Abstract: ABSTRACT         The invention concerns a novel process for the racemisa-tion of unwanted enantiomeric forms of 1'-substituted spiro[imi-dazolidine-4,3'-indoline]-2,2', 5-triones and 1'-substituted spiro[pyrrolidine-3,3'-indoline]-2,2', 5-triones which comprises heating an unwanted enantiomeric form (or a mixture containing an excess of one enantiomer over the other) alone or, more conven-iently, in the presence of a solvent or diluent at a temperature in the range 80 to 280°C.  These compounds have the general formula   wherein Ra is (2-12C)alkyl, or naphthylmethyl or cinnamyl optionally bearing one or two halogeno substituents, or benzyl optionally bearing one or two substituents independently selected from halogen, (1-4C)alkyl, (1-4C)alkoxy, cyano, nitro and tri-fluoromethyl located in the 2-, 3-, 4- or 5-position of the phenyl moiety; benzene ring A optionally bears one or two substituents independently selected from halogeno, (1-4C)alkyl, trifluoromethyl and nitro; and Q is methylene or imino; but Ra is other than ethyl, n-propyl or unsubstituted benzyl when benzene ring A is unsubstituted and Q is imino.

Abstract: ABSTRACT OF THE DISCLOSURE            A performance monitor generates a fouling factor which indicates the level of fouling of a heat exchanger having a heat exchange surface area and through which a heat exchange medium passes having a known specific heat.  Temperature transmitters are utilized to obtain values for the input and output temperature of the heat exchange medium as well as the temperature in the heat exchanger of a heat exchange fluid used to transfer heat to or from the heat exchange medium.  Modules are used to generate a value for an actual heat transfer coefficient in the heat exchanger as a function of the temperatures, flow rate and constant parameters such as area and specific heat, for the heat exchanger.  The actual heat transfer coefficient is compared with a nominal or original heat transfer coefficient to determine if any deterioration in the coefficients which reflects the fouling of the heat exchanger.  A simple ratio of the nominal to actual heat transfer coefficent is taken as a measure of this fouling factor.

ARMSTRONG                        ABSTRACT A supported silver catalyst for the oxidation of ethylene to ethylene oxide with molecular oxygen is made by impregnating a support with a hydrocarbon solu-tion of a silver salt of a neo-acid having 7 or more carbon atoms, substantially free of water and said neo-acid.  Preferably, the hydrocarbon solvent is toluene, xylene, ethyl benzene, cyclohexane, or cumene.  The impregnated support is dried and the silver is activated under conditions chosen to provide the optimum selecti-vity to ethylene oxide. Thereafter, the activated silver catalyst maybe impregnated with an alkali metal solution sufficient to increase selectivity of the silver catalyst above its alkali-free state.  The amount of alkali metal on the finished catalyst is the optimum for the par-ticular support selected and preferably will be about 1 -6x10-3 gew/kg of catalyst.  The catalyst may also include additional promoters, such as the alkaline earth metals, preferably barium.

Abstract: ABSTRACT      Semiconductor integrated word organised store comprising a two-dimensional array of bistable storage cells linked by orthogonal word lines and pairs of bit lines.  Each cell consists of two cross-coupled MTL  gates  having  a  structure  providing  a  vertical  inverting  base transistor and two complementary lateral injector transistors.  A cell is driven by read/write logic connected to the word lines and bit lines only.  To read the contents of a word from the array, read logic drives the read injectors of the cells constituting the word at a high injector current  level  and  the  read injectors  of all other cells  at  a  low injector current level.  To select a word for writing, the read logic drives the read injectors of the cells comprising the word at a low injector current level and all other cells at a high injector current level.  The contents of the selected word may then be charged by dif-ferentially driving the cell write injectors over the bit lines.  Output multiplexing of cells storing corresponding bit positions in the words is achieved simply by connecting the cell outputs together (dot ANDing). Logical output discrimination and interfacing is achieved by comparing the multiplexed output current with a threshold current.  If the output current is less than the threshold the cell is storing a logical ONE. If the output current is greater than the threshold the cell is storing a logical ZERO.

Abstract: Abstract of the Invention A simple,  light weight air cooled filter arrangement for a high intensity narrow band pass filtered light fixture.  In lighting fixtures such as infrared energy sources or stage lighting,  it is necessary to filter a conventional broad spectrum energy source so that only energy in the desired region is transmitted.  These filters which absorb energy in bands other than those being transmitted tend to become very hot particularly when high energy sources are required.  A light fixture is provided having a plurality of spaced filters near a light output end.  Each filter, except the outer most filter, has a portion of its outer periphery removed.  These open areas are alternately positioned to form a tortuous air path between adjacent filters.  A cooling fan draws filtered exterior ambient air through the tortuous paths between the filters and exits the warmed air past the energy source out the end remote from the filters.  Sensors are provided for controlling the output of the energy source relative to exterior light and exiting air temperatures and the fan operation.

Abstract: Abstract:         A dual processor system with duplicated memory has two modes of operation: a converged mode in which one of the two processors is active and executing all system tasks while the other processor is inactive; and a diverged mode in which both processors are active and independently executing different tasks.  The system automatically changes modes in response to requests such as manual and program control and certain system fault conditions.  In diverged mode, the system may be in either of two states of operation.  In one state one processor is designated a primary processor, and in the other state the other processor is designated the primary processor.  In the converged mode the system may be in either of four states of operation.  In two of these states one processor is active while the other processor is standing by ready to take up execution of tasks from the point where the one processor stopped execution.  In the other two of these states one processor is active while the other processor is out of service and cannot take up task execution with-out being initialized.  The system 100 makes transitions between the various states in response to requests. Except for transitions of an active processor to an out-of-service condition, the state transitions are transparent to tasks other than fault recovery programs and, upon a fault condition, the faulted program.
