Title: Stacking and transporting pallet and pick-up device for the latter
Inventor: DUENNWALD NORBERT DIPL ING
IPC: B65D19/38
Filed: 1981-03-24
Abstract: The significance of pallets as efficient aids when transporting and storing goods is well known. However, the search always continues for further means of rationalisation, including better utilisation of space both empty and laden, lowering the empty weight and simple handling in conjunction with the required apparatus. A new system, consisting of stacking and transporting pallets with a matching pick-up apparatus, as described in the application P 2927124, can be used efficiently instead of more complex pallets. However, it has been shown that this novel system can be simplified further, the suitability for the function also being improved. The aim of this part of the invention is to design the picking-up and setting-down operation of empty and laden pallets on flat ground and in a pile to be so secure that any occasional slipping-away or pushing-forwards, in particular when the load is being picked up by the stacking apparatus, is avoided. The essential improvements according to the invention consist of frictionally acting structural elements in the pallet and pick-up apparatus. <IMAGE>

Title: Apparatus for conveying air via filters on a textile machine
Inventor: FELLER GERD
IPC: D01H11/00
Filed: 1981-05-29
Abstract: The invention relates to an apparatus for conveying air via filters on a textile machine, having at least one air channel with a filter. In this apparatus, there is arranged in the region of the filter (10; 11) a flow sensor (8; 12) which determines the air speed and which is connected to a measuring instrument. This flow sensor can be arranged in the air channel in front of or behind a filter or can be located in front of or behind a fan located in the air channel. In a housing having two inlet orifices, one outlet orifice and a fan, there can be used two flow sensors which can be adjusted individually and which are electrically connected in series or in parallel. In general, a number of flow sensors corresponding to the number of filters to be monitored are arranged in the air channels or in collecting channels combining the flow of a plurality of air channels, in such a way that the air throughput quantities of all the filters can be determined directly or indirectly by the addition or subtraction of air throughput quantities in the air channels or collecting channels. The flow sensor provides the possibility of a simple monitoring of the necessity for the cleaning of the respective filter. <IMAGE>

Title: Method for determining the instantaneous power of a driving motor
Inventor: REISCH JOHANN DIPL ING
IPC: G01L3/24
Filed: 1981-10-14
Abstract: As an addition to the method described in the main patent for determining the instantaneous power of a driving motor, a further method step is proposed which allows the influence of the temperature of fluid in the hydraulic coupling (3) on the accuracy of the power determination to be taken into account. According to the main patent, the power to be determined is passed via a hydraulic coupling (3), from the input speed (n1) and output speed (n2) of which the slip (s) of the hydraulic coupling (3) is calculated, this, together with the measured input speed (n1) being sufficient for the determination of the torque (M) from a memory (13) containing the characteristics of the hydraulic coupling (3). According to the invention, the calculated slip is subjected to a correction if the temperature of the fluid of the hydraulic coupling (3) deviates from a predetermined temperature. At temperatures above the predetermined temperature, the calculated value of the slip (s) is increased and, at temperatures below this temperature, is reduced. For this purpose, a detector (18) which detects the temperature of the fluid in the hydraulic coupling (3) is provided, containing as the active element for the determination of the fluid temperature a resistor through which there flows current fed in at constant voltage. The resulting current, which is thus temperature-dependent, is used in the arithmetic unit (10) to correct the calculated slip. The desired power is finally obtained by calculation from the torque (M) and the input speed (n1).   <IMAGE>

Title: Cap, in particular for a fuel tank
Inventor: REUTTER HEINRICH
IPC: B60K15/04
Filed: 1981-11-26
Abstract: In order to place a cap, in particular a fuel filler cap, on the filler pipe with a low actuating force, in a manner which is gentle on the seal and nevertheless provides reliable sealing, it is equipped with a rotary-linear clamping device (20) which has the effect of pressing the sealing ring (4) against the mouth of the filler pipe when the rotation stop has struck the counter stop of the filler pipe. Via the rotary-linear clamping device (20), a pressing member (3) on which the sealing ring rests is pressed with such force against the pipe that finally a torque-limiting locking device (19), onward movement brings about idle, actuating the rotary-linear clamping device (20), of the rotatable actuating member. A predetermined axial pressure exerted on the sealing ring (4) to press it against the filler pipe (5) corresponds to the maximum torque transmissible by the torque-limiting locking device (19). An impermissible overpressure or vacuum can be prevented with the aid of an overpressure or vacuum relief valve. The cap can be constructed as a lockable cap or cap without a lock. <IMAGE>

