Title: Detector circuit for checking coin metal - has instrumentation bridge generating output to phase discriminator identifying false metal
Inventor: SCHLICHTING GERHARD
IPC: G07D5/08
Filed: 1980-09-11
Abstract: A detector circuit is used to check and identify the metallic characteristics of coins against counterfeit versions. The coin (M) is allowed to interact with a resistance (2) within an a.c. instrumentation bridge circuit (1). The bridge is supplied with an a.c. signal that has a frequency that relates to the characteristics of the true coin metal. A half bridge (6,7,9) provides a reference for the system. The voltage outputs of the measuring bridge (U3,U4) are squared by operational amplifiers (14,15,16) to provide inputs to flip flops (17,18) to generate a phase discrimination function. A test circuit (12) generates an output indicating acceptance or rejection.

Title: Heat exchanger heat flow determination method - uses temp. of liq. flow currents before and after heat exchanger
Inventor: HABY GEORG ING GRAD
IPC: G01K17/08
Filed: 1980-10-04
Abstract: The method determines the heat flow (N) in a heat exchanger, resulting from the delivery or extraction of heat by a transfer medium having a specific heat (Cw). Before delivering the medium into the exchanger, its temp. (Tk) is measured and a partial current (Fk) is tapped off from it. From this current and one (F) leaving the heat exchanger a mixed current (Fm) is produced, of the same quantity as the constant partial one (Fk) and containing the partial one (F) completely. The temp. (tm) of the mixed current is measured and the heat flow (N) determined from the formula N=Cw.Fk(Tm-Tk).

Patent DE-3044222-A1 (DE)
Title: Plaster board panel - with rounded or chamfered abutting edges eliminates cracks
IPC: E04F13/04
Filed: 1980-11-25
Abstract: Plaster slabs or plaster boards often suffer from cracks along the abutting joints because of lack of flexibility. It is suggested therefore to round off or chamfer the abutting edges of the slabs or boards in such a way that the broad wedge-shaped configuration results in enough deformability of the jointing material to eliminate cracks. Similar problems arise when plaster is applied subsequently to plaster board panels. This can be remedied by adding parallel taper notches to the smooth surface of the panels.
Patent DE-3103605-A1 (DE)
Title: Knocking detector for an internal combustion engine with spark ignition
Inventor: TOSHIO ENOSHIMA
IPC: H03H7/46
Filed: 1981-02-03
Abstract: Knocking detector which perceives the oscillations of a motor in order to produce an oscillation signal which represents these oscillations. The signal is rectified and smoothed by an averaging circuit to produce a smoothed ground noise comparison signal. The signal from the sensor is compared with the ground noise comparison signal in a comparator either before rectification or after rectification, which comparator produces a knocking signal, which represents the occurrence and the strength of the knocking, whenever the signal from the sensor is greater than the ground noise comparison signal. A first disconnection circuit responds to every ignition in that it interrupts the feed line of the oscillation signal to the comparator for a fixed time interval directly after each ignition in order to prevent the ignition noise influencing the perception of the knocking. A second disconnection circuit responds to the knocking signal from the comparator in that it disconnects the feed line of the rectified signal at least to the averaging circuit in order to prevent the knocking influencing the comparison signal. An exemplary embodiment of a knocking detector of this kind is illustrated in Fig. 2. <IMAGE>

Abstract: The motor plinth (1) designed approximately in a plane-parallel form has on its upper side a non-rotatable receiving ring (3) (Figure 1) which grips around the power take-off shaft (2), arranged vertically and driven by the motor, and which serves for receiving and holding a stirring arm (17) or an attachment device (33), for example a chopping unit (Figure 2). In order to bring about a firm seat of the stirring arm (17) fitted with a plinth (15) (Figure 1), a clamping ring (4) is provided which grips rotatably around the receiving ring (3), has an actuating arm (5), and whose flange part (6) fitted with cutouts (9, 10, 11) presses the noses (12, 13, 14) of the stirring arm (17) firmly against the receiving ring (3) in the locking position. For holding an attachment device (33), the plinth (15a) of the attachment device (Figure 2) is fitted with slots (62, 63, 64), into which bolts (18, 19, 20) enter when the clamping ring (4) rotates, which bolts are attached to the receiving ring (3), the actuating arm (5) of the clamping ring (4) additionally being fitted with an internal slide (38) which, on the one hand interacts with a blocking rod (39), which is mounted displaceably in the motor plinth (1) and is moved by the motor switch, and which, on the other hand, interacts with a locking bolt (31) which is part of the attachment device (33), and whose head part (35) enters a slot (37) in the slide (38) (in the locking position). The locking bolt (31) is additionally provided with an opening (45) into which (in the locking position) a locking finger (44) protrudes, which is part of the lid (34) of the attachment device (33). In order to be able to pivot the stirring arm (17) relative to the motor plinth (1) into a rest position (direction of arrow Z), the plinth (15) is connected to the stirring arm (17) via a joint or hinge (24, 24a), the fingers (16, 16a) arranged firmly on the stirring arm (17) additionally being released with their noses (13, 14) by the clamping ring (4) with the flange part (6) during pivoting in the opening direction, whereas the nose (12) of the plinth (15) remains firmly retained between the shoulder (53) and the flange part (6) or the ring (52). <IMAGE>

