Abstract: PROGRAMMED LOGIC ARRAY           Abstract A programmed logic array is equipped with a first master-slave shift register on the intermediate wordlines between AND and OR planes of the PLA and a second master-slave shift register on the output lines from the OR plane. In this way, since the propagation delays of both AND and OR planes are much larger than those of the registers, the speed of operation of the PLA is limited to the greater of the propagation delays of the AND and OR plane instead of the sum of these delays as in prior art.

Abstract: Abstract Prefabricated insulated pipeline section having a one-piece cast cured and dried insulative liner formed of lightweight aggregate in a foamed portland cement paste binder bonded to the inner surface of a tubular outer casing.  The liner composition may be cast in place between the liner and the pipe, and wet cured at elevated temperature.  Bonding between the pipe and the liner composition is avoided by employing a cement cure retarder on the outer surface of the pipe or by mechanically debonding the pipe from the liner during curing.  After curing, the pipe is withdrawn to expose the inner surface of the liner to permit rapid drying at elevated temperature.  The prefabricated insulated sections permit simplified pipeline construction at reduced cost as compared with traditional methods of applying half shells of insulation to the pipeline on site.

Abstract: Abstract of the Disclosure An improved universal document validator in which a document is transported along a path past light detectors and associated light sources positioned above and below the path, such that light from the sources is directed toward the path and reflected onto the detectors to produce outputs therefrom.  A first stored value representing the desired output of each detector with no document in the transport path and with its associated light source illuminated is divided by the actual output of each detector with no document in the transport path and with its associated light source illuminated, to produce a plurality of quotients.  If any of the quotients falls outside a predetermined range, the validator turns itself off.  A microprocessor control system uses the outputs of the detectors with a document in the transport path together with the quotients to produce an indication of the validity of the document.

Abstract: ABSTRACT OF THE DISCLOSURE         A dispensing pump is adapted for pressure filling and includes a fluid filling passage which remains sealingly closed during pumping operation by the provision of an annular valve skirt in sealing engagement with a wall of the fluid filling passage, such skirt inwardly flexing during charging the container permitting the charged fluids to by-pass the valve and enter the container.  The valve skirt depends from either the plunger head or from the plunger.  When depending from the plunger, the valve skirt functions  as a guide element for the plunger head together with a plunger head retention bead which cooperates with a pump body retention bead in limiting the upward movement of the plunger head to a predetermined extent.  These guide members serve to isolate the plunger against the influence of lateral or eccentric forces applied against the plunger head during its reciprocation.  And, the plunger may be capped with a wall surface defining a complementary contour to that of the upper end of the piston which it faces to facilitate expelling of product from the accumulation chamber after the end of the plunger downstroke as this surface first bottoms against the upper end of the piston.

Abstract: APPARATUS AND METHOD FOR              PAD BATCH DYEING OF TUBULAR KNITTED COTTON FABRICS            Abstract The disclosure relates to an apparatus and method for pad batch dyeing of tubular knitted fabrics of substantial cotton content, typically 50% or more. One or more connected strings of tubular knitted fabric are advanced toward the dyeing apparatus, where the fabric is gripped across its full width and positively advanced toward the dye solution. A ring guide spreader is positioned in close coupled relation to the driven entry roller and spreads the fabric to flat form and to its natural greige width. Closely coupled to the ring guide means is a dye pad station comprising a pair of horizontally opposed, resilient squeeze rollers, a treating roller forming a submerged dye nip with the front squeeze roller, and a submerged guide roller to receive the fabric as it travels in a downward incline through the dye nip and redirect it to a vertically upward path for passage through the squeeze nip. The squeeze rollers are submerged in the dye liquor to a depth less than half their diameter, so that fabric exits from the dye bath in traveling to the squeeze nip. An exit guide roller is provided directly above the squeeze nip, to guide the dyed fabric symmetrically away from the nip. The submerged treating roller and submerged guide roller are mounted within and by a solution pan for containing the dye, providing unique advantages in terms of mechanical simplicity, facility of clean out and restart for successive batch operations, and processing efficiency. Substantial cost and operating benefits are realized.

Abstract: ABSTRACT      Inserts are disclosed for non-reciprocal waveguide devices.  The insert device comprises a layer of ferrite and a layer of energy absorbing material with a spacer layer between them.  The device works by reason of asymmetrical interaction of the microwave energy and the ferrite whereby energy is preferentially absorbed in the reverse direction. The spacer layer affects the distribution of electromagnetic fields so that there is a relatively low attenuation assoc-iated with one direction and a relatively high attenuation associated with the reverse direction.

Abstract: CRANE WITH OUTBOARD COUNTERWEIGHT CARRIER    Abstract of the Disclosure Disclosed is a crane wherein a trailer-like counterweight carrier has a horizontal motion transmitting connection with a platform which is swivelably mounted on a crane base and which supports the boom and the mast of the crane.  Guy connections between the counterweight carrier and the top of the mast and between the mast and the boom translate forward tilting force that a lifted load imposes upon the boom into lifting force on the counterweight carrier.  A lost motion connection between the counterweight carrier and the platform comprises rigid members.          It allows the carrier to be lifted to a predetermined height above the ground and at that point imposes upon the crane chassis further lift force upon the counterweight carrier, so that the crane base cooperates with the counterweight in resisting forward tilting of the boom under heavy loads.  The lost motion connec-tion requires no adjustment to adapt it for different loads and different inclinations of the boom and mast.

Abstract: EXTERNAL INTERFACE CONTROL CIRCUITRY       FOR MICROCOMPUTER SYSTEMS     Abstract External interface control circuitry is described that couples a microcomputer system (100) to an external device (800).  The control circuitry includes a microcomputer (102), a power switch (108) for applying power to the external device (800) in response to a PSC* signal, bus control (104) for gating interface signals from the microcomputer (102) with a PD* signal for application to the external device (800) and a peripheral interface adapter (106) for producing the PC and PD* signals and coupling the PI* and READY*/IRQ* signals to the microcomputer (102).  A power-up sequence is executed by the microcomputer (102) in response to grounding the PI* signal when the external device (800) is plugged into the microcomputer system (100).  Next, the external device (800) produces a binary zero state of the READY*/IRQ* signal, and in response microcomputer (102) produces a binary one state of the PD* signal and thereafter the PC signal.  The sequence is then completed when the external device (800) returns the READY*/IRQ* signal to the binary one state.  The unique power-up process insures that the external device (800) is only powered when present and protects CMOS devices in the interface control circuitry from being inadvertently destroyed.
