Abstract: TITLE: Gas sensor and detection system comprising such a sensor.     ABSTRACT     The invention provides a gas sensor consisting of a housing which is divided into two compartments 3 and 4 by means of a fluid filter 2, e.g. a bed of activated charcoal. Compartment 3 has an inlet channel 5 and contains a first gas-sensitive semiconductor 6, the measuring device. Compartment 4 has an outlet channel 7 and contains a second gas sensitive semiconductor 8, being used as a reference device. The value of the electric resistances of devices 6 and 8 will increase or decrease when the compartments 3 and 4 contain either an oxidising or a reducing gas. The sensor is used in a gas detection system in which an electronic circuit which follows determines the ratio between said resistances and the ratio of the reference device and a reference resistance. These ratios are subsequently compared to certain limiting values, and when these values are exceeded, a detection signal will be produced.     4 Claims, 4 Drawing Figures.

Abstract: ABSTRACT          A mullite containing cementing mix particularly suited for silicon carbide containing shapes is shown that is adapted to be initially activated when mixed with water and set by air drying so that it can subsequently permanently set by firing the mortar in situ.  The mullite component is first mixed in a raw batch with ball clay, a chemically active alumina, bentonite, sodium silicate and a borosilicate glass frit and then after this composition is mixed with water and air dried, the cement is fired in place to react certain of the constituents in the mix and sinter the mullite phase in a bonded relation with the surface of the shapes being cemented in place.  A refractory furnace liner or the like may thus be fabricated for example wherein the silicon carbide containing shapes forming the liner are held in place with an inert strongly adhering cement having substantially the same thermal expansion properties as the shapes being bonded.

Abstract: A REAL TIME USAGE INDICATOR FOR A PROCESSOR SYSTEM   ABSTRACT OF THE INVENTION     This invention is a device which permits the percentage of real time consumed by software tasks of a telecommunications switching system or other process controller to be measured and displayed on a percentage meter.  The relative percentages of different real time tasks are displayed by the relative intensities of particular lamps mounted on a control panel of a meter.  Non-standard, user defined, software tasks may be selected for display on the meter.  Software tasks which overshoot a predetermined amount of time provide an indication of this by lighting one of a number of different lamps.  Each of these lamps measures a predetermined amount of overshoot time.

Abstract: Abstract of Disclosure A carton clamp having a frame adapted to be mounted on a materials-handling machine, especially an automatically guided vehicle, includes clamp arms coupled directly together, independently of the frame, by motor-driven screw-type linear actuators which selec-tively open and close the arms.  A centering assembly coupled to each clamp arm corrects for any imbalance of clamp arm speeds relative to the frame which may occur due to the fact that the screw actuators are free to move relative to the frame.  The direct interconnection of the clamp arms by the screw actuators effectively doubles the clamping force which would otherwise be obtainable if the actuators were fixed to the frame.
