Patent DE-3423220-A1 (DE)
Title: Side feeder for castings
Inventor: SCHOKOLOWSKI WERNER ING GRAD
IPC: B22C9/08
Filed: 1984-06-21
Abstract: The side feeder described comprises a feeder part and a feeder foot which has the form of an essentially horizontal connecting duct between the outlet orifice of the feeder part and the casting-side feeder neck. According to the invention, the feeder foot is provided with an insulating and/or exothermic jacket. As a result, the feeder foot can be given a very thin and narrow shape, for example in that its diameter, based on the circular cross section, is smaller by a factor of 0.1 - 0.7 than the diameter, based on the circular cross section, of the outlet orifice of the feeder part. Compared to a full-size feeder foot of the same efficiency this results in a substantial reduction in the fettling effort required for separating the feeder from the casting, as well as in the cost of the return scrap metal. Moreover, in the case of side feeders it is now also possible, for the first time, to fit the feeder neck with a knock-off feeder core which has the known shape of a disc provided with a central hole and which forms a predetermined breaking point so that the feeder can be knocked off readily. Possible materials for said knock-off feeder cores include the traditional materials for knock-off feeder cores, but preference is given to refractory heat-insulating materials such as silicon dioxide, aluminium oxide, magnesium oxide, titanium dioxide, aluminium silicate and other silicates and mixtures thereof.

Title: Induction heating device
Inventor: KLAERNER RENATE
IPC: H05B6/02
Filed: 1984-10-09
Abstract: The invention relates to an induction heating device for heating metallic workpieces which are conveyed successively on a roller bed or sliding guide as they pass through one or more inductors through which current flows. The unobstructed internal cross-section of the inductors is matched to the external contour of the workpieces. The inductors are arranged such that they can be replaced and are connected via contacts to the power source. The characteristic feature of the invention is that the group of inductors which is arranged in the path of the conveyor track for workpieces is mounted on a rotating table. A further group of inductors is mounted in a preparation position on the [lacuna] which is a mirror image of the vertical plane passing through the axis of rotation. The rotating table can be lifted out of the operating position by means of a rotating-lifting device and can be rotated through 180 DEG  in the lifted position and then lowered again, as a result of which the group of inductors located in the preparation position is lowered into the operating position. <IMAGE>

So that loads originating from directing moments are low and the directing forces resulting from the directing moments are at a great distance, one segment has at least three roller cages (13, 13', 13'' 13'''), each receiving at least one pair of supporting rollers (18), but at most two pairs of supporting rollers (18, 18'), the roller cages (13, 13', 13'', 13''') being mounted on the segment (4, 4', 4'') in a floating manner and, as seen in the billet extraction direction (22), at least one roller cage (13) being provided in front of the first driving roller (10, 23), at least one roller cage (13', 13'') being provided between the first and the second driving roller (10, 23) and at least one roller cage (13''') being provided behind the second driving roller (10, 23). <IMAGE>
Patent DE-3442372-A1 (DE)
Title: Multi-channel sound control system
Inventor: BERGER DIETER
IPC: H04H60/04
Filed: 1984-11-20
Abstract: Through the use of channel processors and a central computer, a sound control system can be controlled according to the invention based on the >>distributed intelligence<< principle, conventional manual operation, in particular also in the event of a data-processing failure, as well as a partially or fully automatic adjustment of the sound control system being enabled according to requirements. In this way, in particular in systems of a substantial size, the sound recordist is relieved of physical adjustment work so that he can concentrate to an even greater extent than before on the artistic work. Furthermore, expensive mechanical components such as adjusters for the microphone amplifiers are not required and the relevant components (microphone amplifiers) of each sound channel can be accommodated in a place which is no longer necessarily below the mixing desk surface. Greater freedom for the design of the mixing desk is thus provided.
Patent DE-3502135-A1 (DE)
Title: Circuit arrangement of a switching amplifier
Inventor: NESTLER JOHANNES DR ING
IPC: H03F3/217
Filed: 1985-01-19
Abstract: The circuit arrangement of a switching amplifier in which the output voltage is generated by the addition of part-voltages, a corresponding number of voltage stages, which can be bypassed by diodes, being connected in series via switches depending on the magnitude of the AF input signal to be amplified, which is sampled with a sampling frequency which is in the RF range, and in which a low-pass filter is provided for eliminating the radio-frequency components which are caused by the switching steps of the switches, has the object of effectively filtering harmonics whilst, at the same time, controlling shortcircuit currents by means of power semiconductor switches. This is achieved by the fact that each switch (21, 22, ... 2n) constructed in the form of a power semiconductor is followed by a choke coil (41, 42, ... 4n) which is in each case inserted into the output line (terminals A, B) after the junction of a power semiconductor, used as a switch, for a voltage source (11, 12, ... 1n) with the diode (31, 32, ... 3n) bypassing this voltage source, and that the total inductance of all choke coils is selected in such a manner that, together with the capacitance of a capacitor (5) in parallel with the output line, results in a low-pass filter for the radio-frequency components. <IMAGE>

