Title: Particle grader with external blower - has vertically adjustable baffle ring fixed below thrower disc to control vertical component of spiral air flow
Inventor: UHLMANN JOHANNES DIPL ING
IPC: B07B4/02
Filed: 1991-10-23
Abstract: A particle grader with an external blower has a vaned cage (4) from whose interior the fine particles are extracted.

Title: Seat belt with an elastic restraint system
Inventor: HUBER WALTER DIPL ING
IPC: B60R22/28
Filed: 1993-05-27
Abstract: The invention relates to a seat belt (safety belt), characterised in that in contrast to the conventional belt it makes full use of the theory of elasticity. In a simple case this can be brought about by virtue of the fact that the belt itself has a predetermined measure of elasticity serving for the purpose of its use. However, it is more effective to attach elastic devices between the belt and belt anchorage points. These may be steel springs, gas-filled compression springs or other elastic components. The improvement over the prior art (inventive step) consists in the fact that as a result of a certain measure of elasticity and a certain mode of operation the protective effect of the belt is increased many times. <IMAGE>

Title: Spinning frame - has standard frame for various types of spinning and accessible for standard robot to service it.
Inventor: LATTION ANDRE
IPC: D01H7/02
Filed: 1993-07-07
Abstract: A process to produce spinning machinery having a drafting system to accept roving, and to wind the yarn on a driven rotary support. The several lengths of the total height between drafting and the spindle base can be so chosen that certain details are established as constant for all frames. The appts. used is also claimed. Typically the roving (22) is taken through the rollers (23) of the drafting system (2), and from this point to the tip of the rotary system (1), the distance (F), including guides and ballooning, is constant. This leaves the rotary system, which consists of (d1 + c + d3), which is also constant. As the spindle base (12) may be a motor, or just a bearing, this measurement (d3) between spindle foot and top of spindle rail, is a constant. ADVANTAGE - One standard frame is acceptable for all types and sizes of spinning arrangements. Excess adaptability is avoided, with economic advantages. Robotic accessories would operate on any standard frame.
