Title: Device for pressing windings of a transformer
Inventor: PFLUGBEIL DIETMAR DIPL ING
IPC: H01F27/30
Filed: 1983-02-28
Abstract: Such devices are generally constructed using pressure segments (8) which extend in the radial direction over all the windings (2, 3) allocated to a core limb (1) and press said windings in a uniform manner, the pressure segments (8) being themselves supported via blocks (15) on yoke-pressing bars (14). According to the invention, the distance between the pressure segments (8) in the circumferential direction is approximately equal to the width of the pressure segments (8) on the core side, and pressure bridges (9), which are supported in a jointed manner on the pressure segments (8), are located between mutually opposite, approximately parallel sides of said pressure segments (8), the boundary surfaces of the pressure segments (8) and of the pressure bridges (9) facing the windings (2, 3) lying in the same plane. The use of the arrangement according to the invention and the design of the pressure segments (8) and pressure bridges (9) permits very good spatial utilisation in the iron-core window, using simple, longitudinally-laminated synthetic-resin compressed wood. The clamping force which is to be applied onto the windings (2) and (3) via the supporting elements (10) and (11) is in this case distributed uniformly over their complete circumference. <IMAGE>

Patent DE-3340698-A1 (DE)
Title: Shut-off valve arrangement
Inventor: MAEHLER ANDREAS
IPC: F16D48/02
Filed: 1983-11-10
Abstract: The subject-matter of the application is a valve arrangement for shutting off hydraulically actuated devices, such as couplings, when the hydraulic pressure medium is at a negative pressure. The arrangement comprises a housing and a piston which is axially displaceable in the housing and is acted upon on the one side by the pressure medium and on the rear side by at least one coaxially acting compression spring and via which a return passage for the pressure medium is opened as a result of displacement by the spring during negative pressure. Such a valve arrangement is now to be arranged in a bypass for the relevant working cylinder in order to connect its pressure connection to the return to the tank of the hydraulic system during negative pressure, leakages being avoided at the operating pressure applied to the valve arrangement. To this end, a seat valve is arranged with a valve body in a surrounding pressure-medium space coaxially to the piston in the housing, and the return passage leads into this pressure-medium space, the valve body, in its closed position, closing off the return passage from the pressure-medium space, and at least one mechanical transmission member being arranged between the valve body and the piston, which transmission member, with the displacement of the piston during negative pressure, drives the valve body from its closed position into the open position.

Abstract: A process for mounting a piece of glass in a bay, particularly the windshield of a motor vehicle, is disclosed which comprises forming a first bead of hardenable adhesive material on the edge of the glass to be inserted in the bay, and thereafter superpositioning said bead on a second bead of adhesive material compatible with said first bead and pressing the glass piece into the bay, while the second bead hardens. The second bead may be formed either on the first bead of adhesive material, or in the bay itself, immediately prior to insertion of the glass piece. Preferrably, the first formed bead has a section exhibiting a tongue or protrusion extending away from the periphery of the glass towards the bay, which serves to contain the lateral expansion of the second bead of adhesive material upon pressing, and hides the second bead of material from view upon insertion.
Patent DE-3422543-A1 (DE)
Title: Internal combustion engine
Inventor: LEGAT REINHARD
IPC: F02B1/04
Filed: 1984-06-18
Abstract: In an engine of the type proposed, a large proportion of the charge mass flows out through the main flow duct in advance of the bottom dead centre owing to the ultimate high expansion pressure, whilst a residual partial mass flow is exhausted through another duct. Since a smaller mass flow per unit time prevails in the duct for the residual partial mass flow, this results in smaller exhaust losses, since they have to be exhausted against a lower pressure level, as a result of lower back pressure at the throttle points. Since smaller peak pressures act from the cylinder chamber, the throttling in the exhaust line for residual partial mass flow does not need to be so pronounced, which in turn has a positive effect on the exhaust work to be expended. A turbine is driven by the main mass flow, which turbine influences the residual partial mass flow in such a way that the discharge of burnt gases from the combustion chamber, which open into the port for the residual partial mass flow, is supported.

Title: Apparatus for drawing off and metering a plastic mass, especially of sausage meat
Inventor: KRAUS FERDINAND
IPC: B65B3/30
Filed: 1984-07-06
Abstract: In an apparatus of this type, the plastic mass which has been placed in a filling cylinder is discharged from the filling cylinder by means of a hydraulically drivable filling piston through a blocking element which can be controlled between an open and a closed position. To determine the metered quantity, the quantity of hydraulic pressure medium required to drive the filling piston is measured in a throughflow volumeter 30, which generates a corresponding number of electrical pulses. If the number of pulses matches a predetermined desired value, the supply of pressure medium is interrupted by an electronic control device (49, 50) and the blocking element is controlled into its closed position. A pulse discriminator (32) checks for the presence or absence of pulses from the throughflow volumeter 30, thereby displaying data indicating the end of the previous metered quantity so that the following metered quantity can be discharged. Furthermore, the data of the pulse discriminator (32) is used to correct errors in the sizes of individual metered quantities (Figure 3). <IMAGE>
