Title: Coin operated vending machine - checks number of coins with latch arm in coin channel and has other arm in programmer bar recess
Inventor: GRUENIG DIETER
IPC: G07F5/06
Filed: 1979-04-21
Abstract: The improved design of a vending machine coin release mechanism is due to the fixed position of the shaft where the coins required for goods issue are collected.

Inventor: KRUMM KARL
IPC: B02C4/02
Filed: 1980-10-04
Abstract: The stone crusher has two belt driven rollers (5,6), between which the material (10) is fed, while they are rotated towards each other.