Title: Single-bar connection, in particular for the longitudinal chords of lattice-like segments for tunnel support frames
Inventor: SEIZ RUDOLF
IPC: E21D11/28
Filed: 1985-04-18
Abstract: The invention relates to a single-bar connection, in particular for longitudinal chords of lattice-like segments for tunnel support frames, which has a coupling section provided with a claw and an end section onto which the chord end can be welded, the surface of the claw being provided with recesses and projections which can be brought into positive-locking engagement with corresponding projections and recesses of the claw of the bar to be connected, and the projections and recesses of each claw having a helical tooth system which lies in a plane which is inclined relative to the longitudinal axis of the coupling sections or longitudinal chords. To avoid any cross-sectional weakening of the coupling sections and to increase the bearing cross-section while simultaneously reducing the overall diameter of the single-bar connection, it is proposed that the claws in engagement with one another by their helical tooth system be provided with a thread on their outer surface, onto which thread at least one nut can be screwed for the mutual fastening of the claws.

Patent DE-3528955-A1 (DE)
Title: Arrangement for angular measurement, in particular for geodetic instruments
Inventor: FEIST WIELAND DR
IPC: G01C1/06
Filed: 1985-08-13
Abstract: The invention relates to an arrangement for angular measurements, having a rotating divided circle and optoelectronic scanning systems. It can be applied in all geodetic and precision-measuring instruments for measuring horizontal and vertical angles. It is the aim of the invention to carry out angular measurement with high accuracy, reliability of measurement and a low outlay on measuring means for all classes of accuracy and with the exclusion of errors of division. The object of the invention consists, in the case of coarse and fine measurement ranges, in eliminating the influence of the errors in circular division and reading errors at the same time as the angular measurement, without complete rotations of the divided circle. This object is achieved when at least one absolutely coded division is provided concentrically with the measurement division for the rotating divided circle, the scale divisions of the divided circle form at the one reading point the index for the divisions of the other reading point or vice versa, and the size of the angle between fixed and rotatable scanning systems is determined by reading the coded division and from interpolation measurement, and the measurement division and coded division are read simultaneously by the scanning systems.

Title: Method and arrangement for determining the wall thickness of cylindrical hollow bodies
Inventor: MUELLER BERND DIPL ING
IPC: G01B17/02
Filed: 1985-09-07
Abstract: The invention relates to a method and an arrangement for determining the wall thickness of cylindrical hollow bodies, especially for checking the dimension and for determining the corrosive erosion of the inner surface of pipelines, for example of pipes carrying fresh steam over a long period in power stations, using suitable elastic waves. This is achieved in that, according to the invention, elastic waves which revolve in a circular manner and are in a frequency range having a wavelength corresponding to the order of magnitude of the external radius of the hollow body are excited in the cylindrical hollow body, and the maximum gains of the excited waves and the associated frequencies and ordinal numbers of the resonance are determined, from which the radius ratio  alpha  = (Ri)/R of the hollow body is determined, and the wall thickness d = (1- alpha )(D)/2 is calculated, with the aid of the calculated dispersion relationships (in this case: R1 = internal radius, R = external radius, D = diameter). For implementation, according to the invention, an assembly which consists of a transmitter and receiver is arranged in the measurement range of interest in the hollow body, the transmitter being connected to a tunable generator and to a frequency meter, and the receiver to a visual display unit.
