Title: Paper strip tension regulating system - has brake to apply constant braking pressure, to each end of storage roll
Inventor: SCHUESSLER JEROME E
IPC: B65H23/06
Filed: 1976-06-28
Abstract: The system regulates the tension in a strip of paper to avoid distortion caused by uneven lengthwise tension over its width, as it is pulled off a storage roll. An even and constant braking pressure is applied to the opposite ends of the storage roll (12, 15) as this is unwound, the braking pressure being limited to a figure between 10 and 80 lbs (sq. in (0.7-5.6 kg/cm2). The braking pressure is kept at a constant low figure, to give the maximum lengthwise tension on the paper strip (12'). It can be such as to exert a torque of between 10 and 190 ft/lbs (1.3-24.7kgm) at each end of the storage roll.

Title: Optical light guide fibre bundles - produced in concentric nozzles of concentric crucibles by centring cone forming bundles for coiling
Inventor: GRABMAIER JOSEF DIPL PHYS DR R
IPC: C03C25/104
Filed: 1976-07-09
Abstract: Optical light guide fibres are drawn from an inner crucible for the core material and an outer crucible for the sheath material, both with a pattern of coaxial concentric nozzles in their bottom plates. A system of stoppers can be used to close the nozzles from below. Lopping knives sever the fibres from the stoppers before a protective coating is applied and the fibres are grouped to a bundle in a centring cone ready for winding into coils. Sheathed optical light guide fibres can thus be produced in bundles, ready for installation.

Title: Fault detection in automatic gearboxes - includes testing vehicle on rolling road and recording conditions under which gear change occurs
Inventor: LEDERHAAS JOSEF
IPC: G01M13/02
Filed: 1976-12-11
Abstract: A method of detecting faults in automatic gearboxes in motor vehicles includes measuring the gear box switch times when changing gear. This is carried out by monitoring rotary speeds and comparing the results against those from a known good unit. The testing takes place on a rolling road with a large moment of inertia. Engine rotary speed is measured from a transmitter connected to the distributor via a gear wheel. Gear box rotary speed is measured at the box input and output using built in transmitters connected via slip rings and gear wheels. Transmitter outputs are passed to a single channel linear pen recorder to give graphical presentation of rotary speed with elapsed time.

Title: Laser system for anti-aircraft or anti-missile defence - uses start laser and plasma injection laser coupled together in coaxial unit of specified length
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/09
Filed: 1977-07-14
Abstract: The laser system preferably uses a plasma laser arrangement which is simultaneously pumped with photons, electrons, neutrons and fission alpha particles. The system contains a start laser with uranium reactor. The two laser types are coupled in a coaxial unit of specified constructional length. The start laser ignites via an injector a three layer fuel pill in the operating laser. subsequently the system uses reverse ignition process for delivering the next ignition pulse by transmitting the amplified output via mirrors and prisms, serving as optical branches and energy dividers. This starting pulse has sufficient energy to ignite the injected fuel pills. Thus the three-layer pill is necessary for the start only.

Title: A=D converter with integrator - has integration time made multiple of pulse period from noise signal discriminator
Inventor: BAYATI ABUTORAB DR
IPC: H03M1/00
Filed: 1977-07-21
Abstract: The A/D converter integrates the analog input over a given time and contains a discriminator to which ac noise signals superimposed on the analog input signal are passed. The discriminator produces a pulse when the noise signal passes through zero and passes this pulse to a control unit. The latter releases the integrator for integrating for a time equal to an integral multiple of the period of the pulses from the discriminator. If the converter contains a voltage/frequency converter than its counter is released for connecting to a computer that divides the count reached by a given number.
Patent DE-2734564-A1 (DE)
Title: Comber waste collection - using a perforated suction drum to form noil(s) into a wadding for sliver formation
Inventor: HUESGES GERD
IPC: D01G21/00
Filed: 1977-07-30
Abstract: The mfr. of a yarn from noils uses suction to collect and compress the comber waste into a wadding. A suction drum is rotated along the rear side of a comber with a number of combing stations, with its mantle perforated in the combing zones. There are wadding deflectors at the perforated zones of the drum to pass the felting to a lower continuous conveyor, running parallel to the drum. The material passes through a silver formation section, and sliver monitor, with a control gearing, followed by paired drawing rollers. The material is formed into sliver by two powered rollers. The control gearing is connected to the lower roller of the drawing rollers. The perforated zones of the drum are connected to the combing rollers of the combing station by a conical channel tapering inwards. The transporter is a continuous belting action with rollers pressing the combings into a wadding. The process allows noils to be recovered and used to produce a yarn.
