Title: Circuit arrangement for small PABX systems with a device common to the subscriber stations which performs switching operations with the aid of a control processor unit
Inventor: BLOSSFELDT DIETER
IPC: H04M9/00
Filed: 1981-08-07
Abstract: The invention relates to a circuit arrangement for small PABX systems with a device common to the subscriber stations which performs switching operations with the aid of a control processor unit. The speech wires (a, b) of a connection line which links the respective subscriber station (T1) to the central device (ZE) are connected to the internal (In1 to In2) or external (E1 to E4) paths by a coupling arrangement (KE) which is controlled by the control processor unit (ST). The control processor unit has access to memory arrangements (Sp) in which the respective operating conditions of the telephone stations and also the existing connections are stored. Through the corresponding setting of the coupling arrangement (KE), the speech wires (a, b) can also be connected individually for each subscriber station (T1) via a feed resistor (R) to a DC voltage source (Q) which cannot be incorporated in the connection path. This connection is carried out both directly by the actuation of a switching means (GU) which is to be performed prior to a connection set-up on the subscriber station (T1) and for the subscriber station involved in an existing connection during the period in which a ringing signal (1r3, 2r3) is transmitted for the required subscriber station in order to set up an enquiry connection (e.g. via the sub-section Ei1). <IMAGE>

Title: Apparatus for producing connection pieces made of wood or the like and connection pieces produced with the apparatus
Inventor: WIESER HERMANN
IPC: B27M1/02
Filed: 1981-10-10
Abstract: The apparatus for producing connection pieces made of wood consists of two rollers which roll on one another, have on their curved surface successively arranged negatives of the connection pieces to be produced and are driven in opposite directions. A piece of wood from which the connection pieces are to be produced is inserted between the two rollers, the connection pieces being punched out through the negatives recessed in the curved surfaces of the rollers on passing through the latter. The negatives can have elevations and depressions, through which grooves and webs are created on the surfaces of the connection pieces. The webs and the grooves on both sides of the connection pieces can be arranged offset relative to one another, so that a cross-sectional profile of the pieces with an approximately constant material thickness results.

Title: Body-side support of a shock absorber or spring strut of a wheel suspension for vehicles, especially motor vehicles
Inventor: WALLENTOWITZ HENNING DR
IPC: B60G13/00
Filed: 1981-11-07
Abstract: In the case of a shock absorber or spring strut of a wheel suspension for vehicles, especially motor vehicles, arranged at a divergent angle, its piston rod is elastically supported at a variable angle by its upper end on an elastic support bearing fixed to the vehicle body. At the same time the support bearing, with regard to the range of movement about its design position, is so constructed that a virtually infinite centre of rotation results for the upper point of articulation. This is achieved in that in the case of small vertical compression and rebound movements of the wheel having a low energy content, in which the main damper of shock absorber or spring struts does not even respond and these movements are therefore fully transmitted to the support bearing, such a wheel suspension in its kinematic behaviour nevertheless resembles that of a double wishbone axle on which any variation in the tracking and camber of the wheel turns out to be considerably less than on conventional shock absorber or spring strut axles. The bearing according to the invention thereby permits a significant reduction of the wheelfight on such axles.

Title: Apparatus for producing welded lattice girders
Inventor: KELLER KLAUS DIPL ING
IPC: B21F27/20
Filed: 1982-02-10
Abstract: The invention relates to an apparatus for producing welded lattice girders, with a main feed which can be moved in a reciprocating manner in a timed sequence and transports the lattice-girder line step by step, a cutting-to-length device and an auxiliary feed for depositing the cut-to-length lattice girders at a collecting station. In a known apparatus of this type, the auxiliary feed is provided as a separate construction unit behind the actual welding apparatus and in addition requires a separate control system. Matching the main feed of the welding apparatus to this auxiliary feed is difficult and time-consuming. The object is therefore to simplify an apparatus of the type mentioned at the beginning with regard to the discharge of the finished lattice girders. This object is achieved in that the auxiliary feed is in drive connection with the main feed for a synchronous movement, and in that the auxiliary feed has a separating device with which a respectively cut-to-length lattice girder can be spatially separated from the following lattice-girder line. In this design, the main feed is at the same time also responsible for depositing the finished lattice girders, the separating device always ensuring that the cut-to-length lattice girder is separated from the following line and cannot hang in it. <IMAGE>

Patent DE-3218920-A1 (DE)
Title: Arrangement for ultrasonic welding
Inventor: SCHMIEG RAINER
IPC: B29C65/00
Filed: 1982-05-19
Abstract: In an arrangement for ultrasonic roller welding, the rotationally symmetrical ultrasonic horn (Sonotrode) is widened out in a trumpet-shaped manner. The ultrasonic oscillation is by this means transmitted to the work surface such that the latter oscillates perpendicular to the workpiece. By this means, the high mechanical loading of the workpiece and tool, such as occurs in the transverse rubbing of known roller-welding arrangements, is eliminated. By contactless measurement of the sound amplitude at the work surface, the quality of the welded bond can be checked by means of a control loop and be maintained. It is particularly advantageous to arrange two ultrasonic horns, which are excited in phase with one another, at the welding point on both sides of the material to be welded. By this means, the amplitude for the individual ultrasonic horns can be kept much smaller.

Title: Rotary piston engine with oval rotors
Inventor: EVERT ALFRED PROF DIPL KFM
IPC: F02B75/02
Filed: 1982-11-09
Abstract: A rotary piston engine can be constructed in such a way that in each case four oval rotors rotating uniformly and synchronously about their respective centre define a working space between two plane surfaces at a constant spacing. The working space is kept sealed at all times by counter-engagement if the shape is similar to that of an ellipse, that is represents an ellipse widened in the direction of the minor axis. The minimum volume is enclosed when the narrow sides of the rotors face one another and the maximum volume is enclosed after a rotation through 90 DEG . Any desired degree of compression can be achieved. If nine such rotors are combined, it is possible to construct a four-stroke four-cylinder engine in a very small space. The working spaces are cube-like, i.e. have an optimum volume to surface area relationship. At the time, the gas pressure acts on a maximum proportion of the surface, where it is converted with a predominantly tangential vector and in a direct manner into rotary motion. The walls yield in four directions to the flame front, with a corresponding thermal efficiency. The working throughput is optimum due to large-area, disc-controlled intake/exhaust ports with continuous gas flow and hence an additional scavenging effect. The engine can be constructed as a planetary piston engine with a fixed central body and rotors revolving around the latter on a circular path or as a rotating piston engine without fixed working-space walls and with rotors rotating exclusively in a directly circular manner,...
