Patent DE-4131812-A1 (DE)
Inventor: JAKOB ANDREAS
IPC: F16B1/00
Filed: 1991-09-24
Abstract: Screwed connection for connecting two spaced-apart structural members (10,12), in particular metal sheets, having a screw, the head (16) of which bears on the outer side of one structural member (10), and having a first nut (48) which bears on the outer side of the second structural member (12). A spacer sleeve (30) exhibits an external thread and can be screwed into a second nut (44) which is attached on that side of the first structural member (10) which is opposite the screw head (16). The screw exhibits a front threaded portion, the major diameter of which is greater than the diameter of a threadless shank portion. The spacer sleeve (30) exhibits an internal threaded portion (34), the minor diameter of which is equal to or greater than the diameter of the threadless shank portion. Before the screwing-in procedure, the threaded portion of the spacer sleeve (30) engages in a frictionally locking manner with the threaded portion of the screw such that the spacer sleeve (30) can be screwed, with a sufficient moment, into the second nut (44). This engagement can be released by means of a higher torque. <IMAGE>

Title: Flow control device for gases through engine cylinder head - uses gas ducts in walls of manifold to reduce swirl effects and increase flow-rates
Inventor: ROTHENBERGER PETER
IPC: F02M26/20
Filed: 1992-03-25
Abstract: The cylinder has the inlet manifold (12) and the exhaust manifold (19) meeting in a gas transfer section (4) bounded by the inlet and outlet valves set at angles. Swirl effects at the manifold edges, generated by tight contours and by the valve guides, are reduced by gas compensation ducts (10, 13, 16, 17) linked to a variable gas control. Gas is either taken from the swirl areas, exhaust gases recycled, air pumped into the swirl areas or a combination of the options are applied to optimise the gas flow through the manifolds. The air pressure is generated by an air pump (35) and the suction by a venturi pump (41). Two multi-way control valves (31, 33) and a processor control (40) regulate the compensation. ADVANTAGE - Improved gas flow, improved exhaust emission control.
Patent DE-4211276-A1 (DE)
Inventor: LUCKHARDT WOLFGANG DIPL ING
IPC: B25B23/04
Filed: 1992-04-03
Abstract: The description relates to a holder for holding, guiding and automatically releasing fixing and auxiliary fixing means, e.g. nuts, bolts and rivets, in a device for pressing or securing the means to a metal sheet, which is explained here with reference to nuts. The holding device keeps the nuts in a defined, stable position during their transport from an initial position to the operative position. It consists of two holding claws (82) pivoted on the block (20) so that they can be moved from a closed position in which they hold the nuts (60) on the block (20) and an open position in which they release the nuts (60). A positive guide (90) for the holding claws (82) ensures that they remain in their closed position when the block (20) is pushed outwards and are released into the open position only when the block (20) has reached the operative position.
Patent DE-4217149-A1 (DE)
Inventor: HAUCK ALBERT
IPC: B21B45/02
Filed: 1992-05-23
Abstract: The invention relates to a rolling mill for bar or wire rod with a continuous rolling train for small sections or wire, comprising a single- or multi-strand roughing train with a pilot stand, at least one single-strand intermediate train arranged on the delivery side of the roughing train and having a cooling section with an adjoining compensating section and an intermediate stand group, and a finishing train arranged on the delivery side of the said intermediate train and having a single-strand finishing stand group. To overcome nonuniform temperature distributions over the length of the rod and the cross-section of the rod and to compensate for changing final speeds due to differences in cross-section caused by unavoidable stretching between the stands of the roughing train, it is proposed to arrange between the pilot stand (2) and the intermediate stand group (3), a first compensating section (10) with a 180 DEG  loop (25) of the rolled stock through a horizontal looper (20) and to arrange between the intermediate stand group (3) and the finishing stand group (4) a second compensating section (11) with a 180 DEG loop (26) of the rolled stock through a second horizontal looper (21).

Title: Compsn. for ex vivo propagation of haematopoietic precursor cells - contains interleukin(s) 1,3 and 6, erythropoietin and stem-cell growth factor, generating cells of high clonogenic potential
IPC: A61K35/12
Filed: 1992-12-03
Abstract: Combination of haematopoietic growth factors contains interleukin(IL)-1,3- and -6. erythropoietin (EPO) and stem-cell growth factor (SCF). Also new are solns. contg. this combination. Pref. the soln. contains 10-100 (pref. 50-150) ng/ml IL-1; 1-1000 (pref. 50-150) U/ml IL-3, 10-1000 (pref. 50-150) U/ml IL-6; 0.1-10 (pref. 0.5-1) U/ml EPO and 10-1000 (pref. 50-150) ng/ml SCF. Opt. it also contains gamma interferon (INFG) at 1-1000 (pref. 50-150) U/ml. Peripheral blood precursor cells are isolated, pref. by immunoaffinity adsorption or fluorescence-activated cell sorting, to enrich CD34 positive cells. These are then cultured in presence of a soln. of the new combination, in autologous plasma or in nutrient medium, which may be serum free or contain animal serum. USE/ADVANTAGE - The compsn. is used for ex vivo propagation of haematopoietic precursor cells, specifically CD34 positive cells. The propagated cells are partic. used after high dose chemotherapy for rapid reconstitution of haematopoiesis. The compsn. generates precursor cells with high clonogenic potential and a high proportion of cells able to form multiline colonies (i.e. terminal differentiation is inhibited). Partic. omission of colony-stimulating factors (present in known compsns.) increases the no. of clonogenic cells, while addn. of IFNg further increases the no. of nucleated and colony-forming cells. Not only are myeloid precursors amplified but also early haematopoietic and erythrocyte precursors. Large no. of precursors can now be generated from a small amt. of blood, avoiding the need for multiple apheresis stages.

Title: Sewing machine - has a sewing head fitted to the arm in a release mounting to simplify thread changes
Inventor: HASHIRIDE TADAAKI
IPC: D05B69/30
Filed: 1993-03-30
Abstract: The sewing head of the sewing machine, contg. the needle holder moved up and down by the arm shaft, is fitted to the outer end of the arm in a release mounting. A converter, in a release fitting at the needle holder, turns the rotation of the arm shaft into a vertical reciprocating movement for the needle. A thread feed within the sewing head passes the thread to the needle at the lower end of the needle holder. The tread take-up at the arm, has a synchronised movement with the vertical movement of the needle holder to take up the loose thread loop and release the needle thread. The thread take-up has a lever with a guide groove for the thread, and a cover to open and close the groove. A thread tension control is at the sewing head, together with a thread guide system. A register acts with the sewing head and needle holder for exact positioning in a vertical setting to engage the needle holder with the movement drive direction converter, when the head is fitted to the arm. USE/ADVANTAGE - The mechanism simplifies a thread change at the sewing machine.
