Title: Reduced emissions two=stroke IC engine - has separately lubricated piston which operates without oil being mixed with fuel
Inventor: KNOTT FRANZ JOSEF
IPC: F02B33/26
Filed: 1990-03-09
Abstract: A two-stroke internal combustion engine has a stepped piston which operates in a correspondingly stepped cylinder. An annular chamber is formed between the upper part of the piston, which has a smaller diameter and the larger diameter part of the cylinder. The piston is lubricated by injection oil into the annular chamber which is sealed off from the crankcase by the piston rings. The crankshaft and big ends are provided with sealed bearings so that there is no oil in the crankcase. The air-fuel mixture flowing into the crankcase is not mixed with oil and so no oil is burnt in the engine combustion chamber. USE/ADVANTAGE - Reduction of atmospheric pollution.

Title: Stacking process for flat cardboard blanks - produces gap in overlapping flow for undisturbed removal of stack
Inventor: WAGNER HEINZ
IPC: B65H33/12
Filed: 1990-04-25
Abstract: When stacking up flat blanks of cardboard etc the blanks are supplied on a first conveyor and taken up by a second conveyor which runs in the same plane and at times at the same speed and at other times at a higher speed. This higher speed conveyance takes place in only one individual stroke over a path corresponding at most to the length of the second conveyor and the overlapping flow is thereby pressed on the second conveyor at one point from above but otherwise is left lying free on the second conveyor. The second conveyor (6) is associated with a touch-down member (15) which at the lower speed is lifted from the overlapping flow (4) and at the intermittent rhythm can be pressed onto the overlapping flow and which can be moved with the second  conveyor at the higher speed in synchronization in the conveyor direction. USE/ADVANTAGE - Stacks of flat cardboard blanks can be built up evenly with sufficient time for their removal.

Patent DE-4025210-A1 (DE)
Inventor: JUSUPOW MALIK SARIFOWIC PROF
IPC: B60C23/06
Filed: 1990-08-09
Abstract: A process, devices and circuits allow tyre pressure changes to be monitored and indicated while on the move, based on the fact that the speed of rotation of the wheel, given the same speed of the vehicle, changes when the tyre pressure is reduced. According to this process, the speed of rotation of the wheel to be monitored is measured for a predetermined time period. The measurement is repeated later, the measurement time period being chosen so that it is inversely proportional to the speed of the vehicle. When the speed of rotation deviates, a signal is generated. Dry-reed magnetic switches linked to the wheels or cardan shaft of the vehicle, which may be mounted on the vehicle without constructive alterations thereof, are used as rotation speed sensors.

Title: Electronic circuit measuring combustible components of gas - uses catholytic temp.-dependent detector resistor and non-catholytic temp.-dependent compensation resistor
Inventor: MATTHIESSEN HANS
IPC: G01N27/18
Filed: 1990-08-16
Abstract: A temp. dependent detector resistor working catholytically is exposed to the gas to be analysed and is a temp. dependent compensation resistor without catholytic effect. These resistors are components of two bridge circuits with electronic measuring or regulating circuits. One of the two resistors (K,D) is switched as a common component of both bridge circuits (1,2). The other resistor is assigned to only one of the latter. A regulating amplifier (VR) is coupled to the bridge (1) serving as the regulating circuit. The latter controls the inputs (4,5) of the amplifier by a first electrical parameter. The oupput (6) of the amplifier holds a second electrical parameter of the regulating bridge constant. The measuring bridge (2) contains both resistors (K,D) and is coupled to a measuring amplifier (VM). The inputs (7,8) of the latter are controlled by an electrical parameter of the measuring bridge.  A measuring signal can be tapped from the amplifiers output (9). ADVANTAGE- Prevents overheating of detector resistor.
