Patent GB-2114714-A (GB)
Title: Flow regulator
Inventor: OWEN WILLIAM GEORGE SIDNEY
IPC: G05D7/01
Filed: 1983-02-07
Abstract: A constant flow valve particularly suitable for use with instantaneous electric water heaters has a fluted core (11) mounted on a spindle (10) which is axially moveable relative to a seating surface. An elastically deformable ring (13) surrounds the core. An annular member (19) is mounted and retained on the spindle at the end of the core adjacent the fluid inlet (23), the outer diameter of said member being such that with the core positioned relative to the elastically deformable ring so as to provide the minimum flow setting of the valve, the annular member controls the actual minimum flow, so that an accurately constructed core is unnecessary. <IMAGE>

Title: Flanged plain bearing and method of making the same
Inventor: DICKSON ERIC WINSTON
IPC: F16C33/14
Filed: 1983-09-02
Abstract: A method of manufacturing a flanged plain bearing from a bearing blank 21 having a bearing backing and a bearing lining of a bearing material. A series of slits 23 are formed in a first region 22 of the blank which is to become a flanged portion 12. The first region is folded to a position in which it is perpendicular to the remainder of the blank and the blank is bent into a semi-cylindrical shape. The first region can be folded prior to the bending or the blank may be bent prior to the folding but in either case, the slits must be formed prior to one of these operations. The resulting bearing comprises a journal portion and a flange portion providing a thrust surface, the flange portion being integral with the journal portion and being made up of a series of discrete tabs 13. <IMAGE>

Title: Tube cutter
Inventor: WOLSONCROFT ALAN
IPC: B23D21/04
Filed: 1984-03-09
Abstract: A tube cutter includes a carriage assembly 18, 20 which is rotatably mounted one body assembly 2 which is mounted on a tube to be cut. A driven gear assembly 24, 26 is secured to the carriage assembly 18, 20. A drive gear system 54 drives the driven gear assembly 24, 26 to rotate the carriage assembly 18, 20 about the tube. The body assembly 2, carriage assembly 18, 20 and driven gear assembly 24 each comprise two readily disconnectable semi-circular parts so that the cutter can be fitted around a tube without disconnecting the ends of the tube. A cutting tool assembly, including a cutting tool bit 32, is mounted on the carriage assembly 18, 20 for rotation about the tube to be cut. This tool bit 32 is advanced towards the tube by a lead screw 36 which is rotated in response to rotation of a star wheel. A small rotation of this star wheel is produced for each revolution of the cutting tool assembly about the tube to be cut. This means that the tool bit advances a small distance towards the tube for each revolution of the cutting tool assembly about the tube to be cut. <IMAGE>

Title: Mixing apparatus
Inventor: GOBERT GERALD
IPC: B01F7/16
Filed: 1984-05-03
Abstract: The apparatus comprises a cylindrical container (2) having an outwardly dished base (4). A shaft (14) extends vertically through the vessel and is supported at one end by an external bearing (16) located on the underside of the base (4) and at the other end by a motorised driving assembly (8). The shaft carries counter-rotating stirrers (20,22) and agitating members (26,30,32) arranged so that when rotated they effect a generally uniform mixing action throughout the container (2). Further rotating stirring or agitating members (24) are located in the lowermost region of the container to effect an additional local mixing action in that region and so prevent the components being mixed to form a solid mass there. An exit orifice (40) is located in the latter region and a scraper (52) mounted on the stirring member (24) wipes over the orifice to assist the discharge through the orifice. <IMAGE>

Title: Pipe coupling-diverter valves
Inventor: MILLS DAVID VICTOR
IPC: F16K11/052
Filed: 1984-08-01
Abstract: A tubular diverter member (9) is pivotally mounted in a housing (1) having an inlet (3) and two outlets (5, 7). The tubular diverter member (9) is pivotally mounted on a cranked arm (11) so that rotation of the cranked arm (11) lifts the lower end of the tubular diverter member (9) out of one outlet (5) and then moves the diverter member (9) over and down into the other outlet member (7). At all times the upper end of the tubular diverter member (9) is located loosely over an inlet tube section (13); the diverter member (9) being a loose fit within each outlet (5, 7). Thus there is no requirement for expensive seals and the overlapping loose fit of the tubular diverter member (9) obviates the necessity for close tolerances. <IMAGE>

Title: Using 8-bit modules in a 16-bit microprocessor system
Inventor: TURLAKOV HRISTO ALEXANDROV
IPC: G06F13/40
Filed: 1985-12-20
Abstract: A problem is the connection of a 16-bit microprocessor system (1) to 8-bit modules (5) so as to enable the performance of byte and word exchange operations and to facilitate the design of the software, by allowing use of instructions not restricted by the bit type of the modules. The problem is solved by a connection method where the 16-bit microprocessor system (1) in the case of word (2-byte) exchange is set in a waiting state during which time two writing or reading operations are performed. This enables the two bytes to be subsequently written in the 8-bit module (5). In word reading the least significant byte is stored in an additional register (7), the second byte is fed directly from the 8-bit module (5), and the 16-bit microprocessor system (1) reads the two bytes (the word) at the end of the second operation. <IMAGE>

Title: Dummy plugs
Inventor: SHORROCK TIMOTHY
IPC: H01R13/44
Filed: 1986-02-05
Abstract: Known dummy plugs are made of an electrically insulating material and merely plug into an electrical socket to cover the terminal holes. However such safety plugs can be pulled out of the socket and thus do not prevent unauthorized use. The present invention provides a dummy plug (1) having at least two elongate pins (7, 9), at least one of which pins (7, 9) is movable to thus secure the plug (1) in the socket. In one example, the pins (7, 9) are pivotal from a parallel ready-for-use position towards each other, by means of a cam arrangement (19, 25). Thus by moving the cam arrangement (19, 25) using a suitable key (33), the pins (7, 9) can be angled relative to each other locking the plug (1) in the socket. In a second example, one of the pins 41 has a free end region of larger cross-section than the majority of the length of the pin. After insertion of the plug in a socket the pin is rotated about its longitudinal axis to prevent removal of the plug. <IMAGE>

Patent GB-2181835-A (GB)
Title: Monitoring device
Inventor: COURT GEOFFREY RUSSELL
IPC: G01B11/06
Filed: 1986-09-30
Abstract: A device for monitoring the position of a surface of a body, as in the monitoring of the thickness of a coating (42) being applied to a cylindrical workpiece (10) by flame spraying, comprises a source of light or other electromagnetic radiation which is projected e.g. via an optic fibre (28) and mirror (21) onto the surface of the piece (10) in a direction inclined to the normal to that surface and there is formed and detected an image of radiation scattered from the surface in a direction inclined to the direction of the incident radiation. A detecting means (24) e.g. a linear C.C.D. array then detects the displacement (y) of the position of the image in a direction substantially perpendicular to the direction in which the scattered radiation is detected arising from displacement (z) of the surface in the direction of the normal. As described the light source is pulsed so that detection occurs at the same spot on the workpiece despite rotation of the latter as the sprayed layer (42) is built up, alternatively the system may detect average layer thickness around the circumference. For cooling and to prevent contamination, air is supplied to the device and flows out of viewing window (36). The system may also be used to measure material removal e.g. in a lathe, or to check turbine blade expansion or surface profiles. <IMAGE>
