Title: Automatic two-for-one twister doffer - stores stations with yarn breaks in its memory to ignore those stations and only visit points where doffing is required
Inventor: SUZUKI TADASHI
IPC: D01H9/04
Filed: 1991-05-14
Abstract: The control (3) for the mobile doffer to service a row of two-for-one twisting stations, to give an automatic exchange the supply and winding bobbins, stores the loaction of a twisting station where a yarn break has not been repaired, and that that a further visit by the doffer (2) is not required.  As the doffer (2) approaches the twisting station (1), the control (3) directs it to travel past without stopping as long as the twisting station (1) is out of action for the same reason. ADVANTAGE - As the doffer is directed past stations where there is a yarn break, and concentrates on stations where its doffing action is required, the productivity of the assembly increases.

Title: Wind energy extraction aerofoil - has trough-shaped front sheet and flatter rear sheet leading into trough at front end
Inventor: RABAN VON CANSTEIN CARL-MAGNUS
IPC: F03D3/06
Filed: 1991-06-25
Abstract: The aerofoil has at least two coupled sections of differing dynamic functionality, the one supporting the other in order to convert a wind flow into useful energy.Flows from each direction of a horizontal plane are converted into a circulatory flow of at least 270 deg. around the vertical axis of the individual foil sections. Flow from behind rather than from the sides circulates in the trough formation producing a drive force, whilst a flow from the sheet-section passes straight through. On the other hand, when the flow is more from the sides forwards at least 45 deg. right and left of the functional direction of the flow receptor, this leads to a typical lifting airflow. USE/ADVANTAGE - To maximise the use of wind energy in various applications.

Patent DE-4219541-A1 (DE)
Inventor: SCHOENMEIER HERBERT
IPC: B65H18/20
Filed: 1992-06-15
Abstract: Machines for winding continuous strips of material (5) on spools (6) exist which have two support rollers (1, 2) against which the winding rollers (4) rest during winding, the strip of material (5) being fed from below through the gap between the support rollers (1, 2) so that it passes round part of one support roller (1). When the winding rollers are changed, a cutter (14) with a cutter blade (15) is moved upwards through the support-roller gap into the roller bed (3) in order to cut off the strip of material (5). In order to reduce the weight of the winding rollers (4) resting on the support rollers (1, 2), an air chamber (8) with a compressed-air supply (9) is located in the lower angle between the two support rollers (1, 2). The air chamber (8) extends over the whole working width of the rollers, sealing off the gap between the support rollers (1, 2), and has an air-outlet slit (11) allowing air to pass into the gap. The invention calls for the cutter blade (15) to be mounted on a support rod (18) which is located in the air chamber (8) and can be raised and lowered, thus raising the cutter blade (15) through the air-outlet slit (11) into its cutting position in the roller bed (3) and completely retracting it into the air chamber (8).

Patent DE-4313508-A1 (DE)
Inventor: STUMP GABOR
IPC: G08C15/12
Filed: 1993-04-24
Abstract: An improvement is proposed for a machine which consists of a basic assembly (1) and a tool (3), the transmissions of an analog or a digital information from the basic assembly to the tool being carried out by means of pulse-width-modulated voltage. At the same time, one or more analog or digital items of information can be sent back from the tool (3) to the basic assembly (1) in the form of a current which has been decoupled from the pulse-width-modulated volage. The advantage of this bidirectional data transmission is the high degree of freedom from interference and the insensitivity in terms of thermal influences. As a result, reliable data transmission is made possible under extreme conditions, such as they can be encountered for example in welding technology. <IMAGE>
