Abstract: A control circuit for controlling a known active harmonic filter operating as a step-up converter in a power supply with sinusoidal network current input and a power factor of almost unity. The step-up converter comprises: a main rectifier, a storage inductance (LS), a cross-connected high-speed transistor (TQ), a diode (D1) and a power storage capacitor (CL). The high-speed transistor (TQ) is controlled by a first threshold switch (STc) whose input is controlled by a control capacitor (C12) coupled to receive a signal representative of instantaneous rectified d.c. output voltage (UE), instantaneous power output voltage (Uo) and a signal representative of the charge state of the inductance. The inductance charge signal is obtained from a voltage jump (ringing voltage) between the inductance and the diode (D1) by sensing a flank of an oscillation voltage occurring at the diode by a RC circuit (R8, C10), which triggers a second threshold switch (STa) to control charge reversal and recharge of the capacitor (C12), thus determining the time instants of operation of the first threshold switch to control the cross-connected electronic switch (TQ) to conduction, and hence re-storing of electrical energy in the inductance.

Abstract: For the fermentative preparation of polysaccharides, in particular xanthane, water, production medium (sugars, nutrient salts), and an inoculation material of a suitable aerobic bacterium are mixed in a reactor as reaction components, the production medium being exposed to fermentation while an oxygen-containing gas is being supplied. The object is to avoid the usual low yield of such a process and to reject an expensive and sensitive alternative construction (circulation tube). According to the invention, the reaction components are introduced into a reactor vessel in a circulating flow by means of pumping means, which circulating flow comprises a rising flow and a descending flow which are separated from each other by one or more partitions disposed in the reactor vessel. The mixing is brought about because the rising flow and/or the descending flow is passed essentially in the form of a plug flow through one or more static in-line mixers.

Abstract: A Venetian blind (1) is accommodated within the sealed interspace (5) defined by two glass surfaces (7,8) of a glass-box (6), the glass surfaces being spaced apart by an aluminum frame (4) which contains a molecular sieve (10). The Venetian blind is provided with control members (12-37) which allow adjustment of packing and/or inclination of its blades (2) from outside the glass-box (6) without altering the seal, and therefore the functionality, of the same. Operation from the outside of the control members inside the glass-box is achieved, for each adjustment, by magnetic coupling, through one of the glass surfaces of the glass-box, between a first magnet (22,32), positioned inside the glass-box and directly connected to the respective control system, and a second external magnet (23,35).

Abstract: A split tire mold having a tread ring in which provision is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-wedge-shaped" arch-vents which provide passage for trapped air above each tread block of the tread as it is moved against the inner surface of the tread ring. The shape of the arch-vent passages and the angulation of the wedges is critical to the effectiveness of the arch-vent which forms an arch-vent bridge of cured rubber in a cured tire. The configuration of the bridge allows a cured tire to be easily removed from the mold cavity without leaving a broken-off piece of the rubber bridge to plug the arch-vents. This arch-vent design leaves unobtrusive flat-sided, narrow wedge-shaped pieces of rubber as the arch-vent stubs, tapered in two directions. The arch-vent stubs, when viewed in the radial direction towards the center of the tire, are so unobtrusive as to be cosmetically acceptable in a finished tire. The upper surface of the arch-vent is close to the inner surface of the tread ring and essentially horizontal, while the lower surface of each arch-vent is inclined at an angle in the range from 30 DEG -50 DEG  to the horizontal plane, but in opposite directions. An angle in this range provides surprising strength in the base area of the arch-vent stub so that, upon stripping the tire from the mold, the arch-vent bridge of cured rubber breaks cleanly and reliably at the narrowest and weakest point in the bridge.
