Title: Yarn feed store drum - has air flow to carry and guide yarn round the drum
Inventor: GOEBBELS HEINZ-DIETER
IPC: B65H51/16
Filed: 1990-05-31
Abstract: The yarn store assembly, in a textile machine which produces or handles or works yarns, has a yarn guide (3) which surrounds the store drum (2) to give a ring-shaped gap (29) between them.  A gas stream, pref. of air, is generated (17) to flow through the gap (29) to carry and guide the yarn (4) wound round the store drum (2). Pref. the yarn guide (3) has a number of blowing jets (17) aligned at the storage drum (2) at a tangent, or with tangential direction components, distributed in a ring round the circumference.  The blowing jets (17) are fitted to a vessel or air feed channel (19) round the store drum (2). The yarn guide (3) is stationary, or virtually stationary, with a yarn laying slit aligned against the store drum (2). The guide (3) incorporates an air feed channel (19) in a ring round the drum (2) which is interrupted to give a clear passage from the laying slit in the guide (3) through to the drum (2). The drum (2) rotates on bearings (13,14) which, at the take-off side, are either within or outside the drum (2). The store drum (2) has a cylindrical or conical mantle surface (9), with a rounded or polished yarn guide beading (11) at the take-off end, where there is a yarn take-off guide (7). The drum (2) rotation is induced by the draw tension of the yarn (4) as it is taken off. ADVANTAGE - The assembly has a simple construction and operation, to hold a long length of yarn material in store and deliver it to the machine in a trouble-free action. The storage action also gives a simultaneous take-up and delivery motion.

Title: Mutagenesis of plasmids in form of gapped circles - by hybridisation with mutagenic oligo:nucleotide, then selective linearisation of non-mutated circles
Inventor: HOFER BERND DR
IPC: C12N15/10
Filed: 1990-07-30
Abstract: Prodn. of a plasmid construct for oligonucleotide-directed mutagenesis comprises; (1) cutting the plasmid at a cleavage site (C), pref. unique, which is outside the region to be mutated, and modifying the site so that it can no longer be closed by a ligase; (2) for a separate portion of the plasmid, cutting out the region to be mutated and isolating the residual plasmid; (3) mixing the modified plasmid from (1) and the residual plasmid from (2), so as to form (by de- and re-hybridisation of the DNA double strand) two partially single-stranded (ss) complementary gapped circles, which contain the region to be mutated in ss form. Also new are mutagenic kits contg. these plasmid constructs. Site (C) is modified by removing the S'-phosphate residue or masking of the 3'-site. USE/ADVANTAGE The use of double-stranded (ds) gaps rather than fluffy ss-molecues shortens and simplifies in vitro DNA synthesis; protects DNA molecules against incorrect hybridisation (which would lead to unwanted mutations), and reduces the chances that the target region for the oligonucleotide becomes masked by forming a stable sec. structure with other ss-molecules. The method can be applied to substitution, deletion or insertion mutations at any position.

Title: Automatic doffer - applies winding data to bobbin for identification and quality control
Inventor: MASAI TETSUJI
IPC: B65H67/06
Filed: 1991-04-09
Abstract: For bobbin quality control, as the fully wound bobbin is taken by the doffer information or data on the rewinding operation is transferred from the winder monitor to the doffer for a constant yarn length. The winding data are applied to the bobbin. The doffer has a mechanism to apply an adhesive label to the bobbin, with the winding data for identification, and the label also secures the yarn end to the bobbin surface. The data are shown on the label in the form of bar codes. The doffer can also apply the identification directly to an end of the bobbin. The automatic doffer (AD) travels along the line of neighbouring winding stations (Wu). A labelling unit transfers data from the winding station to a sleeve (B). The sleeve feed (1) delivers marked sleeves through a continuous conveyor (3) to the automatic doffer (AD). ADVANTAGE - The system gives a bobbin identification to show the winding quality.

Abstract: The invention relates to a motorail train with transport carriages for motor vehicles and passengers, in particular for increased travel and loading speeds. The previous motorail trains do not satisfy the speed requirements, in particular on high-speed routes. The object is to produce a motorail train which corresponds to modern safety requirements and with which the loading times can be shortened. This is achieved in that the train is made up of enclosed transport units for motor vehicles (2), passenger carriages (3) and driving units (1) at the ends, locomotives or control vehicles. The transport units for the motor vehicles (2) consequently consist of a plurality of transport carriages (2a, 2b, 2c) which can be entered by vehicles from the side via gates (6) and which have a loading level which can be driven through in its entirety and an end-side passenger access to the passenger carriages (3), which are coupled distributed between further transport units (2) or to the end-side driving units (1), locomotives or else control vehicles, in particular if the latter have passenger compartments. It is expedient that for this purpose the carriages of the transport units (2), in particular the carriages at the start (2a) and end (2c) of each transport unit (3) have rolling or sliding gates (6a, 6b) on the longitudinal sides, into which the motor vehicles can be driven at an angle from a platform, loading level or loading ramp (38) and parked in the direction of travel of the train. <IMAGE>

Inventor: ROLLWAGE MATHIAS DR
IPC: G01P3/44
Filed: 1991-10-08
Abstract: The description relates to a process for measuring the rotation speed of a rotating component which is completely surrounded by a casing and to a device for implementing said process, in which the current signal generated by the rotating component, after having been suitably processed in digital form, is subjected to two Fourier transformations and the rotation speed is determined from the spectrum obtained following the second Fourier transformation. Here, the rotation speed is found from the time (tx) corresponding to the maximum x of the spectrum, which is directly proportional to the rotation speed n.

Inventor: BECK ERHARD DIPL ING
IPC: B60T8/48
Filed: 1992-01-23
Abstract: A braking pressure control unit, in particular for drive slip control, is based on an antilock braking system that operates according to the return principle. An accumulator (15) is connected by a lock valve (34) to the pressure pipe (6''). The lock valve (34) is opened in particular when a braking process is initiated during drive slip control and regulates wheel slip during braking. To prevent the pressure medium introduced into the braking circuit during drive slip control from returning into the reservoir (34) and damaging the master cylinder packing (13), the accumulator (15) receives a corresponding amount of pressure medium. The packing (13) is thus protected against damage during braking slip control.
