Title: Method and apparatus for removing mould cores made of glass, ceramic, moulding sand or the like from castings
Inventor: BELSCHNER ALWIN
IPC: B22D29/00
Filed: 1993-04-07
Abstract: The invention proposes a method and an apparatus for removing mould cores (23) made of glass, ceramic, moulding sand or the like from castings. In this method, the mould core (23) is granulated by the action of ultrasound by means of at least one transmission element (21 - sonotrode). In an apparatus suitable for carrying out the method, an ultrasound generator (18) is in operative connection with the transmission element or elements (21), a working region (22) of the transmission element, which region can be moved into the mould core (23) to granulate the latter having essentially the same cross-section as the mould core (23). By means of this method, significantly higher working speeds and lower noise development can be achieved, the space requirement for the ultrasound device likewise being considerably smaller than that of conventional apparatuses. <IMAGE>

Title: Non-ferrous metal recycling in phosphating baths - comprises leaching the slurries with phosphoric acid and recycling the non-ferrous metal solns. obtd. in the phosphating bath for iron surface treatment
Inventor: KAEHLER JOERG DR ING
IPC: C22B3/06
Filed: 1993-05-14
Abstract: A process for non-ferrous (NF)-metal recycling in phosphate baths comprises leaching the NF-metal contg. slurries or suspensions with dil. phosphoric acid at pH 1.2-1.8 and 60-100 deg.C (or 30-120 mins., thus transforming esp. Zn, Ni and Mn completely into recyclable phosphoric acid solns., while NF-metal free iron phosphate remains as a useful residue. USE/ADVANTAGE - The process selectively separates NF metals (esp. Zn, Ni and Mn) which can be directly recycled to the phosphating bath used to treat surfaces of iron sheets to give them a protecting coating. Thus the losses of 50% Zn, 10% Ni and 10% Mn usually associated with the phosphating process are avoided. The iron phosphate residue is also useful. Simple leaching step is inserted between phosphating bath and solid/liquid sepn. The amt. of reagent used is low, no foreign reagents are used and there is thus no contamination of the bath. There is no waste water. The NF metal free iron phosphate residues are used as precursors for the prodn. of phosphorus fertilisers.
Patent DE-4316481-A1 (DE)
Inventor: HOLDERBAUM THOMAS DR
IPC: C11D3/39
Filed: 1993-05-17
Abstract: A granulated product contains an inorganic peroxide compound, a granulated activator and an excipient. The granulated activator is prepared by agglomerating (a) finely ground activator material with (b) water- or alkali-soluble polymers, the ratio a : b being greater than 90 : 10. Before being mixed with the inorganic peroxide compound and the excipient, the granulated activator is sprayed with an organic compound melting between 30 and 100  DEG C from the group of non-ionic surfactants, long-chain alcohols, polyethylene glycols, fatty acids, waxes and their mixtures. The finished product is thus prevented from dissociating during transport or motions. After spraying, the granulated activator preferably contains 1 to 25 % by weight, in particular 2 to 10 % by weight, of the organic compound melting between 30 and 100  DEG C.

Title: Display device for balancing machines
Inventor: LENART COLOMAN DR
IPC: G01D7/02
Filed: 1993-06-17
Abstract: The invention relates to a display device for balancing machines, which displays the imbalance angular position or the compensating angular position and the imbalance magnitude or the magnitude of the compensating masses in an analogue representation. In this arrangement, the measured values are represented as an illuminated diagram on a monitor. To display the angular position, a diagram is provided in which an annular surface (5, 13) is visible on which, with the aid of a visible mark (1, 16), the respective angular position of the imbalance and also the direction of rotation (7, 12) and the current angular position (7, 12) of the rotor can be displayed. Provided within the annular diagram (5, 13) is a bar diagram (4, 14), whose displayed or marked length represents a measure of the imbalance magnitude or the compensating mass. In addition, within the bar diagram (4, 14), a tolerance range (9, 15) can be marked in accordance with which it is immediately recognisable whether, on the basis of the displayed imbalance magnitude, imbalance compensation must be carried out. <IMAGE>

Title: Arrangement for controlling the optical transparency (light transmission) of a window
Inventor: GIRLICH HEINZ DIPL ING
IPC: B64C1/14
Filed: 1993-08-26
Abstract: An arrangement for controlling the optical transparency of a window, in particular in an aircraft, has a transparent material whose optical transparency can be varied by means of an additional material. In order to vary the optical transparency, the window or the like is provided with an area-covering layer made from conventional liquid crystal elements. The optical transparency of the layer is varied by means of an applied AC voltage. The invention consists in that the arrangement has a control unit 1 as well as a light sensor 4 and a controller 5, and that a stepless (continuous) variation of the optical transparency of the liquid crystal surface 3 is produced when at constant frequency the AC voltage can be regulated between zero and a maximum value, and together with the liquid crystal surface 3 and the light sensor 4 the control unit 1 forms a control loop in such a way that the brightness measured by means of the light sensor 4 is compared with the brightness input at the controller 5, and the liquid crystal surface 3 is then driven in such a way that the measured brightness corresponds to the input brightness. It is particularly advantageous in this case that the liquid crystal layer has a simple design, and the brightness arising within a space as a consequence of insolation can be limited to a prescribed value. <IMAGE>

Title: Apparatus for releasing, cutting to length and supplying the thread end on spinning cops
Inventor: BUEHREN HEINZ
IPC: B65H67/08
Filed: 1993-11-04
Abstract: Apparatus for releasing, cutting to length and supplying the thread end on spinning cops. The object is to develop an apparatus of this type further, in such a way that the success of cop preparation is improved even where cops which are difficult to prepare are concerned. This object is achieved in that, in the case of cops transported at predetermined intervals, means act continuously on the cops in a transport stage extending over a plurality of cop centre intervals, in order to release the thread, the cops being exposed to a continuous rotary drive. According to the invention, the cops are to execute a timed movement during rotation, and, over the said transport stage, the rotary drive is to be set in such a way that, simultaneously with the rotational movement, an advancing movement is also transmitted to the cops. The cops are to maintain the interval between them and, on the said transport stage, are not to touch partitioning means arranged between them. <IMAGE>

Title: FET with weak inversion circuit
Inventor: LOTH HARTMUT DIPL ING
IPC: G05F1/569
Filed: 1994-05-17
Abstract: A FET (1) is connected to a weak inversion circuit (3,33) forming a protective or diagnostic circuit. A stabilising voltage (5) for the circuit is maintained by a control voltage (4). The control voltage also supplies the gate (2) of the FET. When the protective circuit monitoring the FET detects an overload, the voltage is altered.

Abstract: A trunked communications network utilizes a distributed control switch (multisite switch) to provide digitized audio and control signals from various audio sources to one or more audio destinations connected through the switch. Signals from audio sources are preassigned and routed onto an audio channel (i.e., a time slot) on a time division multiplexed (TDM) audio bus through a corresponding interface module at a switch "node". A separate serial "message" bus is provided for informing each interface module of initial bus slot assignments, broadcasting call unit and group destination IDs, identifying active channels (TDM bus slots) and other network control information. A dedicated Network Interface Module (NIM) is provided in the multisite switch to permit the interconnection and communication between multiple multisite switch controlled networks. The network interface module allows a remote multisite switch controlled network to appear as just another node to the local multisite switch. <IMAGE>
