Abstract: ABSTRACT         The enzyme cholesterase is produced by cultivating a strain of the Achromobacter delicatulus type, isolated from vegetable debris and identified by the symbol NRRL B-12115. Under the described culture conditions, the enzyme is exo-cellular and therefore does not require extraction from the cells.  In addition, the micro organism has a duplication time less than that of moulds and Actinomycetes.  Cholesterol esters of fatty acids can be hydrolysed by adding them to the culture medium be ore inoculating the strain.

Abstract: OBJECTIVE REFRACTOR FOR THE EYE                 Abstract of the Disclosure An objective refractor for the eye is disclosed in which knife-edge optics are utilized.  The knife-edge optics cause characteristic illumination of the retina so that components of sphere and astigmatism can be identified.          Provision for remote reading of the characteristic images is provided with the result that two orthogonally disposed knife-edge images can identify the sphere, cylinder and axis required for prescriptive patterns giving the direction and magnitude of required prescriptive change.  A system of at least two orthogonally disposed, (and preferably four), knife edges with weighted lighting is disclosed for detection.          Utilization of the knife-edge images is made possible by the detection of the low light level images at a detector having low noise level.  A photo-sensitive element divided into a plurality of photo-discrete segments has light from the images proportionally dispersed over its surface.  Such dispersion occurs through a matrix of wedge-shaped segments or alternately in the form of optical elements having cylindrical components.  This dispersion of the light when used in combination with push-pull knife-edge patterns herein disclosed produces detectable low level refractive signal.          An embodiment using an optic having a plurality of side by side optic elements, each element having the effect of crossed cylinders, is disclosed with the detector.  Separate independent and non-interactive positional information on one hand, and refractive information on the other hand, is provided.  Consequently the disclosed refractor is insensi-tive to adjustment and can accommodate a large range of pupil configuration with insensitivity to local retinal variations in light emission.

Abstract: Abstract of the Disclosure A guide assembly for blown plastic tubes to guide and support the tube after its extrusion from a die consists of a frame carrying a plurality of pairs of vertically-extending members distributed circumferentially around the tube.  Each of the vertically-extending members carries a plurality of vertically-spaced parallel radially-inwardly-extending arms.  Each arm of one vertical member of the pair cooperates with a respective arm of the other member of the pair, each cooperating pair of arms having a flexible wire support member extending between these ends, the wire engaging the tube and conforming to its circumference.          As the tube diameter decreases the arms are moved simultaneously radially inward by opposite rotation of the respective vertical members, whereupon the wire conforms to the new reduced diameter, and vice-versa.  The actual contact of the support member with the tube is by side-by-side cylindrical rollers (e.g. of nylon) threaded on the wire.  An additional support means may be provided that engages the centre of the guide wire and, in addition to preventing downward sagging, automatically presses it radially inward with an increasing force as the tube diameter is decreased.
