Abstract: Abstract. Process for the preparation of a unit for the determination of residues of antibiotics and sulphas in biological liquids, the unit thus prepared and process for carrying out the determination. Spores of a microorganism showing a broad sensitivity for the antibiotics and sulphas to be tested are introduced into an agar solution so that they cannot germinate but stay alive, while by addition of a small amount of tri-methoprim the sensitivity for sulphas is increased, whereafter the agar solution is allowed to solidify in tubes of prefer-ably transparent material. The unit is very useful for the determination of residues of antibiotics and sulphas in, e.g. milk by less skilled persons.

Abstract: TREATER WITH SELF-CLEANING ELECTRODES              Abstract Of The Disclosure The treater employs a pair of closely spaced, superimposed circular electrode plates, and the liquid to be treated is passed through the limited area between such plates in a pressurized sheet such that the liquid tends to clean the electrodes at the same time as it receives treatment thereby. An annular groove adjacent the discharge periphery of the lower plate has the effect of causing the discharging sheet to assume an umbrella-like configuration to promote aeration of the discharging liquid.  If desired, the plates may be associated with a receptacle in such a way that the umbrella-like discharging sheet engages the walls of the receptacle at one electrical polarity while at least one of the electrode plates is of the opposite electrical polarity so as to promote effective treatment.  On the other hand, if desired, the plates may be submerged within such a receptacle adjacent the sludge collecting at the bottom thereof.  In one embodiment the opposed plates are of the same electrical polarity while another electrode situated upstream from the plates is oppositely charged.      (Docket 16596)

Abstract: ABSTRACT               APPARATUS FOR MEASURING THE               AXIAL LENGTH OF AN EYE           An apparatus for measuring the axial length of the eye is disclosed.  The apparatus comprises a transducer adapted to transmit repetitive ultrasonic pulses along the ocular axis of the eye of a patient and to receive echo pulses reflected from the retina of the eye.  A fixed gain amplifier is connected to a transducer for amplifying the reflected echo pulses.  An automatic gain controlled ampli-fier is also connected to the transducer for amplifying the reflected echo pulses.  Control means are coupled to the automatic gain controlled amplifier for gradually increasing the gain of the amplifier to a predetermined maximum gain.          First and second gate circuits are coupled to the output of the fixed and automatic gain controlled amplifier, respecti-vely, and adapted to pass logic signals triggered by retinal echo pulses exceeding first and second predetermined thre-sholds.  A digital counter is connected to the second gate circuit and adapted to display the axial length of the eye as a function of the distance travelled by the retinal echo pulses.  A gate width generator is connected to the second gate circuit for generating a time slot during which echo pulses originating from the posterior wall of the eye can be received.  A retinal echo triggered gate width generator is connected between the first and second gate circuits and is responsive to the first gate circuit for enabling the se-cond gate circuit to pass logic signals triggered by retinal echo pulses exceeding the second threshold in the time slot generated by the gate width generator.  The output of the retinal echo triggered gate width generator is also connec-ted to a latching circuit which is connected to the first gate circuit for blocking the first gate circuit immediately after receipt of the first logic signal triggered by a reti-nal echo pulse, thereby preventing mistriggering of the re-tinal echo triggered gate width generator circuit by echoes originating from structures behind the retina.

Abstract: ABSTRACT:        "X-ray powder diffractometer".     A computer controlled asymmetric texture-sensitive parafocussing X-ray powder diffractometer employs an incremental rotating specimen holder for azimuthal ro-tation  through an angle ?. The specimen holder is rotatable through an angle ? from a symmetric position in which the specimen surface normal makes an angle (90 - ?)° with both the source-to-specimen and detector-to-specimen directions. In order to maintain the Brentano focussing condition, the detector is supported on a slide which can be moved towards and away from the specimen by a stepper-motor drive. A ratio K of the detector-to-specimen distance R on the one hand and the X-ray source-to-specimen distance P on the other hand is constrained to a range c < K > f. The desired focussing condition is realized by computer control which maintains K = sin (?+?)/sin (? - ? ) and modifies the measured value of the intensity by multiplying it by 0.5(K + l) K0.75exp [/UR (K - 1)] where  /u is the linear absorption coeffi-cient for air.

Abstract: ABSTRACT OF THE DISCLOSURE     Composite panelling of upper and lower metal skins with side configuration for interlocking and a rigid foam core are continuously made by feeding separate upper and lower skin panels secured together by preassembled rigid foam end dams continuously past a foam station having a small height mixing head mounted on cross slides to lay down a zigzag pattern of foam between the skins, with the first and last transverse run of foam being parallel to the ends of the skins.  A mixing head is such that valves are located within the head so that the two foamable chemicals do not contact each other until they are fed into the mixing chamber wherein a mechanical mixer mixes them immediately prior to being deposited, which mechanical mixer and valves are of minimum height and fully insertable within the molding space between the skins.  A drive motor for the mixer is located in the main body supporting the mixing head, which main body does not enter into the mold cavity.  The valves and cross slide are operated auto-matically, and if there is too long a delay between foam deposits, the chemical valve faces, mixing chamber, mechanical mixer and other parts exposed to the mixed chemicals will automatically be flushed with a solvent and air.
