IPC: D04B19/00
Filed: 1988-02-19
Abstract: A method of preventing the edge of knitted fabric from unravelling comprises the steps of knitting at least two courses (12) forming the edge of the knitted fabric with a double yarn consisting of a melting yarn (14) and a heat-shrinkable yarn (15) and subjecting the knitted fabric to heat treatment at a temperature at which the melting yarn melts and the heat-shrinkable yarn shrinks but does not melt. A border course (10) of water-soluble yarn (17) may be included. The course (12) may be knitted with smaller loops than the fabric courses (1). <IMAGE>

Title: Mechanically operated floating-calliper disc brake
Inventor: NEITZ WOLFGANG DIPL ING
IPC: F16D65/56
Filed: 1988-04-28
Abstract: The invention discloses an automatic adjusting device for a mechanically operated floating-calliper disc brake. The mechanically operated device for displacing the floating calliper relative to the brake disc consists of an oblique-path expander which has an operating shaft. The adjusting device comprises an adjusting nut which is coupled to the operating shaft via a ratchet mechanism which is operative when the operating shaft is rotated in the operating direction. This ratchet mechanism is designed as a friction ratchet mechanism which, in the locking direction, transmits torques only up to a certain upper limit for the clearance adjustment and slips when this limiting torque is exceeded.

Patent DE-3828110-A1 (DE)
Title: Eddy-current coupling
Inventor: FRUTTIGER WILHELM
IPC: H02K49/04
Filed: 1988-08-18
Abstract: The invention relates to an eddy-current coupling having a drive shaft with a permanent magnet and a driven shaft with an eddy-current disc. As long as the eddy-current disc, and therefore the driven shaft, has not yet reached its normal operating rotational speed, high eddy currents are formed in the eddy-current disc, which leads to heating. This heat is at least partly given off to a fluid having a high coefficient of thermal expansion, which fluid expands as a result of the heat received and displaces the eddy-current disc axially relative to the permanent magnet, which increases the separation between these two parts. As soon as the temperature, and therefore also the expansion of the fluid, falls, the eddy-current disc is returned to its initial position by means of a return spring.

Patent DE-3833054-A1 (DE)
Inventor: WEHLAND PETER
IPC: B03B7/00
Filed: 1988-09-29
Abstract: Slurry with fine coal grain particles, from the sedimentation stage of coal washery plant, is further treated to extract useful products. The slurry is mixed with water in rotary drum (8) and then classified to remove particles above 3 mms (17) in trommel screen (13). Particles below 3 mms are passed from screen 13 to separator (20) which separates particles into two fractions, 0.5mm to 3mm and below 0.5mm. The fine grains below 0.5mm are processed in a flotation apparatus (44, 48) and the particles from 0.5 to 3mm are processed in helical gravity separators (25, 35). Similar fractions thereby obtained are brought together for de-watering and the plant provides fine grain washed coal with 10.12% ash content and fine grain dirt with an ash content of about 80%. The fine grain coal can be burned while the fine grain dirt can be used for making building blocks. The water used in the plant is largely recycled. <IMAGE>

Title: Method and device for the determination of the angle of inclination of a measuring container for the gravimetric determination of mass and delimitation of mass of its content
Inventor: MIETH HANS OTTO DIPL ING
IPC: G01G17/04
Filed: 1988-10-20
Abstract: The invention relates to a method and a device for the determination of the angle of inclination of a measuring container for the gravimetric determination of mass and delimitation of mass of its content. By means of a method of this type and a device for carrying it out, it is ensured, inter alia, that the determination of inclination can be carried out by the measuring container itself without having to take account of the maintenance of specific emptying conditions. This is achieved, inter alia, by weighing the measuring container 1 by means of the device 18 measuring the forces, once with and once without a known additional mass 72, the angle of inclination  alpha being determined from the difference of the two weighings (Figure 3).   <IMAGE>

Inventor: SCHAEFER JOCHEN
IPC: B60L3/10
Filed: 1989-04-21
Abstract: Described is a control system, in particular one for drive wheel slip control, in which the derivative of the measured variable is used at least jointly as a control variable. In order to avoid or reduce errors in the measured variable when forming the derivative in the region after the turning point value of the measured variable, the turning point value is stored and, after a time  DELTA T after the storage, the difference  DELTA V between the stored value and the instantaneous value of the measurement signal is continuously plotted. Each  DELTA V value is divided by a  DELTA T (period between moment of storage and measurement time) and the signal thus obtained used as the control variable.

Title: Plastic pouch for fluids partic. blood - in which integral ribs and hollows are extruded onto inner surface of tube and prevent adherence of inner pouch surfaces
Inventor: RIETIG HERBERT
IPC: B29C48/12
Filed: 1989-06-14
Abstract: A pouch manufactured in plastics, particularly PVC is used for fluid containment. The pouch consists of an extruded tube welded at the ends and which has ribs and associated hollows formed on the inner surface. The ribs have a spiral pattern for preventing pouch sides from adhering to each other. A production process uses an annular die with teeth and grooves formed on the inner circumference to create the ribs and hollows. The spiral pattern is achieved by die rotation. Extruded tube is guided from the haul off unit direct to a welding station where upper and lower pouch edges are welded. USE/ADVANTAGE - For containment of fluids, partic. blood.  Prodn. is simpler and sterilisation is easier for medical use. The ribs and hollows only exist on the inner pouch surface.

Abstract: During the production of yarn in which the winding of the yarn onto the bobbin is integrated into a spinning process the yarn is delivered continuously even during the period required for preparation for winding. The yarn is passed through a storage duct 4 by means of an air stream from blower 3 and is diverted by suction means 6. The duct outlet 7 is closed at the beginning of storage sufficiently for the yarn to build up in loops, in known manner, to form a yarn column 11. The air stream acting upon the yarn column is guided laterally from the store duct. After storage, the yarn column is worked off without residue at an elevated yarn take-off speed by the bobbin 8 and the duct outlet 7 of the store is then opened completely for free yarn passage. <IMAGE>
