Title: Furnace flue gas cooling by air dilution - reduces temp. below that required for toxic dioxin formation
Inventor: BRUENGER ALFRED
IPC: F27D17/00
Filed: 1990-06-08
Abstract: System for discharge of flue gases, especially from electric arc smelting furnaces. Typically such a furnace (11) provided with at least one flue, is connected to a sealed vent system; the general foundry area also is provided with ducted fume extraction (19). In the invention, the furnace flue length is made as short as possible and connected into the fume extraction ducting so that the hot furnace gases are cooled by mixing with the fume extraction air flow prior to passing to the filtration unit. Alternatively, the furnace gases may be indirectly cooled by the fume extraction air flow through a heat exchanger.  Preliminary cooling may be provided by installation of a section of water cooled ducting at the furnace outlet. USE/ADVANTAGE - Smelter operations. Claimed that rapid  cooling of furnace gases, typically discharged from a water cooled flue section at 250-400 deg.C. can be achieved to 40-130 deg.C. by cool air dilution, thereby reducing the formation of toxic Dioxin compounds.

Patent DE-4100920-A1 (DE)
Inventor: GREISSINGER DIETER DR
IPC: A23K40/35
Filed: 1991-01-15
Abstract: 2.1 Active agents such as feed additives and drugs are often to be released in a delayed manner or slowly after their oral administration. In particular in the case of ruminants, little or none should be released in the rumen. Appropriate encapsulations are expensive and, in particular for administration of relatively large amounts of product, are unsuitable and too costly. Known encapsulations of this type also have the disadvantage of a questionable physiological acceptability and/or are not permitted. 
<??>2.2 The novel encapsulation contains relatively thin regions and/or predetermined breaking points, which accelerate the release in comparison to an essentially uniform coating. Angular particulars such as pellets are preferably encapsulated, the encapsulation being formed in such a manner that the encapsulation can break at the edges after the oral administration. Encapsulations are preferably composed of two layers, the inner layer containing a filler plus film-forming agent and the outer layer only containing film-forming agent. 
<??>2.3 The encapsulation is suitable for protected administration of active agents for nutritional purposes, for example methionine, or for medical, in particular veterinary medical, treatment, in particular of ruminants.

Title: Pollution-free disposal of hospital waste - by collecting waste in filter container, steam sterilising and discharging waste and steam into incinerator
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/02
Filed: 1991-03-15
Abstract: After collection at its point of origin into a sealed container, hospital waste material is sterilised by steam before the container and its contents are taken to an incinerator. Steam used for sterilisation is absorbed by a chemisorption filter. When the mobile container reaches the incinerator, it is automatically connected thereto, esp. by a water cooled fitting; the container is topped by hydraulic mechanism to discharge its contents into the combustion zone, which also receives steam liberated from the  filter, to be totally consumed within the incinerator. After tipping back to normal position, the container resumes its return journey to the waste delivery location. ADVANTAGE - Simple process prevents atmos. pollution and provides no risk to personnel.
Patent DE-4108711-A1 (DE)
Inventor: SCHNEIDER ECKHARD DR
IPC: F16F9/08
Filed: 1991-03-16
Abstract: An air spring has a pressurisable elastomeric air spring bellows and an additional air volume which can be coupled to the bellows volume. In order to achieve, with low technical outlay, a rapid modification of the effective air volume and thus a rapid and essential change of the spring rigidity, the additional air volume (16) can be connected to and disconnected from the bellows volume. The air spring bellows (10) is partially filled with a medium (13) which is less compressible than air. The incompressible volume portion of the filling medium (13) corresponds at the most to the volume which the air spring bellows (10) has in the operationally applied sprung end position. <IMAGE>
Patent DE-4112280-A1 (DE)
Inventor: MAERZ PETER DR
IPC: A61M25/00

