Patent EP-0463594-A1 (EP)
Inventor: ISHIGAMI MOTOHIRO JAPAN AVIATI
IPC: G01C19/02
Filed: 1991-06-24
Abstract: In a fiber optic gyro, a clockwise propagating light ray and a counterclockwise propagating light ray propagate in an optical fiber coil (14) in a time of  T , and are given a bias phase modulation signal (BPM) by a phase modulator (16) connected at an end of said optical fiber coil, in such a manner that a phase shift increasing stepwise by π/2 radian every time interval T is applied n steps and then a phase shift decreasing stepwise by π/2 radian every time interval T is applied n steps, to the phase modulator. A signal generator (26) generates a bias phase modulation signal every time interval T according to an oscillation frequency of a voltage controlled oscillator (24). An interference light beam of said clockwise and counterclockwise propagating light rays is converted to an electric signal by an opto-electric converter (17) and, if the time interval T does not coincide with a propagation time, a positive- or negative-going pulse is created in an output of the opto-electric converter during a period for the bias phase modulation signal to increase or decrease. Such a positive- or negative-going pulse is detected by a pulse detector (27) and, based on a detected result, an oscillation frequency of the voltage controlled oscillator is controlled so that said pulses no longer occur.

Abstract: On the rear side of the front panel (1) of an electronic equipment, at each lateral end which overlaps an edge of an aperture (3) into which the electronic equipment is being inserted, bushings (5) having rearwardly extending catch members (6) are fastened to the rear of the front panel by screws (12). The bushings are of resilient synthetic plastic. The catch members are disposed around a continuation of the central bore of the bushing. Stepped bores (14) are provided in the wall portion overlapped by the front panel. When the bushings are inserted into these stepped bores the catch members are first deflected inwards and then, as they reach their final position, spring outwards and catch against the step (16) of the bore (14). Mating projections (9) and openings (10) lock each bushing against rotation as it is screwed on to the front panel (1). Between the catch prongs there are sector cavities (13) for accepting a mating projection in the bore through the wall (2), so as to hold the bushing against rotation when the front panel is removed for repair or replacement after releasing the screws (12). As a result the bushings will be in correct position or refastening the front panel.

Abstract: When using a laser programmable fuse, a circuit should be 100% stable both before + after the fuse is blown. So far no CMOS circuit can be 100% stable without drawing a constant current. With the "Master fuse Enable" scheme one fuse circuit (master fuse) draws current while disabling all other fuse circuits on-chip. Thus giving 100% stability + reducing power consumption on a chip where no fusing has been done. If, however, one wished to use the rest of the fuses, then the master fuse is blown + all fuse circuits now become active and draw current.

Abstract: A high-density circuit substrate is housed in cassettes 52,54 which seal out deleterious contaminants to the substrate during processing, storage and transportation, thereby obviating necessity for clean-room environments. Substrate material is fed into and out of the cassette through a sealing aperture defined by and disposed through the housing wall. In use, a first feed cassette is releasably attached to a substrate processing apparatus which feeds raw substrate material, by means of a drive bushing on the spool, into the apparatus for punching, dielectric application, and the like. A second take-up cassette returns the thus-processed substrate into the cassette, again by means of rotation of the drive bushing, for storage and subsequent further manufacturing operations, wherein the take-up cassette is detached from the processing apparatus. The opposing inner faces of the housing are provided with symmetrical opposing spiraling grooves. When the substrate material is introduced into or pulled from the cassette, its edges travel in respective ones of these grooves. In this manner, the coil is maintained within the housing with a minute spatial separation between layers in the radial direction.

