Title: Apparatus and methods for analyzing a system of processes
Inventor: FOWLER GLENN STEPHEN
IPC: G06F11/32
Filed: 1994-10-14
Granted: 1999-02-02
Abstract: Techniques for analyzing and controlling operation of a system of cooperating processes. A library of system calls used by the processes is replaced by a dynamically-linked library which performs the system calls and also sends messages including that the system calls have been performed. The messages are received by a display system which responds to the messages by making a graphical display showing the current state of the system of processes. The graphical display displays the system of processes as a tree. Nodes in the tree represent the processes in the system and resources such as files used by the processes; edges in the tree represent relationships between processes and other processes or resources. Users may control which system calls result in messages, may control the rate at which the displaysystem responds to the messages, and may also control execution of the processes.

Abstract: A drive circuit for use with an ambient condition detector limits heat dissipation and associated temperature rises in the presence of varying RMS values of an applied AC signal. The drive circuit includes a voltage doubler with a current regulator located between first and second storage elements. In the presence of a sensed ambient condition, which exceeds a predetermined threshold the regulator is enabled permitting one of the storage elements to be charged to a voltage on the order of twice the peak value of the applied AC voltage. A digital timer is used to trigger a flashable visual indicator from the stored DC voltage. The regulator provides a substantially constant DC voltage to the visual indicator in the presence of a varying AC line voltage.

Abstract: This invention provides a method for reducing fifty-fold the size of equipment required for making a given volume of alkyltin thioglycolic acid esters.  In said method,  an alkyltin thiocarboxylic acid ester is made from the corresponding alkyltin halide and thiocarboxylic ester  in a continuous process that requires but one agitated reaction vessel.  The organic reactants and an acid acceptor are added simultaneously to a reaction vessel equipped with agitator impellers and containing a sufficient level of water to provide an agitatable medium.   Extremely vigorous agitation  (at  least about 75 turnovers per minute,  which is sufficient to achieve a fluid velocity across the impeller(s) of at least about 50 feet per minute) is employed to avoid side reactions which often cause the formation of a tenacious, stringy emulsion, the breaking of which requires a rather difficult and wasteful filtration.   Continuous withdrawal of the reaction mixture from said reactor  is commenced promptly after commencement of the additions and said mixture  is continuously separated  into an aqueous phase and an organic phase as it is withdrawn without the need of demulsification means.  The pH of the reaction mixture is greater than 7 but the maximum is about 8.2 and the temperature is from about 40 to about 80°C.

Title: Method and apparatus for testing electronic memories for the presence of multiple cell coupling faults
Inventor: COCKBURN BRUCE FORDYCE
IPC: G11C29/12
Filed: 1994-08-03
Granted: 1998-04-14
Abstract: A method of testing a random access memory (RAM) for single V-coupling faults by establishing a first current value for each cell, for each cell and for each of m data backgrounds, generating a data bit corresponding  to  an  element  of  an  (n,  V  -  1)-exhaustive matrix, and for each of m data backgrounds: (1) applying a read write sequence to each cell; and (2) for each background except the mth background, updating the current value of all cells according to the data bits corresponding to that cell; reading each cell of the RAM; and discarding or repairing the RAM if a cell coupling fault is apparent from the series of values read from the cells of the RAM. Data bits are generated by a matrix reconstruction method or a pseudo-random generator using a hashing of the address of the cell to which the data bit is to be applied. The logical function may be the element of the (n, V -1)-exhaustive matrix irrespective of the current of the cell or an exclusive-or of the complement of the background code logic bit and the first current value of the cell. Apparatus for testing a random access memory (RAM)  has a PROM containing background code logic bits corresponding to an (n0, V - 1)-exhaustive matrix where n0  n, the matrix having n0 rows and m0 columns; and a data bit generator for generating data bits from the matrix stored in the PROM. A built in apparatus for testing a random access memory (RAM) having n cells includes a data bit generator that generates pseudo-random data bits from a hashing of the address of the RAM cell to which the data bit is to be applied.

Abstract: The invention describes a feed device that feeds assembly parts such as nuts, bolts, and rivets, from a sorting unit to the feed channel of a processing device for pressing or mounting of assembly parts to sheet metal. The feed device consists of a nozzle with a nozzle channel through it connected on one end to a feed line coming from the sorting unit. A protrusion of the nozzle can deploy into a recess opening of a guide piece of the processing device so that the nozzle channel will open laterally into the feed channel of the device. To connect the nozzle to the guide piece, two levers linked to the nozzle are used; they are pretensioned by springs in a closed position surrounding the guide piece and can be moved manually, possibly with the assistance of a tool, into an open position. In this manner the feed device can be easily connected to the processing device and then detached from it (Figure 1).

Abstract: With only an understanding of the functionality to be provided by a service, one can quickly and easily develop or create such a service by, in accordance with the principles of the invention, selecting and arranging instantiations of predetermined "pictures", e.g., icons, into a multilevel outline which generallyspecifies the service logic of the desired service. Each picture represents a "service building block", e.g., a high level process part and its customizable attributes, and for each instantiation of a picture in the multilevel outline there exists a corresponding instantiation of a service building block. The operation of the instantiations of the service building blocks are customizable in response to attributes supplied by the service creator. A service development system arranges instantiations of the service building blocks, in response to the operations on the pictures, to develop a program that implements the service logic as specified by the multilevel outline. The display of the graphical multilevel outline may be expanded or collapsed by the service creator for viewing convenience without affecting the service logic or attributes of the corresponding service.

Abstract: The present invention describes an air filtering apparatus disposed within a housing having at least an optical baffling means, an air-permeable material downstream from the optical means, an irradiation means within a sterilizing chamber, and a blower further downstream from the irradiator. The air-permeable material is the "see-through" type where light can pass through the cross section areas of the material. Chemicals may be added/incorporated/sprayed onto this air-permeable material to kill micro-organisms when they come into contact with the air-permeable material. At least one irradiator is arranged for directing ultraviolet radiation onto the inner surfaces of the air-permeable material. With the "see-through" type air-permeable material, the irradiation from the irradiator kills most micro-organisms in the cross section areas including both surfaces of the air-permeable material. As such, the improved air filtering apparatus of the present invention is near germ free. The blower is provided to draw air through the optical baffling means, the air-permeable material and the radiator. The optical baffling means minimizes the emission of radiation from within the housing; similarly, the blower eliminates any radiation leak from within the same housing.
