Patent DE-3339584-A1 (DE)
Title: Device for improving the transfer of heat and material on evaporator heating surfaces and expulsion surfaces
Inventor: LEINER WOLFGANG DR ING
IPC: F28F13/02
Filed: 1983-11-02
Abstract: A device for improving the transfer of heat and material on evaporator heating surfaces and expulsion surfaces is proposed, which makes use of the favourable influence of the poor wettability of specific materials in bubble boiling. Poor wettability occurs when the wetting angle between the solid body of the device (fibres, fabrics, spun yarns, nonwovens, lattices, perforated plates or the like) and the liquid to be evaporated is (measured in the liquid) greater than 60 DEG . Meshes and/or cutouts are provided in order to prevent steam cushions, which inhibit heat transfer. As a consequence of the wet effect, additional components of the device, which can be effectively wetted, can be used to transport liquid to the parts of the heating surface covered by steam cushions. A reduction in the required superheating of a heating surface by such a device to a tenth of the original value has been observed in conjunction with the same heat flux density. The device is not directly a component of the heating surface, and can therefore be mounted subsequently and easily be exchanged.

Title: Device for producing photographic contact prints of a multiplicity of framed slides
Inventor: SCHEUREN KARL HEINZ
IPC: G03B27/04
Filed: 1983-11-25
Abstract: In a device for producing photographic contact prints from a multiplicity of framed slides of a miniature film on a common sheet of photosensitive material, what is important is optimum utilisation of the copying area of this photosensitive material. For this purpose, the windows in the individual retaining frames provided for accommodating the framed slides are to be situated at a distance from one another such as gives rise to a type of arrangement of the framed slides in which the short rectangle sides of the rectangular slide image area point in the direction of the course of the sequence. Specifically, in this case because of the dimensioning of the mounts, which abut one another in this case, a space shielded against light and corresponding to the size of a unidirectional image area is produced between adjacent slides.

Inventor: SCHAUF HERBERT
IPC: E06B3/677
Filed: 1984-01-24
Abstract: The invention relates to a process for producing an insulating glazing consisting of at least two panes, in which the panes are washed, brought into their final position with respect to one another by interposing a surrounding spacer covered with a sealing material and in which the assembly is pressed with the application of pressure, the arrangement is introduced into a chamber and there the pane interspace is filled with a special gas and then the insulating glazing thus formed is sealed with an adhesive. To achieve reliable filling, at least one filling hole (37) is provided in the spacer and the assembly (24) thus formed is first evacuated either before or after the sealing after pressing in a vacuum chamber (21) and then flooded with the special gas. Subsequently the filling hole (37) is sealed and the insulating glazing or the region thereof around the filling hole (37) is sealed. Alternatively, before pressing, the assembly is evacuated in the vacuum chamber (21), feeding a gap between a pane (2) and the spacer, and subsequently flooded with the special gas. Subsequently the pressing and sealing are carried out. A polyisobutylene is used as sealant or a thio-elastomer as adhesive. <IMAGE>

Title: Device for the topping-up of brake fluid
Inventor: BURCKHARDT MANFRED DR ING
IPC: B60T8/44
Filed: 1984-02-07
Abstract: In the context of an antilock system functioning on the outflow principle for a dual-circuit brake system of a motor vehicle, a top-up device is provided which throughout pressure reduction phases of the ABS control provides for the topping-up of brake fluid in the tandem master cylinder of the brake system. A topping-up valve is provided for each brake circuit, which valves in their open positions each connect one of the outlet pressure chambers of the tandem master cylinder to an accumulator constantly maintained at a high outlet pressure, which accumulator can be charged from the brake fluid reservoir. The topping-up valves are separately or jointly switched into their open position at least as long as a pressure reduction phase of the ABS control is under way on at least one of the wheel brakes of the respectively assigned brake circuit. The flow factors of the pressure reduction flow paths leading to the reservoir by way of the brake pressure control valves and of the top-up flow paths leading by way of the topping-up valves are so designed by virtue of the construction of these valves that, per unit time, at least that quantity of brake fluid is topped up which flows back into the reservoir during a pressure reduction phase.

Title: Circuit arrangement for connecting telephone stations to a line concentrator system
Inventor: BRANDSTETTER ALFRED DIPL ING
IPC: H04M1/738
Filed: 1984-02-21
Abstract: The invention relates to the connection of telephone stations to line concentrator systems. The object is to create a current path on the station side with simple means which has low impedance for the identification current of the system when the handset is lifted and which has high impedance when full feed current is applied. This is achieved through the intermediate connection of two first, opposite-pole, series-connected self-blocking FETs between the a/b wires. The FETs are through-connected in the quiescent condition by a long-life voltage source via a further FET which blocks when full feed current is applied. A further fourth FET switches negative potential obtained from the system feed in telephone station operating mode to the gates of the first FETs so that the latter block.

