Abstract: Process for preparation of multicolor images on a single negative-working photosensitive layer which comprises imagewise exposing the layer through a transparency to form tacky image areas; toning the tacky image areas with a toner which becomes swollen or solubilized upon contact with the tacky areas; buffing or rubbing the toned image areas until glossy; and repeating the exposing, toning and buffing or rubbing using a different image-bearing transparency and appropriate toner. The process is useful in preparing multicolor proofs, e.g., maps, textile and wall covering design proofs and samples, etc.

Abstract: A process of forming an image of toner on a latent magnetic image in a magnetic imaging member followed by transfer to a heated transfer member. The transfer member is formed of a backing sheet coated with polyvinyl alcohol. The toner image is then transferred to a substrate using heat and pressure. The backing sheet portion of the transfer member is then stripped away and the polyvinyl alcohol is washed away with water. The surface portion of the substrate not protected by the transferred resist toner image is then permanently modified by etching or plating. Chemically milled shapes are prepared as well as printed circuits and printing plates. The printed circuits may be formed by (1) etching away areas of a metal surface not protected by the resist, (2) electroless plating on areas not protected by the resist or (3) electroplating areas of a metal surface not protected by the resist, removing the resist, and in the case of (2) and (3), etching away the metal previously covered by the resist.

Abstract: Pyrazolo [3,4-d] pyrimidine, and derivatives thereof, can be added to either a silver halide emulsion, or to a hydroquinone (litho) developer to accelerate development and reduce the induction period.

Abstract: A spirometer device includes an open ended inflatable elastomeric vessel with calibrated indicia along its length for indicating the volume of gas contained in the vessel and a mouth piece consisting of two relatively rotatable sections, one of said sections being connected to the open end of the vessel so that air can be blown through the mouth piece to inflate the vessel. The mouth piece contains a unique valving system and an air actuated sound generating device so that depending upon the relative angular relationship of the two sections, air can be blown into the vessel and retained in the vessel or allowed to escape from the vessel either through the sound generating device or not.

Abstract: The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy compound, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.3. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.

Abstract: Polyvinylbutyral sheeting, plasticized with a hydrolyzable ester, having low acid concentration through the use of formic acid salt as an adhesion control agent.

Abstract: A solar heating system in which the heating transfer medium is circulated from the heat absorbing member through the heat exchange area by means of gravitational forces which are augmented by the use of a transfer medium containing additives which change in state from fluid to gaseous as they move through the system. An emulsifying agent is also employed within the circulating fluid to prevent agglomeration of the additives. The use of one or more additives within the circulating fluid depending upon ambient conditions is disclosed.

Abstract: A toy having combined rotational motion about a horizontal axis and translational motion in a vertical direction. Two parallel discs are connected through their centers by a single axle. One end of a torsion resistant tape is attached to the axle, at a position between the two discs. A swivel system is attached to the other end of the tape, and a ring for holding the toy is attached to the swivel system. In order to operate the toy, the user's finger is placed in the ring and an up-and-down motion is initiated. The balance of the toy during operation is facilitated by the support provided to the axle along the width of the tape.

Abstract: An improved thermoplastic pipe stub end for welding to thermoplastic pipe is disclosed. The stub end has a flange portion integrally joined to a neck portion which has inner and outer surfaces and terminates at a welding face. The improvement resides in the reduction of the length of neck portion such that it extends from the flange a distance in millimeters of not greater than 1.5 .sqroot.O.D., where O.D. is the outer diameter in centimeters of the neck portion at the welding face. The improved stub end permits higher strength heat welds to be made by butt fusion between the thermoplastic stub end and a thermoplastic pipe to be joined thereto.

Abstract: Several types of toy vehicles are provided which automatically lean when negotiating turns. One such vehicle is a radio-controlled toy motorcycle, which carries two outriggers with supports that extend downward from the typical positions of a rider's feet. Each outrigger pivots about two independent axes, to bank the toy for negotiating turns. The outriggers are cam-operated from the same radio-controlled steering mechanism which operates the front fork of the toy to turn it. An articulated toy rider has arms which follow the handlebar motions, and legs which follow the outrigger supports--to suggest the illusion that the rider is supporting the motorcycle with his foot on turns. The radio receiver and control electronics, as well as electric motors to drive the rear wheel and the steering mechanism, are powered by dry cells advantageously mounted in the mufflers.

Abstract: This invention is directed to compounds of the formulas ##STR1## and various intermediates therefore. The final products possess useful hypotensive activity.

The apparatus rotates about a central axis to provide a plurality of stations at which a specific process or step is accomplished.

Abstract: In order to determine the acoustic impedance of a human ear at various static pressures, a probe tightly fitted to the pinna of the ear transmits a short acoustic pulse with a wide frequency spectrum (such as white noise) from an electroacoustic transducer to the ear canal and receives back an acoustic response signal which a microphone converts into an electrical wave. The latter is digitized and transformed into terms of a Fourier series fed to a processor which, on the basis of similar terms stored in a memory and previously obtained with the same probe fitted to two different cylindrical calibrating cavities, derives therefrom the acoustic ear impedance at a particular air pressure. The processor also triggers an electric pulse generator, working into the electroacoustic transducer, and may progressively adjust a generator of static air pressure connected to the probe.

The process provides control of the type and length of the side chain polymer grafted onto the trunk copolymer.
