Title: Carpet yarns with splashes of one or blended colours - printing, staple and draft determine length and spacing
Inventor: KAJUETER EWALD ING GRAD
IPC: D06B11/00
Filed: 1975-01-22
Abstract: Mfr. of flame yarns, esp. for carpets, in which a stretched and unified web of fibres, opt. pre-dyed in one colour, has dyestuff or reserve agent patches applied at spacings between them equal to or greater than the staple length of the web of fibres, and in which the zones between the patches free from dyestuff or reserve agent extend across the full width of the fibrous web; the web of fibres being fixed, washed, dried, etc., and then spun without preliminary stretching. For the prodn. of flame yarns with a flame length (F), the flame printing length (A) is chosen on a basis of the equation:- A = F/2-S.V. (where (S) is the staple length, and (V) the draft). Similarly, where it is desired to space out the fames at a pitch greater than the staple length of the fibres, the equation:- A = F/2 - S.V./2, is used. Improves the technique for flame yarn prodn., esp. yarns with blended colours. The length of the flames can be determined by the choice of the printing length relatively to the staple fibre length with a definite draft. Inversely, when for any reason the printing length is predetermined, the staple length can be selected so as to give the required length of flame.

The sunlight radiation is measured by a light scanner, and the temperature of the surfaces absorbing the solar energy is simultaneously measured by a sensor. a certain measured value combination is both sensor and scanner automatically switches in a circuit, limited to the heat store and water heater, excluding the absorbent surfaces. Parallel elements of the heat store are individually switched into the circuit.
Patent DE-2513606-A1 (DE)
Title: Data transmission network with data blocks switched between loops - uses reduction in loop address difference as switching criterion
Inventor: BOERNER MANFRED DR RER NAT
IPC: H04Q11/04
Filed: 1975-03-27
Abstract: The data transmission network consists of a matrix of transmission paths connecting loops at the junctions where orthogonal paths meet. Data blocks are transmitted through the network by addressing these junctions. The data blocks are provided with loop address differences for path hunting and occupy arbitrary time slots, only the bits within a block having a fixed phase relationship. A reduction in the loop address difference is used as a criterion for the further switching of any data block. The advantage over other such loop networks lies in reducing the number of stores at the loop junctions and in simplifying block transfer from one loop to another.
