Patent DE-3904421-A1 (DE)
Title: Active stabilisation of laser resonators
Inventor: LESSMUELLER ECKHARD
IPC: H01S3/139
Filed: 1989-02-14
Abstract: Even "stable" lasers pulsate (breathe), that is to say that their mode profile undergoes fluctuations with periods of from a few minutes up to hours. This is particularly true during the warm-up phase of the laser. Power measurement can scarcely detect these fluctuations, even though they are the source of many problems with power lasers, especially in the case of sensitive processes. The novel device continuously regulates laser resonators to optimum constant mode. The device consists of a motor-driven adjustment mechanism on at least one of the resonator mirrors, a simple measurement device for the mode profile, and a regulator unit, for example a program-controlled computer. The novel method consists in that the regulator unit continuously actively keeps the resonator optimally adjusted by means of small movements of the resonator mirror. In addition, "search runs" are executed at selectable time intervals, by means of which the mode is trimmed to the absolute maximum. <IMAGE>
Patent DE-3905754-A1 (DE)
Inventor: TEKATHEN JOHANN
IPC: B65G19/22
Filed: 1989-02-24
Abstract: PCT No. PCT/DE90/00053 Sec. 371 Date Jan. 31, 1991 Sec. 102(e) Date Jan. 31, 1991 PCT Filed Jan. 29, 1990 PCT Pub. No. WO90/09941 PCT Pub. Date Sep. 7, 1990.Chain webs for chain conveyors, which are primarily used in underground mining and in tunnel building for the transport of large quantities of materials, consist of mutually engaging horizontal and vertical chain links in which the horizontal links of the two adjacent chains are joined by a one or two-piece bracket running across their longitudinal direction, sufficiently raised above them and having a reversible tooth shape. This results in a kind of toothed chain providing the optimum power transmission from the chain wheel to the chain web, where both chains run exactly in the middle of the belt, as is usual in double-centered chain conveyors. The special shape of the reversible teeth makes it possible to use such a chain web on both sides and to move it forwards and backwards without any risk. Owing to the smooth and broad-based power transmission, the reversibility of such chain webs and the optimal conveying properties, times between breakdowns are substantially longer, which is of special importance in underground mining on account of the high rates of wear prevailing there. This is especially true of the two-part brackets connected by a heavy-duty spring sleeve.

Filed: 1989-04-14
Abstract: An electronic watch has an electronic circuit 12 to perform advanced features that is able to distinguish between a first case in which an access code for entry into a programming mode has been correctly entered and the programming operation has been correctly done, from a second case in which the access code has not been correctly entered and/or the programming has not been done correctly. Access to a programming mode of a perpetual calendar feature built into the watch is controlled by requiring at least one specific manipulation of a time-setting rod 10 to perform one function other than the functions of correction of the date and day, and to control the watch in the manner of an ordinary watch in the second case and to attribute, in this case to at least one manipulation of the rod, the functions of correction of date and day. The access code is achieved by a combination of axial and rotational actuations of the winding stem or time setting rod 10 to operate switches A, B, C & D in a pre-set sequence. <IMAGE>

Patent DE-3943072-A1 (DE)
Inventor: DRESSLER HANS-JOACHIM
IPC: H03H17/00
Filed: 1989-12-27
Abstract: The invention relates to an interpolative analog/digital converter for band-pass signals in which the amplitudes of the scanning values are quantized in 2 consecutive stages. The first stage contains the actual analog/digital interface and the second stage is purely digital. The amplitudes of the scanning values are not quantized, as in other processes, using finely quantizing elements at the analog/digital interface, but by overscanning, shaping of the quantization noise spectrum and digital interpolation. As a result, very coarsely resolving elements (with only 2 quantization stages in the extreme case) can be used at the actual analog/digital interface.

Patent DE-4035398-A1 (DE)
Inventor: BRAEGAS PETER DIPL ING
IPC: G01C21/20
Filed: 1990-11-07
Abstract: The proposal is for a process for the high-frequency data transmission of driving information from fixed beacon transmitters (2, 4) to vehicles (7, 8) in which there are at least two fixed beacons. To prevent the extinction of the wave field of the at least two beacons (2, 4) by standing waves it is proposed to modulate the high-frequency signal of the beacon transmitters with a spectrum similar in noise so that standing waves cannot form. In this way all vehicles passing the beacons can receive the information transmitted by them without the occurrence of interference by the extinction of wave fields.
Patent DE-4036141-A1 (DE)
Inventor: HALSTRICK KLAUS

Filed: 1990-11-13
Abstract: A novel bottle crate is described which has at the sides (3) self-supporting carrying handles (9) which are formed by the gripping openings (8) leading in each case at one end up to the top edge of the crate. Both the self-supporting carrying handles (9) and the adjoining wall parts (6) are expediently formed from hollow profiles. Further hollow profiles (6, 11) form end-side carrying handles (10) and lead to the crate bottom (1, 2) so that, in total, a combination of hollow profiles allows high rigidity and strength with low weight. The self-supporting carrying handles (9) result in very good carrying convenience. Additionally, a further inside carrying handle (13) may be provided which connects the free ends of the self-supporting carrying handles (9) to one another. As a result, the strength is further increased and the crate can be carried without great inclination and thus with good clearance above the ground. <IMAGE>
