Title: Two-stroke engine closed loop control device
Inventor: TSUEI JIN-TORNG
IPC: F02B75/02
Filed: 1991-11-15
Abstract: An exhaust oxygen detector 32 comprises an exhaust duct 33, a sampling valve 34, and a sensor 35. The duct 33 is connected to an exhaust inlet 31 disposed in the wall of the cylinder 25 or the exhaust pipe 25 adjacent the cylinder. The valve 34 is opened and closed before the air inlet port 23 is opened on the power strokes so as to permit exhaust gases to pass therethrough and contact the sensor 35. The sensor signal is transmitted to the engine control unit 10, which controls the fuel injector 171 to provide an optimum air-fuel ratio. The valve 34 which is opened by the exhaust pressure may be replaced by a mechanically-operated valve. <IMAGE>

Title: Induction heating apparatus
Inventor: JACKSON WILLIAM BARRY
IPC: F27D99/00
Filed: 1991-12-03
Abstract: Induction heating apparatus for heating an elongate metal workpiece of predetermined width has means to generate time varying magnetic fields which produce longitudinal eddy current distributions across the width of the workpiece having cosine and sine profiles. The amplitude of these profiles is not necessarily uniform across the width of the workpiece and the spatial period of these profiles across the workpiece width are chosen to ensure that the line integral across the workpiece of the eddy currents is zero. In this way a desired heating profile across the width of the workpiece can be maintained.

Title: Mounting terminals in an electrical connector.
Inventor: SAWADA YOSHITSUGU
IPC: H01R24/00
Filed: 1992-09-24
Abstract: A connector assembly for connecting an electric wire to a printed circuit board has means indicating that the terminals of the wire have not been fully inserted. The assembly includes a housing body having a terminal accommodating chamber formed therein. In one example (figure 4c), an insulating cover (43) is hinged at one end on the housing body (11) and has an extension (46) forming a detecting projection so that, when a terminal (39) is not accommodated in the correct position in the terminal accommodating chamber, the terminal interferes with the detecting projection (46) of the cover to prevent pivotal motion of the cover to a predetermined position. Alternatively (figure 9), a terminal retainer (73) is slidable to place a projection (81) behind an inserted terminal, to prevent removal. An incorrectly inserted terminal interferes with the projection (81), to prevent retainer sliding. A cover (54) is then prevented from sliding into retainer grooves (75). Covers (43 and 54) expose a contact projection (38, 66) for mating with printed circuit tracks passing into a housing receiving cavity. <IMAGE>

Title: Thermal path to a thermal cut out/boiling sensor for an electric immersion     heating element
Inventor: O'NEILL ROBERT ANDREW
IPC: H05B3/82
Filed: 1993-02-19
Abstract: An electric immersion heating element for a water boiling vessel has associated therewith a single thermal sensor which protects the element against overheating due to its being switched on when dry and also serves to switch off the element when water boils in the vessel. The heating element is of traditional construction with a sheathed wire-wound element proper affixed to a head plate and with a hot-return portion of the element proper affixed to the head plate to enable the element temperature to be sensed on the opposite side of the head plate, but the element sheath and the head plate are formed of stainless steel (or another material having a low thermal conductivity as compared to copper or brass), the fixation of the element hot return portion to the head plate is by means of a spot weld (or another highly localized fixation), an enclosure is provided on the element head in the region thereof whereat the element hot return portion is affixed and is arranged so that water fills the enclosure when the vessel is filled but is expelled therefrom by steam generated by water boiling in the vessel, and the single thermal sensor is arranged to be in close thermal contact with a highly localized area of the head plate corresponding to the location whereat the element hot return portion is affixed thereto on the opposite side thereof.

