Title: Analogue/digital converter
Inventor: WOHLSTREICHER FRANZ
IPC: H03M1/00
Filed: 1987-10-15
Abstract: The invention relates to an analogue/digital converter having a signal input for an analogue input signal, having a signal output exhibiting n bits for a digital output signal and having a number of comparators to which the input signal and reference voltages are applied. To reduce the number of comparators to the number of bits of the signal output, the converter is constructed with a digital feedback of such a form that each comparator or bit is associated with one reference voltage source which supplies a basic reference voltage, the basic reference voltages in each case increasing by a factor of two from bit to bit starting from the bit having the lowest significance. Furthermore, means are provided which increase the reference voltages of all subsequent bits having a lower significance by the basic reference voltage associated with one comparator when the input voltage at this comparator is equal to or greater than the reference voltage applied to it.

Title: Process for producing a composite part and also a composite part
IPC: B32B5/18
Filed: 1987-12-09
Abstract: The invention relates to a process for producing a composite part and also to a composite part, in particular a sound-dampening part. A backing part of plastic is bonded to a foam-based dampening part. In order to achieve improved acoustic properties with a production process which is as simple as possible, a sound-insulating part in the form of a heavy-gauge film is arranged between the backing part and the dampening part. Before a bonding of the parts, the backing part and the sound-insulating part are heated to an approximately soft and spongy state and the backing part, the insulating part and the dampening part are then bonded to one another by pressing. The backing part (2), the dampening part (4) and the insulating part (3) are bonded to one another by placing directly against one another. <IMAGE>

Title: Sound-insulating strips for the assembly of lightweight walls
Inventor: MANTEL JUVAL DR ING
IPC: E04B2/82
Filed: 1988-01-21
Abstract: In the assembly of lightweight walls, in particular at the joints with solid walls, leakages occur, caused by the unstraight line followed by the solid wall. In practice, the sealing of these locations is problematical. The use of self-expanding insulating strips, usually foams fully impregnated with bitumen or similar materials, is suitable, the limits of the system becoming much more considerable if there are large joints (expanding to twice or more of the original thickness). The present invention is intended to offer adequate air-borne sound insulation even in the case of self-expanding insulating strips which expand to three to five times their original size. The invention is constituted by incorporating in the expanding strips islands of sand, which are either filled directly into cavities or are incorporated in the form of small sand bags.
Patent DE-3808519-A1 (DE)
Title: Method of processing the fluidised-bed ash obtained in the filters
Inventor: ACKERMANN MANFRED
IPC: C04B18/02
Filed: 1988-03-15
Abstract: Fluidised-bed ash which is obtained, in particular, in the combustion of washery tailings and is carried out together with the combustion gases and retained in the filter, can be fed to a useful utilisation if it is intensively mixed with a binder and then is combined and mixed with nuclei-forming coarser granular material which has previously been moistened through to saturation. The mixed product is then subsequently stored for curing and is then used as aggregate. Optimum matching to the demand is possible because the method provides that the coarser granules in the particle size range from 1 to 10 mm are fed in as nucleus-formers, with the particle size spread and the proportion of granules being targeted to the application of the aggregate to be produced in each case, by the addition of the nucleus-formers. Besides cement, lime or gypsum can also be used here as binder, with the added amount of lime and gypsum to be determined taking into account the active amount of lime present in the fluidised-bed ash or as a function of the highly dewatered anhydrite proportion present therein. The material of optimum particle size and nature of particles can then be used as light-weight aggregate for the widest range of fields of application. <IMAGE>

Title: Cathode filter for implantation in the right-hand cardiac ventricle for the treatment of leukaemia
Inventor: NEUMANN ANITA
IPC: A61F2/00
Filed: 1988-04-06
Abstract: The invention relates to a square filter which measures 3.5 or 4.5-5.5 cm, is negatively charged with the current intensity of approx. 10<-6> amperes, is intended for implantation into the endocardium of the right-hand cardiac ventricle by means of operation and serves the purpose of physical therapy of leukaemia. This filter is also termed a cathode filter, since it is negatively charged. The magnitude is governed by the magnitude (the diameter) of the right-hand cardiac ventricle. (Smaller in children than in adults). This negatively charged filter for use in leukaemia therapy is based on the virus theory of the cause of leukaemia. The basis is a virus theory developed by Dr. Hasumi, in accordance with which said viruses have lost electrons in the course of the evolution in the protein coat, and are thus partially positively charged. Consequently, in their chemical behaviour these viruses obey the laws of Coulomb attraction, in accordance with which they can be absorbed by a negatively charged filter. This filter must be exchanged after some time. The advances brought by the negatively charged filter in the case of leukaemia treatment are measured by continuous monitoring of the blood parameters. Note: the level of the negative charge would still have to be precisely determined in clinical research by appropriate in vitro or animal experiments under ECG monitoring.

