Title: Nitrous oxide as energy source - in torque-generating combustion engines, or for assisting in motor ignition
IPC: F02B47/00
Filed: 1973-10-10
Abstract: Nitrous oxide is used, opt. with other known fuels, in combustion motors producing torque, e.g. in petrol or diesel engines for vehicles. It is also used to assist ignition in such motors of fuels which ignite with difficulty. (1) N2O is an endothermic cpd. which decomposes when exposed to a spark evolving heat, according to the equation 2N2O = 2N2 +O2+39 kcal; (2) it has high oxidising power, giving up oxygen very readily, so that fuels burn in it more readily than in air. (3) it does not combine with water, oxygen or NO and forms no corrosive cpds. (4) it explodes by appropriate ignition in presence of hydrogen or CO, to give nitrogen and waer or CO2; (5) it is non-polluting and causes no loung damage, (6) it can be used in liquefied form, e.g. in steel cylinder, (7) it requires no expensive refineries as used for petroleum, (8) i decomposes into nitrogen and oxygen, the existing constituents of air and (9) its use would allow reduction in dependence on imported energy carriers.

Title: Formed plastic piece for wiper blade - is plastics plug forming blade hinge and providing electrical and vibration insulation
Inventor: BAUER KURT
IPC: B60S1/38
Filed: 1973-11-02
Abstract: The plug of the plastic hinge piece is inserted upward between the sides of the wiper arm until the bored holes in the plug align with the holes in the wiper arm. The plastic flaps connected to the base of the plug are then folded upward around each of the sides of the arm and the bosses situated in the flaps are entered through the holes in the arm sides and into the holes in the plug. This whole assembly is inserted into the wiper carrier which the outsides of the flaps of the plastic hinge are formed t fit. Protrusions on the plastic hinge piece retain the whole hinge in the wiper carrier and prevent excessive movement.

Title: Natural draught roof ventilator for habitable rooms - has wind deflection plates attached to fixing frame
Inventor: GREFE HELMUT
IPC: E04D13/035
Filed: 1974-02-21
Abstract: The roof ventilator has a rectangular frame with a horizontal flange which is used to attach it to the roof. It has an opening with upper flaps which can be adjusted to close, partially open or completely open the ventilator for natural draught flow through it. Side plates are fixed by brackets to the outside of the frame so as to leave a gap between the side plates and frame and a space between the bottom of the side plates and the roof. The effect of wind movement through the space between side plate and frame is to induce uniform flow through the ventilator opening. The side plates can be curved or inclined for effective action.

Title: Rotary I.C. engine driven by gas mixture explosions - uses pulsating heavy pistons moving without connecting rods
Inventor: POPESCU RAUL-FLORIAN DIPL ING
IPC: F01B13/06
Filed: 1974-03-27
Abstract: Rotary engine driven by gas mixture explosions has radially pulsating heavy free pistons. It may have one, two, three or four pistons and a rotating cylinder block. There are given ratios between the weight of the radially free-floating pistons and the operating speed determining the centrifugal and radial pressures of these pistons and the average effective work output.

Title: End twisting appliance for sweet wrapping machines - uses wrapping material to control advance of twisting head
Inventor: HOGENKAMP WILHELM
IPC: B65B51/00
Filed: 1974-04-26
Abstract: The wrapping machine has a twisting head, with clamp jaws, actuated by a control drive to open and close them. The jaws engage on the wrapping material projecting over the sweet, and twist them. The head ans jaws are freely displaceable within the longitudinal axis of the twisted material. The rotary drive for the head, and the control drive for the jaws, both permit a degree of free play, to allow the axial displacement of the head. The head is carried on a hollow shaft, longitudinally displaceable in a housing. The shaft carries a drive gear, meshing with a gear, to drive the head. The gears are dimensioned and positioned, so that they are maintained in engagement, during axial displacement of the shaft.

Title: Self loading container lorry - with tipping load platform and cable winch to haul container onto platform
Inventor: BOCK MANFRED
IPC: B60P1/64
Filed: 1974-05-08

Title: Water deaeration tank - with immersed steam pipes and additional steam distribution system above water level
Inventor: KREMER HERMANN-JOSEF
IPC: F22D1/28
Filed: 1974-08-08
Abstract: A deaeration tank for water which is sprayed through nozzles above a maintained water level is fitted with steam distributor pipes above the water level and submerged tubes with outlet apertures below the water elvel. An additional steam feed with outlet ports above the water level is equipped with a regulator which opens when a certain pressure or pressure difference in the steam pipe is reached. This ensures satisfactory operation of the deaerator even when the steam volume suddenly rises; it prevents effectively a rise of the water level caused thereby which would make it inoperative.

Title: Stirrer for mixing gases into liquids - having hollow shaft with gas feed and pair of aerofoil section flights
Inventor: BONU BONU DIPL ING
IPC: B01F3/04
Filed: 1975-01-10
Abstract: Stirrer for mixing gas into a liquid consists of a pair of aerofoil section flights attached to a hollow shaft one above the other with a gas inlet line from the shaft discharging the gas through a nozzle into the space between the flights. A hollow flight is used for the gas inlet line so shaped that a slot type opening runs along its rear edge w.r.t. rotation direction, discharging at the pt. of smallest gap between the upper and lower flights. It connects with the hollow shaft. The pair of flights can be inclined at various angles to the shaft, starting at zero. For use in systems where gases are to be mixed with liquids. Because it does not rely on turbulence for the mixing effect, with vortex shedding, its power consumption is lower than comparable mixers.
