Abstract: A non-intrusive tachometer for measuring engine RPM includes a hand-held probe (26) having an antenna (38) for sensing radio frequency electromagnetic signals radiated from an operative spark ignition engine. The probe (26) includes means for providing a pulse signal indicative of plug firing events to signal processing means (106,14) which executes a statistical algorithm to determine the time between spark plug firings and engine RPM. A visual display (16) displays engine RPM. Automatic gain control means (132,134) provides the pulse signal with a relatively constant amplitude by compensating for the inherently wide variation in amplitude of the electromagnetic signals among different automobile ignition systems. The signal processing means (14) and display (16) are located separate from the probe (26) in an emissions testing system (10) or the signal processing means (316) and display (460) are integrated within the probe (450).

Abstract: Procedure and apparatus for braking a squirrel-cage elevator motor (1) fed by a frequency converter (10) in fault situations using a direct current supplied from a d.c. voltage source (11). In the procedure, the current in at least one of the motor phases and the rotational speed of the motor are measured, and the supply of direct current is controlled by means of a switching device (K1). When the elevator speed exceeds the value corresponding to the nominal slip and the motor current is less than the nominal magnetizing current, the switching device (K1) is caused to connect a direct current from the d.c. voltage source (11) to the motor.

Abstract: In a mobile disinfection installation, which is mounted on a support structure (1), for hospital waste, an obliquely rising worm conveyor (4) starts from the foot of a charging shaft (3) in which a cutting mechanism (17) is located and opens into a rotational pipe (5) equipped with lifting shovels (43). A closed discharge housing (6) with a discharge device (49 to 52) for the disinfected waste and a suction pipe (53) for the treatment medium is arranged at the discharge end of the rotational pipe (5). 
<??>The actual disinfection takes place in the rotational pipe (5) which has a large cross-section in comparison with the worm conveyor (4). As a result, a large throughput can be achieved under the restricted spatial conditions of a mobile installation. The rising worm conveyor (4) spans as an intermediate conveyor the height difference between the foot of the charging shaft (3) and the charging opening of the rotational pipe (5). In this way, it permits the charging shaft (3), which takes up virtually the entire height which is permissible for road transport, to be combined with the rotational pipe (5) whose charging opening is unavoidably located at a certain height above the floor due to the relatively large diameter and in view of the material discharge located at the end of the rotational pipe.

Abstract: A drive circuit (13) for use with a capacitive load (10) includes two transistors (18, 20) controlled by a drive voltage (22) and connected to the load (10) through an inductor (14). A supply voltage (16) is alternately connected and disconnected to the circuit (13) to achieve a resonant transfer of energy from the supply voltage (16). Energy stored in the load (10) is transferred to the inductor (14) and then back to the load (10), thereby reversing and augmenting the output voltage across the load (10) and providing an instantaneous output voltage many times the supply voltage. Diodes (24, 26) ensure that the current flows in the proper polarity through the transistors (18, 20). The output voltage across the load (10) is controlled by energy limiting means (30 - 44).

Abstract: The transducer for surface plasmon resonance has a support made of gold on whose surface a two-dimensional matrix is produced in the form of a monomolecular organic interlayer and of a ligand or antiligand layer immobilised thereon. Compared with known transducers with a three-dimensional matrix, the transducer according to the invention can be produced considerably more straightforwardly. For production, a monomolecular layer of alkyl derivatives with sulphur-containing groups is applied to the gold surface by spontaneous chemisorption and subsequently a ligand or antiligand suitable for the required immunological test is immobilised on this layer.

Abstract: An optical amplifier and photodetector are monolithically integrated, with the photodetector being optically coupled to the optical amplifier through a low radiative loss and low back reflectivity branching waveguide. Because of the low reflectivity, the branching waveguide, although having a truncated wedge tip, is able to redirect a small portion of optical radiation from the amplifier to the photodetector without deleteriously effecting the performance of the optical amplifier. The branching waveguide is realized by employing between the branches of the waveguide, a junction region having a gradual decrease in effective refractive index such as to decrease the difference between the refractive indices at the optical interface of the truncated wedge tip as seen by optical radiation incident thereto from the optical amplifier.

Abstract: Pulse echo apparatus and methods are disclosed for measuring characteristics of a borehole while it is being drilled. A component of a bottomhole assembly, preferably a drilling collar , is provided with one or more ultra-sonic transceivers. A pulse echo sensor of the transceiver is preferably placed in a stabilizer fin of the collar, but may also be placed in the wall of the collar, preferably close to a stabilizing fin. Electronic processing and control circuitry for the pulse-echo sensor is provided in an electronic module placed within such collar. Such pulse echo apparatus, which preferably includes two diametrically opposed transceivers, generates signals from which standoff from a borehole wall may be determined. A method and apparatus are provided for measuring standoff and borehole diameter in the presence of drilling cuttings entrained in the drilling fluid. In a preferred embodiment, such signals are assessed by the electronic processing and control circuitry to determine if gas has entered borehole. Three methods and apparatus are provided for such gas entry determination. The first relies on measurement of sonic impedance of the drilling fluid by assessing the amplitude of an echo from an interface between the drilling fluid and a delay-line placed outwardly of a ceramic sensor. The second relies on measurement of drilling fluid attenuation of a borehole wall echo. The third relies on measurement of the phase of oscillations of echoes to identify large gas bubble entries. The pulse-echo sensor includes a sensor stack including a backing element, a piezo-electric ceramic disk, and a delay-line.
