Patent DE-3704143-A1 (DE)
Title: Joint coupling
Inventor: RUEHMANN GERD DIPL ING
IPC: F16D3/30
Filed: 1987-02-11
Abstract: Technical problem of the invention: Creation of a low-wear connection of short overall length with large flexing angles between gearbox and rear axle of commercial vehicles. Solution to the problem: Gearbox (12) and rear axle (11) are connected to one another by way of a joint coupling. The joint coupling has two homokinetic spherical plane bearings, one (1) of which is fixed on the transmission output shaft (3) and the other (2) on the rear axle inlet shaft (4). The spherical plane bearings are provided on their outer rings with spline-shaft tooth systems, which engage in the corresponding internal toothing of a sleeve (5), which connects the spherical plane bearings (1 and 2). The bushing (8) is supported on the outside diameter of the right-hand component by way of the slide bearings (6, 7). The tubes (9, 10) essentially covering the sleeve (5) are firmly fitted on the bushing (8), to which tubes the bellows (13, 14) are in turn fixed, which are connected to the transmission and to the rear axle housing. The positioning link (21) is pivoted on the bushing and the rear axle housing (11), as is the support link (20). Sphere of application: Connection of drive elements, especially of gearbox and rear axle in commercial vehicles. <IMAGE>

Patent DE-3728225-A1 (DE)
Title: Inking unit
Inventor: JENTZSCH ARNDT DIPL ING
IPC: B41F35/04
Filed: 1987-08-25
Abstract: The invention relates to an inking unit, consisting of an ink distribution device and a number of inking cylinders and inking rollers. The aim of the invention is to provide a device on inking units, with which the time for adjusting the quantity of ink required is shortened and the occurrence of waste is thus also reduced. The object consists in rapidly reducing excessive ink feeding within the inking cylinders and inking rollers using a device which is simple to produce and to operate. According to the invention, this is achieved in that an ink-free roller assembly can be engaged briefly on a distributing cylinder, a cleaning device being assigned to said roller assembly. <IMAGE>
Patent DE-3729922-A1 (DE)
Title: Radio link with device to improve the signal-to-noise ratio
Inventor: VOGEL KLAUS DIPL ING
IPC: H03G3/20
Filed: 1987-09-07
Abstract: In the case of a radio link, large level differences can occur between adjacent channels at the input of a directional radio receiver in particular radio-field conditions (selective fading). In the case of a high active-channel level and an even higher adjacent-channel level, this can lead to the controlled receiver stages being overdriven by the large adjacent-channel signal. In order to avoid such interfering influences, the invention provides two control loops in the receiver, which control loops are connected in series in the signal path and each consist of an attenuating element (3, 7) and a probe (5, 9). The first control loop (3, 5) prevents a predetermined overall level value being exceeded, and the second control loop (7, 9) prevents a predetermined active-channel level value being exceeded. <IMAGE>

Patent DE-3731490-A1 (DE)
Title: Continuously variable transmission
Inventor: EMMER RUDOLF
IPC: B41F13/00
Filed: 1987-09-18
Abstract: A description is given of a continuously variable transmission which can provide a continuously variable output - with variation down to zero - at its output shaft from speeds input at its input shaft. For this purpose, the invention proposes a hollow input shaft on which is arranged, parallel to it, an eccentrically adjustable spigot (1) which acts on connecting rods and crank arms. These transmit its pivoting motion to spindles (4) which in turn, via free wheels, gear wheels, toothed belts and the like, establish a connection to the output shaft. By varying the eccentricity of the spigot (1) relative to the centre of the hollow input shaft, variation of the output speed is achieved, in particular with an eccentricity down to 0. The transmission can be regulated through its hollow input shaft by adjusting this eccentricity (Figure 1). <IMAGE>

Title: Safety device for graphite moderated nuclear reactors
Inventor: RIECKMANN PETER DR
IPC: G21C9/02
Filed: 1988-04-07
Abstract: When a nuclear reactor runs away, which can arise through failure or faulty operation of the control rods (Chernoby), it is then always connected with a rapid and considerable temperature increase. It is proposed to provide the control rods with a suspension which is released in the case of a temperature rise. The control rods then fall into the reactor and thus close it down. This device cannot be influenced from outside and therefore safely excludes chance or "human" error.

