Title: Addressing method and arrangement for virtual storage
Inventor: WEYDE WOLFGANG DIPL ING
IPC: G06F12/08
Filed: 1982-12-24
Abstract: In the principle of virtual storage, the number of accesses to the background memory should be as small as possible since such accesses are very time consuming. However, the number of accesses depends on the page length, that is to say on the quantity of the data which are coherently transmitted during an access. To adapt this page length dynamically in an optimum manner even in the case of different programs and other boundary conditions, the accesses to the background memory are counted in in each case fixed time intervals and when a threshold value is exceeded during this process, the page length is changed by a factor. During this process, it is also continuously monitored whether the number of accesses changes compared with the preceding time interval. If the current number of accesses has risen, the page length has therefore been changed in the wrong direction and the direction of change is reversed. The page length is suitably halved or doubled with each change. The threshold value can be changed in dependence on how many times in succession the page length is changed. <IMAGE>

Title: Device for driving a gallery, tunnel or the like by pipe-advancing operation, in particular for producing an inaccessible pipeline
Inventor: HINRICHSEN GERHARD
IPC: E21B7/20
Filed: 1982-02-10
Abstract: In a device for driving a gallery, tunnel or the like by pipe-advancing operation with a driving shield, in particular for producing an inaccessible pipeline, having a working chamber defined at the front by the face and a drilling head which works in a rotary manner in this working chamber and has drilling tools for working the ground material in sight at the face, the drilling head (8) is surrounded by a hood (20) which encloses the working chamber in such a way as to extend the driving shield and close it off towards the face. The hood (20) has apertures (24) for the passage of the drilling tools (18). Furthermore, tools (47) for working the ground in a scraping or cutting manner are provided on the hood (20). The hood (20) is axially displaceable relative to the drilling head (8). This enables the scraping tools (47) and the drilling tools (18), e.g. as hard-rock drilling tools, to be alternatively used separately from one another or together for working the ground so that any ground formations, even with embedded erratic blocks of hard rock, can be driven through without having to exchange tools. <IMAGE>

Patent DE-3306389-A1 (DE)
Title: Rotating-piston internal combustion engine with a sliding-vane compressor
Inventor: MUELLER WALDEMAR
IPC: F01C1/344
Filed: 1983-02-24
Abstract: Rotating-piston internal combustion engine, the advantages of which consist in the fact that combustion energy is converted without a crank drive etc. into direct, vibrationless rotation, lead-free fuels being used. This is an engine which performs a virtually complete power stroke for each rotation of the piston, while the working cycles of induction, compression and expulsion take place at the same time. Due to the spiral shape of the displacer space, which tapers in the direction of rotation, the expansion pressure acts for a prolonged period on the rotor, which, due to spring pressure, is always moved remotely from the axis, and is expelled with little noise. In addition to the displacement pressure, there is, due to the outflow of the expansion pressure out of the combustion space in the rotor and injection nozzles into the displacer space, a reaction effect in the direction of rotation by virtue of jet energy, with a large possible pivoting angle. Valves, gas exchange and ignition timing are eliminated since these tasks are performed by rotating piston and slide overdrive, making lead additives in the fuel unnecessary. Counter to the direction of rotation, the displacer space is shut off by a sealing strip which revolves without leaving a gap and always rests sealingly on the rotating piston at the cylinder nose.
Patent DE-3307126-A1 (DE)
Title: Process and devices for the continuous and three-point measurement of very small differential pressures
Inventor: ESDORN HORST PROF DR ING
IPC: G01L11/00
Filed: 1983-03-01
Abstract: The invention relates to a process, by means of which very small differential pressures, such as are employed, for example, for maintaining pressure in rooms by means of air-conditioning systems, can be measured without any mechanically moved parts. The measurement principle is based on the fact that heat or another marking substance is fed to the gas or liquid stream flowing as a result of the pressure difference, and that its effect, namely an increase in temperature or concentration, is used as a measurement signal. For a device calibratable in units of pressure, either the heat supplied or the stream of marking substance or the increase in temperature or concentration must be kept constant. In one case, the increase in temperature or concentration serves as a measured quantity, in the other case the heat supplied or the stream of marking substance supplied. The abovementioned conditions lapse in the event, often sufficient for maintaining pressure in rooms, that only the direction of the pressure difference is to be established or ensured by regulation. The advantages of the process are that, especially when used for three-point measurement or control, a reliably working and wear-free measuring device for checking that pressure is being maintained, for example in operating theatres, animal-breeding laboratories and the like, can be provided at a very low outlay.

Patent DE-3318457-A1 (DE)
Title: Elevating working deck with a working platform arranged on an articulated mast
Inventor: RAUEN JOHANNES DIPL ING
IPC: B66F17/00
Filed: 1983-05-20
Abstract: The subject matter of the application relates to an elevating working deck with a working platform arranged on the top arm of an articulated mast, consisting of two or more arms, and held horizontally via a levelling device. The arms of the articulated mast can be raised via electro-hydraulically controlled hydraulic cylinders, and the permissible raising angle of the top arm relative to the horizontal or erecting plane is limited by an operating limit switch dependent upon inclination. An emergency limit switch dependent upon inclination is arranged downstream of the operating limit switch. The emergency limit switch responds if the permissible raising angle of the top arm is exceeded. In such an elevating working deck, automatic lowering of the top arm by a negligible fraction of the raising angle is now to be provided when approaching a limit switch in the raised end position, so that, upon reaching the permissible raising angle of the top arm in each case, in the event of lowering of the bottom arm as a result of a hydraulic defect the top arm is also gradually lowered independently before the emergency limit switch completely cuts off the control of the apparatus. To this end, an additional valve is arranged on the hydraulic cylinder of the top arm. When the operating limit switch or an inclination switch in synchronism with it responds, the additional valve opens and releases the return flow of the hydraulic medium from the hydraulic cylinder of the top arm for a certain time interval.
Patent DE-3325551-A1 (DE)
Title: Method for identifying a device
Inventor: PUETTER PAUL STEFAN DIPL PHYS
IPC: H04L29/06
Filed: 1983-07-15
Abstract: There are numerous applications in which a connection is set up between a device G and a system or a different device A and in which it is important for A to know the identity of G. The object of the invention is to make it substantially more difficult for G to establish unauthorised contact with A. For this purpose, modifiable information is stored in G which is used for identification. This information used for identification can be modified every time that contact is established. If a foreign device gains unauthorised access to the information used to identify G, the consequences depend on the order in which contacts are established. If G is used before the foreign device, the latter's authorisation is cancelled. If the foreign device is used first, A no longer acknowledges the authorisation of G, whereby misuse can be detected. Fields of application include videotex and other types of remote data processing via dial-up telephone lines in public or private networks. A further field of application is mobile radiotelephony traffic.

Abstract: A pneumatic shock absorber, especially for road vehicles. The rolling bellows of the shock absorber is made of a simple hose body which has no end beads, and is mounted with the aid of metal clamping rings on vehicle parts which are cushioned relative to one another. To simplify mounting, the mounting regions of these parts are provided with reduced-diameter engagement surfaces. To improve this mounting system, the support piston which is associated with the lower end portion of the rolling bellows is provided with circumferential ribs which are disposed in at least one axial portion of the reduced-diameter mounting region thereof. These circumferential ribs preferably have a triangular cross-sectional shape. The frictional mounting is thus supplemented and reinforced in a simple manner by a positive connection, so that the rolling bellows is reliably secured relative to every disadvantageous axial movement.
