Patent DE-2340996-A1 (DE)
Title: Electronic arm strength game with electronic scoring - has keys for elbows and hands of competitors, also "disqualifications" indication
Inventor: SCHOBER EBERHARD
IPC: A61B5/22
Filed: 1973-08-14
Abstract: Appts. for comparison of arm strength has two keys on which the elbows rest, two keys on which the hand of the competitor is pressed respectively, and two keys to indicate readiness. Six lamps show the state of the game, for 'winner', 'loser', and 'disqualified'. A summer is controlled by a timer relay and shows the end of the game. The keys and lamps are built into a frame, which may also have legs and a coin slot mechanism. The lamps are electrically arranged, and the course of the game is monitored, so that no fraud is possible, and an attempt at it immediately lights the 'loser' and 'disqualified' lamps. Each circuit state, connected to the short-period summer, goes via a corresponding circuit into a 'hold' state, and continues until the next game starts. A further circuit ensures that in normal play the 'loser' is not also shown as 'disqualified'. A 'cancel' key can be installed instead of the coin automatic system, to interrupt the current and release the 'held' states.

Title: Desulphurisation of coal at high temp. - with hydrogen recycle for desulphurisn. and heating
Inventor: SCHROEDER WILBURN C
IPC: C01B17/16
Filed: 1974-12-04
Abstract: Coal is desulphurised by (a) contacting the coal at 593-982 degrees C (pref. 816-982 degrees C) with recycled hot H2-contg. gas in the desulphurisation zone of a closed system, to convert the S cpds. in the coal to H2S; (b) separating the desulphurised coal with the gas mixt. formed; (c) separating the H2S from the gas mixt; (d) recycling part of the purified gas for further contact with the coal; and (e) burning part of the purified recycle gas to obtain sufficient heat to heat the coal to the required temp. The process is based on the fact that the H2 liberated when coal is heated is more than enough to react with the S-contg. impurities; thus a large proportion of the H2 liberated can be used for heating and only O2 need be supplied (steam is not necessary).

Title: Wood chip digester process - uses continuous feed giving a controlled steeping consistency to give effective penetration of wood
IPC: D21C1/00
Filed: 1975-04-02
Abstract: The decomposing process for wood chips, in a digester for the prepn. of a stock suspension for conversion into paper, uses a continuous feed of small chips together with a steeping soln. contg. the required decomposing chemicals, with a controlled feed rate so that in the steeping zone the consistency is held below 10% so that the ratio of soln. to chips is not more than 9:1. The mixt. is passed into a processing zone where it is stirred vigorously with the wood particles having an equal dwell time at a temp. and pressure where they are softened without being boiled. On removal, the surplus fluid is recirculated to the digester and the steeped chips passed for boiling. The process ensures that the wood particles are effectively and equally steeped, with a lower rejection rate than established processes.
