Title: Process for the continuous production of low-fluoride pentoxides of tantalum or niobium
Inventor: BAUER GUENTER J
IPC: C01G33/00
Filed: 1984-08-04
Abstract: A process is described for the production of low-fluoride pentoxides of tantalum or niobium. To carry out the process, an acidic tantalum or niobium solution having a concentration of 50-250 g/l of tantalum oxide or niobium oxide is passed into a reactor at a flow rate of 50-300 kg/m<3>.h of tantalum oxide or niobium oxide. The concentrations of the reaction components in the overall solution are matched in such a way that the precipitation of the oxides takes place completely during the residence time in the reactor. To this end, the reaction component streams are matched, as a function of the flow rate of the overall amount of liquid in the reactor, in such a way that in the suspension discharged from the reactor a pH results which corresponds to the formula  pH = k + D . tg alpha . In this formula, D represents the flow rate of the overall amount of liquid through the reactor, k is an element-dependent constant according to Figure 1, and  alpha  is the slope of the two curves shown in Figure 1. When carrying out the process, the reaction volume in the reactor is kept constant. <IMAGE>

Title: Process for cleaning a weld pool
Inventor: BODE HANS DR ING
IPC: B23K9/16
Filed: 1984-09-17
Abstract: For welding work, in particular build-up welding, which requires a high purity of the material introduced, it is proposed to add calcium and/or calcium compounds to the weld pool and to subject the protective gas atmosphere covering the weld pool to a superatmospheric pressure that exceeds the vapour pressure of the calcium at the melting point of the base material. In this way the contents of undesirable impurities such as oxygen, sulphur, arsenic, antimony, tin, phosphorus, nitrogen, lead and bismuth can be greatly reduced, whereas desired contents of chromium, nickel, manganese and silicon remain almost unaffected.

Patent DE-3513297-A1 (DE)
Inventor: RUCKERT HEINZ-JUERGEN
IPC: F16K1/34
Filed: 1985-04-13
Abstract: The invention relates to a shut-off valve with a soft-sealing valve cone which can be moved by a valve spindle, the valve cone having metallic supports above and below its soft-sealing part, which come to rest in a conical valve seat when the shut-off valve is closed, a spring element abutting onto the soft-sealing part resulting in the soft-sealing part being pressed against the valve seat on further movement of the valve spindle in the closing direction, because of the deformation of the spring element. A complete chambering of the soft-sealing part during the deformation process is achieved according to the invention in that the support (7) located underneath the soft-sealing part (2) is formed by a rigid plate (4) covering the end face of the soft-sealing part (2), and in that an elastic sprung plate (3) is arranged independently of the support (8) above the soft-sealing part (2), which plate (3) is to be deformed by the end face of the valve spindle (10) which moves further after abutment of the supports (7, 8).
Patent DE-3515407-A1 (DE)
Inventor: HAEHNKE MANFRED DR
IPC: D06P3/66
Filed: 1985-04-29
Abstract: In a known isothermal dyeing process, the alkali required for fixing the dye is added linearly or progressively to the neutral dyebath under program control. In this process, the amount of alkali added per unit time is initially small and increases progressively in accordance with a preprogrammed profile. This involves passing through a certain (uncontrollable) initial phase until fixation of the dye starts on the cellulose. Subsequently, the rate of fixation attains a maximum and then gradually ceases, to arrive at the final state of the dyeing. To shorten the initial phase (delay time) of dye fixation and in order to slow down the rate of fixation during the steepest part of the curve, it has been found to be advantageous to add the alkali according to a parabolic program.

Title: Bottle opener for removing bottle closures shaped like champagne corks
Inventor: RUHNKE JUERGEN DIPL ING
IPC: B67B7/06
Filed: 1985-06-26
Abstract: The object of the invention is to open in a controlled and safe fashion bottles which are under internal pressure and are sealed by means of pressed-in bottle closures shaped like a typical champagne cork, i.e. which have a bead which projects beyond the bottle neck. According to the invention, the object is achieved in that the bead of the pressed-in bottle closure projecting beyond the bottle neck is inserted into an appropriate shaped part and the glass bead on the bottle neck is enclosed by a semi-circular ring. Initially, the closure is firmly seated in the bottle neck. Then the shaped part is moved towards the spindle axis by displacement of the spindle, the closure being pulled out of the bottle. The pressure in the bottle then causes the closure to be pressed against the shaped part, and the closure can then be removed from the bottle in a controlled and safe fashion by further displacement of the spindle. <IMAGE>
Patent DE-3523608-A1 (DE)
Title: Method and apparatus for bending metal sheets into a round shape, particularly for can bodies
Inventor: WEIL WOLFGANG
IPC: A63G13/08
Filed: 1985-07-02
Abstract: Flat rectangular metal sheets (10) are moved between a driven bending roll (32) and a supporting roll (34) and are bent around the bending roll (32) by these and by a plurality of pressure rolls (52, 56) arranged behind the supporting roll. The sheet (10), bent almost completely into a round shape is bent away elastically from the bending roll (32) by a deflecting body (62), the front edge (10a) of the sheet thereby being prevented from reentering the gap between the bending roll (32) and the supporting roll (34) before the rear edge (10b) of the sheet has passed through this gap. The deflecting body (62) is then moved back into its rest position, with the result that the forward area of the sheet (10) springs back towards the bending roll (32) and is thereby grasped by the bending roll (32) and supporting roll (34) again and moved between them. When the front edge (10a) of the sheet (10) has reached the interspace between the two last pressure rolls (56), all the pressure rolls (52, 56) are raised and the sheet (10) is turned by the bending roll (52) until its front edge (10a) is gripped firmly by catching levers (68). The sheet (10) bent into a round shape is now stripped axially from the bending roll (32). <IMAGE>

