Patent DE-3526140-A1 (DE)
Title: Roller blind winding device
Inventor: NAKAMURA DAIJIRO
IPC: E06B9/74
Filed: 1985-07-22
Abstract: The present invention relates to a roller blind winding device and is characterised in that the output of a motor, the direction of rotation of which can be reversed, of the external rotor type, which is arranged in a roller blind winding shaft, is transmitted to the winding shaft with reduced speed. A braking force is applied by a braking mechanism to the moment of inertia of the motor synchronously with the motor being set out of operation. The number of rotations of the winding shaft is counted by a counting mechanism and the motor is set out of operation at a predetermined number of rotations. The output of a hand drive shaft, which can be turned manually in both directions, is transmitted to the winding shaft via a self-blocking mechanism after reduction of the rotation speed.
Patent DE-3531847-A1 (DE)
Title: Circlip pliers
Inventor: MIHALCEA RADU
IPC: B25B5/16
Filed: 1985-09-06
Abstract: The tool projections of circlip pliers engaging in the assembly holes of a circlip have recesses which point in the tensioning direction and accommodate marginal sections of the assembly holes. The bore surfaces of the assembly holes consequently bear, for example, in a point-like manner on the tool projections during the tensioning operation and in a linear manner on the tool projections in the tensioned state. Unintentional sliding of the circlips on the tool projections is thereby avoided in all tensioning phases.

Title: Signal waveshape equalizing circuit for an information recording/reproducing device
Inventor: DOI MASANORI
IPC: G11B20/10
Filed: 1985-09-12
Abstract: A cosine signal waveshape equalizing circuit, in which signals read from a disk of an information recording/reproducing device, for instance an optical disk device, are fed to a delay circuit and a damping circuit, the outputs of which are connected to the two inputs of a differential amplifier. A switching circuit can alter a switching constant of the delay circuit and/or of the damping circuit, the switching circuit being controlled by a control means which generates a control signal corresponding to a track region on the basis of that track address which is calculated from the position of rest in which the information recording/reproducing device starts, and according to the following extent of movement and the direction of the pick-up. The signal waveshape equalization is consequently carried out optimally, irrespective of the reproducing position of the pick-up.

Title: Stove for a closed hot-air heating system
Inventor: ZEIDLER HANS
IPC: F24B7/00
Filed: 1986-01-15
Abstract: The invention relates to a stove for a closed hot-air heating system having a stove housing (2) in which insulated and non-insulated hot-air ducts (7, 8, 9) and also a heating insert (14) with a heat-storage plate (10) are arranged. The hot air is conducted through the hot-air ducts in a circuit and delivers its heat to the non-insulated hot-air ducts on the heating surfaces, for example walls (5), floor (6) or tiles of the stove. In the insulated heating ducts, the air is reheated via the heating insert. The heat-storage plate (10) surrounds the heating insert (14) annularly and thus forms such a hot-air duct. The heating insert (14) provides immediate heating of the air, whereas the heat-storage plate heats over a longer period of time. <IMAGE>

Title: Circuit arrangement for an exchange circuit in a telephone branch exchange
Inventor: HELSMOORTEL LUC
IPC: H04M7/00
Filed: 1986-07-23
Abstract: To match the AC-coupled exchange line to the terminal of a switching network with single-conductor switching, an arrangement make up of operational amplifiers is used, in which an operational amplifier (OP2), the output end of which is connected to the exchange line section at the branch exchange end via a transistor (TR), is in each case only controlled by voice signals coming from the switching network. The signal is picked up across a voltage divider, which is also formed by a balancing resistor, and conducted via the line transformer (LÜ) which is used for DC isolation, to the exchange line (AL). A simple arrangement (TR, R8, R9) ensures that audio frequency signals from the switching network do not reach the receiving branch. This is only possible for signals which are received via the exchange line (AL). For such signals, a reaction to the exchange line is impossible due to the effect of the operational amplifier (OP3) which is located in the actual transmitting path. <IMAGE>

Title: Integrated services broadband time division multiplex communications system
Inventor: ALI AMAR DR
IPC: H04J3/16
Filed: 1986-12-13
Abstract: In a multiplexer/demultiplexer for a digital broadband communications system with a plurality of integrated service, in particular for transmission via the subscriber connection line, a pulse frame is provided according to the invention, which comprises 78 columns and 30 rows, forming 2340 time segments each with 8 bits, and which has an 8-kHz frame repetition rate. On the basis of this pulse frame, multiplexers/demultiplexers can be designed which can be set up without substantial storage cost for the different bit repetition rates for the H4-channel, the H1-channel and H2-channels which are currently the subject of standardisation discussion. Even multiplexers/demultiplexers which can process different bit repetition rates in different operating modes can easily be implemented. The transmission bit repetition rate is 149760 kbit/s. Particularly favourable use is made of the pulse frame when the H4-signal has a bit repetition rate of 138240 kbit/s and the H1-signals have a bit repetition rate of 1920 kbit/s. <IMAGE>
Patent DE-3700795-A1 (DE)
Title: Clamping device for the extra-oral treatment of natural teeth
IPC: A61C3/14
Filed: 1987-01-14
Abstract: A clamping device (1) has a forceps-like jaw formed only by two opposite clamping members (2, 3). One clamping member (2), which executes the clamping movement, can be variably loaded by a tensioning spring (6) in such a way that it rests against the clamped tooth at a desired prestress but can nevertheless be transferred directly into an opening position counter to the prestress, and without any change of the other settings of the clamping device (1), for relocation of the tooth. The clamping surfaces (27, 28) are a groove at right angles relative to the direction of the clamping movement (arrow 14), on the one hand, and a bowl-shaped depression, on the other hand, so that the tooth can rest at points and hence extremely securely on two contact sites in the groove and on three contact sites in the bowl-shaped depression. The tooth can spontaneously align itself into its most favourable position relative to the clamping surfaces. <IMAGE>
