Abstract: The present invention relates to a method to determine the temperature of one or both surfaces of the two surfaces of a Peltier element. One then calculates the temperature difference (dT) between the surfaces from a known relation for the Seebeck voltage (U.sub.p) as a function of the temperature difference and the mean temperature (T.sub.i) of the element from a known relation for the temperature dependence of the internal resistance (R.sub.i) of the element. Finally, to the mean temperature (T.sub.i) one adds and from it subtracts respectively half the temperature difference (dT) between the surfaces.

Abstract: An enclosed active armor arrangement wherein the panels that form the enclosure have a product of the density and the thickness of the side panels that is greater than the product of the density and the thickness of the armor panels to provide for a reflective action on the detonation waves of the explosive. This reflective action accentuates the destructive effect on the incoming explosive charge jet.

Abstract: A reactive armor arrangement consisting of two mutually parallel metal sheets with an interior sheet of incompressible formaldehyde compound. Upon impact with a hollow jet explosive charge, the incompressible layer causes the outer metal sheets to push outwardly into the path of the hollow jet explosive charge.

The holder is dimensioned to fit into a mine-fuze location provided in the antitank mine, where the booster charge is in fuzed relationship with the explosive charge contained by the mine. The holder is also provided with connectors for initiators for initiating one or more explosive charges located in the ground, the booster charge being in fuzed relationship with the initiators when the holder and mine fuze are attached.

Abstract: A method for the manufacture for the tubes or shafts of a composite material and having a low weight, whereby a blank of a material that can be pressformed and which has a substantially even thickness of material is subjected to isostatic pressing on or in a formation tool thereby providing a shell or a liner (15) of an intended shape and profile and having a mainly by substantially thickness of material, and on or in said shell or liner (15) another material is applied and is bound, for instance a highstrength material like glassfiber, carbon fiber or aramide fiber, so that the liner (15) and said other material (17) provide a solid integral composite tube or composite shaft.

Abstract: A safety means for an ordnance fuze. The arrangement includes an arming rotor (1) which is held in a safe position (A) by means of a half-shaft (6) which in the safe position of the rotor engages a first recess (7) located in the rotor. A clock mechanism (9) is provided so as to rotate the half-shaft (6) about its axis to a rotational position in which it no longer engages the rotor (1), thereby enabling the rotor to be rotated to its armed position. The rotor has provided therein a second recess (11) into which the half-shaft (6) is able to rotate should it be rotated at an excessively high speed, thereby returning the rotor to its safe position.

Abstract: An arrangement in a mine which is capable of being neutralized, comprising detecting means (33) operative to detect a neutralization of the mine, and initiator means (3) adapted to initiate detonation of a spotter charge (5) incorporated in the mine in response to the detection of a neutralization, and a spotter (1) which is arranged to be propelled from the mine by said detonator charge to the surface of the ground, in order to disclose the location of the mine. A penetrator (4), which is intended to drive a pathway through the ground to facilitate passage of the spotter (1), is arranged forwardly of the spotter in the mine, as seen in its direction of travel. The spotter (1) is capable of forwardly driving the penetrator (4) during a first phase of the spotter firing sequence; and the arrangement further includes a separating device (9) which is intended to separate the spotter from the penetrator during a second phase of the firing sequence.

Abstract: A telescoping torque transmitting shaft comprising a shaft having at least three longitudinally extending circumferentially spaced guide grooves and a sleeve axially slidably surrounding the shaft and having an inner counter groove opposite each guide groove. Torque is transmitted between the shaft and the sleeve by a row of balls for each guide groove, each ball being partially received in its guide groove and partially received in the counter groove opposite its guide groove. At least certain of the balls in one row are of resilient elastic material; all others are substantially harder. Bias imposed upon the shaft by the resilient balls, urging the shaft in one lateral direction relative to the sleeve, maintains every ball in torque transmitting contact with both the shaft and the sleeve, while the harder balls in the other rows, by such contact, maintain the elastic balls compressed for exerting such bias.

Abstract: A guide mechanism for a projectile (2) which is intended to be fired from a barrel (3) with the aid of propellant gases. The projectile comprises a plurality of elongated fins (5) which are journalled at one end thereof and which are arranged to occupy a folded position during passage of the projectile through the barrel. The fins are subjected to a fin-extending force with the aid of a piston (7) which is arranged for movement in a housing (6) in the guide mechanism. The guide mechanism also incorporates a channel means (10) through which during a pressure increase phase of the propellant gases in the barrel the gases are passed to a chamber (9) located on one side of the piston and build-up a piston working pressure (p) in said chamber. The channel means (10) has arranged therein a valve (11) which is operative in throttling the channel means during a pressure reduction phase of the propellant gases.

Abstract: Arrangement for interconnecting a projectile and a projectile extension component. The projectile and the extension component each incorporates its own connecting element which are capable of being introduced into each other by causing one of the connecting elements to be so deformed as to be retained in its deformed state in the second connecting element. The connecting elements are capable of being introduced into each other with the help of the firing forces whose effect is immediate when the projectile and the extension component are fired from the barrel of a weapon.

Abstract: Arrangement for a thermal, steam-powered engine in a submarine vehicle, for example a torpedo. A condenser is so arranged as to separate the exhaust from the engine into a condensable exhaust fraction and into a non-condensable exhaust fraction. A compressor, which is connected to the engine for the purpose of silencing, is so arranged as to compress only the non-condensable exhaust fraction which, after compression, is discharged through an exhaust outlet into the surrounding sea water. The condenser is in the form of a sleeve which for silencing purposes encloses both the engine and the compressor. A sound-deadening gap is arranged between the condenser and the hull of the vehicle.

Abstract: Mortar ammunition with a projectile body and a tail tube containing the necessary propellant charge. The tail tube and the projectile body constitute two separate components which, for the purpose of being loaded into the mortar, are capable of being lowered in turn into the mortar via its barrel until they come into contact with each other inside the barrel. When the mortar is fired the projectile body will leave the mortar without taking with it the tail tube. The projectile body and the tail tube make contact with each other via a girdle fixed to the tail tube, said girdle being caused by the gases from the propellant charge to become detached from the tail tube and to become securely attached to the projectile body, so that the girdle is carried out of the barrel by the projectile body.
