Title: Differential pressure measurement system ascertaining ships speed - has single-unit dynamic and static pressure chambers with common membrane
Inventor: NIEGEL DIETER
IPC: G01L13/02
Filed: 1980-01-11
Abstract: A pressure measurement system, esp. for differential pressure speed measurement units of ships, has an arrangement of measurement channels for static and dynamic pressure connected to a differential pressure measurement device. Signal variations caused by wave motions are compensated without increasing indication lag or degrading accuracy. Each measurement channel feeds through a membrane pressure cell whose pressure chamber (1) is bounded by a membrane (10). The chambers are combined into a single unit. They may be bounded by a common membrane subjected to the static pressure on one side and the dynamic pressure on the other. This arrangement ensures that the immersion pressure esp. when the arrangement is used in a submarine does not destroy the membrane. Slow dynamic pressure increases affecting the static system via the membrane are dissipated via the inlet.

Title: Play free guide for moving carriage - is of sheet metal with groove along flange for hardened and ground steel rod
Inventor: JENKNER ERWIN
IPC: E01B25/24
Filed: 1980-01-29
Abstract: The guide for a feed carriage as in the main patent is made from sheet material (1) bent into a trough shape, and has a return flange (7) at one end. The other end (2) has a bent over limb extending a short distance towards the return flange. This limb has a V shaped groove (3) along it, open towards the interior. Secured inside this groove is a rod (4), and the carriage travels on wheels which roll on the rod. Counter pressure rollers travel on the outside corner of the groove, so that there is minimum play. The rod is made from hardened and ground steel.
Patent DE-3005886-A1 (DE)
Title: Steel tube for transporting solid materials, esp. sand and gravel - where heat treatment is used to form martensite in tube bore, and tough outer zone of ferrite and pearlite
IPC: C21D9/14
Filed: 1980-02-16
Abstract: The tube is fed continuously through a hardening plant for zone heating from the bore of the tube, so a zone extending through the entire tube wall thickness is converted to austenite (AG). Brief external quenching of tube is then used to form martensite, after which the retained heat in the tube converts the martensite to an outer layer of ferrite and pearlite. The bore of tube is next briefly quenched to form martensite. Both brief quenching operations are pref. for max. 2 seconds, while the conversion of the outer martensite to layer by the retained heat pref. lasts min. 5 secs. The bore of the tube resists wear by sand and gravel in the excavation industry, but the tube has a tough outer skin, so it is not brittle.

IPC: B66C23/34
Filed: 1981-02-07
Abstract: In a folding crane with a telescopic mast (7, 8) pivotable about a horizontal axis and a jib (13) linked to the free end of the telescopic mast (7, 8), a common capstan (17) in power-transmitting connection with the mast telescoping mechanism is provided for swivelling the mast (7, 8) and the jib (13). So that the crane can be raised and lowered with preselectable angular positions of crane mast and jib relative to one another, two power-transmission units leading from a reversible capstan (17) to the mast (7, 8) or to the jib (13) are arranged in such a way that, during rotation of the capstan (17), one unit is hauled in and the other unit is slackened, that the power-transmission unit leading to the mast (7, 8) is connected to the telescoping mechanism for the mast parts (7, 8) which can be locked against one another or is a part of this mechanism, this mechanism having the same motion-transmitting transmission ratio as the power-transmission unit (18, 19, 20) provided for swivelling the jib (13), and that the two power-transmission units are set up in such a way that their transmission ratio relative to one another can be individually selected. <IMAGE>

Title: Apparatus for the bundling and tying of tubes
Inventor: AENGENEYNDT WOLF DIPL ING
IPC: B65B27/10
Filed: 1981-04-24
Abstract: The invention relates to an apparatus for the bundling and tying of elongate articles, especially tubes and rods, which are lifted out of a collecting trough, shaped to form parcels and, tied by tying means, transported further to a collecting point. In order to save means of transport and transport stations, whilst ensuring the least possible transport delay, the tube bundles are extracted from the collecting trough by means of a tong manipulator which, simultaneously with the transport function, by means of a truss former integrated into its gripper tongs, carries out the shaping of the tube bundles to form a solid parcel and carries this parcel in a stepped longitudinal movement past a tying machine which, after each step, moves into the tube bundle and ties it with a tying means, after which the tong manipulator deposits the finished tube parcel for transfer to a collecting device.
Patent DE-3117467-A1 (DE)
Title: Tent structure
Inventor: BEHREND RUEDIGER
IPC: E04H15/32
Filed: 1981-05-02
Abstract: In a tent structure, the roof skin (2) of which is cut out at the edge in the shape of an arch, in which an edge rope (7) running along the cut line is connected at its ends to ground anchors (3), and which has an apron which can be inserted into the opening (4) formed by the roof-skin cutout, the aim is to provide a constructional simplification, an improvement to the access to the interior space of the tent and a possibility of opening and closing the openings (4) more quickly. For this purpose, it is proposed that there be attached to the apron at least one tensioning rope (8, 9) which extends in the shape of an arch from one ground anchor (3) of the associated edge rope (7) to the other and is likewise connected to these ground anchors (3). The tensioning rope (8, 9) can be fastened to the ground anchor (3) with interposition of a tension spring (15) or can be designed to be particularly extensible. The tensioning rope (9) can also be attached to the apron by means of an elastic tying means (12). A single tensioning rope can be guided over at least one deflection pulley (14) and thereby forms two arch-shaped tensioning-rope portions (8 and 9). <IMAGE>

Title: Model circuit of a salient-pole machine
Inventor: BLASCHKE FELIX DIPL ING DR
IPC: H02P/
Filed: 1981-05-25
Abstract: A circuit arrangement (9') uses entered values for the stator current (i@), rotor resistance (R<L>) and an inductance parameter which is allocated to the main inductance of the machine, corresponds to a fictional non-salient pole machine (cylindrical rotor machine) and is preferably selected to be equal to the quadrature-axis inductance (xq) of the actual salient-pole machine, and an entered, fictional excitation (energising) current value (i@) to determine a flux (magnitude  psi , space vector  phi L). The fictional excitation current value can be calculated in a computation element (7') from a predetermined flux ( psi *), the stator current (i@) and the inductance parameter (xq) of the fictional non-salient pole machine and can be compensated for, in order to take into account the salient nature of the actual machine, in an output stage (8') using a disturbance variable <IMAGE> from the direct-axis inductance (xd), the quadrature-axis inductance (xq) and the model flux and its rotor-related direct-axis component ( psi d =  psi  . cos psi L) in order to determine the excitation current (i<E*>) associated with the predetermined flux ( psi *) (Fig. 6). In a reversed manner, if the true excitation current (i<E*>) is preset, the fictional excitation current can also be formed by use of this disturbance variable and the model flux can be determined in the circuit arrangement (95) as the value of the flux associated with the true excitation current. <IMAGE>

Title: Pressure-resistant container for materials capable of flow
Inventor: GERHARD HELMUT DIPL KFM
IPC: F17C1/00
Filed: 1981-07-01
Abstract: A pressure-resistant container for materials capable of flow, especially a liquefied gas tank for motor vehicles, consists of two (or more) parallel cylindrical tubular shells, one tubular shell being of fully cylindrical design, and, with its part situated within the container, forming a partition wall with openings to connect the two chambers of the container. The use of a fully cylindrical tube with just a few openings imparts to the container a high strength for a low volume weight. The use of tubular shells of different lengths and correspondingly shaped end walls allows full use to be made of the space available, often trapezoidal, in a motor vehicle. <IMAGE>
