Abstract: A textile machine for producing cross-wound packages, the machine being equipped with a plurality of workstations arranged next to one another on both longitudinal sides of the machine and having a cross-wound package transport apparatus. The cross-wound package transport apparatus has a first transport device, arranged between the two rows of workstations for conveying cross-wound packages, and a handling apparatus for moving cross-wound packages from the first transport device to the second transport device. The handling apparatus is arranged between the end regions of the first transport device.

Abstract: Method for operating a service unit for processing work orders regarding a cross-wound package/empty tube doffing process employed at spinning machines producing take-up packages that process at least two different lots, whereby the service unit is fed an empty tube via the spinning machine's tube feed track, and the fed empty tube is taken up by the service unit. If the current work order for the cross-wound package/empty tube doffing of the workstations expires before it is processed and the empty tube is exchanged and another work order has come in which is for a workstation requiring a cross-wound package/empty tube doffing for another lot, the already taken up empty tube is released by the service unit, and the service unit takes up an empty tube of another lot in order to be able to carry out a cross-wound package/empty tube doffing process at the other workstation.

Abstract: A textile machine for producing cross-wound packages, which has a plurality of workstations on the two longitudinal sides of the machine and is equipped with a tube magazine arranged at an end of the machine, the tube magazine having a plurality of empty-tube transport rows, driven by electric motor and loaded with empty tubes of different yarn lots. In order to avoid the fixed division of the empty-tube transport rows that hitherto was defined by the construction of the tube magazine and thus to avoid limited variations in the yarn lot management, the invention provides for the empty-tube transport rows to be equipped with electric drives, which are connected to a control unit of the textile machine, the machine control system being designed in such a way that different lot management programs are set by software.

Abstract: A method and an arrangement for filling a second storage container with compressed hydrogen or helium from a first storage container are described, wherein the first and the second storage containers are connected via at least one line, in which at least one valve is disposed. According to the invention, a switching valve (b, b?, b?) controlled by its own medium or a foreign medium is used as a valve, wherein the set pressure of the switching valve (b, b?, b?) is fixed by the maximum permissible operating pressure of the second storage container (B, B?, B).

Abstract: A device for the pressure reduction of a pressurized medium, wherein the medium is supplied to a consumer or system, which is connected downstream, after a pressure reduction has taken place and the consumer or the system, respectively, encompasses a specified design pressure. Provision is made for two pressure regulators connected in series, as well as for corresponding valves, which serve for the pressure reduction of the pressurized medium. A mobile transport device, which encompasses such a device, is further proposed.

Abstract: The invention refers to a cell free assay for determining the activity of a Na+/Ca2+ exchanger (NCX) protein by means of a cell free electrophysiological sensor chip, a kit of parts comprising the sensor chip with a NCX protein as well as the manufacturing and use of the kit of parts.

Abstract: The invention relates to a device for electrophoretically separating molecules. The inventive device comprises: at least one plate having a top side and an underside; a first separating channel provided for receiving at least one first separating medium; at least one second channel, which is orthogonal to said first separating channel and which is provided for receiving a second separating medium; optionally comprises implements provided for filling the device with reagents, solvents, buffers, separating media and/or for loading the device with a sample to be separated, and; terminals for applying electric separating voltage to the separating channels. In the device, the first separating channel is located on the plate top side and comprises at least one first opening that leads to the plate underside, whereby the second separating channel is located on the plate underside and comprises at least one second opening.

Abstract: A method for producing an effect yarn on an open-end rotor spinning machine, formed from an alternating line-up of yarn sections and effects consisting of pre-determined thickenings, wherein an effect is produced where the yarn is joined by means of a piecing end, in the piecing region of the yarn located downstream of the piecing end, following a break in the thread. The quality of the yarn produced in this way is improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piecing regions, are eliminated.

Abstract: A rotor spinning machine of the type comprising a plurality of working stations and a bobbin supplying device extending along the machine, wherein at least two service units supplying the working stations with bobbins are supplied by the supply device and wherein the rotor spinning machine comprises a control device for controlling the service units. The control device is configured in such a way that it suppresses a subsequent bobbin request from the second service unit in the event of an existing bobbin request from the first service unit positioned downstream in relation to the transporting direction of the supply device, until the initially existing bobbin request has been fulfilled.

Abstract: The aim of the invention is to produce an effect yarn on an open-end rotor spinning machine, formed from an alternating line-up of yarn sections and effects consisting of pre-determined thickenings. To this end, an effect is produced where the yarn is joined by means of a piercing end, in the piercing region of the yarn located downstream of the piercing end, following a break in the thread. The invention enables the quality of the yarn produced in this way to be improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piercing regions, are eliminated.

Abstract: A method of winding the yarn traveling at a work station of a spinning bobbin winding machine or of a bobbin winding machine from a yarn source onto a take-up bobbin (4). After each yarn interruption, the yarn end is unwound from the take-up bobbin (4), a yarn joinder reconnects the yarn source and the take-up bobbin (4) and the winding process is then continued if a tolerable yarn joining location is present. Upon the occurrence of each yarn interruption, the amount of yarn wound since the last yarn joinder is determined. If such amount of yarn is determined to be less than a predetermined amount of yarn, a sufficient amount of yarn is unwound and separated from the take-up bobbin (4) to include the last-occurring yarn joining location in the separated yarn section. This results in an optical improvement in the quality of the finished textile product.
