Title: Power transistor switching circuit - uses logic circuit to delay switching pulses until required voltage drop across power transistor
Inventor: POPP WERNER
IPC: H03K17/60
Filed: 1980-11-28
Abstract: The circuit controls the voltage across the collector/ emitter path of the power transistor (1), to reduce it to a value below the max. permissible value when the power transistor is switched, with the switching pulse only fed to the base of the power transistor (1) when the voltage drops below the max. permissible value. Pref. an FET switch (2) is connected in parallel with the collector/emitter path of the power transistor, its gate receiving the switching pulses directly and its drain coupled to the base of the power transistor via a logic circuit (4) which delays the switching pulses. The logic circuit (4) may be controlled by a voltage measuring device (6) across the power transistor.

Title: Slip ring seal - with rustless sealing ring embedded in vol. changeable material, esp. silicone rubber, which forces sealing ring against bush
Inventor: MENKHOFF KARLHEINZ
IPC: F16J15/34
Filed: 1980-12-10
Abstract: Slip ring seal consists of a slip ring made of rustless material embedded in a material which is capable of changing its vol. and thus pressing the slip ring against the bush to be sealed. The material in which the ring is embedded is pref. shaped such that it has a lip which also impinges against the bush to form a double seal. Pref. the material of changeable vol. is of formula (I) or similar. The sealing ring is e.g. of stainless steel, bronze or sintered metal. Use of vol.-changeable material allows higher pressure to be exerted on the sealing ring than in prior art spring loaded systems, thus giving improved sealing.

Title: Radio relay system
Inventor: HANNI MANFRED ING GRAD
IPC: H04B7/15
Filed: 1981-03-18
Abstract: The invention relates to a radio relay system for a plurality of digital communications channels which are combined on a word-by-word basis in a time division multiplex frame (R) and modulated for transmission via a radio relay path (I, II) in suitable form onto a radio-frequency carrier. To achieve signal transmission which is largely resistant to external interference, while accepting a considerable restriction in traffic-carrying capacity, it is proposed to provide at least one communications channel (K11 ... K14, K11 ... K13) at the transmitting end in multiple form in a suitably distributed arrangement in the pulse frame and to evaluate this multiple transmission in an evaluation circuit (V) in the receiver (E) in time with the incoming pulse frame in order to identify a signal word with minimal or no interference. <IMAGE>

Title: Apparatus for treating contaminated raw water to give drinking water
Inventor: KOGLIN BERND DIPL PHYS DR
IPC: C02F9/00
Filed: 1981-07-01
Abstract: The apparatus is essentially composed of a pack unit (1) which contains a plurality of separate chambers (2), which can be closed by lids (3), into which chambers the chemicals (14) for water treatment are accommodated. In each chamber (2) is arranged a spring(97)-tensioned piston (4) which is connected to a release mechanism (5, 6, 7). For metering the chemicals (14) into the water to be treated, the pack unit (1) can be connected to a clockwork mechanism (12) which sequentially actuates the release mechanism (5, 6, 7) of the individual pistons (4). After it has been released, the piston (4) travels abruptly through the chamber (2) and ejects the chemicals situated therein into the water to be treated. This process is repeated sequentially in all chambers (2) in accordance with the time cycle preset by the clockwork mechanism (12). <IMAGE>

Title: Fuel delivery unit having a pump rotor revolving in a pump chamber
Inventor: KEMMNER ULRICH DIPL ING
IPC: F02M37/04
Filed: 1981-07-31
Abstract: A unit is proposed which serves for the delivery of fuel. The fuel delivery unit comprises a pump rotor which revolves in a pump chamber and on which the delivery pressure building up acts in an axial direction, because the delivery elements of the rotor are disposed on at least one of two rotor end faces which are parallel to one another and are arranged transversely to the rotational axis. The pump rotor is thus loaded in the direction of one chamber wall. In order to avoid chafing of the rotor edge zone on the chamber wall, there is arranged between the rotor and the chamber wall a spacer which is located in or near the rotation axis and whose diameter is smaller than that of the pump rotor. <IMAGE>

Title: Device for closing constructional seals on constructional parts
Inventor: DRAEGER GUENTER DIPL ING
IPC: E04B1/66
Filed: 1982-01-16
Abstract: A device for closing constructional seals on constructional parts has a clamping rail, with which the constructional seal is clamped directly on the constructional part and which has an upper longitudinal bead for receiving a sealing profile with an upper closing edge directed towards the constructional part, a plane central portion lying against the constructional seal and having perforations for fastening means, and a lower closing border lying against the constructional seal. In this arrangement, at least one further upper, longitudinally extending stiffening bead (4) curved outwards to the side facing away from the construction, is formed between the upper longitudinal bead (6) and the central portion (2), and the lower closing border is designed as a closing longitudinal bead (12) with inwardly bent-round lower closing edge (13, 14) pointing in the transverse direction of the clamping rail (1). Additionally, at least one lower, longitudinally extending stiffening bead (10), curved outwards to the side facing away from the construction, is formed between the closing longitudinal bead (12) and the central portion (2). Finally, the clamping rail is formed, together with all beads and the central portion, entirely as a roller-deformed section of metallic strip material. Advantageously, longitudinal, stiffening and closing longitudinal beads including their transitions are formed so as to merge into one another in undulating fashion. <IMAGE>

Title: Cupboard for the press-steaming of articles of clothing
Inventor: BROELLOS GUENTHER
IPC: D06F73/02
Filed: 1982-02-13
Abstract: There is a cupboard, in which a cupboard housing forms a steaming chamber (1) with a door (2), a carriage (9) carries a steaming dummy (15) and, with the door opened, can move together with the steaming dummy out of the steaming chamber (1) and into it again, and an additional hanging device (30) for attaching an article of clothing in the steaming chamber is provided. It is desirable, at the same time, that, along with an improved matching of the cross-section of the steaming dummy to the human cross-section, an improved filling of the steaming chamber with the inflated steaming dummy be achieved. This is achieved in that the horizontal cross-section of the inflated steaming dummy (15) is elongate in an essentially oval-like manner, the horizontal cross-section of the steaming chamber (1) is rectangular, the moveability of the carriage (9) is rectilinear, the steaming chamber (1) is equipped with a second door (4) and the hanging device (30) is provided on the ceiling (29) of the steaming chamber. The cross-section of the steaming dummy is now matched in an improved manner not only to the human cross-section, but also to the cross-section of the steaming chamber, with the result that the ready-pressed articles of clothing are better matched to the human form and the utilisation of the space of the steaming chamber is improved considerably. <IMAGE>
