Title: Moulding substrate plus decorative cover - preventing decorative area from being stretched by holding materials 1st where little deformation occurs and then pressing shaped area
Inventor: RIJCKEVORSEL JACQUES VAN
IPC: B29C51/14
Filed: 1990-03-15
Abstract: A process bonds together a rigid but mouldable substrate and a flexible decorative covering under heat and pressure between male and female tools to produce e.g. the interior covering of a car door which has at least one much deformed and at least one little deformed zone to display the decorative effect visually. In the first stage the zone which is only slightly deformed is moulded under 0.5-20 bar pressure; in a second stage the other zones are moulded while the first zone is held in its position. A preferred rigid substrate is a polyolefin film with high cellulose filler content; preferred decorative material is a fabric with  decorative motive. ADVANTAGE - The process eliminates the problems of distorting the decorative areas. It enables decorative coverings to be made with two different materials whose dividing line is in the little deformed zone, and it ensures accurately positioned dividing line.

Title: Power semiconductor switching off method for switch protection - has discharge of switch capacitance before turn off only in overload conditions
Inventor: BROSCH HARALD DIPL ING
IPC: H03K17/695
Filed: 1990-04-18

Title: Supply of energetic flow of water into two neighbouring parts - consists of tilting device with two chambers to discharge water into compartments
Inventor: NILL WERNER
IPC: B01D21/24
Filed: 1991-02-20
Abstract: A device for periodically distributing a flow of water to two separate areas consists of a tilting element (3) with two chambers (11, 13) each of which has a water outlet (29, 31). This element tilts about an axis located between the two chambers. During the filling of one of the chambers, the lower walls (5, 6) of the chambers lie at an acute angle to the vertical, so that when the chamber is full the element tilts and the contents of the chamber are delivered in an energetic stream. The second chamber then assumes a stable horizontal position and commences filling. The outlet openings are at an angle (alpha) to each other, and the lower walls are at an obtuse angle (beta) to each other. The angle (alpha) lies in the range 45 to 120 degs. while the angle (beta) is between 220 and 90 degs.. The two chambers may be of different sizes, in which case a balancing couterweight is required or the axis is displaced towards the larger chamber. USE/ADVANTAGE - Used for providing a distributed energetic water flow, especially in waste water treatment plants. Provides a means for effective rinsing of neighbouring areas such as tanks, filters of channels, automatically and at low cost.

Title: Balancing film shrinkage during thermoplastic container mfr. - using heating strips which are positioned under longitudinal and lateral film edges between preformed containers between deep-drawing and punching stations
Inventor: WALTER KURT DIPL ING
IPC: B26F1/40
Filed: 1991-05-11
Abstract: To prevent lateral shrinkage after heat forming of thermoplastic film containers, a film strip is drawn forward at regular intervals through preheating, forming filling, covering and stamping stations. During strip progress through the machine a sensor controls the operation of the final processing stations in relation to the position of the deep-drawn containers. Prevention of shrinkage laterally across the film when the machine stops is achieved by maintaining the film temp. at the deep drawing temp. as it passes between the deep-drawing and punching stations. The film temp. is maintained between containers by heating strips positioned under the longitudinal and lateral edges between containers. USE/ADVANTAGE - The process and device are used during mfr. of containers, esp. in polypropylene film on a forming, filling and stamping machine and prevent lateral film shrinkage during machine stops giving a uniform edge around each container.
