Abstract: METHOD OF AND APPARATUS FOR AUTOMATICALLY    COMPENSATING FOR VARIATIONS IN OUTPUT RESPONSE CHARACTERISTICS OF SENSORS AND THE LIKE     Abstract This disclosure is concerned with a novel techni-que for automatically fitting the output response charac-teristic curve of a measurement sensor to that of an ideal or reference sensor through determination of output varia-tions in response to the same input stimulus near one end or point of the curve, storing the differences for automatic correction of the measurement sensor output by effec-tively superimposing the curves at such end, determina-tion of output variations at another end or point of the curve, and effectively relatively pivoting the measure-ment sensor output curve about the said one end to cause substantial superposition of the other end or point of the curve and the span therebetween, thereby to provide stored signals for automatically correcting the output response of the measurement sensor, when in subsequent measurement use, over the complete characteristic response curve between its ends or selected points.

Abstract: ABSTRACT      The invention is for an improved humane animal trap which reduces suffering to the trapped animal and reduces damage to the pelt.  The trap includes a pair of circular jaws pivotally joined by strong helical springs.  The trigger mechanism utilizes a lower lever member which extends into the stationary jaw and is biased against a bait holder/latch member by a flat spring.  An upper lever member is engageable with the lower lever member at one end and at the other end supports the movable jaw when the trap is set.  When an animal takes the bait the lever members are released from their constraints and the movable jaw moves rapidly under the bias of the main helical spring to trap the animal, just behind its head, between the trap jaws.

Abstract: Abstract:    The invention relates to a gas sensor which is con-structed of an electrically insulating base, electrodes formed on the base, and a gas sensitive film formed on the surface of the base at a portion where it detects a gas to be sensed, e.g. oxygen.  The gas sensor of the present in-vention is characterized in that the gas sensitive film is a thermally-sprayed film which is made of an oxide having a perovskite structure.  The thermally-sprayed film has a surface formed with fine cracks so that its effect-ive surface area is increased and its response time is accordingly increased.  Moreover, the thermal spraying process is carried out in such a manner that impurities that adversely affect the reliability of the sensor are avoided.  The gas sensor may have its gas sensitive film coated with a ceramic material so that its performance may be further improved while the gas sensitive film is protected.  Furthermore, it is also effective to use the electrically insulating base to support another sensors so that both sensors share a common support.

Abstract: ABSTRACT OF THE DISCLOSURE         A mould part and/or protective element of the type made of a material subject to deformation is disclosed.  A method and a device for manufacturing such a mould part and/or protecting element are also disclosed.  The mould part and/or protective element is particularly intended to be used as a mould portion in moulding an article and/or as a protective element to prevent access of soil and water to a surface portion of the article dur-ing transportation and storage thereof.  Such materials subjected to dimensional changes as can be used as mould parts and/or pro-tective elements present the advantages of being inexpensive and permitting removal of the article without difficulty.  One such material is for example cellular plaslics.  The dimensional changes, however, have entailed so great difficulties in using mould parts and/or protective elements of such materials that they have made the use of the material impossible.  To eliminate the above-mentioned disadvantage the mould part and/or  protective element of a material subjected to dimensional changes is manu-factured with the desired dimensions, starting from a least one profile strip, immediately before the mould part and/or  protec-tive element is used to mould the article or join the mould part and/or protective element to the article to protect the surface portion thereof.  Alternatively, the mould part and/or protective element of a material subjected to dimensional changes is manu-factured with the desired dimensions, starting from at least one profile strip after the strip has reached dimensional sta-bility.

Abstract: 16 DISPOSITIF DE FILTRAGE ADAPTATIF DE SIGNAUX RECUS PAR UN SONAR ACTIF POUR LA REJECTION DE LA REVERBERATION L'invention concerne les dispositifs de filtrage adaptatifs qui permettent la réjection des signaux de réverbération reçus par un sonar actif. Les signaux de voie Bi fournis par un tel sonar sont filtrés (421, 422, 441, 442) en éliminant autour de la fréquence centrale du signal reçu sur la voie une bande dont la largeur est déterminée dans un circuit de calcul (45) qui tient compte de la vitesse, de l'assiette, de l'immersion, et de la distance au fond du véhicule porteur du sonar ainsi que des directivités en site et en azimut de chacune des voies et de la durée de l'impulsion. On peut ainsi réjecter les fréquences Doppler dues à la réverbération, notamment sur la surface et le fond, tout en conservant les fréquences Doppler dues à un but éventuel. L'invention s'applique plus particulièrement aux torpilles autodirectrices et aux sonars remorqués. Figure 3

Abstract: ABSTRACT OF DISCLOSURE    Scrambled communications signalling uses signals as transmitted and received that are coded by reorganisation of binary words representing original information signals.   That reorganisation not only produces different sequences of blocks of binary words but also provides for variation of the lengths and numbers of such blocks (via memori    M100-M115) within each reorganisation.   In addition the blocks are read out in reverse order to their storage, and the preferred organisation is via a logic type pseudo random generator that must be synchronised and "seeded" at both transmitter and receiver prior to any transmission.
