Patent DE-3421757-A1 (DE)
Title: Tin-free steel of excellent weldability, and method for the production thereof
Inventor: SHIMIZU NOBUYOSHI
IPC: C25D5/12
Filed: 1984-06-12
Abstract: The invention relates to a tin-free steel with a triple coating comprising a base layer of chromium metal, an interlayer of a nickel-zinc alloy having a zinc content of from 10 to 90% by weight, and a top coat of chromium oxide hydrate on a base steel, and a process for the continuous production of this tin-free steel which comprises:   (1) chromium plating of a base steel to produce a layer of chromium metal and chromium oxide hydrate, (2) nickel-zinc alloy plating of the chromium-plated base steel, using a nickel-zinc alloy-plating electrolyte which is sufficiently acidic to dissolve the chromium oxide hydrate and (3) generating a chromium oxide hydrate layer on the chromium-plated nickel-zinc-plated base steel. Instead of process step (2) it is also possible to carry out cathodic treatment in an acidic solution to remove the chromium oxide hydrate produced during the chromium plating and then to carry out the nickel-zinc alloy plating using a conventional nickel-zinc alloy plating electrolyte. The surface-treated steel sheet according to the invention is suitable for high-speed production of welded can bodies without removing the plated layer in the welded area, as it has excellent weldability.
Patent DE-3423305-A1 (DE)
Title: Variable watercraft
Inventor: PFEIFFER JOHANNES
IPC: B63B1/14
Filed: 1984-06-23
Abstract: The hitherto known variable watercraft are without exception converted by means of movable cross members from the single-hull state into the multi-hull state and vice versa. However, movable cross members raise the problem of strength in particular in larger watercraft. Solution: the problem is solved by a watercraft which has a rigid connecting system instead of movable cross members. The buoyancy bodies are arranged below this system in such a way as to be rotatable about their vertical axis or are arranged so as to be rotatable and displaceable in the direction of the longitudinal axis of the rigid connecting system. The simplified principle of conversion exclusively by means of rotation of the buoyancy bodies about their vertical axis enables buoyancy bodies to be arranged in pairs, which lie one behind the other in the single-hull state and parallel to one another in the multi-hull state. <IMAGE>

Title: Ink cartridge for an inking apparatus for multicolour printing on a recording medium
Inventor: JOHANNSEN FRED DIPL ING
IPC: B41J2/175
Filed: 1984-06-30
Abstract: Inking apparatuses for multicolour printing on recording media likewise require exchangeable ink cartridges (5) and devices to display the end of the ink in good time. The invention is based on the object of providing ink cartridges having a plurality of ink containers which contain different colours of ink, which ink cartridges are simple to produce and assemble and guarantee a reliable flow of ink to the print head. For this purpose, three small bags of ink (8, 9 and 10) are mounted on the bottom (15) of the housing (7), while a large bag of ink (11) containing black ink rests on said small bags of ink. Due to the increase in pressure thus caused in the small bags of ink (8, 9 and 10) arranged on a lower level, an approximately equal pressure is achieved in all the outlet apertures of the bags of ink (8, 9, 10 and 11). The display of the end of the ink in one of the bags of ink (8, 9, 10 and 11) takes place via a measurement of the capacity between the nonwoven guide plates (44 and 51) and the variable ink volumes in the bags of ink (8, 9, 10 and 11). <IMAGE>

Title: Apparatus for storing waste gas in refuse dumps
Inventor: SCHNEIDER REINHARD
IPC: B09B1/00
Filed: 1984-07-13
Abstract: The invention relates to an apparatus for storing the decomposition gases formed in refuse dumps, which permits the installation of even very large gas accumulators at almost any point in or near the refuse dump, using structurally simple and cost-effective means. According to the invention, the gas accumulator is situated underground, the excess pressure prevailing in the container being absorbed by the earth surrounding the container on all sides. The accumulator is filled with a large volume of refuse which forms cavities, on the one hand absorbs the external pressure exerted by the earth and on the other hand provides the cavity necessary for the storage of gas. The impermeability of the container is guaranteed by means of a gas-impermeable coating, e.g. a plastic film, on all sides. The invention also describes a method for producing such an underground storage container.

Patent DE-3440019-A1 (DE)
Title: Fluidically operated brake device, in particular for working cylinders
Inventor: SCHNEIDER GOTTFRIED PROF DR SC
IPC: F15B15/26
Filed: 1984-11-02
Abstract: The invention can mainly be used in high-pressure pneumatics in the pressure range of 0.4-1.5 MPa. It can be used where sequencies of motion of working cylinders are to be fixed and braked at predetermined points. Such demands are made in particular on modern automatic machines, equipment and industrial manipulating appliances in which large controllable forces are to be transmitted analogously or virtually analogously in minimum working strokes under complicated conditions. The special demands imposed in the field of application also result in the object of creating a fluidically operated brake device which can be used in the area of high-pressure pneumatics and which brings the brake elements directly into effect at the working piston with little design complexity. This is achieved by virtue of the fact that a brake element on the one side, which can be acted upon fluidically, is arranged in the interior of a cylinder and/or on the piston and/or on the piston rod of the cylinder, and that the brake element on the other side is also arranged outside the hydraulic cylinder and is coupled to the piston rod. The brake device can be designed as a brake tongue basket or as an elastic tube.

