Title: Method and device for checking cigarettes
Inventor: FOCKE HEINZ

Filed: 1988-11-02
Abstract: In the checking of cigarettes (10, 11) of cigarette groups (16, 17) in pockets (13, 14) of a conveyor, in particular of a cigarette revolver (12), difficulties arise in respect of the adequate spacing of checking elements (29..32) from one another when the cigarettes (10, 11) have a particularly small diameter. In order nevertheless to permit undisturbed checking by moving the checking elements (29..32) up to the front ends of the cigarettes (10, 11), the latter are checked successively in several, in particular two, steps, the checking elements (29..32) checking during each of these checking cycles cigarettes which are at a relatively large distance from one another. In particular, only every second cigarette within rows (18..21) of the cigarettes is checked.

Abstract: The watering valve (10) has, on the valve stem (13), an actuating end (27) which projects downwards relative to the housing (15) and by means of which the animals can open the drinking valve (10) merely by tipping the valve stem (13), needing only to move laterally against the actuating end (27) in order to do so. Moreover, a sealing seat is of exclusively metal design, as a result of which a circumferential rounding in the housing (15) corresponds to a frustoconical transition (30), in particular on the valve stem (13). The drinking valve (10) is particularly suitable for use in large-scale chicken breeding, where it can easily be actuated even by chicks because of its special design. <IMAGE>

Abstract: A bidirectional semiconductor switch is produced in a semi­conductor layer (2) (e.g. silicon) arranged on an insulating base (1) of e.g. sapphire. The switch has two highly doped main contact regions (3a, 3b). Between these regions the switch has a voltage absorbing part comprising a weakly doped layer (5), located next to the surface of the semicon­ductor layer, of the same conductivity type as the main con­tact regions, and a weakly doped layer (4), located next to the base, of the opposite conductivity type. Between each one of the contact regions (3a, 3b) and the weakly doped layer (5) located near the surface, normally non-conducting MOS structures (6a, 8a, 6b, 8b) are arranged. By simultane­ously controlling the two MOS structures to conducting state, the switch becomes conducting and is able to carry current in an optional direction between the main contacts.

Abstract: A two-stage aqueous slurry chlorination process which employs a constant gaseous chlorine flow rate and a temperature which increases from an initial chlorination temperature of 100°C to a line-out chlorination temperature of from 116° to 128°C in the first stage and remains at the line-out temperature in the second stage. The process produces CPE resins having a chlorine content of from 43 to 55 %bw of polymer. Polymer blends of such CPE resins with PVC resins provide impact strength improvements in comparison to the PVC resin alone and transparency which approaches or equals that of unmodified PVC resins.

Abstract: A device is proposed for the pneumatic braking of a commercial vehicle provided with a brakable trailing axle which can be lowered as a function of load. Compared to known solutions, which employ automatically acting load-dependent brake pressure regulators for the rear axle/s in conjunction with a service brake valve controllable directly by the regulated rear-axle brake pressure, the device according to the invention provides the connection of a pressure- reducing valve (23) into the corresponding control path between brake pressure regulator (19) and service brake valve (14). This connection occurs automatically, in accordance with the vehicle loading and number of load axles, as a function of the sensed pneumatic pressure in the lifting bellows (26) of the trailing axle. This results in a better braking behaviour and a higher specific utilizability overall of the brakes, with the trailing axle alternatively lowered or not lowered. <IMAGE>

Abstract: In apparatus for radiographic diagnostics an X-ray beam attenuated by an object to be examined is converted into a light image by means of an X-ray image intensifier tube.  Inter alia  as a result of the geometry of the X-ray beam and of the input screen of the X-ray image intensifier tube the intensity of the image decreases towards the edge (vignetting). By arranging a stray radiation grid, for example, in the form of a perforated plate of X-ray-absorbing material, for example, lead or tungsten, in the path of radiation between the X-ray source and the X-ray image intensifier tube, vignetting can be reduced by an adapted variation of the local transmission of the stray radiation grid.

Abstract: An actuating system is described for a phase change mechanism wherein the phase change mechanism comprises a rotatable phase change assembly and an actuator which rotates at the same speed as the assembly when the phase between a drive and a driven member is to be maintained constant and which is required to rotate relative to the phase change assembly to bring about a change in phase. 
     The actuating system comprises reaction members 50, 52 coupled to the actuator 26 and braking means 54, 56 associated with the reaction members 50, 52. The reaction member when not braked is free to rotate with the phase change mechanism, but when braked each serves to vary the speed of the actuator 26 relative to speed of the phase change mechanism in a different sense.
