Patent DE-2321391-A1 (DE)
Title: Multicolour ornamental wax candle prodn - on mould table tiltable in all directions between pourings
Inventor: KOCH PETER
IPC: C11C5/02
Filed: 1973-04-27
Abstract: Ornamental wax candles of multicoloured patterns at different angles are produced by pouring in turn wax of different colour into moulds fixed to a table. The table can be swivelled through various angles between each pouring. The table tops can be hinged and tilted through an axis at right angles to the first. This saves producing the candles singly by individual tilting of each mould. It combines a mass prodn with a certain freedom of individual pattern for the candles.

Title: Regeneration of coked catalyst from catalytic cracking - by fluidising with oxygen-contg gas
Inventor: CASTAGNOS JUN LEONCE FRANCIS
IPC: B01J38/36
Filed: 1973-06-16
Abstract: In a continuous fluid catalystic cracking process, the coke-contaminated catalyst is passed continuously to a regeneration zone where it is fluidised with a rising stream of O2-contg. gas to form a dense-phase catalytic bed and a dilute catalyst phase, the temp. and regeneration gas flow rate being sufficient to convert practically all the coke into CO2. The dense-phase temp. is pref. 690.6-816.6 degrees C and the dilute-phase temp. is pref. 815.6 degrees C after burning in the dilute phase pref. being practically zero. The flow rate of regeneration gas is pref. adjusted to give an effluent gas contg. >1 vol. % O2. Regenerated catalysts contg. 0-0.1 wt. % coke can be obtained, and the effluent gas contains 0-0.1% CO.

Title: Emergency support for levitated vehicle tracks - has a number of sliding shoes with bristles or thin plates frozen together by ice
Inventor: FICHT REINHOLD
IPC: B61F11/00
Filed: 1973-07-25
Abstract: This emergency system is used for protecting high speed vehicles levitated by magnetic or air cushions. In order to ensure that neither the vehicle nor its track is damaged when the levitation mechanism fails, a number of sliding shoes are provided on the vehicle. These have vertically projecting bristles or thin plates. The plates are arranged with their planes across the travelling direction of the vehicle. The vehicle sinks gently on the bristles or on the plates and is not damaged on sudden failure of levitation. Ice is produced within the sliding block by means of a refrigerator plant in the vehicle. This ice is used to absorb heat generated due to friction and for providing lubrication for sliding.

Title: Car boot elastic sealing section - has U-shaped steel reinforced holding- and hollow soft foam material sealing part
Inventor: BURGMEIER GUENTER
IPC: B60J10/32
Filed: 1973-10-03
Abstract: Sealing sections of the type as used for instance for sealing car boots, the problem is to secure permanently the section to the car body. Soft foamy sealing material with a minimum of permanent deformation offer rather poor characteristics for application by using adhesives. By using for the holding part a chloropren-type heavier material and reinforcing it, a more stab fixing base is created which, due to the absence of internal stresses in the material sticks to the car body. The hollow sealing part is fitted to the base by a lip at one end of the section and a shaped part overlapping the edge of the base at the other end of the section.

Title: Counting translation in a telephone junction line - with time measured by keying of a D.C. voltage applied to one of the wires
Inventor: SEDLMAYR OTTO
IPC: H04M15/10
Filed: 1974-01-22
Abstract: The keying is performed by a device which controls the start and end of counting. A capacitor shunting a keyed resistor is inserted only in the wire carying the counting pulses. Its capacitance is such, that the application of d.c. voltage at the connection beginning immediately makes operative switching means in the preceding selector stage for the counting pulse reception and retransmission. This device also evaluates signals transmitted over the other wire e.g. flashing signals and earth returns; this evaluation is followed by stopping counting pulse generation. An inductance is in series with the keying contacts in the form of an electronic switch.

Title: Gas purging/vacuum degassing non-ferrous melts - in closed channel-type inductor furnace from which casting can take place under pressure
Inventor: SOFINSKI PAVEL I DR ING
IPC: C22B9/00
Filed: 1974-06-08
Abstract: The ladle-shaped furnace has a sealing lid which may be swung to one side for charging. The flat bottom contains four or eight porous bricks through which Argon can be fed from a common ring main. An outlet pipe near the top of the furnace can be connected either to a vacuum pump or to a source of inert gas. If the furnace has been filled with molten metal, e.g. Al Argon or similar inert gas is bubbled through, the resultant gas mixture being bled off through the top outlet to atmosphere. Gas flow is then stopped and a vacuum of several mmHg applied. At the end of degassing, the top outlet is connected to the inert gas supply and the metal is forced up the casting tube for use either in pressure casting, or continuous casting, without coming into contact with the air. Oxidation is therefore prevented and sound gas free metal is produced.

IPC: G01F1/32
Filed: 1974-08-28
Abstract: Deflectors (12, 13) deflect the flowing medium with respect to the pipe (10) axis by an angle smaller than (90 deg.).

Title: Earthing protection circuit for synchronous generators - has thyristor or mech. switch connecting impedance to stator transformer
Inventor: STROBL JOERG DIPL ING
IPC: H02H7/06
Filed: 1974-09-27
Abstract: The protection circuit, for a synchronous generator star-coupled stator windings, protects the windings from shorts to earth using an approx. linear impedance which is switched across the secondary of the transformer coupled to the generator phase lines or to the winding neutral point. The imedpance either capacitive or inductive, limits the current flowing to earth. The switching is achieved either with a low voltage mechanical switch or with two anti-parallel thyristors. A primary circuit breaker is connected between the mechanical switch and the impedance. The circuit affords protection not only in cases where the transformer is coupled to the phase lines but also when it is coupled to the star-coupled winding neutral point.

Title: Contacts for network of wires - are manufactured by pulling out loops stripping insulation and soldering
Inventor: ZELL KARL
IPC: H05K13/06
Filed: 1974-09-30
Abstract: A network of wires is formed which acts as a switching device. Horizontal switching wires run in the (X) direction and are associated with horizontal switching wires running in the rods (10). These rods pass through holes in plates (5, 5') between which the horizontal wires are sandwiched. The rods are fastened to a baseplate (4) and pass through a plate (3) which may be pulled away from the baseplate when the formation of the loops is complete. The loops of wire which were pulled out by the ends (2) of the rods may then be dipped in a bath which dissolves away the insulation. A further set of rods is introduced and the loops are soldered.
