Title: Indicator lamp avoiding soldering in mfr. - has plug pins with conical parts conforming to cross=section of connection conductor
Inventor: SCHROEDER ERICH
IPC: F21S8/00
Filed: 1979-04-06
Abstract: The indicator lamp has the ends of the plug pins inside the casing provided with conical parts conforming to the cross-section of the connection conductor of the lamp. Each plug pin is secured against spreading radially by guide walls formed on the bottom of the casing. The conical parts run centrally from the end face of the pin coaxially with the long axis. The pins project slightly from the bottom of the casing into the casing proper. The conical part is located in the region that protrudes. A blind holds a resistor. The advantage lies in simplicity and in being able to use semiautomatic fabrication without soldering.

Title: Tape heading for curtains hung from track - has minimum stiffness ensuring folds extend vertically from top edge to floor under own weight
Inventor: RANDOLF HEINZ
IPC: A47H13/12
Filed: 1979-11-10
Abstract: The curtain tape which is switched onto the curtain beneath the upper edge has a predetermined minimum stiffness to provide a firm heading connected to the curtain track or similar by holders which are rotatable about their vertical axis. At the freely movable end of the curtain at least one holder contains a brake element which acts against the track so as to prevent the displacement of the curtain by friction. The folds for the curtain now hang evenly down from beneath the point where the curtains are fixed to the track. The absence of gathering reduces the accumulation of dust.
Patent DE-2949917-A1 (DE)
Title: Electromagnetically induced vibration process for steel tubes - silently vibrates tubes passing through powder-melting lining installations for even covering
Inventor: LOSEMANN WOLFGANG DIPL ING
IPC: B06B1/04
Filed: 1979-12-12
Abstract: The vibration unit comprises a one-way rectifier, >=1 coil, the steel tube to be vibrated and abutments. The rectifier which is connected to the coil(s) can be connected up to a frequency-variable AC generator or the normal AC mains with 50 Hz. The coil(s) is connected between two abutments Pref. above or below the tube to be vibrated whilst the tube serves directly i.e. without further mechanical transfer elements, as the yoke for the coil although it does not actually contact the coil. The lack of mechanical vibratory means ensures the noise level is minimal. The one-way rectifier allows the AC to be converted into a pulsating DC which still only consists of the positive or negative semi-wave of the AC current.

Title: Crosslinking moisture-crosslinkable coiled material - in sealed chamber, by sucking out air mixing with satd. steam and reintroducing steam-air mixt.
Inventor: FLIEHS HEINRICH ING GRAD
IPC: C08L43/04
Filed: 1980-01-30
Abstract: Polymers, e.g. olefin (co)polymers, thermoplastics or thermoplastic elastomers, rendered moisture-crosslinkable by grafting crosslinking auxiliaries, e.g. organosilanes, are crosslinked as extended materials, wound on drums or reels, by storage in a steam atmos. Novelty comprises introducing the drum or reel with the wound-up material into a chamber which can be hermetically sealed. The air present in chamber as well as in the layers of material is removed by suction, mixed with highly tempered satd. steam and re-introduced into the sealed chamber as a low tempered steam-air mixt.. Suction, mixing and re-introduction is continued until reaching the crosslinking temp. and then also for maintaining the crosslinking temp. during crosslinking The materials can be electric cables or conduits, pipes or hoses and profiles. Heating-through and penetration of coiled material layers is accelerated. The crosslinking temp. can be kept low enough not to damage the material. Crosslinking time is reduced.

Title: Automatic track launching system with tracking braking - has doppler radar unit determining instantaneous value of wagon speed and fixing brake release time
Inventor: MUELLER HANS-JOACHIM ING GRAD
IPC: B61K7/12
Filed: 1980-09-26
Abstract: In an automatic track wagon launching system, the speed of the launched wagons is controlled by track brakes. The speed is regulated to a reference value by varying the braking force of the rail brake. The actual speed of the vehicle is determined by a radar system from which the lead is deduced. A Doppler radar instrument is used by the control unit on a rail brake to determine the instantaneous value. The release time of each brake is measured and the result from one or several of the preceding braking times used in the calculation of the lead.

