Patent DE-3144261-A1 (DE)
Title: Process for the preparation of cinnamic acid and coumarin
Inventor: KERN RUDOLF DR
IPC: C07D311/10
Filed: 1981-11-07
Abstract: Cinnamic acid and coumarin are produced on an industrial scale in a Perkin synthesis by heating the mixture of the reactants benzaldehyde, or salicylaldehyde, with acetic anhydride and sodium acetate. This results in a yellow or brown colouration which must be removed during working-up by filtration with active carbon. The invention utilises the scientific finding technically in such a way that the first step to be carried out is an enolisation with the aid of the condensing agents such as sodium acetate together with another condensing agent such as sodium formate or their alkali metal salts of carbonates and acetates, respectively, followed by an addition of aldehyde in a constant stream with vigorous stirring, and immediately removing by distillation at the same rate the amounts of water and acetic acid formed by the effluent of the reaction.

Patent DE-3147720-A1 (DE)
Title: Method and devices for measuring the compaction pressure of a granular material
Inventor: BOENISCH DIETMAR PROF DR ING
IPC: G01L1/06
Filed: 1981-12-02
Abstract: In a method of measuring the compaction pressure especially in foundry sand moulds, pressure forces are exerted on two movable parts (2a, 4) arranged opposite one another, which pressure forces are transmitted to a deformable measuring body (5) arranged between the parts. Its deformation is a measure of the acting pressure forces. An annular gap (16) is filled with a readily flexible foam material (12) in order to prevent the ingress of sand grains and to guide the measuring piston (2a) in a swinging manner so that it can orientate itself according to the direction of the acting pressure force. Pressure load cells of this type can be used individually, but can especially be used as load-cell combinations. They enable many individual measurements to be carried out simultaneously at various points and with varying direction of action of the pressure in a closed sand ball during a single test. The measured values are recorded spontaneously in all pressure load cells and are stored there during the brief moment of compaction by the moulding machine. The pressure load cells are accurate and, on account of their simplicity and robustness, are especially suitable for use in arduous foundry practice. <IMAGE>

Title: Fan drive
Inventor: LINNIG KARL-HEINZ
IPC: F01P7/04
Filed: 1982-01-30
Abstract: A fan drive is proposed, which is used in particular for cooling internal combustion engines of motor vehicles. The fan drive is to be non-positively adjustable to the speed of the engine, by means of a magnetic clutch or the like. If the fan (32) is not engaged, it is to be set, by means of a permanent magnet (33) and a rotor (34), which rotates at the speed of the engine, to a defined windmilling speed which is less than the engine speed. The torque transmission between the drive shaft (19) and the fan (32) in this context is effected according to the eddy flow principle. <IMAGE>

Title: Guide stop on a joinery machine
Inventor: HOPMANN FERDINAND
IPC: B23Q11/00
Filed: 1982-02-18
Abstract: In joinery machines with a vertically adjustable circular saw, a machine plane and a vertically adjustable mortiser which are arranged laterally offset from one another on a work table, adjustable stops for the respective workpieces for the relevant circular saw, the machine plane and the mortiser have hitherto been located on the work table. A stop constructed separately and to be separately attached is provided for each of the three aforesaid machine tools. For each of the machine tools, the special stop thus has to be mounted and the other respective stops demounted. In order to substantially simplify and facilitate a simple change-over of the joinery machine with regard to the stop used in each case, it is proposed that the stops be formed by the two longitudinal sides of a box-like hollow body which is common to the circular saw, the machine plane and the mortiser and which extends essentially over the length of the work table, is mounted in a transversely displaceable manner and is set up in such a way that it can be fixed at least at one front end.

Patent DE-3224320-A1 (DE)
Title: Method and device for determining or suppressing a harmonic oscillation, contained in a measurement value, in the correct phase and with the correct amplitude, particularly in a direct AC converter for feeding an unbalanced load
Inventor: NEUPAUER HELMUT DR TECHN
IPC: B21B37/38
Filed: 1982-06-29
Abstract: In an actuator for a system of three measurement values, for which a reference variable (U*) with predetermined nominal frequency is predetermined, an actual-value vector (i) describing the measuring values (i1, i2, 13) is transformed by means of a first vector rotator (32') into a positive-sequence system circulating with the predetermined nominal frequency. The mean time values of the components of the transformed vector, formed by a filter (33') are transformed back into the space-fixed reference system by means of a second vector rotator (34'). This forms a quantity (i') containing the positive-sequence system fundamental contained in the measurement values in the correct phase and with the correct amplitude. In addition, the actual-value vector can also be transformed into the negative-sequence system, averaged and transformed back in order to determine the negative-sequence system fundamental (i''). When applied to the currents of a three-phase/three-phase direct AC converter, the addition of the two fundamentals supplies the fundamental current oscillation contained in each phase current with the zero crossings of which the anti-parallel rectifier bridges of the converter can be switched over. Including the negative-sequence system fundamental makes it possible additionally to obtain a correction variable which suppresses an unwanted negative-sequence system by being impressed on the reference variables. During the transformation of the actual-value vector into a positive-sequence system and negative-sequence system, rotating at triple frequency, the third harmonic can also be determined in order to obtain a correction variable for suppressing this harmonic. This makes it possible, in particular, to feed a high power from a three-phase system via a direct AC converter with connected balancing device into an alternating-current system without interfering system reactions, and the direct AC converter need only be dimensioned for a balanced active load. <IMAGE>

Title: System for storage of materials, preferably elongated materials
Inventor: SCHWARZ OSKAR DIPL ING
IPC: B65G1/04
Filed: 1983-04-30
Abstract: The system has adjacently disposed rows of receptacles for materials to be stored, which are seated on one another. They can be raised and lowered using a hoisting device. A lifting device is provided for loading and unloading the receptacle for materials to be stored. Between the rows there are empty spaces into which the receptacles of the respectively adjacent row can be laterally shifted with the hoisting device for loading and unloading of the respectively lower receptacle for materials to be stored. Because of the empty spaces, the receptacles for materials to be stored do not need to be shifted over the entire width of the respectively lower receptacle for materials to be stored. The hoisting device consequently covers only short paths.
