Title: Commodity consumption registering meters
Inventor: JONES ALAN JOHN
IPC: H04B1/40
Filed: 1996-03-15
Abstract: A commodity consumption registering meter includes a transceiver (5) which comprises a transmitter (9) operative to transmit consumption data to a base station, a receiver (12) operative to utilise a local oscillator (11) to effect conversion of a received signal to a demodulated signal, and control means (2) for adjusting the frequency of the local oscillator in response to the received signal to reduce drift in the frequency of the local oscillator. The difference in frequency between the received carrier and the local oscillator (11) may be measured via the counter (19) to control the local oscillator. Alternatively the received signal may be modulated with data indicative of the amount of frequency correction or of the required local oscillator frequency and the recovered data is applied to a processor for control of the local oscillator. The control signal may be corrected by the output of a temperature sensor. The control signal may be stored in a memory 4 when the transceiver is in the stand-by state.

Title: Attenuator for borehole acoustic waves
Inventor: HSU CHUAR-JIAN
IPC: G01V1/52
Filed: 1996-09-11
Abstract: An attenuator for use in attenuating tube waves in a borehole includes a body 10 formed from a permeable material having a rigid matrix which can be saturated with fluid. In its simplest form, the attenuator is one or more cylindrical bodies 18 as part of a borehole acoustic logging system. Alternatively, the shape, particularly at the end regions, can be modified to reduce the amount of reflection of tube waves in the borehole. Suitable material is permeable rock, synthetic rock or sintered particulate material. Another attenuator (Figure 7) includes a body (110) for placement in a borehole formed from an attenuating material, the shape of the body being selected such that the change in impedance experienced by acoustic waves in the borehole is gradual rather than abrupt. One particularly preferred shape for the body comprises one in which the diameter is greatest towards the center of the body (114) for example the shape formed by two cones placed base to base, or a cylinder having conically tapered ends. A number of bodies can be used where appropriate.

Title: Producing a catalyst body
Inventor: SEKO HIDEO
IPC: C25B11/08
Filed: 1996-11-20
Abstract: A catalytic body, especially for use as an anode in a fuel cell, comprises a moulding of conductive material to which platinum and ruthenium are applied. In the method of the invention, the body is first impregnated with a solution of a platinum compound (for example, platinum chloride). After drying, the platinum compound is reduced in a hydrogen atmosphere to give metallic platinum. Secondly, the ruthenium is applied by an analogous process, ruthenium chloride being the preferred compound, and reduced to the metal. The support comprises a conducting material, preferably carbon, and a water repellent material, such as PTFE. A fuel cell is exemplified, comprising the anode formed into a composite with a cathode of similar construction (but lacking ruthenium) and a cation exchange membrane sandwiched between them. The joint electrodes are shaped into a disc and are used to generate electricity from hydrogen and oxygen.

Patent GB-966311-A (GB)
Abstract: 966,311. Electric measuring bridges; potentiometric measurements; measuring temperature electrically. HAGAN CONTROLS Ltd. Dec. 22, 1960 [Dec. 23, 1959], No. 44047/60. Headings G1N and G1U. In a combination of two bridge circuits both energized from the same A.C. source, adjacent branches of a first bridge contain condition sensing elements that unbalance the bridge as the condition sensedby one element relative to the other changes, contiguous sides of the second bridge consist of a potentiometer with a sliding contact, and means are provided responsive to changes in the out of balance voltage of the first bridge to shift the sliding contact of the potentiometer until the out of balance voltages of both bridges are equal. The bridge 10, Fig. 1, contains temperature sensitive resistances RT1 and RT2 which cause a voltage signal Eo to appear across the bridge approximately proportional to the temperature difference T2-T1. The difference between Eo and the voltage signal Ep across the second bridge 11 actuates the circuitry 19 which causes the wiper 18 of a potentiometer 17 in the bridge 11 to be driven until Eo=Ep. The value of Eo may then be read from the position of the wiper 18. The circuitry 19 is shown in Fig. 2. The difference voltage Eo-Ep is applied via a transformer 28 to an amplifier 19, the A.C. output of which is applied to the shade coil windings 35, 36, 37, 38 of the reversing motor 30, which is provided with an A.C. primary winding 39. The motor 30 drives the wiper 18 on the potentiometer 17 until the effect of the shade pole windings is zero. Both bridges are energized from the same A.C. source by means of secondary windings on the transformer 12, to whose primary the A. C. is applied.

Title: Minimising water re-entrainment in fuel filters
Inventor: BLANCO EDUARDO ALLER
IPC: F02M37/24
Filed: 1998-08-07
Abstract: A fuel filter, comprising a wound filter element 12 arranged in a housing 11 above a space 25 for storing water separated from the fuel, is provided with means (porous sieve, deep bed filter or felt disc 32) to reduce the force of the filtered fuel as it exits from the filter element 12 by dividing it up into many small streams. This ensures that the fuel streams do not impinge as strongly as they otherwise would on the surface of the water in the water storage space, and so re-entrainment of water in the fuel is minimised. The fuel, preferably diesel fuel, enters through inlet 15, flows axially through filter element 12, through the felt disc 32, through a filter supporting ring 23, into the water storage space 25 and up through a central tube 22 to the outlet 17. The filter element is wound from a V-shaped web of filter material, with the folded edge at the bottom end, or (not shown) from two or more webs. The fuel filter may be a throw-away cartridge.

Title: A tape measure capable of locating the middle point of a measured length
Inventor: LI SHIH-LIN
IPC: G01B3/10
Filed: 1998-10-30
Abstract: Disclosed is a tape measure capable of locating the middle point of a measured length comprising two sets of center point subscales provided, one for each regular scale, one in metric system and the other in British system respectively disposed along each of the two parallel edges of the tape. The four sets of scales are all graduated from a common zero beginning point on the tape. Locating the middle point of a measured length is achieved by finding the point where the value indicated by a subscale being equal to the value indicated by a corresponding regular scale as the total measured length, this point is the desired middle point of that measure length. The measurement work can be carried out without depending on the operator's calculation either by his (her) own mental ability or with the aid of a portable calculator so that the measuring procedure is simplified and the efficiency improved.
