Patent DE-3922835-A1 (DE)
Inventor: REINHARD MICHAEL DR ING
IPC: G01N11/04
Filed: 1989-07-11
Abstract: In a process for measuring flow properties of free-flowing media, e.g., liquids, melts and viscous materials, in particular plastics, a measurement sample of the medium is introduced into a measuring cylinder (2, 3, 4) maintained at a given temperature and forced out of the cylinder through a nozzle (33) by means of a pressure piston (54). The fluidity of the sample is determined by measuring properties. A material identification (23) is entered and stored in a computer (7). The computer (7) controls a delivery device (1) and processing devices (17) for the measurement cylinder (2, 3, 4) stepwise so that the measuring cylinder (2) is placed in a charging station (17) where it is filled with the sample by means of a filling device (28, 30, 48, 50, 51). The measuring cylinder (2) is then conveyed to a measurement station (17) into which the pressure piston (54) is slid and a result is obtained by the computer (7) from measurement quantities (e.g., magnitude and duration of the displacement of the piston, nozzle pressure). The delivery device (1) then conveys the measuring cylinder to a cleaning station (17) where it is cleaned by a cleaning device (70, 77). During the next transport stage, it is conveyed to a charging station (17) where it is recharged. The computer (7) associates the material identification (23) input with the measurement result and emits it as a characteristic flow property of the material.
Patent DE-3926251-A1 (DE)
Inventor: URBANSKY RALPH DIPL ING
IPC: H04J3/07
Filed: 1989-08-09
Abstract: A stuffing decision circuit is described which is used in an arrangement for the bit rate adaptation of two signals. It is necessary for the application of the stuffing decision circuit according to the invention that the signal with the higher bit rate is structured in accordance with frames and at least one stuffing decision must be made for each frame. To make the so-called waiting time jitter, which becomes noticeable during the recovery of the signal with the lower bit rate at the receiving end, largely removable, means are provided by means of which the time of the stuffing decision is randomly or pseudorandomly shifted by times which are short compared with one frame length. Due to this modulation of the decision time, the low-frequency jitter otherwise occurring is transformed into higher frequencies and can be easily filtered out by means of a phase-locked loop at the receiving end.

Title: Producing composite castings of light metal clad with copper - by protecting clad layer from oxidn. with protective layer, which is removed by melting during casting
Inventor: GUENTHER BERND
IPC: B22D19/00
Filed: 1990-02-17
Abstract: Producing a composite casting involves a solid cladding layer which is provided with a sealed cover to prevent oxidn. The cover layer must be capable of being melted by the melt of a second material which when cast onto the cladding layer removes the cover together with any casting oxide layer from the surface of the cladding. Pref. in this case of a Cu alloy, pref. Cu-Be cladding layer, a Zn or Zn alloy or Ag alloy oxidation resistant layer is used with a thickness of 10 microns. Layer is located in a mould and heated to a temp. below the oxidn. temp. of the resistant layer. Light metal melt such as Al or Mg alloy is then cast around the layer such that current flow along the surface of the layer removes both the method Zn and any casting oxide which is produced. USE/ADVANTAGE - For clad Al or Mg alloy cast cylinder heads for combustion engines. Oxide free surface of the cladding enables the cladding to diffusion bond to the cast metal and form a good thermal conditions connection.
Patent DE-4006581-A1 (DE)
