Title: Hosiery knitting frame programme control - changes slow to fast needle cylinder speed by programme cam drum
Inventor: BILLI GIORGIO
IPC: D04B15/99
Filed: 1973-07-27
Abstract: An electronic programme control system for a hosiery knitting frame produces a signal by a generator in synchronism with a needle cylinder for a digital counter and binary-coded decimal to decimal decoders. Coincidence gates receive their input from a cylinder cycle programmer and a program disc. The cam drum lead and the contact arm motion are controlled by a circuit. The needle cylinder speed is governed by a programmer and the drive motor for the needle cylinder by a speed control. A resetting unit returns the counter to zero. Thus it is possible to modify a programme more rapidly. The control responds more quickly and is less complicated than mechanical controls.

Title: Electrical line on semi-conductive substrate - has adjustable characteristic impedance, attenuation and phase by application of DC-voltage
Inventor: RABUS WERNER DR ING
IPC: H01L21/285
Filed: 1973-10-26
Abstract: The electrical line on semiconductive substrate has two or more separate metallic conductor strips and is characterised by that at least one of the metal strips forms with the semiconductive substrate to a metal semiconductor barrier contact. One conductor strip adjacent to the metal strip has with the semiconductive substrate an ohmic resistance. The semiconductive substrate may consits of a doped monocrystal part with high mobility carriers, of a doped gallium arsenide monocrystal part or of n-doped Si-monocrystal with a conductivity between 10-1 and 103 (ohm cm)-1. The semiconductive substrate may also be epitactic semi-conductor material. The semiconductor surface has an insulating passivation layer which during the manufacturing process of the line is etched away where the conductor strip is placed. the distance between a conductor strip forming a barrier contact and a conductor strip with an ohmic contact is a multiple of the width of the barrier layer free from movable charge bearing carriers directly underneath the conductor strip. the width of the barrier layer below the strip is influenced by an applied d-c bia s between conductors. The arrangement permits due to the voltage dependent capacity layer to vary by d-c biassing the characteristic impedance, attenuation, phase of the line.

Title: Fluid pressure seal for rotating shaft - uses C-section member to increase pressure tightness with increasing fluid pressure
Inventor: RUF MAX
IPC: F16J15/32
Filed: 1974-03-27
Abstract: The shaft has a flange and rotates in the housing containing fluid at pressure tending to flow outwards in the direction of the arrow. The sealing rin body has a L-shaped cross section and supports a C section flexible sealing member. As the working pressure increases the C section tends to deform and exert an increasing outward pressure on the surface of the bore thus increasing the pressure tightness of the seal. A spring ring maintains the axial pressure on the sliding sealing strip which is pressed against the flange. To improve resistance to centrifugal force, an alternative design allows the C section to seal on its inner diameter.

Title: Replacing damaged hammers in car-breaker's hammer mill - interposer rod pushes out temporarily interposed rod
Inventor: LENZ HANS RICHARD
IPC: B02C13/28
Filed: 1974-08-06
Abstract: Replacement of a hammer (1) involves pushing out the axle it sits on, until the hammer is freed, changing the hammer and replacing the axle. The piston works in several short strokes, the hydraulic cylinder being moved forward between strokes. The axle is pushed right out by a separate interposed rod (not the piston rod directly) and then brought round and used to push out the temporarily interposed rod. Thus the cylinder is not required to pull, only to push. This allows the use of a smaller cylinder which also takes a shorter stroke. A cable and pulley is used to pull the axle through when necessary.
