Title: Polytriazine from aromatic cyanate, with imino-carbonic acid ester - giving polymer with good sensitivity to moisture, elasticity and flame resistance
Inventor: SUNDERMANN RUDOLF DR
IPC: C08G73/06
Filed: 1975-08-13
Abstract: Polytriazines are prepd. by polytrimerisation of cyanates of formula Ar(OCN)n (I), (where Ar is an aromatic residue, opt. interrupted by bridging gps., and n = 2-5) or of prepolymers from (I). Polymerisation is in presence of 0.1-70 (10-40) wt. % of is not 1 iminocarbonic acid ester (II), wrt (I) + (II) and opt. of a polymerisation catalyst. The physical properties of the polytriazines depended on the amount of (II) used. Polymerisation is in bulk or solution optionally first to a prepolymer. Prepolymers are used, as powder of solution to form coatings, as impregnants, as laminating resins, or two form moulded goods.

Title: Plastics straps and posts for ground stabilisation support - has parallel straps reinforced with diagonally wound adhesive straps
IPC: E02D17/20
Filed: 1975-09-13
Abstract: The support arrangement prevents landslides, and erosion and it is used on slopes not covered with vegetation. The ground to be protected is held by vertical posts with zig zag patterned, plastics straps. The stability of the flat horizontal straps is improved by additional diagonal straps. This ensure high load carrying capacity and plant roots can grow in the gaps between the straps. The parallel straps (2) stretched between the support posts are connected with diagonal adhesive straps (2). Adhesive straps are wound in helical pattern around fencing formed from parallel straps. The adhesive surfaces exposed at gaps between parallel straps are rendered inactive by covering with fine particles, especially with grass seed. Parallel straps are held in slots in posts.

Title: Corrugated paper sleeves for packing non-circular objects - are made in several thicknesses and shaped by controlled paper feed
Inventor: MOSSE RICHARD WOLFGANG
IPC: B31C99/00
Filed: 1975-10-29
Abstract: Cylindrical sleeves made of circular spirals of corrugated paper are previously known and similar sleeves of non-circular section, in particular, of square or rectangular section may be made. After the initial layer of corrugated paper is in position, the feed rate will be controlled so as to supply extra length in the positions where the corners are to come. The method applies to the production of sleeves of oval cross section, as well as to square and rectangular sleeves. It can be used for continuous production, and makes no extra demand on material or energy supply.

Title: Powered glider with retractable nosecone - has twin shrouded meshing propellers inside fuselage to provide throughflow
Inventor: BUENDER HANS-JOACHIM
IPC: B64C31/024
Filed: 1975-11-07
Abstract: The powered glider has a retractable nosecone of circular or oval section mounted on 3 or more rails parallel with the axis of the fuselage. Retraction is from the cockpit by a handwheel on a screwed spindle. The whole is mounted on an airtight transverse bulkhead which is the forward end of the cockpit module. Between the cockpit module and the fuselage shell there is an annular space. With the nosecone retracted, air flows through the resultant opening into this space and then into a short duct behind the cockpit contg. twin propellers mounted one above the other and with the blades meshing. Driven by the propellers, the air flows on past the power unit, with a shaft to each propeller, providing silencing as well as a cooling.

Inventor: DEAK ISTVAN DR
IPC: A47J43/044
Filed: 1976-03-16
Abstract: The stirrer attachment for saucepans includes a tension retaining mechanism for an electric motor (5).

Title: Open:end spinning process - uses an inner drum with an outer drum to spin fibres by rotation where the drums touch
Inventor: LOEFFLER WILHELM DIPL CHEM DR
IPC: D01H4/16
Filed: 1976-04-29
Abstract: The process to spin staple fibres into a yarn, using the open-end spinning principle, has an outer drum and an axially parallel inner drum with the outer surface of the inner drum resting on the inner surface of the outer drum. Loose fibres are introduced to collect in the angle formed by the two drum surfaces in contact with each other. As the two drums are rotated in opposite directions, the fibres are twisted to a yarn to be drawn off. The design gives a trouble-free spinning process which operates at high speeds to deliver a high quality yarn.
Patent DE-2618933-A1 (DE)
Inventor: SCHOEFFMANN RUDOLF DIPL ING
IPC: B22D11/124
Filed: 1976-04-29
Abstract: The cooling-water jet (19) directed parallel to, or inclined with respect to, the broad side surface (2) of the strand (1) is located between the rollers (11) of the continuous-casting system or encloses the same. In order to cool the strand (1), the jet is deflected onto the broad side surface (2) by a periodic pivoting of the deflection plate (22), with the result that the jet acts on a region (27-27'). In the reverse positions, the deflection plate is located outside the jet (19) and can be stopped, with the result that the cooling power can be controlled by the number of pivoting movements per unit of time. The pressure of the jet (19) may be low and need not be changed in order to control the cooling intensity. Expensive pumping costs and pressure-controlling equipment are dispensed with. The cooling region (27-27') is determined not only by the width (23-24) of the deflection plate (22), but also by the position of the pivot pin (21). The cooling region can be changed continuously and extensively by adjusting the pivot pin (21) and can be reduced, or even increased, by a reciprocal displacing movement of the pivot pin (21). <IMAGE>

Title: Heat insulated roller shutter case - has sealing pieces fitted on outlet slit which press against shutter
Inventor: HOETGER PETER
IPC: E06B9/17
Filed: 1976-09-21
Abstract: The roller shutter, on the outside of a door or window (1) has an overhead shutter case (4) contg. a window spindle (5) and incorporating an outlet slit for the shutter.

Title: Tape cassette running time measurement - involves two shafts generating pulses whose ratio is used for time calculation
Inventor: OPELT CHRISTIAN
IPC: G11B27/13
Filed: 1976-11-05

Title: Abrasive parts prodn. using primer on abrasive grains - filler and/or reinforcement to promote adhesion to matrix
Inventor: ORTNER GOTTFRIED
IPC: B24D3/34
Filed: 1976-12-03
Abstract: In the prodn. of abrasive parts, consisting of a matrix, in which abrasive grains, filler and/or reinforcing agent are embedded, a primer (I) is added to promote adhesion before mixing and/or incorporating in the matrix. All process stages pref. take place at ambient temp. In an example, 1000 g. abrasive grains were mixed with 50 g. primer (polyester soln. in organic solvent) and dried. This was then mixed with a partly branched polyester, treated with TDI and poured into a mould. The mechanical strength of the abrasive disc was much better than that obtd. without (I). The properties of the prod. are improved by a very simple method, which does not require the provision of special costly plant and is generally applicable.

Title: Pulse counter for telephone exchanges - uses different criteria provided for counting short and long distance traffic
Inventor: DIRR JOSEF ING GRAD
IPC: H04M15/12
Filed: 1977-01-10
Abstract: Counting pulses for short distance connections are generated by switching devices for counting during local connections. Switches are provided in a higher order stage differentiating between short and long distance traffic, with different marking for short and long distance traffic, pref. in the start signal. When direct connection is made to the equivalence element, the criterion is transmited through one or several wires. A pulse train for short distance traffic is generated in the switch for counting, and if all lines to the equivalence elements are blocked, switches in the higher order connection stage, generate a different criterion for short distance traffic than for long distance traffic, pref. by different starting pulses. Switches in the outgoing translation evaluate these different criteria and transmit to the equivalence element the same criteria as in directly made connections.
