Title: Tensioning yarns passed through brakes
IPC: B65H59/24
Filed: 1971-04-23
Abstract: Yarns passed through brakes in spinning machines have their tension controlled by exposing the yarns on the one hand to the clamping force of the brake jaws one of which is resiliently mounted to exert the basic tension and on the other hand to the compensating flexure of a resilient guide mounted on the resilient brake jaw and securing the stability of the tension.

Title: Melt agitator - for effecting metallurgical reactions by the uniform mixing of slag and melt
Inventor: SCHULZ HANS PETER DR ING
IPC: F27D27/00
Filed: 1971-09-30
Abstract: Molten metal is mixed with a reactive slag in order to bring about metallurgical reactions by an agitator comprising two refractory, beam-like agitator members that are rotated by two perpendicular shafts equipped with drive mechanisms and protected at their lower ends by refractory material. Two agitator members rotate in the same sense, but their rotational speeds vary. The distance between the axes of the two shafts is equal to at least half the sum of the lengths of the agitator members. The agitator members are relatively small, yet can rapidly and reliably mix large quantities of melt.

Title: Controlling whisker growth - by means of non-uniformly dispersed catalyst
Inventor: TOMITA CHUJI
IPC: C30B25/00
Filed: 1972-07-24
Abstract: Catalyst reducing the activation energy of whisker formation is non-uniformly dispersed in the main substance, whereby it locally exerts action promoting the whisker formation. The catalyst (e.g. NiCl2, PdCl2, FeCl2, etc) is used in an amt of 0.001-5.0 atom % (w.r.t. the main substance). By this method, whiskers which can be used as a reinforcing element for various materials, can be produced in a relatively simple and economical manner (e.g. WM Mo, SiC or B4C whiskers).

Title: Determining water concs. of parts per billion - using charge for electrolysis of absorbed water which is proportional to quantity
Inventor: KLOFT FRANZ-RUDOLF DIPL PHYS
IPC: G01N27/42
Filed: 1972-11-11
Abstract: A method of determining extremely small quantities of water, esp in the parts per billion range, consists of conducting the sample at constant speed through an absorption cell contg a water-absorption agent and electrodes immersed in it. Water is first stored in the absorption agent for a sufficient time for the electrical charge to be supplied for the latter electrolysis to be sufficiently above the creep and leakage effects to be proportional to quantity; electrolysis is then carried out by integrating the electrolysis current with respect to time: storage and measurement phase are then regulated to a defined time programme.

Title: Remote control system - has cct for storage, evaluation and display of messages in form of coded telegrams
Inventor: LISSNER PAUL
IPC: G08C19/28

Abstract: Telegrams contain as many signal elements as there are informations allocated to different operational states. The reported states are displayed by signalling lamps. It comprises a first gate in which the received signal is compared step-by-step with the preceding telegram stored signal. A second gate compares the change information detected by the first gate with an earlier change information stored in a corresponding store. The detected incoming and outgoing information changes are stored in the change sore under a timing element control. An acknowledgement signal causes the transfer of the telegram store content to a message store, erasure of the change store and timing element resetting.

Title: Tangential air blower with volute wall - has semi-circular inlet edge to volute wall to reduce noise
Inventor: ZINSSER RUDOLF DR ING
IPC: F04D17/04
Filed: 1974-01-04
Abstract: The blower has a long cylindrical rotor with a discharge volute formed by a guide plate and a volute wall.
