Abstract: A new class of methods for characterizing particles is described along with associated apparatuses. These methods are called modulated dynamic light scattering (MDLS) methods because they utilize time and space modulations of the incident or scattered light as well as modulations caused by random Brownian motions of the particles, for example, to measure particular properties. The autocorrelation function of the scattered light signal from a particle is measured to provide a highly resolved signature even when the signal is buried in noise. The dynamics of the scattered light signal from a suspended particle undergoing random Brownian translations and rotations is analyzed to obtain the relationship of the particle's properties to its autocorrelation function signature. By comparison of the theoretical and measured functions, properties of a particle suspended in a liquid, gas, or rarefied gas can be determined. The general shape category, velocity, translational friction coefficient and the mass of the particle are determined. The particle charge and charge-to-mass ratio can also be determined.

Abstract: A liquid-crystal cell whose filling opening is located in a corner of the cell is immersed in liquid-crystal material inside a vacuum vessel after evacuation and is immediately drawn up once again, as a result of which a drop of liquid-crystal material is formed at the filling opening. Subsequently, the vacuum vessel is rapidly aerated, and the cell is filled outside the vacuum vessel. The volume of the drop and the volume of the cell are to be matched to one another so that the drop volume is at least as large as the volume of the cell interior, in order to enable filling to be performed with the aid of the drop volume alone. 
<??>Owing to the fact that the filling is performed merely by briefly lowering the liquid-crystal cell and raising it once again, and then holding it with the filling opening downwards until the volume of the drop, which has been formed during lowering into the liquid-crystal material and while being drawn up once again, has been completely sucked in, the method is extremely simple in terms of equipment outlay and sequence of operations, as well as reliable. A further advantage is that the vacuum vessel is occupied only for the shortest possible time.

Abstract: Axial magnetic bearings are described suitable for use where high loads and high rotational speeds are found together. In an axial magnetic bearing, for thrusts along the shaft (31) in one direction, there are included, in relation to the shaft (31), a generally radially extending thrust accepting face (38,43); and an electromagnet (37), with a face of each pole (36) thereof parallel to, but spaced from, an individually associated portion of the thrust face (38,43). The rotor disc (32) is tapered in the radially outward direction, to reduce the mass of the disc (32). Thus, the two said portions of the thrust face (38,43) are radially separated, and are separated from each other along the axis of the shaft (31). Possibly, the two said portions of the thrust face (38,43) extend precisely radially, between the portions there being a part of the thrust face (38,43) in the shape of a truncated cone.

Abstract: An automatic high pressure, frictionless, water and chemical vehicle washing device (10) is self-contained and has a light weight aluminum frame which (20,21,23,24,25,27,16) can be attached to a floor by adjustable leg supports (22,26) or suspended from a ceiling, allowing it to be installed easily and quickly into any self-service or automatic car wash bay. The device is powered by relatively low air pressure and the spray washing head (32,34) is movable in perpendicular directions allowing the spray head (32,34) to seek any possible location within the boundaries of the machine itself. Photo-electric infra-red beams (54,(56)57)58) sense the presence of the vehicle (V) being washed; relay signals to a programmable controller, and direct the spray head (32,34) to seek the dimensions of various sized vehicles. Once the vehicle (V) dimensions are established via communication between the photo-eye and the programmable controller, the machine maintains a safe but effective washing distance between the spray head (32,34) nd the vehicle surface of approximately fourteen inches. A mechanism is provided for indexing the spray head (32,34) which causes it to rotate precisely ninety degrees at each corner of the vehicle and then lock in place by the force of a single small hydraulic cylinder activated brake.

Abstract: Second-order gradient directional microphones, both toroidal and unidirectional, derived using a first-order gradient sensor and an acoustically reflecting surface are disclosed. The sensor is positioned with its axis illustratively orthogonal to and suspended a few centimeters from a large acoustically reflecting surface. The resulting sensor image is phase reversed resulting in a transducer that is a linear quadrupole. The linear quadrupole can be described by two dimensions; the distance corresponding to the sensor's dipole distance and twice the distance from the reflecting plane. If the reflecting surface is large enough or if the wall of an enclosure is used, the resulting microphone becomes a second-order gradient unidirectional microphone. A perfect match between the sensor and its image from a good acoustic reflector results in an ideal second-order gradient microphone with 3 dB beam width of ±33 and no grating lobes below about 3 kHz for a spacing from the reflecting plane of about 2.5 cm. Toroidal directional microphones are formed using two or more sensors and an acoustically reflecting surface.
