Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a surfactant that is soluble in an acidic aqueous medium.  This surfactant is useful as an emulsi-fier particularly as an emulsifier for the preparation of latex polymers for example the latex polymerization of vinyl acetate. The copolymers of the present invention have 3 very low level compared to compounds of the prior art of ethylenically unsatu-rated monomer which contains a sulfonic acid (or its salt) substi-tuent. The use of such low levels of the sulfonate containing monomer is advantageous since such monomers are expensive. The surfactant is a copolymer containing the groups  ,          ,       and    , and having one R-Z- group and one -H group as terminal groups wherein R is a hydrocarbon group Z is -S-,   or  ;            R1 is -CO2CH3, -CO2C2H5, -CONH2 or -CN; each R2 each R3 each R4 each R5 and each R7 may bs the same or different and each R2, R3, R4, R5 and R7 is either hydrogen or methyl; R6 is a group of the formula -V-CO2H or its salt wherein V is alkyl, aryl aralkyl or alkaryl; W is a group containing a sulfonic acid or a salt of a sulfonic acid or W is a sulfonic acid group or its salt.

Abstract: ABSTRACT OF THE DISCLOSURE           A surgical light assembly employs three fixed, coaxially-arranged curved reflectors with a single movable light source mounted for limited movement along the axis of the reflectors to focus the light.  The light source and at least the reflective surfaces of two of the reflectors are enclosed so that convective currents over these surfaces are precluded.  The light is cooled by a heat sink mounted in heat transfer relation with the light source, with the heat sink having a major surface exposed to atmosphere to dis-sipate heat.  Glare is minimized by precluding direct viewing of the light source from outside the light assembly.

Abstract: ABSTRACT         This invention relates to a scanning electron micro-scope with a periodic structure in the object plane used for the detection of the focus condition of a spot focused electron beam scanning an object in order to correct defocussing and astigmatism in the scanning electron beam spot. To achieve this the detector comprises a plurality of individual elements which can be pair-wise read and an electronic circuit for forming a control signal for controlling the excitation of a spot-forming lens and a stigmator, respectively, from signals representing movement of the electron interference pattern at the detector, relative to the object scan, due to an out of focus condition, the signals being derived from corresponding pairs of detector elements which are situated at a fixed distance from each other in order to correct the focus and compensate for the astigmatism in the electron beam respectively.  In the case of astigmatism, signals from at least two pairs of detector elements spaced in directions at right-angles to one another, are used.  The inven-tion overcomes the drawback associated with other known methods wherein the lens current must be frequently and continually readjusted.

Abstract: Beloit No.:  2585 Rader Inventor:    Louis R. Allard Title:    "Raker Apparatus"                    ABSTRACT OF THE INVENTION           A raker boom supports a plurality of independently driven and mounted rotatable raker wheels which are applied to the face of a pile of material to dislodge and move the material downwardly toward a bucket wheel and conveyor for gathering and conveying the material to a remote location for processing.  The boom is capable of rotating in a vertical plane so that the raker wheels can contact and remove all of the material through the depth of a pile.  By operating the raker wheels individually and mounting them independently, the raker apparatus can travel and apply the individual raker wheels over the surface of a pile of material regardless of its contour.  The wheels can break up lumps of material, especially on the surface of the pile, and mix the material with other material within the pile.  In one configuration of the preferred embodiment, a pair of opposed raker wheel booms are mounted on a raker carriage which itself is mounted for reciprocal travel on a raker truss.  The whole raker truss then travels over the area of the base of the pile of material at right angles to the direction of reciprocating movement of the raker carriage.  In another configuration of the preferred embodiment, the raker truss rotates about the center of a pile of material. The truss can be designed to rotate in only one direction, so only one raker wheel boom is needed.

Abstract: IMPROVEMENTS IN OR RELATING TO STOPS FOR LINES      Abstract Stops made of a synthetic plastics material in two parts welded together at least at individual locations with a fishing line made of "Nylon". The two parts surround with their inner surfaces a hollow space and form an inner wall with elevations. On welding by means of an ultrasonic field at least edges of the elevations melt together with the fishing line and form a non-detachable connection. By means of radial grooves on the outer side the rigid stop achieves a certain movability so that a certain transfer from line to stop does not cause any break in the line. Such stops are suitable in ocean fishing for limiting the length of displacement of the swivels.
