Patent EP-0321124-A3 (EP)
Title: Speed control means and apparatus for a repeatable material processing apparatus
IPC: D01H1/34
Filed: 1988-12-01
Abstract: The invention provides a means of controlling the speed 
of operation of a material processing apparatus, such as a 
ring spinning machine in a textile mill. The purpose of the 
invention is to allow high speed processing, whilst maintaining 
a high quality product. In the case of ring spinning for instance, 
the object is to reduce the incidence of yarn breakages.  
     The method in accordance with the invention includes 
controlling the speed of operation during a total time for 
processing a finite quantity of the material, and including 
the use of an automatic control apparatus preset to change the 
speed of the driving motor in a series of very small increments 
throughout a speed change time which is a predetermined 
percentage of the total time, between two speeds, one of which 
is a predetermined optimum operating speed and the other of 
which is a predetermined percentage of the operating speed. 
The essence of the invention is the selection of percentages of 
the operating speed and the total processing time for controlling 
the point from which the speed change is effected up to the 
operating speed or down to which the speed change is effected 
from the operating speed.

contacts are received include anti-overstress partitions that 
limit the travel of the curved-beam-spring contacts to within 
their elastic region, and that provide reaction bearings against 
which the curved-beam-spring of the contacts react to bear against 
the J-leads of the PLCC. Both the cover and the body are low 
material cost and production cost single-piece items readily 
fabricated by injection molding, metal cutting and stamping 
operations.

Title: Device for fastening an article to a wall
IPC: A47K10/10
Filed: 1989-01-12
Abstract: To simplify the assembly of articles to be fastened to a wall, such as for example sanitary fittings, with two or more holding parts 4 fitted with screw holes, it is proposed that an adhesive strip 4 or the like, coated on both sides and covering the screw holes 42 and having markings 51 corresponding to the screw holes 42 is arranged on the wall-side contact surface 41 of each holder 4, the adhesive effect of the wall-side coating of said adhesive strip being substantially stronger than the adhesive effect of the fastening-side coating. For the assembly, an article of this type is pressed with its holding parts on the previously determined place on a wall or another fastening base and then removed again. Due to the stronger adhesive effect of the wall-side coating, the adhesive strip 5 remains on the wall. The bore holes are introduced through the adhesive strips 5 into the wall or the like situated below it. <IMAGE>

Title: Rotorfilterpress with chamberflow
IPC: B01D25/12
Filed: 1989-04-13
Abstract: In the rotary filter press, a rotor 4 having fins 5 is provided and the leading edges 13 of the fins 5 brush over a leading edge surface, in which a stator 6 supports a filter medium 7, which with a leading surface 12 lies opposite the leading edge surface 13 at a distance, and in which a substance between filter medium 7 and rotor 4 forms a closed circular flow pattern, and the filter medium 7 is maintained free from sediment. It is required that the freedom from sedimentation is maintained over an extended period of time. This is achieved by changing the distance between the leading surface 12 of the filter medium 7 and the leading edge surface 13 of the rotor 4 in a radial direction so that eddies 11 are formed in the circular flow pattern. Changing the distance increases the time period during which the filter medium is free from sediment and increases the filling level possible in the chamber for material to be filtered. <IMAGE>

Abstract: In a switching power supply for a television 
apparatus, a switching stage (SW1) is coupled to a source 
(31) of DC input voltage and to an energy storage 
inductance (L1) for developing a source (VO) of DC supply 
voltage. Operation of the switching stage generates a 
switched waveform voltage in the inductance (L1). The 
primary winding (W1) of a flyback transformer (T1) is 
coupled to and energized by the DC supply voltage (VO). A 
second winding (W2) of the flyback transformer is coupled 
to the inductance (L1) and provides a magnetic path, via 
the flyback transformer (T1), for energy to circulate 
between the source of DC supply voltage and the energy 
storage inductance (L1). An auxiliary winding (L2) is 
magnetically coupled to the inductance (L1) and to a load 
circuit (46), such as a high power audio stage, for 
transferring at least a portion of the circulating energy 
to the load circuit. Additionally, the flyback transformer 
(T1) may be used to directly transfer (through W4) energy 
to the load circuit (46).

Title: Improvements to the catalyzed oxidation of bayer liquor organics
IPC: C01F7/476
Filed: 1990-02-14
Abstract: An improved method for oxidizing the organic carbon 
substances in the caustic aluminate liquor of the Bayer process 
under the influence of metal catalyst ions, whereby there is no 
net build-up of sodium oxalate or benzene carboxylates in the 
oxidized liquor. The method comprises the steps of heating the 
liquor to a temperature of 270-280°C; supplying, in an oxygen-­
containing gas, no more than the stoichiometric amount of 
oxygen necessary for the conversion of the organic carbon 
content of the liquor to inorganic carbon; rapidly oxidizing 
the low molecular weight organic substances present in the 
liquor, such as sodium acetate, thereby effecting a rapid rise 
in temperature into the range 290-320°C; holding the liquor 
under agitation within the temperature range 290°-320°C until 
an organic oxidation efficiency not exceeding 95% is achieved; 
rapidly cooling the oxidized liquor to conditions of at­
mospheric pressure at a temperature of approximately 95°C and 
recovering the metal catalyst ions along with precipitated 
aluminum hydroxide. The improved method has particular 
relevance to processes uaing a tube reactor and copper or a 
transition metal as the source of metal catalyst ions.
