Title: Self-closing mixing fitting for sanitary installations
Inventor: DENKENA KARL-HEINZ DIPL ING
IPC: F16K21/04
Filed: 1986-06-26
Abstract: A description is given of a self-closing fitting for sanitary installations, in which a self-closing valve is combined with a mixing device. This device has two inlet connections (3, 4) for cold and hot water and an outlet 2 for the mixed water. The ratio of the quantities of water fed in via the inlet connections can be controlled by means of a rotatable control sleeve (6). Arranged coaxially in the control sleeve is the self-closing valve, which is provided with a back-pressure chamber (17) that can be emptied via an auxiliary valve (16). The first inlet connection (3) is connected to a pressure-carrying feed line, while the second inlet connection (5), which opens into a direct connection (13) to the outlet, is connected to the outlet of an unpressurised reservoir (water heater). An outlet connection (4) separated from the first inlet connection by the main valve (15) of the self-closing valve is connected to the inlet of the unpressurised reservoir. Downstream of the main valve in the direction of flow of the cold water, the control sleeve is designed as a valve element of a 3-way valve, the inlet of which is connected to the main valve and the outlets of which, the cross-section of passage of which can be varied, are connected, on the one hand, to the outlet connection and, on the other hand, to the outlet. <IMAGE>

Title: Gripping mechanism
Inventor: TISCHER SIEGMAR
IPC: B65H5/12
Filed: 1986-09-11
Abstract: The invention relates to a gripping mechanism for pulling out the bottom-most sheet of paper in a flat stack in machines for the further processing of sheets. The aim of the invention is to develop a gripping mechanism having a gripper which exerts as much pressure as possible, with simultaneous reduction of spikes. To achieve this, a gripping mechanism is to be devised which does not bring about any increase in spring resistance when the gripper is opened. According to the invention this is brought about by arranging the articulation points for the resilient elements on a movably mounted lever with a cam roller and by making the said roller rest against a further cam plate, the maximum eccentricity "e2" of which is arranged so as to be offset with respect to the maximum eccentricity "e1" of the cam plate which interacts with the linkage. <IMAGE>

Title: Shift register adder circuit in 54321 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-10-01
Abstract: The shift register adder circuit according to the subject of the invention has a main circuit which consists of eight or nine simple flipflops. If a possible carry is processed using a one-upwards shift circuit (4), the main circuit consists of only eight simple flipflops. The summand at the A inputs is input with reversed value grading into the corresponding flipflops, so that the flipflops which are set to high potential also form a closed column. The value 5 is also processed using a dual full adder (5). If the shift register partial sum is greater than 4, it is reduced in circuit (3) or (3b) by the number 5, and to compensate, the dual full adder (5) is triggered with high potential at its input (i). <IMAGE>

Title: Method for producing an ultrasonic transducer array
Inventor: SACHS BERTRAM
IPC: H04R17/00
Filed: 1987-11-19
Abstract: In ultrasonic transducer arrays, the piezoceramic ultrasonic transducers 6 of which are spatially separated from one another by separating grooves 8 having an approximately trapezoidal cross-sectional area, the acoustic cross-coupling between the individual ultrasonic transducers 6 is advantageously reduced. According to the invention, it is proposed to produce the separating grooves 8 in each case by a number of sawing cuts of different cutting width and cutting depth, which are oriented perpendicularly to the flat side 5 and extend in a common cutting plane 10. Such a production method is a technically simple process and the trapezoidal shape of the cross-sectional areas of the separating grooves can be approximated sufficiently well in few steps. <IMAGE>

Title: Method and device for detecting structures of a surface of a planar item (article)
Inventor: HERDEN ANDREAS DIPL PHYS
IPC: G01N21/88
Filed: 1988-04-29
Abstract: A method and a device for detecting structures of a surface (13) of a planar item (12), in particular glass panes, is specified. A coherent light beam (2) is projected onto the surface (13) and components (14) of the light which are produced by beam diffraction on structures of the surface (13) are detected and investigated. It is possible to proceed from this to judge the presence or absence of specific structures. In one device, the coherent light beam (2) is focused onto a reflective coating (8) on a substrate (6) which is otherwise non-reflective and light-transmitting, and is deflected by said coating, and the reflected beam is projected via a lens (9) onto the surface (13) of the item (12) which is to be investigated. Without disturbance by a structure, the reflection takes place in such a way that focusing occurs on the coating (8). Components (14) of light which are produced by beam diffraction on structures penetrate the substrate (6) outside the coating (8) and can be projected by means of a positive (collective, converging) lens (15) onto a detector (16) and evaluated there. The mode of procedure is suitable, in particular, in assessing abrasion resistance of, or the abrasion-induced damage to, coated surfaces, in particular surfaces having thin-film coatings and/or in assessing desired or undesired unevennesses of an otherwise flat surface. <IMAGE>

Title: Coupling for fluid lines
Inventor: WEH ERWIN
IPC: F16L29/00
Filed: 1988-05-05
Abstract: For the simple operation and high degree of safety in the case of a coupling for pressurised fluids, it is proposed to arrange an inlet valve, a venting valve and an outlet valve in the housing of the coupling and to switch the inlet valve and the venting valve alternately into the open position by an actuating device, e.g. an eccentric shaft. By virtue of this alternate locking of the valves, at least one valve is always closed, even when operated by a non-specialist, with the result that no fluid can escape under pressure. Said coupling is thus suitable, in particular, for pressure refuelling in petrol stations, since an extremely high degree of safety and simple single-handed operation are achieved.

Abstract: The invention relates to a reflectometer for the examination of optical waveguides (11) having an optical receiver (15) to which the light back-scattered in the optical waveguide (11) is fed and whose output (20) is fed to the input (30) of an amplifier (31) connected downstream, and relates also to a method for the examination of an optical waveguide (11) by means of the reflectometer. In this case, the influence of Fresnel reflections arising at fault locations is intended to be suppressed and the most accurate examination possible is to be made possible in the direct vicinity of fault locations. For this purpose, at least one electric switch (42) is provided, by which the output (20) of the optical receiver (15) and the input (30) of the amplifier (31) connected downstream can be connected to a reference point at a predetermined potential. By means of capacitive crosstalk effects, an additional interference signal is generated on operating the switch (42), which signal is compensated with the aid of a compensation circuit (50). Furthermore, the useful signal is freed of influences as a result of the storage effect of the optical receiver (15). By means of repeated closing of the switch (42) during a measuring process, a plurality of Fresnel reflections can be blanked out (masking). Examination of optical waveguides. <IMAGE>
