Title: Starting open=end spun yarn packages - by winding auxiliary package on core, removing it from core and inverting inside out to place yarn start outside of coils
Inventor: KAMP HEINZ
IPC: B65H55/00
Filed: 1978-06-22
Abstract: Starting yarn packages are produced as described in the parent patent by removing the spun yarn from the collecting surface of open-end spinning rotor and windint it into an auxiliary package using a core which is subsequently removed. Following core removal the inwardly disposed yarn staring end is searched and then fed to the yarn package winding station. Improvement is that the auxiliary package is inverted such that the inwardly disposed layers including the yarn start are disposed radially outwardly and vice versa. Start of yarn is withdrawn without difficulties and with reduced resistance.
Patent DE-2832071-A1 (DE)
IPC: B01D29/00
Filed: 1978-07-21
Abstract: The process, applied in the case of flowable products such as, for example, paints, ointments, gels, fruit juices etc., provides for starting, in a working step which is continuous throughout, first with venting and subsequently with simultaneous further venting and classifying. The venting can here take place in a plurality of stages, while the classification takes place during the last venting. This process can readily be carried out in an apparatus with a vessel (2) which contains both a venting device (5) and a classifying device (6). This makes it possible to carry out a comparatively rapid, simple processing of the products by classifying and venting, these two processing steps virtually merging into one another in an uninterrupted working sequence, avoiding transfer measures between these steps. <IMAGE>

Title: Dust and flame suppression during slag removal from molten iron - after desulphurisation of crude iron using agent contg. calcium carbide, graphite and polyethylene
Inventor: FREISSMUTH ALFRED DIPL ING DR
IPC: C21C1/02
Filed: 1978-08-16
Abstract: The agent contains CaC2, plus cpds. (I) releasing gases and 2-10% CaF2, so dust and flames are eliminated. The pref. mixt. also contains carbon, and possibly metals possessing a reducing effect, plus metal carbides. The pref. compsn. of the desulphurisation agent, by wt., is 30-90%, esp. 50-85% CaC2; 2-10%, esp. 3-8% CaF2; 2-10% carbon or graphite; and 2-70% cpds. (I), which pref. include 5-40% diamide lime. An esp. pref. compsn. (II) is 85% CaC2, 6% CaF2, 6% graphite, and 3% polyethylene. When slag-free iron in a ladle is treated with a mixt. of CaC2 and diamide lime (a mixt. of CaCO3 and carbon), sulphur is removed from the iron and a slag is formed which is tipped out on the ladle into slag buckets, but this slag creates excessive dust and flames. The invention eliminates this highly undesirable feature.

Title: Double refraction compensation in faraday cylinder optical fibres - by inducing axial torsional distortion prior to winding
Inventor: WINTERHOFF HORST DIPL PHYS
IPC: G02B6/44
Filed: 1978-12-21
Abstract: Deformation effects in the fibres are overcome by inducing a longitudinal axis torsional distortion such that the polarisation sense is altered with respect to the axis of the fibre cross-section elipse. Polarisation alteration is continuous and uniform over the whole fibre length. The difference in transit time for the light waves in the two optical axes senses remains small due to continuous phase changes, the sign of the difference between the two partial waves varying over the fibre length. Torsional distortion is induced into the fibre initially prior to being wound into a helical coil which can then be bent into a toroid.
