IPC: G01S13/93
Filed: 1981-09-05
Abstract: The invention relates to an information transmission system having fixed and mobile transmitting and receiving stations.

Title: Heat lock-out device
Inventor: GLIMMERFORS RUNE
IPC: F24H9/12
Filed: 1981-09-07
Abstract: A device which is intended to prevent hot water from flowing in through an outlet (4) of the radiator in a turned-off central heating radiator of a so-called single-pipe system, which would risk turnoff, has an inlet (2), which is connected to the system, and outlet (5). In this case, the outlet is partly connected to the inlet through a bypass duct (6), and partly connected to the outlet (4) of the radiator. The device serves firstly effectively to prevent hot water flowing in the radiator through the outlet thereof, and secondly to permit economic production of the connecting piece (1) of the radiator. According to the invention this is achieved in that the outlet has an extension formed as a vertical, cylindrical duct (7) and having an upper end which is located at a higher level than that of the radiator outlet. Pushed into the duct as a loose insert is a flow guide (11) which splits the duct into two parallel flow passages (13, 14) which are longitudinally aligned in the duct and are connected to one another at the upper end of a duct. The lower ends of the flow passages are connected to the inlet and outlet, respectively, of the radiator. <IMAGE>

Title: Process for vapour-coating a surface
Inventor: DOI YOSHIHIKO
IPC: C23C14/08
Filed: 1981-11-06
Abstract: In a physical vapour-coating process, hard compounds are deposited homogeneously and firmly on the surface of cutting tools, wear-resistant parts and ornaments, such as a clock housing and the like, in order to improve the wear resistance, temperature resistance and the appearance and the like of the tools, parts or ornaments. The invention provides a physical coating process in which a solid solution containing one or two compounds selected from a group comprising carbides, nitrides or oxides of metals belonging to groups IVa, Va and VIa of the periodic system of elements and/or aluminium oxide and zirconium oxide are deposited on the surface of said tools, parts or ornaments in the form of a single layer or a plurality of layers. The process is characterised in that the surface of the tools and the like is subjected to a sputter cleaning in an atmosphere of hydrogen or a gaseous mixture of hydrogen and an inert gas containing at least 20% by volume of the former, in order to clean the surface of the tool and the like uniformly. The adhesion of the deposited layer consisting of these compounds to the tools and the like is improved and becomes more uniform, and this results in a further improvement of the diverse properties mentioned of the tools and the like. <IMAGE>

Patent DE-3207708-A1 (DE)
Title: Magnetic interference suppression device
IPC: G01R33/025
Filed: 1982-03-04
Abstract: In this magnetic interference suppression device for wide-area DC and AC magnetic fields, the interference field is picked up three-dimensionally by two or three receiver coils periodically moved at the angular frequency @ and is supplied again three-dimensionally at a distance therefrom via lock-in amplifiers to a system comprising three pairs of Helmholtz coils. The field inside the Helmholtz coil system is compensated through suitable polarity of the coils. The lock-in amplifiers are controlled by the angular frequency @. Three measuring coils in the area where interference is to be suppressed can help to reduce residual fields with the aid of servo systems. The invention can be combined with conventional compensation with fixed receiver coils.

Title: Device for measuring the concentrations of a gas, in particular ozone
Inventor: HUEBNER KARL-ALEXANDER
IPC: G01N21/33
Filed: 1982-06-09
Abstract: Compared with previous instruments, a device for measuring the concentrations of a gas, in particular ozone, makes a handy compact construction possible by largely eliminating various sources of error which were previously present. Incidentally, it is also intended to achieve an immediate measurement without waiting times for very small volumes of ozone, for example parts of an ozone injection filling, by flash triggering the light tube. For this purpose, the light source (UV tube with an interference filter in the beam path) is followed by a beam splitter (quartz glass arranged at 45 DEG  to the beam entrance) having an optical aperture. The deflected beam from the beam splitter falls directly on a photodiode (reference receiving channel) and the transmitted beam falls on a second photodiode (signal receiving channel) with the measuring cell (ozone chamber) inserted inbetween, both measurements being indicated by a comparison circuit. <IMAGE>

Title: Television system with intercarrier sound receiver
Inventor: SCHROEDER ERNST DIPL ING
IPC: H04N7/06
Filed: 1983-02-25
Abstract: In a television receiver according to the intercarrier sound principle, the sound signal obtained in the receiver is impaired by phase errors in the vision carrier. According to the invention, the sound carrier is mixed with the modulated vision carrier in the transmitter. The sound carrier then has the same phase errors as the vision carrier in the receiver so that there are no phase errors in the intercarrier signal.

Title: Power transmission arrangement with resistance to extension
Inventor: KLEIN HELMUT
IPC: E05F11/48
Filed: 1983-03-16
Abstract: In a power transmission arrangement with resistance to extension, intended in particular for motor vehicle window winders, having a flexible tension member, on whose flexible core carriers are provided in the form of rotary bodies each having spacers situated between them for engagement of a drive or output drive member, the rotary bodies are composed of rubber or entropy-elastic plastic and, with the spacers, are connected firmly to one another and to the core with uniform material engagement by being vulcanised or sprayed onto the core, e.g. a wire cable. A tension member of this type makes the power transmission arrangement insensitive to production-related tolerances. Changes in length of the tension member caused, for example, by temperature or wear also have virtually no effect on the precision of the drive since the entire tension member carries out changes in dimensions equally due to the intimate bonding of the carriers to the core.

Title: Calotte shell and use thereof in a method for finishing chains
Inventor: HALL KARL FRIEDRICH
IPC: A44C11/00

Abstract: The invention relates to a calotte shell (1) and the use thereof in a method for finishing chains, in particular chains of pearls (15) or other jewellery elements which are threaded onto at least one double thread which is resistant to breaking or a double pair of threads (11). In addition to the opening which is formed by the cutout (3) from the spherical body (2), the calotte shells (1) have a bore (7) on the outside of the spherical body (2), through which bore the threading needle (8) can be pulled. In this manner, a knot (13, 16), provided with a drop of adhesive (14, 17), at the end of the double thread (11) is given a precise position inside the spherical body (2) for curing or bonding the adhesive (14, 17), which prevents detachment between the thread ends and the respective calotte shell (1). <IMAGE>

Patent DE-3336743-A1 (DE)
Title: Plastic composition for plastic facing sheets and adhesives
IPC: C09J131/04
Filed: 1983-10-08
Abstract: Plastic compositions for the production of plastic facing sheets should be sufficiently elastic and reliably bondable, and in addition fire prevention demands are made. It has been found that plastic compositions which allow both the production of a plastic facing sheet and the preparation of an adhesive for these facings can be produced on a vinyl basis with addition of plasticisers, the necessary elasticity and flame resistance being achieved by employing as plasticisers, chlorinated alkyl compounds and/or organic phosphoric acid esters. The structure of the facings is achieved by structure-forming additives, added fibres preventing the facings cracking when bent around tight corners.