Title: Device for converting an analog input voltage into a digital output variable
Inventor: KNICK ULRICH DIPL ING
IPC: H03M1/00
Filed: 1981-06-26
Abstract: In this device, an analog/digital converter (4) is provided which exhibits a reference voltage connection (3) and two input voltage connections (1, 2) and, between each of the input voltage connections (1, 2) and the reference voltage connection (3), a periodically operable switching device for automatic zero calibration. To prevent the input voltage source from being loaded by the switching device, one input (+,-) of a feedback-type high-gain differential amplifier (5) is connected to one input voltage connection (1, 2) of the analog/digital converter (4) and the other input (-, +) of the differential amplifier (5) is connected to the reference voltage connection (3) of the analog/digital converter (4) and the output voltage (U) of the differential amplifier (5) is connected between the reference voltage connection (3) of the analog/digital converter (4) and the other input voltage connection (2, 1) of the analog/digital converter (4). <IMAGE>

Title: Retaining means for fixing a heating pipe of a floor-heating system
Inventor: NICKEL WOLFGANG ING GRAD
IPC: F16B15/00
Filed: 1981-06-27
Abstract: A retaining means (H) for fixing heating pipes (R) on heat-insulating panels (P) has flexible barbs (6, 7). These barbs rest on rigid stops (8, 9) in the retaining position. Pushing the retaining means (H) into the panel (P) results in a relatively small hole in an anchoring layer (22), through which hole the barbs (6, 7) slip, the barbs being bent in the direction of the shaft (1, 2), with the result that they are approximately parallel to said shaft, an enlargement of the hole by the barbs (6, 7) thus being avoided. After the barbs (6, 7) have slipped through the hole in the anchoring layer (22), the retaining means (H) is drawn back again somewhat, the barbs (6, 7) spreading apart and, thereafter, having a large resting surface for resting on the anchoring layer (22). Owing to the retaining means being drawn back, the heating pipe (R) can move upwards, as a result of which there is formed an interspace (23) into which screed composition (E) can flow. <IMAGE>

Title: Device for ultrasonic scanning using an ultrasonic multicell array
Inventor: HASSLER DIETER DIPL ING
IPC: G01S7/52
Filed: 1981-08-04
Abstract: The invention relates to a device for ultrasonic scanning using an ultrasonic multirow array (2). The latter comprises a multiplicity of transducer elements arranged in rows and columns. Said elements are driven in groups by selector switches. In this arrangement, the driven group is clocked on in stepwise fashion to step the beam in the row direction, and the clocked group is also switched onto different transmitting and/or receiving surfaces. A base equalising amplifier (22) and, e.g. a field equalising amplifier (24) as well suppress switching noise, which can be produced in the case of beam stepping in the row direction. The aim of the invention is to specify a solution which can be integrated particularly easily into already existing systems. This aim is achieved by the combination of the following features: only a first number of rows covers per signal-processing channel (MS), a base equalising amplifier and, e.g. also a field equalising amplifier. The remaining number of rows contains per signal processing channel (RS) only one switching interference suppressor, which consists of a frequency filter (29) and a switching element (27). The output signals of said suppressor are added onto the first number of rows before being relayed to the equalising amplifiers. The invention is used in ultrasonic imaging devices in medical ultrasonic diagnostics. <IMAGE>

Title: Process and device for fitting panels, forming a facing covering, on walls
Inventor: EBERLE HANSDIETER
IPC: E04F13/08
Filed: 1981-08-14
Abstract: The invention relates to a process and a device for fitting panels (1), forming a facing covering, on walls (2) using flexible spacers. Dowels, the number and arrangement of which corresponds to the form and dimension of the panels (1) forming the facing covering, are first of all set into the walls (2). With the interposition of flexible spacer elements (4, 3), connecting plates (6) are screwed, by means of in each case one screw (5) engaging into one of the dowels which has been set, onto the wall (2) on which the panels (1) are fastened. By means of the screws (5), the connecting plates (6) are adjusted such that their surfaces directed away from the wall (2) lie in a vertical plane. Unevennesses and deviations of the wall (2) from the desired position consequently do not affect the facing covering. The purpose of facing coverings, besides that of cladding walls, of improving the sound and heat insulation of said walls can be improved considerably by an insulating-material filling (18) between wall (2) and facing covering. <IMAGE>

