Inventor: MUELLER FRIEDRICH DIPL-ING
IPC: C03B5/185
Filed: 1990-07-22
Abstract: A melting vessel for the preparation of glass has heating means in the upper furnace and vertical heating electrodes in rows parallel to a transversely directed bottom wall in the melting basin. To establish a stable position of the batch blanket on the melting bath and a stable convection roll and to prevent parts of the batch penetrating into the refining area at a high specific melting rate, the bottom wall is given an immersion height of 75 to 90% of the melting bath depth and a distance from the front basin end wall of 75 to 90% of the basin length. The electrodes are arranged in front of the bottom wall in two rows, of which the front row is at a distance from the end wall which is at least half the basin length. Respectively neighbouring electrodes of both rows form a rectangle, preferably a square. The immersion height of the electrodes into the melting bath is 40 to 100% of the height of the bottom wall. <IMAGE>

Abstract: A digital transmission system comprising a transmitter (3, 5, 7, 8) and a receiver (14, 15, 16, 18). The medium (6) comprises an information channel (T₁, T₂, ..., T n ) and an auxiliary channel (T n+1 ). Through the information channel information is transmitted, for example a digital audio signal. Through the auxiliary channel an auxiliary signal is transmitted. This auxiliary signal comprises sync information (100, 101, 102, 103, 104, 105) and additional information (106). 
     The auxiliary signal is composed of successive blocks (..., B n-1 , B n , B n+1 , ...). A first block (B n ) comprises a first block section (header) and a second block section (body). The first block section of the block (B n ) contains a sync word (101) and a first codeword (102), in this order. The first block section of the second directly successive block (B n+1 ) contains a sync word (104) and a second codeword (105), in this order. The first codeword (102) expresses that the second block section (106) of the first block (B n ) contains additional information. If there is also additional information in the second block section (107) of the second block, the two codewords are equal. If the block section (107) does not contain additional information, the two codewords are unequal. The first block section of the first block (B n ) further contains a third codeword (100), the sync word (101) and the first codeword (102), in this order. 
     The first block section of the second block (B n+1 ) further contains a fourth codeword (103), a sync word (104) and a second codeword (105), in this order. 
     The fourth codeword also expresses that additional information is contained in the second block section (106) of the first block (B n ). 
     The third codeword is now equal to the fourth codeword if the second block section of the block (B n-1 ) directly preceding the first block (B n ) also contains additional information. The two codewords are unequal if the second block section of this block (B n-1 ) does not contain additional information.

The apparatus (1) has a set of pleating rollers (7), each with a series of teeth (9) spaced apart about the periphery (8). The pleating rollers (7) are mounted for rotation so that the teeth (9) intermesh in a mesh zone (10), sheet material (M) feeding through the mesh zone (10) during apparatus use being caused to fold by the teeth (9) into successive pleats (P). A lacing needle (20) projects toward the pleating rollers (7) and has a leading end (21) positioned in the mesh zone (10). Sheet material pleats (P) successively formed in the mesh zone (10) are pierced by the leading end (21) and received onto the lacing needle (20). The lacing needle (20) is connectable to a flexible line (L) for lacing through the material (M). A set of feed rollers (25) are positioned downstream of the pleating rollers (7), each with a circumferential groove (30) and being mounted for rotation so that the circumferential grooves (30) are in register one with another. The lacing needle (20) is positioned in the circumferential grooves (30) and supported by the feed rollers (25). Rotation of the feed rollers (25) strips the sheet material (M) from the lacing needle (20) and onto the flexible line (L) so that the line (L) is laced through the sheet material (M).

Title: Servo tracking for helical scan recorder.
Inventor: HUGHES TIMOTHY C
IPC: G11B15/467
Filed: 1990-11-06
Abstract: In a servo tracking method and apparatus, a servo head (S) of a helical scan recorder (30) endeavors to travel equidistant between two servo signal-bearing stripes recorded on the tape (32). The recorder (30) determines a reference-crossing time at which the servo head (S) begins to cross a horizontal reference line (606) drawn with respect to the beginning of a stripe on the tape (32). The servo head (S) samples the amplitude of a servo signal provided on the tape (32) at a plurality of predetermined times after the reference-crossing time. A servo tracking circuit (175) uses the amplitude of the servo signal at the predetermined sampling times to determine how to adjust the position of said head (S) relative to the pitch of said stripe.

Abstract: Machine-setting values with similar functions are combined as a group in a setting-value table and as many tables as there are groups are assigned to service units of this machine, there being obtained from each table parameter vectors which bring about a specific machine setting, and the parameter vectors as a whole representing (for example, on a graph axis) settings for the associated service unit. The group formation of setting values with regard to a fine-cleaning machine comprises, for example, setting values (d) of the distance of the knife or carding element from the beating circle, the peak density (Z) of the carding element, the clamping distance (P4) from the feed funnel to the clothing of the opening roller, and the rotational speed (n) of the opening roller, which are combined in a first group and which are incorporated in a first table for forming parameter vectors for the cleaning intensity (P71), and the distance of the offset (S) between the guideplate and knife (P31) and the length (L) of the separation gap (P32) between the knife and guideplate are combined in a second group and incorporated in a second table (Figure 3) for forming parameter vectors for the wastage, so that the setting elements of the fine-cleaning machine are interlinked via these parameter vectors and the characteristic numbers of the parameter vectors are each assigned to a service unit, these service units jointly defining in each setting a working point of the fine-cleaning machine as a result of the interlinking of the setting elements by means of the table combination.

Abstract: A fuel injection type internal combustion engine comprising a cylinder head which is provided with a pair of intake valve bores (6₁,6₂) facing a combustion chamber, a single intake passage (8), and a pair of intake ports (9₁,9₂) between which a partition wall (2a) is interposed and which connect the intake passage (8) and the intake valve bores (6₁,6₂) to each other, and a fuel injection valve (65) disposed to extend in a direction from the single intake passage (8) toward the intake valve bores (6₁,6₂) and having a fuel ejection port (77), in the vicinity of which air assist ejection ports (86) are disposed for finely dividing the fuel. The air assist ejection ports (86) are disposed at opposite sides of the fuel ejection port (77) on a plane (L) substantially including the fuel ejection port (77) and that end edge of the partition wall (2a) which is closer to the intake passage (8), so that the air assist injection directions intersect each other and the fuel jet. This ensures that the fuel jet is narrowed in width at a portion corresponding to the partition wall (2a) by air flows from opposite sides, so that the entire fuel jet is flattened. Therefore, the narrowing of the width of the fuel jet at the portion corresponding to the partition wall (2a) makes it possible to suppress the deposition of the fuel on the partition wall (2a) and to suppress the deposition of the fuel on inner surfaces of the intake ports (9₁,9₂) in the vicinity of their connections with the partition wall.