Title: Process and device for press forming glass objects
Inventor: FUJII SHIGEZO
IPC: C03B11/02
Filed: 1984-12-20
Abstract: The invention relates to a process and a device for press forming glass objects, in which a specific number of press moulds is arranged with uniform spacing on an intermittently rotatable turntable and on the circumference thereof, a feedstock is fed from a feedstock feeding device during the stoppage of the intermittent rotary movement of the turntable and in which the feedstock is compression moulded with the aid of a press plunger. The invention is characterised in that the residence times due to the intermittent rotary movement of the turntable (R) represent a repetition of alternately long and short time periods, the short residence time corresponding to the time necessary to feed feedstock into a press mould (M) and the long residence time corresponding to the time necessary to mould the glass objects with the aid of press plungers; in that the arrangement is designed such that with each stoppage of the turntable (R) a feedstock is charged directly into a press mould in drops and in that during the long residence time the press plungers are actuated in order to mould a number of glass objects simultaneously. <IMAGE>
Patent DE-3500397-A1 (DE)
Title: Electric percussion drilling machine
Inventor: ANDO HIROYUKI
IPC: B23B45/16
Filed: 1985-01-08
Abstract: The electric percussion drilling machine comprises a rotatably mounted drill holder (20), a drive member (58) to which a reciprocating movement is imparted, and an electric motor (2) which simultaneously sets the drill holder (20) in rotation and applies the reciprocating movement to the drive member (58). Arranged at an axial distance from the drive member (58) is a percussion hammer (60) which transmits blows to the drill holder (20) when the latter rotates in the one direction. A helical spring (59) is arranged between the percussion hammer (60) and the drive member (58) in such a way that it is expanded and compressed in accordance with the reciprocating movement of the drive member (58) and thus produces a prestress which presses the percussion hammer (60) in the direction of the percussion movement. Accordingly, the helical spring (59) transmits the energy of the reciprocating drive member (58) to the percussion hammer (60) and the drill (23) without an additional connecting medium, such as, for instance, an air cushion. In this way, the efficiency of transmission is improved and a powerful percussion action with low power consumption is obtained. <IMAGE>

Patent DE-3512281-A1 (DE)
Inventor: REGAR KARL-NIKOLAUS DR
IPC: F02D23/00
Filed: 1985-04-03
Abstract: An internal combustion engine may be driven in the suction mode as well as the supercharging mode. Switchover from the suction to the supercharging mode takes place with the accelerator pedal in a switchover position, and switchback to the suction mode is effected in the return switching position of the accelerator pedal. The switchover and switchback positions are offset with respect to each other with the accelerator pedal in a central position between its initial position and its final position. The arrangement is such that the switchover position is reached at the end of the suction mode at fully open throttle flap (full power position). Upon switchover the throttling of the supercharging flow (throttling begin position) is increased as compared to the end of the suction mode. This throttling of the supercharging is diminished by further actuation of the accelerator pedal in the direction of the final position. Corresponding switchback from the supercharging to the suction mode takes place when the accelerator pedal is in the switchback position at which the drive of the supercharger established by the engine shaft is interrupted and a change is made from the stronger throttling during the supercharging mode to the weaker throttling in the suction mode.

Patent DE-3527028-A1 (DE)
Title: Spiral-casing pump
Inventor: HOLZENBERGER KURT DR
IPC: F04D29/60
Filed: 1985-07-27
Abstract: The invention relates to an arrangement of a spiral-casing pump having standardized dimensions on an appertaining standardized base plate, four bores below the spiral casing being provided for fixing the latter and two bores below the drive-side pump shaft bearing being provided for fixing a support foot. Instead of the bearing flange previously used in standard construction spiral-casing pumps the invention provides for a conventional bearing block to be fastened on the base plate by its legs at the two bores in the region of the drive-side pump bearing shaft and at two of the bores closest to these below the spiral casing. As a result, the advantage present in the bearing flange, of simple removal of the pump rotor from its casing, is transferred to the conventional bearing block, which is advantageous in terms of the pump rotor position in the casing being unaffected by the internal pressure of the casing and by the forces acting on the piping, without the drawbacks of the elements hitherto used as alternatives to one another being incurred.
Patent DE-3530437-A1 (DE)
Title: Aerostatic bearing, in particular for exhaust turbochargers
Inventor: TITTIZER GABRIEL DIPL ING
IPC: F01D25/22
Filed: 1985-08-26
Abstract: The present invention relates to an improved aerostatic bearing with radial and axial guidance. The use of denser surface layers (8, 9, 10) which restrict the emergence of gas through the gas outlet surfaces (2b, 3b, 4b), makes possible complex bearing shapes which permit simultaneous radial and axial support for a shaft (1). Corresponding complementary guide surfaces (2a, 3a, 4a) of the shaft (1) lie opposite the gas outlet surfaces. The angled shape of the bearing gaps (5, 6, 7) requires additional gas outlet paths (14, 15, 16, 17, 18, 19) to ensure that the dynamic properties of the bearing are not impaired. <IMAGE>
