Title: Efficiently removing all blowing gases from foam plastics - by heating the material in hot air draught while it is moved by revolving screw up inclined tube, collecting and liquefying gases liberated.
Inventor: ADELMANN WALDEMAR
IPC: B29B13/10
Filed: 1992-07-27
Abstract: In a process for the removal of blowing agent gases such as fluorochloro-hydrocarbons or pentane from foam plastics the plastic material is heated to a temp below its decomposition temp and below the flash pt or decomposition temp of the gas but above the degassing temp. The heating is continued for a time and the gas evolved is collected, drawn off and, preferably, liquefied. Typically the plant used has an inclined oven (2) containing a rotating screw (3). The material is fed in from the pipe (6) to the inlet (4) which has another inlet (5) for the supply of hot air. The material is moved up the oven by its screw (3) which is turned by the drive motor (7). The degassed residue leaves the oven at the top and drops into the hopper (8) to a briquetting press (9) which consolidates it before it is removed (10). The plastic material is thus heated by the hot air which is applied at a suitable temp.

Title: Conversion part for improving the running gear in the case of motor cycles with front-wheel suspension by means of a telescopic fork
Inventor: WILDSCHREI-KOESTER DIRK
IPC: B62K25/18
Filed: 1993-04-07
Abstract: Many motor cycles are fitted with a telescopic fork for the front-wheel suspension. In particular in operation with a side car there sometimes occur extreme distortions of the fork. Conversion to a shorter castor for the purpose of easier steerability is hardly possible. The invention prevents the distortion by means of a guided reinforcing bar which also permits the front-axle castor to be changed. In order to prevent distortion of the telescopic fork 6, the two fork struts are connected to a bar mounted in pivot bearings 7 at the height of the telescopic-fork axle socket. Behind the front wheel supporting stays 5 are passed by means of pivoting bearings 2 from the bar to the lower fork-clamping head. Fastened to these supporting stays or to the bar is the brake anchoring means 4 which prevents the fork from nose diving. The castor can be established by extending the bar forwards and providing a new axle socket 9. The invention can be fitted in a simple manner to an existing telescopic fork (motor cycle with side car conversion). It represents a simple possibility for conversion which ensures optimum improvement to the running gear in mass production and production on a small scale. <IMAGE>
