Title: Central heating automatic temp. electrical control circuit - uses thermostatic valve on each radiator, connected to max selector stage for regulation
Inventor: BOEHM LORENZ DIPL ING
IPC: F24D19/10
Filed: 1980-09-29
Abstract: The central heating circuit with a boiler (1) connected by a mixer valve (5) and pump (8) to a series of radiators (W1-W3), has the return flow from the radiators passed through the mixer valve. The individual return lines (-11) are connected to a common return line (6). The hot water supply line (7) with a proportion of the return flow is connected by individual thermostatic valves (V1-V3) to the radiators, connected to a temperature control system. Normally the valve which is open by the greatest amount passes an electrical signal to a maximum selector stage (12) and a control unit (13) so as to control the temperature of the hot water to the radiators with that valve fully open. The system also controls the heat supply to the boiler.
Patent DE-3102719-A1 (DE)
Title: Device on bicycles or on bicycle-like frames for learning how to ride a bicycle
Inventor: VATTER ERNST DIPL ING
IPC: B62H7/00
Filed: 1981-01-28
Abstract: In order to keep his balance, a bicyclist or motorcyclist always steers his handlebars towards the side to which he believes he may tip over. The inertia of his body weight in motion counteracts such directional changes and shifts the centre of gravity of his body weight and hence the tilting moment to the other side. With the device for which a patent has been applied for, it is possible for the learner, in the same way as when moving, also in the standing position to shift the centre of gravity of his body weight to the left or to the right by turning the handlebars and, by this means, to practice keeping his balance. This object is achieved according to the invention in that the steering column, connected to the handlebars, is extended in place of the front wheel and its pivot on the ground is only secured to the extent that it cannot be laterally displaced, while the load is transmitted to the ground by a roller which is placed transversely with respect to the notional direction of travel and is held via a lever arm which projects forwards and is rigidly connected to the steering column. By this means, a two-point support which is composed of the rear wheel and the roller and is unstable to the left and to the right is preserved; this support, however, can be stabilised by correspondingly displacing the roller.

Patent DE-3134566-A1 (DE)
Title: Drive device, especially for washing machines
Inventor: ROMBACH HUGO
IPC: D06F37/36
Filed: 1981-09-01
Abstract: In a drive device, especially for washing machines, two concentric belt pulleys of differing diameter are mounted freely rotatably on a hub designed to be coupled to a drive source, whilst essentially radially movably guided flyweights, spring-loaded towards the axis of rotation and carrying coupling elements for the large and the small belt pulley, rotate together with the hub. When the flyweights are in a radially outer position, the hub is coupled to one (the large) belt pulley by means of coupling elements arranged on the flyweights, whilst, when the flyweights are in a radially inner position, the other (smaller) belt pulley is connected fixedly in terms of rotation to the hub via such coupling elements of the flyweights. A randomly trippable retention device having a trip element actuatable from outside makes it possible to lock the flyweights in the radially inner position. In order to achieve silent operation, along with low wear and a long lifetime and along with a simple construction, the retention device (20, 26, 18) has a control device (30, 41) which automatically acts dependent on rotational speed and by means of which the flyweights (13) can be held in a middle position, in which the coupling elements (17, 18) are out of engagement with their two belt pulleys (3, 21). <IMAGE>

Title: Device for determining the location of a track-bound vehicle
Inventor: JUNG MARTIN ING GRAD
IPC: B61L25/02
Filed: 1982-01-13
Abstract: In order to determine the position of a track-bound vehicle (F), marks (M) which can be read by the vehicle are arranged always at identical distances (k) along the route (S) travelled over by said vehicle. These marks have an effective length which is equal to half the distance between the marks; the front edge and the rear edge of the transmitted signal are evaluated separately. In order to read the marks, a plurality of reading devices (E1, E2, E3) is arranged one behind the other on the vehicle in the direction of travel. The distance (a) of the reading devices from one another is dependent on the distance (k) of the marks (M) from one another and the number (x) of reading devices. By means of suitable dimensioning of these values, it is possible to determine the position on the vehicle in a way that is very much more precise than the route resolution given by the distance (k) of the marks from one another. The device according to the invention is provided in particular for the highly accurate positioning of the pusher carriages in coking plants. <IMAGE>

