Title: Printing machine for laminated material in textile industry - has central rotating drum with printing cylinders around circumference
Inventor: SASSI ENZO
IPC: B41F17/00
Filed: 1974-11-12
Abstract: The central drum has a dressed rubber layer which ensures that the outer surface of the drum on which the printing is undertaken is even and precisely cylindrical in shape. The surface of the drum has a cleaning and a drying units arranged in series after the printing cylinders in the direction of rotation of the drum. The cleaning unit has brushes which rotate in the opposite direction to the drum as well as a washing liquid spray.

Title: Electronic slippage measurement instrument - is for measurement tasks in driving systems and derives measured value from pulse width increase
Inventor: WILHELMY LOTHAR DR ING
IPC: G01P3/60
Filed: 1975-04-16
Abstract: The measured value is proportional to the slippage, the start of pulses is determined by rectangular pulses corresponding to the nominal number of revolutions and the end by rectangular pulses corresponding to the actual number of revolutions effected by the slippage. The time average value of the pulses derived is directly proportional to the slippage. The pulses (P1) are derived from the nominal number of revolutions (no) and the actual number of revolutions (n1) from which the pulse width difference (P2) is obtained. At a point of time (T2') starts a new pulse cycle. AC voltages are converted by rectangular pulses by Schmitt triggers.

Abstract: Polyethylene of high bulk density is produced by contacting C2H4 at a press. of 1-100 atmos. and a temp. of 10-110 degrees C with a suspension in an inert liq. hydrocarbon of a solid, particulate co-ordination catalyst consisting essentially of the reaction prod. of a halide, alkoxide or acetylacetonate of a Gp. IVa or Va transition metal and a hydride or organometallic reducing agent based on a metal of Gp. Ia, IIa or IIIb on a Gp. IIa, IIIb, IVa or IVb metal oxide or carbonate as carrier (I). To prepare the catalyst, (I) is damped with H3BO3 which is converted to B2O3 by heating in inert gas at 150-500 degrees C, the B2O3 coating is brought into contact at 25-300 degrees C with the transition metal cpd. until 0.1-15 wt% has reacted and the valency of the transition metal is reduced by reaction with the reducing agent. C2H4 is polymerised by vigorous stirring in contact with the catalyst suspension. C2H4 is polymerised at high speed and at good yield to a powder at high bulk density and high mol. wt. which is well suited to rotational moulding or powder coating techniques.

Title: Immobilising device used against enemy fighting vehicles - deposits hard setting foam plastics stored in container on missile
IPC: F41H9/00
Filed: 1975-11-18
Abstract: The means for inactivating enemy fighting vehicles, ships and aircraft uses container filled with foam forming substances. When the container is destroyed then a hard setting foam is rapidly generated. This foam blocks completely or partly the moving parts of fighting vehicles such as tank tracks. The air passages to the engines are fully or completely blocked. This foam also covers the observation or aiming devices with nontransparent layers. The containers are transported to target by suitable projectiles such as guided rockets, projectiles, bombs or unmanned missiles. They can be used also as mines. The rapidly hardening foam can be electrically conductive and hence it will circuit for example antenna or by forming a shield.
