Patent DE-2738912-A1 (DE)
Title: Heat energy transportation system - splits, recombines methane; reduces mixt. temp. and pressure before entry into transport line
Inventor: BOLTENDAHL UDO DR ING
IPC: F01K25/06
Filed: 1977-08-29
Abstract: A heat energy transportation system involves a closed gas flow cycle with a source locality where energy is added by splitting methane. The resulting mixt. is transported to the sink locality where catalytic re-combination releases energy again, and the cycle completed. The high temp. (about 825 degrees C) and pressure (about 45 bar) mixture first passes through a gas-turbo generator expanding to 12 bar and about 605 degrees C. It then goes through two heat exchangers - one for the returning methane, the other a reheater in the associated steam-turbo generator system - before entering the transport line.

Title: Hydrocarbon conversion, esp. gasoline reforming - with catalyst contg. cobalt, tin, platinum gp. metal and halogen, which has high activity and is resistant to deactivation
Inventor: POLLITER ERNEST LEO
IPC: B01J23/89
Filed: 1977-09-05
Abstract: Hydrocarbons are converted on an acidic catalyst consisting of (a) a porous carrier contg. (b) 0.01-2 wt.% Pt. gp. metal (0.05-1%), (c) 0.1-5 (0.5-2)% Co, (d) 0.01-5 (0.05-2)% Sn, and (e) 0.1-3.5 (0.5-1.5)% halogen. The Pt. gp. metal, catalytically available Co, and Sn are uniformly distributed through the carrier. The average crystallite size of the Co and Sn is 100 angstroms. the Pt. gp. metal is present as metal, the Sn is present in an oxidn. state above that of the metal, and the Co is present as metal and/or in state which is reducible to the metal under the conversion conditions. The pref. use is the reforming of a gasoline fraction to give a high octane reformate. Other conversions include (hydro)cracking, hydrogenolysis, (hydro)isomerisation, (de)hydrogenation, desulphurisation, cyclisation, polymerisation, alkylation, and de- and trans-alkylation.

Title: Cylinder lock flat key with grooves - has guide and blocking grooves of different profiles for master keys
Inventor: KRIESTEN KARL
IPC: E05B19/06
Filed: 1977-09-08
Abstract: The cylindrical lock flat key has grooves ensuring that any master or subordinates keys of the system have geometrically different grooves. The cross-section profile of the blocking groove can vary from triangular shape to parabolic and finally into a rectangular cross-section. The key has near its back edge, a guide groove (3) for guiding rib of the key channel of the cylinder core. A triangular cross-section blocking groove (10) is arranged on the opposite side of the key. This groove cross-section can vary for producing a master key which can, e.g. deal with a parabolic and triangular rib in the lock.

Title: Metal phthalocyanine catalysts prodn. - by sublimation and conversion to adduct with nitric oxide or oxygen, used for nitric oxide removal
Inventor: STEINBACH FRIEDRICH PROF DR RE
IPC: B01J31/18
Filed: 1977-09-24
Abstract: Prodn. of metal phthalocyanines (MPc) with high catalytic activity is effected by converting technical MPc into very pure form by double sublimation (typically 10-5 torr inert gas, 400 degrees C) and then into MPc adducts or MPc oxyadducts, with much higher activity than the purified MPc, by treatment with NO or O2 at over 250 degrees C; or by conversion to MPc oxyadducts by sublimation in the presence of O2 at partial pressures up to 10-2 at 400 degrees C. These catalysts are specified for use in the redn. esp. hydrogenation or decompsn. of NO, (mainly) to N2 (and some NH3). They are selective, retain their activity well and contain much less metal than highly pure metal oxides.

Patent DE-2753960-A1 (DE)
Inventor: REIN JUN KARLHEINZ
IPC: F02B77/13
Filed: 1977-12-03
Abstract: In order to delivery heating oil to end users, the tanker vehicles have feed pumps. The feed pumps (7) and a pump motor (8) are coupled to one another to form a pump unit on a tanker vehicle and, by means of the same base plate (6), are attached to the floor (1), which is fixed to the vehicle, via sound insulators (5) and elastic holders (2). Motor and pump are accommodated in a housing (3) with a sound-insulating lining (4). The cooling system of the motor is connected via lines (12, 12') to the radiator (16) of the engine of the tanker vehicle and a ventilator (14) with electric motor (15) ensures that air is circulated through the radiator when the engine of the tanker vehicle is switched off. Thus, the engine of the tanker vehicle does not have to operate at a high engine speed which is necessary for the feed pump. Because more power than the pump needs is produced at this engine speed, in addition to the better sound insulation it is also possible to pump more economically. <IMAGE>

Title: Cassette or container coding - has mechanical or magnetic code contents related for mechanical or opto-electronic sensing
Inventor: RIEGER THEO DIPL ING
IPC: G03B7/24
Filed: 1978-12-05
Abstract: The coding method is for film or tape (including video) cassettes or containers so that the contents can be identified and processed correctly in automatic equipment. The method is particularly applicable to film processing and tape dubbing equipments.

The code may be mechanical or magnetic, if mechanical, it is sensed by fingers and microswitches (16, 15) and may be raised or cut in, but facility exists to change the code should the contents be changed. The code may also use opto-electronic, piezoelectric or Hall effect methods. The code would provide such information as the film speed or tape type in the cassette.
