Patent DE-4340871-C1 (DE)
Title: Method for determining the degree of icing of a refrigerant (refrigeration) evaporator for refrigeration (refrigerating, cooling) plants
Inventor: LUDWIG MATTHIAS DIPL PHYS
IPC: G01M7/08
Filed: 1993-12-01
Granted: 1995-04-27
Abstract: The determination of the state of icing of evaporators which are located in refrigeration (cooling) devices, heat pumps etc. is attended by difficulties. The novel method is intended to enable the current degree of icing of an evaporator to be determined reliably without the use of thermodynamic measured quantities. An evaporator is excited to perform natural vibrations (oscillations) by means of impulsive excitation. An accelerometer which is mounted on the evaporator records the vibration. The signal is digitised and converted by a computer with the aid of a rapid Fourier transform into a discrete frequency spectrum. The degree of icing of the evaporator is determined by comparison with previously recorded reference spectra. The method is suitable for determining the degree of icing of evaporators, in order to determine the thawing instant and in order to monitor the status of a continuing thaw.

Title: Magnetic grip tracked vehicle
Inventor: METZNER PETER
IPC: B63B59/10
Filed: 1993-12-23
Granted: 1995-07-27
Abstract: The remote control tracked vehicle grips the steel wall via permanent magnets embedded in the track elements (7) and moves working tools over the steel surface. The track elements each have a single rear spur which is pulled through an outer groove of a flexible central frame (6) between the drive wheel (3) and the tension control wheel (5). The two wheels are similarly grooved and the tension wheel is mounted on tension arms (17) which adjust the track tension and which can be moved laterally by a servo drive (14,15,16) to steer the vehicle. The vehicle is made of non ferrous material, e.g. aluminium and plastics while the central frame is made of non magnetic stainless steel. The middle of the vehicle has two lateral support wheels (18) which are non steered.

Title: Braille=forming machine on endless elastic tape
Inventor: MORELL BERNHARD
IPC: G09B21/02
Filed: 1994-08-31
Granted: 1996-01-04
Abstract: The cuts are formed in a regular pattern in the tape, and they can be inclined to a plane at right angles to the tape surface. The lugs can be movable between a first stable retracted position in which they cannot be felt and a second protruding position forming the characters. A punch is used to bring the lugs into the protruding position. The punch can be solenoid-operated. An indexing hole can be provided in the tape at each gap between adjacent cuts. This is detected by a photoelectric cell. The tape can be stretched in the lengthwise direction, causing the lugs to spring back into the retracted position.

Abstract: FIELD: medicine. SUBSTANCE: method involves the steps of: placing a test object to be mixed into a cylindrical cuvette made of optically transparent material and a mixing member made of magnetic material as well; producing a rotating magnetic field with the aid of four flat pair-wise connected coils coupled to sinusoidal current sources with a phase shift of 90 degrees, the pole-pieces being uniformly distributed along the circumference to concentrate rotating magnetic field; placing the cuvette with the test object into a round opening defined by the flat pole-pieces such that upper level of liquid in the cuvette coincides with the magnetic field plane. The magnetic field holds the mixing member on surface level and simultaneously drives it into rotation thus mixing liquid. The coil magnetic cores are oriented in space such that measurement light flux passes through the test object through the cuvette center orthogonally to its axis without obstacles.
