Title: Current flow converter circuitry esp. for personal computer - uses transformer free-wheeling diode and switches to provide several output voltages independently regulated at low loss for PC or TV receiver
Inventor: LIEGL GUENTHER DIPL ING
IPC: H02M3/335
Filed: 1992-07-11
Abstract: A prim. current circuit (PSK) is formed from a series circuit of a prim. winding (PW) of a transformer, a first switch element (SE1) for impulse duration modulation of the voltage to the prim. winding (PW) and a first current measurement device (SME1). A first regulating circuit (RS1) controls the first switch element (SE1) and n sec. current circuits (SSK1) are available, each of which is formed from a sec. winding (SW1) of the transformer. An accumulator choke (DR) is connected serially to the sec. winding, a free wheeling diode (D1) is in parallel with the sec. winding, together with a smoothing capacitor (C) parallel to an output d.c. voltage (Ua) of the sec. current circuit (SSK1). In each sec. current circuit between the sec. winding and the accumulator choke a second switch element (SE2) for impulse duration modulation of the voltage to the accumulator choke (DR) is inserted.

Title: Spacers for use on reinforcing rods embedded in concrete - are thermoplastic mouldings of e.g. polyamide with centre tube to slide along rod into position and are then bonded to rod when heated
Inventor: DREIZLER SELMA
IPC: E04C5/20
Filed: 1992-07-27
Abstract: Spacers for reinforcing rods used in the production of concrete are attached in sets to the rods and embedded with them in the concrete components. Each spacer is moved along the rod concerned and has parts which can be softened and which, when heated, bond (at least on some areas) to the reinforcing rod. A method of attaching the spacers is also claimed. Pref., the figure shows the shape of the plate-like spacer in plan view, with its symmetrically disposed four arms (40). This shape also saves material when compared with a circular spacer. It is moulded in one piece, in e.g. polyethylene, polypropylene, or polyamide. It has a centre tube (35) to fit over the ribs (30) along the surface of the reinforcing rod and over the spiral ribbing (31) similarly. These ribs are irregularly disposed and leave intermediate spaces (32). When heated, the adjacent parts of the tube (35) can flow into these spaces. The tube (35) thus requires to have sufficient wall thickness to allow for this. The spacer is heated to e.g. 180-200 deg. C and pressed on to the rod at 200-1,000N. ADVANTAGE - The spacers can be bonded to the reinforcing rods simply, cheaply and reliably. They withstand the stresses which arise when the concrete article is being made. The permit the use of ribbed steel rods.

Title: Establishing telephone party line subscriber connection - adjusting reception amplification at each end of connection to provide damping compensation
Inventor: LISNER PAUL RUDOLF DIPL ING
IPC: H04Q5/02
Filed: 1992-08-26
Abstract: The connection system allows a speech connection to be provided between two telephone subscribers coupled to the same party line. The calling subscriber (BT1) provides a line request signal having a given reference level received by the called subscriber (BT2) to initiate the required damping compensation for the connection duration via the reception amplification. The called subscriber transmits a quitting signal having a second reference level used by the calling subscriber to initiate damping compensation by adjustment of the reception amplification. Pref. the reception amplification for both subscribers is reset automatically to its normal value when the connection between them is released. ADVANTAGE - Automatic stable level regulation for duration of call connection.
Patent DE-4238131-A1 (DE)
Title: Layout for applying plastic coating on to surface of moulding - injects coating into mould already containing article, and through gate which is narrower than outer groove holding rib on moulding
Inventor: HERRMANN MICHAEL
IPC: B29C45/14
Filed: 1992-11-12
Abstract: A layout sprays a plastic coating on to a plastic article, and particularly on to a casing for a vehicle lamp. The coating is applied from the opposite side concerned and through an opening in the article. In the process the article is placed in an injection mould and the layout concerned is an injection mould which opens and closes in a main split plane. The injection opening is wider than the narrowest cross-section of the gate to the mould. The gate side of the moulding wall has a rib round the rim of the opening. The gate is surrounded by a groove into which the rib fits, and the gate leads to the space formed by the rib. As an example the figure shows the layout for coating a car rear lamp casing. The coating has one surface (2) penetrated by the opening (9) for injection; the mould (11) thus has the injection gate (12). Here the wall (10) of the moulding has a rib (14) round the gate whose inlet side (13) is surrounded by the groove (15). ADVANTAGE - The layout produces high grade coatings which are free from the usual faults (e.g. varying thickness of coating).

Title: Detecting repeating burst type in given time frame
Inventor: EICHINER GERHARD DIPL PHYS
IPC: H03M13/39
Filed: 1994-01-05
Abstract: The method recognises a repeating burst type in a given time frame in the data stream of a time multiplexed system, using a detector circuit (1). The received data signal is fed to the detector circuit (1). The output of the detector (1) is connected to the memory (3) of a first counter (2) and a memory (5) of a second counter (4) which divides the interval (T) of the first counter (2) into K sub-sections. The memories (3,5) store the current counts of both counters (2,4) when the detector (1) announces the desired burst type. A difference member (7) is connected to the second counter (4). From the difference Bi-Bk, the number of burst announcements in several adjacent positions is determined, and, from this, a third counter (14) is increased to a maximum via comparator (11). By exceeding a threshold dependent on the counter values, the probable position of the sought burst type is ascertained.
