Title: Acceleration and angle-of-inclination sensor
Inventor: KAPPNER HELMUT DIPL ING
IPC: G01P15/08
Filed: 1981-01-31
Abstract: An acceleration and angle-of-inclination sensor with selectable proportionality between input and electrically analysable output variable. The sensor according to the invention is used for measuring horizontal acceleration and measuring angle of inclination, particularly in vehicles. It offers a solution for the transition from the mechanical/physical quantities of acceleration or inclination to an electrical reference variable which can then be applied to visual or acoustic indicators. As an intermediate measurement quantity, the distance of a guided mass is evaluated which is travelled by the latter under the influence of the abovementioned physical quantities. An excellent means of the sensor is the simple mechanical structure which allows low-cost applications and mass production.

Patent DE-3121546-A1 (DE)
Title: Electronic circuit for stepping motors
Inventor: MERKLE PAUL
IPC: H02P8/20
Filed: 1981-05-29
Abstract: The special drive circuit illustrated for rotation stepping motors having three stators and three rotor pole rims is constructed according to the invention such that the corresponding stepping motor cannot only be driven in both rotation directions, to the extent that a new drive starts on the stator immediately after a pause in running has been completed, whose rotor poles are located just in the starting position. Before a stepping motor which is driven in such a manner is brought into use, the rotor must also be rotated by hand or using some form of assistance into its null position (zero position), unless it is already located in this null position in this case, since it is necessary to reset the flipflops before the motor is brought into use each time, by briefly applying H potential to the line, after which the output A is at H potential. <IMAGE>

Patent DE-3137833-A1 (DE)
Title: Device for monitoring the coal flow through a line
Inventor: LAPLANTE DONALD W
IPC: C21B5/00
Filed: 1981-09-23
Abstract: Device for monitoring the coal flow through a line (16 in Fig. 1) from a coal bunker (12) to a feeder (18). A detector (32) sensitive to radiation determines the amount of coal present in a line section (16) and produces an impulse sequence which is scanned to determine whether the line section (16) is empty, partly filled or completely filled. If the line section (16) is partly filled, a partial-flow alarm is produced. If the line section (16) is empty, an empty alarm is produced and the feeder (18) is stopped after a predetermined quantity of coal has been deposited on the feeder (18). If the line section (16) is partly filled and a shut-off valve (14) between the coal bunker (12) and the line (16) is closed, a coal-accumulation alarm is produced. If the line section (16) is filled and the coal profile on the feeder (18) does not correspond to the full profile, a coal-blockade alarm is produced. If the line section (16) is partly filled and the coal profile on the feeder (18) corresponds to the full profile, a ventilation alarm is produced. A self-test switching circuit periodically simulates each of these states for checking the device. <IMAGE>

Title: Edging block for fixing artificial lawns
Inventor: REUTER FABIAN
IPC: E01C13/00
Filed: 1981-11-03
Abstract: The invention relates to an edging block for fixing artificial lawns or similar ground coverings in playing fields. It is the object of the invention to fix the artificial lawn or similar ground coverings of playing fields securely on all sides and make it possible at any time for this fixing to be released without difficulty. This object is achieved by the use of a frame in conjunction with a clamping strip. The artificial lawn is thereby fixed securely on the edging block and can be released at any time, for example for repair purposes. It is absolutely essential that the loosely layed artificial lawn be clamped down due to its large shrinkability, due to the size of the surface area and being subjected to different temperatures. Figure 2 shows a sectional illustration of an edging block with a metal frame and clamping rail, and also the fixed artificial lawn. From the drawing, it can be seen that the edging block (1) is provided with a metal frame (14) which resembles a U-section, on which the clamping strip (6) together with the rubber-elastic support (13) is fixed. The elasticity of the rubber section (13) reduces the risk of injury. The U-section shape of the metal frame profile (14) permits seamless connection of adjacent synthetic coverings (11), such as, for example, a running track. Sufficient frictional connection is ensured by the clamping strip (6) being fixed at three points to the edging block (1) per metre. <IMAGE>

Title: Device for automatic registration and display of telephone costs
Inventor: SCHAEFER KLAUS
IPC: H04M15/28
Filed: 1982-06-09
Abstract: The invention relates to a device for automatic registration and display of telephone costs depending on the respective valid charge units and call times. In the known devices, a disadvantage for the user lies in that he cannot easily ascertain for himself the telephone charges accrued within a specific telephone call period. In order to offer a workable solution, it is proposed according to the invention to provide the parties to the call with enough time to decide whether the telephone call should be interrupted within the currently running charge unit or continued at the cost of one or more additional charge units. The invention is based on the problem of devising charging facilities for using the telephone system implemented here, which cater in simple fashion for the likelihood that the telephone users will make full use of the call duration per charge and thus per time unit. As a solution to this problem, it is proposed according to the invention to equip the device with an electronically controlled metering mechanism which acoustically or optically indicates the end of the call duration for the respective current charge unit in good time so that the parties to the call are given enough time to decide whether the telephone call should be interrupted within the currently running charge unit or continued at the cost of one or more additional charge units.

IPC: H01J17/49
Filed: 1982-09-30
Abstract: The invention relates to a gas-discharge panel having a gas-discharge space (10) and a post-deflection space which are separated from one another by a perforated control disc which is provided with line conductors (9) and column conductors. In the case of this device, it is intended to burn the gas discharge in a neat wedge shape from a large-area cathode (1) towards a selected line conductor ("line in use") and to switch it onwards line-by-line. In order that the non-selected line conductors (9) do not receive any erroneous currents which would brighten the image background, the invention provides for strip-shaped focusing electrodes (2 to 8) to be inserted in the gas-discharge space (10). These electrodes run parallel to the line conductors (9) and are interconnected in a digital manner to form two groups. The two groups receive different potentials which are negative with respect to the voltage of the line in use and are periodically interchanged in such a manner that the focusing electrode (2 to 8) located nearest in each case to the line in use is less negative. Main field of application: flat (television) screens. <IMAGE>