Abstract: The system enables data from analogue or state sensors S1 to S16, four of which may be direct frequency sensors, located in a ZONE 0 (1) environment, to be transmitted by a master transmitter 10 via a fibre optic data link 16 to a master receiver 14. The master receiver is located in a safe environment. The master transmitter comprises a power restrictor unit 18 which has for each data channel a power supply and also a power supply for the printed circuit-board (pcb) of the master transmitter. The master transmitter is located in a ZONE 1 environment. The analogue or state data are voltages which are converted by voltage-to-frequency converters mounted on the pcb and passed to the multiplexer of the master transmitter. The multiplexer feeds the fibre optic link and a demultiplexer at the master receiver reproduces the frequencies. The master receiver re-converts the frequencies to voltage signals.

Abstract: C₅ and C₆ hydrocarbons are isomerized in a process that combines a deisohexanizer with a PSA separation section to provide a product stream comprising highly branched hydrocarbons such as methylbutane and dimethylbutane. The process combines a methylpentane and normal hexane recycle stream, a normal pentane recycle stream and at least a portion of the C₅ and C₆ hydrocarbons of the fresh feedstream to provide a combined feedstream that is charged to an isomerization zone. The effluent from the isomerization zone is stabilized and passed to a deisohexanizer. A sidecut stream carries the methylpentane and normal hexane recycle stream from the deisohexanizer. Hydrocarbons having a higher boiling point than the sidecut stream are withdrawn as a bottoms stream from the deisohexanizer. An overhead carries normal pentane, methylbutane and dimethylbutanes to the PSA separation section. An extract stream is recovered as the normal pentane recycle stream. The raffinate from the PSA provides a high octane isomerate stream comprising mainly methylpentane and dimethylbutanes.

Title: Abrasive throwing wheel assemblies.
Inventor: MACMILLAN WILLIAM ROBINSON
IPC: B24C5/06
Filed: 1991-07-02
Abstract: An abstract throwing wheel assembly comprises a throwing wheel having parallel annular side plates (29) joined by spacers with the facing surfaces of the side plates having angularly-spaced registering throwing blade locating slots (30) and throwing blades (20) with lateral rails or edges (22) for location in the slots. The side wheels slots are wider than is customary and contain central radially-extending projections (30c). The lateral rails or edges of the throwing blades are grooved (28) from the tips inwardly for at least part of their lengths. The throwing blades are located by interengagement between the sidewall projects and the rail or edge grooves of the blades. This reduces the surface contact between the blades and the side plates with consequent reduction in the accumulation of jamming abrasive during use. Throwing blade removal is thus facilitated. The wider slots remove the narrow radial flow of high velocity abrasive or shot between the slot walls and throwing blade side rails or edges which is customary thus reducing side plate, especially side plate rim, wear.

Abstract: The invention relates to a bearing assembly for a transmission shaft (10), such as, for example, a differential drive shaft with bevel pinion (12) of a vehicle transmission, exposed to bending forces and accepting axial forces. The bearing assembly consists of at least one radial cylindrical roller bearing (18) and two thrust bearings. The inner bearing race (16) of the radial cylindrical roller bearing (18) is supported radially and in an axial direction against the shaft (10). The thrust bearings are arranged on both sides of a bearing housing (40) which can be secured on the transmission case (48) and are supported against the said housing. The thrust bearing which faces the radial cylindrical roller bearing (18) is supported in the said direction against the inner bearing race (16) of the radial cylindrical roller bearing (18). The radial cylindrical roller bearing (18) and the thrust bearings are furthermore fixed against axial displacement on the shaft (10). For a compact design of the bearing assembly which takes up little installation space and contains bearings which are simple to manufacture, it is proposed to use cylindrical roller thrust bearings (22, 24) as thrust bearings and to design the flange-like bearing housing (40) and/or its fixing on the transmission case (48) in such a way that, when the shaft bends, the regions of the bearing housing (40) against which the cylindrical roller thrust bearings (22, 24) are supported adapt to the oblique position of the transmission shaft (10). For this purpose, it is both possible for the bearing housing (40) to be fixed to the transmission case (48) by anti-fatigue bolts (50) yielding to axial forces and for the bearing housing (40) to have areas of varying stiffness in the circumferential direction.
