Patent DE-3113915-A1 (DE)
Title: Device for limiting the lateral pivotability of the lower links of a mounting linkage for working appliances of tractors which can be used for agricultural purposes
Inventor: MUELLER HUBERT
IPC: A01B59/041
Filed: 1981-04-07
Abstract: In a narrow-track tractor, the lower links of the mounting linkage for working appliances are articulated on a bearing bracket fastened to the tractor frame. The lower links are connected by articulation, via supports attached in a fork-like manner, to cranks (8) arranged vertically in the vicinity of the tractor centre. The cranks are mounted on the bearing bracket in such a way that they move in opposite directions in a vertical longitudinal plane of the tractor when the lower links pivot laterally in the same direction. So that the lateral pivotability of the lower links can be limited, there is inserted into a recess of the bearing bracket a pressure-medium cylinder, the piston of which cooperates with a plunger which can be pushed into the path of movement of the cranks. The pressure-medium cylinder can be loaded via a control valve and can be blocked in the actuated state by means of a shut-off valve arranged behind the control valve, but parallel to a pressure-medium insert cartridge for the supply of further pressure-medium consumers.

Patent DE-3116195-A1 (DE)
Title: Device for producing a hot-gas jet
IPC: F23D14/64
Filed: 1981-04-23
Abstract: For producing hot-gas jets by means of flames, usually a mixing chamber and a downstream combustion chamber are used, which latter is adjoined by a tube sleeve for mixing the hot combustion gases with air. According to the invention, downstream of the said mixing chamber is a further chamber, in which a further improvement of the mixture occurs, so that the flame can be formed after the further chamber. To keep it constantly at the outlet from the further chamber, the further chamber is provided with a cross-section which becomes increasingly flatter and with an outlet gap, parallel to which a bar of rather smaller thickness is arranged. The further chamber is in this case designed in terms of flow in such a way that, with the tube sleeve it forms a diffuser by being fitted into the tube sleeve, the diameter of which is of a corresponding size. Consequently, the flame gases mix over an extremely short distance with air taken in through the tube sleeve, so that the device is easy to handle.

Patent DE-3123040-A1 (DE)
Title: Magnetically screened cable having a screen consisting of soft-magnetic material
Inventor: BOREK LEOPOLD DIPL ING
IPC: H01B11/10
Filed: 1981-06-11
Abstract: In order to keep magnetic interference fields (constant fields or fields at a low frequency) away from electrical cables, it is known for strips consisting of magnetic conductive material having a high permeability to be wound around the cable. In this case, the problem exists on the one hand of being able to keep the cable flexible and on the other hand ensuring, despite the deformation of the screen material occurring during winding, that the soft-magnetic properties of the material are maintained as well as possible. In order to solve this problem, according to the invention, a strip (4) of amorphous material is wound around the cable (1), such that an air gap (7) is in each case present between adjacent turns (5, 6) of a strip. A second strip (8) is applied in a similar manner, in the opposite direction, onto this first strip (4). In consequence, a good screening effect is achieved, with good flexibility of the cable at the same time. <IMAGE>

Title: Safety circuit for a burner for gaseous or liquid fuels which is operated by a fan (blower)
Inventor: BUGL HANS
IPC: F23N5/20
Filed: 1981-07-06
Abstract: Safety circuit for a burner for gaseous or liquid fuels which is operated by a fan and has a flame monitor (Fl) and a master switch (HS) which switches on the fan. A wind monitor (WS) monitors the supply of air and makes the operating voltage (U) available by its response to an igniter (Z) and a solenoid valve (M) for feeding the fuel after expiry of a preliminary time. Given maintenance of the operating voltage (U) by the wind monitor (WS), a first relay (H) is activated for a first time interval (t0-t1). With its response, said relay prepares the activation of a second relay (E) in such a way that upon release of the first relay (H) the second relay (E) responds, connects itself into a hold circuit and effects the stepping of the operating voltage. Upon expiry of a second time interval (t1-t2), the first relay (H) is reactivated for the duration of a third time interval (t2-t3), and thus the operating voltage (U) is switched through to the igniter (Z) and the solenoid valve (M). The solenoid valve (M) is provided with a hold circuit which depends on the second relay (E). The first relay (H) is switched off either upon expiry of the third time interval or by the flame monitor (Fl) upon detection of the flame. <IMAGE>

Patent DE-3214596-A1 (DE)
Title: Suspension device for lighting fixtures
Inventor: BAETZ RUDI
IPC: F21V21/112
Filed: 1982-04-20
Abstract: The invention relates to a suspension device for lighting fixtures, especially having fluorescent lamps. To date, use has been made as connecting elements between in each case one cable or the like and the lighting fixture, of multipart fixing brackets whose individual parts are connected to one another by screws upon assembly of the lighting fixture. This is cumbersome and, moreover, the screws can easily be lost. The invention proposes for the purpose of solving this problem to make use of, instead of the above connecting elements, suspension pieces (15) having a U-shaped cross-section whose longitudinal rims are constructed as support flanges (19) and which have rectangular recesses (20) on diagonally opposite end regions, a diagonal spacing between the perpendicular rims (21) of the recesses (20) being dimensioned larger to a slight extent than the smallest width of a longitudinal groove in a support rail of the lighting fixture to be suspended. The suspension pieces (15) can therefore be mounted in a simple way. All that is required is to plug them obliquely into the longitudinal groove of the lighting fixture support rail and rotate them by approx. 30 to 40 DEG  until the suspension pieces (15) snap resiliently into their installed position, which is axially identical to the support rail and in which the support flanges (19) grip from below inwardly projecting longitudinal rims of the longitudinal groove in the lighting fixture support rail. The invention is principally used in suspending a multiplicity of lighting fixtures to form so-called lines of fluorescent luminaires. <IMAGE>
