Title: Presser finger palm for spinning frame flyer - has guide groove of uniform floor thickness and large radius edge
Inventor: GALLINA KURT
IPC: D01H7/32
Filed: 1980-06-21
Abstract: Presser finger for the flyer of a spinning frame has a palm of rectangular shape, with a guide eye for the slubbing into which leads a guide-groove of increasing depth whose floor is of uniform thickness throughout its length, the opposite face of the palm having a corresponding ridge of increasing height. The edge of the groove entering the guide-eye has a rounded rim whose radius corresponds to the thickness of the floor of the groove. The palm is produced by pressing between a pair of dies, in the lower of which is a groove corresponding to the shape and size of the ridge on the rear face of the palm. The palm is simpler and less expensive to produce than previous designs, as it requires no finishing machining. The large radius at the guide-eye reduces disturbance of the slubbing and is less susceptible to abrasive wear.

Title: Time level measurement of sonic or ultrasonic transition - performs dead-time adjustment involving amplitude monitoring and gain variation
Inventor: KECH GUENTER
IPC: G01F23/296
Filed: 1980-08-26
Abstract: Fill level measurement involves the use of a transducer emitting and receiving acoustic or ultrasonic waves and measuring the transition time between emitting the wave and receiving its echo. The corresp. equipment can be adjusted for the dead time of the ultrasonic or sonic transition time. The oscillation amplitudes of the transducer are monitored w.r.t a boundary value. When the amplitude faces below the threshold after a defined delay time the transducer is enabled to receive echo waves and/or the signal processing circuits receiving the output of the transducer are enabled to receive echo signals. After the pause delay is over, the gain of the circuit receiving the echo signals is increased uniformly, with time. The repetition frequency is small compared to the rate of gain change.

Title: Process and apparatus for the production of monofilament yarns
Inventor: MAAG FRITJOF DIPL ING DR ING
IPC: D02J1/22
Filed: 1981-03-10
Abstract: Multifilament yarns are spun and are divided into monofilament yarns. A multifilament yarn is unrolled from a spinning bobbin (1) and driven by a driving roller (2) and is drafted in a drafting unit (3). The residual shrinkage of the filaments is reduced in a fixing device (4). By means of the separating device (5), the multifilament yarn is divided into monofilaments (6) and wound on to the bobbin (8) with adjustable tensile force via the thread guide (7). A plurality of spinning bobbins can be presented simultaneously to a separating device, and the multifilaments can be predivided before the drafting. Before separation, the adhesion of the individual filaments to one another can be reduced by a preparation and by the rapid change of the tensile force in the filaments. The tensile force in the monofilaments is applied via the winding system which can consist either of a ring, ring traveller and spindle or of a spindle driven directly by an electric motor, the driving torque of which is regulated. <IMAGE>

Title: Two-stroke diesel engine with opposing free pistons
Inventor: WAGNER ALBERT
IPC: F02B75/02
Filed: 1981-03-24
Abstract: The invention relates to a two-stroke diesel engine with opposing free pistons, which are connected to thin pump pistons of a hydraulic pump. With complete balancing of the masses in each cylinder, the reciprocating movement of the opposing free pistons due to the hydraulic oil or pressure water delivered by the hydraulic pump is translated into rotary movement by a hydraulic motor and/or a free jet turbine. The return movement of the free pistons is produced by buffer air in buffer chambers on the free pistons. On the injection pumps driven by compression air the injection quantity is automatically controlled by the delivery pressure of the hydraulic pump. The scavenging air is delivered by an exhaust gas turbo-charger. Starting is produced by compressed air and starting injections. By switching the pairs of cylinders functioning independently of one another, the speed of rotation of the hydraulic motor and/or the torque of the free jet turbine is regulated. Of simple construction without crank drive or valves, the proposed diesel engine has a lower power-to-weight ratio and a lower fuel consumption and is suitable for the hydrostatic and the hydrodynamic driving of vehicles, ships, conveying systems, pumps, compressors and power generators. <IMAGE>

Title: Drive especially for up-and-over doors and the like
Inventor: CORONA HEINZ
IPC: E05F15/614
Filed: 1981-05-27
Abstract: A drive for an up-and-over door is accommodated within a rotary-bearing post. It consists essentially of a transmission device and a drive motor. The transmission device has a fixed guide tube with axis-parallel guide slots. Rotatably arranged coaxially in this guide tube is a control tube which is held by a ball bearing. This control tube has curved slots, the path of which differs from that of the guide slots. The curved slots and the guide slots have bolts passing through them in the operating position which are vertically displaceable by means of a spindle drive arranged coaxially in the control tube. In the event of a vertical displacement of the bolts, a rotation of the control tube occurs according to the relative curved path of the curved slots in relation to the guide slots. This rotary movement is transmitted outwards via a slip coupling and a rotary cover to a connecting flange for the door. The spindle is mounted rotatably within the control tube and is driven by the motor.

Title: Two-chamber barrier tube for contaminated stretches of water
Inventor: PRUSCINI BRUNO
IPC: E02B15/04
Filed: 1981-08-25
Abstract: The invention relates to a plastic or elastomeric barrier tube which is intended for collecting and holding off floatable, liquid or solid substances which contaminate stretches of water. On account of their light weight, known barrier tubes float up in moving water so that the barrier is breached. In the two-chamber barrier tube according to the invention, this disadvantage is avoided by flooding a chamber designed to be smaller in relation to the second chamber. The filled chamber sinks due to the greater weight and the total buoyancy is reduced so that a barrier is reliably achieved. The second chamber can be arranged inside the first chamber in a circular or elliptical shape and outside the air-filled, supporting chamber by a welded joint, for example of a flat tube, in the longitudinal direction. Furthermore, the tube can be provided with fastening lugs for attaching further weighting materials.
