Title: Preformed roof lining for automobile - has protective edge strips esp. longitudinally to prevent damage during handling
Inventor: ROTH ERWIN DR ING
IPC: B60R13/02
Filed: 1980-12-17
Abstract: A preformed internal lining for an automobile roof comprises a rigid polymer foam shell. The edges of this shell, at least the longitudinal edges, are equipped with reinforcement rendering them insensitive to mechanical forces and thus protecting them from damage. The reinforcement may have a U-section, L-section or T-section. Alternatively the reinforcement may be a strip or band fitted along the edge. Pref. material for the reinforcement is impact-resistant thermoplastics, or crosslinked plastics, opt. contg. organic and/or inorganic reinforcing fibres. The reinforcement of the edges is designed to protect them from mechanical damage during handling, transport and installation. In a variant the reinforcement may be formed by fusing the foam along the edge of the shell so that the protective strip is an integral part of the shell.

Title: Novel frequency conversion method
Inventor: BESSLING GEB PRETTEREBNER
IPC: H03D7/16
Filed: 1981-03-04
Abstract: To achieve high frequency stability and, at the same time, the possibility of being able to use filters with wide tolerances, for example SSB filters, CW filters or the like, a highly stable frequency (crystal generator) is mixed with a frequency which has less stability but is easily variable, and fed into the filter. A second mixing with the second variable frequency produces the original highly stable frequency as the mixing product. The variable frequency can be frequency modulated, for example, during the first mixing process or processed into a single-sideband modulation. The final frequency always remains as stable as the original frequency of the first oscillator even with a frequency drift of the variable frequency, for example due to a variation with temperature.

Title: Device for detecting the running properties of railway waggons
Inventor: GOLMS REINHARD ING GRAD
IPC: B61L17/02
Filed: 1981-06-22
Abstract: In order to determine the running properties of train sections which are being shunted, the kinetic energy of the sections is determined at two successive measurement points on the track. A computer forms a running resistance value for the respective section from these values and from a known route-oriented coefficient which states the energy loss, caused by the sum of track resistances, of a section on its path between the two measurement points, which running resistance value contains the sum of all the resistances which act on the section. The running resistance values which are found can be converted to other travel speeds of the sections than those which were present when the measurement path between the measurement points was passed through. <IMAGE>

Title: Pressure reducer for air-guide ducts in air-conditioning installations
Inventor: FINKELSTEIN WOLFGANG
IPC: F24F13/14
Filed: 1981-07-21
Abstract: The invention relates to a pressure reducer for air-guide ducts in air-conditioning installations with a throttle flap which is mounted pivotably in a housing, a volume control in particular being connected downstream of the pressure reducer. In order that the pressure reducer generates an approximately constant differential pressure even in the case of variable volume flows, the surface of the throttle flap (2) is smaller than the associated flow cross-section in the housing (1) and a weight (G), which is adjustable in its relative position to the throttle flap (2), is arranged on the throttle flap (2). As a result of the varying effect of the flow forces on the surface sections of the throttle flap (2) situated on both sides of the pivot axis (3) on the one hand and as a result of the weight (G) on the other hand, return moments are created which result in the generation of an approximately constant differential pressure even in the case of variable flows. Moreover, flapping and vibrating movements of the throttle flap (2) are prevented. <IMAGE>

Patent DE-3135487-A1 (DE)
Title: Power engine based on ammonia and water as operating materials
Inventor: ENGELSBERGER MATTHIAS
IPC: F03G7/00
Filed: 1981-09-08
Abstract: A power engine in the form of a turbine or piston engine is operated by the pressure difference generated in the absorption of ammonia gas in water. Heat energy is fed to the resulting ammonia/water mixture, and water and ammonia are thus separated again. The ammonia is again fed to the power engine, whereas the heated water releases a part of its heat energy to mixture newly coming from the power engine. It is then discharged, and fresh water of preferably low temperature is fed in, in order to bind as much ammonia as possible. The power engine is especially suitable for the utilisation of low-temperature heat, for example for solar installations and for the conversion of waste heat of low-temperature type into mechanical or electrical energy.

