Patent GB-2300698-A (GB)
Title: Steam generator
Inventor: HOPPER TIMOTHY GEORGE
IPC: B44C7/02
Filed: 1995-04-25
Abstract: A steam generator has a base 1 in which an electrical heating element 2 is fitted for boiling water in the generator. The base and a lid 3 are welded together. The lid has an opening at which a filling spout 5 extends up. The spout is externally threaded for a filler cap 6. A non-return, flap valve 8 is provided at the opening. Normally, the flap valve is open, so that water can be poured in through the opening when the cap is removed and there is ambient pressure within the generator. If the cap is removed when there is an over-pressure of steam in the generator, the flow of steam up out of the opening closes the flap valve to prevent escape of steam.
Patent GB-2302711-A (GB)
Title: A turbine disc with blade seal plates
Inventor: EVANS NEIL MILNER
IPC: F01D11/00
Filed: 1995-06-26
Abstract: The blades 2 of a turbine disc 1 are held in the axial direction using seal plates 4, which at the same time seal the blade root section 3 against leakage losses. The seal plates 4 are cast in such a manner that they have a directionally solidified crystal structure in the circumferential direction (7)(figure 2). In this way the stress loading of the individual components is reduced and deformation of the seal plates 4 reduced in the circumferential direction (7), whereby the size of the gaps between the seal plates (4) is kept small over the operating lifetime of the turbine.

Title: Valve for dispensing a substance stored under pressure
Inventor: LACOUT FRANCK
IPC: B65D83/14
Filed: 1996-05-10
Abstract: A plastics material valve for dispensing a substance, particularly from an aerosol receptacle. The valve comprises a movable actuator rod (10) and a fixed valve body (9), the actuator rod (10) having a passage (11a, 11b) for the substance to be dispensed. The valve also includes a closure (14) held in the receptacle by the valve body (9) and arranged, with the actuator rod in a first position, to close the passage (11a, 11b). Displacement of the actuator rod (9) from the first position to a second position, in which the passage is opened, enables the substance to be dispensed. A resilient return means for returning the actuator rod to said first position is in the form of a bridge of elastomeric material (27) interconnecting the actuator rod (10) and the valve body (9). The body (9), the actuator rod (10) and the bridge of material (27) are made by a dual-injection moulding technique, the body and the rod being made of a first plastics material and the bridge of material being made of an elastomer, second plastics material. The plastics materials are selected so that said bridge of material is attached to the rod and to the body by local melting of material during moulding.

Title: Regulating the injection quantities of fuel injectors of combustion engines using fuel pressure measurements
Inventor: AUGUSTIN ULRICH
IPC: F02D41/38
Filed: 1998-01-07
Abstract: Regulating the injection quantities of injectors 1-8, having a fluidic connection to a common pressure line 9, in a common-rail injection system of an internal combustion engine. A fuel pump 11, 11' provides fuel at a high static rated pressure in the pressure line. A regulator unit 13 provides control signals for opening and closing the injectors 1-8 with individual injection periods in order to obtain identical injection quantities for each injector. A pressure-measuring device 12, inserted into the pressure line 9, measures the static pressure in the pressure line after each individual injector has closed. Based on the rated pressure before the injection and the pressure differential after the injection, the regulator unit 13 determines the quantity of fuel removed from the pressure line during the individual injection (figure 2). When this injection quantity deviates from a reference value, the regulator unit appropriately changes the injection period of the diagnosed injector. Therefore when there are different throughput rates of the individual injectors, as a result of tolerances or, in particular, from deposits forming over the service life of the internal combustion engine, identical injection quantities are provided.

A free end 16 of the strip portion is accessible in the mouth of the envelope so that the strip may be pulled out of the envelope to allow reading of matter carried thereon. The carrier is the size of a credit card when folded.
