Gábor Kornél Tolnai

In 1932, he met his Swedish wife at a party in the "Winter garden" (Vinterträdgården) at Grand Hôtel Royal in Stockholm, when the Swedish-Hungarian society had a jubilee.

The Swedish artist David Wallin had just sold a painting, Mother and Child,[2] to the Museum of Fine Arts in Budapest (Hungarian: Szépművészeti Múzeum), and David Wallin was invited to Grand Hotel Royal (Grand Hôtel Royal with the Winter garden) and he took his 22-year-old daughter Bianca with him.

[citation needed] Gábor Kornél Tolnai entered the German-speaking Lutheran Fasori Gimnázium in Budapest for eight years in 1912 through 1920.

In the autumn of 1927 Tolnai returned to Budapest and became an employee of the Group Linum-Taussig in Budapest as a technical superior and supervisor of the company's industrial spinning machines for spinning textiles manufacturing in the process (Manufacturing process management, MPM) of creating yarn from various raw fibre materials.

For the company Linum-Taussig Kornél Tolnai also worked as a supervisor in the city of Győr (German: Raab) at their spinning machine factory there.

The company in Győr had mechanical flax- and hemp weaving for surface treatment, finishing and impregnation, fabrics of jute, production of bags and tents transportation.

The plant had a wide product range of tablecloths, towels, pressings, tarpaulin sheets, and canvas cloths made up of technical textiles.

Linum is a genus of approximately 200 species in the flowering plant family Linaceae, native to temperate and subtropical regions of the world.

A year later, in the autumn of 1928, he established himself as self-employed in Budapest with a precision-tool workshop, whose activity was based on three of his own inventions, which he had patented.

Over time, the company became, under his sons direction, only a sales agency for a variety of manufacturers of machines and accessories for the textile industry.

The procedure for granting patents, requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements.

A patent is a set of exclusive rights granted by a sovereign state to an inventor or their assignee for a limited period of time, in exchange for the public disclosure of the invention.

During the 1930s Kornél Tolnai sometimes had his meetings with the L. M. Ericsson board of directors in the South Kings' Tower in Kungsgatan 33, as the company had until 1940 its representative office[7] here.

The plant in Budapest continued to report a profit during the 1920s, since the Hungarian PTT placed half of its orders for telephone equipment with Ericsson.

In the Skandinavisk Tidskrift för Textilindustri (Scandinavian Journal of Textile Industry), N:o 7-8, 1931, which was printed at AB Borås Tidningstryckeri in Swedish, there was an article about Kornél Tolnai's invention with text and pictures.

The title of the article was A valuable tool for rationalization of industrial operation, Business professionals, investors and manufacturers insist on an economic production.

(In Swedish: Ett värdefullt hjälpmedel vid rationalisering av industriell drift, Affärslivet, aktieägare och fabrikanter yrka på en ekonomisk produktion.)

The lecture had the same information as was printed in the Hungarian trade technical journal "Magyar Textiltechnologusok Lapja", May 25, 1934 "TEXTIL-IPAR", Budapest.

In 1934 it was reorganized again as Palatine Joseph University of Technology and Economics and it played a dominant role in the interwar industrialization process, together with engineering and economist training in Hungary.

In the mid-1930s the foundation for the company's most famous product was laid, the Bofors 40 mm automatic cannon, which during World War II were produced in different countries in 10,000 numbers of copies.

AB Bofors was a Swedish industrial company and arms manufacturers headquartered in the town of Karlskoga in Örebro County in Värmland.

Tolnai had built his invention Reportoskop and he demonstrated it during the Olympic Games in Berlin on August 1–16, it should he used to follow an athlete (sportsman), for instance a runner on the running track.

Arenco was incorporated in Svenska Tändsticks AB (STAB) in 1917 with a diversified product range covering, apart from match machinery, also packaging and fish processing machines.

During the years 1950–1977 Kornél Tolnai ran his own company together with a few employees, at first on Främlingsvägen 47 in Hägersten, and then on Hälsingegatan 6 in Vasastan, both in Stockholm.

Analog (or analogue) recording (Greek, ana = "according to" and logos = "relationship") is a technique used to store signals of audio or video information for later playback.

Perfected by Thomas Edison in 1878, the phonograph was a device with a cylinder covered with an impressionable material such as tin foil, lead, or wax on which a stylus etched grooves.

Engineers at AEG, working with the chemical giant IG Farben, created the world's first practical magnetic tape sound recorder, the 'K1', which was first demonstrated in 1935.

Before 1963, when Philips introduced the Compact audio cassette, almost all tape recording had used the reel-to-reel (also called "open reel") format.

The reel-to-reel format was used in the very earliest magnetic tape sound recorders, including the pioneering German Magnetophon machines of the 1930s.

The reel-to-reel audio tape recorder and the cafe machine was a kind of jukebox (disc changer), and for music reproduction at home and at school as well as for teaching purposes, a so-called "Study Master" or tape recorder called Tolnai Study Master for language teaching in schools.
