Abstract: ABSTRACT OF THE DISCLOSURE         A method for making a game ticket, such as for example a lottery ticket, is disclosed in which the ticket has a base sheet and a cover sheet adhesively joined together in peripheral portions of sections containing information used in the game.  The cover sheet, along with other materials placed on the base sheet, conceals the infor-mation to be used in the game and prevents undetected tampering with the ticket.  The ticket is formed from a base sheet on which information to be concealed is printed, and a release coating is deposited over predetermined areas of the previously printed information.  Thereafter an opaque material is applied over  the release coating to conceal the information in the printed areas, which opaque material is adapted to be rubbed off when the ticket is used.  There-after the non-transparent cover sheet is adhered to the base sheet along predetermined areas surrounding the sections of the base sheet defining individual tickets.

Abstract: C-3016                                                D-2,055 Abstract of the Disclosure A vehicle engine has a throttle stop positionable in response to an actuator command signal to determine engine idle speed.  Apparatus is provided to generate speed error signal having both an absolute value and a further character-istic indicative of high or low speed; and further apparatus is provided including a memory effective to store actuator command signals corresponding to specific speed error signals and speed correction apparatus effective to obtain an actuator command signal from the memory corresponding to each speed error signal and supply the actuator command signal to the throttle stop positioning apparatus to correct engine idle speed in the direction of a predetermined desired engine idle speed.  The actuator command signals corresponding to at least the largest low speed error signals have absolute values effective to produce a greater throttle stop movement than the actuator command signals corresponding to the high speed error signals of the same absolute value, so that the control responds at a faster rate to large low speed errors than to equivalently large high speed errors.

Abstract: METHOD FOR THE RECOVERY OF POWER FROM LHV GAS                Abstract of the Disclosure A method is disclosed for the utilization of energy in gas of low heating value discharged from a production well of an in-situ combustion process for the production of oil.          The low heating value gas is mixed with an amount of air that will provide oxygen in an amount that will limit the maximum temperature rise in a catalytic combustion chamber to avoid excessive temperatures regardless of changes in composi-tion of the low heating value gas.  The mixture is preheated and delivered into the catalytic combustion chamber at a temperature exceeding about 400° F. that will cause ignition of the combustibles on contact with the catalyst.  In a preferred embodiment, combustion is accomplished in two combustion chambers connected in series with a heat exchanger between the combustion chambers for cooling the combustion products discharged from the first combustion chamber before they are delivered to the next combustion chamber.  Approximately fifty percent of the total combustion air is mixed with the combustible gas before delivery into each of the combustion chambers.  Effluent from the second combustion chamber is used to drive a gas turbine for generation of power or direct driving of air compressors.

Title: Process for the production of a phenol and a carbonyl  compound by the catalysed decomposition of an aromatic hydroperoxide
Inventor: WIRTH MAX M
IPC: C07C409/14
Filed: 1979-07-31
Granted: 1981-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process in which an aromatic hydroperoxide or formula:        wherein independently R1 is methyl or ethyl, R2 is hydrogen, methyl or ethyl, or where R1 and R2 together form an alicyclic ring of 5 or 6 carbon atoms, R3 is hydrogen or alkyl and R4 and R5 are hydrogen, alkyl or together form an aromatic ring, n is 0, 1 or 2 and n1 is 1 or 2, is converted to a phenol and a carbonyl compound in a catalysed cleavage decomposition reation.  In particular cumene hydroperoxide is converted to phenol and acatone.  Instead of removing the decomposition products from the reactor in the liquid phase and dissipating the reaction heat as in prior art processes the heat is used to remove the phenol and the carbonyl compound in the vapour phase leaving a liquid residue of higher-boiling compounds and catalyst in the case where a liquid cleavage catalyst is employed.  Although a wide range of both solid and liquid cleavage catalysts may be used sulphuric acid is preferred.  Various additives, including the hydrocarbon from which the hydroperoxide is derived and polar reaction products may be added.  Typical reaction conditions are temperatures in the range 120 to 200°C and either atmospheric or sub-atmospheric pressure.  The process of the invention avoids the conventional catalyst neutralisation and removal steps.

Abstract: Abstract of the Disclosure In a compressed-air motor having a reciprocating piston, a piston rod and a piston slide valve arranged parallel thereto, which is suitable, e.g., for driving plunger pumps for paint spraying, the slide of the piston slide valve is reversed at the end of each stroke of the reciprocating piston by the piston rod by means of a snap device.  The snap device com-prises an actuating member which moves in reciprocation between two stops arranged with a longitudinal interval on the slide.  In order to accelerate the changeover process and to simplify and reduce the force required by the snap device, the latter merely consists of a snap lever, the free end of which is connec-ted to the piston rod through a traction spring. The free end of the snap lever simultaneously constitutes the actuating member and drives the slide by striking abruptly against the stops which are preferably individually adjustable.  The snap lever may be constructed as a crank mounted on two sides, the median section of which is the actuating member.
