Title: Steam sterilizer - with suction extraction facility and drier for sterilized product
IPC: A61L2/07
Filed: 1971-04-14

Patent DE-2309821-A1 (DE)
Title: Synthesis gas generation - using triple orifice burner designed to prevent heat induced damage
Inventor: MARION CHARLES PARKER
IPC: C01B3/36
Filed: 1973-02-28
Abstract: Synthesis gas is generated by partial oxidn. of normally liq. hydrocarbon streams at 1800-3500 degrees F using a design of burner injection assembly having three separate convergent concentric nozzles. The oil and O2 contg. gas are injected at relative velocities through the two central orifices such that atomisation of the oil takes place downstream from the burner. The third outer annular stream carries the moderator gas (generally steam) which functions to minimise turbulence of the hot prod. synthesis gas. Typical flow rates are liq. hydrocarbon 10-100 ft./sec., O2-contg. gas 110-600 ft./sec., and moderator gas at 55-300 ft./sec.; relative velocity difference of hydrocarbon and oxygen streams is maintained at >=100 ft./sec. The design prevents damage to the burner head caused by erosion and corrosion effects due to the high temps. involved.

Title: Overhead electric pick up for toy trains - uses clamp slider system with hook attachments in support plate
Inventor: ROETHER HELMUT
IPC: A63H19/26
Filed: 1974-01-21
Abstract: Attachment system for the overhead current pick-up on the roof of an electrically driven toy train etc. which moves on rails. There is a clamp slider which makes contact under tension with the current supply rail through hooks in the support plate of the current pick-up rail which are fitted to the roof of the toy vehicle. The clamp slide reaches two hooks of the support plate and extends into a lighting screen wall and into a contact tongue for a current conducting plate. The advantage of the clamping system compared with a screwed pick-up is that it is cheaper to produce and easier to install.
