Title: Photocurable composition comprising maleic anhydride adduct of polybutadiene or butadiene copolymers
Inventor: BERRIER ARTHUR LEROY
IPC: C08C19/36
Filed: 1991-04-17
Abstract: An aqueous-developable article is made from a photoprepolymer made by reacting a maleated polyalkadienyl homo- or copolymer (e. g., polybutadiene) with an olefinically unsaturated compound capable of opening anhydride rings (e. g., hydroxyethyl methacrylate) with simultaneous chain extension using a polyalkadienyl polyol, followed by hydrolysis and neutralization with Li-, Na-, or K-containing base. When formulated with unsaturated monomers and photoinitiators, the photoprepolymer is particularly useful in making photopolymer-based flexographic printing plates.

Title: Infrared holographic defect detector
Inventor: CHANG DAVID B
IPC: G01B9/021
Filed: 1991-05-08
Abstract: ABSTRACT OF THE DISCLOSURE       An infrared holographic defect detector (10) comprises a far infrared pulsed coherent source (14) of infrared radiation which provides infrared radiation.  The radiation is directed at a generally non-reflective surface (12), for example, a surface of an automobile body having a matt grey pre-coat thereon.  A semi-transparent mirror (15) is placed in the path of the radiation to provide a reference beam (17) therefrom. An infrared detector (18) and a charge-coupled device (20) receives the radiation reflected from the surface and the reference signal.  A comparator (22) compares the received reflected information and the reference signal and, preferably, information from a source (24) which defines a desired surface configuration in order to derive a quantitative measurement of the surface.  A monitor (26) visually displays the quantitative measurement and location of any dents in the surface.  To avoid a requirement that sequential automobile doors containing the surface of investigation be three-dimensionally aligned to within microns of reference points, a detector of the reflected radiation can be translated and rotated.  A number of sensed images of the surface are taken, one at each of the different positions of the detector.  For each image a measure of its correlation with the standard image is made.

Title: Apparatus for compacting used tires
Inventor: ALLEN LEWIS E
IPC: B30B15/00
Filed: 1991-06-26
Abstract: ABSTRACT OF THE DISCLOSURE    A device for compacting used tires has a rigid base member, a pair of columns rising from the base member, a top beam joining the uppermost extremities of the columns, and a movable engagement member adapted to slide upon the columns.  A shaft vertically penetrates the top beam and is pivotally attached to the engagement member.  In use, tires are stacked upon the base member, and the shaft, which is essentially a piston component emergent from a pressurized fluid chamber, is caused to force the engagement member downwardly.  At the downwardmost point of travel of the engagement member, the tires are tied to form a bale.  Retaining assemblies adjustably positioned upon the columns permit tires to be accumulated in multiple pressings prior to baling.

Filed: 1991-07-11
Abstract: Abstract of the Disclosure The present invention provides a support arm for optical accessories such as are used during the examination of eyes for determining the corrective eyeglass lens required.  The support arm is supported by a vertical support post which defines a first axis about which the arm may be pivot.  The support arm further includes a first hub portion adjacent to the support post and a second hub portion distal from the support post wherein a vertical mounting shaft extends from the second hub portion for supporting an optical accessory.  A parallelogram structure extends between the first and second hub portions such that the second hub portion may be moved vertically relative to the first hub portion about a second horizontal axis located at the first hub portion while maintaining the mounting shaft in a vertical position.  Further, the mounting shaft for the optical accessory maybe rotated about a third axis along the longitudinal axis of the shaft to position the optical accessory at different locations around the second hub portion.  The weight of the optical accessory is counterbalance by a tension spring which biases the parallelogram structure to a horizontal position and thus counteracts the weight of the optical accessory.  The support arm is further provided with a locking lever mounted to the second hub portion for simultaneously locking the support arm against movement about the first, second and third axes.

Title: Method and apparatus for analyzing the state of protection against corrosion of a work under cathodic protection
Inventor: CALLOT PIERRE
IPC: G01N17/02
Filed: 1991-12-27
Abstract: ABSTRACT     "Method and apparatus for analyzing the state of protection against corrosion of a work under cathodic protection"         The subject of the invention is the study of the changeover time of the voltage between an electrode (9) and a metal work (1) buried in the ground (3) and pre-sumed to be protected against corrosion by an electric current.        For this study, it is intended momentarily to interrupt the circulation of the protective current, to read the voltage between the work (1) and the electrode (9), to pass these readings to an analogue filter (11), to smooth these filtered signals by substituting them with values corresponding to a continuous and monotonic postulated function, and then, the said filtering opera-tion having distorted the said signals, to mathematically reconstruct the change in the voltage signals between the work and electrode such as it would be without analogue filter.        The  invention  applies  to  the  study  of  the cathodic protection of gas pipes.
