Title: Method for operating a program-controlled controller
Inventor: DAAR HORST DR ING
IPC: G05B9/03
Filed: 1986-10-06
Abstract: For a program-controlled fail-safe controller (AG) constructed with two subsystems (AB) in a redundant manner, it is proposed to provide two identical program sequences and to carry out a mutual synchronisation of the program sequences at the beginning of particular program sections by the operating system (BS). This synchronisation can also be called up at any program points by the user program. The operating system also intersperses the individual elements of a self test into the program sequence in dependence on the instantaneous process load in order to minimise the processor load. <IMAGE>

Title: Multistage evaporator system
Inventor: WAMSER KARL DIPL ING
IPC: C02F1/08
Filed: 1987-11-10
Abstract: The invention relates to a multistage evaporator system whose evaporator stages, arranged above one another, are equipped with heating elements, especially evaporator tubes, in each of which a heating medium can be passed transversely through the evaporator stage and over whose outer surfaces the medium to be evaporated can flow downwards from the top as a liquid film, each subsequent evaporator stage being heatable by means of the vapours, produced by evaporation of part of the medium, from the previous evaporator stage. In order to provide such a multistage evaporator system according to the invention, so that the existing drawbacks no longer apply, it is proposed that, in each case, the vapour outlet (10) of one evaporator stage (1, 1'), and the vapour inlet (11) of the next evaporator stage (1', 1'') be arranged on the same side of the evaporator system. <IMAGE>
Patent DE-3738682-A1 (DE)
Inventor: ROSENTHAL KARL-HEINZ
IPC: B65D47/04
Filed: 1987-11-13
Abstract: The one-piece snap closure made of plastic for the opening of a container is provided with a sealing lever (3) above a covering plate provided with an opening, which sealing lever is articulated to a spring hinge (2) which is connected to the upper side of the closure in an articulated manner via a swivel connection (16). The sealing lever (3) and the spring hinge (2) are of approximately rectangular construction and, in the closed position, fill a diametrical incision in the upper side of the closure together with guide cylinders (7) of the swivel connections of the spring hinge (2) in such a way that the upper side of the sealing lever (3) and of the spring hinge are in alignment with the upper side of the closure. The upper side of the closure extends tangentially above two guide cylinders (7) of the sealing lever (3) which are connected eccentrically along a line (17) of the outer surface to the swivel connection (15) between the sealing lever (3) and the spring hinge (2) and engage in insertion openings, which are open upwards, in support walls on the covering plate. In the swivel direction (8), the sealing lever (3) reaches the open position (10) only after overcoming a dead centre position (9), up to which point the spring hinge (2) curves in the direction (x) until it subsequently assumes an unstressed position below the upper side (at 23a). A sturdy closure is thus provided which does not project beyond the closure edge after being opened and completely covers the mechanism so that the function of the spring hinge is not or is hardly recognisable.

Title: Manipulating device
Inventor: EMTMANN GUENTER
IPC: B66C1/62
Filed: 1987-12-09
Abstract: Known manipulating devices for transport boxes are designed as gripping gear or carrying forks or drive-in forks which necessitate lateral clearance spaces next to the stack units. Direct stacking or individual removal of a box from a plate is only possible in several steps, if need be by manual intervention. A novel manipulating device is designed as grips (10) which with a supporting arm (14) and a retaining arm (16) clasps the respective transport box (12) at its profiled edge (11) and thus permits the manipulation of the transport box (12). An additional lever transmission serves to set the gripping force as a function of load. The manipulating device is used in workshops and stores. <IMAGE>
Patent DE-3742921-A1 (DE)
Inventor: MOOSBAUER PETER
IPC: H05B41/298
Filed: 1987-12-17
Abstract: The invention relates to a ballast for a discharge lamp whose operating reliability is improved with respect to traditional ballasts, particularly in the case of ignition of the discharge lamp.   According to the invention, the ballast has a swept-frequency generator (2), connected to the DC-AC invertor (1) which varies the variable operating frequency of the invertor (1) in order to achieve reliable ignition of the discharge lamp. As a result of this self- varying operating frequency of the invertor (1), the resonant frequency of a series resonant circuit (3) which produces the ignition voltage is safely reached even when this is incorrectly tuned as a result of capacitive loads in the load circuit of the invertor. The invention can be used for the operation of discharge lamps, particularly those in vehicles. <IMAGE>

Title: Rack-and-pinion steering gear, in particular for motor vehicles
Inventor: HAEGELE GERHARD
IPC: F16H57/12
Filed: 1988-02-02
Abstract: The drive pinion mounted in the steering-gear housing and meshing with a gear rack is at risk of fracturing particularly when highly stressed in a shock-like manner. The intention is therefore to increase the stressability of steering gears of this type. A support shell (11) is installed in the steering gear housing above the drive pinion (1). The support shell (11) can be riveted, bolted or adhesively bonded to the steering-gear housing (4). It fits around the drive pinion (1) at an angle of approximately 180 degrees. The support shell can also be cast integrally with the steering-gear housing (4) as a projection. When sharp, shock-like stresses occur the drive pinion (1) is deflected and then bears against the support shell (11). In this manner fracturing of the drive pinion (1) can be avoided. <IMAGE>
