Patent SE-8500818-L (SE)
Inventor: FAGERLUND G
IPC: C04B41/65
Filed: 1985-02-20
Abstract: Salt damage to concrete structures as a result of contact with dry salt, sea water or like salt environments can be avoided in the case of new structures and repaired in the case of damaged structures by applying a layer of slag cement concrete to the structures. The ability of slag cement to absorb chlorides and to delay chloride penetration greatly lengthens the time required to initiate corrosion of the reinforcing irons by the chlorides present and to reduce the effect of chlorides in conjunction with frost. The slag cement-concrete also has a leaching effect on chloride-infected structures and in the case, for example, of an old bridge pier having applied thereto a layer of slag cement-concrete the carbonation front is halted and a new front is formed in the protective layer. The chloride profile extending through the pier is also changed as a result of chloride irons diffusing out from the infected concrete and being neutralized in the protective layer. The slag cement can also be applied to form a salt-frost resistant layer by spray casting techniques, this being difficult to achieve with conventional shotcrete base on other types of cements.

Abstract: The bottom surface of a cooking vessel (1) is provided with a plurality of concentric grooves (3) by form rolling. The grooves are then provided with a coating (5) to absorb radiation heat from a hotplate. Thus in use the grooves absorb radiation heat while the annular surfaces (4), between the grooves which are in contact with the hot plate absorb contact heat. The resulting vessel also has a very strong construction since the annular surfaces between the grooves act as reinforcing ribs.

Abstract: The invention relates to a supporting cupola (11) for the propellant (6) of a base-bleed gas generator for a projectile, shell or the like. The supporting cupola (11) is arranged in the discharge aperture (7) of the gas generator and provides a reduced gas outlet area from the base-bleed combustion chamber (4) during launch of the projectile. The supporting cupola (11) is made of a material which is easily eroded by the hot combustion gases, such as magnesium. The reduced outlet area increases the pressure in the combustion chamber during the acceleration stage of the projectile so that an improved ignition of the propellant (6) and reduced risk of extinguishment is obtained. Due to erosion of the cupola material the outlet opening area increases with time providing a regressive burning rate of the propellant which means an increased base-bleed effect with respect to the firing range of the projectiles.

Abstract: The number of zero-crossings in each band of a dual-tone multifrequency (DTMF) signal is counted and compared with that in immediately preceding measurement periods. The magnitude of any difference is established and when it is at least equal to a threshold value, pref. one, the input signal is considered to be a DTMF signal. The energy parameter, representative of the tone energy in a signal, is measured in real time in each band, and three threshold values for the difference from average values determined. The measured difference values are compared with the thresholds to determine if a DTMF signal exists. An interference frequency is accepted when occurring in successive measuring periods.
