Title: Spinning by feeding fibres between two surfaces - moving in opposite directions and through which air flows pass to assist in twisting
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D01H4/00
Filed: 1976-12-15
Abstract: A yarn is spun by feeding fibres into a nip formed between a pair of surfaces moving in opposite directions. Air current are fed through the respective surfaces so that the resultant vector forces on the fibres and produced by the movement of the surfaces and air currents act in a circular direction around an axis around which the fibres and twisted to form the yarn. Neither air current acts in a direction opposite to the twist direction of the yarn, thereby producing a better twisted, more uniform yarn.

Title: Mortice lock key retention device - has clip with spring section inserted into keyhole and upper cup pushed into guide over lower cup
Inventor: BODENSTEIN HANS
IPC: E05B17/14
Filed: 1976-12-22
Abstract: The key protector is used to prevent the dropping out of a key from a mortice lock. A spring clip is introduced into the keyhole to prevent the key from being removed. The key can be removed only by eliminating the spring pressure from that side of the door in which they key was inserted. The key neck is held by two flexible arms with slight friction contact. This prevents automatic rotation of the key but not intentional rotation of the key for door locking. The blocking arrangement has three parts, a spring section inserted into the key hole and guide cup for the springs and an upper cup pushed into a guide over the lower cup. A firm connection is established between the two cups and the spring is loaded against the opening direction of the key.

Title: Winding of starter spools for open=end spinning - using yarn taken directly from one spinning head of the machine
Inventor: KAMP HEINZ
IPC: B65H51/22
Filed: 1978-02-22
Abstract: One end is wound onto a metering drum whence it is subsequently withdrawn by an intermittently operating winding head in a manner which preserves the original direction of travel of the yarn to form the starter spools. The metering drum may have a sufficient capacity to provide several starter spools without replenishment, and is provided with maximum and minimum sensors which control the speed of the starter-spool winder or the drive to the metering drum. The starter yarn is not reversed in direction compared with the rest of the spool, there is no possibility of getting a spool with the wrong type of starter yarn, and the starter yarn spinning can be used as a normal production head once a sufficient stock of starter spools has been wound.
