Title: Bus, or bus element with an understructure made up of interlaced cross members
Inventor: BINDER HELLMUTH DIPL ING
IPC: B62D47/02
Filed: 1981-03-27
Abstract: The invention relates to a bus (1) or bus element (2) with an understructure made up of interlaced cross members (7) whose longitudinal bearing members, formed essentially from an upper member and a lower member (11, 12) are bent at right angles vertically out of the straight course in the region of an axle (5) of the vehicle in order to provide a free space for spring compression movements of the axle (5) of the vehicle. In order to obtain a high longitudinal rigidity of the frame accompanied by a low outlay of material, the lower member (12) of the longitudinal bearing members is bent downwards at right angles and extends below the axle (5) of the vehicle. The upper member (11) can then be of linear construction, as a result of which it becomes particularly rigid. The lower member (12) can contain a releasably inserted section (14) in order to make axle mounting easier. The frame structure is particularly suitable for articulated buses, in particular for so-called rectilinear sliding pair buses with a high longitudinal thrust loading of the understructure made up of interlaced cross members in the region of the central axle of the bus. <IMAGE>

Title: Method of a hybrid system for recovering environmental heat for heating installations
Inventor: HOELTER HEINZ ING GRAD
IPC: F24D3/18
Filed: 1981-05-15
Abstract: In the recovery of environmental heat by flat heat exchangers, such as for example are mounted on roofs, the flat heat exchangers have to be made very big in order to provide sufficient heat in unfavourable weather conditions. In favourable weather conditions, such flat heat exchangers provide more heat than necessary and place excessive demand on the heat pump. According to the invention, the flat heat exchangers are made so small that, in particular in unfavourable weather conditions, they provide only a part of the required heat quantity and in addition air/water heat exchangers are used, which provide the differential quantity. In favourable weather conditions, the heat quantity provided by the flat heat exchangers can suffice and the air/water heat exchangers can remain out of operation.

Title: Electrodynamic impact device for a print mechanism in typewriters or similar office machines
Inventor: SCHWEIZER HORST ING GRAD
IPC: B41J9/38
Filed: 1981-12-01
Abstract: Electrodynamic impact devices for printing mechanisms of typewriters or similar office machines should consist of simple components which on the one hand permit the use of assembly machines and on the other hand can be used for high impact frequencies with a long service life. Although printing hammers (1) which execute a linear movement and have at one end a magnetisable hammer head (18) and at the other end an exciter coil (17) have proven suitable for this, they require good guidance. This is achieved according to the invention in that the printing hammer (1) is mounted displaceably on the one hand with its hammer head (18) in a bearing block (20) near to the print position and on the other hand with guides (61, 62, 63, 64) which are arranged inside the exciter coil (17) on the free ends of guide webs (32, 34). The printing hammer (1) has short, low-friction guides. <IMAGE>

Title: Process and equipment for biological effluent treatment
Inventor: REIMANN HANS DR RER NAT
IPC: C02F3/04
Filed: 1981-12-22
Abstract: The invention relates to a process for biological effluent treatment, having a two-stage treatment procedure with feeding of an oxygen-containing gas, in which the effluent is passed in one stage (1) through a trickling body (2) or filter and in the other stage (10) through an activation tank (11). To obtain high treatment values, provision is made for feeding a treatment gas containing more per cent by volume of oxygen than air to one stage (1) via an inlet line (5), passing the resulting off-gas via a gas flow path (6) from one stage (1) into the other stage (10) and at the same time adjusting the rate of the treatment gas fed in such a way that the total off-gas, taken off via an off-gas line (17) after passing through the two stages (1, 10), still contains 15 to 70% by volume, preferably still 25 to 50% by volume, of oxygen. In the case shown, the first stage (1) is designed as trickling body and the second stage (10) is designed as an activation tank with a final clarification tank. To obtain good nitrification values, however, a converse design of the two stages is also possible. <IMAGE>