Title: Blood vessel catheter has introducing needle - inside catheter tube and retractable into tube after puncture
Inventor: HAINDL HANS
IPC: A61M25/01
Filed: 1980-11-27
Abstract: A flexible tube catheter for introducing into a blood vessel has a needle of the same diameter as the interior of the tube slidably mounted in the tube; the point (3) of the needle projects out of the tube, while the rear end of the needle has a pulling device, esp. a steel wire (6) welded to the needle, to enable it to be pulled back into the catheter tube. The front end of the catheter tube (4) is pref. conically tapered. The needle itself may have a longitudinal duct in its wall. Its tip may be similar to that of an injection or syringe needle. A clamp (5) fitted onto the catheter may have a projection (19) near the rear end of the needle, so that pressure applied here holds the needle in position in the tube while it is being inserted. It can later be pulled back by the wire (6). With this arrangement, a complete reversal of the conventional principle of using a needle larger than the catheter tube is adopted, with resultant less damage to the tissue of the patient and less risk of infection etc. Pulling and pushing handles (9,13) are attached respectively to the pulling wire (6) and to the rear end of the catheter tube.

Title: Microbicide effective against microbes which affect the lungs - contains calcium hypochlorite and water which produce hypochlorous acid, which produces iso:hypochlorous acid which releases active oxygen
Inventor: ANDERSON RUDOLF DR MED
IPC: A61K33/20
Filed: 1980-12-09
Abstract: The prepn. of a microbicide effective against microbes which attack the lungs follows the equilibria for the reactions between calcium hypochlorite and water to give Ca2+, OH- and HOCl. The hypochlorous acid formed reacts further with RH to give ROH, HCl, H2O and RCl. The microbicide can also be used against osteomyelitis, acute suppurations of wounds and anaerobic infections, as well as against lung infections, esp. those caused by antibiotic resistant bacteria, or allergic reactions. The extremely low cost of the process allows the microbicide to be used in mass infections sic as an antimicrobic prophylactic e.g. in radiation sickness (sic).

Title: Physiological functions monitor - has filter and discharge circuits for high amplitude signals
Inventor: SCHNEIDER SIEGFRIED DIPL PHYS
IPC: A61B5/11
Filed: 1980-12-29
Abstract: The monitoring system is designed to detect irregularities in the respiration, heart beat and body movements of infants. The problem of signal overlap and cross modulation with high amplitude signals is solved by the use of filters for selecting the required signals and a discharge circuit for high amplitude signals. The output of the signal amplifier (1) goes via a filter (5) to a second amplifier (6) the output of which is processed for audio/visual display. Signals with amplitude above a certain value are blocked by a bypass circuit (4), which, in a further development, is microprocessor controlled.

Title: Seat-belt arrangement for vehicles, in particular motor vehicles
Inventor: MUELLER HELMUT E ING GRAD
IPC: B60R22/20
Filed: 1981-03-28
Abstract: A seat-belt arrangement for vehicles, in particular motor vehicles, has an upper belt-deflection means which is mounted on the vehicle, is height-adjustable in steps and is situated approximately at the shoulder level of the vehicle passenger. Serving as the upper belt-deflection means is a plate (12, 12a) which is fastened to the vehicle body (10) and has a plurality of belt-guide slots (17, 18, 19; 17a, 18a, 19a) which are offset in height to one another and open, at an acute angle, into a common, lateral belt-mounting slot (20, 20a). By this means, an upper belt-deflection means which can be produced and mounted simply and only requires a low outlay in terms of cost is provided. This belt-deflection means is moreover distinguished by a low overall height (h) and thus ensures that the vehicle occupants are well protected, even in the case of side impacts, in a manner which will satisfy future legal regulations. <IMAGE>
