Title: Circular knitter needle selector - has selection movement towards the curve of the needle cylinder for high working speeds
Inventor: CHLADEK OTAKAR DIPL ING
IPC: D04B15/78
Filed: 1989-08-29
Abstract: In the needle selection mechanism of a circular knitter, the moving components to operate the push rods are mounted to move towards the curve of the needle cylinder. The moving components are fitted to a grooved ring which is coupled to the needle cylinder through a kinematic cogwheel gearing so that the rotary speed of the ring is less, on its axis which similar to that of the needle cylinder. Selectors are fitted in the radial grooves to slide in the ring, with the selection units at their outer ends on the ring, and their opposite ends have butts at a rate of one butt for each selector. A sliding pressure cam is provided for each selector butt at the ring, in a vertical stack, and the selector butts of the push rods lie on a diagonal.

Title: Channel-cleaning device for clarifying tanks - in which forward motion of brush support system is used to cause brushes to rotate, thus eliminating need for separate brush drive motor
Inventor: GLASER BERND
IPC: B01D21/24
Filed: 1989-09-01
Abstract: The clarifying tank has a brush drive system and a brush support which can be moved along a discharge channel. The drive system comprises driving wheel which is pressed by a wt. or by a spring against a stationary member, and mechanism which couples the brush spindle to this driving wheel. If a spring is used, its other end may serve to press a wheel fixed to the brush spindle against the opposite side of the stationary member. These wheels may be toothed or may be turned by friction. The tank may be provided with a travelling surface-cleaning bridge, in which case one of the wheels of the bridge may serve as a driving wheel for the brushes. USE/ADVANTAGE - This invention is used in clarifying tanks intended for example for sewage treatment works, in which it is important to keep the outflow channel from the tank free of the build-up of deposits. The design of a rotating brush cleaning system is improved so that an electric motor drive and the associated equipment are no longer reqd.
Patent DE-3929252-A1 (DE)
Inventor: EBERT CLAUS
IPC: A47F5/08
Filed: 1989-09-02
Abstract: A securing plate with transverse T-shaped grooves for suspending tools, containers, objects and the like consists of at least two superimposed sections of extruded hard synthetic foam cut to length which can pivot intimately within each other at their folded overlapping longitudinal edges given a hooked or otherwise matching shape. These interlocking sections (16, 18) taper at the hook end or at the base of the shaped section and the curved outside at least of the matching shape (18) runs towards the rear of the plate at a sharp angle ( alpha ) which completes the angle which the main surfaces of the sections (14a, 14b) make together on engagement before pivoting to 90 DEG . This makes it possible to engage even long sections with inevitable distortion safely together.

Title: Wear resistant armouring for rolls - using rings with interlocking edge profile
Inventor: FISCHER-HELWIG FRANK
IPC: B30B3/00
Filed: 1990-05-29
Abstract: Wear resistant armouring for rolls for use e.g. in high pressure roll presses for milling granular materials, consisting of several wear resistant rings with interlocking edge profiles mounted on a support roll. Pref. the developed interlocking edge profile of the armouring rings may be of zig-zag (10 to 14) or sinusoidal wave form.

The input signals from each generator are supplied to photosensitive components and/or voltage dependent light emitting components of the members. The binary output signal as a current or voltage signal with a defined level starts (in)directly the operation of a device, which dangerous if inadvertently operated. To a second binary level of the output signal corresponds the rest state of the device. The transmitted signals are in such logic coupling that on interference of the light transmission all components remain on the rest level. USE/ADVANTAGE - For control and monitoring circuits for machines and industrial processes, simple design for high security on failure of respective components.

Title: Wear and overload signal system for charger hoists e.g. for concrete - activates warning signal or switches from drive system with overload or wear of carrying rope and prevents fall of hoist bucket
IPC: B66B7/10
Filed: 1991-01-23
Abstract: A second rope drum (8) turns in synchronism with the first known drum (5), on which a safety rope (9) is wound running in the same direction as the carrying rope (6). The safety rope runs parallel to the carrying rope across a second rope pulley (10) at the charger bucket (1) and is suspended at its free end to a spring loaded suspension bolt (11) or is fixed directly at the charger. The safety rope, in conjunction with the spring coupled at its free end, has a softer spring characteristic than the carrying rope, or the safety rope in conjunction with a spring mounted deflection has a softer spring characteristic than the carrying rope, which is fitted outside the charger bucket travel range with at least one sensor. The sensor monitors the movements of the safety rope or the spring for unpermitted wear, namely, with overloading of the load rope activates a warning signal or the switching off of the drive. ADVANTAGE - Protects against overload or wear of rope and overcomes disadvantages by also preventing drop of bucket, tipping or sticking fast, when bucket is travelling upwards.
