Patent DE-4341731-A1 (DE)
Title: Bobbin sleeve cleaning
Inventor: REUTERS HANS-JAKOB
IPC: B65H73/00
Filed: 1993-12-08
Abstract: To clean bobbin sleeves placed on bobbin carriers, a sleeve monitor (24) sends data to a control (27) on the dimensions and location of any residual yarn winding (72) still on the sleeve (41). The control (27) activates the sleeve stripper according to the measured data. Also claimed is an assembly with a sleeve monitor (24) at the distribution path (9), to measure the dimensions and location of any remaining wound yarn (72) on the sleeve (41). The monitor is followed by a cleaning unit (26) which gives a defined movement to the stripper tool to take off the residue. The monitor (24) and cleaner (26) have a functional interconnection between them.  Pref. the control (27) operates the cleaner (26) so that the stripper tool is directed to the portion of the sleeve (41) where remaining yarn (72) is still in place. The control (27) assesses the data from the monitor (24) according to the condition of the remaining wound yarn (72), as to whether it can be unwound or not, to direct the sleeve (41) to different cleaners (26).  The system ensures that the sleeves are wholly cleared of any wound yarn before they are returned for further use.

Title: Electronic bath-tub/shower fitting
Inventor: DESCH KURT MICHAEL DIPL ING
IPC: E03C1/10
Filed: 1994-08-30
Abstract: The invention relates to an electronic tub/shower fitting which is preferably arranged, as bath-tub fitting, beneath the bath-tub border between the tub rear side and the tile facework thereof; a system separator being integrated into the fitting in order to prevent service water from being taken back in, in particular via the combined tub inlet/overflow located on the upper tub border. The known solutions make use of three actuating motors per fitting: hot water, cold water and changeover means; very expensive proportional actuating magnets are also used instead of the actuating motors for hot water and cold water. The above applications, excepting DE 3909559 A of the applicant, do not have an integrated guard against water being taken back in. The object of the invention is to provide an electronic bath-tub fitting, to be produced in a satisfactory manner by injection moulding, which is designed such that it can be encased exclusively beneath the bath-tub border, within the tile facework of the tub. The fitting, including the diaphragm valve, is driven, entirely, preferably by only one standard motor/gear mechanism actuating unit with a reversible stepping motor. <IMAGE>
