Abstract: A resonant scanning unit utilizes a "tuning fork" design with a mirror (30) mounted on one arm of the tuning fork and a counterbalance mass (40) mounted on the other arm. A voice coil electromagnetic motor (44, 46) mounted between the arms causes the arms to move in opposite directions. Light generated by a line of LEDs is reflected from the oscillating mirror (30) to generate a raster display. Reaction forces generated by the motions of the mirror (30) and counterbalance mass (40) cancel at the device base (21), reducing vibration. In addition, the inventive structure allows placement of the mirror pivot point away from the center of the mirror which allows display devices constructed with the structure to be reduced in size.

Abstract: 2-(difluoromethoxy)-1,2,2,2-tetrafluoroethane (CHF₂OCHFCF₃), a known inhalation anaesthetic, is prepared by a synthetic route in which a first and novel intermediate: 
p-CH₃C₆H₄CHF₂OCHFCF₃ 
is prepared by reacting methyl hemiacetal (CF₃CH(OH)OCH₃) with para-toluene sulphonyl chloride in the presence of an organic base such as triethylamine at room temperature. The resulting novel tosylate intermediate is then converted to a second intermediate CF₃CHFOCH₃ by reaction at elevated temperature with a fluorinating agent such as caesium fluoride. The second intermediate is converted by known means to CHF₂OCHFCF₃ (eg by photochemical chlorination) followed by fluorination of the resulting compound with HF in the presence of SbCl₅.

Abstract: A magnetic resonance imaging system collects all the data required for image reconstruction of a prede­termined portion of an object (5) under examination by one excitation process in accordance with a pulse sequence in which, after excitation of spins within the predetermined portion by a radio frequency magnetic field and a gradient magnetic field, a predetermined readout gradient magnetic field is applied switched positive and negative at high speed to produce multi­echoes on both sides of a spin echo center and a prede­termined phase encoding gradient magnetic field is applied whose amount and sequence in encode steps are controlled so that multiecho data or its complex conju­gate data may scan substantially the half of a Fourier data plane. By taking the complex conjugate of the magnetic resonance data collected in that way and then two-dimensional Fourier transforming the magnetic reso­nance data and the complex conjugate data, a magnetic resonance image of the predetermined portion of the object (5) is obtained.

Abstract: The invention relates to an unwinding reel, which can be mounted rotatably on a rotary table, for coils, in particular for coils of wire, with a coil support arrangement which is held by a stand and on which the coil to be worked off in a vertical direction can be placed from above, which has at least one essentially horizontal support surface and a number of essentially vertically aligned support parts standing at uniform angular distance from one another, which, to centre the coil, are displaceable radially outwards against the force of a return device, under the action of the weight force of the coil on the support surface, and with a fixing device for the coil support arrangement. In order to be able to carry out considerably more economically the working of wire, cables or the like, which are available in the form of coils wound without spools, the invention proposes that the unwinding reel is in operation mounted removably on a centring pin assigned to the rotary table and that the fixing device is designed as a variable locking device of the radial displaceability of the support parts. <IMAGE>

Abstract: A circuit arrangement reduces the time necessary for a voltage-to-frequency converter to provide a new output frequency in response to a change in input voltage levels. A current source (34) provides additional input current to the input integrating node of the v/f (22) before a conversion is requested. When a conversion is requested, the additional input current effectively provides operation of the v/f (22) at an increased frequency, thus speeding the settling process therefor. When the integrator of the v/f is at a predetermined voltage level in a predetermined operating cycle, the current source is removed, thus terminating the increased frequency of operation.

Abstract: The present invention relates to a method for producing, by means of working, mixing and homogenizing, castable explosive substances of high viscosity containing crystalline and/or particulate explosives and, if appropriate, other action-enhancing additives and such small quantities of binder and other viscosity-reducing agents that the mixture in the unworked state virtually feels like and behaves like a dry powder. In order to achieve the desired working, mixing and homogenizing, the components are brought to the roll nip between two helically grooved rolls, which form part of a so-called mixing, sheaving and rolling mill. The rolls are arranged at an adjustable distance from each other and counter-rotating at different speeds. The mixture is worked on and between the rolls until the air between the particles included has been pressed out sufficiently to convert the previously pulverulent mixture to a coherent mass of high viscosity. The material is removed from the fastest rotating roll in continuous form or in a newly formed particulate form associated therewith.
