Title: Circuits, apparatuses equipped therewith for rechargeable batteries, especially battery lamps, and holders for them
Inventor: SORGATZ WOLFGANG
IPC: H02J9/02
Filed: 1982-03-17
Abstract: The invention relates to circuits, to apparatuses equipped therewith for rechargeable batteries, especially battery lamps and warning lights, and holders for them. For example, battery lamps with primary batteries have the major disadvantage that they are generally not ready to use when needed, because the batteries have discharged in the course of time, or have even run out, and the relatively expensive batteries must be replaced, which is furthermore linked to holding of stock, interchangeability etc. The present invention proposes a simple basic circuit which is used both as an electronic fuse in the holder as well as in a modified version in battery lamps as a flashing light additional circuit, automatic dimming unit and/or automatic emergency current elimination unit, in conjunction with the automatic charging unit for rechargeable batteries. The main fields of application are working lights, emergency lights and warning lights of all types for traffic and safety. Furthermore, a holder which is proof against short-circuits has been developed for these cost-effective apparatuses, which are always ready for use, into which holder the respective apparatus can be inserted for recharging, in the correct polarity, so that a simple, safe handling is ensured. <IMAGE>

Title: Panel element
Inventor: KUEPPER ERWIN
IPC: E04D13/16
Filed: 1983-02-23
Abstract: Arranged on the web 1 of a panel element are two lateral flanges 2 and 2' possessing, at their upper ends, horizontally inward-bent legs 3 and 4. These legs 3, 4 bound the foamed material 10. One leg 4 of the flange 2' is constructed to run in opposite direction and its projection 5 projects beyond the leg 3 of the other flange 2. As a result of this construction, the joint between two adjacent panel elements is covered at the top. This cover is improved further by a spike 6 arranged at the end of the projection 5 so as to point obliquely downwards and engaging in the foamed material 10. As a result of the foamed material 10, for example polyurethane, foamed in the panel element, an intimate bond results, so that a lightweight prefabricated part which is simple to install is produced. The panel elements rest on so-called Z-sections 8; 9 fixed to the supporting structure. <IMAGE>

Title: Actuation mechanism for the tongues of the points of a toy railway
Inventor: HERZER KUNO
IPC: A63H19/32
Filed: 1983-03-21
Abstract: The actuation mechanism for the tongues of the points of a toy railway is mounted below the table-top bearing the track system so that a pin connects the armature, which can be moved backwards and forwards manually or under remote control, to the tongue slide of the points. The subject of the invention is characterised mainly by the fact that a lever which is coupled to the armature is coupled to the tongue slide (e.g. a connecting arm) by means of a coupling element, for example a rotatable vertical shaft, and that the coupling is mounted in a centred fashion indirectly in sheaths (e.g. in a plug-in element) in a bore hole in the table-top. One of the advantages of this design for the model railway enthusiast consists in the fact that simple round boreholes in the support plate are sufficient for assembly. <IMAGE>

Title: Piston pump with intake-side delivery control as a function of the delivery pressure
Inventor: MATTHEES KLAUS DIPL ING
IPC: F04B1/28
Filed: 1983-07-01
Abstract: The invention relates to a piston pump having a plurality of delivery pistons with constant stroke arranged in cylinder bores around the centre axis and actuated by an axially acting stroke device, and an intake chamber centrally arranged in the pump housing between the cylinder bores and defined by a control valve, the control valve being axially displaceable by means of a control element acted upon by the delivery pressure against the force of springs. The aim is an improved overall control characteristic. At the same time constant pressure control is to be realised. To this end, a piston pump has been created in which a control cylinder is arranged in the inner chamber of the pump housing and has throttle cross-sections for the individual inflows to the respective delivery units. These throttle cross-sections are covered or freed in relation to the common intake chamber by means of the bottom edge of the control valve as a function of the delivery pressure. The piston pump according to the invention is preferably suited for operating conditions in which a constant delivery pressure is necessary throughout. At the same time, an infinitely variable delivery control as a function of the delivery pressure is achieved. <IMAGE>

Title: Method and device for generating colour content signals
Inventor: LENTZE FELIX DIPL ING
IPC: G01J3/51
Filed: 1983-08-03
Abstract: A method and a device for generating colour content signals are intended for detecting the chromaticity of a surface region of an object independently of fluctuations in illumination. For this purpose, three colour contents are generated by filtering from radiation emanating from a surface region (1) of the object (2), and converted into electrical colour content signals. The colour content signals are combined to form an aggregate signal which is compared as actual value of a controlled variable with an adjustable desired value in order to form a system deviation. The magnitude of all three colour content signals is changed to the same extent in accordance with the system deviation in order to reduce the system deviation to zero or to a very low value. <IMAGE>
