Title: Testing physical and/or chemical qualities of objects - using nuclear magnetic resonance spectroscopy and resonance recording for prepared section
Inventor: TANTTU JUKKA
IPC: G01R33/48
Filed: 1991-02-06
Abstract: A signal recording section is used as well as a prepared section. Measures are taken in the latter for reversal of nuclear spin and radiation outside the resonance region, i.e. off-resonance irradiation. The necessary current is supplied from a gradient current source (GC) controlled by a spectrometer. A reversal pulse rotates the magnetisation by about 180 deg.. An excitation pulse rotates the partial return magnetisation in a desired angle. A spin echo signal is generated by a so-called gardient conversion. The duration, amplitude and frequency of the irradiation outside the resonance region is selected such that the intensity of a certain material, e.g. blood vessel, is maximised in relation to other material, e.g.  biological tissue, contained in the object. USE/ADVANTAGE - Human or animal bodies, tree trunks, food and industrial products. Max. contrast.

Title: Hydraulic stabilising jack for mobile jib crane - has supporting foot connected to ram by cam controlled four bar chain linkage
Inventor: MAETZE MATTHIAS
IPC: B66C23/80
Filed: 1991-02-14
Abstract: The foot (11) of the jack is connected to the ram of the hydraulic cylinder (2) by a four bar chain linkage (5, 6). An extension of one link (5) is guided along the profile of a cam plate (3) fixed to the cylinder. When the ram is extended to the supporting position, movement of the link along the cam profile causes the foot to rotate into the level position as it is also moved directly under the ram. The hemispherical end of the ram sits in the cup at the top of the foot, providing a direct path for the supporting force, Self-alignment of the foot on the ground is able to take place. USE/ADVANTAGE - Supporting foot of jack is stowed with adequate ground clearance. Set-up time and manual effort are minimised.

Title: Injection-moulded plastic bucket
Inventor: KEMMERICH HERBERT
IPC: B29C45/00
Filed: 1993-03-05
Abstract: The invention relates to an injection-moulded plastic bucket according to Patent Application P 4230788.0, in particular an injection-moulded, inward-edge plastic bucket, having a bottom, a wall which widens from said bottom towards the upper edge, and a carrying handle, receiving elements for a carrying handle being provided in the region of the upper edge of the wall at diametrically opposed points, and the upper edge of the wall serving at the same time to receive a lid in an engaging and sealing manner. By means of the invention, an injection-moulded, integral, inward-edge plastic bucket with an integrally cast-on carrying handle is to be provided, which allows secure and sealed attachment of a lid, and in which the lid can be removed only after removal of the tamper-indicating closure. The object on which the invention is based is achieved in that a circumferential edge (9) directed vertically downwards is moulded onto a web (8) with slight spacing below the upper edge (3) of the wall (2) and with spacing from the wall (2), in that the circumferential edge (9) is provided with a circumferential depression (11) to receive the edge (6) of the lid, and in that the web (8) of the circumferential edge (9) is recessed at least at one point on the circumference of the bucket, forming a gripping depression (11) which is covered by a flap (12) attached to the circumferential edge (9) when the lid (4) is fitted on. <IMAGE>
Patent DE-4313877-A1 (DE)
Title: Ball differential
Inventor: RIEMANN STEPHAN
IPC: B60K17/16
Filed: 1993-04-28
Abstract: The invention relates to differentials which are driven and create a speed adjustment between the two ends of a driven shaft. Currently available differentials function by positive interlocking and are large and expensive by virtue of the toothed components. Destruction of the power-transmitting components results in failure of the differential. The ball differential is based on the principle that balls as drive and adjustment transmitter transmit the force introduced non-positively to the two axles and permit a speed adjustment between the two axles. The pressure for the frictional connection to the balls is built up by springs and is regulatable or adjustable from outside, which permits variations from slip to locking. The use of simple, standardised parts means that the ball differential can be compact and inexpensive to manufacture. With little clearance between differential case and plates, in the event of a ball fracturing the springs press the plates and differential case together, forming a frictional connection as "emergency running characteristic". <IMAGE>

Filed: 1993-06-01
Abstract: The mould for continuous casting of metal, in particular, steel in ingot form has an open-ended mould space (4) formed by a pipe (3) made of a material with good thermal condcutivity. At the entry side, the cross section of the mould space is provided with regularly distributed enlargements in the form of bulges (6) which while diminshing in size in the direction of casting motion - extend at least over a length (10) of the mould space (4). These bulges help to shape the cross section of the casting during its passage over the length (10). The opposite outer walls of the pipe (3) are parallel to one another, or their generatrix lines are parallel to the direction of casting motion. The bulges (6) are produced by means of an appropriately shaped mandrel in a continuously cast copper pipe blank which is subjected to further forming operations. The mould space (4) has a rectangular cross section, with the bulges (6) in all sides having approximately the same depth-to-width ratio. Pref., in the case of a square cross section, this ratio is strictly the same for all sides. An explosive forming process is used to produce the mould (3). In operation the mould is surrounded with a tubular jacket (18) for water cooling. USE/ADVANTAGE - In the metallurgical industry. In comparison with known alternatives, it is simpler and cheaper to mfr.. It also ensures greater uniformity in the mould temp. distribution.
