Title: Method for calculating the resultant state of a relay ladder circuit and sequence controller for carrying out the method
Inventor: SASAKI JUNICHI
IPC: G05B19/05
Filed: 1981-04-16
Abstract: The relay ladder circuit exhibits n rows and m columns, n and m being integral numbers. The resultant state depends on the switched state (opened or closed) of the contacts of the relay ladder circuit. Contact data which relate to the type and the operation of the contacts of each column of the relay ladder circuit are stored in a first memory (101). Branching data which relate to the type of the branching contact of each column are stored in a second memory (102). Logic operations are carried out by means of a gate circuit (111 to 116, 121 to 124) on the contact data and on the branching data of each column, beginning with the first row to the last row, in such a manner that, at the end, all columns of the relay ladder circuit have been subjected to the logic operations. <IMAGE>

Title: Cube with through bores, and rods which fit into and are intended for insertion into the latter
Inventor: SCHWARZ JOACHIM DIPL ING
IPC: A63F9/08
Filed: 1981-05-19
Abstract: Toy for one person. It is composed of a cube which is provided with through bores which extend from four sides (not from the top and bottom), are arranged in a plurality of "storeys" and intersect one another at right angles in each storey. These include rods (one rod per bore) which can be inserted into the bores. The rods can have different colours (one quarter each of the same colour) and a "head" which prevents complete insertion of the rods into the bores of the cube. The inventor has, by way of a solution, provided drawings in which the cube is broken down into individual horizontal projections ("storeys"), for which projections a combination of rods is determined in each case. Once all the storeys have been processed, the lengths of all the rods are ascertained in their respective colours. The player must slide the rods into the bores of the cube in such a way that all the rods are inserted in the cube up to their heads and that only rods of the same colour are arranged on each side. One possible solution is the combination shown in the inventor's drawing. It would also be conceivable to exchange storeys or individual rods. <IMAGE>

Title: Appliance for the paring of soft leather
Inventor: SCHLIEBEN ULRICH VON
IPC: C14B1/16
Filed: 1981-05-21
Abstract: The invention relates to a leather-paring appliance consisting of a frame having a horizontal roller, above which an adjustable knife holder with a knife blade is mounted, the leather, with its flesh side facing the knife, being drawn under tension over the roller and thus being split or pared by the blade, characterised in that, during the setting of the working thickness or during the lifting in order to introduce the leather workpiece, the knife holder is maintained in its position relative to the roller, for example parallel, by means of a parallel guide, and in that its position relative to the roller can be adjusted on this parallel guide, as well as in that the receptacle of the knife holder has, beyond its centre of rotation located behind the knife holder, a tail-like extension bearing against an adjusting screw which adjusts the working thickness of the knife above the roller. The parallel or angular position of the knife in relation to the roller can be adjusted by means of a device which engages on the parallel guide and which clamps the head of the knife holder by means of a screw in a slot of the parallel-guide spring, or by means of an adjusting spindle which fixes the position of the knife-holder head relative to the parallel guide. <IMAGE>

Title: Process and device for extruding a candle strand
Inventor: HERRHAMMER PETER ING GRAD
IPC: B29C48/465
Filed: 1982-07-02
Abstract: For extruding a candle strand a raw material comprising a powdery or granular wax or paraffin is transformed into a plastic state by the continuous application of pressure by a rotating transport element, for example consisting of a pair of toothed or vaned wheels (6), compressed and this moulding compound is pressed through a mould matrix to form the finished strand. At the same time as the strand formation, a candle wick (23) is also inserted into the centre of the candle by means of a wick tube (20) projecting into an extrusion chamber (10). The rotating transport element provided for transporting and compressing the raw material is disposed in a transport chamber formed below a supply tank (2). A compression chamber (8) and an extrusion chamber (10) having a mould matrix (12) at its outlet end adjoin said transport chamber. These chambers are expediently formed in a block-shaped extrusion housing (1), on the outer wall of which the mould matrix (12) is attached, so as to be exchangeable, in order to close the extrusion chamber opening. <IMAGE>

Title: Economy switching device in circuits especially for hotel rooms
Inventor: BREHM GEB EHRMUTH
IPC: G08B17/00
Filed: 1982-07-28
Abstract: In order to suppress current wastage, for example in hotel rooms, it is proposed that each hotel room have a dedicated circuit = room circuit which, for example, is connected in/to the main circuit or, for example, in parallel with the main circuit; means such as contact pins (34) having switching boxes (40) are proposed in order to interrupt this room circuit when the guest leaves the room, and to close the room circuit when he enters the room. Room keys (27) (in the sense of a security card or the like) are also proposed as means, which operate the corresponding, for example two, contacts (9, 14) for the room circuit on opening and closing, that is to say the room circuit is opened or closed. For safety, a further so-called safety circuit can be provided in the room. If gas or smoke develops, or flames occur, then an alarm contact is closed and the hotel management know that, for example, a fire has broken out; in this case it is possible to make the room in which this has occurred identifiable on a switchboard. <IMAGE>

IPC: G01M1/02
Filed: 1982-11-12
Abstract: In an unbalance compensation device for measuring the unbalance of a component (designed as a rotary part) in two measuring planes which run at a distance from one another and to which the device can be adjusted by means of a surface change-over switch for the compensation of the unbalance, the machine stoppage due to the traditional surface change-over switches becoming defective is eliminated, the manipulation is simplified and the downtimes are reduced by such a surface change-over switch being used in the device which is connected to the output of the angularity-difference indicator of the analysing unit so that it automatically switches over to the other measuring plane at the appropriate time. The surface change-over switch is preferably an electronic switch, the acceptance condition of which is a 0-signal from the angularity indicator, but the switching signal of which is a minimum angularity difference set beforehand. The switch is preferably interconnected with indicating lamps which indicate the measuring plane.

Title: Exhaust gas heat exchanger
Inventor: LUEBKE PETER
IPC: F28D21/00
Filed: 1983-01-22
Abstract: The invention relates to an exhaust gas heat exchanger having a central exhaust gas shaft and a tube, which penetrates this shaft, for a heat-absorbing medium, as well as an admixture of exhaust air into the shaft upstream of the heat exchanger. It is the object of the invention to provide such an exhaust gas heat exchanger of high efficiency. It is proposed for this purpose that the tube is provided with an exhaust gas guide (7) which imparts to the exhaust gas a component movement in the direction of the inside of the circumferential surface (9) of the exhaust gas shaft (1), and that the shaft has the entrance opening (14) for the exhaust air on its periphery. It is achieved hereby that the exhaust gas flows onto the inner circumferential surface of the heat exchanger, it being the case that it condenses, on the one hand, and that, on the other hand, water that has already condensed is precipitated on the inner circumferential surface. <IMAGE>
