Abstract: A B S T R A C T             "METHOD AND APPARATUS FOR MAKING A    PATTERNED NON-WOVEN FABRIC"    A non-woven fabric having a pattern defined by an array of discrete areas having a reduced fibre density but which are substantially free of perforations is produced by supporting a freshly wet laid web of the non-woven fabric on a porous surface and directing spaced jets of fluid against the unsupported side in order to displace fibres within discrete areas whilst maintaining in position a proportion of fibres that are within those areas and that are adjacent the porous surface.  The fabric web may be supported on a Fourdrinier wire (1) and the jets of fluid (e.g. water) may be directed through the apertures in a perforated cylinder (6), the Fluid being supplied under pressure from a water-knife device (11).  The apertures in the cylinder (6) preferably have a cross-section that increases in the direction of the water jets. Vacuum may be applied through the Fourdrinier wire (1) by means of a vacuum box (10) and vacuum may also be applied within the cylinder (6) from means (17) in order to remove excess water from within the cylinder (6).

Abstract: ABSTRACT OF THE DISCLOSURE        A lock-in amplifier includes a phase-sensitive detector having a signal input and a reference input.       The output signal from detector is compensated for offset errors which are dependent on the frequency of the reference input and on ambient temperature changes by having a correction signal added to it in an adder.  Changes in gain are compensated for by the addition of a compensation signal in an adder.  Phase errors are compensated by providing a phase shifter for the reference input.  The dc correction, gain compensation and phase correction signals are obtained from a controller which provides digital signals the values of which are derived from a memory, a temperature transducer and a reference input frequency meter.

Abstract: ABSTRACT OF THE INVENTION         An injector for a high temperature gas distribution means comprising a distribution manifold having a heat-re-sistant lining with a central passage therethrough, and a refractory-lined injector communicating with the distribution manifold.  The injector includes a nozzle disposed external to the manifold having a central opening and an inlet extending from the nozzle to the central passage.  The cross-sectional area of the central opening in the nozzle in the direction of flow is smaller at least at one point than that of the inlet such that a major portion of the pressure drop in the gas flowing from the central passage through the inlet and the nozzle is created by the nozzle.  By disposing the injector external to the distribution manifold, the flow rate of gas through cracks in the heat resistant manifold lining is minimized.

Abstract: MICRODROPLETS OF WATER-INSOLUBLE DRUGS               ABSTRACT OF THE DISCLOSURE          Microdroplets of water-insoluble drugs coated with a phospholipid are prepared by sonication.  As an example, microdroplets of the general anesthetic methoxyfluorane coated by a unimolecular layer of dimyRistoyl phosphatidylcholine are prepared by sonication.  The microdroplets so prepared remain stable in physiologically-compatible solution, and are suitable for injection, typically intradermal or intraveneously, into a patient for inducing local anesthesia.  These methoxyfluorane-containing microdroplets have been demonstrated to cause long-term local anesthesia when injected intradermally, giving duration of anesthesia 28 times longer than with other anesthetics, such as lidocaine and 11 times longer than with bupivacaine.  The latter is considered longest acting conventional local anesthetic.  The microdroplet is also capable of solubilizing and delivering benzocaine and other water-insoluble drugs, and thus represents a novel drug delivery system and general method for delivery of water-insoluble drugs, lowering the necessary dose and providing a more direct and timed release.

Abstract: ACTUATOR FOR ADJUSTABLE HYDRAULIC DAMPER Abstract of the Disclosure The actuator is disposed in the damper piston rod and includes a solenoid with a reciprocating plunger, a motion converting mechanism which converts solenoid reciprocation to rotation of an input driver, an intermediate driver rotatable with the input driver, a rotatable output driver connected to a valve adjusting rotor in the damper piston, and a torsion spring between the intermediate and output drivers. The spring holds the output driver in a following relation to the intermediate driver so that when pressure spikes immobilize the valve rotor and output driver, the input driver can continue to rotate to a control position.  When rotor mobility returns, the spring automatically advances the output driver and valve rotor to the same position which would have been achieved had the rotor not been temporarily immobilized.

Abstract: ABSTRACT OF THE DISCLOSURE        A device for loading granular material containing some foreign matter into a container, such as a railroad car, has upper and lower chutes arranged in parallel.  The upper chute has a bottom screen for allowing the foreign matter to fall through to the lower chute.  The grain flow remaining on the upper chute is discharged down the center of the car and fills toward the sides, while the foreign matter falling to the lower chute is distributed evenly by sidewardly extending wings out toward the sides and in towards the center of the car.  By the operation of the device, the foreign matter carried in the grain is evenly distributed and mixed throughout the car, and the tendency of the foreign matter to concentrate along the center under the hatchway of the car is prevented.  A sample of the grain taken from the hatchway of the car thereby contains a truer percentage of foreign matter to grain than would occur by conventional loading devices.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus for use in depositing viscous food mix onto a conveyor which carries deposits of the food mix through an oven.  The apparatus includes a hopper into which the food mix is loaded and an array of dies at the underside of the hopper.  Counter-rotating rollers are located within the hopper and they are driven at periodic intervals to force a predetermined quantity of the food mix to be extruded downwardly through the dies at the periodic intervals.  A shearing mechanism, which includes two reciprocating blades which are mounted in overlapping relationship, is located at the underside of each die for severing the extruded mix from that remaining in the die.  The two blades associated with each die are formed with apertures, the blades being driven in such a manner that the apertures align when the blades are located in a first position and move out of alignment when the blades are driven to move into a second position.
