Title: Receiving and transmitting impulse series interrupted by pauses - using electronic storage without fixed association of memory cells
Inventor: GOSLICH HANS-DIETRICH
IPC: H04M1/27495
Filed: 1973-11-07
Abstract: The invention furnishes an electronic memory storage process for the receipt and transmission of series of impulses, particularly as required in telephone instruments, without using coding or counting arrangements. The process is such that no fixed memory cells are associated with individual impulse series and that one memory cell is used each time for storing an impulse or a pause between impulses. The circuit is cleared only after the first impulse of a new series for storage has been received, so that a telephone connection, if interrupted accidentally, is re-established without re-dialling. After clearance, the matrix connects the store inlet through an inverter with the inlet of the first memory cell, impulses then being stored in sequence by shift register operation.

Title: Smooth-laying trip-preventing concrete path slab - slightly wider to half thickness extent at two abutting edges
Inventor: SCHNEIDER ALFRED
IPC: E01C5/06
Filed: 1974-10-25
Abstract: The concrete slab is designed so that, when it is laid in rows with other slabs, to form a paving for paths, roads or squares, no projecting edges are left which could cause a risk of pedestrians tripping up and falling. The slabs are laid with their edges overlapping by a few cm. The top slab overlaps the bottom slab by the same amount on two sides; the slabs may be square and the top and bottom slabs are displaced along a diagonal. Slabs of this configuration are compactly joined together with no joint gaps, and with a firm holding capacity. The collection of dirt is also effectively hampered. The slabs can also be used for curb paving, in which case the edge of the paving fits the top of the curb.

Title: Compost or sludge treatment in periodically aerated tank - promotes aerobic activity without excessive cooling by constant gas analysis
Inventor: SPOHN EBERHARD DR
IPC: C05F7/00
Filed: 1974-10-29
Abstract: A plant for the aerobic decay and decontamination of composting materials and/or clarified sludge comprises a tank with airtight walls and a grating at an inter. level to support the materials above the floor; the air chamber thus formed above the floor and below the grating has an air extract line leading out of it to an extract blower; a gas analyser measures the oxygen content, or the CO2 content of the air below the grating. When the reading falls below a predetermined, adjustable value, a control unit switches on the blower and opens a valve to draw in fresh air. Pref. the air replacement is carried out with a rapid, powerful extn. giving a complete change of air in a very short time, so that all levels of the bed start agin with a fresh supply. Alternate suction and blowing may be used. Used for treating town waste, other types of waste and sludge. The intermittent air extn. prevents an aerobic activity starting, but does not cool the material excessively by too frequent air changes. All levels of material decay at the same rate.

In this way the backfilled concrete lies flat and fully on the shuttering, without the possibility of sharp stones etc. penetrating and upsetting the bond.
Patent DE-2501295-A1 (DE)
Title: Transmitter limiter circuit modulating signal - has chain of alternate LC allpass filters and limiters to reduce edge time integrals
Inventor: LEIFER ALFRED DIPL ING
IPC: H03G11/00
Filed: 1975-01-15
Abstract: The limiter circuit for a transmitter modulating signal oscillations reduces the time integral of signal half-waves in the region of the leading and/or trailing edges. All pass filter circuits increasingly delay the signal as the frequency increases. The all pass filter circuits are separated by limiters so that an alternating chain is formed. Each all pass filter consists of a T-network with series inductance and earthed capacitance. Each limiter consists of a four-diode bridge, with one diagonal coupled between the supply terminals and the other diagonal forming the input and output terminals. The advantage lies in reducing unwanted consequences of the delay.
