Patent DE-3829692-A1 (DE)
Title: Flow-regulating valve, in particular for sanitary fittings
Inventor: VIDOR GYOEZOE
IPC: F16K47/02
Filed: 1988-09-01
Abstract: The invention relates to a flow-regulating valve with inlet and outlet openings, between which a fixed inlet disc with a through opening and a control disc with a control opening rotatably mounted on the inlet disc are arranged in the valve housing. Arranged on the control disc is a sintered disc which is synchronous in rotation with the control disc and engages by means of a projection in the control opening, more specifically in the region of the control opening in which the overlap with the through opening begins when the valve is opened. This prevents a troublesome singing noise at the beginning of valve opening. <IMAGE>

Patent DE-3837449-A1 (DE)
Title: Device for kinematically cutting, bending and milling oval or circular shapes
Inventor: KOCH JOSEF
IPC: B26F1/38
Filed: 1988-11-04
Abstract: The device for kinematically cutting, bending or milling oval or circular shapes makes it possible to produce the desired shape as soon as an order has been placed. It is based on a synthesis of rotary and linear movements. Transmission of the rotary lever movement of the relative scale between two spindles which are mounted in carriages to their linear guides leads to kinematic analysis. The oval or circular shape can be passed on by the spindles by means of a lever, the set end point of the lever corresponding to the radius. Different materials can be processed in this manner. Angular cuts can be made for master keys. The device is continuously adjustable, so that the customer is free to determine the size and shape by specifying the dimensions in an accurate manner.

Title: Method and apparatus for connecting the end of a tubular workpiece to a shaped part of the same geometric constitution
Inventor: KALBERG FRIEDEL PAUL
IPC: B23K37/053
Filed: 1988-11-05
Abstract: Long cylindrical pipes are to be connected to shaped parts of the same geometric constitution, such as flanges or bends, by butt-joint external circumferential welding by means of a welding head in a forming or inert-gas atmosphere while jointly clamped by means of a clamping head (5) and during a relative movement between welding head and workpiece. To permit clamping of the parts solely from inside and to permit universal use even on construction sites for workpiece lengths and dimensions usual in practice, in particular for high-grade steel pipes, the welding head (32) is to be set and fixed in a freely predeterminable position relative to the circumference of the joint, the parts to be joined are to be directly driven via their restraint by means of the clamping head with overhung mounting and support of the clamping-head holder (53) via a hollow bearer (6) connected to a drive (2), and the requisite fluids are to be fed through the clamping head to the joint. <IMAGE>

Patent DE-3842248-A1 (DE)
Inventor: KOSTUN JOHN D
IPC: F02M35/14
Filed: 1988-12-15
Abstract: A compact combination engine air cleaner/noise deadener for installation in the engine compartment of a motor vehicle type engine includes a two piece plastic elongated housing that is compact and has an ambient air inlet at one end radially spaced from an air outlet to the engine located on the axis of the housing, the inlet containing a first noise attenuating venturi, the housing having an air filter at the other end connected to the venturi and discharging air into a second convergent-divergent flow control noise attenuating venturi with which is integrated a mass air flow sensor, the venturis being surrounded by a dead air space type resonating chamber that has an inlet concentric with the air outlet so that engine feedback noises and sound waves are trapped in the chamber and dissipated, and any sound waves passing serially into the venturis bounce off the walls of the venturi diffusers to also be dissipated, thus minimizing the transmission of engine feedback noises past the air cleaner.
Patent DE-3902270-A1 (DE)
Inventor: RICHTER GUENTER DIPL ING
IPC: B29C48/475
Filed: 1989-01-26
Abstract: The invention relates to a method for discontinuously manufacturing multilayered coextruded tubular preforms made of thermoplastics for forming large-volume, multilayered hollow articles in a split blow mould, in which at least two different, annular material melts are brought together centrally within the annular ram one after the other and in the direction of extrusion to form a multilayered material melt and in which this multilayered material melt flows outwardly in the shape of a funnel into an annular accumulating space and is subsequently discharged by an axially movable annular ram, which acts as a coextrusion head and is forced upwards by the multilayered material melt, via an annular die gap, so that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels before their entry into the coextrusion head. 
<??>In order to improve the known method in such a way that cross-sectional changes no longer occur in the transitional area between the respective extruder and the annular ram, so that weak points are avoided or are reduced to such an extent that they no longer have an adverse affect on the finished hollow article, it is proposed that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels of the annular ram before their entry into the coextrusion head.

Patent DE-3902616-A1 (DE)
Title: Gas-cylinder valve with a pipe- or hose-break valve
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F17C5/02
Filed: 1989-01-30
Abstract: Pipe- and hose-break valves close the gas path in the direction of flow out of the gas cylinder as soon as a predetermined permissible flow rate is exceeded, for example when a pipe break occurs. However, these pipe-break valves are not suitable for the filling of a liquified gas cylinder. Rapid filling of a liquified gas cylinder is made possible with a valve cone which under elevated gas pressure such as that which occurs during the filling of a gas cylinder opens up an enlarged gas flow path in the reverse flow direction and can be either installed in a cylinder valve, mounted at the outlet of the cylinder valve or mounted at the inlet of an immersion tube.
