Abstract: Hollow, spherical bodies of solidified alkali metal silicates having the general formula M2O:x.SiO2 where M is an alkali metal and x has a value greater than 3.6 and less than 12, said hollow bodies having an external diameter of from 1 to 5 mm, shell thickness of from 0.2 to 0.6 mm, a water content of from 10% to 30% by weight and a solids content of at least 70% by weight, the M2O content of the shell of said hollow bodies being greater internally and less toward the exterior surface, as well as the process of producing said hollow, spherical bodies of solidified alkali metal silicate. The hollow spheres are expandable resulting in the formation of foam spheres having a loose surface. The hollow spheres are useful to give a uniform filling of narrow cavities and in the covering of liquids by floatable, optionally surface-active silicate-containing materials.

Abstract: An article is provided comprising a plurality of straight spaced parallel extruded elements separated by a regularly undulated extruded element having an aspect ratio of at least about two, with undulations having opposed apexes on either side thereof, with apexes on one side of the undulated element being bonded to one of the parallel extruded elements and the apexes on the other side of the undulated element being bonded to the other of said parallel extruded elements. The article is formed by extruding a first filament-forming extrudable plastic mass to form a plurality of straight spaced continuous parallel elements, extruding (at a faster extrusion rate and between adjacent parallel elements) a second filament-forming extrudable plastic mass to form an undulatable element which is thinner than it is wide to provide a cross-section with an aspect ratio of at least about two, causing the undulatable element to undulate in its thin dimension and to bond to the straight spaced continuous parallel elements, and changing or permitting the change of the formed, extruded plastic mass so that subsequent bonding will no longer occur and so that the elements have sufficient structural integrity to maintain their extruded bonded shape.

Abstract: In a magnetic-tape-cassette apparatus comprising a servo device (39<sub>1</sub> for actuating at least one apparatus part (6). the servo device comprises a servo wheel (40). a relay-armature member (42), and an impulse relay (44) The servo wheel has circumferential teeth and at least one non-toothed circumferential portion (49), which in the rest position of the servo wheel faces a gear wheel 145) which is driven by a motor (16). Further, the servo wheel (40) carries an eccentric cam (46) and at least one latching projection (47), a servo torque being exerted on the eccentric cam (46) in the rest position. The relay-armature member (42) is pivotable between a latching position and an inoperative position. After a brief electrical energization of the impulse relay (44) the relay-armature member (42) is pivoted to the inoperative position under spring force, in which position the stop projection (54a) is clear of the latching projection (47) and, under the influence of the starting torque exerted on the eccentric cam (46), the servo wheel (40) is rotated, the circumferential teeth mesh with the gear wheel (45), the servo wheel is driven, and the apparatus part (6, 10, 12) is positioned, after which a reset projection (55a) on the relay-armature member (42) is actuated by the latching projection (47), causing the relay-armature member to pivot back to the latching position, subsequently the latching projection (47) abuts against the stop projection (54a), and the servo wheel (40) resumes the rest position. In order to ensure that, if the apparatus is in e.g. the "play" mode and the power supply fails, the apparatus part (6) is returned to its first or rest position, so that for example the pressure roller (12i is disengaged from the capstan (13). the servo device (39) comprises first means (71) for detecting the position of the apparatus part (6) and second means (72) having an input (73) coupled to an output (74) of the first means (71) and having an output (75) coupled to the impulse relay (44, 61) to supply a brief electric energizing signal to the impulse relay (44 611 at the instant at which the power supply (V,, V<sub>4</sub>) to the servo device is cut off if the apparatus part (6) is in its operating position and to ensure that no energizing signal is supplied at the instant at which the power supply (V<sub>1</sub>, V<sub>4</sub>) is cut off if the apparatus part (6) is in the rest position. Specific embodiments of the second means (27, 27') are disclosed that can well be integrated (Figure 7, 8).

Abstract: A face mask (10) formed from a single porous sheet made of a plurality of fibers into a generally cup shape shell that fits over the mouth and nose of the wearer and is held thereto by elastic straps (15). The mask filters breathed air passing there through. The border (13) of the mask is more tightly compacted during forming. The mask features rearwardly extending projections (16), preferably an arctuate ridge, on either side of the nose bridge area parallel to and close to the border of the mask. The peaks of the rearwardly extending projections (16) extend from the face mask in the direction of the face of the wearer to conform the portion of the mask close to its border to the contours of the face between the bridge of the nose and the upper areas of their cheekbones. The more tightly compacted rearwardly extending projections (16), rib elements (12) and the border (13) cooperate to provide shape retention and a spring action that holds the mask firmly but comfortably to the face of the wearer even when they talk or change facial expression to prevent the passage of air between the mask and the face.

Abstract: On the transmitter side, the audio signal is represented by numerous, spectral partial band signals, with quantised sampling values for each partial band signal. The quantasing of the sampling values in the individual partial bands is coded according to the listening thresholds of the human ear for the information signal reduction. The total signal flow over all partial bands remains constant. On the receiver side, the coded signals are decoded and combined into a wide band, digital audio signal. The quantising of the sample values in the partial bands is controlled according to the level value of each partial band signal, or according to level information derived from such signal.
