Title: Charge air cooling for exhaust turbocharger
Inventor: SONDERMANN KARL-JOSEF DR
IPC: F02B29/04
Filed: 1983-06-09
Abstract: The invention is intended, especially in the case of high-revving engines with turbochargers, to cool the compressed, hot charge air generated by the charge air turbine more strongly than occurs in radiators with airstream, the more strongly cooled charge air preventing self-ignition of the quantity of fuel fed to the cylinders earlier and more reliably and the increased quantity of cooling air passing by way of an air pressure fan, the fan impeller of which is fixed without any additional drive to the common turbine shaft between exhaust turbine and charge air turbine and rotates with the turbine shaft (n= 1,000,000 rpm), so that, for identical cooling rates, the cooling system with air pressure fan cooling can be designed with smaller dimensions than a cooling system with airstream cooling, thereby leading to fuel saving.

Patent DE-3326648-A1 (DE)
Title: Catheter with adjustable front nozzle and balloon
Inventor: SCHUBERT WERNER DR MED
IPC: A61F2/958
Filed: 1983-07-23
Abstract: A new type of catheter is proposed with an adjustable front nozzle 1 and at the same time with a balloon 4 especially for dilation in vessels or other pathways of the human or animal body. The catheter has one lumen, so that the width of the catheter lumen is improved over the entire length, which is favourable for passage of fluid and transmission of pressure effects and pressure pulses. The important feature is the adjustability of the front nozzle 1 by the conical closure body 9 which is connected to the rear by the holding wire 8 until the nozzle 1 is completely closed, it also being possible for the nozzle to become an axis for a shaft with fittings, such as a cutting tool 14, which then necessitates a more lateral position of the front nozzle, and also for injections in pathways of the body or for suction of body fluids such as blood which may also contain detritus, scraped off tissue material from constricted arteriosclerotic vessel(s) after the use of the cutting tool. <IMAGE>
Patent DE-3330208-A1 (DE)
Title: Component consisting of a valve housing and water meter
Inventor: MAAG HORST C
IPC: G01F15/18
Filed: 1983-08-20
Abstract: A component consisting of a valve housing and a water meter is proposed in order to be able to determine the consumption of hot and cold water in dwellings. Up to now, it has been possible for water meters to be combined only with valve housings of shut-off valves which are such that between their connecting stubs a horizontal valve seat is provided on which an internal tube, arranged in a support tube of the water meter that can be screwed on to the valve housing, can be supported with its free end. The invention now renders it possible for the valve housing of a free-flow valve, which has between its connecting stubs only one circular cylindrical recess, extending at right angles to said stubs, for accommodating a valve member which can be adjusted axially by, for example, rotating it, also to be combined with a water meter. This is achieved by assigning to the end of the internal tube, which is located in the installed state of the water meter in the cylindrical recess of the valve housing, a water-diverting member through which, on the one hand, a connection is formed between one connecting stub and an annular duct of the water meter defined by the support tube and internal tube and, on the other hand, a connection is formed between the internal tube and the other connecting stub.
Patent DE-3330958-A1 (DE)
Title: Device for switching over a daisywheel in typewriters or similar office machines
Inventor: KITTEL ARTHUR ING GRAD
IPC: B41J1/24
Filed: 1983-08-27
Abstract: In order to be able to accommodate the large supply of characters on daisywheels required in modern typewriters, printers have been developed, in which two types are arranged on a single stem in each case in the radial direction of the stem of the daisywheel. In this case, a switch-over device is required for switching over to the desired row of types. The invention is based on the object of providing a switch-over device for a daisywheel (13) with two rows of types arranged concentrically, which device requires little drive output and allows the daisywheel (13) to be switched over rapidly and with little noise in the simplest possible manner. This object is achieved in that the rotary adjustment shaft (11) is arranged with the daisywheel (13) and the drive motor (25) on a swivel bearing (27) which can be swivelled about an axis of rotation (29). This axis of rotation (29) lies in the vicinity of the point of intersection of the horizontal plane associated with the inclined faces of the types (17, 19) and the vertical plane defined by the centre of gravity of the mass to be switched over. The switch-over device according to the invention is simple and inexpensive in construction and operates with little noise. <IMAGE>

Title: Assembly method with robot
Inventor: KAISER LOTHAR
IPC: B23P21/00
Filed: 1983-09-20
Abstract: The method is used for assembly of workpieces comprising a plurality of parts using a robot 5. The latter removes the parts in a predetermined sequence from trays (12). The trays (12) with the various parts are transported in a predetermined sequence on at least one transport path (10) to a removal point (23) next to the robot (5). Here, the parts are taken hold of one after the other by the gripper arm (21) of the robot and taken altogether to the assembly area, where they are joined together. By co-ordination of the movements of the robot gripper arm and supplying the trays with the parts, the distance to be travelled by the gripper arm can be kept very short, which means that the robot is used in an economical fashion. <IMAGE>

Title: Hydroponic greening element
Inventor: HAERTLING FRANZ DIPL ING
IPC: A01G31/02
Filed: 1983-11-14
Abstract: The invention relates to a hydroponic greening element in particular for noise-protection walls in front of motorways, industrial installations and the like. It offers for the first time a greening element which, in the normal sequence of climatic events, meets its water requirement exclusively by natural precipitation and in the case of suitable plant cultivation, e.g. certain varieties of polygonum, requires no maintenance for years. Greening elements according to the invention can be arranged above one another in a storeyed manner on a noise-protection wall and then together use the natural precipitation, all upper and lower greening elements constantly having specifically the same water quantity available in their reservoirs. The water distribution takes place exclusively by means of force of gravity. Without regard for the position of the uppermost greening elements, the water supply remains pressureless; leaks cannot occur. Each greening element can be arranged longitudinally axially in the centre of the noise-protection wall and then greens the noise-protection wall both towards the noise source (motorway etc.) and towards the housing development to be protected, without a noise bridge arising as a result. <IMAGE>
