Abstract: ABSTRACT OF THE DISCLOSURE         A toy vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are adapted to be operated. The toy vehicles each include a reversible rotary drive motor and a transmission operatively engaged between the motor and two drive wheels for rotating one or the other of the drive wheels in response to the direction of rotation of the drive motor, thereby biasing the car against one or the other of the side walls of the track to guide the vehicle along its path of travel in one or the other of the lanes. The track includes electrical contact strips which supply power to the drive motor of the vehicles through current collectors mounted thereon. A control system permits the operators to separately and inde-pendently control current to the contact strips and also to selectively reverse the polarity of the current so that the operators can vary the speed of their associated vehicles and cause the vehicles to move from one lane to the other. In one form of the invention an additional toy vehicle operated as a drone car at constant speed is provided presenting an obstacle along the track which the player must pass by properly controlling their respective toy vehicles.

Abstract: ABSTRACT A selective vaporization process is conducted by contacting a heavy charge stock such as whole crudes, topped crudes, resids and the like with an inert, finely divided solid material in a confined vertical column under conditions to deposit heavy components of high CC and/or metal content on the solid and vaporize other components of the charge.  This results from temperatures high enough to cause the desired vaporization and very short hydrocarbon residence times to avoid substantial cracking.  The operation is thus held to a low cracking severity to accomplish the desired purpose of separating vaporizable, more valuable components from those which are regarded as contaminants.  Steam, light hydrocarbons or the like are added to the rising confined column in the selective vaporization facility to reduce partial pressure of hydrocarbons in the charge and thus aid in vaporization.  Vaporous hydrocarbons are separated at the top of the column from inert solids bearing the unvaporized components as a deposit thereon.  The vapors are promptly cooled to a temperature below that at which substantial thermal cracking occurs and processed as desired in a catalytic cracker or the like.

Abstract: Method and Means for Utilizing Apodized Beams Abstract Apodized beams of electromagnetic radiation are used in a transmissometer and earth motion detector.  A laser beam which is apodized by a conical scanning means is transmitted from a device to a remote point where it is retroreflected to the device to provide measurements re-lating to the transmissivity of the physical environment.     In a different application the conically scanned apodized laser beam is directed to a retroreflector which is then returned to the transmitting point.  Relative movement between the transmitting point and the remote point are detected by the change in beam position with respect to the retroreflector.  With several transmitters and receivers orientated at different propagation angles different rela-tive movement parameters are obtained.  The conically scanned laser beam has substantially Gaussian intensity profile, but alternative symmetrical profiles of other electromagnetic radiation can be used.

Abstract: A COUPLER LATCH MECHANISM WITH A SELF-OPENING FEATURE     Abstract of the Disclosure A coupler latch mechanism is disclosed having a self-opening hook-up feature for facilitating the hook-up of an implement to the hitch on a tractor.  The coupler latch mechanism includes a latch bar pivotally connected to a coupler frame immediately above a hook.  A trigger member is pivotally connected to a midsection of this latch bar and has a downwardly projecting finger which is located rearward of the lower portion of the latch bar.  The forward end of the trigger member is pivotally connected to a link, which is in turn pivotally connected to the frame.  The point of attachment of the trigger member to the link is also the point of attachment of the trigger member to a vertical rod, which extends up through the frame.  The upper end of the rod is pivotally attached to a lever pivotally connected to the frame.  The control latch mechanism is able to open as an implement hitch pin presses against the finger of the trigger member.  This action causes the trigger member to pivot on the latch bar forcing the rod up and the lever to open.  As the lever opens, the latch bar moves clear of the hook and permits engagement of the implement hitch pin. The lever will then remain open until the operator manually closes it.

Abstract: TITLE ETHYLENE OXIDE REACTOR          INVENTORS Brian J. Ozero Stanley D. Becker ABSTRACT Improved performance is obtained in a multi-tube reactor for oxidation of ethylene to ethylene oxide by providing a distribution zone for the coolant located downstream of the catalyst and a contiguous cooling zone. The effluent gases from the oxidation are cooled.in the cooling zone by a fluid, which has been only slightly preheated and distributed uniformly in the distribution zone by contact with tubes in which the effluent gases are in low-turbulence flow.  Uniform distribution of the coolant provides substantially equal cooling of the effluent gases in each tube, thus minimizing the variation in effluent gas temperature among the tubes.  Preferably, the tubes in the cooling section are packed with inert particles to facilitate heat transfer, while the tubes are empty in the distribution section to reduce heat transfer.

Abstract: DE DIVULGATION: Procédé de production de supercarburant par polymérisation des coupes C4. Le procédé consiste ainsi à soumettre d'abord la charge, c'est à dire la coupe C4 oléfinique, charge généralement débarrassée d'au moins la majeure partie du butadiène qu'elle peut contenir, à une première réaction de polymérisation au cours de laquelle les conversions globales des butènes normaux contenus dans la charge restent inférieures à 45% en poids et au cours de laquelle on convertit au moins 80% en poids de l'isobutène présent, ces hydrocarbures se transformant essentiellement en dimères et trimères. Ensuite, le produit sortant du réacteur est soumis à un fractionnement en vue d'obtenir, d'une part, une première fraction, contenant de l'isobutène et des butènes n'ayant pas réagi, que l'on envoie au moins en partie vers une deuxième zone de polymérisation différente de la première zone de polymérisation, dans laquelle les conditions opératoires sont optimisées pour transformer les butènes normaux en dimères et trimères, et d'autre part, une deuxième fraction constituée essentiellement par les dimères et trimères de l'isobutylène que l'on envoie au pool essence. Ainsi, la première fraction très riche en butènes normaux, n'ayant pas réagi, ainsi que le reste de l'isobutène non transformé, sont envoyés vers un deuxième réacteur d'isomérisation où les oléfines présentes sont transformées en majeure partie en dimères et trimères des oléfines présentes. On convertit ici pratiquement à 100% l'isobutène présent et au moins 50% en poids des butènes-1 et 2 et de préférence on effectue, dans ce réacteur au moins 75% en poids de conversion du butène-1 et plus de 55% en poids de conversion des butènes-2. Et une installation pour mettre en oeuvre ce procédé.
