Title: Reverse loop circuit for model railways - supplies current either through two insulated running rails or through overhead cable and one running rail
Inventor: KUTTER FRITZ DIPL ING
IPC: A63H19/24
Filed: 1977-12-02
Abstract: Revrse loop circuit for model railways is such that the current supply of the locomotive vehicles takes place either through the two running rails insulated against each other or alternatively through an overhead cable and one of the running rails. Both rails of the reverse loop curve are subdivided by four separating points into three zones electrically insulated against each other. The current source of the running rails is connected through a polarity switch of a relay with the rails of the main track and through a polarity switch of a second relay to the centre zones of the rails of the reverse loop curve. The other zones of the rails dependent on the actual position of the relays are connected to the plus or minus pole of the running rail current source and are connected only to one of the relay coils.

Title: Fire extinguishing compsn. comprising granulated mineral material - used with heat resistant adhesive, e.g. water glass, to cover solid surface
Inventor: JAUROS ENSI
IPC: A62D1/00
Filed: 1978-07-11
Abstract: A process for extinguishing materials on fire, and/or for preventing materials or objects from catching fire, involves covering the surface of a solid material with an incombustible, fibrous, granulated or powdered substance, partic. a granulated mineral wool. This substance adheres to the surface of the object on fire by means of a heat resistant sticky substance. The granulated mineral matter can be projected farther than e.g. H2O or a heavy foam. The mineral wool can be stored indefinitely, and when usef forms a thermally insulating layer which limits the heat radiation. The heat resistant sticky substance is partic. a glue of the sodium silicate type, e.g. a soluble glass. It is pref. fed, in liq. form, to a jet of air carrying along the incombustible substance. 4 1 soln. of soluble glass can be used for 100 kg granulated mineral wool.

Title: Structure transfer of semiconductor circuits onto glass plate - defines coarse and fine structures and exposes differently photosensitive film through both structures
Inventor: LINDERT GEROLD
IPC: G03F1/00
Filed: 1978-08-11
Abstract: The structures (2, 3) of semiconductor integrated circuits are transfered onto a glass surface (1) by projecting light beams (4) through structure master (1') containing transparent partial regions (2', 3'), the masters being spaced appropriately from the glass surface. The latter is coated with a photosensitive film which, after exposure, is subjected to photolithographic steps to provide the desired structure in the film and the underlying glass surface. In order to transfer closely adjacent coarse and fine structures, these structure are each defined by a separate master which is used for different intensities. The intensity rating is chosen in such manner as to bring as closely together as possible the exposure intensities. The process may be also used for producing masks for integrated circuits manufacture.

Patent DE-2844706-A1 (DE)
Inventor: HENTSCHEL MICHAEL DR ING
IPC: G05B13/04
Filed: 1978-10-13
Abstract: In order to avoid direct temperature measurements, which are difficult to carry out and have to be carried out frequently, the heat budget of an electrical apparatus or machine can be simulated - in order to control protection processes - using an electrical circuit which uses a thermal model (R1, R2, C1, C2) to represent the heating of the apparatus or machine by charging (controlled by the power consumption of said apparatus or machine) at least one capacitor. Improved matching to the conditions to be simulated by making known simple models more complicated can be carried out only to a limited extent and is uneconomic. A plurality of supply circuits are thus provided for the model, whose characteristics can easily be matched to the respective conditions. In particular, a first circuit supplies a capacitor charging current (Io) as soon as the apparatus or machine draws current, while at least one second circuit supplies such a current (Iz) only in a sub-region of the possible values of the current drawn by the apparatus or machine. <IMAGE>

Title: Stackable pressed pallet construction - has boss integral with connecting rib wider at bottom than top
Inventor: MUNK EDMUND
IPC: B65D19/00
Filed: 1978-10-20
Abstract: The pressed pallet is made of a non-distorting mixture of fibres containing ligno-cellulose and a heat-hardening binding agent, formed in one piece by pressure and heat. Its hollow trough-secion feet widen towards the top, and are joined by trough-section ribs, so as to stack together empty and occupy the minimum of space. It has a stacking boss integral with a connecting rib, whose length and breadth on the underside are greater than at the top. The design avoids the pallets jamming together when stacked and also avoids damage to them in handling.

Title: Adhesive closure for envelopes - is capable of providing either repairable or non-repairable type of closure for use either for printed matter or for letters
Inventor: PORTH ERWIN
IPC: B31B160/10
Filed: 1978-11-15
Abstract: Repairable and irreparable adhesive closures are formed for despatch bags, letter envelopes and other packages. There are two contact surfaces and there is an adhesive layer on one of the closure surfaces. This faces the other surface opposite or from an adhesive layer on each of the two closure surfaces. A further contact plane is positioned at a distance from at least one of the two contact surfaces (5, 7) and largely parallel to this contact surface on the coordinated closure surface which can be brought into an adhesive contact with the opposite contact surface by a light contact pressure to make a repairable adhesive closure suitable for printed matter. To form an irrepairable adhesive closure used especially for sealing letters the additional contact plane (9) together with the contact plane (7 or 5) is brought into an adhesive contact with the contact plane opposite by the application of a firm contact pressure.

Title: Optical data transmission system wavelength demultiplexer - has junctions with mirrors controlling paths to detectors mounted on narrow band filters
Inventor: WINZER GERHARD DR
IPC: H04B10/00
Filed: 1978-11-29
Abstract: The wavelength demultiplexer for an optical data transmission system uses junctions which split the signals into two paths corresponding to two set of wavelengths. Each set then passes to a further junction which splits each set into two further sets. The resulting wavelengths are then passed through narrow band filters. Preferably a junction consists of three channels (201 to 203) through a glass fibre body with an inlet end and two arms (20, 20') at right angles to each other. These channels pass through sloping reflective surfaces (210, 220) which each split the signals into two paths. Each path terminates in a narrow band filter (26, 26') and a detector (206, 261) for the corresponding waveband to be passed, the detectors being directly mounted on the filters.
