Abstract: A rotation control circuit for a Hall motor of reduced-size and suppressed irregular rotation and having a controller (34) that sto­res in a memory circuit (34A) data indicative of an irregular magne­tization of a rotor magnet (20A) derived from a change of the magnetic field of the rotor magnet (20A) detected by a Hall element (H₁,H₂,H₃) as an irregular rotation information signal, in which the irregular rotation information signal is input to a speed servo loop of the Hall motor, whereby the change of magnetic field of the rotor magnet (20A) is used as an FG signal to form a speed servo circuit.

Abstract: In a cooling system including a refrigerant compressor (40) for use in a vehicle for refrigerating a refrigerator compartment, the refrigerant compressor is a hermetic type compressor containing a DC electric motor as a compressor driver. An electric generator (42) is actuated by an engine (26) of the vehicle to generate an AC voltage which is, in turn, rectified by a rectifier (47) to produce a DC power for driving the DC electric motor. A switch is provided to switch over from the electric generator to a commercial AC power source so that the commercial AC power is rectified by the rectifier to supply the DC power to thereby enable to drive the compressor by use of the commercial AC power source during a time period when the engine is stopped. In order to cool a passenger compartment of the vehicle, another compressor (14) is provided to be driven by the engine. The other compressor can be temporally used for compressing refrigerant for refrigerating the refrigerator compartment together with the refrigerant compressor by valve control.

Abstract: A technique for the masking of quantizing noise in the coding of audio signals is adapted to include geometric interpolation between the thresholds for a tone masking noise and for noise masking a tone, in order to reduce use of bit-rate capability where it is not necessary for transparent or high quality. The technique is usable with the types of channel coding known as "noiseless" or Huffman coding and with variable radix packing. The stereophonic embodiment eliminates redundancies in the sum and difference signals, so that the stereo coding uses significantly less than twice the bit rate of the comparable monaural signal. The technique can be used both in transmission of signals and in recording for reproduction, particularly recording and reproduction of music. Compatibility with the ISDN transmission rates known as 1B, 2B and 3B rates has been achieved.

Abstract: A method and device for the continuous production of moulded elements from inorganically bonded materials is presented. This involves compressing a strand of material in a high-pressure compressing unit in such a way that its thickness is less than the set thickness of the finished strand of material and its density is greater than its set density. In the following calibrating device, no active pressure application takes place. It is essential here that, after leaving the high-pressure compressing unit (2), the strand of material runs through a pressureless zone (5) and, following that and immediately before entering the calibrating device (4), is compressed to such an extent that the recovery occurring during running through the pressureless zone (5) is either completely eliminated and the density of the strand of material is greater than the set density of the finished strand of material and the thickness is less than the set thickness of the same when entering the calibrating device (4) or the recovery is eliminated only to such an extent that the thickness of the strand of material corresponds to the set thickness and the density of the strand of material corresponds to the set density of the finished strand of material.

Abstract: 2.1 The recycling of refrigerators having insulations of polyurethane foam is a pressing issue on account of the high content of foaming agents in the form of chlorofluorocarbons. Until now, after removing the refrigerating units, such refrigerators have been dumped without any further measures on open household refuse tips. 2.2 For environmentally conscious and safe disposal with a virtually assured possibility of reclaiming the component parts of the refrigerators 15, they are crushed in a closed working space 1 by means of a crushing means 4 into fist-sized fragments 19, which are blasted with granular blasting medium 26, disintegrating the cells of the polyurethane foam. The chlorofluorocarbons thereby liberated are extracted by suction and precipitated, the blasted fragments 19 are sorted and the polyurethane foam remains are compressed by a ram press 10 to form briquettes 46. 2.3 The method serves for complete recycling, in particular of domestic refrigerators, freezer chests and refrigerated counters. 3.

Abstract: A flexible drive coupling for transmitting rotational forces between respective flanges (14,16) of a driving shaft and a driven shaft (18,20). The flexible drive coupling has, in a substantially planar circular configuration, a number of wedges (12). The wedges (12) have respective end faces facing the adjacent wedges and connected thereto by flexible elements (26). Alternate wedges (12) attach respectively to the flanges (14,16) of the driving and driven shafts (18,20). The flexible elements (12) consist of a link (28) between two end plates (30). The mating faces of the link (28) and the end plates (30) are curved so that they co-operate one with the other. An elastomeric filler (38) occupies the space between the curved surfaces of the end plates (30) and the links (28) permitting each end plate (30) to pivot with respect to the link (28) by deforming the elastomeric filler (38). The end faces of the wedges (12) and, the corresponding faces of the end plates (30) of the flexible elements which face them, have co-operating tabs (40) and recesses (42) to prevent relative radial and axial movement. On attaching the flexible drive coupling to the driving and driven shafts (18,20), the wedges (12) can be forced radially inward and so secured that the flexible elements (26) are pre-loaded in radial compression.
