Title: A printer having a cutting device wherein the cutting device may be coupled to and decoupled from a printhead carriage
Inventor: SANPEI TAKAAKI
IPC: B41J11/70
Filed: 1995-11-29
Abstract: A printer (10) includes a printhead (5) mounted on a carriage (1) and a cutting device (2) which is located outside the range of movement of the printhead (5) for printing. The carriage (1) is not coupled to the cutter device (2) while the carriage (1) is moved for printing, coupling between the carriage (1) and the cutter device (2) for cutting a printing paper (P) is established by a coupling mechanism (3), e.g. a hook member (31) and a protrusion member (32). Upon establishment of the coupling, the cutter device (2) moves together with the carriage (1) to cut the printing paper (P). After the cutting is completed, the coupling mechanism (3) decouples the cutter drive (2) from the carriage (1). The printing carriage is not unnecessarily burdened with the weight and inertia of the cutter device. <IMAGE>

Title: Method and apparatus for the remote control and monitoring of production wells
Inventor: TUBEL PAULO
IPC: E21B47/01
Filed: 1996-02-09
Abstract: A system adapted for controlling and/or monitoring a plurality of production wells from a remote location is provided. This system is capable of controlling and/or monitoring: (1) a plurality or zones in a single production well; (2) a plurality of zones/wells in a single location (e.g. a single platform); or (3) a plurality of zones/wells located at a plurality of locations (e.g. multiple platforms). The multizone and/or multiwell control system of this invention is composed of multiple downhole electronically controlled electromecanical devices and multiple computer based surface systems operated from multiple locations. Important functions for these systems include the ability to predict the future flow profile of multiple wells and to monitor and control the fluid or gas flow from either the formation into the wellbore, or from the wellbore to the surface. The control system of this invention is also capable of receiving and transmitting data from multiple remote locations such as inside the borehole, to or from other platforms, or from a location away from any well site. The system further provides the possibility of communication between plural zones in a single well or between the zones in a single well or between the zones of different wells, the communication taking place between downhole telemetry devices.

Title: Explosive grenade
Inventor: SCHLUTER KLAUS
IPC: F42B12/32
Filed: 1998-02-19
Abstract: An explosive grenade (12) for defending against an approaching KE penetrator (10) has a number of individual charges (L1, L2, ...) which are connected to associated igniting devices (Z1, Z2, ...) for ignition staggered in time. The individual charges (L1, L2, ...) are dimensioned in such a way that their pressure wave (18) acting on the tail unit (16) of the penetrator (10) to be combated causes the penetrator (10) to be deflected (20). The same effect, that is to say deflection of the KE penetrator (10), can be achieved if the explosive grenade (12) has an explosive charge which reacts with a deflagration effect and which acts on the tail unit (16) of the penetrator (10) to be combated.

Title: Supporting the actuator of an electronically controlled throttle valve for i.c. engines
Inventor: SATO HISAAKI
IPC: F02D9/10
Filed: 1998-03-12
Abstract: The output end 2A of the actuator, eg electric motor 2, is supported in throttle body 1A by fixing a base plate 7 to a flange 1B of the body 1A with a bolt 6. The opposite end 2B of the motor 2 has a cylindrical projection 2C which is supported radially in part 1C of the body 1A by an elastic body, eg an O-ring 9 which may backed up by a ring 10 to prevent torsion and other movement of the O-ring 9. Alternatively, a flat-section elastic ring (9A, fig.3) may be used. In a further modification, the elastic member is a coil spring (11, fig.4), solid or hollow body or wave-washer located axially between the end of the projection 2C of motor 2 and a recess in the end wall of the body part 1C. The radial and axial elastic supports may be combined. The elastic support of the non-output end of the motor 2 means that it is not necessary to provide a heavy wall thickness of the flange 1 B or of the body 1A; weight, size and cost can thus be reduced. Furthermore, a high-precision fit to the transfer gear wheel 3 is not required, reducing assembly costs.

