Title: Automatic fabric positioning - uses CCD matrix camera computer system to lay roughly positioned fabrics automatically
Inventor: SIEWERT INGO DR RER NAT
IPC: B25J9/16
Filed: 1990-09-10
Abstract: To position fabric workpieces above and/or beside each other in front of a processing machine, such as an adhesive press, two workpieces are roughly placed at room temp. on a cooled light or warmed dark table, or the separate workpieces are warmed or cooled to be laid on a table at room temp.. The lie of the fabrics is identified by a CCD matrix camera computer system, working in the infra red range, to show the contours and location, or the roughly positioned fabrics on a transparent plate form a shadow which is visible to the CCD matrix camera. The fabric is taken by a gripper plate to the laying table to be positioned individually according to the preset lie stored in the memory, in succession, over and/or next to each other. - The temp. difference between the table and the fabrics is pref. 10 deg.C. The gripper is activated through the camera computer system automatically or manually according to the part contour. On detection of a shift in the contour in one or more workpieces, either the whole lie of the faulty fabric is rejected. On a raised moisture level in the workpieces, the table is cooled.

Title: Selective call signal detector for mobile radio - uses programmable frequency divider to control filter for detection of frequency tone by amplitude discriminator
Inventor: GLOATZ HARTMUT
IPC: H04W88/02
Filed: 1990-11-29
Abstract: The selective calling signal is fed to a frequency discriminator which is set to a predetermined frequency by means of a clock input. The frequency discriminator comprises a switched capacitance filter (7) and an amplitude discriminator (4). The clock rate is set by a microcomputer-controlled programmable frequency divider (12) with a quartz reference oscillator (13). The arrival of the predetermined frequency is detected by the amplitude discriminator and the microcomputer sets the SC filter to a second frequency by causing the frequency divider to output a second clock rate. If the second frequency is also received, the frequency of the filter is reset to the first frequency. The frequency at which the filter frequency alternates between the two settings is used to determine if a selective call has been successfully received. ADVANTAGE - Frequency combinations e.g. for dual-tone calling, may be changed without physical access to circuitry.

Patent DE-4124193-A1 (DE)
IPC: G01P1/10
Filed: 1991-07-20
Abstract: The invention concerns work with a ground compacter driven by a motor protected against exceeding a predetermined maximum rotation speed by means of an overspeed protection control circuit with a speed control range piloted by a speed-dependent setting. It is the purpose of the invention to provide a process which can be implemented by simple means and makes it possible to determine and indicate the current degree of ground compacting attained by the compacter during operation and which provides very precise results, especially at the end of a ground compacting process. This is achieved in that the setting or degree of activity of the control range is detected and converted into a corresponding indication which reflects the degree of ground compacting attained. The drawing shows a part of the motor's ignition system designed to implement the process of the invention. It shows: (1) an ignition transformer with coils (W1, W2, W3); (2) a yoke rotating with the camshaft; (4) the ignition electronics; (6) an electronic subtractor; and (7) a voltage indicator.
Patent DE-4126059-A1 (DE)
Inventor: ERB WOLFGANG DIPL CHEM DR RER
IPC: C08G8/24
Filed: 1991-08-06
Abstract: The binder described is a novolak which can be cured with an ordinary accelerator and which is liquefied by the addition of a reactive liquefying agent in the form of phenol or alkyl-substituted phenols (having side chains containing up to 10 C-atoms). The liquefying agent does not behave like an ordinary solvent, but takes part in the curing of the novolak and is - at least for the greater part - bound into the molecular structure. The invention thus makes a binder available which, in contrast to liquid resols, has excellent storage stability, can be converted easily to anhydrous form, does not have to contain any alkaline components and can be produced simply and reliably.
