Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to new products of the general formula   where R1 = H,  OH,  OCOCH3,  OSO2CH3, branched or un-branched alkyl containing 1 to 5 carbon atoms.   R2 =  NHCOR3,  NHCOCH2X,  NHSO2CH3,  N(SO2CH3)2, SO2N(CH3)2,SO2NHCH3, SO2NCH3CH2CH2OH, SO2NH2 wherein R3 is a lower alkyl containing 1 to 4 carbon atoms; and X is NR4R5 or   wherein R4 and R5 are both independently lower alkyls containing 1 to 4 carbon atoms and   is piperidine, pyrrolidine or morpholine.          These products can be in the form of pharmaceutically acceptable derivatives such as esters, amides, salts.          When R2 contains an amino function, the product  can be in the form of an acid salt.          These products are prepared from their methyl esters either by reaction between   and  paramethoxycarbonylbenzoic  acid  chloride  or by means of derivative I such as R2 is NH2.         The  products  of  this  invention  are  used in therapy in the prevention and treatment of compli-cations from diabetes or as diuretics.

Abstract: ABSTRACT OF THE DISCLOSURE:         A simple, inexpensive, and effective linear actuator design comprises a motor disposed adjacent to a speed-reducer, with the driven stem of the speed-reducer passing through the rotor of the motor.  The stem has one bearing at one end of the reducer and its second bearing at the end of the motor, in a bearing part likewise serving as a bearing for the rotor.  The distance between the two bearings is increased, and the second bearing includes a socket which has a radial elasticity owing to the fact that it is monolithically joined to the fixed bearing part via a thin portion. This second bearing part is advantageously of synthetic material.  The rotation of the stem actuates a driven linear-motion part, which is prevented from rotating and which executes a translatory movement.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of obtaining an NMR image of a specimen slice in the a-b plane is provided.  The method comprises tipping the magnetization vector by an angle other than 180°.  The magnetization is then repeatedly reversed 180° so as to produce a spin echo train.  Simultaneously with the preceding steps, Ga and Gb sequences are applied in which the values of GA and Gb remain constant over each spin echo while the absolute values or preferable their actual values thereof change from  respective adjacent spin echoes, pre-ferably incrementally in co-sinusoidal relationship.  The tipping and reversing of the magnetization vector is pre-ferably accomplished by means of rf pulses.

Abstract: ABSTRACT OF THE DISCLOSURE     A case packing system, including apparatus and method, wherein cans or like products are introduced to an accumulator in a generally random single file, collected in multiple rows or lanes, and loaded into cartons or cases.          Limit means associated with the accumulator define removable abutments against which the leading cans, in the several rows, engage.  Switches are provided for sensing the presence of the completed group of cans defined by the multiple rows and, in response thereto, effecting a retraction of the limit means.  The accumulator is followed by an infeed belt which introduces the grouped multiple rows of cans into a packing station and onto a pair of support panels mounted for vertical pivoting for a downward discharge of the cans in to a subjacent case.  Empty cases are conveyed sequentially into the packing station in underlying relation to the panel supported cans.  The introduction of a single case is sensed and, in response thereto, the case is elevated to immediately underlie the support panels.  The elevation of the case triggers a release of the panels for discharge of the cans downward into the case.  The loaded case is lowered and, through operation of an underlying roller drive means, is discharged from the packing station, triggering a switch which allows for the release of a following case and a continuing of the operational sequence.

Abstract: ABSTRACT OF THE DISCLOSURE This invention is concerned with a mechanism for actuating disc brakes in motorvehicles. The mechanism comprises a caliper securely attached to the fixed main frame of the motorvehicle and carrying, on opposite sides with respect to a disc of a disc brake, a pair of friction pads which are engageable by contact with the opposed faces of the disc. The peculiar as-pect of the mechanism is that it comprises a box-like body securely attached to the cited caliper and accommodating slidably therein a push rod movable parallely to the disc axis; the push rod has at least one ramp region which engages with a first wedge having an inclined face mating in mutual sliding relationship with an inclined face of a self-adjustment wedge; the self-adjustment wedge engages at its opposite face, relatively to the first wedge, with a plunger acting on the friction pad to urge it into engagement with the brake disc.

Abstract: ABSTRACT:           In a semiconductor laser with iso-electronic dop-ing or with a quantum-well structure the efficiency is con-siderably increased by lateral injection.  For this purpose, the active region (3) is composed of active layers (4) and barrier layers (5) which are laterally bounded by semicon-ductor zones (6, 7), preferably degenerate, which inject charge carriers in the longitudinal direction of the active layers (4).  The population inversion in the active layers (4) is further increased in that superinjection occurs at the transition with the degenerate zones (6, 7).

Abstract: ABSTRACT OF THE DISCLOSURE         An adjustable time delay circuit 10, 50 includes a tine delay line 12 including a plurality of series con-nected time delay units 18a-p.  During adjustment, sampled signals along the delay line 12 are compared with a refer-ence signal by NOR-gates 22e-m.  Upon a comparison being attained  the output of the corresponding NOR-gate 22e-m sets a selected flip-flop 30e-m which in turn routes the signal at a selected delay line ta? 38e-m through a NOR-gate 34e-m to an output NAND-gate 40.   The ta? 38e-m selected compensates for component propagation characteristics thus maintaining a predetermined time delay through the time delay circuit 10.

Abstract: REAL-TIME EEG SPECTRAL ANALYZER    ABSTRACT OF THE DISCLOSURE An    electroencephelograph    (EEG)    signal analysis   system   automatically   determines   and displays, on a real-time basis, the frequency content of  spontaneous  EEG  signals  from  the  brain.   The analog EEG signals from a plurality of channels are sampled  and  converted  to  digitized  EEG  waveforms during   a   continuing   sequence   of   epochs   of predetermined  time  duration.   The  digitized  EEG waveform for  each  epoch  and  channel  is  transformed from  the  time  domain  to  the  frequency  domain  to produce a  frequency spectrum representing  amplitude of the EEG signal as a function of frequency The digital data is screened both prior and subsequent to the  transformation  to  identify  those  epochs  which contain  artifacts.   During  each  update  period,  the frequency   spectra   for   each   channel   from   the artifact-free epochs are averaged.  The amplitudes of each averaged frequency spectrum for  frequencies  in each of four basic frequency bands are then summed. The result is an amplitude value for each of the four frequency bands at each channel.  The four amplitude values are used to update a display which contains a graphical representation of the amplitude in each of the four bands in a different color.   The amplitude values  are  also  compared  with  previously  recorded base line values,  and an audible or visual warning indication  is  provided when predetermined  variances from the base line values occur.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for forming miniaturized optical components such as fiber optics connector terminals in which a three-part mold set is employed to attain precise concentricity of mold cavity formations carried by two of the three mold parts which are movable axially relative to and positioned by the third or central one of the three parts.  The two movable parts are each located by oppositely diverging frustoconical reference surfaces on the central part and include mold surface components which are axially positionable relative to the parts in which they are carried.  The central part is supported by a shuttle for movement between a molding position and an ejection position, appropriate ejection pins being Located in spaced relation to the molding position so as not to interfere with the molding operation.  Precise concentricity and axial location of the three mold parts is effected in substantial measure by application of a mold closing force exclusively along the common axis of the three parts and under a force limited to a pre-established value.
