Title: Large scale radar ground search method - using variable, distance-dependent radar operation and two=stage selection of road traffic
Inventor: BRUSCH JOSEF
IPC: G01S13/524
Filed: 1991-06-26
Abstract: The method involves receiving data from radar appts. located on high flying platforms at a safety distance of about 30 km from the front edge of defence. The data are transmitted to ground stations and evaluated. The radar appts. is operated in dependence on distance such that areas of terrain up to 30 km from the front edge of defence can be completely registered in Moving Target Indication operation. A two-stage selection of road vehicle traffic is carried out to avoid irrelevant data, and vehicle groupings are determined. In the region between 30 and 150 km from the front edge of defence, vehicle convoys are synthesised on the basis of stored road routes. ADVANTAGE - Improved reconnaissance.
Patent DE-4121489-A1 (DE)
IPC: C21D9/68
Filed: 1991-06-26
Abstract: The invention relates to an oven used as intermediate storage between the spindle-less coiling device (23) for the cast strip (4), located downstream of a thin slab casting plant, and to the associated device (14) used for uncoiling prior to the rolling mill (15). In order to provide an oven between the cast strip coiling and uncoiling devices which facilitates both a good heat supply for the cast material and possibly subsequent heating for the coils (6), and which provides considerable storage capacity prior to the rolling mill, it is proposed that a pallet circulation system is used consisting of pallet trucks (9) which can follow a transit cycle through the oven (11) and can move transversely at the entrance to and exit from the furnance (8, 13) and return (17) alongside the oven. The immediately adjacent platforms of the pallet trucks (9) are made of fireproof material and form the hearth of the oven (11). They are provided with saddle elements, made from material having low thermal conductivity, to receive the strip coils (6).

Title: Sewing machine - has gripper and spool thread brought from external reel through hollow drive-shaft
Inventor: EICHHORN RUDOLF
IPC: D05B57/22
Filed: 1992-01-29
Abstract: The shuttle mechanism on sewing machine has driveshaft to revolve the gripper, with thread fed continuously from spool. The driveshaft is arranged to have central bore, so that the thread may be fed through from an external reel, without accumulation on an encapsulated spool. Pref. the shuttle unit beneath the needle plate, has hollow passage along the interior of the drive gear and to the fixed spool case, running with projection from the case in a groove. The spool case contains an open end spool held by a plate and screw. The case is prevented from rotation by the finger fixed to the machine base. The thread from the interior is guided and tensioned from the spool in the usual manner. There is also tension for the thread as it is drawn from the external reel. The thread passes along the bore and into the spool case through passage in the central shaft of the case, and is unhindered by the spool at the exit. The needle brings down the top thread which is trapped by the gripper as it revolves, forming loop which passes across the face of the spool and enclosing the thread. The loop is taken back by the take-up lever, forming a stitch which locks the two threads. ADVANTAGE - The repetitive process of winding spool and fixing it into the shuttle encapsulation is eliminated. The top thread reel may be the same size as the bottom thread reel, and sewing may continue uninterrupted for this period.
