Title: Rotary evaporator
IPC: B01D3/08
Filed: 1986-12-02
Abstract: A rotary evaporator having a rotary drive for an evaporator flask is provided with a vapour throughflow tube (8), passing through the drive region, one end of which tube faces the evaporator flask and the other end of which faces the condenser. The drive connection to the evaporator flask (3) is carried out by a rotary driven drive sleeve (11) via a driver (12). The vapour throughflow tube (8) engages uncoupled into this drive sleeve (11) and can be inserted into the drive sleeve and removed therefrom from the condenser side. The vapour throughflow tube (8) can be removed for adaptors (5) or condensers (4) which already have an integrally formed vapour throughflow tube (8). Thus, in the case of the rotary evaporator according to the invention, both the use of conventional glass components without a formed-on vapour throughflow tube as well as the use of glass components having an integrally formed vapour throughflow tube are possible. <IMAGE>

Title: Circuit arrangement for a telephone subscriber station with a control device
Inventor: VOGT WALTER
IPC: H04M1/53
Filed: 1986-12-20
Abstract: The circuit arrangement for a telephone subscriber station with a push-button dialling device for generating dial pulses has a first switching means which is looped into one speech wire and which serves to generate the dial pulses by means of loop interruption, and a second switching means which earths the speech wires on the basis of an earth key actuation. Both switching means are designed as transistors. The loop current is used to supply the electronic components with power. To ensure that the loop current can also flow when the loop is closed, the transistor which interrupts the loop is switched to the conducting state and both switching means are enabled only by a reset signal generated from a voltage control, the reset signal comprising the rising edge of a continuous signal.

Patent DE-3725332-A1 (DE)
Title: Container
Inventor: WAGGERSHAUSER KONRAD DIPL ING
IPC: G01F23/20
Filed: 1987-07-30
Abstract: Conventional containers have essentially tubular supports, in which case the strain gauge devices used for measuring the filling level have to be arranged on at least two opposite sides of each support. This requires a large number of strain gauges and a corresponding outlay in terms of circuitry. In order to make the filling-level measurement simpler and to expose it to fewer sources of error, the new container is provided with supports whose cross-sectional profile has a web extending in the region of the neutral axis of the supports. If the strain gauge devices are arranged on this web, one strain gauge device per measuring location is sufficient since compensation of the support deflection under the container load is no longer necessary. The invention is particularly suitable for hoppers.

Title: Sealing arrangement, in particular for the plunger of a spraying-agent pump serving to discharge liquid spraying agents
Inventor: STICHERT HANS-JUERGEN DIPL ING
IPC: B05B11/00
Filed: 1987-11-28
Abstract: Sealing arrangements of known types, which are described as packing V-cups, by means of axial prestress cause the individual V-cups to interlock positively and to spread outwards. In the case of wear of only one of the V-cups, the prestress of the overall assembly diminishes. The sealing effect is lost. In order to overcome this disadvantage, provision is made for each V-cup to consist of a material which acts at least partially in an elastic manner, and to have room for axial movement on its limbs and, furthermore, for the spring element to be arranged in the open annular space of the V-cup, to be supported with prestress on the limbs and to be pressed against the V-cup in a positive-locking manner at the tip of the V. By this design, each individual V-cup acts as an individual seal in the packing. The sealing arrangement is particularly suitable for the plunger of a spraying-agent pump serving to discharge liquid spraying agents. <IMAGE>
Patent DE-3741326-A1 (DE)
Title: Adjusting device
Inventor: LIXENFELD FOLKMAR
IPC: F01L1/348
Filed: 1987-12-05
Abstract: A typical problem of mechanical engineering lies in the relative rotation of a shaft in relation to another shaft during operation. Existing systems are too complex and expensive. The solution to this problem must be simple in terms of construction and operate reliably.   In particular the drive of camshafts in motor construction is complicated since a very wide variety of vibrations have to be anticipated. By using drive means of continuous design in conjunction with the adjusting device, a cost-effective and operationally reliable possibility of relative adjustment is provided since the underlying principle of length variation is elementary.

Patent DE-3803304-A1 (DE)
Title: Profiled insert
Inventor: SKOV ROMAN MARTIN
IPC: A61F5/01
Filed: 1988-02-04
Abstract: Profiled inserts are known for compression bandages which are intended to support the function of the venous valves in the foot of a patient. Difficulties arise on application of such compression bandages because the profiled inserts have to be fixed. This usually requires the help of another person. The profiled insert comprises a profiled shell having a front edge and a rear edge and an elastic band which connects the front edge to the rear edge of the profiled shell. As a result of this, the profiled insert can be pulled over the foot like a stocking and is then fixed. Subsequent wrapping of the profiled insert with a bandage can then be done by one person alone. The profiled insert is used for compression bandages. <IMAGE>

Title: Boring appliance for pipelines
IPC: F16L41/06
Filed: 1988-06-18
Abstract: The invention is directed towards a boring appliance which, apart from the drilling implement, contains a boring connection to be bored with it and a gate interacting with it in a sealing manner. In order to obtain a low overall height and easier manipulation, it is proposed to arrange the drilling implement and the housing of the gate in such a way that they are fitted into each other on the boring connection, the drilling frame being screwed in place in the interior of the boring connection, while the gate housing acts in the peripheral area of the boring connection. Arranged between the drilling frame and the drilling rod are the two halves of a rotary driver which come into engagement with one another when the drilling rod is raised. The drilling frame can thereby be screwed out of the boring connection again. In the process, the drilling implement moves into a space of the gate housing above a stop member passing through it. The drilling implement can thereby be attached and dismantled with the boring connection sealed.

Title: Shield driving method for a tunnel
IPC: E21D9/06
Filed: 1988-08-12
Abstract: Shield driving method for a tunnel by means of a shield driving machine which has a working chamber under atmospheric pressure, the heading face being supported by means of a pressure medium which is connected via the control gap of the shield to the gap space between shield tail or soil or rock and tunnel lining. The gap space is closed off towards the working chamber between shield tail and tunnel lining by a gap sealing ring. Grouting concrete is injected into the gap space through pipe sockets in the gap sealing ring. For the purpose of closing any possible leakage seam between the gap sealing ring and the shield tail and/or the tunnel lining, work is carried out with a grouting concrete which has fine additives and coarse-grained aggregates such that the coarse grains form a grain filter in front of any leakage seam, the pores of which grain filter are closed by the fine additives. <IMAGE>
