Patent DE-4002152-A1 (DE)
Inventor: HEGENDOERFER MAX DIPL ING
IPC: H04M1/2747
Filed: 1990-01-25
Abstract: Modern subscriber terminals, e.g. featurephone, MultiTel and modern ancillary devices, normally offer a whole range of facilities to make them easier to use. To simplify the communication process, these devices usually contain a digital memory for data, in particular for telephone numbers, names, addresses etc., where the contents of the memory can either be shown visually on a display or can be output in audible form. To enable the data transmitted via the telecommunication network to be stored automatically, even during the temporary absence of the subscriber, and to be read out in simple fashion by the called subscriber, a buffer memory is disposed in the subscriber terminal. A control device compares the telephone number in the buffer memory with those in the memory and, if the telephone numbers coincide, the data allocated to this telephone number are read out from the memory and are also stored in the buffer memory. By pressing a button, the subscriber can retrieve in succession the data stored in the buffer memory, e.g. telephone numbers, and use them for automatic call set-up. The new subscriber terminal enables the representation of any temporarily stored messages in surprisingly simple fashion and can be used in differently configured communication networks for switched connections. <IMAGE>

Title: Thread feeding mechanism - for sewing machines with two non-contacting-rollers  for min. hold-back forces
Inventor: ENGEL GERHARD
IPC: D05B47/00
Filed: 1990-02-13
Abstract: Sewing cotton or band is supplied to a sewing machine by not contacting rollers which the thread encricles in an S-curve with a large angle of contact.

Abstract: PCT No. PCT/DE91/00376 Sec. 371 Date Jan. 6, 1992 Sec. 102(e) Date Jan. 6, 1992 PCT Filed May 8, 1991 PCT Pub. No. WO91/18148 PCT Pub. Date Nov. 28, 1991.Pigments for the papermaking industry, in particular kaolin, are treated with a high molecular polymerizate that is solvated by means of carboxylate groups and belongs to an ethylenically unsaturated, radically polymerizable carboxylic acid as the binder. By gradually adding an acidifying agent the binder is coacervated and totally precipitated on the pigment. It is important that the quantity of the acidifying agent is limited in such a manner that the pigment retains a negative surface charge and the coacervate still contains water. With the pigment treated thus printing papers with increased pigment content and/or increased breaking strength can be manufactured.
