Patent DE-3126579-A1 (DE)
Title: Electronically controlled, electromagnetic bell stroke
Inventor: PALIC JOHANNES
IPC: G10K1/34
Filed: 1981-07-06
Abstract: An electromagnetic bell stroke, having a bounce-free stroke, a high striking repetition rate and continuous volume control. This is achieved by the electromagnetic force acting directly on the striker, it being possible to fix precisely the switch-on duration of the magnet which is required to overcome the inertia and to accelerate the striker towards the bell via a control device, by means of a variable timer. Suitable timing selection ensures the level of freedom of the striker, selects the striking energy in accordance with the desired volume and achieves a high striking repetition rate by dispensing with mechanical force transmission and strike limitation, and makes mechanical adjustment superfluous. This striking method is used mainly in musical chimes.

Title: System for automatically removing dust which has settled in pipelines
Inventor: BILOUS BORIS
IPC: B08B9/035
Filed: 1981-10-30
Abstract: The subject of the invention is a system which automatically removes dust which settles in pipelines which serve to transport dust-containing gases such as illustrated in Fig. 1. For this purpose, on the lower part of the pipeline (1) openings (2) are provided through which the dust falls into funnel-shaped containers (3) which are welded gas-tightly onto the pipe. Through a collecting pipe (5) which is connected to a blower (9) by means of controlled shut-off valves (4), the dust is sucked in from the containers (3). The shut-off valves (4) are successively opened in each case for only one container (3) so that the dust can be extracted by the blower (9) at full power. The sucked-in dust is separated from the conveying air by a preseparating cyclone (7) and an end filter (8), as a result of which only pure air is extracted. This process can be controlled automatically. <IMAGE>

Title: Collision shut-off for a vehicle
Inventor: DUERWALD DIERK ING GRAD
IPC: B60T7/22
Filed: 1982-04-16
Abstract: The vehicle (1) running on three wheels (2) has contact bows (3) formed from segments on the front and on both sides. The ends of the contact bows are held by way of bearing eyes (19) arranged on the frame of the vehicle (1). Connected to these are two 45 DEG  sections (3.6 and 3.5) with a straight section (3.4), which essentially determines the length of the possible deformation of the front contact bow. Connected to this are two further 45 DEG  sections (3.3 and 3.2), which carry the middle section (3.1). This has a fixing point on each side in the form of a transverse web (13) for the attachment of a cable (5) by way of a clamping bolt (6). On the contact bow (3) deformed by collision and drawn in with a dashed line the contact bow end surfaces (4) of the sections bear on one another only with a line. In the process the cable is drawn from a winding reel (8) and presses a roller of a circuit breaker out of a switch detent of a bearing race of the winding roller (8) and switches off the drive motor of the vehicle. <IMAGE>

Title: Device for detecting magnetic one-component developer in duplicators
Inventor: STOTTMEISTER HANS-WERNER DR
IPC: G03G15/08
Filed: 1982-08-16
Abstract: The invention relates to a device which reliably detects the absence of magnetic one-component developer in the supply container, provided therefor, of duplicators, and signals this state to the user in good time. The aim of the invention is reliable detection of the undershooting of a critical threshold of the quantity of one-component developer in electrophotographic duplicators with the aid of simple means without interfering in the supply container. The object of the invention is to provide a scanning magnetic field which produces a different effect on an element, which records magnetic fields, as a function of the presence of the one-component developer. According to the invention, use is made for this purpose of a magnetic field generator, for example embodied as an electromagnet driven in a pulsed fashion and having at its pole end an element which records magnetic fields, e.g. a Hall-effect element, it being possible to use this arrangement in the form of a probe which is placed from outside onto the developer supply container. <IMAGE>

Abstract: Four plastic boards with the chess board imprint, of approximate size 180 mm times 360 mm times 2 mm, are assembled, at one of their lengthwise edges in each case, by means of elastic plastic strips, in such a manner that a cruciform device is formed. 32 round or square holes are punched in each of the plastic boards. The device can be folded closed like a book, and opened at any point to give an open double spread. The men consist of three stamped-out blanks, which are round or square, the central blank having a sickle-shaped cut-out, and the cavity thus formed between the three blanks being used for inserting the chess-man blanks into the edges of the holes of the boards of the device. The chess-man blanks have a gripping knob on each of their two flat sides. The bookcase-format crosswise chess set permits genuine three-dimensional chess. The device is folded open in the form of a cross, and a chess player sits at each of the four cross parts of the device. The first two vertical rows of the intersections are occupied by the pieces and the row of pawns. Each of the players play simultaneously against two other players. For example: the players white and yellow sit opposite, and the players red and blue also sit opposite. White's first move is made against red and blue simultaneously. When, for example, white's men have reached the 90 degree line of red, sitting to his left,... Original abstract incomplete.

Title: Diaphragm non-return valve with downstream atomiser nozzle, especially for use on sprayer booms for spraying plant protection agents
Inventor: GROTHE WOLFGANG
IPC: B05B1/32
Filed: 1983-03-05
Abstract: The valve has a valve seat formed as a pipe stub and a diaphragm cooperating with the valve seat as a valve closure body and held in abutment by spring pressure against the valve seat and which can be lifted from the valve seat only at a given pressure of the liquid to be sprayed and by this itself, the path for the liquid to the downstream atomising nozzle then becoming free. The diaphragm, consisting of plastics, is itself constructed as the spring. In a diaphragm non-return valve constructed in such a manner, the diaphragm simultaneously takes over the functions of force transmission, obturating element, and opening and closing element. The pressure plate, securing ring and separate compression spring required in the prior art diaphragm non-return valves can hereby be omitted. A compact, easily produced and light diaphragm non-return valve is thus provided, which is easy to integrate into the overall equipment (e.g. a sprayer boom).

Title: Process for transferring heat from a hot SO2-containing flue gas to the cold desulphurised clean gas
Inventor: WEIGEL MANFRED
IPC: B01D53/00
Filed: 1983-04-19
Abstract: To transfer heat from a hot SO2-containing flue gas, prior to its desulphurisation at low temperature, to the cold desulphurised clean gas prior to discharge to the stack, the heat to be removed from the hot flue gas to cool it to the inlet temperature of the desulphurisation plant is transferred to air using a liquid or vaporisable heat carrier and the thus preheated air, following further heating with hot flue gas, in a relatively small portion is added to the desulphurised cold gas, while the remaining fraction is used as combustion air. The use of high-grade corrosion-resistant material is restricted to the flue gas cooling stage prior to desulphurisation. The flue gas cooler can be minimised in area at the expense of the air preheater. The heat removed from the flue gas in the low temperature range is utilised for high pressure steam generation in the boiler plant.

Title: Buoyancy body for diver counterbalancing
Inventor: HASENMAYER JOCHEN
IPC: B63C11/30
Filed: 1983-05-28
Abstract: During diving with breathing apparatus, inflatable buoyancy bodies are used to control the upthrust and downthrust. They are to act on the diver in a neutral manner with respect to equilibrium, they are to be fluidically advantageous and are not to impede movement, and they are to have sufficient capacity even for large equipment. The object is achieved by the invention by it integrating a flexible, inflatable casing (2) in the outer form of the pressure-gas cylinder (1) of the breathing apparatus in such a way that it performs the function of a second inflating outer skin of the cylinder (1). Embodiments with an elastomeric casing, a casing resistant to internal pressure, a multi-chamber casing and multi-chamber casings with control of the filling proportions are further developments of the invention and extend the range of use of the diver counterbalancing system. <IMAGE>
