Patent DE-2658889-A1 (DE)
Title: Solar heat collector with partitioned air chambers - has shortened lengthwise walls leaving chamber top undivided
Inventor: STORK ALOIS DIPL ING
IPC: F24S10/50
Filed: 1976-12-24
Abstract: The solar heat collector generates warmed air, having air chambers inclined to the horizontal with partitions and light-permeable cover plates, in which the air flowing in from the surroundings is heated and drawn off at the top via a buspipe. The lengthwise walls, which cross the continuous cross-walls and extend from bottom to top, are shortened, so that the undivided top transverse portion of the chamber forms the buspipe. The lengthwise walls are continuous, while the transverse ones have openings offset from each other. Thus the heated air flows through the chambers between adjacent lengthwise walls in a zigzag pattern.

Title: Fibre optics data transmission system - transmits information signals, and normalisation signals in gaps to give continuous transmission
Inventor: WITTENBURG JOACHIM ING GRAD
IPC: H04B10/60
Filed: 1977-02-19
Abstract: The system consists of a transmitter, a glass fibre transmission path and a receiver. A photosensitive component is used at the receiving end, converting optical into electric signals and applying the electrical signals to an amplifier, which in turn delivers amplified signals to a signal processing unit. So long as the transmitter and receiver correspond with each other, the transmitter continuously delivers signals, so that when no information signals are transmitted, balanced normalisation signals are transmitted. Two amplifiers (3, 4) may be used.

Inventor: VOX ANTON J
IPC: G21F9/28
Filed: 1977-10-20
Abstract: A method of transporting and storing substances or objects which emit radioactive radiation consists of first placing the objects in a storage container then filling this container with a molten salt mixt. to embed the articles and then cooling the salt mixture to solidify it around the articles. After transportation to destination, the salt mixt. can then be melted again to recover the articles for use. Pref. the temp. of the molten salt mixt. when poured into the container is >=98 degrees C. A salt mixt. having >=41% salt content is pref. used. More specifically, it may contain glass fibre or other insulating material. Typically, used for transporting new fuel elements to a reactor or used fuel elements away from a reactor. Also for transporting any other radioactive substances. Used fuel elements can immediately be embedded in a salt block which absorbs a given amount of heat and enables the elements to be removed immediately from the reactor area without temporary storage. The block also acts as shock resistant surround.

Several parallel conveyor belts may be used in a mass prodn. plant. Economic mass prodn. easily adapted to different types of pottery, crockery, etc.
Patent DE-2826645-A1 (DE)
Inventor: KRUEGER GUSTAV DIPL PHYS DR
IPC: G01R1/073
Filed: 1978-06-19
Abstract: A multiplicity of sleeves (1) are installed parallel and side by side in an adaptor plate (2). At one end, each sleeve has a contact piston (4) which is inserted such that it can move longitudinally and projects beyond the sleeve end. This piston is supported via a helical spring (11) on a connecting pin (8) to which electrical wires are soldered for passing on a test current. The solder points (10) are arranged offset over the length of the connecting pins, the length of each connecting pin being dimensioned to be larger than the total length extent of all the solder points. In consequence, the distance between the contact pistons can be kept as small as possible. The connecting pins rest on a stop plate (9) which allows removal and installation of the adaptor plate without displacing the contact pistons. The contact device is used for measurement and test purposes. <IMAGE>

Title: Vibrator driven by two sync. three=phase motors - can change out-of-balance force by varying phase lag of one motor
Inventor: REDMER RUDI
IPC: B06B1/16
Filed: 1978-10-02
Abstract: A vibrator is constructed from two synchronous, three-phase motors each driving an out-of-balance rotor. When the phase lag of each motor is the same, the out-of-balance force of one motor cancels the out-of-balance force of the other. By changing the phase lag of one of the motors the magnitude of the resultant out-of-balance force can be changed. If the motors rotate in the same direction the vibration is circular, but if they rotate in opposite direction the vibration is linear.

Title: Analog=digital converter which employs comparison and subtraction - has measuring units comparing inputs with reference and uses standard parameters which use set of golden numbers
Inventor: STACHOV ALEKSEI PETROVITSCH
IPC: H03M1/00
Filed: 1978-12-19
Abstract: The A/D converter has a device to select the conversion error code whose inputs are connected to the outputs of the measuring units and whose outputs act as the outputs for reading off the conversion error code. The magnitude of the standard parameter (=reference) with which the analog parameter is compared is proportional to the weighting of the corresponding code place in the code number. The magnitude of this standard parameter in each measuring unit is proportional to the corresponding Fibonacci p-number or the corresponding power of 'golden' p proportions which is a positive root of the equation xp+1 - xp-1- =0.
