Title: Drive connection to the front wheels of an agricultural tractor
Inventor: MARSCHALL HANS
IPC: B60K17/22
Filed: 1983-09-01
Abstract: A drive connection to the front wheels of an agricultural tractor is described which contains a propshaft connecting the manual transmission to the differential gear accommodated in the front axle beam. The propshaft is enclosed by a protective tube in order to prevent grass and straw from coiling round it, which tube has such a small outside diameter that the ground clearance of the agricultural tractor and the lock angle of the front wheels is not restricted compared to conventional drive connections without a protective tube. The small outside diameter of the protective tube is obtained in that the idler shaft of the propshaft is reduced to that diameter which is absolutely essential for transmission of the torque. For stepping up of the critical whirling speed of the propshaft, the idler shaft is supported by way of an anti-friction bearing approximately in the middle of the protective tube. The protective tube is supported on the front axle beam side and transmission side by way of spherical and slide joints directly on the front axle beam and/or the transmission or by way of antifriction bearings arranged in the vicinity of the joint on the intermediate shaft. <IMAGE>

Title: Device for the operation of a fluid-flow turbo machine
Inventor: FLASKAMP HEINRICH
IPC: F03B13/00
Filed: 1984-04-11
Abstract: For the operation of fluid-flow turbo machines in power station installations, a natural reservoir is required, from which water can be drawn and fed to the turbo machine. Such conditions are to be encountered only at quite specific locations so that steam turbines with a poorer efficiency had to be switched to. In the device according to the invention at least three tanks 2, 3, 4 of the same volume are inserted between the feed and drainage line 5, 6 of a fluid-flow turbo machine 1. For the continuous operation of the fluid-flow turbo machine one tank including the feed and drainage line, and the fluid-flow turbo machine itself are filled with fluid. Each tank 2, 3, 4, 13 is controlled by fittings for the feed and drainage of the fluid. In addition, each tank is also provided with two connections for the admission of a pressure medium to the fluid and for its removal. The tanks are connected in series in a ring system so that whilst the pressure medium is being admitted to a tank a second tank is being filled with fluid flowing out of the turbo machine 1, the pressure medium simultaneously flowing out of the remaining tanks. <IMAGE>

Abstract: In order to produce a perforated tube, a process is disclosed in which, on a mandrel having a multiplicity of projections arranged at intervals, strips arranged at an angle with respect to one another are wound such that they lie between the projections. The strips together delimit openings through which the projections extend. The strips consist of fibres impregnated with a curable resin or plastics material, the plastics material and fibres together forming a tube which can withstand a pressure of at least 4136 kPa. Since projections are provided on the mandrel, the fibres can be impregnated so that they have a high resin content. The openings can be covered with grains with a low resin content to form a sieve, the grains being provided in a dome-like geometry. Spaces lying below and/or above a set of the strips and caused by the other strips are filled with a synthetic resin which can contain a sand filler. <IMAGE>
Patent DE-3430221-A1 (DE)
Title: Gas turbine with intake pipes
Inventor: ZEMANN HERBERT
IPC: F02C3/32
Filed: 1984-08-17
Abstract: In the gas turbine with intake pipes an attempt is made to reduce the thermal stressing of the turbine blades by cooling the gas jet without significantly impairing the efficiency of the turbine. For this purpose the gas jet is directed over a cone and along the ends of intake pipes. The entrained air cools the gas jet and increases the gases striking the turbine blades. The suction generated produces a stronger air flow, which by way of a turbine wheel drives the compressor and by way of cooling fins cools the combustion chamber. <IMAGE>

Title: Method for a dial-up PBX system which is fitted with an operational terminal
Inventor: VERLOHR AXEL DIPL ING
IPC: H04Q3/62
Filed: 1984-09-13
Abstract: In a memory-programmed dial-up PBX system (NA) whose subscriber stations are in each case assigned to one of a plurality of subscriber classes, the enabling or disabling of a traffic relation is determined by the contents of a stored table (T) to which the control processor unit (2St) refers. Individual sub-domains of this table are permanently allocated to a specific traffic type for an internal or external traffic relation. The authorisation or barring for the traffic relation from an originating station (T1) to a destination station (A1) can be determined for the individual sub-domains independently of one another by operational inputs (BT) and can be modified at any time during operation. If the originating station is a forwarding line or a forwarding line group, such as an exchange line group (A1), and the destination station is a subscriber station (T1) of a predetermined subscriber class and vice versa, access for the direct incoming and outgoing traffic and the authorisation for the acceptance or transfer of a traffic link received and set up by a different subscriber station (VPL) can be configured via the classification in the individual sub-domains (TB1-TB3) of the stored table independently of one another in a flexible, subscriber-individual manner. In the case of a plurality of exchange line groups, the authorisation for the specified traffic types ... for each ... Original abstract incomplete. <IMAGE>

Title: Seat with shock absorber for motor vehicles
Inventor: PETER OSKAR E
IPC: B60N2/52
Filed: 1984-12-01
Abstract: In a known seat with a shock absorber for motor vehicles according to US Patent 2993732, the seat frames of the vehicle are provided with hydraulically actuated damping securing devices, consisting of pistons, cylinders and pipes, in order to protect the passengers from serious injuries in the event of a collision or sudden braking of the motor vehicle, since the seat belts alone are not sufficient. These hydraulic securing devices have many components, are complicated and expensive to manufacture. A substantial disadvantage of the oil damper devices is their susceptibility to faults during operation. Small oil losses put the ability of the system to function at risk, and continuous maintenance of the hydraulic securing devices is also necessary. In addition, in the event of a collision of the motor vehicle it is the case that the oil lines suddenly leak and thus the securing device does not operate. The disadvantages of the shock absorber using the hydraulic system for seats of motor vehicles according to the US patent are eliminated according to the invention by means of an annular spring shock absorber consisting of enclosed inner and outer rings with corresponding conical faces, which shock absorber is arranged horizontally under the seat. In the event of the motor vehicles being involved in a collision, the inner and outer rings move over their conical faces in the direction of travel, the kinetic energy being considerably reduced and damped by friction on the conical faces with a reduced ...