Title: Data transmission gateway for a control unit exhibiting a processor
Inventor: SAUVAJOL RENE
IPC: G06F13/38
Filed: 1988-04-11
Abstract: The invention relates to a data transmission gateway for a control unit with processor, particularly in the context of a decentralised control system which is operated in real time such as, for example, a time-division multiplex switching system, this gateway connected to a system bus (SBUS) of the processor of the unit being intended for ensuring the exchange of information in the form of digital data with at least one data transmission connection of the system or with at least one peripheral device of the unit. The gateway exhibits a first automatic device (17) as interface to the system bus (SBUS), a second automatic device (19) as interface to the transmission connection or the peripheral device, a command memory (20) which controls the two automatic devices in dependence on the addressing supplied by an internal sequence circuit (21) of the gateway to the command memory, a processor block (22) which executes the arithmetic and logic operations to which the data exchanged via this gateway are to be subjected, and a main memory (23) which is used jointly by the processor block and the two automatic devices. The sequence circuit addresses the command memory in dependence on the microinstructions which are supplied by this command memory and/or the processor block, and in dependence on the information sent out by the two automatic devices. <IMAGE>
Patent DE-3824039-A1 (DE)
Inventor: GLEIM GUENTER
IPC: G11B7/09
Filed: 1988-07-15
Abstract: A method for compensating offset voltages selectively in a focusing circuit that focuses a beam from a source of light on a recording medium and in a tracking circuit that positions a beam of light on data storage tracks on a recording medium. A beam of light reflected from the recording medium is directed onto a photodetector which has a plurality of photodiodes. The difference of the output voltages from the photodiodes is taken for generating an error signal which is stored as a reference during a first stage in open or closed state of the circuit selected. The selected circuit is then closed and a compensation parameter is supplied in a second stage to controls in the selected circuit. The compensation parameter is then varied until the error signal is substantially equal to the stored reference. The compensation of the offset voltages is independent of the tracking circuit, and the offset voltages in the focusing circuit can be compensated when the tracking circuit is closed.

Title: Process for producing corrosion-inhibiting oxide layers
Inventor: WINKLER REINHART PROF DR RER N
IPC: C23C22/68
Filed: 1988-08-22
Abstract: The invention relates to a process for producing corrosion-inhibiting oxide layers on surfaces of structural elements consisting of steels or nickel-based alloys by hot-water oxidation of the structural elements for several hours in an aqueous medium, in particular for suppression of the radioactive contamination of the inside surfaces of primary circuits of water-cooled nuclear reactors. The object according to the invention is achieved in such a way that at least hydrated oxides, known per se, of metals of subgroup IV of the periodic table of the elements are released in the aqueous solution and the concentration of the metal compounds, which lead to the formation of these hydrated oxides, does not exceed the order of magnitude of 1  mu mol/l. It has been found that the hydrated oxides of extremely low solubility of some metals, above all of titanium and zirconium, in a particle size of less than 10 nm act as crystallisation nuclei during the formation of the protective layer. They are also capable of penetrating into pores, which may already be present, having diameters of from 10 to 100 nm. The protection becomes effective in a total quantity, specific to unit area, of foreign metals in the order of magnitude from 0.1 g/m<2>, i.e. at only about 1/100 of the quantity hitherto used.
Patent DE-3829713-A1 (DE)
Inventor: KOERNER JUERGEN DR ING
IPC: B65G47/86
Filed: 1988-09-01
Abstract: A device (1) serves to transfer articles, such as sweets, between a delivery wheel 2 and a jaws (4) of a take-up wheel (5) for packaging. The device (1), takes the form of levers (9, 10) mounted to a pair of coaxial shafts (7, 8). Blocks (11) with clamping faces (11.1, 11.2) are carried on the levers and hold the articles during transference. A mechanism drives the shafts (7, 8) so that the levers perform independent movements and change positions during one operative cycle, so that lever 10 moves upwards to clamp article 14 to face 11.1, and the device moves to deliver the article to a pair of jaws 4, lever 10 then retraces its path to take up the original upper position of lever 9, and lever 9 moves on to take up the original lower position of lever 10, ready to reverse roles. Wheel 2 therefore does not have to wait for a return movement of lever 10 to the lower position as originally. <IMAGE>

IPC: B60Q1/42
Filed: 1989-04-29
Abstract: A switching device emits signals for direction indication, switching over from dipped headlights to full beam, the headlight flasher and the horn of a motor vehicle. For triggering the signals, it has a manually actuatable switching lever (10, 12) which is mounted so as to be rotatable and tiltable in a switching console (14). A tension spring (26), one end of which engages directly or indirectly on the switching lever (10, 12) and the other end of which engages directly or indirectly on the switching console (14), extends in the switching lever axis (28). The tension spring (26) is hooked into a pin (34), which is connected to the switching lever (10, 12) and at the same time fulfils the function of a tilt axis, and of a rotary stop and ensures a minimum spacing between switching lever (10, 12) and switching console (14). The horn function is implemented by means of a push-rod (162) which is mounted in the switching lever (10, 12) and on which a switching piece (178) of a switching element is mounted. The flashing function is carried out by means of two microswitches (20, 24) mounted off-centre on the switching console (14), it being possible to actuate said microswitches by rotating the switching lever (10, 12) and overcoming catch positions. The switching over between dipped headlights and full beam occurs by tilting the switching lever (10, 12) between catch positions (61) of a switching link (18) in which the central microswitch (22) is actuated in all switching positions by means of a component (130) which engages through the switching console (14). The headlight flasher facility is triggered by contact pieces (182, 184) which are mounted at the lower end (148) of the switching lever (10, 12) or on the switching link (18) and can be brought into contact by tilting the switching lever (10, 12) into a key position defined by the switching link (18). <IMAGE>
