Title: Measuring circuit for electronic scales
IPC: G01D5/241
Filed: 1987-06-26
Abstract: In a measuring circuit, the capacitance (C0) of a measuring capacitor is changed by the load (P) and it has an oscillator circuit (Osz) which exhibits two operational amplifiers (OP1, OP2), the first operational amplifier (OP1) being connected as integrator and its output being connected to the input of the second operational amplifier and the second operational amplifier (OP2) is connected as Schmitt trigger and a correction capacitor (CP) is provided for correction of the nonlinearity caused by stray capacitances (CS). The signal formed by the frequency (f) at the output of the oscillator circuit (Osz) passes to a microcomputer (MC) which mathematically allocates a corrected frequency value (f<*>) to the frequency value (f), which frequency value corresponds to an improved linear variation (f<*>) of the dependence on the frequency on the load (P). The correction is effected taking into consideration a correction capacitor (CP) which is connected in parallel with the measuring capacitor (C0) and is adjustable for alignment. <IMAGE>

Title: Baking oven
Inventor: THUEMLER MANFRED DIPL ING
IPC: F24C15/02
Filed: 1988-04-16
Abstract: In known baking ovens, the baking sheet support is automatically extended when the door is opened. This automatic slide-in mechanism can be taken out of operation by means of a change-over lever. The baking oven door and the baking sheet support are mechanically connected to one another in such a way that it is not possible to remove the door from its hinges. In the new baking oven, the coupling is designed in such a way that the baking oven door and the slide-in part can be removed from the appliance. This makes cleaning of the baking oven muffle much easier. A hook (6), which is welded onto a rolling grid structure (2) overlaps a vertically movable bolt (7) which is arranged on the baking oven door (10) and has a slide (8). The slide (8) is mechanically connected to a threaded rod (14) of a pivotable lever (9) via a rod assembly (11) which includes a nut (13) of coarse pitch. Levers (9) can be used to uncouple the baking oven door (10) and the grid structure (2) in such a way that both parts (10, 2) can be removed from the appliance. The baking oven is suitable for use in free-standing domestic electric cookers or for fitted or built-in appliances. <IMAGE>

Title: Electronic lock device with an insertable key for operating closing devices and the like and for switching electrical devices on and off
Inventor: KHALILI MOHAMMADREZA KARBASDEH
IPC: G07C9/00
Filed: 1988-04-20
Abstract: An electronic lock device with an insertable key, both of which are first coded with a positive or negative voltage potential at their conducting contact points, contains at least one signal system, a plurality of pnp and, respectively, npn transistors with bias resistors and relays, in order, with a voltage source, to form a closed circuit for activating the relay and operating the interlock when the key (2) is correctly inserted in the lock (1) and both all positive and all negative contact points are correctly above one another and correspond to one another. The transistors, which are connected to one another in accordance with a logical AND operation, are divided group by group. As a result, the relay is activated when all transistors are switched. The contact points between key and lock can be determined in matrix notation which can consist of m rows and n columns. m = 10 and n = 9 thus provides more than 10<9> coding possibilities. <IMAGE>

Title: Method and apparatus for the ad hoc measurement of the biomass present and for the ad hoc assessment of the state of fermentation in bioreactors by measurement of the sedimentation properties of a sample with the aid of ultrasound
Inventor: GERMERDONK ROLF PROF DR ING
IPC: C12M1/34
Filed: 1988-06-09
Abstract: For indirect ad hoc determination of the dry matter in biofermenters and for direct assessment of the rheological properties of the bioparticles it is possible to measure the level of sedimentation, and the sedimentation process itself, in a measurement chamber filled with the biosuspension with the aid of an ultrasonic measurement technique. The method can be employed even for biosuspensions which are opaque and/or form agglomerates. Ad hoc recognition of unfavourable operating states such as excessive shear stress or formation of excessively large agglomerates is also possible. The dimensions of the measurement chamber should be at least five times those of the largest bioagglomerates, and those of the connector, which is as free of internal fittings as possible, between the measurement chamber and fermenter should be 1.5 times.

