Title: Alkaline metasilicate prod. used in glass mfr. - made from caustic soda, water and sand, and used as replacement for expensive sodium carbonate
Inventor: SCHUMACHER LEO DIPL ING
IPC: C03C1/02
Filed: 1979-07-02
Abstract: The prod. contains by wt. 53-55% Na2O, 24-35% SiO2, and 12-21% CO2; and the pref. prod. consists of a flowable, homogeneous mixt. contg. 50-70% of a metasilicate phase Na2SiO3, and 30-50% soda(Na2CO3). The prod. is pref. obtd. starting from a mixt. of 80-85% of NaOH lye (30%) with 8-13% silica or sand. The mixt. is held 20 mins. at 250 deg.C, then cooled to 100 deg.C in a pressure vessel and 4-8% CO2 at 30-40 bars added. After heating 10 mins. at 150 deg.C the prod. is cooled.

Title: Alarm indication signal recognition circuit - connects digital signal from transmitter to first input of NOR-circuit, whose output goes to counter input
Inventor: ROEHRBEIN ROLAND
IPC: H04J3/14
Filed: 1979-07-21
Abstract: The alarm indication signal to be recognised is distorted by bit defects and appears instead of a digital signal, while the circuit also recognises the drop-out of a digital signal despite appearing interference pulses. The digital signal (J1) from the transmitter is supplied to the first input of a NOR-circuit (01). The latter output is coupled to an input (Cp) of a counter (Z1), whose output is coupled to the D-input of a flip-flop circuit. The clock pulse (Tp), determining the measuring time periods, is connected to the clock pulse inputs of two flip-flop circuits (D - FF1, D- FF2), as well as to the input of a delay stage (T). The latter output is coupled to the inputs of two counters (Z1,Z2). The decoded and inverted digital signal (J2) lies at the first input of an AND-circuit (U), at whose second input lies the clock pulse derived from the digital signal (J1). The AND-circuit output is connected to further logic circuitry for obtaining the PCM signal drop-out criterium.
Patent DE-2931528-A1 (DE)
Inventor: SCHMOLL SIEGFRIED DIPL ING
IPC: H04M11/08
Filed: 1979-08-03
Abstract: A circuit arrangement for identifying a test signal in a videotex modem has a pulse former stage (IF) with a sub-stage (ZIO) connected downstream whose output signal serves to synchronise a circuit (92, FF1, FF2) in order to generate a comparison pulse string (V) which is applied to the D-input of an RS flip-flop (FF3) to whose clock input the test signal is applied. A counter (Z14) counts the test signal pulses but is reset by the output signal of the flip-flop (FF3) if a pulse does not occur within the time slot defined by the width of the pulses of the comparison pulse string. When the counter (Z14) reaches its final position, i.e. when the test signal has been correctly identified, the output signal of the latter triggers a second RS flip-flop (FF4) at whose output a signal (M) for successful testing appears. <IMAGE>

Title: Rubber sealing ring between pipe ends - has protrusion fitting over step on male pipe end
Inventor: SCHIFFNER HERMANN
IPC: F16L21/035
Filed: 1979-10-13
Abstract: The sealing ring, of rubber or similar elastic material, is for use between pipe ends fitting one inside the other. The male end has a peripheral step formed by reducing the external diameter, while a mating internal step is formed inside the female end. The outer diameter of the male end is less than the internal diameter of the widened female one. The ring (1) has a nose-shaped protrusion (2), whose distance (A) from the lower face (3) of the ring is equal to half the difference between the full-and reduced diameter portions of the male end. Thus when the ring is slid over the reduced- diameter portion, the protrusion fits over the step.

Title: Fluidised bed steam generator system - dries brown coal using combustion gases leaving generator, fed to bed from below
IPC: F23C10/00
Filed: 1979-12-01
Abstract: The steam generator operating system utilises fluidised-bed firing, with combustion air and finely divided brown coal being fed in from underneath. The brown coal is dried by the combustion gases leaving the steam generator, with the gases cooled to their maximum permissible final temperature in the process. The brown coal is also used to clean the gases, at least partly, while the current of brown coal and gases can be passed through a pulverisation stage. The cooled gases can then be separated from the pulverised brown coal and directed into a chimney, the coal being mixed with combustion air and delivered to the furnace fluidised bed.

Abstract: A system entering instructions and/or data is esp. for computers fitted in vehicles. It enables the driver to feed in instructions or data without distracting his visual attention from the course of the vehicle etc. This is achieved by using a microphone (10) for acoustic data input. The signal series generated by the microphone are compared in an evaluation circuit (11 to 25) with stored signal series and a corresp. correlation arrived at. The evaluation circuit contains a selection device (20) which associates with the input signal series the stores signal series most similar to it.

Title: Electrophotographic film copier suitable for microfilms - automatically rewinds at end of each sequence to prevent blank spaces after pauses
Inventor: JASKOWSKY JOERG DIPL ING DR
IPC: G03B27/52
Filed: 1980-08-02
Abstract: A mark is applied at the end of each series of exposures by a marker (10) after the charging position (2) and before the exposure position. This mark is identified by a detector (6) after the thermal fixing point (9) to switch off the process cycle and stop the film feed. The film is then automatically rewound to the original marking position and held ready for the next sequence of exposures. The control enables the electrophotographic copy process, for microfilms etc. to be operated as a continuous feed, without having blank spaces and wasted film due to meal breaks etc. A simple control interlocks the different process stations when the copy process is restarted.
