Title: Seal for a displacement machine
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C19/08
Filed: 1987-10-16
Abstract: A seal for a displacement machine for compressible media is described. The displacement machine has in this case at least one displacement chamber arranged in a stationary housing and designed in the manner of a spirally running slot, and in each case a strip-like displacement body assigned to and engaging in each displacement chamber and likewise of spiral-shaped design which is held on a disc-shaped rotor which can be driven eccentrically in relation to the housing. For sealing the axial gaps remaining between the stationary housing and the rotating rotor, spiral-shaped sealing strips (8, 9) are provided, which are in each case held in a recess (15) which is arranged on an end-side web edge of one component (5) and runs in the circumferential direction, and are pressed by resiliently elastic means (18) against a sealing surface (10) arranged on the end side of the other component (2a). In order to reduce the expenditure for the manufacture of the recesses receiving the sealing strips, each recess (15) is to be open radially inwards, in other words towards the centre of the sprial, and the spiral-shaped sealing strip (8) is to be held in this recess under radially outwardly directed prestress. To this end, the ends of each spiral-shaped sealing strip (8) can be connected non-positively and/or positively to the respective component (5) having the recess. <IMAGE>

Patent DE-3737894-A1 (DE)
Title: Propeller having adjustable blades (variable pitch propeller)
Inventor: LUTZ FERDINAND DR
IPC: B64C11/30
Filed: 1987-11-07
Abstract: In the case of adjustable propellers, for example for aircraft, the propeller blade is rotated about the blade axis during flight when the airspeed changes. A change in the airspeed necessarily results in the incidence angle of the air relative to the plane of the propeller blade changing. The aim of rotating the propeller blade about the blade axis is to prevent the incidence angle of the propeller blade at the same time changing with disadvantageous results. In the case of adjustable propellers of the known type, the incidence angle is, however, stabilised only for a small section on the propeller blade. The adjustable propeller according to the invention in contrast makes it possible to stabilise the incidence angle over the entire propeller blade (1), with the advantageous consequence of less noise being developed, and greater thrust. The propeller according to the invention enables differential blade twisting (warping) at different angles between the blade root (2) and the blade tip (3). Propeller as a vehicle drive element, primarily for aircraft. <IMAGE>
Patent DE-3738644-A1 (DE)
Title: Digital circuit arrangement
Inventor: SIGHART HERBERT
IPC: G06F11/20
Filed: 1987-11-13
Abstract: Very high requirements must particularly be placed on the operational reliability of digital circuits if a disturbance arising herein leads to a failure of the higher system. Fulfilling this requirement by a redundant construction of critical circuit parts causes a considerably increased expenditure in power consumption and components. Furthermore, such a redundant construction has the disadvantage that, on the occurrence of a disturbance in the switch-over logic between two redundant circuit parts, failure of the system in the case of a disturbance can nevertheless not be avoided. It is proposed to realise a flexible, fully redundant system which minimises the circuit expenditure and space requirement by carrying out the digital circuit arrangement by means of special integrated components (LCAs), i.e. so-called "logic cell arrays", to which is assigned an operating function safety circuit (BFS) with the aid of which, within the framework of disturbances detected within the framework of test routines, these disturbances can automatically be eliminated by substitute circuit configuration of the components involved. <IMAGE>

Patent DE-3828595-A1 (DE)
Inventor: MEISCHEN GEROLD
IPC: H02G1/06
Filed: 1988-08-23
Abstract: For ploughing cables, a corresponding laying plough (18) has a cable chute (26) serving to guide the cable (10 ... 12). When only one cable is laid, a relatively narrow cable chute can be used, the clear width of which is slightly greater than the diameter of the cable. To lay a plurality of cables next to one another, the cable chute (26) would need to be of correspondingly wide dimensions, which requires an increased traction outlay for the laying plough (18) and a greater mound in the ground. The object of the invention is to permit the laying of a plurality of cables (10, 11, 12) without the abovementioned disadvantages. The process according to the invention provides that the cables (10 ... 12) are guided behind or above one another in a common vertical plane through the cable chute (26), and are only re-oriented shortly before the cables (10 ... 12) emerge from the cable chute (26). For this, the laying plough (18) according to the invention has a specially designed cable chute (26). The invention is particularly suitable for burying cables (10 ... 12) in sand, but also for burying other objects in sand which are to be laid in the ground (17), for example pipes, tubes or the like. <IMAGE>