Title: Roller blind
Inventor: SCHOMMERS ROLF
IPC: E06B9/174
Filed: 1988-04-09
Abstract: Roller blind having a rotatably mounted winding-up shaft (3) for the interconnected roller-blind bars which form the shutter (6), having two lateral guides for the shutter which can be unrolled and wound up, and having a double-thrust drive which rotates the winding-up shaft and is intended for winding the shutter onto the winding-up shaft and unwinding it therefrom, the winding-up shaft, with the respective shutter roll, being located within a roller-blind casing (1), which encloses it wholly or partially, and the shutter being enclosed by a part which forms an arc of a circle and exhibits a through-passage opening for the shutter which is to be unwound.

Title: Circuit arrangement for the monitored operation of two AC loads via a common supply line
Inventor: RECHENBACH KARL-HEINZ
IPC: H02J13/00
Filed: 1988-04-22
Abstract: A circuit arrangement is specified which enables the supply and monitoring of two AC loads (rtH, rtN), of which the second comes into operation automatically in the event of the first failing, from an actuating mechanism via a common two-wire supply line. The two loads are supplied asymmetrically with respect to the polarity of the AC half-cycles. The actuating mechanism tests for the presence and the orientation of the asymmetry in the supply current. The asymmetry is achieved by means of devices in separate current paths for positive and negative AC half-cycles and by different attenuation or different transmission factors in these current paths. When the loads are switched over, the assignment of the AC half-cycle polarities to the current paths is also interchanged. <IMAGE>

Patent DE-3921813-A1 (DE)
Inventor: SODEC FRANC DR ING
IPC: F24F13/068
Filed: 1989-07-03
Abstract: An air release box has at least one perforated bottom wall section and perforated longitudinal side wall sections. At least certain of the perforated wall sections, including the perforated bottom wall section, are equipped with spin air outlets for increasing the penetration depth of low turbulence air jets into a room. Without such spin air outlets the low turbulence air jets tend to be unstable at relatively low exit velocities. The tendency of these air jets to quickly decay is thus delayed. The highly turbulent air jets exiting from said spin air outlets do not entrain air in the room, but rather they entrain inlet air coming through the perforated wall sections neighboring the spin air outlets. Thus, the jet impulse imparts a high stability to the inlet air jets.

Title: Interrupting ventilation of motor vehicle when passing foul air area - using sensor sensitive to harmful material but having sensitivity reduced when windscreen wiper operates
Inventor: RUMP HANNS
IPC: G01N27/12
Filed: 1989-09-15
Abstract: The sensor sensitive to harmful substances is exposed to the ambient air. The sensor signal is conveyed to a switch unit to interrupt the ventilation of the vehicle cabin and/or passenger space when a high level of harmful material concn. is detected.  The operating mode can be switched over to circulating air. The switching behaviour of the sensor is influenced when the windscreen wiper is operated, i.e. reduced sensitivity level. A resistor (1) in series with the sensor (2) delivers a sensor voltage (4) to a lead in proportion to the level of harmful material in the air. A calculator or regulator (3) provides a time-integrated image of the sensor signal to supply a comparator (5) also receiving the sensor voltage via a resistance matrix (6). A contact (8) is closed when the windscreen wiper is actuated. The electrical characteristics of the resistance network (6) is then changed by a resistor (7) placed into circuit, making the comparator's switching threshold less sensitive. ADVANTAGE - Avoids air being cut off under humid conditions, i.e. makes a compromise when lack of air would be uncomfortable, even if not strictly fresh.
