Abstract: A first input signal (6) is supplied to a register (1) and stored therein. The first input signal (6) and data stored in the register 1) are supplied to a first logic circuit (2). The first logic circuit (2) is con­trolled by an output signal (12) of a flag circuit (21) and selects one of the first input signal (6) and the data (7) stored in the register 1). A second input signal (10) is supplied to a second logic circuit (3). The second logic circuit (3) is controlled by an output signal (12) of the flag circuit (21) and selects one of supplying the second input signal (10) to the register (1) as a clock signal (8) and supplying the second input signal to a peripheral circuit as an input signal (9). The flag circuit (21) supplies the second input signal (10) to the register (1) as the clock signal (8) when the first logic circuit (2) selects the output signal (7) of the register (1), and supplies the second input signal (10) to the peripheral circuit as the input sig­nal (9) when the first logic circuit (2) selects the first input signal (6).

Abstract: In a travelling-wave tube (20), a cylindrically-­shaped slow-wave circuit cavity-defining member (34) is supported by and is thermomechanically bonded to a tubularly-configured vacuum wall member (32). The bonded joint comprises a pair of arcuate grooves (52) extending lengthwise of the slow-wave circuit and positioned diametrically opposite one another about the axis of the tube. A helical or wavy spring (54, 58) lies in each groove and is resiliently biased in intimate mechanical and thermal contact between the groove and the vacuum wall. The helical spring, in particular, can be used as a conduit for exhaust of gases from the travelling-wave tube during its fabrication.

Abstract: An architecture for a low-end, high-performance switch subsystem (10) allows the connection of a multitude of requests per link. The switch subsystem (10) operates a cross-bar switch (16) under the control of a controller, such as a personal computer, to connect selected ones of a plurality of input links (18) to selected ones of a plurality of output links (20). A data structure for the switch subsystem is mapped to the memory of the controller. The switch subsystem comprises three switch servers (12), a request server, a connect server, and an acknowledge server, which perform in a pipelined fashion. An interface protocol for the switching subsystem may be adapted to various applications and allows a connect request to be either queued in the switch subsystem until the requested output link is available or the requestor is notified immediately if the requested output link is not available, so that alternate actions can be taken.

Abstract: It is the object of this invention to provide a method for the preparation of an antiblocking agent which is effective in its antiblocking activity but is considerable less visible in photographic enlargements made from the film containing the antiblock of this invention. 
     There is described a process for the preparation of monodispersed polymer particles between 5 and 10 microns in diameter which comprises preparing a dispersion of monosized seed polymer particles and then adding to this dispersion an ethylenically unsaturated monomer which is different from the monomer used to prepare the seed polymer particles, together with a polymerization initiator and completing the polymeriza­tion, the refractive index of one of the polymers produced being greater than 1.54 and the refractive index of the other polymer being less than 1.54. 
     The refractive index of gelatin is 1.54. There is produced by the process of the present invention a particle which comprises two polymers. Most preferably one polymer has a refractive index which is as much below 1.54 as the other polymer has a refractive index above 1.54. Preferably the final particles comprises substantially equal amounts of the two polymers.

Abstract: Oxo anions (both singly and multiply charged), such as phosphates, polyphosphates, and phosphate esters, serve as additives, and in the case of cationic dyes, may serve as replacement counter-ions, for use in thermal ink-jet inks to reduce kogation significantly. The addition of such additive essentially eliminates kogation for the life of ink pens. Further, such additives will prevent kogation for inks containing dyes with negatively-charged water-solubilizing groups, such as sulfonate and carboxylate.

Abstract: An electrical interconnection, which includes a method for fabricating the device, is disclosed. The interconnection comprises two contact surfaces, on at least one of which is disposed at least one solid metal conical projection in predetermined dimension and location. Rather than necessarily being permanently cojoined, the contact surfaces are attachable and detachable when desired. The conical projections on one contact surface make ohmic contact, either by wiping with an intermeshing like structure on a second contact surface or by contacting a second contact surface which is a substantially flat contact pad. An interconnection, in this invention, is the combination of at least one contact having individual conical projections and another contact, optionally having individual conical projections. The conical projections are formed in metal by electrochemical machining in neutral salt solution, optionally in a continuous foil. The conical projections are also optionally formed on the head of a contact pin.

Abstract: A video color image projector which includes a block of crossed dichroic mirrors for combining the light rays from image rasters on respective monochrome image display devices and a projection lens for projecting the composite color rays so as to form an enlarged color image on a display screen. Each display device has a faceplate which is convex on the interior surface thereof and having thereon an interference filter in the form of an internal angularly reflecting coating (IARC). Each faceplate is liquid - coupled to a negative power lens element, so that the faceplate, coupling liquid (or gel) and such lens element effectively constitute a single negative power field flattener lens at each entrance side of the dichroic block. The composite color rays at the exit side of the dichroic block are projected on the display screen by an assembly of lens elements which includes at least one optically positive lens element. The focal length of the complete projection lens formed by such assembly and each of the negative field flattener lenses may be from 0.5 to 0.9 times the diagonal D of the image raster on each display device, so that the projector is sufficiently compact to be included in a cabinet suitable for consumer television receivers.

Abstract: A membrane gas separation apparatus, typically for separating air, includes a gas separation all 14 containing an array of membranes in the form of hollow fibres 18. The cell 14 has a first gas port 16 and a second gas port 20. Flow of gas to and from the ports 16 and 20 is controlled by a four-port, two-position valve 12. In one position, the valve 12 admits incoming air to the port 16 and allows product nitrogen to flow out of the port 20. In the other position the roles of the ports 16 and 20 are reversed and hence the direction of flow of the gas is reversed. During prolonged operation, there is a tendency for contaminants to affect disproportionately the feed gas inlet and of the membrane fibres 18. By periodically changing the position of the valve 12, different ends of the membrane fibres 18 are presented to the feed gas, and thus the operating life of the membranes 18 is lengthened.
