Abstract: ABSTRACT          A system for monitoring the performance of an internal combustion engine includes a pressure sensor that has a mounting configuration external to cylinders such that it is capable of monitoring the pressures within two adjacent cylinders. The signal output of the sensor is filtered to remove undesired engine noise and blank out those signals which are unrelated to compression and firing, thereby reducing errors in the signal output. After filtering the signals to reduce noise,a successive number of samples related to compression and firing are obtained to provide an adequate number of signals which will average out mechnical and electrical noise. From the successive samples, a straight line approximation of the slope of the cylinder pressure curve, relative to crank angle, is obtained. The derived slope values are compared with upper and lower limits to determine whether or not the pressure within the engine cylinder of interest is acceptable. If the upper limit is exceeded or if the value obtained is less than the lower limit a fault in the cylinder operation is assumed to have occurred. This fault measurement and analysis procedure is repeated a prescribed number of times and if the problem continues to occur over a predetermined consecutive number of measurements, then a fault indication is generated.

Abstract: DL23,411 BROADBAND SEIZURE FOR CATV TRUNK CABLES by GOPALLKRISHNA GANPATRAO NADKARNI        Abstract of Disclosure A tubular extension on a trunk station terminal housing has a cylindrical opening therein that is closed by a coaxial connector plug, the opening receiving one end of a tubular sleeve section on a seizure member whose position is fixed in the housing with the ID and   of the sleeve being coaxial with the cylindrical opening.  And a ooaxial cable transmission line that is connected to the plug has its inner conductor passed through openings in the plug, extension and sleeve and seized by a clamping screw in the other end of the member, the ID of the sleeve being selected for receiving the inner conductor of the largest coaxial cable with which the trunk station is to operate.  The position, OD and length of the sleeve; the ID of the cylindrical opening; and the length that the sleeve extends into the cylindrical opening are selected for making the characteristic impedance of the sleeve portion of the transmission line section approximately equal to that of the coaxial transmission line for causing the return loss looking into the plug to be generally constant over a broad band of frequencies for coaxial cable center conductors of different diameters.

Abstract: ABSTRACT     A method and apparatus for connecting a static inverter to a rotating motor, such as a three phase induction motor, is disclosed.  A high frequency, low voltage signal is provided to the rotating motor through a suitable rectifier and inverter, which are in turn controlled by a suitable regulator and oscillator.  The current is maintained at full load value, and the fre-quency is lowered in a controlled manner while the impedance of the motor is monitored.  When the frequency of the inverter equals the rotational speed of the motor, the impedance of the motor increases dramatically.          The supply voltage is then permitted to control the motor, and is allowed to rise to the rated value, causing the motor to be fully fluxed.  Apparatus for implementing the method are disclosed.

Abstract: ABSTRACT   A probe for measuring temperatures in a hot gaseous medium such as the gases inside the shaft of a blast furnace.  A first tubular member extends from a base structure such as a blast furnace wall into the gaseous medium.  Successively smaller, second and third tubular members are concentrically positioned inside this exterior tubular member.  Preferably, an exterior protective member also surrounds the first tubular member.  A refractory material is interposed between the exterior protective member and the first tubular member to minimize temperature fluctuations in the body of the probe itself.  Thermocouple leads extend longitudinally in an air space between the second and third tubular members and then protrude to the exterior of the probe.  A forward fluid coolant passageway is formed inside the third tubular member.  This forward passageway connects at its terminal end with a radial fluid passageway which is formed between a radial flange on the fourth tubular member and a closure plate on the first tubular member. A rearward fluid coolant passageway is also formed between the first and second tubular members.  Cooling efficiency is enhanced because the fluid coolant is maintained in the cooler center of the probe until it reaches the terminal end of the probe which is typically its hottest section.

Abstract: The disclosure describes a method for the preparation of metallic alloys containing an alkali or alkali-earth metal, such as lithium, and a host metal, such as aluminum. Initially, an active organic solution of the alkali or the alkali-earth metal is prepared, and a source of the alkali or alkali-earth metal which are both brought together with one another. On the other hand, a metallic structure containing the host metal is prepared, the metallic structure is brought together with the organic solution which is kept in touch with the source of metal until there is formed an alloy of the host metal and of the alkali or alkali-earth metal with the metallic structure, and the alloy possesses an activity which is determined by that of the organic solution. The organic solution then acts as transfer agent of the alkali or alkali-earth metal towards the host metallic structure. To prepare a negative electrode, the alloy is brought together with an electrolyte, such as a thin polymeric film. The disclosure also describes the electrodes as well as the electrochemical generators produced by using these electrodes. Considerably improved properties of cycling are obtained.
