Patent DE-3907103-A1 (DE)
Inventor: MUSSGNUG HANS
IPC: F16K5/06
Filed: 1989-03-04
Abstract: In a fitting such as a valve a spindle (13) which is accommodated in a mounting opening (11) extending through a wall of a casing (12) is sealed by means of a gland assembly (10) including a sealing sleeve (20) which closely surrounds the spindle (13), and a spring ring (22) of expanded pure graphite which concentrically surrounds the sealing sleeve (20). An axial biasing force applied to the spring ring causes the spring ring (22) to be radially braced between the casing (12) and the sealing sleeve (20), whereby the sealing sleeve (20) is pressed radially against the spindle to produce static and dynamic sealing. The spring ring (22) may bear directly against the casing (12) or it may be accommodated in a sealing sleeve member of U-shaped cross-section. <IMAGE>

Title: Method for symmetrising the voltage sharing in power converters having multi-point connection
Inventor: SKARPETOWSKI GRZEGORZ DR
IPC: H02M7/48
Filed: 1989-03-11
Abstract: For traction drives with high power, converters having impressed intermediate-circuit voltage and three-point power converters (28-39) are used for supply. When auxiliaries are supplied from partial-voltage sources (C1, C2), or when, in the event of switching to partial voltages, the corresponding capacitor voltage dividers (C1, C2) are unequally loaded, asymmetric voltage sharing (U1, U2) on these capacitor voltage dividers can result. In order, with low circuit complexity as regards hardware, to achieve symmetrisation of the capacitor partial voltages (U1, U2), the two capacitor partial voltages are compared with each other. If one capacitor partial voltage (U1) differs from the other (U2) by more than a predeterminable limit value, then next time a partial-voltage switching state of a three-point power converter (28-39) is demanded from a control device, the capacitor voltage divider (C1) chosen will be the one which has the higher partial voltage in the case of loading, whereas, in the case of supplying, the capacitor voltage divider (C2) chosen will be the one which has the smaller partial voltage. <IMAGE>

Title: Continuous casting plant in which the mould has travelling walls
Inventor: BOLLIG GEORG DR
IPC: B22D11/06
Filed: 1989-04-07
Abstract: A description is given of a continuous casting plant with a novel mould that has walls which travel in the vertical direction. The walls of the mould are formed by link chains, each consisting of metal blocks (1 to 4) which are guided so as to revolve and, in the direction of travel, are arranged one behind the other in closed formation, at least in the region of the mould. The mould walls consist of four link chains forming, in a cross-sectional view of the mould, a rectangle with variable side lengths. In the region of the mould, each link chain preferably rests against the link chains perpendicular to it. On one side, the upper, mould-wall-forming face of its metal blocks (e.g. 1) rests against a side face of the metal blocks (e.g. 2) of one link chain perpendicular to it and, on the other side, the side face of its metal blocks (e.g. 1) rests against the upper, mould-wall-forming face of the metal blocks (e.g. 4) of the other link chain perpendicular to it. In the region of the mould, each link chain is furthermore slanted obliquely to the longitudinal axis of the mould and, at the same time, transversely to its direction of running. This allows it to follow the slant of the adjoining link chain, against the mould-wall-forming face of which it rests with one of its side faces. <IMAGE>

Patent DE-4004119-A1 (DE)
Inventor: TEWS MANFRED DIPL ING
IPC: A61M31/00
Filed: 1990-02-10
Abstract: The invention relates to a process and a device for determining the moisture content of the material of a test object using microwaves. The properties of a resonator such as resonance frequency, resonance half-width value and amplitude of the resonance can be measured using a digitally tunable quarz-stable PLL-controlled microwave generator. By special processing of the variations in the results due to detuning of the resonator when it is being filled with a product, the moisture content of the material in the product can be measured exactly, independently of the density of the material and largely independently of the type of material and of changes in additives. The same measurement equipment without any rearrangement of the hardware can be used both in the ppm range and up to moisture contents greater than 80 %. In addition, there are no special requirements concerning the shape of the sample.

Title: Grip to draw warp ends through shed -  has a swing and rotating movement to maintain yarn tension through shed in a seaming machine
Inventor: PREUNER CHRISTIAN
IPC: D03D3/04
Filed: 1990-09-21
Abstract: The gripper in a seaming machine, to take the warp ends from a transfer grip, for drawing into an alternately opened shed, has a rotary electrical or pneumatic drive so that when the grip has taken the yarn from the transfer grip, it moves over the whole seam width to apply tension to the yarn, parallel to the woven selvage. Then, lay it parallel to the selvage, it follows a circular movement to give a full insertion in the shed while the yarn is held under tension. The movement of the grip is controlled by two step motors. One step motor is a linear motor with a linear unit to apply a reciprocating movement on the direction of the fabric selvage to which the other step motor is firmly mounted, with a drive shaft to swing the gripper arm of the grip on a circular path. ADVANTAGE - The movements of the grip ensure that the warp yarn is under tension at an angle of 30 deg. to the selvage, even with narrow seams, and its tension is maintained while it is completely laid in place without yarn distortion.

Patent DE-4035861-A1 (DE)
Inventor: TERKOWSKI JUERGEN
IPC: H04M1/65
Filed: 1990-11-10
Abstract: To an increasing extent in subscriber equipment, device combinations, usually comprising a telephone set, answering machine, facsimile machine, cordless telephone etc., are connected to the main subscriber line. As studies have shown, it should also be possible in future device combinations to convey a message from the temporarily absent subscriber to a calling subscriber. The circuit costs and other expenditure required for this purpose are essentially determined by the read/write memory used. To ensure that the user, while retaining his customary mode of operation, for example his manner and speed of speaking, can input messages for a calling subscriber in a serial read/write memory, the size of the memory areas can be varied according to the length of the messages to be stored within fixed limits predefined by the control device in such a way that the occupied physical memory areas are connected to one another in seamless fashion. Furthermore, a forward-backward counter is connected to the read/write memory and to the control device, which counts backwards during the writing operation and forwards during the reading operation, while the respective counter reading is shown on a segment or matrix display. <IMAGE>
