Embodiment

[0183] Specimens comprising polybutylene terephthalate (PBT) as the thermoplastic were prepared and tested. The matrix (A) used was Celanex(R) 2002 (Ticona GmbH) added to 100%. Percentage data in terms of composition of matter refer to wt%.

[0184] If the example included recording Cu as component B1), the photosensitive compound used contained 0.2% copper phosphate hydroxide (commercially available from the company Aldrich). If the example contains the entry Sn / Cu as component B1), the photosensitive compound used is an additive powder containing both tin(II) and copper(II) as cations from the company Chemische Fabrik Budenheim KG. The additives were used in the form of unreacted mixtures of individual salts (approximately 80% tin(II) phosphate and approximately 20% copper(II) phosphate hydroxide) to prepare molding compositions.

[0185] If the example includes the entry of Ti as component B2), the photosensitizing oxide used comprises 1.0% of titanium dioxide in the form...

Abstract

The subject invention discloses a variety of different maintenance devices for use with a filling valve apparatus. The maintenance devices each include a movable component and a locking mechanism. An actuator of the locking mechanism is coupled to a caming section of the movable component for moving the movable component between a release position with a rim of the movable component spaced from fingers of the locking mechanism and an engaged position with the rim abutting the fingers. The fingers are wedged between the movable component and the filling valve apparatus when the movable component is in the engaged position for securing the device to the filling valve apparatus.

Description

technical field [0001] The present invention relates to novel molding compositions based on engineering thermoplastics which are halogen-free flame-retardant and which can also be laser marked. The invention also relates to the moldings produced from these molding compositions. Background technique [0002] Thermoplastics have been used as materials since a long time. In addition to the mechanical, thermal, electrical and chemical properties of these materials, functionalities such as the ability to mark with lasers are gaining more and more attention. For example, applications in the field of household products, in keyboards and in the field of electronic equipment should be mentioned. Here, the application requires a high contrast between the laser-inscribed marking and the polymer matrix as background. [0003] In addition, the market is increasingly interested in halogen-free flame-retardant thermoplastics. The basic requirements for flame retardants here are: the lo...
