Title: Car licence plate security system - includes holder with sharp projections defacing plate on disassembly
Inventor: SCHENK ALBERT
IPC: B60R13/10
Filed: 1978-11-30
Abstract: The arrangement is intended for securing the licence plate (5) of a motor car so that it is defaced on disassembly.

Title: Gasification of fluids esp. oxygenation of activating tank - by injecting air-sewage mixture into propeller pump suction
Inventor: SAMEIDER NORBERT
IPC: B01F7/02
Filed: 1978-12-05
Abstract: The fluid-gas-mixt. projection by an injector nozzle is guided to the suction section of a large propeller pump, in a process for delivering atmospheric oxygne, oxygen-enriched air or pure oxygen into fluids, and esp. into the activating tanks of clarifying plants with a predominantly horizontal flow. Used for the operation of sewage purifying plants in which the delivery of oxygen and the rotation of the contents of the tank are separates from each other. The arrangement ensures that the delivery from the injector is fed into the suction zone of the propeller pump(s), so that the water with an excessive amt. of oxygen is brought immediately into intimate contact with the water which is deficient in oxygen. This method achieves an efficiency of utilisation of the oxygen equal almost to 100%. The size of the injector nozzles is chosen so that stoppage by fibrous matter, etc. is not possible.

Title: Monitoring signal generation without using electrical power - by braking of measurement wheel coupled to pneumatically-driven wheel
Inventor: HERRMANN WOLFGANG
IPC: G01P13/00
Filed: 1979-08-18
Abstract: A device producing a monitoring signal, esp. for measuring the level in a container, has a measurement wheel on a driven shaft. The wheel rotation is braked or stopped when a given monitored condition is attained. It is suitable for use in explosive media at low cost and does not require the use of electrical energy. A drive wheel rotated by compressed air is mounted on a lever arm which pivots about the measurement wheel shaft. The measurement and drive wheel shafts are coupled via a gear train. The cross-section of a monitoring tube supplying the compressed air is varied according to the degree by which the lever arm is pivoted. The compressed air monitor tube outlet projects towards a deflection plate attached to the lever arm. Lever tilt during braking opposes a gear countering moment produced by an adjustable spring.

Title: Twisting spindle threading - has lower injector and centering mechanism for simple threading through yarn brake assembly
Inventor: HEMALA ZDENEK
IPC: D01H13/10
Filed: 1979-09-25
Abstract: There is an injector below the outlet end of the brake unit in the yarn brake of the two-for-one twisting spindle. The suction side of the injector is at the outlet side of the brake unit and the blowing side is at the spindle tube. There is at least one eccentrically aligned channel in the yarn brake leading to the injector, opening at a yarn entry surface of the yarn brake. There is a sleeve with a longitudinal slit at the coupling head, with a sealing surface acting with the end face to open at a feed for the compressed air. There is a supporting edge for the downward pressure of the axially sliding part of the yarn brake. The inlet tube is centered at the longitudinal slit's suction opening to give the threading position for the coupling head with the yarn inlet. Design gives a compact mechanism for the pneumatic threading of yarn into a two-for-one twisting spindle, which is easily mounted to the unit, and which allows the yarn to be threaded without difficulty through the brake unit.

Title: Heat-pump or energy management system - uses energy recovered from environment to drive heat pump by turbine
Inventor: BUTENUTH HELLMUTH
IPC: F25B27/00
Filed: 1980-01-16
Abstract: The heat-pump system recovers heat energy from the environment or waste heat. It uses a pump which is driven by a steam-expansion machine or turbine. The energy so obtained, in the form a refrigerating medium pumped up to vapour pressure and higher temp, is not used solely for the provision of hot water or other heating, but also to provide the mechanical energy to drive the heat pump. This is done by piston-type expansion machine or a turbine incorporated in the refrigerating medium circuit.

Patent DE-3043521-A1 (DE)
Title: Digital processing of document scan - uses nonlinearly encoded digital signal to give image-improving weighting
Inventor: BESTENREINER FRIEDRICH DR
IPC: H04N1/40
Filed: 1980-11-18
Abstract: Electronic picture or negative scanning and recording equipment uses an opto-electronic scanner and digital processing of the signal. The positive or negative original is illuminated and scanned to produce a signal for the a-d conversion stage comprising a signal shaper and a-d converter. The signal shaping enables fewer equal quantum step analysis to be carried out in later stages instead of using more nonlinear encoding stages. The signal processing stage comprises a store, digital equaliser and the evaluation processing stage. D-A conversion precedes amplification and then a laser light source is modulated to record the image. The quantum steps are divided into a number of stages between a min. and max. density so that the signal shaping and equal step encoding provides a combined non-linear, subjectively-designed result according to the given mathematical expressions.
