Patent DE-3735047-A1 (DE)
Title: Device for producing bottom-fold bags
Inventor: GEYER HERBERT
IPC: B31B50/00
Filed: 1987-10-16
Abstract: In bulk-goods packaging machines, which are equipped with a (shaping) mandrel wheel, the blank is first laid around a long side in a U-shape, then the side tongues are folded, and finally the bottom is produced on the end of the mandrel. In this method of production a three-layer bottom generally results. If, however, the blank is first folded in a U-shape about the end, a bottom-fold bag with a single bottom results, which means a lower packaging materials requirement. In order to be able to begin the shaping process of the blank on the end of the mandrel, a packaging material table is arranged parallel to the underside of the mandrels so as to be rotatable upwards through 90@ in front of the end of a mandrel. The U-folders are designed as tapered rolls movable on both sides along the mandrel on a circular path and rotatable about their taper axis, and the drive is designed as a multi-part Geneva drive. This device may favourably be installed in bulk-goods packaging machines in which the prepared button-fold bags are immediately filled and closed. <IMAGE>

Patent DE-3742342-A1 (DE)
Title: Drive for chain-operated operating means with separate load compensation and overload protection
Inventor: HENKEL EGON DR ING
IPC: E21C29/14
Filed: 1987-12-14
Abstract: For chain-operated operating means in underground mining, a drive is provided, in which the overload protection arrangement and the load compensation arrangement are in each case designed as a separate and separately mountable assembly. Both arrangements can then, separately or built together, be assigned to the asynchronous motor and the gear at more or less any place. The load compensation arrangement is in this case preferably a controllable motor and a self-locking worm gear. As a result, it is possible to control one of the drives in such a manner that the chain starwheel speed of the respectively overloaded asynchronous motor is reduced, as a result of which a corresponding load compensation arrangement is required on only one of the drives. <IMAGE>

Patent DE-3804859-A1 (DE)
Title: Sprung connecting rod
IPC: F02B75/32
Filed: 1988-02-17
Abstract: A sprung connecting rod is presented, the object of which is first of all to gently and flexibly absorb the hard reactions of the combustion explosions from the connecting rod bearings, secondly to store the forces taking effect in its own spiral windings in the form of spring tension and to deliver this in full, without loss, back to the crankshaft even before the end of the power stroke. Furthermore, to ensure that, on the intake stroke, the cylinder can be filled with fresh gases over its entire length and that on the exhaust stroke the piston head is driven right under the cylinder cover, thereby sweeping the entire cylinder chamber free of waste gases. It therefore goes without saying that no compression and combustion chamber at all is allowed for in the sprung connecting rod method, rather this forms itself on the compression stroke due to the fact that the gas medium is compressed by the compression spring of the connecting rod thereby forming the combustion chamber. <IMAGE>
Patent DE-3807035-A1 (DE)
Inventor: KIEFER KLAUS JUERGEN
IPC: B43L9/04
Filed: 1988-03-04
Abstract: To dispense with the so-called analog adjustment of a compass by comparison between the measuring point of the compass and a graduated rule and to enable the compass to be adjusted by electronic means, one of the branches (10, 20) or one of the supporting parts (11, 21) of the compas has a distance-measuring arrangement (22; 122; 222) which determines its distance from a reference measuring surface (23; 123; 223) situated on the opposing branch (10, 20) or supporting part (11, 21). This distance-measuring arrangement automatically determines the distance between two supporting parts. The measured distance (1) between the distance-measuring arrangement and the reference measuring surface corresponds, allowance being made for a given basic difference, to the distance between the stationary point and the tracing point of the compass. For industrial application, the distance-measuring arrangement can, for example, be provided with a memory in which given adjustment values can be stored. When the compass is to be adjusted according to a certain value, a display for an optical or acoustic signal indicating optimal adjustment of the compass according to the stored value can also be provided.

Patent DE-3813166-A1 (DE)
Title: Water/air mixing valve
Inventor: MATEJA ERNST
IPC: B01F5/00
Filed: 1988-04-20
Abstract: In a water/air mixing valve, a water valve (2) and an air valve (3) are arranged upstream of an entry (37) of a water conduit (9, 20, 27, 14, 29, 37) into an air conduit (41, 49, 57). Each of these valves has a closing element (19, 20 and 48, 49, 54 respectively) which is loaded in the closing direction by a compression spring (25 and 53 respectively) and, in a cylinder space, has a piston (19 and 48 respectively) which is acted upon in the opening direction by the pressure of the other medium in each case, the valve thus operating only in the presence both of air pressure and water pressure. The said pistons (19 and 48 respectively) of the water valve (2) and of the air valve (3) are furthermore acted upon (31 and 60 respectively) in the closing direction by the pressure prevailing at the outlet (45) of the mixing valve. As a result, they are forced back into the closed position when back pressure occurs. <IMAGE>

