Title: Pneumatic system rotating joint for multiple pressure lines in printing machine - uses coupling piston with flat mating face and concentric coupling slots of differing radii
Inventor: DIETRICH BERND
IPC: B41F21/10
Filed: 1992-03-23
Abstract: The pneumatic rotating joint connects pressurised air lines from the static (D) to a rotating drum or cylinder (1). The coupling consists of a housing (4) fixed on a sidewall (3). A connecting piston (5) is located radially by a peg (6) but is free to move axially. Air lines (10,11) connect to different radii on the face of piston (5).

Title: Hand operated welder for thermoplastics - comprises handle with heating cartridge and switch which reduces current to lower level after time delay
Inventor: WETZKA ROLF
IPC: B29C65/10
Filed: 1992-05-04
Abstract: Hot air gun has a handle with an electric cartridge for heating an air stream fed in via a tube. Heated air is directed by a nozzle onto the welding area. Manually operated switch on the handle controls current supply to the heating cartridge.

Current redn. after a given delay, approx. 3 mins., is not reduced to zero, but maintained at an average value below the working temp.. An air flow sensor in the form of a flap is located in the air feed pipe and is connected to a microswitch. When the air flow fails without a time delay or completely, current to the heater cartridge is switched off to prevent overheating. Heater cartridge is enclosed by a perforated plate (8) to prevent contact by hand. USE/ADVANTAGE - For hand welding thermoplastics materials. Uses less energy during breaks in operation.

Patent DE-4304247-A1 (DE)
Title: Liquid cooling system for an internal combustion engine
Inventor: STEINBERG PETER DR
IPC: F01P3/22
Filed: 1993-02-12
Abstract: In order to reduce the fuel consumption and the HC emission in the partial load range and to curtail the warm air phase after a cold start, it is proposed, in an internal combustion engine with a liquid cooling system, to provide a condensation chamber, which forms a circuit with the coolant pump and the radiator, in or directly on the cylinder head at the geodetic highest point of the cooling circuit. Only static coolant, which therefore has a tendency to more or less intense formation of vapour locks depending on the operating point, is present in the engine itself. These vapour locks are liquified in the condensation chamber.
Patent DE-4305799-A1 (DE)
Title: Method for checking reusable containers
Inventor: HEIDRICH KARL HERMANN DR
IPC: G01N1/22
Filed: 1993-02-25
Abstract: The invention relates to a method for checking reusable containers for their contents, in particular for the detection of contaminations. For this purpose, it is known to feed the containers to be examined in a closed row to a rotating machine which has a multiplicity of sample removing tubes on the rotor periphery, above the container stands. After receiving the containers, the tubes are lowered into the latter, whereupon a corresponding partial stream of the air located therein is sucked up and fed to the analysis station. The expenditure in terms of machinery necessary for this, in particular for the insertion and withdrawal of the sample removing tube, is correspondingly high and prolongs the passage times. By means of the invention, a simplification is to be provided, trouble-free separation of the respective samples to be taken one after the other being intended to be given. According to the invention, this object is achieved in that the sample removal is carried out in the detector space of an analyser by means of valve-less cross-flow modulation of measuring gas and zero (blank) gas.
