Title: Pyrolysis of carbonaceous fuels in cyclone separator - with solid heat carrier, giving higher yields of middle distillate
Inventor: CHOI CHARLES K
IPC: C10J3/54
Filed: 1977-06-24
Abstract: Pyrolysis of carbonaceous materials e.g. coal, tar sands, shale, refinery residues, etc. comprises contact withheated solid particles, in which a stream of the fuel is passed tangentially into a cyclone separator and a stream of heated particles in an inert carrier gas is introduced at an angle, in amt. sufficient to heat the fule to 315 degrees C min. The mixt. of carrier gas and pyrolytic vapours is simultaneously separated from the mixt. of heat carrier and carbon-contg. residue by centrifugal forces in the separator, produced at least partly by the initial flow velocities of the streams. Solid and low-value fuels are converted to gaseous and liquid prods. Pyrolysis time is very short (0.1-3, pref. up to 1 s.) giving increased yields of liquid hydrocarbons in the C5 to 510 degrees C b.pt. range, from which petrol, diesel fuel, heating oul, etc. are obtained, compared with pyrolysis in usual tubular furnaces.

Title: HF communications system for pit railways - maintains contact through pair of trackside cables connected at one end through amplifier
Inventor: DUNKER GERHARD DIPL ING
IPC: H04B5/00
Filed: 1977-07-01
Abstract: A system is used for the transmission of HF signals between a transmitter and a receiver, both of which can move along a predetermined track which may be curved, and may take the form for example of a railway track passing through a tunnel. Along the track a pair of parallel radiating cables is laid, which are joined at one end through an amplifier. The relative positions of the cablees may be such that their coupling attenuation is greater than the gain of the amplifier. The free ends of the cables may be terminated in their characteristic impedances to prevent reflections. The system ensures that the two moving stations remain in contact through the cables although they may be out of direct line-of-sight contact. It is especially applicable to pairs of locomotives in undergroun mine workings.

Patent DE-2739425-A1 (DE)
Title: Gas oxygen content determination - involves creating electrical discharge and measuring arc voltage
Inventor: ABELE ROLF
IPC: G01R13/36
Filed: 1977-09-01
Abstract: Contacts in a test device are closed and the voltage drop across them is effectively zero. On opening the contacts a series inductance causes the voltage across them to rise rapidly, initiating the striking of a discharge in the surrounding gas. The voltage across the contacts then falls to a relatively stable value (UB), the burning voltage, which is then measured. It has been found that the oxygen content of the gas surrounding the contacts controls the magnitude of the stable burning voltage and thus, by reference to a calibration curve, the oxygen content can be ascertained.
