Patent DE-2947600-A1 (DE)
Title: Electronically-controlled telephone exchange - has main computer and subordinated micro-processors regulating sections of exchange including number selection
Inventor: SCHWARZ GUENTER
IPC: H04Q3/545
Filed: 1979-11-26
Abstract: The control arrangement uses the microprocessor (SGP) that manages a section (00-30) of the exchange, for number generation and transmission functions. Use of the main computer (CC0, or provision of special equipment, is thereby avoided. The order for a number and its allocated section (00-30) is entered into a memory (ASP) by a main computer instruction. The processor checks this memory cyclically. If an instruction is present it commences the pulse formation, 60ms pulse and 40ms pause, and places such a pulse into an output unit (I/Os) from which it is released at a rate and instant determined by the clock associated with the computer (CC). From the designated section (00-30) the signals are sent out to the receiving exchange. An auxiliary store (ZS) records the pulses sent out, or, alternatively, the pulses still to be sent. This information is also checked cyclically by the processor in the number generation routine. On completion of the number the processor cancels the instructions in the memories (ASP,ZS). The memories (ASP,ZS) may form part of a multipurpose memory (M) associated with the other functions performed by the processor.

The end products are intended for use in cellular therapy. The products are suitable for prolonged storage without any loss in activity.
Patent DE-2948785-A1 (DE)
Title: Vertical synchronising signal detector circuit - stores synchronising pulse for use if transmitted signal falls out in e.g. video recorder
Inventor: KOBAYASHI MASAHARU
IPC: H04N5/10
Filed: 1979-12-04
Abstract: A vertical synchronising signal detector receives a synchronising signal mixture of horizontal and vertical components. This incoming signal controls a pulse generator which generates a timing pulse having a period of half the horizontal synchronising pulse and delays it by a quarter period. The timing pulse control a vertical signal extractor circuit which also receives the signal mix, and compares the vertical synchronising signal with a reference signal. An output impulse is generated when full coincidence is detected. The output signal from the extractor is fed to a comparator with the timing pulse and on coincidence of the two a vertical synchronising signal impulse is generated and also stored. If no vertical synchronising signal is received the stored signal is sent out on receipt of the timing pulse. In this way transiently defective vertical synchronising signals e.g., due to scratches or dust, are replaced without loss of picture quality.

Patent DE-2951130-A1 (DE)
Inventor: BAUDIS ULRICH DIPL CHEM DR
IPC: B22D31/00
Filed: 1979-12-19
Abstract: For removing and dissolving sand mold residues from cast parts, particularly sand mold residues containing zirconium oxide and titanium oxide, there have previously been used mechanical and electrochemical processes in salt melts. However, these processes are very expensive, attack the surface of the cast pieces or fail to work with sand mold constituents which are difficult to dissolve. These disadvantages are avoided by inserting the cast parts having adhering sand mold residues into a melt of 55 to 97 weight % of alkali metal hydroxide and 3 to 45 weight % of one or more fluorides of an element of the first to third main group of the periodic system of elements and/or zinc at 400 DEG  to 900 DEG  C. Preferably the salt melt additionally contains a boron-oxygen and/or a boron-fluorine compound.

Title: Tall wooden agricultural silo vegetable juice drainage - involves full height vertical perforated run-off ducts on walling inside
Inventor: HORNDASCH HERMANN
IPC: E04H7/32
Filed: 1980-05-28
Abstract: Drainage extending over the full height is provided for tall silos made of wood, esp. as used for storing vegetable fodder. Fermenting juice is conducted to the silo floor slab by a series of upright runoff ducts on the inside of the walling (12), incorporating holes or slots. The runoff ducts are pref. located on both sides of entry hatches, and/or distributed round the silo periphery. A horizontal, similarly perforated duct, on the floor slab along the inside wall, can convey juice onwards to the outflow shaft in the floor. Upright ones may have tubes of various shapes, or grooves let into the walling. This provides effective runoff facilities over the whole height, and automatically reduces internal pressure arising from juices, while preventing any uncontrolled escape harmful to the environment.

Title: Increasing the throughput of rotary drum redn. furnace - by controlling vol of air injected into furnace, esp. when mfg. sponge iron by reducing iron ore with coal
Inventor: WENZEL WERNER PROF DR ING
IPC: C21B13/08
Filed: 1980-11-08
Abstract: Combustible gases (I) in the furnace charge are burnt by the direction injection, through the furnace wall, of air of combustion or other gases (II) contg. oxygen. Gases (I) are formed by the evapn. or decompsn. of cpds. in the charge, and are burnt inside the latter by gases (II). The position of the injectors for gases (II) and the amt. of such gas (II), are chosen to suit the compsn. of the charge, and esp. to suit the amt. of fine-grained material in the charge. When fine ore is used with a grain size of ca. 80% below 0.5mm, as the furnace charge, the amt. of air or gas (II) is pref. reduced to ca.50% of the stoichiometric amt. required for the combustion of gases (I). When fine iron ore is reduced in a rotary drum furnace, the sponge iron obtd. tends to sinter together to form agglomerates reducing the throughput of the furnace. This undesirable tendency is assessed by a sticking factor(SF), which is the ratio of the average dia. (A) of the sponge agglomerates to the average dia. (E) of the ore grains. The invention produces a marked redn. in this ratio(SF).

Title: Device for producing multi-component plastics
Inventor: TAUBENMANN PETER
IPC: B01F15/04
Filed: 1981-09-12
Abstract: In the production of multi-component plastics, in particular those with solids as additive to at least one of the components, said multi-component plastics are transported with the aid of a piston-cylinder unit consisting of a metering cylinder and a drive cylinder. The variation of the component flow rate in the metering cylinder is brought about by varying the conveying rate of a hydraulic pressure medium which can act on the drive cylinder. To relieve the sealing elements, in particular to relieve the roof-type sleeve seal sealing off the components in the metering cylinder, the space between the sealing elements arranged at a distance from one another is acted on by a sealing liquid which is chemically neutral with respect to the material of the sealing elements. In this manner, penetration of abrasive solid particles into roof-type sleeve seals is prevented and the plastic component and the sealing liquid are always under proportionally the same pressure difference in temporal sequence.