Patent DE-3208819-A1 (DE)
Title: Driving and brake control for a locomotive remote-control radio transmitter
Inventor: STEIN HERMANN
IPC: B60L7/00
Filed: 1982-03-11
Abstract: The driving and brake control for a locomotive remote-control radio transmitter has a driving/brake control switch with a plurality of driving switching positions for different driving operating states and a plurality of brake switching positions for different brake operating states. A safety driving control which has to be repeatedly activated in the driving switching positions of the driving/brake control switch by switching over the driving/brake control switch emits a warning signal after a first safety period has elapsed and after a second safety period has elapsed triggers the braking operation. In order to activate the safety driving control, the driving/brake control switch comprises two adjacent driving switching positions (d, dd) for the driving instruction ''constant driving power'', one driving switching position (dd) of which activates the safety driving control. When manually released, the driving/brake control switch is automatically switched by a spring out of this driving switching position (dd) to the other driving switching position (d) for constant driving power. After a switching position (a) which applies the brake has been switched on, a safety brake control inhibits the switching positions (c, d, dd, e) which control the driving operation. A further switching position (aa) which also applies the brake and releases the safety brake control is provided adjacent to the brake switching position (a). <IMAGE>

Title: Reversing device for the automatic reversing of a piston-cylinder unit, in particular of a plough-turning cylinder
Inventor: BRANDENBURGER WALTER ING GRAD
IPC: A01B3/421
Filed: 1982-04-02
Abstract: The invention relates to a reversing device for the automatic reversing of a piston-cylinder unit, in particular of a plough-turning cylinder, with a spring-loaded reversing piston and a pilot valve which controls the reversing piston and is held in the shut position by a spring until a sufficient opening pressure is reached. Since systems of this type have to work at both different inflow pressures and different inflow quantities, problems occur in such a way that this opening pressure is already reached during the first stroke phase and premature change-over takes place. To avoid premature change-over, the pilot valve is therefore provided with two additional effective areas which support the spring. One effective area is permanently connected to the feed line and is slightly smaller than the one effecting the opening.

Patent DE-3239922-A1 (DE)
Title: Method and device for winding webs of fabric, especially glass fibre mat
Inventor: CICHON ERWIN
IPC: B65H19/26
Filed: 1982-10-28
Abstract: Very high propulsive outputs, leading to high levels of stress for webs of fabric, have hitherto been seen as indispensable for winding of webs of fabric, especially webs of glass fibre fabric, by means of a winding machine with a pressure contact roll and a central winding drive to produce a hard, easily transportable roll. The tensile force can be reduced in the method according to the invention. The tensile force is reduced in relation to the increase in roller diameter. The pressure of the pressure contact roll will be kept constant throughout the winding process, substantially at least. This pressure therefore corresponds essentially to the tensile force measured in the winding tube at the start of the winding process. In addition, winding takes place round at least 120 DEG  of the pressure contact roll during the winding process. The pressure contact roll is simultaneously retarded. A winding method of this kind yields especially good winding results.

IPC: G06F11/26
Filed: 1982-11-08
Abstract: A test device for testing assemblies containing microprocessors essentially consists of a pattern of the assembly to be tested, which, in particular, also contains the "original software" of the device under test so that this forms the basis for the test. This results in very short testing times and in testing to a great depth. Using function generators provided in the test device, stimuli can be generated which correspond to those of the proper application of the device under test. This provides for a test which corresponds to the conditions of use of the device under test in every respect, that is to say both with respect to the operating speed and with respect to the functional variety.

Title: Dry sorption filter for chemisorption of noxious gases and adsorption of hot dusts
Inventor: WETTERMANN HARRY
IPC: B01D53/68
Filed: 1982-12-23
Abstract: The invention relates to equipment which enables the use of granulated solids for dry chemisorption of noxious gases. Moreover, hot dusts can be filtered out and heat recovery can be operated without additional heat exchangers. Use is predominantly made of lime chips, particle size 2-8 mm. The granules are continuously regenerated when fouling hinders the chemisorption. Dust and abraded material are separated off and removed. All processes proceed automatically, so that a reduced expenditure on maintenance is necessary. The equipment is constructed in such a way that the exhaust gases have to flow through a vertical packed bed, which is bordered at the side by a ribbon grille. A metering shaft delivers the granules evenly over the entire length and transports the masses into a screen and feed drum in which fine material is separated off and discharged. In this case, abrasion of the particle surfaces takes place. Unused material is returned to the circulation. A plurality of beds are combined to form a system, so that one packed bed is constantly in the regeneration phase. The process is suitable in particular for fluorine and chlorine sorption at salt firing furnaces. Fig. 1 shows the overview of the entire arrangement. <IMAGE>

Title: Enclosure for accommodating a number of loudspeakers
Inventor: GABRIEL HARALD
IPC: H04R1/02
Filed: 1982-12-28
Abstract: To prevent so-called standing waves in the case of parallel wall surfaces of conventional loudspeaker enclosures, an asymmetric enclosure form is implemented which results from the application of non-parallel wall surfaces. This contributes to a decisive improvement in the quality of reproduction and to an increase in the efficiency. By splitting the enclosure into components as shown in the example of an application, an influence of the natural vibrations of the loudspeaker enclosure on other tone ranges can be prevented, although the invention also relates to all other types of loudspeaker box construction having a uniform enclosure design.