Title: Printing unit for a typewriter or similar office machine having a receiving device for a change cassette with a type wheel
Inventor: GERKEN HEINER ING GRAD
IPC: B41J25/24
Filed: 1982-02-27
Abstract: In printing units with type wheels in typewriters or similar machines, an easy exchangeability of the type wheel must be guaranteed. For this, it should be possible to remove the type wheel from the mounting or insert it therein as easily as possible, without the person operating the machine requiring particular dexterity. For this purpose, a change cassette which has a type wheel mounted freely in it and which can be inserted into a receiving device of the machine is known. This type wheel has a sprung driving pin which engages automatically into a recess of a wheel receptacle in the machine during a locating run. The sprung pin makes the disposable type wheel considerably more expensive. The object on which the invention is based is to simplify the change cassette. According to the invention, the sprung driving pin (82) is arranged eccentrically on the wheel receptacle (79). The type wheel (31) can thereby be designed in a substantially simpler way, since the driving pin (82) is a constructional part of the wheel receptacle (79). The material outlay for the type wheels (31) is reduced considerably, the coupling of the type wheel (31) to the wheel receptacle (79) taking place automatically after a locating run. <IMAGE>

Title: Mixing head for an oil gasification burner
Inventor: HOFFMANN GERD
IPC: F23D11/40
Filed: 1982-03-27
Abstract: The mixing head of a so-called "blue burner" has an external combustion tube and, arranged concentrically therein, a gasification tube. The upstream end of the combustion tube is closed off by a screen, through the central opening of which the fuel is injected, which is mixed with combustion gases circulating rotationally outside around the gasification tube. In the combustion tube, between the gasification tube and the downstream open end of the combustion tube, there is arranged a guide device, in particular in the form of a tube of square cross-section, so that recirculation ducts for combustion gas are formed between the guide device and the combustion tube. As a result of this, the noise development of the "blue burner" in operation is reduced and the sooting in the combustion tube close to the screen is avoided.

Patent DE-3233390-A1 (DE)
Title: Combustion engine, device for this and related units
Inventor: EICKMANN KARL
IPC: F02B75/02
Filed: 1982-09-09
Abstract: The invention is concerned particularly with measures to raise the pressure and the temperature in the external combustion compartment of a combustion chamber fed by a compressor set between compressors and expanders to such a level and at the same time to keep the entire engine or combustion system operating reliably that at the high temperature even solid fuel, for example in rod form, can be burnt with a specific rate of advance of the fuel rod. The temperature can be raised to such a level that the advancing fuel rod self-ignites and burns. Over-hot gas following combustion may be efficiently cooled by water injection and used for performing work. In implementing the invention it emerged that as a result of good compressors, valves and the design of the combustion chamber, such engines with external combustion compartments can also function as petrol engines with levels of efficiency which are equal to those of existing petrol engines. Fuel powder can also be burnt and the parts which serve for perfecting the engine may have further applications in hydraulics and pneumatics and in aircraft construction and vertical take-off of fixed-wing aircraft. Since the expanders in such engines perform work for any downstroke, the engines are especially compact or they give increased performance for their weight and dimensions.

Title: Process for the preparation of low-substituted, readily water-soluble carboxyalkyl-polysaccharide (mixed) ethers and corresponding polysaccharide mixed ethers
Inventor: RAEHSE WILFRIED DR
IPC: C08B31/12
Filed: 1982-10-15
Abstract: A process for the preparation of low-substituted carboxyalkylpolysaccharide (mixed) ethers with improved solubility in water is described. The process is characterised, in particular, by the excess of alkali in the alkalisation stage being suited to the degree of etherification of the process products which is subsquently required. The solubility in water of the low-substituted process products can be further influenced by fixing the initial temperature on addition of the etherifying agent. The invention finally relates to correspondingly low-substituted water-soluble carboxyalkylpolysaccharide mixed ethers which, besides the carboxyalkyl ether residues, contain corresponding residues of other etherifying agents. The polysaccharide (mixed) ethers according to the invention contain, in particular, about 0.25 to 0.75 mol of carboxyalkyl residues besides 0.001 to 0.6 mol of other ether residues, in each case per mol of anhydroglucose unit.
