Title: Non:slip sleeve for bottom end of walking stick - has retractable spring: loaded steel spike actuated by press button and penetrating rubber base
Inventor: KLOSSEK WILLI
IPC: A45B9/04
Filed: 1975-11-05
Abstract: The non-slip device for the bottom end of walking stick or crutch comprises a sleeve, with a cone, a spring, and a steel spike which can be extended for icy conditions or retracted for normal conditions. In an example, the sleeve is installed by shortening a conventional stick or cructh by about 90 mm and fitting it onto the lower end of the stick. By actuating side knobs by applying downward pressure, the steel spike can be extended: the spike passes outwards through the rubber base and engages firmly e.g. in ice. For normal ground conditions, the knobs are compressed, and the spike springs back into an inoperative position in the sleeve by spring force, so that the stick rests on rubber base.

Title: Skirt or trouser hanger with spring arms - has one arm looped back to join and support hook for greater stability
Inventor: LIEBSCHER JOHANNES
IPC: A47G25/62
Filed: 1975-12-12
Abstract: The trouser or skirt hanger comprises a basic straight rod element (11) which supports the two resilient tension members (14') wherein a second angled rod element (12) which is moulded onto one end of the first rod to form the hanger hook (13) is in addition connected in supporting manner to the first rod at the end remote from the join to the hook. Thus even if the rod elements (11,12) are comparatively thin the rod element supporting the tension elements and the tension spring (15) cannot bend downwards so that the strength and stability of the hanger is increased. The second rod (12) which forms the hook can in fact be connected to the first rod beneath the hook in which case this supporting area is formed by a U-shaped bend in the second rod.

Title: Process control monitoring data gathering circuit - transfers randomly occurring binary data from several sources to central processor
Inventor: SCHMIDT EBERHARD DIPL ING
IPC: G06F19/00
Filed: 1976-01-02
Abstract: A circuit for numerically controlled input of binary data gives situation variations in technical processes into data processing units, esp. in automatic railway shunting yard systems. It accommodates randomly occurring binary data from several similar recording units in the system and transfers the data in suitable form to the system central processing unit.

Received data is fed via resettable flip-flops to input registers which are cyclically accessed. The data are identified as to origin and compared with the relevant reference data from the status register.

Title: Anti-fouling device for window below water - uses waves from ultrasonic generator causing vibration of glass surface
Inventor: KOEHLER WINFRIED DR ING
IPC: B63B59/04
Filed: 1976-04-17
Abstract: The anti-fouling device for optically transparent bodies in water, esp. seawater uses ultrasonic with transmission or emission of the vibrations by the body surface. The window in a sensor unit is faced by an identical one backed by a reflector in a water-permeable frame fixed to the instrument. Waves from an ultrasonic generator of 20-100 KHz; emitting for 1-120 secs. at intervals of 0.5-24 hrs, are symmetrically divided by a reflector in the bottom of the frame midway between the bodies and reflected onto them. This causes evenly distributed vibration of the surfaces, preventing any growth without affecting the passage of light waves. The bodies are pref. of cavitation resistant material, e.g. sapphire.

Title: Damper for hydraulic chain tensioner - has nitrogen filled rubber bag secured to one side of hydraulic piston
Inventor: MENKHOFF KARLHEINZ
IPC: F16H7/08
Filed: 1977-05-05
Abstract: The hydraulic chain tensioner has a rubber bag secured to one side of a piston and filled to a given pressure with nitrogen. On occurance of a load and consequent movement of the piston, oil at the other side of the piston passes through a passage in the head to the side having the bag. The oil compresses the bag. When the load ceases and the piston returns, the expanding bag returns the oil through a check valve in the head to the one side of the piston. This provides a uniform resistance over the whole piston travel and damps the return of the piston.
