Title: A shroud for a fluid-flow valve
Inventor: BROWN ROY JAMES
IPC: F16K5/06
Filed: 1988-11-30
Abstract: A shroud (42) for a fluid-flow valve which, when fitted to such a valve, provides a lockshield arrangement, has a recess (48) at its upper end the cross-section of which is hexagonal to allow a key of corresponding outer cross-section to engage and rotate the shroud (42), and engagement means (50), e.g. a square section aperture, to enable the shroud (42) to engage, e.g. a square section part (38) of, the stem (28) of such a valve so that rotation of the shroud (42) effects rotation of the valve stem (28), and hence opens or closes the valve, or changes the effective flow-way area of the valve. A shroud cover (44) to prevent unauthorised rotation of the shroud (42) is a snap fit on the shroud and rotatable relative thereto. A screw (52) retains the shroud (42) on the stem (28). <IMAGE>

Title: Power operated stapling machine
Inventor: LIN CHUNG-CHENG
IPC: B25C5/02
Filed: 1989-10-10
Abstract: A DC power operated stapling machine utilizes a micro-switch (12) to control battery power supply to drive a DC motor 3, which rotatively drives, upon actuation of switch 13 by paper to be stapled, a gear wheel (6) by means of power transmission through a gear set 4 and a screw rod (5). As the wheel 6 rotates pins 18, 19 thereon control a contact rod 15 either for operating a striking block 7 to drive a staple from staple receiving slide 21 to staple paper or for ceasing stapling operation. The pins 18, 19 sequentially press rod 15, against the bias of spring 9, to engage a contact switch 12 to cease stapling operation and to release rod 15 to disengage it from switch 12 to allow spring 9 to drive block 7 to drive the staple. Alternatively, rod 15 is spring biased to engage switch 12 and the pins sequentially displace it from switch 12 to drive block 7 and release it to allow reengagement with switch 12 to cease stapling operation. <IMAGE>

Title: Production of flat products
Inventor: WARD ROBERT FRANK
IPC: B22F5/00
Filed: 1992-01-07
Abstract: A process for producing strip products which comprises forming an aqueous slurry of a suspension of metallic particles in a film forming cellulose derivative, depositing a quantity of the slurry onto a support surface, drying the slurry to form a self supporting flat product, removing the dried product from the support surface and roll compacting the same to produce a green strip. The green strip is supported on a moving surface as it travels to and enters a heater in which it is heated in an oxidising atmosphere to a temperature at which substantially all traces of the cellulose derivative are removed. The heated strip is fed while still on the moving support surface to and through a sinter furnace to form a coherent strip of the required composition. <IMAGE>

Patent GB-2253721-A (GB)
Title: Pressure control valve
Inventor: BLUMENDELLER WILHELM
IPC: G05D16/20
Filed: 1992-03-12
Abstract: In a pressure control valve (10) which controls a hydraulic pressure in proportion to a continuously adjustable electrical setpoint signal, the pressure-dependent position changes of a valve cone (19) supported against a measuring spring (21) are detected by a displacement pickup (13) and are used, via a position control loop (42) with control amplifier (39), for driving a proportional magnet (12) which controls the setting of the valve, either by adjustment of a piston (16) which defines a valve seat (18) or by adjusting the closing force of the spring (21) (Fig 2, not shown). The displacement of the valve cone (19) is transmitted via a rod (43) through the magnet (12) to the displacement pickup (13) so that a precise displacement measurement of the measuring spring (21) and thus an accurate and wear-independent pressure control is possible. In the embodiment of Fig. 2, the position of the armature of the magnet (12) may also be detected by the displacement pickup. <IMAGE>

Title: A method of and apparatus for assessing the scratch behaviour of bodies
Inventor: LEWITZ RAINER
IPC: G01N33/38
Filed: 1992-09-29
Abstract: To assess scratch behaviour of bodies, such as glass panes for motor vehicles, at least one scratch mark which extends over a substantially plane area is initially provided in one surface of the body (15) by means of a loadable diamond scratching element (24). After a specified period of time has expired, the ratio of the length of the "closed" scratch relative to the overall length of the scratch mark is determined so as to provide some measure of the scratch stability of the body. To impart the scratch or scratches, a scratching device (10) is used, which includes a carriage (17) movable by means of a stepping motor (31) along a horizontal guide track (18). A support beam (20) is arranged on a holder (19) which is mounted on the carriage (17), and is movable by means of a control drive (22) transversely to the horizontal guide track (18). A diamond scratching element (24) is mounted in a holder (23) at one end of the support beam (20) and by movement of the beam (20) and the carriage (17) can be caused to make one or several parallel scratches in the body (15). <IMAGE>

Title: Control system for continuously-variable transmission
Inventor: SATO KEIJI
IPC: F16H61/02
Filed: 1992-10-09
Abstract: A control system for a belt-type continuously variable transmission of a motor vehicle, having primary and secondary control valves 60, 50 for varying the transmission ratio. The primary control valve receives an electric signal from a control unit to vary a primary hydraulic pressure Pp. The primary control valve produces a primary pressure which causes the transmission to take an intermediate transmission ratio when the electric signal is not transmitted due to a failure such as breakage of a cable. Thus, dangerous situations of the vehicle are prevented, and the vehicle can reliably start in a relatively low speed range of the transmission. <IMAGE>

Title: Auxiliary power unit for motor vehicles
Inventor: SMITH SAMUEL DAVID
IPC: F02B1/04
Filed: 1992-11-06
Abstract: An auxiliary power unit (1) for use when the main engine fails comprises an engine powered by petrol, diesel, gas or electricity located eg in the area of the vehicle boot (4). Mounted on the drive/crank shaft of the power unit is an arm (7) carrying a ground engaging wheel (8) at its free end. The arm can be pivoted under hydraulic action in operation of a control lever (6) in the vehicle passenger compartment to move the arm and wheel into or out of engagement with the ground surface. The auxiliary power unit thus propels the vehicle while the vehicle is under the control of the vehicle steering and braking system. Hazard warning signals may be displayed to other road users when travelling under auxiliary power. <IMAGE>

Title: Tracking apparatus
Inventor: PARSONS TIMOTHY JOHN
IPC: G06T7/20
Filed: 1993-04-29
Abstract: Apparatus suitable for tracking a road vehicle from an aerial platform uses a correlator (5) for processing data received from a thermal imager (1). The apparatus derives a binary template based on points of high curvature (12) in an object to be tracked, which are then binaried (8); the template is then compared with subsequent images by correlator (5). The invention shows a significant reduction in mistracking and drift compared with conventional correlation trackers under the conditions of high density of features similar in nature to the object of interest, such as typifies the imagery obtained from a ground-pointing camera mounted on an aerial platform.   <IMAGE>

Filed: 1993-12-16
Abstract: To improve the reliability of the image or to selectively enhance parts of the image produced by electrical impedance tomography (EIT), also known as applied potential tomography (APT) the electrical signal measurements relating to different parts of the image are made over different periods of time. The manner of variation can be related to the relative positions of drive and receive electrode pairs or to the output signal size, either as theoretically expected or as actually measured e.g. measurements may be taken for a longer period where the signal level is low in regions remote from the drive electrodes D. The invention can be applied to serial or to parallel data collection techniques. <IMAGE>
