Abstract: In a replaceable ribbon cartridge (12) for printers in which the ribbon (14) can be guided out of the cartridge through an exit opening (16) and at the end of a tension segment extending outside the cartridge can be reintroduced into the cartridge through an entrance opening (18), there is arranged on the cartridge (12) in the zone of the tension segment at least one deflection slide (24, 26) displaceable in a direction approximately perpendicular to the ribbon plane between a position of retraction into the cartridge (12) and an extended position deflecting the ribbon (14). Through the deflection slide or slides (24, 26), the ribbon (14) is generally spread away from the cartridge sufficiently so that upon insertion of the cartridge into the printer, it places itself around the printer head. During the last phase of insertion, the deflection slides (24, 26) are retracted, as by means of rams (56) arranged on the printer, so that during the subsequent ribbon advance, the ribbon (14) can become tensioned in its guide.

Abstract: It has been found that layers which include arsenic and/or zinc can have an adverse effect upon optoelectronic semiconductor devices such as lasers. This is reduced by treatments in which arsenic and zinc are excluded. Preferably the substrate is cooled from reaction temperature in the presence of a mixture of hydrogen and PH3 (replacing AsH3 and/or Zn(CH3)2 used to grow the final layer). Alternatively, devices having a contact layer of heavily p-type gallium indium arsenide are improved by the deposition of a protective layer of indium phosphide. This layer is removed immediately before metalisation. Even though the protective layer is not present in the final product it has a beneficial effect.

Abstract: In a conventional optical heterodyne receiver with a standard six- port fibre coupler, a loss of sensitivity occurs compared with an optical heterodyne receiver with a 90 DEG  hybrid and, furthermore, laser amplitude noise is inadequately suppressed. Therefore, according to the invention, the receiver with a six-port fibre coupler (K) is designed as a pair of balanced receivers, so that the photocurrent amplifiers connected behind the photodiodes (PD1, PD2, PD3), through suppression of the DC components in the photocurrent, receive only the differences in current between the photocurrents of in each case two photodiodes. <IMAGE>

Abstract: The invention relates to a method for the packaging of edible oil in flexible packages (1) without a risk of deformation of the packages such as occurs as the air enclosed in the packages readily dissolves in the edible oil and creates a partial vacuum in the package (1). This problem is solved in that the edible oil beforehand is saturated with nitrogen gas (N2) and that the packing operation is performed in a chamber (2) wherein a nitrogen gas atmosphere prevails. As a result of this process the sealed package (1) on the one hand will contain edible oil saturated with nitrogen, which means that the edible oil in principle is unable to absorb any more nitrogen gas, and on the other hand the gas which is enclosed in he package (1) consists of just nitrogen gas, which means that the edible oil cannot absorb and dissolve the gas which is enclosed in the package (1)

According to the invention, the portion of phosphatizing solution is introduced from below into an aeration unit (3), which is fitted with a self-aspirating aerating stirrer (4) which narrows at least in the lower region, and is aerated. When aeration is complete, the iron phosphate formed is allowed to settle, and the phosphatizing solution, with a depleted iron(II) content, is sucked upward and fed back into the bath tank (1). 
<??>In a particularly advantageous procedure, the iron phosphate sludge deposited principally in the narrowed region of the aeration unit (3) is stirred up in water with the aid of a stirrer (8) projecting into the narrowing region, but this is not carried out until several batches have undergone precipitation treatment.

Abstract: In order to switch a switch latch in a fitted installation switch, which switches off in the case of excess current, of electrical low-voltage distribution devices, especially in motor protection switches, means for manually switching off and for automatic tripping are arranged between a board and a chamber (12). For manually switching off, the switching-off force generated on a switch lever is transmitted onto a step (84) of a slide element (52) which can move in the direction of a ratchet element (44), until a ratchet lug (20) unlatches from the pivoting ratchet element (44) and is opened in a sudden manner by means of stored spring force. For automatic tripping, a trip ratchet (60) is pivoted by means of thermal or electromagnetic forces, until its tab (68) rests close to a tab (70) of a ratchet (44), which permits a pivoting movement of the ratchet (42) which is tensioned by spring force. This pivoting movement is transmitted to the ratchet element (44), as a result of which the ratchet lug (20) unlatches. The electrical contacts of the fitted installation switch are opened suddenly in the case of manual and automatic tripping. <IMAGE>
