Patent DE-2841435-A1 (DE)
Inventor: HOFMANN HORST
IPC: G02F1/133
Filed: 1978-09-22
Abstract: Fiber-shaped metal-containing spacing elements having a well-defined diameter of less than 100  mu m for spacing two plates in an indicia display device, such as a liquid crystal cell, are produced by providing a wire composed of a metal selected from the fourth to sixth adjacent groups of the Periodic Chart of the Atoms, converting the peripheral surface layer of such wire into a brittle metallic compound and breaking-up the so-treated wire into desired size individual spacing elements. By utilizing metal wires, an exact diameter dimension can be attained and by chemical conversion of the wire surface, the produced metal wire loses its ductility and can be easily broken-up into desired size elements. Spacing elements of the invention are useful in all types of indicia display devices particularly in multiplex liquid crystal display devices.

Title: Fourier damping and phase distortion measurement - using zero amplitude test pulse components for minimal system loading
Inventor: BLAESS GERHARD DIPL ING
IPC: G01R27/28
Filed: 1978-11-13
Abstract: A Fourier damping and/or phase velocity distortion pulse measurement circuit ensures both that sufficient individual test pulse components are available for the measurement and that the test piece is not loaded by unnecessary frequency components. This is achieved by setting the amplitudes of partic. harmonics in the Fourier series forming the test pulse to zero. These harmonics may be those having n small values, where n is the order of the series, or those for which alternative signal frequencies occur. The test pulse crest factor, i.e. the ratio of the peak to the effective values, is reduced to a low system loading value by selecting different initial phases for the harmonics making up the test pulse.

Title: Stabilising sewage sludge from clarifying plants - by aerobic breakdown, controlling temperature and nitrite content via air supply
IPC: C02F3/00
Filed: 1978-12-05
Abstract: For the maintenance of a desired temp. in a mass of sewage sludge from a purificn. plant undergoing a process of stability and hygienising, in which the sludge is turned over continuously in a container or a series of containers, in the presence of atmospheric oxygen, the speed a which the air is fed into the container is regulated continuously. The speed of the throughput of air is infinitely variable, whilst alternatively control may be effected by an intermittent feed. The nitrite content of the mass of sludge is measured, and in the event of the overstepp-of a maximal concn., the feeding of air is suspended until a marked denitrification has taken place. Used to exploit the cheaper and quicker process for breaking down the sludge by aerobic bacteria, so as to ensure uniformity in the operation and costs which are economic.

Title: Rotary paper material stamping machine - has shaped cutters on rotating cylinder working together with hard counter element of circular cross section
Inventor: FUCHS SIEGFRIED
IPC: B26F1/44
Filed: 1979-01-12
Abstract: The stamping machine used for the prodn. of paper envelopes, bags or similar items has a rotating carrier cylinder (1) on which cutters (2) of appropriate shape are fitted. During the operation the cutter comes into contact with a circular cross-section-counter element (3) made of ceramic material which is held in place by a clamping strip (4) on the holder (5). The holder is adjustable towards- or away from the cylinder. After the initial setting of the holder amounting to the fraction of the thickness of the material (6) to be cut the holder is tightened in this position. When, after some time the counter element becomes worn the cutting effectiveness is restored by loosening the fixing screws (7) and subsequent slight turning of the counter element.

Title: Contents indicator for waste compressor - shows when container is full and is operated by pressure in hydraulic actuator
Inventor: PAUTSCH GUENTER
IPC: B30B9/30
Filed: 1979-01-22
Abstract: The arrangement is used on waste containers into which the waste material is compressed by a die, which is driven by a hydraulic actuator. The pressure in the hydraulic system is a function of the degree of compression of the material in the container. A pressure indicator is connected to the inlet line of the actuator. A valve, which is mounted in the line which connects the indicator to the inlet line, is closed by a limit switch before the end of the press stroke. The max. pressure is therefore indicated when the container is full with compressed waste material.

Title: Telephone metering system giving detailed individual call data - is for subscribers having access to stored numbers with facility for called number secrecy, using exchange memory
Inventor: DIONYSIOS GYALISTRAS DR
IPC: H04M15/04
Filed: 1980-01-22
Abstract: The additional facility can be applied to electronically managed telephone systems. In the central controller (ZST) of an exchange is a memory (SP) in which is stored details of each called number and call duration made by a subscriber (TN), if the latter has requested this facility. These details are then added to the subscriber's account. In the part of the memory allocated to the subscriber, commonly called numbers can be entered and reselected by the subscriber. To preserve secrecy about numbers called, should the subscriber wish it, but still be able to obtain a detailed account, an extra code can be keyed when selecting a stored number. If such a selection is made then only the address of the number selected is put into that part of the memory assigned to billing. As the number can be erased and re-entered at a different address of the subscriber's selection immediately after a call is completed the actual number called cannot be traced.

Title: Constant rate control for change of process - storing value of start quantity and comparing instantaneous actual data and ramp function data
Inventor: VOGELEI KLAUS ING GRAD
IPC: G05D7/06
Filed: 1980-12-04
Abstract: The industrial process control is applicable where the rate of change of a quantity, e.g. wt., during a filling process, must be kept constant. This is achieved by the use of a ramp-generator followed by a differentiator. The problem of the initial delay due to the differentiator is overcome by measuring and storing the starting quantity value. The required value is obtained from the instantaneous stored value and ramp value. The outputs of the amplifier (3), the ramp generator (4) and the actual value (x1) are fed to the regulator (5) that produces the process control signal (y).