Title: Spare-wheel recess for vehicles
Inventor: FABIAN FRANK-DIETRICH DIPL ING
IPC: B62D43/10
Filed: 1981-09-01
Abstract: In a motor vehicle, a spare-wheel recess is arranged, for example, in the floor of a boot in order to accommodate a space-saving spare wheel. So that it is also possible for a defective normal wheel to be accommodated in the spare-wheel recess, which contributes to the overall length of a motor vehicle, the clear width of the spare-wheel recess, seen in the vehicle longitudinal direction, is smaller by the extent of a reduction in diameter, brought about by a clamping device on just two opposite sides of the tyre tread surface of a defective normal wheel, than the diameter of a normal wheel under operational pressure, and the clear width of the spare-wheel recess, seen transversely to the vehicle longitudinal axis, is larger by the extent required to accommodate the tyre mass displaced by the reduction in diameter, than the diameter of the normal wheel under operational pressure.
Patent DE-3143188-A1 (DE)
Title: A control method and control system for model vehicles
IPC: A63H19/24
Filed: 1981-10-30
Abstract: A control method and control system for model vehicles, for example model railways run on track systems, enable the simultaneous and reciprocally independent control of a plurality of model vehicles. For this purpose, a binary data stream comprising a multiplicity of data words is transmitted via the rail to individual receivers in the model vehicles, where the data stream serves simultaneously as the operating current for the drive motors and the model vehicle receivers. Each data word transmitted very frequently in succession in a time unit has a channel allocated individually to each model vehicle which comprises two bits only, one of which indicates forward movement and the other backward movement. Each receiver has a bit counter (1) which counts all the bits of each received data word. At the outputs of this counter, the individual bits are available separately in each case for the different channels so that they can be transmitted to a two-bit cycle memory via a combination logic (4) which can be adjusted individually in each case for the respective model vehicle. With the aid of a data checking device (6), each data word is checked at its end for correctness and, if it is identified as correct, the information temporarily stored in the two-bit cycle memory (2) is forwarded to a two-bit transfer memory which then stores this information until a new received data word has been identified as correct. The correctness of each data word is therefore checked immediately upon receipt and the information allocated individually to each receiver is forwarded to control the drive motor only if correctness has been identified. Since the addressing of the individual receivers is carried out solely by counting the bits of each data word, no special address component is required in the data word, since each bit of the data word is used to represent a control command and also to indicate the respective address. <IMAGE>

Title: Sound-absorbing body, in particular for installation in silencers
Inventor: GAISBAUER THOMAS ING GRAD
IPC: F01N1/24
Filed: 1981-11-06
Abstract: To form a sound-absorbing body (1), in particular for installation in silencers, a main part (2) of a compressible sound-absorbing material, for instance in the form of a mineral-fibre tube shell, is compressed radially and introduced into a sheet (3), for example of glass fabric, which has an undersize with respect to the unloaded circumference of the main part (2). As a result, the surface (2c) of the main part (2) bears with an adjustable high contact pressure against the inner side of the sheet (3), so that on the one hand the sheet (3) is secured against relative movements in high-velocity air flows and in the event of sudden pressure surges, and on the other hand the otherwise generally relatively soft region (2b) close to the surface of the main part (2) is compacted and improved in its mechanical integrity. In the absence of any adhesive and with unproblematical suitable material selection, a non-combustible body (1) can be produced which is resistant up to high temperatures of several hundred degrees celsius. <IMAGE>

Title: Flow-adapted dialyser cover
Inventor: SIGDELL JAN ERIK DR
IPC: B01D61/30
Filed: 1981-11-10
Abstract: Dialysers for artificial kidneys using hollow fibre bundles have terminal connections for the blood flow or drainage of blood designed as covers on both ends of the cylindrical housing for the hollow fibre. These covers usually have a central nozzle for the blood hose and form a distribution space for distribution of the blood entering there to the ends of the hollow fibre in the bundle and correspondingly at the outflow end. Previous embodiments of such covers were unsuitable in respect of flow because they caused not only large variations in the flow velocity of blood inside the distribution space but also led to detachment of the flow from the axial cover wall. The present invention provides a calculation method for cover designs which does not have such deficiencies as a result of which novel cover contours with improved properties are achieved. For this purpose, the flow fields of 1) the rotationally symmetrical hold-up flow and 2) a spread circular sink flow are combined with each other after which the large number of flow lines is selected by the rim of the sink area as the cover contour. Such a flow line defining the contour cross-section is determined for calculation.

Title: Rotary duplicator
IPC: B41L11/08
Filed: 1982-04-23
Abstract: The invention relates to a rotary duplicator which is essentially characterised in that the printing forme carrier, carrying the printing forme, is not constructed, as has previously generally been customary in rotary printing machines, by a solid cylinder which absorbs the pressures and transmits them to its own axle, but merely has one function of carrying the printing forme and is held only between a drive roller and a back pressure roller, the drive roller driving the printing forme carrier and the back pressure roller by frictional engagement. As a result, a considerable reduction in the loads driven and a less expensive design are achieved. <IMAGE>
