Title: Fluid delivery systems
Inventor: SKYE DAVID ALBERT
IPC: F16L55/04
Filed: 1995-08-02
Abstract: A device (130) for damping fluid flow from a pump (FIG 1) having a pulsed output comprises a central pipe (132) located inside tubing (134) having elastic walls and sealed at ends (136, 138). Central pipe (132) has an inlet (140) and an outlet (142) and is blocked at its centre by barrier (144) to divide the pipe (132) into two portions, an inlet portion (146) and an outlet portion (148). Holes (150, 152) are formed in both the inlet portion (146) and the outlet portion (148), and the sets of holes are not aligned with one another. This forms a tortuous path, as shown by the dotted line, for the fluid passing through the device (130) to a flow sensor (196) (FIG 7) in a photographic solution supply system.The pump comprises an oscillating slug mounted on two bellows.The slug is operated by a coil and contains a double flap valve.Other forms of damper are disclosed (FIGS 2,5 and 6).
Patent GB-2299642-A (GB)
Title: Clutch actuator having wear sensor means
Inventor: FRIEDRICH ERICH
IPC: F16D25/12
Filed: 1996-03-19
Abstract: An actuating device for a friction clutch has a piston 3 slidably mounted in a cylinder 2 and an actuating rod 4 for operating the clutch 2. In order to detect the disengaged state of the clutch a sensor 8 (eg potentiometer) comprises a rod 7, coupled to the piston 3, which extends inside a casing 9. The rod 7 moves axially with the piston 3 until abutment 10 strikes the end wall of the casing 9 where the voltage from the potentiometer is, for example, 5 volts which indicates full engagement. As a result of increasing wear the piston 3 is displaced in the direction of arrow V, this causes the abutment 10 to contact base 11 of casing 9, thereby axially displacing casing 9 with respect to housing 12. When this displacement is at the maximum permissible, ie maximum clutch wear, a detector 18 detects the casing 9 and makes it known via signal or display device. The casing slides axially by means of spring rings 13. After the clutch disc has been replaced, the first pressure loading results in the abutment 10 pulling the casing 9 back to its original position. The displacement may be continually monitored by employing a suitable measuring element, instead of detector 18.

Title: Determination of fluid quantity from density measurements
Inventor: DOE STEVEN CHARLES
IPC: G01N9/00
Filed: 1997-01-06
Abstract: An ultrasonic fuel-gauging system has a tank 1 with several ultrasonic probes 2,3,4 each having a number of reflectors (14-21, fig. 2) spaced along their length. Densitometer 7, such as a vibrating cylinder densitometer, is located at the bottom of the tank and provides an output to a control unit 10 representative of the fuel density at that location. Control unit 10 calculates the speed of sound reflected from the reflector (14, fig. 2) closest the densitometer 7 and uses this and the density measurement to calculate a fuel type constant. The density of fuel at different heights is calculated from the fuel type constant and speed of sound measurements from other reflectors. The control unit calculates a weighted density and from this, along with fuel height position measurements and knowledge of the shape of the tank, the fuel mass is calculated and output to display 11.

IPC: F04B53/14
Filed: 1997-01-23
Abstract: A piston rod assembly has a release link connector (12) coupled to a cross head extension rod (10) and a piston link (11). The connector allows quick release of the assembly and includes one or more tension links (15, 20), one at least on which does not extend or protrude beyond the axial limit of the ends of the body of the connector (12). Tension link (15) is rotatable to allow the pin apertures to be aligned for insertion of pin (25). To assemble the link pressure is applied to space (22) so that the pistons (16) (21) are forced apart a sufficient amount to align the apertures and allow the pins (25) to be inserted. When the pressure in space (22) is released the pins are put in shear by springs (23).

Title: Light beam spreader
Inventor: CASSARLY WILLIAM JAMES
IPC: F21S8/12
Filed: 1996-01-24
Abstract: A beam spreading device 12 for use with a centralized lighting system and which can be applied to emergency vehicle lighting applications achieves a beam pattern light output which is essentially continuous over an output range of plus and minus 45 degrees from a center point. The beam pattern light output is different in two orthogonal axis and spread in the horizontal direction. The beam spreading device is disk shaped and has at least one non-curved surface which mixes the light travelling therethrough so as to achieve the continuous light output. Side wall surfaces of the beam spreading device provide for total internal reflectance properties. A color wheel 18 can be interposed between the output of optical fibers 16 which transmit the light from the centralized light source to the necessary remote location, and the beam spreading device. The color wheel provides the ability to generate different color light outputs from a single light source. One side wall portion may be curved to enable significant packaging depth advantages.

Title: Controlling exhaust gas return rate in an internal combustion engine
Inventor: ENGL MAX
IPC: F01L9/20
Filed: 1998-06-29
Abstract: EGR rate is controlled not only by signal EGRV_SP acting on an exhaust gas return valve but also by signal THR_SP acting on the throttle valve in the air intake which affects the inlet gas partial pressure downstream of both valves. Torque requirement TQI_REQ is based at least on accelerator pedal value PV and engine speed N at block B1 and a desired EGR return rate EGRR_SP is established therefrom at block B2. Controllers 6 and 62 use this desired rate to determine EGR and throttle valve reductions ARED_EGRV and ARED_THR. These are regulated by regulators 63, 64 based on actual value of the EGR rate EGRR_AV derived by observer B3 from sensed engine conditions N to TEG and block B4 and finally signals EGRV_SP and THR_SP are generated via blocks B8, B9. Blocks B1, B2, B8, B9 can comprise engine maps and block B3 a model of the EGR and intake sections.

IPC: H02H7/093
Filed: 1998-09-29
Abstract: The invention relates to a method and a circuit arrangement for the detection and stopping of a blocked or overloaded, permanently excited direct current motor. After the starting of the motor (M) by way of a motor relay (MR) the stopping of the motor (M) takes place by way of the motor relay (MR) after a defined starting time (Tr). At the terminals of the motor (M) a generator voltage (UG) or back EMF is measured and is compared with a defined threshold value (Uref). If the generator voltage (UG) exceeds the threshold value (Uref) the motor (M) is started again. A value above the threshold is indicative of the motor running above an expected speed.

Title: Repairing polyethylene pipes
Inventor: BAILEY MICHAEL KEITH
IPC: F16L55/168
Filed: 1998-11-12
Abstract: A damaged polyethylene gas pipe is repaired in two stages. Initially, a reinforced laminated adhesive patch (15; figure 2) is attached to the live gas leaking pipe to form a temporary pre-seal. After that a fabric mould 6 is wrapped and secured around the pipe, preferably using straps 8 and a Velcro (RTM) and/or zipper fastening 9, the fabric mould 6 being filled with a polyurethane sealant via neck 10. Pressure is applied to the polyurethane sealant using a wind down key 11 so that gas cannot escape from the pipe. The polyurethane sealant preferably adheres to both the laminated adhesive patch, which has been abraded to aid bonding, and the polyethylene pipe surface. In addition to sealing a damaged pipe, this method may also be used to seal polyethylene electrofusion fittings, connection tees, valves and any defects in butt fusion welds.