Title: Processing cleavage gases from thermal cleavage of 1,2-di:chloro-ethane - by cooling the hot gas mixt., sepg. into gas and liq. phases, filtering coke out of the liq. phase, back-washing filter with organic liq., etc.
Inventor: PERKOW HELMUT DIPL CHEM DR
IPC: C07C17/38
Filed: 1991-10-02
Abstract: Process is for removing coke from the cleavage reaction gas obtd. by thermal cleavage of 1,2-dichloroethane to vinyl chloride at 480-540 deg.C and a pressure of 15-25 bar, opt. followed by cooling to 180-280 deg.C in a heat recovery stage, whereby the reaction gas mixt. is sepd. in a further cooling zone into a gas phase and a liq. phase which contains the coke, the coke is removed from the liq. phase in a filter and the gas phase and the filtered liq. phase are worked up together in a rectification zone, such that the coke is backwashed out of the filter with an organic liq. and the coke is comminuted in the organic liq. in a communition zone and the resulting dispersion is incinerated in a combustion zone. USE/ADVANTAGE - The process facilitates emptying of the filters used to remove the coke formed during the thermal cleavage, and allows the sepd. coke, which is contaminated with chlorinated hydrocarbons and cannot therefore be dumped, to be incinerated with recovery of HC

Title: Security marking of goods as precaution against theft from shops etc. - by applying silica in liq. medium, e.g. printing ink, to e.g. packaging, and using the silica as passive sender in alarm system
IPC: G08B13/24
Filed: 1991-10-31
Abstract: Material for marking goods as a precaution against theft is based on silica in a liq. medium suitable for direct application to the goods or to the packaging for these. USE/ADVANTAGE - The silica material is incorporated e.g. into an ink used for printing onto the packaging used for goods for sale in shops, etc., or in the case of textile materials the silica can be incorporated into a liq. compsn. printed directly onto the material. The pyroelectric and piezoelectric properties of the silica are utilised by placing a sender and receiver in the vicinity of the exit from the shop, so that the sender excites the silica marking on the goods or packaging such that it emits a signal in the ultrasound region which is picked up by the receiver and sounds an alarm. The silica used as passive sender can be incorporated directly into the printing on packages or textile goods and is therefore virtually invisible to potential thieves. It is also impossible to remove the silica marking without physically cutting it out, which would render the goods useless. The system therefore offers greater security against theft than prior art systems in which a removable tag or the like is attached to the goods for sale as passive sender
Patent DE-4141793-A1 (DE)
Title: Kingpin lubrication for powered steering axle - has large volume lubricant reservoir by linking bearing by lubrication duct and with common greasing nipple
Inventor: KATZENSTEINER JOSEF ROMAN
IPC: B60K17/30
Filed: 1991-12-18

Each bearing has a volume for a lubricant reservoir (9) and both bearings on each wheel are linked by a lubricant duct (15). This increases the lubricant volume and enables lubrication via one greasing nipple on each wheel. The lubricant linking line can be incorporates inside the axle support, either by boring or by the inclusion of a pipe duct during casting, or via an external pipe. ADVANTAGE - Simplified lubrication system, long life bearings, reduced maintenance periods.

Title: Synchronised clock pulse generator with delay elements - which are series-connected for generating delayed clock pulse signals w.r.t. input delay cycle circuit
Inventor: MIYAZAKI YUKIO
IPC: G06F1/10
Filed: 1991-12-23
Abstract: The clock pulse generator has a delay clock pulse generating circuit with numerous delay elements (211-215), generating delayed clock pulse signals (DC1-5) sequentially and serially delayed w.r.t. a basic clock pulse signal (C1) at the input (2) of the delay clock pulse generating circuit. A memory with several elements (201-205) stores a preset logic level in response to a transition in allocated basic, or delayed, clock pulse signal after application of an async. trigger signal (TR), w.r.t. the basic clock pulse signal. A clock pulse selection logic circuit (221) controlled by the memory output signal, acts on the time-proximal clock pulse signal transition. USE/ADVANTAGE - For rapid synchronisation, without use of higher frequency basic clock pulse signal.
