Title: IC engine exhaust duct sub-assembly - comprises open ended hollow extruded heat exchange section between end pieces with air cooled by=pass duct
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/16
Filed: 1978-09-05
Abstract: The IC engine exhaust duct sub-assembly has a long open ended hollow section, pref. extruded, held between end casings. Hot gas flowing past one side of the section transfers heat to cooler gas on the other. Some hot gas may be diverted through ducting (7, 8) inside this heat transfer section (17), with an annular passage (11) for cooler gas between. To minimise the risk of problems with low hot strength of the extruded mateiral, ambient air is drawn through this passage. The air enters via pipes (12) of relatively small total x-sectional area.

Title: Gasification of carbonaceous materials - by cooling liq. slag with water jet and mixing steam produced with primary burner gas, improving thermal efficiency, minimising pollution
Inventor: STAUDINGER GERNOT PROF DIPL IN
IPC: C10J3/08
Filed: 1979-05-23
Abstract: The process comprises gasifying carbonaceous dust in a burner, with oxygen or a gas contg. oxygen and water vapour and possibly an addn. of CO2. The primary gas thus obtd. is conducted through a bulk of larger pieces of carbonaceous material in a vertical gasifier, forming an under pressure, producing gas and forming a liq. slag. The liq. slag is received in a slag bath and is made to flow over a weir into a bath of cold water provided in the gasifier. The liq. slag is divided during its free fall between the weir and the cold water bath by jets of water. The slag is cooled and the steam formed is brought to the lower free surface of the bulk of larger pieces of carbonaceous material to form part of the steam necessary for the process. The process is more reliable and more efficient economically than existing processes. Better use is made of the heat in the liq. slag and pollution of the environment is less.

Title: Output stage for heart pacemaker - has complementary pair of transistors to use discharge current for stimulation
Inventor: BLASER REINHARD DR ING
IPC: A61N1/362
Filed: 1979-06-27
Abstract: This circuit of an output stage of a battery driven heart pacemaker fully exploits the electrical energy normally wasted when a coupling capacitor is allowed to discharge. In this circuit both the leading and trailing edge of the pulse which forms the input to this circuit are used to produce spikes to stimulate the heart muscle. The capacitor (3) is charged by the battery voltage (Ub) through the heart impedance (1) whilst a transistor (4) is turned on by the rising edge of the pulse. At the end of this charging period another, complimentary transistor (5) is turned on by the falling edge of this pulse, resulting in discharge through the heart impedance. The time constant formed by the product of the capacitance and the heart impedance is about one third of the pulse width.
