initial air charge and passes from the main bed into and through the pretreatment bed to a collection vessel. Preceding the vacuum desorption step both the pretreatment bed and the main bed are rinsed with the high purity nitrogen product gas from a previous stage in the operation. Following evacuation the beds are repressured with a portion of the oxygen-rich gas drawn from the expandable receiving vessel. At least two parallel trains of adsorbent beds are employed in alternating timed sequence for continuity of operation. By operation in the described manner there are recovered for any desired use, nitrogen of high purity and an oxygen-enriched gas product.
