Title: Empty spool sleeve conveyor - with sleeves transferred from conveyor in intermediate magazine and from magazine in spool position
Inventor: ROHNER HOACHIM
IPC: B65H67/04
Filed: 1975-02-15
Abstract: Empty spool sleeve continuous conveying equipment in a spool position on a textile machine has an intermediate magazine (29) positioned within working range of a sleeve moving device (57) of a movable spool changing equipment (56) and moves from the continuous conveying equipment an empty spool sleeve (51) which by means of a switch (47) positioned on the conveying equipment as it is brought in a sleeve transferring position (106). When the empty sleeve is required, the sleeve moving device (57) of the spool changing equipment (56) removes the spool sleeve (51) from the intermediate magazine (29) and transfers it to the spool position (12). Subsequently the empty intermediate magazine (29) swings back within the conveying range of the continuous conveying equipment.

Title: Lost casting pattern - made of vacuum bag with outer flexible foil, porous backfilling and cover foil
Inventor: BENNER ALWIN DIPL ING
IPC: B22C7/02
Filed: 1975-02-21
Abstract: A patern can be produced, for embedding in the sand of a moulding box, of a material which is gasified by the effect of hot metal. The pattern surface is made of a flexible foil which renders the desired contours and surface finish of the casting. It is backfilled with a porous gasifiable material, backed by a second foil which is joined gastight to the first so that a vacuum can be maintained between them. This produces castings with a better surface finish than when the pattern is made of blocks of polystyrene foam. The pattern can be produced in large quantities automatically and produces smooth surface finishes even for complex surfaces.

Title: Non-woven flax fibre fabric mfr - using non-retted flax fibres still contg pectins and lignin
Inventor: ROELOFFZEN JOHANNES FRANCISCUS
IPC: D04H1/04
Filed: 1975-03-13
Abstract: A fleece constructed from non-woven, randomly oriented flax fibres is mfd. from flax fibres produced by dry breakage and swingling of the flax stems to remove wood by opening the fibre bundles mechanically, so as to leave the pectins and lignin material bonded to the fibres, bringing the fibres so produced into fleece form and after mixing with a binder (partic. an aq. dispersion of a butadiene-styrene copolymer), subjecting the fleece to a heat treatment, partic. at 60-70 degrees C. By eliminating the usual flax retting process, the pectins and lignin remain in the fibres and enable the addition of binder to be kept to a relatively small amount. Furthermore the flax treatment process is simplified and atmospheric pollution or effluent problems eliminated.

Title: Silver recovery and regeneration of photographic fixing bath - by electrolysis in diaphragm cell
Inventor: KITAHARA TOHRU
IPC: C25C1/20
Filed: 1975-07-17
Abstract: The recovery of Ag from a photographic fixing soln. is achieved by electrolysis of the spent soln. in a diaphragm cell. A porous diaphragm with a pore dia. of ca. 0.01-50 mu is pref. e.g. a semipermeable membrane, a porous membrane or synthetic fibre cloth. This separates a vol. of the soln. around the anode from teh remainder, the vol. around the anode pref. being max. 30% of the total vol. Electrolysis pref. takes place at a cathodic current density of 0.001-10 A/100 cm2 and at 0.5-2.5 V. The process is efficient, simple and economical and the use of a diaphragm reduces detriment to the fixing soln. by oxidative decompsn. of S2O3= or SO3= ions at the anode.
Patent DE-2533001-A1 (DE)
Inventor: JAEGER HORST
IPC: H04Q1/44
Filed: 1975-07-23
Abstract: Primary and secondary signals (HK, NK) are exchanged during the exchange of switching signals in connection traffic between primary and secondary systems. In this exchange of switching signals, a dial pulse string arriving after the transmission of an end-of-dialling signal (HK11) and before the transmission of a subsequent telephone-station-free-signal or telephone-station-busy-signal results in transmission of the abovementioned signals which is delayed by a specific predetermined time following the arrival of the last dial pulse. Low-frequency and audio-frequency signals are used as switching signals. This is intended to ensure correct transmission and evaluation of the free or busy signal even in the event of fast suffix dialling by the calling subscriber. <IMAGE>

Then the required sintering pressure for this temp. is applied and the temp. is raised to a second temp. (T2), pref. 1350 degrees C, at this or higher pressure. The sintered part is then cooled. The ferrite is used for magnetic heads for audio, memory or video applications. Large-grained ferrites with regulable grain size can be produced.

Title: Measuring machine probe head with inductive transducers - has interchangeable probe moving in three axes and is fitted with pneumatic zeroing system
Inventor: WILKEN ENNO
IPC: G01B7/012
Filed: 1975-08-07
Abstract: The measuring machine probe can take measurements along all three axes and is suitable for use in a profile cutting machine.
