Title: Polyurea dispersions in organic isocyanates
IPC: C08G18/32
Filed: 1983-08-23
Abstract: A dispersion of a polyurea in an aromatic polyisocyanate is prepared by mixing the polyisocyanate with one or more aliphatic diprimary diamines having (a) at least one amine group attached to a carbon atom having not more than one hydrogen atom attached thereto or (b) at least one amine group attached to a carbon atom which is itself attached to a carbon atom having not more than one hydrogen atom attached thereto, provided that both amine groups are not attached directly to separate rings of an alkylene-linked polycyclic aliphatic ring system. The reaction preferably takes place at a temperaure in the range 20°C to 60°C. The polyurea dispersion products are useful for manufacture of polyurethane foams and elastomers of superior physical properties.

Title: A reel for registry of a material web provided with crease lines
IPC: B65H23/04
Filed: 1984-03-21
Abstract: @ In the processing of a material web provided with crease lines a reel is used frequently for registry. The reel comprises one or more axial rules, the distance between these being adapted to the distance between transverse crease lines of the material web. To ensure a correct engagement with the crease lines, the rules are relatively sharp which may cause damage to the material web. This is prevented in accordance with the invention in that supporting elements are provided at the end of the rules so that any material extending beyond the ends is not folded or broken. The reel moreover comprises adjustment facilities for adapting itto varying distances between the transverse crease lines of the material web.

Title: Ink drop velocity control system
IPC: B41J2/07
Filed: 1985-07-10
Abstract: 57 A method and apparatus are disclosed for providing feedback control of the ink drop velocity in a drop marking system. The control system maintains essentially constant velocity of the ink drops as they pass through a deflection field which causes certain of the electrically conductive drops to be directed onto a substrate to be marked. The ink flow between two selected points is monitored by a control device to generate ink flow rate data and compared against a reference value. In the event that a flow rate deviation is sensed, appropriate action is taken to change the flow rate. Such action includes altering ink viscosity and/or ink pressure.

Title: Process for butt-welding plastic pipes, and welding element therefor
IPC: F16L47/02
Filed: 1987-03-05
Abstract: In order to weld butt-jointed plastic tubes, a welding element with a wire coil for electrical resistance heating is positioned between the abutting tube ends. The tube ends are pressed to each other while at the same time the welding device is heated to welding temperature. Lastly, the tube ends are held together until the welded area has hardened by cooling. The welding device is constructed in the form of an annular disc the external diameter of which is approximately equal to the external diameter of the tubes and the internal diameter of which is approximately equal to the nominal internal diameter of the tubes. A heating wire coil spirals around the geometric center of the annular disc, and is positioned on the two annular disc surfaces that come into contact with the tube ends.
Patent EP-0243625-A3 (EP)
IPC: H02P23/00
Filed: 1987-03-10
Abstract: A DC motor is speed regulated by continuously, maintaining 
current in the motor windings and varying the current between 
a higher and a lower current level during a subsequent sector 
or period of rotation in accordance with the velocity sensed 
during the present sector or period of rotation. To obtain 
closer regulation, the higher and lower current levels have 
only a small amplitude difference and the system is adaptively 
controlled by sensing the number of sectors of a series of 
such sectors during which the higher current level is supplied 
to the motor. If the percentage exceeds 70%, both current 
levels are incrementally increased and if the percentage is 
less than 30%, both current levels are incrementally 
decreased. The regulation and adaptive control are used in 
two stages, initially sensing velocity during each revolution 
of a series of 20 revolutions and switching, when 
synchronized, to sensing velocity during each of 74 sectors of 
a series that form one revolution.

In order to solve this problem, the receiver coil (16, 18, 20, 22) is arranged according to the invention inside the transmitter coil (14). By using more than one receiver coil, the housing forming the probe is subdivided by webs. In the troughs (26) thereby produced, the various receiver coils (16, 18, 20, 22) are arranged inside the transmitter coil (14). <IMAGE>

Title: Process and apparatus for the continuous thermal treatment of a moving textile web
IPC: F26B23/02
Filed: 1987-12-03
Abstract: The thermal treatment of a continuously moving textile web takes place by means of hot gas in a treatment apparatus having at least two successive treatment zones. The entire waste gas of the first treatment zone is introduced into the second treatment zone as fresh gas once it has been heated up. A partial waste-gas stream drawn off at the end of the second treatment zone undergoes secondary combustion. The partial waste-gas stream thus heated first of all warms the second partial waste-gas stream coming out of the second treatment zone, following which, before its discharge into the atmosphere, the partial waste-gas stream coming out of the first treatment zone and then also the fresh air are heated. In this way, extremely cost-effective operation of the entire treatment apparatus is achieved at the same time as reliable waste-gas cleaning and disposal.