Title: Semiconductor memory
Inventor: SATO MASAYUKI
IPC: H01L21/8242
Filed: 1984-11-22
Abstract: A semiconductor memory formed on a substrate has a read amplifier, a memory cell and an auxiliary cell. Each of these cells contains a capacitor and a switch for connecting the capacitor to the read amplifier. Each capacitor is configured by so-called trench-capacitor technology. All trench capacitors are identically designed. Since the number of trench capacitors which are connected in parallel in the memory cell is twice the number of trench capacitors which are connected in parallel in the auxiliary cell, the capacitance of the auxiliary cell can very easily be exactly set such that it is half that of the memory cell.

Patent DE-3513365-A1 (DE)
Title: Method and device for limiting switching-on currents
Inventor: ZIERHUT HERMANN DIPL ING
IPC: H05B39/02
Filed: 1985-04-15
Abstract: In the case of the method for limiting a switching-on current when a load is being connected to an electrical network, two suitably formed voltages are compared and current pulses are passed to a current gate, which current pulses gradually open said current gate during the switching-on process. In consequence, overcurrents during the switching-on process are prevented, as can occur when the initial internal impedance of the load is still low, as a result of cold incandescent elements and heating wires, when lamps or heating elements are connected to the electrical network. Circuit arrangements for carrying out the method are specified. The method and the circuit arrangement which operates in accordance with the method are particularly suitable for mass production, for domestic use, as a result of the physically small dimensions and the extremely cost-effective production capabilities.
Patent DE-3515367-A1 (DE)
Title: Method and device for delivering bulk material from a container
Inventor: STEGNER MATHIAS
IPC: B65D90/62
Filed: 1985-04-27
Abstract: For the metered delivery of bulk material from a container (1), a metering body (6) carries out continuous lifting movements in the container outlet (2). In order to interrupt the discharge of bulk material from the container completely, the metering body (6) is lowered through a substantially cylindrical outlet shaft (10) down to an inwardly projecting annular sealing seat (11). The metering body (6) carrying out the metering movement thus serves simultaneously as a closure body. This results in a simple construction with a low constructional height (drawing). <IMAGE>
Patent DE-3516541-A1 (DE)
Title: Tool holder
Inventor: KALTENECKER JOHANN
IPC: B25D17/08
Filed: 1985-05-08
Abstract: A tool holder for coupling tools to hand machine tools is proposed, in which the tool shaft (9) is received in a coupling sleeve (6) which has a cage (13) with, contained therein, axially parallel slots (12), in which locking bodies (11) in the form of balls are contained, which engage in recesses (10) of the tool shaft (9) for axial locking. The coupling sleeve (6) is surrounded by a sliding sleeve (7) which is coupled to the inner cage (13) via coupling pins (16) to form a unit which is displaceable relative to the coupling sleeve (6). Situated inside the coupling sleeve (6) as axially parallel radial control surfaces (19-21) are inner annular surfaces which are stepped in the axial direction and have increasingly large radial spacings. These interact with the locking bodies (11) for locking and unlocking. By axially parallel displacement of the locking bodies (11) via the sliding sleeve (7), the locking bodies (11) can yield radially and release the tool shaft (9) and conversely they can move inwards radially for locking (Fig. 1). <IMAGE>

Title: Device for positioning and turning an element
Inventor: LOEVENICH JOHANN
IPC: G21C19/20
Filed: 1985-05-10
Abstract: The invention relates to a device for positioning and turning an element, consisting of a specimen or a capsule with a specimen, in a vertically aligned channel, such as an irradiation channel of a nuclear reactor. The aim is a device which can be used even if only a narrow channel is available for inserting the element. This object is achieved when there are provided inside an external tube coaxially guided pipe lengths of different diameter, of which those bearing on one another in each case can be displaced inside one another and in the stretched condition engage inside one another with their adjacent ends in a self-closed fashion. In this arrangement, a rotary drive acts on the uppermost pipe length, while the lowermost pipe length can be connected to the element in a self-closed fashion. Furthermore, extending inside the pipe lengths is a tensioning element which acts on the element and by means of which the element can be pulled up by telescoping the pipe lengths.
