IPC: C10K1/34
Filed: 1980-06-03
Abstract: In a process for the purificn. of crude gas from the partial oxidn. at 1000-2000 deg. C, the gas is cooled and freed of dust and then passed over a supported catalyst contg. 1-20 wt.%, of the sulphides of Mo, W, Co and/or Ni. Pref. mixed Mo and Co sulphides are supported on Al2O3. The temp. is 70-250 deg. C, pref. 90-200 deg. C; and the pressure is 1-100 bar, pref. 2-60 bar. The space velocity is 3000-30,000 N cu.m. gas per cu.m. of catalyst per h. The catalyst treatment precedes the acid gas wash and occurs before or between the first of any gas compression stages. Used for treating gases from, e.g., the Koppers-Totzek partial oxidn. process, with coals, coke, pitch, tar, etc. as feedstocks. Unlike some prior art, the process removes SO2 as well as NOx. Fouling due to both these is avoided. The catalysts are cheap, widely applicable, and do not deposit carbon.

Inventor: SCHWAB GUENTHER DIPL PHYS DR
IPC: H02P23/18
Filed: 1980-09-11
Abstract: In the method and circuit for adjusting the rotation speed or the frequency of an electric motor (according to the PLL principle), frequencies or reference pulses generated by a frequency generator (2) connected to the input of an AND gate (7), of which the second input is connected to the output of a locking circuit for locking the reference pulses (5), as well as the frequency of the motor or the tachymetric pulses generated by a tachymetric generator (4) driven by the motor and connected, via a pulse forming device (10), to the input of a second AND gate (8), of which the second input is connected to the output of a locking circuit for locking the tachymetric pulses (6), are provided to a phase regulating circuit having a flip-flop RS (1) of which the output controls the electric motor (3) via an amplifier stage (9). The input (S) of this flip-flop RS (1) is connected to the output of the first AND gate (7) while the output of the second AND gate (8) is connected to the input (R) of the flip-flop RS (1). The inputs of the circuit locking the reference pulses (5) are connected on one hand to the frequency generator (2) and on the other hand to the output of the second AND gate (8) as well as to the output of the flip-flop RS (1). The inputs of the circuit locking the tachymetric pulses (6) are connected on one hand to the output of the pulse forming device (10) and on the other hand to the output of the first AND gate (7) as well as to the output of the flip-flop RS (1). Thus, each reference pulse energizes the input (S) of the flip-flop (1) which then provides driving pulses to the electric motor. Each tachymetric pulse energizes the input (R) of the flip-flop RS (1), thereby preventing the driving pulses to reach the electric motor (3).

Title: Vehicle which is capable of travelling on rails
Inventor: MEHREN HERBERT
IPC: B61F9/00
Filed: 1981-02-03
Abstract: In a vehicle (1), in particular public transport vehicle for local traffic, which is capable of travelling on rails and has steerable vehicle wheels (8) and transverse guide rollers (11) arranged on each side of the vehicle (1), the said rollers are attached to the end of a carrying arm (10) in an easily interchangeable fashion with the intermediate connection of an alternating component (13). In order to relieve the carrying arm (10) of destructive forces resulting from a possible collision of a transverse guide roller (11) with a mobile obstacle or the like, a predetermined break point (15) is attached to the changeable component (13). The predetermined break force is approximately 10-25% of the empty weight of the vehicle. The flying off of a broken-off transverse guide roller (11) is prevented by interception means located parallel to the predetermined break point (15), in particular by a helical tension spring (22). A rip wire loop (25) which is laid over the predetermined break point also permits even slight triggering of the predetermined break point (15) to be indicated. <IMAGE>

Title: "Process for preparing a pn-junction in a semiconductor material of group II-VI"
Inventor: NISHIZAWA JUN-ICHI
IPC: H01L21/368
Filed: 1981-06-11
Abstract: A process for preparing a pn-junction in a semiconductor material of group II-VI is described which contains Zn. To this end, an n-type zone is formed either locally or in the entire semiconductor crystal, the crystal being grown from the liquid phase employing the temperature difference method. The crystal is then subjected to a thermal secondary treatment in a Zn melted solution or a Zn atmosphere, in order to obtain an n-type zone. The crystal growth to obtain the p-type zone is effected while maintaining a controlled vapour pressure of the group VI element. Owing to the individual measures being coordinated, a pn-junction of increased stability is obtained.