Title: Storage bin
Inventor: BOX STEPHEN FREDERICK
IPC: B65D88/26
Filed: 1998-04-20
Abstract: A storage bin, for example for flour, wheat and so on, comprises a number of corners similar to the one shown in figure 5. Typically, there are four corners. Adjacent wall members (50, 52) are provided with a respective partial fillet (60, 63). In the case of a four-sided storage bin these fillets will preferably have been at an angle of 45‹ to the adjacent wall but other angles are possible. The partial fillets (60, 63) are joined by a backing plate (71) to which the fillets are rivetted (90, 92, 90', 92', 90", 92"). A weld (100) is provided between the partial fillets (60, 63). For larger storage bins, which are assembled on site, the weld (100) will comprises an on-site weld which will generally need to subsequently ground to meet hygiene requirements. In smaller versions of the bin, the weld can be a shop-laid weld which requires no subsequent grinding. The completed bin, therefore, has no crevices or closed voids in which infestation and breeding of unwanted organisms can occur.

Title: A method of moulding and a moulding formed thereby
Inventor: SMITH GORDON FREDERICK
IPC: B29C45/16
Filed: 1998-08-18
Abstract: The method involves providing a thermosetting granular plastics material which is heated to a plastics condition to form a plastics coating material 23 and injected into a mould. A substrate mixture 24 comprising automotive shredder residue and a thermosetting granular plastics material is then injected to spread the coating material 23 over surfaces of the mould so as to envelope the mixture 24. A moulding is thus produced having a substrate including automotive shredder residue and a coating. The automotive shredder residue is sealed within the moulding. This method provides an alternative route for the disposal of automotive shredder residue. The plastics materials may be thermoplastics or elastomers.

Title: Operation of a vehicle alternator
Inventor: KEATES JOHN
IPC: H02P9/30
Filed: 1999-02-15
Abstract: An alternator driven by an internal combustion engine in a vehicle is deactivated, e.g. by switching off the excitation of the field coils, in response to sensed conditions. This can be during start up or idling of the engine (to reduce the load on the engine and exhaust emissions), during periods of heavy loading on the engine (to maximise the power available) or when the battery in the vehicle is sufficiently charged, e.g. to 95% of its full capacity, the alternator being reactivated when the charge drops below 90%. If the voltage output monitoring circuit of the alternator fails the excitation coils are pulsed to give a maximum output greater by 1.5 to 2 volts than the normal voltage of the battery.

Abstract: A pneumatic fluid control valve includes a valve body having a fluid inlet 24 connectable to an external source of pressurized pneumatic working fluid, one or more load outlets, one or more 26,28 corresponding exhaust ports 30,32 and a movable valve mechanism 46-54. The movable valve mechanism includes at least a pair of movable valve element 46,48,50 and resilient deformable connectors 47,49 in a generally abutting relationship between adjacent movable valve elements for deformably transmitting coordinated motion therebetween. The deformable connectors resiliently allow one of the movable elements to move and compress the connector before such coordinated motion is transmitted to the other movable element in order to minimize internal leakage. The deformable connectors may be in the form of a spring or a hollow tube (see figure 9). One of the valve elements may comprise two half elements.

Title: Voltage stable ring oscillator
Inventor: HERZEL FRANK
IPC: H03K3/03
Filed: 1999-09-13
Abstract: A ring oscillator is operated from two negatively correlated supply voltages, instead of from the usual one supply voltage. An auxiliary supply voltage VDD2 is generated from the supply VDD by means of an inverting amplifier, such that VDD2 decreases if VDD increases and vice versa, m stages of an n-stage ring oscillator operate from VDD2 and the remaining stages from VDD. This arrangement reduces the oscillator's frequency sensitivity to fluctuations in supply and/or substrate voltage, therefore, the frequency exhibits less jitter due to the noise in these voltages.
