Abstract: In an ink jet printing head which comprises several nozzles (18), each of which having associated with it an essentially oppositely situated pressure chamber (2), there are provided at least two supporting sections (1,7) which are linked in a stack-like manner opposite the nozzles and on which the pressure chambers are distributed in a staggered manner. The jet nozzle ducts (6) which emerge from the pressure chambers on the supporting section (7) remote from the nozzles and which lead to the nozzles are guided between the pressure chambers on the supporting section (1) which is nearer with respect to the nozzles (FIG. 6). According to a method of manufacturing such an ink jet printing head, first the supporting sections (1,7) with the pressure chambers (2) are individually finished after which they are linked in a stack-like manner and provided in a mould with an adapter piece (15) in which the nozzle ducts (6) emerging from the pressure chambers continue into further nozzle ducts (28) leading to the nozzles (18) (FIG. 6).

Abstract: An electromechanical time switch for parked-vehicle heating systems in motor vehicles is proposed, in the case of which a control shaft is caused to rotate by a drive shaft (which surrounds it concentrically) and drives a clock hand, the various switching functions being achieved by axial displacement of the control shaft and hence operation of various contacts. This axial displacement is achieved using a sampling element which is moved along a stationary control cam while the control shaft is rotating. A special switching position provides that a spring latches in a circumferential groove on the control shaft, which decouples the sampling element from the control cam, so that the time switch is blocked after one complete switching process.

Abstract: Pure ferro-alloy metals are isolated from fine-grained crude oxidic mineral products by reduction melting and subsequent anodic liberation of the iron. The reduction melting is performed in a plasma-heated furnace into which the fine-grained oxide material is blown together with carbon powder and circulating exhaust gas, extremely over-heated in a plasma generator, the quantity of carbon powder being dosed so that most of the alloy metal(s) is converted to carbides during the reduction. After electrolysis, the anode residue will consist primarily of alloy metal carbides from which the metal can be recovered by known methods.

Abstract: In a method and an apparatus for separating water and solid particles from an oil, the oil is supplied to a treatment step in which the water in the oil is evaporated and components dissolved in the water are precipitated as solid particles. In order that each separate water element in the oil shall have a short distance to reach an outer surface of the oil, said treatment step preferably takes place when the oil is spread out, either in small drops and/or a thin layer. After this treatment step and with the treated oil separated from the water vapour, a particle separation from the oil takes place not only of particles formed by the precipitation but also of other particles in the oil, if any.

Abstract: Hollow flag-poles (1) of metal or plastic are provided with a hole at the upper end allowing a rope (11) to be located inside the flag-pole (1) with the exception of the end of the rope which is secured to the attachment at the top corner of a flag (13). The attachment at the lower corner of the flag (13) is connected by a weight (14) to a loop (15) around the flag-pole (1). The other end of the rope (11) is connected to a reeling unit (16) arranged inside the flag-pole (1) at a suitable level from the ground to be operated manually. The object of the invention is to eliminate the need for a hole to be made for the rope at the top end of the flag-pole (1) and to prevent a flag (12) from becoming entangled once it has been hoisted. This is achieved by the use of an end-piece consisting of two units (2 and 3) arranged one after the other and preferably pivotable in relation to each other, one unit (3) having an aperture (10) to receive a rope (11) in communication with a passage (5) arranged inside the two units (2 and 3) for the rope (11) coming from said aperture (10).

Abstract: The melt is treated in a treatment chamber (4, 5) with an agent (2a) which promotes the formation of spheroidal or vermicular graphite, and is then introduced into a mould cavity (8). The agent (2a) comprises an alloy based on magnesium and/or rare earth metals, and is placed in a recess (2) in the base of the treatment chamber. Above the recess (2) there is arranged a dividing element (3) which acts as a flow resistance and ensures an intense reaction of the melt with the alloy. During the pouring-in process, a pouring gate (7), which communicates the treatment chamber with the mould cavity (8), is closed by means of a plug (6), whereby the melt is dammed-up for a short time before the plug (6) is opened thereby allowing the mould cavity (8) to be filled with treated melt. Thus, the melt is in contact with the agent for a sufficient period until the necessary reaction time has expired and the reaction products separate and a complete blending of the melt is achieved, prior to introduction of the melt into the mould cavity. <IMAGE>