Title: Method and device for the germicidal treatment of aqueous or granular goods
Inventor: BOEHNENSIEKER FRANZ
IPC: A61L2/10
Filed: 1988-08-19
Abstract: For the germicidal treatment of aqueous or granular goods the latter are exposed to UV radiation during movement along a transport path. At the same time, the goods are acted upon during movement in such a way that essentially all the regions or particles of the goods are exposed to the UV radiation. A treatment device for goods having a pasty consistency can comprise UV radiation sources (1) arranged on one or both sides of the transport path formed by interacting transport rollers (2). The speed and direction of rotation of the transport rollers (2) can be adjusted independently of one another with the result that alternate surfaces of the goods are exposed to UV radiation and the layer thickness of the goods is simultaneously reduced in the transport direction. In the case of granular goods, the transport path can be designed as a transport belt along which there are turning devices which ensure that the goods are turned during UV irradiation. <IMAGE>

Title: Shunting device for mining trucks
Inventor: GOERG HERBERT
IPC: B61J3/04
Filed: 1988-08-23
Abstract: The invention relates to a shunting device for mining trucks in which drivers of the shunting device can be guided to move the said shunting device against projections of the mining trucks. In order to be able to shunt specific shunting distances within narrow tolerances but on the other hand also to facilitate the coupling of drivers of the shunting device to trucks, the drivers are constructed as separate coupling vehicles 7 which are guided in a guide 1 by means of rollers 6 and are equipped with two jaws 18 which can be pivoted with respect to one another. In their initial position, the jaws 18 are pivoted apart from one another in opposite directions and can be moved under one of the towing crossmembers 20 connected to the mining trucks. In order to drive the truck, the jaws 18 are pivoted towards one another in such a way that they form an upwardly open, essentially rectangular groove which engages securely or with only a low degree of play around the towing crossmember 20 which is fixed to the truck so that shunting distances can be set exactly. In order to release the shunted mining truck, the jaws 18 are pivoted out of their driving position in opposite directions out of the level area of the towing crossmember 20 so that the said towing crossmember 20 and thus the mining truck are released and the coupling vehicle can be moved back into its initial position. <IMAGE>

Title: Folding wall, in particular sliding-folding door for shower partitions and the like
Inventor: ENGELBERTS LOTHAR
IPC: E05D1/02
Filed: 1988-09-16
Abstract: The invention relates to a folding wall, in particular a sliding-folding door for shower partitions and other dividing walls, with two wall elements (11, 12), one (11) of which consists of a pivoting wing and the other (12) of which consists of a folding wing connected to the pivoting wing in folding joints (13) and preferably guided on head and foot rails (9, 10). According to the invention, a profiled strip (19) which is equipped with joining strips (20), arranged pivotably on it, for the two wall elements (11, 12) is arranged between the two wall elements (11, 12). The profiled strip preferably consists of a plastics strip, to which the joining strips (20) can be connected via hinge webs (sealing webs) or the like. The profiled strip (19) expediently has lateral profile recesses (22) which can receive the joining strips (20) in the closed state of the sliding-folding door. With the aid of the profiled strip (19), a perfect joint bridging of the two relatively pivotable wall elements (11, 12) can be achieved, with reliable sealing-off of the sealing gaps. <IMAGE>

Title: Hose storage drum, in particular for underwater oil-transfer systems
Inventor: FASSE CONRAD
IPC: F16L3/01
Filed: 1988-10-01
Abstract: The hose storage drums serve, in underwater oil-transfer systems, for winding up hoses of an inner diameter of 20-50 cm for sea depths up to 400 m. In storing the hoses on drums with a horizontal axis, problems arise as a result of varying sagging of the individual coils in the lower region. In the case of winding up in horizontal planes onto a drum with a vertical axis, there is the risk of sliding off outwards of superposed hose coils and there is a very great tilting moment as a result of the fact that the drum becomes very high in the case of relatively long hoses. In hose storage drums (3) with a vertical drum axis (2) for the spiral-shaped winding onto drums of hoses (5) with great nominal widths, the mutual loading of the coils of the hose (5) which has been wound onto the drum can be avoided and problem-free winding onto and unwinding from the drum can be made possible by the hose storage drum (3) having a casing (6) in the form of a truncated cone with a step (7) running around in a spiral manner as a support for the coils of the hose (5). A hose deflection (8) with a support (10) with a number of rollers (12) arranged along a curved path, which support can be displaced on a guide column (9) by means of a drive (11), is controlled in such a manner that the hose intake (13) constantly coincides with the height of the coil of the hose (5) running off from or onto the hose storage drum (3). <IMAGE>
