Abstract: In a semi-active system of missile guidance, simple illuminating devices, designated as transmitters only, are used for illuminating the target, instead of expensive target tracking devices. The illuminating devices are directed at the targets by the target locating equipment, within the periods of target information renewal. As compared to the target tracking systems, the half width of the directive diagrams of the illuminating device is definitely enlarged and so dimensioned that the illuminated solid angle encompasses the maneuvering space of the target within the period of information renewal.

The articulation devices of the core and rotary element are rectilinear and are preferably orthogonal and corresponding.

Abstract: A method of dry cooling coke using a coke transporting bucket which has a removable cover with an exhaust pipe extending from the interior of the bucket to an exterior exhaust connection and a cooling shaft for the coke comprises directing red hot coke into the bucket, covering the bucket with the cover and transporting the coke to the cooling shaft and connecting the exhaust pipe to the exhaust system while the bucket is in the shaft and emptying the bucket into the cooling shaft. The coke transporting bucket comprises a container having a bottom discharge which is closable by a flap and a removable cover which seats around the rim of the container to seal it. An exhaust pipe is carried by the cover and it extends into the interior thereof for removing gases from within the bucket and delivering them to an exterior connection which is connectable to an exhaust line.

Abstract: A take-up mechanism for safety belts in vehicles comprises an automatic belt winding assembly which is connected to a windup assembly which includes a motor having a piston which rotates relative to an associated cylinder to drive the belt winding assembly in a direction to tighten the belt, for example when an emergency arises such as a potential accident. The drive motor includes a piston having a vane portion rotatably mounted in a cylinder so that either the piston or the cylinder is rotatable for a short rotation period upon the ignition of a pyrotechnical drive charge which when ignited provides a propellent for driving the motor. The construction of the mechanism is such that kinetic energy stored in the rotating masses of a clutch are used to effect a positive coupling of the take-up mechanism with the shaft carrying the wound up seat belt. The drive motor thus has a limited rotational path which is shorter than the length of the belt portion to be retracted.

Abstract: A device for stopping the machine drive of a needle movable in cooperation with a rotary hook of a sewing, embroidering or tufting machine upon a thread breakage comprises a thread cutting mechanism which includes a thread catcher movable through the needle path and a switching mechanism which is connected to the drive for disconnecting it and which becomes effective upon a thread breakage. The device includes a movably mounted thread feeler carrier having a thread feeler which is adapted to be located between the needle and the rotary hook. The drive mechanism for actuating the thread catcher includes control cams which are engageable with lifting cams so as to project the feeler out of the path of motion of the thread between the needle and the rotary hook. The thread feeler is associated with a piezoelectric element and the deflection of the feeler by the thread produces a pulse which regulates the drive mechanism for the sewing machine and effects the stopping thereof when the threads are cut.

Abstract: A method for the dry cooling of coke comprises transferring the coke from the coke oven to a special bucket which is moved over a charging hole of a cooling pit. The space between the bucket and the charging hole is closed off and sealed against the atmosphere and a shutter which closes the top of the charging hole is moved upwardly and then transversely off the charging hole to open it as an intermediate charging guide piece is moved in position between the hole and the bucket for the transfer of the coke therebetween.

The device advantageously runs on wheels which are located outside the frame which seals the sapce between the charging bucket and the charging pit. The frame of the sluicing device advantageously includes a sealing element which engage into a recess seal combined around the charging hole.

Abstract: A method of operating a cyclic synthesis gas-ore reduction process comprising supplying a carbonaceous material and preheated oxygen to a synthesis gas reactor to produce a hot synthesis gas, partially cooling said hot synthesis gas by directly passing the same through a regenerator and thereby storing the sensible heat of the hot synthesis gas in said generator. Further cooling said synthesis gas by reheating liquid for a vapor generator, and then reheating said further cooled synthesis gas and supplying it to an ore reduction reactor and generating a reduced product and an off gas. Directing the generated off gas to the synthesis gas reactor via said regenerator to heat the off gas to around 100.degree. C. by transferring said stored heat.

Abstract: To ensure functioning and permanent readiness for operation of a sand-dispensing device for motor vehicles, which comprises a sand container and at least one sand channel with a sand outlet facing the wheel, two closing means are provided. The first one closes the outlet of the sand container, i.e. the passage into the sand channel, and the second one closes the sand outlet. The two closing means open simultaneously, so that the sand is discharged from the sand container directly onto the roadway. To stop dispersion, the outlet of the sand container is closed earlier, so that the sand channel can get discharged. Only then the second closing means closes the sand outlet of the channel and protects the discharged sand channel and the first closing means against humidity and mud.

Abstract: In addition to protective helmets, a breathing protection is required time and again. This purpose is served by a protective breathing mask. It must be made possible to put the mask on in a simple way with one hand, but reliably and in combination with the protective helmet. To this end, the mask is provided with locking means comprising coupling hooks to be moved by means of spreading dogs. While pushing the dogs together, the coupling hooks are displaced outwardly, to spread apart at the end of this motion. Upon putting on the protective mask and releasing the hold of the spreading dogs, the hooks get clamped to the protective helmet where they engage catch seats to lock the mask to the helmet. The breathing mask is thus firmly held toward the face to be protected. The mask is removed in an equally simple way, by pushing the spreading dogs together.

Abstract: A sewing assembly equipped with a feed mechanism comprises a work holder which is supported by two swing arms hinged to each other, and moved by two stationary positioning motors. Each of the positioning motors is in positive drive connection with a slide carrying one of the swing arms. The swing arm directly carrying the work holder comprises a non-buckling center bar, a cross bar, and two prestressed spring steel strips by which the ends of the cross bar are connected to the end close to the swing axis of the center bar. The two member linkage with the stationary motors and the light-weight and yet non-bending swing arm result in a very low inertia of the feed mechanism.

Abstract: Modern fiber material filters for floating particles remove floating substances from the air or gas flow conducted through them. In addition to the pure screening properties it is electrostatic forces, generated either by the flowing action or by accessory equipment, which make it possible to obtain the high degrees of separation, such as at least 99.97%, for example. An electrostatic filter for floating particles contains an electrode on each of the inlet and discharge sides. The electrostatic field through which the retaining ability is increased is generated by an oppositely polarized voltage. The floating particles filter according to the invention contains an electrode on the discharge side in the form of a metallic vapor deposit on the dielectric, folded filter material. This electrode retains every last floating particle which, above all, are then still located within the filter material itself, so that in case of a power failure, they cannot blow away.
