Patent GB-2283336-A (GB)
Title: Device and method of correcting the fuel ammount supplied to Otto engines
Inventor: GILLBRAND PETER
IPC: F02D45/00
Filed: 1993-06-30
Abstract: The invention relates to a device and method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to obtain the fastest possible response with the smallest possible number of calculations of the fuel flow, the invention is characterised in that it is the initiation of the opening or closing of the injection valve which immediately gives rise to a calculation of the instantaneous fuel demand. When the injector is activated for opening (61) or closing (60, 60'), an interrupt is generated which, in the case of automatic opening, activates one complete calculation of the instantaneous fuel demand on the basis of the parameters which are detected at the time of opening or, at the time of closing, on the basis of a limited number of parameters which are indicative of the load enrichment requirement at the time of closing. Calculation for closing can be completed by the microprocessor with a limited number of instructions before the injector has begun to close. Thus a counter-command for opening the injector, caused by the fuel enrichment requirement, results in a single coherent, but extended injection (55). <IMAGE>

Title: Automatic time of day calculation for a radio telephone, fax machine or comput er
Inventor: SEPPO ALANARA
IPC: H04M1/724
Filed: 1994-12-15
Abstract: To determine the time of day which is local to the destination of an outgoing call from a first telephone to a second telephone, or to the origin of an incoming call to the first telephone, the first telephone extracts the prefix of the second telephoned number containing trunk code data and uses that prefix, or a derivative thereof, as a search key to retrieve time differences between geographical areas located in different time zones. The time differences are stored in a memory of the first telephone. The local time at the second telephone may be indicated on a display at the first telephone. A similar arrangement may be used for a FAX machine or a computer attached to a modem.

Title: Safety kettle
Inventor: MUSTARD GEORGE
IPC: A47J27/21
Filed: 1995-09-25
Abstract: A safety kettle comprises a flap (1) which prevents the escape of water by covering the spout. The spout has a raised ridge which prevents the flap (1) from opening outwards. In order to open the flap for normal use, safety button (5) must firstly be pressed which then enables trigger 3 to be pressed thus opening the flap. This safety button and trigger must remain pressed during operation. On releasing these buttons the flap will automatically shut. One or more steam valves (Fig. 2 and 3) located on top of the kettle body allow the steam to escape. These valves are designed so that should the kettle be tilted or upturned, a sealing disc blocks off the steam valve outlets, preventing the escape of water. These valves return to the open position when the kettle is returned to the upright position.

Title: A control shaft and method for its manufacture
Inventor: BEIER ALFRED
IPC: F16D1/072
Filed: 1996-03-13
Abstract: To secure axially a control element (2), such as a cam, on a shaft (1), the control element (2) is pushed onto a region (3) provided with a slightly larger diameter (D) than the remainder of the shaft (1), displacing material in the process to form a burr (15), and then, by means of a punch (17), another burr is produced on the region (3) on the opposite side of the control element by the displacement of material. The control element (2), which is preferably formed by a multiplicity of layers (4) of flat stock, is thus held axially in a positive manner on the shaft (1), in both directions of the latter by the respective burrs. The shaft may be an engine or injection pump camshaft.

Title: Two stage linear and low noise operational transconductance amplifier with low power supply voltage
Inventor: KIMURA KATSUJI
IPC: H03F3/68
Filed: 1996-10-14
Abstract: A bipolar or MOS OTA is provided, in which no S/N degradation occurs due to compression and expansion of a signal, and low voltage operation can be realized at a power supply voltage of approximately 2 V for the input voltage range of approximately 1V peak-to-peak or greater. This OTA includes a first differential pair of first and second transistors Q1 and Q2 respectively driven by first and second current sources or sinks. A first resistor R1 is connected to emitters or sources of the first and second transistors. A differential input signal is applied across these emitters or sources. This OTA further includes a second differential pair of third and fourth transistors Q3 and Q4. A second resistor R2 is connected to emitters or sources of the third and fourth transistors. A current path is connected to the emitters or sources of the third and fourth transistors, thereby allowing a current to flow through the second resistor. The connection of the first and second pairs are so designed that each of the currents flowing through the third and fourth transistors contains a component proportional to the input signal. An output signal is derived from one of the emitters or sources of the third and fourth transistors.

Title: Protective sleeves for timber joists
Inventor: SIBLEY ROBIN MARK
IPC: E04B5/12
Filed: 1996-12-02
Abstract: A means to protect and preserve the ends of timber joists, whereby a preformed impervious protective sleeve incorporating a sponge containing a measured quantity of wood preservative, in liquid or emulsion form, is used to protect the ends of timber joists or the like from decay; the protective sleeve is placed over the end of the timber joist and the sponge compressed to release the wood preservative.

Title: Wire cassette for a stitching machine
Inventor: SIKORA LARRY A
IPC: B27F7/28
Filed: 1997-04-07
Abstract: A supply wire cassette 50 is removably mounted on the face plate of a wire stitching machine head 20. The cassette carries a rotatable reel 101 of wire from which wire 130 is unreeled over a flexible, resilient brake lever 110 through a check pawl 88 and a guide tube 80, which guides the unreeled wire along an arcuate, wire-straightening path to an outlet at a cutter on the head. A wire holder 120 is removably mounted on the cassette housing and holds the free end thereof in position at the outlet until the cassette is mounted on the face plate to ensure that the wire passes through the feed mechanism of the head. Actuation of the feed mechanism withdraws wire from the cassette, pivoting the brake lever to unbrake the supply reel. When a predetermined length of unreeled wire accumulates in the cassette housing, the brake lever is biased back into braking engagement with the reel. A sensor including a switch 105 removably mounted in the cassette housing indicates when the supply reel is nearly empty.

Title: Elevator dispatch system
Inventor: SAKITA MASAMI
IPC: B66B1/14
Filed: 1997-04-07
Abstract: In an elevator control system the amount by which an estimate of the passenger demand for travel in one direction exceeds the level that can be provided by the elevator cars currently operating is determined. When this is equal to or exceeds a preset threshold level, an elevator car is dispatched from a terminal floor to help meet demand. The threshold level can be zero so that an elevator is dispatched as soon as estimated demand exceeds the capacity currently available or may equal the maximum capacity of a car so that a car is only despatched when it is likely to be filled. In one embodiment (figure 12) an elevator car in an adjacent shaft may act as the counterweight for another car.
