Patent GB-2080583-A (GB)
Title: Cycle counter for microprocessor integrated circuit
IPC: H03K3/288
Filed: 1981-06-12
Abstract: A microprocessor integrated circuit design has improved partitioning between integrated injection logic (I<2>L) and transistor-transistor logic (T<2>L) in the integrated circuit. An information bus structure incorporating a bidirectional input and output buffer and a bidirectional input and output multiplexer minimizes the number of internal bus lines in the integrated circuit. An improved T<2>L-I<2>L interface circuit and structure supplies a T<2>L input to a plurality of I<2>L input stages, each having a restricted cross-sectional area resistor element in the base of an I<2>L input transistor. A storage register in the integrated circuit has a multiplexer portion provided at each flip-flop circuit of the register. A high speed feed forward flip-flop circuit is employed in registers of the integrated circuit where speed is critical. An improved voltage regulator and current source combination in a programmable logic array (PLA) reduces PLA temperature sensitivity. A pair of I<2>L clocking pulse input transistors in a T<2>L master-slave circuit avoids capacitive coupling problems and allows the master-slave circuit to operate over a much wider temperature range. A cycle counter for the microprocessor integrated circuit implemented as an improved ripple down counter requires a minimum number of gates while avoiding significant delay in operation. <IMAGE>

Title: Vertical filter system
Inventor: ARVANITAKIS KOSTAS S
IPC: B01D33/17
Filed: 1982-12-31
Abstract: A filtration system, especially for edible oils, utilizing a plurality of coaxial, vertically disposed, hollow disc filter elements for clarifying a liquid passed therethrough. Upon the accumulation of a predetermined amount of materials on or in the filter cake, the filter chamber is sealed and the contents drained creating a pressure differential across the filter elements to maintain the integrity of the filter cake. The chamber is then positively pressurized with a gas to dry the expended filter cake on the filter septum prior to its removal and conveyance from the chamber. The chamber is filled with liquid and the filter septum scrubbed to remove any residual materials therefrom. Filter aid material is added to the liquid in the chamber and the liquid circulated through the filtration system in a closed loop at a flow rate sufficient to maintain the integrity of the filter cake so formed until it has removed a sufficient amount of accumulants from the influent to create a pressure differential thereacross which will maintain its integrity on the filter septum at the influent flow rate.

Patent GB-2126712-A (GB)
Title: Surface flaw inspection apparatus for a convex body
Inventor: HAJIME YOSHIDA
IPC: G01N21/952
Filed: 1983-06-08
Abstract: The apparatus is suitable for inspecting a body 1 having a highly reflective convex surface 2. The apparatus includes a light source 3 for irradiating the convex surface, an image sensor 4 such as a television camera, for receiving the light reflected from the convex surface and for producing a corresponding electrical signal, and inspection means 6 responsive to the electrical signal to determine whether or not a flaw is present on the convex surface. A projection screen 7 is located in a light path which extends from the light source to the convex surface and from the convex surface to the image sensor. The image sensor picks up the image formed on the projection screen. The apparatus advantageously avoids picking up an image of either the light source, or of the image sensor (e.g. the lens system of the television camera) and it enables positive, highly accurate and automatic inspection of an area of the convex surface to be made to detect surface flaws such as scratches. <IMAGE>

Patent GB-2160950-A (GB)
Title: Hydraulic damper valves
Inventor: AGNEW JAMES MALCOLM
IPC: F16K47/00
Filed: 1984-06-26
Abstract: A damper valve for smoothing out pressure pulses in a hydraulic line has an inlet port (2) through which fluid enters and forces hollow damper piston (4) to retreat, so causing fluid between piston (4) and end cap (16) to be forced slowly into outlet port (5,6) through cross-bored holes (13,14). When piston has retreated far enough from its seating at the end of inlet port (2) fluid flows direct from inlet port (2) via bore (3) to the outlet port (5,6). When flow ceases a coil spring between the piston (4) and end cap (16) returns the piston to its seating in readiness for the next pulse. The valve may be used in cyclic hydraulic circuits, e.g. in mining equipment. <IMAGE>
