Patent DE-3324875-A1 (DE)
Title: Apparatus for the cleaning of gases
Inventor: KARR DIETER
IPC: B01D51/00
Filed: 1983-07-09
Abstract: An apparatus is proposed for the cleaning of gases in which an agglomeration of the particles to be separated out takes place due to an electrical field (E). The agglomerates can be separated out particularly easily in mechanical separators (12) on the basis of their mass and their size, for example in a simply constructed cyclone. The process which is particularly suitable for the cleaning of exhaust gases from fossil fuels, is particularly effective when the number and the bulk of the agglomerates formed at the outlet of a coagulator (11) can be increased, which takes place in a particularly easy manner by the recycling (19,20) of coagulation seeds in the form of previously formed agglomerates to the inlet of the coagulator (11). <IMAGE>

Title: Method of determining the notched impact strength of a metallic specimen at low temperature
Inventor: LAUMANN WERNER DR
IPC: G01N3/30
Filed: 1983-10-07
Abstract: To determine the notched impact strength of a specimen of a metallic material at low temperature, the specimen is first placed in a container which encloses it on all sides, which is composed of materials with a lower notched impact strength, whose end faces also serve to support the specimen and which has a cavity into which a suitable coolant is introduced from outside via a hollow-needle-type inlet. The cooled specimen is then suddenly stressed by means of the pendulum of a pendulum ram impact testing machine, and in this process the container is smashed at the same time. In order to ensure a sufficiently long time for the actual measurement, the invention provides for the specimen (2) to be placed in a container (3) which is made up of two moulded parts (5, 6) composed of a hard foamed plastic material with closed pores and mechanically joined with a taping (15) at its common joints (9), the cavity (4) for the coolant (M) being sealed. <IMAGE>

Title: Device for recording goods, particularly price-calculating scales with printer
Inventor: LUFEN KARL-JUERGEN
IPC: G07G1/00
Filed: 1983-12-15
Abstract: In a device comprising a terminal for recording selectable quantities of goods from an assortment of predetermined articles, article keys are provided in a read-out keypad, which keys read out article data stored in a memory and display these on a display or on a printer. To obtain a device which is simple and easy to operate, it is proposed to convert this read-out keypad into an input keypad by removing a holding plate holding together the mechanical members of the read-out keypad and providing the membrane, located underneath, with labelling of the symbols with which the input keypad is effective for programming the various article keys. For this conversion of the keypad, a control device is used which, in addition, can handle other functions.

Title: Rotating cropping shears for rolled rods
Inventor: PECHAU GERHARD DR ING
IPC: B21B15/00
Filed: 1984-02-10
Abstract: The invention relates to a rotating cropping shear for high-speed rolled rods, which shear cuts off the qualitatively unsatisfactory beginning and end portions in high-duty rod rolling mills and in which the stock passes through a swivelling tube, between two cutter heads and through a delivery part having two separate channels. The aim of the invention is to avoid interference with the rolling line due to the parting cut and hence to increase the operational reliability of cropping shears of the type stated. The object on which the invention is based is therefore to design the cutting operation between the rotating cutter heads in the following delivery part in such a way that the required motion components in the cutter heads and in the delivery part lie in one direction. According to the invention, the object is achieved by the fact that the cutter head diameter increases in the cutting plane of the cutting heads, from the front face of the cutter to the opposite, rear side of the cutter, and preferably runs out at the level of the rear top edge of the cutter. <IMAGE>

Title: Process and apparatus for producing a constant mass flow rate or volumetric flow rate gas/solid particle free jet of defined velocity
Inventor: LESCHONSKI KURT PROF DR ING
IPC: B01F23/30
Filed: 1984-03-02
Abstract: In a process and an apparatus for producing a constant mass flow rate or volumetric flow rate gas/solid particle free jet (7), in which the solid particles having a size of in particular less than 50  mu m are completely and uniformly dispersed, a compressed solid particle mass stream (8) of constant density and constant cross section is produced with the aid of a rotating metering groove (2) and is then completely sucked into a closed flow channel and accelerated and dispersed in an injector (9). The gas/solid particle mixture formed during this is given off from the flow channel as a free jet (7). In order to improve the dispersion, in particular, of very fine particles (down to a few  mu m), it is provided that the gas/solid particle mixture, prior to discharge from the flow channel, is repeatedly deflected against at least one baffle (17), in particular on a plurality of sequentially arranged inclined baffles offset in a zigzag shape which are impacted sequentially (baffle cascade (15)). <IMAGE>
Patent DE-3408239-A1 (DE)
Title: Process for the removal of high-boiling and polymer fractions from the acetic acid fraction in vinyl acetate preparation
Inventor: HEY HANSJOERG DR
IPC: C07C51/44
Filed: 1984-03-07
Abstract: The invention relates to a process for the removal of high-boiling and polymer fractions from the acetic acid fraction which is obtained during the separation of the crude product from the reaction of acetic acid, ethylene and oxygen on a catalyst in the gas phase to give vinyl acetate. The acetic acid is distilled off from the acetic acid fraction down to a residual content of 30 to 95% by weight. At least sufficient water is then added to the residue such that an acetic acid-containing aqueous phase and a high-boiling and polymer-containing tar phase is formed. Instead of first distilling off the acetic acid and then adding water to the residue, the acetic acid can also be distilled off with addition of water or water vapour such that a high-boiling and polymer-containing bottom having a water content of 3 to 30% by weight remains.

