Title: Apparatus for feeding a data drain with data words while using a series-parallel converter
IPC: H04L1/14
Filed: 1980-11-14
Abstract: 1. A device for the recognition of transmission errors in data transmission from a data source to a data sink, with serial clock-pulse-controlled transmission of variable data words of predetermined length and with likewise clock-pulse-controlled parallel data processing in the source and in the sink, and with retransmission of a fixed check word and of the transmitted data word to the source for comparison with a characteristic of the sink and with the transmitted data word, where in the event of identity between these two the data word which has been transmitted to the data sink is to be released by the data source, characterized in that the parallel-inputs of a parallel/series converter (PS) arranged at the location of the data sink can be supplied wit the transmitted data word (via SP) and with the fixed check word (via SS) in such manner that on the read-out of the converter for the retransmission of data word and check word the check word passes through those storage positions of the converter (PS) which have previously been occupied by the data word immediately following the data word and that at the location of the data source there is provided a fail-safe comparator (V) which can be actuated (via U) following a number of clock pulses after the series/parallel conversion (in SP), which number corresponds to the summed number of digits of a data word and a check word.
Patent EP-0031180-A3 (EP)
IPC: H01L29/207
Filed: 1980-12-08
Abstract: A method of growing III-V alloy layers by a molecular 
beam epitaxy process. Difficulties have been experienced 
when growing doped III-V alloy layers by conventional 
molecular beam epitaxy processes due to the introduction of 
electron or hole traps which impair the electrical and optical 
properties of the alloy. Such III-V alloy layers are used in 
making microwave and opto-electronic semiconductor 
devices such as field effect transistors and laser diodes.  
     In the present invention, an epitaxial layer (48) of a doped 
III-V alloy is grown on a semiconductor substrate (1) by plac­
ing the substrate (1) in a vacuum chamber (3), reducing the 
pressure in the vacuum chamber (3) to below atmospheric 
pressure, maintaining the substrate (1) at a temperature inthe 
range from 300 to 500°C, and directing a plurality of molecular 
beams containing the constituent elements of the doped III-V 
alloy and a molecular beam of lead onto the heated substrate 
(1). The magnitude of the lead flux is sufficient to form and 
maintain a presence of from 5 to 20% of a monolayer of lead 
on the growth surface..

IPC: B02B3/00

Abstract: Process to achieve an industrial separation of the cortical 
part from inner part of the rhizomes of irises, or of rhizomes or 
roots of officinal plants having similar physical characteris­
tics, that separation having been up-to-now effected manually 
and done in order to eliminate odours, tastes and other prop­
erties that degrade the materials extracted from the said rhi­
zomes or roots, said materials being utilized in the penfumery, 
pharmaceutical and alimentary industries.  
     With this method a grinding phase must come before that 
of decortication and the ground components are treated in 
one of two ways. In one solution the two components, when 
mixed in a proper liquid, get separated from one another 
according to the difference between their specific gravities. In 
a second solution the process is characterized by the fact that 
the specific gravities of the two components tend to diminish 
as the seasoning of the rhizomes, or roots, goes on, reaching 
values that are lower than those of water, or of a proper 
solution, and when these components are ground and mixed 
with said liquids they return to their original values at different 
rates.

Title: Process and apparatus for detection of electrically conducting material
IPC: G01R33/12
Filed: 1982-09-27
Abstract: When an electrically conducting material is subjected to an alternating magnetic field local changes in the magnetic field adjacent to the conducting material are detected by a detector comprising a magnetoresistor or Hall crystal which generate an electrical signal when subjected to the magnetic field. The process and apparatus can be used to identify, classify and locate electrically conducting material.The detectors can be of the order of a few millimeters in size and so can be used to detect local changes in the magnetic field over correspondingly small areas of the material.The invention is particularly useful in identifying coins used in coin operated machines.

Title: Microphone
IPC: H04R19/04
Filed: 1983-05-26
Abstract: An electroacoustic transducer system comprises a microphone working into a low-frequency amplifier for the energization of an a-c load such as, for example, a loudspeaker or a volume indicator at a control panel. Biasing voltage for the microphone and operating current for the amplifier are derived from a d-c source, via a phantom circuit including the output leads of the amplifier and through a coupler in cascade with a chopper; the latter includes a transistor conducting intermittently under the control of an adjustable pulse generator whose pulse width is varied by negative feedback from the integrated chopper output. An output transformer with a primary in series with the transistor has several secondaries each connected across a storage capacitor through a diode for the generation of a relatively high biasing voltage for the microphone, a relatively low driving voltage for the amplifier and, possibly, a further voltage used to vary the directional pattern of the microphone. To facilitate the establishment of different voltage levels, the development of the lower voltage is delayed-by the combination of a choke with a Zener diode, or by a thyristor-until the higher voltage has been reached by a transient occurring at the beginning of each cutoff phase.

material. Accordingly, the less-or untensioned intermediate
