Abstract: The journal (6), which projects from the outer surface of the cup element (2) at an angle of 45 DEG , is surrounded by a sleeve (7) which is closed off in the manner of a cap at the free end. 
<??>First, this sleeve forms with the journal (6) a cylindrical rolling bearing (10), which makes it easier to swing the cup element (2) into the correct position in the pelvic bone (1); second, the sleeve (7), which generally consists of metal, prevents direct contact between the preferably plastic journal (6) and the bone (1).

Inventor: GROS HENRI DR
IPC: C02F3/28
Filed: 1989-05-31
Abstract: In a plant with a central heat exchanger (4) which can be connected on its primary side (8) to a disinfecting and at least one treatment tank (11 and 19 respectively), fresh sludge which is to be treated is preheated in two stages at intervals (T) batchwise by heat recovery with treated sludge. This entails mutual phase-shifted replacement in a known manner of heat-delivering, treated sludge and heat-receiving, cold fresh sludge in the central heat exchanger (4). While observing a minimum interval (H), the time within an interval for replacement of a cold fresh sludge batch is shifted in order to set the temperatures of sludges fed from an aerobic digestion to preset values. This optimises the heat recovery and, for example, minimises the input of outside energy and prevents losses due to outside cooling of the disinfected sludge. <IMAGE>

Abstract: The control device for a combustion engine, especially a diesel engine (1), with a power transmission (7) to a drive (9), the transmission ratio of which can be altered, has a proportional-action controller (4) with a revolution counter (2), an actuator (3) for adjusting the fuel injection quantity and a controller (4) with an adjustable speed set point, and a monitoring and adjusting arrangement (5). The speed set point (n) of the engine (1) in the case of different torques is readjusted by the proportional-action controller (4) along a straight portion of the control characteristic predetermined by the speed set point. If the proportional-action controller (4) leaves a torque/speed set point range of the engine (1) stored in a read-only memory (31), the monitoring and adjusting arrangement (5) alters the set point of the proportional-action controller (4) and, if need be, the transmission characteristic of the power transmission (7) in such a way that the proportional-action controller (4) operates within the range again. <IMAGE>

Title: Scanning electron microscope.
Inventor: STELLMANN KARL HEINZ
IPC: H01J37/28
Filed: 1989-01-17
Abstract: The images produced by conventional scanning electron microscopes, in which a goniometer arrangement serves as a specimen support, are subject to losses of resolution in the case of large, heavy specimens. These losses are traceable to vibrations of the ground which induce vibrations in the spring/mass system formed by the goniometer on the one hand and the specimen on the other hand. These vibrations are produced relative to the electron beam of the optoelectronic system and the specimen. To eliminate these losses of resolution, the goniometer is designed as a mounting for the optoelectronic system and the detectors, while the specimen support is designed as a rigid, stationary specimen stage. The resonance frequencies of the spring/mass system are thereby shifted into a range in which no excitation due to ground vibrations can occur. In addition, the mobility of the optoelectronic system and of the detectors permits greater mobility inside the specimen chamber.

Abstract: A residual winding (10) is sucked off from a bobbin (7), mounted on rotatable rollers, by means of a suction nozzle. According to the invention, to prepare for the suction of the residual winding (10), a piece (11) of the latter is detached by pressing a brush (9) having elastic bristles against the residual winding (10) along a generatrix of the bobbin (7), whilst the bobbin (7) is rotated through approximately two revolutions in the unwinding direction by means of a ram (5). Subsequently, a needle comb (12) is pushed through a slotted bar (14) into the brush (9), and the brush and needle comb are lowered. The brush (9) is lowered further and pulled through the needle comb (12) which is itself retracted through the slotted bar (14). Both are thus cleared of fibres which are removed by means of a suction funnel (15). Instead of the brush, it is also possible to use a slit nozzle which generates a compressed-gas flow directed obliquely against the surface of the bobbin (7) opposite to the direction of rotation of the latter. <IMAGE>

Abstract: A system for comfortably concentrating in individual stalls a group of elongated four-legged animals which as a group have generally the same length and breadth, particularly, gestating sows. The system comprises at least one row of stalls (A-O; A′-O′) or compartments arranged side-by-side. Each adjoining pair of the stalls share a common vertical divider (10) or partition one end (11) of which is stationary or fixed with the remainder (12) being pivotally attached (13) so as to be swingable from side to side. Preferably, the extent of swinging is limited by a length of chain (44). The width of each stall measured between adjacent stationary ends of the dividers is sufficient to comfortably accommodate the breadth of the animals either standing or lying but insufficient to accommodate their lengths. The length of each stall is sufficient to comfortably accommodate the lengths of the animals either standing or lying. The widened space formed between the swingable divider portions (12) of a stall on being forced apart by an occupying animal is sufficient to allow the animal to turn around in its stall.

Abstract: In an apparatus for forming micro-haloes on a cigarette (c), a laser beam (L) is divided into first and second laser beams (La, Lb) by a two-dividing mirror (101). Parts of the laser beams (La, Lb) are detected by photo detectors (110, 111), respectively and the other parts of the laser beams (La, Lb) are guided to polyhedron mirrors (103, 107) through first and second optical paths and divided into segment beams by the mirrors (103, 107), respectively. The segment beams are focused on the corresponding cigarette (c) so that micro-hales are formed on the cigarette (c). The cigarette (c) is transferred to a dilution detection stage and the dilution is detected in the dilution detection stage. In an initial driving mode, detection signals from the photodetector (110, 111) are processed and a first driving signal is generated. Thus, the two-dividing mirror (101) is driver by a driving mechanism in accordance with the first driving signal so that the intensity of the laser beams (La, Lb) guided in the first and second optical paths are maintained in substantially equal level. In an stable driving mode, a second driving signal which is determined in accordance with the detected dilution is applied to the driving mechanism in stead of the first driving signal so that the two-dividing mirror (101) is driven in accordance with the second driving signal.

Abstract: A device for deterring theft of a protected article, including a pin (14) and clutch (16) for attaching the device to the article, with the pin and clutch being embodied in two components (10, 12) that are adapted to be locked together on opposite sides of a portion of the protected article to prevent unauthorized removal of the device from the article. The pin has a head (40) that is anchored within one component (10); and the clutch in the other component (12) grasps the pin to provide a predetermined retaining force for resisting separation of the com­ponents by prying or pulling the components apart. The one component (10) in­cludes three fragile elongated vials (20) that fracture when at least a predeter­mined pressure is applied thereto, with each vial containing a detrimental sub­stance (22) that would damage the article if the vial were to be fractured while the device was attached to the article; and the one component (10) defines a head space (25) for enabling limited axial movement of the pinhead (40), and three guide channels (27) respectively containing three balls (29) between the pinhead and the vials. Flexible cradles (34) shield the vials from contact with the balls during a relaxed state, but yield to enable the balls to contact the vials when the balls are moved in response to the pinhead being moved in response to application to the two components of at least said predetermined threshold separation force.
