Patent GB-2190182-A (GB)
Title: Burner/injector arrangement
Inventor: DUNPHY MALCOLM P
IPC: F23D11/00
Filed: 1987-04-13
Abstract: A burner/injector arrangement for use with oil fired boilers comprises a pair of air suction fans (11,25) arranged in tandem and each coupled to a compressor (20,27) so that air can be blown into the compressor (20,27) to create an axially disposed vortex air flow pattern issuing from each compressor (20,27). A fuel injector head (30) is arranged in-line with the two-stage compressor (20,27) to inject fuel into the centre of the air vortex along the common longitudinal axis and means are provided to cause ignition of the air/fuel mixture. A transfer chamber (22) enclosing arcuate blades (23) is provided between the outlet of the first compression stage (20) and the inlet of the fan (25) of the second compression stage (27) which causes a change in the direction of the pressurized air outflowing from the first compression stage (20) so as to deliver a rotating mass of pressurized air into the fan inlet of the second compression stage (27). <IMAGE>

Title: Rotary actuator
Inventor: CURGENVEN DAVID GEORGE
IPC: F15B15/06
Filed: 1988-01-07
Abstract: A rotary actuator (10) formed as a self-contained unit comprising a housing (12) within which an elongated web (16) is fixedly mounted on a rotatable shaft (14), the shaft (14) extending out of the housing (12, 13). Within the housing (12) opposite end regions of the web (16) are pivotably connected to respective connecting rods (22, 22') which are also pivotally connected to respective pistons (20, 20'). The pistons (20, 20') are movable along respective cylinders (26, 26') formed within the housing (12) under the effect of hydraulic pressure fed to the cylinders (26, 26') via ports (30, 30'). Thus by fixing the housing (12) hydraulic pressure can produce the desired rotation of the shaft (14) and any device connected thereto. In a second embodiment one piston is operated by a spring instead of by hydraulic fluid. <IMAGE>
Patent GB-2200987-A (GB)
Title: Ultraviolet radiation detector
Inventor: MCDONNELL DAMIEN GERALD
IPC: G01J1/58
Filed: 1988-01-11
Abstract: An ultraviolet radiation detector (10) incorporates photoluminescent element of thin section in the form of a sheet (12) of fluorescent material. The sheet (12) has upper and lower surfaces (12A and 12B), and sheet edges together with the lower surface (12B) have reflective coatings (14A and 14B). The upper surface (12A) is overlaid by a UV transmissive, visible non-transmissive filter (16). A light output port (18) is formed through the edge coating (14A), and has a much smaller area than that of the upper surface (12A). UV radiation transmitted by the filter (16) passes through the upper surface (12A) and is partially absorbed in the sheet (12). Unabsorbed UV radiation passes to the lower surface (12B) and its coating (14B) for reflection, and returns for a second transit of the sheet (12) and further absorption. This produces fluorescence at visible wavelengths. A substantial proportion of the fluorescence is guided by internal reflection at the upper and lower sheet surfaces (12A and 12B) to the light output port (18). This provides light concentration because UV radiation is gathered over the area of the upper surface (12A), but luminescence is guided to the much smaller output port area. The light output intensity may be compared with a pre-calibrated graduated colour scale for UV intensity measurement. This provides a UV detector of great simplicity and cheapness. Focussing optics and electronic detectors are not necessary, although the latter may be provided if electronic readout is required.

Patent GB-2208449-A (GB)
Title: Track indicator apparatus
Inventor: BARTRAM CHRISTOPHER
IPC: B61L1/18
Filed: 1988-08-05
Abstract: A railway track indicator system for indicating the absence or presence of a train on sections of track has a plurality of receiver/transmitter units (20, 22) each coupled to the track via a single broadband track-coupler (24) located at the junction between adjacent track sections. Each unit (20, 22) transmits a signal comprising carrier signal bursts having a predetermined pattern of carrier frequencies characteristic of the track section associated with the transmitter, the signal being received by the receiver of the unit coupled to other end of the relevant track section. The carrier frequencies are in the region of 100kHz and the track sections are substantially non-resonant, cross-talk between the sections being largely avoided due to the attenuation of signals of this frequency along the track. This avoids the expense of large tuning inductances in the track-couplers (24) capable of carrying traction currents. <IMAGE>

Title: Artery support insertion instrument
Inventor: WEBBER JOHN STANLEY
IPC: A61F2/82
Filed: 1990-05-11
Abstract: An instrument carries an artery support material section which it then reduces to a suitable diameter so that the whole instrument can be inserted into a patient's artery using a catheter method. The instrument comprises a bobbin in two halves 1, 2 connected by a spring 5 or pair of magnets; two cables 8, 12 pass through the bobbin and operate two umbrella-type gripping mechanisms 10, 14, one on each side of the bobbin. The artery support material passes over the bobbin and gripping mechanisms and is stretched by separating the bobbin halves so that the material reduces in diameter for insertion into the artery. Upon reaching the area of the artery that is requiring support the support material is returned to its original diameter, the instrument closed down to a diameter less than the interior of the artery and the instrument is withdrawn. <IMAGE>

Title: Controlling electromagnetic valve of a fuel pump
Inventor: SIEBERT HANS-JOACHIM
IPC: F02M51/00
Filed: 1991-02-01
Abstract: To control actuation of an electro-magnetic valve (20, Fig 1) of a fuel pump (10) for an internal combustion engine, drive signals for the valve are determined in dependence on markings on an increment wheel (55) mounted on a shaft of the engine, a fuel conveying start WB and end WE being determined by the valve. To determine a drive signal for the valve, Fig. 5c, the markings on the shaft are counted and interpolation, B1 or B2, of shaft position between markings is carried out in dependence on the rotational speed of the shaft. Variations in rotational speed are accurately tracked by determining the speed from the two markings prior to interpolation; the speed is updated throughout the fuel pulse. <IMAGE>

Title: Tubular fitting for use in a drilling string
Inventor: LEE PAUL BERNARD
IPC: E21B21/10
Filed: 1991-06-21
Abstract: A tubular fitting 10 is positioned above a drilling tool coupled with a drill string where in use an increase in fluid pressure acts on the head seal 25 to move the sleeve 16 downwardly so that tail seal 29 seals on sleeve seal 30. When the fluid pressure decreases the spring 26 returns the head seal 25 and sleeve 16 to the upper 'valve open' position allowing mud or drilling fluid to drain out through the ports 28. The apparatus thus operates as a dump valve. The movement of sleeve 16 may also be used to operate a locking mechanism (41) to lock or unlock a tool under differential fluid pressure action. <IMAGE>
