Title: Fuel consumption indicator
Inventor: LEHNERT GUNTER ING GRAD
IPC: G01F1/36
Filed: 1982-05-14
Abstract: A fuel consumption indicator for motor vehicles having an internal combustion engine with intake manifold has a partial vacuum meter (11, 11') with a first partial vacuum switch (12, 12') which is closed above a partial vacuum in the intake manifold corresponding to a low fuel consumption and is otherwise open. An engine speed meter (13) has two engine speed switches (14, 15), one (14) of which is closed above a first engine speed (n1) which is located at the start of an engine speed range which is favourable for consumption and the second (15) of which is closed above a second engine speed (n2) which is located at the end of the engine speed range which is favourable for consumption, both switches being otherwise open. An evaluation unit (16) comprises a logical connection circuit with three digital outputs (17, 18, 19), one (17) of which only receives a signal when the partial vacuum switch (12, 12') and the first engine speed switch (14) are closed and the second engine speed switch (15) is open, the third output (19) of which only receives a signal when the partial vacuum switch (12, 12') is opened and the two engine speed switches (14, 15) are both opened or both closed, the second (18) of which receives a signal in all the other switching states of the three switches (12, 12'; 14, 15). The consumption indicator instrument (20) has three different signal generators (21, 22, 23; 55, 56, 57) which emit visual and/or audible signals. <IMAGE>

Title: Method and device for the operation of a throughflow dryer for printed materials
Inventor: WEBER ERICH
IPC: B41F15/12
Filed: 1982-05-28
Abstract: A throughflow dryer for printed materials is concerned, especially for screen-printed sheets (6) which are successively fed, spaced apart, to a conveyor belt (7) set in motion by a drive motor (10) and running through the dryer housing (1,2). The printed sheets (6) were hitherto generally transported through the dryer (1,2) on a continuously circulating conveyor belt (7). In contrast to this, according to the invention the conveyor belt (7) is moved forwards discontinuously by the drive motor (10), in step with the printed sheets (6) reaching the dryer inlet (3), in each case by a distance corresponding at least to approxiamtely the length measurement of the printed sheet (6) concerned. The switch pulses to start and stop the conveyor belt (7) can, for example, be emitted by means of a photocell (13) responding to the front edge or rear edge of a printed sheet (6) reaching the dryer inlet (3). The conveyor belt (7) is thus only advanced when a newly arriving printed sheet (6) has to be transported. The capacity of the dryer is better utilised as a result. <IMAGE>

IPC: H04N9/802
Filed: 1982-11-13
Abstract: The regeneration of additional identification signals in the reproduction of stereo, mono or 2-channel recordings with video recorders for stereo sound recording is carried out according to the teaching of the main application P 3238399.1, for example with the aid of a circuit for evaluating the degree of correlation of the different multi-channel sound signal types. The subject matter of the present invention is a circuit device for degree-of-correlation evaluation, which is designed specifically for the requirements of regenerating these additional identification signals for the different stereo, mono and 2-channel sound signal types, which at the same time incurs little expense. A differential amplifier with downstream threshold value detectors is used. Further developments concern the setting and balancing of the threshold value detectors and the use of devices for dynamic compression for the purpose of stabilising the separation criteria for the different sound signal types by eliminating the effect of the absolute levels. Further embodiments of the invention relate to the insertion of the degree-of-correlation evaluation circuit as a component in a video recorder, a television receiver or an additional device for programme selection, mixing and cross-fading purposes in audio or audio/video systems.

Title: Liquid filter for reversible pressure direction or flow direction
Inventor: BERNHARDT BERND
IPC: B01D35/15
Filed: 1983-04-13
Abstract: Starting from known liquid filters for reversible pressure direction or flow direction having non-return valves with sprung valve discs in a Graetz circuit, it is now proposed according to the invention to form the non-return valves and the connections between them as bores in a valve block (4). The assembly of such a liquid filter is considerably simplified as a result, and the pathways between the non-return valves can be shortened and designed in such a manner that as low as possible a resistance to flow results. By means of certain dimensions of the valve bores and the connection bores between them, the resistance to flow can accordingly be minimised. <IMAGE>
