Patent DE-2949806-A1 (DE)
Title: Fast digital filter suppresses random interference pulses - by taking majority verdict of numerous instantaneous valves of binary signal, esp. for machine monitoring
Inventor: RUMOLD GERHARD
IPC: H03K5/1252
Filed: 1979-12-11
Abstract: The digital filter writes the instantaneous value of the incoming binary signal several times into appropriate cells in a digital memory. The memory is read at a clock rate selected for the transmission of the filtered binary signals. The state of the filtered signal being transmitted is determined by the majority of read instantaneous values. Only the written-in instantaneous values of the binary signal are read. During reading, an uncritical state ('O') of the filtered signal (X) is generated whenever a given number m of the n read instantaneous values is in the uncritical state ('O'). The instantaneous values remain in their storage cells until read.

Title: Automatic exposure microfilm camera - has processed print measured by scanner and enables incorrect exposures to be repeated, using digital display of process
Inventor: WELP ULRICH DR
IPC: G03B27/74
Filed: 1980-01-21
Abstract: A microfilm camera (6) with automatic exposure control monitors the exposed and processed film, frame by frame and prepares a mean density reading which is compared with a reference value. A digital display (17) indicates if the exposure is successful, and if not what correction is being made to the exposure. A microcomputer controls the whole machine, and operates the exposure corrections to generate optimum prints. The control has a memory which stores the different frames so that if a frame is subsequently found wrongly exposed then the original can be retrived and a corrected exposure made. The density scanner plots a set pattern over the print and the microcomputer calculates a mean density value.

Title: Stabilising arch joint linking heels to front of footwear - has two side bar sections leaving heel area free for improved comfort
IPC: A43B23/22
Filed: 1980-02-07
Abstract: The joint which forms the bridge between the heel and ball of the shoe to provide the required arch of the shoe is in two sections (2,3) which are set in the sides of the shoe. The two joint sections are pref. joined by a curved cross connection piece (4) into one structural unit. This design of the joint maintains the resilience, cushion effect and pliability of the sole since the heel area is free of fillers or parts of the joint so that further foam layers are unnecesary. The shoe can be worked onto a lightweight comparatively thin welt with further reinforcements also unnecessary. Sewn-in uppers can be worked directly onto the soles of the heels, of special importance in the manufacture of sandals.

Title: Synchronisation of TDM telecommunications network - using coupling of information signals of lower bit rate into multiplex channel via corresponding stages
Inventor: SCHMITZ JOHANN DIPL ING
IPC: H04J3/06
Filed: 1980-04-24
Abstract: The network has a central office for a large number of channels and several outer stations for smaller number of channels. These outer stations are arranged along a connection path and coupled to it in parallel. The total of useful channels of all outer stations equals the number of central office channels. Direct signal connection is established only between the latter and the outer stations. Both the central office and the outer stations each have a transceiver, synchronised by the central office transmitter. The clock pulses and synchronisation signals from the most distant outer station are transmitted to the central station in succession via the other outer stations for their and the central office receiver synchronisation. For transmission of signals which are bundled in hierarchy stages into a single multiplex signal the coupling of information signals of lower bit rate takes place into the multiplex signal via a number of stages corresponding to the hierarchy stages.

Title: Temp.-controlled heating system for railway points - heats entire points or only switching location according to precipitation level
Inventor: HAUSDOERFER BERND DIPL PHYS
IPC: E01B7/24
Filed: 1980-08-04
Abstract: The automatic switching circuit for the heating system uses a thermistor, a resistance thermometer or a thermoelement as a temp. sensor. A cold and snow detector responds to the temp dropping below 1 deg. C, or to snow falling, to energise the voltage supply for two threshold switches associated with a heated humidity sensor and a temp. sensor. These allow the points heating to be switched on when the temp. drops and the precipitation is present and allow heating of only the switching location to be provided when the temp. drops without precipitation. Pref. a temp. sensor directly attached to the rail is used to cut off the heating when the rail temp. rises above freezing point.

Title: Burning of combustible matter in bulk material - esp. where resin binder in used foundry sand is burnt in fluidised bed using air
Inventor: CEBULLA DIETRICH DIPL ING
IPC: B22C5/08
Filed: 1980-08-29
Abstract: The bulk material is continuously fed into a first bed, which is fluidised by air to burn the combustible matter (I), leaving a non-combustible material (II). The bed is heated by the calorific value of matter (I), and possibly by adding a fuel. The hot gases obtd. from the first bed are fed through a heat exchanger, used for the indirect preheating of the bulk material before it enters the first bed. Material (II) leaving the first bed is fed into a second bed which is fluidised by air; and this air is preheated in cooling material (II). The hot air thus obtd. is used in the first fluidised bed. Material (II) is pref. used foundry sand contg. a resin binder (I). Used foundry sand can be continuously reclaimed and used instead of new sand. The process requires a relatively low amt. of energy and does not pollute the environment.
