Title: Keyboard electronic musical instrument circuitry - uses keyboard reference oscillator into phase comparator VCO feedback circuit for synthesis
Inventor: MAYER-LINDENBERG FRITZ DR
IPC: G10H5/00
Filed: 1980-05-10
Abstract: The instrument's keyboard is coupled to a reference oscillator so that a square wave according to the notes played is presented at one input of a phase comparator. The second input is the control loop from the output of the v.c.o. The output of the phase comparator is a voltage which increases or decreases according to frequency deviation on the input and which is fed to an integrator before being applied to the control input of the v.c.o. The latter alters its frequency until it agrees with the phase comparator input frequency and the phase comparator output voltage has disappeared. Frequency division may also be used to provide a 2:1 or 4:1 octave modification of the oscillator frequencies.

Patent DE-3046171-A1 (DE)
Inventor: SCHOEN CHRISTIAN O
IPC: C04B41/45
Filed: 1980-12-06
Abstract: Carbon electrodes are impregnated with pitch during transport in mobile vessels which first travel to a heating station where the electrodes are heated in several stages by gases which are hotter from stage to stage. The vessels next travels to a station where the sealed vessels are connected with a suction pump to evacuate the fluid from their interiors and from the pores of the electrodes therein and where the vessels are substantially filled with pitch which is caused to penetrate into the empty pores. The vessels then travel to a station where the contents of the vessels are pressurized to ensure complete permeation of electrodes with pitch. The vessels subsequently travel an optional station where the electrodes in the vessels are baked to convert the pitch into coke, and to one or more cooling stations where the electrodes are heated by air, water and/or nitrogen. Fumes which develop during heating, evacuation of fluid from the pores, baking and cooling are filtered to avoid contamination of the surrounding area.

Patent DE-3111415-A1 (DE)
Title: Measuring-gas cooling device
Inventor: GEERKENS FRIEDHELM
IPC: G01N33/00
Filed: 1981-03-24
Abstract: A measuring-gas cooling device is described which consists of a cooling unit and a refrigeration chamber which is thermally insulated from the outside and contains refrigerant which is generated by the cooling unit and flows around a gas heat exchanger, arranged in the refrigeration chamber, with a connected condensate separator. The coolant pressure in the refrigeration chamber is held at a fixed value by means of a control device and, in this way, the measuring gas passed through the gas heat exchanger is not only provided with a fixed temperature, but the moisture content is also brought to a defined value. Because the coolant of defined temperature or defined pressure flows directly around the gas heat exchanger for the measuring gas, the temperature and the moisture content of the measuring gas issuing from the measuring-gas cooling device can be maintained particularly accurately and, especially, the temperature can approach very closely the freezing-out temperature of entrained moisture.

Title: Iron with the possibility of use in confined or not very accessible places
Inventor: WILFERT CHARLOTTE
IPC: D06F75/38
Filed: 1981-04-11
Abstract: The subject of the invention is an iron with the extended possibility of use in confined or not very accessible places. For this purpose, the iron is combined with a small iron (mini-iron), in such a way that the small iron can be retracted into the iron and can be pushed out of the latter into a position of use. At the same time, the arrangement is such that the small iron does not disturb the work of the iron when the small iron is not required. The extension of the small iron takes place to such a distance and into such a position relative to the iron that the view of the small iron and its working parts is not blocked when the small iron is required for carrying out work.

Title: Duplex transceiver device
Inventor: KLOEBER PETER DIPL ING
IPC: H04B1/50
Filed: 1981-07-22
Abstract: The invention relates to a duplex transceiver device for a digitally modulated radio system with only one oscillator for the transmission and reception branches. A device of this type for information transmission between mobile and stationary transceiver stations is intended to be extended so that a full-duplex speech channel independent of the data transmission using the FSK method can also be transmitted. For this purpose, the invention provides a third and fourth frequency condition (f3, f4) of the mobile transceiver station in addition to the two discrete modulation frequencies (f1, f2) of the FSK modulation. The position of the oscillator frequencies (f1', f2' or f1, f2, f3, f4) of the mobile and stationary transceiver stations is selected in such a way that, in the reception branch of the stationary transceiver station, two IF combination frequencies (fZF1, fZF2) are produced from the first two frequency conditions (f1, f2) as carriers of the received digital FSK information. These are fed via an IF filter (7) to an FSK demodulator (8) to which a digital network (9) is connected downstream. <IMAGE>

Title: Method for speaker-independent recognition of spoken words in telecommunications systems
Inventor: LIEGL WERNER DIPL ING
IPC: G10L15/06
Filed: 1981-07-24
Abstract: The invention relates to a method for speaker-independent recognition of individual words from a provided word set in telecommunications systems with the aid of an electronic speech recognition system which essentially comprises a synthesis system which reproduces the words, a processing unit which splits spoken words up into parameters and a reference pattern memory containing reference patterns allocated to the words, a specific number of the individual words being spoken by a plurality of persons in the so-called learning phase. The intended object of the invention is to keep the recognition rate of the recognition device as high as possible despite the largest possible number of different speaking persons. The object is achieved in that every word which is spoken by a trainee and recognised is replicated by the synthesis system and reproduced in the learning phase to form the reference pattern. This allows the trainee to get used to the "machine language" and to adapt his mode of speech to it, thereby enabling more frequent recognition of the words by the recognition system.
