Title: Automatic picture taking machine
Inventor: WAIN JOHN LAURENCE
IPC: H04N7/18
Filed: 1991-10-25
Abstract: An automatic picture taking system has a housing which may be in the form of a booth. The housing contains a video camera (20) and is arranged to produce a video picture of a subject in a picture taking zone (3). The video picture can be converted to a print e.g. using a digital thermal colour printer (24, 25). The video picture is stored in memory and can be processed to give a desired composition prior to printing. The picture may consist of the image of the subject which is separated from the background using chroma keying and which is then combined with a selected electronically pre-stored background or foreground.

Title: Diverter valve
Inventor: BICKERSTAFFE BRIAN DOUGLAS
IPC: F16K11/087
Filed: 1991-11-29
Abstract: A diverter valve, has a body containing a ball valve member in which a main through bore in the ball applies no significant additional restriction to fluid flow than that imposed by the inlet and outlet ports 5. When the valve is rotated through 90 DEG  the through flow is blocked. The ball is provided with two additional holes 10, 11 positioned so that they are blocked when the valve is in its normal open position (fig 1, not shown) and are opened to the supply flow and to an alternative outlet port 12 when the valve is operated. This allows the flow to be diverted to the alternative outlet port. <IMAGE>

Patent GB-2252635-A (GB)
Title: Improvements in or relating to a method and apparatus for measuring shear force
Inventor: HEWIT JAMES ROBERT
IPC: G01L1/24
Filed: 1992-02-17
Abstract: Method and apparatus for measuring the shear force acting over a first surface (4a, 27) by reason of its engagement with a second surface (3) presented by a sheet-form member (1). The second surface is formed with projections (4), the tips (6) of which deflect, in a direction parallel to the plane of the sheet, when subjected to the force. Recording means (7) record the displacement of the tips, and equipment (9) computes the magnitude and the direction of the shear force by reference to that displacement. The specification particularly describes the application of the invention to the measurement of shear forces acting upon a human foot, and to mechanical fingers used to grip components in the course of a robotic assembly process.

Title: Temporary building of interlocking panels
Inventor: SMITH BRAMLEY ALEXANDER
IPC: E04H9/02
Filed: 1992-07-01
Abstract: A system of fixing panel or panel assemblies to constitute a temporary, collapsible or other structure whereby horizontal courses of panels are fixed as in a brickwork bond with each successive course displaced laterally.

Title: Vehicle tracking adjustment.
Inventor: GRIFFITHS PAUL JOHN
IPC: B62D27/06
Filed: 1992-07-15
Abstract: Apparatus for effecting tracking adjustment comprises a member 30 which secures to a vehicle and contains a slot 34 arranged to extend longitudinally of the vehicle and engaged by a spigot (41, Fig. 3) of a bush 37 through which an axle mounting member (36) extends, and which is rotatable in and movable along the slot. The spigot (41) is a smaller diameter portion of the bush, there being a larger diameter portion (42, Fig. 3) the periphery of which is eccentric to the spigot and is disposed between opposed abutments 44, 45 on the member 30 which constrain that portion from moving lengthwise of the slot. Rotation of the larger diameter portion 42 causes the spigot 41, and thereby the axle mounting member, to move along the slot for tracking adjustment. The bush 37 can be secured to the member 30 to retain it in any adjustment portion of the axle mounting member along the slot 34. The member 30 may be a replacement bracket for a, or be a modified, bracket of an existing vehicle suspension and axle assembly. <IMAGE>

Title: Atomising devices and methods
Inventor: DUNNE STEPHEN TERENCE
IPC: A61M11/02
Filed: 1992-07-20
Abstract: A metered dose inhaler comprises a piston (3) which is mounted in a cavity (2) within a body (1), and is urged by a pre-loaded spring (6) into a reduced cross-section pressure chamber (4). The piston (3) may be loaded by means of an actuating rod (31) having a handle (32), and may be latched in a loaded position by a latching means (33). A liquid drug (e.g. in aqueous solution) is contained in a collapsible bag (10). Metered quantities of the drug are successively presented in the pressure chamber (4), and then subjected to a sudden and great increase in pressure, to eject the liquid drug through an atomising head (22), to reduce it to a fine atomised spray of small mean particle size - for example, less than 30 micrometres. Non-return valves (13 and 23) control the flow of liquid through the device. The sudden pressure pulse is caused by releasing the spring loaded piston (3), upon depressing an actuating button (35) connected to the latching means (33). <IMAGE>

Title: Surface controlled annulus safety system for well bores
Inventor: HINES CRAIG D
IPC: E21B34/10
Filed: 1993-07-19
Abstract: A safety system for use in a well having annulus fluid flow includes a surface controlled subsurface safety valve (40) in the form of an annulus safety valve. The valve has a valve closure member (60), and a small diameter offset piston actuator (70) to move the valve closure member in response to control fluid pressure conducted from the well surface to its open position which allows annulus fluid flow.

Title: Locking mechanism for a multi-disc player
Inventor: KUROSU TADAO
IPC: G11B17/22
Filed: 1994-04-18
Abstract: A disc recording/reproducing apparatus includes a recording/reproducing section, a disc tray 2, a driving mechanism, a rotary table 3, a lock mechanism for the disc tray and a suppression mechanism. The recording/reproducing mechanism is provided in a main body of the apparatus for recording/reproducing information signals on or from the disc. The disc tray 2 may be moved between a position facing the recording/reproducing section in the main body of the apparatus and an unloading position outside of the main body of the apparatus. The driving mechanism causes the disc tray to be moved between the loading position and the unloading position. The rotary table 3 is rotatable mounted on the disc tray and has plural disc-setting sections 53, 54 extending radially from the center of rotation. The rotary table 3 is rotated relative to the disc tray for selectively locating one of the plural disc setting sections at a position of facing the recording/reproducing section. The lock mechanism of the rotary table obstructs the rotation of the rotary table when the disc tray is not located at the loading position or at the unloading position. The lock mechanism also is actuated by the driving mechanism in order to obstruct the movement of the disc tray and is similarly driven by the driving mechanism when the disc tray reaches the unloading position in order to obstruct the movement of the disc tray. The suppression mechanism inhibits oscillatory movements of the disc tray at the loading or unloading position of the disc tray. <IMAGE>

Title: Pumping systems for liquids
Inventor: GRAY KENNETH
IPC: F03G6/00
Filed: 1994-06-04
Abstract: A system 1 for pumping water from a source 2 to a tank 3 comprises a solar panel 6, a pumping chamber 10 of variable volume having an inlet and outlet duct 8 and bladder 9 in a pivotally-mounted pressure vessel 7. The panel 6 employs hexane as a working fluid and is connected to pressure vessel 7 and a condenser 17 tiltable therewith. When hexane is vapourised in the panel 6 it causes bladder 9 to move from its Fig. 3 position to its Fig. 1 position expelling water from chamber 10 via the duct 8 to reservoir 31, counterweight 56 then causing tilting of the vessel 7 and condenser 17 and operation of valves 35 and 45. Should little or no water be drawn up duct 20 the pressure vessel 7, influenced by the counterweight 56, will remain in the tilt attitude shown. This acts as a safety means since the condenser 17 retains sufficient hexane as liquid to leave the panel 6 substantially empty of liquid. The system 1 may be used as a master pumping system to operate a slave pumping system (60, Figs. 4, 5). <IMAGE>
