Title: Thermostatic idling regulator in fuel injected I.C. engine - raises air:fuel ratio as engine temperature rises
Inventor: SEILER GUENTER
IPC: F02D1/06
Filed: 1975-09-05
Abstract: I.C. engine thermostatic idling speed regulator for engine having fuel injection, raises air fuel ratio with increasing engine temperature-The regulator is a valve (9) in a by-pass duct (5) through which air enters the induction passage of the engine independently of the setting of an inlet throttle (4). The engine has an injection pump (15) whose stroke is regulated (14) by the air pressure in the induction passage. The valve is controlled by a sensor (7) of engine temperature such that the by-pass flow increased as the temperature rises. The resulting fall of induction pressure reduces the stroke of the injection pump and thus the quantity of fuel delivered to the engine.

Title: Tube cracking furnace in pod of concrete vessel - has easily dismantled feed and discharge headers for process gas
Inventor: BARCHEWITZ EKKEHARD DIPL ING
IPC: C01B3/38
Filed: 1976-04-06
Abstract: Tube cracking furnace comprises a large number of tubes suspended from a support plate mounted on a liner in a pod of prestressed concrete reactor pressure vessel. The gas from the high temp. reactor supplies heat to the furnace and (downstream of this) to a steam generator. The space above the support plate is sealed by this plate from the space below it, contg. the active part of the furnace. Each cracking tube contains a return tube for the cracked gas. The space above the support plate is subdivided by a horizontal, flat tube plate into upper and lower cylindrical chambers, bounded by a cylindrical wall inside the pod and with a top cover plate for the upper chamber. The return tubes from the cracking tubes terminate in the tube plate and discharge cracked gas into the upper chamber, which thus acts as collecting header for this gas. Two coaxial gas ducts penetrate the cylindrical wall; the inner duct conducts gas out of the header chamber, while the outer duct supplies charge gas into the lower chamber, which thus constitutes the feed header for gas, supplying the cracking tubes. Used for producing hydrogen by catalytic cracking of a CH4/H2O mixt. The plant is simple and compact, and can be easily repaired and replaced. Changing of catalyst is simple.

Title: Marking and sorting pressed workpieces e.g. fire bricks - measuring deviation of dimensions from nominal to generate signal controlling amount of material fed in
Inventor: FRANZ GUENTHER ING GRAD
IPC: B28B17/00
Filed: 1976-12-02
Abstract: A measuring arrangement determines the amount of deviation of the dimensions of the workpieces from a nominal dimension. The device generates a signal which is fed to a control arrangement.