Abstract: The system assays a reduced-form substrate Bred and either an oxidised-form substrate Box or a reduced-form coenzyme Ared, using a dehydrogenase catalysing the reaction between Ared and Box to the corresponding oxidised-form coenzyme Aox and reduced-form substrate Bred, and an oxidase catalysing the oxidation of Bred. The system includes a first measuring part, including the oxidase in immobilised form 4 and an electrode 5 for detecting an electrochemically detectable substance involved in the enzyme catalysed reaction. A second measuring part comprises, in order, immobilised dehydrogenase 6, immobilised oxidase 7, and a second electrode 8. As shown, buffer solution containing NADH is pumped to sampler 3, where a sample containing L-lactic acid and pyruvic acid is injected. In vessel 4, containing L-lactate oxidase, pyruvic acid and H2O2 are formed from the L-lactic acid, the H2O2 being determined by electrode 5. In vessel 6, containing L-lactate dehydrogenase, pyruvic acid, both from the original sample and formed in vessel 4, reacts with NADH to form L-lactic acid and NAD, the former being oxidised, in vessel 7 which contains L-lactate oxidase, to generate H2O2 which is sensed by electrode 8. The outputs of the electrodes are converted to digital signals and sent to computer 13. <IMAGE>

IPC: A47C1/025
Filed: 1994-11-21
Abstract: The apparatus has lower arm 1 for securing to a seat cushion and an upper arm 2 for securing to a seat back. The lower arm and upper arm are rotatably mounted on a rotatable shaft 3 but are normally secured against relative rotation by a pawl-and-ratchet locking mechanism 51, 52. The paw can be disengaged from the ratchet via a cam 41a upon rotation of the shaft 3, to permit adjustment of the seat back. A load sustaining mechanism is provided between the lower arm and the upper arm to sustain the reaction force which would otherwise be applied to the rotating shaft if a load is applied to urge relative rotation between the lower and upper arms when the paw and ratchet are still engaged. The load sustaining mechanism may comprise an arcuate protruding portion 62 formed on the lower arm, and an arcuate groove 61 formed on the upper arm for receiving the protruding portion, and a clearance is defined between the shaft and the upper arm. <IMAGE>

Title: Using data-recording devices
Inventor: COX ROGER WINSTON
IPC: F21V33/00
Filed: 1994-12-21
Abstract: Casings for data-recording devices are disclosed which consist of a housing (4) having a closable chamber (6) for receiving and retaining a data-recording device. The lid (8) of the chamber includes a region (10) of transparent flexible material through which the data-recording device is visible, and its inputting keys may be depressed. Integral with the housing are two compartments (12 and 14) containing light bulbs. A handle 26 is mounted onto the housing so that the casing may be supported in one hand alone. The casing facilitates the task of a meter-reader especially when a meter is installed in a dark location since by switching the light bulbs on and directing compartment (14) towards the meter the meter data display and data-recording device are simultaneously illuminated, and the data may be input through the flexible section of the lid with the hand not supporting the casing. <IMAGE>

Patent GB-2292179-A (GB)
Title: A gripping device
Inventor: KIRK IAN ALISTAIR
IPC: F16B7/14
Filed: 1995-08-14
Abstract: A gripping device (10) is described which has an inner member (14) and an outer member (12). The inner member has a split (20) which defines a first end (6) and a second end (8). A selectively operable device (18) is also included to keep the first and second ends (6, 8) apart to permit the device (10) to be placed around an object (30) and to permit the first and second ends (6, 8) to move towards each other so that the inner member (14) grips the object (30). At least part of an outer face (26) of the inner member (14) interfits with at least a part of an inner face (22) of the outer member (12) in a manner such that when a load is applied to the outer member (12), the inner face (22) of the outer member (12) acts upon the inner member (14) to cause compression of the inner member (14) thereby increasing the grip of the inner member (14) on the object (30). The device (10) is then locked in position on the object (30) and when the load is removed the action of the outer member (12) on the inner member (14) is reduced thereby decreasing the grip of the inner member (14) on the object (30) and unlocking the device (10) from the object (30). <IMAGE>