Title: Protected event data display
Inventor: HECKMANN ROLF DIPL ING
IPC: G08B5/36
Filed: 1984-04-09
Abstract: To display the operational events of a plant to be controlled and/or to be monitored on as small as possible a display area, it is provided to illuminate, as required, the event fields, associated with the individual plant elements, of the display area of the optical fibres (LL). These optical fibres (LL) are to be illuminated via associated light-emitting diodes (LED). Each light-emitting diode is associated with an event line (ML) via which the operating state of the light-emitting diode is to be transmitted to a remote control station. This event line is connected, in the vicinity of the in each case associated light-emitting diode, via a high impedance (via R) to a potential (H) which identifies the deenergised state of the light-emitting diode. If the light-emitting diode is switched on, a potential (L) identifying the energised state of the light-emitting diode is impressed on the event line (ML). This potential is taken either from the feed circuit of the light-emitting diode (LED) between a switch (S) and the light-emitting diode, via an optocoupler (OK) controlled at the input end by the feed current of the light-emitting diode or switched via an optocoupler which is controlled by the light-emitting diode itself. <IMAGE>
Patent DE-3414195-A1 (DE)
Inventor: DEMOULIN JEAN
IPC: E21C35/22
Filed: 1984-04-14
Abstract: The rotor of a cutter for removal of material from a mine face has a large number of externally mounted bits each of which is adjacent to a discrete spray nozzle serving to discharge one or more streams of water at a pressure in the range of several thousand bars. The nozzles receive water from conduits which are installed in an annular chamber between the skirt of the substantially cup-shaped rotor and the adjacent end portion of the drive shaft for the rotor. Groups of conduits receive pressurized water from manifolds which are installed in the chamber and each such manifold receives pressurized water from a discrete conduit which, in turn, receives pressurized water from a distributor rotating at the discharge end of a stationary pipe in an axial bore of the shaft.
Patent DE-3419514-A1 (DE)
Title: Process for reducing the heating and cooling water requirement in thermodynamic absorption cycles
Inventor: FOERSTER HANS DR ING
IPC: B01D19/00
Filed: 1984-05-25
Abstract: The invention relates to a process for heat recovery and saving cooling water in steam-heated, thermodynamic absorption cycles, preferably in absorption refrigeration units having two desorption stages. The aim of the invention is to replace the solution recycling for the regenerative utilisation of the heat content of weak solutions by a more effective process and, in this case, to cool the weak solution more intensively and to considerably reduce the external heat requirement of the desorber. According to the invention this is achieved by withdrawing the strong solution to be degassed from the desorber at a defined point, degassing it in an external horizontal trickle degasifier with the aid of the heat content of the weak solution or other heat transport streams and then returning it to the desorber separated into liquid and vaporous phases. The invention can be used in all thermodynamic absorption cycles, preferably in absorption refrigeration units having two desorption stages. <IMAGE>
Patent DE-3422049-A1 (DE)
Title: Fence post with lockable fastening elements
IPC: E04H17/10
Filed: 1984-06-14
Abstract: The invention relates to a plastic hollow profile which is designed in such a manner that automatically locking fastening elements can be fitted. The hollow profile can be provided with reinforcing elements. The fence post designed as a hollow profile exhibits groove-like formations with conical undercuts on its longitudinal sides. Fastening elements with claw-like tips lock into these groove-like recesses with conical undercuts. By virtue of the conical formation of the undercut region of the grooves in the profile and of the claw-like formation of the tips of the spring element, the latter is fixed in place of its own accord. The spring element is, moreover, provided with a slot-like punched part, as a result of which said element can be pressed down via a pre-tensioned tensioning wire, the latter thus being fixed in place. Furthermore, the spring element is designed such that, by the front of the latter being formed like an arc of a circle, a round bar can be provided for the additional securing of the wire netting.
