Patent DE-3432784-A1 (DE)
Title: Process for electrodeposition of a hard gold plating for electronic purposes
Inventor: SZEKELY FERENC
IPC: C25D3/62
Filed: 1984-09-06
Abstract: The invention relates to a process for producing a shiny hard gold plating comprising a cobalt alloy by electrodeposition from an acidic galvanic electrolyte. According to the invention, electroplating is effected from an electrolyte comprising 0.02-0.08 mol/l of potassium dicyanoaurate, 0.02-0.9 mol/l of potassium dihydrogen phosphate, 0.1-0.7 mol/l of citric acid, 0.01-0.1 mol/l of cobalt(II) salt, 0.01-0.6 mol/l of nitrilotriacetic acid, 0.02-2.0 g/l of sodium salicylate, 0.01-1.0 g/l of poly(vinylpyrrolidone) and 0.1-8.0 ml/l of additive, in the pH range of 3.5-6.5 with a current density of 0.1-3.0 A/dm<2> and at a temperature of 15-80 DEG C. The additive used is the 2-8% by weight aqueous solution of the reaction product of 0.8-1.2 mol of epichlorohydrin, 2 mol of  alpha , omega -diamino-n-alkane of the general formula H2N-(CH2)n-NH2, where n is an integer between 2 and 6 and 1 mol of hydrocarbon halogen-substituted in the  alpha , omega -position, of the general formula X-(CH2)n-X, where X is a chlorine or bromine atom and n is an integer between 2 and 8. The major advantage of the process according to the invention is constituted by the fact that the process can be used to coat even steel alloys having high chromium/nickel contents, that the plating time, owing to the unusually high current density which can be employed and the high current utilisation, can be considerably reduced, and that mould formation on the electrolyte solution can be eliminated.

Title: Outlet valve for fuel pump
Inventor: TUCKEY CHARLES H
IPC: F02M59/46
Filed: 1984-11-12
Abstract: An outlet valve for electrically operated fuel pumps is disclosed which has a valve element having a conical nose section which merges into a spherical region for resting on a valve seating. Axially extending ribs on the valve element form shoulders for a valve spring constructed as a helical spring and, in addition, ensure that the fuel flow can flow inside the spring so that the flow is not impaired by the degree of compression of the valve spring. <IMAGE>
Patent DE-3443554-A1 (DE)
Title: Rotating mechanical seal arrangement
Inventor: JANSSEN DIETER
IPC: F16J15/40
Filed: 1984-11-29
Abstract: A rotating mechanical seal arrangement with an internal pump is designed as a seal based on a sealing medium in that the pump is designed as a positive displacement pump and the space which adjoins the rotating mechanical seal and accommodates the sealing medium under pressure is connected to a liquid drain passage which contains a flow resistance element, in particular a pressure-relief valve which can be set to a pressure above the pressure to be sealed off. On the side of the pump remote from the rotating mechanical seal, a low pressure is established, allowing the arrangement to be sealed off on this side by means of a simpler seal. The use of this arrangement is advantageous particularly in connection with the sealing of shafts of centrifugal pumps, the pressure of which rises more slowly at a low speed than that of the pump contained in the seal arrangement.

Title: Pleat belt for curtains, draperies or the like
Inventor: KRUCKENBERG KLAUS
IPC: A47H13/16
Filed: 1984-12-21
Abstract: A pleat belt (1) for curtains (17), draperies or the like has a pair of pull cords (6, 7) for automatically pleating the curtain (17), which pair of pull cords has floating sections (10, 11) lying on the window side in the region of each belt pleat (8, 9) to be formed and is guided on the belt (1) in each case between groups of belt pleats (8, 9) to be formed. The pleat belt (1) is to be improved in respect of the decorative appearance, the complexity of sewing it onto the curtain (17) and the pleat formation, the intention also being to reliably rule out distortion of the curtain or drapery material. Furthermore, there should also be a large variation range in the decorative design in association with inexpensive manufacture. For this purpose, the pleat belt (1) is sewn together from two layers (2, 3), an outer backing layer (2) arranged on the window side containing the pull cords (6, 7) and consisting of a stiff fabric, and the inner facing layer (3) arranged on the room side being designed as a decorative border, and the outer backing layer (2) of the pleat belt (1) has an edge strip (18) located below the two pull cords (6, 7) for sewing on the curtain (17) on the window side. <IMAGE>

Patent DE-3525806-A1 (DE)
Inventor: ZIMMER ERNST
IPC: B25J9/00
Filed: 1985-07-19
Abstract: The invention is a further development of the gear-head unit for a manipulator described in German Open Patent Application No. 34 28 748. In order to increase the radius of action and range of applicability of the gear-head unit a structural arrangement with three concentric drive axes and four allowed rotational motions of front, intermediate and rear segments of the manipulator is set forth. These front, intermediate and rear segments are pivotally mounted together about first and second inclined pivot axes which are inclined to each other and to the main drive shaft axis. Along these inclined pivot axes two hollow drive shafts connected with each other extend which are supported by reduction gears in the front and/or intermediate segments. Because of that simultaneous opposing rotational motions of the intermediate and rear segments can be obtained from a single drive motor. In the rear segment an output drive shaft attached to a front plate for a tool holder is rotatably mounted which is driven by coupled intermediate drive shafts guided through the hollow drive shafts.

Patent DE-3604031-A1 (DE)
Title: Thermostatically controlled regulating valve, in particular for hot water heating systems
Inventor: KASPRIK MANFRED
IPC: F16K31/64
Filed: 1986-02-08
Abstract: The thermostatically controlled regulating valve has a housing which consists essentially of three branches arranged in a T shape, one of the branches accommodating the adjusting elements of the valve. The significant adjusting elements of the valve are a closing piece, which is carried by the spindle and interacts with the valve seat, and a presetting body which coaxially surrounds the closing piece. During the closure of the valve, the valve spindle, which is operated by a thermostatic element, is displaced axially counter to the force of a compression spring. As seen from the valve seat, this compression spring is clamped between a flange of the valve spindle and a fixedly mounted disc or shoulder, above the presetting sleeve.
Patent DE-3609312-A1 (DE)
Title: Centrifugal pump
Inventor: HOFFMANN HANS
IPC: F04D7/04
Filed: 1986-03-20
Abstract: The invention relates to a centrifugal pump for delivering enriched or contaminated liquids with lumpy or fibrous solid portions, with a pump housing which forms an annular duct and is provided with an axial inlet, an impeller which is mounted therein and flowed through essentially radially, and a cutting attachment consisting of fixed and rotating cutters for comminuting the solid portions in the liquid. As pumps of this kind, it is in particular liquid manure pumps which are in use, which have the aim of homogenising the fibrous dirty liquid which has become peaty. According to the invention, the impeller is on the suction side formed into a cylindrical annular body, in which essentially radially inwardly directed cutter bodies are fastened on the inner circumference, while the pump housing has a cylindrical annular attachment, in which at least one radially inwardly directed cutter body is mounted on the inner circumference. As a result of doing away with rotating rotationally symmetrical parts in the pump inlet, the known twist formation of fibrous components is completely avoided. <IMAGE>
