Title: Telephone exchange circuit reconnecting calls at subscriber's request - provides caller facility for cancelling call at any time before final connection without charge
Inventor: FREYMADL GEORG DIPL ING
IPC: H04M15/12
Filed: 1980-07-17
Abstract: The automatic electronic telephone exchange provides facilities for reconnecting incoming calls to a different number at the subscribers request. Such a request is stored in a memory and acted on automatically if a call to the original number is not answered within a specified time. The reconnection amounts to setting up a second call and is charged as such. As the number selected by the subscriber requiring the rerouting may involve a trunk connection the extra charges can be considerable. The caller is informed of the situation. When a call is reconnected the charging for the original connection is suppressed until the new number is found and has answered. The charge meter is then started at the correct rate for the call involved. Before the reconnection is commenced the caller is informed of the situation by an audible signal and also advised of the charge rate which will be in force. He then has the option of terminating the call at any instant up to the time the called number answers, without any charge.

Title: Image processing target acquisition and tracking - uses Bayes classifier to classify target and terrain and controls measurement data acquisition
Inventor: LAIER WALTER DIPL ING
IPC: G01S3/786
Filed: 1980-09-09
Abstract: An arrangement for detecting and tracking a target contains a sensor which responds to electromagnetic radiation. It automatically optimises the distinction between the target and the terrain and is very simple. The measurement values produced by the sensor are reduced to two intensity levels for the target and the terrain. The target and terrain are classified in a classifier using Bayes Theorem. The classifier controls the acquisition of measurement data via a switching function. The classifier a posteriori signal is fed to a coordinate analyser which determines the target coordinates using a maximum target point probability method. A delay element forms a signal which acts on the a priori signal from the posteriori signal. The target coordinates are fitted with time and a difference signal between the predicted and measured maxima fed to the delay element.

Title: Arrangement for setting the cycle time of folding knives
Inventor: BOETTCHER ROLF DIPL ING
IPC: B65H45/18
Filed: 1981-05-22
Abstract: The invention relates to an arrangement for setting the cycle time of intermittently operating folding knives on paper sheet-processing machines. The aim of the invention is, with minimum time consumption, to achieve in a selective manner an exact adjustment of the cycle time for folding knives to the sheet format to be processed with a respective sheet gap necessary for the folding accuracy. For this purpose the transmission ratio between the drive of the folding knives has to be controlled such that any belt paths on the conveying means of the folding machine have exactly allocated to them in each case one complete operating cycle of the folding knife. This object is achieved according to the invention in that a device capable of varying the speed, preferably a gear with infinitely variable transmission ratio, is connected to a measurement and control arrangement which exactly and automatically sets the associated cycle time for any belt path input into a preselection counter unit. <IMAGE>

Title: Comminuting device for fibrous material from mineral substances
Inventor: ZIPPE ALFRED
IPC: D01G11/00
Filed: 1981-06-13
Abstract: The invention relates to a comminuting device for fibrous material, preferably waste material from mineral substances, for example glass wool. So that such waste material can be melted again, it is necessary for it to be comminuted to the extent required, and hitherto this has had to be carried out manually because of a lack of suitable devices. According to the invention, the material coarsely comminuted, for example by means of a conventional cutting unit (11), is picked up by a plurality of hammer-like elements (28) rotating about a common axis and is moved by these in the direction of numerous mutually spaced bars (34) which are arranged parallel to the axis of rotation of the hammer-like elements (28). The rotating hammer-like elements (28) and the fixed bars (34) form interacting breaking and shearing elements, between which the fibrous waste material is sufficiently comminuted to ensure that it can be fed to the melt again in metered quantities. The device is mainly employed for comminuting waste glass fibres or glass-fibre products, in order to recover this material by recycling and thus save energy and raw materials. <IMAGE>

