Title: Tracheal tube having connecting and fixing devices
Inventor: DOUVLIS ZINON DR MED
IPC: B29C65/00
Filed: 1983-01-05
Abstract: The invention relates to a tracheal tube having a connecting device which is intended for connection of the outer end of the tube to an artificial respirator, and having a fixing device for fixing the other end of the tube in the trachea of the patient. The invention was based on the object of largely eliminating the risk of contamination during artificial respiration by means of special precautionary measures on the tracheal tube or in connection with this tube. The invention consists in that a wall which bulges over the overlap region and delimits an open annular space is provided along the outer circumference of the connector and the nozzle of the connection device at a distance from the terminal edge thereof corresponding to the overlap region, and in that the walls of the corrector and nozzle are matched in shape and dimensions in such a way that their free edges rest sealingly against each other in the closed position and the walls thus form a closed chamber which surrounds the overlap region and protects against contamination. In the embodiment shown in Fig.1b, the annular chamber K which is delimited on the outside by walls 7b, 7b' and protects against contamination has an approximately semicircular cross-section and is provided with connectors 8 for passage of air and/or gas. The surfaces of the nozzle 4 and connector 5 which come into contact in the overlap region consist of a metal (B) with an oligodynamic (bactericidal) action. <IMAGE>

Title: Process for the combined preparation of methanol and ammonia
Inventor: WILL HERBERT DR
IPC: C01C1/04
Filed: 1983-10-08
Abstract: A process for the combined preparation of methanol and ammonia by catalytic vapour cracking of light hydrocarbons, preferably methane, is to enable the stripping gas from the methanol synthesis not to be simply burned nor to be converted to ammonia synthesis gas in an expensive process. Simple processing expedient in terms of cost to give ammonia synthesis gas is desired. According to the invention this is achieved in that the hydrogen-containing stripping gas from the methanol synthesis is purified in a known manner to synthesis gas quality and the addition of nitrogen is carried out by burning hydrogen at elevated pressure with air in a hydrogen stream. <IMAGE>

Title: Filling device for fuel tanks, in particular for motor vehicles
Inventor: HANKE FRIEDRICH
IPC: B60K15/04
Filed: 1984-09-07
Abstract: The invention relates to a filling device for fuel tanks, having a tank connecting branch and a filler neck connected to the latter and leading upwards. Provided in the region of the tank connecting branch is a non-return flap pivotable about an axis. During the filling operation, the said non-return flap can be pivoted into its open position by inflowing fuel and pivoted into its closed position by fuel slopping back out of the fuel tank. An advantageous arrangement of the non-return flap requiring neither measures at the filler neck nor at the tank connecting branch for fastening and securing it with adequate mobility is here made possible by the fact that the non-return flap is mounted pivotably on a bearing body which has a passage that can be closed by the non-return flap and can be inserted into the tank connecting branch or into the filler-neck endpiece connectable to the tank connecting branch or into a connecting hose which connects the endpiece and the tank connecting branch to one another.

Title: Embroidering machine
Inventor: COMPLOI GEORG
IPC: D05C5/02
Filed: 1984-10-01
Abstract: Arranged in at least one row is a relatively large number of embroidering stations with corresponding embroidering tools which can be coupled to or uncoupled from the driving means of the embroidering tools by means of electromagnetic actuating devices (13) according to a predetermined repeat and colour-change program. Some embroidering stations or their electromagnetic actuating devices (13) respectively form switching groups (7, 7'), the electromagnetic actuating means (13) of each switching group (7 or 7') being switched in parallel on the input side and being connected to an embroidering-station control device (14) via a group-specific feed line (6 or 6'). On the output side, the individual electromagnetic actuating means (13) of all the switching groups (7, 7') are series-connected to the embroidering-station control device (14) via a number of feed lines (5) corresponding to the number of electromagnetic actuating devices (13) per switching group (7 or 7'). These measures and an optimum choice of the number of embroidering stations, here especially four per switching group, thus achieve a minimum of electrical feed lines and a very rapid switching through of all the switching groups, along with a minimum power consumption. <IMAGE>

Title: Small gas turbine with gas dynamic rotor wheel cooling
Inventor: MAYER KARL
IPC: F02C3/045
Filed: 1984-10-04
Abstract: Since the piston engines hitherto used in small appliances of all types and in small vehicles to drive them not only represent a source of environmental noise but also pollute the environment with a considerable emission of pollutants, replacement of the piston engines hitherto used by a small gas turbine suggested itself. The small gas turbines hitherto available or for which patents have been filed have the disadvantage, however, of being either too expensive to manufacture, or functioning, if at all, with considerable disadvantages, such as too high temperatures. In the subject of the invention the disadvantages have been overcome and a small engine created which is cheap and simple to manufacture and can be operated using any commercial fuel, liquid or gaseous. A single rotor wheel assumes the function of compressor and turbine and is flushed by cold air throughout its rotation in order to cool it. The hot gas entering the rotor wheel downstream of a burner or a combustion chamber transmits its power, at first mostly by way of a cold air cushion, to the blades of the rotor wheel and is then centrifuged by the cold air into the exhaust duct, without being able to transmit high temperatures to the blades. Due to the high admixture of cold air to the hot gas, the exhaust gas temperature is low and the proportion of air very high, so that the exhaust gas ... Original abstract incomplete.
