Patent DE-3536838-A1 (DE)
Title: Arrangements for spring-mountable, conical rings
Inventor: EICKMANN KARL
IPC: F04B43/08
Filed: 1985-10-16
Abstract: From the calculations of Almen and Lascio, it has been known for 50 years precisely which stresses occur at which points in disc springs. These calculations do not however indicate the point of maximum stress of the disc spring. According to the findings of the invention, the stress at the support lines is much greater than within the spring. As a result, high friction occurs in the radial direction with conical rings resting on the plane. In order to overcome this friction which can consume forces up to ten times greater than the force required to compress the disc spring, ring components which yield in the radial direction are assigned to the conical ring or to the disc spring. Pairs of disc springs are also held together by means of rings which contain such radially yielding annular elements. By means of the arrangement of these radially yielding annular components or annular elements, high frictional losses are avoided. In the case of conical rings used as pumping elements in high-pressure pumps, the originally required force is reduced to almost a tenth. <IMAGE>

Title: Circuit arrangement for clock recovery
Inventor: SCHEMMEL HANS-ROBERT DIPL ING
IPC: G11B20/14
Filed: 1985-11-07
Abstract: The described circuit arrangement for clock recovery has a pulse former stage on the input side, the output of which is connected to one input of a gate, while the other input of the gate is activated by an evaluation circuit of a counter. The counter is timed by a clock source whose frequency is higher than the frequency of the clock which is to be recovered, the counter controlling the evaluation circuit and being reset by the output signal of the gate. In order to avoid all possible counter reset errors and to produce a clock which is virtually jitter-free, it is provided to design the evaluation circuit as a decoding matrix which converts the counter reading into a binary signal with which the gate is opened for a predefined sequence of counter readings, to use as a clock source the voltage-controlled oscillator of a phase-locked loop whose input for the control parameter is connected to the output of the gate and to tap the recovered clock from the output of a frequency divider whose input is connected to the output of the voltage-controlled oscillator.

Title: Gear machine (pump or motor)
Inventor: RUSTIGE HAYNO DIPL ING
IPC: F04C15/00
Filed: 1986-01-25
Abstract: The gear machine has two gears (14, 15) which mesh with one another in external engagement and the shaft journals of which are mounted in bearing bores formed in the housing covers (11, 12). Situated on both sides of the gear side surfaces are spaces (31, 32), in which a seal (29) is arranged, which consists of sealing plate, support ring (40) and insert (42) for pressure field limitation. The sealing plate is pressed against the gear side surfaces and in particular by high pressure being introduced in a cavity (41) formed by the sealing plate (35) and the support ring (40) and receiving the insert. As a result, the sealing plate (35) is pressed against the gear side surface. The support ring (40) simultaneously separates a high-pressure field (D1) from a low-pressure field (D2). This seal does not - as otherwise usual - need to be arranged in complicated grooves but is situated in the space (31 or 32). As a result, the gear machine is simplified considerably. <IMAGE>

As a result of the special design of the rails and carriages, it is possible for the elements to travel even over crossings, over any angles and over branches in a simple way. The system is especially suitable for those partition walls which are to be assembled quickly and frequently, if appropriate at different locations, and thereafter are to be moved into a stowage region again.
Patent DE-3615522-A1 (DE)
Title: Telephone set
Inventor: HECHT GERHARD DIPL ING
IPC: H04M1/715
Filed: 1986-05-07
Abstract: If a plurality of telephone sets can be connected in series or in parallel with a subscriber connection line and if at least one of these telephone sets has a call charge meter which is controlled on the basis of AC signals transmitted via the subscriber connection line outside the voice band, there is a risk in the case of the other telephone sets which have no call charge meter of the ear protection in the listening circuit being destroyed by charge pulses which are excluded from the talking and listening circuit by a blocking filter in the case of the first-mentioned telephone sets, particularly if the subscriber connection line is short. To prevent this, a blocking filter in the form of a series resonant circuit is plugged as a module into the secondary earpiece.
Patent DE-3619071-A1 (DE)
IPC: B23Q11/10
Filed: 1986-06-06
Abstract: A machine tool has a spindle head pivotable through 180 degrees and having a spindle rotatably mounted in its housing. As a result of the pivoting movement, the spindle head can be shifted from a vertical to a horizontal working position. The spindle head has a toolholder and an axially displaceable tension rod. Through the tension rod runs a coolant bore extending into the working zone of the clamped tool. The coolant bore is connected to a line in a transfer piston displaceable in the spindle-head housing. The coolant bore and the transfer piston line are constantly in communication so that coolant flows uninterruptedly during displacement of the transfer piston. The line communicates with a coolant supply system. The coolant can be conveyed into the working zone of the tool in any position of the tool spindle and without any appreciable increase in size of the spindle head.

Title: Cross-bar quadrature mixer
Inventor: MENZEL WOLFGANG DR
IPC: H03D13/00
Filed: 1986-09-20
Abstract: This mixer is particularly intended for the millimetre waveband. The waveguides for the RF signal (RF) and the local oscillator signal (LO) extend immediately next to one another in parallel. A substrate with a coplanar line is inserted across the line direction into the waveguide for the RF signal (RF). The substrate is continued through an opening in the common wall of the two waveguides. To connect the local oscillator signal (LO), the inner conductor of the coplanar line protrudes into the LO waveguide. The waveguide for the RF signal (RF) is terminated by a displaceable short-circuit behind the substrate. On the coplanar line, two diodes (D1, D2), which are perpendicularly irradiated by the RF signal, are mounted at a distance of  lambda /4 from one another with common earth. <IMAGE>

Patent DE-3708396-A1 (DE)
Title: Spray can with atmospheric air as pressure medium or propellant
Inventor: WEIGL ROBERT DIPL ING
IPC: B65D83/14
Filed: 1987-03-14
Abstract: Instead of using inert gases or rare gases as propellant gases for commercially available spray cans, compressed air is used in the present invention. Since atmospheric air is chemically non-inert, the propellant (propellant gas) has to be separated from the spraying medium. This takes place by means of a thin membrane in the form of a balloon. Many spraying media, which must not be mixed with the propellant gas consisting of compressed air for the reasons given, are filled directly with inert gases without separation. These then also emerge into the environment during the spraying operation and, since they are lighter than air, rise into the atmosphere. The separation insert in the form of a balloon obviates the need for using propellant gases. The costs for the balloon and any necessary modification of the spraying valve are approximately the same as the price of the propellant gas.