Title: Sound-insulating wall element, in particular for doors
Inventor: ZOESCHINGER THEODOR
IPC: E06B5/20
Filed: 1985-09-06
Abstract: For a sound-insulating wall element (1) disclosed in DE-OS 3315559 and consisting of pressboard panels, the invention relates to the problem of achieving, in addition to the high sound insulation, a high-strength edge reinforcement for fastening edge fittings such that break-in is prevented. For this purpose, the aim of the invention is to provide, on the inner side of the individual door shell (2, 3) which is provided with groove-shaped cutouts (6) and is located in the longitudinal, solid-walled edge regions (4), in each case one continuous channel (9, 10) for receiving suitable reinforcing strips (11, 12) consisting of solid material, e.g. hardwood laminate. The distance (13) of these channels (9, 10) from the outer edge (14) of the door leaf (2, 3) corresponds to the amount by which the unfinished door shell is greater than the finished format of the door shell (2, 3). When machining the edges of the door shells (2, 3) which are adhesively bonded to one another and form a wall element (1), the reinforcing strips (11, 12) appear in the rebate (15), it being recommended to arrange the reinforcing strips (11, 12) offset with respect to each other in correspondence with the rebate depth. <IMAGE>

Title: Device for monitoring the ink supply in ink jet printing units
Inventor: HENTSCH KARIN DIPL PHYS
IPC: B41J2/175
Filed: 1985-09-13
Abstract: The invention relates to a device for monitoring the ink supply in ink jet printing units, the prime object of which device is to realise a fluid level display which, without adverse effects on the ink, is as independent as possible of the ink parameters and of fluctuations in the ink level which vary as a function of time and temperature. The object of the invention is therefore to develop a monitoring device which, whilst utilising the stable property of extinction, permits a contactless, continuous monitoring of the fluid level of the ink reservoir container and detects the absence of the reservoir container. According to the invention, for this purpose an optical barrier is arranged perpendicularly or approximately perpendicularly to the ink reservoir container in such a way that the said barrier penetrates the transparent ink reservoir container and is interrupted when the said container is filled with printing fluid, it being possible to distinguish between the receding of the printing fluid in the ink reservoir container and the absence of the ink reservoir container as a function of the strength of illumination. The invention can be applied in ink jet printing units of typewriters, printers or similar machines which use inks with a low degree of extinction, in particular however when using inks with a high degree of extinction.

Title: Pneumatic cylinder with infinitely adjustable stroke and end-position damping acting on both sides
IPC: F15B15/24
Filed: 1985-11-14
Abstract: The combining of a pneumatic cylinder, a hydraulic shock absorber acting on both sides, a stroke-adjusting device and end-position sensing to form a construction unit. A reciprocating pneumatic cylinder (1) - see Fig. 1 - in each case carries the damping piston (2) with it before reaching its end positions. The damping piston (2) plunges into oil-filled bushes (3) or (4). A decreasing "annular gap" (5) produces a damping action. Adjustment of the cylinder stroke by turning the adjusting part (6) and resulting displacement of the nut (7) on the threaded rod (8). A control pin (34) attached at right angles to the damping piston (2) - see Fig. 7 - permits end-position sensing of the pneumatic cylinder (1) by sensing the end positions of the damping piston (2). The advantage of the device according to the invention, through the combination of several functions to form a construction unit, lies in a substantial reduction in the cost of production and the constructional effort during installation, in the development of new ranges of application and in the simpler operation and maintenance in practical use. <IMAGE>

Title: Mechanical programming aid as a compact unit having time switching mechanisms which have a programming switching disc fitted with switching riders
Inventor: NOETZOLD NORBERT
IPC: H01H43/06
Filed: 1986-02-20
Abstract: The invention relates to the extended possibility of being able to operate mechanically displaceable switching riders on a programming switching disc of time switching mechanisms without any problems, even with dimensionally constrained separations. In this case, the invention provides an alternative. This lever, which is supported concentrically on the switching disc and such that it can rotate about said switching disc has a joint at the level of the switching rider movement plane, which joint makes it possible to bend this lever, which ends in a handle, at this point in order (by means of a specially shaped pressure part) to move in each case one switching rider into the switching position, and to move it back by opposite bending of the handle. This invention is intended to provide protection for this concentrically guided captive lever, irrespective of which movement is used to achieve the switching rider displacement. This block invention is likewise intended to provide protection for the fact that the number of switching riders can be doubled in order to halve the time of the switching intervals.
