Title: Cremating furnace with stacked combustion chambers - has flaps between chambers for controlled descent on simultaneous cremation
Inventor: STROHMENGER WERNER ING GRAD
IPC: F23G1/00
Filed: 1975-04-18
Abstract: The cremating furnace has a number of stacked combustion chambers. The lowermost chamber is closed by a flap on which is collected the cremation matter from the combustion chamber above. The stacked arrangement of combustion chambers ensures that the number of cremations carried out in the same period can be doubled and it ensures that no mixing can occur when operated according to regulations. The lowermost chamber has a lower flap which collects the material for further cremation after actuation of the upper first flap. In the region of the first flap (11) seals are provided which seal the lowermost chamber (14) against the combustion chamber (10) above when the first flap is closed. Two interlock devices prevent irregular opening of the flaps.

Title: Plasma microwelding with increased gas vol. and pilot arc current - to facilitate striking the main arc
Inventor: LANGHANS ADOLF
IPC: B23K10/00
Filed: 1975-06-03
Abstract: Plasma welding process, esp. for microwelding a transferred arc where electric power is applied between burner-electrode and -nozzle to form a pilot arc ionising plasma gas fed between electrode and workpiece; a second power supply (2) is then applied between electrode and workpiece to form the main arc. The novelty is that to strike the main arc, the amt. of plasma gas and/or power is temporarily increased above the values used for welding. The pref. increase of gas or power involves a factor of 1.3-3.0, esp. 2.0. Two power supplies are pref. used, the negative pole of the pilot supply being connected to the electrode, whereas the positive pole of the main arc supply is connected to the workpiece. The process is used for example, in welding sheet, foil or wire, 0.05-1.0 mm thick, of high alloy steel, Cu, Cr-Ni, Ti, etc. where it is easy to form the main arc by using the invention.

Title: Separator for dust particles in gas stream - consisting of two parallel plates one with slots the other of strips
IPC: B01D45/08
Filed: 1975-07-28
Abstract: Small dust particles are removed from a dust laden gas stream in a process where the gas is accelerated to a velocity of 400 ft/min and caused to traverse a surface of surfaces imputing onit, and issuing fro it with a velocity of 4000 to 6000 ft/min. The surface contacting the gas is perforated, roughened or in some other way arranged so that the viscous boundary layer becomes turbulent and thus maximises the dust collecting effect of the surface. Used to separate fine dust particles (2 mu) from gas streams. This type of process is known but tends to consume a very large amount of energy due to the high pressure drop and velocity used. The process described reduces this energy requirement.

Title: Linearising circuit for measuring probes - uses summing amplifier with decade selector switch for matching non:linear characteristics
Inventor: KOLB FRANZ
IPC: G01R15/00
Filed: 1975-10-04
Abstract: The linearising circuit for measuring probes with nonlinear characteristics consists of a zener diode-stabilised voltage source across which is connected a first operational amplifier. The sensitive measuring element (e.g. resistance thermometer) is connected in the amplifier feedback loop. The output of a second amplifier at a slope of about 30m V/deg.C is connected to the non-inverting input of the output amplifier. Two voltage-follower amplifiers are fed from decade selector switches connected to precision resistors across the supply. The second bank of the ganged selector switch connects further resistors in the feedback loop of another operational amplifier which drives the output amplifier. A point-slope matching of the summing amplifier gain to the non-linear sensor characteristic is thus obtained.

Title: Heat pump for central heating - has additional heat drawn from exhaust of internal combustion engine to drive compressor
Inventor: KAMPFENKEL OTTOMAR DIPL ING
IPC: F24D11/02
Filed: 1976-02-04
Abstract: The heat pump (1) has an expansion valve, and evaporator, a condenser and a compressor which is driven by an internal combustion engine. Heat taken from an outside source in the evaporator is given up in the condenser to raise hot water in a central heating circuit. The hot water from the condenser passes through an auxiliary heat exchanger (12) in the exhaust of the internal combustion engine. The waste heat from the engine is thus added to the heating medium to increase the overall efficiency. Valves in the heating return can be operated to make the flow bypass the heat pump so that the whole of the heating is obtained from the engine exhaust while the engine runs on no load.
