Title: Two-level needle plate for a sewing machine - providing a gap between needle plate and presser foot
Inventor: ROHR GUENTER
IPC: D05B73/12
Filed: 1978-01-10
Abstract: A two-level needle plate for a sewing machine, the front part of which is below the level of the presser-foot sole when the presser foot is resting on the rear, high-level part of the needle plate, creating a gap which extends beneath the presser foot sole for a distance equal to >=1 feed-stroke of the feed dogs. The length of the presser foot is greater than the slits through which the feed dogs operate. The leading edge of a workpiece can be presented to the feed dogs without encountering resistance from the presser foot, giving an easier, trouble-free start to a seam without rucking and without displacement of superposed fabric layers.

Title: Measuring distance between mobile radio receiver and transmitter - using relation between received signal intensity and separation distance
Inventor: WAECHTER FRIEDRICH DIPL ING
IPC: G01S11/06
Filed: 1978-11-14
Abstract: The method and arrangement are for determining the distance of a mobile radio receiver moving directly towards or away from a stationary transmitter w.r.t. the transmitter are partic. applicable to aircraft taking bearings on the transmitter. They enable the distance to be determined very economically, purely passively, and automatically from the received signal. This does not require special provision for distance measurement at the transmitter. The transmitter radiates at constant power and the distance is derived from the intensity of the received signal which decreases with increasing distance. The intensity of the received signal is measured either as the power of the signal or the field strength generated by it at the receiver. The intensity measured at the start of the measurement period is stored and used as a reference in calculating the intensity variation and distance.

Title: Friction-drive twisting head for sliver or slubbing - giving high-quality output at speeds up to 1000 metres per min.
Inventor: SCHMID REINHOLD
IPC: D01H5/28
Filed: 1979-08-29
Abstract: A twisting head for imparting false-twist or read twist to a silver or slubbing comprises a fixed carrier with a rotating shell within which is a pair of feed rolls driven by friction gearing. The silver is gripped between the feed rolls and simultaneously advanced longitudinally whilst being rotated around its axis. An electromagnetically-operated device effects intermittent disengagement of the feed drive and opening of the roller nip, permitting the twist to run in front of the rolls into the material in the storage can. The mechanism is capable of handling slubbings, etc., at speeds of 800-1000m/min., compared to a limit of 50 m/min., for twisting heads driven by positive gearing. It is quieter, suffers less wear, and produces high-quality, uniform slubbing or silvers.
