Title: Exothermic catalytic reaction - with removal of heat in indirect heat exchange in a series of zones
Inventor: SCHNEIDER HELMUT DIPL ING
IPC: B01J8/04
Filed: 1975-02-03
Abstract: In carrying out exothermic catalytic reactions in a single or multi-zone catalyst system (i) the feed medium is subdivided into >=2 part-streams, the first of which flows through th whole length of the catalyst system and the remaining part-stream being supplied to the system at a number of different locations which can be selected according to special points of view and (ii) the heat of reaction is simultaneously removed at least in part by indirect heat exchange with a cooling medium within the catalyst system. Advantageously, the process is applied to the reaction of CO and H2 in the presence of H2O to give a methane-rich gas mixt. Enables heat to be removed in zones of exothermic reaction and reintroduced in zones of endothermic reaction without contaminating the prod. with the treat transfer medium.

Title: Nondestructive simultaneous determn of total donor and acceptor - esp phosphorus and boron concn in high-ohmic monocrystalline silicon
Inventor: KOLBESEN BERND DR
IPC: G01N21/3563
Filed: 1975-02-27
Abstract: The nondestructive simultaneous determn. of total concn. of donors and acceptors, esp. P and B in high-ohmic, monocrystalline Si is achieved by irradiating the Si sample at low temps. in the T nearly equals 15 degrees K region with light contg. wavelengths stimulating the valency band-conducting band transition and determining the observed IR bands of the donors and acceptors quantitatively. The method allows the degree of compensation to be determined for high-ohmic Si starting material for the prodn. of semiconductors.

Title: Control element operating states monitor - compares data derived from input signals with reference data
Inventor: YAMAUCHI NOBUHARU
IPC: G05B19/048
Filed: 1975-03-27
Abstract: The invention provides an instrument for monitoring the operating states of a control element by deriving data from input signals relating to it and comparing these with reference data before feeding new reference data to a store. Data are generated from input signals by means of an impulse generator counting circuits and gates and fed to a buffer stores. From this store they are passed by a control circuit to another control circuit where they are combined with data from a reference data store. A symbol generator then generates symbols for display on a screen depending on the combined data.

Title: Cord ply folding apparatus - for tyre mfr. using pivotable segments on a ring coaxial with tyre building drum
Inventor: NAEDLER HEINRICH
IPC: B29D30/26
Filed: 1975-04-15
Abstract: In an apparatus for manufacturing a folded ply for use in a vehicle pneumatic tyre, particularly a tyre belt, by wrapping at least one edge along a circular fold line of a cord embedded in a rubber mixture and wound on a cylindrical drum of reducible diameter with at least one inflatable bellows laying laterally for wrapping, a ring displaceable coaxially to the drum and surrounding but spaced from this has a support edge of reducible diameter which can be pressed on the wound on cord circularly along the fold line. Advantageously the support edge is constructed from a series of adjacent situated claw-type segment pivoted on the ring with their free ends on the fold line. Overcomes the difficulty that in the case of cords of high stiffness, e.g. thick strand steel cord cannot be folded accurately with non-reinforced inflatable bellows.

Title: DC motor field windings - rectangular section windings are bound together using prepregnated insulating material
Inventor: HUEBLER KARL-HEINZ
IPC: H02K3/18
Filed: 1975-05-31
Abstract: Flat bar conductors are laid in flat concentric coils of generally rectangular shape. A number of such coils are laid over each other with interleaved insulation. Around the limbs of the resulting stack of coils are wound at intervals a number of self adhesive bands. The plane of the coils are distorted to conform to the curve define by the machine radius, and under pressure and/or heat the insulating layer softens and binds the structure into a solid unit. The invention enables the advantages of a round machine yoke and the good heat removal of rectangular windings to be combined without a noticeable increase in preparation requirements.
