Patent GB-2245691-A (GB)
Title: Liquid fuelled cannon
Inventor: ZIELINSKI ERICH
IPC: F41A1/04
Filed: 1991-03-26
Abstract: A liquid fuelled cannon overcomes disadvantages of the bulk-loading system or the regenerative-piston system in which either the combustion proceeds uncontrollably because the interfaces determining the combustion vary considerably causing major fluctuations in the gas pressure to occur, or large piston masses have to be arrested. The compact combustion of the liquid fuel in a space saving fuel chamber with uniform combustion characteristics is achieved by an axially movable pumping piston 25 inside a fuel chamber 22 with the stroke a of the said piston only corresponding to a certain section of the length 1 for the fuel chamber 22. By means of vanes 32 the fuel chamber 22 is subdivided over the remainder of its length b by into parallel separate chambers (30). In the short stroke a the pumping piston 25 ensures the even ignition of the main charge, while the individual chambers result in a largely non-fluctuating combustion of the main charge. <IMAGE>

Transparent viewing means (31) are either mounted on the rigid outer shell (4) in the wearer's line of sight or can be formed as a viewing window (31) incorporated in a flexible NBC hood (30) or a full face protective helmet.
Patent GB-2267005-A (GB)
Title: Data transmission
Inventor: HAMMOND MICHAEL WILLIAM DAVID
IPC: H02G1/08
Filed: 1992-05-15
Abstract: Data transmission in utility meter reading such as water meter reading is achieved by means of a fibre optic cable 16 disposed between an encoder associated with the water meter 10 and a remote reader 12 within a building. In order to avoid the need for structural alteration to the building, the fibre optic cable 16 passes through a sealed connector into the water pipe 14 at the water meter end of the pipe, and out of another sealed connector at the remote reader end of the pipe. Meter reading data transmission can be achieved either by the encoder generating a serial data stream signal indicative of the meter reading in response to an interrogation signal from the remote reader 12, or by using a light interrupter at the encoder, the remote reader 12 then including a photoemitter and photodetector arrangement. The cable 16 can be installed within the pipe 14 by propelling a soluble member along the pipe under fluid pressure so as to lay a line inside the pipe 14 between the two openings in the pipe, and then pulling the cable 16 through by means of the line. After cable installation, the member will dissolve avoiding the need to remove the member. <IMAGE>

Title: Pressure balanced valve
Inventor: SCHAUERTE BRUNO
IPC: E21B34/04
Filed: 1992-05-28
Abstract: A pressure balanced valve, particularly for deep oil prospection, has a piston (2) and a piston guide (3) displaceable inside a cylindrical valve body (1) which is closed in one extremity. The piston (2) provides the sealing of lateral openings (1a) of the valve body and covers seal rings (10). When the piston (2) is displaced by an external actuation force against the force of a spring (7), it clears the openings (1a) and allows the displacement of the piston guide (3) until a protection nut (6) associated to the piston guide covers the sealing rings (10). <IMAGE>

Title: Photographic Flash Apparatus
Inventor: KOBAYASHI TAKEO
IPC: G03B15/05
Filed: 1993-08-25
Abstract: The apparatus includes means to monitor the voltage VF on a main flash capacitor C1. A high check signal is applied to turn ON a transistor Tr3 to discharge a capacitor C3 so that the minus side of a neon lamp Ne is grounded through a resistor R4 and the transistor Tr3. If the charged voltage VF is more than 270V, the neon lamp Ne is turned ON and the voltage of the resistor becomes VF minus the ON state holding voltage VN of the lamp. When the check signal becomes low, the capacitor C3 charges to turn on a transistor Tr4 so that a line RLS becomes L. The potential on the resistor R4 side of the capacitor C3 increases until the neon lamp turns OFF and the line RLS becomes H. The pulse width of the line RLS is indicative of the charged voltage VR The pulse width is measured by a CPU so as to control exposure in dependence on the charged voltage VF. <IMAGE>

Patent GB-2276138-A (GB)
Title: Packages
Inventor: PALMER CHRISTOPHER
IPC: B65B9/20
Filed: 1992-12-01
Abstract: A package (2) has a top transverse seal (8) which is designed to be opened by separating two portions (4, 6) of sheet material forming the package (2). The seal (8) has a region of weakness (20) intermediate its extremities (22) where the force required to separate the portions (4, 6) of sheet material is substantially less than that required adjacent the extremities (22). The bottom transverse seal (10) defines the profile of the interior of the package (2). The bottom seal (10) is such that there is a gradual transition (26) between each of the package sides (28, 30) and the transverse direction. Thus the product in the package (2) is encouraged to rest on the central region of the bottom seal (10) for easy accessibility. <IMAGE>

Title: Method for varying the triggering point of an automatic braking process in motor vehicles
Inventor: STEINER MANFRED
IPC: B60T13/72
Filed: 1994-11-01
Abstract: In a motor vehicle, breaking occurs automatically if the speed of actuation of a brake pedal exceeds a threshold value, and that value can be varied within a range in dependance on a fixed threshold value (vF) and the state of a driver operate control device (1). This range is selected in such a way that the effective threshold value cannot be reduced to the extent that the automatic braking process is triggered at actuation speeds of the brake pedal which are normal for travel mode, and cannot be increased to the extent that it is impossible for the triggering criterion for the automatic braking process to be fulfilled. <IMAGE>

IPC: G03F1/00
Filed: 1995-09-07
Abstract: A phase shift mask has a light screen pattern (2) formed on a transparent substrate (1) to define a plurality of lines and spaces. The light screen pattern (2) is partly covered with upper (3) and lower (3') phase shift patterns whose line spacing is wider than that of the lines of the light screen pattern (2) whereby the overlap between the patterns (2; 3, 3') varies and a vernier pattern is defined. Pattern (3) has a phase shift of 180 DEG  whereas pattern 3' has a phase shift of 90 DEG . The resultant overlapping pattern can be detected by the naked eye or with a camera. This enables the degree of overlap to be accurately examined during wafer processing, whereby the product yield and the reliability are much improved. In an alternative arrangement, a phase shift pattern is formed as a grid within a rectangular film pattern on a substrate (Fig 5 not shown). <IMAGE>

Title: Power supply for a transponder
Inventor: NOTO HIROYUKI
IPC: H02J17/00
Filed: 1996-07-11
Abstract: A power supply 3 for a response circuit 2 of a transponder generates DC power from received electromagnetic energy and includes a capacitor 7 charged from a rectifier diode 5 which has a characteristic such that its reverse resistance against a reverse current directed from its n region to its p region is lower than its forward resistance against a forward current from the p region to the n region. The diode 5 is thus connected reversely compared to a conventional diode, its anode being connected to the positive plate of capacitor 7. The arrangement allows the transponder to remain functional even when the received electromagnetic energy is weak. The required characteristic for diode 5 can be implemented by the avalanche or tunnel effect. The diode 5 may be formed from a compound semiconductor or an organic semiconductor. The electromagnetic energy may be received by an antenna 1, or the transponder may be coupled to an interrogator by electromagnetic coupling, electromagnetic induction or microwave. A limiter 8 formed by ordinary diodes 8a, 8b may be provided to limit the voltage applied to the diode 5. A full wave rectifier arrangement may be provided using two capacitors and two diodes of the defined characteristic (Fig.5), or using a bridge rectifier and two receiving antennas (Fig.6), or a voltage multiplier may be provided (Figs.7,8).
