Abstract: In the filtering apparatus for an extrusion machine, a stream of heat-softened plastic material arrives via a flow conduit in a filter housing at an outlet, and thereby permeates replaceable filter means which are carried by a slide which is temporarily slid out of the stream of plastic material. For this, the slide comprises two chambers, forming flow conduit sections and arranged spaced in tandem in the direction of displacement, both of which are closed by filter plates. The slow conduit sections being, at a specified position of the slide in the filter housing internally in flow connection via, in each case, a port, with the outlet conduit in the filter housing and, externally via the filter plates, with the inlet conduit or with a backflow conduit in the filter housing.

To hold the handset or operating handset, a handset rest is used. The radio section is connected to the spatially separate system parts via connecting cables. The connecting cables are usually specially adapted to the model variant provided in each case. As basic equipment of a motor vehicle, a cable exists between the location of installation for a radio section in the boot space and the interior space of the vehicle. 
<??>The mobile radio system is to be designed in such a manner that fitting and refitting with different model variants is possible in the simplest and most inexpensive manner. 
<??>For this purpose, operating device and handset rest can be arbitrarily connected to one another and to the radio section.

Abstract: Gasified beverage frothing apparatus has a dip tube (5) for insertion into a gasified beverage (33) which is to be frothed. A piston (7) in the tube (5) forms a chamber (9) which communicates with the beverage through a restricted orifice (30) and a port (31) having a non-return valve (32). On expansion of chamber (9), beverage is drawn in through the port (31) and on contraction of the chamber beverage is expelled through orifice (30) to be subjected to cavitation so that gas in solution in the beverage is liberated to form a head of froth. The piston (7) is biased by spring (14) to contract the chamber (9). Chamber (9) is expanded against spring (14) by manual rotation of a multi-lobe cam (15). As cam (15) rotates a cam follower (17) linked to the piston (7) is displaced on the cam to expand the chamber (9) until the follower (17) moves over a cam lobe to permit the chamber (9) to contract solely under the pressure of spring (14). Cam (15) is rotated by arcuate displacement of a lever (22) coupled thereto through a one-way drive system (25, 26) so that successive arcuate reciprocation of the lever successively rotates the cam for repeated expansions and contractions of the chamber (9).

Abstract: The bearing assembly (10) is of the hydrodynamic type, for use as a spindle. It includes spaced journals mounted on a shaft (12) for rotation therewith. The housing (20) includes spaced support bearings (16, 18) cooperating with the journals to form a gas gap (16c, 18c) therebetween. The support bearings (16, 18) are resiliently mounted by flexible spring seal elements (23) in the housing for axial, radial and angular movement. The elements (23) are self-energizing and comprised of relatively low coefficient of friction materials to reduce the friction of the system thus allowing rapid adjustment of the bearing (16 or 18) in response to loads on the shaft (12). Various details are described with respect to the various structures illustrated, including the details of an air bearing spindle assembly of relatively light weight and capable of operating at speeds in excess of 100,000 RPM.

Abstract: A multi-echo magnetic resonance imaging sequence is implemented such that a radio frequency receiver (34) receives magnetic resonance echoes. The resonance data received during each echo are digitized and the resultant echo data are stored in a corresponding echo memory (40,42). The locations of the data within the memories are brought into registration by centering means (52) such that corresponding data in each memory (40,42) is disposed at the same memory address. Because data from later echoes tends to be weaker or at a lower magnitude, the magnitude of the data stored in each memory (40,42) is normalized by normalizing means (60). The phase of the data in each memory (40,42) is brought into coordination by a zero order phase correction means (70). A high pass filter (84) and a complementary low pass filter (86) separate complementary portions of the data from the memories (40,42). The separated portions are combined into a single synthesized data set for storage in a memory (82). The synthesized data are Fourier transformed by two dimensional Fourier transform means (100) to produce a synthetic image which has selected characteristics of an early echo image, e.g. high resolution, and selected characteristics of a late echo image, e.g. good T2 contrast. In this manner, the synthetic image has properties or characteristics which render it more diagnostically valuable than either an early or a late echo image.

Abstract: It is an object to provide a recycle chromatograph with supercritical fluid mobile phase for separating a sample into components by recycling a mobile phase which includes modifier solvent for the purpose of taking a desired component. 
     It is structured in such a manner that a recycling pump (10), a column (14), a detector (16), and a three-way valve (18) are connected in a sequential order as described above to form a closed loop which acts as a recycle flow line. A back-pressure regulator (20) is connected to the remainder port (C) of this three-way valve (18), and a mobile phase supplying device (30, 38, 30A, 38A, 48) for supplying the mobile phase under a predetermined pressure is connected to a flow line between the three-way valve (18) and the recycling pump (10). 
     By means of this mobile phase supplying device and the recycle closed loop (the column pressure drop Δ p)/(column plate number) can be reduced, whereupon the column effective plate number can be increased. Thus, a sufficient resolution rate for fractionating a component can be obtained after appropriate recycling times. 
     Furthermore, by combining the mobile phase supplying device (30, 38, 30A, 38A, 48) and the back-pressure regulator (20), the internal pressures in the column and   the detector can be kept above the critical pressure even if unnecessary components are being removed or a necessary component is being fractionated. As a result of which fractionation can be performed.

Abstract: The previous processes for obtaining desensitised aliphatic diperoxydicarboxylic acids using sodium sulphate intrinsic to the process are difficult in terms of safety because of the production of sodium sulphate in the presence of the diperoxydicarboxylic acid and are only controllable with losses; impurities such as heavy metals must additionally be virtually completely removed in a complicated manner by means of the sodium sulphate-containing waste liquors produced during the desensitisation in order not to impair the stability of the products. 
<??>The new process should not have the disadvantages mentioned. 
<??>To this end, a new process is proposed that yields, on the basis of process sodium sulphate, improved diperoxydicarboxylic acid granules which do not have the abovementioned disadvantages. 
<??>On the basis of process sodium sulphate, improved diperoxy- dicarboxylic acids are obtained in a safe process and have a good chemical stability in spite of a high content of impurities, safe handling ability, low bulk weights and high resistance to abrasion.

Abstract: In sealing rings there is the problem that the sealing portion with the sealing lip is sometimes overturned because it is pushed onto the shaft incorrectly. This is often not noticed during assembly. The sealing ring is therefore to be designed so that it can be ascertained with absolute certainty whether it has been fitted incorrectly. At least one passage is provided on the sealing portion of the sealing ring. If this sealing ring is fitted incorrectly and the sealing portion thereby overturned, the sealing ring does not bear sealingly over its circumference against the shaft, but is at a distance from the shaft in the region of the passage. In a subsequent tightness test by means of compressed air, the latter can flow through this passage, and therefore the incorrect fitting of the sealing ring can be detected reliably. The sealing ring can be used for sealing off shafts or stands. <IMAGE>
