Title: Line termination
Inventor: KUKE RUDOLF
IPC: H04M3/30
Filed: 1983-02-03
Abstract: The invention relates to a line termination for telephone lines connected in parallel with a telephone set having an electric or electronic component which identifies a test voltage threshold lying above the operating voltage of the telephone network, according to patent... (patent application P3148740). By means of the present invention, this line termination is intended to be put to a further advantageous use in conjunction with telephone sets whose ringers can be de-activated but which are nevertheless to remain connected to the telephone network and are thus to remain on call standby. This object is achieved according to the invention by allocating the ringer of a telephone set to the line termination in such a way that the ringer or the line termination can be connected via a changeover switch to the connection line as required.
Patent DE-3304529-A1 (DE)
Title: Hydraulic control device
Inventor: GROB ALFRED
IPC: F04B49/10
Filed: 1983-02-10
Abstract: The manipulating valve, which serves, for example, to unload a pump (18) when it has supplied a consumer, has a pressure-relief valve (26) with which an unloading-valve body (36) is connected in series. A control spool (40) is arranged coaxially to the valve body (36) in a longitudinal housing bore (11). The control spool (40) is loaded on the one side by the pressure in a space (51) and by a spring (50) and on the other side by a spring (37) which is supported on the valve body (36). Two choke points (46, 49) are formed in series in the spool on the path from the pressure-relief valve to the space (51). The choke point (49) has an especially narrow cross-section of flow owing to the fact that a pin (44) projects through it in every position of the control spool. In this way, a greatly delayed movement of the control spool can be achieved without the risk of contaminating the narrow choke point by foreign bodies, since this choke point is always mechanically cleaned. By a displaceable abutment for the control spool, a time delay with regard to its response behaviour can be achieved. <IMAGE>

Title: Method of fabricating finely patterned photoresist films on a substrate
Inventor: NAKANE HISASHI
IPC: G03F7/32
Filed: 1983-06-15
Abstract: The invention relates to a method of producing very finely patterned photoresist layers on a substrate surface by a special combination of a photoresist composition with a developer. The developer is used to develop the latent image in the photoresist film after exposure to actinic radiation through an image pattern. The serious problem of swelling of the image pattern lines of the photoresist can be minimised by the developer solvent. The best results are achieved by using a photoresist composition based on a polymer of methyl isopropenyl ketone as basic polymer and an azide compound as photosensitive component, and a developer solvent selected from ketone compounds, nitroparaffin compounds and monoalkyl ethers of polyhydric alcohols such as ethylene glycol or corresponding acetates.

Patent DE-3347271-A1 (DE)
Title: Optical device on motor vehicles
Inventor: WIESMEIER ALBERT DR
IPC: G02B5/28
Filed: 1983-12-28
Abstract: In an optical device on motor vehicles, which serves the purpose of reflecting graphically represented measurement or warning signals into the field of view of the driver, there is provided on the windscreen a partially transparent mirror, which is constructed as a dielectric multiply laminated arrangement and on which the light emanating from the observation object, a pattern generator accommodated in the instrument cover, is reflected at the Brewster angle  alpha p. Arranged between the semi-transparent mirror and the observing light, when seen in the direction of propagation of the flux of observing light, is a circular polariser which comprises a linear polariser on the mirror side and a 2/4 plate on the object side. The circular polariser is orientated over all in such a way that its linearly polarised output light flux is polarised vertically with respect to the plane of incidence of the flux of observing light. The image of the respective signal pattern that is reflected into the field of view of the driver is very contrasting, since the reflection factor of the useful light at the semi-transparent mirror is very high, and a disturbing defect due to optical reflections occurring in the observation space is suppressed by the circular polariser.

Title: Process for upgrading low-grade coal
Inventor: GREENHILL EDGAR BRENT
IPC: C10F7/00
Filed: 1984-02-08
Abstract: A process for upgrading low-grade coal is proposed, which comprises grinding the low-grade coal to a degree of fineness at which at least 40% pass through a screen having an open mesh width of 0.053 mm and is sufficient to destroy the cellular structure of the coal. Water is added to form a suspension of the coal. Fibrous materials and/or non-fibrous chemical binders are added to the coal suspension before or after it is formed. The suspension is sun-dried and lifted at a time when the coal has a moisture content corresponding to its plastic (or deformable) state. If necessary, the moisture content of the coal is occasionally increased in order to ensure a consistency favourable for the extrusion and/or forming of the coal and for the dimensional stability after extrusion and/or forming. The coal is then extruded and/or formed (unless this has already been done during lifting) and then dried in the sun or under controlled conditions.

Title: Reloading method for digital instantaneous sound curve values in a computer-controlled electronic musical instrument
Inventor: SCHADE GUENTER DIPL ING
IPC: G10H7/00
Filed: 1984-03-26
Abstract: Improvement of a method for electronic music production in which sound signals and therefrom one or more music signals are produced using digital methods, based on digitally stored wave forms which are also referred to as sound curves or sound signal sequences,   - said sound signal sequences for all sounds being stored in a common, continuously addressed memory, and - a device referred to as a sound channel memory being used for buffer storage of the current and subsequent instantaneous amplitude value and of further values for each sound signal.   The improvement concerns the reloading of the sound channel memory from the sound signal sequence memory. A conveyer belt is inserted as a buffer between the sound signal sequence memory and the sound channel memory, and comprises at least     - a prompt stage  (data from the sound channel memory pass on to the conveyer belt),   - a memory access stage (data from the conveyer belt pass on if necessary to the sound signal sequence memory, whereupon data from the sound signal sequence memory pass back to the conveyer belt),   - a write stage (data from the conveyer belt pass on if necessary into the sound channel memory), but may also, if necessary, comprise further (empty) stages. This conveyer belt is operated with a fixed shift timing. Advantageous further developments relate to refreshing the sound signal sequence memory.

Title: Excavator-protected, electrically insulated wall bushing for domestic pipeline inlets
Inventor: WALZ GEORG
IPC: F16L5/02
Filed: 1984-03-29
Abstract: The invention relates to an electrically insulated, excavator-protected wall bushing for domestic pipeline inlets, especially for domestic gas pipe inlets, which is flexible to a limited extent and can be fitted subsequently. The excavator protection is achieved by means of an external collar (4e) which is mounted on the bushing pipe (4) and projects radially between two insulating rings (6, 7) which are arranged in an insulating chamber (1c) through which the bushing pipe passes in an electrically insulated manner, this insulating chamber, which is closed at one end by means of a screw closure (3), being in each case integrally connected to a supporting plate (1a) which can be mounted on the inner side of the wall and to a protective pipe (1b) which engages around the bushing pipe in an electrically insulated manner and can be cemented in the masonry. A damaging excavator pull or push exerted on the pipeline which is laid outside is transmitted by means of the external collar of the bushing pipe to one of the two insulating rings and from said insulating ring via the insulating chamber to the supporting plate, and is subsequently absorbed by the building wall. The wall bushing according to the invention is of particularly simple construction and can be installed in a fully assembled state in a new structure, or can be installed subsequently in an already existing building. <IMAGE>