Patent DE-3150457-A1 (DE)
Title: Hot rolling mill
Inventor: FIGGE DIETER DIPL ING
IPC: B21B1/18
Filed: 1981-12-19
Abstract: Rolling mills for the hot rolling of bar stock and wire, which are equipped for the intermediate and finishing train with three-high roll stands, staggered two-high roll stands or double two-high roll stands or in which the finishing train comprises two-high roll stands in horizontal-vertical arrangement in the form of individual stands or a finishing block, are difficult to adapt to different rolling programmes. In order decisively to facilitate this adaptation, the roll stands provided for the intermediate and finishing train each allow a selectable number of up to four rolling passes taking place continuously one after the other and, in the case of groove wear, the replacement of only the grooves affected. Such double-disc three-high roll stands (5, 10) are equipped with three rolling shafts, each of which bears a disc roll at both ends. Driving is performed from below, transversely to the direction of rolling, allowing a single driving motor (3) to be used for the entire rolling train if a plurality of stands are arranged in series. Within the roll stand (5, 10), the upper and the lower rolling shaft are each provided with a separate adjustment device and a suitable common drive. The disc rolls can be replaced individually. <IMAGE>

Title: Cold-curing polyurethane-based binder for moulding sand
Inventor: NOLTE CHRISTIAN DIPL CHEM DR R
IPC: C08G18/67
Filed: 1981-12-24
Abstract: The invention relates to a cold-curing polyurethane-based binder for moulding sand mixtures for the production of casting cores and moulds. It is formed by reacting a solution of a monomeric polycyclic phenol containing one OH group per ring with a polyisocyanate containing at least two NCO groups per molecule, the molar ratio between the OH groups and the NCO groups being in the range from 1 : 1.0 to 1.5. The novel feature here is that the solvent for the phenol is a mixture of a carboxylic acid ester, an acid amide containing tertiary amide groups and a ketone, each of these constituents having a boiling point of above 130 DEG C, and that one or more acetylenically unsaturated compounds of the formula <IMAGE> where R<1> and R<2> are hydrogen atoms or hydrocarbon radicals having up to 8 carbon atoms or form a 5- to 8-membered cycloaliphatic radical, in each case with inclusion of the carbon atom which is adjacent to both of them, are added to the solvent. Casting cores and moulds produced using the novel binder have superior initial strengths in addition to good decomposition properties.
Patent DE-3202709-A1 (DE)
Title: Process and apparatus for coating a substrate with inhomogeneous layers
Inventor: EICHINGER PETER DR
IPC: G02C11/02
Filed: 1982-01-28
Abstract: The invention relates to a process and to an apparatus for coating a substrate with inhomogeneous layers. The invention is intended to provide a simple and economical solution to this problem. For this purpose, the substrate (15) is first exposed in a plasma reactor (1) to the atmosphere of a base gas, for example silane SiH4. In a plasma discharge, this base gas is decomposed and deposits on the substrate. This base gas is mixed with one or more further gases such as, for example, nitrogen and ammonia which, by reaction with the gas components of the base gas, deposit on the substrate as amorphous, non-stoichiometric compounds. By varying the proportions of base gas and admixed gases, the coating deposited on the substrate is thus provided with physical properties which are variable across the thickness of the coating. The process is particularly suitable for surface blooming of optical elements such as lenses or the like over a wavelength range which is wide as compared with the conventional interference layers and can also be used in the infrared region and, in addition, for decorative staining of metal objects or plastic objects, for example spectacle frames. By means of such inhomogeneous blooming, the refractive index of the coating can be continuously reduced, for example from about 4 to about 1.5 and less. <IMAGE>

Abstract: Propeller which is accelerated solely by centrifugal force and without combustion due to the system. Used for this is a hollow cylinder (Fig. 1) which is rotatable about its axis and is opened at one of the two circular surfaces for the inflow of medium. The curved wall (3) of the cylinder is designed to be sufficiently thick for there to be space for a multiplicity of radial, elongated channels (4) in it. During the rotation of the cylinder, the medium (e.g. air or water) is moved through the channels by centrifugal force and is collected by a rectifying apparatus (Fig. 2) which encases the cylinder. It is deflected in the rectifying apparatus in such a way that it produces a repulsion at the nozzle (12). The main ranges of application are in aircraft and watercraft, it being possible for any engine to be used. <IMAGE>
