Title: Alarm clock
Inventor: STEMME WALTER
IPC: G04C21/20
Filed: 1983-01-27
Abstract: There is specified for an alarm clock having an electrically driven alarm transducer an alarm contact device which has a make contact (7) and an associated mating contact (5). When there is agreement between the set alarm time and clock time, the alarm circuit, which drives the alarm transducer, is closed for a definable period for the purpose of emitting an alarm signal by the make contact (7), which is controlled as a function of time. During this period, the alarm circuit can be reinterrupted manually by the user of the alarm clock by a deflection of the mating contact (5) which is performed perpendicular to the direction of movement of the make contact (7). Because of the design according to the invention of the alarm contact device, after a manual interruption of the alarm circuit first the make contact (7) and then the mating contact (5) automatically turn again to their initial position within the same period. As a result, 12 or 24 hours after emitting an alarm signal the alarm clock will automatically re-emit an alarm signal in each case without any preparation on the part of the user. <IMAGE>

Title: Device for filling cans
Inventor: WENZEL WERNER ING GRAD
IPC: A22C25/00
Filed: 1983-02-16
Abstract: A monitoring device for feeding cans to a device for filling cans is proposed which advances the filling material, in the present case fish, in manually filled troughs. The cans are transferred by means of a push-in device to a can conveyor which is driven synchronously with the conveyor carrying the troughs, the push-in device being actuated by a cam which operates synchronously with respect to the advancing movement of the troughs. To ensure that a can is not assigned to unfilled troughs, the filling of the troughs is monitored by a sensor which controls a lock arranged between the push-in device and the cam in dependence on the switching signal of the sensor.

Title: Process for making waterproof tiles from gypsum, and casting mould
Inventor: QUANTE HEINRICH
IPC: C04B24/16
Filed: 1983-05-20
Abstract: Glazed tiles of gypsum are considerably more stable dimensionally than those of ceramic or porcelain. At the same time, they become waterproof and are given an adequate bending strength, if they are made from an aqueous suspension of alpha-gypsum hemihydrate, sulphate slag cement and aluminium sulphate and put into a tile-shaped mould, whereupon the suspension is defoamed during setting in the mould by means of vibrations, for example ultrasonically, and then released from the mould after the setting process, and if appropriate, also provided with a surface coating. Glazed tiles having optimised strength properties and also other values are here obtained in particular if the suspension is introduced as part fillings which are each defoamed individually and can have different compositions. <IMAGE>
Patent DE-3322244-A1 (DE)
Title: Intrinsically safe power source
Inventor: AUGUST GEORG
IPC: H02H9/00
Filed: 1983-06-21
Abstract: An intrinsically safe power source is proposed, which is used for supplying power to n loads (R1 ...) and whose currents are limited by current limiter circuits (12) which are connected in series. The circuit according to the invention is constructed in such a manner that, in the event of a permissible defect 1, a first current limiter circuit (12) has a first response current (IA1) of a magnitude equal to the sum of the specified load currents (I1 + I2 + I3). Parallel-connected current limiter circuits (14, 15, 16), the number of which corresponds to the number of loads (R1, R2, R3), are connected on the input side to the first current limiter circuit. The sum of the response currents (IA2, IA3, IA4) of the current limiter circuits (14... 16) is greater than the response current (IA1). The individual response currents (IA2, IA3, IA4) are, however, less than the first response current (IA1). The intrinsically safe power source manages with few current limiter circuits, and the serviceability of the individual current limiter circuits can be tested at the outputs of the power source. <IMAGE>

Patent DE-3346988-A1 (DE)
Title: Spreader
Inventor: METZELER WOLFGANG DIPL ING
IPC: B66C1/66
Filed: 1983-12-24
Abstract: The spreader 1 is designed in such a way that it rests on the container only with the flat bearing pieces 2. With a bolt 6 the connecting means 4 engage in the location openings 5, arranged at the top and side, of the container. In the process, the bolt 6 is driven by the working cylinder 8. The type of construction results in the advantage that the spreader 1 does not significantly increase the height dimensions for road haulage so that road travel can always take place with a spreader loaded on the container. The additional width dimensions which arise in the case of the novel spreader have virtually no adverse effect on road haulage. <IMAGE>

Title: Anti-jackknifing control
Inventor: REICHL BERNHARD DIPL ING
IPC: B62D53/08
Filed: 1984-02-18
Abstract: Preferably double-acting piston/cylinder assemblies serve to provide anti-jackknifing control for articulated vehicles, in particular articulated buses so that, when appropriate, an undesired increase and an undesired decrease in the articulation angle can be counteracted. As a function of the travel speed V, an articulation angle limit value K max (V) is determined at which an essentially slip-free travel state can still be present at the respective speed V. The articulation lock of the articulation joint is then controlled in such a way that the articulation angle is then limited to the articulation angle limit value if the steering wheel is turned to a high degree, increasing the steering angle, so that an essentially higher articulation angle would be produced if slip-free circulatory movement were assumed which, however, is no longer possible at the respective speed. <IMAGE>