Title: Play-free safety release coupling
Inventor: DASSER MANFRED DIPL ING
IPC: F16D7/08
Filed: 1981-09-23
Abstract: Safety release coupling with a hub which is arranged on a shaft and on which are arranged two coupling halves (2, 3), one (3) of which is connected in torsionally rigid fashion to the hub (1) and is spring-loaded in the direction of the other coupling half, which can rotate relative to the hub. Torque is transmitted between the coupling halves by balls (14) arranged between them which rest in ball recesses and, in the event of an overload, cross into different, larger ball recesses. To achieve the freedom from play in the circumferential direction, one coupling half (3) is connected via spring discs (22) to the hub (2), in particular by bolting the discs alternately to the hub and to the coupling half. By virtue of the fact that the discs are prestressed radially inwards, they snap into an end position opposed to the starting position after only slight axial loading. <IMAGE>

Title: Process for producing nickel, highly pure magnesium oxide and cement
Inventor: WYNN NICHOLAS PATRICK
IPC: C01G45/00
Filed: 1981-10-10
Abstract: By leaching with sulphuric acid, nickel is recovered from a nickel-containing oxidic raw material which also contains magnesium and iron, highly pure magnesium oxide and cement being produced at the same time. The heavy metals are separated off by an organic metal extractant, nickel, cobalt and manganese are stripped out of the latter by mineral acid and the nickel is recovered by a known process. Copper, zinc and iron are obtained by further stripping with sulphuric acid. The solution containing sulphuric acid is passed to cement manufacture. Magnesium carbonate and/or hydroxide-carbonate is precipitated from the aqueous solution, obtained when the heavy metals are separated off, with addition of carbon dioxide and ammonia, and an ammonium sulphate solution is formed. The precipitation product is separated off and calcined to give magnesium oxide. Gypsum, which is fired to give cement clinker, is formed from the ammonium sulphate solution. The sulphur dioxide-containing gas thus formed is processed in a sulphuric acid plant and used in raw-material leaching.

Title: Process for the preparation of a phosphonic acid mixture
Inventor: F DR SCHEUER GERHARD
IPC: C07F9/38
Filed: 1981-10-27
Abstract: An almost equimolar mixture of 1-carboxy-2-alkanephosphonic acids and 1-hydroxy-1,1,3-alkanetriphosphonic acids can easily be prepared by reacting 2-alkenoic acids, such as, for example, propenoic acid, methylpropenoic acid, 2-butenoic acid, 2-methyl-2-butenoic acid, 2-pentenoic acid and phenylpropenoic acid at temperatures of between 60 and 140 DEG C, followed by hydrolysis of the reaction product. It is advantageous to use the starting materials in a molar ratio of alkenoic acid to phosphorous acid to phosphorus trichloride of 2:3:1. Instead of the alkenoic acids, it is also possible to react chlorides or anhydrides thereof, in which case the amount of phosphorus trichloride required is reduced and that of phosphorous acid accordingly increased.

Title: Device for cleaning the inside of a pipe
Inventor: HIESTAND KARL
IPC: B08B9/047
Filed: 1981-12-24
Abstract: In a device (1) for cleaning a pipe (2), the cleaning tool (5) which can be actuated by a motor is constructed in the form of a saw blade, a tappet or the like, which can be driven in a translatory fashion, and an axially adjustable actuation piston (12) inserted in a cylinder (11) and acted on on both sides by pressure medium serves as drive motor to drive the cleaning tool (5), said drive motor being in drive connection with the cleaning tool (5) via a lifting shaft (13) and its translatory adjustment movements being reversible by means of a control valve (21) which is inserted in the pressure medium feed line (31), is constructed in a special manner, and is automatically switched over as a function of the position of the adjustment piston (12). The obstacle to be removed can thus be processed in an impacting or sawing fashion since the translatory movements of the lifting shaft (13) can have a rotational movement superimposed on them. And since the saw blade (5) extends only over a part of the circumference of the pipe (2), a large part of the passage cross-section remains free so that the device (1) can also be moved forward around bends in the pipe and a pipe does not need to be taken out of service for its inside to be cleaned because the rinsing water and waste water flows away virtually unimpeded. <IMAGE>

Title: Process and device for weft supply on looms
Inventor: SCHEFFEL BERND DIPL ING
IPC: D03D47/34
Filed: 1982-01-25
Abstract: The essence of the process is that the length of thread (1) to be inserted is stored in the form of several loops. Each loop consists of two partial loops (1.1, 1.2, 1.3 etc.). A partial loop is a piece of thread clamped between two points. These partial loops are formed in succession. For dispensing, one partial loop is released after another. For storage, the thread clamp (7) at the insertion member side is closed and the clamp on the bobbin side is open. The thread deflection elements (2.1, 2.2, etc.) take the thread (1) to the loop holders (8.1, 8.2, etc.) located respectively on the opposite side. For dispensing, the loop holders (8.1, 8.2, etc.) release the thread in sequence. Such a device can also be formed for the alternate supply of a plurality of threads. For this there will then be a multiplicity of thread clamps and movable eyelets (44, 44') allow thread insertion and removal. <IMAGE>
