Abstract: A machine for receiving and compressing agricultural harvested crops, such as hay, straw or grass, to roll-shaped bales with a coiling chamber, which can be swung open and moved by means of a chassis comprises a front chamber housing and a rear chamber housing, which is coupled pivotably to the front chamber housing for forming the boundary of a front and a rear bale-forming space. A first bale conveyor is allocated to the front bale-forming space and a second bale conveyor, which can be caused to move in a direction of rotation opposite to that of the first bale conveyor, is allocated to the rear bale-forming space. The first bale conveyor and the second bale conveyor are guided over at least one upper and one lower stationary deflector rolls which are supported so that they can rotate at the housing wall parts.

Abstract: In optical demultiplex transmission equipment, light conductor fibers are used for decoupling individual diffracted light signals of different wave length from a multiplex signal. These fibers have their input end regions arranged close together side-by-side in the diffraction plane of a diffraction grating. The respective diffraction angles of the light signals impinging on the grating are adjusted, by variation of the wave length of the light signals, so that the diffracted light beams fall into the input ends of respective output light conductor fibers. However, only every nth light conductor fibre is used for decoupling the various light signals (in which respect n is a natural number greater than one) so there may be spacer fibers disposed between the light-receiving output fiber. In this way, no complex output fibre guide is required and changes in channel spacing are possible without any structural changes being required.

Abstract: The invention relates to a machine which is pulled or attached to a three-point attachment on a tractor and used for the harvesting of corn or similar stalk-like crops. The machine has a cutting device and a chopping blower arranged subsequent thereto with slide-in rollers to which the crop is supplied by a cross-conveyor running transversely to the direction of travel of the tractor. The cross-conveyor is designed as a cutting and supplying device, cutting the crop at any point in the working area, holding it above the cut area and supplying it in an approximately upright or inclined position, opposite to the conveying direction, to the slide-in rollers or a chopping machine with simultaneous release.

Abstract: A method and apparatus are described for adjusting clock pulses of time-equidistant digital line scanning values of a moving-image signal present in a composite color video signal to a clock used in a digital transmission link by means of a moving-image coder. In the transmitting part (10) of the moving-image coder, self-identifying stuffing characters are inserted into the string of image scanning values if clock deviations are found. The identification may be carried out by means of an additional bit or, alternatively, by a special code word when this is first removed from the supply of image scanning values. In the receiving part (30) of the moving-image coder, the stuffing character is recognized and removed and the original character string is restored.

Abstract: The invention relates to a method of and to an apparatus for attaching cables 20, to cutting-clamping terminals 44 wherein the cables have insulator sheaths 21 which are relatively thick in comparison with the diameters of their cores 22. A precutting device 11 is provided having a lever 23 of U-shaped cross-sectional outline which is mounted on the shank 14 of an applying hand tool. The inner sides 33 of the lateral walls 56, 57 of the U-shaped lever 23 carry arcuate knives 12, 13. These knives remove, at a predetermined contact area 37 of a cable, two portions 34, 35 of insulating material from the insulating shell 21 so that the contemplated contact area can be more readily forced into the slot 45 of a cutting-clamping terminal 44. The means on the shank for forcing the cable core 22 into the slot 45 comprises insertion ribs 32 at one end of the applying hand tool the other end of which is adjacent to a hollow arcuate handle 15 (FIG. 2).

Abstract: A multipolar plug has a two-piece plastic housing which partially confines one or more one-piece synthetic plastic inserts each of which has a centrally located retaining section removably engaging the housing and a two-part second section. One part of the second section is confined in the housing, and the other part constitutes one or more prongs which can enter a receptacle to engage their contact members with complementary contact members in the receptacle. Each second section carries two or four discrete strip-shaped contact members which are blanked from sheet metal and have central portions fully embedded in the respective retaining section. Each contact member further includes a second portion which is partially embedded in the first part of the respective second section, and a third portion which is partially embedded in the second part of the respective second section. The contact members are disposed, either singly or in pairs, at the opposite sides of the respective second section.

Abstract: A heat protection device for overvoltage terminal block arrester magazines having with two-way arresters or with button arresters. According to the present invention, an S-shaped clip spring or an L-shaped clip spring is inserted in a button arrester of the 6.times.6-type or the 6.times.8-type. The clip provides one leg of the protection device having a solder preform and a switch contact to complete the circuit. In case of an overvoltage, the arc developed in the arrester causes the solder preform to melt off during an extended application of heat arising from the arrester, activating the switch contact and short-circuiting the leg of the arrester.