Title: Polarographic measurement apparatus
Inventor: MAAS MICHAEL ING GRAD
IPC: G01N27/48
Filed: 1981-07-08
Abstract: A polarographic measurement apparatus has a receptacle (1) having a measuring electrode (7) and a counterelectrode (8) to be placed in an electrolyte (11), and a test voltage can be applied between said electrodes. The object of the invention is to disclose a method enabling the effect of nonlinearities and instabilities on the measurement to be eliminated at minimum technical cost in such polarographic measurement apparatuses. According to the invention, this object is achieved by controlling the test voltage (U = U0 + DELTA U) by means of a network (5) as a function of the receptacle measurement at the test electrode (7), in such a way that the effective voltage difference between the test electrode and the electrolyte (10) directly surrounding it remains constant. <IMAGE>

Title: Strutting for roadway support frames
Inventor: PODJADTKE RUDI ING GRAD
IPC: E21D11/28
Filed: 1981-07-17
Abstract: In the known strutting as defined in the preamble for channel-like roadway support frames, U-bolts are used which in each case overlap both section lugs of a support frame. Special clamping pieces serve to secure the U-bolts to the support frame. The spacers are then secured with the U-bolts to the support frame with the aid of straps, the straps enclosing the bases of the support frames and their adjoining webs. The many individual parts are disadvantageous on the known strutting. Furthermore, the U-bolts can only be attached in exceptional cases to support frames already set. Use in the mechanical support system in full-section driving is not possible. In contrast, the strutting (8) according to the invention consists only of a spacer (11, 11'), the ends (20, 20') of which are adapted in a positive-locking manner to the contour of the lug fillets (6) and the lug ribs (7) defining the lug fillets (6), and of hook bolts (9) which largely conform to the surfaces (13) of the section lugs (5) of the support frames (1). Such strutting (8) therefore has only a few individual parts. Consequently, it can be used not only in a simple manner but also in a variable manner. In addition, the securing of the strutting (8) to in each case only one section lug (5) of the support frames (1) ensures that the hook bolts (9) can also be readily attached to support frames (1) already set. The strutting (8) can therefore be used advantageously in the mechanical roadway support system in full-section driving without assembly difficulties.   <IMAGE>

Title: Seat mount, in particular for a child's push-chair with a wheel frame which can be folded up transversely to the direction of travel
Inventor: GLAESER DIETER
IPC: B62B7/06
Filed: 1981-07-30
Abstract: The invention relates to a seat mount for releasable attachment to a wheel frame of a child's push-chair, aligned either in the direction of travel or in the opposite direction, in particular for a child's push-chair with a wheel frame which can be folded up transversely to the direction of travel. The seat mount has two side parts which are connected to one another at one end region by a backrest frame and at the other end region by a foot rest. Both the backrest frame and the foot rest are designed as lever mechanisms which can be folded up transversely to the direction of travel. A seat is connected to the side parts of the seat mount such that it can be pivoted about imaginary axes essentially extending in the direction of travel, and in the region of its longitudinal centre has a folding region which divides the seat into two halves and permits the seat to fold. In order to ensure that the folding up is reliable, in the seat mount according to the invention there is attached to a part of the seat mount which during folding up moves upwards relative to the side parts, an actuating element which engages underneath the seat in its folding region and forces the seat to fold up.

Title: Cable pulley for driving automotive cableway vehicles
Inventor: PACH KARL ING
IPC: B60B19/00
Filed: 1981-08-07
Abstract: Automotive vehicles for suspended cableways are already known. The frictional grip which can be achieved with this is, however, too low to be able reliably to overcome relatively large carrying cable gradients with a relatively high vehicle weight. The object of the invention is therefore to provide a cable pulley for driving automotive cableway vehicles which has a simple design and ensures reliable locomotion of the vehicle on the carrying cable even in the case of large carrying cable gradients. The cable pulley according to the invention consists of two parts (1, 2) which are connected to one another, as a result of which two grooves (13, 14) are produced on the circumference, one groove to roll on the supporting cable and the other to roll on the coupling part. The part (1) is connected to a flange (4) which is arranged on the drive shaft (5) and the part (2) is arranged on the round shape (6), exhibited in this area, of the drive shaft. By means of springs (8, 9) which are arranged on the connecting element (10), the two parts (1, 2) have axial freedom of movement. Since the diameters of the grooves (13, 14) are somewhat smaller than the diameters of the carrying cable or of the coupling parts a good clamping force is produced. <IMAGE>
