Abstract: 2-Imidazolines of formula (I) (where R1, R2 and R3 are aliphatic, cycloaliphatic, araliphatic, or aromatic residues, R2 and R3 can also be H, and R1 can also be a gp. of formula (Ia) (in which R4 is an aliphatic residue), e.g. 2-methyl-2-imidazoline or 1,4-di(2-imidazolin-2-yl-)-butane, are prepd. by reacting 1,2-diamines of formula H2N-CH2-CHR3-NHR2 (II) with nitriles of formula R5-CN (III) (where R5 is R1 or a gp. -R4-CN) in the presence of polysulphides of formula Z2-Sx (IV) (where Z is an ammonium gp. or an alkali atom and x is 2,3,4 or 5). (I) are useful as starting materials for dyestuffs, plant protection agents and pharmaceuticals. They are also useful as catalysts for polymn. reactions and polycondensations. They may be converted into the corresp. imidazoles by dehydrogenation on aluminium/zinc oxide catalysts. In comparison with known procedures, the new process is simpler and more economical, and gives (I) in improved yields and purity. Reaction temps. are lower than when no catalyst is used.

Title: Liquid metal switch with two electrodes - has working fluid driven electrodynamically to bridge two fixed contacts
Inventor: MAREK ALOIS DR
IPC: H01H29/00
Filed: 1975-04-07
Abstract: The liquid metal switch has mercury, an alkali metal, an alloy of mercury and an alkali metal or a solution of an alkali metal in ammonia as a working liquid driven electrodynamically to bridge two fixed contacts. The two electrodes (101, 102) project into an initially empty chamber above the liquid metal flow channel, i.e. above a reservoir (32) connected to this channel. The liquid metal is acted on by two sets of permanent magnets or electromagnets and is caused to flow round the channel such that the reservoir empties and the switching chamber containing the electrodes fills thereby connecting the electrodes.

Title: Automatic transportation system routing control - with central controller and registers added to existing equipment
Inventor: DOBLER KARL-ULRICH DR ING
IPC: B61L27/04
Filed: 1975-04-16
Abstract: An arrangement for mode determination and variation in an automatic transportation system uses a control register (BR1) and a destination register (FZR1) in each vehicle (k). In the operations centre (DZ) are registers for control (BR2), destination (FZR), and position (SR), and a comparator (VG) for each vehicle. At the start of each journey the operations centre determines the operating mode and destination and stores them in corresp. registers (BR2, FZR), from which the information is sent to the vehicle registers (BR1, FZR1). The vehicle periodically transmits its position to the position register (SR), whose contents are compared with the destination by the comparator (VG). At the destination the registers are reset. With the exception of the registers, the system consists of devices contained in existing equipment.

Title: Liq. gasifier with rotor and surrounding diffusor - has steps in diffusor walls to break down large gas bubbles
Inventor: BRAUN ERNST DIPL ING
IPC: C02F3/20
Filed: 1975-05-16
Abstract: An appts. for gasifying liqs. comprises an impeller or rotor surrounded by a stationary diffusor having an increasing cross-sectional area from inlet to outlet, which is at the periphery of the diffusor; gas is introduced at the outlet side of the rotor. The flow cross-section of the diffusor has >=1 stepped increase, esp. formed by a surface branching out perpendicularly to the flow direction. The total area across each stage is pref. approx. uniform, i.e. the decrease in thickness compensates the increase in circumference; there is thus a sudden increase at each step. Alternatively, there is a steady decrease within each stage, followed by an increase at the step. The appts. is used for submerged gasifiers or aerators. The tendency of large bubbles to flow counter to the increase in pressure, i.e. inwards through the diffusor, is counteracted by the turbulence created at the steps; this breaks up the bubbles and gives a finer distribution.
Patent DE-2522911-A1 (DE)
Title: Dowel plugs and strip securing wooden beam to uprights - is of galvanised steel with round dowels and self tapping screw holes

Title: Impeller-type propellor for ships - has elastic membrane to separate oil filled hollow sections for pressure compensation
Inventor: SCHMATOK VIKTOR P
IPC: B63H23/32
Filed: 1975-08-08
Abstract: The impeller-type propellor has a stator, and a rotor, which is revolvable about an axis, at right angles to the stator plane. Hollow sections in the rotor and stator may be filled with oil, and are connected with a member, to allow a balance between the pressure in the hollow sections and the hydrostatic external pressure. The member consists of a flexible elastic membrane (8), which can hermetically seal and separate the oil-filled hollow sections (a, b) from the surroundings. This allow the use of the propellor in deep sea vehicles. The membrane is fastened in one of the housing sections (1, 2) of the propellors.

Title: High torque planetary gear set - has different numbers of internal teeth on concentric ring gears meshing with eccentric planetary gear
Inventor: FICKELSCHER KURT G
IPC: F16H1/32

The teeth are triangular in form and mesh with an eccentric drive gear with external teeth of similar shape and pitch. A cam drives the planetary gear. The virtual teeth may be formed on an external surface and driven from outside by a surrounding ring gear with internal teeth. All teeth are used to transmit the torque, with the exception of the difference in number of teeth between the two gears forming virtual teeth.

Title: Shoe sole gluing press - is started by switch operated by upper when inserted in mounting
Inventor: FUNCK HERBERT DR ING
IPC: A43D25/07
Filed: 1975-10-31
Abstract: The press has a pressure-operated press cushion with a highly elastic membrane securing the sole to the upper fitted over a last in a mounting. The mounting (3) has a switch (28, 29) automatically operated on insertion of the upper (5), and starting up the drive (19) moving shoe mounting and cushion (10) together.

Title: Fabric cladding control process - uses a continuous measurement of electrical conductivity to regulate the cladding action
Inventor: REIMERS HARALD DIPL CHEM DR
IPC: D06N3/00
Filed: 1975-11-03
Abstract: Cladding of a continuous moving fabric with a layer of foamed or unfoamed watery plastic and/or rubber dispersion is claimed. When the cladding layer has been applied the electrical conductivity of the cladding mass is measured continuously during the next phase of the treatment process. The system provides a constant quality control of the cladding process, giving a continuous adjustment of the cladding to prevent faulty fabrics being developed, and to prevent unnecessarily long dwell times in the drier which would impose high temp. on the mass.

Title: Line thinning system for character recognition - simplifies recognition by subsequent devices and also increases character putput
Inventor: KRIEN REINHARD
IPC: G06V30/168
Filed: 1975-11-12
Abstract: Each character point is moved to a central position for a decision whether or not it is needed for the refined character. The refined structure is fed back to a logic network, compared with the original structure and the decision is then made as to whether to retain the given character point. Pref. a shift register stores the original character, and the logic network is in series with a second shift register. The logic network decides from given locations in the two shift registers corresponding to the surroundings of a selected position in the character pattern whether the selected position retains the binary value "1".

Title: Rack for laundered trousers - has stretcher device with rollers preventing shrinkage of wet trousers
Inventor: TIGGES FRIEDHELM
IPC: A47G25/68
Filed: 1976-08-09
Abstract: The trouser rack comprises two stretcher devices (A1, A2) so that when placing wet trousers on the rack they can be stretched to avoid any shrinkage. The rack also includes two rollers (B1, B2) of which one (B2) has an off-centre bore so as to move eccentrically on a shaft (X). By the interaction of these rollers the stretching devices increase the clamping effect on the garment in proportion to the traction to which the latter is exposed so that the material cannot slide out during the stretching process. The rollers (B2) can be divided into several sections of equal or unequal length so as to move eccentrically on the same shaft X independently of each other in order to adapt to any unevenness.
