Patent DE-3346813-A1 (DE)
Title: Reinforced hemstitch formed by a sewing machine
Inventor: HANYU SUSUMU
IPC: D05B1/22
Filed: 1983-12-23
Abstract: A single-thread chainstitch and a two-thread hemstitch which is made by a single needle are formed simultaneously, a part of the thread (T2) which forms the hemstitch being guided through a loop (1) to form the chainstitch, in order thereby to produce reinforced sewing stitches which come loose only with difficulty even when the thread (T1) of the chainstitch tears. The sewing stitch thereby acquires sufficient strength and stability and is suitable as a sewing stitch with a smaller number of sewing threads. <IMAGE>

Patent DE-3424345-A1 (DE)
Title: Combustion chamber
Inventor: MACLIN HARVEY MICHAEL
IPC: F23R3/00
Filed: 1984-07-03
Abstract: A combustion chamber for gas-turbine power plants with a lining is indicated, which is formed from a high-temperature material. The lining has a number of parts or panels which are fastened to the bearing frame, which has great strength, by a fastening arrangement which is frictionally displaceable. As a result of this fastening arrangement, the lining is essentially separated from the forces which arise in the combustion chamber, while the frame is essentially isolated from thermal stresses which arise in the lining. Means are provided, in order to arrange and to fasten individual panels axially relatively to the frame. The panels can be continuous annular bodies or divided or segmented in the circumferential direction. In the last case, means are provided in order to hold individual panels in a displaceable frictional engagement with laterally adjacent panels and also to seal the butt joints. The individual panels can be removed easily for repair or exchange without the frame and the associated components having to be demounted.

Title: Heat-insulated composite profile
Inventor: ROEDL HEINZ
IPC: E06B3/263
Filed: 1984-07-07
Abstract: The invention relates to a heat-insulated composite profile (1) made of light metal for window frames or the like, which consists of two light-metal shells (2, 3) connected by an insulating core (4). To reduce the bimetallic effect which arises as a result of the different thermal expansion of the outer shell (2) and of the inner shell (3), the invention envisages that the outer shell has, for positive connection to the insulating core (4), a number of smooth longitudinal webs (5) which in the longitudinal direction of the web offer only a frictional connection which reduces tension peaks. The outer shell (3) is on the other hand connected to the insulating core (4) via longitudinal webs (6) which, by means of recesses or the like, provide a positive connection in the longitudinal direction of the profile as well. The differently shaped longitudinal webs are produced on the half-finished hollow-chamber profile by a knurling tool acting on one side. <IMAGE>

Patent DE-3435027-A1 (DE)
Title: Rodless cylinder
Inventor: RUCHSER ERICH
IPC: F15B15/14
Filed: 1984-09-24
Abstract: The invention relates to a rodless cylinder with an axially displaceable piston which carries a power-transmission element which projects to the outside through a longitudinal slot in the cylinder wall and to which a device to be actuated by the cylinder can be fastened. The power-transmission element is guided on the cylinder by means of guide grooves and self-adjusting guide strips. The guide grooves and guide strips have interacting conical surfaces which are constantly held in contact with one another by means of springs, as a result of which wear is compensated for and the power-transmission element is guided free of play on the cylinder. The forces occurring in the cylinder as a result of the operating pressure are absorbed, at least partly, by the force-transmission element, and widening of the cylinder is at least essentially avoided as a result of the guidance free of play.

Title: Laundry mangle
Inventor: ZEGGERT WERNER DIPL ING
IPC: D06F67/00
Filed: 1984-10-05
Abstract: In a laundry mangle for the smoothing of moist laundry articles and having a plurality of mangle rollers, the moisture is measured in the region of the last mangle roller, as seen in the direction of run of the laundry. As a function of the moisture measured directly on the laundry article, the control successively throttles the quantity of air sucked off from the last mangle roller and thereafter from the respectively preceding mangle roller down to a minimum value when a sufficient degree of drying is measured. When an insufficient degree of drying is measured, the air is successively increased up to a predetermined maximum value in reverse order in the various mangle rollers.

Title: Device for diagnosing a machine with continuous-path control
Inventor: HULSCH AXEL
IPC: G05B19/4063
Filed: 1984-10-17
Abstract: In order to diagnose the dynamic and static path accuracy of numerically controlled machines, the desired and actual value path curves of two selected axes can be represented on the monitor of the control. The desired and actual values are specifically stored for this purpose and represented true-to-scale superimposed on one another in a coordinate system using the method of axes. It is possible for the individual data to be followed, selected and represented as individual quantities by marking individual desired values with the associated actual values. Selected path segments can be represented enlarged, so that even the smallest deviations can be effectively detected.

Patent DE-3443712-A1 (DE)
Title: Steering-column lock and ignition lock for motor vehicles
Inventor: WITTWER REINHARD
IPC: B60R25/021
Filed: 1984-11-30
Abstract: The invention relates to a steering-column lock and ignition lock for motor vehicles, in which the lock cylinder is arranged at a distance from the steering column. A blocking pin serves for blocking the steering column and can be returned from a blocking position into a release position counter to the force of a push-out spring by key actuation. Provided furthermore is a key-withdrawal safeguard which senses whether the key is still inserted in the cylinder core. In this case, the blocking pin is retained in a stop readiness position by the linkage member of the withdrawal safeguard, until the key is removed virtually completely from the cylinder core. For a freely moving arrangement of the lock cylinder relative to the steering column, it is proposed to use two shafts, arranged coaxially relative to one another, between the lock cylinder and remaining lock parts, the said shafts starting from the cylinder core at the outer end, but at the inner end being connected on the one hand to the electrical switch and on the other hand to the eccentric. One of the two shafts is coupled to the cylinder core via a free passage for rotation and serves at the same time as a linkage of the key-withdrawal safeguard, which, after the withdrawal of the key, is moved back into the initial position again by the push-out spring of the blocking pin.
