Patent DE-3728587-A1 (DE)
Inventor: CASPERS JOHANNES
IPC: G11B17/22
Filed: 1987-08-27
Abstract: CD players in which such a device can be moved up and down in the manner of an elevator, for example by means of a drive comprising a spindle, a rack and gearwheels, or a slotted link on each side, are known. It is disadvantageous that many expensive small parts are required, such as for example gearwheels, spindles, worm wheels, racks, slotted links etc., which not only take up considerable space but also cause disturbing noises during operation. In order to reduce the expenditure on components, at the same time save space and reduce the disturbing noises, a drive is provided only on one side of the device (6), whereas on the side opposite the drive there is provided a spring (3) for supporting the device (6). CD players, video-disc players, draw-disc players, magneto-optical equipment. <IMAGE>

Title: Flow volume counter for liquid media
Inventor: ANDERSEN NIELS THORUP
IPC: G01F1/66
Filed: 1987-10-13
Abstract: The flow volume counter comprises a measured value transmitter (1) for liquid media having an ultrasonic measuring path in a measuring tube (2), an oscillator (15) for the generation of ultrasonic waves by means of measuring transducers (6, 7) during a transmission phase of a measuring cycle, a measuring element (10) for measuring the phase difference  alpha  caused by the transit time difference and existing between the DOWN-receiver signal (29) generated in the measuring transducer (7) in the received phase by the sound wave accelerated by the flow and the UP-receiver signal (28) generated in the measuring transducer (7) by the sound wave delayed by the flow, and a counting device (12) with an indicator device (13). In the measuring element (10), the UP-receiver signal (28) is additionally delayed by a constant phase difference  delta  alpha , before the phase difference  alpha  +  delta alpha  is measured by means of sampling pulses (34). The zero-point displacement  GAMMA  effected thereby corrects the indicator device (13) after each measurement cycle. Flows in both directions are correctly detected. <IMAGE>

Title: Fastening arrangement for a rod-shaped part
Inventor: SYKORA VLADIMIR
IPC: F16B21/00
Filed: 1987-12-09
Abstract: The invention relates to a fastening arrangement for a rod-shaped part, in the case of which the said rod-shaped part (2) is introduced, by means of its two ends (2a and 2b) which each exhibit at least one flattening (6 and 7 respectively) running transversely to the longitudinal axis (5) of the part (2), into two equiaxially aligned, mutually opposite, slot-shaped receiving means (4) and is secured in said receiving means (4) against rotation and falling out. The rod-shaped part is well secured, even in non-elastic materials, in that, when the rod-shaped part (2) is in a state in which it is not inserted into the receiving means (4), the flattening (6 or 7) of one end (2a) is rotated through a certain angle (a) in the circumferential direction of the rod-shaped part (2) with respect to the flattening (6 or 7) of the other end (2b). <IMAGE>
Patent DE-3803840-A1 (DE)
Title: Photometer
Inventor: DICKEN WILFRIED DIPL PHYS
IPC: G01J1/16
Filed: 1988-02-09
Abstract: The invention relates to a photometer, in particular for the measurement or control of light intensities in plasma processes. In this case, the light to be measured or controlled is fed via an optical fibre (23) to a light chopper (26) and compared, displaced in time, with a second light source, which is, for example, a reference light source (29) having pulsed light. This comparison can be achieved by means of quotient formation and be carried out by means of an analog divider circuit (34, 35, 43, 45). This divider circuit (34, 35, 43, 45) makes it possible to process a signal with high accuracy over four decades, referred to the amplitude of the signal. The output signal obtained by the proportioning is used for the control of a process in which the light brightness of one or more spectral lines is influenced. <IMAGE>

Title: Two-part piston, particularly for internal combustion engines
Inventor: SCHELLING HELMUT
IPC: F02F3/00
Filed: 1988-05-20
Abstract: In the case of a two-part piston (1) for internal combustion engines, consisting of a top part (2) and a bottom part (3) which are connected to one another only via a gudgeon pin (4), the intention is that the side forces emanating from the connecting rod (17) should be taken exclusively by the piston skirt (15) serving to guide the piston (1) in the cylinder and should not have a deleterious effect on the top part (2) of the piston. In order to achieve this, there is an integrally formed radial rib (18) on the inside of the lower part of the piston skirt (15), in the region of the hole (16) through it, and, with the piston installed, this rib comes to rest against the connecting rod (17). <IMAGE>

Title: Process for the preparation of aminoaryl-ss-sulphatoethylsulphone compounds
Inventor: RUPP WALTER DIPL ING
IPC: C07C317/18
Filed: 1988-11-29
Abstract: Aminoaryl-ss-sulphatoethylsulphone compounds such as, for example, 4-(ss-sulphatoethylsulphonyl)aniline, can be prepared rapidly and easily from their corresponding ss-hydroxyethylsulphone compounds by sulphation by spraying a solution or suspension or paste of this aminoaryl-ss-hydroxyethylsulphone compound or its acylamino compound into sulphuric acid or aqueous sulphuric acid in a hot inert gas stream of a convection dryer. In this process, the drying, esterification reaction and the hydrolysis of an acylamino group which may be present take place synchronously. The sulphato compound is preferably obtained as granules.
