An autoleveller draw frame achieves changes in the draft by changing the supply speed. The can press nevertheless works evenly. A storage device between the sliver calenders and the can press compensates for changes in the amount of supplied sliver. The storage device can be arranged in such a way that it allows a "flying change of cans." In one aspect, between the sliver calenders and the can press, the sliver forms a hanging loop which varies in depth, depending upon any changes in the supply speed of the sliver, while the can press operates relatively evenly and is not required to be accelerated or braked in response to changes in the supply speed. In another aspect, the storage device includes a conveyor belt arrangement between the supply of the sliver and the can press. Sliver loops are formed on an upper conveyor belt strand, whereafter they are deflected to a lower conveyor belt strand and then fed to the can press. The can press stretches the sliver loops on the lower conveyor belt strand as the sliver is received in the can. During a short period of time during the changing of cans, the sliver is no longer stretched on the lower conveyor belt strand, but is allowed to be maintained in loops, which represents an increase in the amount of sliver maintained at the storage device during can changing.

A combing head comprises carrying and drive rollers for the lap roll, a cylinder, a detaching roller pair and nippers reciprocable between a drawn-back position and an advanced position. When the trailing end of the lap material runs off the winding tube, the combing machine is stopped at a time after the detaching roller pair have detached a fringe from the lap in the nippers and after the fringe has been separated from the lap. The lap trailing end and the empty winding tube are then removed and a new lap roll is placed on the carrying and drive rollers. Lap material is unwound from the new lap roll until the start of the lap has passed beyond the nip line of the nippers. The combing machine then restarts. The method can, if required, be performed substantially or completely automatically and calls for only a short machine down time.

The invention relates to a flow restrictor (1) for restricting a volume flow through a liquid line, said flow restrictor comprising a support (10) having a passage and a bent flat spring (11) attached to the support (10). The flat spring (11) comprises at least one spring tab (12) and the passage at least one opening (13), the spring tab (12) and the opening (13) having a substantially identical extension along a longitudinal direction. The spring tab (12) is designed and arranged above the opening (13) in such a manner that it increasingly rests against the support (10) with increasing differential pressure, thereby gradually making the opening (13) smaller and continuously reducing the passage within a defined pressure range. The dimensions of the opening (13) are adjusted corresponding to the size of the spring tab (12), thereby allowing a compact flow restrictor (1) which is less susceptible to dirt. The continuous reduction of the passage allows an increase in vibration resistance of the flow restrictor (1).

The invention relates to a process for whole-grain conditioning, in particular of native and malted brewing cereals. To improve the mashing process and to increase the number of brews and product quality, the brewing cereals are conditioned and subsequently fed to a hulling and/or mechanical comminution process.

An individual regulation circuit is provided for each position-regulated drive motor for a textile machine, such as drafting arrangement. It is contemplated by the invention to have each such regulation circuit encompass a position sensor which also can deliver a position signal during standstill of the motor shaft of the associated drive motor.

A ring spinning machine comprises at least one group of spinning stations or points (11) arranged adjacent each other at equal intervals, a bobbin change device (14) for simultaneous replacement of full bobbins (15 ) spooled with yarn by empty bobbins (16) at each spinning point (11) and an endless conveyor (17) which extends along the spinning points (11) and is led from one end of the spinning point group (12) to the other back on itself and on which at the interval of the spinning points (11) upright bobbin pegs (13) are arranged in such a manner that in a bobbin change position of the endless conveyor (17) each spinning point (11) is exactly aligned with a bobbin peg (13) associated individually therewith. Each bobbin peg (13) is arranged on its own peg support tray (18). Associated with each peg tray (18) is a driver (19) which is adapted to be brought into entraining engagement therewith and which is disposed on the endless conveyor ( 17) in such a position that when the driver (19) is in entraining engagement with the associated peg tray (18) the bobbin peg (13) of said peg tray (18) in the bobbin change position of the endless conveyor (17) is exactly aligned with the associated spinning point (11).
摘要:
For the purpose of balancing (S3) a group of consumers in a fluid transport system in which each consumer is configured with a motorized regulating valve for the purpose of regulating the flow through the consumer, characteristic data for the consumer is saved (S2) which determines a valve position of the corresponding regulating valve for the target throughput through each consumer. A momentary total throughput through the group of consumers is determined (S32) by means of a common throughput sensor, and based on the momentary total throughput and a sum of the desired target throughputs through the consumers, a balancing factor is determined (S34). By setting (S31) the valve positions of the corresponding regulating valves based on the characteristic data and the balancing factor, a dynamic balancing of the consumers is carried out.

A method of preparing flour or splits of legume according to the invention comprises the steps of: i) providing legume; ii) allowing the legume to partially germinate; iii) optionally, terminating germination of the legume; iv) preparing the partially germinated legume for milling; v) optionally, milling the prepared legumes of step iv). Partial germination was found—besides increasing the content of nutrients and decreasing the content of antinutrients to enhance the physical quality of splits and to enhance the dehusking yield. Moreover, nutritionally more beneficial flour and splits can be provided.

The invention relates to a method and a system for dehusking grains, in particular for removing the spelts and/or the seed coat and the germ bud of grains and/or of malted grains and its processing in the brewing industry. The outer layers/shells are removed from cleaned and malted distiller's grains in a husking machine.
