Abstract: Lightly crosslinked polymers, preferably ones prepared by suspension or emulsion polymerizing at least about 90 % by weight of a carboxyl-containing monoethylenically unsaturated monomer such as acrylic acid with from about 0.1 % to about 5 % by weight of a polyfunctional, and preferably difunctional, crosslinking agent such as divinyl glycol (3,4-dihydroxy-1,5-hexadiene), having a particle size of not more than about 50  mu m in equivalent spherical diameter, when formulated with an ophthalmic medicament, e.g., fluorometholone, into suspensions in aqueous medium in which the amount of polymer ranges from about 0.1 % to about 6.5 % by weight, based on the total weight of the aqueous suspension, the pH is from about 3.0 to about 6.5, and the osmotic pressure (osmolality or tonicity) is from about 10 mOsM to about 400 mOsM, provide new topical ophthalmic medicament delivery systems having suitably low viscosities which permit them to be easily administered to the eye in drop form, and hence be comfortably administrable in consistent, accurate dosages. These suspensions will rapidly gel in the eye after coming into contact with the eye's tear fluid to a substantially greater viscosity than that of the originally-introduced suspension and thus remain in place for prolonged periods of time to provide sustained release of the ophthalmic medicament.

Abstract: In such a circuit arrangement, two square wave signals (Ra, Rb) pass through two channels (K1a, K1b) of a synchronisation unit (SE1) and are present at their outputs as square wave signals (Ca, Cb). If the distances between two successive edges are too small in the two square wave signals (Ra, Rb), the edge-to-edge distances of the square wave signals (Ca, Cb) are increased by such an amount that correct further processing is made possible. The synchronisation unit (SE1) had the effect that a change in the signal state of one square wave signal (Ra, Rb) at its input suppresses a change in the signal state of the other square wave signal (Ca, Cb) at its output for a predeterminable time interval. <IMAGE>

Abstract: A heat conducting interface unit (16) for use in mounting an electronic module between cooling plates (40), includes an elongated flexible, U-shaped, highly heat conductive metallic heat exchange member (70) adapted to receive a condensor end (16) of the electronic module. The heat exchange member (70) is located within a housing (60) which provides liquid coolant chambers (61, 62) on the outside walls of the heat exchange member (70). The coolant is supplied under pressure through inlets (63) in the housing (60) from corresponding ports (50) in the cooling plates (40). The pressure in the coolant chamber (61, 62) urges the flexible metallic heat exchange member (70) into increased contact pressure with the condensor portion (16) of the electronic module, reducing the thermal resistance across the contact interface, increasing the rate of heat transfer to the cold plate (40), and clamping the module in position. The heat exchange member (70) covers the entire surface of the condensor (16) to maximize heat transfer. It also provides a simple structure and a short thermal path to the coolant.

Abstract: An apparatus for machining a non-circular workpiece, wherein the profile data of plural sections of the workpiece stored in the profile data storage means are transformed into the frequency functions of 1 to n degree which is a function of the rotary angular velocity of the workpiece. The calculation means finds the amplitudes and the phases of each degree of the frequency function of each of plural intermediate sections by means of the interpolation according to the position between selected two sections based on the frequency functions of the selected two sections so as to obtain high frequency functions and low frequency functions which are then converted to high frequency and low frequency profile data. The machining apparatus actuates a linear motor in accordance with the high frequency profile data and actuates a PZT actuator in accordance with the low frequency profile data. The actuations of these actuators are accomplsihed in a synchronized relationship with the rotation of the workpiece to machine the workpiece into a non-circular shape whose sectional shape changes with respect to its axial position.
