Title: Read-write memory content protection for telephone systems - has gating circuit to ensure read-write instruction is correct before data is changed
Inventor: PAULUS FRANZ
IPC: G11C11/414
Filed: 1977-07-25
Abstract: The control of read-write memories used in telephone communication systems is effected in such a way to avoid the loss of stored information due to errors in addressing. Typically a number of memories (B1, B2, B3, B4) are operated from a central control circuit (ST) that insures read-write commands (RW), handles data and receives outputs (A, D) and provides an identifying address for the memories. If one memory (B3) receives a read write (RW) instruction, the control unit generates a separate signal that is latched (K1) and both signals are combined in an AND gate (G1). Only if both signals are present is the write process allowed.

Patent DE-2835533-A1 (DE)
Inventor: SCHEUNEMAN JAMES HERMAN
IPC: G06F12/16
Filed: 1978-08-14
Abstract: A method of and an apparatus for obtaining double bit error correction capabilities in a large scale integrated (LSI) semiconductor memory system using only single bit error correction, double bit error detection (SEC, DED) logic are disclosed. The method is based upon the statistical assumption that in a large scale integrated semiconductor memory, substantially all errors in the data bits that make up a data word are initially a single bit error and that increasing multiple, i.e., double, triple, etc., bit errors occur in a direct increasing ratio of the use or selection of the data word. In the present invention, all data words are priorly tested to be error free. Subsequent detection of single bit errors results in the correction of the single bit error and the storage of the single bit error correcting syndrome bits in a syndrome bit memory. Subsequent detection of double bit errors, in the previously single bit error detected and corrected data words, results in the correction, by single bit error correcting syndrome bits, of the previously detected single bit error. This single bit error corrected data word is then again single bit error corrected, i.e., two successive single bit error corrections, to provide a twice corrected double bit error data word.
Patent DE-2842748-A1 (DE)
Title: Prestressed concrete vessel for high temp. gas-cooled reactor - has temp. balancing circuit between different zones without external cooler
Inventor: FILSER ERICH
IPC: G21C11/08
Filed: 1978-09-30
Abstract: A pressure vessel contains a number of metal-lined vaults housing a gas-cooled, high-temp. reactor and other separate plant components. Inside the body of the pressure vessel at a distance from the surface of the liner a heat transport system consisting of a number of cooling tubes is arranged in a circuit of such a form that heat is transported from hot zones to cooler zones of the concrete vessel without the circuit passing through any external heat exchanger for cooling the heat transport fluid. The circulation of the fluid within the tubes may either be by natural convertion or by forced circulation with pumps. Temp. balancing is produced throughout the interior of the pressure vessel, thus reducing temp. difference and consequent thermal stresses. A highly reliable system with no external heat exchanger is used.

Title: Side and face milling cutter - has cutting edges with positive rake on both faces
Inventor: HEINE KARLHEINZ ING GRAD
IPC: B23C5/10
Filed: 1978-11-30
Abstract: The usual type of side and face milling cutter has spiral flutes which produce cutting edges with positive rake on one face and negative rake on the opposite face. The cutting edges with negative rake are less efficient and need to be re-ground more frequently. This problem is overcome by making the cutter in three parts (2) (3) (4) which fit together along stepped joint faces (Sp1) (Sp2). The end section (2) has two types of cutting edges, one set which form a continuation of the flutes (4) of the main cutter and a second set which form spirals of the opposite hand so that these cutting edges have positive rake.

Title: Microphone inset for telephone handset - has grooves on inside of casing to flatten frequency response
Inventor: HOFMANN HERBERT
IPC: H04R1/22
Filed: 1978-12-02
Abstract: The electroacoustic transducer has its frequency response flattened out by an appropriate design of the coupling between the inside of the casing (1) and the outside (6) of the part (3) holding the component. This coupling is such that either the inside or outside has axial grooves (rifling) and the other side is smooth. The grooves are pref. on the inside of the casing whilst the outside (6) of the part is smooth. The advantage lies in simplicity. Use is made of components that are already present.

Title: Electrochemical machining of metals - in appts. which is also used for inexpensive detoxication of neutral or basic electrolytes or their waste solns.
Inventor: RUPPRICH SIEGFRIED DIPL ING
IPC: C25F7/02
Filed: 1979-02-10
Abstract: After the machining, the electrolyte or soln. contains heavy metal ions, esp. Cr(VI); the machined workpiece is removed, and Fe(II) ions are generated in the machining appts. for redn. of ions in the electrolyte. The pref. reducing agents are Fe(OH)2 and Fe3O4 obtd. by electrochemical dissoln. of an unalloyed steel electrode used instead of the workpiece in a soln. of alkali-chlorides and/or -nitrates; during redn., a protective gas, esp. CO2, N2 or Ar, is pref. used to reduce the effect of O2 in the ambient air on the Fe(II) ions. The consumable steel electrode may be a workpiece with a higher iron content than a high alloy workpiece previously machined in the electrolyte. A substantial saving in detoxication costs can be achieved.
Patent DE-2920735-A1 (DE)
Inventor: DORFMEISTER KARL DIPL ING
IPC: H02H7/08
Filed: 1979-05-22
Abstract: The level of stability of a synchronous machine can be assessed, inter alia, from the magnitude of the rotor angle, load angle or partial-load angle. The disadvantage of the measurement methods which have already been disclosed is that the said angles can neither be unambiguously defined nor measured during power supply short-circuits. The generator (1) supplies the transformer (19) via the power circuit breaker (17), which transformer (19), for its part, is connected to the power supply via the power circuit breaker (18). The machine parameters, which are detected by the trigger circuit (6), and the power supply parameters, which are detected via the measurement transformer (3) and the trigger circuit (2) and with the aid of a downstream-connected averaging device (4), are entered into the comparator stage (5) for steady-state values. The DC voltage pulses which are produced by rectifying one half-cycle are counted in binary form. After a specific time interval, the measurement result is detected by the averaging device (4) and is supplied to the comparator stage (5). It is thus possible to decide during the period of the short-circuit itself whether the angle, which will be reset after the short-circuit has been remedied, is still within a value which is acceptable to the machine or whether this value has already been exceeded. <IMAGE>
