Title: Processable thermoplastic composition and production thereof
Inventor: GUNNAA YANSON
IPC: C08L51/06
Filed: 1989-01-13
Abstract: In a thermoplastically processable composition comprising a continuous matrix of a thermoplastic polymer material and fine particles of a vulcanized rubber dispersed in said matrix, the polymer material contains hydrolysable silane groups and is hence cross-linkable by means of water and/or moisture absorption. An article can be formed out of the composition, using conventional thermoforming methods for thermoplastics, and after thermoforming the composition can be transformed to a fully cross-linked state. The composition can be produced by heat-treating a mixture of the thermoplastic polymer material containing hydrolysable silane groups, the rubber in unvulcanized form and a vulcanizing agent for the rubber at a temperature necessary to vulcanize the rubber, while subjecting the mixture to high shear to simultaneously disperse the vulcanized rubber thus produced, in the form of fine particles in the silane-containing thermoplastic polymer material.

Abstract: PURPOSE: To enable a part constituting the spring system to be changed and the initial set conditions of the device to be readily changed by making possible easy disassembling of the device in the device of detecting the abnormality of the apparatus contained in a hermetic vessel or the like from the vibrations of leaf springs.  
     CONSTITUTION: A mounting base 1 consists of a cover base 1a, intermediate base 1b and keep plate 1c. 2 denotes two sheets of leaf springs which are held and fixed in place between the base 1a and intermediate base 1b and the intermediate base 1b and keep plate 1c. Each of the leaf springs resonates at the specified vibration frequencies of the apparatus. 2a is the recess of the holding part, 2b a weight and 2c the screw fastening the leaf spring 2, recess 2a, weight 2b. If with this construction the spacing between two sheets of the leaf springs 2 is reduced by decreasing the height of the intermediate base 1b, the sandwiching quantity of the leaf springs 2 increases when a needle 5 is held in between, thus large vibrations become necessary until the leaf springs 2 vibrate and the contact parts with the needle 5 come apart. If the height of the intermediate base 1b is increased, the opposite of this results. Exchanging of this intermediate base base 1b may be readily  accomplished by removing the screw 1d.
