Abstract: A ramming unit comprises a tooth (5) which is placed at the front parts of the unit. The tooth is arranged so that it can be raised and lowered, and in its raised position the rear side (5a) of the tooth coacts with a shell (2) or the like when this is rammed in a firearm by means of the ramming unit. In its lowered position the tooth permits the passage of a bag charge (4) or the like which is to be placed behind the shell in the bore of the barrel. The tooth and the other parts are made with force relieving means which transfer substantial parts of the forces arising on the tooth in connection with the ramming direct to said other parts of the ramming unit, and not via the supporting means of the tooth.

Abstract: In order to facilitate the handling or manipulation of products, especially printed products, typically newspapers and magazines or the like, the same are grouped together into a band worm-like, foldable composite formation. As a result, the printed products have imparted thereto, also in their dimensions, a defined identity which can be gainfully employed after a possible intermediate storage during each further processing thereof. At the same time there is facilitated the storage (stacking, palletizing and so forth) and the removal from a storage area as well as the transport thereof, especially since the access to the composite formation renders seizable, in a defined manner, each product which is engaged therefrom.

Abstract: PCT No. PCT/SE81/00215 Sec. 371 Date Feb. 25, 1982 Sec. 102(e) Date Feb. 25, 1982 PCT Filed Jul. 10, 1981 PCT Pub. No. WO82/00317 PCT Pub. Date Feb. 4, 1982.This invention relates to a method and a device for controlling the cooling of internal combustion engines in order to reduce the corrosive wear of cylinder barrels and piston rings. The corrosion substantially is caused by the sulphur content of the fuel. In a Diesel engine the combustion of the fuel always takes place at a relatively great air excess, which implies that the formation of sulphur trioxide exceeds the formation of sulphur dioxide. Together with the water vapor in the flue gases, in addition to sulphurous acid the stronger sulphuric acid is formed. The corrosion in combination with the wear result in a much too short life of the cylinder liners and piston rings and constitute a significant economic problem. Known tests show for the corrosion of steel in flue gas with 0,01 and 0,02% SO3-content a very distinctive maximum at about 150 DEG  C., but corrosion minima on both sides of said maximum. The corrosion can be reduced by maintaining the surface temperature for cylinder barrels and piston rings below the lower temperature limit for maximum corrosion due to SO3-content in the flue gas by tempering the coolant while the engine is subjected to a load up to a certain partial load, and at increasing output and upon arrival at said partial load causing an abrupt increase in the surface temperature to a value above the upper temperature limit for said maximum corrosion, and maintaining the surface temperature thereafter above this value by tempering of the coolant.

Abstract: The firing grate of a waste combustion installation consists of grate bars (5a, 5b) with a grate support (8) for the material to be burned. On the underside of these grate bars are flow ducts for cooling air. The end side of the grate bars is provided with an outlet (16) into the combustion chamber. The outlets serve for the lateral supply of cooling air as combustion air. By expedient design of the geometry of the grate bar, an optimum cooling effect and uniform distribution of the secondary combustion air on the grate support can be achieved. As a result, there is uniform combustion, extensively independently of the waste bed. The uniform design of the grate bars makes maintenance and stocking replacement parts easier. <IMAGE>

Abstract: An automatic gain control arrangement is provided for an analog to digital (A/D) converter in a television signal processing system. A gain-controlled source of analog signals applies a video information signal to the input of an A/D converter. The A/D converter produces digitized video signal samples at an output which is coupled to a digital peak detector. The digital peak detector detects the level of the digital samples of the synchronizing signal components. The detected sync signal level is compared with a desired value or range of values. If the detected sync signal level is not at the desired level or is outside the desired range, the count of a counter is incremented or decremented accordingly. The count of the counter is converted to an analog voltage which is applied to the gain-controlled signal source to control the level of the analog signal applied to the A/D converter. The analog voltage may also be combined with a control voltage produced by an analog peak detector, which detects the level of the input signal to the A/D converter, to produce a composite gain control signal.

Abstract: In a highway train, a wheeled and steerable, motor-driven vehicle is combined with at least a first load carrier having its forward end portion rested on a first "fifth wheel" supported by the rear portion of the tractive vehicle. An auxiliary wheeled vehicle has a front portion with a second "fifth wheel" supporting the rearward end portion of the first load carrier. A second load carrier has its forward end portion rested on a third "fifth wheel" supported by a rear portion of the auxiliary vehicle. An additional wheeled vehicle supports the rear end portion of the second load carrier. While en route, the first load carrier is supported solely by the first and second "fifth wheels" in such a manner that it is free to occupy a limited angular position in a generally horizontal plane, relative to both the tractive vehicle and the auxiliary vehicle. The auxiliary vehicle has fixed front wheels and rear wheels which are turned through a steering mechanism, in response to any horizontal angular displacement occurring between the first load carrier and the auxiliary vehicle, as when the train passes through a curve. In this manner, the auxiliary vehicle always returns itself into a straight line position with respect to the first load carrier.
