Title: Adjustable lumbar support for a backrest
Inventor: GMEINER GUENTER DIPL ING
IPC: A47C7/46
Filed: 1988-05-19
Abstract: An adjustable lumbar support for a backrest is proposed, consisting of a supporting plate which is pivotably received by a spring clip, is movable in the sense of a change in the supporting action via a first adjusting device acting on the spring clip pivotable about a bearing arrangement with approximately vertical axis, and is movable with regard to the changing of the height position of the supporting action by means of a second adjusting device assigned both spatially and functionally to the first adjusting device. To obtain a simple, space-saving height adjustment, the bearing arrangement is pivotable about an approximately horizontally running axis and is operatively connected to the second adjusting device. Assigned to both adjusting devices is a common driving member which can be brought into engagement selectively with one or other of the adjusting devices by means of a displacement movement.

Title: Valve for the pharmaceutical industry, particularly for biotechnology
Inventor: SCHLEICHER KARL DIPL ING
IPC: F16K3/28
Filed: 1988-06-04
Abstract: The invention relates to a valve for the pharmaceutical industry which consists essentially of a valve housing, an operating spindle and a rubber-elastic sealing diaphragm. The intention is to improve a valve of this kind in such a way that it guarantees a hermetic seal in relation to the outside air and also allows the throughflow cross-section to empty. This is achieved by virtue of the fact that the throughflow cross-section (16) of the valve housing (2) is designed so as to be free from ribs, grooves or the like over its entire length and that the diaphragm (5) sealing off the valve housing (2) hermetically from the outside has, on its side facing away from the operating spindle (4), an integrally formed plug-like projection (6) matched to the sealing contours of the valve housing (2) as a shut-off element. <IMAGE>

Title: Method and arrangement of a sensor for multidimensional movement and vibration, preferably in the case of low signal strength
Inventor: NEUSEL ROLF
IPC: G01D5/28
Filed: 1988-07-26
Abstract: Multidimensional sensor having an inertial mass composed, for example, of a mercury pearl (bead, pellet, dot) on to which the measured variable of the movement or vibration is coupled through the base (substrate) of said pearl. Since the curvature and location of the surface are determined only by surface tension and gravity, there is extreme accuracy of reproduction. A light beam is used to interrogate the reflection of suitable points of the surface, and the light signals are passed on by means of known methods, converted into electric signals and evaluated using known methods to produce signals for direction, intensity, and frequency and rate of the movement or vibration. The simple design permits integration in the cable for the purpose of avoiding the sources of error in plugs (connectors).

Title: Method for producing electrical printed circuit boards
Inventor: GENZER JOHANN
IPC: H05K3/00
Filed: 1988-09-29
Abstract: A covering layer which is applied to a printed circuit board and can be activated photochemically is washed off by means of a solvent. After this, until now, the printed circuit board has been sprayed with water in order to remove solvent residues. At the same time, a portion of the solvent, which is hazardous to the environment, was dissolved in the water. According to the invention, the solvent is now blown completely off the printed circuit board by means of a directed air flow, the contamination of the water being avoided.

Patent DE-3916121-A1 (DE)
Title: Light source for an optical communications system
Inventor: IWASAKI YOSHIKI
IPC: H04B10/11
Filed: 1989-05-18
Abstract: A light source for an optical communications system generally contains a plurality of lighting devices (D1 to Dn) which are, for example, light-emitting diodes (LEDs). The lighting devices (D1 to Dn) arranged next to one another are passed through by an intermittently flowing current and therefore produce, on emitting optical signals, electromagnetic radiation. In order to reduce this electromagnetic interference, current passes through two neighbouring devices (D1, D2; D3, D4; ...; Dn-1, Dn) in each case in mutually opposite directions (A, B). The lighting devices can form a straight-line or circular arrangement. <IMAGE>

Patent DE-3918421-A1 (DE)
Title: String for rackets, especially tennis or squash rackets
Inventor: GRABOSCH REINHOLD DR
IPC: A63B51/02
Filed: 1989-06-06
Abstract: When a racket is strung with a large number of individual strings, coupling parts have to be affixed to the ends of the individual strings and, in turn, capable of being fixed into corresponding receiving parts on the racket frame. The new stringing is intended to permit better retention of the coupling parts on the ends of the individual strings. This is achieved in that the individual strings of the stringing each have a grooved surface and the grooving in each case extends helically on the string in question. The effect of the use of a helical design of the grooving is that, despite grooving, virtually no weakening of the material takes place on the string in question. <IMAGE>

Title: Backflow weir sewer system main duct - has hinged flap held in incoming or on-going line above water at normal level by floating counterweight
Inventor: FRIGGER MARTIN DIPL ING
IPC: E03F5/12
Filed: 1989-11-13
Abstract: The backflow weir for the outlet from a drain system etc.  into an outfall, flowing at right angles to it, allows unrestricted flow into the outfall at normal water level by a hinged flap (5) which shuts at high water. The flap is so mounted in the drain system that at normal water level it is above the  cross-sectional area through which flow takes place. A separated control shaft (11) is connected (12) to the outfall (4) at high water. The shaft contains a counterweight (10) coupled to the hinge spindle (6) of the flap. Water, entering the shaft at high water, causes the counterweight to float upwards so that it no longer counterbalances the weight of the flap, which swings down into the pipe. ADVANTAGE - No need for floor height differences, and no slurry and dirt deposition.

Title: Electroless copper plating - using bath stabilised by combination of alkali metal cyanide with thiourea and/or poly:butane-1,4-diol mercaptan(s)
Inventor: KOEHLER ULRICH DR
IPC: C23C18/40
Filed: 1989-11-21
Abstract: The novel feature in the prodn. of Cu-plated mouldings by electroless plating from an aq.-alkaline bath contg. a Cu salt, a redn. agent, a complex former and a stabiliser is that the stabiliser is a mixt. of (a) an alkali metal cyanide with (b) thiourea and/or a polybutane-1,4-diol-omega, omega-bismercaptan of formula HS-(A1-O)p-(CH2)4 -O-((CH2)4-O)m-(CH2)4 -(O-A2)q(O-(CH2)4)nSH (I) where A1 and A2 = 1,2-alkylene with 2-4C; m and n = 0-50; and p and q = 0-50. Also claimed is (I) where at least one of p and q is not O and its prepn. by block polymerisation of THF with alkylene oxides followed by conversion of the terminal OH gps. to SH gps. by known methods.

Patent DE-4009911-A1 (DE)
Title: Cutting soft webs of material - by two=dimensional oscillation of outer blade
Inventor: SPIEGELMACHER KURT DIPL ING
IPC: B23D49/16
Filed: 1990-03-28
Abstract: When soft webs of textile material, paper, plastic foil, fibre mats or food have to be cut by an oscillating prim.  motion in the vertical plane, this is coupled to a secondary pendulum motion at right angles to it and superimpqsed on the primary motion. At a steady rate of advance this results in a slower forward motion of the cutting edge or even a brief reversal at the two top and bottom dead centres. ADVANTAGE - This prevents any undesirable wrinkling of the material at the top and bottom dead centres of the oscillating primary motion, where otherwise the 'pulling' mode of cutting would preponderate over the beneficial 'drawing' mode, so that the quality of the cut is improved.
