Title: Heavy duty tandem axle - has balancing double arm seated partly in suspension body with relative eccentricity
Inventor: LAUBKEMEIER GUENTER
IPC: B60G5/04
Filed: 1974-01-23
Abstract: On heavy duty vehicles with tandem axles which mostly operate on uneven surfaces the advantage of providing spring suspension is often omitted. Such vehicles however are limited in their maximum speed by stipulations of the law. On the other hand spring suspensions of any kind, but leaf spring suspensions in particular, present possible failure risks due to spring fatigue or breakage. The present arrangement overcomes this by seating the balancing arm in such a way and the other part of the suspension axle in the balancing arm and the other part seated in the suspension body have a relative eccentricity, so that in case of the swinging motion of the arm the axle performs a rolling motion which demonstrates itself as a simulated springing action.

Title: Caffeine extraction from coffee by solvent treatment - esp. coffee beans without alteration of taste or aroma
Inventor: DALLINGA HELMUT
IPC: A23F5/22
Filed: 1974-10-26
Abstract: Decaffeination of coffee, esp. raw coffee beans comprises mixing the coffee as extract or beans, with a solvent for the caffeine; and subjecting the mixt. of solvent and coffee, before heat is applied, to a predetermined pressure greater than the vaporising pressure of the solvent at the highest working temp. the pressure being exerted by an inert gas such as nitrogen. Pressurised water may also be introduced into the processing vessel so that it may be used for opening up the raw beans simultaneously with the extraction of the caffeine. The minimum pressure of the inert gas in that case, is set higher than the vaporising pressure of the water. During operation, the pressure is raised and lowered, from and to the minimum, periodically. Quicker and more economical method, handling the beans more gently eliminating losses of coffee extract due to breaking down by the boilding of the solvent at high temp.

Title: Magnetically levitated railway system - has flexibly mounted damping solenoids facing levitating and guiding solenoids on the vehicle
Inventor: MIYASHITA TAKAO
IPC: B60L13/04
Filed: 1975-01-21
Abstract: The magnetically levitated railway system stability is improved by the use of damping solenoids. The coach body has supporting and guiding solenoids which act in conjunction with the secondary conductor in the track. Each of these solenoids is faced by a damping solenoid whose current can be varied in relation to coach body oscillations. The damping solenoids are fastened on the coach body with higher flexibility than the supporting and/or guiding solenoids. As a result the damping solenoids and supporting solenoids move independently relative to the secondary conductor. The current used for damping is very low. The forces in the overall magnetic system compensate for unevenness in the track.
