Abstract: The cover (16) provides an even temperature distribution and a nearly uniform moisture gradient. This reduces the energy consumed by the drying process and allows use of a higher temperature in the timber than has been used for conventional drying. The timber stock (14) is disposed on a carrier (13) in a treatment room (10) which is irradiated by a microwave source (11). The internal walls provide high reflectivity to microwave radiation and prevent leakage of microwave energy from the room. To avoid field distortions by the metal wheels of the carrier they are separated from the stacked timber by a distance equal to two wavelengths of the microwave radiation in a vacuum. Air is circulated by a system (12) including a ventilator (18) producing low circulation speed and a cooling element (17) to condense moisture removed from the treatment room.

Abstract: A control arrangement for use in a hydraulic braking system equipped with an antiskid control device and an auxiliary energy source and including a master cylinder device which is operated in dependence on the travel of a brake pedal, includes normally open separating valves in braking conduits to the wheel brake actuating cylinders, which close during antiskid control operation, provided that auxiliary energy is available. An auxiliary supply conduit supplies the auxiliary energy to the wheel brake actuating cylinders so that the latter can be operated in a dynamic manner. A normally closed return valve is interposed in the return conduit from the respective wheel brake actuating cylinders and can be opened, either directly or indirectly, by the auxiliary energy during the antiskid control operation, so that the pressure from the wheel brake operating cylinder to be controlled can be relieved to the low-pressure supply reservoir while rendering static operation of the wheel brake actuating cylinders possible in its normal closed position assumed when no antiskid control action is needed. The pressure of the auxiliary energy hydraulic fluid can be generated by a hydraulic pump which is operated only during the antiskid control action, or the auxiliary energy supply system can be operated on a continuous basis, in which case the auxiliary hydraulic fluid is supplied to the hydraulic braking circuit only when the need for an antiskid control action arises.

Abstract: The invention relates to a time sequence control for electronically controlled breathing apparatus, using integrated circuits of sensor technology, in which breathing rate and ratio of breathing time are to be set in a calibrated manner and varied independently of one another. It essentially consists of two shift register chains, known per se, which are in each case formed by connecting together two 3-bit counters and two binary 1-of-8 decoders. The clock inputs C of the 3-bit counters of the first shift register chain are connected to a squarewave generator via a frequency divider and are acted upon by a clock signal fT/1. Various clock frequencies fT/2 are generated for the second shift register chain by variable resetting. A flip flop is connected to the output of the second shift register chain in such a manner that it is set by the first output pulse and reset by a later variable output pulse. The last output pulse resets the 3-bit counters of the second shift register chain so that a breathing time ratio can be set independently.

Abstract: A new process for the preparation of 6-deoxyanthracyclinones of general formula I:   <IMAGE> I  wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using 1,2,3,6-tetrahydro-phthalate as starting material. The obtained racemic mixture of the compounds of formula I, if desired, can be submitted to optical resolution by the conventional method of conversion to diastereomeric derivatives using a chiral resolving agent. Alternatively, the racemic mixture can be used as such for the condensation with a suitably protected halosugar derivative to obtain alpha glycosidic derivatives of formula XV:    <IMAGE> XV  wherein R1 represents a hydrogen atom or a hydroxy group, one of R2 and R3 represents a hydrogen atom, the other of R2 and R3 represents a hydrogen atom or a hydroxy group and X is a hydrogen atom or a trifluoro acetyl group. The N-trifluoroacetyl 7S:9S and 7R:9R derivatives of the  alpha -glycosides of formula XV can be separated by chromatography on silica gel to obtain, after mild alkaline hydrolisis the wanted 7S:9S  alpha -glycosides (R1=H) as free bases and can eventually be transformed into their corresponding doxorubicin derivatives (R1=OH) by known procedures.