Title: Equipment for gasifying pulverised coal
Inventor: GUDYMOV ERNEST DR ING
IPC: C10J3/46
Filed: 1988-05-05
Abstract: The invention relates to equipment for gasifying pulverised coal with the use of steam and oxygen-containing gas, and it can be used in the chemical industry for generating hydrogen and carbon monoxide from solid fuels. It is the object of the invention to design the equipment under the conditions of the partial oxidation of fuels under pressure in such a way that coals with a low-melting ash can be employed. According to the invention, the equipment comprises a pressure vessel with heat insulation, branches (3, 4) for discharging the generator gas and the granulated slag, a pulverised coal burner (5), an overflow pipe (6) for maintaining the water level, a refractory lining wall (8), horizontal gas ducts (9), a gas-tight tube-cooling screen (10) with reversing loops (11), an inlet and outlet collector, a steam distributor (14), steam pipes (15) and the steam nozzles (16). <IMAGE>
Patent DE-3816811-A1 (DE)
Title: High-voltage, gas-blast switching chamber
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/91
Filed: 1988-05-14
Abstract: It is intended to optimise the system for interrupting the arc current in a stationary double-nozzle arrangement (2, 3) composed of electrically conductive material and in which the extinguishing gas is compressed by means of an annular piston (5) within a compression cylinder (6) which also partially represents the switching chamber. To this end, the annular piston is connected especially by means of longitudinal walls (7) to the contact (4) to form a structural unit. The switch drive then acts thereon via operating rods (19) which are in the form of forks and are arranged outside the gas outlet tube (31). In the course of functional extension of the longitudinal walls, the switching-off arc can thus be stabilised axially in the space between the nozzles if the nozzle separations are large as a function of the operating voltage. The use of a special nozzle body (3) offers particular advantages at high operating voltages, an electrically insulating inlet part (3a) being placed on the electrically conductive extension part (3b) of said special nozzle body (3). In order to make it easier for the switching-off arc to commutate from the compression space (8) into the nozzle (3), the nozzle inlet part is provided with gaps (3c) through which gas and arcs can pass. As a result of their relative arrangement, the longitudinal walls assist the movement of the arc through one of these gaps. <IMAGE>
Patent DE-3817890-A1 (DE)
Title: Coil
Inventor: SAKAMOTO YUKIO
IPC: H01F27/29
Filed: 1988-05-26
Abstract: The present invention relates to coil structures which contain a core and a wound wire provided in the core, which are used for the purpose of a high-frequency inductor coil. The coil contains a base which has a symmetrical projection, in order to fasten it stably on the substrate during assembly, a post which projects from the base, an arm which is carried by the post, a slot which is cut parallel to the arm and is open on the opposite sides of the post, and a wire which is wound on the arm, the terminals being led outwards from the core through the slot. On assembly, the wound wire can be laid on the arm of the core and the terminals are led outwards through the slot, which forms the operation easy and efficient to perform. Since the projection of the core base forms the separation between the substrate and allows the air to enter through the terminal wire installation holes, the soldering of the terminal wires onto the substrate can be carried out satisfactorily and automatic assembly with the substrate can also be adapted. <IMAGE>

Title: Valve device for a brake system with slip control
Inventor: JUNG CHRISTOPH
IPC: B60T8/44
Filed: 1988-05-31
Abstract: The vacuum chamber 17 is connected to a vacuum source 49 by way of a non-return valve, inserted into a line 61 of small cross-section, and by way of a check valve, which is normally closed and is inserted into a line 60 of large cross-section. Non-return valve 59 and check valve 57 are arranged in parallel. In order to build up pressure during the control cycle, the valve 18 and 18' is opened and the chamber 17 ventilated. A pressure is produced in the chamber 17, since the quantity of air fed in by way of the narrow cross-section of the line 61 cannot be sucked out rapidly enough. For the renewed build-up of pressure, the valve 57 is opened so that the air present in the chamber 17 can be led off rapidly by way of the large cross-section of the line 60. <IMAGE>
Patent DE-3820187-A1 (DE)
Title: Elimination of hydrogen from a post-accident atmosphere of a nuclear power station
Inventor: WIESEMES JOHANNES DR
IPC: G21C9/00
Filed: 1988-06-14
Abstract: The elimination of hydrogen from a post-accident atmosphere of a nuclear power station is carried out by means of combustion of the hydrogen with the aid of electrical sparks in a partial volume of the safety container secure against the propagation of explosion. The experimental proof of the effectiveness of the method has already been furnished by the inventor in suitable experimental arrangements.   The invention uses a suitable combination of known devices, in detail sparking plugs and miners' safety lamps which have long since been tried and tested:     - sparking plugs in internal combustion engines   - explosion-safe miners' lamps with open flames. A small partial volume of the gas space contains a spark-gap and is closed off by means of a sieve-like metallic grid from the remaining gas space, the grid safely preventing propagation of an explosion-like gas reaction into the remaining gas space outside the partial volume. Mechanical damage or overheating of the metal grid leads, according to the invention, to an interruption of the ignition voltage and thus of the ignition sparks. The ignition voltage originates, according to the invention, in an induction coil whose primary pulses are generated outside the safety container. The method and the device can be used equally well for the elimination of explosive gas mixtures in chemical installations.
