Patent DE-3268092-D1 (DE)
Title: Article suitable for wiping hard surfaces
Inventor: BARBY DONALD
IPC: C11D17/04
Filed: 1982-05-27
Granted: 1986-02-06
Abstract: An article is disclosed which is suitable for wiping hard surfaces such as glass to give a streak-free finish. The article comprises a substrate (preferably paper or non-woven fabric) carrying a homogeneous aqueous composition having a surface tension below 45 mNm-1 and which on drying does not form discrete droplets or particles larger than 0.25  mu m. The liquid composition advantageously includes a (preferably nonionic) surface-active agent and a partially esterified resin such as a partially esterified styrene/maleic anhydride copolymer. The article may be wet (for example, coated or impregnated with the liquid composition) or dry up to the point of use (for example, the liquid may be within pressure-rupturable microcapsules). Preferably the article is produced by a process which includes prewashing the substrate to remove any potentially streak-forming impurities.

Patent DE-3280460-D1 (DE)
Inventor: GIDDINGS GARY MICHAEL
IPC: G11B7/09
Filed: 1982-10-27
Granted: 1995-01-05
Abstract: A method and apparatus for rapidly moving a reading beam of light radially relative to a rotating record disc, to impinge on a selected target track on the disc and recover information recorded on it. The apparatus first radially translates an optical system that directs the beam onto the disc at a relatively high speed until it is within a prescribed radial distance of the target track. Thereafter, an element of the optical system is controllably deflected such that the beam moves incrementally across a prescribed plurality of tracks during each disc revolution, until reaching the target track. The information recorded on each track includes a unique address signal, and movement of the beam relative to the disc is controlled according to the difference between the respective addresses of the track currently being scanned and the target track. If the apparatus fails to properly recover a track address signal, it estimates the address of the track currently being scanned, and updates its control of the beam's radial movement based on that estimate. <IMAGE>

Title: Method and circuit arrangement for transcoding code words
Inventor: VON SICHART FRITHJOF DR
IPC: G06F7/00
Filed: 1983-08-24
Granted: 1986-06-05
Abstract: For transliterating code words of a code having m-place code words into the corresponding code words of a different code likewise having m-place code words, individual bits of the code word to be translitereated are forwarded during serial input into a m-place shift register or during the serial output therefrom. These bits are forwarded non-negated or negated from register stage to register stage over a respective forwarding circuit depending upon the measure or criterion of coincidence or non-coincidence between the code word to be transliterated and the code words of the different code. This occurs in such manner that the traversing bits experience a respective negation in front of and after a register stage whose position within the shift register corresponds to the position of non-coinciding bits within the two code words.

Title: Method for controlling the welding process in the production of pipes with a longitudinal seam
Inventor: KOCH FRIEDRICH OTTO DIPL ING
IPC: B23K11/25
Filed: 1983-08-13
Granted: 1987-11-05
Abstract: It is necessary to determine the effects of welding pressure in order to control the high-frequency welding process in the manufacture of pipes with longitudinal seams. It has been discovered that measurements of the height of the welding bead provide an approximation that is satisfactory for determining the mass of the bead, which is proportional to welding pressure in known pipe geometry. The height of the bead is transmitted by an optical system to the diode matrix of a commercially available diode-matrix camera. The results are processed to control welding pressure.

Abstract: Miscorrection of triple errors is avoided in a memory system equipped with a single bit error detection and correction/double bit error detection code by providing a double bit error logging technique. The address of each fetched word is logged in which a double bit error is detected. The address of each fetched word in which a single bit error is detected is compared with all logged addresses. If a coincidence is found between the compared addresses, a triple bit error alerting signal is generated and error recovery procedures are initiated.

Abstract: An expansion dowel assembly is made up of an axially extending dowel body and an expansion member in contacting engagement with the dowel body. The expansion member extends in the axial direction of the dowel body and is formed by a main part and an extension part projecting axially from the main part in the insertion direction of the assembly into a borehole. The cross-sectional area of the extension part transverse to the axial direction is smaller than the adjacent corresponding cross-sectional area of the main part. The extension part is shaped relative to the main part to increase the contact area of the expansion member with the dowel body and to prevent the development of excessively high surface pressures at the front end of the expansion member.
