Title: Cover and frame assemblies for manholes or access holes
Inventor: FERNS DEREK
IPC: E02D29/14
Filed: 1986-04-02
Abstract: Components for use in the manufacture of a manhole or access cover and frame assembly comprise L- sectioned elongate frame elements 16, and elongate L-sectioned cover elements 17 which may nest within the frame elements 16. The dimensions of first limbs 18,20 of the two elements are such that, when the elements are nested, the longitudinal free end edge surfaces 22,23 thereof are adjacent and substantially co-planar. The second limb 21 of each cover element is formed, at its free end edge, with a longitudinal flange 33 which overlies the longitudinal free end edge surface of the second limb 19 of the frame element 16 within which it is nested. In a rectangular cover and frame assembly manufactured from such components, the components may be assembled with either their first limbs or their second limbs vertical, depending on functional requirements, the latter arrangement rendering the assembly particularly unobtrusive at floor level. <IMAGE>

Patent GB-2213791-A (GB)
Title: A tubular belt conveyor
Inventor: HASHIMOTO KUNIO
IPC: B65G15/08
Filed: 1987-12-24
Abstract: An endless conveyor comprises first and second rollers (2, 3) spaced apart along the length of the conveyor, and an endless conveyor band or belt (1) engageable in flat form around the rollers (2, 3) and extending between the rollers so as to define a material-conveying path and a return path, the conveyor band being rollable-up into generally tubular form as it moves along at least the material-conveying path. A guiding device (71, 72, 73) is engageable with the band (1) as it leaves one of the rollers (2, 3) in flat form so as to guide the flat band progressively into tubular form. The guiding device comprises a plurality of guide frames (71, 72, 73) spaced apart from each other in a direction away from one roller to the other roller and each having a generally circular array of guide rollers engageable with the conveyor band so as to form it into a tubular shape within the circular array, in which the circular arrays diminish in diameter progressively from one guide frame to another in the direction away from said one roller to the other in order to apply progressive inward deformation of the flat band into the required tubular form. Thus, the diameter of the circular arrays of the guide rollers increase as they approach the respective roller, thereby preventing the conveyor band from slackening, and permitting smooth running to be obtained. <IMAGE>

Title: A spectral filter
Inventor: DAKIN JOHN PHILIP
IPC: G01N21/35
Filed: 1988-06-14
Abstract: A multi-line spectral filter arrangement for detecting a wide variety of gasses comprises a light transmitter such as an optical fibre 4 for transmitting light via a lens 8 to a dispersive element such as a reflective diffraction grating 12, and light from the dispersive element is focussed onto a light detector 6. In a preferred embodiment a spatial filter 14 is disposed in the optical path between the lens and the light detector and a piezo-electric bender 16 moves the optical fibre in a plane perpendicular to the lines of the grating 12 for scanning the spectral filter response to detect selectively different absorption line patterns corresponding to the expected position of absorption lines of a gas to be monitored. Alternatively a detector array with weighted outputs may replace the single detector 6 and spatial filter 14, and other parts of the system may be moved to effect the wavelength scanning. <IMAGE>

Patent GB-2236804-A (GB)
Title: Compound nozzle
Inventor: ROBINS ANTHONY REGINALD
IPC: B05B1/14
Filed: 1989-07-26
Abstract: A compound nozzle consists of a primary passage 22 for conveying a first part of a fluid to be ejected and a secondary passage 23 surrounding the said first passage 22 and communicating with the ambient. The secondary passage 23 is effective to divert a second part of the fluid along a path 26 so as to induce a flow of fluid from the ambient, and is also effective to direct the induced fluid such that in use it encases the first part of the fluid as it leaves the primary passage 22 of the nozzle. The arrangement reduces the noise generated by fluid leaving the nozzle, and may be used in nozzles producing jets for cleaning or cooling, and also in the propulsion of aircraft or boats. In modifications, a shroud may surround part of the induced ambient flow, and the cross-sectional area of the surrounding passage may be variable. <IMAGE>

Title: Device indicating loss of liquid
Inventor: DISON HENRY BURROWS
IPC: G01M3/32
Filed: 1989-12-06
Abstract: A device (14) indicating loss of liquid from a body e.g. a fibrous card (12) is formed from a sheet of paper and has printing in the form of a star (16) on the underside thereof. A window (15) is suitably marked on the front face of the paper to clearly locate the position of the star, together with wordage (17) in the form of an instruction to a user. The device is in contact with the card (12) and the liquid wets it rendering it transparent and making the star visible. When liquid is lost from the card, the device also loses liquid, becoming opaque and resulting in the star no longer being visible. The card is inpregnated with solvent based liquid and gives off vapour useful for preventing paint on brushes etc hardening. <IMAGE>

Title: Jam detecting device
Inventor: NISHIKAWA TOMOYUKI
IPC: G06K15/00
Filed: 1990-11-12
Abstract: A jam detecting device provided in a printer for detecting jam of a continuous stationary web recording medium (FP), has an overhead sensor (53) which does not come into contact with the recording medium when being normally fed in the feed path, but does so when the medium floats up from the food path. If the sensor outputs a signal indicating that the recording medium is in contact with the sensor, it is determined that a jam has occurred. This might occur, for example, due to swelling caused by a jam in a fixing unit (30). Skew sensors (51-51 Fig. 2) and further sensors (50) (52) are such as to be in contact with the medium when normally fed but out of contact when the medium drifts away from the feed path, for example when a loading or trailing end of the medium moves past them. <IMAGE>
