Abstract: The trajectory of a projectile is variable by means of a thrust generated by gas issuing from a nozzle (13, 14), the nozzle normally rotating at high speed about the axis of the projectile but assuming a desired angular orientation for a predetermined period of time in order to impart a lateral thrust to the projectile thereby changing its trajectory.

Abstract: A method for determining the presence of an analyte in a fluid is described along with an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface (15) of an inert porous matrix (11) impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analysed is applied to another surface (16) and migrates through the matrix to the surface being read. Reflectance measurements are made at two separate wavelengths in order to eliminate interferences, and a timing circuit is triggered by an initial decrease in reflectance by the wetting of the surface whose reflectance is being measured by the fluid which passes through the inert matrix. The method and apparatus are particularly suitable for the measurement of glucose levels in blood without requiring separation of red blood cells from serum or plasma.

Abstract: A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.

Abstract: The device which is particularly suitable for concrete dry injections is provided with a dry concrete mixture inlet and a water supply arranged around the latter. A water nozzle ring (12) on which water passages (28) which extend preferably evenly over the annular circumference and essentially radially and are inclined with respect to the annular longitudinal axis are arranged, serves for constantly changing the overall nozzle cross-section (28) for the water directly before it joins the concrete mixture. In this device, the amount of water is controlled by changing the nozzle cross-section directly before the water outlet itself with an essentially constant nozzle jet speed. For this purpose, a hydraulic, manually actuated adjustment device which is very easy to handle and operates on a displacement basis is used. <IMAGE>

Abstract: The arrangement is used to control the dynamic range of speech signals in a telecommunication terminal, e.g. in a videophone unit with a hands-free facility. In a hands-free unit, the signal-to-noise ratio is lower than in a telephone with a handset. In order to prevent feedback singing, the known hands-free unit has a dynamic range control, with which, when amplification in the transmitting path is increased or reduced, the amplification in the receiving path is reduced or increased by the same amount. The object is to make use of the maximum possible loop gain without reducing the amplification in the receiving path. This is achieved by connecting after the microphone (50) a controllable volume compander (52), in which the signal voltages supplied from the microphone (50) are A. compressed if they are above a pre-defined signal level, B. expanded if they are below the pre-defined signal level, and C. amplified to the maximum extent if they match the pre-defined signal level. This level, which corresponds to the compression implementation point, is set by means of a control circuit (90) depending on ambient noise.

Abstract: For the reactive deposition of tubular metal bodies, for example self-supporting glow cathodes as well as layers and mouldings for high-temperature applications, from a flowing gas phase (18) containing a metal halide on a tubular substrate, a glow discharge (13) is generated between an inner electrode (7) and an outer electrode (3), one of which is of tubular structure and serves as the substrate. A high metal deposition yield is obtained by carrying out the reactive deposition from the gas phase in the region of high plasma resistance. In a preferred measure for setting the high plasma resistance, the absolute mass flow of the metal halide is adjusted to at least 60 sccm. …<IMAGE>…

Abstract: The invention provides an improved vibration isolator (10) for use, for example, in an automotive engine mounting. The vibration isolator has a hollow outer cylinder (14) and an inner cylinder (12) disposed in and parallel to the outer cylinder. One of the two cylinders is to be connected with a member that vibrates and the other with another member to be isolated from vibration. An elastic body (20) tightly interposed between the outer and inner cylinders is formed with a hollow (22) so that tensile force may not act on this body. Opposite to the hollow with respect to the inner cylinder the elastic body is formed with radially inner and outer liquid chambers (26A, 26B) which are connected to each other by a flow restrictive passage (32). An elastic membrane (16) is attached to the inner surface of the outer cylinder, and a part of the membrane serves as a flexible diaphragm defining the radially outer periphery of the outer liquid chamber. In a region where the elastic membrane is used as the diaphragm, the cylindrical wall of the outer cylinder is formed with an opening to expose the diaphragm to the atmosphere. This vibration isolator can easily and accurately be assembled in the liquid to be filled into the liquid chambers without need of any extra operation for extracting the liquid from any other space or chamber in the assembled device.

Abstract: A laser beam from a laser source (1) is incident on a track (8) of an optical card (7) through an objective lens (3). Since the optical card (7) is reciprocated along a track direction, the laser beam is scanned on the track (8). The light beam reflected by the optical card (7) is guided to a photo-detector (6) through the objective lens (3) and a mirror (5). An objective lens actuator (2) and an objective lens position sensor (4) are arranged near the objective lens (3). The objective lens actuator (2) performs tracking of the laser beam by moving the objective lens (3) in a direction perpen­dicular to the track (8), and focuses the objective lens (3) by moving it in a direction perpendicular to the optical card (7). The lens position sensor (4) detects the displacement of the lens (3) during tracking. A track-error signal generated from the photo-detector (6) is supplied to the actuator (2) through a phase compen­sate circuit (23) and a power amplifier (24), thus performing tracking servo control. An output from the lens position sensor (4) is supplied to an off-track detector (25). The off-track detector (25) is consti­tuted by a low-pass filter (51) for cutting a high-­frequency component, such as noise, a DC-cut circuit (52), and a window comparator (53).

Thus, the width of each facet (134) is no greater than is necessary to perform its function and is less than a prior art facet performing the same function.

Abstract: The invention relates to a method of suppressing amplitude variations of two electrical signals (uS1, uS2) in phase quadrature and a circuit arrangement for carrying out the method. According to the invention, the positive or negative amplitude variation of the signals (uS1, uS2) is monitored for undershooting of a lower or overshooting of an upper reference voltage (+/-US- or +/-US+) in such a way that in the event of undershooting or overshooting a device (20, 22) for changing a prescribed manipulated variable of an actuator (8, 10) is activated, and the signals (uS1, uS2) are respectively converted into rectangular signals (uRS1,uRS2), from which clock pulses (uC11 or uC12) are generated by means of a logic circuit (24 or 26) depending upon the phase sequence of the signals (uS1, uS2) at the positive or negative flanks of the rectangular signals (uRS1, uRS2), which vary the prescribed gain as a function of the result of the amplitude monitoring by a prescribed value (LSB). This yields a method of suppressing amplitude variations of two electrical alternating, periodic signals (uS1, uS2) in phase quadrature with a random phase sequence, and a circuit arrangement for carrying out the method that operates independently of frequency.   <IMAGE>
