Patent DE-3628455-A1 (DE)
Title: Apparatus for separating off solid contaminants from liquids
Inventor: ANTONI HERBERT
IPC: B01D29/90
Filed: 1986-08-21
Abstract: Separating off solid contaminants from liquids in the case of relatively small amounts to be filtered in the continuous flow process, for example from lubrication oil of an internal combustion engine, is performed by pumping the liquid through a vessel which contains a filter material. A disadvantage in this case is that the coarse and the fine dirt particles are indiscriminately retained by one and the same filter material. As a result, the coarse particles block the pores, so that the filter action falls away very rapidly. The filter apparatus according to the invention prevents this disadvantage in that, in a cylindrical space (1), for example in a cylindrical vessel, a cylindrical hollow body (6) of filter material is situated centrally, is rotatable about its longitudinal axis and has an annular intermediate space (5) as spacing to the wall (1'). The feed (14) of the contaminated liquid proceeds tangentially into the annular space (5) between the wall (1') and the cylindrical hollow body (6). The outflow (13) of the purified liquid proceeds from the interior (15) of the cylindrical hollow body (6) (Fig. 2). <IMAGE>

Inventor: SCHEEL HELMUT DIPL ING
IPC: C22C21/00
Filed: 1987-04-28
Abstract: 1. Support material and aluminium planographic printing plate, and process for its manufacture. 
<??>2.1 Previously, pure aluminium or manganese-containing alloys have been used as support material for planographic printing plates with a baked photo-layer. Such alloys have an essentially higher thermal stability than pure aluminium but during electro-chemical roughening in HCl or HNO3, dark surface colorations and different grain structures appear which have an adverse effect on the technical copying properties or their general ability to respond to roughening treatment. The object is to find a support material which has a pale uniform surface after the roughening treatment, a general ability to respond to roughening treatment and simutaneously high stability under baking conditions. 
<??>2.2 A material with a fine precipitation micro-structure (degree of dispersion D < 50 phases/ mu m<3>) is produced from an aluminium alloy containing 0.2-0.6% Fe, < 1% Mn, < 0.25% Si and Cu under adherence to particular conditions during the heating and shaping. The ratio of the dispersed phases AlMnSi:AlFe:AlMn lies between 1:1:2 and 1:1:3. Because of dissolved Fe and Mn as well as the fine precipitations, this material possesses a high thermal stability. Since the very fine Mn-containing phases are present only in small proportions, the surface quality necessary for planographic printing plates is achieved by the electro-chemical roughening in HCl as well as in HNO3. 
<??>2.3 Manufacture of aluminium planographic printing plates.

Patent DE-3718551-A1 (DE)
Title: Liquid-ring expansion engine with condensate return
Inventor: HETTENHAUSEN WILHELM DIPL ING
IPC: F01C7/00
Filed: 1987-06-03
Abstract: The invention concerns a method employing a liquid-ring expansion engine to convert the pressure energy of compressed vapours into motive energy. At the same time, the forces of the rotating liquid ring, which consists of gas condensate, are to be used to feed condensate continuously to the vapour generator in the sense of thermodynamic cycles. With such an expansion engine, two functions of the cycle, letting gas expand and pressing condensate into the vapour generator, can be performed by a unit that is simple to manufacture and long-lived. No pump is needed. High-grade mechanical energy can be obtained with the expansion engine and two heat exchangers (for vaporisation and condensation of the working medium) without disadvantages in the energy conversion, for example on the basis of the organic Rankine cycle. In this device, the functions of an expansion engine and a boiler feed pump overlap. The unit is simple to manufacture and long-lived. <IMAGE>

Patent DE-3723877-A1 (DE)
Inventor: SCHULMEYER HANNS-LUDWIG DIPL I
IPC: B61L1/18
Filed: 1987-07-18
Abstract: A circuit arrangement is disclosed which makes it possible to suppress interference voltages of identical frequency in a track circuit fed with AC current and equipped with a phase-sensitive threshold value switch (RG). The operating voltage (US) for the track circuit, from which the reference voltage for the phase-sensitive threshold value switch is also derived, is taken for this purpose from a controllable inverse rectifier (W) which is driven in such a way that its frequency is subject to constant slow change in a predetermined narrow range. In order to also suppress interference voltages which are present over a long time and whose frequency corresponds exactly to the centre frequency of the predetermined frequency range, the frequency range is shifted at specific time intervals. <IMAGE>

IPC: D21B1/32
Filed: 1988-02-10
Abstract: For the removal of sticky contaminants, so-called stickies, during the preparation of (stock from) waste paper, the stock having already been pulped and cleaned in various devices, it is proposed to convey the stock in a very thin layer (1), in the range 10 to 50 g/m<2>, between a wire (2) and a cylinder (3), wherein it is optionally washed and thickened. In so doing, essentially all of the stickies in the layer (1) are brought into contact with the cylinder surace (4), in order to remain adhered thereto. After the removal of the stock web (1) from the cylinder (3), the sticky-layer (5) produced on the surface (4) is removed from the surface (4), at least down to a residual layer (6), from the rotating cylinder (3). A known washing and thickening machine, which has been provided with the expedient pressing and cleaning devices at low cost, is well suited to carrying out the method. <IMAGE>

The end pieces (16, 22) are coupled to in each case one servomotor (10 and 18, respectively). The one servomotor effects, via a gearing, adjustment with sufficient torque, while the second servomotor is directly connected to the end piece and effects compensation of residual errors. <IMAGE>
