Patent DE-4107639-A1 (DE)
Inventor: KNIGHT ALAN C
IPC: B61L27/00
Filed: 1991-03-09
Abstract: In the remote-control of substations (UST1) in railway systems, a control command which triggers a control action with a responsibility for safety is initially transmitted without fail-safe security into the substation. Subsequently, the control action is reflected back into the central control station (Z) via the transmission path which has been configured in a fail-safe manner, before said action is carried out. After a further check of the control command, an execution command which acts in a fail-safe manner is transmitted to the substation. A security code which is produced in the substation and stored there is used as the execution command. Said code is transferred to the central control station together with the control action to be reflected back. Said code is input again into the central control station as an execution command, transmitted to the substation in a non-secure fashion and compared there with the original security code. If they correspond to one another, the control action is carried out.

Title: Two-ply yarn folding - has automatic splicing at reel changeover or resulting from a broken end
Inventor: UCHIDA HIROSHI
IPC: B65H63/02
Filed: 1991-11-29
Abstract: On a two-fold doubling frame, yarn is spliced automatically by a service robot which picks up the ends from both supply reels, having been forced upwards by air pressure. Auxiliary pressure is also given to the anti-ballooners, so that a suction tube can pick up both threads at the tension section, to lift them across a thread separator, and into the double splicer. At the same time a suction tube withdraws two-ply yarn from the creel, lays it in a separator device, and into the double splicer. Pref. the frame consists of a series of units, each with two reels of supply yarn (1(2)) which are mounted on tubes with air pressure supply (10). There is auxiliary air pressure (11) to the anti-ballooners (12). The yarns are then united in the guide (14) and taken around tension rollers (15). A cutter mechanism (16) serves the same purpose as on a winding frame, and the two-fold yarn is then wound on to the reel (3) by a traverse mechanism (4). In the event of a broken end or expired supply reel, this is detected by the sensor (13), which will stop the section, and attract the service robot (R). The service robot contains a suction tube (5) which reaches to the reel (3) and withdraws some two-ply yarn. The arm (5) then swivels down below the separator device (8), which unfolds the yarn into two separate components, which are able to enter the separate slots of the two splicers (7). The broken ends, or the new ends from the new supply reels will be forced through by air pressure (10,11) and the suction arm (6) in the robot will reach down to the tension arrangement (15), taking the two-ply yarn up across the separator device (9), which releases the yarn into two separate components in order to enter te slot of the two splicer units (7), along with the yarn brought down from the creel. When spliced, the winding re-commences, and surplus yarn is cut away by the mechanism (16). ADVANTAGE - The process is carried out automatically, whereas previously this has been a tedious manual operation.

Patent DE-4202809-A1 (DE)
Inventor: SCHOEFFMANN WALTER ING GRAD
IPC: C02F1/68
Filed: 1992-01-31
Abstract: The quality of water is characterized by various viscosities, pH-values and biological purity degrees, as well as by various energy contents and electric load states. This vibratory energy is particularly intense in mountain streams, on the contrary to tap water which is extraordinarily poor in energy, qualified as "dead" water, and chich is correspondingly less wholesome, although not prejudicial to health. A device for cleansing and vitalizing water has at least one solid crystal, a precious gem, a semi-precious stone, a rock crystal or a globule which increases the energy content of the water arranged in a water stream that is made to swirl by means of an agitator or a pump. Water swirling associated with crystals may also take place in flow fittings. In order to treat larger amounts of water, it is appropriate to successively connect several reaction chambers in a multistage pump or to connect in series several pumps with intermediate reaction chambers. This device is useful for cleansing and vitalizing water, making it more fresh and wholesome.
