Patent DE-2917048-A1 (DE)
Title: Covered refuse compositing building - divided into horizontal cells with turnover devices
IPC: C05F17/00
Filed: 1979-04-27
Abstract: Refuse and/or sewage sludge is converted into compost in a covered building which is subdivided into several floors, each split by longitudinal partitions into cells. At one end, the raw material is charged into the cells by vertical screw conveyors and fresh air is admitted through blowers. Paddle wheels run along racks on the walls to turn the material over and take it to the chutes at the other end. Exhausters remove the waste air at that end and press it through an earth filter which covers the flat roof of the building. Such a covered building speeds up the digestion period for the compost and can be a very light structure because of its subdivision into cells.

Title: Telephone exchange call tone verifying circuit - has buffer register storing signal from loop current indicators
Inventor: ROTH PETER ING GRAD
IPC: H04M19/02
Filed: 1979-06-23
Abstract: The circuit detects a loop current at the subscriber appts. via indicators (I) inserted in the subscriber circuit. The signal (S) from the indicators (I) is stored via a buffer register (SR) during emission of the call current, the buffer register (SR) controlled by a clock signal coinciding with the zero crossing points of the AC call current supplied to the subscriber line. After several such zero crossing points a signal (SA) appears at the output of the buffer register (SR), which is combined with the direct signal (S) from the indicators (I) via a logic gate. The control clock signal (T) for the buffer register (SR) is pref. obtained via two anti-parallel optical couplers associated with a resistor.

Easier demoulding and better surface finish of components than from usual mineral oil types are obtd. The emulsions than from usual mineral oil types are obtd. The emulsions cause no pollation, e.g. of ground water, or skin complaints. Costs of after-treatment of components and repairs to moulds are reduced. Fire and explosion hazards are eliminated waiting times during pre-fabrication or on site are reduced. Multiple mouldings may be produced from a single coating, and no oily residue is left on the concrete to interfere with subsequent treatment.

Title: Heat recovery from evapn. vapours in sugar prodn. - using heat in vapours to provide heat for evaporative crystallisation stage thus reducing overall energy requirement
Inventor: SCHROETER EKKARD DIPL ING
IPC: C13B25/00
Filed: 1979-08-29
Abstract: Heat from the evaporative stages in sugar prodn. is recovered in the evaporative crystallisation stage by first cooling the inlet feed of concentrated syrup. Cooled feed is fed into the recirculating stream of liquor round the crystalliser. Recycle stream passes through a heat exchanger in which it is heated by the vapour from the final evapn.stage. Pressure reducer is provided between the exchanger and the crystalliser so that vapour can flash off. Pressure reducer can be a non-return valve. The process is for use in sugar refineries. It extends the process in DE 2729192 to evaporative crystallisation of thick syrup.

Title: Electronic component for integrated or thick-film circuits - has conducting sub-regions of specified areas joined by conducting paths
Inventor: KUERZINGER WERNER DIPL PHYS DR
IPC: H05K1/16
Filed: 1979-09-11
Abstract: The component has a flat layer of electrically conducting material divided into electrically-connected sub-regions. The sub-regions (4-7) have different areas. These areas are integral multiples of one another, pref. having ratios that are integral powers of two. The Sub-regions form the electrodes of capacitors and are parallel to one another and connected by a path (11) of electrically conducting material and form a comb-like capacitor electrode. The sub-regions near the path blend into narrower connecting bridges (8-10) that join the path to the sub-regions. The sub-regions may form a parallel circuit of resistors or the electrodes of a semiconductor. The advantage lies in compactness, whilst at the same time allowing the electrical properties of the circuit to be readily adjusted.

Title: Price calculating microprocessor balance data safety circuit - transfers data to non-volatile memory when power failure detected
Inventor: SEIBT ARTUR DR ING
IPC: G06Q30/00
Filed: 1980-09-11
Abstract: The arrangement which records information about goods, e.g. price and wt., comprises a price calculating balance with a printer producing receipts. It contains a microprocessor with a read-only program memory, volatile and non-volatile memories, and several peripherals such as a weighing cell and data input.
