Title: Leak detection of radioactive media esp. reactor cooling water - uses change in ratio of two nuclides of different half lives in surrounding atmosphere
Inventor: FICKERT WOLFGANG DIPL PHYS
IPC: G01M3/22
Filed: 1980-03-31
Abstract: A nuclide-specific activity measurement is carried out in the atmosphere adjacent to the ducting, at least two nuclides of differing half-life are distinguished and the relative proportions of these two nuclides are established; from the increase in the proportion of the short-life nuclide compared with the longer-life nuclide, an indication of a leak in the duct is obtd. Pref., the half-lives of the two nuclides differ by a factor of at least 10. Pref. nuclides are long-life nuclides: xenon 133. Short-life nuclide: Krypton 87 or xenon 138. Used for detecting leaks in the neighbourhood of ducts and other plant items esp. of water-cooled reactors. The method obviates the need for collecting drips of water themselves and carrying out measurements of them. Compared with this previous procedure, the new method is more accurate and involves less exposure of personnel to radioactivity.

Title: Method and apparatus for metering small quantities of liquid
Inventor: BROECHLER GERD
IPC: G01F11/02
Filed: 1981-05-25
Abstract: The invention relates to a method and an apparatus for metering small quantities of liquid using a pump with a piston-cylinder system, a pulse-controlled stepper motor for driving the piston, a valve for opening or closing an inlet passage and an outlet passage and a control, computing and comparison circuit for calculating the piston travel, and is intended, in particular, for use in analytical laboratories. The features of the invention are to be regarded as the fact that the distance actually travelled by the piston in the cylinder, which is, of course, affected by all the errors in the piston drive and in the piston movement, is detected by a length measuring device and converted into an electrical signal which is then evaluated in the control, computing and comparison circuit and compared with the calculated piston travel, whereupon, finally, the motor, triggered by the control, computing and comparison circuit, is supplied by a pulse generator with a number of pulses equal to or different from the number of pulses required to obtain the piston travel achieved, in accordance with the difference between the piston travel actually achieved and the calculated piston travel. The length measuring device with the movable sensor is arranged at a point in the apparatus which is affected by all the errors which occur.

Title: Device for heating food on board vehicles equipped with internal combustion engines
Inventor: HUNFELD HERMANN
IPC: B60N3/16
Filed: 1981-11-10
Abstract: The invention relates to a device for heating food, in particular meals and drinks, preferably coffee and tea, on board vehicles equipped with internal combustion engines. It has already been proposed to utilise the waste heat of the internal combustion engine when heating food on board buses in order to relieve the vehicle's electrical system. A tap-off of the cooling water circuit of the internal combustion engine is suitable for utilising the waste heat. However, with the proposed measures higher temperatures than the normal operating temperature of the cooling water circuit cannot be reached so that for example the preparation of coffee or tea for which the provision of boiling water is necessary cannot take place. According to the invention, a device of the previously designated type is provided which is characterised by a double-walled cooking vessel whose cavity located between the double walls is connected to a cooling water circuit of the internal combustion engine for the purpose of preheating the food and by an electric heating element which has an operative connection to the cooking space of the cooking vessel for the purpose of increasing the heating beyond the temperature of the cooling water circuit. The device according to the invention is thus suitable for heating meals and drinks on board vehicles, preferably buses, with advantageous utilisation of the waste heat of an internal combustion engine.

Title: Closure device for the nozzle head of an ink matrix printer
Inventor: REINDL PETER
IPC: B41J2/165
Filed: 1982-07-28
Abstract: In a closure device for the nozzle head (7) of an ink matrix printer, a flap (6) which is mounted rotatably and closes the nozzle head (7) is actuated by means of a lever device. This sequence of movement is delayed by a damping device (8) which acts on the lever device. In an arrangement of this type, the damping device (8) is to be designed in such a way that external influences, such as different spring forces and tolerances, temperature differences and bearing friction changes are ruled out to a great extent. This is achieved in that the damping device (8) is made up of a fixed body (16, 17, 18), which is connected to the frame (20) of the printer, and a rotary body (21, 22, 23) which is arranged so as to rotate about said fixed body (16, 17, 18), a grease which delays the sequence of movement being situated in the gap (27, 29) formed between the rotary body (21, 22, 23) and the fixed body (16, 17, 18). Due to the static friction thereby achieved between the rotary body (21, 22, 23) and the fixed body (16, 17, 18), different delay times can be achieved by different design of the two bodies. As a result, air which could impair the printer when the flap (6) is later opened can be prevented from being pressed into the nozzle head (7) by the flap (6). <IMAGE>
